Free progressive software for linux

Ekspos is platform independent Java image viewer program. Ekspos Image Viewer support most popular image format: PNG, JPEG, and GIF, where additional image format can be added through Java ImageIO plugin.
It consists of 2 parts: shell browser and viewer. Shell browser allows you to navigate your image collection and youll be able to browse images in tree, detail, list, icon and thumbnail view. The viewer provide progressive view of images with zoom and pan capability.
Main features:
- Image Format (Default): JPEG, PNG, and GIF
- Support ImageIO plugin for additional Image Format
- Support 4 views: detail, list, icon, and thumbnail
- Thumbnail caching for fast preview
- Written entirely in Java

KmPg2 is a very simple to use MPEG2 encoding wizard that allows the user to create high quality DVD compatible MPEG2 streams, without requiring any technical knowledge.
Creating high quality MPEG2 streams involves a lot more than simply feeding the input video to mpeg2enc/transcode/mencoder/etc.
The input video needs to be carefully prepared by pulling it through a chain of stream processing tools like low-pass filters, color correction filters, static and dynamic chroma and luma noise filters, scalers, and so on.
This processing chain needs to be tuned in such a way that all irrelevant data (like noise) is removed before the video enters the encoder. KmPg2 uses the video processing / encoding tools from the MJPEGTools project to achieve this.
KmPg2 features a profiler that enables the user to interactively create custom pre-processing pipelines that are optimised for a specific type of video material. These preprocessing pipelines (profiles) can be stored and used with the actual encoding wizard.
For example, you could create a profile that is designed especially for restoring a single aging VHS tape, or you could create a profile tuned for your digital camcorder and re-use it for every new recording that needs to be encoded.
At this moment KmPg2 accepts only one format of input video: Raw Sony DV video streams. This is the video format that most people use nowadays for high quality video processing and editing. Support for using AVI files for input is expected in future versions.
Main features:
- Produces DVD compliant MPEG2 streams
- Seperate chroma/luma noise filtering
- Low-Pass filtering support
- Contrast/Brightness/Saturation correction
- White balance correction
- Special black-and-white mode
- Crop image to Widescreen (16:9) or Panavision (2.35:1)
- Output conforms to Rec.601 specifications
- Both constant bitrate and variable bitrate encoding
- Unsharp masking
- Supports progressive and interlaced source material
- Support for removing overscan area
- Provides feedback to user about average/peak bitrates
- Show output on screen while encoding
- Generate encoding shell scripts
- Generate quick preview-encodings of parts of source video

Webicals goal is to create a webapplication that allows somebody to manage (view, edit, share, invite) multiple WebDAV hosted calendars, based on the iCalendar standard.

Its features include progressive enhancement, a plugin framework that can be used to enhance the GUI and the back end providers, pluggable authentication, and i18n.

Dutch and English localizations are provided, and adding more locales is easy. You need a servlet container, such as Apache Tomcat, to run it.

Bulli Epu is an interactive program for generating parquet deformations (tilings with progressive changes across the pattern).

There is both a free version and, for a small donation, one with a few extra features. Both are written in Java and run via Java Web-Start.

Trend is a general-purpose, efficient trend graph for "live" data. Data is read in ASCII form from a file or continuously from a FIFO and displayed in real-time into a multi-pass trend (much like a CRT oscilloscope). trend can be used as a rapid analysis tool for progressive or time-based data series together with trivial scripting.
Main features:
- OpenGL graphics
- Automatic or fixed graph scaling
- Two graph scrolling and shading modes
- Configurable colours/grid
- Flexible input
- Interactivity

The jEdit Ruby Editor Plugin lets you manipulate Ruby and Rails code at the syntax level.
Ruby Editor Plugin focused on programmer productivity, the plugin provides method completion and an integrated Ruby documentation viewer.
Main features:
- Syntax parsing now supports single-line modules, classes & defs
- Ruby Docs Viewer contains Ruby on Rails docs
- Variable method completion for Ruby on Rails methods
- Auto-indent and insert end now works for if( and if ( patterns
Enhancements:
- "Introduce variable" refactoring was added.
- Copy and cut actions that operate on a whole line when no text is selected were added.
- Autocompletion of brackets and quotes is now smarter.
- Progressive selection now handles method selection better.
