A Weird Imagination Unix sockets basic client/server example Posted Sun 05 July 2026 in Linux The problem # When writing confirm-module , my original design did the communication over a Unix socket. I spent a while trying to figure out how to implement a very simple client/server program that could send a query to a Unix socket and wait for a response as a shell script using socat and could not figure it out. And I couldn't find any example code showing how do to that. The solution # Using socat # # server

Introduction In the fast-changing world of AI development, one language is quietly stealing the spotlight in 2025: Mojo. Designed as a Python-compatible programming language with C++-level performance, Mojo promises to eliminate the trade-off between developer productivity and raw execution speed. With benchmarks showing up to 35,000× faster performance than Python, developers are flocking to try
