lala_lala··on Solvingn the Santa Claus concurrency puzzle with a model checker
Looks interesting. Like that the author modeled the failure scenario first before the correct one, it’s instructive. As other commenter pointed, a small typo in the title.
lala_lala··on Reproducing the AWS Outage Race Condition with a Model Checker
Yes, any analysis after an incident has the benefit, and bias, of hindsight.

But I see this post less as an incident analysis and more as an experiment in learning from hindsight. The goal, it seems, isn’t to replay what happened, but to show how formal methods let us model a complex system at a conceptual level, without access to every internal detail, and still reason about where races or inconsistencies could emerge.

lala_lala··on How concurrecy works: A visual guide
As I read it, it felt more like an exploration from state space stand point (and not an example of model checking) which to me sounded quite reasonable. Unusual and intuitive I'd say.
lala_lala··on Python libraries that helped a healthcare startup grow
Thanks for sharing. Is the code still running on Python 2.x or planning on transitioning to Python 3?
lala_lala··on Ask HN: How to learn to write a compiler and interpreter?
It is just that I have a job and a family to support. So I want to create something in whatever time I have. The prospect of engaging myself in myriad of courses sounds dull.

Maybe it's a folly but I am just intrigued by how they work and want to be able to develop them without committing to taking lot of courses.

Does it require any background in CS?
