Free hatch software for linux

reset-screen is a very simple Qt 4 program that displays a simple cross hatch pattern on your monitor.

Why is this useful? Well, it makes the auto-sync feature of the flat panel LCD monitors out there both faster and more accurate (well, for mine anyways).

I have to run this every other time I start KDE so I figure others may find it useful as well.

This isnt really useful for laptop users I think, but you may need it. Who knows? :)

This is a very simple program, which a very simple build system.

Roadnav is an in-car navigation system that can run on a variety of operating systems like Linux, Windows, and Mac OS X.
Roadnav can obtain a cars present location from a GPS unit, plot street maps of the area, and provide verbal turn by turn directions to any location in the USA.
Roadnav uses the free TIGER/Line files from the US Census Bureau to build the maps, along with the GNIS state and topical gazetteer data from the USGS to identify locations.
Main features:
- Generates street level maps for the US
- Interfaces with GPS units to display your position in real time
- Verbal turn by turn directions to any place in the US. Automatically recomputes directions if you miss a turn.
- On screen keyboard
- 3D (drivers perspective) view mode
- Daytime and nighttime color schemes
- Automatic day/night mode switching
- Plots nearby landmarks and points of interest
- Can operate offline (without an Internet connection)
- Antialiased output
- Supports multiple operating systems including Windows, Linux, and Mac OS X
- Uses freely available data from the US Census Bureau and the USGS
- Appearance can be customized with skins
- Can output status information to LCD devices through LCDproc
Enhancements:
Enhancements:
- Adds option to Preferences to enable gpsd buffering (reduces jitter).
- Adds experimental GPX import support.
- Disk usage reduced by ~30%.
- Adds GPS serial initialization string option to Preferences.
- Adds preference to override default map directory.
- Adds option for username/password proxy authentication.
- Adds "Use System Proxy Settings" preference, which reads proxy settings from the HTTP_PROXY environmental variable.
Bug Fixes:
- Fixes Delete button in Waypoints dialog when no waypoints exist.
- Workaround for buggy serial implementations.
- Fixes Windows 2000 compatibility.
- Fixes i18n issue in OSM code.
- Improved address look up.
- Eliminates IPP error messages when printer is not configured.
- Improved compatibility with DeLorme Tripmate and Earthmate GPS units.
- Win32 floating point model changed from fast to precise. Should resolve problems calculating routes.
- Fixes focusing issue in keyboard dialog.
Developer Visible Changes:
- MapControlData_Tiles index files eliminated.
- Direct access to Point::m_fLong and Point::m_fLat eliminated. Use the Point::Set* and Point::Get* functions instead.
Misc:
- Compiled maps now organized in a more human readable format.
- Eliminates TIGER/Line 2006 First Edition from search path.
- Proxy settings now on their own preferences page.
- When maps have to be upgraded, adds option to not upgrade map files and immediately terminate Roadnav instead.
- Small map labels now have a solid background instead of a cross hatch.

jPicEdt is a multi-platform vector-based graphic editor for LaTeX and related packages, including eepic and PsTricks.
The LaTeX picture environment is a special environment for inserting simple drawing commands into a LaTeX file.
This environment was obviously not intented to replace more sophisticated graphical formats such as Postscript or PDF (and their associated design tools: Adobe Illustrator, Macromedia Freehand,...), but was merely aimed at easily incorporating small and simple drawings (e.g. graphs, electrical schematics,...)
Yet picture commands are flexible enough to allow one to build rather complicated drawings, including circles, rectangles, lines and vectors, bezier splines.
Besides, using epic/eepic or PsTricks packages largely increases the set of available commands, and amongst other things, allows for shape-filling (and colours with PsTricks) and a better rendering of shapes.
Finally, one of the main benefits of using the picture environment is the ability to incorporate text containing any LaTeX command allowed in LR mode, e.g. equations, arrays or user-defined commands.
Main features:
- Every graphical element allowed by the picture environment commands: lines, arrows, circles, boxes.
- Emulated elements, for example lines of any slope (which LaTeX doesnt support natively), circles of any size, ellipses, arcs and polygons. This makes a strong use of the multiput command.
- Nearly every object allowed by the epic/eepic packages (excluding grids and textured filling): dashed lines, filled (whitened, blackened or shaded) ellipses or polygons, arcs,... Using this package is optional.
- Starting from version 1.3.2, nearly every object in the pstricks.sty package (this include : filling with colors, hatches, textures, setting various stroke parameters, rotating texts,...). Support for pst-node.sty and other related packages is either experimental (meaning that you must recompile with a boolean flag turned on) or simply underway.
