Developers Should Abandon Agile

No matter what framework or method your management thinks they are applying, learn to work this way: Produce running, tested, working, integrated software every two weeks, every week. Build your skills until you can create a new fully operational version every day, twice a day, multiple times a day. Keep the design of that software clean. As it grows, the… Read more →

Teaching Computer Science: How to Get Top-Notch Teachers in the Classroom

I read something every day where educators and/or elected officials are talking about the importance for our kids, our country, our future, etc., of teaching computer science, the sticking point being an extreme shortage of qualified teachers. A person entering the workforce with a computer science degree is unlikely to go into teaching because of the opportunity cost: they can… Read more →

Teaching Computer Science: The Phones Aren’t Helping You

I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. The way the classes are taught, via an online curriculum, provides a great temptation to kids to get off-task, which they do, usually by entertaining themselves with their phones. They get off-task in other ways too — web surfing, doing homework for… Read more →

Teaching Computer Science: When You Need Help, Ask For Help

I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. It’s a mixed class . . . most of the students are taking AP Computer Science Principles, and about 10 kids just recently started a second-semester Visual Basic class. The VB kids were pretty inquisitive at first but started to get discouraged… Read more →

Teaching Computer Science: Asking for Help

I’m volunteering a couple mornings a week at a local high school, helping out with computer science classes. This morning, in AP Computer Science Principles, the teacher went through an explanation of the hexadecimal number system, then gave an in-class assignment for students to convert their cell phone number to hexadecimal. Not in two parts, 3 digits and 4 digits,… Read more →

Teaching Computer Science: It’s Not Easy to Teach a Subject in Which You Have No Training

A recent issue of Science has an article on the pipeline for computer science teachers . . . The first sentence says, “It’s not easy to teach a subject in which you have no training.” That could be the whole article, really. That’s about all you need to know about the current state of computer science instruction: It’s not easy… Read more →

More Words and Phrases I’m Sick Unto Death Of

Although I can’t claim never to have said these things myself, if I had a dollar for every time I’ve heard someone say either a) “It was working fine 10 minutes ago,” or b) “It works okay on my machine,” I would be comfortably retired by now. Thus spoke The Programmer. Read more →

What Does a Programmer Do?

I was asked to give a talk last week to a high school computer science class on “What Does a Programmer Do?” (I’m indebted to Jim McCarthy for the “lords and ladies of logic” section.)   Programming is problem solving. At the highest level, the problem that programmers solve is that people want to be able to do things with… Read more →

Learn to Code

I’m a programmer . . . Job searches for me go like this: I’m old, I have to compete with people half my age, but I’ve worked in Orange County since forever so I know some people, and I can write good code in interviews, which the majority of programmers who show up for interviews can’t. I was out of… Read more →

Programmer or Parolee?

Our office building is next door to a probation field office . . . I have a game I play in the parking lot each morning: Programmer or Parolee. I spot someone, guess if he’s here for a programming challenge or a meeting with his parole officer, then wait to see if he shows up in our office. If a… Read more →
