Editorial Viewpoint
Shutting down our old website
From around 2000 to 2012, our website was run by
a third party and not under our direct control. When
I started working at Silicon Chip, it was apparent
that we needed to build our own website for various
reasons. For example, our subscription system was
completely separate from the website, so there was
no good way for people to renew their subscriptions
online (or change their address etc).
There were a lot of other reasons to take control, such as being able to
sell items like PCBs from the website, which is now a critical service that
we provide, along with other parts. It would also give us better control over
how our articles were presented online. It just made so much more sense to
handle it ourselves.
When we set up the new website, we had to decide what to do about people who had paid for access to articles or magazine issues through the old
one. We realised that we had to provide continuity, so everyone who had
access to a magazine through the old method was given perpetual access to
the same issue on the new website.
We also kept the old website going as-is to provide the best transition possible for our readers, allowing them to decide when they wanted to switch over.
But as time goes on, there seems to be less point in keeping that old website
(http://archive.siliconchip.com.au) going. By early 2020, we finished adding
all the back issues on our current website, back to the very first issue (November 1987). That’s all the content that was on our old website, and much more.
Our main website – www.siliconchip.com.au (or www.siliconchip.au if you
prefer a slightly shorter URL), does everything the old site did and so much
more. So I think the time is approaching to shut the archive server down.
With PDFs now being available for the latest issues to subscribers, and even
older issues for those who’ve purchased the PDFs on USB collection (or paid
for separate back issues), there is even less reason to keep the archive site up.
The presentation of articles in our PDFs is so much better than on the
archive website, where the articles were converted to HTML format and diagrams were rasterised, often making them blurry or pixelated.
So I am writing this to give anyone who objects to that an opportunity to
contact us and explain why they think we should keep the archive server
up. As the saying goes, “speak now or forever hold your peace”.
If you’re wondering why I want to shut it down, part of the reason is that
we didn’t develop any of the code, and it is now on a very old platform that
sees few updates. I’m concerned about the security implications of keeping
such old software running. It is isolated from the rest of our infrastructure,
but a breach could still reveal some customer information such as names
and e-mail addresses.
There are also costs associated with keeping it going, including some of
our time and hosting expenses that I would rather spend on our current website and producing new content.
I hope that, by now, all our readers have switched over to using the new
website. If not, please give it a go as we believe it is a significant improvement over the old one.
Unless we are given good reasons to keep it going, we plan to shut the
archive site down by the end of July 2022.
