The PSXSDK is a free and open source software development kit that enables anyone with C programming knowledge to make programs and games for Sony's PlayStation console. Everything was either written from scratch or based on already available open source resources. It is thus free from any proprietary code and fully legal to use. The SDK is mostly geared towards a *nix environment, but is fully usable with emulation environments such as MSYS and Cygwin.
Hashrat is a hash-generation utility that supports the MD5, SHA1, SHA256, SHA512, Whirlpool, JH-224, JH-256, JH-384, and JH-512 hash functions, and also the HMAC versions of those functions. It can output in 'traditional' format (same as md5sum and shasum and the like), or its own format. Hashes can be output in octal, decimal, hexadecimal, uppercase hexadecimal, or base64. It supports directory recursion, hashing entire devices, and generating a hash for an entire directory. It has a 'CGI' mode that can be used as a Web page to lookup hashes.
Conseptizer is two things: 1. a closure(-mimic) / higher-order programming and dynamic typing library for the C programming language, 2. a very dynamic programming language that provides expressiveness through simplicity and offers powerful features that cannot be found in mainstream languages today. Each of these two aspects can be useful on their own, but the combination and tight integration in Conseptizer means: if at some point your runtime performance requirements are not fulfilled by the dynamic language, it is very easy to migrate parts of your program code to C.
The Collax Security Gateway is a Unified Threat Management (UTM) Solution for small- and medium-sized businesses. It includes an easy to configure stateful inspection firewall, email security features including anti-spam and anti-virus, Internet access control, Internet SSL interception, Internet networking optimization tools, Internet network fault tolerance, clientless VPN technology, and remote administration.
The Go Programming Language (Go) is an expressive, concise, clean, and efficient language with concurrency mechanisms that make it easy to write programs that get the most out of multicore and networked machines. Its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
