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, GrÝstl, 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.
srmio is a library to access the most important functions of a Schoberer Radmesstechnik (SRM) PowerControl V, VI, and 7. You can download the data, mark it deleted, sync the time, and set the recording interval. To be as compatible as possible, it reads (SRM5/SRM6/SRM7) and writes (SRM7) files in the same format that srmwin uses.
stdnoj is a cross-platform C++ class library that includes classes for using portable strings, databases, SMTP, POP, NNTP, arrays, files, directories, logging, email, and sockets. While templates are used, no reliance upon STL or other (traditionally error-prone) technologies has been used, which increases portability between compilers.
steelpoll is a Web polling application which allows you to quickly and easily create and manage polls by just editing plain Tcl files. A single poll can be created by editing the variables in a single file. You can optionally control votes by checking the user's IP address. A parsed vote log can be viewed. It doesn't require any SQL database backend because it stores the results in easily parsed plain text files. It doesn't use graphics to display poll results, which is great for text-based Web browsers.
