Niklaus Wirth turned 80 this year, and when stumbling on this link on HackerNews, I was reminded that I have had some notes sitting around in my drafts for a long time.
It starts with an Albert Einstein ...
I've been lazy lately... Well, not really, I've been extremely busy, but I ought to have fit this in earlier. It's gotten harder and harder to get done too, since it's now more work since I had to go back and figure out a lot of the reasons for what I'd ...
I tweeted about this, but figured it deserve a more lasting treatment.
If you've ever used Range#min or Range#max you may have inadvertently slowed your code significantly.
Both of those ought to be O(1) - constant time. After all, a Range in Ruby consist of two values, and though you can't ...

You may or may not have seen my recent post where I admitted to more or less having decided to make my compiler project a Ruby compiler. On the downside this means a lot of complexity that may make it harder to follow. On the upside... Well, you get to read ...
Compiler technology is one of my hobbies, most recently satisfied with my project to write a series of post of how to write a (Ruby) compiler in Ruby. Since I really like Ruby, it's natural that I've done a fair amount of thinking about compiling Ruby, and what the problems ...

As always, if you don't know what I'm talking about, take a look at the series.
To see what I've been up to, take a look at the Github ...
As part of my compiler project, one of my imminent decisions is what object model to use, and sine I like Ruby it seemed a good time to go through Ruby and look at the guts of the Ruby object model. If you've dabbled in meta-programming etc. for Ruby this ...
The code as at the end of this part is available here.
A while back I wrote a post about writing a simple operator precedence ...
