Build a Typed Training Data Client in TypeScript with intervals-icu

If your training dashboard starts as one HTTP request and grows into athletes, activities, wellness, workouts, gear, and performance data, a hand-written fetch wrapper becomes expensive to maintain. Every new endpoint adds another URL, another response shape, and another place to get authentication or retry behavior wrong. This tutorial shows a small, reproducible path with intervals-icu , an open-source TypeScript client for the Intervals.icu API . The goal is not to build a complete train...

Portable Agent Manifests with Host-Controlled Infrastructure

AI agents often begin as application code: a prompt, a model call, a few tools, and enough control flow to make the first example run. As the agent grows, the definition and the environment tend to collapse into each other. Model configuration lives beside credentials. Tool access is mixed with prompts. Persistence assumes a particular process. Deployment choices become part of the agent itself. That coupling makes an agent harder to inspect, test, move, and recover. We built Clear Ide...

RustForge: A Modular, Adoptable Rust Test-Suite Template

Hey everyone, Whenever I start scaling out a new Rust service or protocol, I always find myself hitting the same wall: testing gets messy fast. You end up juggling basic cargo test unit checks, hacking together ad-hoc integration scripts, and manually setting up coverage tools every single time. I put together RustForge to solve that headache for my own projects, and figured it might save a few of you some time too. It’s a clean, zero-bloat starter template designed to take you from simpl...

My Local AI Stack, Mid-2026: What Survived and What I Dropped

Six months ago I wrote up my local AI setup and a reader bookmarked it, tried to reproduce it last week, and emailed me confused because half of it no longer matched what I actually run. Fair. Stacks rot quietly. So here's the mid-2026 state of mine: what's still earning its place on disk, what I deleted, and where I quietly went back to the cloud. Context for the numbers and opinions below: I do smart contract security work, I run everything on WSL2 on a machine with a modest GPU, and I've b...

xy is very fast and customizable charting library for Python

Sharing this Python plotting lib, hope it is useful. The main selling point is that it's super fast and performant, e.g. can do 10-billion-point OpenStreetMap dataset. Apache 2.0 license. If you're already using matplotlib, should be able to just change the import to get improved performance for a lot of things . It supports styling with CSS. There are some pretty impressive demos on the docs page: https://reflex-staging.dev/docs/xy/ Disclosure: One of the devs is my friend. Comments
