The Simplicity of Prolog
Nowadays the most popular programming languages are Python, Javascript, Java, C++, C#, Kotlin and Ruby, and the average programmer is probably familiar with one or more of these languages. It's relatively easy to switch from one to another (barring any framework specific knowledge that may be needed), since they are…

An invalid 68030 instruction accidentally allowed the Mac Classic II to boot
This is the story of how Apple made a mistake in the ROM of the Macintosh Classic II that probably should have prevented it from booting, but instead, miraculously, its Motorola MC68030 CPU accidentally prevented a crash and saved the day by executing an undefined instruction.

The Mythical IO-Bound Rails App
When the topic of Rails performance comes up, it is commonplace to hear that the database is the bottleneck, so Rails applications are IO-bound anyway, hence Ruby performance doesn’t matter that much, and all you need is a healthy dose of concurrency to make your service scale. But how true is this in general?

PhysicsForums and the Dead Internet Theory
An exposé no one will read, about the widespread falsification of user posts in PhysicsForums, a scientific community founded in 2001. This is a microcosm of the death of the human-written Internet.

Little Snitch feature nobody knows about
Little Snitch by Objective Development is the first app that I install on a new Mac. In fact I just bought a new Mac, an M4 MacBook Pro with nano-texture display, and I installed Little Snitch via thumb drive even before connecting the Mac to the internet. While setting up my new Mac, which came with macOS 15.2…

Supercharge SQLite with Ruby Functions
An interesting twist in my recent usage of SQLite was the fact that I noticed my research scripts and the database intertwine more. SQLite is unique in that it really lives in-process, unlike standalone database servers. There is a feature to that which does not get used very frequently, but can be indispensable in…

AI isn't going to kill the software industry
I feel like half of my social media feed is composed of AI grifters saying software developers are not going to make it. Combine that sentiment with some economic headwinds and it's easy to feel like we're all screwed. I think that's bullshit. The best days of our industry lie ahead.

Using the most unhinged AVX-512 instruction to make fastest phrase search algo
Disclaimers before we start For those who don’t want to read/don’t care that much, here are the results. I hope after seeing them you are compelled to read. TL;DR: I wrote a super fast phrase search algorithm using AVX-512 and achieved wins up to 1600x the performance of Meilisearch. The source code can be found here…

Morse Code in Tubular Bells (2021)
A quick look at how the movie The Exorcist from 1973 has links to the late great Alan Turing via Mike Oldfield’s album Tubular Bells, Scotland and Amateur Radio. It’s Halloween so figured why not throw some horror in the mix.

An overview of gradient descent optimization algorithms (2016)
Gradient descent is the preferred way to optimize neural networks and many other machine learning algorithms but is often used as a black box. This post explores how many of the most popular gradient-based optimization algorithms such as Momentum, Adagrad, and Adam actually work.

Shifting Cyber Norms: Microsoft security POST-ing to you
tl;dr: Microsoft and other email security scanners will visit the links in email you transmit, and run the JavaScript in those links, including calls that lead to POSTs going out. This used to be unacceptable, since POSTs have side effects. Yet here we are. This breaks even somewhat sophisticated single-use sign-on /…
