Free light on software for linux

LightZone is a proprietary photo browser and editor for Mac OS, Windows, and Linux. Its like Photoshop and The Gimp, but its easier to use and focused on photography.

LightZone photo editor features raw file support, high-fidelity color space management, color-managed printing and completely non-destructive editing

The Linux tarball is a complete binary including a manual and a Sun Java JRE. It requires no privileges and runs no install scripts.

LightZone is a proprietary photo editor developed by Light Crafts, Inc. of Palo Alto, CA.

light-monitor is a transparent panel that depends only on X and Xft. The project comes with light-calendar, a simple, transparent, and lightweight calendar.
These two programs are written to consume the lowest possible amount of resources.
Main features:
- vol Manages the volume (pcm and vol). To change the current volume just clic on it or use the mouse-wheel.
- cpufreq Manages the scaling_governor : blue means powersave, blue and green means ondemand, and blue green and red stands for performance. To change to the next one, just clic on the processor
- load Shows the current load on the system and the processor temperature
- time Shows the time
- date Shows the date
- network Shows the cumulative bandwidth over all network interfaces except lo. It is hidden if current upload and download are null
- ac Shows if the power supply is plugged for laptop
- battery Shows the current percentage of remaining charge in the battery if it is not full. IF ac is unplugged, it shows an estimation of the remaining time too.
Light-calendar
light-calendar is a simple, transparent, and lightweight calendar (12Ko). It is distributed under the license GPLv2.
To see the next month, click on the right arrow. The previous month is accessible using the left one. To come back to the current month, use the o between the two arrows. You can move it by dragging it outside those buttons.
Enhancements:
- The semantic of buttons were changed.
- Now when a button is clicked, its window is redrawn.
- A bug in the config file reader that sometimes duplicated the last widget was fixed.
- The cpufreq applet is now more reactive.
- The README was updated.

Light Speed! project is an interactive relativistic simulator.
Light Speed! is an OpenGL-based program which illustrates the effects of special relativity on the appearance of moving objects.
When an object accelerates past a few million meters per second, these effects begin to grow noticeable, becoming more and more pronounced as the speed of light is approached.
These relativistic effects are viewpoint-dependent, and include shifts in length, object hue, brightness and shape.
Main features:
- Real-time interactive viewing
- 3D object importer
- Snapshot exporter
- Special Relativity Scene (SRS) exporter
- Reference geometry
- Independent toggles for the four relativistic effects
- Numerical camera location + target readout and input
- Switchable background color

Q Light Controller 2 (QLC) aims to be a free alternative to commercial lighting software and hardware. The main emphasis is to build a software that can be used to control any kinds of lighting equipment.
QLC uses the dmx4linux driver suite to access various hardware interfaces. Currently DMX512, Analog 0-10V and MIDI control systems are being supported by dmx4linux. Refer to dmx4linux interfaces for more information on supported interfaces.
Q Light Controller is free software licensed under the GNU General Public License.
Main features:
- Easy to use device-oriented interface
- Control up to 512 DMX/Analog channels thru DMX4Linux
- Use one of the ready-made fixture definitions, or
- Define your own fixtures with the device class editor
- Create fast changing or smoothly fading scenes, chasers and sequences
- Easy programming of moving lights thru a pattern generator
- Conjure your favourite lighting desk layout with the virtual console

Hogwash Light BR is an Intrusion Prevention System that can filter packets directly in the layer 2 of the OSI model (so the machine doesnt need even an IP address).
Detection of malicious/anomalous traffic is done by rules based in signatures, and the user can add more rules. It is an efficient and versatile IPS, and it can even be used as bridge to honeypots and honeynets.
Since it doesnt make use of the operating systems TCP/IP stack, it can be "invisible" to network access and attackers.
Enhancements:
- New rules were added.

SVN-RaWeb-Light is a Perl module, that once installed and driven by a CGI script provides a lightweight Web-based browser for remote Subversion repositories, not unlike the default HTML one for http:// repositories. (with some improvements).

If you deploy this module in a public URL with a good bandwidth, let me know so I can link to it here for demonstration purposes.
