I’ve upgraded the blog to Wordpress 2.8.6 after I read about the registered user exploits. Also, I’ve dropped the Adsimple theme I was using, and I’m now using a slightly modified Dojo theme. It’s a little easier on the eyes, but it’s still lightweight enough to be fast on mobile broadband connections. Let me know what [...]

I usually set the time zone on my servers to UTC, but that makes it a bit confusing for me when I use irssi. If you have perl support built into irssi, you can run these commands to alter your time zone within irssi only: /load perl /script exec $ENV{'TZ'}='(nameofyourtimezone)'; For example, I’m in Central Time, so [...]

This is not the usual type of post I’d make on this blog, but I’m trying to find a home for a lost dog that my wife found in New Braunfels, TX. More details are on my Posterous blog. ©2009 Racker Hacker. All Rights Reserved..

If you want instant notifications of a direct message on Twitter on your iPhone, you have a few options. You could set up your mobile device to receive SMS messages and get them quickly, but you’re stuck paying for all of those incoming SMS messages.

If you’re using Snow Leopard, you’ll find that the current version of MacFusion refuses to complete a connection to a remote server. You can fix this in two steps: First, quit MacFusion. Second, open System Preferences and then open the MacFUSE pane. [...]

If you use Fedora 11 in a virtualized environment, you may have seen this error recently if you’ve updated to apr-1.3.8-1: [root@f11 ~]# /etc/init.d/httpd start Starting httpd: [Fri Aug 14 17:05:24 2009] [crit] (22)Invalid argument: alloc_listener: ...

On some systems, getting the mysql gem to build can be a little tricky. Fedora 11 x86_64 will require a bit of extra finesse to get the gem installed. First off, ensure that you’ve installed the mysql-devel package: # yum -y install mysql-devel I’ll assume that you already installed the rubygems package. You can install [...]

There are a ton of places on the internet where you can check the public-facing IP for the device you are using. I’ve used plenty of them, but I’ve always wanted one that just returned text. You can get pretty close with checkip.dyndns.org, but there is still HTML in the output: $ curl checkip.dyndns.org Current [...]

I was digging around for Wordpress plugins last night that would allow me to secure the administrative login page for my Wordpress installations. Most of the plugins are only compatible with Wordpress 2.7.x or earlier, so I was a little concerned about them working with Wordpress 2.8.2. Then I stumbled upon the Wordpress documentation that [...]
