The Joy of Coding (Episode 6): Plugins!

In this episode, I took the feedback of my audience, and did a bit of code review, but also a little bit of work on a bug. Specifically, I was figuring out the relationship between NPAPI plugins and Gecko Media Plugins, and how to crash the latter type (which is necessary for me in order to work on the crash report submission UI).

A minor goof – for the first few minutes, I forgot to switch my camera to my desktop, so you get prolonged exposure to my mug as I figure out how I’m going to review a patch. I eventually figured it out though. Phew!

The Joy of Coding (Episode 5): Much Code Review

In this fifth episode, I didn’t work on any bugs. Instead, I did a bunch of code review. Ever wanted to know what a Firefox engineer does to review a patch? If so, then this episode is for you!

The Joy of Coding (Episode 4)

The fourth episode is up! Richard Milewski and I found the right settings to get OBS working properly on my machine, so this weeks episode is super-readable! If you’ve been annoyed with the poor resolution for past episodes, rejoice!

In this fourth episode, I solve a few things – I clean up a busted rebase, I figure out how I’d accidentally broken Linux printing, I think through a patch to make sure it does what I need it to do, and I review some code!

The Joy of Coding (Episode 3)

The third episode is up! My machine was a little sluggish this time, since I had OBS chugging in the background attempting to do a hi-res screen recording simultaneously.

Richard Milewski and I are going to try an experiment where I try to stream with OBS next week, which should result in a much higher-resolution stream. We’re also thinking about having recording occur on a separate machine, so that it doesn’t bog me down while I’m working. Hopefully we’ll have that set up for next week.

So this third episode was pretty interesting. Probably the most interesting part was when I discovered in the last quarter that I’d accidentally shipped a regression in Firefox 36. Luckily, I’ve got a patch that fixes the problem that has been approved for uplift to Aurora and Beta. A point release is also planned for 36, so I’ve got approval to get the fix in there too. \o/

Here are the notes for the bug I was working on. The review feedback from karlt is in this bug, since I kinda screwed up where I posted the review request with MozReview.

The Joy of Coding (Episode 2)

The second episode is up! We seem to have solved the resolution problem this time around – big thanks to Richard Milewski for his work there. This time, however, my microphone levels were just a bit low for the first half-hour. That’s my bad – I’ll make sure my gain is at the right level next time before I air.

Here are the notes for the bug I was working on.

And let me know if there’s anything else I can do to make these episodes more useful or interesting.
