Blueprint: Declare Your Dev Environment Once, Apply It Anywhere

Your README has a Setup section. It has eight steps, two of them are out of date, and step 5 assumes you're on macOS. A new dev joins the team and spends their first afternoon figuring out which version of Node you're actually on. You can do better than that. One .bp file in the repo and one command is all it takes. What Blueprint Does Blueprint is a declarative rule engine for dev...

I don't want AI to rewrite code I already trust

I've built a lot of projects in Python, Go, and Rust.Because of that, I keep reusing the same kinds of code over and over: chunked pandas CSV processing health check endpoints retry wrappers validation helpers rate limiting small bits of glue code that are easy to forget and annoying to rewrite The problem is not that I don't have this code. The problem is that it is spread across a bunch of ...

Your Phone Connects to Fake Cell Towers Daily — Here's How I Detect Them

Your phone will connect to the strongest tower it hears. It does not ask for ID first. It assumes trust, and that assumption is the entire problem. I first noticed this in 2019 outside a security conference in Las Vegas. My test Android dropped from LTE to 2G for 47 seconds, then returned to normal. No user notification. The baseband logs showed a cipher downgrade to A5/0, a location area code th...

Why developers end up fighting their commerce platform

It isn’t likely that most developers begin developing an e-commerce solution with the thought of “this commerce platform will be my biggest enemy”. However, it eventually becomes apparent to developers that they spend most of their time working around their commerce platform. It isn’t usually because of the tools or lack of expertise. Opinionated frameworks versus reality The major...

Claude Desktop com duas contas no macOS: como rodar pessoal e empresa lado a lado

TL;DR: Claude Desktop não suporta múltiplas contas nativamente. A solução é copiar o .app, modificar o wrapper de lançamento para apontar para um user-data-dir diferente, e re-assinar ad-hoc. O CLI continua único em ~/.claude/. Dois gotchas críticos: nunca altere CFBundleName no Info.plist (o Electron crasha) e remova CFBundleIconName se quiser ícone customizado (o macOS prioriza o Asset Catalog ...

Mnemara — a runtime for the Claude Agent SDK that uses the role doc as a self-monitoring layer

Sharing a project I've been building on top of the Claude Agent SDK in case it's useful to anyone here. Curious about feedback from people running into the same failure modes. The thing I actually wanted to figure out was: where do you put rules that keep an agent from looping, drifting, or sycophantically reversing? The SDK gives you tool definitions, can_use_tool, system_prompt, etc. — but once...
