Hi! I’m Tim, QA Engineer at inDrive. Some time ago, when I was updating tests for new endpoints, one of them behaved strangely.

In August 2011, a data center in Dallas lost power for roughly five hours. The facility had the usual markers of resilience — multiple utility service entrances, backup generators, and UPS systems — yet a single automatic transfer switch failed, and the building went dark anyway.

Ask an AI agent whether a treasury really bought back $50M of its own token and you get a fluent yes, usually with a source that cannot be opened. No block height. No transaction hash. No payload with a timestamp. In a market where money moves on claims, that is the whole problem in one … Read more

You added a cache so an expensive function would run once per key. Then you counted how often it really ran. For 50 keys, it ran about 400 times. The cache works. Every value it returns is correct. It just doesn’t do the one job you gave it. And the usual excuse, “Python has a … Read more

Ten years ago, the standard advice to a computer science student was simple: learn a language, build projects, collect a few frameworks, and apply for junior roles. Junior roles were where people got paid to learn the craft. AI coding agents are putting that ladder under pressure. Today’s tools don’t just autocomplete a line. They … Read more

Every programmer eventually encounters that moment of quiet confusion during a late-night debugging session: you cast a signed 8-bit -1 to hexadecimal, expecting something clean and human-readable, only for the debugger to spit back 0xFF. Widen it to a 32-bit register, and it suddenly balloons into 0xFFFFFFFF. Where did the minus sign go? Why didn’t … Read more

France’s potential role in AI rests on its ability to organise a chain of capabilities.
