wpwraki'm not sure whether i got your real question in each case. so if i didn't answer it, please ask again (there or here)02:43
nicksydneywpwrak: was thinking are you planning to do a trial run of the board using service like seeedstudio ? 04:29
nicksydneybtw is the board 5x5 in size or more ? if it's 5x5cm it will cost $10 :)04:30
whitequarkI wonder how quickly (if at all) mail goes CN->AR04:30
nicksydneythis is awesome http://serverfault.com/questions/221337/logrotate-successful-original-file-goes-back-to-original-size05:07
nicksydneyno sorry this one05:07

nicksydneyGet Cypress PSoC 4 MCUs for $1 Delivered to Your Door by Fedex http://www.cnx-software.com/2014/06/04/get-cypress-psoc-4-mcus-for-1-delivered-to-your-door-by-fedex/12:08
nicksydneyOV965x (Camera) Breakout Board https://github.com/iabdalkader/OV965x12:15
wpwraknicksydney: the (combined) board is currently  30 x 66 mm. for installation, you'd cut it and make the two parts overlap by 2 mm, so the assembly is 30 x 64 mm and the case then 33 x 67 mm12:29
nicksydneywpwrak: bit confuse.....combined board ?12:32
wpwrakwhitequark: CN->AR is fairly quick. the problem now is what AR customs will let through. actually, i wish all the businesses that are suffering badly under this nonsense would get together, collect money for a capable assassin, and rid us of the one guy who's behind all this.12:32
nicksydneyCC2541 from taobao is cost 8yuan http://item.taobao.com/item.htm?spm=a230r.1.14.155.FGKXLR&id=37658686332&ns=1#detail while in Digikey it's cost $5 ..WTF !12:36
nicksydneyyou can get any kind of form factor for the PCB for CC2541 http://s.taobao.com/search?q=cc2541&commend=all&ssid=s5-e&search_type=mall&sourceId=tb.index&spm=a215z.7106357.5803581.d490851312:37
whitequarkwpwrak: thought it12:38
wpwraknicksydney: (seed) dunno. there are many pcb-making services. if it just want a few pcbs, it's probably easier to get them made locally. that is' unless i want to check the work of a specific fab for MP.12:41
wpwrak(cc2541) but we use cc2543 ;-)12:41
wpwrak(gist) let's see ...12:41
wpwrak(gist) answered :)12:58
nicksydneyhttp://techon.nikkeibp.co.jp/english/NEWS_EN/20140604/356165/  NHK Develops 133-Mpixel CMOS Sensor for 8k4k Video13:02
nicksydneywpwrak: thanks13:07
nicksydneywpwrak: i thought from TI website I read that CC2543 is not labelled as BLE so that's why I thought Anelok will not be using BLE :)13:08
nicksydneythat's why i was looking atound for CC2541 pricing13:09
wpwrakCC2543 isn't labeled as BTLE because the 2541, which is, runs their proprietary BT stack. the 2541 also has a few small modifications that should make processing BTLE much easier, but unfortunately, they're not documented. so we'll have to apply some workarounds in the 2543.13:11
wpwrakbut besides that, the chips are nearly identical13:11
nicksydneyso the 2543 is like blank slate to be uplaoded with BTLE stack ? :)13:15
wpwrakwell, a partial stack, it's probably too small for everything. but we'll see.13:17
nicksydneyit will be interesting if anelok one day can flash any kind of 2.4ghz stach that the user want to use for their own purpose :) 13:22
whitequarkthere's also modulation...13:22
wpwrakyou can flash whatever you want :) but yes, modulation choices are your principal enemy there13:23
nicksydneyanyone going here https://www.google.com/events/io ?13:23
nicksydneymodulation ?13:23
wpwrake.g., it couldn't do 802.15.4 since it doesn't understand that modulation13:24
wpwrakand there are a few more things like symbol mapping, whitening, even CRC. these things all happen basically at the bit level, so it's expensive (slow) to do them in software13:25
wpwrakand slowness can kill you if you have to turn around quickly to send an ACK or such13:25
wpwraktime to update gnutls, it has a server-attacks-client crash or even code execution bug: radare.today/technical-analysis-of-the-gnutls-hello-vulnerability/14:47
wpwrakjust when you thought heartbleed was bad ...14:47
whitequark"time to update gnutls" -_-14:48
whitequarkthat time was three days ago14:48
wpwraki mean, install the updated packages :)14:49
whitequarkGrammatical gender doesn't always correspond to real gender. The word [Ein Mädchen] came from "die Magd", which means "the maiden" (it's an old word now, and has medieval connotations), and it took the diminutive ending of -chen to get a meaning of "the girl" by becoming "das Mädchen". All words that take the diminutive ending of -chen are neutral. So the original word is feminine, but because this is a -chen diminutive of the original wor14:51
whitequarkand I thought english had a lot of corner cases -_-14:51
ysionneauI think it's a lost cause to search origin of gender of nouns14:54
ysionneauin French or German14:54
ysionneauyou just need to learn and that's it :/14:54
whitequarkthey tried to teach me French in school14:54
whitequarkdamn vowels, how do they even work. I refuse to even look at French ever since14:54
wpwrakwell, of the appropriate gender in appearance and grammar = it's okay to have sex. if there's a disagreement, don't do it. very nice and clear :)14:55
whitequarkwpwrak: ... I don't get it?14:55
wpwrakalso works for boys, though the diminutives are not very common in modern use. but the gender-independent word "kind' (child) is also neutral. so the indicator works there, too14:57
whitequarkthis is going to be the hardest part of the language14:59
larscyou basically need to remeber for each word whether to use der/die/das15:02
whitequark"ü no equivalent nor approximate sound in English" -_-'15:28
whitequarkoh, though, there is one in russian15:28
DocScrutinizer05"ü" is simple: say "you" and press your tongue against your lower front teeth for the "u"15:39
wpwrakwhitequark: northern english should have it :)15:42
DocScrutinizer05your rear tongue automatically will come up against your roof of mouth a bit. here yoü are15:42
wpwrakDocScrutinizer05: that's a *very* messy "ue" ;-))15:42
DocScrutinizer05for a lots of better ones, listen to turkish speaker! ;-)15:43
DocScrutinizer05haha, wikipedia quotes "Führer" as a commonly known and used word with ü15:47
whitequarkI guess it is?15:50
wpwrakit also appears in a very common document in german-speaking countries, the "Fuehrerschein"15:54
wpwraki guess they missed that one during denazification15:54
DocScrutinizer05there's also a short form e.g. Hütte15:58
whitequarkwpwrak: yeah, titles like Geschäftsfürher are funny15:59
DocScrutinizer05Names like Adolf are funny15:59
whitequarkespecially because "Geschäft" is made its way into russian, but with somewhat different meaning15:59
wpwrakbetter way to produce "ue": say "google" but make the "oo" very long. then, while still making the "oo" sound, move your tongue forward. when you touch the teeth, its has become an "ue"15:59
DocScrutinizer05so where's the massive diff between gOOgle and yOU ?16:00
wpwrakfewer variations by dialect ;-)16:01
ysionneauit seems all vowel sounds in german are also in french16:02
DocScrutinizer05you can't help but love how *nothing* in English is written like you speak it16:02
ysionneauI'm trying to learn German and they put equivalent french sounds in my book16:02
ysionneauand so far it's not so hard to pronounce16:03
wpwrakysionneau: no problem with "ue" for you then ;-)16:03
DocScrutinizer05I guess french has quitre sonme more than german16:03
wpwrakfr.u == de.ue16:03
DocScrutinizer05The French fail terribly e.g. in words starting with "h"16:03
ysionneauthe only thing is that I need to remember when "ch" needs to be pronounce "RRR" or "sh" kind of sound16:04
ysionneauand the g that get pronouced like k 16:04
ysionneauand d like t16:04
ysionneauDocScrutinizer05: because usually we just don't pronounce the 'h' ?16:04
ysionneauyep I agree16:04
ysionneaubecause in French is just not pronounced :/16:05
ysionneauI'm learning to take deep breath as well, in order to be able to pronounce german words till the end16:05
DocScrutinizer05yeah, you're not used to taking breath in between a sentence ;-)16:06
wpwrakand then you have tortured constructions like "qu'est-ce que c'est" ...16:06
ysionneauand ä ö ü stuff usually I hesitate on how to pronounce16:06
ysionneauwpwrak: ah yes :p sounds natural to me though, but then when learning foreign language it's funny to see the equivalent of this kind of construction16:07
DocScrutinizer05ä = affaire16:07
ysionneauWas ist das?16:07
wpwraki prefer :) "c'est quoi ?"16:07
DocScrutinizer05ö = peut etre16:07
ysionneauö == eu ?16:08
DocScrutinizer05ü = la nUIt16:08
ysionneauah and the 'e' which sometimes is pronounced é or è or EU16:08
DocScrutinizer05well nUit16:08
ysionneaulike den or denn 16:08
DocScrutinizer05yep, that's a hard one16:09
wpwrakor quatre-vingt-dix-neuf (4 * 20 + 10 + 9 = 99, indeed). in switzerland, they had the sense to simplify it to "nonante-neuf"16:09
ysionneauwpwrak: in German it's funny the fact that you put the unit in first position16:09
ysionneaulike 32 is 2 3016:10
ysionneaubut then 132 is not 2 30 10016:10
ysionneauit's 100 2 30 or something16:10
DocScrutinizer05exactly, einhundert zwei und dreissig16:10
ysionneauusually it's written with space or all together?16:11
ysionneauin my book they put numbers all attached16:11
ysionneauunreadable :(16:11
DocScrutinizer05I think usually nobody writes it16:11
wpwrakyeah, the concept worked well for two digits. but then the village grew and they needed to add "extended numbers". a bit like "extended memory" in older PCs16:11
DocScrutinizer05except on money checks where "in words:"16:11
ysionneauah yes16:12
ysionneauyou've got big checks then?16:12
DocScrutinizer05and there it's usually --eins--drei--zwo--16:12
Action: ysionneau kidding16:12
DocScrutinizer05oooh, fünf (5) has a nice ü16:13
ysionneauso it seems äü are just pronounced like they would be in french without the ¨16:14
ysionneauand ö16:14
ysionneauah no ö16:14
ysionneaubut the two others yes16:14
DocScrutinizer05böse -> peut se16:17
DocScrutinizer05böse -> peut c,e16:17
DocScrutinizer05sorry no cedile16:17
whitequark<Multi_key> <c> <,> ?16:18
ysionneaulike in mögen?16:19
DocScrutinizer05ä = maison16:20
ysionneauah then it's like "è" or almost16:21
ysionneauok so I've got it almost all wrong :D16:22
DocScrutinizer05even a native german speaker can't distinguish between hätte and hette16:23
wpwrakand it easily turns into "a"16:23
wpwrakwell, "er"16:24
wpwrakfirst day in school, they wrote out names on little cards. i couldn't find mine because i was looking for "werna"16:24
ysionneauI found it funny my book tells me to pronounce "a" (french "a") for some 'r'16:25
ysionneaubut in the end it works well16:25
wpwrak(austrian pronounciation)16:25
ysionneaulike "der" -> pronouncing "dea"16:25
DocScrutinizer05yep, that's kinda correct16:26
ysionneauoff I go , see you16:26
Action: DocScrutinizer05 too16:26
wpwraknow this sounds VERY interesting: https://www.seedmatch.de/  note: crowd_investing_17:11
wpwrakthe only problem: limited to german investors17:15
