Nov 14 16:00:21 <DocScrutinizer05> ((<fling> So I'm about to buy but I want to be sure the battery will not die in 30 minutes of running terminal + mosh + gprs)) *mosh* most likely will drain the battery in less than 4h on UMTS data
Nov 14 16:00:46 <fling> hmm hmmm
Nov 14 16:00:48 <DocScrutinizer05> even on N900
Nov 14 16:00:58 <fling> DocScrutinizer05: because of high cpu usage of mosh-client?
Nov 14 16:01:30 <DocScrutinizer05> since mosh is doing permanent keep-alive packet sending, which keeps UMTS transmitter active at maybe 0.5W all the time
Nov 14 16:01:54 <DocScrutinizer05> mosh is insane design
Nov 14 16:02:19 <DocScrutinizer05> completely broken design for *mobile*
Nov 14 16:03:46 <DocScrutinizer05> I'm running xchat on my N900 24/7 and when I am out with my N900 it stays online with one battery for maybe 15..20h
Nov 14 16:03:48 <fling> What is wrong with this packet? Will it drain additional power while I'm chatting? :>
Nov 14 16:04:05 <DocScrutinizer05> which packet?
Nov 14 16:04:16 <fling> >> permanent keep-alive packet sending
Nov 14 16:04:22 <DocScrutinizer05> keep-alive packets?
Nov 14 16:04:26 <fling> yes
Nov 14 16:04:36 <DocScrutinizer05> well, it's data to get transmitted over the air
Nov 14 16:04:51 <DocScrutinizer05> so it's similar to you constantly typing
Nov 14 16:04:58 <DocScrutinizer05> all the time
Nov 14 16:05:15 <fling> more data = more battery, right?
Nov 14 16:05:24 <DocScrutinizer05> and data transfer over-the-air costs lots of energy
Nov 14 16:05:36 <fling> ok I did not know that
Nov 14 16:05:54 <DocScrutinizer05> basically no, since mosh is sending so frequently that the transmitter never stops sending, on UMTS
Nov 14 16:06:41 <fling> Ok, looks like I need another one patch for it, thanks for the info
Nov 14 16:06:44 <DocScrutinizer05> so even when you do "additional2 typing, the energy consumed will not change significantly. It's always at maximum, with mosh
Nov 14 16:07:39 <fling> what about 30s timeout between packets?
Nov 14 16:08:00 <fling> is it better but still bad?
Nov 14 16:08:10 <DocScrutinizer05> UMTS TX stays on for iirc 15s after last byte sent
Nov 14 16:09:10 <DocScrutinizer05> for 30s you need ~50% of energy you'd need for <=15s between bytes to send
Nov 14 16:09:30 <fling> right
Nov 14 16:10:15 <DocScrutinizer05> for 500kB/s you need basically same energy as for one ping per 15s
Nov 14 16:10:20 <DocScrutinizer05> == maximum
Nov 14 16:11:00 <DocScrutinizer05> forget mosh, it's braindead design
Nov 14 16:11:19 <fling> But I like it's local echo
Nov 14 16:11:24 <DocScrutinizer05> tzz
Nov 14 16:11:50 <fling> This is the only feature I need from mosh :>
Nov 14 16:11:55 <DocScrutinizer05> I guess you can set local echo on ~17 different ways on any tty
Nov 14 16:12:10 <fling> btw mosh-server eats 100% cpu on old celeron even without hardening
Nov 14 16:12:28 <DocScrutinizer05> great! ;-P
Nov 14 16:12:30 <fling> >> ~17 different ways
Nov 14 16:12:33 <fling> tell me more :>
Nov 14 16:12:41 <DocScrutinizer05> man stty
Nov 14 16:12:50 <fling> when typing ^
Nov 14 16:13:28 <DocScrutinizer05> dunno, probably even bash has a setting to make it do local echo
Nov 14 16:13:45 <DocScrutinizer05> most likely xterm has
Nov 14 16:13:53 <DocScrutinizer05> for sure tty device has
Nov 14 16:14:13 <DocScrutinizer05> there should be another option to set it on line discipline
Nov 14 16:14:15 <fling> DocScrutinizer05: so it will depend on terminal I will use on neo900
Nov 14 16:14:44 <DocScrutinizer05> sorry, have to run
Nov 14 16:14:49 <fling> cya
Nov 14 16:14:54 <DocScrutinizer05> I guess somebody else here can help you out
Nov 14 16:17:09 <fling> Which modem and wifi will be used in neo900?
Nov 14 21:43:50 <Artox> \o everyone
Nov 14 21:44:12 <Artox> I finally got my gps "mouse" working
Nov 14 21:45:29 <Artox> Here is teh script I made to start/stop teh service: http://pastebin.com/uw8dTjQ0
Nov 14 22:08:59 <Artox> but I fail to run it at boot :|
Nov 14 22:09:12 <Artox> I guess I have to make a systemd service
Nov 14 22:20:35 <Artox> and my systemd service works :)
Nov 14 22:20:39 <Artox> Have a good night everyone
