I have found numerous
open-source
software programs to be reliable and useful in my consulting
business. Some of them are:
Mozilla - This is the open-source
basis for what Netscape has become. It seems to be evolving and
improving quickly.
Openoffice.org - This is the
open-source basis on which Sun's StarOffice is built. It is a
full-featured office suite which can import and export Word, Excel, and
PowerPoint compatible files. I have found it to be useable but a
bit buggy.
TightVNC - This is an enhanced version of
VNC, or Virtual Network Computing, which is a cross-platform program
that allows one computer to control another over the network.
OpenG - The LabVIEW community has
its
own open-source effort under way. OpenG hosts numerous LabVIEW
development projects available for anyone to use.
Another program I have found useful is
IrfanView, a versatile graphics
viewing and editing program. Although IrfanView is not
open-source, it is free for personal use and requires a very modest fee
for commercial use.
