RETRO is fast
When I first read Google’s RETRO paper, I was skeptical. Sure, RETRO models are 25x smaller than the competition, supposedly leading to HUGE savings in training and inference costs.

Look How Big Is My Team
I'm used to getting asked how many employees work at my startup. For most people, it's a quick way to assess a startup's success. Supposedly, the bigger, the better. But does it really reflect success?

What Is Rust's Unsafe? (2019)
I’ve seen a lot of misconceptions around what the unsafe keyword means for the utility and validity of Rust and its marketing as a “safe systems language”. The truth is a lot more complicated than a single pithy tweet can possibly sum up, unfortunately; here it is as I see it.

IPFS and Their Gateways
The InterPlanetary File System (IPFS) is according to the Wikipedia description: "a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system.". It works a little like bittorrent and you typically access content on it using a very long hash in an ipfs:// URL…

Holography without Lasers: Hand-drawn Holograms (1999)
I've stumbled across a technique for drawing holograms directly upon a plastic plate by hand. It sounds impossible, but I've been sitting on the livingroom sofa making holographic images of floating polyhedra, words, 3D starfields, opaque objects, etc. No laser, no isolation table, no darkroom, no expensive film…

How to JIT – An Introduction
When I wrote the introductory article for libjit , I aimed it at programmers who know what JITs are, at least to some extent. I did mention what a JIT is, but only very briefly. The purpose of this article is to provide a better introductory overview of JITing, with code samples that don't rely on any libraries.
