| 01:30.05 | kakashi90 | hello every body: am computer telecommunication student. and i wanna to start a embedded system formation. so please can you tell me what language shall i study and what i need else to be ready? |
| 01:55.16 | ag4ve | c, assembly, or java. take your pick |
| 01:56.14 | ag4ve | but really, if you learn a language or so, additional languages aren't that hard to figure out. so learn anything |
| 01:56.34 | prpplague | ag4ve: hehe, unless you start with basic or logo |
| 01:57.07 | ag4ve | is there a chip that will run basic or logo? |
| 01:57.17 | ag4ve | oh, right, i see |
| 01:58.19 | ag4ve | i don't think basic would even be /bad/ <- *I"M NOT SAYING GOOD*... just not bad |
| 01:59.24 | ag4ve | iirc, basic still has logic, goto, variables and other things that will help with other languages. but, yes, it's shit |
| 01:59.59 | ag4ve | has never looked at logo |
| 02:03.58 | prpplague | ag4ve: going from basic to C is a nightmare |
| 02:04.04 | prpplague | did so when he was young |
| 02:04.42 | ag4ve | prpplague: old fart |
| 02:04.47 | prpplague | indeed |
| 02:05.18 | ag4ve | gets prpplague to get off his lawn :) |
| 02:06.14 | ag4ve | i agree that learning something other than basic is a good idea. |
| 02:06.42 | ag4ve | it's probably the same reason that cobol and c people have different ideas at the right way to do things :) |
| 02:09.24 | kakashi90 | i program with python :) and little bit with C |
| 02:10.15 | ag4ve | so, c runs on *most chips in some (fucked up) form or another |
| 02:10.39 | kakashi90 | but , i wanna to know if i must learn electronic ? |
| 02:11.11 | prpplague | kakashi90: depends on what aspect of embedded development you plan on working on |
| 02:11.55 | kakashi90 | oh i see, like what |
| 02:11.56 | kakashi90 | ?? |
| 02:12.05 | ag4ve | i always spend the 5x+ more on a project board when i start off with a chip because i just want to know how it works and don't want to screw around with possibly getting something wrong |
| 02:12.39 | prpplague | kakashi90: like if you are doing board validation, board bringup, low level hardware drivers |
| 02:12.42 | ag4ve | plus, with most of these newer chips, they're smt, so you're going to have to design a board and order it.... |
| 02:13.31 | ag4ve | how do you design a board when you don't know exactly what you're using the pins for? |
| 02:13.55 | kakashi90 | ah ok :) . me am interested in linux embedded :D for PS3 or Phones |
| 02:14.31 | ag4ve | ps3? :) |
| 02:14.43 | ag4ve | wonders if sony is listening |
| 02:16.05 | kakashi90 | hhh it's just an example ;) |
| 02:16.17 | ag4ve | i think nvidia has tegra dev boards if that's what you want |
| 02:16.34 | prpplague | ag4ve: best to start with a board that is well know and has good support |
| 02:16.41 | prpplague | oops that was for kakashi90 |
| 02:16.50 | prpplague | kakashi90: get something like the beagle or panda to start off |
| 02:17.10 | kakashi90 | ok thanks |
| 02:17.12 | ag4ve | those are expensive as hell iirc, no? |
| 02:17.29 | ag4ve | i would have suggested an avr or other atmel... |
| 02:18.12 | ag4ve | ah, i donno. i'm stuck in assembly land on this nxp, so.... |
| 02:18.55 | ag4ve | well, i sorta put myself in this corner because of not wanting to reverse the linking shit they did in eclipse, but... |
| 02:20.39 | kakashi90 | excuse me but what can these broad do ? and how can i use it? |
| 02:21.21 | ag4ve | they can do damn near whatever you want them to do |
| 02:21.47 | kakashi90 | hh like what |
| 02:21.49 | ag4ve | search youtube. you'll find some stuff |
| 02:22.08 | ag4ve | ummm, lcd art is the coolest |
| 02:22.57 | ag4ve | wifi stuff, gps, process images, whatever.. i don't know, it's 10:20 here, my imagination is gone for the day |
| 02:23.46 | kakashi90 | ok |
| 02:23.51 | ag4ve | ^^ ask tomorrow and you might get more productive answers out of me :) |
| 02:23.59 | kakashi90 | we program on it with C or java |
| 02:24.02 | ag4ve | but, seriously, damn near anything |
| 02:24.10 | ag4ve | eh? |
| 02:25.13 | kakashi90 | we custom it by using C or java ??? because i saw android :p |
| 02:25.43 | ag4ve | we, who? |
| 02:27.22 | kakashi90 | no nothing, i think i must search more , and then ask |
| 02:27.31 | kakashi90 | thank you very much |
| 02:27.34 | kakashi90 | :D |
| 02:27.36 | ag4ve | kakashi90: btw, you can ask #sparkfun for places to find projects and project boards to hack on |
| 02:28.36 | kakashi90 | ok thanks |
| 02:28.44 | ag4ve | if you're wondering /how/ they run java on that stuff, there's a subset of arm that some chips support.... starts with a j.... don't know because i don't use it / care :) |
| 02:29.00 | ag4ve | yep, good timing. have to do some actual work |
| 02:29.18 | kakashi90 | thanks |

| 15:36.35 | landley | prpplague: open source is a very ironic process. |
| 15:36.53 | landley | The way to get famous is to constantly credit everyone else. |
| 15:37.00 | prpplague | landley: hehe, indeed |
| 15:37.13 | landley | The way to become perceived as an authority is to write documentation so everyone else knows as much as you do on the topic. |
| 15:37.30 | prpplague | landley: hehe |
| 15:37.51 | landley | Busybox doesn't build with linux-3.0 (which dropped this morning), and I dunno why. |
| 15:37.57 | landley | Correction: I dunno why it _ever_ worked. |
| 15:38.18 | landley | libbb.h defines its own struct sysinfo, block copied from the headers, for no obvious reason. (REDUNDANT CRAP!) |
| 15:38.32 | landley | And then include/linux/kernel.h defines its own and we get a redefinition error. |
| 15:38.42 | prpplague | doh |
| 15:38.42 | landley | Except the include/linux/kernel.h version has been there SINCE 1992! |
| 15:38.57 | landley | (My git tree, and thus git annotate, goes back to 0.0.1. ) |
| 15:39.39 | landley | I just updated it to 3.0 and did a "git repack -ad" on it, I should upload it to my kernel.org user directory and add it to kernel.org/doc |
| 15:39.51 | landley | It's really darn useful having ALL the history in there... |
| 15:40.19 | landley | Of course I got the scripts to create it (which didn't work, but were fixable) from some french guy mentioned on LWN several years ago. |
| 15:40.26 | landley | I need to track down the reference and credit him. :) |
| 15:42.41 | kergoth | that does sound useful. grafted the repositories? |
| 15:43.29 | kergoth | hmm |
| 15:44.33 | kergoth | I wish tmux supported use of the scroll wheel for accessing the pane scrollback when mouse pane control is enabled |

| 16:05.52 | landley | shrugs |
| 16:06.06 | CosmicPenguin | kergoth: it looks like default binding PgUp will put you into copy mode and start scrolling. I have the same complaint |
| 16:06.43 | landley | Personally I find http://lwn.net/Articles/263562 pretty interesting too, that's a 0.0.1 kernel patched to run under qemu. :) |

| 16:18.49 | landley | Um, you're welcome? |
| 16:19.09 | kergoth | landley: regarding the link to the history script |
| 16:19.16 | landley | Ah. |
| 16:19.39 | landley | I actually have an updated and packed repo that I'm uploading to kernel.org, which is much easier (and internally a touch cleaner) then reproducing it yourself. |
| 16:20.00 | landley | But then running his script, doing a git pull, and then doing "git repack -ad" would accomplish just about the same thing, so... :) |
| 16:20.07 | landley | It'll just take a while. |
| 16:22.01 | kergoth | I really like having the history of projects for some reason. It really irks me when the old stuff doesn't appear to be anywhere. Was trying to track down old sysvinit versions a couple weeks ago, what a pain. so many gaps |

| 16:29.33 | kergoth | CosmicPenguin: works. built tmux from svn trunk, if you do set -gw mode-mouse on, and scroll with the wheel, it enters copy mode and moves. unfortunatelyt itmoves the cursor rather than the screen, but its an improvement. you can also select text to copy into the tmux paste buffer with the mouse |
| 16:30.46 | kergoth | course you still can't middle click paste, but .. |
