I'm having trouble unedrstanding the two comments on this answer, does anybody know what he's saying?
You can easily limit the amount of processes that can be spawned in Ubuntu and most other Linux distributions by adding this line into /etc/security/limits.conf
sudoedit /etc/security/limits.conf
Then add this line to the bottom of that file
* hard nproc 800
You can raise this to...
If you only have 512 RAM 2,000 will probably dump your machine
We actually did benchmark tests on a few Ubuntu servers (and CentOS servers) to find out how long and how many procs would appears from a bash forkbomb before the server went down
@StefanoPalazzo On 64GB Ubuntu server 85,000 processes were spawned and it took 129 seconds to bring down the server for Ubuntu
@ecoologic It's no problem - you mean load xorg xserver?
@StefanoPalazzo I'll have to go back through my documents to see if I can find the spreadsheet with the results on it. We ended up running this test about 80 times for each machine
Your question inspired me to play around with this.
First I got an image from the webcam, and from the image calculated the brightness by getting the arithmetic mean of the each of the pixels colour values:
import opencv
from opencv import highgui

If anybody thinks openleaks is 'bad', I'll just ask them what it's done to harm them. And if they don't happen to be the leader of the communist party in backwardistan, I expect they reply 'nothing' :P That's my cynical political comment for the day (:
their introductory video is pretty boring..
@MJB, you can go ahead and answer your question right away, no need to wait. people here seem to appreciate this sort of thing
When I open a terminal it shows something like dave@daves:~$ or dave@daves:~/Desktop$. I don't want the dave@daves to show up. Can this be modified to show only the time or something simple like a DOS prompt?
July 11, 2006 will bring a close to Extended Support for Windows 98, Windows 98 Second Edition, and Windows Me as part of the Microsoft Lifecycle Policy. Microsoft will retire public and technical support, including security updates, by this date.
win I heard windows 98 EOS was happening in two years I panicked, because I didn't think there was any way in the world that I was ever going to be able to afford to upgrade my operating system lol
@MarcoCeppi are you aware of an issue in ubuntu gnome where you mouse-over any tab (eg. the move to another workspace option when you right click an item in task bar) and it won't activate the submenu until you leave the button and mouse-over it again?
@MarcoCeppi I'd appreciate that. This is a fresh install (about 1 week old), ubuntu 10.10 fully updated. I had ignored it but now it is getting more and more frustrating
@Tom I wasn't able to replicate that functionality on my 10.10 clean install. I also don't recall this being an issue for an of the other Ubuntu machines I run. This may very well be a bug
Although to move things to a work station I usually just do Ctrl + Shift + Alt + Arrow Keys
which will shift workspace and move the current window
I'm new to this, so excuse my noobish questions. I like the solution from askubuntu.com/questions/23517/… but I'd like to add a way to map it to a key (for quicker use). I'm unsure to edit it (it's a small piece of code, and a little explanation) or to rewrite it. What would you do @TheX?
Small problem I need expedited help with: I moved from a standard 60gig SATA SSD to a PCI-E 120GIG SSD (uses dmraid-0 to bind them). I didn't fancy a reinstall so I dd'd the data across and reinstalled grub. Everything went fine and works except one thing. Before the move, I had about 10 gigs of free space on my 60gigs. On the new drive, I have the same. Something in the copy has made it look like I have twice as many files as I really do.
The disk usage tool shows the real amount of files I have (around 50gig) and shows the real free space... But nothing else does
Is there any way to fix this?
fsck exits and says everything's fine within about half-a-second (which I'm suspicious of)... is there a way of making it go through every inode and checking properly?
0m0.016s. It's not doing any real work.
And it's reporting /dev/mapper/sil_acababdfabcf1: clean, 580265/3751936 files, 9160655/14978596 blocks
I'll convert this into a real question but I wanted to know if anybody had any ideas while I'm in a LiveCD environment

@StefanoPalazzo I wish it offered more output. I assume it's still working but it hasn't said anything yet so I've no idea if it's crashed or not. And as it's an SSD, there's no noise feedback either. Very frustrating when you're trying to fix something and nothing lets you know that it's trying to do it for you
Bah! I control-c'd it and it came back with a very passive-aggressive Interrupted at block 59032192
Running it through e2fsck -vc now - That appears to offer some output
When changing a string of text as a part of a patch, how should the translation in the .po files be handled? For example, a recent paper cut I've worked on involved changing the string "Reboot Anyway" to "Restart Anyway" when gnome-session detected applications still running during restart. When ...

Okay round two. Does anybody know how to install grub and have it change the UUID of the disk it thinks it's installed on?
I keep running various grub-install commands from a LiveCD and it's just not changing it in /boot/grub/grub.cfg (I'm assuming menu.lst isn't used anymore because it only has old entries in there for me)
Can't even see where it's pulling the old UUID from (the drive isn't even plugged in anymore)
@Sid @JorgeCastro Yeah that's what I was trying to show you guys earlier soon all the pending edits from users under the 2k rep will show up there for review
In the beginning there weren't that many high rep users who could edit questions. As that number grows I thought I would add some tips/tricks that I use for those of you striving to earn a badge improve the quality of the site.
@StefanoPalazzo @TheX There are two changes. First any registered user can now edit a post. If you're a user under 2k rep then you edit needs to be approved. Any user over 2k can see and approve edits if they are looking at that question/answer. Mods currently have a tab in the review section they can look over all of these but soon that will be available to the 2K+ users
