Dijkstra's Algorithm
I was at SCNA the other day, and someone approached me about TDD and Dijkstra’s algorithm. He wondered if you could find a sequence of tests that would lead you to the algorithm. This sounded like a fun little exercise, so I decided to give it a try here.

Sometimes Kill -9 Isn't Enough
If there’s one thing to know about distributed systems, it’s that they have to be designed with the expectation of failure. It’s also safe to say that most software these days is, in some form, distributed—whether it’s a database, mobile app, or enterprise SaaS. If you have two different processes talking to each…

Solving Programming Puzzles Without Using Your Brain
This post is a write-up of a solution to part of a programming puzzle I did yesterday. It’s a little different than the usual “solution + theory” approach, though: I’m going to talk about the actual steps you’d need to take to get to the solution (i.e. what to google, what intermediate code looks like, etc.). Often…

Postgres vs. Pinecone
We respond to Pinecone's recent blog post comparing Postgres and Pinecone. We show that Postgres can outperform Pinecone in the same benchmarks Pinecone covered in their article.

Anatomy of Linux Dynamic Libraries
Dynamically linked shared libraries are an important aspect of GNU/Linux. They allow executables to dynamically access external functionality at run time and thereby reduce their overall memory footprint (by bringing functionality in when it's needed). This article investigates the process of creating and using…

The Eudora Email Client Source Code
Electronic mail is one of “killer apps” of networked computing. The ability to quickly send and receive messages without having to be online at the same time created a new form of human communication. By now billions of people have used email.

Optimizers: The Low-Key MVP
The query optimizer is an important part of any analytical database system as it provides considerable performance improvements compared to hand-optimized queries, even as the state of your data changes.

Counting Clojure Code
For better or worse, we count lines of code. We (hopefully) feel a little dirty when we do it, because it's a flawed metric. But we do it . We do it on large codebases and small code snippets . Even badass hacker David Nolen does it .

Time-Travel Debugging for JavaScript/Node.js
Time-traveling in the execution history of a program during debugging enables a developer to precisely track and understand the sequence of statements and program values leading to an error. To provide this functionality to real world developers, we embarked on a two year journey to create a production quality…

Clip: Connecting Text and Images
We’re introducing a neural network called CLIP which efficiently learns visual concepts from natural language supervision. CLIP can be applied to any visual classification benchmark by simply providing the names of the visual categories to be recognized, similar to the “zero-shot” capabilities of GPT-2 and GPT-3.

LLVM internals, part 4: attributes and attribute groups
This is the last post I plan to do on parsing LLVM’s bitcode, at least for a while. I’ll keep working on the various libraries that I’ve started under the mollusc umbrella, but they won’t be accompanied by regular posts anymore — I’d like to refocus on writing smaller, less dense (read: lower-pressure) posts for a…

Erlang: A Generalized TCP Server
In my last few articles about Erlang we've covered the basics of network programming with gen_tcp and Erlang/OTP's gen_server, or generic server, module. Let's combine the two.
