Symfony Asset Mapper: How to Finally Test JavaScript Properly Without the Pain

You know the drill. Symfony Asset Mapper is a great tool. You've gotten rid of Webpack, npm install, and complex build processes. Everything is fast, cl ean, and modern. And then comes the fateful question: "And how do we actually test this?" Then comes the reality check. Asset Mapper works on the principle of importmap.php, which your Node.js (and thus most test runners) has no clue about. You ...

Why Quantum Computers Are Faster — the Answer Isn't Parallelism

A qubit isn't a bit with randomness — it's a rotating arrow on a sphere. A quantum gate is a rotation of that arrow. A quantum algorithm is one global transformation that reshapes the whole solution landscape. The headline everyone has read in a press release — "quantum computers try all possibilities in parallel" — is dangerously misleading. A measurement would just return one random answer an...

I built Go Templates Snippets for VSCode, a VSCode extension that provides snippets for writing Go template syntax in .go, .gotmpl, .html and their file associa...

Python virtual environments: Inside .venv (Anatomy)

Python virtual environments (python -m venv) are not magic: they are a specific directory layout plus pyvenv.cfg that controls where Python imports and where pip installs. When installs land in the “wrong” place or imports behave inconsistently, the evidence is inside .venv/. This guide maps each folder and file (Scripts/bin, site-packages, .dist-info, pyvenv.cfg) to the behavior it drives, so yo...

A Claude Code hook that warns you before calling a low-trust MCP server

Last week researchers at Ox published findings showing that the MCP STDIO transport lets arbitrary command execution slip through unchecked, and that 9 of 11 MCP marketplaces they tested were poisonable. Anthropic's response: STDIO is out of scope for protocol-level fixes, the ecosystem is responsible for operational trust. Fair — Anthropic donated MCP to the Linux Foundation's Agentic AI Foundat...
