SQLiteManager is a Web-centric system to manage SQLite databases. You can maintain multiple databases, load or create databases with multiple tables, maintain field and index structures, dump database definitions with or without data, create CSV tables, create and load the database using DB definitions, load data with CSV data, query the database, and create Run Basic code for that query.
picoTK is a C GUI toolkit that requires only a minimum of memory resources. It is intended for embedded system use, especially for (but not limited to) the RTEMS realtime kernel. It is in no way comparable featurewise to a "real" full blown windows toolkit like Qt or nanoX; it rather provides simple drawing primitives like lines, filled rectangles, characters, and pixmaps. (But that is what many embedded applications might ask for.) It directly works on tailored "framebuffer" hardware. A Linux framebuffer emulator is supplied as part of the kit, making evaluation (and emulation!) possible without having a realtime OS and custom hardware.
miniIDE helps you run make, or similar build tools, and locates errors in source files that are reported by the compilers in an editor of your choice. Its design goal is a seamless and easy edit-build-debug cycle. Support for more editors can easily be added by editing a shell script.
