March 18 2020 Meetings and Covid-19

The absence of any reports on the meetings in February 2020 and March 2020 did not mean that the meetings did not go ahead but that those attending pursued individual projects and there were no presentations.

The Covid-19 pandemic means that we are unlikely to meet face to face in the near future but we are exploring the possibilities of virtual meetings.

Keep in touch through our mailing list.

January 14 2020 PineTime, watch, computer games and 3D printing Meet

Mike had had problems applying a patch to dhcpcd and so David S talked him through the process while the rest of us got on with the meeting.

December 10 2019 Inkscape, xfig and Scribus Meet

David had been demonstrating shaders in GIMP and Mike sharing his experiences with broadband and servers when John arrived rather late with a demonstration of using free and open source software to do something which had originally been done in proprietary software.

November 12 2019 Thought Bubble, Astronomy Project and IT Management Meet

After an exchange of various news items, Bernard mentioned his visit to the Thought Bubble Festival in Harrogate the previous week where a wide range of novel and comic book authors had appeared; Bernard had attended a panel on web comics which had looked at the artistic issues and the technical ones — specifically that web comics do not pay, though it is possible to raise money through patrons or kickstarter funding.

October 08 2019 DNS, Freedombone, Minetest, CSS containers and Mastodon Meet

Mike raised a problem he was having with DNS and Rob, joining us once again after a long absence, explained that the big players and the Content delivery networks were effectively operating a new version of DNS. The only answer was to get a domain hosted by one of the majors like GoDaddy. He went on to say that, notwithstanding the objections from state actors to encryption, end to end encryption would become the default with IPv6 and IoT because it was the only way to make IoT viable. Whatever happens, it will involve changes to hardware, firmware and the Linux kernel. Interestingly, the US Navy which uses Windows is using Linux containers for security.

September 10 2019 Postfix, Raspberry Pi, Chromebooks, Wuthering Bytes and Gramps Meet

Mike had encountered a problem with Postfix in that it didn’t start after it had been stopped for a reboot. A quick search revealed that a similar problem had been around in 2016 in both the RedHat and Debian versions of Postfix when it had been traced to a file being left in the wrong place. After discussion, it was suggested that Mike write a script which periodically checked that Postfix was running and then started it if it was not.

August 13 2019 Magic-Wormhole, Yandex Disk, vole.wtf quiz, backups and ssltest Meet

Brian had hoped to demonstrate Magic-Wormhole which allows command line communication between two computers where the sender enters:

wormhole send <filename>

which generates a code which the receiver can use when prompted by

wormhole receive

to receive the file. However, Internet access was down.

July 09 2019 Infra-red photography and WordPress Meet

Bernard showed us the results of his infra-red photography kit, powered by his Raspberry Pi. We saw, after some image enhancement in VLC media player, a hedgehog wandering past his hide, a crate in his garden [there was some dispute later as to whether the creature was a hedgehog or a rat].

June 11 2019 darktable and Spreadsheets Meet

Mike left the explanation of how to configure a server to allow a single IP address to serve four domains, each configured as a subdomain on the server, until next month when Brian will be back and gave a presentation on darktable. He illustrated a variety of effects, how you can organise the right hand pane to reflect your personal workflow and how easy it is to access and work with the history feature.

May 14 2019 Sub-domains, LXD and Jekyll Meet

Mike tried to explain to Brian how he configured his server to allow a single IP address to serve four domains, each configured as a subdomain on his server. It was suggested that Mike prepare a piece on this for a later meeting.

It was noted in passing that the Windows Subsystem for Linux is getting a Linux kernel.
