| qi-bot | [commit] Werner Almesberger: ircstat/ML: update for 2/2013 (master) http://qi-hw.com/p/wernermisc/9d784c2 | 16:44 |
|---|---|---|
| kyak | wow, they managed to fuck up wireless really bad in 3.8 | 17:06 |
| wpwrak | oh ? | 17:10 |
| kyak | starting from "capabilities/regulatory prevented using AP HT/VHT configuration, downgraded" and ending with "fail to flush all tx fifo queues" | 17:10 |
| kyak | all kinds or weird messages, random deauth from AP, reboot helps and things like this | 17:11 |
| kyak | i'm wondering, do they have quality control at all? | 17:12 |
| kyak | like, some sort of regression testing at least?... | 17:12 |
| kyak | i still remember how my trivial patch didn't pass their weird "patch submission system?: | 17:13 |
| kyak | and still we see that other patches easily get in, and cause big problems | 17:14 |
| kyak | like, see, this one was supposed to fix some bug: https://patchwork.kernel.org/patch/2123681/ | 17:14 |
| kyak | it didn't take long before another fix for this fix had to be issued: http://comments.gmane.org/gmane.linux.kernel.wireless.general/104268 | 17:15 |
| kyak | "When the if statement is rewritten as 'if (A || B)', it turns out that A is | 17:17 |
| kyak | true, and B is false." | 17:17 |
| kyak | yeah, you have to teach kernel developers these things now :) | 17:17 |
| wpwrak | hmm :) | 17:36 |
| larsc | I'm innocent, I don't do wireless | 17:59 |
| larsc | speaking of bugs, wpwrak, can I blame all the vfat corrution I get on you? | 18:00 |
| wpwrak | only fat corruption :) | 18:10 |
| kyak | --) | 18:19 |
| kyak | wpwrak: btw, are there any plans do upgrade atusb do the latest kernel? | 18:20 |
| kyak | for what i've tried, it compiles and loads on 3.7 and 3.8, but doesn't work | 18:20 |
| kyak | and also kernel panics sometimes :) | 18:20 |
| kyak | i've packaged the atusb module and lowpan-tools for arch linux, and it was not so hard (i had to push some config options in default kernel config for arch, which were not there) | 18:21 |
| kyak | but the problem is that at the moment it's all for nothing -\ | 18:22 |
| wpwrak | yeah, i have that in my queue. actually to rewrite the driver and do more processing on the device itself (to avoid those expensive usb round-trips) | 18:25 |
| kyak | wpwrak: sounds great! | 18:28 |
| kyak | wait a minute.. usb? | 18:28 |
| kyak | ah.. sorry :) | 18:28 |
| wpwrak | did you mean atben ? | 18:53 |
| whitequark | wpwrak: (cpld or small fpga between cpu and 8:10 card(s)) PSoC? | 20:40 |
| larsc | still trying to pitch that one? | 20:47 |
| whitequark | larsc: hm? I don't even own a board | 20:48 |
| larsc | just kiding, but you seem to bring it up every now and then | 20:48 |
| larsc | which I dont mind | 20:49 |
| whitequark | well I did try to bring it up once | 20:49 |
| whitequark | there was a neat kickstarter | 20:49 |
| whitequark | then I noticed a windows-only IDE or so and became disgusted | 20:50 |
| larsc | unrelated. btw. https://www.coursera.org/course/vlsicad just started | 20:51 |
| wpwrak | whitequark: naw, too little cpld in these. and you don't need the core. | 20:51 |
| larsc | might be interesting for some people in here | 20:52 |
| wpwrak | larsc: i actually like the concept of psoc. and they got more open-friendly with time. but there are issues, too ... | 20:52 |
| whitequark | well didn't they always have docs on bitstream? | 20:53 |
| whitequark | but then xilinx also does that | 20:53 |
| wpwrak | psoc don't have a bitstream. they have (had ?) docs with all the registers. (that do the equivalent of the bitstream) | 20:57 |
| wpwrak | and the issues i mean aren't so much about openness but more about tininess and the things that come with it | 20:58 |
| roh | hm... ive seen those in the ebike controllers we use | 20:58 |
| wpwrak | alas, they're a rather non-ideal candidate for joining forces among the downtrodden, because they also firmly believe in windows | 20:59 |
| roh | yeah. there they are abused as a 3phase bldc brushless controller ,) thats about what one wants to do with em | 20:59 |
| larsc | haha, "solving a 40 variables boolean equation with karnaugh maps takes 1,099,511,627,776 squares... there has to be a better way' | 21:06 |
| wpwrak | it helps a lot if you already know the solution :) | 21:09 |
| larsc | which makes you wonder why the hell they let you solve hundreds of kmaps in university by hand, yet they never have more than a handful of variables, which doesn't really have any practical applications | 21:09 |
| wpwrak | well .. perhaps to understand the structure ? | 21:09 |
| wpwrak | but yes, "hundred" seems a little excessive. i don't think i ever encountered more than perhaps "tens" | 21:09 |
| larsc | I might be exaggerating | 21:11 |
| larsc | but i met them in both CS and EE | 21:11 |
| wpwrak | the two tend to overlap :) | 21:23 |
| larsc | wpwrak: it's a bit as if they thought you addition that only works for numbers between 1 and 99 | 21:26 |
