Using the resource module, Big is able to create a system where libraries written with it, calledresources, all have hookable, composable, reflectable and standardized APIs. With resource’s persistence features, developers are able to persist data to arbitrary databases using jugglingdb and simple CRUD methods.

gyp, short for "Generate Your Projects", is a build system written by Google that was specifically designed to build their Chromium web browser.gyp makes it easy to develop such a large project because the developers can create and test each piece individually by defining self-contained "targets". Then at Release-time, gyp makes it easy to stitch the "targets" together into a single statically linked executable. Ryan Dahl once called it "the module-system of C".

A little while back I bemoaned the state of server technology for secure websockets, as I was at the time putting in work on a Socket.io side project that needed to be HTTPS only. In due course that led a later post to outline a server setup that involved Stunnel and Varnish as the frontend proxies. It was a little Rube Goldberg, but worked nonetheless.
