Rant

The random rant of the week by mose.

Multiple inheritance simulation

This is a bit twisted. In ruby, as you know, you cannot use multiple inheritance. But the flexibility of the language, especially the metaprogramming aspect, opens the door for some cheating. Check out this code, it tricks it by declaring the first class as the super class and the remaining classes as modules included in that super class. Pretty acrobatic and elegant, imho.

About vaping

Well this has been my burden for 30 years, and I'm not proud of it. But last week it finally ended. I quit smoking. But this was kindof a trick, as it was made possible by switching to vaping. It certainly doesn't solve the nicotine addiction issue, but I'm very happy with this move and hopeful for a gradual freedom.

I also found out that this vaping practice is very geeky. The hardware part is quite elaborate, vaping devices are really neat piece of work, there are a bunch of vendors. The liquidware is also quite a subject of hacking. Technically it's not that hard to do it yourself. Not surprising that I discovered this vaping practice in geeks circles.
