@slm - true. I was thinking about the no-nonsense philosophy of UNIX (e.g. rm not having any prompts). I suppose that may be a lesser-known facet, though; I got that from the introduction to UNIX history chapter of Classic Shell Scripting.
The Small is Beautiful philosophy was driven by necessity, and can even be seen in the cryptic and abbreviated names for the various programs: cp (copy), rm (remove), ls (list), cat (catenate), dc (desk calculator), ttt (tic tac toe, a game, Belle in 1980) and ed (line editor). (Many names, like ‘ls’ and ‘pwd’ were literally inherited directly from Multics)
this reminds me that I heard the other day how they broke into the point of sale systems at Target over the xmas break.
the POS systems at major stores run on, you guessed it, windows XP.
This reminded me of a talk where we had several vendors in at Kodak which were pitching RTOS (Real time OSes) and one of them was NT, I remember asking each group the footprint they required and as each went through they were like 200k, 500k, and embedded WinNT? 16MB.
small by today's standards, but w/ smallness you are also building in a degree of protection in what a hacker can do damage wise too 8-)
Not sure this fits in here..
We recently installed Linux Mint Petra on this small-form-factor dell desktop.
The weird thing is, the sound does not work on board, but works on a speaker connected to the audio out. I've checked all details I could about the alsa mixer, sound card mute check etc. ...
> This [the don't be chatty] principle has further implication. In general, Unix tools follow a "you asked for it, you got it" design philosophy. They don't ask "are you sure?" kinds of questions. When a user types rm somefile, the Unix designers figured that he knows what he's doing, and rm, removes the file, no questions asked.
@slm the famous UNIX license plate? the truth-speaking Dilbert comic on UNIX? that presentation means business

@terdon ah, yes. I didn't include the little asterisk after the last sentence that pointed out that rm occasionally prompts when you want it to remove suspicious files, e.g. write-protected files or ...
> * For those who are really worried, the -i option to rm forces rm to prompt for confirmation, and in any case rm prompts for confirmation when asked to remove suspicious files, such as those whose permissions disallow writing. As always, there's a balance to be struck between the extremes of never prompting and always prompting.
I remember being so offended the first time a Linux desktop asked me to confirm a deletion. Must have been when I switched to Gnome from the good 'ole WindowMaker. I was like, huh? Is this Windows now?
@terdon and this is why I don't ever open Nautilus. I use GNOME and I actually like the GNOME Shell but if I'm going to manage files, I'll do so in a real environment (GNOME Terminal), thank you very much
@terdon I'll be moving stuff around in a Cygwin terminal when a friend will walk up and say, "what are you doing?" and I go, "I'm managing some files" and they go "um... so you aren't hacking??" and I go, "no, I'm just managing some files" and they get very confused
@slm great slide deck. I especially liked that it mentioned Plan 9 - <3

@strugee Hah! That's nothing we had a tv crew once in the lab where I did my PhD and they wanted to film us scientists doing science stuff. I was puttering about on the terminal, uploading files for my Dad's webpage on ftp. The journalists loved it and got it all on film :) They were sure I was sequencing DNA or something

@terdon hah. I'm a member of this community called StudentRND, and there was some company that was talking about maybe doing a show on us (don't know where it came from). and we were talking about this in the facebook group and it was determined that what we should do was act super cool on the first day, using tons of terminals, bringing out all the party tricks, etc., and then just be ourselves for the rest of the show
@terdon exactly. I'm all like, "I know C-n seems instead of the down arrow seems weird but it's actually the best keybinding scheme ever" but you can't get it until you try it
Well, I've never been through an emacs tutorial, I've learned by using it and having people tell me how to do things and then reading up on specific tasks. I actually didn't even know about C-n since the down arrow has worked since the 1st emacs I used
I have all sorts of random holes in my emacs knowledge
@slm thanks for the link, looks interesting but I can't confirm since I don't have the symptoms. I have the relevant files on my system and they look as described but that's all I can say.
yup, whether in vim or emacs, i use the arrow keys. If I were to use C- bindings to move around in emacs, I'd use the ergoemacs bindings C-[ijkl] to do it.
:) When I was a virgin (untouched by text editors) I tried both and couldn't get my head around vi modes. I know vim's great and I really should take the time to learn it but I was scared back then
@terdon I tried to follow the instructions here, having discovered Alt/Ctrl/T via Google. The first Removing existing drivers line said it failed, but I pressed on and the second seemed to work, as did the next (very long) line cut&pasted.
...I then downloaded & extracted "the appropriate driver", but the next bit says I have to remember to navigate to where you extracted the driver to beforehand. I can't see how to do that. My cwd was "home" under some long user-specific name, that doesn't contain the "download" folder where the driver is sitting. Also, that terminal window has mysteriously disappeared now, so I'm going to have to reboot...
@FumbleFingers gimme a second to read through what you did
OK, you can open a new terminal with Alt/Ctrl/T again, no need to reboot
If you downloaded through a browser (chrome you said right?), the file should be in /home/fumblefingers/Downloads
You can check by opening a terminal and running :
ls ~/Downloads
@FumbleFingers that should have failed, don't worry about it. It just means you did not actually have the drivers installed. That's just a precaution to make sure the system is cleaned out before installing the new ones.
OK, I'm up to speed now. Do you have a terminal open?
Well, pretty much exactly what I expected has happened. The system wouldn't restart (hung on a blank purple screen). I've just rebooted from the install cd, where its asking if I want to "try" or "install". Should I start all over again? Or is there a quick way in?

Anyway, the process is: i) identify where your system is installed ii) mount it iii) trick your machine into thinking it is running the installed system and iv) continue the installation of your drivers where you left off

Simply copy pasting (middle click) the whole list will run them sequentially
In fact, the second block needs to be pasted together or it will hang (the && means run the next command if the 1st was successful so it will hang unless there is a subsequent command)
(back on xp system) the ubuntu pc seems to be locked up. Dragged title bar of terminal window down, and it became resizeable. Can switch cursor between Firefox and terminal, but can't type. terminal window is stuck on "removing temporary directy ... fglrx-install-xxxxx
I don't know if the SO system will get bothered by this, but I'm now typing on the Ubuntu pc, having successfully closed & killed the stuck terminal window.
I have two Intel Core2 Duo desktop PCs both connected to an iiyama Prolite E2407HDS monitor through a VGA switch box. I've just reformatted the hard drive and installed Ubuntu 12.04 on one.

@FumbleFingers could you post the output of ls in the downloads directory?
@FaheemMitha because this is an ubuntu-specific issue. They have their own system for dealing with the proprietary drivers and ubuntu specific stuff gets migrated.
@FumbleFingers perfect and the .deb files have been generated

My bad actually, the sudo is not needed. I'm copying these commands from an answer of mine but you're already root in this environment and don't actually need the sudo.
@FumbleFingers grrrrr
OK, it should have worked. Theoretically, you'll have a working system upon restarting
back again. After reboot i got a load of message about cant install (whatever), and cant report it either. is it possible ubuntu cant run my video card properly?
I doubt it. Something probably got screwed up somewhere along the line. It might be simpler at this point to reinstall and then follow the same instructions again. I am guessing that any complications arose because we were doing this from the live system.
Can you boot into rescue mode? It should be an option when you fust turn on the machine and get the list oif operating systems
i'm impressed with this level of personal support, but getting worried that ubuntu (all linux?) seems pretty obscure. maybe that's to be expected when i know so little
back again. After reboot i got a load of message about cant install (whatever), and cant report it either. is it possible ubuntu cant run my video card properly?
If you rebooted, chose the 1st option and now have a working system, it sounds like everything is fine. What am I missing?
