Darkwaar20 commence par du bruit. Un plateau de 7×9 ne contient au départ ni terrain, ni chemin, ni objectif, ni structure visuelle significative. Chacune de ses 63 cases contient quatre canaux d’entiers générés à partir d’une graine. Cinq transformations plus tard, ces mêmes entiers décrivent un monde composé de sol, de vide, d’énergie, d’un noyau et d’une sortie. La transformation n’est pas automatique. Avant chaque passage, le joueur choisit comment le bruit doit se stabiliser. La génér...

This is a submission for the Sanity Challenge, Path Two: Vibe-Code Something Strange . What I Built Decision Lab is a small workspace for choices that have no obvious winner. Instead of asking one question and returning a confident answer, it lets people describe the options, name the criteria that matter, assign scores, and then move the importance sliders to see whether their conclusion survives a change in priorities. The demo compares two project ideas: AI Study Planner...

A physical piggy bank has one frustrating property: you can add cash easily, but you cannot see the total without counting its contents. PennyTap is an Android app that records each deposit so the total and progress toward a savings goal remain visible. The interface is deliberately small: choose a cash denomination or enter an amount, set a goal, and review a history of deposits. The interesting engineering work is in keeping those numbers honest. Here are three decisions from the PennyTap c...

TL;DR The hidden trail : Cursor, Claude Code, and GitHub Copilot store credentials across config files, env variables, logs, shell history, and temp files that repository and CI scanners never inspect. The evidence : GitGuardian's State of Secrets Sprawl 2026 found 24,008 unique secrets in public MCP configuration files, 2,117 of them valid, plus a 3.2% leak rate in Claude Code-assisted commits. The fix : GitGuardian Developer Endpoint Protection discovers this trail fleet-wide w...

Short answer: for a marketplace workspace that must show who is online, start with ephemeral presence plus a bounded reconnect backfill, and validate every event constant against the provider's supported type list before serving traffic. A misspelled event name produces the most misleading symptom in this system: the publish appears to happen, no subscriber receives it, and no error explains the gap. The least complex fix is a startup assertion over one authoritative constants module. Do that...

Your calendar already knows when you worked. A timesheet is those events, for one week or month, with hours added up. Steps Export the week or month to a sheet (start, end, title, hours). Round each event the way you bill: up to 15 minutes, for example. Group by day or week with a pivot table. Remove events you declined or never answered. Google Calendar hours report by client If you track client work in Google Calendar, you can bill from it. You need a ...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built I built ReplyBuddy, a simple AI-powered tool that helps you write better replies to messages. The idea came from a small but very common problem. Sometimes you know what you want to say, but you are not sure how to say it. You might want to sound friendly without being too casual, professional without sounding robotic, or simply want a short and natural reply. I built ReplyBuddy...

This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend What I Built OutingFit Mumbai helps you decide what to wear and what to carry for an outing in Mumbai, based on the actual forecast for when you'll be out. It works by voice or text in English, Hindi or Marathi. I have built this application for my lady friends who get confused that should they wear dress, jacket, carry a raincoat or sunglasses. Demo OutingFit Code ...

The Error You run git pull or git merge and see: fatal: refusing to merge unrelated histories Why It Happens Git refuses to merge branches that do not share a common ancestor commit. This typically happens when you created a local repo with git init , created a remote repository on GitHub with a default README.md or .gitignore , and then tried to connect them. The Quick Fix (One-Liner) Force Git to merge the two independent project hi...

There's a specific image problem that most tools have no good answer for: the words are already part of the picture, and the original design file is gone. A cafe renames itself, but the sign photo is already printed on the menu. An event moves a week later, but the poster only exists as a JPG. A price goes up and the shelf label is a flat photo from two years ago. In each case, re-shooting costs more than the change is worth. Photoshop is the obvious answer and usually the wrong one. The...

Originally published at cchinchilla.dev . Part 5 of From code to weights, a 12-part series on ML fundamentals for engineers. Part 4 ended on one stage. A decoder is a stack of blocks, twelve in GPT-2 small, and attention is one of two stages in each. This post reads a whole block the way you'd read a pipeline: what flows in, what each stage writes, and where the parameters and the cost end up. They don't end up in the same place. I read Block in nanoGPT's model.py with the shape...

AI and automation are reshaping work — but technology alone doesn't transform organizations. The future belongs to leaders who build innovation capacity.

A timeout is not a failure. How to stop an AI agent re-running finished work: an unknown state, a gate in the executor, and an open-source demo.

I did not quit Firefox in one day. Brave was my backup until it became my default. This is how Mozilla slowly lost me.

Why I still choose boring VPS hosting over AWS in 2026, how I keep infrastructure simple, and why fewer moving parts help me ship faster.

AI costs aren't the real problem. Visibility is. Why cheaper tokens won't save you, and how to govern AI by outcomes, not licenses.
