Elevators I Have Known, “Why maintaining the elevator should require eleven hours of hammering is something I try not to think about, just as I avoid asking why this particular elevator has to get its inspection certificate stamped each month instead of, say, every three years.”

Answers from John McCarthy, “Here is a VERY rough transcript of the informal interview.”
A Formal Investigation of Diff3, by Sanjeev Khanna, Keshav Kunal, and Benjamin C. Pierce. “We offer a simple, abstract presentation of the diff3 algorithm and investigate its behavior. Despite abundant anecdotal evidence that people find diff3’s behavior intuitive and predictable in practice, character- izing its good properties turns out to be rather delicate: a number of seemingly natural intuitions are incorrect in general.”

A ternary search tree (TST) is a nice and simple data structure which provides a way to store strings in order for fast searching. It also supports more advanced string queries. A TST can be seen as a hybrid between a binary search tree and a digital search trie.
trish2 is a library to handle PATRICIA trees, a structure suited for large dictionary lookups. The library provides C functions to create, search, write and read PATRICIA trees. The tree nodes can be associated to arbitrary data so PATRICIA trees can act as a hash. An executable is also provided for fast search in a list of fixed string patterns.

When seekdir() Won’t Seek to the Right Position, Mark Ballmer has a nice story: “What I found out in the end is a surprise and was not expected: A bug that has been there in all BSDs for almost all the time, since the 4.2BSD times or for roughly 25 years…” (Honestly, I prefered reading the directory directly, like they did in K&R1.)

Wie schreibe ich denn?!
Ganz frei, ganz ohne Bedenken. Nie weiß ich mein Thema vorher, nie denke ich nach. Ich nehme Papier und schreibe. Sogar den Titel schreibe ich so hin und hoffe, es wird sich schon etwas machen, was mit dem Titel im Zusammenhang steht. Man muss sich auf sich verlassen, sich nicht Gewalt antun, sich entsetzlich frei ausleben lassen, hinfliegen –. Was dabei herauskommt, ist sicher das, was wirklich und tief in mir war. Kommt nichts heraus, so war eben nichts wirklich und tief darin und das macht dann auch nichts. — Peter Altenberg

However, despite being in use in both paper and electronic mediums for almost half a century, there is practically no evidence that it actually assists users in this way.”
When something interests us, we play around with it. Sometimes this yields a funny observation; sometimes it doesn’t, but that’s about all there is to it. Once in a while the cartoonist will find himself in a beam of light and angels will appear with a great idea, but not often. — Bill Watterson

Delimited Continuations in Computer Science and Linguistics, a talk by Oleg Kiselyov. “We give a detailed introduction to delimited continuations – the meanings of partial contexts – and point out some of their occurrences in multi-processing, transactions, and non-deterministic computations. After briefly touching on the formalism and the logic of delimited continuations, we concentrate on two their particular uses: placing and retrieving multiple contextual marks (dynamic binding, anaphora) and meta-programming (generating code, generating denotations of interrogative sentences and clauses).”

RapidXml is an attempt to create the fastest XML parser possible, while retaining useability, portability and reasonable[!] W3C compatibility. It is an in-situ parser written in modern C++, with parsing speed approaching that of strlen function executed on the same data. Entire library is contained in a single header file, and requires no building or configuration.

Word War vi is your basic side-scrolling shoot ‘em up ’80s style arcade game. You pilot your “vi”per craft through core memory, rescuing lost .swp files, avoiding OS defenses, and wiping out those memory hogging emacs processes. When all the lost .swp files are rescued, head for the socket which will take you to the next node in the cluster.
jsvi is a vi-clone written in pure javascript and should work in any modern web-browser. Works amazingly well here.

Curry’s paradox, so named for its discoverer, namely Haskell B. Curry, is a paradox within the family of so-called paradoxes of self-reference (or paradoxes of circularity). Unlike the liar and Russell paradoxes Curry’s paradox is negation-free; it may be generated irrespective of one’s theory of negation.

Keyboard Calligraphy, the history of Arabic typesetting.
Beluga: Functional Programming with Higher-Order Abstract Syntax, “Our main interest in this project is to investigate programming and reasoning with data structures that provide support for binders. Many object languages include binding constructs, and it is striking that functional languages still lack direct support for binders and common tricky operations such as renaming, capture-avoiding substitution, and fresh name generation.”

Pure is a functional programming language based on term rewriting. It has a modern syntax featuring curried function applications, lexical closures and equational definitions with pattern matching, and thus is somewhat similar to languages of the Haskell and ML variety. But Pure is also a very dynamic and reflective language, and is more like Lisp in this respect. The interpreter has an LLVM backend to do JIT compilation, hence programs run blazingly fast and interfacing to C modules is easy. This guy is reading my mind!
