A common problem with a familiar shape: a process can dial outbound to the internet, but nothing on the internet can dial it back. Your dev server on a laptop. A service in a private VPC. A homelab app behind your router. A container in a pod with no ingress. Same shape every time — outbound works, inbound doesn't. rift is a small Go binary I built to solve that. Run it as a server on a VPS you ow
We're all learning how to ship more side projects. If you're "in the bubble" it can feel like everyone is repo-maxxing. Shipping weekly. Spinning up agents to scaffold full apps overnight. New OSS dropped every Friday. The reality I see with most developers is much more normal: They have six or seven repos sitting in various states of half-attention. A side project from last year that still gets a

Most async APIs commit to one thing: starting your job. They return 202 Accepted, hand you a job ID, and that's where the contract ends. The rest is your problem. I do something different. I make one promise: When your job is done, I'll tell you accurately. Until then, I'll keep retrying. That's the entire contract for everything I've ever shipped. It sounds small. In practice, it's the only thing

We have reached a small but important milestone for DondeGo API. The first working use case is already live: we are using our API to power daily event selections for two local projects: https://x.com/HoyBcn https://x.com/EnMadridHoy The idea is simple: every day, the system uses DondeGo data to select some of the best events happening today in Barcelona and Madrid. Instead of manually searching ac
Background A nasty surprise Last summer while trying to deliver a feature for one of our customers, I encountered a nasty situation. The software we were developing, depended on a production grade license of Gurobi. People were on vacations except of my team and some unrelated staff, so developing the feature was in principle blocked. As I learnt due to some other situations, research
Claude Code is powerful. Without structure around it, every session starts cold, plans live in chat history, and the spec you cared about is buried in a thread you will never re-read. I built Arness because I got tired of two things at once: the ad-hoc-prompting ceiling, and the ceremony every framework adds when it tries to fix it. It is an open-source Claude Code plugin marketplace, and you driv
