Kanban & Web Productions: Lessons Learned

Benjamin Sternthal

Kanban has been making in-roads at Mozilla, and this is no small feat considering the size and complexity of the organization. I’d like to think our team has influenced folks, either to adopt Kanban, or to at least think about alternative development methodologies. Below is the history of how Web Productions came to use Kanban and the lessons we learned along the way.

Unfortunately, I wasn’t able to attend the “show and tell” meetings recently so there aren’t any updates from there.

Lightning Talk Bonus Round

Michael Kelly

It was raining when the idea first came to me. Deep within the disappointingly well-lit halls of my local coworking spot, I sat in a meditative state as I contemplated the problem of sharing knowledge among the Web Productions team. As my mind drifted in and out of various realities, I came upon a world in which the only television show was the Price is Right. Taking inspiration from the wondrous paradise that this world was, I decided the proper solution was to create a monthly event: Lightning Talk Bonus Round!

Essentially, once a month the Web Productions team gets together to share short 5-15 minute talks on any subject we desire, from programming languages to design principles to mycology. We’re still working out the format and technical details, so there are no recordings available… yet. In the future, we hope to record the event and open it up to the community.

The first Lightning Talk Bonus Round was on June 3rd, 2013. There is a wiki page with links to the notes and details about each of the talks.

Craig Cook – Design Principles

Craig Cook gave a shortened version of a longer talk focused on the basics of Design Principles. He discussed controlling the balance between elements on a page to indicate which elements are more important than others. He also discussed using proximity, repetition, and contrast to help visually distinguish elements and establish the hierarchy of important on a page through visual cues. You can check out his slides on GitHub.

Giorgos Logiotatidis – Django Anonymizer

Next, Giorgos showed us Django Anonymizer, which is a Django app to help you anonymize existing data in the database. As opposed to other methods, such as maintaining fixtures or generating random data, with Django Anonymizer you’d start with a copy of your production data and configure the app to anonymize it, leaving you with data that is anonymous but still looks similar to the data you’d see in production.

This is especially useful in situations where production data may end up with interesting relationships between data that are hard to replicate when generating random data from the start. The Django Anonymizer project is available on PyPI. You can also see Giorgos’s notes in a gist.

Paul McLanahan – virtualenvwrapper and hub

Lastly, Paul talked about two tools that he finds useful during day-to-day development: virtualenvwrapper and hub. virtualenvwrapper is a set of extensions to virtualenv, which creates isolated Python environments for projects that need specific versions of Python or other libraries. The extensions come in the form of commands that help you quickly create, activate, and delete virtual environments. There are also hooks that let you execute certain commands when environments are created, activated, or deleted.

hub is a command-line wrapper for git that has extra commands tailored for working with GitHub. You can clone a repository using just a username and repository name, automatically create a fork on your GitHub account, or even create a pull request for a branch, all directly from the command prompt.

Great Success!

As I gaze over the majestic glory that is the aftermath of Lightning Talk Bonus Round, I realize that we have only just started. My work shall continue, on the first Monday of each month at 10 AM Pacific, in the hopes that someday we will be able to avoid all this knowledge sharing and pool together in a mindspace where thoughts mingle like so many fish in an ocean of web development.

Until then, we shall have to do what we can in meatspace. See you next month!

Upcoming:

We also do a weekly “show and tell” of things that people have done in the Apps group every week. This is a summary of some of the things that have been shown there.

  • Touch events are now possible in the simulator. Myk demonstrated that click and drag with a mouse is now the same as touch events on the device. Available in the preview version.
  • The simulator “push to device” now works on 64 bit linux because adb has successfully been compiled for that platform.
  • App refresh will automatically detect changes in apps installed into the simulator from the Marketplace. Also command-shift-r refreshes but also clears the application cache.
  • Chris showed off the pending review queue addition to the Marketplace. This allows app developers to see how long they have to wait in the review queue.
  • Amy reported that the review team has onboard five new volunteer reviewers for the Marketplace.
  • Basta showed that the Marketplace JavaScript has decreased in size by using a custom JQuery build. Check out the current size.
  • The Marketplace region is now set from the SIM card.

We were also joined on the Marketplace team by Mathieu Pillard. Welcome to the Marketplace team, Mathieu.

The Crimson Twins

Mike Cooper

Crimson Twins is a project that I started at Mozilla to power two ambient
displays that we mounted on the wall in the Mountain View Mozilla office. We
use it to show dashboards, such as the current status of the sprint or the state of GitHub. We also use it to share useful sites, such as posting a YouTube video that is related to the current conversation. Most of the time that I pay attention to the Twins, is when my coworkers and I post amusing animated GIFs to distract amuse the rest of the office.

DXR Digests the Firefox Codebase

Erik Rose

4

How do you reason about a codebase the size of Firefox’s? How do you figure out who calls the function you’re messing with, without losing your context in an endless stream of false-positive-infested greps?

You bust out DXR, Mozilla’s code search and static analysis tool.

DXR begins with the technology that powered the much-missed Google Code Search: inverted trigram indices which turbo-charge a fast regex implementation. It then adds a static analysis engine that rides sidecar with the C++ compiler, noting the location and relationship of code constructs. As a result, you can not only do regex searches that return as fast as you can type, but you can also ask “Who subclasses this?” “Where is this macro defined?” and “Where are all the references to this type?”

Last week saw the first production push of DXR since its major redesign early this year. It now rides on a modern foundation of Flask and WSGI; blocks regressions with a looser-coupled, higher-coverage test harness; and delivers a glut of new features and fixes. Here are some highlights.

Indexing and Search

  • Faster, index-accelerated performance on many kinds of queries
  • Querying for callers and callees
  • Ability to find callers of constructors
  • Recognition of typedefs
  • Links to macro references
  • Links from class declarations to class definitions
  • Better detection of JS symbols
  • Differentiation between a const and a non-const function of the same name
  • Handy-dandy path breadcrumbs so you can tell what file you’re reading and move around in the source tree
  • Sorted folder listings
  • First-class support for mobile and WebKit

Infrastructure

  • Several thousand lines less code
  • Slimmer builds which consist of only data, not Python code, making development easier and deployment cleaner
  • Replacement of our ad hoc process pooling implementation with Python 3’s concurrent.futures (knocking off about 200 lines)
  • Flask-powered WSGI instead of old-school CGI
  • Redesigned URLs for MXR parity and future extensibility
  • A Vagrant box to ease the spin-up of new contributors
  • A brand new test harness, exercised by a Vagrant-based Jenkins job

Bug Fixes

  • Trouble-free entry of queries. (Bad JS! Go sit in the corner.)
  • A fix for a crash when doing negated phrase matching
  • Fixes for URL- and HTML-escaping bloopers, including shameful XSSes
  • No more duplicate result lines in some types of queries

What’s Next?

I am pleased to announce that the next release is scheduled for one minute from now. Yes, DXR is now under continuous deployment: if it passes tests, it goes up on the servers, eliminating human bottlenecks and errors and letting us deliver goodies—and get feedback—promptly. A great many UI and capability enhancements are on deck next, along with speedy new server hardware to make queries even snappier.

Better know a WebDev: Jennifer Fong

Andy McKay

Featuring Jennifer Fong, also known as ednapiranha.

What do you do at Mozilla?

I am on the Developer Ecosystem team and work on the Developer Hub, build reference apps and help developers build apps for the Firefox Marketplace.

Any fun side projects you’re working on?

Yes – let’s see:

  1. Recently created meatspace, a node module that supports decentralized microblogging functionality and subscriptions. Think of it like RSS as JSON feeds packaged with CRUD on posts.
  2. As a result, I made generaltoast, which is a Node/Express app that uses meatspace and Persona to exemplify a web interface for meatspace. You can check out my current microblog – left side are my posts, right side are my subscriptions to other posts.
  3. For a reference app in the Firefox Marketplace, I made generalnotes which is a note-taking app that syncs to the server when the user is online and logged in. Check out the accompanying blog post.
  4. As an attempt to create an interactive fiction game engine, I created generalstore, which allows a user to create a game with text files, images, audio files and CSS.
  5. I am also organizing the remote-friendly NoodleConf, which is an atypical one day conference where speakers talk about whatever they want. Likely relating to technology. Or possibly what they ate for breakfast.

How did you get started in web development or programming?

High school – Watcom Basic and Turing if we really want to be technical about it. Web development was during my later years. Something something PHP something – Aphex Twin may or may not have been playing in the background.

How did you get involved with Mozilla?

I was riding this unicorn across the great Canadian forests and a rainbow appeared in the sky. I followed to the end of the rainbow and saw a job application to join Mozilla. The unicorn touched the application with its horn. The rest is history.

What’s a funny fail or mistake story you can share?

On my first week at Mozilla, I accidentally did a git push -f to master for http://mozillians.org. I felt so bad, but I got over it pretty quickly.

What’s something you’re particularly proud of?

Having some really weird friends. And ideas.

What’s coming up that you’re excited about?

NoodleConf 2013!
