Bob Pendleton is a 60-something year old blogger who has (probably) been programming since before you were born. His blog, thegrumpyprogrammer.com, documents the lessons he’s learned from decades in the technology trenches.

We’ve worked with Pendleton to present his tales in Web comic form. You can find the first installment, What Old Farts Can Teach You, and the second installment, Before Computing Was Cool, in our archives. Here’s the third.
