2012-09-26 03:46 <wpwrak> smart people (i.e., those who use static content) don't fear /. :-)
2012-09-26 03:50 <whitequark> wpwrak: exactly
2012-09-26 03:50 <whitequark> pabs3: yeah, I monitor referers
2012-09-26 03:51 <whitequark> IMO, FPGAs are more like ASIC processes. They can and will be patented themselves, but after it's done, it does not affect you or your design, and you're not locked in to a particular chip.
2012-09-26 03:55 <whitequark> wpwrak: actually... do you ever sleep at all?!

2012-09-26 04:59 <wpwrak> whitequark: what for ? :)
2012-09-26 05:12 jekhor has joined #qi-hardware
2012-09-26 05:33 <wpwrak> well, truth be told, i tend to sleep quite a lot. but in an irregular pattern and often just a few hours at a time.
2012-09-26 05:55 <whitequark> wpwrak: I once read a blog of man who has tried a specific pattern of sleeping for 80 days or so
2012-09-26 05:55 <whitequark> he slept the usual 8 hours or so a day, but in small intervals
2012-09-26 05:55 <whitequark> i.e. 2-4-2-4-2-4-2-4
2012-09-26 05:56 <whitequark> there is some evidence that sleeping like that improves productivity significantly
2012-09-26 05:56 <wpwrak> yeah, that's somewhat close to what i do. but without pattern. i just sleep when i feel tired.
2012-09-26 05:56 <whitequark> he kind of confirmed that, but after those 80 days he quit because his wife was objecting
2012-09-26 05:56 <wpwrak> yeah, environmental acceptance is a bit of an issue ;-)
2012-09-26 05:56 <whitequark> well, I did that as well for months, on and off, but there are some problems I'd say
2012-09-26 05:56 <whitequark> (env acceptance) hehe
2012-09-26 05:57 <whitequark> first, most (if not all) employers aren't satisfied with that
2012-09-26 05:57 <whitequark> so, until I could completely dedicate my time for my own company... probably no luck with that
2012-09-26 05:58 <wpwrak> yeah, you need to be your own master for this kind of thing. or be really far from your boss.
2012-09-26 05:59 <whitequark> second, shops. this is especially painful if you're too lazy to cook for yourself, which I only recently overcame, but applies globally. night-time delivery and 24h shops help, but there are very few instances of both
2012-09-26 05:59 <whitequark> (for some reason I tend to be awake mostly at night with this pattern, or at least awake and bored enough to care about something which is not my work)
2012-09-26 06:00 <whitequark> (far from boss) well, our company has people working from Thailand and different eastern parts of Russia. here the problem is mainly the irregularity.
2012-09-26 06:01 <whitequark> third, you're caught in this stupid fragile body which has hormones, and if I'm only awake at night I tend to slip into quite a depressed state, which doesn't help much either.
2012-09-26 06:14 <wpwrak> nighttime is generally best for work that requires concentration. less disturbances.

2012-09-26 06:15 <wpwrak> dunno if there's a strong link between nocturnal activity and depression. maybe it amplified other factors, though.
2012-09-26 06:16 <wpwrak> and yes, shops are a problem, particularly if you throw procrastination into the mix :)
2012-09-26 06:19 kristoffer has joined #qi-hardware
2012-09-26 06:29 <whitequark> wpwrak: I wonder why is it so for nighttime (less disturbances)
2012-09-26 06:30 <whitequark> that is, I find that to be the case too, but as my online activity includes a lot of overseas people, it's not that I distracted less by IRC or something
2012-09-26 06:31 <whitequark> it is a little bit quieter overall, but I doubt that difference between 30dB and 40dB (or something like that) actually helps that much
2012-09-26 06:31 <wpwrak> during daytime, you can get many interruptions, telemarketing, postal service, neighbours ringing your doorbell, people calling the wrong number, and so on.
2012-09-26 06:32 <wpwrak> at night, all these are usually asleep and don't bother you.
2012-09-26 06:32 <whitequark> oh, I almost never get those. telemarketing, ewww. that's why I don't have a landline phone.
2012-09-26 06:33 <wpwrak> and yes, the ambient noise level surely makes a difference. your rodent brain feels safer if it's quiet and you could hear any predators from very far :)
2012-09-26 06:33 <wpwrak> getting rid of landline helps a lot, agreed
2012-09-26 06:33 <whitequark> (as per postal service, I'd be happy if those bastards actually ringed my door. but no, they prefer to slack off and make me walk all the way to the postal building, sigh)
2012-09-26 06:34 <whitequark> (rodent brain) makes sense. I'm definitely much more comfortable in a very quiet environment
2012-09-26 06:34 <wpwrak> another factor may be that there are fewer activity choices at night. so you can focus better on the few(er) things available for doing.
2012-09-26 06:35 <whitequark> agreed

2012-09-26 10:09 <whitequark> lekernel: talking about moronic comments
2012-09-26 10:10 <whitequark> once I shared a snippet on russian site with a name roughly translated as "shittycode.ru" [govnokod.ru]
2012-09-26 10:11 <whitequark> the snippet was an excerpt from Ingenic kernel source with a comment, you might have seen it, // No risk no fun, run with interrupts on!
2012-09-26 10:11 <whitequark> the rating of the snippet instantly plunged to -20 or so
2012-09-26 10:12 <whitequark> guess how was that motivated? "That's quite good piece of code, it has COMMENTS IN IT [emph. mine]"
2012-09-26 10:13 <whitequark> they were actually serious about that.

2012-09-26 14:19 <xiangfu> wpwrak, I finish the code on read the xc6slx9 configure register out. but the document confused me.
2012-09-26 14:20 <xiangfu> wpwrak, if you have time. please take a quick look at ug380.pdf Page:116.
2012-09-26 14:21 <xiangfu> [Shift configuration packets into the CFG_IN data register, MSB first.]. it says [159 Clocks(TCK)]. the correct value should be 111. right? (16 * 7 - 1 = 111)
2012-09-26 14:32 <wpwrak> hmm, i never really programmed low-level JTAG, so i'm not sure. the other transfers seem to suggest between n-1 and n TCK for n bits, yes.
2012-09-26 14:35 <wpwrak> it's a little weird. the description says "Write two dummy words to the device to flush the packet buffer.". this may explain the extra TCK cycles.
2012-09-26 14:37 <wpwrak> but they may be words "d" and "e"
2012-09-26 14:38 <wpwrak> step 5 is also confusing ... "Shift 32 bits out of the Status register", but only 15 cycles ?
2012-09-26 14:39 <wpwrak> seems that you'll have some experimenting to do :)
2012-09-26 14:40 <wpwrak> maybe urjtag sources can help, too
2012-09-26 14:40 <xiangfu> I already finish my code. and it's working.
2012-09-26 14:40 <xiangfu> 111 TCK, and 15 cycles when shift status register.
2012-09-26 14:41 <xiangfu> the status register is 16 bits. :)
2012-09-26 14:41 <wpwrak> kewl. then you know all the answers :)
2012-09-26 14:42 <wpwrak> maybe you should send xilinx a patch ;-)
2012-09-26 14:42 <xiangfu> (the purpose of the document is confuse you)
2012-09-26 14:42 <xiangfu> :-)
2012-09-26 14:43 <wpwrak> yeah, so it seems indeed ;-)
2012-09-26 14:47 <xiangfu> I will keep the code as it is. (111 TCK). if I meet some error I will try to add some 'dump words'.
2012-09-26 14:47 <xiangfu> ("Write two dummy words to the device to flush the packet buffer."). thanks. I ignore this line when read the document.
2012-09-26 14:48 <xiangfu> 159 - 111 = 48 that is 3 dump words.
2012-09-26 14:48 <xiangfu> maybe one at begin and two at the end.
2012-09-26 14:51 <xiangfu> the code is here : https://github.com/Wolfgang-Spraul/fpgatools/blob/master/mini-jtag/mini-jtag.c#L216
2012-09-26 14:51 <wpwrak> the 0x2000 already seems to be the dummy data. see also table 6-1 on page 111.
2012-09-26 14:51 <wpwrak> i guess page 116 is simply very wrong
