Infinite work is less work
The first task of last week's Weekly Challenge was to print the first ten strong and weak primes. A prime p n is "strong" if it's larger than the average of its two neighbouring primes ( i.e. p n > (p n-1 +p n+1 )/2 ). A prime is "weak" if it's smaller than the average of its two neighbours.

The lost malloc()
Prompted by another project idea that popped into my mind, I did some Unix archaeology and looked at the original sources . This is the most fun I've ever had reading someone else's code - probably due to the historical significance. But also because of how delightfully approachable it was, compared to modern…

Never patterns, exhaustive matching, and uninhabited types in Rust
One of the long-standing issues that we’ve been wrestling with in Rust is how to integrate the concept of an “uninhabited type” – that is, a type which has no values at all. Uninhabited types are useful to represent the “result” of some computation you know will never execute – for example, if you have to define an…

Multimodal Neurons in Artificial Neural Networks
We’ve discovered neurons in CLIP that respond to the same concept whether presented literally, symbolically, or conceptually. This may explain CLIP’s accuracy in classifying surprising visual renditions of concepts, and is also an important step toward understanding the associations and biases that CLIP and similar…

Branchless Coding in Go
So, I was recently inspired by a coworker’s design to pack what would have been JSON (JavaScript Object Notation) data into a bunch of bit fields in an array of 64-bit elements. Binary arithmetic, bit-packing, and high performance are fun for me, so I thought of some ways to improve it, for learning purposes. Then I…
