CPC (Continuation Passing C) is a programming language designed for writing concurrent systems. The CPC programmer manipulates very lightweight threads, choosing whether they should be cooperatively or preemptively scheduled at any given point; the CPC program is then processed by the CPC translator, which produces highly efficient event-loop code. This approach gives the best both worlds: the relative convenience of programming with threads, and the low memory usage of event-loop code. The semantics of CPC is defined as a source-to-source translation from CPC into plain C using a technique known as conversion into Continuation Passing Style. The current implementation of CPC has been used to write Hekate, a BitTorrent seeder designed to handle millions of simultaneous torrents and tens of thousands of simultaneously connected peers.
NanoHttpd is a lightweight HTTP server designed for embedding in other applications. It's only one Java file, in two "flavors", one strictly Java 1.1 compatible, and one at "current" standards. It supports GET, POST, PUT, HEAD and DELETE requests, and supports file uploading with very small memory overhead. Temp file usage and the threading model are easily customized.
sdparm has a command line interface for getting and setting SCSI mode page fields. Fields can be referred to by an acronym or a numerical address. It has support for various SCSI transport and vendor-specific mode pages. It also decodes Vital Product Data (VPD) pages and can send some simple SCSI commands. sdparm was originally written for Linux with ports to FreeBSD, Solaris, Tru64, and Windows.
C-Dogs SDL is a port of the old DOS arcade game C-Dogs to modern operating systems. C-Dogs is an arcade shoot-em-up which lets players work alone or co-operativly during missions, and against each other in the "dogfight" deathmatch mode. The original DOS version of C-Dogs came with several built in missions and dogfight maps, and this version is no exception. The author of the DOS version of C-Dogs was Ronny Wester.
Unifdef is useful for removing #ifdef'ed lines from a file while otherwise leaving the file alone. You specify which symbols are defined or undefined with -D and -U flags, and unifdef removes the corresponding ifdefs, and the enclosed code if appropriate. It's especially useful for removing those "#ifdef BROKEN" and "#ifdef PRIVATE" clauses from code before you release it. Unifdef acts on #if, #ifdef, #ifndef, #elif, #else, and #endif lines, and it knows only enough about C and C++ to know when one of these is inactive because it is inside a comment or a single or double quote.
basE91 is an advanced method for encoding binary data as ASCII characters. It is similar to UUencode or base64, but is more efficient. The overhead produced by basE91 depends on the input data. It amounts at most to 23% (versus 33% for base64) and can range down to 14%, which typically occurs on 0-byte blocks. This makes basE91 very useful for transferring larger files over binary unsafe connections like e-mail or terminal lines.
Repocafe helps users and admins manage subversion repositories. Admins can easily set up svn hosting. Users can create repositories and manage repo/path access rights using the self-service Web application. Authentication is LDAP-based. Using multiple LDAPs is supported. It is easy to facilitate use of large existing groups.
