Agentic Coding Is Not a Trap: I Answered the Viral HN Post With My Own Production Logs I made the exact mistake that viral post criticizes: I gave an agent an ambiguous task and went to make coffee. Came back 40 minutes later to 23 modified files, three broken tests, and a refactor nobody asked for. I'm not telling this to complain — I'm telling it because that day I started keeping logs of my a
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

Cyber attacks are becoming more frequent and more expensive because criminals are still getting paid. Despite growing awareness, the economics of ransomware still favour attackers. Only 17% of UK organisations hit by ransomware chose to pay, but even among those who do pay, outcomes remain unreliable. According to UK‑wide data, oranisations are now three times more likely to recover from backups

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
Manual content discovery is a core skill in application security testing. Instead of relying only on automated scanners, you can use simple HTTP requests and browser tools to find exposed files, hidden paths, and technology fingerprints. This covers techniques like checking robots.txt, fingerprinting favicons, reading sitemap.xml, inspecting HTTP headers, and spotting framework markers in HTML sou
This section is the map for the rest of the book. The five stages introduced in the 1.1 chapter overview (parse, analyze/rewrite, plan, portal, execute) are traced here through the actual code: which functions implement each stage, and in what order they get called. The mechanics of each of the five stages are unpacked in later chapters. Here, only the skeleton matters: how a backend starts up, ho
