Parsing Advances
I find myself writing yet another toy parser, as one does during a Christmas break. It roughly follows Resilient LL Parsing Tutorial. Not because I need resilience, but mostly because I find producing a syntax tree and a collection of diagnostics a more natural fit for the problem than bailing out on the first error.

Monte Carlo Crash Course: Sampling
In the previous chapter, we assumed that we can uniformly randomly sample our domain. However, it’s not obvious how to actually do so—in fact, how can a deterministic computer even generate random numbers? 1

Advent of Code on the Z-Machine
Fantasy consoles like the Pico-8 are a great idea. A fantasy console provides a standardised and portable environment in which developers can explore ideas within creative constraints. The Z-machine , developed by Infocom in 1979, is the earliest fantasy console I know, although this is probably the first time it’s…

Binary modding a water dispenser to save me from pressing a button (2021)
A few months ago, I decided that it’s time I started to become more responsible and to start drinking more water. Unfortunately, the tap water where I live has a very high calcium content, which makes it a lot better when filtered and cooled first. To solve both issues, I picked up a second-hand professional water…

The economics behind "Basic Economy" – A masterclass in price discrimination
Basic Economy fares are ultra-restricted airline tickets that offer a lower base price in exchange for fewer benefits than standard economy class. Introduced by major U.S. carriers in the 2010s, these fares have become a widespread strategy for market segmentation - a textbook example of price discrimination in…

Why does storing 2FA codes in your password manager make sense?
Modern login systems require a second factor (2FA) to log in, in addition to the standard username and password combination. A Time-based one-time password (TOTP) as a 6-digit number is often used. Password managers like [1Password](https://1password.com/), [KeePass (or respective forks)](https://keepass.info/) and…

Why doesn't Apple make a standalone Touch ID?
I finally upgraded to a mechanical keyboard. But because Apple's so protective of their Touch ID hardware, there aren't any mechanical keyboards with that feature built in. But there is a way to hack it. It's incredibly wasteful, and takes a bit more patience than I think most people have, but you basically take an…

Towards a test suite for TOTP codes
Because I'm a massive nerd, I actually try to read specification documents. As I've ranted ad nauseam before, the current TOTP spec is irresponsibly obsolete. The three major implementations of the spec - Google, Apple, and Yubico - all subtly disagree on how it should be implemented. Every other MFA app has their own…
