HHVM (aka the HipHop Virtual Machine) is a virtual machine designed for executing programs written in Hack and PHP. It uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. To date, HHVM (and its predecessor HPHPc before it) has realized over a 9x increase in Web request throughput and over a 5x reduction in memory consumption for Facebook compared with the PHP 5.2 engine + APC. HHVM should be used together with a FastCGI-based Web server like Nginx or Apache.
f265 is a cross-platform HEVC/H.265 video encoder. The project initially targets high quality offline encoding, but it is not limited to this scope. It is designed from the ground up to maximize quality and performance in offline and real-time scenarios using recent hardware technology and interfaces such as the Intel® AVX2 instruction set.
LibreS3 is a robust open source implementation of the Amazon S3 service, supporting a subset of the S3 REST API. Standard S3 client libraries and tools (for example python-boto, s3cmd, DragonDisk, etc.) can be used to access it. LibreS3 uses Skylable SX as the storage backend, which automatically provides data deduplication and replication.
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.
