Section 25.


"The Internet is not just one thing, it’s a collection of things - of numerous communications networks that all speak the same digital language."

Jim Clark - founder of Netscape.

25. Some Linux applications.

For almost every application we can think of there is a Open Source alternative. For many major applications and protocols the UNIX / Linux incarnation came first. Where an MS Windows package is absolutely required and there is no Linux version available, there is WINE.

25.1. Wine Is Not an Emulator.

Wine uses re-implementations of Windows DLLs to provide a compatibility layer that allows Windows applications to run on Linux. Wine provides more extensive backward compatibility for old windows applications (from Windows 3.0) than the real thing in compatibility mode.

25.2. Exercise.

Download and install Wine.

Download, install and test a free windows application to run under Wine.

25.3. LibreOffice.

LibreOffice split from OpenOffice in 2010 when many in the Open Source community became frustrated with the lack of clear open source development plan by its new owners Oracle.

LibreOffice is an integrated office suite that is available for Windows, Mac and UNIX / Linux platforms. LibreOffice can read and write to files in a large range of formats.

25.4. Exercise

Download, install and try LibreOffice.

25.5. Issue, bug and ticket trackers.

There are a large number of open source issue trackers available. Several of them were developed alongside other software initiatives.

Bugzilla is perhaps the best known and is used and maintained by Mozilla (Firefox), Apache and the Linux kernel development team.

My favourite in recent years has been the award winning Roundup.

Roundup can be used on the web, by email and on the command line. It is relatively easy to install and configure. Extensions to the basic package are available and it is relatively easy to enhance with a very little understanding of PHP.

25.6. Exercises.

Use to research open source applications for bug tracking.

Install and configure Roundup on your Linux host.
