Crossfire Extended Release is an extended version of Crossfire, a rogue-like 2D RPG, simulation, and graphical online chatroom. It features vast expanses and numerous cities, each with its own theme, deeply hidden worlds that very few ever venture to, flatworlds peeled off from the earth through hidden seas, and underground expanses. People can buy and build houses, towns, towers. There is a post office, banks, guilds. Boats one can own, castles one can rule over, forever, as a king. There is a weather simulation.
libdwarf reads and/or writes DWARF debugging information in Elf object files. dwarfdump uses libdwarf to read object files and print the DWARF content in a readable fashion. libdwarf implements the DWARF2 (and later) standard by providing function interfaces that abstract away many DWARF implementation details (the writer code only emits DWARF2 so far). The source also includes implementations of a few tree search (tsearch) algorithms (balanced, red-black, and binary).
Paranoid TelnetD is written in straight C with few dependencies. It is intended for use with embedded or legacy devices (like the hand-scanners used in warehouses) that communicate via telnet. It features: 'telnet only' user accounts, separate from the system authentication (so only the specified usernames/passwords can login via telnet, and only via telnet); user, IP address, and MAC address whitelisting/blacklisting; chrooting with 'bind mounts' to allow access to certain directories under the chroot jail; and 'honeypot mode' in which all authentication fails and all events are logged at syslog 'crit' level.
C Almost Generic Library (CAGL) is a set of C macros which generates typed arrays, lists (singly or doubly-linked), hash tables, and balanced binary trees, as well as many useful functions to manipulate them. The containers grow automatically, and their memory is managed by the library. The container data, or elements, may also be managed by the library, depending on the options specified by the programmer. The aim is to free C programmers from the drudgery of implementing common data structures and algorithms. CAGL also provides some safety by making the containers typed instead of void pointers. Although, at most, two macros are invoked to declare and define a container type, manipulation of the containers is done using functions generated by the macros. A simple naming convention is used to get around the limitation that C doesn't support function overloading.
