Some AI Koans
These are some of the funniest examples of a genre of jokes told at the MIT AI Lab about various noted hackers. The original koans were composed by Danny Hillis, who would later found Connection Machines, Inc. In reading these, it is at least useful to know that Minsky, Sussman, and Drescher are AI researchers of…

The Typestate Pattern in Rust
The typestate pattern is an API design pattern that encodes information about an object’s run-time state in its compile-time type . In particular, an API using the typestate pattern will have:

hacker
1. A person who enjoys exploring the details of programmable systems and how to stretch their capabilities, as opposed to most users, who prefer to learn only the minimum necessary. RFC1392, the Internet Users' Glossary , usefully amplifies this as: A person who delights in having an intimate understanding of the…

PHP: a fractal of bad design
(This article has been translated into Spanish (PDF, with some additions) by Jorge Amado Soria Ramirez — thanks!) Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us

I Knew How To Validate An Email Address Until I Read The RFC
Raise your hand if you know how to validate an email address. For those of you with your hand in the air, put it down quickly before someone sees you. It’s an odd sight to see someone sitting alone at the keyboard raising his or her hand. I was speaking metaphorically.

Code: It’s Trivial
Remember that Stack Overflow thing we’ve been working on? Some commenters on a recent Hacker News article questioned the pricing of Stack Exchange – essentially, a hosted Stack Overflow: Seems really pricey for a relatively simple software like this. Someone write an open source alternative? it looks like something…

The context sensitivity of C's grammar
Context free grammars (CFGs) are a valuable theoretical tool on which the modern compilation theory relies for parsing the code of programming languages. For example, the most popular tool used for parsing – YACC , generates parsers for CFGs. What most people don’t know 1 is that the vast majority of programming…

Prototypal Inheritance
Five years ago I wrote Classical Inheritance in JavaScript ( Chinese Italian Japanese ) . It showed that JavaScript is a class-free, prototypal language, and that it has sufficient expressive power to simulate a classical system. My programming style has evolved since then, as any good programmer's should. I have…

A Million-user Comet Application with Mochiweb, Part 1
In this series I will detail what I found out empirically about how mochiweb performs with lots of open connections, and show how to build a comet application using mochiweb, where each mochiweb connection is registered with a router which dispatches messages to various users. We end up with a working application that…

Using FizzBuzz to Find Developers who Grok Coding
On occasion you meet a developer who seems like a solid programmer. They know their theory, they know their language. They can have a reasonable conversation about programming. But once it comes do…

Bell Labs and CSP Threads
This page is a slice of the history of concurrent programming, focusing on one particular lineage of Hoare's language of communicating sequential processes (CSP) [1] [1a] . Concurrent programming in this style is interesting for reasons not of efficiency but of clarity. That is, it is a widespread mistake to think…

Why Neovim is Better than Vim
I know Vim better than most. Vim was my first real text editor.[1] I used it for years. I helped write the Floobits plugin for Vim. I’ve delved into Vim’s source code to figure out its workings. I e…

Boundaries
This talk is about using simple values (as opposed to complex objects) not just for holding data, but also as the boundaries between components and subsystems. It moves through many topics: functional programming; mutability's relationship to OO; isolated unit testing with and without test doubles; and concurrency, to…

John Resig - Simple JavaScript Inheritance
I’ve been doing a lot of work, lately, with JavaScript inheritance – namely for my work-in-progress JavaScript book – and in doing so have examined a number of different JavaScript classical-inheritance-simulating techniques. Out of all the ones that I’ve looked at I think my favorites were the implementations…
