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

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

| kristianpaul | did gtkperfm ran slow at old days? | 17:46 |
| zrafa | kristianpaul: when you talk about gtk you need to specify exactly which versoin of gtk | 18:01 |
| kristianpaul | yes sorry | 18:04 |
| kristianpaul | but i dont know | 18:04 |
| viric | have you seen the film Moebius? Does the Buenos Aires metro inspire all that as in the film? :) | 18:05 |
| wpwrak | maybe in a few centuries. they're extending the network very very slowly. | 18:07 |
| viric | :) ok | 18:08 |
| zrafa | kristianpaul: gtk1.. which blizzard talks is from 2001 last release | 18:11 |
| zrafa | kristianpaul: and it is really fast for embedded | 18:12 |
| zrafa | kristianpaul: but no gtk2.. IIRC gtk2 uses a lot float p calculations | 18:12 |
| zrafa | kristianpaul: and if you use it for our tiny embedded world you will kill yourself :) | 18:12 |
| zrafa | wpwrak: you there¡? | 18:13 |
| zrafa | wpwrak: I have news.. you would llike to read :) | 18:13 |
| wpwrak | tell me ! :) | 18:14 |
| zrafa | wpwrak: scope: noising model n-220 oscilloscope | 18:15 |
| wpwrak | what does "noising model" mean ? | 18:16 |
| zrafa | Noising is the machine. | 18:17 |
| zrafa | is the name | 18:17 |
| zrafa | or mark | 18:17 |
| wpwrak | oh, i see | 18:17 |
| wpwrak | insteresting choice of name :) | 18:18 |
| wpwrak | seema that all google hits are about de-noising ... | 18:19 |
| wpwrak | is it really exactly "noising" ? | 18:20 |
| zrafa | wpwrak: yes :) .. and I can not find a picture using google images :P | 18:20 |
| zrafa | it is Noising model n-220 oscilloscope | 18:20 |
| zrafa | made in korea | 18:20 |
| wpwrak | can you take a picture ? | 18:21 |
| zrafa | yes, at home. Rodolfo lend me it so I will bring to home | 18:21 |
| steve|m | a scope which has "Noise" in its name.. nice ;) | 18:21 |
| kristianpaul | how many channels it have? | 18:21 |
| kristianpaul | he bring the probes as well? | 18:21 |
| kristianpaul | steve|m: ;) | 18:21 |
| zrafa | kristianpaul: I see ch A and ch B | 18:22 |
| kristianpaul | good | 18:22 |
| kristianpaul | do you recognice any computer-like port on it? | 18:23 |
| wpwrak | does it say something about the analog bandwidth somewhere ? | 18:25 |
| wpwrak | also, does it have a screen ? if yes, LCD or CRT ? | 18:25 |
| kristianpaul | does it turn on? | 18:26 |
| zrafa | wpwrak: I would say CRT | 18:26 |
| wpwrak | does it even work with electricity ? ;-) | 18:26 |
| zrafa | kristianpaul: yes | 18:26 |
| kristianpaul | noce | 18:26 |
| wpwrak | (crt) uh uh ... that's not very promising | 18:26 |
| kristianpaul | s/noce/nice | 18:27 |
| zrafa | you all envy me | 18:27 |
| zrafa | haha | 18:27 |
| wpwrak | 220 may mean 2 channels, 20 MHz. these are quite common characteristics for analog scopes. | 18:28 |
| wpwrak | well, it'll let you see simple signal shapes. it won't help much with analyzing complex digital communications, though. | 18:30 |
| kristianpaul | zrafa: actually sebastien have an analog one too i had read | 18:37 |
| zrafa | wpwrak: I am not sure that I will understand complex digital communications | 18:39 |
| zrafa | wpwrak: so anyway, with a good scope or not I will need a real hand from hw people | 18:39 |
| zrafa | wpwrak: I meant "I am sure that I will not understand ... " :) | 18:40 |
| wpwrak | oh, you'll learn. usb is a very good topic for learning quite a lot :) | 18:45 |
| 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 :) | 19:27 |
| wpwrak | hehe :) | 19:29 |
| wpwrak | congratulations on your first real scope experience ! ;-) | 19:30 |
| zrafa | wpwrak: thanks, but all is from your work . I modified blinkenlights :) | 19:44 |
| zrafa | and rodolfo did the scope part haha | 19:44 |
| DocScrutinizer | classical scopes are useful for analog only | 19:44 |
| DocScrutinizer | where analog includes proper analog signal levels (and shapes, sometimes) on digital lnes | 19:46 |
| DocScrutinizer | lines | 19:46 |
| wpwrak | DocScrutinizer: yeah, you need a dark room and quick eyes to do much with them for non-repetitive signals | 19:47 |
| wpwrak | zrafa: (reused blinkenlights) so you put it to good use. very nice ! :) | 19:47 |
| DocScrutinizer | on a second thought, levels includes the aspects of shapes that can usefully get examined with a scope | 19:47 |
| DocScrutinizer | though -> wiki eyepattern | 19:49 |
| wpwrak | heh, don't get me started :) | 19:49 |
| 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 | 19:51 |
| wpwrak | (that was generated by scripts operating on a long recording of my DSO) | 19:53 |
| DocScrutinizer | wpwrak: isn't averaging over 106 samples somewhat defeating the purpose of an eye pattern? | 20:07 |
| wpwrak | it's not averaging. it's overlaying. | 20:08 |
| DocScrutinizer | oooh | 20:08 |
| viric | why is that called eye pattern? | 20:08 |
| DocScrutinizer | see wiki | 20:08 |
| DocScrutinizer | it "looks like two eyes" | 20:08 |
| viric | There were no results matching the query. | 20:09 |
| DocScrutinizer | esp with sine waves ;-) | 20:09 |
| DocScrutinizer | err | 20:09 |
| viric | hm.. I don't really see the eyes :) | 20:09 |
| DocScrutinizer | http://en.wikipedia.org/wiki/Eye_pattern | 20:10 |
| viric | ah I looked at the qi wiki | 20:12 |
| viric | I'd never name the wikipedia 'wiki' | 20:12 |
| viric | :) | 20:12 |
| DocScrutinizer | fair point, sorry | 20:15 |
| zrafa | wpwrak: I could not bring it to home. Rain here.. But I found some picture in internet of some scope very similar: | 20:24 |
| zrafa | http://imagine41.com/catalog/product/gallery/image/1192/id/757/ | 20:24 |
| zrafa | That front is very very similar and the back as well | 20:24 |
| zrafa | (you can see others pictures with "next" link) | 20:25 |
| wpwrak | rain ! in neuquen !?! :) | 20:25 |
| zrafa | wpwrak: in fact.. now I did zoom.. the front is almost exact to the "Noising oscilloscope" | 20:26 |
| zrafa | wpwrak: special day here :) | 20:26 |
| 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 | 20:27 |
| 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 :) | 20:28 |
| wpwrak | yeah, it's a basic analog scope. as we suspected. | 20:28 |
| wpwrak | (many names) heh ;-) | 20:28 |
| kristianpaul | cute :-) | 20:58 |
