There is a lot of demand for digital privacy and security advice out there right now and lots of people are giving advice and writing guides. I beg them to do a few things:

1. Be explicit about the threat model your advice is meant for.

Good vibes ONLY.

You don't want bad vibes in "your" code.

Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog This paper presents implementations that match and, where possible, exceed current quantum factorisation records using a VIC-20 8-bit home computer from 1981, an abacus, and a dog. We hope that this ...

One of my students sent me the latest quantum factorization record, and I have to admit: I’m shook. eprint.iacr.org/2025/1237

`is` operator works confusingly with integers - sopython

Did I break crypto?

It's called doubleplusC these days. C++ is so oldspeak.

the β€œC” in β€œCPU” stands for the C Programming Language. CPUs are called that because they are a hardware implementation of the C Abstract Machine as specified by ISO/IEC JTC 1/SC 22/WG 14.

hindenburg guy signing off with this and it just being a link to a DJ set in Bali rather than like, a Marc Andreesen speech is so good. I respect Hindenburg's hustle so much

My new C programming book is slowly taking shape. If you want to learn along, let's start with the basics of control flow:

The bug is still present, in your time, as it was in ours.

The corruption is in a particular location... it increases towards a center... the center of memory corruption is here... of a particular size and shape, and layers of abstraction below us.

What is here is unsafe and out of bounds. This message is a warning about memory corruption.

This is not a place of honor.

β€œAh,’ said Arthur, who β€” for reasons which are unlikely to become clear β€” found himself in attendance at a C++ committee meeting, β€˜this is obviously some strange usage of the word safe that I wasn’t previously aware of.”
