This should apply to RHEL5 as well, but I haven’t verified yet. The easiest solution I’ve found is to simply install Ruby and it’s dependencies and then install RubyGems from source. I’ve written a small script which installs Ruby and it’s dependencies. It then grabs the RubyGems source tarball and installs Gems from source. As [...]
This is simple, but I always forget how to do it when I need it and it’s hard to find on google for some reason. echo “hi” | mail -s “My Subject” to@someone.com — -f from@someone.com

I just stumbled across a Mozilla Labs project called Personas. It’s light-weight theming for Firefox that can be changed without restarting the browser. After you install Personas, you get a new menu entry Tools->Personas for Firefox, where you can quickly change the persona you are using. From what I can tell, Personas seem to change [...]

I really wanted to see my currently playing music info on my desktop in Conky, but Conky’s documentation shows no mention of any support for [...]
I can’t believe I never saw this before. Sourceforge has an absolutely HUGE list of tips and tricks. There’s hundreds of Linux tips and lots of programming tips as well.
This is really old news, but it’s new news to me because I just noticed this. Daniel Robbins Funtoo site now has some articles on it that he recently created. Right now, he has posted some of the articles that we’ve previously seen on the IBM Developer Works website, but there’s also now a quide [...]
CPAN is great for easily installing and updating Perl modules. I use it all of the time on my servers. It’s a lot easier than managing Perl modules through the systems package manager. The problem is, when you want to install or update a Perl module, it asks you if you want to follow and [...]
Today I had a need to keep the load on a server at 20 for an extended period of time. I was doing this to test notification escalations in Nagios. So, I found a nice little program call cpuburn-in that will load a processor at 100%. It’s just a tarball with an executable and a [...]
