mysql-diff is a commandline database structure comparator. It compares the structure of two databases. It currently works with MySQL. A database can be specified as an SQL script or as an URL to a running database. So the tool can compare two scripts, two live databases, or a database and a script. The tool outputs SQL DDL script that can be used to convert one schema to another.
VRaptor3 is a fully-fledged Java Web framework focused on fast development and maintainable code. It intends to make RESTful application development easy. A resource corresponds to a business logic annotated with its path and HTTP method. It runs inside DI Containers (Spring or Pico out of the box) and, therefore, enables full integration with them. Also, using Hibernate is easier: its session is automatically injected by VRaptor, so you just have to use it. VRaptor3 is refactor-friendly, especially in its redirecting configuration. It is also nicely extensible.
Anchor automatically adds curly braces and semicolons to code written in various programming languages, saving typing and making programs easier to read. It lets you pretend to be coding in Python or Lua while actually writing standard C, Java, PHP, C++, .NET, C#, or D. A script may generate files in the target language and invoke the compiler. An example bash script integrates with TCC to make runnable "scripts" with the speed of C. The scripts are easily modified to target another compiler or interpreter.
