2014-10-14 02:21 <whitequark> it's ... misrepresented at best
2014-10-14 02:21 <whitequark> there is a reason tor browser bundle exists. if you send all your usual cookies through tor, you are immediately identifying yourself
2014-10-14 02:21 <whitequark> in a way, it makes things worse by giving you a false sense of security

2014-10-14 11:18 <SyntaxTerror> anyone around?
2014-10-14 11:18 <DocScrutinizer05> about my quick and dirty approach to talk to PPSU (/dev/ttyUSB0): it has a downside of creating "-rw-r--r-- 1 root root 5 Oct 14 13:12 /dev/ttyUSB0" when the PPSU is not properly enumerated ;-)
2014-10-14 11:21 <DocScrutinizer05> wondered why stuff suddenly fails, after I disconnected (and disassembled) the PPSU. Then I noticed this:
2014-10-14 11:21 <DocScrutinizer05> saturn:~ # ll /dev/ttyUSB*
2014-10-14 11:21 <DocScrutinizer05> -rw-r--r-- 1 root root         5 Oct 14 13:12 /dev/ttyUSB0
2014-10-14 11:21 <DocScrutinizer05> crw-rw---- 1 root dialout 188, 1 Oct 14 13:12 /dev/ttyUSB1
2014-10-14 11:24 <wpwrak> surprisingly, there doesn't even seem to be a redirect in bash that gives you write access without also implying O_CREAT. maybe i just didn't find it, or you have to use zsh or such ;-))
2014-10-14 11:36 SyntaxTerror has quit [Quit: My MacBook Pro has gone to sleep. ZZZzzz…]
2014-10-14 11:45 <DocScrutinizer05> wpwrak: might be related to permissions of parent dir. But maybe you can help me out how to check *programmaticaly* in shell script if a file is a character special device file?
2014-10-14 11:46 <wpwrak> you can use "test". (man test / help test)
2014-10-14 11:46 <DocScrutinizer05> ooh, and about create vs write: it's about >> and some parameter
2014-10-14 11:46 <DocScrutinizer05> aaah test, that's been it, thanks
2014-10-14 11:46 <wpwrak> but ... this still has a race condition: if the USB device disappears between test and >... access, you still get a new file
2014-10-14 11:47 <DocScrutinizer05> sure
2014-10-14 11:47 <wpwrak> and yes, you can prevent creation with permissions
2014-10-14 11:48 <wpwrak> a bit fragile, though. but as a just-for-joerg-at-home solution, why not.
2014-10-14 11:50 <DocScrutinizer05> parameter = noclobber
2014-10-14 11:52 <wpwrak> noclobber should still create it if it doesn't exist
2014-10-14 11:53 <DocScrutinizer05> err, I'm pretty sure it's meant to fail when file does exist, for >. and to fail when file does not exist, for >>
2014-10-14 11:53 <DocScrutinizer05> at least I'm sure I've read this somewhere
2014-10-14 11:54 <DocScrutinizer05> -C
2014-10-14 11:54 <DocScrutinizer05> If set, bash does not overwrite an existing file with the >, >&, and <> redirection operators. This may be overridden when creating output files by using the redirection operator >| instead of >.
2014-10-14 11:54 <DocScrutinizer05> isn't what I recal it been
2014-10-14 11:54 <DocScrutinizer05> it's missing the >> aspect
2014-10-14 11:57 <wpwrak> maybe write a C program that opens argv[1] without O_CREAT, then forks your shell script with the fd number as first arg ? then you can do your stuff in shell with a properly set up fd
2014-10-14 11:58 <wpwrak> well, or exec the shell. no fork needed if you want to optimize
2014-10-14 11:58 <wpwrak> (C) or any other real language. plenty of choices ;)
2014-10-14 12:01 <DocScrutinizer05> meh
2014-10-14 12:02 <DocScrutinizer05> I'm hardly motivated at all to check for type and existence of ttyUSB0

2014-10-14 12:23 <wpwrak> all you want is get rid of the O_CREAT. well, you could also write a wrapper library that removes O_CREAT from calls that open something in /dev. that way, you don't need to change your application

2014-10-14 12:34 SyntaxTerror has joined #qi-hardware
2014-10-14 12:35 <eintopf> wrapper library for systemcalls, I always search something like that to link other code to it
2014-10-14 12:36 <eintopf> for example, unstable closed source software and some watchdog which restarts the unstable software
2014-10-14 12:36 <wpwrak> LD_PRELOAD is your friend :)
2014-10-14 12:36 <eintopf> wpwrak: yea, I know this, but for systemcalls? I want the normal behaviour
2014-10-14 12:37 <eintopf> so only some call open_wrapper, afterwards then it should call open(2)
2014-10-14 12:37 <eintopf> from libc
2014-10-14 12:38 <eintopf> wpwrak: this should possible? It's like torsocks
2014-10-14 12:38 <eintopf> torsocks is wrapper for socket, send, recv etc...
2014-10-14 12:39 <eintopf> to make everything via tor, otherwise you need always applications with SOCKSv5 proxy support
2014-10-14 12:39 <wpwrak> sure. there ought to be some tutorials on the net. it used to be "deep wizardry", but now it's pretty well-established hackery
2014-10-14 12:39 <eintopf> and very important also wrapper for gethostbyname(2)
2014-10-14 12:39 <eintopf> mhh
2014-10-14 12:39 <eintopf> okay
2014-10-14 12:40 <eintopf> gethostbyname isn't a systemcall, yea
2014-10-14 12:40 <eintopf> that's something else, because readout also /etc/resolv.conf
2014-10-14 12:40 <eintopf> I think :/
2014-10-14 12:41 <eintopf> wpwrak: okay, maybe when I have time I will create a library where people could add easily code for that
2014-10-14 12:41 <eintopf> libhack
2014-10-14 12:41 <wpwrak> LD_PRELOAD is not limited to syscalls
2014-10-14 12:41 <eintopf> yep
2014-10-14 12:41 <eintopf> I know, at my university I compiled a second rootfs in $HOME/local
2014-10-14 12:42 <eintopf> because the pool environment is stupid
2014-10-14 12:42 <eintopf> they install libs and not dev debian packets
2014-10-14 12:42 <eintopf> and also, there was no autoconf and automake
2014-10-14 12:43 <eintopf> and then I make a:
2014-10-14 12:43 <eintopf> export LD_LIBRARY_PATH="$HOME/local/lib:$LD_LIBRARY_PATH"
2014-10-14 12:43 <eintopf> also for PKG_CONFIG_PATH
2014-10-14 12:44 <eintopf> and everything else
2014-10-14 12:44 <eintopf> my co-students want's always to know I can install new software on university pc's...
2014-10-14 12:44 <eintopf> but I told their "You don't wanna know that"
2014-10-14 12:44 <eintopf> because after system upgrade... I can recompile everything
2014-10-14 12:45 <eintopf> but I laugh always, because no autotools are installed
2014-10-14 12:45 <eintopf> I think the most people do java eclipse programming ;)
2014-10-14 12:46 <eintopf> so they don't need autotools (Oh yea I remember you name it autocrap)
2014-10-14 12:47 <eintopf> wpwrak: fvwm uses autocrap :P
2014-10-14 12:47 <eintopf> everything uses autocrap
2014-10-14 12:47 <eintopf> but the most weird buildsystem is the gcc buildsystem, never understand it
2014-10-14 12:47 <DocScrutinizer05> ((<wpwrak> all you want is get rid of the O_CREAT)) I hardly could care
2014-10-14 12:48 <DocScrutinizer05> I first check if ttyUSB is of right type, then I open it for *reading* which will fail if the file doesn't exist
2014-10-14 12:49 <DocScrutinizer05> ( cat /dev/ttyUSB& )
2014-10-14 12:58 <DocScrutinizer05> only then I'll open it for writing
2014-10-14 13:00 <DocScrutinizer05> what annoys me much more is root permissions needed
2014-10-14 13:01 <DocScrutinizer05> though prolly I should add user to dialout group
2014-10-14 13:01 arhuaco has quit [Remote host closed the connection]
2014-10-14 13:10 <DocScrutinizer05> actually I probably should do a find /sys -path '*cp210x*ttyUSB*'
2014-10-14 13:11 <DocScrutinizer05> the damn thing doesn't give away any hint that it's a PSU
2014-10-14 13:13 <DocScrutinizer05> they simply added the USB<->RS232 on a separate PCB. Standard, in no way customized. And powered by USB even when PSU is unpowered
2014-10-14 13:14 <DocScrutinizer05> that's why I never noticed before about the funny side effects of creating ttyUSB0 by my own script
2014-10-14 13:14 <DocScrutinizer05> the device file only vanishes when unplugging USB
2014-10-14 13:16 <DocScrutinizer05> http://privatepaste.com/462c28c138
2014-10-14 13:19 <DocScrutinizer05> you actually need to tell system: "I'm going to plug in a PPSU, please consider next cp210x showing up on USB as Voltcraft PPS-161005!"
2014-10-14 13:20 <DocScrutinizer05> s/161/16/
2014-10-14 13:20 <qi-bot> DocScrutinizer05 meant: "you actually need to tell system: "I'm going to plug in a PPSU, please consider next cp210x showing up on USB as Voltcraft PPS-16005!""
2014-10-14 13:22 <DocScrutinizer05> how would I rename a /dev/ttyUSB to some other more specific name?
2014-10-14 13:22 arhuaco has joined #qi-hardware
2014-10-14 13:23 <DocScrutinizer05> a symlink won't help since it doesn't notice when the ttyUSB vanishes
2014-10-14 13:23 <mth> udev rule?
2014-10-14 13:23 <DocScrutinizer05> prolly, yep. But I dunno how to rename in such rule
2014-10-14 13:24 <DocScrutinizer05> wait, udev creates the device, to start with, right?
2014-10-14 13:26 <mth> yes
2014-10-14 13:26 <DocScrutinizer05> also it's a tad nasty for a udev rule to go "interactive", i.e. wait answer (or check previously given command) of user, to declare next cp210x as PPSU
2014-10-14 13:26 <mth> udev does have a SYMLINK option, I presume it also cleans up the link at unplug then
2014-10-14 13:26 <DocScrutinizer05> ummm, makes sense

2014-10-14 17:29 <astr> SyntaxTerror, custom boards are easy with eoma-68, the the hard expencive bit the soc is taken care of so you can make a simple & cheep custom board with the lcd and touch driver and power supply on it that fits around the screen size you want and the eoma-68 card see rhombus-tech.net browse the sitemap and add your self to the mailing list and ask on there. while the website needs updating the project is moving forward
2014-10-14 17:30 <astr> and any money(orders) would help speed things up
