2e is an experimental language designed to be as simple as possible, but still allow for all the standard programming functions (expression evaluation, flow control, functions, variables, and arrays, etc). The language flow control is handled via a C style conditional operator (expr ? expr2 : expr3) for if/else processing, and a variant iterative conditional (expr ?? expr2 : expr3) for looping. Parentheses are used for grouping throughout, and both built-in and user-defined functions are supported. The language itself is referred to as 2e, while the interpreter is called ee. The interpreter is designed to be used stand-alone, and it can also be easily embedded within another application.
SNeBU (Simple Network Backup Utility) is a backup system that supports incremental snapshot-style backups to disk-based storage. The project has been rewritten in C, and stores its backup catalog in an SQLite database. It features file level deduplication (including across multiple clients), compressed storage, incremental-forever snapshot style backups, simple setup, and utilizes standard TAR format. The client side consists of a simple shell script, which can be easily installed and adapted as needed. The server side is a single binary plus a config file, which can sit on a remote server and be accessed over SSH.
