I have been somewhat lax with blogging lately, because I’ve been too absorbed in playing with too many new things (and busy at work, with real life, and etc). So thought I’d just make a quick list today to share some of the exciting stuff I’ve been finding… [...]

Adding the following snippet to your .emacs file will cause Emacs’ dired mode to omit all files ignored by Git. This only works if you have dired-omit-mode on, which is ordinarily bound to Meta-o. [...]

The Ledger project now has a new mailing list, hosted at Google Groups. This was requested by several users who were not happy with the current web forums being used. Note that you do not have to join the group just to post a question. I’ll be keeping the web forums up for another year or so, but will start [...]

Git has sometimes been described as a versioning file-system which happens to support the underlying notions of version control. And while most people do simply use Git as a version control system, it remains true that it can be used for other tasks as well. For example, if you ever need to store mutating data in a series of snapshots, Git may be just what you need. It’s fast, efficient, and offers a large array of command-line tools for examining and mutating the resulting data store. To support this kind of usage – for the upcoming purpose of maintaining issue tracking data in a Git repository – I’ve created a Python class that wraps Git as a basic shelve object. [...]

Emacs Chess is a fully featured chess client written entirely in Emacs Lisp. You can use it to play against other people on freechess.org, or against popular chess engines like gnuchess and crafty.

Adding a new back-end is trivial. It also comes with a library for inspecting and reasoning about chess positions. [...]

The most notable change from the previous version is that 64-bit mode and experimental threading are no longer supported, since both have been known to have issues on OS X, while the purpose of Ready Lisp is to smoothly introduce Common Lisp to new users.
