How to build bootable Debian installation USB media from Windows

Debian 7.0 (Wheezy) came out this weekend, and I want to mess with it. Here’s how I wrote the installation media to a USB thumb drive for it using a Windows box. Because sometimes that’s all you have available to work with. If you prefer another Linux distribution, like Ubuntu or CentOS or Fedora, the same trick will work for them too.

Four simple steps to optimize WordPress

A couple of years ago, I stood up a WordPress server. I made no effort to tune it, let alone turbocharge it, which is a decision I later came to regret. If your site gets more than a few hundred hits per day, you need to tune it. If you want to get more than a few hundred hits per day, you need to tune it because Apache and MySQL’s default settings are by no means one-size-fits-all. And you can never have too much speed. There are two reasons for that: Google favors fast sites over slow sites, and Amazon found that a one-second delay in page load drops traffic by 7 percent.

There’s a lot of advice out there on tuning WordPress, some of which seems to be good, and some of it not so good.

Here are four things that I know work. I run Apache and MySQL under Linux; these tools may run under Windows or OS X too.

How to start over with MySQL in Debian

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 to run (Webtrees) is designed for Apache and its search engine optimization seems to work better under Apache than Nginx. It’s fast anyway; displaying the 17-person family of Andrew Davis McQueen of Leesville, Mo., briefly consumes 2% of the available CPU time in Webtrees with the APC PHP cache installed and enabled. And that should get better, seeing as newer, faster, better versions of both Apache and PHP were released in the last month.

As I built my new 64-bit web server, I messed up MySQL a couple of times. When you break MySQL beyond repair, here’s how to start over with a fresh MySQL install and a fresh /var/lib/mysql without doing a Windows-like reformat and reinstall of the entire operating system:
