Anecdote: For 15 years floppy disk copy protection was fun cat+mouse hackery (Apple2, C64, Amiga; I was friends with the XCopy guys+I did 'Cyclone' hw copier) with lots of clever/complex tricks (sector sync, errors, long tracks, fat tracks, short tracks, 'weak bits' etc etc)...

Fascinating thread

Come check out what we've been working on! C/C++, Rust, Go, Perl, PHP, Python, Java/JVM and Ruby. Kubernetes/docker/whatever. No need for on-host debug symbols or service restarts, and an overhead that's low enough to leave it running all the time, everywhere =)

Arnau (@[email protected]) Halvar Flake That piece from John Conway's "A course in functional analysis" opened my eyes - way too late - back when I was a math student "The human mind resists abstraction unless it first sees the need to abstract" is a very good way to put it

New blog post: Victor Michel takes Prodfiler down into the depths of the Linux memory management system ... to examine "The OOMsday device". prodfiler.com/blog/the-oomsd…

If you like kernel deep dives, you'll like this. Victor Michel did a followup for my demand paging piece, with a performance focus, covering a LOT that I missed. My favorite part: the clever page-table fu that triggers pathological kernel allocation behavior via a top-down scan. 🥋

Mike Freedman's proof of the 4d Poincare conjecture is one of the most daring, inscrutable results in math history. Now, a new book is trying to save it from being forgotten. I cover this decades-long drama in my new piece for Quanta Magazine quantamagazine.org/new-math-book-…

This paper on Monte Carlo simulations absolutely blows my mind. h/t Keegan Ryan
