lufUgh. incredible valgrind. It seems I fix the problem. fucking missing () in pointer arithmetic :D00:05
lufBut when I stop obexd it reports something and I'm unable to find the origins ...00:06
kerioyeah, valgrind is srsly cool00:07

luffreemangordon: the bluez upgrade is closer to the tip of my TODO ;) I need to refactor the MAP patch (also merge with last public release) and put it into TMO for testing. Then bluez time will come ;)00:47

freemangordonluf: you did find the bug in obexd?09:38
luffreemangordon: yes. As I disabled mas plugin also syncevolution plugin needs to be disabled (just config) due to bluetooth synchronization.09:39
luffreemangordon: the bug I mentioned is in MAP and I finally have stable initial map (this isn't in released obexd).09:40

*** rantom has joined #maemo-ssu11:43
rantomHi. Can I ask a quick question about tuning the transitions with/for CSSU?11:44
tadzikgo ahead11:47
rantomThanks. :) So I just moved back for, now, to my N900 and tried to customize the transitions with CSSU Features/etc. That didn't work that well though (I'm on CSSU-Stable) and I thought what could I use in its place11:48
rantomNow I found cssutransitionstuner in packages, that's stuck in -testing, would that be good alternative to use since I already have Theme Customizer isntalled?11:49
tadzikhuh. I just switched this .ini file somewhere )11:50
tadziknever used any tool for that11:50
rantomHeh, ok11:51
tadzikI don't change the transitions every few hours, so that seems sensible11:51
tadzikfreemangordon: actually, I can try this gstreamer11:51
rantomYeah, it'll be once the settings are complete11:52
tadzikfreemangordon: just download it all and dpkg -i it?11:52
rantomJust curious overall is there a reason not to use cssutransitionstuner11:52
rantome.g. incompatibility11:52
rantom(which would be a bit ironic considering the name :)11:52

DocScrutinizer05luf: ?? I fthat's what I think it is, you should read about sparQL13:28
DocScrutinizer05I'd guess it means there's a filter on a table, to return all records where the field 'msg' is NOT bound to any data13:44

lufUgh obexd patch againist orig grow from 130kB to 400kB :D15:32
DocScrutinizer05luf: honestly, SPARQL is such a braindamaged crap15:48
lufDocScrutinizer05: true :)15:50
DocScrutinizer05where in a decent language I'd define a condition like NOT ISEMPTY(data-element), in SPARQL I need a mindfsckng OPTIONAL { ?x dc:date ?date } . FILTER (!bound(?date))15:51
lufDocScrutinizer05: :D that's the reason I don't want study such crapy language.15:52
*** _rd has joined #maemo-ssu15:54
lufWow. I finished initial MAP support for obexd. I'll upload it to the git and announce on the TMO.15:57
lufIs someone here interested to test it? :)15:57
*** Pali has joined #maemo-ssu15:58
DocScrutinizer05I'd not know how to test it15:59
DocScrutinizer05for fun, figure how to literally transcode OPTIONAL { ?x dc:date ?date } . FILTER (!bound(?date)) to SQL ;-D16:00
lufI'm still a little bit normal :D16:00
DocScrutinizer05select a.x a.y from mytab as a, b.x  b.z mytab as b where notempty(b.z) and b.x = a.x16:03

lufok, new obexd is in git and also merlin1991.at :) I'll announce it on TMO in the evening or tomorrow. I need to fix dependency for librtcom-eventlogger1-async and rtcom-eventlogger-async.17:08
luffreemangordon: I think I'll take a look on bluez upgrade tomorrow or the day after tomorrow.17:09
freemangordongood, now you're back to BT :P17:09
luffreemangordon: :D as you wish :D17:09
freemangordonluf: don't forget my re-packaging ;)17:09
freemangordon:D:D:D17:09

keriobut i have a laptop, so don't worry17:53
keriofreemangordon: that's a lot of debs D:17:57
kerioalso the versions aren't +thumb17:57
m0shbeari wonder how well-optimized mednafen's and desmume's virtualizations are, in order to avoid as much arm->arm translation as possible18:01
m0shbearsince a ds is pretty much an arm965e and gba an arm7tdmi with a few peripheral fancinesses18:01
freemangordonkerio: yes, no -thumb in version, but that should not be a problem18:09
kerioit IS >:C18:10
freemangordonI thoink you have all, but gstreamer0.10-tools installed18:10
freemangordonkerio: not, it is not, if everything is OK, +thumb version will come with next -pr thing18:10

freemangordonWTF?!?19:00
kerioWTF indeed19:01
freemangordonwell, you may want to not install it19:02
freemangordonthough it contains libgstgdp.so and libgstpango.so19:02
freemangordonwhatever those are used for19:02

freemangordononly what is in stock, but will leave that extra package on the repo too (no option actually, because of the .changes file)19:07

keriothere could be a kernel patch for you19:21
keriofreemangordon: what's the unaligned access thing again?19:21
Paliwhere?19:22
Paliwhat?19:22
*** NIN101 has quit IRC19:22

kerioyay19:49
keriois it faster?19:49
kerioalso yay gcc4.7 for mp319:49
freemangordonfaster? how to check that?19:51
freemangordonunfortunately mp3 is nokia :(19:51
kerio...wtf19:51
keriowhy?19:51
kerioit's fukken gstreamer19:51
freemangordonno idea19:51
keriowell fix it19:51
freemangordonlibgstnokiamp3dec.so19:51
freemangordonpackage gstreamer0.10-nokia-speech19:52
keriothat's bullshit and we both know it19:52
keriofix it19:52
kerioplease ;_;19:52
freemangordonunfortunately the parts that will benefit the most from using gcc4.7.2 are closed source - pulseaudio nokia plugin and gst mp3 decoder :(19:54
freemangordoncurse Nokia for that19:55
freemangordonthere are FOSS mp3 decoders, but those are out of the scope of CSSU-thumb :P19:58
*** m0shbear has joined #maemo-ssu19:59
freemangordonbtw did it come clear why tracker update screwed flac and ogg?20:00
tadzikfreemangordon: why out of scope?20:00
freemangordontadzik: as I am not going to reinvent maemo520:00
tadzikI see20:01
freemangordonfeel free to pester merlin1991 and chem|st to add foss mp3 codec replacement in CSSU-T/S, -thumb will follow shortly :)20:01
ShadowJKiirc kulve already tested ffmpeg's mp3 and vorbis decoder back in 09 or 10, and performance was good20:02
freemangordonShadowJK: hmm, I remember something about that.20:03
freemangordonAnd I suspect it will be much better when optimized with gcc 4.7.220:04
freemangordonbut please, understand that I am the only one working on that20:04
ShadowJKAlso ffmpeg/libav itself will have improved since then20:04
ShadowJKI'd also claim that current perf is "good enough"20:06
ShadowJKand that the difference in battery life measured back then came  probably mostly from different wakeup behaviour rather than cpuseconds used20:07
kerioShadowJK: idk, there's a *big* difference between gcc 4.2 and 4.7-linaro20:13
keriooptimizers are black magic20:13
freemangordonShadowJK: did you see the comparison in openssl benchmarks?20:16
freemangordonthe one compiled with gcc4.7.2 is about 2 times faster for some algos20:17
freemangordonbtw does anyone know if sshd uses openssl?20:18
kerioi'd guess it does20:18
kerioactually no, maybe not20:18
kerioyes it does, it uses libcrypto20:19
freemangordonas i've never seen winscp copying a file with > 1MB/s speed. until an hour ago :D20:19
m0shbearkerio: less black magic than tons of program analysis math20:20
m0shbearthey're becoming as advanced as decompilers, if not at that level, imo20:20
freemangordonShadowJK: http://pastebin.com/Bpdt8nr720:21
ShadowJKis that in cssu thumb?20:24
freemangordonyes20:24
freemangordondevice not overclocked20:24
keriofreemangordon: i wonder how much of that is thumb and how much is gcc 4.720:24
freemangordonit is deffinitely gcc20:25
freemangordonthough AFAIK thumb2 allows compiler to schedule more effectively20:25
* freemangordon wonders is it a good idea to recompile the kernel with gcc4.720:28
*** NIN101 has joined #maemo-ssu20:29
keriodo it20:31
kerioi dare you20:31
freemangordonhehe. I already used 4.6.2 with meego kernel back in the days I was playing with ubuntu 12.04. it was ok20:32
ShadowJKis thumb kernel possible?20:36
*** sixwheeledbeast has joined #maemo-ssu20:38
freemangordonShadowJK: I didn't mean thumb-compiled, but gcc4.7 compiled20:39
freemangordonAFAIK our kernel is too old to be compiled with thumb220:39
freemangordontoo many patches are missing20:40
ShadowJKYeah I know you meant normal20:40
*** dhbiker has quit IRC20:40
freemangordonotherwise even meego kernel can be thumb2-compiled20:40
freemangordon(iirc)20:40
freemangordonthough I cannot imagine what would benefit from gcc4.7 besides filesystems(maybe).20:43
kerio...everything?20:44
kerioidk20:44
ShadowJKThat's why I asked about thumb, smaller codesize could benefit cpu cache etc :)20:51
*** CodenameStrike has quit IRC20:53
freemangordonShadowJK: yeah, but it is too much of a backporting :(21:04
keriofreemangordon: hm, why won't it compile with -mthumb?21:21
* ShadowJK noticed sys cpu use was 20% playing video, but i guess that's mostly shuffling data back and forth21:26
freemangordonkerio: it will compile, but it won't work21:27
keriowhy? :o21:27
freemangordonbecause of things like signal/exception handling and generation. MPU/FPU context, etc,etc21:28
keriohm21:30
keriowell, it's time we got an up-to-date kernel anyway ;)21:30
freemangordonwell, I agree, when are you going to release it?21:30
keriotomorrow21:31
kerioif nothing else comes up21:31
freemangordongood, i'll wait for it21:31
freemangordonShadowJK: it is your DSP that decodes it then :)21:32
freemangordonthough most of those those 20% are most probably used by PA, there is only one large memcpy happening - from GST_BUFFER to framebuffer21:34
ShadowJKi didnt think pa used any measurable amounts of sys21:46
* ShadowJK wonders if a2dp encoder is closed sauce21:47
kerioShadowJK: it is21:48
kerioin the sense that you can't recompile a physical chip21:48
keriountil 3d printers become much better, at least21:48
ShadowJKuh22:23
ShadowJKI thought the a2dp encoder was software22:23
ShadowJKsbc or whatever the codec is called22:23
keriothere's not much change in cpu usage between audio through cordful headphones and bt headphones22:25
ShadowJKoh? I've got like 40% use with bt headphones22:27
