Hilbert space: Treating functions as vectors
The tools of linear algebra are extremely useful when working in Euclidean space (e.g. \mathbb{R}^3 ). Wouldn’t it be great if we could apply these tools to additional mathematical constructs, such as functions and sequences? Hilbert space allows us to do exactly this - apply linear algebra to functions.

Reverse Engineering Yaesu FT-70D Firmware Encryption
This article dives into my full methodology for reverse engineering the tool mentioned in this article. It's a bit longer but is intended to be accessible to folks who aren't necessarily advanced reverse-engineers.

How Much OpenAI Spends on Inference and Its Revenue Share with Microsoft
EDIT: I am updating this post to reflect that these numbers are based on accrual accounting, meaning that these amounts are from the quarters I am referencing. Anyone telling you otherwise is misinformed. As with my Anthropic exclusive from a few weeks ago, though this feels like a natural premium

The Geometry Behind Normal Maps
Tangent space is often presented as a confusing block of shader math. This is a deep dive into what tangent vectors actually mean, how they emerge from UVs to bridge 2D and 3D space, and the geometry that makes normal mapping possible.

A brief look at FreeBSD
Recently I've been playing around with FreeBSD in a virtual machine. The reason for this is that (if all goes well) some time in December my new Framework laptop will arrive, replacing my current X1 Carbon that is starting to show signs of old age (e.g. a keyboard where certain keys don't always work). Framework in…

Chat Control 2.0 through the back door
Just before a decisive meeting in Brussels, digital rights expert and former Member of the European Parliament Dr. Patrick Breyer is sounding the alarm. Using a "deceptive sleight of hand," a mandatory and expanded Chat Control is being pushed through the back door, in a form even more intrusive tha

I converted a rotary phone into a meeting handset
As you may remember, or completely not know, I have a bit of a fascination with old rotary phones . Occasionally, when people learn about this fascination, they donate their old rotary phones to me, so I have ended up with a small collection.

You will own nothing and be (un)happy
Hi! I'm a raccoon, and this is my trash can :] It's full of my thoughts about the mess of being human. No human is perfect, including me, and that's why we are so fascinating.

A catalog of side effects
Optimizing compilers like to keep track of each IR instruction’s effects. An instruction’s effects vary wildly from having no effects at all, to writing a specific variable, to completely unknown (writing all state).

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…
