My Asahi M2 MacBook was stolen. It didn't have encryption

Fri, 04/05/2024 - 7:22am

I am going through a hellish experience after leaving my bag in a Glasgow park. My Macbook Pro was inside it and powered off, but the thief who found it has managed to get access to my files and is trying to blackmail me for money to get my data back after they found my email address in the files they have been raking through.

It turns out that even when you have encryption on your MacOS, installing Asahi linux does not actually encrypt the partition it creates.

This is just a word of warning for anyone using Asahi linux, that you shouldn't assume your data to also be encrypted. If your home is burgled, then you can assume all your data is in the hands of the burglar.

Thieves these days certainly know the value of personal data.

Show HN: FMAs Complement – Like 2's Complement but for Matrix Multiplications

Fri, 04/05/2024 - 7:22am

TLDR : A lookup table for matrix multiplications.

Simple description : This is a custom binary number system designed to calculate vector dot products.

Technical description : FMA's complement is a fixed-point representation of binary numbers created — as an alternative to 2’s complement and 1’s complement — to perform the Fused Multiply-Add instruction.

We combine linear algebra and arithmetic codes (from data compression theory) to make a number system great for finding dot products.

Motivation I took a gap year to start a data compression startup (this was a mistake, I know) so I spent the past year working with Arithmetic Coders. I was trying to build a lookup table with random matrices and I saw patterns.

From my year's long experience with data compressors - patterns should NOT exist in random data. I built this because, I could (with reasonable accuracy) estimate dot products using a lookup table.
