I ran into the following warning while trying to install a package from the IUS third-party repository for CentOS:
warning: ius-release-1.0-6.ius.el5.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 9cd4953f.

This was caused because the IUS GPG key was not (correctly) installed. To fix, type:
sudo yum install yum-plugin-replace

This should prompt you to download and install the correct key. Once this is done, the installation of other packages should proceed smoothly.

I'm a big fan of comics and when on Windows, I tend to use CDisplayEx as my preferred reader of choice for .cbr and .cbz files. When on my desktop, I enjoy reading comics in full screen glory. I like each page fitting the entire width of my screen and scroll down the page, if need be, to reach any hidden panels. This allows me to realise the full impact of the art and makes for comfortable viewing.

I was up to no good on mIRC earlier today and found my screen full of message and fserv tabs/windows. While it certainly is fun clicking away at each window and closing it manually, that would only be if I had some sick fascination with RSI. A little digging unearthed a few commands that helped alleviate the process:

I ran into this curious predicament earlier today when I found that the numeric keypad was not working in Kubuntu. Now, I have a KVM setup here and therefore could easily verify that the keyboard itself was working fine. This meant that the problem was a software issue.

I have gotten used to relying on Opera's tab recycle bin feature to reopen closed tabs. However, earlier today, I found myself accidentally closing a tab in Google Chrome, and what's more I had an unfinished forum comment which I had worked on for 20 minutes in said tab. When I saw no recycler icon in the tab bar and no obvious feature in the preferences or options sections, I panicked.

I had to do a clean install of Eclipse today and found myself stuck with a dodgy plug-in (subversive). However, when I went to the Help menu, I did not find any option to uninstall software. IIRC, there was something along the lines of Manage configuration here where you could go to makes changes and uninstall plug-ins.

Over the last few months, I have run through the entire list of episodes for Star Treks TNG, DS9 and Voyager. As you can imagine, not all episodes are very good and some are downright insipid. The following are the rules of thumb that I have arrived at when deciding whether to skip an episode:

Earlier today, I wanted to prefix a number of image files on a server with a 0. If this was on my desktop, I would have simply used a graphical tool such as the excellent Métamorphose. However, in this case, only a command-line was available. While Google threw up a number of bash scripts, I was curious to see if this could be done in a cleaner and more concise manner. Following the excellent reference to sed and more Google magicking, I arrived at

When (re)installing httpd today, I ran into the following error message:

: make_sock: could not bind to address 0.0.0.0:80

I just finished upgrading Eclipse from Galileo to the new Helios release. I performed the upgrade by adding Helios to the software sources list and updating and all seemed to go well. However, when I restarted Eclipse, I got a splash image which indicated that the upgrade had gone through and then ran into the following error message:
Failed to create the Java Virtual Machine
