<p>We recorded this on Saturday May 20<sup>th</sup> 2023. We met in
person again, and as before first visited the pub called <em>The
Steading</em> where we had lunch. Then we adjourned to Dave’s Citroen
car (<em>Studio C</em>) in the car park, and recorded a chat.</p>
<p>The region where we met is close to a village called
<em>Hillend</em>, which led to the show title.</p>

<ul>
<li>ChatGPT:
<ul>
<li>MrX did two shows in May using ChatGPT. He has used it more than
Dave has.</li>
<li>MrX has an iPhone and can use ChatGPT from it. He uses it as a
source of information when out and about. For instance, to find out
about the history of <a
href="https://en.wikipedia.org/wiki/Musselburgh">Musselburgh</a>
Harbour.</li>
<li>MrX has also used ChatGPT to write experimental Python scripts.</li>
<li>There is a <a
href="https://www.ted.com/talks/greg_brockman_the_inside_story_of_chatgpt_s_astonishing_potential/c?language=en">TED
talk by Greg Brockman</a>, the inventor of ChatGPT.</li>
<li>Discussion of the <a href="https://callannie.ai/"><em>Call
Annie</em></a> app</li>
<li><a href="https://en.wikipedia.org/wiki/ELIZA">ELIZA</a> the program
that was written in the 1960s and simulated conversation well enough to
convince people.</li>
</ul></li>
</ul>
<ul>
<li>Audacity/Tenacity audio editors:
<ul>
<li>Web sites: <a href="https://support.audacityteam.org/">Audacity</a>
and <a href="https://tenacityaudio.org/">Tenacity</a>.</li>
<li><a
href="https://en.wikipedia.org/wiki/Audacity_(audio_editor)">Audacity
Wikipedia page</a></li>
<li>MrX and Dave have both used Audacity for several years.</li>
<li>Audacity was forked after it was taken over by <a
href="https://mu.se/">Muse Group</a>, and Tenacity was developed.
However, it doesn’t seem that there have been any releases on Tenacity
to date.</li>
<li>The most recent versions of Audacity have contained changes - in
particular the way the audio project is stored has changed. Instead of a
directory filled with various files there is now a single project file
with the extension <code>.aup3</code> which is a SQLite database. This
was changed in March 2021 for Version 3.0.
<ul>
<li>Previously Audacity stored the project as a file called
<code>&lt;project&gt;.aup</code> and a directory called
<code>&lt;project&gt;_data/</code> containing sub-directories and
files.</li>
</ul></li>
<li>MrX reports changes in the way multiple tracks are handled. Dave
finds that the horizontal scrollbar has disappeared (which seems to be a
bug).</li>
</ul></li>

<li>Dr John Campbell:
<ul>
<li><a
href="https://www.youtube.com/channel/UCF9IOB2TExg3QIBupFtBDxg">YouTube
channel</a></li>
<li>During the COVID-19 epidemic the channel contained a lot of
information about the SARS-CoV-2 virus, vaccines, disease, treatments,
etc, which seemed to be helpful and well researched.</li>
<li>At one point there was a lot of talk about Ivermectin as a drug that
could help with the disease, but although this received no support from
scientific research, it seemed to be receiving more and more exposure on
the channel.</li>
<li>From then on the quality of the content on the channel seemed to
deteriorate, and it no longer seems trustworthy.</li>
<li>Other sources have been critical, including <a

the Funk with Dr Wilson</em></a></li>
</ul></li>
</ul>
<ul>
<li>The Doctor Who Exhibition:
<ul>
<li>Dave met with Andrew Conway and Andrew’s friend, and all went to the
exhibition held at the National Museum of Scotland.</li>
<li>The exhibition contained a lot of Doctor Who memorabilia, including
some original props.</li>
<li>MrX and the group that went to the exhibition have all watched
Doctor Who over the years. All have lost interest at some point but then
resumed, particularly after the show was restarted in 2005 with
Christopher Eccleston and Billie Piper.</li>
<li>Discussion about the <a
href="https://en.wikipedia.org/wiki/BBC_Radiophonic_Workshop">BBC
Radiophonic Workshop</a> where the Doctor Who sound effects were made as
well as the signature tune. Also the <a

<li>The Swedish band <a
href="https://en.wikipedia.org/wiki/Wintergatan"><em>Wintergatan</em></a>

href="https://en.wikipedia.org/wiki/Martin_Molin">Martin Molin</a>, a
band member is responsible for some of them. He did a series on YouTube
about mechanical instruments: <a
href="https://www.youtube.com/playlist?list=PLLLYkE3G1HEBO1slIc1RRfcfSsGyv2oMu"><em>Music
