I'm using an ubuntu 10.04 OS and am looking to install Rubymine. It seems every walk through recommends installing sun-java6-jre before downloading rubymine but aptitude and apt-get are returning nothing, claiming that sun-java6-jre no longer exists. I'm completely unfamiliar with how to handle t...
I've got a computer (Intel core i5) with 32bit Linux installed (ubuntu 11.04) and I would like to install a 64bit Linux virtual machine on it so I can test 64bit command-line applications on it. How can I install such 64bit virtual machine on my 32bit system?
I am trying to set up a Linux x86_64 virtual machine on a 32bit Linux computer and I've been told aqemu's Wizard is a good option. I can follow the wizard steps, but when I try to start the virtual machine, I receive a "No boot devices found!" error. Any ideas what might be happening?
I have a multi-threaded C++ app (using pThreads) that processes a massive flat file that works great on Windows - uses all four cores on my puny CPU. Client wants to run the same code on Red Hat on a fire-breathing 64 Xeon CPU machine. So I compile it here (g++), ran it on Ubuntu on VMWare, and c...
The full 2 GB space doesn't get shown as free space even after fully formatting it with mkfs.ext4. Are these some system files which have occupied the space of 129 MB?

The same web site opens fine in the browser.
I have a weird problem. I wrote a script that scans a directory on a samba share (a OpenSUSE server on the LAN) and uses cp to copy certain CSV files to the local Debian server web root at /var/www.
The script works absolutely fine if it encounters one file to copy, but if there are several, wei...
I've tried to install emacs on Ubuntu server 64bit 11.04, but it's complaining about emacs23-common. If I do:

I still see the same problem:

I'm checking arch on a virtualbox (running on ubuntu) before I install it on my machine. I have followed the wiki up until the display driver section. lspci gives:

Is there an easy way (or is it possible at all) to rewrite a TCP package as it leaves the machine?
For example if I run
telnet binfalse.de 22
it will search for an unused port to leave the machine. In this case it's 46576:
root@srv % lsof -i -P -n | grep telnet
telnet 10150 user 3u I...
I am developing a program that is running on multiple machines using MPI.
I have machines on Amazon EC2 where I can start mpirun from one of them (the master).
Everything works as I expect if I ssh to the master machine, then trigger ssh-agent and then ssh-add my_rsa_key.
What I want to do, is...
I was using Emacs, and typed Control+Alt+D in order to run Emacs' "down-list" command. I was dismayed to see, however, that I was instantly logged out; I assume this is some Gnome keyboard shortcut.
I looked under System/Preferences/Keyboard shortcuts, and saw nothing pertinent; I then ran gcon...
I was trying to quickly edit an .hgignore file from the Cygwin bash shell today, and I added a line that was a mistake. I'm not sure if this was the best way to do it, but I quickly thought of using head -1 .hgignore to remove the offending line (I had previously only had one line in the file). S...
I use debian 6.0 squeeze with xfce.
My problem -some programs look nice and some sort of ugly. AFAIK this is because XFCE is gtk and most programs use gtk theme, but some programs use qt and thus don't use gtk themes (rocket science right there).
So - my question is - how can I apply some the...
There are several ways. One of the easiest is to install squid. Squid is simply a web/FTP cache, but that means it will cache your Debian downloads--as well as any web sites. So it has an added bonus!
One drawback of using squid (or any caching proxy server) is that your sources.list must all ...
I have an irssi session running in my VPS. I connect to it via irssi-proxy using Xchat on my laptop or Andchat on my Android phone. Is there any way I can make it send all messages containing my nick since my last proxy connection to my client when I connect?
My command line/bash fu is extremely weak, but I'm trying to hone my abilities. Hopefully someone can help.
I wrote a super simple expect script so that I can SSH in to a headless box we're using at work, while also sending in the password (for reasons that I am unable to expand upon, we can't ...
hi i've posted the same on superuser to no avail.

Is it possible, using linux permission scheme, to allow users create files but not edit or delete them at a later time? I mean, we have a delivery folder where users put artifacts there and we do not want these artifacts to be modified after delivered i.e. edited or deleted.
Eval'ing backticks? Is there something I don't know or did this editor think they were changing the markdown formatting: unix.stackexchange.com/revisions/10751/2
@Caleb No, the editor only put the proper markdown formatting. The backticks weren't showing in the original because of markdown, but the shell snippet in the original post was fine.
@Gilles Yes. The diff color coding in the revision log was entirely mis-leading. I didn't check the way the original markdown was formatted, I see what happened now.
@Caleb The diff tends to assume that the markdown was correct but the text changed. Which is often the wrong way round. But then you have the source diff.
@Gilles Ya I get it. It would be much more useful for me to see a real diff between the markdown source instead of a diff between html outputs. I've made this mistake before.
I'm trying to automate creating vhosts on my computer. This is merely a learning experience for bash scripting. I'm currently novice. I'm trying to learn more about awk, sed.
No, this isn't homework. I work full-time.
Anyways, this is my conf file. What would be the most efficient way to find a...
This blog thing is a crack up tho. I just found the google doc used by the SuperUser crew to organize their blog topics, who's doing what, what the publish procedure is, etc. It's literally world editable. Meanwhile the security.se folks are chatting about how to have an authorized chain of people that have to approve posts on certain topics.

@Tshepang Um, I don't think that says that U&L is the preferred short monker, only that Gilles sometimes uses it and that perhaps capitalizing Unix.SE is a good way of disambiguating it from the tld for a country Jeff Atwood doesn't think exists.
@Tshepang Michael has given a few reasons. The general unsuitedness of the medium also comes to mind. Meta is QnA, not draft publishing or polling software.
@Caleb I was thinking that since we already have a good platform for peer review (voting, editing, commenting), we might as well stretch its use beyond mere Q&A.
instead of using yet-another-service like Google docs
@Tshepang The system we have is only a good one because it follows strict guidelines about acceptable usage. As a case in point off-topic questions get promptly closed. That's what the system is for. If you try to use it for something else it won't be any good for what it's supposed to do.
