PostgreSQL Query Rewriting Techniques The previous articles in this series covered performance problems you fix by adding indexes, restructuring joins, or tuning memory. This one is about the queries where the plan is "fine" — every node is doing something reasonable — but the query itself is asking the wrong question, producing unnecessarily large intermediate results or forcing the planner dow

A LinkedIn recruiter pitched me a remote "Software Engineer at a DEX" project this week. Reasonable comp range, tech stack squarely in my wheelhouse. After a couple of friendly exchanges, she asked me to "review the codebase before the technical interview" and sent me a GitHub repo link plus a Calendly invite for the call. The repo was malware. It didn't get me, but it's something developers shoul
I watched 30 users talk to the same voice agent Same script. Same questions. The only thing I changed was the response latency: 300ms, 500ms, 800ms. At 300ms, people just talked. No awkward pauses, no confusion. One user didn't even realize it was an AI until I told her afterward. At 500ms, something shifted. Users started talking over the agent. They'd ask a question, wait half a second, then r
Harbor cities understand accumulated risk. Cargo moves in quietly. Weather shifts by degrees. One bad assumption can sit unnoticed until it reaches critical mass. Halifax has lived with that kind of memory for more than a century. On December 6, 1917, a collision in Halifax Harbor triggered the largest man-made explosion prior to the atomic bomb, a disaster that directly changed the lives of over
On April 7 Anthropic published technical Mythos report,as well as announced Claude Mythos Preview and Project Glasswing. The claim was that their newest model could autonomously identify and exploit real vulnerabilities in major open-source projects at unprecedented scale. One of Anthropic's public showcase examples was the Linux kernel, which is not some toy repo but the operating system underne
In today's digital landscape, website security isn't just a best practice—it's a necessity. From protecting user data to boosting your SEO, an SSL certificate (Secure Sockets Layer) is non-negotiable. Yet, many domain registrars, including Namecheap, often push users towards paid SSL solutions, despite excellent free alternatives existing. This guide will walk you through how to implement free SSL
Hi everyone! I wanted to share a small project I’ve been working on lately. The premise is simple: every time we share a photo or a document, we inadvertently leak a massive amount of personal data — from home GPS coordinates to camera serial numbers and even the edit history of a PDF. Using "online privacy services" to clean your files always felt like a paradox to me (sending private data to a s
