    ssh chat.shazow.net▲171

    Hi HN, I wrote a custom SSH server in Go, give it a try. It uses your terminal user and SSH keys to authenticate implicitly. Instead of getting a shell, you get an IRC-style chatroom with everyone else. $ ssh chat.shazow.net If you're getting "Permission denied (publickey)", please use ssh-keygen to create a keypair. Instructions here: https://help.github.com/articles/generating-ssh-keys/ SSH is a really cool protocol; it's a lot like HTTP2. This is a demo of one thing you can do with it, but I plan to factor out the code into libraries that will let you build all…

    Greetings, This is a link to our learning guide to make your own MCP server in C/C++ (with no other dependencies). If you wanted to make one from scratch but needed some insight into dealing with MCP messages: the I/O flow, JSON parsing, and request dispatch, grab the teaching version tagged mcp/teaching/v1.0.0 in the repository. The JSON parsing in C would have been a hurdle, but then there's this amusing story: Eric: "Let's create a helloWorld MCP server in C." Gemini: "That will be somewhat difficult, there are easier ways." Eric: "Why is it difficult??" (the second…
