Formal Software Design Alloy is an open-source language and analyzer for software modeling. An Alloy model is a collection of constraints that describe a set of structures, e.g. all possible security configurations of a web application. Alloy’s tool, the Alloy Analyzer is a solver that takes the constraints of a model and finds structures that satisfy them.
📑 The Alloy Analyzer leverages a SAT solver, and this precludes Alloy from analyzing optimization problems....
Version Control Systems track changes to a folder and its contents in a series of snapshots. Each snapshot encapsulates the entire state of files/folders within a top-level directory.
Git’s interface is a leaky abstraction. While the interface is at times ugly, its underlying design and ideas are beautiful. A bottom-up explanation of Git therefore makes more sense.
Snapshots A blob corresponds to a file, and it’s just a bunch of bytes....
