Written by I recently noticed that my /boot partition was at 95% full, so I investigated to see what was causing it. Apparently, it was filling up with older versions of the linux kernel as a result of upgrades. Because my system has been very stable, I decided to keep only the current version of the kernel [...]

Running more than 4GB RAM on Fedora, RHEL, & CentOS
For about a year now, we’ve been happily running two Dell PowerEdge 2950s with quad procs, 4GB of RAM (or so we thought), and RHEL5. Running a high-traffic website can be memory intensive, so we recently decided to upgrade the memory, and bought 8 more GB of RAM for each machine. But, after installing the [...]
READ MORE »Dell Warning: The current memory configuration is not optimal.
In a cabinet in a top secret location somewhere in the Pacific Northwest, I’ve got two Dell PowerEdge 2950s, each with four 2GB DIMMs installed. I purchased four additional 4GB DIMMs to upgrade the memory in both to a total of 16GB, and installed them in the servers last night, so that each server’s DIMM slots [...]

A few months ago, I installed two software upgrades in my 2007 Maserati Quattroporte GT Sport: an enhancement module for the drive-by-wire system, and an ECM peformance chip, both developed and manufactured by Formula Dynamics. They both made huge differences to the car’s performance. Until recently, neither unit had produced any engine fault codes. However, [...]

After successfully setting up a dual boot of Windows 7 (64-bit) and Fedora 12 on my new Dell Studio laptop, I wanted to record some of the tricks that were necessary to get it done.

Because of the consulting work I do for the Department of Defense and the CIA, the security of my personal data is a big deal. So when my benevolent benefactors in Virginia sent me an 8GB Ironkey a little over a year ago as part of their new civilian contractor security protocols, I felt like a [...]

I found this post from darkness very helpful when I moved from an older RHEL to CentOS 5.4 on a Dell PowerEdge 2650 server: http://darkness.codefu.org/wordpress/2006/09/22/247 Adding: i8042.dumbkbd=1 to the kernel command line (it’s in /boot/grub/grub.conf) worked exactly as advertised. Apart from the keyboard input being a bit slow, and not being able to press the [...]

I did it – I upgraded my primary desktop to Windows 7. And yes, when I say “upgrade,” I mean I actually chose the “upgrade” option, because I was already running Vista. So far, so good. I probably wouldn’t have adopted so early (especially on my primary desktop, on which I depend to support my incurable [...]

Got an iPhone? Wanna freak out and impress your iPhone-toting friends? Then you should enable Emoji and send them some Japanese love! What’s Emoji?
