2011-04-16 02:58 <rjeffries> I assume Tabula uses the time dimension to accomplish its magic?  https://www.technologyreview.com/computing/37406/
2011-04-16 03:06 <rjeffries> wpwrak speaking of SIMPLE networking protocols HsNeT is very simple and light http://www.hackeneering.com/Tiki/wiki/tiki-index.php?page=HsNet
2011-04-16 06:31 <wpwrak> rjeffries: (lighweight) oh sure, designing a non-standard protocol stack is always easy and fun. if it came to that, it wouldn't deny myself the pleasure of doing it entirely myself ;-)
2011-04-16 06:35 <wpwrak> rjeffries: (tabula) sounds as if they have a set of bits (8, apparently) for each config bit, plus a demux that picks one based on a central (?) clock. interesting approach.
2011-04-16 06:39 <wpwrak> rjeffries: such a thing may be able to increase the amount of available logic. won't help with the number of states, though.
2011-04-16 06:42 <wpwrak> rjeffries: you'd have to ask sebastien whether this is something that really helps. also, these are quite large chips, so they're targeting the very high end market.
2011-04-16 06:54 <wpwrak> ah, nice ... finally found a good formula for visualizing position-dependent BER. hmm, the day i document all this, it will be a tome of fearsome mathematics
2011-04-16 08:24 <wpwrak> hmm, and bit_error_probability*packets needs to be > 100 before this statistical test even begins to look useful. grr ;-(
2011-04-16 08:29 <wpwrak> i think i'll just hope atrf-path catches these as well :) (what i'm trying to detect is weak bypassing of RF power. if there's a problem with the capacitors, the signal strength will drop during a packet transmission. one way to find this is with fancy test equipment (e.g., an USRP). that measures the effect directly and is thus very accurate and fast. a less direct approach is to measure what this does on the probability of a bit goin
2011-04-16 08:29 <wpwrak> g bad. alas, this needs a lot of bad bits before any pattern emerges from the noise.)
2011-04-16 09:13 <whitequark> is happy
2011-04-16 09:13 <whitequark> bought a BIG 400ml can of FLUX-OFF
2011-04-16 10:56 <wpwrak> whitequark: very good. if you splatter any flux on yourself, you can now bathe it off ;-))
2011-04-16 10:57 <wpwrak> whitequark: now, what kind of flux is it for ? my guess would be RA/RMA resin.
2011-04-16 12:33 <whitequark> wpwrak: they assure that it could remove _all_ kinds of flux
2011-04-16 12:34 <whitequark> well, that does not correlate well with reality :/
2011-04-16 12:35 <whitequark> but the 35W ultrasonic bath I've also got is truly awesome
2011-04-16 12:35 <whitequark> it got rid of both RMA and that funky TT flux in just several minutes
2011-04-16 12:47 <Fusin> hi /me ;)
2011-04-16 13:01 <Fusin> How do I install Vista on nanonote? ;)
2011-04-16 13:04 <Fusin> more srious question: how to install an 8gb microSD card
2011-04-16 13:05 <Fusin> which device is the sd-slot? how to partition an how to format?
2011-04-16 13:06 <Fusin> is ext3fs good, or is another fs more accurate?
2011-04-16 13:07 <viric> /dev/mmc*, for the SD block devices
2011-04-16 13:08 <Fusin> thx for this information :)
2011-04-16 13:09 <viric> for fs, you will find many different preferences
2011-04-16 13:10 <Fusin> i want to use the 8gb m ostly for music, pictures and maybe video. mostly static (seldom rewrite)
2011-04-16 13:11 <viric> I don't think fs are going to make any difference about that
2011-04-16 13:12 <whitequark> wpwrak: I've finally did that. the seventh CP2102 finally works!! :)
2011-04-16 13:12 <whitequark> wpwrak: probably that NC pin was the caus
2011-04-16 13:12 <whitequark> *cause
2011-04-16 13:15 <whitequark> wpwrak: also, it still heats, too much for a simple usb-uart bridge, but much less than before
2011-04-16 14:05 <wpwrak> whitequark: (ultrasound) nice !
2011-04-16 14:05 <wpwrak> whitequark: (#7 lives) even better ! ;-)
2011-04-16 14:11 <Fusin> one step forward ;)
2011-04-16 14:18 <wpwrak> ultrasound sounds interesting. could be more efficient than all that scrubbing i do.
2011-04-16 14:26 <rozzin> Hm. Seems my openwrt build-environment is being contaminated by things on the host machine.
2011-04-16 14:29 <rozzin> Pygame finds an smpeg header, and wants to use it.
2011-04-16 14:29 <whitequark> wpwrak: ultrasound is ultra-awesome
2011-04-16 14:29 <whitequark> wpwrak: i can't ever say HOW it is freaking awesome
2011-04-16 14:30 <wpwrak> whitequark: ;-) did you get one with heating ?
2011-04-16 14:30 <whitequark> wpwrak: it is even more awesome when combined with flux-off. then all the dirt just goes away in beautiful stains
2011-04-16 14:30 <wpwrak> they're cheaper than i thought. low end starts < USD 100, even in argentina.
2011-04-16 14:31 <wpwrak> wow. strains. your boards must be really dirty ;-)
2011-04-16 14:32 <whitequark> wpwrak: yeah, my one is just a bit more expensive than $100, and it is really big, compared to some cheaper ones on the market
2011-04-16 14:32 <whitequark> wpwrak: (strains) the dictionary said 'stains'. well, there was a lot of RMA residues. you know, they're nonconductive, but ugly
2011-04-16 14:33 <whitequark> and that thing got all the board perfectly clean. no flux at all
2011-04-16 14:34 <whitequark> and, according to my feelings, no fat (from fingers) too, through that may be the combination of flux-off with water
2011-04-16 14:34 <wpwrak> (non-conductive) you may find that they aren't really ... i had circuits that didn't come out of reset because the flux conducted well enough to partially cancel the effect of a pull-up.
2011-04-16 14:34 <whitequark> huh, now I don't have to worry about that at all =)
2011-04-16 14:36 <rozzin> Oh, that might explain why dbus-x needed me to manually build libSM, too....
2011-04-16 14:38 <whitequark> wpwrak: so, my opinion is that the device (CT-405) is the awesome essence of awesomeness
2011-04-16 14:38 <wpwrak> interesting stuff indeed. i find the endless scrubbing quite inconvenient (and also a bit risky), so that may be something useful to try.
2011-04-16 14:40 <whitequark> wpwrak: absolutely.
2011-04-16 14:41 <whitequark> is very excited about it and ultrasound-washes everything he sees
2011-04-16 14:53 <rozzin> Hm. Nope--dbus-x needing libSM but not specifying that looks like a bug.
2011-04-16 14:55 <rozzin> Oh, nope--doesn't depend on libICE, either.
2011-04-16 14:58 <rozzin> removes libice-dev from his host system, does a `make clean' on libICE in openwrt, and watches dbus-x build successfully without libICE or libSM.
2011-04-16 15:03 <rozzin> I wonder how many packages this is happening for....
2011-04-16 15:03 <rozzin> starts rethinking autoconfiguration for his own packages....
2011-04-16 15:37 <whitequark> anyone knows how to etch brass?
2011-04-16 15:41 <C-Keen> whitequark: http://www.instructables.com/id/Etching-brass-plates/
2011-04-16 15:41 <C-Keen> whitequark: they require registration but bugmenot usually has an account that works
2011-04-16 15:45 <rozzin> I wonder if dbus really needs to be using AC_PATH_XTRA rather than AC_PATH_X....
2011-04-16 15:48 <whitequark> C-Keen: hm, looks like FeCl3 is fine for that
2011-04-16 15:53 <C-Keen> whitequark: I have to say that I have never tried this myself
2011-04-16 15:55 <whitequark> C-Keen: I'm trying that right now ;) so you'll soon have some real info about the process
2011-04-16 15:56 <whitequark> I want to etch the brass plates to make solder paste masks. manually applying the paste for ~8 board is boring enough
2011-04-16 15:56 <C-Keen> heh
2011-04-16 16:14 <Fusin> .
2011-04-16 16:38 <Fusin> what's wrong with ubuntu? doesn't know /dev/usb0 (I see only /dev/usbmonX'es)
2011-04-16 16:40 <Fusin> Laptop is an eeePC 1000 HG, internet connection is per GPRS (cellphone-chip)
2011-04-16 16:55 <whitequark> Fusin: that's a network interface, not a device file
2011-04-16 16:55 <whitequark> try "ip link"
2011-04-16 16:58 <Fusin> right, internet goes over ppp0, but for connecting the nanonote i need an usb0 (as in booklet and wiki), but i can't ifconfig usb0
2011-04-16 16:58 <Fusin> how do i setup that one?
2011-04-16 16:59 <whitequark> Fusin: well, if you load a corresponding module on nanonote and plug it into usb, the interface will appear automatically
2011-04-16 16:59 <whitequark> I don't have a NN, so you probably should ask someone else how to do that exactly on your distribution
2011-04-16 17:00 <Fusin> oh, i just bootet the nano, and voila: the usb0 is availlable in ubuntu :D
2011-04-16 17:00 <C-Keen> Fusin: the usb0 network device will only be available when the device is detected
2011-04-16 17:01 <C-Keen> Fusin: so only if you plug in your powered nanonote you will see it
2011-04-16 17:01 <Fusin> seems so
2011-04-16 17:01 <Fusin> lol
2011-04-16 17:01 <C-Keen> that's how it works
2011-04-16 17:02 <C-Keen> your kernel will see the even on usb, match the product / vendor id against a list and load up a network device driver that will act under the name of usb0
2011-04-16 17:02 <C-Keen> without the usb events happening there will be no device
2011-04-16 17:11 <Fusin> thx
2011-04-16 17:13 <wpwrak> whitequark: (clean everything) i hope you don't have pets ;-)
2011-04-16 19:04 <wpwrak> whitequark: interesting: http://www.circuitnet.com/articles/article_40106.shtml
2011-04-16 19:05 <wpwrak> whitequark: low power, high frequency, and if possible variable frequency
