[04:04] <RAOF> Woot! Overlayfs works on mainline kernels now!
[04:21] <RAOF> Hm, odd.
[04:21] <RAOF> I can't build lp:mir.
[05:38] <RAOF> It takes *quite* a long time to build mir on a virtualised armhf.
[05:54] <duflu> RAOF: If just Mir, cross-compile?
[05:54] <RAOF> Want to build packages :)
[05:55] <duflu> RAOF: Would getting one of those Exynos chromebooks help?
[05:55] <RAOF> Yes.
[05:56] <RAOF> Or a beaglebone, probably.
[05:56] <duflu> Well, chromebook has a keyboard, screen etc.
[05:56] <duflu> And rooting a chomebook is relatively friendly
[05:56] <RAOF> And costs > 4× as much :)
[05:57] <duflu> RAOF: Sure, but how much for a case + keyboard + display + ... ?
[05:57] <RAOF> Why would I need any of those?
[06:01] <duflu> Ha. On another note: Why does Android let you set the year back to 1970? Seems like a waste of scroll menu space
[06:02] <duflu> The obvious answer is because it's Linux (Unix), but still...
[08:59] <alan_g> duflu: do you happen to know a quick way to convert a gimp-generated image struct from unpremultiplied-alpha to premultiplied (to avoid doing the runtime computation)?
[08:59] <duflu> alan_g: Runtime would be "free" because you only need to do it once on startup
[09:00] <duflu> (modify it in place)
[09:00] <alan_g> duflu: I realise its cheap at runtime. Was just wondering
[09:01]  * duflu didn't really want to spend Friday afternoon triaging graphics glitches on the phone, but is...
[09:04] <duflu> alan_g: I think best to store the image in pure alpha format and pre-multiply in code (where the requirement for premultiplied exists)
[09:04] <alan_g> duflu: OK. Thanks
[09:05] <duflu> Hmm, doesn't alpha pre-multiplication mean we lose colour precision?
[09:05] <duflu> (colour precision in the final blended result)
[09:06] <alan_g> Possibly. Although in this case it is no worse than the code I'm trying to kill.
[09:42] <duflu> alan_g: Any update to make in this? https://bugs.launchpad.net/mir/+bug/1341490
[09:44] <alan_g> duflu: I'll write something
[09:46] <duflu> Man, I think I wrote about 10 lines of code today. And spent the rest of the time re-discovering long-standing bugs that I needed to remember to work around
[13:22]  * alan_g has a simple 22.6K line MP up for review: https://code.launchpad.net/~alan-griffiths/unity-system-compositor/incorporate-logo-into-spinner-binary/+merge/261181
[13:40] <anpok_> ah yes line 4979 looks supicious
[13:47] <alan_g> It's just steganography
