Tab completion, without writing a completion script

The first post derived a whole command line interface from a client class, and the second turned it into a command that runs from any directory. Both left the same gap in place: the tool knows a great deal that its user does not. order_by is one of four strings. distance_unit is one of two. level is one of five. The client says so in its type hints, and jsonargparse enforces every one of them, to...

Why Browser Games That Look Offline Still Need an Internet Connection

Some browser games feel almost offline. They start quickly, use simple controls, and may continue running even when the network becomes unstable for a moment. That experience can be misleading. A game can look lightweight and self-contained while still depending on the internet for its first load, saved scores, live challenges, leaderboards, analytics, advertisements, authentication, or updated ...

I encoded a 1000-year-old divination system in Go. Every bug was a distinction my types had collapsed.

I spend my day job on cloud platform work — pipelines, idempotent state machines, the usual distributed-systems apparatus. For the last year I've spent evenings on something with no obvious overlap: an engine that computes and reads Zi Wei Dou Shu (紫微斗數), a Chinese astrology system that's been accreting rules since roughly the Song dynasty. It turned out to overlap completely. Not because divinat...

A Linux video player with NVIDIA VFX VSR support (real-time upscaling + frame interpolation, built with an AI coding agent)

Short version of a recent write-up — no full article here, just the pitch. I wanted RTX VSR-class upscaling on Linux, where NVIDIA only opens it to Windows. So an AI coding agent and I built a video player around the NVIDIA Video Effects SDK: real-time AI upscaling + RIFE frame interpolation, wired into a patched libmpv as custom VF filters, with a Qt frontend. Highlights: The models behind R...

Manage State like a Pro: Frontend Edition

AI models write code better and faster than devs, but what AI cannot do reliably for your specific product is make the fundamental system design decisions like: "Where should this piece of data actually live, who owns it, and what happens to the user experience when the network fails, the user refreshes, or a link is shared?" The modern frontend engineer’s primary value has shifted from writin...

AI UX Patterns for User Transparency

Most users won’t integrate what they can’t see and understand. If the AI applications we build are going to become part of their daily lives, users need transparency.

Claude Code with any model: three ways to route it (incl. the 2-minute one)

Claude Code is the best agentic coding interface right now, but out of the box it only talks to Anthropic's API with Anthropic billing. Sometimes you want the same interface with a different brain: Kimi K3 for cheap long sessions, GPT-5.4 to cross-check a plan, Gemini 3.7 Flash for speed, or simply a model that runs on EU infrastructure because your client requires it. There are three ways to do ...

Why We Ship Our Security Webhook Fail-Open

pandocore.io Anything that installs an admission webhook into your cluster puts itself in the critical path of pod creation: service meshes, secret injectors, policy engines, security agents. One field in that config, failurePolicy, decides what happens when the vendor's code goes down. Most install guides don't mention it. The te...

Introducing Concilium: A Multi-Model Method for Hard Problems

One question, several models Concilium is a method for bringing several AI model families to one difficult question. Instead of asking one assistant for a confident answer, it gives models different roles and lets them explore, challenge and extend one another's work. The human remains responsible for the question, the evidence and the final judgment. The model families The ...

Millions of log lines in PHP, at constant memory

Laravel 13, Horizon, PostgreSQL 18. Our product needs to answer a question about a customer's site: which crawler fetched which URL, on which day, and what status code did it get. Not "how many hits yesterday". The cross product. Why not a log analyzer We started with GoAccess, which is an excellent tool, and abandoned it. The reason is worth stating precisely because it is the decisi...

The <geolocation> element lands in Chrome 144

I wired up a scratch page with the new <geolocation> element the morning I read the writeup, and the surprise is how small the markup gets. What used to be a navigator.geolocation.getCurrentPosition(...) dance is now a handful of attributes on a single tag. Per the Piccalilli writeup, <geolocation> ships in Chrome 144+. The element began life as a general-purpose <permission> el...

I built an AI Shopify audit tool, then decided to take it back into my own hands

Most Shopify audit tools give you a polite report. Vetta roasts your store instead and tells you exactly how to fix what's broken. A few weeks ago, I built Vetta an AI-powered tool that audits Shopify stores for conversion issues. Instead of a standard “here are some insights” report, it bluntly calls out where your store is bleeding money, then gives you actual solutions to fix it. I built th...

Go 1.27's SIMD ties with NumPy until the data fits in cache

Go 1.27 shipped a simd package in the standard library. It is experimental and sits behind a flag, and every write-up I found described the API. None of them said when it actually helps. So I measured it against NumPy on the same task: a speaker-search index, 346 thousand vectors of 192 dimensions, 66 million multiplications per query. The answer turned out not to be about Go or NumPy at all. ...

For the past few weekends I've been working on ForgeCMMS, a free, open source and self hosted CMMS, and it finally feels ready to show. If you've never dealt with a CMMS, it's the software maintenance teams use to keep track of physical assets and repairs: factories, buildings, fleets, gyms, hotels, anything with equipment that breaks.
