Free satellite zooming software for linux

Satellite can track many remote machines with dynamic IP addresses in situations where public DNS services are inappropriate. Satellite can log and alert an admin immediately when a site comes online or needs attention.
The Satellite archive also includes an RPM spec file. RPM users can build a binary package ready to install by running:
rpm -tb satellite-1.0.2.tar.gz
You will find the binary rpm under /usr/src/rpm/RPMS/i386 or /usr/src/redhat/RPMS/i386.
Reasons for Satellite
Public DNS services are often used to track clients with changing IP addresses, but DNS solutions suffer from several problems:
Failure
Public DNS servers regularly fail due to overloading and system administration problems.
No notification
There is no notification when a system goes online. Instead you must poll DNS regularly to see when a system comes online.
Latency
Updating can take from several minutes to several hours before the change is made public. On systems with small idle timeouts it is often impossible to find the current IP address via DNS.
No history
Public DNS services only keep track of the current address and dont record past times or changes in a central location.
Enhancements:
- Minor code improvements. -e no longer searches PATH.
- --with-port removed. Default now found from /etc/services.
- Documentation updates

settevion is a program that allows you to edit the channels in your Skymaster DXL 9400 Satellite Receiver.
This receiver was sold under the name Tevion FTA 203 by Aldi. Note that the current version does not allow writing radio channels into the receiver. Also note: This program makes use of undocumented behaviour. USE IT AT YOUR OWN RISK. There is no guarantee, even not against possible damage to your equipment. The program is free for personal, non-commercial use. Commercial use and copying (even at no cost) requires written permission. There are only german instructions provided, but Id not expect many problems for non-german speaking users since the programs dialog language is english.
Download settevion-x.x.x.tar.gz for Linux or settevion-win-x.x.x.zip for Windows. See the "Download" section below. For Linux, you must have Python installed (at least version 2.2) and Tkinter, which might be in a separate package. They are part of your distribution. Unpack the .tar.gz and do a "make install". The Windows version comes with its Python interpreter integrated into settevion.exe. Just unpack the zip file. For both versions, connect the receiver with a null modem cable and start settevion. Choose "Edit->Preferences" to select your serial device. Then choose "Receiver->Read data from receiver". This should be enough to make this run.
Enhancements:
- settevion.py: getDBPRINT: added code to read in SER data entry by entry since firmware version 2.12 doesnt dump the SER data base any more. satIO.read() changed to ignore asynchronous error messages ("trashlog") if they are one a line of their own. Warning message added if Python is called with -O and one of the debugging (-v) command line options is set. Version 1.4.1.

Berkley Snoop for Linux is a module which adds support for the Snoop protocol, a TCP-aware link layer protocol designed that can improve the performance of TCP over networks of wired and single-hop wireless links.
While TCP adapts well to network congestion, it does not adequately handle the vagaries of wireless media. In this thesis, we address these challenges in detail and design solutions to them. These solutions incorporate link-layer techniques as well as enhancements to TCP at the sender and receiver. The Snoop protocol is a TCP-aware link layer protocol designed to improve the performance of TCP over networks of wired and single-hop wireless links.
The implementation is for kernels of 2.6.x series. This software is intended to use on routers acting between big fat pipe(BFP) link and wireless link.
The problem: The wireless link is error prone by its nature and BFP links such as satellite one has very big round-trip time. When error occurs on wireless segment it causes in speed reduction because the TCP protocol on sending side treats this error as link congestion although the error was just a temporary link quality loss and the connection cannt recover its speed.
The fix: The module will cache TCP segmets passing to host on wireless segment until the ACK(nowledgmet) is received or timeout expired. In case of timeout the segment will be retransmitted again. And by the way the module will drop all DUP(licate) ACK(nowledgmets) caused by packet loss on wireless segment and prevent the reduction of speed of flow from the host beyond the satellite link. The module works now only with connections initiated from wireless hosts.
Enhancements:
- fixed issues with improper use of locks & memory allocation the memory allocates now with GFP_ATOMIC priority

IsaViz is a visual environment for browsing and authoring Resource Description Framework (RDF) models represented as graphs. Since version 2.0, IsaViz can render RDF graphs using GSS (Graph Stylesheets), a stylesheet language derived from CSS and SVG for styling RDF models represented as node-link diagrams. In addition to the Sesame 2.0 implementation of FSL, there is now a Sesame 1.2.2 implementation from Ryan Lee from project Simile.
Main features:
- a 2.5D user interface allowing smooth zooming and navigation in the graph
- creation and editing of graphs by drawing ellipses, boxes and arcs
- RDF/XML, Notation 3 and N-Triple import
- RDF/XML, Notation 3 and N-Triple export, but also SVG and PNG export

Dates project is a small, light-weight calendar that shares data with GNOME Evolution.

Dates is a small, light-weight calendar that shares data with GNOME Evolution. Dates features an innovative, unified, zooming view and is designed for use on hand-held devices, such as the Nokia 770 or the Sharp Zaurus series of PDAs.

GTKRawGallery software is an open source image viewer with camera raw files support written in Python and pygtk for Linux O.S.
Why should you try it? Because it has all you need from an image viewer: its very fast (tested with over than 10 Mb files) and light (less than 1900 code lines with a clean syntax for simple maintenance); finally, thanks to raw support, its the definitive solution to manage your photos!
