Setting up a local cache is a smart idea if you’re going to be running a VM server, whether it be KVM, VirtualBox, or any other option really.

I wrote a post a few years ago that made the digg and reddit homepage saying Experts Exchange should be removed from Google’s search results because they were using a technique called cloaking - hiding their content behind registration and showing a diffe…

I like running VirtualBox headless on my Mac.

This was really useful for me in scripting TextEdit to run my unit tests, as Erlide has been crashing every time I use it. erl -run mymodule myfunc -run init stop -noshell [http://www.trapexit.org/Running_Erlang_Code_From_The_Command_Line](Running Erlang…

Useful stuff. git filter-branch -f --index-filter 'git update-index --remove filename' HEAD git push --force --verbose --dry-run git push --force Slight better version.

I’m working on getting all our servers standardized with puppet to minimize installation and maintenance hassle.

I’ve been trying to get into Python in my spare time, since it’s got such a huge volume of modules and looks like it should be easy to be ripping it up in no time.

I made a post back in December regarding my MacBook Air and a battery life issue.

When you’re in a shell, and you want to do 1 or 2 commands in another brand new shell, but don’t feel like opening a new window, try using a subshell.

I frequently need to get access to a machine behind a firewall to do some web development, but I don’t have a VPN available.

Over three years ago I wrote about how you cannot use a stored procedure in a subquery.

Copy apachectl (or symlink it) to /etc/init.d/httpd, and add these two lines at the end of the comment section: chkconfig: 2345 64 36 description: script for starting and stopping httpd chkconfig –add httpd These commands will now work: service httpd start

To get a quick idea of what ports you have open on your local box, you can use nmap. ~ jhaddad$ nmap localhost Starting Nmap 5.00 ( http://nmap.org ) at 2010-01-05 11:06 PST Interesting ports on localhost (127.0.0.1): Not shown: 499 closed ports, 492 filt…

Over the last 5 years, I’ve read so many articles about how X doesn’t scale.

I finally got fed up enough to look into this.
