Free option to software for linux

Options.pm is a command-line option-parsing Perl module meant to imitate the syntax of the t.p.usage.Options module from the Twisted Python library.

This module will allow you to specify which options to look for on the command line, and supports both long and short versions of simple flags and parameters. If a required parameter is unspecified, Options.pm will print nicely formatted usage information with the error.

App::Options is Perl module to combine command line options, environment vars, and option file values (for program configuration).

SYNOPSIS

#!/usr/local/bin/perl

use App::Options; # reads option values into %App::options by default

# do something with the options (in %App::options)
use DBI;
$dsn = "dbi:mysql:database=$App::options{dbname}";
$dbh = DBI->connect($dsn, $App::options{dbuser}, $App::options{dbpass});
...

Get help from the command line (assuming program is named "prog") ...

prog -?

Option values may be provided on the command line, in environment variables, and option files. (i.e. $ENV{APP_DBNAME} would set the value of %App::options{dbname} by default.)

The "dbname" and other options could also be set in one of the following configuration files

$HOME/.app/prog.conf
$HOME/.app/app.conf
$PROGDIR/prog.conf
$PROGDIR/app.conf
$PREFIX/etc/app/prog.conf
$PREFIX/etc/app/app.conf
/etc/app/app.conf

with a file format like

[prog]
dbname = prod
dbuser = scott
dbpass = tiger

See below for a more detailed explanation of these and other advanced features.

App::Options combines command-line arguments, environment variables, option files, and program defaults to produce a hash of option values.

Compact Filter is a network packet filter for Linux. It features an easy-to-use compact filter representation and high performance.
The main features are: easy to use interface, compact filter representation (memory efficient), and very high performance.
A difference between CF and other firewalls, such as Netfilter, is its representation of the ruleset. In CF the user writes a filter which is then compiled and optimized in user-space. The optimized filter is then loaded into the kernel (using netlink). Consequently the in kernel packet filtering code only needs funtionality for setting up a filter and filtering packets, while the more complex code of optimizing the filter remains in user-space.
Because of the continuous increase of the bandwidth and the security threats, firewalls have to evolve towards more efficient filtering schemes. The truth is that the existing scheme does not scale so well with the combined growth of bandwidth and rulesets.
Our aim is to try another approach to perform packet filtering where we minimize the complexity of the filtering process. This result in, both, a reduction of the required CPU power to filter packets and a simpler (and smaller) kernel code. Of course, we are pushing all the smart and complex part out to the user-space, but, developing in user-space is much simpler and safer.
Enhancements:
- changed -d option to delete all filters
- added -D option to delete a specific filter
- changed default policy to permit rather than deny
- added -l option on flex to support --yylineno on older versions of flex
- new and improved install guide

TiWarriors project is an Asteroids clone with multiplayer support and incremental ship control.
Two things differ from the original: energy control and multiplayer mode.
Enhancements:
- added some config options like antialiasing and the option to switch to full screen or window mode.

Sudokut is a command line solver for Sudoku puzzles. When supplied with a Sudoku string or file, it returns all possible solutions.
Sudokut takes approximately half a second to solve a medium force Sudoku by using an efficient algorithm that is guaranteed to find all the solutions. It accepts many options that implement various features (validity check, diff, suggestions, and probing).
Enhancements:
- two new solving techniques are supported: naked triplets reduction, hidden triplets reduction
- new -u option to test the unicity of the solution
- new -m option to modify the string

Camera Monitor is a little tray system icon that notifies you when your Webcam is on. The project is designed for the GNOME desktop, but will work as well on KDE and XFCE.
Camera Monitor is released under the terms of the GNU General Public License.
Installation:
tar xzf laptoptemp-0.2.tar.gz
cd cameramonitor-0.1
./configure
sudo make install
Enhancements:
- Added support for libnotify
- Ported to new gtk.StatusIcon
- Updated preferences panel
- Updated about information
- Removed notification on bad previous exit
- Added option to preferences for autostarting cameramonitor every session

Net::FreeDB2::Connection is a FreeDB/CDDB abstract connection class.

Net::FreeDB2::Connection is an abstract class to represent connections to FreeDB/CDDB servers. After a successfull connection, FreeDB/CDDB queries, reads etc can be made to obtain/provide information from/to FreeDB/CDDB databases.

CONSTRUCTOR

new (OPT_HASH_REF)

Creates a new Net::FreeDB2::Connection object. By default connect () is called to initiate the connection but see option no_connect. See the implementation for complements/restrictions.

Options for OPT_HASH_REF may include:

client_name

Mandatory option to name the connecting client software.

client_version

Mandatory option with the client software version string.

client_host

The hostname of the client. Defaults to &Sys::Hostname::hostname ().

client_user

The user of the client. Defaults to scalar (getpwuid ($>));

freedb_host

The FreeDB/CDDB host. Defaults to freedb.freedb.org.

freedb_port

The port on the FreeDB/CDDB host.

proxy_host

Proxy host.

proxy_port

Port on the proxy host. Defaults to 8080.

proxy_user

Proxy user name to use.

proxy_passwd

Proxy password to use.

no_connect

Do not call connect () during instanciation.

TrashMail.net is a Firefox extension that creates free disposable email addresses and pastes them directly in forms.

This helps to protect you from spam mails and could be useful when subscribing to forums or newsletters.

The email addresses can be deleted at any time!

This plugin uses the free TrashMail.net DEA service.

Guide to use this extension:

Click the right mouse button in an editable field. A menu will appear with the option to paste a disposable email address.
