2011-10-11 00:25 <zrafa> kristianpaul: wpwrak : I will not show our cool scope and you will envy our tools because you will have the doub haha
2011-10-11 01:35 <wpwrak> zrafa: ;-)
2011-10-11 02:06 <DocScrutinizer> wpwrak: hey, every now and then I run again into "originally written by Werner Almesberger" when it comes to cmdline tools
2011-10-11 02:07 <DocScrutinizer> I wonder if that means anything that it's usually in manpages that I rarely ever need - probably because the tool is so pretty intuitive to use :-)
2011-10-11 02:09 <wpwrak> killall ? ;-)
2011-10-11 02:11 <wpwrak> i can't quite claim the credit for the ease of use of the tools in psmisc - they all were inspired by SGI's IRIX
2011-10-11 02:12 <wpwrak> there are some more in common use, but they're less intuitive and tend to be used somewhere in the bowels of the system. things like pivot_root.
2011-10-11 02:34 <DocScrutinizer> OMG pivot_root :-D
2011-10-11 02:34 <wpwrak> (-:C
2011-10-11 02:35 <DocScrutinizer> >>Some of the more obscure uses of pivot_root() may quickly lead to insanity.<<
2011-10-11 02:39 <DocScrutinizer> funny enugh I've read pivot_root manpage just yesterday
2011-10-11 02:40 <wpwrak> hmm, i wonder if a had a hand in writing this man page ... don't quite remember :)
2011-10-11 02:41 <wpwrak> well, not in the man page itself. i'm pretty sure about that. but the README things were copied from.
2011-10-11 02:41 <DocScrutinizer> well, no Almesberger mentioned in pivot_root manpage, it's actually been killall that I referred to above
2011-10-11 02:42 <wpwrak> heh, a popular choice :)
2011-10-11 04:58 <qwebirc26856> Just got the nanonote today.  I booted it up, then reflashed, but now it will only turn on when plugged into the usb.  
2011-10-11 04:59 <qwebirc26856> Is there something I am not aware of?  
2011-10-11 05:00 <wpwrak> qwebirc26856: welcome to the club ! :) sounds like an empty or not properly connected battery
2011-10-11 05:01 <wpwrak> maybe try removing USB and battery, wait ~20 seconds, then insert the battery again, then press the power button for a few seconds. that should do the trick.
2011-10-11 05:01 <qwebirc26856> Each time I plug the usb cable in the light flashes red then turns off.
2011-10-11 05:01 <wpwrak> that is, unless the battery is empty
2011-10-11 05:05 <qwebirc26856> When I charged the battery earlier today the red light stayed on.  It turns off now so I think the battery is good.  No luck with waiting 20 seconds with all power unplugged.
2011-10-11 05:06 <wpwrak> hmm, strange then. when you bring it up with USB, everything looks healthy ?
2011-10-11 05:07 <qwebirc26856> wpwrak:  Yep.  New os and all.
2011-10-11 05:07 <wpwrak> what exactly did you install ?
2011-10-11 05:09 <qwebirc26856> The latest openWrt image
2011-10-11 05:11 <wpwrak> hmm, haven't heard of any such issues with it. i didn't update things in my bens for a while.
2011-10-11 05:11 <wpwrak> maybe someone else knows ?
2011-10-11 05:13 <qwebirc26856> I will do another reflash, see what happens.  Thanks
2011-10-11 06:51 <qwebirc26856> wpwrak:  one of the spring wires connecting the battery was pushed back.  
2011-10-11 06:51 <qwebirc26856> I brought it out and now the battery is charging.
2011-10-11 06:51 <qwebirc26856> Thanks for the suggestions.
2011-10-11 08:10 <rejon_> heya, does nanonote support this project http://taskwarrior.org
2011-10-11 08:10 <rejon_> hahaha
2011-10-11 08:10 <rejon_> just had another thought about the nanonote and html5 apps
2011-10-11 08:10 <rejon_> i only want to use the nanonote as an offline device
2011-10-11 08:10 <rejon_> only CLI
2011-10-11 08:10 <rejon_> those are the basics for a whole company
2011-10-11 08:11 <rejon_> just implement a web service on top of all the commandline apps
2011-10-11 08:11 <rejon_> from top to bottom
2011-10-11 08:11 <rejon_> with the synchronization layer as the for pay service
2011-10-11 08:11 <rejon_> nanonote is the embodiment of the strength of the service
2011-10-11 09:29 <viric> kyak: I think your use of 'rss' is similar to my use of 'email' (regarding mailing lists) :)
2011-10-11 11:24 <kristianpaul> rejon_: i do use my nanonote to browse static html pages elinks worsks decently
2011-10-11 11:25 <kristianpaul> and veyr handy, you can have lots of manuals, and guides in less of 512Mb :-)
2011-10-11 11:44 <rejon_> kristianpaul, great

2011-10-11 16:52 <wpwrak> zrafa: now, tell us about the dinosaur rodolfo dug out for you :)
2011-10-11 17:00 <kristianpaul> I was thinking the time, we have lots of already command line apps ported to nanonote
2011-10-11 17:01 <kristianpaul> but all still command, and seems SDL programing is hard to implement?
2011-10-11 17:01 <kristianpaul> So what alternative we have for example to make this things esier
2011-10-11 17:01 <kristianpaul> an example,sox
2011-10-11 17:02 <wpwrak> a good start may be to use X ;-)
2011-10-11 17:02 <kristianpaul> ahh !!
2011-10-11 17:02 <kristianpaul> i was about to ask about sdl python bidings? or may be curses?
2011-10-11 17:02 <wpwrak> SDL has quite some stuff, too. but it's a lot more obscure than the usual suspects for X.
2011-10-11 17:02 <wpwrak> (obscure) in the sense of "unknown". not necessarily hard to understand
2011-10-11 17:02 <kristianpaul> i mean not the BLUE curses, but something purple, green yellow may look at least different
2011-10-11 17:03 <kristianpaul> but you dont need soem very very elaborate
2011-10-11 17:03 <kristianpaul> for example sox, and script that generate two 3 buttons, record play stop
2011-10-11 17:03 <kristianpaul> may be reverse/forward too
2011-10-11 17:03 <kristianpaul> written in what? perl? python? with SDL.ncurses?
2011-10-11 17:04 <wpwrak> i think SDL has some widget set
2011-10-11 17:04 <wpwrak> http://members.chello.nl/w.boeke/SDL-widgets/index.html
2011-10-11 17:05 <wpwrak> fancy enough ? :)
2011-10-11 17:05 <kristianpaul> for jlime zrafa did a nice fronted for sox,in seconds !!
2011-10-11 17:05 <kristianpaul> but of course was all X and gtk? (in dont rember well)
2011-10-11 17:05 <wpwrak> he may have used SDL. he did quite a few things with it.
2011-10-11 17:06 <kristianpaul> yeah, looks nice
2011-10-11 17:20 <viric> wpwrak: wow, nice widgets. That's SDL? great
2011-10-11 17:21 <viric> do you run linux 3 in the nanonote?
2011-10-11 17:21 <kristianpaul> soon !
2011-10-11 17:21 <viric> ah :)
2011-10-11 17:23 <kristianpaul> wpwrak: too fancy actually, i was thinking something more simmple
2011-10-11 17:24 <kristianpaul> some buttons and text boxes
2011-10-11 17:24 <kristianpaul> there is not much space in screen i think..
2011-10-11 17:26 <Ayla> try EFL
2011-10-11 17:26 <kristianpaul> ay,yes B_Lizzard mentioned that too i remnber. right?
2011-10-11 17:26 <kristianpaul> say/ah
2011-10-11 17:27 <B_Lizzard> What
2011-10-11 17:27 <kristianpaul> You think EFL rules for embeded?
2011-10-11 17:28 <B_Lizzard> Not yet, there's little keyboard accessibility thingie going on
2011-10-11 17:28 <B_Lizzard> Otherwise, I guess it is.
2011-10-11 17:28 <B_Lizzard> The grey stuff is GTK 1.2
2011-10-11 17:29 <B_Lizzard> Last release: 2001
2011-10-11 17:29 <B_Lizzard> AW YEAH
2011-10-11 17:30 <kristianpaul> hum,may be gtk will not be so slow for simple menus
2011-10-11 17:31 <kristianpaul> or agree with wpwrak and switch to X, (wich looks kinda mad to the date)
2011-10-11 17:31 <B_Lizzard> Muffinman uses X
2011-10-11 17:32 <kristianpaul> you have to remenber us that all time !!? ;)
2011-10-11 17:33 <B_Lizzard> MUFFINMAN IS BETTER
2011-10-11 17:33 <B_Lizzard> I AM RULE
2011-10-11 17:33 <wpwrak> all your base belong to us ?
2011-10-11 17:34 <Ayla> are belong*

2011-10-11 17:46 <kristianpaul> did gtkperfm ran slow at old days?
2011-10-11 18:01 <zrafa> kristianpaul: when you talk about gtk you need to specify exactly which versoin of gtk
2011-10-11 18:04 <kristianpaul> yes sorry
2011-10-11 18:04 <kristianpaul> but i dont know
2011-10-11 18:05 <viric> have you seen the film Moebius? Does the Buenos Aires metro inspire all that as in the film? :)
2011-10-11 18:07 <wpwrak> maybe in a few centuries. they're extending the network very very slowly.
2011-10-11 18:08 <viric> :) ok
2011-10-11 18:11 <zrafa> kristianpaul: gtk1.. which blizzard talks is from 2001 last release
2011-10-11 18:12 <zrafa> kristianpaul: and it is really fast for embedded
2011-10-11 18:12 <zrafa> kristianpaul: but no gtk2.. IIRC gtk2 uses a lot float p calculations
2011-10-11 18:12 <zrafa> kristianpaul: and if you use it for our tiny embedded world you will kill yourself :)
2011-10-11 18:13 <zrafa> wpwrak: you there¡?
2011-10-11 18:13 <zrafa> wpwrak: I have news.. you would llike to read :)
2011-10-11 18:14 <wpwrak> tell me ! :)
2011-10-11 18:15 <zrafa> wpwrak: scope: noising model  n-220 oscilloscope
2011-10-11 18:16 <wpwrak> what does "noising model" mean ?
2011-10-11 18:17 <zrafa> Noising is the machine. 
2011-10-11 18:17 <zrafa> is the name
2011-10-11 18:17 <zrafa> or mark
2011-10-11 18:17 <wpwrak> oh, i see
2011-10-11 18:18 <wpwrak> insteresting choice of name :)
2011-10-11 18:19 <wpwrak> seema that all google hits are about de-noising ...
2011-10-11 18:20 <wpwrak> is it really exactly "noising" ?
2011-10-11 18:20 <zrafa> wpwrak: yes :) .. and I can not find a picture using google images :P
2011-10-11 18:20 <zrafa> it is Noising model n-220 oscilloscope
2011-10-11 18:20 <zrafa> made in korea
2011-10-11 18:21 <wpwrak> can you take a picture ?
2011-10-11 18:21 <zrafa> yes, at home. Rodolfo lend me it so I will bring to home
2011-10-11 18:21 <steve|m> a scope which has "Noise" in its name.. nice ;)
2011-10-11 18:21 <kristianpaul> how many channels it have?
2011-10-11 18:21 <kristianpaul> he bring the probes as well?
2011-10-11 18:21 <kristianpaul> steve|m: ;)
2011-10-11 18:22 <zrafa> kristianpaul: I see ch A and ch B
2011-10-11 18:22 <kristianpaul> good
2011-10-11 18:23 <kristianpaul> do you recognice any computer-like port on it?
2011-10-11 18:25 <wpwrak> does it say something about the analog bandwidth somewhere ?
2011-10-11 18:25 <wpwrak> also, does it have a screen ? if yes, LCD or CRT ?
2011-10-11 18:26 <kristianpaul> does it turn on?
2011-10-11 18:26 <zrafa> wpwrak: I would say CRT
2011-10-11 18:26 <wpwrak> does it even work with electricity ? ;-)
2011-10-11 18:26 <zrafa> kristianpaul: yes
2011-10-11 18:26 <kristianpaul> noce
2011-10-11 18:26 <wpwrak> (crt) uh uh ... that's not very promising
2011-10-11 18:27 <kristianpaul> s/noce/nice
2011-10-11 18:27 <zrafa> you all envy me
2011-10-11 18:27 <zrafa> haha
2011-10-11 18:28 <wpwrak> 220 may mean 2 channels, 20 MHz. these are quite common characteristics for analog scopes.
2011-10-11 18:30 <wpwrak> well, it'll let you see simple signal shapes. it won't help much with analyzing complex digital communications, though.
2011-10-11 18:37 <kristianpaul> zrafa: actually sebastien have an analog one too i had read
2011-10-11 18:39 <zrafa> wpwrak: I am not sure that I will understand complex digital communications
2011-10-11 18:39 <zrafa> wpwrak: so anyway, with a good scope or not I will need a real hand from hw people
2011-10-11 18:40 <zrafa> wpwrak: I meant "I am sure that I will not understand ... " :)
2011-10-11 18:45 <wpwrak> oh, you'll learn. usb is a very good topic for learning quite a lot :)
2011-10-11 19:27 <zrafa> wpwrak: we just test a simple version of blinkenlights turning on/off the pin 9 of PDDAT (CMD on ubb), with 50000 microseconds between setting/clearing and I saw the signal on scope :)
2011-10-11 19:29 <wpwrak> hehe :)
2011-10-11 19:30 <wpwrak> congratulations on your first real scope experience ! ;-)
2011-10-11 19:44 <zrafa> wpwrak: thanks, but all is from your work . I modified blinkenlights :)
2011-10-11 19:44 <zrafa> and rodolfo did the scope part haha
2011-10-11 19:44 <DocScrutinizer> classical scopes are useful for analog only
2011-10-11 19:46 <DocScrutinizer> where analog includes proper analog signal levels (and shapes, sometimes) on digital lnes
2011-10-11 19:46 <DocScrutinizer> lines
2011-10-11 19:47 <wpwrak> DocScrutinizer: yeah, you need a dark room and quick eyes to do much with them for non-repetitive signals
2011-10-11 19:47 <wpwrak> zrafa: (reused blinkenlights) so you put it to good use. very nice ! :)
2011-10-11 19:47 <DocScrutinizer> on a second thought, levels includes the aspects of shapes that can usefully get examined with a scope
2011-10-11 19:49 <DocScrutinizer> though -> wiki eyepattern
2011-10-11 19:49 <wpwrak> heh, don't get me started :)
2011-10-11 19:51 <wpwrak> still need a to see a scope that can do this without costing as much as a decent car: http://people.openmoko.org/werner/rigol/eye-out-better.png
2011-10-11 19:53 <wpwrak> (that was generated by scripts operating on a long recording of my DSO)
2011-10-11 20:07 <DocScrutinizer> wpwrak: isn't averaging over 106 samples somewhat defeating the purpose of an eye pattern?
2011-10-11 20:08 <wpwrak> it's not averaging. it's overlaying.
2011-10-11 20:08 <DocScrutinizer> oooh
2011-10-11 20:08 <viric> why is that called eye pattern?
2011-10-11 20:08 <DocScrutinizer> see wiki
2011-10-11 20:08 <DocScrutinizer> it "looks like two eyes"
2011-10-11 20:09 <viric> There were no results matching the query.
2011-10-11 20:09 <DocScrutinizer> esp with sine waves ;-)
2011-10-11 20:09 <DocScrutinizer> err
2011-10-11 20:09 <viric> hm.. I don't really see the eyes :)
2011-10-11 20:10 <DocScrutinizer> http://en.wikipedia.org/wiki/Eye_pattern
2011-10-11 20:12 <viric> ah I looked at the qi wiki
2011-10-11 20:12 <viric> I'd never name the wikipedia 'wiki'
2011-10-11 20:12 <viric> :)
2011-10-11 20:15 <DocScrutinizer> fair point, sorry
2011-10-11 20:24 <zrafa> wpwrak: I could not bring it to home. Rain here.. But I found some picture in internet of some scope very similar:
2011-10-11 20:24 <zrafa> http://imagine41.com/catalog/product/gallery/image/1192/id/757/
2011-10-11 20:24 <zrafa> That front is very very similar and the back as well
2011-10-11 20:25 <zrafa> (you can see others pictures with "next" link)
2011-10-11 20:25 <wpwrak> rain ! in neuquen !?! :)
2011-10-11 20:26 <zrafa> wpwrak: in fact.. now I did zoom.. the front is almost exact to the "Noising oscilloscope"
2011-10-11 20:26 <zrafa> wpwrak: special day here :)
2011-10-11 20:27 <zrafa> wpwrak: if you do zoom with the CTRL+mouse whell you will read the labels on front. It is almost identical I would say
2011-10-11 20:28 <zrafa> yes. it is identical. I am sure now :). Now it seems that many have different names.. check the two screws where you put your label with the name of the machine :)
2011-10-11 20:28 <wpwrak> yeah, it's a basic analog scope. as we suspected.
2011-10-11 20:28 <wpwrak> (many names) heh ;-)
2011-10-11 20:58 <kristianpaul> cute :-)
