Let’s convert an MP3 file with accompanying CDG to an MP4 video.
In class-based object-oriented programming, when there are classes that appear to share some functionality, this is often a time when people will refactor them into two subclasses of a common base class, avoiding repetition.
For example, in my farm model the Horse class and the Tractor class each implement a pull_plough method. (American readers might prefer pull_plow.) So this method is a candidate to split out into a Hitchable class for Horse and Tractor to each inherit from.
This would have nice benefits for polymorphism. I’ll be able to pass an object to my Farmer which will only need to check that the object inherits from Hitchable rather than having a hard-coded list of classes like Horse and Tractor that it knows are acceptable.

I meant to post this article a couple of weeks ago, but I’ve been very bad at updating my blog recently. The BBC is showing an adaptation of one of Henning Mankell’s Wallander novels tonight.

BBC News has an article claiming that: The new projections suggestion that by 2050, minorities will account for 54% of the [US] population. Ummm… wouldn’t that be 100% then? Minorities set to be US majority
Charlie Brooker on creationism: Darwin’s theory of evolution was simple, beautiful, majestic and awe-inspiring. But because it contradicts the allegorical babblings of a bunch of made-up old books, it’s been under attack since day one. That’s just tough luck for Darwin. If the Bible had contained a passage that claimed gravity is caused by God … Continued
