Parkdale Church of Christ - seeking God, learning to live
the Gospel together
|












 |
Parkdale Church of Christ uses computers extensively - this is hardly
surprising since our minister came to us from a long career in the computer
industry! However, most of the computers are old, recycled, or made up from bits
of others, and all except one were donated. Consequently, we needed to break out
of the classic spiral of needing a new computer every time a new operating
system version came out.
This is how we did it:
- We use free software, and especially open
source
software, whenever possible.
Software of this kind is often similar to commercial software, but lacks
some of the more sophisticated features. Since most users don't know how to
use these features, this hardly matters. Sometimes the user interface is not
so good, and so the software is harder to use at first; but this is soon
overcome with practice. Sometimes the open source software is better than
the commercial software, being free of marketing-based limitations or an
unlikely target for malware.
The operating system on most of
the computers is not Windows but Ubuntu, or a variant of
it for educational purposes, Edubuntu.
These are based on GNU/Linux,
and are available free. There are many rival GNU/Linux systems
available, but we use Ubuntu primarily because of its community ethos of
sharing and respect for the other, which corresponds to Jesus' teaching of
love for our neighbour as second only to our love for God; and secondly
because it is not so different from Windows as to be unrecognisable to
Windows users.
Where we do use commercial software, there must be a good reason - such as a
large old printer/photocopier whose manufacturer has not made a driver
available for non-commercial systems. We are pragmatic about this, not religious! Next time we buy a
copier, we will choose a different manufacturer.
- Similarly, we use OpenOffice for
all word processing (including our weekly newsletter and overheads for use
during services), spreadsheets, and
simple databases. This means that members who produce documents for the
Church at home do not have to purchase expensive software, since there is a
version of OpenOffice for Windows too.
- We don't buy hardware that is more powerful than we need. The 8-page
church newsletter, for example, is primarily created using a highly portable
Netbook attached to a full-sized keyboard and monitor, and the same system
happily copes with a 58-page tertiary-level research essay, complete with
footnotes and diagrams. The industry likes to promote these devices only for
very basic needs, and intends them to be used mainly with online
applications through the Internet, but the reality is they are just as
powerful as the normal laptops of three or four years ago, and can be
found with large disk drives. Ubuntu is
also used on the Netbook. It replaced a five-year-old Tablet
PC that originally cost six times as much as the Netbook!
- We have a total of eight old Pentium 3 computers that are used for
teaching computer classes. With commercial software they would
be so slow as to be virtually unusable. We run these as network-booting terminals to a more
powerful, but still old, terminal server (it's got a Pentium 4 cpu, wow!) that
runs Ubuntu as its operating system, with additions to support use as a
terminal server. This means we are
immune to most viruses and malware, and only one machine needs to be maintained instead of
eight. The
old slow terminals still run fast as far as the user is concerned, because
the server does all the work. The user sessions are tailored locally to
suit older people as well as children. Using free software for this project
has saved us thousands of dollars in licensing costs!
- Our services are recorded using Audacity
on Ubuntu, which allows us to produce recordings in the free OGG format, and
to burn audio CDs of our services for those who were unable to attend.
- We use a wireless network to link the main computers together. The terminals are linked to the terminal server using standard cabling.
- The office computer provides internet content filtering for all the others
to avoid embarrassment!
We have been asked why we didn't simply make use of generous charity pricing
on commercial software. Here are a few reasons:
- A practical reason: charity pricing wouldn't apply to software
used by our members at home for newsletter production, for example.
- An ethical reason: charity pricing appears to be the commercial
software producers being generous, but in reality it protects their
market share - and at the same time undermines the viability of
alternative systems. This is anti-competitive, and strengthens the
power of the few companies which control the computer
industry.
- Another practical reason: charity pricing requires record-keeping
so that the right number of licences are bought, and upgraded from
time to time. Installation keys and online activation are required
to link these licences to particular machines. We do none of this!
Contrary to the trend, this website is still produced using old commercial
software! That's just laziness...
