BillionMail is an open-source stack that combines a self-hosted mail server, webmail, newsletter, and email marketing into one Docker Compose deployment. Here is what it actually does, how to install it on a VPS, and the deliverability work it does not do for you.
GitHub open-sourced Spec Kit, a toolkit for spec-driven development that has over 110,000 stars. The idea is simple: instead of vibe coding and hoping AI guesses your intent, you write a clear spec first, then AI implements according to that spec.
You can learn SSH, host a personal site, and use mail, git, and chat without renting your own VPS, thanks to a community-run shared Linux server that hands out free accounts.
Oracle gives away more cloud infrastructure than most people realize, and the fine print is less restrictive than you might expect, as long as you know where to look.
One image in, one procedural 3D model running on the web out. That is the compact promise of img2threejs, an open source skill for coding agents.
The CEO of Y Combinator claims he ships code 810 times faster than he did in 2013 — not by typing faster, but by running 23 AI agents in parallel. The tool he uses is open source.
You are using AI agents to code, but have you tried Spec Driven? It helps AI make the right decisions instead of guessing the missing parts and coding away from your intent.
WebSocket is the only channel where both client and server can actively send messages at the same time. It is true full-duplex, not long-polling in disguise, and that makes it the backbone of chat, games, and collaboration tools.
WebRTC is the only protocol that lets video and audio travel directly between two browsers without passing through a server. That is why Google Meet, Discord, and Zoom on the web have low latency, and it is also why WebRTC is genuinely complex.
