Free minimalistic software for linux

Greenlines provides a login manager theme.

Greenlines is a set of lines drawn with SVG, and a minimalistic login manager in the upper right corner.

Some of the code is based upon Pirates of Gnome, I may fix up the code later on, because some of it is not that well thought through. Suggestions are welcome.

nPlot aims to be a minimalistic and easy-to-use data analysis application. The project currently features peak seeking, quadratic, cubic, linear and quart fittings.

Installation:

./configure
make
make install

Coindesigner is a RAD (rapid application development) system to build 3D applications using Coin3D openInventor.
Coindesigner allows to write simple 3D scenarios just using drag&drop, so users require no programming acknoledges at all to use it.
Coindesigner is a system equivalent to glade or qt-designer, where we can choose components from the openInventor toolkit, add them somewhere in our scene and configure them in a very easy way... and all changes are applied to the scene on the fly!
Main features:
- Reads and write scenes in native openInventor file format
- Can import geometry from VRML, 3ds, DXF, OFF (from geomview), SMF, sphere trees .SPH and XYZ point clouds file formats.
- Can export geometry to file formats VRML2, SMF, OBJ, STL, OFF y XYZ.
- It allows to visualize volumetric data (such as medical CT) if SIM Voleon is available in your system.
- Makes some basic geometrical operations, as mesh reduction (with QSLIM) and convex hull computation.
- It includes cdsview, an minimalistic external viewer that allows you to view and distribute scenes without need of coindesigner.
- Provides helpers to define colors (with QColorDialog), file paths (with QFileDialog), menus for enumerated types and much more...
- Allows to use manips to configure Lights and Transform nodes. Just use the right mouse button to interchange between those nodes and their manip!
- GUI has been translated to English, Spanish and Portuguese
- Includes the complete coin reference and several tutorials directly brownsables from the application.
- Its as multiplatform as coin3d and Qt are. It works under Linux, Mac OS X, and Windows.
- Its open source released under GPL license.

My File Manager is a small and lightweight file manager. It was developed to provide a small and fast file manager, which has only a few dependencies from other packages, but including some interestings things like mount partitions, minimalistic burning capability and mass renaming files. MFM use FLTK graphics toolkit.
Main features:
- Selectable shown fields (permissions, users, groups, date and size)
- Various sort options
- Rename group of files
- Change attributes of group of files
- Compress files
- Burn CD/DVD
- Find files by name or by content
- Mount/umount partitions

JVanish is a minimalistic 3D engine that implements a vanishing point projection (Fluchtpunktprojektion) based solely on standard Web technologies: JavaScript, XHTML, CSS, and SOAP.

JVanish projects goal is to find a generic and useful XHTML-based 3D widget set, while staying mostly lightweight in an AJAX Web environment.

FIAIF is an Intelligent Firewall.
Unlike many other scripts, FIAIF can be truly customized allowing multiple interfaces (or rather zones). There is no limit on the number of zones. All configuration is done through configuration files. There is no need to understand the script behind it all.
The script makes heavy use of state-full firewalling, and all RELATED and ESTABLISHED packets are accepted on all chains. If you wish to block something out, dont accept it in the first place.
The script is written in BASH. Though this is not the optimal programming language to use, it means that you do not need to install extra interpreters on your firewall. This allows you to have a minimalistic installation on your firewall.
Main features:
- TOS bit can be set per protocol/port basis. (To be used by traffic shaping).
- Limit syslog logging.
- Specification of multiple zones - One or more per interface.
- Load specific connection tracking modules (FTP, IRC etc.).
- Examination of /proc/sys/net setting, for possibly dangerous system configurations.
- Setup of linux runtime parameters.
- Run userdefined commands before and after applying the firewall.
- Syslog scanning, giving more human readable output based on setup.
Zones support:
- Handling of dynamic IPs (DHCP).
- Interfaces with multiple IP addresses.
- Allow/drop and/or reject packets hitting the firewall from the zone.
- Restrict the type of packets originating from the firewall itself.
- Restrict packets coming from other zones.
- Ban IPs within the zone.
- Ban MAC addresses within the zone.
- Watch traffic from a specific IP.
- Limit number of specific packets, e.g. to avoid DoS attack.
- Port forwarding, changing the destination IP and port, allowing e.g. a transparent proxy.
- Masquerading/SNAT.
- Traffic Shaping per interface.
- Ulogd logging support.
- Packet marking, for e.g. advanced routing.
- Definition of IP aliases, to ease maintenance and improve readability of configuration files.

Symlinker is a minimalistic file manager that is built to primarily operate with symlinks. The project is written in PHP.
Why would I use it?
There are many PHP hosting providers nowadays. Unfortunately most of them only provides you FTP to upload your files to their servers which imposes several restrictions on you.
You probably use a content management systems (CMS) on your site and you may want to make multiply installations of the same CMS. Such an installation traditionally involves duplicating the complete directory structure of your CMS, but that may take much disk space and its painful to upgrade the individual installations this way. There is a much better way.
You can solve this problem by placing the directory structure of your CMS in only one directory and symlink the individual CMS instances that you want to use to point to this particular directory. This is called a symlink farm. Unfortunately its not possible to handle symlinks with FTP because the FTP protocol doesnt have such commands that operate on symlinks.
This scenario is a perfect one where Symlinker comes handy.
How can I install it?
1. Download symlinker.php and put it somewhere under your webspace.
2. Set the $password variable in the beginning of symlinker.php. This will be your login password that Symlinker will ask you upon login.
3. You may also set the $default_path variable in the beginning of symlinker.php. This will be your default path after login.
How can I use it?
First, point your browser to the URL where you put symlinker.php. Symlinker will ask you the login password, so enter it correctly and log in.
If everything went well, you should see a page that resembles the picture that you can see on the right side. Lets see what operations you can use here:
- You can navigate in the directory tree by using the navigation bar which resides in the top left corner of the page or editing the path argument in the URL.
- You can create a new symlink by entering the filename and the target of the symlink into the upper text fields and pressing the symlink button.
- You can update the target of the symlinks of the current directory by editing the text fields related to the specific filenames and pressing the update button.
- You can log out by visiting the logout link which resides in the top right corner of the page.
How can I set up a symlink farm?
To better understand how to set up a symlink farm, take a look at the picture on the right side.
I use the MediaWiki content management system here. I have a special directory, /web/monda/apps where I keep the installations of the CMSes that I use.
First, I create a symlink with the filename mediawiki which points to ../../apps/mediawiki-1.9.3, the exact version of the MediaWiki installation which I want to use within this directory. Later when I want to upgrade MediaWiki, I can just rename the target of this symlink to point to a more recent version of MediaWiki.
As you can see, most of the filenames in this directory are symlinked to mediawiki, but some are not. This is because most CMS holds some data which are specific to the individual CMS instances so they must have their own separate directory.
Enhancements:
- Logout works correctly.
- Works with register_globals turned off for better security.
