Always Implement toString

Although I’m categorizing this one as really good advice, rather than as a rule, I think it should be viewed as basically a rule. I think it should be a rule in any object-oriented language that supports it natively (Java and Python, for example).

The advice (rule of thumb, say) is to always create a useful implementation of toString when you create a class. It makes your development and maintenance life ever so much better.

I haven’t put nearly the energy into this blog as I have my main blog, Logos Con Carne. My intentions are good, but I never seem to get around to posting here. (It’s certainly not due to lack of interest.)

In an attempt to get more in the habit, I thought I’d write about some simple fun I had recently with a class for calculating polynomials. It was inspired by a lesson from a set of really fun Python tutorial YouTube videos.

Tabs or Spaces?

There are many issues that divide programmers: operating systems and editors being two huge ones. I’ve worked on too many platforms to care much about the first one, but I’m a lifelong gvim user.

One of the lesser dividing issues involves the crucial source coding choice: Tabs or Spaces? The issue is both less and more important these days. Less because editors are very capable; more because Python is popular.

Multiplication Visualized

On my regular blog I just posted about a Japanese visual multiplication method. It’s a cute trick that ties into the notion of grid multiplication techniques. (In general, multiplication techniques are of some interest due to the Mandelbrot set, which requires multiplying large numbers lots of times.)

It turns out code to generate the patterns was a lot easier than I thought it would be. The hardest part was generating the diagonal summing lines.

Last time I showed you the functions necessary for Life — for John Conway’s game of Life, that is. We ended up with a set of functions you can use to generate frames of a Life session.

This time I’ll show you an object-oriented version (a Life class) along with some other tweaks to make things look nicer.

John Conway’s Life

You may have heard that mathematician John Conway died last April. To his everlasting dismay, most people only know him for his “game” of Life (which he considered trivial and inferior to his real mathematical work). Unfortunately for Conway, his Life game is fascinating.

To honor his passing, I whipped up a Python version that I thought I’d share. Python is about the only language I’ve used a lot in which I’ve never implemented Life, so high time I did, right?
