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 [...]
Navigating the Directory Stack in ‘bash’
If you’re like me, you spend a lot of time jumping from project to project in a Linux shell. I find that I have to switch back and forth between directories. 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. [...]
Follow up: Google Admits Buzz Was Only Tested Internally

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:
Why Should I Use CPAN?
Why should a program depend on so many external modules when it could implement what it needs itself?
Why Text Editors Matter
A good editor is a very flexible tool. Once you become an expert at it, you can use it to accomplish tasks almost as quickly as you can think of them.
What To Do When Your Mac Is Temporarily Disabled
Last night, my Macbook Pro would not wake up from sleep. After jiggling the mouse and hitting the space bar a few times I powered it down. I powered it back up, and I could hear it booting up, and could feel the hard disk move, but there was nothing on the screen. After a little Googling I suspected the video driver was dead.
