Nautilus secure phone is a program that allows two parties to hold a secure voice conversation. Released in May of 1995, it ran on ordinary phone lines using a pair of modems (one at each end). It was meant as an answer to NSA's attempts to force "key escrow" on encrypted communication. Later versions of the program could also use TCP, i.e. the Internet. After the original developers abandoned the project, it was taken over by German maintainers. Actual development focuses on porting to the ARM platform and portability.
Fityk is nonlinear curve-fitting and data analysis software. It allows data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. It knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. It also enables background subtracting, data calibration, and task automation with a simple script language. It is mainly used to analyze powder diffraction patterns, chromatography, photoluminescence, infrared, and Raman spectroscopy, but it can be used to fit analytical functions to any kind of data.
Freehelpdesk is feature-rich help desk system designed from the ground up to meet the demands of help desk staff and their users. It is a Web-based system that can accept new calls from your users directly into the system. Calls can be tracked and searched to enable faster response times.
dnscrypt-proxy acts as a DNS proxy between a regular client, like a DNS cache or an operating system stub resolver, and a DNSCrypt-aware resolver, like OpenDNS. The DNSCrypt protocol focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network (which is often the weakest link in the chain) against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.
BitWrk is creating a marketplace where participants can buy or sell computing power like stocks in a stock exchange, using Bitcoin as currency. The client software can be integrated with existing, compute-intensive applications (e.g. rendering software), creating a big boost by harnessing the combined computing power of the BitWrk network. Sellers earn money by putting their hardware to work, offering an alternative to Bitcoin mining.
Aspose.OCR for .NET is a character recognition component built to allow developers to add OCR functionality in their ASP .NET Web applications, Web services, and applications. It provides a simple set of classes for controlling character recognition tasks and supports BMP and TIFF.
