Oct 31 03:59:56 <veremitz> zmatt: how is that useful?
Oct 31 04:03:25 <zmatt> veremitz: uhh, the benefit of being able to update a shared data structure without a mutex seems obvious to me:  it especially avoids the pathological case of:  A takes lock, A gets preempted and kernel switches to B, B tries to take lock, and now the kernel has to get involved in dealing with the mutex and at least two more costly context-switches are needed
Oct 31 04:04:13 <zmatt> this is especially relevant if B is some high-priority real-time task
Oct 31 04:11:08 <zmatt> (I should actually be more specific: it's not just lock-free, it's wait-free)
Oct 31 04:12:08 <veremitz> hmm I Guess I've never got low-level enough to understand how to use that .. or how it might be better/worse than anything else :/

Oct 31 05:06:45 <veremitz> ah .. I have a weak grasp now .. thanks :D
Oct 31 05:12:01 <zmatt> ah, reading the comments in linux/rseq.h, it seems I need to set thread_rseq->ptr again if a restart happens...
Oct 31 05:12:34 <zmatt> hmm, and setting it to NULL afterwards isn't really needed
Oct 31 05:14:12 <zmatt> fixed

Oct 31 20:20:14 <tkwhite> first time here, anyone familiar with using a beaglebone blue with a 433Mhz radio?
Oct 31 20:44:17 <veremitz> tkwhite: what problems are you having? (not that I can answer your specific query, but i have experience of both aspects)
Oct 31 20:47:07 <tkwhite> ive got a project that requires 433Mhz comms, im making a shopping list right now, i was wondering i could use the beaglebone blue with a 433MHz telemetry radio kit
Oct 31 20:48:56 <tkwhite> i was trying to look for guides online, i imagine that i could connect the transmitter to my computer via USB and interface with SSH (Putty)
Oct 31 20:48:57 <tkwhite> t
Oct 31 20:49:25 <tkwhite> the receiver connected to the beaglebone blue, gnd, rx, tx, vcc
Oct 31 21:23:41 <veremitz> I'm using a Arduino with an AM 433 Tx
Oct 31 21:23:54 <veremitz> controls some mains power sockets :D
Nov 01 01:39:16 <set_> Hello!
Nov 01 01:39:56 <set_> Ghouls and Ghosts and BBB!
Nov 01 02:07:04 <set_> I got some ideas from W3 Schools online and changed some stuff. Here: https://github.com/silver2row/motocape/blob/master/templates/boboIV.html.
Nov 01 02:07:23 <set_> It makes a nice motor mover w/ funky text!
Nov 01 02:13:00 <set_> Bootstrap makes for nice additions (so far).
