Finishing Up the Content Spinner

You'll recall that in my last article I shared a long, complex explanation for why spam email catches my attention and intrigues me, perhaps more than it should. Part of it is that I've been involved in email forever—I even wrote one of the most popular old-school email programs back in the day.

The Many Paths to a Solution

A project I'm involved with has made me think about how there are always many solution paths for any given problem in the Linux universe. For this other project, I wanted to cobble together a version of grep that let me specify proper regular expressions without having to worry about the -E flag and get a context for the matches too.

Bash Shell Script: Building Your March Madness Bracket

I must admit that I don't really follow basketball. But, I do like to engage with folks at work, and every spring I've always felt a little left out when my work colleagues fill out their NCAA March Madness basketball brackets.
