sphlib provides optimized implementations in both C and Java of cryptographic hash functions. The C code includes "small footprint" variants optimized for architectures with low L1 cache (e.g. WiFi routers running OpenWRT). The C code comes with a command-line tool that can serve as a drop-in replacement for md5sum, sha1sum, sha256sum, etc. for all implemented hash functions. The Java code is compatible with J2ME. There are implementations of fourteen "second-round" SHA-3 candidates, for all output lengths: BLAKE, Blue Midnight Wish, CubeHash, ECHO, Fugue, Grøstl, Hamsi, JH, Keccak, Luffa, Shabal, SHAvite-3, SIMD, and Skein. Some pre-SHA-3 hash functions (including MD4, MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512, RIPEMD-160, and others) are also implemented.
css-tools is a suite of tools for managing a large collection of CSS. It doesn’t contain an editor, but is intended to be used alongside an editor. Use css-tools to find out what needs doing, then use your editor to do it. At a later date, plugins for popular editors may be created so as to streamline the workflow. At present, css-tools contains one program, 'cssi', which parses and searches selectors.
ip2clue provides access to multiple databases (Maxmind, Software 77, Webhosting.info and ip2location) to retrieve country information associated with IP addresses. It has a daemon that supports lots of concurrent connections and a client binary. Some client examples are also provided in languages including PHP and C.
NSFFT is yet another FFT library for performing 1-dimensional fast Fourier transforms. It is a simple, small, and portable library, and it is efficient since it can utilize SIMD instruction sets in modern processors. It performs multiple transforms simultaneously, and thus it is especially suitable for digital signal processing.
Redshiftgui changes the color temperature of your monitor to better match that of your surrounding. This means that it sets a cooler color temperature during the daytime (due to natural lighting) and sets a warmer temperature at night (due to indoor lighting). Similar to f.lux, this is a GUI port of the redshift project.
catnip is a tiny network packet capturing tool that is not based on libpcap. When compiled and stripped, the binary is smaller than 20kiB. This makes it very suitable for embedded environments where a libpcap-based tool, typically 100kiB for just libpcap and 500kiB for tcpdump, would be simply too large. catnip is generally parameter compatible with tcpdump and what makes catnip stand out from other small packet capturing tools is that also supports BPF filtering.
StaticPython is a statically linked version of the Python 2.x (currently 2.7.1) and Stackless Python 2.x interpreters and their standard modules for 32-bit (i686, i386, x86) Linux, Mac OS X, and FreeBSD systems. It is distributed as single, statically linked 32-bit executable binaries, which contain the Python scripting engine, the interactive interpreter with command editing (readline), the Python debugger (pdb), most standard Python modules (including pure Python modules and C extensions), coroutine support using greenlet, and multithreading support. The binary contains both the pure Python modules and the C extensions, so no additional .py or .so files are needed to run it. It also works in a chroot environment. The binary uses uClibc, so it supports username lookups and DNS lookups as well (without NSS).
rofldns is DNS server which is a fork of loldns, itself a fork of djbdns. It inherits all the good stuff from loldns, which includes multiple listening IPs, running as a service rather than under daemontools, and some other useful patches, but in addition builds under automake and trivially makes an RPM.
