"Weedout" Courses Considered Harmful

"The Perils of JavaSchools", by Joel Spolsky, is a wonderfully fun read for students of computer science. A veritable demigod of the software world tells a story -- ringing with appealing truth throughout -- of a tragic fall from grace in modern CS curricula...and at its core, that great deluder Java.

It's relentlessly snarky, and feels relentlessly true, as it lays out in gruesome detail the extent to which kids nowadays are being coddled and left tragically unprepared for the big scary world where pointer arithmetic, abstraction, and recursion are inescapable necessities. It's hard to read it without coming away with the sense that Spolsky has hit upon the great uncomfortable truth in computer science -- that some curricula simply fail to properly train young minds in key concepts.

It's a fun read.

But it's got some problems.

Though I am loathe to disagree with such a titan of my field, I respectfully submit that Spolsky not only misses the broad point of a computer science education,

Scariness and Self-Selection: A Shopping-Week Meditation

nb: For those outside of the Harvard ecosystem, "shopping week" is the first week of classes, during which all courses are open to drop-ins. It's only at the end of shopping week that we submit study cards and are assigned final schedules.

One of the things that inevitably happens during shopping week is that classes are overfull. Since almost all students shop weakly more courses than they end up taking, even classes with correctly-sized rooms end up crowded, short on chairs, and/or with students sitting on the floor.

I've noticed that this problem is remarkably bad in upper-level CS / Math / Stat courses (it might also be bad everywhere else; I just don't have enough data to say). Once you get past the intro-programming and intro-theory sequences, concentrators have almost-infinite freedom in selecting technical electives in the department, so there's a lot of comparison-shopping going around.

To make it worse, a phenomenon I'll dub "window-shopping" is particularly egregious in the CS department -- in-the-know concentrators will show

Yes, you should hire college-educated computer scientists

Daniel Gelernter, CEO of Dittach, has a WSJ op-ed titled "Why I’m Not Looking to Hire Computer-Science Majors":

The thing I look for in a developer is a longtime love of coding -- people who taught themselves to code in high school and still can't get enough of it...

The thing I don't look for in a developer is a degree in computer science. University computer science departments are in miserable shape: 10 years behind in a field that changes every 10 minutes. Computer science departments prepare their students for academic or research careers and spurn jobs that actually pay money. They teach students how to design an operating system, but not how to work with a real, live development team.

There isn't a single course in iPhone or Android development in the computer science departments of Yale or Princeton. Harvard has one, but you can’t make a good developer in one term. So if a college graduate has the coding skills that tech startups need,
