The expressive power of Lisp has drawbacks.
Doom engine code review
Before studying the iPhone version, it was important for me to understand how Doom engine WAS performing rendition back in 1993. After all the OpenGL port must reuse the same data from the WAD archive. Here are my notes about Doom 1993 renderer, maybe it will help someone to dive in. January 13th, 2010 : Reddit…
Modern Web Applications are Here
Battlefield 3’s Battlelog system is an interesting web application that many of us missed. Here is why it’s amazing and worth a look at.

Thinking about writing your own Python implementation? Congrats, there are plenty out there 1 , but perhaps you have something new to bring to the table. Writing a fast Python is a pretty hard task, and there’s a lot of stuff you need to keep in mind, but if you’re interested in forging ahead, keep reading!
"Another World" (game) Code Review
I spent two weeks reading and reverse engineering further the source code of Another World ("Out Of This World" in North America). I based my work on Gregory Montoir's "binary to C++" initial reverse engineering from the DOS executable. I was amazed to discover an elegant system based on a virtual machine interpreting…
Hitchhiker's Guide to Python
I first heard about The Hitchhiker's Guide to Python at PyCodeConf a few months ago. It's a fantastic idea: open source, community-driven documentation on how to do Python right: everything from how to learn Python, to how to write idiomatic code, to how to distribute your projects, to surveys of best-of-breed open…
Writing Vim Plugins
A while ago I wrote a post about switching back to Vim . Since then I've written two plugins for Vim, one of which has been officially "released".

I Can Crack Your App With Just A Shell (And How To Stop Me)
Hi, I'm Kenneth. I’m a Swiss transplant in San Francisco. I’m an angel investor, and an engineer at AngelList & CSC. Previously, I was co-founder of FreshPay and the architect behind Chartboost. When I'm not working, you can find me either photographing some remote corner of the world, or hacking away on an…
What's In A GIF
We sill start off by walking though the different parts of a GIF file. (The information on this page is primarily drawn from the W3C GIF89a specification .) A GIF file is made up of a bunch of different "blocks" of data. The following diagram shows all of the different types of blocks and where they belong in the…
How can C Programs be so Reliable?
C is, today, a unique programming language. Surprisingly few people can really program in C and yet many of us have quite strong opinions about it. Buffer overflows, stack smashing, integer overflows — C has many well publicised flaws, and these terms are often bandied about confidently, even by those unfamiliar with…
Don't distract new programmers with OOP
It's not about technology for its own sake. It's about being able to implement your ideas.
All Programmers Are Self-Taught
When I was a teenager I played high caliber baseball. I’m competitive to a fault and when I decide I want to be good at something, results usually follow. Now I’m a third year undergrad…

Why Developers Never Use State Machines
Why developers rarely use state machines, seeing them as overkill until it's too late to switch, and what the state_machine gem did for CrowdHired.
10000 things all CS students should do before graduating
It’s Commencement time! So I thought I’d compile a list of 1010 10000 things I believe all ICS students should have done (by themselves) by the time they get their diplomas. With luck, students have come across some of these in courses. Most likely, that won’t happen, so students need to make time for extra-curricular…
Donut math - How donut.c works
There has been a sudden resurgence of interest in my "donut" code from 2006 , and I've had a couple requests to explain this one. It's been five years now, so it's not exactly fresh in my memory, so I will reconstruct it from scratch, in great detail, and hopefully get approximately the same result.
