andrupalI'm setting up LTSP for the first time and I'm having login problems on the thin client.   The server auth logs suggest the session was begun, but the client screen just goes black, then shows an X, then returns to the login screen.  I've tried updating the SSH keys...does anyone know how to handle this?12:28
cliebowandrupal..not sure..b ut i think ogra would direct you tyo .xseession-errors..12:29
andrupalCan you translate that into newbiespeak?12:29
cliebowerr..i think in the homedir of the perdson logging in there maay be a file by that name12:30
cliebowthat any better?12:30
andrupalIt seems the user directory is empty...is this normal?12:31
clieboweven with ls -al?12:32
andrupalah12:32
cliebowcheck perms too12:32
andrupalI see "no session managers, no window managers, etc...aborting"12:33
cliebowis this a server install?12:34
cliebowyou DO need a gui desktop12:34
andrupalyes, server install.12:35
andrupalforcing myself to learn command line...painful12:35
cliebowwoud you like to use edubuntu ubuntu kubuntu desktop..icewm?12:35
cliebowany preference?12:35
andrupalNo preference12:35
cliebowthis being edubuntu..why not sudo apt-get install edubuntu-desktop.12:36
andrupalI'm actually using ubuntu with ltsp installed12:36
andrupalthis won't matter will it?12:37
cliebowno..i have deubuntu ubuntu and xubuntu on one machine.i use interchangeably12:37
andrupalso you've pointed me to a GUI for the server...that's helpful!12:38
cliebowyou will havt to check with ofgra to see if there are any server-side permutations to make12:39
cliebowwhen starting from a server install12:39
cliebowfor localdevices and sound to work12:39
andrupalSo the reason xsessions weren't working was because I had no GUI installed on the server?12:39
cliebowi aim to please \0_12:40
andrupalWho is ofgra?12:40
cliebowbut im not always correct..someone usually corrects me12:40
cliebowogra put together aa lot of edubuntu12:40
andrupalOK12:41
cliebowwith a little help from his friends12:41
cliebow8~)12:41
andrupalThanks for tolerating my ignorance...I'm two days into this world!12:41
andrupalSo I probably should have started with an edubuntu distro if I want to do LTSP in a snap?12:42
cliebowwelcome..i was there once meself12:42
cliebowprobably..but think what you will learn..12:42
cliebowyou'll have to be sure you have all services12:43
andrupalYes...aiming to set up a whole school on ltsp...so I need to know all the inner workings of it eventually...12:43
cliebowdhcp..tftp...nfs-kernel-server...portmap12:43
cliebowandrupal, look me up if you like..that is what i do..12:43
cliebowand some of the things i say are true12:44
andrupalHow do I look you up?12:44
cliebowhere12:45
cliebowor #ltsp12:45
cliebowor cliebow at ltsp.org12:45
andrupalOK...you're in Maine?12:46
cliebowyeah12:46
andrupalBeauty of a State.12:46
cliebowim at scholl mon tiues wed12:46
cliebowand on a bot thurs fri sat.12:47
andrupalHow is LTSP working out for you?12:47
cliebowbeen great..Maine education is a mess..so im not progressing much12:48
andrupaltry New York City12:48
cliebowyeah ill bet..12:49
andrupalI'm with a new school startup...trying to get them on board before they go down the Windows road12:49
cliebowif you are using "challenged client machines 4.2 is nice12:49
cliebowbut ltsp5 is coming on quick12:49
andrupalGot to run...be back later.  Wish the wife were more tolerant of this hobby of mine...;)12:50
cliebowheh,,..\12:50

LaserJockhi sbalneav03:04
sbalneavHey LaserJock03:04
sbalneavSo, I've completed about 1/2 the rewrite of ldm in C from python03:04
LaserJockHow's it going up north, eh?03:04
sbalneavI'm logged in on it now.03:04
LaserJockawesome03:05
sbalneavOld ldm time on slow box: 40 seconds.03:05
sbalneavnew ldm time: instantaneous.03:05
LaserJockreally?03:05
sbalneavas soon as X starts up you get the login.03:05
sbalneavyep.03:05
=== sbalneav does happy dance.
LaserJockwow03:05
sbalneavlots more work to do.  But it WORKS03:05
sbalneavPlus, it scripts the password session.03:06
sbalneavso, we'll be able to give error messages03:06
sbalneavhandle expired passwords,03:06
sbalneavetc.03:06
LaserJockyeah, sweet03:06
LaserJockI'll be interesting to see the difference in lines of code03:06
LaserJockI've heard, in general, python code is 5-10 times fewer lines of code03:07
sbalneavsbalneav@edubuntu:~/ldm-0.1/src$ wc *.c *.h03:09
sbalneav   60   138  1105 greeter_iface.c03:09

sbalneav  639  1545 13752 total03:09
sbalneavsbalneav@edubuntu:~/ldm-0.1/src$03:09
sbalneavI think the old ldm's about 150 lines.03:09
sbalneavBy the time I'm done, I'll be up around 1500 lines, methinks.03:09
LaserJockyeah, so about 10 times03:09
LaserJockinteresting03:10
sbalneavIn Python, if you want to have a list, you just go l = ['foo', 'bar', 'baz'] 03:11
sbalneavIn C, youd have to alloc some mem, set up the pointers to the string, etc.03:12
sbalneavIf you want to ADD to the list in python, l.append('Foople')03:12
sbalneavIn C, that's a world of hurt03:12
sbalneavrealloc the space03:12
sbalneavcopy the stuff over,03:13
sbalneavadd the new one,03:13

crimsunehh, C++?04:25
LaserJockyeah?04:26
crimsunif you're using C++, just #include <list>04:26
crimsunor do you mean any general structure containing strings?04:27
LaserJockI mean, there's a lot more for me to think about in C++04:27
crimsunyes, there's much more building of infrastructure, but it's more tolerable than C04:27
LaserJockbut that could be just because I don't really get programming04:27
crimsun[in terms of rapidly getting something off the ground] 04:27
LaserJockpython lets me just do things04:28
crimsunyes, that's why most people enjoy Python04:28
LaserJockI keep reading C++ books, but it's still really difficult for me to read through real code04:29
crimsunmight be a shade easier if you understand some of the biggest differences between Python and C++04:31
crimsunPython is much less procedural than C++04:31
LaserJockI was considering taking a class or something at the uni04:31
LaserJockbut I'm not sure if that'd help if it's just the same stuff as in the books04:32
crimsundepends how you're working through the books.04:32
LaserJockprobably04:32
LaserJockI just read the thing and it makes sense04:33
crimsuna typical C++ curriculum will pace you through syntax, data structures & algorithms, and so on04:33
LaserJockbut then if I read real application code it doesn't make a ton of sense04:33
crimsunah, I see.04:33
crimsunI recommend you start with a diagramming course at the uni, then.04:34
crimsundoesn't have to be programming-based, although that helps04:34
crimsunsome art departments have really good ones04:34
LaserJockhmm, interesting04:34
crimsunessentially, look at using visuals to create structure04:35
crimsunthen look at structures to create methods04:35
crimsunmethods have workflows04:35
crimsunworkflows have patterns04:35
crimsunI don't know how strongly a visual person you are, but for some people it helps to see flowcharts, the programmatic extension being UML diagrams, etc.04:36
crimsuna great many F/LOSS projects don't do this sort of documentation, unfortunately, but it's one of the first things we learned under Fred Brooks04:37
LaserJockinteresting04:39
LaserJockI've not done UML diagrams before04:41
LaserJockbut I can see where that might help me out04:42

juliuxRichEd, right09:06
juliuxRichEd, and the german tv want to make an extra broadcast with them09:07

rockprincessSimonAnibal: good news are that today kicked off my last week at school, so it's time to get some feedback, pupils filled out my feedback sheets and most them thought it was a very good idea installing edubuntu at school. the bad news is that last week i installed edubuntu locally on a few machines at school, (i installed edgy) and then upgraded to feisty....but obviously there was a machine who failed to get all updates, so04:27
rockprincessi fetched them again today,...seemed to work quite well, and then when i restarted the gdm bootsplash was all cryptic with squares instead of letters....weird?!04:27
rockprincessSimonAnibal: I tried a few things, such as installing the german language-pack-de and installing localeconf and reconfiguring it...04:33
