uterus is a codec library for financial tick data with an emphasis on market data integrity and maintainability. It comes with a set of tools to convert (mux) and print (demux) data from some sources, and to perform standard tasks like selecting instruments, creating snapshots and candles from tick data, etc. Special care is taken to provide longevity and consistence. All timestamps are internally converted to coordinated time, and price and quantity quotes are converted to a monetary datatype which doesn't suffer from rounding errors. Most importantly, meta data is stored along with the payload data in an inseparable unit, to provide self-contained and self-documenting files or network streams.
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.
pg_repack is a PostgreSQL extension which lets you remove bloat from tables and indexes, and optionally restore the physical order of clustered indexes. Unlike CLUSTER and VACUUM FULL, it works online, without holding an exclusive lock on the processed tables during processing. pg_repack is efficient, with performance comparable to using CLUSTER directly.
Changing directories in bash can be tedious if you have long names or nested paths. Creating aliases or adding to the CDPATH can help, but can be improved on. Bashcd adds 6 new commands to make changing directories a bit easier. This commands use find, the locate database, the mdfind database, or other contextual information to make it easier to change to other directories.
HtmlCleaner is an HTML parser. HTML found on the Web is usually dirty, ill-formed, and unsuitable for further processing. For any serious consumption of such documents, it is necessary to first clean up the mess and bring order to the tags, attributes, and ordinary text. For a given HTML document, HtmlCleaner reorders individual elements and produces well-formed XML. By default, it follows rules similar to those which most Web browsers use to create a Document Object Model. However, the user may provide custom tag and rule sets for tag filtering and balancing.
Plgen (Playlist Generator) is a tool that sorts files for MP3 players in a user defined order. Cheap MP3 players often come with no playlist capabilities. In addition these players often make use of the FAT16/32 file system, leading to confusion when the playing order is not alphabetical on the device even though it is shown as alphabetical in the file explorer.
M-Pin Strong Authentication System enables true two-factor authentication for Web sites and applications, based on the open source M-Pin Authentication Server and M-Pin Managed Service. The M-Pin Managed Service is a highly available, fault tolerant software as a service that issues cryptographic secrets to M-Pin Authentication Servers and Clients. The M-Pin Authentication Server uses just one leak-proof cryptographic key, and can't reveal any information about your users such as identity or login details, even if the key is compromised. The M-Pin Client is an HTML5 browser, so developers can easily integrate M-Pin into their Web sites and applications, enabling frictionless two-factor authentication and removing all username / password vulnerabilities.
