Math::Combinatorics is a Perl module that can perform combinations and permutations on lists.

SYNOPSIS

Available as an object oriented API.

use Math::Combinatorics;

my @n = qw(a b c);
my $combinat = Math::Combinatorics->new(count => 2,
data => [@n],
);

print "combinations of 2 from: ".join(" ",@n)."n";
print "------------------------".("--" x scalar(@n))."n";
while(my @combo = $combinat->next_combination){
print join( , @combo)."n";
}

print "n";

print "permutations of 3 from: ".join(" ",@n)."n";
print "------------------------".("--" x scalar(@n))."n";
while(my @permu = $combinat->next_permutation){
print join( , @permu)."n";
}

output:

Or available via exported functions permute, combine, and factorial.

use Math::Combinatorics;

my @n = qw(a b c);
print "combinations of 2 from: ".join(" ",@n)."n";
print "------------------------".("--" x scalar(@n))."n";
print join("n", map { join " ", @$_ } combine(2,@n)),"n";
print "n";
print "permutations of 3 from: ".join(" ",@n)."n";
print "------------------------".("--" x scalar(@n))."n";
print join("n", map { join " ", @$_ } permute(@n)),"n";

Output:

combinations of 2 from: a b c
------------------------------
a b
a c
b c

permutations of 3 from: a b c
------------------------------
a b c
a c b
b a c
b c a
c a b
c b a

Output from both types of calls is the same, but the object-oriented approach consumes much less memory for large sets.

Krystal Drop project is a free clone of NeoGeos Magical Drop.

In it, you play on a field on which lines of gems are being dropped by the top of the screen, at a regular basis or when your opponent makes a combo. You can take or drop gems from the bottom of the screen to make gems disappear.

If you move gems in order to create a vertical alignment of at least three gems of the same colour, they will burst and start a chain reaction with all neighbouring matching gems.

The aim is to prepare some other chain reactions while the first gems are bursting, in order to make a combo and send lines to your opponent. You lose when some gems reach the bottom of the field.

mysqlCart provides a template based dynamic e- commerce shop system.

It does not require any modules or rely on interpreted languages and is very fast even on older machines.

Finally a template driven -pure C with mySQL C API-, very fast and easy on your CPU and RAM GPL ecommerce solution. The mysqlCart/mysqlShop admin/dynamic site combo is from the world leaders in GPL ISP software OpenISP, and it is FREE (more so GPL free! www.fsf.org)

This ecommerce solution gives you the edge over clunky perl (shudder!) or pain in the ... php installation nightmare and interpreted lameness. And phps awkward syntax tries to be like C (php is written in C, but study its history and come to your own conclusions about its usefulness for heavy traffic sites,) so why bother?

To be fair php is great for certain things but C is much better for mySQL cgis. All unix type OSs, including Linux/FreeBSD/OpenBSD and Solaris are written in C.

Dataxi project is a collection of tools for developing form-based information systems. Dataxi enables one to quickly build an application based on forms with which the user can access the underlying database in order to query, read, edit and write. Dataxi is the link between the user interface and the database.
Dataxi is an OS and enviroment independent product. It follows HTML and SQL standards to such extend that interoperability with all browsers and database backends should be supported.
Dataxi runs on all major operating systems as is or only with minor changes in ini -files.
The purpose of Dataxi is to take the pain away from the most boring phase in the data access application development: user interface designing and programming. Ones you have defined the layout of the form and location for columns, you are done, unless you prefer setting data validation and output format features and other niceties.
A database is a structured collection of data. It may be anything from a simple shopping list to a picture gallery or the vast amounts of information in a corporate network. To add, access, and process data stored in a computer database, you need a database management system such as MySQL. Since computers are very good at handling large amounts of data, database management plays a central role in computing, as stand-alone utilities, or as parts of other applications.
Enhancements:
- This version works with both PHP 4 and 5.

gShield is an aggressive, modular, ipchains-based firewall script. gShieldConf is a small program to edit the configuration files for it. It is written using the gtk toolkit. It is released under the GNU GPL.
Please note, gShield must be installed prior to running gshieldconf. The program will load (and save) the gShield configuration file(s). It uses the contents of the file to determine the settings for the user interface. Anything defined in the user interface but not in the conf file can be changed, but the changes will not be saved after that.
Main features:
- Simple and easy to see the firewall configuration at a glance.
- Preserves unknown variables.
- Preserves comments and formatting of conf files
- Easy to extend when the conf file is changed.
Version restrictions:
- No way to activate the changes that have been made (ie, run gShield.rc).
- The conf files must be installed before running gshieldconf. In other words you cannot use gshieldconf to create a new script.
- No revert/undo operation. It is actually rather easy to support a single level of undo. I may do this at some point.
- Doesnt actually check to see if there have been any changes before saving the config files out.
- The Firewall Root directory must exist, it will not be creat
Enhancements:
- Removed Save As and Load menu items/code. I have done this because it was an ill conceived feature and doesnt make sense anymore.
- Made it compile and work with both libxml1 and libxml2.
- Removed last vestiges of hard coded file paths (specifically the paths to the gShield configuration files).
- Seperated the program from the controls.xml file. This was done to better be able to maintain the controls.xml file and to support multiple versions of gShield.
- Added a new UI control type, the combo box. This is to support the tri-state fields in gShield2.6 and up.
- The structure of controls.xml has changed a bit. Mostly added a new node type, Configfiles to specify the locations of the files to be loaded.

Dystopia is a Half-Life 2 modifcation which places the player into tense combat situations in a high tech world spanned by computer networks. As either Punks or Corp Mercenaries the player will fight through the physical world to gain access, via jack-in terminals, to cyberspace.

Cyberspace is a three dimensional representation of the worlds network. Inside cyberspace players will launch programs to hack into systems linked to the physical world, fight off enemy hackers or defend critical systems. Gameplay progresses through inter-linked physical and cyberspace objectives, some are completed in either the physical world or cyberspace, others only by a well timed combination of the two.

The player will be immersed in action packed battles, whether as a heavily augmented combat mercenary armed to the teeth with the latest in firepower and implants, or a twitch reflex cyberdecker racing to infiltrate a cyberspace node. Only through skillful use of the high tech arsenal were making available and intelligent team play will players truly jack-in and kick ass.

Note: System used was Ubuntu Breezy Badger 2.6.12-9

Installation:

Log in as root

Create a user (EX. hlds, dystopia, srcds, etc..) with the command:

adduser hlds

Give that user a password

passwd hlds

Create a directory somewhere as that user where the server files and game files will go and go to that directory

mkdir /home/hlds/srcds

Make the owner of that directory your new user

chown hlds /home/hlds/srcds

Either login as that user or change to that user with the command

su hlds

Get the linux hlds update tool accurate as of 2/22/07

wget http://storefront.steampowered.com/download/hldsupdatetool.bin

Change the file to be executable

chmod ugo+x hldsupdatetool.bin

Run the hldsupdatetool.bin

./hldsupdatetool.bin

If you see an error about not finding /bin/uncompress type

ln -s /bin/gunzip /bin/uncompress && ./hldsupdatetool.bin

Answer the agreement
Run the steam file that is extracted

./steam

It will update itself and then tell you to rerun the command, do so, but changed. This will take a while

./steam -command update -game hl2mp -dir .

Download the Dystopia V1 server package

wget dystopia_v1_server.tar.gz

Extract the files in your srcds folder

tar -xvzf dystopia_v1_server.tar.gz

Configuration:

Edit ~/srcds/dystopia/cfg/server.cfg with your editor of choice. This file is run at every map change.

Comment out or remove the following line.

map dys_assemble

This must be done or you server will not start properly.
Edit ~/srcds/dystopia/cfg/valve.rc with your editor of choice. This file is run at server start

Add in the line the following line.

map dys_assemble

This map can be whatever you like your server to start on. If you do not do this, your server will not start properly.
Edit ~/srcds/dystopia/motd.txt with your editor of choice
Edit ~/srcds/dystopia/mapcycle.txt with your editor of choice

Starting the Server - Basic

Go to your srcds directory, whatever it is named

cd ~/srcds

Use the following command to start your server, this is a basic setup, replace 1.1.1.1 with the ip you want your server to report. You can also leave out the +ip 1.1.1.1 and it will take the first IP it can get

./srcds_run -game dystopia_v1 +maxplayers 20 -ip 1.1.1.1 -port 27015 &

To bring the console back so you can type commands into the console. use the command

fg

This will not always work.

The drawback to this method is that once you start it and then exit your ssh session you will not be able to get it back (at least I dont know of a way, if you do, let me know and Ill add it)

Starting the server - Advanced

Check to see if you have the screen command

screen

If you do, proceed, if not, get it. Create a shell script with the following commands. To do so, open a file in your favorite text editor (*nix only please). I named the file serverStart.sh

#!/bin/sh echo "Starting Dystopia Beta Server" sleep 1 cd /home/hlds/srcds screen -A -m -S dystopia /home/hlds/srcds/srcds_run -game dystopia_v1 +maxplayers 20 -ip 1.1.1.1 -port 27015

Make the shell script executable

chmod ugo+x serverStart.sh

Once its up and running, to exit the screen without closing it use the following key combo

ctrl+A,D (ctrl+A and then while still holding a, press d)

To retrieve the screen so that you can look at the console

screen -r

DenyHosts is a script intended to be run by Linux system administrators to help thwart ssh server attacks.
If youve ever looked at your ssh log (/var/log/secure on Redhat, /var/log/auth.log on Mandrake, etc...) you may be alarmed to see how many hackers attempted to gain access to your server. Hopefully, none of them were successful (but then again, how would you know?). Wouldnt it be better to automatically prevent that attacker from continuing to gain entry into your system?
DenyHosts attempts to address the above... and more.
Main features:
- Parses /var/log/secure to find all login attempts and filters failed and successful attempts.
- Can be run from the command line, cron or as a daemon (new in 0.9)
- Records all failed login attempts for the user and offending host
- For each host that exceeds a threshold count, records the evil host
- Keeps track of each non-existent user (eg. sdadasd) when a login attempt failed.
- Keeps track of each existing user (eg. root) when a login attempt failed.
- Keeps track of each offending host (with 0.8+ these hosts can be purged if the associated entry in /etc/hosts.deny is expired)
- Keeps track of suspicious logins (that is, logins that were successful for a host that had many login failures)
- Keeps track of the file offset, so that you can reparse the same file (/var/log/secure) continuously (until it is rotated).
- When the log file is rotated, the script will detect it and parse from the beginning.
- Appends /etc/hosts.deny and adds the newly banned hosts
- Optionally sends an email of newly banned hosts and suspicious logins.
- Keeps a history of all user, host, user/host combo and suspicious logins encountered which includes the data and number of corresponding failed login attempts.
- Maintains failed valid and invalid user login attempts in separate files, such that it is easy to see which valid user is under attack (which would give you the opportunity to remove the account, change the password or change its default shell to something like /sbin/nologin
- Upon each run, the script will load the previously saved data and re-use it to append new failures.
- Resolves IP addresses to hostnames, if available (new in v0.6.0).
- /etc/hosts.deny entries can be expired (purge) at a user specified time (new in 0.8)
- FreeBSD support (added in 0.7)
