Hot summer

Summer has been extremely hot and we have been enjoying it at the fullest. While this meant that I haven’t gotten around writing here as much as usually, I haven’t forgotten the blog.

Solving ToaZZle with CPS

ToaZZle is a game akin to peg solitaire. This blog post talks about how to solve it by using Hy and Stilpo.

Removing HyCons

Next Hy release will remove cons cells from the language. In this post, we’ll have a quick look what they were used for.

Simple Chat Bot

While working on Stilpo, I wrote a simple chat bot. This post takes a look at how it works and how it could be expanded. It’s based on ideas of Paradigms of Artificial Intelligence Programming: Case Studies in Common Lisp by Peter Norvig.

Bitten by Mutability

A cautious tale how having mutable data structure caused a curious bug.

Upcoming Hy: Mangling changes

Upcoming version of Hy will have some changes to how mangling works. This blog post looks at the current state and explains it in high level.

n-queens puzzle solved in hy and cps

In the previous blog posting, I showed a way to solve n-queens puzzle with Tiny Rule Engine. This blog post will look how to solve the same problem with Classical Problem Solver (or CPS for short). Both are modules in Hy library called Stilpo.

Tiny Rule Engine, the Final Post (for now)

This should be the last post in the series about Tiny Rule Engine. I have most of the features down and the part that is left is to actually learn to use them. And what could be a better way than trying our new shiny Tiny Rule Engine than solving n-queens puzzle.

Tiny Rule Engine, part (inc n)

Not too surprisinly, I’m still tinkering with the tiny rule engine. Specifically on how to add some logic into rules.

Tiny Rule Engine and Unification Woes

Work continues with tiny rule engine and I have encountered rather interesting design decision relating to unification, namely uniqueness of values.
