In my persona as an Associate Lecturer of the Open University, I promised some brief notes on Open Source software to help a colleague who’s leading a Staff Development workshop in a couple of weeks’ time.
Educational providers always need to find workable inexpensive software to provision their students. Around 1990 I taught the first Open University course which took ICT facilities to the students in their homes, rather than requiring them to book time on terminals hosted by friendly local institutions. The DT200 course existed in the days of DOS, but it used an early on-screen word processor (FirstWordPlus on the GEM GUI), a cut-down version of the Lotus 1-2-3 spreadsheet, and the CoSy conferencing system. The configuration was an Amstrad 640 with two 5.25 inch floppy drives and no hard disk. Oh, and the mouse port was on the left hand side which is why, more than 20 years later, I still use my mouse left handed.
I promised some notes, as I said. And I thought I’d share them more widely. I use Open Source software quite freely but nothing startling. I also use other freeware and a handful of niche purchased products, such as Graphic Converter for the relatively limited image manipulation I need to do.
My main OU course now is the ICT foundation course which introduces students to a range of practical ICT tools as well as the social and global context in which the technologies operate. It uses Audacity for audio recording, which I’d been using for some time already for creating podcasts for students on another course. It uses FreeMind for mind maps. Alongside this it uses tools like Picasa for image manipulation which is free (from Google) but of course isn’t Open Source.
I use a Mac but run it sometimes as a Windows machine using BootCamp. On Windows I don’t maintain a Microsoft Office licence so I use Open Office. While there are some compatibility issues with on-screen presentation I haven’t hit any significant problems. I know there are some, but they haven’t affected anything I’ve needed to do. I use the VLC media player on Mac for Windows Media Player formats, since Microsoft no longer make a player for Mac.
The Firefox browser and other elements of the Mozilla family are of course Open Sourced and Firefox is my browser of choice. I use the internal web server on my Mac which is a version of Apache.
For application development I use Cincom Smalltalk which is a full object-oriented environment and although it’s commercially owned it’s developed by its OS community. I learned Smalltalk, also 20 years ago, when working on a collaborative academic-industry research project and I still love it.
Working in industry, as I did until recently, I encountered a lot of suspicion about Open Source. More recently I think it’s abated somewhat but it’s still there.
The debate around OS in the commercial IT sector focusses on accountability – not knowing who is accountable for quality or who can be sued (to put it bluntly) for any real problems. It’s difficult for procurement-minded professionals to accept that a community of interest is likely to have higher quality standards and to identify and fix problems more quickly than a major for-profit software supplier.
This attitude has softened over the past several years, not least because some software (such as Apache and Linux) has become widely used in the enterprise. To my reading there are (at least) two reasons. Cost (obviously) but also licensing.
It’s a lot easier to promote a web service when you don’t have to license according to the number of users. Quality has become a given for the most widely used products. Security can be easier to assure and handle when there can be access to source code. And acquiring OS software through a distributor does offer some assurance of quality. There have been some high profile espousals of OS software, such as Linux or Open Office in government departments which are supremely cost-conscious, but these haven’t had an enormous impact in the wider commercial marketplace.
What is, I think, true is that as more specialised niche requirements have been accepted within the enterprise, there’s a recognition that either open source or niche (= small startup) providers may be the only route to a solution. Someone, somewhere, has created an open source community around your need.
There are various definitions of what constitutes Open Source. By one definition, a specification is “Open” if it is published, so that it can be used by other platforms – as other word processing software can create documents in Microsoft’s format. Conversely, the Open Document Format was defined through an open process: but isn’t yet accepted as the leading standard for interoperability. This is the open process I learned about through by participation in the Object Management Group’s work. Building consensus and reconciling different viewpoints, including those of commercial developers, takes time: but there is often a strong academic foundation, and academic rigour often sustains a longer-lasting and more effective standard. Or, again, there is development through an open community which brings many minds to bear on problems; which converges on useful solutions; but which can become self-perpetuating so that the vision does not always grow or, where necessary, change.
• Sourceforge: one of the strongest groups of Open source communities
• Sourceforge is host to Audacity and to FreeMind
• Linux (of course)
• Apache (the Apache Software Foundation) also hosts Open Office
• Mozilla for Firefox, Thunderbird and more
• Smalltalk (see this page for versions)
• VLC media player
• Graphic Converter from Lemkesoft
• Picasa from Google
• Gem Desktop
