Confessions of a programmer: I hate code review (2010)
Most of the projects I've been working on today have fairly strict code review policies. My work requires code review on most of our code, and as we bring on an army of interns for the summer, I've been responsible for reviewing lots of code. Additionally, about five months ago BarnOwl, the console-based IM client I…

Soup – Alan Kay on Objects
As I listen to “Soup” by Can I’m reminded of the time when Alan Kay took some time to post on Hacker News addressing his thoughts and ideas about object-oriented programming. For raw context read the original thread, but in this post I’ll attempt to annotate some of what was posted. For the purpose of this post…

Playing Mortal Kombat with TensorFlow.js
While experimenting with enhancements of the prediction model of Guess.js, I started looking at deep learning. I’ve focused mainly on recurrent neural networks (RNNs), specifically LSTM because of their “unreasonable effectiveness” in the domain of Guess.js. In the same time, I started playing with convolutional…

End-to-end implementation of a machine learning pipeline (2017)
In the fall of 2016, I was a Teaching Fellow (Harvard's version of TA) for the graduate class on "Advanced Topics in Data Science (CS209/109)" at Harvard University. I was in-charge of designing the class project given to the students, and this tutorial has been built on top of the project I designed for the class.

Towards fearless SIMD
SIMD is a powerful performance technique, and is especially valuable in signal and image processing applications. I will be using it very extensively in my synthesizer, and also it’s increasingly used in xi-editor to optimize string comparisons and similar primitives.

Multithreading Rust and Wasm
When WebAssembly was first shipped it was an MVP which, while minimal, has spawned a huge number of exciting projects which work today across all major browsers. Rust has capitalized on the wasm MVP’s success as well with tools like wasm-bindgen and wasm-pack by making the MVP feel less minimal. WebAssembly is yet…

Advanced techniques to implement fast hash tables
Array and hash table are probably the most important data structures. Some programming languages such as Perl, Lua and Javascript, almost build the language core on top of the two data structures. …

WebAssembly’s post-MVP future
People have a misconception—they think that the WebAssembly that landed in browsers back in 2017—is the final version. In fact, we still have many use cases to unlock, from heavy-weight ...

Validating UTF-8 bytes using only 0.45 cycles per byte (AVX edition)
When receiving bytes from the network, we often assume that they are unicode strings, encoded using something called UTF-8. Sadly, not all streams of bytes are valid UTF-8. So we need to check the strings. It is probably a good idea to optimize this problem as much as possible. In earlier work, we showed that ……

Microservices Are Something You Grow Into, Not Begin With
Let's talk about when it might be a good or bad idea to start using microservices. SPOILER ALERT: it's not the same for every project.
