<h3 id="network">The Expo Laptops: Crowley's Friends, Aziraphale and Anathema</h3>
<p>The <i>expo laptop</i> is called "Crowley". Crowley was rather too ill to be useful during the 2022 expo (being left in the potato hut for 3 years was not a healthy experience) but is now feeling much better... apart from the WiFi which needs a software driver update, but as Crowley is connected to the ethernet cable this is not vital.

<p>In 2023 we had another general-use laptop "Aziraphale" (it was also on expo in 2019). This is not connected by any cabling and just uses WiFi. Like Crowley it is running Debian and has the same set of software installed
(survex/aven, tunnelx, therion, git etc.) and you login to it using the username "expo" and the usual cavey:beery password. It has the identical[Cinnamon/Debian] configuration and survey software installed as Crowley. It is a big, heavy R61 14-inch Thinkpad on loan from Michael Sargent. (Note that Aziraphale's SD code slot doesn't work).

<li>"Barbie" is a pink netbook dating from 2014 which was intended as a replacement to the blue Acer Aspire but which is currently a general use laptop. It is an "HP Stream 11 Notebook", has only 2GB of memory, a 2.16GHz Celeron N2840, 32GB eMMC "drive" and is consequently a bit slow - it is donated by Philip Sargent. We have a 12V power supply for this, and it is small and light, so could be relocated to StoneBridge topcamp if that seems to be useful.
<li>"Anathema" is currently running Xubuntu/xfce (not Debian/Cinnamon like the others). As well as a recent solid-state disc and wifi it has an ethernet socket and (unsually) a working battery of 2 hours, pretty good for a 2011 machine. This is part of the Waddington bequest to expo (actually Michael Waddington's old gaming alienware laptop). It is actually configured to run troggle software locally, should that be required. It weighs 2kg and we don't have a 12V power supply for it, so it will live at base camp.
<li>"Pulsifer" is also running Xubuntu/xfce. It has a recent solid-state disc, wifi, ethernet socket and (unsually) a working battery of about 1 hour. It is configured to run troggle software locally (but not as user 'expo'). It is old and heavy but we do have a 12V supply for it. Installed in potato hut 16th July 2025.
