The Packet Design Embedded Library (PDEL) is a C library containing an
assorted collection of code useful for developing embedded applications:
- C data structure run-time introspection library
- Threaded HTTP client/server library with SSL and XML-RPC support
- PPP library using netgraph(4) with PPTP and L2TP servers
- Application configuration framework
- Heap memory accounting and sanity checking
- Generic template processing library
- Routines to configure networking interfaces, ARP and routing tables
- Logging library
- Generic TCP server
- Generic hash table implementation
- Generic balanced tree implementation
- Miscellaneous FILE * enhancements
- Base-64 encoding/decoding
- Events and actions with automated locking
- Generalized per-thread variables
- Message ports
- Digital signature creation/verification
- Filesystem mounting/unmounting
- String quoting/parsing
Consistent hashing is a scheme that provides hash table functionality
in a way that the addition or removal of one slot does not
significantly change the mapping of keys to slots. In contrast, in
most traditional hash tables, a change in the number of array slots
causes nearly all keys to be remapped.
Consistent hashing was introduced in 1997 as a way of distributing
requests among a changing population of web servers. More recently, it
and similar techniques have been employed in distributed hash tables.
This port contains the userland implementation of Grand Central Dispatch
technology.
The central insight of GCD is shifting the responsibility for managing threads
and their execution from applications to the operating system. As a result,
programmers can write less code to deal with concurrent operations in their
applications, and the system can perform more efficiently on single-processor
machines, large multiprocessor servers, and everything in between. Without a
pervasive approach such as GCD, even the best-written application cannot
deliver the best possible performance, because it doesn'tt have full insight
into everything else happening in the system.
From the README:
Twisted is an event-based framework for Internet applications. It includes
a web server, a telnet server, a chat server, a news server, a generic
client and server for remote object access, and APIs for creating new
protocols and services. Twisted supports integration of the Tk, GTK+, Qt or
wxPython event loop with its main event loop. The Win32 event loop is also
supported, as is basic support for running servers on top of Jython.
Twisted is based on an unconventional and somewhat Twisted design philosophy.

Jftpgw is an FTP proxy/gateway that uses the FTP protocol (unlike those FTP
proxies that fetch an FTP file but work as an http proxy). You can use it to
make servers behind a firewall/NAT server (masquerading server) accessible
or to allow users behind such solutions to transfer files to and from the
outside of the LAN.
Jftpgw is highly configurable and can be run as a stand-alone daemon or
under control of inetd. A wide range of options can be spedified per client,
server or user. Other features are: support for a transparent proxy mode,
forwarding, file caching, detailed logging, port ranges and session limits.
oftpd is designed to be as secure as an anonymous FTP server can possibly be.
It runs as non-root for most of the time, and uses the Unix chroot() command to
hide most of the systems directories from external users - they cannot change
into them even if the server is totally compromised! It contains its own
directory change code, so that it can run efficiently as a threaded server, and
its own directory listing code (most FTP servers execute the system "ls"
command to list files).
Pure-FTPd is a fast, production-quality, standard-conformant FTP server, based
upon Troll-FTPd.
Unlike other popular FTP servers, it's designed to be secure in default
configuration, has no known buffer overflow, it is really trivial to set up and
it is especially designed for modern kernels.
Features include PAM support, IPv6, chroot()ed home directories, virtual
domains, built-in 'ls', anti-warez system, configurable ports for passive
downloads, FXP protocol, bandwidth throttling, ratios, LDAP, customizable SQL,
fortune files, Apache-like log files, fast standalone mode, text / HTML / XML
real-time status report, virtual users, virtual quotas, privilege separation and
more.

Riece is an IRC client for Emacs. It provides the following features:
- Several IRC servers may be used at the same time.
- Essential features can be built upon the extension framework (called
"add-on") capable of dependency tracking.
- Installation is easy. Riece doesn't depend on other packages.
- Setup is easy. Automatically save/restore the configuration.
- Riece uses separate windows to display users, channels, and
dialogues. The user can select the window layout.
- Step-by-step instructions (currently written in Japanese) are included.
- Mostly compliant with RFC 2812.
