SOFTWARE ENGINEERING, IN PRACTICE

Built from curiosity.
Written from experience.

I’m Shreyas, a co-founder and software engineer.
I build systems and write about Rust, operating systems,
and the decisions behind the code.

From a bug to a blog postAn anime-inspired Shreyas investigates duplicate jobs after a timeout. He checks an AI retry suggestion against a server commit whose reply was lost, adds a stable request key and atomic server-side deduplication, and writes up the lesson. A new idea starts the cycle again. retry.trace JOBS POST /jobs → timeout retry → 2 jobs same key → 1 job server: committed; reply lost server: atomic dedup + enqueue timeout + replay FAIL PASS INVARIANT / FIELD NOTES A timeout isn't a rollback. DRAFT SAVED Did it commit? DB? AI Try this? Backoff + retry Already committed? DUPLICATE! ; ?

From Prediction to Action: What an AI Agent Must Verify

Follow one request from tokens and learned weights to a tool call, a database write, and evidence of success—with a probability playground and an animated failure trace.
