<rjeffries> I assume Tabula uses the time dimension to accomplish its magic?  https://www.technologyreview.com/computing/37406/
<rjeffries> wpwrak speaking of SIMPLE networking protocols HsNeT is very simple and light http://www.hackeneering.com/Tiki/wiki/tiki-index.php?page=HsNet
<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 ;-)
<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.
<wpwrak> rjeffries: such a thing may be able to increase the amount of available logic. won't help with the number of states, though.
<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.
<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
<wpwrak> hmm, and bit_error_probability*packets needs to be > 100 before this statistical test even begins to look useful. grr ;-(
<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
<wpwrak> g bad. alas, this needs a lot of bad bits before any pattern emerges from the noise.)
<whitequark> is happy
<whitequark> bought a BIG 400ml can of FLUX-OFF
<wpwrak> whitequark: very good. if you splatter any flux on yourself, you can now bathe it off ;-))
<wpwrak> whitequark: now, what kind of flux is it for ? my guess would be RA/RMA resin.
<whitequark> wpwrak: they assure that it could remove _all_ kinds of flux
<whitequark> well, that does not correlate well with reality :/
<whitequark> but the 35W ultrasonic bath I've also got is truly awesome
<whitequark> it got rid of both RMA and that funky TT flux in just several minutes
<Fusin> hi /me ;)
<Fusin> How do I install Vista on nanonote? ;)
<Fusin> more srious question: how to install an 8gb microSD card
<Fusin> which device is the sd-slot? how to partition an how to format?
<Fusin> is ext3fs good, or is another fs more accurate?
<viric> /dev/mmc*, for the SD block devices
<Fusin> thx for this information :)
<viric> for fs, you will find many different preferences
<Fusin> i want to use the 8gb m ostly for music, pictures and maybe video. mostly static (seldom rewrite)
<viric> I don't think fs are going to make any difference about that
<whitequark> wpwrak: I've finally did that. the seventh CP2102 finally works!! :)
<whitequark> wpwrak: probably that NC pin was the caus
<whitequark> *cause
<whitequark> wpwrak: also, it still heats, too much for a simple usb-uart bridge, but much less than before
<wpwrak> whitequark: (ultrasound) nice !
<wpwrak> whitequark: (#7 lives) even better ! ;-)
<Fusin> one step forward ;)
<wpwrak> ultrasound sounds interesting. could be more efficient than all that scrubbing i do.
<rozzin> Hm. Seems my openwrt build-environment is being contaminated by things on the host machine.
<rozzin> Pygame finds an smpeg header, and wants to use it.
<whitequark> wpwrak: ultrasound is ultra-awesome
<whitequark> wpwrak: i can't ever say HOW it is freaking awesome
<wpwrak> whitequark: ;-) did you get one with heating ?
<whitequark> wpwrak: it is even more awesome when combined with flux-off. then all the dirt just goes away in beautiful stains
<wpwrak> they're cheaper than i thought. low end starts < USD 100, even in argentina.
<wpwrak> wow. strains. your boards must be really dirty ;-)
<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
<whitequark> wpwrak: (strains) the dictionary said 'stains'. well, there was a lot of RMA residues. you know, they're nonconductive, but ugly
<whitequark> and that thing got all the board perfectly clean. no flux at all
<whitequark> and, according to my feelings, no fat (from fingers) too, through that may be the combination of flux-off with water
<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.
<whitequark> huh, now I don't have to worry about that at all =)
<rozzin> Oh, that might explain why dbus-x needed me to manually build libSM, too....
<whitequark> wpwrak: so, my opinion is that the device (CT-405) is the awesome essence of awesomeness
<wpwrak> interesting stuff indeed. i find the endless scrubbing quite inconvenient (and also a bit risky), so that may be something useful to try.
<whitequark> wpwrak: absolutely.
<whitequark> is very excited about it and ultrasound-washes everything he sees
<rozzin> Hm. Nope--dbus-x needing libSM but not specifying that looks like a bug.
<rozzin> Oh, nope--doesn't depend on libICE, either.
<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.
<rozzin> I wonder how many packages this is happening for....
<rozzin> starts rethinking autoconfiguration for his own packages....
<whitequark> anyone knows how to etch brass?
<C-Keen> whitequark: they require registration but bugmenot usually has an account that works
<rozzin> I wonder if dbus really needs to be using AC_PATH_XTRA rather than AC_PATH_X....
<whitequark> C-Keen: hm, looks like FeCl3 is fine for that
<C-Keen> whitequark: I have to say that I have never tried this myself
<whitequark> C-Keen: I'm trying that right now ;) so you'll soon have some real info about the process
<whitequark> I want to etch the brass plates to make solder paste masks. manually applying the paste for ~8 board is boring enough
<C-Keen> heh
<Fusin> .
<Fusin> what's wrong with ubuntu? doesn't know /dev/usb0 (I see only /dev/usbmonX'es)
<Fusin> Laptop is an eeePC 1000 HG, internet connection is per GPRS (cellphone-chip)
<whitequark> Fusin: that's a network interface, not a device file
<whitequark> try "ip link"
<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
<Fusin> how do i setup that one?
<whitequark> Fusin: well, if you load a corresponding module on nanonote and plug it into usb, the interface will appear automatically
<whitequark> I don't have a NN, so you probably should ask someone else how to do that exactly on your distribution
<Fusin> oh, i just bootet the nano, and voila: the usb0 is availlable in ubuntu :D
<C-Keen> Fusin: the usb0 network device will only be available when the device is detected
<C-Keen> Fusin: so only if you plug in your powered nanonote you will see it
<Fusin> seems so
<Fusin> lol
<C-Keen> that's how it works
<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
<C-Keen> without the usb events happening there will be no device
<Fusin> thx
<wpwrak> whitequark: (clean everything) i hope you don't have pets ;-)
<wpwrak> whitequark: low power, high frequency, and if possible variable frequency
