Marauder-ah project is a 2d space fighting game.
Marauder-ah is a set of improvements over "marauder", originally written by Shawn Hargreaves in 1994.
You control a spaceship with a basic weapon, and your purpose is to kill as many people as you can.
Earning money (using piracy or trade) enables you to upgrade your ship and buy deadly weapons.
Game Rules:
Many years from now, in a distant corner of the galaxy, blah blah.
Ok. The rules are simple. Earn as much money as you can, and dont get shot.
When you start the game, you will see a little spaceship in the middle of the screen. That is you. Use the left and right arrow keys to turn, and the up arrow to fire your thrusters. Once you start moving it is not easy to stop. You will eventually coast to a halt, but if you are in a hurry you will have to turn round and fire your thrusters in the opposite direction.
If you fly around a bit, you will probably come across a planet or another hip (HINT: you can see all the planets and ships on the radar display at the top right of the screen).
There are two things to remember about planets. One is that if you fly into
them you get hurt. The other is that if you fly up close to one and then
press ENTER, you go to the shipyard.

- Changed weapon price

filepp is a generic file preprocessor. It is designed to allow the functionality provided by the C preprocessor to be used with any file type. This project supports the following keywords, all of which have their usual C preprocessor meanings and usage:
- #include
- #define
- #if
- #elif
- #ifdef
- #ifndef
- #else
- #endif
- #undef
- #error
- #warning
However, filepp is much more than a rewrite of the C preprocessor, it features the following enhancements:
- An extended #if keyword which includes string and regular expression parsing.
- It works with all character sets including international characters, not just ASCII characters.
- The prefix to the keyword (normally #) and the line continuation character (normally ) can be set to any character, string or regular expression.
- Keywords can be added, removed or modified.
- Macro expansion can work on whole or part words (the C preprocessors macro expansion only works on whole words).
- Macros can have multiple arguments.
- Filepp has a debugging mode to help when things go wrong.
- Environment variables can be automatically defined as macros.
- Blank lines originating from include files can be suppressed.
- Filepp can be customised on the fly using the #pragma keyword which allows any of filepps internal functions to be called.
- Modules can be written (in Perl) to modify or extend the behaviour of filepp.
These are just some of the enhancements filepp has over the normal C preprocessor. Its main advantage is the ability to write modules to extend and modify its behaviour. Filepp is written in Perl and allows anyone who knows how to program in Perl to easily write modules. Filepp comes with a set of modules which do the following:
- for module: Implements the #for keyword. The allows loops to be generated, the behaviour is similar to Perl and C loops.
- foreach module: Implements the #foreach keyword. The allows loops to be generated for a list of strings, the behaviour is similar to Perl and csh foreach loops.
- c-comment module: Removes C and C++ style comments from a file.
- hash-comment module: Remove # style comments (as used in Perl and shell scripts) from a file.
- function module: Allows macros to be written which directly call Perl functions. This allows macros to give dynamic output.
- maths module: Implements basic maths functions including add, subtract, multiply, divide, sine, cosine, exponential, random etc.
- format module: Provides a list of functions for formatting text including a C/Perl style printf function and the Perl substr function.
- literal module: This module prevents macros appearing in strings being replaced.
- toupper module: Converts all lowercase letters in a file to uppercase.
- tolower module: Converts all uppercase letters in a file to lowercase.
- bigdef module: Enables multi-line macros to be defined without needing to put a line continuation character at the end of each line - makes large macros much more readable.
- bigfunc module: Same as bigdef, only difference is any keywords embedded in the macro are evaluated when the macro is replaced rather than when the macro is defined.
- defplus module: Enables existing macros to be appened to.
- blc module: Enables automatic line continuation if a closing bracket is on a line below the opening bracket.
- cmacro module: Makes certain macros more "C" like by putting quotes around their values.
- cpp module: Makes filepp behave as a basic C preprocessor.
- regexp module: Implements Perl style regular expression search and replacement, which allows regular expressions to be searched for and replaced with other strings.
- grab module: Used to grab input before any processing is done on it.
Enhancements:
- This release includes a rewrite of the processing chain so macros within macros behave correctly.
- Several other bugfixes and minor enhancements were made.

LogMiner is a powerful log analysis package for Apache (or other web servers using the combined log format).
LogMiner can extract and present several reports, about visits, hits, traffic, requests, navigation paths, browsers and OSs used by users and so on.
Data is stored in a PostgreSQL database, using a schema which has been optimized to reduce redundancy at minimum.
LogMiner has been inspired by the popular Webalizer package, but it differs in certain core points:
data is stored in a DBMS backend and reports are generated on-the-fly, while Webalizer generates plain html files. A DBMS allows to extract and aggregate data in many ways, whenever you need. A drawback is that you wont have the processing speed of Webalizer when parsing log files.
Webalizer only indexes the last 12 months of data: previous reports are still on disk, but arent accessible from any link. This is the most annoying thing of Webalizer, in my opinion: Im sick of having hundreds of unused files around
LogMiner allows to navigate to previous months easily.
Webalizer reports are hardcoded in the program. LogMiner implements reports in a more extensible way. Each report is in fact a simple PHP class, usually supported by a PL/pgSQL function (although youre free to insert your SQL queries in the PHP code if you like).
LogMiner offers more reports than Webalizer: for instance, the OS charts and the navigation graphs.
Depending on your needs, you might prefer LogMiner over Webalizer, especially if you like having a central SQL repository for your data which enables you to extract the data you need at any time, or to add a kind of report which wasnt planned from the start and apply it to older data.
If you dont have a PostgreSQL database or you expect to process huge log files in seconds, go for Webalizer.
Enhancements:
- This release adds support for libpqxx 2.6.9.
- SQL errors are now logged and dont interrupt the parsing of log files.

FreePOPs is a POP3 daemon plus a LUA interpreter and some extra libraries for HTTP and HTML parsing. FreePOPss main purpose is translating local POP3 requests to remote HTTP actions on the supported web-mails, but it is really more flexible.
For example there is a plugin to read news from a website as if they were mails in a mailbox. You can easily extend FreePOPs on the fly, without even restarting it. You can add a plugin or modify an existing one simply changing the script file since the plugins are written in LUA and are interpreted on the fly.
Main features:
Usage
FreePOPs can be useful in some situations, here we give the most obvious ones:
- You are behind a firewall that closes the 110 port but you need to read your mail and the web-mail of your mail provider sucks.
- Your mail provider does not allow you to access your mailbox with POP3 protocol, but only through the web-mail service.
- You prefer looking at your mailbox instead of browsing some websites news.
- You have to develop a pop3 server in less than a week and you want it to be reasonably fast and not so memory consuming.
- You are not a C hacker, but you want to benefit from a fast POP3 server frontend written in C and you want not to loose a month in writing the backend in C. LUA is a really simple and tiny language, one week is enough to learn it in a way that allows you to use it productively.
Features
FreePOPs is the only software we know with these features:
- POP3 server RFC compliant (not full featured but compliant).
- Portable (written in C and LUA that is written in C, so everything is written in the most portable language around the world).
- Small (in the sense of resources usage) and reasonably fast.
- Extremely extensible on the fly using a simple and power ful language.
- Pretty documented.
- Released under the GNU/GPL license (this means FreePOPs is Free Software).

Fly around, blast things and save the penguinoids.

Ogrian Carpet project is a 3D fantasy action/strategy game.
Ogrian Carpet is an outdoor first person shooter game with real time strategy elements, inspired by the game Magic Carpet.
It uses Ogre3D as the renderer and allows you to fly around an island casting spells, summoning monsters, collecting mana, and building castles.
The object of the game is to build a castle, collect mana, and destroy your enemies. To build a castle, select a location, look at the ground, and cast the build spell. Note, you cannot build castles very close to water or other castles.
Your castle starts out small, with only one turret. As more mana is added to your castle, it will gain more turrets. Each turret adds another crane to your castles defense and another spell to your arsenal.
Basically, the game consists of fighting for control of mana. Whenever you encounter another wizard, shoot them with fireballs. If you hit them enough, they will "die" and be sent back to their castle. You are then free to claim all the mana in the area for yourself.
Once all the mana has been claimed, attack your enemys castle to get mana out of it so you can claim it for yourself. Once you enemys castle is out of mana, you can eliminate it by killing its heart. When all of your opponents have been banished, youve won.
Enhancements:
- AI bot player for skirmish
- things can now be loaded from an image, rather then randomly
- option for old randomized maps
- trees can now always bee seen
- made castle mana drops aggregate more
- loosened the restrictions on summoning
- made the config menu better
- added victory conditions to skirmish: kill all enemy towers/castles
- made ticks and gnomes stay in the formation you put them in
- made monsters and towers drop less then their cost when they have no wizard
- made mana float higher
- made towers cheaper (50)
- made sentinels drop much less (3)
- changed speed behavior on lava maps
- added victory music
- new music
