Matrix is an ambitious new ecosystem for open federated Instant Messaging and VoIP. The basics you need to know to get up and running are: * Everything in Matrix happens in a room. Rooms are distributed and do not exist on any single server. Rooms can be located using convenience aliases like #matrix:matrix.org or #test:localhost:8448. * Matrix user IDs look like @matthew:matrix.org (although in the future you will normally refer to yourself and others using a 3PID: email address, phone number, etc rather than manipulating Matrix user IDs) Synapse is currently in rapid development, but as of version 0.5 we believe it is sufficiently stable to be run as an internet-facing service for real usage!

tcpmssd was written by Ruslan Ermilov <ru@FreeBSD.org> based on work done by Patrick Bihan-Faou <patrick@mindstep.com>. tcpmssd is a divert(4) program that adjusts outgoing TCP data so that the requested segment size is not greater than the amount allowed by the interface MTU. This is necessary in many setups to avoid problems caused by routers that drop ICMP Datagram Too Big messages. Without these messages, the originating machine sends data, it passes the rogue router then hits a machine that has an MTU that is not big enough for the data. Because the IP Don't Fragment option is set, this machine sends an ICMP Datagram Too Big message back to the originator and drops the packet. The rogue router drops the ICMP message and the originator never gets to discover that it must reduce the fragment size or drop the IP Don't Fragment option from its outgoing data.

tcptraceroute is a traceroute implementation using TCP packets. The more traditional traceroute(8) sends out either UDP or ICMP ECHO packets with a TTL of one, and increments the TTL until the destination has been reached. By printing the gateways that generate ICMP time exceeded messages along the way, it is able to determine the path packets are taking to reach the destination. The problem is that with the widespread use of firewalls on the modern Internet, many of the packets that traceroute(8) sends out end up being filtered, making it impossible to completely trace the path to the destination. However, in many cases, these firewalls will permit inbound TCP packets to specific ports that hosts sitting behind the firewall are listening for connections on. By sending out TCP SYN packets instead of UDP or ICMP ECHO packets, tcptraceroute is able to bypass the most common firewall filters.

xmlrpc-epi is an implementation of the xmlrpc protocol in C. It provides an easy to use API for developers to serialize RPC requests to and from XML. It does *not* include a transport layer, such as HTTP. The API is primarily based upon proprietary code written for internal usage at Epinions.com, and was later modified to incorporate concepts from the xmlrpc protocol. It passed the xmlrpc validation test suite in December 2000. As of Sept. 27, 2001, experimental support for SOAP v 1.1 has been added to the library. This support is implemented transparently to the application such that a single API can be used for manipulation of values, yet both SOAP and XML-RPC can be read or written. Various iterations of this code have been/are running at Epinions.com and are sufficiently fast for the high traffic volume this site encounters, with several xmlrpc type requests generated for each user http request. No specific speed claims are made. Your mileage may vary.

The Zillion Project is a distributed computing project reminiscent of the good old Zilla.app of NeXTstep days. It is based on GNUstep, the most promising OPENSTEP replacement as of today. Jobs can be created from simple template projects and can be submitted with a single command to the Zillion Server which in turn will distribute the job amongst the registered clients. No other network resources than the distributed objects (DO) port of the server machine has to be available. The key features are as follows: * Rapid turn around cycles for job submission * Dynamic addition/removal of client nodes * Full OO-design * No need for shared network resources * Real-time capabilities * Lean and clean * Open and free LICENSE: BSD

This is a new release of the popular cleanfeed usenet spam filter written by Jeremy Nixon. I will continue releasing new versions until I get tired or somebody else will step forward. There is no real documentation, so if you never used cleanfeed please download the original package from and enjoy trying to understand what changed. If you already have an existing cleanfeed installation please double check your cleanfeed.local, because it may not be compatibile with this release. cleanfeed.conf does not exist anymore, the bad_cancel_paths config option is now read from a configuration file and most local_* functions changed their name. Please read the CHANGES file for details about these and other things. When in doubt, check the source code.

- Much from HTML 4.0 - that is relevant for printing - is supported (incidentally, the PostScript and PDF versions of the HTML 4.0 draft, were generated using html2ps). For example, all character entities (except &zwnj;, &zwj;, &lrm;, and &rlm;) are supported. - Many possibilities to control the appearance. Starting with this version, this is mostly done using configuration files. - Support for processing multiple documents, also automatically by recursively following links. - A table of contents can be generated, either from the links in a document, or automatically from document headings. - Configurable page headers/footers, that for example can contain document title, URL, page number, current heading, and date. - When converting the PostScript document to PDF - using some other program such as version 5.0 or later of Aladdin Ghostscript, or Adobe Acrobat Distiller - the original hyperlinks in the HTML documents will be retained in the PDF document. - Automatic hyphenation and text justification can be selected.

Net::Printer ============ Perl module for directly printing to a print server/printer without having to create a pipe to either lpr or lp. This essentially mimics what the BSD LPR program does by connecting directly to the line printer printer port (almost always 515), and transmitting the data and control information to the print server. Please note that this module only communicates with the BSD Line Printer Daemon Protocol as described in RFC-1179. It does not natively speak to remote print servers via SMB, Apple-Talk or Netware. Remote print services running lpsched, such as Sun Solaris or other Sys V-derived operating systems, will work so long as the print spoolers are set up to understand the BSD protocol. Most modern network-capable laser printers, such as those manufactured by HP and LexMark, also "speak" BSD.
