Adding A Grid To Your Websites
The #grid website has a great tool for web designers -it “inserts a layout grid in web pages, allows you to hold it in place, and toggle between displaying it in the foreground or background.” Go to their website and have a look. It’s pretty impressive. Simple, but impressive. I think I’m gonna give this [...]

The Most Dangerous Programming Errors
The Common Weakness Enumeration (CWE) has released their list of Top 25 Most Dangerous Programming Errors. This list and the explanations of the errors are very instructive and should help both novice and expert programmers. If you’re a developer, I strongly urge you to read this document and make sure you understand the concepts it [...]
The Tautline Hitch Knot
If you've ever had to tie a volleyball net or a tent guy line to a stake, you know difficult it is to tie the knot at just the right place to keep the line tight. The tautline hitch knot is perfect for this application.

The bash shell has commands to maintain a stack of directories. I’ve written some functions that use these utilities to make directory navigation easier. [...]

They’ve been known to do extensive usability tests for [...]
Sometimes Testing Isn’t Enough
In the first few days after the release of Google Buzz many people (including myself) criticized Google for exposing their users' private information. This was a couple of weeks after Apple got a lot flak for their unfortunately-named iPad, and the same week that we heard reports of a woman who broke up with her boyfriend after finding some suggestive text messages on his cell phone - messages that came pre-loaded on the phone. I think that all these cases were not caused by a lack testing, but by testing the wrong audience. Let's examine these three cases and see what we can learn from them:

Camera Clock Correction After The Fact
I had this dilemma a few days ago: I had taken almost 4,000 pictures during a vacation 12 months ago. The vacation was in Asia (two continents over), and the time on my camera was wrong. I was importing the pictures into Adobe’s Lightroom, and wanted them to have the correct time just in case [...]
