Free knights and merchants software for linux

The Merchant is a turn based RPG in which you explore the universe and trade to earn credits and experience.

The Merchant is implemented as a Web application.

The Merchant is still in the alpha stages, so the game is not complete but you may create an account and login.

Please play the game and help in the search for bugs.

KnightFight is a Java-based game in which you, the Bronze Knight, must take on the Black Knight in battle. Complete with goofy Pythonesque sound clips, it is intended as a parody of Street Fighter/Mortal Kombat-type games.

KnightFight is a fun game which I made in a period of three days. KnightFight project was intended as a joke, as evident from the goofy sound clips and lousy graphics, but I found it to be fun and addictive, so I released it. I may release a better-designed sequel in the future.

Xapian is an Open Source Probabilistic Information Retrieval library, released under the GPL. Xapian iss written in C++, with bindings to allow use from other languages (Perl, Java, Python, PHP, and TCL are currently supported; Guile and C# are being worked on).
Xapian is designed to be a highly adaptable toolkit to allow developers to easily add advanced indexing and search facilities to their own applications.
If youre after a packaged search engine for your website, you should take a look at Omega, which is an application we supply built upon Xapian. But unlike most other website search solutions, Xapians versatility allows you to extend Omega to meet your needs as they grow.
Main features:
- Free Software/Open Source - licensed under the GPL.
- Highly portable - runs on many Linux, MacOS X, many other Unix platforms, and Microsoft Windows.
- Written in C++. Perl bindings are available in the module Search::Xapian on CPAN. Java JNI bindings are included in the xapian-bindings module. We also support SWIG which can generate bindings for 13 languages. At present those for Python, PHP4, and TCL are working. Guile and C# are being worked on.
- Ranked probablistic search - important words get more weight than unimportant words, so the most relevant documents are more likely to come near the top of the results list.
- Relevance feedback - given one or more documents, Xapian can suggest the most relevant index terms to expand a query, suggest related documents, categorise documents, etc.
- Phrase and proximity searching - users can search for words occuring in an exact phrase or within a specified number of words, either in a specified order, or in any order.
- Full range of structured boolean search operators ("stock NOT market", etc). The results of the boolean search are ranked by the probablistic weights. Boolean filters can also be applied to restrict a probabilistic search.
- Supports stemming of search terms (e.g. a search for "football" would match documents which mention "footballs" or "footballer"). This helps to find relevant documents which might otherwise be missed. Stemmers are currently included for Danish, Dutch, English, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish.
- Supports database files > 2GB - essential for scaling to large document collections.
- Platform independent data formats - you can build a database on one machine and search it on another.
- Allows simultaneous update and searching. New documents become searchable right away.
As well as the library, we supply a number of small example programs, and a larger application - an indexing and CGI-based application called omega:
- The indexer supplied can index HTML, PHP, PDF, PostScript, and plain text. Adding support for indexing other formats is easy where conversion filters are available (e.g. Microsoft Word). This indexer works using the filing system, but we also provide a script to allow the htdig web crawler to be hooked in, allowing remote sites to be searched using Omega.
- You can also index data from any SQL or other RDBMS supported by the Perl DBI module. That includes MySQL, PostgreSQL, SQLite, Sybase, MS SQL, LDAP, and ODBC.
- CGI search front-end supplied with highly customisable appearance. This can also be customised to output results in XML or CSV, which is useful if you are dynamically generating pages (e.g. with PHP or mod_perl) and just want raw search results which you can process in your own page layout code.
Enhancements:
- This release adds support for spelling correction and synonym expansion.
- Some Btree tables are now optional, so opening a database is slightly quicker.
- The Xapian::NumberValueRangeProcessor class has been reworked to fix a design flaw.
- A few bugs have been fixed.
- Performance was improved in several cases.

get_iat and iat_cmp are two small programs to extract and to very basic analysis of packet inter arrival times (unfortunaly often wrongly called inter packet gaps) in a pcap network trace.

- get_iat just reads one pcap files an outputs the inter arrival time and the time
difference between this packet and the first one for all packets

- iat_cmp compares several pcap files and checks how much their inter arrival
times differ. This "compare" is done by sorting the inter arrival time
difference into buckets. Currently the buckets must be configured by hand
in the source code.

BEWARE: these programs have not been tested very exensively. So expect
crashes.

Installation:

Requires GNU make (gmake)
Edit the Makefile and change the path to your libpcap installation.

type :
# make
# make install

MiniUPnP Client and Daemon is an UPnP IGD client lightweight library and UPnP IGD daemon.
The UPnP protocol is supported by most home adsl/cable routers and Windows 2K/XP. The aim of the MiniUpnp project is to bring a free software solution to support the "Internet Gateway Device" part of the protocol.
The Linux SDK for UPnP devices (libupnp) seems too heavy for me. I want the simplest library possible, with the smallest footprint and no dependencies to other libraries such as XML parsers or HTTP implementations. All the code is pure ANSI C.
Compiled on a x86 PC, the miniupnp client library have less than 15KB code size. For instance, the upnpc sample program is around 20KB.
The project is divided in two main parts : the client library, enabling applications to access the services provided by an UPnP "Internet Gateway Device" present on the network, and the miniupnpd daemon, providing these services to your network from a linux or bsd box being the gateway. At the moment the miniupnpd is developped on OpenBSD 3.0+ with pf. You can see some of the work I have done to integrate with pf on this page.
As pf is also available under FreeBSD, guys at the pfSense project have ported miniupnpd to this system.
For some reasons, it may be not the good solution for you to use the code from the MiniUPnP project directly.
As the code is small and simple to understand, it is a good base to take inspiration for your own UPnP implementation. The KTorrent team UPnP plugin in C++ is a good example.
If you are wondering which home router is working with the miniupnp client, you can find the answer here. In fact, you are more likely to help me fill the list by sending me an email.
Usefulness of the miniUPnP client library
The usage of the miniUPnP client library is useful whenever an application needs to listen for incoming connections.
Examples : P2P applications, FTP clients for active mode, IRC (for DCC) or IM applications, network games, any server.
The typical usage of UPnP capabilities of a router is a file tranfert using MSN messenger. The MSN Messenger software uses the UPnP API of Windows XP to open port for incoming connection. To mimic the MS software, it is a good idea to use UPnP as well.
Enhancements:
- This release adds changes to accommodate the Linux 2.6.22 kernel.
