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…

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…

steve yegge - tour-de-babel

Tour de Babel Stevey's Drunken Blog Rants™ This is my whirlwind languages tour — the one I was going to write for the Amazon Developers Journal this month, but couldn't find a way to do it that was... presentable. For one thing, I lapse occasionally into coarseness and profanity here, so it

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…

Boolean Blindness

I hate Booleans! But isn’t everything “just bits”? Aren’t computers built from gates? And aren’t gates just the logical connectives? How can a Computer Scientist p…

Five Questions about Language Design

(These are some notes I made for a panel discussion on programming language design at MIT on May 10, 2001.) 1. Programming Languages Are for People. Programming languages are how people talk to computers. The computer would be just as happy speaking any language that was unambiguous. The reason we have high level…
