SignPDF is a simple command line application to sign a PDF document. It can sign a PDF document with a valid certificate, encrypt/protect a PDF document, and timestamp a PDF document (optional feature). A JKS keystore with a cert signed by your desired CA is mandatory for use. The tsa_url of a timestamp server can be used to timestamp your documents. The signed PDF file is signed and protected with allowed restrictions to printing, content copying, and content copying for accessibility. By default, SignPDF creates a configuration file at ~/.signpdf, which can be edited for further use.
JEFF is an explanation facility framework written in Java. Explanation facilities date from the era of expert systems (ES), where they were used in order to provide an explanation about the inference process. The explanation they provided was supposed to clarify how the ES reached its conclusions or why it asked some question during fact acquisition. Nowadays, traditional ES development environments ("shells") have been replaced by rule engines (RE) and business rule management systems (BRMS), which seem to lack explanation facility functionality. JEFF was created in order to remedy this.
jnostromo provides drivers for the Razer Nostromo designed to be E-Sport legal. Profiles are unique user-defined keymappings and can be created for each game. A profile can have up to eight unique keymaps with mappings to switch between keymaps. jnostromo includes an easy-to-use configuration GUI to map keys from the nostromo to the keyboard and/or mouse. The configuration GUI can be hidden, and, at any time, the GUI can be displayed by clicking on the system tray icon. It's the goal of this project to make jnostromo the driver of choice for E-Sports and competitive gamers.
