The makers of the E Text Editor have produced a nice Learning Regular Expressions Video Tutorial and Cheatsheet. Although they apply regular expressions within their text editor product, there is lots of knowledge that you can transfer to your scripting/programming endeavors. I think a lot of readers of Digital Media Minute will not particularly have a use for this video tutorial but if you have tried to understand regular expressions and had difficulty doing so, I watched the first few minutes of this 16-minute video and I can vouch for its clear-cut, straightforward approach to regular expressions. They even include  an additional cheat sheet/ quick reference guide.
New Personal Avatar Service
Pavatar is a service much like Gravatar which allows you to provide a personal avatar of yourself that can be used on sites that support the service. Unlike Gravitar which hosts your picture for you, Pavatar relies on your personal picture being hosted on your webspace. There are plugins available for most blogging platforms as well as libraries that you can use to incorporate pavitars into your own applications. It’s funny how almost everybody is becoming a web publisher nowadays, so that you have entire de facto standards and ecosystems created by people who want to improve elements of the entire experience for everyone.
