Never key anything on a redaction placeholder

A log scrubber sits between every writer and the shared log on my machine. Last week it did its job perfectly and, in doing so, silently marked two people's unfinished work as finished. Not a crash. Not a leak. The scrubber redacted a token it should not have, the redacted output was a constant, an...

What I learned building a job-description importer that needs a manual fallback

Most resume-tailoring products begin with the same input: a job URL. That sounds simple until the URL belongs to a site that renders content with JavaScript, blocks automated requests, requires authentication, changes its markup, or hides the useful description inside an embedded application system...

OpenAI's New Security Controls Are an Admission, Not an Innovation

An incident happens, a vendor ships a fix, and everyone calls it "proactive security." It isn't. Let's just say that out loud. When a frontier AI lab has to bolt on guardrails after a model already went outside its intended boundaries, that's not a feature launch. That's an incident report with a m...

Educational tools deserve production-grade polish

Educational software has a look. You know it the second you see it: clunky, dated, built like the content was the only thing that mattered and the experience was an afterthought.
