I just visited a company in Finland that can turn any transparent surface — windows, glasses, plastic, anything — into a 3D display that perfectly augments what you see behind it. Welcome to Distance . One of the most exciting companies in Europe right now. And they're only two years old. We're not talking about a tiny rectangle in the corner of your windshield. The entire glass becomes your screen. They showed this to Kia's design team. It led to a concept car with a full edge-to-edge 3D windshield that paints navigation onto the actual road, shows you what the car sees, highlights threats, and yes, could theoretically replace every Pepsi billboard with a Coke one. But the defense side is where it gets serious. As a neighbor to Russia, Finland feels the pain of Ukraine very directly. The Distance team wanted to be part of the solution. Their field operator headset gives soldiers jet fighter-grade situational awareness. Any sensor (thermal, infrared, multispectral) overlaid onto what you actually see. Tested in over a dozen field trials with the Finnish army. Driving armored vehicles in arctic conditions in the middle of the night with full 3D perception. The field operator headset effectively allows soldiers to see through smoke, and with extra cameras even behind walls. Some of what they showed us had never been shown publicly before.  And there's more cooking under the hood they couldn't share yet. Two years in. Moving at the speed of light. Welcome to Europe!

I feel like most 3DGS demos I’ve seen are of larger environments and look great until you zoom in to anything, upon which everything dissolves into a radioactive cloud. This on the other hand is the most amazing 3DGS demo I’ve ever seen.

This is agent-ci.dev, it runs the same native GitHub Actions Runner in a container. The difference is the control pane: Which is a local http server. So it never communicates with GitHub.com, because of this we can do all kinds of interesting things: 1. 0ms cache restores (copy on write mounts) 2. pause-and-retry on failures (bash injection in step.) 3. 100% compatible with GH actions. (just a control pane.)

Running GitHub Actions locally never gets old.

TLDR; GH actions, but for agents. ~0ms cache, retry-on-failure, insanely fast. Agents need validation. CI is the last defense. They shouldn't bother you unless everything is green! GH Actions is usually in the top-5 expenses for dev-teams. Add agents to that mix? It'll easily double. It's the wrong tool for the right job: Slow boot, slow cache, retrieving logs is token expensive for agents, the list goes on... So I built a tool with one amazing feature: live-reload for failures. Agent-CI is a local CI runner. I tweaked the control pane and mounts to provide 0ms caching, insanely fast boots. When a step fails it pauses, provides the agent with the failure, and waits for the agent to fix and retry just that step. It uses the standard GH Actions image (via Docker), but emulates the control pane via a local HTTP server. You don't have to change any of your existing GH workflows. Tighter loops. Greener builds. Less babysitting. (Demo below.)

Lately I've been thinking about how agentic UIs fit between websites and chats. It seems Google's A2UI is already solve this problem and other attempts might exist.

I'm speaking in the @Future_Frontend meetup in Helsinki next week. I'll be yapping about my recent experiences with React Native, from building the Starmirror app for @hollyherndon and @matdryhurst.
