Version 0.5 of DRef, the definition reifier, is now available.

Classical literate programming A literate program intersperses narrative and code chunks.

Thanks to Paul A.

At ELS 2024, I gave a talk on adaptive hashing, which focusses on making general purpose hash tables faster and more robust at the same time.

Version 0.4 of PAX, the documentation system, and DRef, the definition reifier, was released.

Over at argmin.net, Ben Recht is reflecting on Meehl's lectures on the metatheory of science, which is about how science progresses.

Catchy title, innit?

Try, my test anti-framework, has just got light Emacs integration.

DEFSECTION needs to refer to definitions that do not create a first-class object (e.g. stuff like (*DOCUMENT-LINK-TO-HYPERSPEC* VARIABLE)), and since its original release in 2014, a substantial part of PAX dealt with locatives and references, which reify…

PAX got a live documentation browser to make documentation generation a more interactive experience.

I put the sources of the Two-Tailed Averaging paper on github.

In short, comparing fonts at the same font size is almost never the right thing to do.

This is a complement to the Two-Tailed Averaging paper, approached from the direction of what I think is a fairly common technique: averaging checkpoints.

Do or do not.

PAX v0.1 is released.

Ever wished for machine-readable logs and TRACEs, maybe for writing tests or something more fancy?

After more than five years of silence, I may be resurrecting my old blog.

2020-05-03 – Things have changed the during last 5 years.

Bigger because documentation for named-readtables and micmac has been added.

A promise of PAX has always been that it will be easy to generate documentation for different libraries without requiring extensive markup and relying on stable URLs.

I've been cleaning up and documenting MGL for quite some time now, and while it's nowhere near done, a good portion of the code has been overhauled in the process.

I'm getting so used to the M-. plus documentation generation hack that's PAX, that I use it for all new code, which highlighted an issue of with code examples.

I've just committed a major feature to MGL-PAX: the ability to include code examples in docstrings.

Due to the bash security hole that keeps giving, I had to disable gitweb at http://quotenil.com/git/ and move all non-obsolete code over to github.

Actually, I'll only link to the post-mortem I wrote in the forum.

The Higgs Boson contest on Kaggle has ended.

After almost two years without a single competition, last September I decided to enter the Stackoverflow contest on Kaggle.

In addition to the cl-libsvm asdf system, there is now another asdf system in the cl-libsvm library: cl-liblinear that, predictably enough, is a wrapper for liblinear.

This is a short rant on what I consider to be a good puzzle and why the trick 36Cube pulls is rather dirty.

My ISP replaced a Thomson modem with a Cisco EPC3925 modem-router to fix the speed issue I was having.

I've moved to an OfflineIMAP + Gnus setup that's outlined at various places.

It hasn't even been a year yet since I first promised that alpha–beta snippet, and it is already added to Micmac in all its 35 line glory.

While I seem to be unable to make my mind up on a good interface to alpha–beta with a few bells and whistles, I added a Nash equilibrium finder to Micmac, which is becoming less statistics oriented.

I can't believe I won.

First, is it possible to get something as simple as RESOLVE-BATTLE wrong?

Released v0.6 (git, latest tarball).

The Google AI Challenge is back with a new game that's supposed to be much harder than Tron was this spring.

As promised, my UCT implementation is released, albeit somewhat belatedly.

For what has been a fun ride, the official results are now available.

Tron is a fun little game of boxing out the opponent and avoiding crashing into a wall first.

Debian Squeeze finally got Xorg 7.5 instead of the old and dusty 7.4.

From a failed experiment today, I salvaged Micmac, a statistical library wannabe, which for now only has Metropolis-Hastings MCMC and Metropolis Coupled MCMC implemented.

Let me interrupt the flow of the MGL introduction series with a short report on what I learnt playing with Deep Boltzmann Machines.

UPDATE – This post is out of date with regards to current MGL.

UPDATE – This post is out of date with regards to current MGL.

This is going to be the start of an introduction series on the MGL Common Lisp machine learning library.

I'm cleaning up the accumulated junk and found this guide that was written eons ago.

Debian Lenny was released back in February.

Consider a class with a trivial initialization dependency between slots A and B: (defclass super () ((a :initarg :a :reader a) (b :initform 0 :initarg :b :reader b))) (defmethod initialize-instance :after ((super super) &key &allow-other-keys) (setf (s…

A quick note to library implementors: the effects of DECLAIM are permitted to persist after the containing file is compiled, and it is unkind to mutate your user's settings.
