Things I’ve Learned This Week (March 23 – 27, 2015)

This is the first post in a weekly series, where I’m going to attempt to distill down my week into some lessons or facts I’ve picked up. Maybe they’ll be interesting to others. We’ll see.

  1.  Gecko Media Plugins are used both for WebRTC (the Open H.264 encoding stuff runs inside a GMP), and is also going to be used to hold CDM’s for EME’s. That’s a lot of TLA’s!1
  2. This little notch I saw on the caret on my development build was because I had bidi.browser.ui set to true for some reason. It’s the “bidi caret”:
    Bidi Caret
  3. People hacking on platform are supposed to avoid using the NS_ENSURE_* macros, according to this.2 I originally learned this by reading cpearce’s review of a patch.

So let’s see if I can keep this up for a few weeks. Maybe I’ll get a collection of useful stuff by the end of the experiment!

  1. Three Letter Acronyms ↩

  2. It says:

    Previously the NS_ENSURE_* macros were used for this purpose, but those macros hide return statements and should not be used in new code.
