Brian demonstrated Glances, a cross-platform system monitoring tool written in Python, running in
tmux on his server.
He then said that he had installed Nextcloud using a server running on a Raspberry Pi. This is relatively easy on a Raspberry Pi 2, less so on a Raspberry Pi 3. It involves downloading the server image onto a desktop computer, copying it onto an SD card, putting this in the Raspberry Pi, booting it and then updating the image.
Darrenshared his experiences at the June Leeds Code Dojo meeting when the programming challenge was to write a parser for Befunge whose code is written on a two dimensional grid and uses Reverse Polish Notation. Befunge was originally written to be as hard to compile as possible though compilers do exist for it. He showed the parser he had written in D.
Brian showed us his new laptop from PCSpecialist running Linux Mint with Cairo Dock and recalled that he had been looking for a replacement for Tomboy because it does not synchronise well and cannot show anything other than text. He had found Joplin which uses Markdown and, following a recent request, now has a search within notes feature.
Oliver shared his recent experiences of the i3 tiling window manager. It is very easy to flip between tiles and between tiles in different workspaces which makes it easy to move between different terminals. i3 has a lot of add-ons but mostly they add bling.
Darren brought a problem he had had with some wi-fi headphones but, after various attempts to find a solution, we concluded that there was a hardware compatibility problem.
John thanked members for their contributions at the previous meeting to the GDPR presentation which had been well-accepted by non-geeks. He went on to highlight a number of changes to HTML and CSS. Ostensibly there had been very few changes to HTML — such as the removal of the <keygen> and <menuitem> elements — but the apparently superfluous <main> element which had been added four or five years earlier had been revealed as the foundation for some far reaching developments.
John shared a presentation he was developing on GDPR for small voluntary organisations. David S commented that the test for organisations would be ‘have you made a bona fide attempt to meet the regulations?’ He also commented on the three different uses of ‘loss’:
Brian described how he had reflashed his smartphone and his tablet. With the demise of CyanogenMod, LineageOS has taken taken over this space. First go to the Wiki and find the codename for your device; then click on that for the instructions for your device. Note that these are overcomplicated and many steps can be ignored.
