slog is a simple logging framework for Common Lisp based on the observation that conditions can represent log events.

Metatronic macros are a simple hack which makes it a little easier to write less unhygienic macros in Common Lisp.

It is the business of the future to be dangerous; and it is among the merits of science that it equips the future for its duties. — Alfred North Whitehead

I’ve written two pattern matchers for Common Lisp:

• destructuring-match, or dsm, is a case-style construct which can match destructuring-bind-style lambda lists with a couple of extensions;
• spam, the simple pattern matcher, does not bind variables but lets you match based on assertions about, for instance, the contents of lists.

Both dsm and spam strive to be simple and correct.

Yet another description of macroexpansion in Common Lisp. There is nothing particuarly new here and it partly duplicates some previous articles: I just wanted to rescue the text.

Three days ago I pointed out that the UK government was lying about the influence of the war in Ukraine on UK retail energy prices. Now we have a better idea what that influence might actually be.

The UK government would like you to believe that the recent increases in the rate people pay for energy are due to the war in Ukraine. This is a lie.

They are corrupt, they have done abominable works, there is none that doeth good.

Here’s a simple example of dealing with a naturally circular function definition.

Common Lisp is, I think, a remarkably pleasant language, despite what some people like to say. Here are two small deficiencies, both of which are understandable in terms of the history of CL, and both of which ultimately hurt naïve programmers working in CL.
