Coverage Before Creativity: The RAG Gate That Keeps My Blog Pipeline Honest

The first failure I had to eliminate in the blog pipeline was not a bad paragraph. It was a bad evidence set. The system was finding a few nearby chunks, mistaking density for coverage, and then drafting as if that narrow slice represented the whole repository. That produces text that sounds confident right up until you compare it with the code. The fix was to stop treating topic selection like a ...

The Reward Calibrator That Learns the Shape of Its Own Judgment

I hit the wall when a single noisy signal kept dragging candidate selection around like a shopping cart with one bad wheel. The composite score looked stable on paper, but the moment I watched different weight sets compete on real samples, it became obvious that I was tuning a judgment function by instinct and hoping the surface was kind. The idea behind the calibrator The part that ch...

🚀 I Built a VS Code Extension for Game Developers to Preview Sprites, Spine & GLTF Models Without Leaving the Editor

If you've worked on a game or an interactive web project, you've probably experienced this workflow: Open Aseprite to check a sprite sheet. Open Spine Viewer to preview animations. Open Blender (or another viewer) to inspect a GLTF model. Switch back to VS Code to write code. Repeat... dozens of times a day. As a Senior Game Developer, this constant context switching always interrupted my workfl...

Small in Code. Large in Behavior.

Neuroloq's attachment pipeline turns on one boundary that comes before transcription: whether to treat an upload as document-like at all, and only then which OCR mode should read it. The shape of that decision is the product. The thing Neuroloq is optimizing for is cheap, deterministic, searchable text recovery — not maximum accuracy on every messy upload. If the goal were maximum accuracy on hos...

WHERE $1::timestamptz IS NULL OR "timestamp" > $1

SQL is quite flexible, making it easy to write a single query that works for two situations: one without a parameter and a WHERE clause, and another with a parameter for filtering, all in the same SQL query. For example, I came across a benchmark comparing MongoDB and PostgreSQL that shows how to handle pagination effectively—by avoiding OFFSET and instead using the last value to fetch the next se...

How to tell an ad experiment is unwinnable before you run it

Most experiments that come back "no clear winner" were unwinnable on the day they launched. The data could not resolve an effect that size, and no amount of extra runtime was going to change that. You can find this out in about two minutes, before you spend anything, with one formula and a resampling pass over your own data. Here is the check, in three steps. Step 1. Compute the smalles...

The deadlines are January 1, 2027 for companies and July 1, 2027 for sole traders. If you read something last year that said 2026, that was true until RD-ley 15/2025 moved the whole calendar back twelve months. Software...

From GitHub Issue to Pull Request: Running Claude Code Unattended

You already run Claude Code by hand: copy issues into a prompt, watch it work, check the diff, and if something breaks halfway through, you restart it. This works fine for one task at a time, but it falls apart when you have 10 tasks simultaneously. Claude Code is good at handling routine engineering tasks: bug fixes, dependency bumps, and small features, when the prompt is clear and the task is ...

How to Detect Website Technologies Programmatically in Go

Manually checking what technologies power a website works once or twice. After that it gets slow, repetitive, and impossible to scale. Modern developers skip the manual step and detect tech stacks in code instead. Your program reads a response, pulls out the signals, and tells you what's running. No DevTools, no guesswork. This guide shows how that detection works and how to build it in Go with t...
