I went to install Linux (Debian) on an old Asus socket 775 motherboard (a P5LD2) and had a litany of problems getting my installation media to boot. Here’s how I finally got it installed. First, I created a bootable USB

A really bad remote code execution bug surfaced yesterday, in Bash–the GNU replacement for the Unix shell. If you have a webserver running, or possibly just SSH, it can be used to execute arbitrary code. It affects anything Unixy–Linux, BSD, Mac

A few months ago I bought a Gigabyte GA-Z77M-D3H to learn computer forensics on, because at the time I thought that was the direction my career was going. I dropped it into a neglected Compaq case and installed Linux on

I picked up a Celeron G1610 CPU last week and I’m using it to build a Linux box. Yeah, it’s a Celeron. But it performs like a 2011-vintage Core i3 or a 2010-vintage Core i5, consumes less power than either,

Here’s a nice Linux tool: checkrestart

I ran my site through Google Page Speed on Tuesday, and scored a surprising 88 out of 100–higher than I expected. Getting above 90 is going to take some optimizations on files that WordPress updates may change, so I’m hesitant

If your web server is slow and you want to fix it, it’s nice to be able to quantify what you got. Enter Apachebench, which is part of Apache and probably already on your server. The Apachebench caveat Usage is

I got my new 64-bit web server up and running today. Now the main task that remains is to get my data moved over to it. I talked myself into going with an Apache setup, since one program I want
