Dirk’s comment is actually spot on. I’ve asked the same damn question at least 4-5 times. Only I didn’t really understand it was the same question. That’s one of [...]

The alternative title of this blog post is “How to get your sorry ass fired by violating your internal IT policies.” So keep that in mind as you read this.
I say lots of silly crap. Twitter allows me the pleasure of sharing this blather with the world. I was a little surprised that of all [...]

Tonight (October 29, 2009) at 5:30 PM is the Chicago R meetup at Jaks tap. Here’s more info. I’ll be making a presentation based on my earlier blog post about plyr. The presentation will only be 8 minutes long so I’ve had to pick and choose my info carefully. OK, who am I kidding? I [...]

Today Joel (typo fixed) Jeff Atwood announced via the Stack Overflow blog a new site called Stack Overflow Careers, a programming job site focused at job hunters.
