2 trial software / shareware for linux

Zynx is a fun arcade-style game. Your objective is to pop all of the dots in a maze while avoiding the monsters. If you can catch the elusive power-up star, the roles are reversed and the monsters must avoid you or be destroyed.

Zynx is shareware. You can download the game for free and immediately start playing. However, only 10 levels are playable.

To play the rest of the game, you must register. Registered users receive a registration code that unlocks all 50 levels of Zynx.

TuxShop is a modern point of sale and retail management application, that is supported on Linux and Windows-xp. It is feature packed yet still manages to provide an interface that is as simpler than a cash register to operate.
And yes, its now free as intended by the GPL, you are encouraged to make donations though. Making a donation will add you to my list of supported clients, you then get priority support, and if your donation exceeds ZAR 1000.00 p/a I will even send you up to three CDs with the latest major release for that year.
Supported clients are also notified of any bugs and fixes via email as they occur.
Enhancements:
- This release added a facility to order departments and inventory items on touch displays, the ability to specify change sent for take out orders with delivery, support for returnable items and a report for outstanding returnables, support for "Days to Renewal" on inventory items, and mailing of renewal notifications.
- The layout for templates and help was changed so more scenarios work straight out the box.
- Problems where it was possible to add inventory without a code or description were fixed.

The PowerML product suite provides a foundation for Java- and XML-based PowerPoint document management.
Supported PowerPoint features include complete text formatting, speakers notes, comments, most shape types (with parameters), shape styles (fills, line styles, shadows, 3D), pictures (JPG, PNG, EMF, WMF, DIB, PICT), presentation structure (masters, slides, shape groups, placeholders, etc.), document summary (title, author, company, preview picture, etc.), and Unicode support.
Enhancements:
- This version supports hyperlinks: either internal links, which point to presentation slides, or external links, which can be URLs or files.

aiSee reads a textual, easy-to-read and easy-to-learn graph specification and automatically calculates a customizable graph layout. This layout is then displayed, and can be interactively explored, printed and exported to various graphic formats.
aiSee has been optimized to handle huge graphs automatically generated by applications. It is available for Windows, Linux, Solaris, and Mac OS X.
When working with any kind of complex relational data, visualization provides for much better and faster understanding. Back in 1991, aiSee was developed to visualize the internal data structures typically found in compilers.
Today it is widely used in many different areas:
- Genealogy (family trees, evolution diagrams, pedigrees)
- Business management (organization charts)
- Software development (call graphs, control flow graphs)
- Hardware design (circuit diagrams, finite state diagrams)
- Database management (entity relationship diagrams)
- Informatics (algorithm visualization)
- Web design (sitemaps, P2P networks)
Main features:
Excellent readability of calculated layouts:
- Nodes are placed in a hierarchy of layers
- Nodes are positioned without overlapping
- Crossing of lines (edges) is reduced/avoided
- Edges are kept short and straight
Fast layout calculation for huge graphs
15 basic layout algorithms, including
- Force-directed layout
- Depth-first-search layout
- Specialized algorithm for layout of trees
Zooming of graphs and easy navigation
Easy printing of graphs on multiple pages
Export of graphs to BMP, colored PostScript, SVG, PNG and HTML
Graph nesting and advanced graph hierarchy operations like
- Folding, unfolding, wrapping and clustering of complete subgraphs
- Folding of user-defined graph regions
- Excluding subgraphs or graph regions
- Hiding of edges
Cartesian and polar fish-eye views
Animation of series of graphs and smooth transitions
Multi-line edge labels
Easy handling of huge graphs with as many as 1,000,000 nodes and 1,500,000 edges
- Commands, hyperlinks, JavaScript functionality, and up to three additional information windows can be associated with each node and each subgraph
Nodes can be represented by user-defined bitmap icons
- The input format GDL (graph description language) provides for very natural textual graph representation, and is also easy to learn.
Version restrictions:
- 30-day trial version
Enhancements:
- Improved export of edges to bitmap formats.
- Improved export to SVG: the output files are now up to 14% smaller.
- Fixed bitmap image mapping bug.
- Fixed bugs in the Show Neighbors implementation.
- Fixed bugs in the Follow Edge implementation.
- Fixed export of f- to SVG.
- Other bugfixes.

JLicense is a Java utility library for validating and creating license keys. It includes a simple GUI tool for creating the license file and a LicenseManager (which should be embeded inside your Java software) for validating the license.

You can also write your own class, such as a Servlet, to create the license file more dynamically based on user input data.

JLicense is feature based, and you can validate the license based on the features. For example, you can add features like IP address, MAC address, user number etc.

Silmar is a random dungeon game for Linux, Mac OS X and Windows 9x/ME/XP.

Battle your way through the dungeon levels underneath the razed tower of the evil archmage Syrilboltus, questing for riches with which to rebuild your devastated homelands.

Use the powers you acquire as you gain experience to avoid or defeat the foes you encounter along the way. With randomly generated levels (accompanied by occasional fixed levels), no two games are the same!
