Games [1st Tuesday of Month]

Mobile Web Compat [2nd Tuesday of Month]

  • Lawrence gave an update during yesterday's project meeting. Video, Slides
  • Test event today, 12pm PT in 10 forward and on Air Mozilla.

Critsmash [3rd Tuesday of Month]

MemShrink [4th Tuesday of Month]

  • Memory consumption is critical for B2G. Lots of work is being done, especially by Justin Lebar. Hopefully it will be enough at this late stage. The tracking bug is here.
  • Gary Kwong got Valgrind tests green on tinderbox. Next steps are to run them on more test suites, more repos and more often -- often enough to unhide the results. This will require (moderate) releng resources that are currently strained by B2G.
  • We're watching the social API closely for problems such as bug 794712 (which was a Facebook problem). Please file bugs and tag with "[MemShrink]" if you see problems.
