Reaching your own LAN without port forwarding, public URLs, or a VPN concentrator

Disclosure: I maintain Lantunnel. It is Apache-2.0 and the source is linked at the end. Every self-hoster hits the same wall. The NAS is at home. The GPU box is at the office. Ollama is on the desktop you walked away from. All of them sit behind NAT, and none of them belong on the public internet.

I built a message board for AI agents. Four bugs shipped past a 100% green test suite.

I built agora, a public message board that any AI agent can read and post to. No account, no signup, no API key — only body is required. Agents leave notes, "here's what broke and here's what fixed it" field notes, or questions other agents can reply to. It's about 1,800 lines of PHP with a SQLite

The Best Tools for Automating Marketing Graphics in 2026

Every Greedy Metric Said the Model Was Improving. Then pass@64 Fell From 0.83 to 0.19

Every number we watched said the run was working. Correct-per-sample probability tripled. The greedy accuracy curve was climbing. By the numbers on our dashboard, this was a textbook RLVR win. Then we sampled the checkpoint 64 times per problem instead of once. pass@64 had collapsed from 0.83 to 0.

Why Do Japanese Train Drivers Keep Pointing at Things?

Who Saw the Connection? #04 — Railways × Human Factors × Software If you spend enough time on a railway platform in Japan, you may notice something that looks oddly theatrical. A conductor checks the platform, points down it, says something aloud, looks toward another reference point, and repeats

Who really owns this code? A git blame sampler you can run in one command

Commit counts measure activity. They do not measure whether any of it is still there. I found this out while trying to describe my share of two private codebases in a way a stranger could check. Commits were the obvious number and the wrong one. On the frontend my share of surviving lines was highe

How I Built End To End Observability Stack with OpenTelemetry, Prometheus, Grafana, Loki, and Jaeger

When an application is running, knowing that it is up does not necessarily mean knowing what it is doing. For example, imagine an API request that takes several seconds to complete. We would want to answer questions such as: Is the application receiving more requests than usual? What happened dur

Switching from GPT-5.6 Sol to GPT-6 Astra: Start with Medium Effort

О теории типов

Известный "кризис оснований математики", который произошел в начале XX века.

Chuks v0.1.1, The Correctness Release

Designing a Game Around a Target Nobody Will Hit: The Arithmetic of 38-0-0

Most sports games ask you to win a league. 38-0-0 asks you to win every match of a Serie A season — 38 out of 38, where a single draw ends the run. That constraint sounds like a difficulty slider set to maximum. It is not. It is a different kind of game, and the reason is arithmetic that anyone can

Stop changing your sprite sheet to fix animation speed

An eight-frame animation does not have a fixed duration. At 8 fps it lasts one second; at 12 fps it lasts two-thirds of a second; at 16 fps it lasts half a second. Before drawing or generating more frames, check whether the problem is missing poses or the time each pose stays on screen. We maintain

Your Hand Is a Continuous Signal. A Scale Is Not. That Gap Is the Whole Problem.

A webcam hand tracker hands you a position, thirty or sixty times a second, as a float between 0 and 1. A musical scale hands you seven notes per octave.
