Why Computer Science Doesn’t Matter

Why Computer Science Doesn’t Matter is an essay about the lack of computer science in the educational curriculum today, and what can be done about it. They’ve come up with an interesting, and successful, approach.

[I want] to place computing where it belongs: in the hearts and minds of every single student.

DEFUN08: ACM SIGPLAN 2008 Developer Tracks on Functional Programming

DEFUN 2008 invites functional programmers who know how to solve
problems with functional progamming to give talks and lead tutorials
at the The ICFP Developer Tracks.
We want to know about your favorite programming techniques, powerful
libraries, and engineering approaches you’ve used that the world
should know about and apply to other projects. We want to know how to
be productive using functional programming, write better code, and
avoid common pitfalls.

ICFP08 looks like a lot of fun!

On Functional Programming in Education

Regarding my last post, you should definitely read all of the comments. It is pretty interesting to get everyone’s perspective on the topic (even if it is simply something to the effect of “Sounds like a great idea!”). Take, for example, Dan Friedman‘s comment:

Since I have been teaching functional programming in my undergraduate programming languages course since 1967, I am thrilled that at long last I might be teaching the sanctioned material.

Functional Programming in Education

On May 28-29, 2008 SIGPLan held a workshop on Programming Languages in the Curriculum at Harvard.

to discuss the role of Functional Programming in Education. The results of their efforts are here.
Please have a look, and, per Matthias’ comment, please consider posting your comments (under the “Programming Languages” section)!

Memes are Brainwashing

From Wikipedia:

A meme consists of any unit of cultural information, such as a practice or idea, that gets transmitted verbally or by repeated action from one mind to another.

Whether or not you agree in the validity of memes as a science (I don’t); the term is often used in authoratively in pop culture. They typically represent some bit information, usually in the form of a frequently repeated phrase, that spreads around and around the community. In the programming community, there are plenty. For example, here are a few: “convention over configuration”, “don’t write code just to make the compiler happy”, or “every developer must learn how to program concurrently: it is the future”.
The interesting things about memes are that they often have an element of truth behind them. For example:

  • “Convention over configuration”: Abstract away often repeated work
  • “Don’t write code just to make the compiler happy”: Use the right language for the task at hand
  • “Every developer must learn how to program concurrently: it is the future”: Use the right problem solving approach for the task at hand
  • “[My programming language] is purely functional“: For the type of program I am writing, side-effects are not welcome

The idea of memes is to pass around the interesting idea so that we can all benefit from it. The problem with them, though, is that they don’t. Instead, they sort of pass around a half-truth whose only intention is to further, most probably, some individual’s agenda. For example:

  • Lisp is convention or configuration taken to the extreme, but you never hear anyone saying that (If you hear me saying it, slap me), and they shouldn’t. Ruby on Rails is to Ruby as Struts was to Java; the only and therefore best of its time.
  • “Don’t write code just to make the compiler happy” is pretty silly. Use a statically typed language for a reason. Use dynamically typed language for a reason. There is a difference. You should understand the difference and its impact to your development process.
  • The IEEE, ACM, and nearly every presenter at JavaOne 08 preached fear of the multicore future without expounding on why every developer needs to master multi-core programming (solution looking for a problem?). That said: if every programmer learned how to program really well in the first place, we might not need 64 cores.
  • “Haskell is purely functional, so it is better than all other impure languages”: Please help me, the reader, understand why!

Because memes are half-truths, people often don’t get to the meaty goodness of the truths behind them. Perhaps at some gut-level they know there is a very good truth hiding back there. If, like most people, though, they don’t explore it further, then they will instead assume the meaty truthful goodness to be the ugly, half-truth of the meme. Since the community largely supports the meme; it becomes common knowledge that the individual must accept it in order to keep his place in the community.
Therein lays the danger of memes, whenever the meme is reintroduced, the individual sort of experiences the behavior modification reaction much like a Skinner pigeon; they have to buy into nonsensical statements about which everyone agrees. Sprinkle any article or blog post or discussion with any number of such memes and you have instant gold for making your point unbeatable. It is a strange and disappointing phenomenon that draws into question much of what is written in the tech world today.
Addendum: 12/10/08
Today I fixed typos, revised the grammar, and altered the content to reflect what I actually meant. As such, I believe this to be a “good faith” modification that didn’t merit change-tracking for the reader’s sake.
