X (Twitter) Media Streaming dekonstruiert: Architektur eines Hochleistungs-Video-Extractors mit HLS und FFmpeg

Einführung Für Entwickler ist die Extraktion von Mediendaten aus großen Plattformen oft eine Lektion in moderner Web-Infrastruktur. X (ehemals Twitter) hat seine Medienbereitstellung von einfachen statischen MP4-Links zu einer hochkomplexen Dynamic Adaptive Streaming (DASH/HLS) Architektur weiterentwickelt. Um Benutzern eine verlustfreie Archivierung zu ermöglichen, habe ich den Twitter...

ASCII to Diagram: Turn AI Text Diagrams Into Shareable Visuals

ASCII to diagram becomes useful the moment an AI coding assistant gives you something technically correct but socially awkward to share: a block of monospace boxes and arrows that makes sense in the terminal, but not in a team doc. I run into this a lot when I ask an assistant to explain a codebase. The explanation is often good. The ASCII text diagram is often good too. But if I want to drop tha...

Unlimited PTO Doesn't Fix Burnout — Here's What Actually Does

Every year, another wave of companies announces unlimited PTO as their answer to employee burnout. Every year, their engineers burn out anyway. Burnout isn't a vacation problem. Burnout is not a rest deficit Burnout is classified by the WHO as an occupational phenomenon resulting from chronic workplace stress that hasn't been successfully managed. The key word is chronic. And the key...

Solving the Gemini API Challenge Lab on Vertex AI: Text, Function Calling & Video Understanding

The "Explore Generative AI with the Gemini API in Vertex AI: Challenge Lab" on Google Cloud Skills Boost throws three Gemini capabilities at you in one sitting: a raw REST call from Cloud Shell, function calling from a Jupyter notebook, and multimodal video analysis. None of it is hard once you know what the verifier is actually checking — but a couple of things are easy to get wrong on the first ...

How to model Lambda cold-start behaviour under spike traffic before you deploy

There is a class of AWS incident I have started calling the "everything looked fine in testing" failure. The pattern is consistent. You design a serverless API. Lambda function with sensible defaults, wired through API Gateway, pointing at DynamoDB. You test it in dev throughout the week. Latency is acceptable. Costs track to plan. Then a campaign drops, or a new enterprise customer brings their ...

Open Brane Annotated: 8 Columns, 80-Line Write Path, One SQLite File

Yesterday I open-sourced Open Brane — a personal event-log brain with one SQLite table, one write path, and an MCP server agents can query. This post walks through how it works. If you haven't read the first post, the short version: every source you care about gets normalized into one append-only table. That table is the source of truth. Every downstream view — Obsidian pages, vector search, comp...

Solana vs Cardano: Real Tradeoffs for 2026 Builders

If you’re weighing solana vs cardano, you’re not alone: the debate keeps resurfacing because the two chains optimize for very different things—speed and UX on one side, methodical engineering and governance on the other. In crypto, that choice isn’t academic; it determines what breaks first (throughput, decentralization, developer velocity, or user costs) when your app actually gets users. ...

4 open-source tools to build production-ready AI voice agents 🎙️🚀

TL;DR: We built this because we kept hitting the same frustrations. You've got only two choices today. One, you pay a platform fee to any of the 300+ voice AI companies for a comfy UI. Or you build directly on Dograh, Pipecat or LiveKit, where every prompt tweak means a code change and a redeployment. For anyone shipping for clients or any production use case, that's a constant bottleneck. We wan...

A 3.7 KB Othello Engine: Bitboards in Rust, Raw WASM, No wasm-bindgen

Othello legal-move generation is seven lines of bitboard bitwise ops. I knew this existed; I'd never actually written it. So I built a Reversi engine in Rust, compiled it to raw WebAssembly without wasm-bindgen, and ended up with a 3.7 KB .wasm that plays a credible game against you in the browser. 📦 GitHub: https://github.com/sen-ltd/reversi-wasm 🔗 Demo: https://sen.ltd/portfolio/reversi-was...
