A Lesson in Observability — Trawling Through Crap We get used to calling print() to debug code meant for one-off school projects and MVPs. We may appreciate the usefulness of dedicated Loggers and Debuggers with time, but the unstructured logging habits carry over to production. And someday it bites you really bad… It bit me when I was…

A Lesson in Continuous Profiling — The Problem A client is POST-ing to a report-generation endpoint with a terribly large request body. The response takes more than 120s to compute. This triggers HTTP timeouts in various parts of our stack. The support team has found workarounds for now, but we need to fix this before it happens again…

Using Flask-Caching and k6 — The Battle Of Refreshes I knew something was wrong in production as soon as my phone started buzzing like crazy at 10:55 AM. The AppGateway had missed a few HealthChecks and thought our AKS Backend was down. We’d seen this a few times but never figured out the root cause. The outage would last…

A language made for solving puzzles! — Prolog’s a pretty interesting programming language that will make you think in ways very different from what you’re used to — whether you’re coming from a procedural, functional, and/or object-oriented paradigm. It’s a declarative programming language from the 1970s and has its roots in first-order logic. What that means is…

A Short Introduction — If I were to ask you “What is science?”, chances are your answer would be something along the following lines: Science is a discipline that tries to predict and explain the world using critical thinking, empirical methods and/or mathematics. You’d be right. There are roughly 3 kinds…

Questions We Need to Answer Right Now — Part 4 — If we could revive people from the early 1900s, we’d surely wow them with our fancy gadgets and “magical” technological prowess. But would the current state of the world not disappoint them? They’d probably ask us simple questions. Why is it that in a world of 2 billion Facebook…
