Jet Villegas: Gaia Tips and Tricks for Gecko Hackers

di, 14/04/2015 - 02:28

I’m often assigned Firefox Rendering bugs in bugzilla. By the time a bug gets assigned to me, the reporter had usually exhausted other options and assumed (correctly) that I’m ultimately responsible for fixing Firefox rendering bugs. Of course, I often have to reassign most bugs to more capable individuals.

Some of the hardest bugs to assign are the ones reported by our own Gaia team: the team responsible for building the user experience in Firefox OS. The Gaia engineers take CSS and JavaScript and build powerful mobile apps like the phone dialer and SMS client. When they report bugs, it’s often found within lots of CSS and JS code. I wanted to learn how to effectively reduce the time it takes to resolve rendering issues reported by the Gaia team. It takes a long time to go from a Gaia bug like “scrolling in the gallery app is slow” to find the underlying Gecko bug, for example “rounding issue creates an invalidation rectangle that is too large.”

To do that, I became a Gaia developer for a few days at our Paris office. I reasoned that if I could learn how they work, then I can help my team boil down issues faster and become more responsive to their needs. We already recognize the value of having expert web application developers on staff, but we could do a better job with a better understanding of how they work. With that in mind, I spent the week without any C++ code to look at, and dived into the world of mobile web app development.

I wrote down the steps I took to set up a FirefoxOS build and test environment in an earlier post This time, I’ll list a few of the tips and tricks I learned while I was working with the Gaia developers.

The first and most important tip: You will brick the phone when working on the OS. In fact, you’re probably not trying hard enough if you don’t brick it :) Fastboot lets you connect ADB to the phone when it becomes unresponsive to flash the device with a known good system (like the base image.) Learn how to manually force fastboot on your phone.

Julien showed me how to maintain a Gaia developer profile on your desktop development environment. This set of commands will configure your B2G build to produce the desktop B2G runtime that’s a bit easier to debug than a device build:

# change value of the FIREFOX to point to the full path to the B2G desktop build export FIREFOX=/Volumes/firefoxos/B2G/build/dist/ export PROFILE_FOLDER=gaia-profile DEBUG=1 DESKTOP=0 make

With a Gaia developer profile, you can switch between B2G desktop and a regular Firefox browser build for testing:

export FIREFOX=/full/path/to/desktop/browser $FIREFOX -profile gaia-profile --no-remote app://

The Gaia profile lets you use URL’s like app:// to run the Gaia apps on the desktop browser. This trick alone was a huge time saver! Try it with other URL’s like app://

For a first Gaia development project, I picked up the implementation of new card view for gaia that is based on an asynchronous panning and zooming (APZC.) Etienne did the initial proof-of-concept and my goal is to rebase/finish/polish it and add some CSS Scroll Snapping features. My initial tests for this feature are very promising. CSS Scroll Snapping is much more responsive than the previous JavaScript-based implementation. I’m still working out some bugs but hope to land my first Gaia pull request soon.

I’ve already been able to apply what I’ve learned to triage bugs like this one. The bug started out described as a problem with how we launch GMail on B2G in Arabic language. Based on the testing tricks I learned from Gaia team, I was able to distill it to a root cause with scrollbar rendering on right-to-left (RTL) languages. I added a simplified test case to the bug that should greatly reduce debugging time, and assigned it to one of our RTL experts. That’s quite a bit better than assigning tough bugs to random developers with the entire OS as the test case!

Thanks to Julien and Ettiene for helping me get up to speed. I highly recommend that any Gecko engineer spend a few days as a Gaia hacker. I’m humbled by the ingenuity these developers have for building the entire OS user experience with only the capabilities offered by the Web. We could all learn a lot in the trenches with these hackers!

John O'Duinn: “why work doesnt happen at work” by Jason Fried on TEDx

di, 14/04/2015 - 02:20

While reading “Remote”, I accidentally found this TEDx talk by one of the authors, Jason Fried. Somehow I’d missed this when it first came out in 2010, so stopped to watch it. I’ve now watched this a few times in a row, found it just as relevant today as it was 4-5 years ago, so am writing this blogpost.

The main highlights for me were:

1) work, like sleep, needs solid uninterrupted time. However, most offices are designed to enable interrupts. Open plan layouts. Phones. Casual walk-by interrupts from managers asking for status. Unneeded meetings. They are not designed for uninterrupted focus time. No-one would intentionally plan to have frequently-interrupted-sleep every night and consider it “good”, so why set up our work environments like this?

2) Many people go into the office for the day, attempting to get a few hours uninterrupted work done, only to spend time reacting to interrupts all day, and then lament at the end of the day that “they didn’t get anything done”! Been there, lived through that. As a manager, he extols people to try things like “no-talking-Thursdays”, just to see if people can actually be more productive.

3) The “where do you go when you really want to get work done” part of his presentation nailed it for me. He’s been asking people this question for years, and the answers tend to fall into three categories:

  • place: “the kitchen”, “the spare room”, “the coffee shop”, …
  • moving object: plane, train, car… the commute
  • time: “somewhere really early or really late at night or on the weekend”

… and he noted that no-one said “the office during office hours”!! The common theme is that people use locations where they can focus, knowing they will not get interrupted. When I need to focus, I know this is true for me also.

All of which leads to his premise that organizing how people work together, with most communication done in a less interruptive way is really important for productivity. Anyone who has been at one of my remoties sessions knows I strongly believe this is true – especially for remoties! He also asked why businesses spend so much money on these counter-productive offices.

Aside: I found his “Facebook and twitter are the modern day smoke breaks” comment quite funny! Maybe thats just my sense of humor. Overall, its a short 15min talk, so instead of your next “facebook/twitter/smokebreak”, grab a coffee and watch this. You’ll be glad you did.

Nick Cameron: Contributing to Rust

ma, 13/04/2015 - 23:40
I wrote a few things about contributing to Rust. What with the imminent 1.0 release, now is a great time to learn more about Rust and contribute code, tests, or docs to Rust itself or a bunch of other exciting projects.

The main thing I wanted to do was make it easy to find issues to work on. I also stuck in a few links to various things that new contributors should find useful.

I hope it is useful, and feel free to ping me (nrc in #rust-internals) if you want more info.

Matt Thompson: Mozilla Learning Networks: what’s next?

ma, 13/04/2015 - 22:04

What has the Mozilla Learning Networks accomplished so far this year? What’s coming next in Q2? This post includes a slide presentation, analysis and interview with Mozilla’s Chris Lawrence, Michelle Thorne and Lainie DeCoursy. It’s a summary of a more detailed report on the quarter here. Join the discussion on #teachtheweb.

What’s the goal?

Establish Mozilla as the best place to teach and learn the web.

Not only the technical aspects of the open web — but also its culture, citizenship and collaborative ethos.

How will we measure that? Through relationships and reach.

2015 goal: ongoing learning activity in 500 cities

In 2015, our key performance indicator (KPI) is to establish ongoing, on-the-ground activity in 500 cities around the world. The key word is ongoing — we’ve had big success in one-off events through programs like Maker Party. This year, we want to grow those tiny sparks into ongoing, year-round activity through clubs and lasting networks.

From one-off events to lasting Clubs and Networks

Maker Party events help active and on-board local contributors. Clubs give them something more lasting to do. Hive Networks grow further into city-wide impact.

What are we working on?

These key initiatives:

  2. Web Clubs
  3. Hive Networks
  4. Maker Party
  5. MozFest
  6. Badges

image will provide a new home for all our teaching offerings — including Maker Party.

What we did: developed the site, which will soft launch in late April.

What’s next: adding dynamic content like blogs, curriculum and community features. Then make it easier for our community to find and connect with each other.


Web Clubs

We shipped the model and tested it in 24 cities. Next up: train 10 Regional Coordinators. And grow to 100 clubs.

This is a new initiative, evolved from the success of Maker Party. The goal: take the sparks of activation created through Maker Party and sustain them year-round, with local groups teaching the web on an ongoing basis — in their homes, schools, libraries, everywhere.

What we did:

  • Established pilot Clubs in 24 cities. With 40 community volunteers.
  • Shipped new Clubs curriculum, “Web Literacy Basics.”
  • Field-tested it. With 40 educators and learners from 24 cities, including Helsinki Pune, Baltimore, Wellington and Cape Town.
  • Developed a community leadership model. With three specific roles: Club Leader, Regional Coordinator, and Organizer. (Learning from volunteer organizing models like Obama for America, Free the Children and Coder Dojo.)

What’s next:

  • Train 10 Regional Coordinators. Each of whom will work to seed 10 clubs in their respective regions.
  • Develop new curriculum. For Privacy, Mobile and “Teach like Mozilla.”
Hive Networks

What we did:

We added four new cities in Q1, bringing our total to 11. Next up: grow to 15.

  • We welcomed 4 new cities into the Hive family: Hive Vancouver, Mombasa, Denver and Bangalore.
  • Made it easier for new cities to join. Clarified how interested cities can become official Hive Learning Communities and shipped new “Hive Cookbook” documentation.

What’s next:

  • Strengthen links between Clubs and new potential Hives. With shared community leadership roles.
  • Document best practices. For building sustainable networks and incubating innovative projects.
  • Ship a fundraising toolkit. To help new Hives raise their own local funding.
Surman Keynote for Day One - Edit.005 Maker Party

A global kick-off from July 15 – 31, seeding local activity that runs year-round.

What we did: created a plan for Maker Party 2015, building off our previous success to create sustained local activity around teaching web literacy.

What’s next: this year Maker Party will start with a big two-week global kick-off campaign, July 15-31. We’ll encourage people to try out activities from the new Clubs curriculum.

Mozilla Festival

This year’s MozFest will focus on leadership development and training

Mark your calendars: MozFest 2015 will take place November 6 – 8 in London.
A key focus this year is on leadership development; we’ll offer training to our Regional Co-ordinators and build skill development for all attendees. Plus run another Hive Global meet-up, following on last year’s success.

What’s next: refine the narrative arc leading up to MozFest. Communicate this year’s focus and outcomes.


What we did: In Q1 our focus was on planning and decision making.

What’s next: improve the user experience for badge issuers and earners.

Community voices
  • “I run two tech programmes in Argentina. I do it outside of my job, and it can be tricky to find other committed volunteers with skills and staying power. I’d love help, resources and community to do it with.” –Alvar Maciel, school teacher, Buenos Aires, Argentina
  • “I always thought I’d visit websites. Not make them! But now I can.” – middle school student from PASE Explorers, NYC afterschool program
  • “Our partnership with Hive makes us fresh, keeps us moving forward rather than doing the same old thing all the time.” –Dr. Michelle Larson, President and CEO, Adler Planetarium, Hive Chicago
  • “We had constant demand from our community members for web literacy classes, and we were finally able to create a great recipe with Web Clubs and curriculum.” –Elio Qoshi, Super Mentor/Mozilla Rep, Albania

The focus this year is on building partnerships that help us: 1) activate more mentors and 2) reach more cities. This builds on the success of partnerships like National Writing Project (NWP) and CoderDojo, and has sparked conversations with new potential partners like the Peace Corps.

Key challenges
  • It’s hard to track sustained engagement offline. We often rely on contributors to self-report their activity — as much of it happens offline, and can’t be tracked in an automated way. How can we incentivize updates and report-backs from community members? How do other organizations tackle this?
  • Establishing new brand relationships. We’ve changed our branding. Our current community of educators grew in deep connection with Webmaker. But in 2015 we made a decision to more closely align learning network efforts directly with the Mozilla brand. How can we best transition the community through this, and simplify our overall branding?
  • Quantifying impact. We’re getting better at demonstrating quantity, as in the numbers of events we host or cities we reach. But those measurements don’t help us measure the net end result or overall impact. How do we get better at that?

Mozilla Science Lab: Mozilla Science Lab Week in Review, April 6-12

ma, 13/04/2015 - 17:00

The Week in Review is our weekly roundup of what’s new in open science from the past week. If you have news or announcements you’d like passed on to the community, be sure to share on Twitter with @mozillascience and @billdoesphysics, or join our mailing list and get in touch there.

Blogs & Articles
  • Erin McKiernan put the call out on Twitter last week for examples of collaborations arising from open science & open data, and got a great spectrum (from worm simulations to text mining Phillip K. Dick) of responses; see her summary here.
  • Hackaday interviewed Charles Fracchia of the MIT Media Lab on the need and impact of open hardware in open science. Fracchia makes the observation that reproducibility is well-served by distributing standardized data collection hardware that can be deployed in many labs & conditions.
  • Figshare blogged recently about decisions taken by the US Health & Human Services department obliging its operating divisions to make government funded research data available to the public.
  • Jonathan Rochkind blogged on the general unusability of institutional library paywall & login systems, and discusses potential solutions in the form of LibX, bookmarklets and Zotero & co.
  • Nature Biotechnology is engaging in more proactive editorial oversight to ensure the reproducibility of the computational studies it publishes, by way of ensuring the availability of relevant research objects.
  • Shoaib Sufi blogged for the Software Sustainability Institute on their recent Collaborations Workshop 2015. In it, Sufi highlights some of the trends emerging in the conversation around developing research software, including the cultural battle in research with imposter phenomenon (see also our recent article on this matter), and the rising profile of containerization as a fundamental tool for reproducible research.
Conferences & Meetings
  • OpenCon 2015 has been announced for 14-16 November, in Brussels, Belgium. From the conference’s website, ‘the event will bring together students and early career academic professionals from across the world to learn about the issues, develop critical skills, and return home ready to catalyze action toward a more open system for sharing the world’s information — from scholarly and scientific research, to educational materials, to digital data.‘ Applications for OpenCon open on 1 June; updates are available from their mailing list. Also, here’s Erin McKiernan’s thoughts on OpenCon 2014.
  • Jake VanderPlas gave a great talk on Fast Numerical Computing with NumPy at PyCon 2015 on Friday.
  • The European Space Agency is organizing a conference entitled Earth Observation Science 2.0 at ESRIN, Frascati, Italy, on 12-14 October.  Topics include open science & data, citizen science, data visualization and data science as they pertain to earth observation; submissions are open until 15 May.
  • The French National Natural History Museum is planning three open forums on biodiversity, designed to collect broad-based input to inform the theme and goals of a forthcoming observatory. The project extends the principles of citizen science to include the public in the discussion surrounding not just data collection, but scientific program design.
Tools & Services
  • Harvard’s project has made CC0 the default license for all data deposited therein in their version 4.0, citing the license’s familiarity to the open data community.
  • The US Federal government’s open data portal,, has created a new theme section highlighting climate & human health data. From their website, ‘The Human Health Theme section allows users to access data, information, and decision tools describing and analyzing climate change impacts on public health. Extreme heat and precipitation, air pollution, diseases carried by vectors, and food and water-borne illnesses are just some of the topics addressed in these resources.
  • GitHub is inviting users to participate in a test of their forthcoming support for the new Git large file storage extension to the popular version control system.
  • The Ocean Observation Initiative, a multi-site array of heavily instrumented underwater observatories, is set to come on-line in June. Data from the OOI is slated for open access distribution.

Chris Ilias: My Installed Add-ons – Keyword Search

ma, 13/04/2015 - 13:41

I love finding new extensions that do things I never even thought to search for. One of the best ways to find them is through word of mouth. In this case, I guess you can call it “word of blog”. I’m doing a series of blog posts about the extensions I use, and maybe you’ll see one that you want to use.

My previous posts have been about:

For this blog post, I’ll talk about Keyword Search.
In Firefox, whenever you do a web search from the location bar, it will use the same search engine as in the search bar. Keyword Search allows you to use a separate search engine for location bar web searches. This is really helpful to people like me who mainly use one search engine (for basic web searches) and others for content-specific use cases.

To set your location bar search engine, go to the add-ons manager.

  1. Beside “Keyword Search“, click Preferences.
  2. Beside “Keyword Search Engine“, select the search engine you want to use.

You can install it via the Mozilla Add-ons site.

Cameron Kaiser: Darwin Nuke the Refrigerator, Wet Sprocket, etc.

ma, 13/04/2015 - 05:04

Two more security notes.

First, as a followup, a couple of you pointed out that there is a writeconfig on 10.4 through 10.6 (and actually earlier) in /System/Library/PrivateFrameworks/Admin.framework/Versions/A/Resources. Yes, there is, and it's even setuid root (I wish Apple wouldn't do that). However, it is not exploitable, at least not by systemsetupusthebomb or a similar notion, because it appears to lack the functionality required for that sort of attack. I should have mentioned this in my prior posting.

Second, Darwin Nuke is now making the rounds, similar to the old WinNuke which plagued early versions of Windows until it was corrected in the Windows 95 days in that you can send a specially crafted packet to an OS X machine and kernel panic it. It's not as easy as WinNuke was, though -- that was as simple as opening a TCP connection to port 139 on the victim machine and sending it nonsense data with the Urgent Pointer flag set in the TCP header. Anyone could do that with a modified Telnet client, for example, and there were many fire-and-forget tools that were even easier. Unless you specifically blocked such connections on ingress, and many home users and quite a few business networks didn't at the time, WinNuke was a great means to ruin someone's day. (I may or may not have done this from my Power Mac 7300 a couple times to kick annoying people off IRC. Maybe.)

Darwin Nuke, on the other hand, requires you to send a specially crafted invalid ICMP packet. This is somewhat harder to trigger remotely as many firewalls and routers will drop this sort of malformed network traffic, so it's more of a threat on an unprotected LAN. Nevertheless, an attacker with a raw socket interface can engineer and transmit such packets, and the technical knowledge required is relatively commonplace.

That said, even on my test network I'm having great difficulty triggering this against the Power Macs; I have not yet been able to do so. It is also not clear if the built-in firewall protects against this attack, though the level at which the attack exists suggests to me it does not. However, the faulty code is indeed in the 10.4 kernel source, so if it's there and in 10.10, it is undoubtedly in 10.5 and 10.6 as well. For that reason, I must conclude that Power Macs are vulnerable. If your hardware (or non-OS X) firewall or router supports it, blocking incoming ICMP will protect you from the very small risk of being hit at the cost of preventing pings and traceroutes into your network (but this is probably what you want anyway).

Even if you do get nailed, the good news (sort of) is that your computer can't be hacked by this method that anyone is aware of; it's a Denial of Service attack, you'll lose your work, you may need to repair the filesystem if it does so at a bad time and that sucks, but it doesn't compromise the machine otherwise. And, because this is in open source kernel code, it should be possible to design a fix and build a new kernel if the problem turns out to be easier to exploit than it appears currently. (Please note I'm not volunteering, at least, not yet.)

So, you can all get out of your fridges now, mmkay?

10.4Fx 38 and IonPower update: 50% of V8 passes and I'm about 20% into the test suite. Right now wrestling with a strange bug with return values in nested calls, but while IonPower progress is slow, it's progress!

Mike Conley: Things I’ve Learned This Week (April 6 – April 10, 2015)

zo, 12/04/2015 - 16:50
It’s possible to synthesize native Cocoa events and dispatch them to your own app

For example, here is where we synthesize native mouse events for OS X. I think this is mostly used for testing when we want to simulate mouse activity.

Note that if you attempt to replay a queue of synthesized (or cached) native Cocoa events to trackSwipeEventWithOptions, those events might get coalesced and not behave the way you want. mstange and I ran into this while working on this bug to get some basic gesture support working with Nightly+e10s (Specifically, the history swiping gesture on OS X).

We were able to determine that OS X was coalescing the events because we grabbed the section of code that implements trackSwipeEventWithOptions, and used the Hopper Disassembler to decompile the assembly into some pseudocode. After reading it through, we found some logging messages in there referring to coalescing. We noticed that those log messages were only sent when NSDebugSwipeTrackingLogic was set to true, we executed this:

defaults write org.mozilla.nightlydebug NSDebugSwipeTrackingLogic -bool YES

In the console, and then re-ran our swiping test in a debug build of Nightly to see what messages came out. Sure enough, this is what we saw:

2015-04-09 15:11:55.395 firefox[5203:707] ___trackSwipeWithScrollEvent_block_invoke_0 coalescing scrollevents 2015-04-09 15:11:55.395 firefox[5203:707] ___trackSwipeWithScrollEvent_block_invoke_0 cumulativeDelta:-2.000 progress:-0.002 2015-04-09 15:11:55.395 firefox[5203:707] ___trackSwipeWithScrollEvent_block_invoke_0 cumulativeDelta:-2.000 progress:-0.002 adjusted:-0.002 2015-04-09 15:11:55.396 firefox[5203:707] ___trackSwipeWithScrollEvent_block_invoke_0 call trackingHandler(NSEventPhaseChanged, gestureAmount:-0.002)

This coalescing means that trackSwipeEventWithOptions is only getting a subset of the events that we’re sending, which is not what we had intended. It’s still not clear what triggers the coalescing – I suspect it might have to do with how rapidly we flush our native event queue, but mstange suspects it might be more sophisticated than that. Unfortunately, the pseudocode doesn’t make it too clear.

String templates and toSource might run the risk of higher memory use?

I’m not sure I “learned” this so much, but I saw it in passing this week in this bug. Apparently, there was some section of the Marionette testing framework that was doing request / response logging with toSource and some string templates, and this caused a 20MB regression on AWSY. Doing away with those in favour of old-school string concatenation and JSON.stringify seems to have addressed the issue.

When you change the remote attribute on a <xul:browser> you need to re-add the <xul:browser> to the DOM tree

I think I knew this a while back, but I’d forgotten it. I actually re-figured it out during the last episode of The Joy of Coding. When you change the remoteness of a <xul:browser>, you can’t just flip the remote attribute and call it a day. You actually have to remove it from the DOM and re-add it in order for the change to manifest properly.

You also have to re-add any frame scripts you had specially loaded into the previous incarnation of the browser before you flipped the remoteness attribute.1

Using Mercurial, and want to re-land a patch that got backed out? hg graft is your friend!

Suppose you got backed out, and want to reland your patch(es) with some small changes. Try this:

hg update -r tip hg graft --force BASEREV:ENDREV

This will re-land your changes on top of tip. Note that you need –force, otherwise Mercurial will skip over changes it notices have already landed in the commit ancestry.

These re-landed changes are in the draft stage, so you can update to them, and assuming you are using the evolve extension2, and commit –amend them before pushing. Voila!

Here’s the documentation for hg graft.

  1. We sidestep this with browser tabs by putting those browsers into “groups”, and having any new browsers, remote or otherwise, immediately load a particular set of framescripts. 

  2. And if you’re using Mercurial, you probably should be.

Nick Cameron: New tutorial - arrays and vectors in Rust

zo, 12/04/2015 - 03:36
I've just put up a new tutorial on Rust for C++ programmers: arrays and vectors. This covers everything you might need to know about array-like sequences in Rust (well, not everything, but at least some of the things).

As well as the basics on arrays, slices, and vectors (Vec), I dive into the differences in representing arrays in Rust compared with C/C++, describe how to use Rust's indexing syntax with your own collection types, and touch on some aspects of dynamically sized types (DSTs) and fat pointers in Rust.
