We normally meet (but see below) every second Tuesday of the month for talks and demonstrations from 7:00pm onwards at BCB Radio.
Why not come along to a meeting?
Some of us also create IT Stuff for BCB Radio (106.6 FM) every four weeks on Thursday, 6:00pm-6:30pm. Repeated the next day on Friday at 1:30pm-2:00pm.
Brian showed a device he had which measures particulates, in particular the PM2.5 particulates which are particularly dangerous. They had recently experienced sand being blown onshore from the Sahara but there had been none of usual cases of people being affected by the sand particles because people were wearing masks because of the pandemic. Bernard said that he had once experienced sand particles on snow when skiing; when snow later fell on the sand, it turned orange.
Brian finally managed to sort out John’s audio by clarifying that in PulseAudio the settings in the Playback and Recording tabs should be 100% and any volume adjustments made in the Output and Input tabs.
As there were still problems with the sound on John’s new laptop, we started with a discussion of sound on chromium, whether it might worth trying Firefox, which did not recognise John’s external microphone, or whether it might be worth trying another microphone, without coming to any satisfactory conclusion.
Brian, John W, Bernard, David, Darren and John H joined the meeting this month. Brian began by describing some of the neighbour trouble he was having before
Bernard demonstrated how the content of the four projects contained in LXD containers on the Webparametrics website
As no-one had prepared anything specific for the meeting, the conversation wandered over a wide range of computing and non-computing topics.
Brian has swapped from Digital Ocean to Amazon because he only needs a web server and not a website but he was puzzled by the output of
free -m which suggested that he had very little free memory. David explained that the Linux kernel uses whatever memory there is for cache and so will reclaim memory from cache if it needs more than the free memory available.
Brian shared the problems he was having connecting over
ssh behind carrier grade NAT. A number of possible solutions were discussed including using wireguard or
socat or following the SSH Port Forwarding Example and the problem was eventually solved.
David S is still looking for a decent Android text editor. This query led on to a discussion of Android Firefox problems. Bernard, Darren, Brian, David, John and, later, Nick joined the discussion.
Brian shared a number of problems he was having configuring a VPN with the Microtik router OS; the only suggestion people could make was to use Wireguard instead for what he wants. Brian also mentioned that he had had a look at Boxee Smart DNS as a possible way forward.
Unfortunately, there were problems with the audio in particular this time which meant that several people who joined us left the meeting. For those who remained
Darren demonstrated a simplified version of
cat(1), written in Dlang. It had only one loop, two variables, and three function calls to the D standard library.
Bernard demonstrated using Python virtual environments.
