A couple of people pointed out that in my wednesday post about Go, I completely left out the concurrency stuff! That's what I get for rushing the post - I managed to leave out one of the most interesting...

Sorry for the slow pace of things around here lately; life interferes sometimes. I've mentioned my fathers illness before; things took a drastic change for the worse a week ago, which made things more than a little bit crazy....

Before diving off into real content, the name of my little π-calculus monstrosity has been chosen. As several people recommended in the comments, I'm going to go with Pica. So, today, we're going to take the dive, and start...

Since my post on datatypes for my π-calculus language, I've gotten a bunch of questions from people who (I guess) picked up on the series after the original post where I said that the idea of the series was...

Before moving on, there's one question that I thought was important enough to promote up to the front page, instead of just answering it in the comments. A commenter asked about process replication, !P, wanting to know if it...

There've been questions in the comments about how to use the adder I explained in the last post. That's a darn good question: I can't believe I actually forgot to include that! As a reminder (and a bit of...

Given a calculus, one of the things that I always want to see is how it can do some kind of meaningful computation. The easiest way to do that is to start building numbers and basic arithmetic....

As I did with my first attempt at explaining π-calculus, I think that before getting into any of the deep semantics, it's good to look at a few examples of things you can build with π-calculus. But before getting...

Now that things are settling down a little bit, I wanted to get back to the stuff I was writing about π-calculus. But looking back at what I've already written, I think I did a terrible job of introducing...
