Micro Signage is a lightweight software suite that can be used as the basis for creating digital signage appliances, such as advertisement screens and full software systems. It is intended to be used to control the playback of media files and be managed over the network through a socket server, which is included.
lemontree provides a very fast Java class for the Walsh Hadamard transform (WHT) and O'Connor transform (OCT). You can regard the OCT as a black box which turns arbitrary numerical data into data with a Gaussian distribution. There are inverse transforms, also. It has many applications, such as Random Projections, Compressive Sensing, Neural Nets, and Genetic algorithms.
Date::Calc::XS is a Perl module that is the C/XS part which Date::Calc used to consist of. Date::Calc has become a (pure-Perl) wrapper which tries to load Date::Calc::XS, and failing that, loads Date::Calc::PP (a pure-Perl implementation which is now part of Date::Calc and used to be Date::Pcalc).
OpenBeacon is a open and generic design for an active wireless transceiver device hardware that operates in the 2.4GHz ISM band. The tag contains a unique serial number, but may have other information like acceleration measurement. The OpenBeacon tag is designed as a transceiver device, and therefore both transmits and receives radio waves. The intention of this project is to offer a wide range of use cases such as visitor or item tracking and wireless remote control with a free self-contained and low-cost RFID design. It enables wireless remote control application and ultra low power wireless meshing nodes.
The metric implemented in the Image::Density Perl Module estimates the density of data where there is data, and has a reasonable correlation with goodness as judged by humans. That is, if you let a human look at a set of images and judge quality, the density values for those images as calculated here tend to correlate well with the human judgement (densities that are too high or too low represent "bad'' images). It is intended for use on bitonal TIFF images, such as those from scanning paper documents.
