I suspect the current situation is mostly due to timezones and as the west coast wakes up we‘ll see more cities appear there. It’ll probably take a few days until you can deduce anything about hn-users in general from that map. And thanks f

Fun fact: I randomly asked chatgpt to repeat an answer in German yesterday and tomy surprise it just did! Then i continued the conversation (I asked it to be a pretend DM for my first, guided D&D experience) in German and it just worked

What a nice blogpost! I really enjoyed how Bruno leads us through the whole process including his thoughts and strategies to find the code that needs to be modified and how to do it. Luckily the problem - how to get the bytes of a sqlite re

For people who enjoy this article I recommend reading the two-parter “How does SQLite work?” [1] [2] by Julia Evans. It too is an exploration into the inner workings but diving deeper into code. And for those interested in more details on

This is pretty much what I'm going for :). At this point in the project we have an einsum that is slow but works for all cases and supports AD. Next steps are splitting up contractions into pairwise contractions, finding optimal orders

As others mention there's alternative approaches. For someone with a physics background thoughm it's very natural to think of matrix - or rather tensor, i.e. more than two indices - operations with indices - it's how we work

Heya, for standard arrays that are small, the einsum-macro from Einsum.jl can be faster than BLAS. Einsum.jl translates the code simply into three loops and if cache-access patterns (presumably what most of BLAS optimisation is concerned wi
