Actions from Last Week

cheng to dig into connection reset issues with SSL
- Looks like it’s probably related to just a few specific sites. FWIW, complaints seem to have died down this week so dunno (although a few of the previous threads ended in “I’m just switching to Chrome”)
irina to let us know whether dolphin for iOS uses Sync
- Dolphin can sync data in 2 ways: through a feature inside the browser which is called Dolphin Connect and through an add-on which is called Firefox Sync for Dolphin HD, which is the one using our mechanism. Dolphin Connect can only sync bookmarks and it is present on iOS and Android inside the browser. The add-on, Firefox Sync for Dolphin, is not present on iOS, only on Android.

Schedule & Progress on Upcoming Releases

Firefox Desktop

Release (3.6, 10)

FF 3.6.27 and FF/ESR 10.0.2 released last Friday due to security concerns
FF 3.6.27 -> FF 10.0.2 MU pushed out last week as well

Beta (11)

Firefox 11 Beta 4 will be released Friday
Firefox 11 code freeze is a little over a week away, on Friday 3/2

Effort underway to bring old beta users to the latest version using automatic updates (typically used for minor updates) as opposed to advertised updates
- This is a more aggressive approach since incompatible add-ons will not be reported prior to update, and the update is automatically downloaded.

Aurora (12)

Nightly (13)

Some nice UI cleanup and beginning Australis prep work has happened in the last week.

Dão fixed bug 702225 – Implement revised nav bar button appearance on Windows and bug 631250 – Status overlay switches to right side of window when find bar is open and bug 727793 – Status panel tracks the mouse position on the wrong side when using a RTL locale
heycam fixed bug 674370 – [10.7] Support animation when opening windows in Lion
Jared fixed bug 709182 – “connecting” in tab title when reloading is unnecessary visual noise and bug 722681 – Show the tab close button immediately when the second tab of a window is opened
mak fixed bug 720258 – Inline autocomplete should only autocomplete URLs you’ve typed
ttaubert fixed bug 725200 – about:newtab briefly shown in location bar of new tab
Joshua M fixed bug 726259 – bookmarks toolbar top border and bug 729293 – Reduce border-radius on nav-bar to match Australis design

Feedback Summary

Desktop

Firefox 10: (Lots of add-on complaints)
- Real player video downloader doesn’t work [1][2][3]
- Download youtube video extension bundled Skipity (which is some kind of search/content injecting thing that makes you log into facebook to use) [4][5]
- Foxtab doesn’t work with the latest flash player update [6][7]
- And because it’s that time in the release cycle: Lots of searchware:[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]
- Complaints about 10.4 support (or lack thereof): [28][29][30]
- Youtube issues: [31][32][33][34]
- Performance: [35][36][37][38] suggests that it’s bitdefender.
Firefox 11:
- Performance seems to be edging worse: [39]
- Websites: [40](netflix)[41]

Mobile

Just read the wiki.

Top dissatisfiers on mobile according to the android market continue to be flash and performance-related issues. New filtering of android market reviews is now available, making it much easier to assess the negative reviews and get more data about makes/models for each review, so the analysis going forward should be a richer set of data.
Re-planning documentation updates for tablet to match new schedule for nativeUI (we scaled back tablet changes because of nativeUI, now that nativeUI has slipped, tablet docs could use some love).
Working on docs for add-ons, security and privacy for nativeUI beta.

UX & User Research

Market Insights

Desktop / Platform

Adobe

Adobe released a roadmap for Flash, which focuses on improved support for gaming and video. At the same time, they announced via a blog post that in future, only the version of Flash for the Pepper Plugin API will be supported on Linux, effectively meaning that Flash will only be available on the platform with Google Chrome or Chromium. After version 11.2, the NPAPI version of Flash will only receive security updates.

Google

Google was the subject of a significant amount of press coverage this week when the Wall Street Journal revealed that Google’s +1 button system was taking advantage of a WebKit bug in Safari to allow scripted POST calls to override the browser’s rules on third-party cookie collection. Microsoft made a similar claim that Google’s incorrect use of HTTP P3P headers allowed it to set third-party tracking cookies. Google replied that the Wall Street Journal story “mischaracterized what happened and why” and that MSIE’s implementation of P3P is not functional in today’s web.
CNET interviewed Google Chrome VP Sundar Pichai. He noted that Chrome is part of a larger ecosystem that includes Native Client, the Chrome Web Store, Chromebooks and Google Apps, all of which he said have long run revenue opportunities. He also said that Google has always taken an open, standards-based approach to their initiatives, that they see businesses and schools as solid opportunities for Chromebooks, and that upcoming improvements will feature a significant amount of GPU rendering to improve the experience on slower hardware like Chromebooks. Newer, faster Chromebooks will be arriving soon, which will support 64-bit architectures.
A Google Chrome engineer made an interesting blog post about how Chrome on Android handles low memory situations — it first selectively kills background tabs, then clears memory caches and performs garbage collection. Finally, when the system can allocate memory no more, it kills Chrome’s renderer process in which the web page lives. Many mobile browsers would crash entirely, but due to Chrome’s multiprocess architecture, the browser keeps running and displays the “Aw, Snap!” page.
The Google Dart team released an initial development version of “Dartium”, a version of Chromium that includes the Dart virtual machine. Currently only available in Mac and Linux builds.
Google announced that that their public DNS service now receives 70 billion requests a day, with 70% of traffic coming from outside the USA.
The Chrome team is also proposing a feature in Chrome that would automatically generate passwords. They describe their longer-term goal as OpenID, but this feature as a necessary interim stopgap for improved security.

Microsoft

Microsoft quietly announced that consumer security support for Windows 7 and Windows Vista would be extended from five years to ten.
Microsoft, in a blog post, described how they built a MSIE performance testing data center of 140 machines hosting a “mini-Internet. It tests the performance of builds 200 times daily, collecting over 5.7 million measurements and 480GB of runtime data each day from 850 different types of metrics.

Apple

Apple released a developer preview of Mountain Lion, the upcoming version of OS X to be released this summer. At this stage it looks like the most significant change for Safari will be an integrated search / address bar.

Opera

Opera purchased two mobile advertising companies.
An independent developer, using Opera’s APIs, released a product equivalent to Firefox Home on iOS. Opera Link is available in the Windows Phone Market.

Security

McAfee released their 2011 Q4 Quarterly Threat Report (PDF report). The number of malicious URLs continues to rise, jumping by more than 5 times during 2011, to more than 700,000 active malicious URLs.
Adobe patched seven critical vulnerabilities in Flash Player that took advantage of a cross-site scripting bug in MSIE. Adobe noted that even if its upcoming sandboxed MSIE Flash Player was available, the XSS-based attacks would still have worked.

WebKit

In WebKit development this week, the Web Inspector now has a tool for reviewing IndexedDB databases, as well as a color picker, and two new CSS properties were added: -webkit-line-grid and -webkit-overflow-scrolling, and all HTML elements now support the translate attribute. Support for the CSS calc() function and the VibrationAPI also arrived.

Tizen

The first Tizen Conference has been announced for May 7-9 in San Francisco.

Mobile

Summary below, full update here and in your inbox.

Rumours on Jelly Bean launch next quarter not likely to be true

Tegra 3 devices coming out this quarter

Opera bought 2 mobile advertising agencies to focus on the US and European markets

Next version of OS X goes towards deeper integration with iOS and iCloud

RIM released BlackBerry Playbook OS 2

Software Carpentry: Should We Relocate Our Repository?

Greg Wilson — Thu, 23 Feb 2012 02:48:59 +0000

Software Carpentry has been an open project since 2004: MIT License for the code, Creative Commons for everything else. All our stuff has lived in a public Subversion repository since then as well—it’s at http://svn.software-carpentry.org/swc if you want to check it out. Today’s question is, should we move that repo off our server and onto GitHub, BitBucket, or some other repo-hosting service? We want to make it easy for people to remix our content; as I said back in December, that means making it easy for them to fork, merge, and share. Would you be more likely to do this if our slides, learning plans, diagrams, and code samples were on some well-known hosting site rather than in Subversion on our own machine?

Mozilla Add-ons Blog: Re-packaging your SDK-based Add-ons for Firefox 11

Jeff Griffiths — Thu, 23 Feb 2012 00:11:21 +0000

Yesterday the Jetpack project released SDK 1.5. Alongside this Dave Mason pointed out that the upcoming release of Firefox 11 will break compatibility with add-ons packaged with SDK versions 1.3 and below. This is necessary because of a change in Firefox where nsIDOMNSElement was removed ( Jorge recently mentioned this in his compatibility post ). Add-on SDK 1.3 and below contains code that uses this api, and SDK 1.4.* and up do not.

If you are an add-on developer who has an SDK-based add-on on AMO, what this actually means is the following:

You do not have to change your own code at all.
If you are doing development on your own machine using the command-line SDK, you do need to download the latest version of the SDK and re-package your add-on with this new version.
If you are doing development with the online add-on builder, the process is even simpler – just switch the version of the SDK being used in your builder project and click on save, as I demonstrate in this incredibly short screencast.
Once you have an updated xpi file, please submit it to AMO. As the AMO approval queues are at historically low levels currently, I expect your review should be dealt with promptly!

We’d really appreciate it if developers would do this some time before Firefox 11 ships on March 11. We will also be using the powers of AMO to directly contact affected developers over the next couple of weeks as well. If you have any questions about this, please comment below or drop by #jetpack on irc.mozilla.org.

Mozilla Add-ons Blog: Add-on Builder 1.0 is Ready for Liftoff!

Daniel Buchner — Wed, 22 Feb 2012 23:21:59 +0000

After a year in incubation we’re ready to remove the beta tag from the Add-on Builder! For those of you who are unfamiliar with this fantastic tool, Add-on Builder is an online development environment that allows developers with knowledge of HTML, JavaScipt and CSS to rapidly create add-ons for Firefox using the Mozilla Add-on SDK. You can think of it as the jsFiddle of add-on development and debugging.

Add-on Builder leverages the Add-on SDK to produce add-ons that users can install without restarting Firefox. In addition, add-ons created with Add-on Builder are automatically repackaged with Add-on SDK updates – which ensures that Builder-based add-ons will continue to work for users without interruption, regardless of Firefox API changes.

Add-on Builder provides many features specifically tailored to help add-on authors develop add-ons:

a simple online interface for writing your code
live, one-click add-on testing
access to a repository of third-party add-on libraries
jsFiddle-like sharing and collaboration
instant upgrade options for new versions of the Add-on SDK
integrated features for publishing to addons.mozilla.org

If you haven’t yet developed an add-on for Firefox, we suggest you give the Add-on Builder a try. With a simple interface and many helpful tools, it truly is the quickest, easiest way to create add-ons for Firefox!

hacks.mozilla.org: Save the Date: MDN Hack Day Comes to NYC on March 24

Havi Hoffman — Wed, 22 Feb 2012 22:57:05 +0000

A bunch of us Mozilla Developer Network folks — web developers, technical writers, developer evangelists and cat herders like me — will be hosting MDN’s first Hack Day in the great city of New York.

Like many teams who work together at Mozilla, we’re geographically dispersed, and manage to meet in real life a few times per year. The U.S east coast is a relative mid-point between Western Canada, California, Colorado, Oklahoma, Texas and Tennessee on the one hand, and France, Great Britain, Sweden, and Switzerland, on the other. So we’re headed for Brooklyn and the Big Apple!

On Saturday, March 24, we’ll be at New Work City, a splendid coworking space, which aims “to make the world a better place by empowering people to make a living doing things they love.” (That sounds like us!) We’ll open with a series of short talks about our projects and technologies, and after lunch we’ll hang out and hack, closing the day with demos.

We know that New York City is home to a flourishing tech scene with a thriving startup culture, influential venture firms, and lots of opportunity for developers. The hacker ethic is alive and well in NYC through the work of many collaborators, including: our Mozilla Foundation colleagues at The Hive Learning Network; WebFWD partner General Assembly, putting together a campus for technology, design, and entrepreneurship; and The Creators Project, which will be in San Francisco the weekend before, March 17-18, with a spectacular audio visual installation and other works of astonishing goodness.

We’re eager to meet, explore, and share some of the stuff we’ve been working on: HTML5, gaming, developer tools for Firefox, the evolution of Jetpack, open-source documentation, and roadmaps that support brand new open platforms and projects. We hope you’ll come check out what we’re building on the open Web and see if we can work together.

Mozilla is a non-profit with a mission to “to promote openness, innovation and opportunity” and a manifesto describing the “principles that we believe are critical for the Internet to continue to benefit the public good.”

Let’s hack together — in a city that embraces innovation — and never sleeps. Space is limited, so sign up now, and we’ll save you a t-shirt!

Identity at Mozilla: Introducing Mozilla Persona

Wed, 22 Feb 2012 20:54:00 +0000

This past year we’ve been building the core of a Web-scale identity system. We’ve been calling it BrowserID: our name both for the technology¹ and the Mozilla service that implements the technology. Today we’d like to introduce Mozilla Persona, our new name for the complete Identity offering from Mozilla: a collection of components and experiences we’re designing to manage the whole of a user’s online identity with our core values of user control, safety, and convenience.

The Persona name resonates with the idea of personhood as well as online identity as a facet of our lives, and therefore strongly tied to user identity. We’re very excited about this new name and the new features our identity system will offer. Some of the things we’re planning: an identity dashboard, user data interconnect features, and more.

What about “BrowserID?”

BrowserID remains the developer-facing name of the protocol. Websites, email providers, and browser implementors will continue to refer to the BrowserID protocol.

Over the next few months, we will begin to transition the Mozilla Web-based implementation of the BrowserID pop-up over to the new name. But don’t worry, we’ll work hard to make sure the transition is completely seamless for everyone.

Wait, what about Firefox’s Personas?

For the past few years, many Firefox users have enjoyed “Personas”—a quick and fun way to theme the background of the Firefox toolbar. The Addons team blogged about changing their name a couple of weeks ago. No doubt there will be some confusion during this transition, so if you have ideas for how to make the transition smoother, definitely let us know! We believe the long-term value of the Persona name will far outlast the short-term discomfort of change.

We hope you’re as excited about this change as we are. We look forward to an action-packed 2012 for our distributed Identity system under the Mozilla Persona umbrella!

As always, feedback and questions are always welcome on our mailing list, or by tweeting with the #browserid or #mozpersona hash-tag.

¹: Some of you may remember that BrowserID came from the Verified Email Protocol. We haven’t forgotten, of course—but BrowserID has become the name of the technology nonetheless.

Software Carpentry: Watch Me: Trial Run

Greg Wilson — Wed, 22 Feb 2012 19:54:04 +0000

A dozen people have come forward since I asked last week for volunteers to make short screencasts showing how they program. I just sent them a sample problem to work on to test things out (see below the fold); the videos they create won’t be made public, but I hope it gives readers an idea of the scale of problems we’re going to be looking at. If you have suggestions for interesting problems of a similar size, please add them as comments on this post.

Hello, and thank you once again for volunteering to help Software Carpentry by recording a screencast to show people how you program. To test out your system, I’d like you to record yourself solving the problem described below using any tool or tools you like, on whatever kind of computer you prefer. Use whatever recording tool you like (a demo version of Camtasia, QuickTime, xvidcap, …), and save in whatever video format is easiest. Please:

do use a headset mike if you have one, but if you don’t, please don’t worry about it for now—this is just a test
do use full-screen recording—the real videos will have to be constrained (probably to 800×600 or 1024×768), but for now, let’s keep it simple
do talk a lot while you’re coding—stream of consciousness like “OK, so let’s open up the editor again and try swapping those values in the other order…” is what we’re after
don’t worry about editing your video to cut out “ums” and “errs”, typing mistakes, and so on—we’ll do that for you in the real screencasts, and again, this is just a test

Write a command-line program called ‘total’ to add up the numbers in a data file. The input file’s name is given to the program as its sole command-line argument; its only output is the sum of the numbers in the file (if the file does not contain any numbers, the output is 0.0). The file may contain any number of lines (including none at all); each line may contain at most one floating-point number, and may also contain leading or trailing whitespace. (Lines containing only whitespace, or nothing at all, are allowed, and should be ignored.) For example, if the file ‘numbers.txt’ contains:

22
   31.3
 +5.0e1

-1

then invoking the program as:

$ total numbers.txt

should print 102.3 on a line by itself.

Web FWD: Ready to Stop Talking and Start Making with General Assembly

Wed, 22 Feb 2012 17:20:46 +0000

WebFWD is somewhat a “startup of startups,” having launched barely 7 months ago. So if there’s one thing we encourage, it’s the ability to move, act and adapt quickly. While we’re certainly keen to read and learn, we’re also big proponents of just getting stuff done.

So we were thrilled when we learned of General Assembly’s new program, “Stop Talking. Start Making.” A little context: General Assembly has been a force for entrepreneurial good in New York over the past year, launching an entire campus devoted to startup and business fundamentals. While we’re not knocking an MBA (some of us have them :p), there’s a lot to be said for hands-on learning. And now that the Web has lowered many barriers to entry, more people than ever are clamoring to start businesses… and need some skills and training to do so.

We were particularly struck by the approach that GA takes with “Stop Talking. Start Making.” In addition to getting experts who have really done this stuff themselves to share their knowledge, GA is sharing it all online, in the context of an interactive community, and making it available for free. Bonus: WebFWD Mentor Bre Pettis is involved ;)

As part of Mozilla, we at WebFWD considerably appreciate the power of open, interactive Web environments to foster true innovation. So we’re excited to contribute to this important project.

The Mozilla Blog: Mozilla Marketplace Opening for App Submissions Soon

ragavan — Wed, 22 Feb 2012 16:53:06 +0000

The Mozilla Labs Apps project aims to establish a people-centric Apps ecosystem that provides freedom, choice and opportunity for users and developers. We are doing this by adding key capabilities to the Web platform in the form of new Mozilla-proposed APIs and by establishing the Mozilla Marketplace as the first operating system- and device-independent market for apps based on open Web technologies like HTML5, JavaScript and CSS.

Today, we are incredibly proud to announce that the Mozilla Marketplace will open for developer submissions next week during Mobile World Congress. If you are an app developer interested in distributing and monetizing your app across device and platform silos, you should submit your app to the Mozilla Marketplace. Submitting your app will reserve your app name and give your app the chance to be featured in the launch later this year.

We believe the Web has no competition when it comes to nurturing creativity and generativity. And we cannot wait to see all the amazing apps that will be built using open Web technologies allowing developers to build apps once and deploy everywhere.

Stay tuned for more updates on the Mozilla Labs blog.

Software Carpentry: Granules of Research

Greg Wilson — Wed, 22 Feb 2012 16:05:17 +0000

Cameron Neylon recently posted an article titled “Github for science? Shouldn’t we perhaps build TCP/IP first?” His argument is that the web’s a good way to move text around, because it was built by programmers, and programmers work with text. It’s not (yet) well suited to moving science around, because we don’t (yet) have something as granular and portable as text for scientific ideas. Yes, any particular piece of research can be represented as text, but so can any image, or any audio stream, or anything else—it’s the structure that adds meaning, and we haven’t (yet) agreed on structures. Circling back to today’s first post, part of what we’re trying to do is give scientists the background to understand and take part in conversations like these…

Software Carpentry: What Deep Thoughts Look Like

Greg Wilson — Wed, 22 Feb 2012 14:01:06 +0000

Before writing yesterday’s post about assessment, I should have explained what I mean by”fundamental concepts”. I’ll start with Lewis Epstein’s wonderful book Thinking Physics:

Here’s a typical problem from the book. Put a block of ice in a bathtub, then fill the bathtub to the brim with water, so that the block is floating freely. When the ice melts, will the water level go up (causing a spill), go down, or stay the same? Hm… well, the ice displaces its own weight of water, so when it melts, it exactly fills the “hole” it made, so the water level stays the same.

Now let’s try something a bit more complicated. Put the same block of ice in the bathtub, but put an iron weight on top of it, and then fill the tub to the brim. Now what happens when the ice melts? Does the water level go up, go down, or stay the same? Epstein would say that if you can answer questions like that, then you can think physically. It isn’t about calculation—as with Dan Meyer’s “Joulies“, it’s about understanding principles and following them through to conclusions.

The real aim of Software Carpentry is to teach scientists to think like that about computing. We want people to understand the principles:

model-view separation
human-readable vs. machine-readable data
copying vs. aliasing
state machines
different models of computation (imperative, functional, reactive, declarative)
interface vs. implementation
the complementarity of algorithms and data structures
code as data (and data as code)

The Unix shell, Python, SQL, regular expressions, and what not are how we hook people (“Hey look, something useful”) and how we get these principles across (as with most big ideas, any direct description is either incomprehensible or banal). However, these principles aren’t natural laws in the way as F=ma and the Second Law of Thermodynamics—if you compare them to the principles I listed a month ago, there’s overlap, but the lists aren’t the same. So:

What is the best way (or a good, stable way) to carve up this intellectual space?
How do we tell what a particular person actually understands?

“Write this program” is not an answer to the second problem—as many studies have shown, people can solve routine problems by rote without really understanding what they’re doing. (This is the starting point for Eric Mazur’s work on peer instruction, and the reason so many of us are so skeptical about things like the Khan Academy.)

Can we just teach the tools (for some value of “just”) and let the big ideas sort themselves out? The answer is clearly “yes”, because that’s what I did from 1998 to 2007. Does it work? I think the answer is “only partially”: some people generalize from specifics to principles correctly on their own, but many either don’t do it at all, do it incompletely, or do it incorrectly. And does it matter? I think so: I think that if we want scientists (or anyone else) to use computing on their own, for their own ends, they need to be able to step past what we’ve shown them with good odds of success, and that certainly requires understanding “why” as well as “what”.

Bonjour Mozilla: Sofien Chaabouni (Chaasof)

clarista — Wed, 22 Feb 2012 09:00:00 +0000

(Photo : Nitot)

Il a représenté la Tunisie lors du Mozcamp à Berlin (et donc fait preuve d’un vrai talent pour obtenir un visa à temps !) : Sofien Chaabouni, alias Chaasof, le méritait sans conteste ! Depuis un an que la communauté Mozilla Tunisie est née, il est toujours pleinement investi, malgré le fait qu’il soit en dernière année d’études informatiques, entamant donc son projet de fin d’études.
Sofien a été le premier à répondre, il y a un an, à un appel de Melek Jebnoun, qui cherchait quelqu’un pour tenir le stand du premier événement de Mozilla Tunisie. Depuis ce jour, il se dévoue corps et âme, faisant preuve d’une générosité et d’une passion à toute épreuve. Connecté en permanence sur le canal Frenchmoz, il assure d’une certaine façon la connexion entre la communauté tunisienne et la communauté française, favorisant ainsi l’émergence d’une vraie communauté francophone, soudée. Sofien est un peu devenu le bras-droit de Melek : si vous voulez savoir comment va l’un, demandez à l’autre :-) Lors du Mozcamp, ému que Melek n’ait pu venir, il a passé son temps à la tenir au courant, l’appelant, lui envoyant des mails, des SMS. C’était très touchant. Enfin, Chaasof est un véritable boute-en-train : il ADORE faire la fête, est très doué au karaoké, ainsi que pour danser. Il est un peu foufou, mais c’est aussi ce qui fait son charme.

Bonjour Sofien !

He represented Tunisia at the Mozcamp in Berlin (and thus proved a real talent to get a visa in time!): Sofien Chaabouni, aka Chaasof, undoubtedly deserved it! Over the past year since the Mozilla Tunisia community was born, he has always been fully invested, despite the fact that he is in final year of his computer science studies, and so starting his graduation project. Sofien was the first, a year ago, to responda to Melek Jebnoun’s call for someone to keep the booth of the first Mozilla Tunisia event. Since then, he devoted himself body and soul, showing unlimited generosity and passion. Permanently connected on Frenchmoz, the Francophone community channel, he is somehow a link between the Tunisian and French communities, enforcing a true welded Francophone community. Sofien has sort of become Melek right arm: if you want to know how one goes, ask the other one :-) During Mozcamp, moved that Malik could not come, he spent his time to keep he up, calling, sending emails and SMS. It was very touching. Finally, Chaasof is a real live wire: he LOVES to party, is very good at karaoke and dancing. He is a little wild, but it’s part of his charm.

Bonjour Sofien!

Meeting Notes from the Mozilla community: SeaMonkey Meeting Minutes: 2012-02-21

SeaMonkey Meeting Details

Time: 21 February, 2012, 13:00 UTC
Location: #seamonkey IRC channel

Agenda

Who’s taking minutes? -> TBD
Nominees for Friends of the Fish Tank:
- Ratty nominates Lewis G Rosenthal. He has been tweaking install.rdf files and since November 2011 he has been helping Ratty to contact the authors of these tweaked extensions and encouraging them to make their extensions officially compatible with SeaMonkey.
- Please note A person or entity can’t be nominated twice in a row.

Action Items

(who needs to do what that hasn’t been recorded in a bug) We should assign people to the open items.

NEW

OPEN

IanN to write the “Friends of the Fish Tank” F.A.Q.

Status of the SeaMonkey Buildbot Master and Tree

Current Issues with existing machines:
- There are problems with some hosts on parallels, current plan is to build the Parallels VMs on ESX instead once scl3 has network and power to the new ESX cluster.
- One win VM, switched from FAT32 to NTFS for one of its drives, need to recreate folders appropriately.
“Where do we stand with the machine(s) right now?”
- bug 721516 migrate seamonkey systems out of sjc1/scl2 and into scl3/scl1.
  - (2012-02-07) “Currently the 13 HP’s have been moved to SCL3, and the 4 mac minis in sonnet chassis are at SCL2 and will be moved to SCL3.”
  - the 4 iX boxes are racked and powered at SJC1 on floor 14 rack 102.05, one of these is having hardware issues, an iX technician will be servicing.
  - + 4 blocking bugs.

Release Train

2.8b2 was shipped on February 9.
2.7.1 was shipped on February 10.
2.7.2 was shipped on February 17.
2.8b3 was shipped on February 18.

Extensions Compatibility Tracking

We need some help with the add-ons listed under the “2.0x” heading. Anything above it will work out of the box with SM 2.7 and later (yay to compatible-by-default!). Perhaps Ratty can go through his xSidebar site and check which add-ons are not compatible with at least SM 2.1 – that would help, too.

Since xSidebar itself is not compatible with any recent SM version, it should not be listed as a featured add-on on AMO. Who can make that change?
- KaiRo said he did, but it’s still featured for at least en-US and de locales.
- If anyone wants to suggest add-ons to be featured, send them to InvisibleSmiley (in manageable doses that is).

Addon Compatibility Listings, mostly maintained by InvisibleSmiley
- Recent changes can be found here.
- Restructured for compatible-by-default.
Enigmail provides versions for release (AMO) and all branches (Enigmail nightly page). The current release is compatible with both 2.6 and 2.7.
Lightning provides versions for the current stable and beta releases (AMO) and nightlies for trunk and Aurora (Calendar Versions page). Lightning 1.3b1 which works with SM 2.8bX is available from AMO (Development Channel).
Firebug is compatible but not flagged as such on AMO (depends on automatic tests being set up and run on the Firebug side: bug 680837, needs a Python coder). Stable Firebug version 1.9.x works with any recent SM version. FB 1.10a1 works with trunk, 1.10a2 and 1.10a3 are broken but next alpha should be OK again.
Besides the above, we should also take a look at other add-ons that are important for our users when they switch to 2.x.
- Useful query: https://addons.mozilla.org/en-US/seamonkey/extensions/?sort=popular
The SeaMonkey Features page links to sub-pages for all recent SM versions, including those in development. Please help InvisibleSmiley add major features to the respective pages, ideally as they land. These pages are used when creating release notes, so the more up-to-date the better.
bug 666303 (Seamonkey 2.1 is detected as Firefox 2.1 on the Add-on Site) and bug 671085 Confusing compatibility error when visiting Firefox listing page using SeaMonkey)
- We don’t have a dedicated person here who understands how AMO really works, who to contact in order to actually get things moving etc. Unfortunately. Someone needs to sit down and find the offending logic, wherever it may be (probably in the AMO source, at github).

2.x (Last, Current, Next)

2.7 had ~76,900 ADU by last Thursday and 2.7.1 has had ~25,700 and 2.7.2 has had ~9,400 downloads so far.
- Of the released versions, as of last Thursday, we have 16.8% on 2.0, 6.3% on 2.1-2.3, 4.9% on 2.4, 4.5% on 2.5, 11.0% on 2.6 and 56.5% on 2.7. So, in the last two weeks, ~2.8k (an additional 2.1% of ADU) have migrated to 2.6 or above.
Still a large, but slowly decreasing, chunk of users on 2.0.x.
Figure out what is preventing people from moving from 2.0.x to the latest versions.
- Some people cannot upgrade due to system requirements (OS version, processor capabilities etc.)
- Perhaps putting resources into getting certain extensions working with SM 2.4 and above (those that won’t work with SM 2.7 automatically due to compatible-by-default extensions).
- Still need volunteers to look at what is keeping people at below 2.4. IanN could try knocking something up and send it round members lists for polishing but he’s not on all the channels (mozillazine, etc) to post it to when finished.
- Are some Linux distributions are still stuck on 2.0? We have data on OSes and OS versions in the raw data in the Mozilla metrics, AFAIK, Callek now also has access to that.

Usual reminders:

Please make sure that anything that landed on comm-beta (for TB) or mozilla-beta (for FF) which affected non-shared code and which fixed regressions will be fixed on our side, too. Please mark bugs we feel *need* to land on a particular train tracking+ or tracking? so that when we to do a release we can be sure that we don’t miss anything.
- Priority should be given to fixing regressions ASAP. Also keep an eye on and prioritize bugs to be ported from FF/TB that land on branches (Aurora, Beta). We need to keep an eye especially on Session Restore, Sync, Tabbrowser and Address Book.
- Be careful not to break code shared with Thunderbird, otherwise patches might have to be backed out of string frozen repositories.

2.7

open tracking (0)
tracking requests (0)
targeted (0)
fixed (30)

One tracked 2.5 issue still open.
- 2.1 through 2.7 have NOT included the ka locale. The last release with ka locale shipped was 2.0.14 and the ka l10n maintainers have not yet updated for changes in later SeaMonkey versions.
- Callek now needs to morph bug 667147 into removing |ka| from our [current] automation entirely (all-locales). Callek will look at best locale to transition any ka users to.
  - Plan is to migrate ka users to en-US with a english dialog saying they are out of date, and a link to the all-locales page if there is a language they understand better. Current ADU of ka alone is 3-5 individuals, so low impact.~Callek
The New 2.7 Features page has a comprehensive list of features.

2.Next

InvisibleSmiley created a restartless add-on (available on AMO) for SM 2.8 (now in Beta) which adds an “Add-ons” options to the list of engines on the Sync pref panel.
Remember to help update the New Features pages as we go along.

Feature List, Planning

Bug statistics for last two (full) weeks: 57 new, 37 fixed, 14 triaged.

Good triaging effort.
Good further triage targets could come out of looking at the component bug counts, pick yours!

Open reviews/flags:
23 review
9 super-review
0 ui-review
8 feedback

Major wanted/needed features:

Active

bug 606683 Allow customization of toolbar in Composer and MailNews Composition [IanN].
- Progressing slowly, still waiting on reviews from TB side. Full customization has to go to 2.next (currently 2.10 but could be pushed back further) as it needs work on TB too which is taking a while to get reviews on, plus feedback from kaze.
- IanN is still wading through the unpicking of Composer/Mail Compose code in the dependent bugs. After that he will be reworking his customising patches.
bug 477845 Build a standalone (Comm-central) Composer. [kaze]
- kaze has done a bit of work in this bug recently. Building on Windows works. Now supports debug builds on Linux if tests are disabled (–disable-tests). Still a lot to do.
- The standalone Composer patch has to be rebased and fixed for MacOSX.
- Kaze is considering moving Kompozer to an addon so that we can reuse the dialog boxes but start fresh for the content part. Also we can then use the current devtools. KaiRo told kaze in Berlin it seemed a good idea, as it could allow to run a Composer *tab* instead of a Composer window.
- Kaze working on it on his spare time, with an Indian contributor.
- IanN was supposed to help get builds working with --enable-tests.
  - Will look into this once he gets his customization patches reworked.
Real full-screen (bug 610509) and DOM full-screen (bug 701714)
- patches provided by Mnyromyr and InvisibleSmiley. Otherwise stalled. :-(

Needing help, Unowned, Stalled

Kill-RDF:
- bug 657607 Port jminta’s kill-rdf to SeaMonkey where applicable Part 2 [meta].
- bug 657604 Remove the RDF global object. [serge]
bug 436794 Enable Mac OS X system address book per default and add UI.
- SM UI needed, unowned, helpwanted.
bug 449728 Drag tabs between windows.
bug 477840 Backport KompoZer to Composer (Depends on bug 477845).
- kaze has done a ton of work there. We still need to work out some organizational issues. At the moment there is no active interest from MoMo for bringing standalone composer into comm-central. That’s something we (KaiRo and kaze) will have to negotiate with the Thunderbird team (Standard8).
bug 507841 Port Bug 422814 – Make account configuration quick, easy, and more secure (autoconfig, Quick Account Setup).
bug 533908 SeaMonkey Mail: tabs not restored [misak].
bug 523274 Complete new default theme icon set.
- A list of TODO icons is up in the bug.
bug 526210 Update the icon set for the SeaMonkey Modern Theme.
- bug 548778 New communicator icons (based on Strata theme) for SeaMonkey. Some proposed icons got posted, we should take a look how to get that contribution into the product.
- The rest is unowned so far.
bug 87098 [SeaMonkey] Delete key should delete location bar history list entry.
- Note: Our location bar history doesn’t and can’t use autocomplete at all.
bug 677484 Individual SeaMonkey components are not properly handled by the Windows 7 taskbar.
bug 654009 Reply to list: automatically determine From: address
- Note: The actual task here is to port bug 45715 “Reply to List” [button/(context) menu item]
bug 664309 Make the built-in ChatZilla display a cZ icon in SeaMonkey (now helpwanted)

Addon Compatibility: I’ve been working with a SeaMonkey volunteer, Lewis G Rosenthal, to contact Firefox/Thunderbird extension authors and get them to update their extensions for SeaMonkey.

Paul Kolomiets, the author of Flexible Identity has added SeaMonkey compatibility to version 0.5.6 (Added to wiki last meeting).
I’ve made some minor changes to Select Address Book Text to get it working in SeaMonkey. Lewis will forward my changes to the author, Craig Markwardt.
Lewis tweaked the install.rdf for PrintingTools Thunderbird extension and tested under SeaMonkey 2.6. It seems to be fully functional, including printing from the address book. Email has been sent to the author requesting that he add SeaMonkey to the official install.rdf.
I’ve also received fixes to UrlParams and Quote Colors from InvisibleSmiley and uploaded these changes to my xSidebar modified extensions page.

Other:

Bug triage and Bug discussions.
End user support and PR in newsgroups and Mozillazine.

- Get someone to ASSIGN bug 716232 “SIGSEGV (segmentation violation) crash in Javascript at ChatZilla startup” to him/herself now that it’s known which hg changeset caused the regression

Any other business?

Need to review project areas
- IanN has put out a final version of the project areas list, and will hopefully be updating the wiki this weekend.
- We will also need to update the Mozilla-wide list of official reviewers
Extended Support Releases (ESR)
- At the moment looks like that will be based off Gecko 10 so that will be 2.7 for us. Assuming we have the machines, we will also have an ESR which might help move some of those still on 2.0 up to 2.7. We’re unlikely to move to ESR until Gecko 10.0.1 or 10.0.2.
- Our ESR should use the same branch as Firefox ESR so any Security and Stability “extended” fixes for Gecko will be picked up by the SeaMonkey ESR.
- An ESR (Extended Security Release) may not be a given for us out of the gate. Callek thinks we should revisit that, separately, once it is clearer what MoCo’s general plans for their marketing/target/support levels etc. are.
- mcsmurf is on the ESR mailing list is our ESR goto guy.
Geolocation
- Geolocation now works out of the box. MoCo turned it on by default for all applications that build off mozilla-central.
- For comm-beta all we need to do is (bug 494421) to add pref("geo.wifi.uri", "https://www.google.com/loc/json"); to browser-prefs.js. However we’re not even sure we are legally allowed to ship with the URL in, we might need to actually put in a pref to disable that in newer builds.

Socorro

Small Socorro release coming tomorrow, no major changes for developers.
Work being started to support ESR in Socorro within this quarter.
bsmedberg and ted are working on some stackwalking issues that cause wrong signatures or stack frames to appear:
- bug 726570 – MSVC2010 issues
- bug 709209 – browser-side hang signatures (even on MSVC2005)
- The patches in the former might fix the latter, but we don’t know for sure. Seems like they will improve stackwalking significantly in any case and might change signatures due to that.

hacks.mozilla.org: A simple image gallery using only CSS and the :target selector

Chris Heilmann — Wed, 22 Feb 2012 00:25:59 +0000

Back in the old days of web development and when CSS2 got support I always cringed at “CSS only” demos as a lot of them were hacky to say the least. With CSS growing up and having real interaction features it seems to me though that it is time to reconsider as – when you think about it – visual effects and interactivity should be maintained in the CSS rather than in JavaScript and CSS.

With the support we have in new browsers it would be a waste not to use what has been put in. If you have to give all the visual candy to IE6, OK, then you’d have to use a library like jQuery for your effects. But you can have your cake and eat it if you don’t give the shiny to the old browsers out there, but give them a simpler interface and make sure they don’t get what they don’t understand.

So today let’s take a look at an image gallery using the target selector. This has been done before (lightbox example, thumbnail preview example) but I thought it’d be good to explain the details of what is going on.

So here is a screencast of our “CSS only image gallery” in action and you can see it for yourself.

Starting with HTML

We start with HTML that works across all browsers (except for IE < 9, where you need a polyfill to style HTML5 elements):

<section class="gallery">
  <nav>
    <ul>
      <li><a href="#one">One</a></li>
      <li><a href="#two">Two</a></li>
      <li><a href="#three">Three</a></li>
      <li><a href="#four">Four</a></li>
    </ul>
  </nav>
  <article id="one" class="target">
    <figure>
      <img src="http://placekitten.com/g/300/200" alt="Kitten 1">
    </figure>
  </article>
  <article id="two" class="target">
    <figure>
      <img src="http://placekitten.com/g/300/201" alt="Kitten 2">
    </figure>
  </article>
  <article id="three" class="target">
    <figure>
      <img src="http://placekitten.com/g/301/200" alt="Kitten 3">
    </figure>
  </article>
  <article id="four" class="target">
    <figure>
      <img src="http://placekitten.com/g/301/201" alt="Kitten 4">
    </figure>
  </article>
</section>

Without any CSS this would just show all the kitten images in a vertical row and the links would point to them. This works, and should be more than enough for the IE6 users out there.

For browsers that support newer CSS, however, we can turn this into our gallery in a few easy steps:

Step 1: Position the articles

To make sure we don’t give IE older than 9 any CSS it chokes on, we can wrap all the selectors in a simple media query (in this case checking that the window is at least 400 pixels wide):

@media screen and (min-width: 400px) {
  ... all the good stuff ...
}

We then can give the gallery dimensions and an overflow of hidden to make sure that elements positioned outside of it will not be shown. We also position it relative so that every positioned child element will be positioned relatively to it:

.gallery {
  position: relative;
  height: 280px;
  width: 340px;
  overflow: hidden;
}

Then we position all the target elements absolutely in the gallery with 320 pixels to the left. This hides them off screen as we hide the overflow:

.target {
  position: absolute;
  top: 60px;
  left: -320px;
  height: 220px;
  width: 300px;
}

Now in order to show the image when the link to it was clicked we use the :target selector. This one assigns the CSS to the element when it was targeted – either by activating a link to it in the document or from the URL when the page loaded. With this pseudo selector, we override the left setting and move it to 20 pixels, thus showing the image.

.target:target {
  left: 20px;
}

You can try this out for yourself:

To make this smoother, all we need to do is to add a CSS transition to the target styles. Now all the changes to the styles will happen smoothly during a second rather than immediately.

.target {
  position: absolute;
  top: 60px;
  left: -320px;
  height: 220px;
  width: 300px;
  -webkit-transition: 1s;
     -moz-transition: 1s;
      -ms-transition: 1s;
       -o-transition: 1s;
          transition: 1s;
}

Again, see it in action and play with it.

That is all there is to it – the rest of the effects are just different variations of the same trick – animating opacity from 0 to 1 or CSS transitions.

Target selectors can be a very powerful trick. The main issue they have though is that the page scrolls to the target, so if there is a big distance between the link and the target you’ll get unsightly jumps.

Mozilla Add-ons Blog: Announcing Add-on SDK 1.5!

Dave Mason — Tue, 21 Feb 2012 23:34:49 +0000

The Jetpack team is pleased to announce the release of Add-on SDK version 1.5! This version of the SDK has two major new features as well as many smaller ones and some important bug fixes.

The two most important new features of this release are:

Mobile Support! – Developers can now start developing add-ons for the mobile version of Firefox. For the initial release of mobile compatibility we have the page-mod API working which will allow developers to create modifications to web content within their add-on. This is quite useful for creating mobile versions of website that do not have a good mobile support. This support for mobile Firefox is only for the new Native Android versions of Firefox (at time of this post, Aurora and Nightly). Primers on getting started developing add-ons for mobile Firefox can be found here and here.
Localization! – Localization has finally come to the Add-on SDK! For this initial version localizers can translate javascript-embedded strings with HTML string support coming in a future SDK release. An introduction on how to localize strings can be found in the documentation.

For more new features and known issues in Add-on SDK 1.5, please see the Release Notes!

As always, we’d love to hear from you about your experiences with this release. You can contact us in a variety of ways:

post to our discussion group
chat with us on irc.mozilla.org #jetpack
report a bug
check out the source and contribute bug fixes, enhancements, or documentation

Blog of Metrics: Sampling Crash Volumes, Rates and Rarity for Socorro Samples

Saptarshi Guha — Tue, 21 Feb 2012 23:21:31 +0000

1 Introduction

The Socorro crash report accumulation pipeline does not process all the crash reports. Though every report is stored on disk, only 10% are processed and saved in HBase as JSON objects. Each crash report has a crash signature (Crash Report Signature or CRS for short). The relationship between crash reports and CRSs is many to one.

Consumers of the crash reports (engineers working on bugfixes, product managers to name a few) had concerns regarding the use of samples. For example, some asked if the 10% sampling is a viable sampling rate to accurately estimate the frequency of the CRSs and if not all of them, then how accurate are the top N most frequently observed crash report signatures? With FF’s usage running into the 100 millions, we can expect new CRSs to be coming in every day. Some are very rare (occurs for a small user base) and others more frequent. How many days can we expect to wait till we see 50% of all the CRS that come in (for a given version)?

To answer these questions, the #breakpad team processed every crash report for the week 03/22-29/2011 , post Firefox 4 release. This served as a full enumeration of the crash report data. The full enumeration contained 2.2MM crash reports belonging to 84,760 CRSs.

Primarily, the crash-stats dashboard lists the top 100 most frequent crashes by OS. Some questions,

How accurate are the sample estimates? Does the top 100 from a sample equal the top 100 from the full enumeration (population) and are the proportion estimates accurate?
Given estimates, can we provide something about their accuracy?
How many distinct crash types are there? Throttling is a random sample of incoming crash reports. If in a 10% sample, we observe ‘N’ CRSs, can we estimate how many there in the population i.e. how many haven’t we seen? Estimating the number of unique CRS is entirely different from estimating the proportions of the CRS.

Firefox Support Blog: Ask Toolbar is changing the Firefox add-on process

Verdi — Tue, 21 Feb 2012 22:11:20 +0000

Note: This is my personal opinion and is not meant to reflect Mozilla’s views.

We’ve done a lot of work to help Firefox users have control over their add-ons (for example, bug 596343 and follow-ups 693743 and 693698) but some software companies are hard at work circumnavigating these protections. A while ago I filed bug 721258 concerned about the way the Ask Toolbar changes our 3rd party add-on confirmation screen. Today, in a follow-up comment I posted this screencast which shows an example of it in action:

Download video: MP4 format | WebM format

Some suggested that this isn’t that bad or that it could be worse. As someone charged with looking out for our users it’s pretty frustrating to run into that kind of opposition – just take a look at our support forum. Ask is known for this kind of stuff. And in fact, “how do I uninstall the Ask toolbar” is their top support question. It looks like we can’t do anything technical to prevent this at the moment. Maybe by drawing attention to it we can come up with another solution that protects people.

Jan — Tue, 21 Feb 2012 22:00:59 +0000

Hey Mozillians,

We’re back again with a new and interesting blog post. Today, we are going to answer some questions that might’ve popped into your head when you first saw our community’s website.

So, what’s this community?

We launched the community on February 7th and we want to share news, updates and other cool stuff from Antarctica with other Mozillians and interested people. The community consists of the blog, but we’re planning to add a forum in the future. We also have several goals that we’d like to tell you about:

Protecting the internet

ACTA, SOPA, PIPA, Hadopi,… All of these laws aim to stop the internet’s openness, which we are fighting for. It needs to be more and more commonly acknowledged that the internet’s openness needs be protected. We need an open internet to develop things like Mozilla, Linux, all the free and open-source software, techy communities, and even more. These programs were all possible because the internet was always open in the past.

Mitchell Baker, Chair of the Mozilla Foundation said in a blog post that ACTA would be a Bad Way to Develop Internet Policy. And in our opinion, she’s right.

In an interesting comment you could read this:

“Patent, Copyright and Trade Mark law is already complex enough to navigate and difficult to enforce…
We have moved beyond the information age and are now building new civilizations and communities online. The opportunity is to approach Internet regulation as we have done in some of our best moments: UN, UNESCO, Red Cross, etc.
I am reminded that when explorers and scientists opened up the frontier of Antarctica, the World signed a treaty gifting the continent to all of us. Now all countries comply with the Antarctic Treaty, which places scientific endeavor and protection of the environment before commercial gain. No country may place military bases in Antarctica and although rich in oil and minerals, it remains protected from commercial exploitation.
Similar ideals could apply to our digital frontier, but unfortunately it came into being because of its commercial possibilities. This doesn’t have to stop us though. Unlike a country, we are able to shape the digital world ourselves.
If you want to stop copyright infringements on the Internet, code safety measures, and don’t create laws, that prevent users from stealing intellectual properties. Virus filled files would then be left well alone on illegal torrent sites.”

How can I protect the Internet?

There are many campaigns that you can join. Luckily, on January the 20th, the Congress shelved the bills indefinitely. But there’s still the Anti-Counterfeiting Trade Agreement (ACTA) in Europe. You can for example sign an e-petition for an immediate stop of the negotiations. The agreement aims to establish an international legal framework for copyright infringement on the Internet, and would create a new governing body outside existing forums, such as the World Trade Organization, the World Intellectual Property Organization, or the United Nations. The problem is that it threatens many web services like YouTube, Google, Twitter or Facebook.

Okay, enough about that. Let’s talk about Antarctica now!

Why do we need more protection for this Ice-Land?

Today, thanks to the Antarctica Treaty System, Antarctica is declared as a land for peace and science. We’re happy that this treaty has no end for now. And thanks to the Madrid protocol, the environment of Antarctica is protected, which means that mining or exploiting natural resources for commercial purposes is strictly forbidden.
But unfortunately, this could end in 2048.
According to the Antarctica Treaty Secretariat:

“The Russian Federation introduced WP 55 On a strategy for the development of the Russian Federation activities in the Antarctic for the period until 2020 and longer-term perspective. The Russian Federation noted that its activities are designed, among other objectives, to strengthen the economic capacity of the Russian Federation by enhanced use of the marine biological resources of the Southern Ocean and complex investigations of Antarctic mineral, hydrocarbon and other natural resources. It clarified that these investigations would be purely scientific and consistent with the statement it made at ATCM XXV (Warsaw) on exploratory research, and would not contravene Article 7 of the Environment Protocol.”

This might be the beginning of exploitation of a Treaty/Protocol vulnerability. Under the cover of science, the Russian government is beginning to evaluate Antarctica’s resources.

But it won’t be the first time that a government is using this method: Under the cover of science, Japanese people are fishing whales in the southern ocean. Just have a look on the Sea Shepherd website.

Is this right?

We don’t think so! We are aiming to fight against this form of closure, but we need your help.

What should we do?

We are Mozillians and we believe in openness and peace. We will put our time and effort in order to protect the Antarctica environment, but because we also believe in open and accessible internet, we put our time and effort in protecting the internet that we all love.

There are two simple ways to show your love to Antarctica.

Taking Antarctica Treaty System as an example, we believe that we can, together, write laws for an open and accessible internet. It’s only seven pages to declare Antarctica as a land of peace and science. Antarctica is not the only place where ideals are possible. United Nation is also a major actor in human ideals. You can find all the treaty and protocol written by UN here. Feel free to also join campaigns or projects that want to protect this wonderful continent.
As the open internet and peaceful Antarctica probably both matter to you, please send us a photo of you and the Mozilla Antarctica logo, no matter if you went to Antarctica or not. You can also use it as a flag and put it in front of something Antarctica-related. Just because you support two symbols of freedom put together. We have already received lots of nice pictures. Here are some of them:

You can also join our Google group.

Apart from that, we have many exciting things that we want to share with you during the next few days and weeks. On our Facebook page, we announced a website which will allow you to send virtual postcards with your custom picture to your friends. And we’re also going to post an exciting interview with an Antarctican later this week, so stay tuned!

Remember, this is a community that is open for everyone who’s interested in Mozilla, Firefox or Antarctica. There are no limits, borders, or special requirements. In the beginning, it was a little dream that turned into something more and more important. A rising amount of scientists and Mozillians are getting interested in this project. Let us begin this great adventure and join us!

Mozilla IT: Caching for Monitoring: Timing is Everything

Sheeri — Tue, 21 Feb 2012 20:33:48 +0000

I found Baron’s reasoning on why the Percona Nagios plugins do not use caching interesting. On the surface, the logic is sound – you do not want to cache when you want real-time monitoring.

I have not yet had time to look at the Percona plugins for Nagios, though I do want to, because back at PalominoDB I helped write a Nagios plugin for MySQL that allows you to do arbitrary calculations. By “arbitrary calculations” I mean you can have a calculation like “Threads_connected/max_connections*100″ and set a threshold of “>80″. You can mix and match MySQL status variables and system variables, and use any perl functions as well, including basic arithmetic.

We put a caching function in there, complete with examples. Why would we do that if caching is bad, as Baron says? Well, long-term caching is bad, but it is certainly acceptable to have caching with a threshold lower than the check interval. With the PalominoDB Nagios plugin for MySQL, you can have 10 different calculations, and set the cache threshold on a per-check basis – the examples use 60 seconds.

If I have 10 calculations, I can set it so the checks do not re-connect to MySQL if there is a file that’s less than 60 seconds old. With checks that run every 5 minutes by default, it makes complete sense to cache the first run of SHOW STATUS/SHOW VARIABLES/SHOW PROCESSLIST, and the other 9 checks use the cache file – but only if it fresh within the past minute.

It is quite likely that the Percona Nagios plugins for MySQL do not lend themselves to this type of caching. Because the PalominoDB Nagios plugin is so powerful, it makes sense to have this type of micro-caching. Otherwise, each additional monitoring check adds more strain on the database.

Edited to add: I just took a look at the Percona monitoring plugins for Nagios and they check very, very different things. The level of customization is not as flexible as it is with the PalominoDB Nagios plugin, because it is checking very different things. The Percona monitoring plugins are a set of 12 different checks, as opposed to the 1 check that the PalominoDB plugin has. Still, I could see a value in caching the output of SHOW ENGINE INNODB STATUS (or whatever it uses) for the pmp-check-mysql-innodb plugin, so you can run it three times – once with the idle_blocker_duration option, once with the waiter_count option, and once with the max_duration option, and it only runs the command needed once.

Basically it comes down to this: Baron is correct when he says “Running SHOW STATUS infrequently doesn’t add load to the server.” and I am correct when I say “Running SHOW STATUS frequently adds a lot of load to the server.” The Percona plugin and the PalominoDB plugin are completely different, and there seems to be very little overlap.

Software Carpentry: Assessment Redux

Greg Wilson — Tue, 21 Feb 2012 19:23:47 +0000

The single biggest challenge Software Carpentry faces right now is how to tell what impact it’s having. This is only partly to satisfy funders—as I said back in December, if we don’t know how to tell if we succeeded, we’re going to fail. It would be (relatively) easy to put together a multiple-choice quiz to see how much people have learned about basic shell commands, the syntax of Python, and so on, but that would only address the shallowest aspects of learning. We’re trying to impart some fundamental principles, and what we need is questions that will tell us whether people have internalized them. (As many studies have shown, it’s possible to get a decent score on a quiz without actually understanding the subject matter.)

For example, consider this question about Subversion:

Emmy wants to see what has changed in her working copy since revision 120. The command she should run is:

svn log -r 120

svn diff -r 120

svn revert -r 120

None of the above

It addresses Q05 (“How can I keep track of what I’ve done?”) fairly directly, but not R02 (“Use a version control system”), R03 (“Automate repetitive tasks”), or any of the basic principles. Open-ended answers might do the latter, but it’s hard to come up with ones that don’t lead the witness: asking, “When would you use a version control system?” isn’t going to give us much insight into what people actually think. We could combine a few multiple-choice with a few open-ended, but realistically, if it takes more than 10-15 minutes for people to answer, many (most?) won’t. If anyone can see a way to square this circle, I’d welcome ideas.

Web FWD: Early Stage Financing: It's Complicated

Tue, 21 Feb 2012 17:21:12 +0000

Given all the buzz about angel and seed financing, it’s tempting to think these are easy choices. It’s a good thing we have experts to guide us!

Today our WebFWD Fellows heard the 2nd in a 3-part series for startups by our friends at Orrick, Herrington & Sutcliffe LLP, a firm very engaged with startups, particularly through its Total Access program. Orrick Partner Larry Kane walked us through various terms that entrepreneurs should consider when raising early rounds of funds.

For example, early rounds can often be raised as convertible notes (debt) rather than seed rounds (equity), and there are pros & cons to either choice. Debt has less legal costs and avoids issues of valuations, but remains on the balance sheet. It was good to learn that seed rounds are not just earlier versions of Series A rounds, but carry fewer disclosure requirements, as just one point of difference.

Overall, Larry was a wealth of information on conversions from one security to another, interest rates, risks and more. Highly recommended viewing!

Software Carpentry: Why Not Use Python

Greg Wilson — Tue, 21 Feb 2012 11:30:55 +0000

When we started Software Carpentry back in the late 1990s, we used Perl as a teaching language instead of Python. At the time, it was a no-brainer: Perl had many more users, better documentation, and more libraries. We switched because we found ourselves explaining the same inconsistencies over and over again (as I’ve said many times since, every page of the O’Reilly Pocket Guide to Perl used one of the words “except”, “unless”, or “however” at least once). Python had fewer “buts”: we saw right away that students were learning concepts more quickly, and they seemed to retain more as well.

But Python isn’t perfect, and I was reminded very forcefully of its biggest flaw on Saturday, when I spent half a day teaching kids aged 8-14 how to program as part of a Mozilla Hack Jam in Toronto. About three quarters of the kids were able to start drawing pictures with Python’s turtle graphics library right away. The other quarter, though, stumbled (and were sometimes blocked completely) by the same old installation headaches that plague grownups trying to use Python to do science.

One would-be learner showed up with a brand-new MacBook Air running OS X 10.7. Half an hour and four downloads later, he still couldn’t get a turtle to draw a straight line. We tried 32 and 64-bit DMGs for Python 2.7.2 and Python 3.2.2, without luck; the only advice Google found for us started, “Install the latest version of XCode…”, at which point we gave up. Several others, who had Windows 7 machines, were able to install, but then we discovered that Python still doesn’t put itself on the search PATH. “Oh,” said one of my helpers, “That’s easy, you just go into System… then Advanced… then edit this environment variable…” It’s a good thing he was looking at the computer as he said this, instead of at the faces of the kids he was trying to help—if he’d been doing the latter, he would have realized how inappropriate “simple” and “just” were.

People used to talk about “grand challenges” in scientific computing. Mostly, they meant the kind of big science that shows up on magazine covers. For me, though, the only “grand challenge” in scientific computing that matters is making stuff work the first time for everyone. It might not be as sexy as protein folding, global climate change, or predictive models of fender crumpling, but it would help a lot more people—and not just scientists.

Later: another stumbling block when doing things with turtle graphics is Python’s “counted loop” idiom:

for i in range(3):
  do something

If I want people to draw squares, hexagons, and what-not, I either wave my hands (“Trust me, this is just what you do”) or explain functions and lists when what I really want to do is explain loops. It’s not as big a thing as the installation headaches, but first-class ranges:

for i in [0:3]:
  do something

would make things noticeably easier in this one particular case. Is it important enough to merit changing the language? Probably not on its own, but if there are other reasons to do it—or to go all out and add a cross-product operator:

for (i, j) in [0:3] @ [0:5]:
  do something 15

As a bonus, we could then overload @ for matrix multiplication

Software Carpentry: Hello from Trieste!

Tommy Guy — Tue, 21 Feb 2012 09:57:47 +0000

Day 1 of the Trieste bootcamp was a success! Katy and I covered the Bash shell and git. It was encouraging to see students in the lab after dinner working on their shell exercises. In general, the students are very enthusiastic. Later we’ll try to list their home countries. So far, I’ve met people from Colombia, Mexico, Argentina, South Africa, Cameroon, Nigeria, Romania, Italy, Pakistan, Iran, India, and China. Their fields range from astronomy to nuclear physics to climate science.

Today, we are starting Python. You can follow our material on our github page’s wiki. Pay particular attention to Katy’s lectures on git and github, where she introduced git for personal use in hour one then introduced collaborative use through github in the second hour.

Here’s a picture (more to come!)

hacks.mozilla.org: Saving images and files in localStorage

Robert Nyman — Tue, 21 Feb 2012 09:36:14 +0000

As you might know, localStorage is quite powerful when it comes to quickly storing information in the user’s web browser, and it has also been around in all web browsers a long time. But how do we store files in it?

Using JSON for powerful control

Let’s start with some basic information about localStorage. When storing information in localStorage, you use key/value pairs, like this:

localStorage.setItem("name", "Robert");

And to read it out, you just get the value of that key:

localStorage.getItem("name");

That’s all good and well, and being able to save at least 5 MB, you have a lot of options. But since localStorage is just string-based, saving a long string with no form of structure isn’t optimal.
Therefore, we can utilize the native JSON support in web browsers to turn JavaScript objects to string for saving, and back into objects when reading:

Storing images

The idea here is to be able to take an image that has been loaded into the current web page and store it into localStorage. As we established above, localStorage only supports strings, so what we need to do here is turn the image into a Data URL. One way to do this for an image, is to load into a canvas element. Then, with a canvas, you can read out the current visual representation in a canvas as a Data URL.

Let’s look at this example where we have an image in the document with an id of “elephant”:

Then, if we want to take it further, we can utilize a JavaScript object and do a date check with localStorage. In this example, we load the image from the server through JavaScript the first time, but for every page load after that, we read the saved image from localStorage instead:

HTML

JavaScript

Note: A word of warning here is that you might exceed the size available in localStorage, and the best way to control that is using try...catch.

Storing any kind of file

So thats great, we can use canvas to turn images into Data URL and save in localStorage. But what if we want a mechanism that works for any kind of file?

Then it becomes a bit interesting, and we will need to use:

The basic approach is:

Do an XMLHttpRequest for a file, and set the responseType to “arraybuffer”
Load the response of the XMLHttpRequest into a BlobBuilder
Get the blob, i.e. file contents
Use FileReader to read that file and load it into the page and/or localStorage

Let’s look at a complete example where we request an image named “rhino.png”, save it onto a blob, use FileReader to read out the file and finally save that in localStorage:

Using “blob” as responseType

In the above example we used the responseType “arraybuffer” and a BlobBuilder to create something we could use for the FileReader. However, there’s also a responseType called “blob” which returns a blob directly that we can use with the FileReader. The above example would instead look like this then:

Web browser support

localStorage: Supported since long in all major web browsers, including IE8.
Native JSON support: Same long support as localStorage.
canvas element: Supported a long in most major web browsers, but only since IE9.
XMLHttpRequest Level 2: Supported in Firefox and Google Chrome since long, Safari 5+ and planned to be in IE10 and Opera 12.
BlobBuilder: Supported in Firefox and Google Chrome since long, and is planned to be in IE10. Unclear about Safari and Opera.
FileReader: Supported in Firefox and Google Chrome since long, Opera since 11.1 and is planned to be in IE10. Unclear about Safari.
responseType “blob”: Currently only supported in Firefox. Will soon be in Google Chrome and is planned to be in IE10. Unclear about Safari and Opera.

Checking and clearing localStorage

The easiest way to check what’s in localStorage:

Firebug: DOM tab, then scroll down to or search for localStorage
Google Chrome: Developer Tools, under the Resources tab
Opera: In the Storage tab in Opera Dragonfly

Demo and code

I’ve put together a demo with localStorage and saving images and files in it where you can see both the canvas approach and the one using XMLHtpRequest 2, BlobBuilder and FileReader.

The code for storing files in localStorage is also available on GitHub, so go play now!

European Mozilla Community Blog: About Mozilla Spaces...

Julia — Mon, 20 Feb 2012 14:23:00 +0000

When I attended the Mozilla Festival last November, I saw an unusual workshop: you had to "hack" a space to make it the ideal place to work, create, innovate, in short, change the world. Initially, you had a plan of an empty space and add parts, equipment, furniture, arrange it to fit your needs. It was then possible to create the office of our dreams with modeling clay. The final step was to share plans, to create a debate around what should be a workspace. The project was called "Hack-A-Space".http://www.mozilla.org/en/about/mozilla-spaces/ Recently, Mozilla launched a web page named Mozilla Spaces:

Mozilla Spaces are open working environments where Mozillians can hack, code, design, research, create, engage and contribute to building a brighter future for the Web. Keep reading to learn more or check out the map above for info on specific locations.

And I don't know why, but this project remind me about the Mozilla Festival's workshop. As this workshop suggested, I share my version of Mozilla Space "hacked", in Paris' sauce, of course

In downtown, close from a metro station: it must be conveniently accessible.
Unlimited Internet, high availability, unfiltered, uncensored: it sounds trivial, but nothing more irritating than a cut Internet during a meeting or when you're researching for a project. Similarly, nothing more boring than blocked ports when we want access to Jabber to contact people, for example.
Comfortable desks, in relatively large quantities, in a calm environment: it sounds trivial again, but nothing more annoying than a creaky chair or an unsteady desk. Small offices isolated must be added, where it may be possible to isolate themselves to think or to phone.
A conference room: to make events more or less public, conferences, demos, lessons, playing geeks in short.
A kitchen and a relaxation area: we all know the coffee machine's phenomenon that solves bugs, or at least is useful to disconnect and socialize 5 min.
Accessibility to all: triviality again, but nobody thinks about it. In the same way that web integrators often forget the integration of accessibility, we often forget that a work place must be accessible for a wheelchair.
An on-line forum, dedicated to the Space: to keep in touch afterwards, there is no better way than the Web. For keeping exchanges about past events, announcing next ones, requesting emergency assistance, etc. A instant channel and a recording one is the perfect combo (for example, IRC + wiki).
A community manager: to organize life in this kind of place, an office manager is not enough. It needs someone close to communities, capable of directing newcomers, organizing events (geek or not geek), speaking for Mozilla, linking projects to the Space.

Imagine that this co-working space dedicated to the Web is available in Paris! Just a quick scenario. I am bringing a project. It may be an association project, an software's idea, even a project to create a business, why not? I'm home alone, and do not necessarily like to work at my place. Also, I did not necessarily have all the skills for my project. I seek a place where I'm pretty sure of finding people to help me, or even to take part in the project, if it tells them. I see this kind of spaces, where meetings are organized about documentation, code, open web, standards, [add your topic here] are organized.

A beautiful dream of geek, isn't it?

Mozilla Security: Message to Certificate Authorities about Subordinate CAs

Johnathan Nightingale — Sat, 18 Feb 2012 04:36:27 +0000

Earlier today we sent an email to all certificate authorities in the Mozilla root program to clarify our expectations around certificate issuance. In particular, we made it clear that the issuance of subordinate CA certificates for the purposes of SSL man-in-the-middle interception or traffic management is unacceptable. We made it clear that this practice remains unacceptable even when the intended deployment of such a certificate is restricted to a closed network.

In addition to this clarification, we have made several requests. We have requested that any such certificates be revoked, and their HSMs destroyed. We have requested the serial numbers of those certificates and fingerprints of their signing roots so that we, and other relying parties, can detect and distrust these subCA certificates if encountered. We have requested that any CAs who have issued subCA certificates fulfill these requests no later than April 27, 2012.

Finally, we re-iterated our belief that each root is ultimately accountable for every certificate it signs, directly or through its subordinates. Participation in Mozilla’s root program is at our sole discretion, and we will take whatever steps are necessary to keep our users safe, up to and including the removal of root certificates that mis-issue, as well as any roots that cross-sign them. Nevertheless, we believe that security is best served when browsers and CAs can work together; we hope that frank communication and clear expectations can resolve these issues before any such action is required. We must also be diligent in looking for new ways to improve the security systems of the web. Those systems are built on the trust of web users, and we all have a responsibility to be strong stewards of that trust.

Mozilla Security: Mozilla releases to address CVE-2011-3026

Daniel Veditz — Fri, 17 Feb 2012 16:18:58 +0000

Issue

The libpng graphics library, used by Firefox and Thunderbird as well as many other software packages, contains an exploitable integer overflow bug. An attacker could craft malicious images which exploit this bug, and deliver them to users through websites or email messages.

Impact to users

This bug is remotely exploitable and can lead to arbitrary code execution. Firefox, Thunderbird and Seamonkey users could be attacked simply by displaying a maliciously crafted image.

Status

Mozilla is aware of this bug and has issued a fix that will be released today for Firefox and Thunderbird.

The bug was reported by RedHat representatives

Mozilla IT: This week in Mozilla Databases: Friday February 17, 2012

Sheeri — Fri, 17 Feb 2012 15:49:49 +0000

I have been at Mozilla nearly three months, and I used to blog a lot more than I currently do. A lot of the content I used to blog about I end up blogging and talking about in OurSQL: The MySQL Database Community Podcast. And I have also been getting used to the Mozilla firehose, as well as my own firehose of database projects that need to be done.

There are two very large projects that are time-sensitive that I am working on: migrating databases from an older data center to a newer one, and the impending public launch of the Mozilla Apps Store.

That being said, this week in Mozilla databases we have:

- migrated/improved/built our dev/stage databases for Socorro, our crash stats database.

- put monitoring on a newer backup server, after a random check showed replication had been stopped on one backup instance for several days due to the master’s binary logs changing names. Of course we also fixed that broken replication.

- made more progress getting the newer backup server to act like the older backup server – we do physical and logical backups, and currently the logical backups are working properly. The physical backups are a legacy cold backup, and I will not be migrating that, instead opting to use xtrabackup.

- turned off our Scalarc software, as we now have an appliance for our proof-of-concept test.

- retired 2 machines that were not in use, and exist in our older data center. I am always paranoid when I shut a machine down, triple-checking that I am on the right server when I type “shutdown now”.

- did a test migration of the production database for Mozilla QA, from the old data center to the new one.

- added new custom fields to Bugzilla for the release of Thunderbird 10.

- Created new databases and access for:
– Case Conductor, a replacement for Litmus for the QA team
– De Todos Para Todos, Mozilla’s outreach project to Latin America.

There is much much more to come in the weeks ahead!

BlueGriffon: One-Click Templates Manager 2.0

BlueGriffon — Fri, 17 Feb 2012 13:19:00 +0000

I'm currently ironing the v2.0 of our One-Click Templates add-on to BlueGriffon. First version of that add-on is already a best-seller and I think you're going to like v2.0. Main changes are:

nearly 3,000 (yes, three thousand) free HTML+CSS templates!
you can now create your own One-Click Templates from any document of yours

So here's a static demo for you, click on the images to see a larger version.

First let's have a web document created inside BlueGriffon. For instance a blank page for the BlueGriffon web site:

We are going to turn that document - and all the objects linked to it (stylesheets, replaced elements, fonts) - into a personal template through the File > Save as Template menu entry:

The dialog it opens offers first to select where you want your templates and the associated database to be stored, and then set a few metadata for your template (mandatory unique name, description, license):

Once all choices are made, the dialog looks like:

And we only have to click on the Save button to create our template's package. Once it's done, the package's file is revealed by the OS. Please note the sqlite database for easier access to templates' metadata. All URLs inside our document or inside the associated stylesheets (including imported stylesheets, whatever the nesting level) are rewritten for cleaner packaging.

Now let's close our original document and use our new personal template. To do that, use the File > One-Click Templates menu entry

That opens the Template Manager. In the current version, 2864 free templates are available!

Just for fun, let's look at the templates proposed under Creative Commons Attribution 2.5 by freecsstemplates.org:

For each template, we have a thumbnail, a description if one is available, a license, an author, a button linking to a live demo if one is available and a button to select that template to create a new document. If a large preview image is available, clicking on the thumbnail will show it. Hitting the Select button to use the template requires only one last operation from you: you must provide a file name for your new document... Let's go back now to our personal templates, and here's the one we just created:

So let's create a new document based on our personal template. As I said earlier, I only have to provide a file name:

I'm all set. My new document is here. Wherever were the original files on my hard disk, I now have a "blank" document based on a template well packaged, all media files living together, all stylesheets living together, all fonts living together, all scripts living together for a greater maintainability.

Every time you'll use the File > Save as Template menu entry, it will remind you the location of the directory where your personal templates live in. Backing them up is then trivial and giving them to someone else is also trivial. Just give that person a copy of your templates directory...

This v2.0 is going live soon, don't miss it!

Update: images updated so they don't harm planet.mozilla.org

Tenir un stand pendant un événement vous ennuie ? Bonjour Mozilla a la solution, en la personne de Otto de Voogd ! Avoir Otto dans son équipe, c’est la garantie de pouvoir toucher le grand public tout en passant vous-même un bon moment ! Car Otto est un trésor d’humour et de gentillesse, le meilleur des ambassadeurs : il sait parler à chacun, l’apostrophant d’un “bonjour” dans toutes les langues (car Otto parle anglais, néerlandais, et français), est toujours disponible, et se révèle un excellent camarade. Né en Hollande, Otto vit aujourd’hui en Estonie… Et il en est fier ! Car ce pays résiste vaillamment au traité ACTA, et se montre à la pointe en matière de libertés sur Internet. Libriste convaincu, Otto contribue depuis longtemps à Mozilla, il développe notamment des outils pour Firefox, dont le célèbre et indispensable Foxysearch.

Bonjour Otto, et merci pour tout ce que tu as fait au Fosdem !

Keeping a booth at an event get you bored? Bonjour Mozilla has the solution in the person of Otto de Voogd! Having Otto in your team guarantees you to reach the general public while having a good time! Since Otto is overwhelming with humor and kindness, he is the best ambassadors: he can speak to everyone starting the conversation with “hello” in every language (since Otto speaks English, Dutch, and French), is always available, and is a very good fellow. Born in Holland, Otto now lives in Estonia… and is proud of his adoptive country for its valiant resistance to the ACTA treaty, and its being on the edge of Internet freedom matters. Free Software advocate, Otto is a longtime Mozilla contributer and has developed tools for Firefox among which the famous and indispensable Foxysearch.

Bonjour Otto, and thank you for everything you did at Fosdem!

Mozilla Add-ons Blog: Using Javascript ( *.jsm ) modules in the SDK

Jeff Griffiths — Fri, 17 Feb 2012 00:33:06 +0000

The ability of developers using the SDK to get chrome authority and access xpcom services is a key feature. The SDK was designed from the start with the assumption that some developers will always need access to the underlying Mozilla platform. While xpcom is the main way to access low level apis, a lot of functionality in Firefox is instead implemented as JavaScript Modules, and can be used in your code much more naturally than xpcom services because they are just JavaScript, and from a design perspective quite similar to CommonJS modules.

Here’s a code snippet that you can use to import a jsm into your code:

const { Cu } = require("chrome");
 
let AddonManager = Cu.import("resource://gre/modules/AddonManager.jsm").AddonManager;
 
AddonManager.getAddonsByTypes(["extension"], function(addons) {
    var addonData = [];
 
    for (let i in addons) {
		let cur = addons[i];
		addonData.push({
			id: cur.id.toString(),
			name: cur.name,
		});
	};
	console.log(JSON.stringify(addonData, null, '   '));
});

The code requires chrome in order to get the Cu object ( Components.Utils ) and then imports the AddonManager module. Nice and easy! The only real problem with adding code like this to your add-on is that getting chrome authority to access Cu has review implications on AMO, and we in the Jetpack team want to do everything we can to get your add-ons reviewed as quickly as possible.

With that in mind, we have been considering including a utility function in the SDK that allows developers to import jsm modules without having to get chrome authority. Ben Buksch contributed this code snippet in a bug that neatly abstracts the small amount of chrome-level code into a single function:

const { Cu } = require("chrome");
/**
 * Imports a JS Module using Components.utils.import()
 * and returns the scope, similar to Jetpack require().
 *
 * @param targetScope {Object} (optional)
 *     If null, the scope will just be returned
 *     and *not* added to the global scope.
 *     If given, all functions/objects from the JSM will be
 *     imported directly in |targetScope|, so that you
 *     can do e.g.
 *       requireJSM("url", this)
 *       someFuncFromJSM();
 *     which will have the same effect as
 *       Components.utils.import("url");
 *       someFuncFromJSM();
 *     in normal Mozilla code, but the latter won't work in Jetpack code.
 */
function requireJSM(url, targetScope)
{
  var scope = targetScope ? targetScope : {};
  return Cu.import(url, scope);
  return scope;
}

I’ve created a Jetpack module on Builder that you can use to load Javascript modules using Ben’s code:

https://builder.addons.mozilla.org/library/1040049/latest

I’ve also created this example addon that uses my module:

https://builder.addons.mozilla.org/addon/1040048/latest/

Here is the above code, re-factored to use my module:

 
let requireJSM = require("jsmutils/jsmutils").requireJSM;
let AddonManager = requireJSM("resource://gre/modules/AddonManager.jsm").AddonManager;
 
AddonManager.getAddonsByTypes(["extension"], function(addons) {
	var addonData = [];
 
	for (let i in addons) {
		let cur = addons[i];
		addonData.push({
			id: cur.id.toString(),
			name: cur.name,
		});
	};
	console.log(JSON.stringify(addonData, null, '   '));
});

I know what you’re thinking – there isn’t really any less code involved using the abstracted module. I would argue that the advantage is instead that I have isolated the part of my code that needs chrome authority to a single, small file that is very easy to understand. This is better separation and greatly aids the ability of our add-on reviewers to quickly understand your code and any security implications it might have.

Mozilla Add-ons Blog: The Add-on Review Queues are empty!

Jorge Villalobos — Thu, 16 Feb 2012 23:56:48 +0000

Thanks to the tireless efforts of the AMO Editors group, we have reached an important milestone that hasn’t been reached in years (or ever, probably). All add-on review queues are currently empty.

This means that if you submit your add-on now or in the following days, chances are it will be reviewed within a few minutes. This is amazing feat, specially considering that add-on submissions are constantly increasing, and we add new policies all the time that make add-on reviews higher quality, but also longer to perform.

We’d like to thank and congratulate the AMO Editors team for their exceptional work along the years. You guys are amazing! We’ll call out our most active contributors soon, when we wrap up the very successful New Year’s Challenge.

PS: If you’re an add-on developer and your add-on hasn’t been reviewed, please get in touch with us by commenting here. It’s possible that your add-on is in an Incomplete state and you forgot to add it to one of the queues, or it could be a bug on our site.

Identity at Mozilla: BrowserID now available in 28 languages

Thu, 16 Feb 2012 21:49:12 +0000

We’re proud to announce that with the latest update to BrowserID the sign-in flow is available in 28 languages, in addition to English.

Like many of our previous updates, users and sites automatically benefit from the added feature without having to change anything. Users will see BrowserID in their preferred language, based on their browser’s settings.

Here’s what BrowserID looks like in traditional Chinese:

This change has been possible because of our amazing community of volunteers. Firefox ships in over 70 languages and that energy also powers our vision for a cross-platform identity management.

Along with ID provider support, shipping our service in multiple languages are two big milestones for BrowserID maturity.

Users of your websites can now have a native language experience in the following locales:

Afrikaans (af)	català (ca)	Čeština (cs)	Dansk (da)
Deutsch (de)	Ελληνικά (el)	Español (es)	Eesti keel (et)
Euskara (eu)	suomi (fi)	Français (fr)	Frysk (fy)
Gaeilge (ga)	Hrvatski (hr)	Italiano (it)	Ligurian (lij)
Nederlands (nl)	ਪੰਜਾਬੀ (pa)	Polski (pl)	Русский (ru)
slovenčina (sk)	slovenščina (sl)	Shqip (sq)	Српски (sr)

Software Carpentry: How They See Us, Part N

Greg Wilson — Thu, 16 Feb 2012 17:08:10 +0000

This week’s Ed-Tech Podcast from Steve Hargadon and Audrey Watters discusses Software Carpentry a bit around the 23:00 mark [1]. In answer to Hargadon’s point about home schooling, and whether the way people learning programming even fits the notion of class, we have a couple of answers. First, most of the people we’re trying to help don’t know enough (yet) to know what to type into Google, how to recognize when they’ve stumbled upon an answer to their problem, or what to tag a question with on Stack Overflow. Some can climb that hill themselves; a handful can’t, but most won’t (see below), so one of our goals is to help them get from A to B so that they can get from B to Z.

In addition, while the scientists and engineers we’re trying to help might think that computing is interesting, their real passion is quantum chemistry, neurology, or climate change; in practical terms, computing is a tax they have to pay in order to do the research they actually want to do [2]. From that perspective, “wander around and stumble upon” feels like a high-risk strategy, so they (mostly) vote with their feet and don’t do it.

Second, even those who do wander and stumble tend to find very different things. As a result, there’s no common core of skills or assumptions that one researcher can reasonably expect her peers to be familiar with. In contrast, most researchers can expect colleagues to know at least a few basic things about statistics, and to share some cultural values about when a correlation is significant and so on. In choosing what to include in our core, we’re also (implicitly) making a statement about what that core is, and what’s reasonable to expect others to share.

[1] What’s really interesting, though, is the discussion in the first few minutes about Silicon Valley’s ed-tech amnesia.

[2] Regarding Hargadon’s comment about “willingness to hack”, I think that every researcher I’ve ever met has that in spades—they’re just investing that energy in something other than programming. And yes, lists of “things programmers need to know” make me yawn too—but only if I already know enough about the topic to forge ahead on my own. I’m really grateful for “must read” lists whenever I dive into a new area…

Major Topics for This Week

Release Roadmap: Fx 11 XUL is going to Beta channel. Fx 10 XUL ESR is going to the Release channel.
Uplift Situation: We are focusing on mozilla-central and less on constant uplift. Feel free to request “aurora” and “beta” approval for important bugs. We’ll be doing a mass uplift closer to merge of other things (not critical) that we want on Aurora and Beta.
Crashes: The crash statistics are improving, but we still need to keep a focus on cleaning them up.
Maple Status: Status update from the GFX team on what’s happening in Maple, what we can expect and when we can expect it.

Stand ups

Suggested format:

Kats

Last week:
- getting up to speed on new gl layers compositor
- did some instrumenting to get some metrics from the new compositor (time spent compositing, uploading textures, waiting)
- wrote a tool to visualize different viewports so we can quickly get an idea of whether our behaviour is correct
- did some instrumenting to compare skia vs cairo render times using a skia-enabled build on the galaxy nexus
- refactored a bunch of the profile-reading code in java so it’s cleaner and more efficient (bug 726382) and hopefully allows 723295 to land without triggering random failures
- got more tests running on the maple branch
- fixed up compiler warnings on java 1.7

Next week:
- more GL layers stuff – instrumenting and finding out where time is being spent, making sure tests are passing

UX & User Research

Market Insights

Desktop / Platform

Google

The Chromium team expanded the Chromium Security Rewards Program, by increasing its scope to cover the Chromium OS.
The new Chrome Beta release enables GPU-accelerated rendering of 2D canvas content, and also enables WebGL acceleration for people with older GPUs using Swiftshader, a software rasterizer that Google licensed from TransGaming. This should make for significant performance improvements on systems like Windows XP.
Chrome’s dev channel features an updated V8 Javascript engine that offers initial support for lexical scoping, collections, weak maps, and proxies.
Google also released a Field Guide to Web Applications that offer a high-level, architectural overview of how to design web applications. Their HTML5Rocks site was updated, and features an excellent detailed overview of the architecture of the Chrome and Mozilla browsers.
Chrome 17 stable was released. 20 security bugs were fixed — 1 critical, 8 high, 5 medium, and 6 low. A significant number were detected with AddressSanitizer, a fast memory error detector.
Chrome’s Dev Channel release has a few interesting new features, including using Google’s servers to conduct spellchecking for entered and pasted text.
The Sencha team conducted an initial review of Google Chrome for Android, giving it high marks. It notes that SunSpider performance is little different than other browsers and suggests that it is now time to shelve that particular benchmark test.

Opera

The latest snapshot of Opera 12 offers support for Do Not Track and a substantial number of SSL performance optimizations.

Microsoft

Microsoft released a Critical update for MSIE 6, 7, 8, and 9. The vulnerability would allow remote code execution from a specially constructed web page. The update itself had to be updated shortly afterwards after it incorrectly reported that google.com was infected with the Blackhole Exploitation Kit.
MSIE 10 will allow full support for Cross-Origin Resource Sharing for XMLHttpRequests.
In a 9,000 word blog post, Microsoft’s Windows president Steven Sinofsky divulged a slew of details on Windows on ARM. Microsoft plans to have ARM PCs available when other Windows 8 computers are available, and the company will also include desktop versions of optimized Office 15 applications. Windows 8 ARM PCs will also never turn off, instead going into a standby mode that should last for weeks.

WebOS

HP released the source code to Isis, the WebOS browser, which apparently offers “unrivaled speed and standards compliance”.

W3C

Webmonkey has a good summary article describing the issues and positions in the debate as to whether other browsers should support -webkit-prefixed CSS properties. (Also, Tantek’s interview at A List Apart.

Mobile

Software Carpentry: Watch Me: Volunteers Wanted

Greg Wilson — Wed, 15 Feb 2012 19:13:10 +0000

Back in 2007, Jon Udell observed that screencasts facilitate accidental knowledge transfer in a way that more traditional media don’t. As I said yesterday, we’d therefore like to start recording short screencasts of programmers thinking aloud as they solve small problems using their preferred tools. The aim is to show learners how to program—what order to write things in, how to debug, when and how much to test, and so on. Everything will be covered by the same Creative Commons license as our other material, and made freely available for remixing and other use.

If you’d like to help, please:

Volunteer to be recorded by mailing us. We’ll help you install a screen recorder (if you don’t have one already—you might be surprised to find that you do), give you a small problem, and edit the video you produce so that you don’t have to.
Volunteer to edit video for us, so that we can put our energy into organizing people .
Volunteer to work the floor at PyCon in March. We can’t attend (workshops to run, etc.), but it would be great if we could get a dozen or more “here’s how I do it” recordings done during the conference.

Remember, as an open source project, Software Carpentry depends on your help to survive and thrive. If you have wanted to help, but have worried that creating and recording lectures would be too much work, this is a way for you to help that will take half an hour or less. We look forward to hearing from you.

Software Carpentry: Analyzing Next-Generation Sequencing Data

Greg Wilson — Wed, 15 Feb 2012 18:17:16 +0000

Analyzing Next-Generation Sequencing Data

http://bioinformatics.msu.edu/ngs-summer-course-2012

June 4th – June 15th, 2012
Kellogg Biological Station, MSU
Course sponsor: NIH.

Instructors: Dr. C. Titus Brown, Dr. Ian Dworkin, and Dr. Istvan Albert.

Board of advisors: Dr. Kevin White; Dr. Paul Sternberg; Dr. Rich Lenski; Dr. Robin Buell; Dr. Jim Tiedje; Dr. Lincoln Stein

Applications are being accepted through March 1st (midnight Pacific)!

Course Description

This intensive two week summer course will introduce attendees with a strong biology background to the practice of analyzing short-read sequencing data from Roche 454, Illumina GA2, ABI SOLiD, Pacific Biosciences, and other next-gen platforms. The first week will introduce students to computational thinking and large-scale data analysis on UNIX platforms. The second week will focus on mapping, assembly, and analysis of short-read data for resequencing, ChIP-seq, and RNAseq.

No prior programming experience is required, although familiarity with some programming concepts is helpful, and bravery in the face of the unknown is necessary. 2 years or more of graduate school in a biological science is strongly suggested. Faculty, postdocs, and research staff are more than welcome!

Students will gain practical experience in:

Python and bash shell scripting
cloud computing/Amazon EC2
basic software installation on UNIX
installing and running maq, bowtie, and velvet
querying mappings and evaluating assemblies

Materials from last year’s course are available at http://ged.msu.edu/angus/tutorials-2011 under a Creative Commons/use+reuse license.

You can read a blog post about last year’s course at http://ivory.idyll.org/blog/jun-11/ngs-2011.

Software Carpentry: And Speaking of New…

…check out Bret Victor’s talk at CUSEC 2012—jump in around the 7:00 mark and watch for a couple of minutes. You’ll want to go back and watch the whole thing…

Software Carpentry: Slide Drive

Greg Wilson — Wed, 15 Feb 2012 16:30:30 +0000

Speaking of new kinds of content (which I’ve been doing a lot), David Seifreid has built a working prototype of a new slideshow tool that combines deck.js with an HTML5 audio player. You can check out a demo at http://software-carpentry.org/slide-drive/index.html, or grab the source from https://github.com/dseif/slide-drive. Slides are pure HTML like this:

<section popcorn-slideshow="24">
  <h2>Solution</h2>
  <p>Short intensive workshops</p>
  <div>
    Our solution combines short, intensive workshops...
  </div>
  <div popcorn-slideshow="27">
    <p>Plus self-paced online instruction</p>
    <div>
      ...with self-paced online instruction.
    </div>
  </div>
</section>

which combines slide pages and transcripts in a single file suitable for diffing and merging. (Images are still in external files, but I can live with that.) You can pause the slideshow at any point to select and copy the content (something you definitely can’t do with a video), and we’ll add support for translations into other languages and so on.

Many thanks to David for pulling this together; please let us know what you think.

Bonjour Mozilla: David McNamara (Mackers)

clarista — Wed, 15 Feb 2012 09:00:00 +0000

David McNamara (alias mackers) est un artiste, mais aussi un hacker, travaillant avec Brian King au sein de Briks Software, et contribuant à des projets Mozilla depuis… 2000 ! David est une sorte de vagabond des temps moderne, un “voyageur digital” qui n’a de cesse de découvrir le monde, multipliant les rencontres, et diffusant au passage la bonne parole du Logiciel Libre. Il est certes originaire de Dublin, en Irlande, mais vous aurez souvent plus de chances de rencontrer ce globe-trotter dans un autre pays, son MacBook sous le bras. C’est ainsi qu’il parvient, d’où qu’il soit, à créer des add-ons pour Briks, et même à poursuivre ses études ! Sans oublier, mais cela ne vous étonnera pas, sa passion pour la Geo-Web. En regardant plusieurs photos de lui, Bonjour Mozilla s’est aussi aperçu que David était un sacré boute-en-train, qui ne se prend pas au sérieux… Avec un collègue comme Brian King, on imagine les séances de brainstorming… Elles doivent être animées !

Bonjour David !

PS : et merci Brian King pour son aide !

David McNamara (aka mackers) is an artist, but also a hacker, working with Brian King at Briks Software, and contributing to Mozilla projects since… 2000! David is kind of a modern tramp, a “digital traveler” who is constantly discovering the world, multiplying meetings, and disseminating the good word of Free Software on his way. Although he is originally from Dublin, Ireland, you’re more likely to meet this globe-trotting in an other country, his MacBook under the arm. Thus he succeeds, wherever he is, to create add-ons for Briks, and even to continue his studies! Not to mention, you won’t be surprised, his passion for the Geo-Web. By looking at several pictures of him, Bonjour Mozilla has also noticed that David was a live wire which does not take itself seriously… With a colleague such as Brian King, we can only imagine the brainstorming sessions… They must be well alive!

Bonjour David!

PS: and thanks for the help, Brian King!
