C++ MudBase project is a small embryo of basic mudrelated functions that could be extended into a fullfeatured game. It contains a basic map system with editor, a character definition, and an easy to extend command parser. The source code is released under the GNU GPL license.

The Map

The map consists of different areas. Each area consists of interlinked chunks with an absolute size which is the same for all chunks in the area. Chunks can be linked in all directions as well as up and down. Different areas can be linked together using portals. The C++ MudBase contains a basic map editor.

The Character

The character class contains only the information needed to support the map and editor function. Each character must also select a Race, which will determine in-game attributes such as sight.

The command parser

Each command is a C++ class which extends the Command class. When all necessary methods are implemented and the new class added to the global commands list, all parsing and help text generation is done automatically.

The Database Support

The C++ MudBase supports sqlite through the sqlitewrapped C++ wrapper. That wrapper also exists for MySQL and ODBC. The sqlite and MySQL wrappers are cross-platform. Database access classes are generated by sql2class, a sql to C++ code generator.

Networking

All socket communication is implemented using the C++ sockets library, which also is cross-platform.

B::Bytecode is Perl compilers bytecode backend.

SYNOPSIS

perl -MO=Bytecode[,-H][,-oscript.plc] script.pl

Compiles a Perl script into a bytecode format that could be loaded later by the ByteLoader module and executed as a regular Perl script.

EXAMPLE

$ perl -MO=Bytecode,-H,-ohi -e print "hi!n"
$ perl hi
hi!

OPTIONS

-b

Save all the BEGIN blocks. Normally only BEGIN blocks that require other files (ex. use Foo;) are saved.

-H

prepend a use ByteLoader VERSION; line to the produced bytecode.

-k

keep the syntax tree - it is stripped by default.

-ooutfile

put the bytecode in instead of dumping it to STDOUT.

-s

scan the script for # line .. directives and for < goto LABEL > expressions. When gotos are found keep the syntax tree.

ProSum is a terminal based program that protects your files, sys_call_table and IDT like tripwire way (All in user space, without kernel modules).
In addition, database with files etc. could be encrypted with Blowfish algorythm and files that are protected could be store at any secure/bastion host to later replace them. You can disable sys_call_table and IDT support for Non-Linux systems. ProSum could be run on any UNIX system, at least with file protect mode (without IDT and sys_call_table support). ProSum was designed for if you run it on Linux x86 platform, kernel havent LKM support or have any type of protection against load and unload LKM, for many protection. Anyway this is not neccesary, but is recommended.
Main features:
- - IDT, Kernel Symbols and Syscall hacking protection throught /dev/kmem for Linux x86 (developing protection for Linux sparc).
- File protection in a Tripwire way on any UNIX POSIX compliant.
- Database encryption with Blowfish algorythm on any UNIX.
- Recover files which are protected from a bastion/secure host.
- Syscall hacking by method described on http://www.big.net.au/~silvio/stealth-syscall.txt protection.
Enhancements:
- INSTALL.es translated to english on INSTALL.en Support for extended flags on Linux.
- To run program you need password that you define in config_prosum.h
- User could be specify random seed for ivec to encrypt BBDD.
- Now encryption support works, tested on Linux, *BSD and Solaris.
- Fixed removing absolute path on snd_tcp_serv.c
- Now you can compile program without gettext support with --disable-nls
- OpenSSL API have been removed for encryption support because there are many problems with it and non-Linux systems, and API of GnuPG 1.0.7 have been added.
- Fixed malfunctions with GNU make.
- Now you can protect files from different hosts in an unique bastion host.
- Now you can protect files that starting by a point (.).
- Added protection against kernel symbols hacking on Linux x86.
- Fixed BUG on big endianess architecture machines with htons() and md5.
- Fixed BUG with getopt().
- Fixed BUG when program comprobes if file were symbolic link.
- Internal code reestructuration.
- Fixed return type of signal() for portability.
- Changed way for handling errors.
- Added lock file for prevent that more than one ProSum can be running at the same me.

Date Calculator is a date calculator application written in pyqt. You can add or subtract days to a date, or calculate the number of days between two dates.

You can also choose to run your calculations using only working days and/or calculate inclusive of the start/end dates. There is a comprehensive gui for setting holiday dates.

Holidays can be fixed annual dates, variable dates, such as "the 1st Monday in June" or "the closest Monday to 22 February". This utility could be useful for people who need to be able to calculate time critical deadlines, such as lawyers.

Date Calculator application is also available as a superkaramba theme. You can download both from the download link.

CuteFlow is a webbased document circulation tool. Users are able to define "documents" which are send step by step to every station/user in a list.

CuteFlow is an electronical way for doing (i.e. internal) document circulations.

A document can be assembled from input fields that could be filled by the receiver of the document.

So after a completed circulation you will have a completely filled document. Also Attachments to the document are possible (i.e. for illustration material).

Carnarvon is a software archaeology analysis tool. A lot of software is developed using version control tools from which it is possible to extract even when a single line of code was most recently edited.
Collecting this kind of data and analyzing it statistically could show information in terms of software aging, and indicators of maintainability could be obtained from different perspectives, systems area and development area, for example.
Enhancements:
- This release adds newly-created man pages, Linux (.rpm) and MacOS X (.pkg) installation distribution packages, and samples of graphs obtained from the GAIM subversion repository analysis (downloadable separately from the project site front page).

Postfilter is a perl filter for Internet Net News (innd) which checks all messages sent by local users searching for spam and invalid contents.
Although Postfilter is designed for large sites that need a complex tool, Postfilter could by used also by local or private servers.
Main features:
- A powerful banlist: rules can be based on every header and each article could be rejected, silently discarded, tracked throught syslog or saved for further inspection
- A content-based filter. A score could be assigned to every regex; when the body matches an expression, the assigned score is added to the total. If an article exceeds the maximum allowed score, its rejected by the script.
- A fine regulation of clients activity. Postfilter allows to set a max number of articles, bytes, groups, followups, crossposts, hierarchies and errors per time. A second shorter interval is also setable to avoid floods. All these rules can be applied to IP, domain (level n-1) or userid.
- Several built-in syntax checks that scans the headers searching for errors commonly made by spammers.
- A white list that allows to exclude from the check every article that matches a regular expression or every article that includes a predefined header.
Postfilter is released under the terms of BSD License.
