wpwrakaww, indeed. i *knew* something was wrong ...00:54
DocScrutinizer05any tips how to re,ove crumbs and debris out of a laptop style keyboard?01:14
DocScrutinizer05almost seems like I had to pull all the keycaps first - or at least half of them01:16
whitequarkDocScrutinizer05: yes, you do01:19
whitequarkthere is a special tool for removing keycaps01:19
DocScrutinizer05dang, thought sth like this01:19
whitequarkyou can make it yourself with um. two bent wires and a piece of wood01:19
whitequarkbasically you need two wire loops that go under the keycap and grab it from four points01:20
whitequarkand then something to pull on it relatively evenly01:20
whitequarkit is a very simple tool01:20
DocScrutinizer05mhm, can do that01:20
whitequarkthey sell it for $6 on amazon :D01:21
Action: DocScrutinizer05 regrets not playing guitar01:22
whitequarkI think you really need to use some kind of powerful air stream to clean it up01:22
whitequarkafter removing the keycaps even01:22
whitequarkcanned air won't cut it01:22
whitequark(I tried)01:22
whitequarkand for the keycaps themselves, throw them into an ultrasonic cleaner filled with isopropanol or something. I would do that01:22
whitequarkin fact I'd throw the whole keyboard there but it likely won't fit. unless you have a really big cleaner01:23
Action: whitequark sighs01:24
whitequarklet's give freecad another try. I wonder if it stopped randomly segfaulting yet.01:24
DocScrutinizer05or maybe I go lazy: http://www.amazon.de/gp/product/B001PMRB1S/sr=8-1/qid=1404437105/ref=olp_product_details?ie=UTF8&me=&qid=1404437105&sr=8-101:26
DocScrutinizer05M, N and B already lost the paint of printing anyway01:27
whitequarkas if you need to look at the key to know that it's there01:27
DocScrutinizer05not really, as long as it's only M and N ;-)01:28
whitequarkdo you really look at the keyboard while typing?01:29
whitequarkI don't even *have* the russian layout on this laptop and I don't think I have ever noticed it01:29
DocScrutinizer05actzally I developed a strange love to this slowly vanishing paoint - maybe it forces me to learn proper blind typing shortly before retirement01:29
whitequarkcould certainly go with all-black keycaps with no difference01:29
whitequarkI don't believe you're going to retire :p01:30
DocScrutinizer05sure, I might die before ;-P01:30
DocScrutinizer05otherwise in a few decades it's inevitable01:31
whitequarkyou really want to sit around and do absolutely nothing?01:31
whitequarkisn't that... boring?01:31
DocScrutinizer05err, right now I don't have any such plans01:31
DocScrutinizer05I bought 3 Tritium keyrings only 4 years ago, and I still plan to see themn fade away ;-D01:33
whitequarkwait, didn't they forbid to import that stuff?01:33
DocScrutinizer05import, yes01:34
DocScrutinizer05possess, no01:34
DocScrutinizer05in GB they are still freely available, I think01:36
DocScrutinizer05In Russia they probably still use Radium, eh? ;-D01:37
whitequarkyou can find radium ink rather easily in garbage still01:37
whitequarkor at least that's what I'm told01:37
whitequarkwell, easily considering how old it 01:37
DocScrutinizer05easily thanks to how easy it is to find it ;-P01:38
DocScrutinizer05when there's one thing that's easy to find in a giant landfill when you're searching for it, then that's probably Radium ink01:39
DocScrutinizer05you just need to steer clear of the discarded gamma ray sterilizers01:39
whitequarkthat's for sure01:39
DocScrutinizer05but I heard they recycle those directly in steel ovens01:40
DocScrutinizer05gives the steel a lovely warm touch ;-)01:40
whitequarkI never heard of it being done deliberately01:41
whitequarkbut accidentally, yes, there's a small but continuous stream of incidents.01:41
DocScrutinizer05nah, just because the Cobalt60 can looks like any other steel junk01:41
whitequarkscrap yards must have geiger counters in exhaust for this purpose01:41
whitequarkthough this only detects it and doesn't really prevent fallout in some nearby city01:42
DocScrutinizer05haha, yeah I bet they are all in perfectly working condition01:42
DocScrutinizer05"that damn thing again started beeping. Third time today. Pavel, take the hammer and fix it!"01:43
DocScrutinizer05it's really nasty when they melt it together with 500t of other steel scrap01:44
DocScrutinizer05might just reduce the radiation level so it doesn't instantly kill01:45
DocScrutinizer05actually I only "recently" learned they use that stuff in hospitals too (though not *that* brute power). I thought it's only used in sterilizers, large concrete building/machine where you send in vegetables or medical tools or whatever at one end and it comes out 3min later on the other end, totally sterile01:48
DocScrutinizer05I think the walls are more than 1m thick01:49
whitequarkhehehehe https://pbs.twimg.com/tweet_video/Brqd296CIAA9CBv.mp401:50
DocScrutinizer05and fixing such machine is probably a highly exciting job01:50
whitequarkwell, it has some kind of a hatch that closes the box01:50
whitequarkthen you're only left with (hopefully low) level of induced radiation01:51
DocScrutinizer05sorry, dunno but mp4 and similar stuff doesn't play in my PC01:51
whitequark$ vlc http://url.mp4?01:51
DocScrutinizer05seems I "forgot" to install vlc01:52
DocScrutinizer05oops, nope. wrong shell01:52
DocScrutinizer05[0x7fdb6c0009b8] main input error: no suitable demux module for `https/://pbs.twimg.com/tweet_video/Brqd296CIAA9CBv.mp4'01:54
whitequark> https/://01:55
whitequarkthat's not an url01:55
DocScrutinizer05mot my idea01:55
whitequarkput it in quotes? seems your shell screwed it up01:55
DocScrutinizer05jr@saturn:~> vlc https://pbs.twimg.com/tweet_video/Brqd296CIAA9CBv.mp401:55
DocScrutinizer05putting it in quote doesn't change much, though a lil bit. It doesn't complain about demux anymore, it just simply doesn't play it01:57
DocScrutinizer05or ... how to put it ... plays it in 0.1s01:58
DocScrutinizer05according to timecode. No visible video content though01:58
whitequarkfuck, it segfaulted02:34
whitequarkamazing, now it segfaulted AND corrupted my data.03:03
whitequarkwhat a piece of shit.03:03
wpwrakit would be lovely if someone would take the concept of fped and turn it into 3D, or at least proper 2.5D. i'm using it as 2.5D, but in a very crude way.04:58
wpwrakand of course, fped isn't really meant to be a cad system, though i keep on coming back to it because the rest just sucks so badly04:59
whitequarkwell, from my POV, fped sucks just as badly05:00
wpwrakfreecad shows a lot of promise and i think the constraint solver is a very nice concept, but then the step from 2D to 3D seems to be missing.05:00
wpwrakyou tried it ?05:00
whitequarkI looked at it05:00
whitequarkand yeh, tried a bit05:00
whitequarkit's not any more pleasant to use than freecad, I guess, if you're not its developer05:01
wpwrakwell, a few people have used it and liked it :)05:01
wpwrakif has a bit of a learning barrier, but that can't be a problem in your case05:02
wpwrakjust to be clear: because it's not a "real" cad system, some things don't work well for cad tasks. so for them you can't use the gui. for example, handling of arcs in rounded boxes, which is a common scenario for cad.05:04
wpwrakfor footprints, such structures don't exist. so it's not a problem there.05:05
whitequarkI don't see it being any less frustrating to use than freecad, if for different reasons05:05
whitequarktherefore, there is no effective difference05:05
wpwrakalso in 2D ?05:06
whitequarkI don't have any pure 2D tasks...05:06
whitequarkat least, I don't need a CAD for one05:06
wpwrakah :) fped is designed for 2D, but i'm forcing it to do 2.5D05:07
wpwrakand even the 2D is quite restricted - to what you need for footprints. no point in supporting advanced geometry if all you can possibly do with it is to get things wrong (since none of this is used in footprint definitions)05:08
apeletelarsc: still having issues with 3.16-rc3, "Unhandled kernel unaligned access"07:25
apeletelooks like some kind of memory corruption, but I can't inspect the content of musb->xceiv with gdb (maybe because of some kind of optimization)07:26
Action: whitequark has machined some aluminium07:27
apeletelarsc: tried to recompile musb_init_controller() with __attribute__((optimize("O0"))) but it didn't help, looks like I'm stuck right now :-(07:28
apeletelarsc: do you have any idea that may help ?07:29
apeletelarsc: last night I was thinking about git bisecting to narrow down possible causes07:30
apeletewill probably take a lot of time, and not sure it'll help07:31
larscgit log v3.14..v3.15 drivers/usb/musb07:34
larscnot that many changes07:34
apeleteok, so that would be between v3.15 and v3.16-rcX07:37
larscah, you are trying v3.1607:38
apeletelarsc: holy cow, felipe changed the name of the nop transceiver driver in the first commit of that range07:42
apeletelast night I was thinking about "what would be the impact of the xceiver driver name having changed" :)07:43
apeletebut then I thought "it would probably brake the build of a lot of glue layers" and I forgot about it07:44
apeleteI'll try to change the name in jz4740 platform data and see if it solves the issue07:45
Action: apelete wishes he could work on kernel stuff during daytime...07:50
larscduring the day he is a normal office drone, but at night he turns into KERNELMAN!07:50
larscnot the driver developer we deserve, but the driver developer we need07:51
larscoh, the other way around07:52
apeletemaybe I should turn into a superhero, at least they do their stuff during the day07:53
apeleteand they can still continue into the night if they wish07:54
apeleteand I don't even talk about the benefit of wearing their pants ON TOP of their trousers07:57
nicksydneywpwrak: nice little solder paste dispenser http://letsmakerobots.com/content/solder-paste-dispenser13:07
wpwrak(solder dispenser) cute :)15:43
kristianpaulgermany 1 france 017:03
DocScrutinizer05well, as tool in a CNC it would be even more useful17:35
wpwrakmatch is getting dirtier ... in the first half, .fr did the fouls, now it's .de17:40
ysionneauit seems .de are doing quite a lot of faults17:41
wpwrakand nasty ones17:43
ysionneaubut I guess at this stage of the competition it's clever to grab yellow marks17:44
ysionneauas long as you don't get the red one17:44
wpwrakyellows get reset for the next match, so there's no risk of getting blocked just by yellows alone17:50
wpwrak(excluding yellow-red, of course)17:50
ysionneauah ok I didn't know about the reset17:50
ysionneauI wonder why French don't do more faults then17:50
wpwrakit took some searching :) http://en.wikipedia.org/wiki/Yellow_card_(association_football)#Post-match_penalties17:51
wpwrakfrance's last two minutes ....17:52
wpwrakneuer is incredible17:55
wpwrakmeh, but "man of the match" is hummels18:00
DocScrutinizer05sign at doo of a pub: "Neuer - France"18:01
wpwrakalready on the intertubes: http://pics.nase-bohren.de/neuer-frankreich.jpg18:06
DocScrutinizer05Last Neuer action  looked like handball keeper to me18:25
DocScrutinizer05cool dude18:25
DocScrutinizer05((<wpwrak> yellows get reset )) don't think so. NFC but one comment about "those three players are already biased and may not go too leete in this game..." made me think otherwise18:37
DocScrutinizer05aahyep wili also says "two yellow == one game penalty"18:41
DocScrutinizer05but seems they are reset on semi-finale18:42
DocScrutinizer05>>any player who received two yellow cards between the beginning of the tournament and the end of the quarterfinal round (instead of the end of the group stage matches) would serve a one-match suspension for the next game. As a result, only players that received two yellow cards or a straight red card in the semifinal game would not be able to play in the final.<<18:43
DocScrutinizer05but player who gather their 2 yellow up to quarter-finale (i.e. during today's match) would still get suspended for semi-finale?18:45
zrafafrance remembered to start to play the last minute of the match19:51
zrafakristianpaul: it is your turn, please play well :)19:51
wpwrakDocScrutinizer05: with yellow reset after quarter would be to have them both in semi, which means red. whcih would ban the player from the next match. so yes, in this sense it still applies.20:36
DocScrutinizer05nevertheless a player gathering his 2nd yellow in quarter is suspended for semi20:38
wpwrakah yes, that too. so messi has to be careful.20:44
wpwrakbad referee -> ugly play21:27
wpwrakkristianpaul: hmm, seems that champagne consumption in colombia will not be very large tonight21:29
wpwrakone more, please ! and then let the champagne flow :)21:40
DocScrutinizer05now those are fouls21:50
wpwrakfireworks :)21:57
