nicksydneyA Guy In China Built A Remarkably Accurate Copy Of The Batmobile [PHOTOS] http://www.businessinsider.com.au/china-batmobile-replica-2014-601:11
nicksydneyonly in China :)01:12
wpwrakhmm, he should have used matte paint. too many highlights01:15
nicksydneynow it's a matter of time before this will appear on eBay with FREE shipping :)01:17
wpwrakFOB somewhere in the hinterlands of china01:19
nicksydneytax free :)01:24
nicksydneyone day hopefully for me this http://makezine.com/2014/06/02/our-living-room-is-now-a-family-workshop/01:24
nicksydneyonce i have my own place :)01:24
wpwrakyou mean after kicking out wife and kids ? :)01:28
nicksydneywpwrak: hahahaaa.....before i do that they will kick me out :)01:57
wpwrakDocScrutinizer05: btw, here are the schematics: http://downloads.qi-hardware.com/people/werner/anelok/tmp/anelok-20140601.pdf04:11
DocScrutinizer05uh, NC04:14
DocScrutinizer05100uF, what you're using?04:14
wpwrakflat ones :)04:15
wpwraki only have 1 mm04:15
wpwrakwell, a bit of wiggle room. but not a lot.04:15
DocScrutinizer05you're puzzling me, U3 table on page 2, but no U304:17
wpwrakactually ... i should move them a bit since they're too tall. better than the huge 220 uF i had first, but 1.8 mm is still too much. it's these: www.digikey.com/product-search/en?vendor=0&keywords=399-5620-1-ND04:18
wpwrakah yes, s/U3/U2/ :)04:19
DocScrutinizer05C13 is either 4u7 or 10u on table, but 1u on page3. And I doubt you'll change that one accordng to some U304:20
wpwrakor no, i don't have to move 'em. they're already at a safe spot.04:20
wpwrakah, i see what happened. i renumbered but forgot to update the table :(04:21
DocScrutinizer05C9, C18, C27. fun!04:21
Action: DocScrutinizer05 waits for C3604:22
wpwrakdidn't want to renumber AGAIN ;-)04:22
DocScrutinizer05suggestion: number all components on sheet 1 like 100, 101 etc, generally 100+N. On page 2 200+N and so on04:23
wpwraki tried that but didn't like the enormous numbers04:24
DocScrutinizer05it#s awesome, no searching, no renumbering04:25
wpwrakmaybe in a future version, when i add a dozen more components or so :)04:26
DocScrutinizer05goes a looong way to make stuff easier and clear to see04:26
DocScrutinizer05you can even tell from BOM which components belong together04:26
DocScrutinizer05I guess you never coded BASIC with a silly interpreter that needed line numbers, eh? ;-)04:28
wpwrakoh, i did. and RENUM wasn't the most reliable command ...04:29
DocScrutinizer05the better ones of those critters came with a renumber(range, new-start-number, increment) command04:30
wpwrakthere's no language too basic to not get referential integrity wrong ...04:30
wpwrakyes. and sometimes it was subtly broken :)04:31
DocScrutinizer05oh dear, those were the times...04:31
wpwraki still fondly remember the 3-pass pascal compiler. pascal/z i think. you learned the true meaning of patience in those days ...04:33
DocScrutinizer05"WUT? Too slow? you b***ard! Here take those hex codes instead of your crappy basic!"04:33
DocScrutinizer05I knew complete Z80 opcodes by heart back when04:34
wpwraki don't think i reached the terminal stage of that04:35
DocScrutinizer050xC3 must be a jump, 0xCD a subroutine call, and 0xC9 a return04:35
DocScrutinizer05DJNZ, awesome04:36
DocScrutinizer05felt lke 3rd generation ;-P04:36
wpwrakbut wasn't NOP 0x90 .. ah no, that's already x8604:36
wpwrakindeed. very cisc :)04:36
DocScrutinizer05we all frowned at 8088 back when. It been generally attributed as being braindead04:38
DocScrutinizer05segment register dressing, OMG!04:38
wpwrakit's funny to find the 8088 mentioned in an 8080 manual :)04:39
DocScrutinizer058086, 8088, I can't even recall what's been the diff04:40
DocScrutinizer05the 8086 been 16bit or sth?04:40
DocScrutinizer05even maybe 24bit addr bus?04:40
wpwrak8088 and 8086 are the same except for the bus width. 16 bit, both. 8088 had an 8 bit data bus.04:41
DocScrutinizer05aaah yes04:41
DocScrutinizer05right, the double fetches04:42
DocScrutinizer05Zilog also built a successor of Z80, can't recall the name. Maybe Z800 or Z800004:43
DocScrutinizer05http://de.wikipedia.org/wiki/8088#Verwendung has it to the point04:46
nicksydneyreading DocScrutinizer05 and wpwrak feels like 2 old mates who were separated apart during World War 2 :)05:34
DocScrutinizer05well, it was OM-war 105:35
nicksydneysounds pre-historic :)05:40
nicksydneywpwrak: have you ever used busybox ?07:00
nicksydneytrying to make sense the syslogd inside busybox07:00
kyakwhat's with syslogd?07:02
nicksydneykyak: tried configuring it to read kernel logs but can't seem to work .. is it possible to use it to read kernel logs ? like how dmesg is doing ? planning to use syslogd to do log rotation for the kernel logs (busybox syslogd)07:03
kyaknicksydney: i'm not sure.. in openwrt, syslogd handles messages from system (which you can read with logread). Kernel logs are left for dmesg07:30
nicksydneykyak: hmmmm.....maybe syslogd in busybox is different than the standard Linux syslogd i presume07:30
nicksydneyDocScrutinizer05: in busybox it's called syslogd .. no ksyslogd07:31
kyaknicksydney: it sure is.. syslogd is just a part of busybox binary07:31
DocScrutinizer05I for the life of mine couldn't figure how busybox provides syslogd07:31
nicksydneyDocScrutinizer05: from the code i read it open an xsocket to /dev/syslog and wait for some incoming...but when tried to use echo or cat'ing to it ..doesn't work..throws an error07:32
kyaknicksydney: http://wiki.openwrt.org/doc/howto/log.essentials07:32
kyakit seems that klogd may help07:32
DocScrutinizer05I'd for sure rather use proper syslog-ng instead of that messybox crap07:32
nicksydneykyak: klogd doesn't do file rotating07:33
kyakon small capability devices you often can't use "proper"07:33
DocScrutinizer05neither does syslogd07:33
DocScrutinizer05IroN900:~# ll `which syslogd`07:34
DocScrutinizer05-rwxr-xr-x 1 root root 27360 2009-08-17 12:02 /sbin/syslogd07:34
DocScrutinizer05_not_ integrated into busybox, despite it's a 100% busybox based system07:35
DocScrutinizer05IroN900:~# ll `which busybox`07:35
DocScrutinizer05-rwxr-xr-x 1 root root 355592 2012-08-24 19:20 /bin/busybox07:35
nicksydneyDocScrutinizer05: so it's ARM compiled ? using glibc ? 07:36
DocScrutinizer0527k for the real thing vs 355k for messybox. Sure it's not directly comparable to memory footprint and resource demand07:36
kyakDocScrutinizer05: and now ls -la /sbin/syslogd07:37
kyak/sbin/syslogd -> ../bin/busybox07:37
DocScrutinizer05I'm not a fool07:37
DocScrutinizer05IroN900:~# ls -la /sbin/syslogd07:37
DocScrutinizer05-rwxr-xr-x 1 root root 27360 2009-08-17 12:02 /sbin/syslogd07:37
kyakyou surely are not :)07:38
DocScrutinizer05btw you should see from missing "l" and "-" instead07:39
DocScrutinizer05resp -rwxr-xr-x07:39
DocScrutinizer05michael_lee: sure07:40
DocScrutinizer05nicksydney: sure07:41
nicksydneyi need to use busybox because it's part of Android so need to use something that can be compiled with bionic07:41
DocScrutinizer05IroN900:~# file /sbin/syslogd07:41
DocScrutinizer05/sbin/syslogd: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.14, dynamically linked (uses shared libs), stripped07:41
DocScrutinizer05sorry, when i hear "android" I skip to anothr channel07:43
nicksydneyDocScrutinizer05: haahha....i figure as much :)07:44
nicksydneyDocScrutinizer05: can't help it ..it keeps life chugging along :)07:45
kyaklet's see how long is the effect of word "android" on DocScrutinizer05 &08:05
kyakoh no, i just reset the timer :)08:05
nicksydneyAllWinner A33 Quad Core SoC is Pin-to-Pin Compatible with AllWinner A23 - http://www.cnx-software.com/2014/06/03/allwinner-a33-quad-core-soc-is-pin-to-pin-compatible-with-allwinner-a23/10:31
nicksydneyit's cool that ARM SoC from China always comes out with pin-to-pin compatible10:31
nicksydneyUS / Europe SoC player must learn and apply to their product make it easier for OEM :)10:32
wpwrak(busybox) who hasn't ? :)10:32
wpwraknewsflasgh: Allwinner releases new A11, pin-to-pin compatible to PDP-11 :)10:35
nicksydneywpwrak: (PDP-11) they skip that generation :010:37
nicksydneythere are the new millenia10:37
nicksydney9 Year Old Girl Lands 540! - https://www.youtube.com/watch?v=mD_yjW64buU ... let's see who can beat her :)10:38
nicksydneyCavium Thunder X ups the ARM core count to 48 on a single chip -- http://semiaccurate.com/2014/06/03/cavium-thunder-x-ups-arm-core-count-48-single-chip/ ... WHAT !???10:39
wpwraksigh, is it coremania time again ?10:40
wpwrakfirst the GHz race, now coremania ...10:40
nicksydneywpwrak: seems like it...too many cores and not enough Linux :)10:40
wpwrakthen you have one core run "flunky hen" while the rest are busy executing sophisticated ultra deep sleep-power-down code ...10:42
nicksydneywpwrak: this is how i feel when i did my first PCB etching https://www.youtube.com/watch?feature=player_embedded&v=CLPG15HXkv8 :)10:42
wpwraklet's make that "fluffy beak"10:43
larscthat's probably a server chip10:43
nicksydneywpwrak: oh c'mon....can't be that bad...perhaps few cores running Android :) 10:43
Action: nicksydney counting timer to see if DocScrutinizer05 going to run or chime in :)10:44
nicksydneyNew Chip to Bring Holograms to Smartphones  http://online.wsj.com/news/article_email/new-chip-to-bring-holograms-to-smartphones-1401752938-lMyQjAxMTA0MDAwMjEwNDIyWj10:46
wpwrakthat look at 00:01:38 ;-)10:47
nicksydneydamn didn't know there is such thing as colourful snake...just blow me away https://www.youtube.com/watch?v=sPSFYGdoQyc10:49
nicksydney California Red-Sided Garter Snake 10:49
nicksydney How much do Y Combinator founders earn?  http://80000hours.org/blog/341-how-much-do-y-combinator-founders-earn ... i guess i'm worth only $1000...how much you are worth  ? :)10:51
larscif you have healthy kindeys and stuff I think we can find a better offer for you11:20
nicksydneyI don't understand iOS people think that "Terrific to see the Extensions API so that apps can finally talk to each other." is such a great thing.....perhaps they have not heard about Linux :)11:20
ysionneauAndroid has that since the beginning, that's crazy11:27
nicksydneyysionneau: true !11:27
ysionneau(intent system)11:28
nicksydneywpwrak: http://www.digikey.com/product-detail/en/XC7V2000T-G2FLG1925E/XC7V2000T-G2FLG1925E-ND/3981901 $39,452 for a FPGA !11:30
nicksydneyysionneau: oh well iOS people are spoilt brat anyway they won't listen or compromise !11:31
wpwrakdamn. standard package 1 unit ? no reels ?11:36
ysionneauI wonder what's so special with this fpga11:47
ysionneaunumber of RAM or CLB are not so high11:47
ysionneauis it the IO number?11:47
ysionneau1200 balls seems high number11:47
nicksydneyinteresting to see how many layers PCB is needed to completely route all the pins...my guess is 8 or 12 layers :)11:54
sb0ysionneau, it's basically for people who have a lot of money. US military, NSA & telcos.12:16
sb0ysionneau, the cost per CLB ratio in virtex/spartan is much higher than the virtex/spartan performance ratio (in other words: virtex is still slow). they are just targeted at different markets...12:17
ysionneauso Virtex is not that much better12:21
ysionneaubut it's really crazily more expensive12:21
nicksydneyhttp://newsroom.intel.com/community/intel_newsroom/blog/2014/06/02/intel-president-integrated-smart-connected-devices-fuel-next-era-of-computing - 130 new Intel-based Android and Windows tablets are debuting in the market from global OEMs and ODMs this year, and more than a dozen are launching during the Computex timeframe.12:23
nicksydneydon't know should be happy, excited, sad or cry ?12:23
sb0it's like first class seats on planes. costs 3x-20x the price of an economy ticket, but the flight is still slow and to a few exceptions (like beds) not that much more comfortable12:24
sb0(and yes, flights are slow. the concorde went in the right direction, but unfortunately was stopped)12:24
sb0airlines puts the costs of flying the plane into a few customers, xilinx pretty much does the same with the virtex series12:26
sb0*most of the cost12:26
wpwrakbtw, if anyone (nicksydney ? :) want to review the latest anelok schematics, they're here: http://downloads.qi-hardware.com/people/werner/anelok/tmp/anelok-20140603.pdf17:55
kristian1aulwhere os the diff??!! ;)18:45
wpwrakkristianpaul: yeah, sorry. since nobody is maintaining the command-line options anymore, we lost schematics differences :-(19:17
Action: wpwrak looks in the general direction of wolfspraul 19:17
wpwrakkickstarter getting a bit more of a beating: www.gizmodo.co.uk/2014/06/kickstarter-just-opened-the-floodgates-t%20o-even-more-frauds-and-scams/19:40
larscget rich quick, now is your chance19:54
whitequarksb0: I thought airlines got most of their cash from cargo19:55
larscon passenger flights?19:56
whitequarkin general19:57
larscI think what sb0 was trying to say that if everybody flew econemy they'd loose money on those flights19:58
DocScrutinizer05lol, time to go kickstarter with pink Neo90021:38
dos1"Kickstarter Just Opened the Floodgates to Even More Frauds and Scams" -> "time to go kickstarter with pink Neo900"21:52
dos1sounds worrying :P21:53
wpwraki think we should mention the levitation sensor that detects the presence of antigravity fields22:01
