2013-04-04 05:15 <wpwrak> grmbl. one of these oscilloscope-instead-of-printk moments again ...
2013-04-04 05:23 <wpwrak> first hint of trouble: zero activity on the I/O pins. yes, that would explain a thing or two ...
2013-04-04 05:24 <coyo> question for the channel: what is the scope of this community? would a do-it-yourself molten thorium floride fast breeder reactor fall under this community's scope?
2013-04-04 05:24 <coyo> in other words, would schematics and instructions be welcome here?
2013-04-04 05:26 <wpwrak> we're more into electronics than making friends with the nuclear power authorities. but i have to admit that the idea is intriguing ;-)
2013-04-04 05:26 <coyo> XD
2013-04-04 05:26 <wpwrak> i could imagine that the raw materials are a bit hard to find ?
2013-04-04 05:27 <coyo> well, there's nothing illegal about thorium. it may be theoretically possible to construct thermonuclear warheads with thorium by breeding it into uranium, but it's such a pain in the butt, and i have no need for those anyway
2013-04-04 05:27 <coyo> i just want power for my tesla coils :D
2013-04-04 05:27 <coyo> without the power company yelling at me about blacking out half the state
2013-04-04 05:29 <coyo> what you do is "invest" in thorium ore, and smelt and refine it yourself, then induce the initiating of reaction with a beta particle accelerator to provide the initial high energy neutrons without needing a crumb of uranium
2013-04-04 05:29 <coyo> let me doublecheck that really fast, hold on
2013-04-04 05:30 <wpwrak> oh, i think you can already have a lot of fun with a dirty bomb. that shouldn't be all that hard to make.
2013-04-04 05:30 <coyo> whoops
2013-04-04 05:30 <coyo> alpha particles
2013-04-04 05:30 <coyo> i meant alpha particles
2013-04-04 05:30 <wpwrak> of course, if you have a few uranium bricks at hand, that'll help
2013-04-04 05:32 <wpwrak> heh, someone's been busy: http://en.wikipedia.org/wiki/Liquid_fluoride_thorium_reactor#Disadvantages

2013-04-04 05:32 <coyo> hehe
2013-04-04 05:33 <wpwrak> seems that the best way to jump-start one of your reactors is if you have some decommissioned nuke to scavenge

2013-04-04 05:40 <coyo> :D
2013-04-04 05:41 <coyo> grabbing fissile material from a decommissioned nuke is a good way to get on every list out there
2013-04-04 05:41 <coyo> i'm sure there are other ways to do it successfully
2013-04-04 05:41 <coyo> without attracting undue attention
2013-04-04 05:42 <coyo> wpwrak: however, am i to take it that the schematics, how to videos, diagrams, and detailed instructions would not be unwelcome in this community?
2013-04-04 05:47 <coyo> i'm going to assume diy firearms are clearly unwelcome here. i cant find a tos on qi-hardware.com but it's pretty safe to assume.
2013-04-04 05:49 <coyo> :P
2013-04-04 06:34 <wpwrak> well, someone may find schematics entertaining :) but then, we're not really all that much into irradiating ourselves
2013-04-04 06:35 <wpwrak> maybe lekernel could steer you into a better direction once he's back. he's had some wacky talks at his conference in december
2013-04-04 06:38 <coyo> alright

2013-04-04 06:39 <coyo> according to this energy company saleswoman, they dont carry micro nuclear reactors, however, they do have large scale diesel generators with evaporative cooling systems that could provide enough sustained power for a city block or two
2013-04-04 06:39 <coyo> i may go that route
2013-04-04 06:39 <coyo> diy diesel generator, and diy syndiesel (aka biodiesel)

2013-04-04 07:26 <kyak> yeah, there is no good reason why the default partition layout is not upstream.. It's not like there are many modifications of Ben and the upstream holds the generic configuration..

2013-04-04 07:40 <kyak> wpwrak: out of your kernel tree, can i just extract drivers/net/ieee802154/atusb.c and compile it with 3.9 tree? Or did you do some other changes?
2013-04-04 07:42 <kyak> i see there are some changes to at86rf230.c.. So i'd need to recompile this module as well

2013-04-04 07:53 <wpwrak> oh, you don't need it for atusb
2013-04-04 07:54 <wpwrak> you need atusb.c, atusb.h, and at86rf230.h. that should be all.
2013-04-04 07:55 <wpwrak> btw, my kernel is 3.9.0-rc5+. so if your aim is 3.9, you may just use that one
2013-04-04 07:56 <wpwrak> https://github.com/wpwrak/ben-wpan-linux
2013-04-04 07:56 <wpwrak> (not the branch in qi-kernel. that one is obsolete.)
2013-04-04 08:01 <kyak> ok, i'll try with 3.8.5 which is my current kernel. If it doesn't work, i'll try with 3.9
2013-04-04 08:05 <viric> kyak: do you manage your workstation kernel manually?
2013-04-04 08:05 <kyak> viric: no, of course not.. It's arch linux who manages it for me
2013-04-04 08:06 <kyak> i have created the dkms-atusb package however
2013-04-04 08:06 <viric> ok
2013-04-04 08:06 <kyak> which is how i plan to work with atusb
2013-04-04 08:06 <viric> what is 'dkms'? :)
2013-04-04 08:07 <kyak> it's a special software that manages the list of external modules and recomiles it automatically on kernel version update
2013-04-04 08:07 <viric> wpwrak: do you make the atusb module build outside the kernel tree? or is it a patch to the kernel?
2013-04-04 08:07 <viric> kyak: ah ok
2013-04-04 08:07 <kyak> dynamic kernel management system, i guess
2013-04-04 08:08 <wpwrak> oh, i haven't even tried to build it as a module
2013-04-04 08:08 <kyak> wpwrak: ah! that's the key point :)
2013-04-04 08:08 <wpwrak> yeah, sorry. should have mentioned that :)
2013-04-04 08:08 <wpwrak> it wouldn't be surprised if it actually worked fine as a module. but then maybe it doesn't
2013-04-04 08:09 <viric> the linux trend is that things work as a module but not in-kernel :)
2013-04-04 08:10 <wpwrak> i try to stay ahead of the trend ;-)
2013-04-04 08:10 <wpwrak> besides, my test machine boots really fast
2013-04-04 08:11 <wpwrak> has a heavily gutted ubuntu that starts almost nothing
2013-04-04 08:11 <kyak> my laptop usually doesn't reboot, except for kernel updates and "reboot will fix it" issues
2013-04-04 08:11 <wpwrak> well, during krnel development, "reboot will fix it" happens rather often :)
2013-04-04 08:12 <wpwrak> at least to the point where the machine will talk to you again :)
2013-04-04 08:12 <kyak> sometimes my keyboard would just stop working. I then use mouse to reboot :)
2013-04-04 08:13 <viric> wpwrak: don't you develop on qemu or so?
2013-04-04 08:13 <kyak> this hasn't happened in a while though
2013-04-04 08:14 <kyak> guess qemu won't suffice for atusb.. Or maybe it will?

2013-04-04 14:18 <DocScrutinizer05> a question to the real sysop hackers: how would you manage to swap the /home HDD in a life system? As in: add a HDD, cp /home to new HDD, mount new HDD home on top of existing ext3 /home as unionfs, cp again...???
2013-04-04 14:18 <DocScrutinizer05> I gather there's NO way to accomplish that?
2013-04-04 14:21 security is now known as fire
2013-04-04 14:23 <DocScrutinizer05> another alternative approach: fuser -k SIGSTOP /home; dd /dev/sdb3 /dev/sdd3; <swap HDD sdb for HDD formerly known as sdd>; killall SIGCONT
2013-04-04 14:25 <hellekin> DocScrutinizer05: you could mount your new disk on /mnt, and rsync -a /home /mnt
2013-04-04 14:25 <DocScrutinizer05> :nod:
2013-04-04 14:26 <hellekin> of course, stopping processes using /home would help :)
2013-04-04 14:26 <DocScrutinizer05> but what do I do for the files that changed after rsync synced them?
2013-04-04 14:26 <DocScrutinizer05> yeah :-)
2013-04-04 14:26 <hellekin> login as root, fuser -k /home, rsync again :)

2013-04-04 14:28 <roh_> usually.. boot rescue system and do it from there
2013-04-04 14:28 <DocScrutinizer05> the whole point is I don't want to logout, since that would e.g. stop this irc client and make me basically lose my queries

2013-04-04 14:30 <DocScrutinizer05> I guess I will have to kill my uptime and do a reboot, accept some downtime for replacing this SATA HDD
2013-04-04 14:30 <DocScrutinizer05> roh: :nod:
2013-04-04 14:30 <roh> disks are .. well.. temporary storage. if you need more uptime. go raid
2013-04-04 14:31 <DocScrutinizer05> I guess my question is: how do I minimize that downtime, by doing backups in a proper way during regular use of PC
2013-04-04 14:32 <DocScrutinizer05> my idea been to get a new HDD, plug in, init s, dd, power down and swap HDD, boot
2013-04-04 14:33 <DocScrutinizer05> alas the shop requires me to bring in the defect HDD to give me a new one, which would mean several hours of PC being down since no proper /home existing
2013-04-04 14:35 <DocScrutinizer05> I might opt for buying a spare, do as sketched above, then bring in the defect HDD *after* PC already up and running on new one
2013-04-04 14:36 <DocScrutinizer05> will require two visits at shop, plus a couple of bucks for the new HDD spare
2013-04-04 14:37 <DocScrutinizer05> amazingly the "defect" HDD still kinda "works" - as in "no errors/problems during normal operation of PC, except for the onnoying TOCKTOCKTOCK it did during last few days every once in a while"

2013-04-04 14:43 <lindi-> DocScrutinizer05: but if you want to plan for this in the future then LVM with hot-pluggable disks should work
2013-04-04 14:43 <DocScrutinizer05> lindi-: my idea is not to hibernate but to suspend to disk, then dd-clone the whole friggin HDD, swap, resume
2013-04-04 14:44 <lindi-> DocScrutinizer05: I thought "hibernate" and "suspend to disk" meant the same thing
2013-04-04 14:44 <DocScrutinizer05> but I guess suspend to disk won't work, as usual
2013-04-04 14:44 <DocScrutinizer05> aaah

2013-04-04 14:45 <DocScrutinizer05> yeah, if it works once, it works every time (unless your swap already been used up so much that it can't take the RAM content anymore)

2013-04-04 14:56 <DocScrutinizer05> hellekin: so everything dry (again) at your site?

2013-04-04 14:59 <DocScrutinizer05> after swapping the first defect one for a replacement the both of them will form a nice raid
2013-04-04 15:01 <hellekin> wpwrak, DocScrutinizer05: all back to normal, less candles, one less PC :(
2013-04-04 15:01 xdpirate has quit [Ping timeout: 245 seconds]
2013-04-04 15:01 <hellekin> but the PC didn't die because of water: the dust was still intact.
2013-04-04 15:01 <hellekin> Instead it must have died of the recurring power outage
2013-04-04 15:01 <wpwrak> hellekin: losing a pc sucks :-(
2013-04-04 15:02 <wpwrak> hellekin: maybe it's just the power supply ?
2013-04-04 15:02 <hellekin> maybe
2013-04-04 15:02 <hellekin> not sure what part died, the motherboard lights up, but the CPU fan does not start
2013-04-04 15:03 <hellekin> if you have a spare power supply, might be useful to test
2013-04-04 15:05 <DocScrutinizer05> either cpu fan (they tend to not start again once worn out and stopped), or your 12V of PSU are dead
2013-04-04 15:05 <DocScrutinizer05> you tried helping fan to start up, manually pushing it a bit?
2013-04-04 15:06 <wpwrak> hmm, no new ones. but i think i have one that's been removed as preventive maintenance. may have small issues, though. that pc had been acting up on some occasions.
2013-04-04 15:06 <hellekin> DocScrutinizer05: nope, testing now
2013-04-04 15:06 <wpwrak> reminds me that i'm out of spare supplies. they've turned into consumables lately, much like disks :-(
2013-04-04 15:06 <hellekin> I don't have any electrical tools here, sso I cannot do any tests
2013-04-04 15:07 <hellekin> wpwrak: oh really? that sucks too

2013-04-04 15:09 <hellekin> nope, the fan plays dead

2013-04-04 15:34 <DocScrutinizer05> nah, HDD went TOCKTOCKTOCK for 15min
2013-04-04 15:35 <DocScrutinizer05> luckily it stopped a few minutes after I managed to send a ^C to ddrescue
2013-04-04 15:35 <DocScrutinizer05> already been afraid my complete dsktop would freeze
2013-04-04 15:35 <viric> are you recovering a hdD?
2013-04-04 15:35 <DocScrutinizer05> yep
2013-04-04 15:36 <DocScrutinizer05> of course it's BS to do a ddrescue from a mounted /home
2013-04-04 15:36 <DocScrutinizer05> but I thought it's probably better than nuttin

2013-04-04 16:07 <wpwrak> my system disk went early last month ...
2013-04-04 16:07 <wpwrak> still need to try to salvage some files that are in no backup.
2013-04-04 16:07 <viric> here one disk died, 1,5 months ago.
2013-04-04 16:07 <viric> (not the oldest in the system, by far)
2013-04-04 16:07 <wpwrak> i see a pattern :)
2013-04-04 16:08 <wpwrak> if you have an old maxtor, treat it well, it'll probably outlast you :)
2013-04-04 16:08 <viric> haha
2013-04-04 16:08 <viric> 3 months ago, another one died at the office
2013-04-04 16:09 <wpwrak> i wonder if it's time yet to move to SSD ...
2013-04-04 16:11 wolfspraul has quit [Ping timeout: 240 seconds]
2013-04-04 16:11 <wpwrak> oh, and i found out why my external WD USB disks didn't work: they have a little voltage regulator on the interface board that gets so hot that it no only burns the board but apparently also the disk's electronics underneath that board. at least, even after removing the disk, it wouldn't work in a pc.
2013-04-04 16:12 <viric> I recently found the idle3 timer thing
2013-04-04 16:12 <viric> on wd green
2013-04-04 16:12 <viric> (together with the start-stop count :)
2013-04-04 16:12 <wpwrak> do they have a start-stop limit ? like some ink printers ?
2013-04-04 16:13 <kristianpaul> wpwrak: mine was maxtor yeap
2013-04-04 16:13 <viric> here I bought a WD green, because seagate didn't work at all in my computer. it looked like a broken hard drive to the system
2013-04-04 16:13 <kristianpaul> wpwrak: i was thinking same about ssd as well
2013-04-04 16:13 <viric> wpwrak: no, wd green have a timer that stops spinning every 12,8 seconds of innactivity.
2013-04-04 16:13 <viric> wpwrak: very good for energy saving (in some usage patterns), but can be also very degrading for the disk life
2013-04-04 16:14 <kristianpaul> wpwrak: those external hardisk also have some sha or similar encryption on the fly i remenber..
2013-04-04 16:14 <viric> the 'respin' counter gets very high in those drives
2013-04-04 16:14 <viric> and idle3-tool is the tool to disable that 12,8s timer. :)
2013-04-04 16:16 <wpwrak> oh, an idle time beyond the regular mechanism. clever :)
2013-04-04 16:17 <wpwrak> kristianpaul: a dead maxtor ? nearly impossible. what did you do to it ?
2013-04-04 16:24 <kristianpaul> wpwrak: nothin
2013-04-04 16:24 <kristianpaul> but kernel was flooding me with ATA sync errors
2013-04-04 16:24 <kristianpaul> then i died on sunday

2013-04-04 16:52 <kyak> haven't tried communicating yet.. let me unpack atben :)
2013-04-04 16:52 <wpwrak> i tried unplugging it, which seems to be fine. still have to check whether i'm leaking memory, though. i don't trust those urb removal functions.

2013-04-04 16:59 <kyak> yeah, i was looking for something usb-related, but there was more like "tcp-write"
2013-04-04 16:59 <kyak> i shouldve' taken a picture
2013-04-04 17:00 <kyak> wpwrak: i'm looking at http://downloads.qi-hardware.com/people/werner/wpan/prod/setup.html#pcsw. Can you point me to specific instructions i can follow  to test communication?
2013-04-04 17:03 <wpwrak> oh, did you try iz assoc ? that would explain the oops
2013-04-04 17:03 <kyak> nope, didn't do that
2013-04-04 17:04 <kyak> i plugged out the atusb before doing rmmod
2013-04-04 17:04 <kyak> then i plugged it in.. After dozen of seconds it panicked
2013-04-04 17:04 <wpwrak> ah, interesting. need to try that then. just plug and unplug seems to work. but i didn't try modules.
2013-04-04 17:05 <wpwrak> here's the setup for a simple communication with izchat: http://pastebin.com/Ri9jm7zn
2013-04-04 17:05 <wpwrak> (required the latest user space tools on both ends, for the "iz set")
2013-04-04 17:05 <kyak> do i need to silence the mmc driver on ben?
2013-04-04 17:09 <wpwrak> yeah, remove everything else that touches mmc
2013-04-04 17:10 <wpwrak> on the ben, please use the owrt kernel. my kernel doesn't work yet there.
2013-04-04 17:13 <kyak> hm.. on ben, do i need a kernel module or something?

2013-04-04 17:35 <wpwrak> iz listphy
2013-04-04 17:35 <kyak> i think i need kmod-spi_atben
2013-04-04 17:35 <kyak> Could not get multicast group ID: No such file or directory
2013-04-04 17:36 <wpwrak> yes, spi_atben at86rf230 there's probably also a mac802154 maybe more *802154* modules
2013-04-04 17:37 <kyak> did you just install the packages on top of fresh reflash?
2013-04-04 17:37 <kyak> or they are built into the image?
2013-04-04 17:37 <kyak> i think i'm running my custom image, which lacks some (many) packages
2013-04-04 17:37 <wpwrak> i just installed owrt plus your updated tools package
2013-04-04 17:37 <kyak> ok, then i'll reflash_ben
2013-04-04 17:38 <wpwrak> if you have the stack in place, an "iz add" for a nonexisting device should yield: Receive failed: No such device
2013-04-04 17:38 <wpwrak> if you kernel has no idea about wpan, you get: Could not get multicast group ID: No such file or directory
2013-04-04 17:39 <kyak> what does lsmod show on your eben?
2013-04-04 17:39 <kyak> (good i didnt say iben)
2013-04-04 17:39 <wpwrak> my ben runs my monolithic kernel :)
2013-04-04 17:40 <wpwrak> but /lib/modules/3.3.8/ has these that look useful:
2013-04-04 17:40 <wpwrak> af_802154.ko spi_atben.ko at86rf230.ko ieee802154.ko  mac802154.ko
2013-04-04 17:41 <wpwrak> may you also need some of these: crc-itu-t.ko crc-ccitt.ko ipv6.ko
2013-04-04 17:41 <wpwrak> furthermore, for dirtpan, you'd need tun.ko
2013-04-04 17:41 <kyak> ok, i'll add all of those to my image later.. now reflashing the thing
2013-04-04 17:41 <wpwrak> the one you don't want is ks7010.ko :)
2013-04-04 17:42 <kyak> btw, ks7010 is the only module i currently have :)
2013-04-04 17:42 <wpwrak> so just modprobe --negate ;-)
2013-04-04 17:42 <kyak> i can't really install the modules via opkg, because the kernel package checksum is different from those kernel modules in the latest repo
2013-04-04 17:44 <kyak> this is something i didn't realize until now, because i sometimes used the opkg binary repo to install packages that were missing from my image
2013-04-04 17:44 <kyak> this works fine for regular packages, but not for kernel modules
2013-04-04 17:45 <kyak> Done:  78/635 //Damn the rootfs grown big
2013-04-04 17:46 <wpwrak> modprobe --force ?
2013-04-04 17:48 <kyak> it's on opkg level, before the modprobe :) i'm sure opkg has some force options, but i'm better of reflashing anyway
2013-04-04 17:48 <kyak> i'm not sure what else i changed, it's been a while
2013-04-04 17:50 <wpwrak> yeah, a clean owrt install, along with your updated package, should give you a working system
2013-04-04 17:50 <kyak> wpwrak: do you know how far is atusb backwards compatible?
2013-04-04 17:51 <kyak> i mean, what would be the lowest kernel version one should be able to run it with?
2013-04-04 17:52 <wpwrak> i don't really know. it may be able to go back a bit but i don't track those interfaces regularly.
2013-04-04 17:53 <wpwrak> but why linger in the past ? :)
2013-04-04 17:55 <kyak> that's true.. anyway, my router is currently at 3.8 kernel, and it will probably get 3.9 soon after it's out
2013-04-04 18:01 xdpirate_ is now known as xdpirate
2013-04-04 18:11 <kyak> wpwrak: ok, i had to insmod spi_atben manually
2013-04-04 18:11 <kyak> then i do iz add wpan-phy0 and get Receive failed: No such device

2013-04-04 18:36 <kyak> yep, it's reproducible
2013-04-04 18:36 <kyak> http://s017.radikal.ru/i443/1304/5b/a12344ee6ef2.jpg
2013-04-04 18:36 <kyak> atben->atusb seems to work
2013-04-04 18:36 <kyak> but not the other way
2013-04-04 18:37 <wpwrak> that's an odd one. lemme see ..
2013-04-04 18:38 <kyak> meanwhile, i'm enjoying sending nasty message from ben to my laptop...
2013-04-04 18:40 <kyak> i almost can't believe it's actually working when i unplug ben from usb
2013-04-04 18:40 <kyak> it's magic
2013-04-04 18:41 <kyak> most important thing - it's working from a bathroom
2013-04-04 18:42 <wpwrak> ;-))
2013-04-04 18:43 <wpwrak> seems that you have no dev->header_ops->create
2013-04-04 18:43 <wpwrak> now, why would that happen ...
2013-04-04 18:44 <wpwrak> actually .. no, that's being checked. hmm.
2013-04-04 18:46 <kyak> one thing that's bugging me.. the at86rf header is modified
2013-04-04 18:47 <kyak> however, all other modules, including atrf86 itself are built with unmodified header
2013-04-04 18:47 <kyak> could it be a problem?
2013-04-04 18:47 <kyak> i'm running all stock modules, except for atusb
2013-04-04 18:49 <wpwrak> maybe you need commit 0483546a3de329cad7705d42962edb09a28794c6
2013-04-04 18:50 <wpwrak> https://github.com/wpwrak/ben-wpan-linux/commit/0483546a3de329cad7705d42962edb09a28794c6
2013-04-04 18:51 <wpwrak> you mean "at86rf230.h" ? no, that's a copy. it doesn't exist in the original code. at some point in time i'll try to delete the original definitions
2013-04-04 18:51 <kyak> argh.. sounds like it's mac802154 recompilation...
2013-04-04 18:52 <wpwrak> i see a number of recent changes. you may want to try to just built the kernel from https://github.com/wpwrak/ben-wpan-linux
2013-04-04 18:53 <wpwrak> getting the .config right will be a bit of a pain, as usual, but i don't think it contains many cruel surprises
2013-04-04 18:53 <kyak> ok, i'll try just the kernel from your repo. I'm pretty sure it would work though
2013-04-04 18:53 <wpwrak> (recent changes) i mean to ieee 802.15.4
2013-04-04 18:55 <kyak> if all these change make it to 3.9, my evil plan would work
2013-04-04 18:55 <kyak> wpwrak: ok, thank you very much! it was fun!
2013-04-04 18:56 <kyak> time to go now
2013-04-04 18:58 <wpwrak> the drivers may not make it this time but i hope some bug fixes and such do

2013-04-04 22:23 <wpwrak> ah, someone asked about qemu. dunno how good it is with usb. a prefer to run things on the bare metal :) have to admit that some oopses can be a bit annoying, when things scroll off the console. but then, it's easy enough to add a loop that stops the system after the interesting part of its complaints.
2013-04-04 22:28 <viric> no kgdb?
2013-04-04 22:28 <wpwrak> kyak: we do indeed not need the full MAC address
2013-04-04 22:28 <wpwrak> viric: i developed my workflow when kgdk and such were still banned :)
2013-04-04 22:29 <wpwrak> i sometimes use gdb on the live kernel, though (with /proc/kcore)
2013-04-04 22:30 <wpwrak> most of the time, i find that debuggers don
2013-04-04 22:32 <wpwrak> a few printks/printf often give you that information more rapidly. of course, then retrieving details costs more time
2013-04-04 22:32 <wpwrak> 't really make finding the bug faster. they give you a lot of control, but at the same time you have to spend time on a lot more details
