Posted by John R Hudson ( 2 minute read )

Brian, John, David, Shi, Kriss and Yoghurt took part in a Jitsi meet.

Brian demonstrated the Paperwork which allows you to store documents in any format, including image formats, and then search (for) them using the inbuilt OCR which gives it an advantage over purely text based search engines.

March 18 2020 Meetings and Covid-19

Posted by John R Hudson ( 1 minute read )

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.

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.

Posted by John R Hudson ( 3 minute read )

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

Posted by John R Hudson ( 5 minute read )

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

Posted by John R Hudson ( 5 minute read )

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

Posted by John R Hudson ( 4 minute read )

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

Posted by John R Hudson ( 2 minute read )

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

Posted by John R Hudson ( 1 minute read )

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].
