Free screen savers software for linux

screen-scraper project is a tool used to extract data from web sites. You might use screen-scraper for the following purposes:
- Data Mining and Extraction
- Data Migration
- Application Integration
- Business Intelligence
- Web Task Automation
- Portal Components
- Meta-Searching
- Archiving
The screen-scraper application consists of two primary pieces:
- Workbench: A graphical user interface provides an intuitive approach that allows you to designate pages and specific pieces of information to be extracted.
- Server: After using the workbench to designate the data to be scraped, screen-scraper can be run in a server mode, much like a database. External applications can then connect to screen-scraper, which will pull data off of the designated web sites, then return them to the calling application. For example, you might build a web-based application using Active Server Pages (ASP) or PHP that invokes screen-scraper to search for products found on an external web site in real-time.
Additionally, screen-scraper can be started in a non-graphical mode from the command line such that it can be scheduled or invoked on-demand.
screen-scraper can automate many of the tasks typically required when scraping data from web pages, such as tracking cookies, logging in to web sites, and traversing search results pages.
Depending on the programming languages and platforms you most prefer, screen-scraper is likely to be familiar to you. screen-scraper contains an internal scripting engine that supports:
- VBScript
- JScript
- Perl
- Interpreted Java
- JavaScript
- Python
When invoking screen-scraper externally take your pick from the following languages:
- Java
- PHP
- Anything COM-based (such as Active Server Pages, Visual Basic, and Visual C++)
- .NET (both Microsoft-based and Mono)
- Cold Fusion
Enhancements:
- Several bugfixes and minor features have been added, including automatic backup of the database, enhanced HTML rendering and HTML stripping, fixing an error that caused duplicate scripts to appear at times on import, and fixing multiple errors relating to international character sets and non-ASCII characters.

A screenshot, screen capture, or screen dump is an image taken by the computer to record the visible items on the monitor or another visual output device. Usually this is a digital image taken by the host operating system or software running on the computer device, but it can also be a capture made by a camera or a device intercepting the video output of the computer.

Screenshots, screen dumps, or screen captures can be used to demonstrate a program, a particular problem a user might be having or generally when computer output needs to be shown to others or archived.

Screenie is a small and lightweight screen frontend that is designed to be a session handler that simplifies the process of administrating detached jobs by providing an interactive menu.

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.

Backgroundimage Saver is a Firefox extension that provides help for an annoying technique that can be found on more and more pages. That is to hide images behind a transparent gif to protect them against being saved.

Examplepages that use this can be found at:

print.google.com (just try to save any bookpage that is displayed after selecting a book)

www.imdb.com (same here with any larger images that are displayed)

Because since these pages place a transparent gif on top of the real graphic you cant just right-click an image and select "Save Image As..." because then you would just save the transparent gif (which is probably not what you want.

So this simple extension just adds a Save Background Image option to the right click context menu which does the trick.

Furthermore it is helpful if you want to be able to directly save the backgroundimage, since Firefox does not offer this option by default.

Why shouldnt i use the Browsers SAVE PAGE.. function?
I did it like this and lost soon the overview. Its always a complete site that is saved -even if you are just interested in one simple sentence! And these large files are scattered all over your harddisc and its uncomfortable to find them or to search within them.

Why shouldnt i use other tools?
Hey! You can use whatever you like. But they all depend on a special operating system or a special browser or they are just expensive. Through the renouncement on platform specific functions, the WEB INFORMATION SAVER is able to run on all major operating systems like Windows, Linux, Unix, MAC OS X etc.
