Customizing the MediaWiki Toolbar Signature
One reason I enjoy the world of open source so much is that if I want something to be a certain way, I can make it be that way if I spend enough time. As an example, I use MediaWiki as a simple blog. It allows me to easily make an entry without much fuss. […]

Getting Rid of WordPress Comments Off
Perhaps you can override this; however, if you want a quick hack to not display “Comments Off” on WordPress blogs that you don’t have comments on, find these lines in wp-includes/comment-template.php: if ( false === $zero ) $zero = __( ‘No Comments’ ); if ( false === $one ) $one = __( ‘1 Comment’ ); […]
OpenBSD 2.9
BSD is often a good choice for utility boxes running stuff like Sendmail or BIND. The hardware support isn’t as good, and if you think desktop applications are bad with Linux, then you certainly aren’t going to like BSD. BSD is arguably more secure and stable than Linux. In the gradient of stability, though, Linux […]
Using Eterm Remotely with Clipboard on OS X
I have a GNU/Linux box running CentOS that is up all of the time, and is my main workstation. Lately, I’ve needed to use a laptop, and am running OS X Tiger on it. I’ve always enjoyed Eterm, but getting this to run on OS X is difficult. Since I mainly work on remote servers […]

Xcode is Required for Nmap and Fink
Both Fink and Nmap have problems compiling with earlier versions of Xcode. Xcode is found here.

Installing Apache 2.2 on Mac OS X From Source
Apache 2.2 compiles perfectly on Mac OS X. We are running an Intel Mac Version 10.5.6. Let’s create a place to compile this that is separate from other software.

Updating the Flash PROM on Sun Ultra 2 Systems
We have a dualie 300 Mhz Sun Ultra 2 that couldn’t run 64 bit apps because the system firmware was so old. It turns out that not only does Sun have good documentation for this procedure, but that our system was even easier to upgrade than the documentation stated. Here are the details of our […]
Software RAID w/ Solaris
The Solaris Management Console (smc) comes with the Solaris 9 distribution, and allows you to configure your software RAID, among other things. We are running the console remotely, so to run smc on our workstation we have to run: # /usr/X11R6/bin/xhost +10.50.100.50 On the Sun box: # export DISPLAY=srv-1:0.0 # smc Of course, your IP […]
Bringing Up a Base GCC Compiler on Solaris 9
