#qi-hardware IRC log for Friday, 2013-11-15

wpwrakif you sign your binaries, people can verify that what they download comes from you. that's a good first line of defense.00:34
DocScrutinizer05wpwrak: worried?00:46
wpwrakby the time you have reason to worry, it's too late00:53
DocScrutinizer05hah00:55
DocScrutinizer05wpwrak: look at this for a nice example how to draw schematics that cause headache :-P  http://wstaw.org/m/2013/11/15/plasma-desktopwI3743.png05:55
DocScrutinizer05wpwrak: any idea why the placed MICP and MICN like *this*?05:56
DocScrutinizer05they*05:56
DocScrutinizer05also they use micamp2(TWO) for the first stage you see in that clip, and micamp1 (ONE!) for the second(!!) amplifier stage06:05
DocScrutinizer05micamp1 is the usual 0/+20dB06:05
viricwpwrak: yes, crucial information should never get into a computer, in any case. :)07:49
viricif you are targetted... I don't know if you can be careful enough against that, for a whole computer system07:51
wpwrakDocScrutinizer05: the usual explanation is "for historical reasons" :)09:07
wpwrakviric: yeah. viric vs. NSA doesn't sound too good. but then, you can at least make it a bit harder for them. every obstacle is an opportunity to trip09:09
viricyes09:14
pcercueiS2larsc: I didn't thank you for the beer :)16:24
larscno problem. you got back without problems?16:27
larscor are you still in paris?16:28
pcercueiS2I'm on the train16:33
pcercueiS2I left Paris 20min ago16:33
pcercueiS2it was scheduled for 8pm but I found one earlier16:33
viricwpwrak: in fact, I use rsa 2048 for certificates, and ECDHE (NIST) for the shared key. Not that insecure.17:54
whitequarkdevil lies at the endpoints18:03
viricyes18:12
kyakviric: sign the binary, sign the tarball as the best options. Or at least post a hash19:03
apeletemth larsc: g_ether gadget driver is loading by using the musb one -> http://paste.debian.net/66070/20:47
larscapelete: awesome :)20:48
apeletelarsc: don't know if it works, haven't tried to actually use it yet ;-)20:50
apeletetime to connect the nanonote to the computer via usb20:53
apeletelarsc: ok, let's say it's not quite ready for ethernet-over-usb yet -> http://paste.debian.net/66077/21:09
apeleteit seems like the kernel crashes as soon as the device is plugged into a host computer21:12
DocScrutinizer05:-/21:21
apeletethat might come from interrupt handling I guess21:27
apeleteirq and/or vbus hanlding in the glue layer; that's the parts I didn't put much thought into yet21:30
apeletelarsc mth: kernel seems to crash just by powering down the device -> http://paste.debian.net/66079/21:42
apeleteinteresting21:42
