Prince Of Persia Code Review
On Apr 17, 2012 Jordan Mechner released the source code of Prince of Persia. Even though it is the Apple II version written in 6502 assembly language, it was a pleasant experience to dive in the code of that mythical game: As usual there were many fascinating sofware wizardries to discover. The Apple II apparent poor…

A byte string library for Rust
bstr is a byte string library for Rust and its 1.0 version has just been released ! It provides string oriented operations on arbitrary sequences of bytes, but is most useful when those bytes are UTF-8. In other words, it provides a string type that is UTF-8 by convention , where as Rust’s built-in string types are…

Finding Free Food with Python
If you live in a major city, there’s a good chance you’ve used (or at least heard of) food delivery services like Postmates, GrubHub, or DoorDash. These services are great for times when I’m behind on groceries or when I’m getting some late night studying in before a big midterm or final. The only problem with these…

Building a Distributed Log from Scratch, Part 1: Storage Mechanics
The log is a totally-ordered, append-only data structure. It’s a powerful yet simple abstraction—a sequence of immutable events. It’s something that programmers have been using for a very long time, perhaps without even realizing it because it’s so simple. Whether it’s application logs, system logs, or access logs…

Uncle Bob and Silver Bullets
A while back I wrote that Robert Martin was ruining software by being too good at programming. That was supposed to be a joke. Since then he’s done his damndest to actually ruin software by telling people they’re doing it wrong. His most recent response where he yells at software correctness was the breaking point for…

How to zero a buffer
Now, we don't want to truly change the observable behaviour of our software — but fortunately the C standard has a more liberal concept of "observable" than most people. In particular, the C standard states that the observable behaviour includes accesses to volatile objects . What is a volatile object, you ask? It is…

How to do distributed locking
As part of the research for my book , I came across an algorithm called Redlock on the Redis website. The algorithm claims to implement fault-tolerant distributed locks (or rather, leases [1]) on top of Redis, and the page asks for feedback from people who are into distributed systems. The algorithm instinctively set…

Async Rust doesn't have to be hard
An article titled Rust Is Hard, Or: The Misery of Mainstream Programming came out today and it's getting a lot of attention. I have a feeling that it's viewed in a wrong context, so I'd like to comment on the issue raised there.

The microservices cargo cult
Microservices are awesome. We know this because of all the success stories that are circulating lately. The news is full of such stories, of people taking large, monolithic codebases, breaking them up, adding HTTP APIs and enjoying all the benefits.

Remember when people tracked bugs?
I've done some well-known bitching about the halfassed and haphazard way that Open Sores projects have handled their bugs in the past, but man, things have only gotten worse since then. I mean, projects used to actually have bug databases. Boy, those were the days. Failing that, developers used to put their email…

The Art of LaTeX: Common mistakes and advice for typesetting proofs
When was the first time you had to use LaTeX? If you are like most people, it was probably suddenly forced upon you during your first math or CS class where you had to start writing proofs, with minimal guidance on how to get started. Unfortunately, this meant that while many people have good operational knowledge of…

Lessons Learned: A Year with a Large AngularJS Project
After a year of working with a large AngularJS project, I thought I’d share a few of the lessons that I learned in the process. Firstly, I love AngularJS. It suits my needs exceedingly well, and I expect it will be my goto for the forseeable future when I need a solid framework for “thick client” single page…
