**** BEGIN LOGGING AT Wed Jan 23 02:59:59 2013 Jan 23 03:06:47 https://hacks.mozilla.org/2013/01/announcing-the-firefox-os-developer-preview-phone/ Jan 23 10:43:31 * PaulFertser is using an armel chroot thanks to qemu userspace emulation plus self-compiled distcc to actually use a cross-compiler which is much faster. Jan 23 10:59:08 (self-compiled distcc is needed to disable sendfile feature which is not supported by qemu-arm) Jan 23 15:23:12 GNUtoo-m4a785t-m, forwarding your advice, I have done rtp, but software encode is really slow, the teacher let me do MFC(hardware encode), if I write a plugin for gst, does it it the best way Jan 23 15:25:23 sorry, is it the best way, I meant that Jan 23 15:40:02 yes Jan 23 15:42:10 else you can play with less compressed formats Jan 23 15:42:15 such as mjpeg etc... Jan 23 16:32:24 I think that board is a simle board, maybe a good board for learning, but if I write a dts for it, will it be accepted? Jan 23 18:42:12 I wonder whom should i pay and how much to get any cell-phone device _rock_solid_ (all the parts) and daily-usable with FSO? Jan 23 18:47:47 I wonder why the hell one day usb networking works flawlessly with my FR and another it stops. Jan 23 18:48:33 I wonder why sometimes i wake up in the morning and see my gta02 fully discharged while being on USB? I fucking fixed that driver myself long time ago, what else might prevent it from working? Low USB voltage like with gta04 or what? Jan 23 18:49:30 Seriously, how much would it cost me to have all the FSO tickets i opened investigated and closed? Jan 23 18:52:07 PaulFertser: I have had two cases of broken usb cables Jan 23 18:53:34 lindi-: different usb cables here Jan 23 18:53:48 lindi-: was usb networking always rock-solid for you? Jan 23 18:55:04 Sometimes i replug, the device is visible again, works for a while and then communication is inhibited. Jan 23 18:55:29 lindi-: btw, have you got any news wrt that voip phones manufacturer? Jan 23 19:05:01 PaulFertser: nothing that's public yet :) Jan 23 19:05:51 PaulFertser: usb networking is rock-solid for me on my gta02 Jan 23 19:05:52 lindi-: :) Jan 23 19:06:17 however, suspend and gsm are not Jan 23 19:06:57 Hm, i guess it really depends on the cable then. I tried a sucky one at work today and i'm always using a questionable usb extender at home. Hm, so that might be the case indeed. Jan 23 19:07:07 But i can try it right now without the extender. Jan 23 19:07:23 dos1: what kernel version are you on? Jan 23 19:07:30 And how the hell gsm is still not stable? Jan 23 19:08:40 i was on 2.6.39, but due to "i don't like you so i won't wake up from suspend" issue switched back to 2.6.37 Jan 23 19:09:18 sometimes gsm calls start to timeout Jan 23 19:09:19 2.6.39.4 for me Jan 23 19:09:46 It resumes most of the time but not always, like once in 50 times it doesn't. Jan 23 19:10:01 yeah it's a known issue Jan 23 19:10:04 I use 2.6.34 Jan 23 19:10:12 dos1: do you know the SoC itself is rated for a lower voltage than Calypso so you can have device running but modem disfunctional? Jan 23 19:10:16 lindi-: yes, i know Jan 23 19:10:40 Hm, without the usb extender it seems to work now. Jan 23 19:10:46 lindi-: thanks for reminding me! Jan 23 19:10:59 I wonder though why the same extender works with high-speed usb without issues :/ Jan 23 19:11:27 PaulFertser: usb specification has this chapter titled "forbidden cable assemblies" Jan 23 19:11:34 PaulFertser: one of them is "extension cable" ... Jan 23 19:12:20 lindi-: an good short extension cable itself can not be an issue i think. Jan 23 19:13:09 lindi-: hm, i think you have full RAM dumps for 2.6.39 when it fails to resume, right? Do you think the bug is really hard to track down? Jan 23 19:13:37 PaulFertser: probably solvable in a few weeks but I'm busy with my thesis :) Jan 23 19:13:58 lindi-: may i ask you what your thesis is about? Jan 23 19:14:29 PaulFertser: more compact alternative to LLVM bitcode Jan 23 19:15:13 :-O Jan 23 19:15:21 PaulFertser: I don't think that's an issue, but I'll watch my battery when it happens again - didn't know that, thanks Jan 23 19:15:39 But compactness often comes with a price, probably executing that compact bytecode would be slower? Jan 23 19:16:39 PaulFertser: well you can convert it back to the original bitcode format after you have transmitted it over some low-bandwidth link for example Jan 23 19:16:48 PaulFertser: it's lossless data compression Jan 23 19:17:22 lindi-: what is the possible usecase? Jan 23 19:17:50 PaulFertser: distributing software as LLVM IR Jan 23 19:18:29 PaulFertser: for example google portable native client plans to distribute software in IR format instead of native code Jan 23 19:18:53 PaulFertser: http://www.chromium.org/nativeclient/pnacl/building-and-testing-portable-native-client Jan 23 19:22:05 PaulFertser: also there's just some academic interest. bitcode already tries to do a lot of tricks to stay compact but the format that I developed is much simpler but still takes less space Jan 23 19:22:19 lindi-: please excuse me, probably i'm too tired today, but i can't yet understand why someone might want to distribute software in LLVM IR form. Jan 23 19:22:42 PaulFertser: well then you only need one IR for all ARM variants for example Jan 23 19:22:47 Academic interest is something that i understand, yes, that's of course a great thing. Jan 23 19:23:58 But then you'll need to have an optimising IR->native compiler on the target anyway. Why not compile from the sources then if hosting and distributing binaries for all the ARM variants is for some reason unsuitable? Jan 23 19:24:01 PaulFertser: another thing is the "life-long optimization" idea. optimizations at link-time, install-time and run-time Jan 23 19:24:25 PaulFertser: well obviously sources take even more space Jan 23 19:24:36 PaulFertser: http://llvm.org/pubs/2004-01-30-CGO-LLVM.pdf explains this "life-long optimization" idea Jan 23 19:24:49 PaulFertser: figure 4 Jan 23 19:25:32 PaulFertser: also you can run the IR with a JIT to get more performance in some cases Jan 23 19:26:16 A JIT faster than native code? Jan 23 19:28:42 dos1: and another known calypso problem is when you have steady fast GPRS data transfer, the firmware bugs out. Jan 23 19:28:53 dos1: lindi- discovered it and proposed a tc workaround. Jan 23 19:29:38 it may be that, i'm often leaving gprs enabled Jan 23 19:30:22 dos1: is gta02 your only cellphone? Jan 23 19:30:29 dos1: http://docs.openmoko.org/trac/ticket/2264 Jan 23 19:31:06 well, i still have some old nokias around, but i'm actively using only gta02 Jan 23 19:31:26 around or carrying with you? Jan 23 19:32:10 around Jan 23 19:34:00 I have an old nokia 1100 and i used it when going to a several days open-air music fest. Jan 23 19:36:31 that bug looks very interesting Jan 23 19:39:20 hi Jan 23 19:39:22 I thought everybody knew about it Jan 23 19:39:36 what bug? Jan 23 19:40:12 PaulFertser: i missed it somehow... Jan 23 19:40:22 GNUtoo-m4a785t-m: http://docs.openmoko.org/trac/ticket/2264 Jan 23 19:40:44 well, i never really used gprs very often on gta02 until recently Jan 23 19:45:23 I do not know which browser to use. Jan 23 19:46:27 I'd like something like links2 -g but with tabs, ability to selectively enable/disable pictures... Jan 23 19:46:36 I'd like to have a bigger screen and a real keyboard. Jan 23 19:46:42 I'd like n900, hell! Jan 23 19:48:33 ah that one Jan 23 19:49:12 I have to finally fix my n900 ;_; Jan 23 19:49:25 PaulFertser: I thought you've got n900? Jan 23 19:49:54 dos1: yes, i've got one, but hardware worth little without software Jan 23 19:50:16 oh, right Jan 23 19:54:58 dos1, maybe you want to fix the n900 forwarder in fso? Jan 23 19:55:57 when my n900 will work again, then why not Jan 23 20:00:45 I'm not sure it'd be useful still, i haven't heard about any decently working n900 kernel anyway :( Jan 23 20:02:16 that sucks Jan 23 20:04:45 You know, 1.5 years ago i've got a netbook, a barely used Toshiba ac100. And that's a device that i keep using regularly and which is mostly not a pain to use. As a bonus, i have it's UART exposed and easily accessible from the outside since day one, used it for some uC projects. Jan 23 20:04:53 PaulFertser, there is one Jan 23 20:04:54 But even that awesome netbook sucks! Jan 23 20:04:57 from arch Jan 23 20:11:40 PaulFertser: well the JIT can dynamically adjust to the workload Jan 23 20:12:43 PaulFertser: I'm going to migrate away from gta02 soon mostly because it lacks memory for running a modern browser Jan 23 20:13:39 lindi-: i do not like modern browsers because they tend to try to cope with modern internet which sucks :( Jan 23 20:14:46 PaulFertser: heh Jan 23 20:52:22 GNUtoo-x60: you've told me there's one before but so far i have not seen anyone who'd say he use it daily and shared the results wrt stability and power consumption. Jan 23 20:53:57 ok Jan 23 20:55:31 Have you? Jan 23 21:15:46 btw, why are there people interested in webos, what are they hoping for, a useable platform? **** ENDING LOGGING AT Thu Jan 24 02:59:58 2013
