Groonga is a fast and accurate full text search engine based on an inverted index. Newly registered document instantly appears in search results, and updates are allowed without read locks. These characteristics result in superior performance for real-time applications. It is also a column-oriented database management system (DBMS). Compared with well-known row-oriented systems, such as MySQL and PostgreSQL, column-oriented systems are more suited for aggregate queries.
VGAVR is a program that provides an 18x19 text mode on 16MHz Atmel AVR microcontrollers using the 640x480@60Hz industry standard screen resolution. The rendered image is based on an ASCII text buffer and updated in real-time. The font is stored in program memory, so the SRAM usage is less than 400 bytes.
EXIP provides a C library for the parsing and serialization of Efficient XML Interchange (EXI) format streams. The focus is portability and efficiency for embedded systems development. The project was started at the EISLAB research group in the Department of Computer Science, Electrical and Space Engineering, Luleå University of Technology, and is part of research efforts to bring resource-constrained embedded devices, such as wireless sensor nodes, closer to the enterprise business processes taking place in processing, manufacturing, and communication industries.
xc is a simple and handy substitute for sudo. It parses the /etc/xc.conf file, containing a list of identifiers, accesses, and commands. If an identifier (given as an argument to xc) matches the corresponding access (i.e., user or group), the related command is executed. The user can only see the identifiers he can execute, and the real command attached to the identifier remains invisible to him.
YAGAC is a library that when linked to your C program, allows you to conveniently track or trash memory leaks within your application while it is still running. You can have multiple garbage collectors according the code part you are in. It tracks memory assigned by your code only, and does not monitor third part libraries. Tracking can be activated by updating a debug flag without restarting your application. It is intended for use with daemon-type programs.
Cock provides a digital version of a petcock. A petcock is a valve or faucet used to drain pressure, as from a boiler. Cock drains I/O pressure from the kernel. Without parameters, the output rate automatically adjusts; cock defers output when necessary in order to mitigate I/O spikes. Otherwise, a numeric parameter specifies megabytes per second.
