This package contains some primary tools for evaluating sums, averages, integrals, derivatives, histograms/distributions of 1-d numerical data, and eventually for plotting the results. The stand-alone programs (supporting the standard UNIX input and output pipelines) are intended for data processing from the command line. They are especially useful for straightforward analysis of number series where a complex analytical approach is not necessary.

Litecoin is a free open source peer-to-peer electronic cash system that is completely decentralized, without the need for a central server or trusted parties. Users hold the crypto keys to their own money and transact directly with each other, with the help of a P2P network to check for double-spending. Litecoin is a fork of Bitcoin.

Netrw is a simple (but powerful) tool for transporting data over the internet. Its main purpose is to simplify and speed up file transfers to hosts without an FTP server. It can also be used for uploading data to some other user. It is something like one-way netcat (nc) with some nice features concerning data transfers. Netrw can compute and check message digest (MD5, SHA-1, and some others) of all the data being transferred, it can also print information on progress and average speed. At the end it sums up the transfer.

check_multi is a multi purpose wrapper plugin which takes benefit of the Nagios/Icinga capability to display multiple lines of plugin output. It calls multiple child plugins and displays their output in the long_plugin_output. A summary is given in the standard plugin output. The child return code with the highest severity becomes the parent (check_multi) plugin return code.

utalk uses a protocol, based on UDP, which ensures a quick response even over links with high packet loss, allows editing of previously typed text, including scrollback, deletion and overstrike, and provides some additional features. It is not compatible with BSD talk program.

Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer.
