QMachine turnkey system
Documentation is a beautiful thing, but reading directions for installing software can be as painful as writing them. QMachine (QM), like many other projects, has a lot of individual pieces, and it can be difficult to understand how it all fits together just from reading the paper. So, even though the entire point of QM is that you should not install anything, this repository is for those who insist.
This repository contains the "blueprint" for a turnkey QM system that will use the Ruby version of the server-side components for simplicity. The Ruby version is deliberately simpler than the Node.js version because it was originally intended to be used as the "teaching version" of QM. It uses single-threaded, multi-process concurrency to handle HTTP requests, just like the Node.js version, and it uses the same calls to PostgreSQL for storage, too. The main difference is that the Ruby version uses synchronous (blocking) I/O, which makes the code shorter and easier to understand. There are other subtle differences, but those will gradually disappear in the future.
