ARGOS v0.0.1 is live: a digital twin of Kefalonia

Three weeks ago I started building a map that argues back. Today it is public. 🗺️ argos-geo.org/map What you can do: Click any building, road, beach, or POI See travel time to the fire station and nearest ferry port Toggle wildfire risk and flash-flood layers Find the lighthouse nobody asked about (102 minutes, boat-only) The stack: PostGIS + FastAPI + MapLibre GL + PMTiles.

The barcode prefix does not tell you where a product was made

There is a claim about barcodes that circulates every few years, usually attached to a call to boycott something: the first digits tell you which country a product was made in. Scan a jar, read the prefix, learn the origin. It is wrong, and the organisation that issues the numbers says so directly: Since GS1 user companies can manufacture products anywhere in the world, GS1 Prefixes do not iden...

Building an AI Translator Keyboard for iOS and Android: Privacy, Latency, and UX Lessons

Translating a message on a phone often means leaving the conversation, opening a translator, pasting the text, copying the result, and returning to the original app. I wanted to remove that loop. The idea behind AI Translator Keyboard was simple: type in the text field you are already using, tap one translation key, review the result, and send it yourself. The implementation was not simple at a...

3 Ways to Manage Files in CloudShell

So you've probably had to open CloudShell from time to time to poke at something quickly. Say I wanted to test pulling down an artifact from a private CodeArtifact registry. To do that, I'd need to tweak my ~/.npmrc so npm points at the right registry. Which raises the question: what's the best way to edit a file once you're in CloudShell? Let's look at a few options. Using vim I use Neovim btw...

SKILL.md is not a compiler

If you use Cursor long enough, you will watch it ignore a rule you wrote down. You add a SKILL.md. You tell it "no explicit any". You maybe add a hook. It agrees. Then it ships id: any anyway. A comment on a thread about skill files put it cleanly: the model can work around hooks too. That is not a Cursor bug. It is what "the instruction is text" means. What a Skill File Actually Is A SKILL.md ...

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...

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.

Millions of log lines in PHP, at constant memory

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. ...
