Posted on May 11, 2007 in Graphics Design

John Chow dot Com is a blog that helps you make money online. If you do a review of his blog, he'll link to you so his readers can check you out. There, I said it.

Actually, John Chow really isn't evil, but he is a genius at working the …
Get The Most Out Of Ruby on Rails With Railscasts

Posted on May 11, 2007 in Programming

I recently came across Railscasts via Digital Media Minute (that name might sound familiar thanks to Jim's XHTML Character Entity Reference).

Ryan Bates hosts individual episodes three times a week delivering tips and tricks for Ruby on Rails. Each screencast is less than ten minutes long and requires Quicktime for …

The SlaptiGooglePR Plugin for WordPress adds a Google PageRank column to your Manage Posts subpanel.

Top 5 OS X Command Line Utilities For Administrators

Posted on May 08, 2007 in System Administration

The true beauty of Mac OS X is Darwin, the BSD-based UNIX that runs under the hood of every Mac OS X computer. Having UNIX handy is what attracted me to OS X, and I know plenty of other administrator-types that have followed suit. Every UNIX variant has commands that …

Posted on May 07, 2007 in system_administration

As discussed previously, we're going to enable RFC 1323 Window Scaling and increase the default TCP receive and send windows to 1 MB. By default Windows 2000 and XP do not offer window scaling options, but will accept them if offered by the other side. To make our changes, we'll …

```
sudo ndd -set /dev …

Linux TCP Performance Tuning

Posted on May 04, 2007 in system_administration

If you have been following our TCP Performance Tuning series, you'll know that we want to enable RFC 1323 Window Scaling and increase the TCP window size 1 MB. To do this, we'll add the following lines to /etc/sysctl.conf and issue sudo sysctl -p to apply the changes …
