We met for the first time in two years at Bradford Community Broadcasting and also had our first hybrid meeting with Brian and John W online.

Brian said he had gone back to using a PBX as the interface for cordless ’phones and his mobile. The mobile connects via Bluetooth but the audio quality is poor.

Brian shared a problem he was having with tailscale which uses WireGuard; he had tried to transmit out to a network but it did not work. In Spain he can only watch the BBC on his computer but he can use Vivaldi to cast his desktop to the TV; in this way, he can log in to the BBC and then cast the programme to the TV.

November 9 2021 Review, Home Assistant, SMARTY, TV websites

Darren reported that his DVD drive door opens whenever the machine is returning from sleep; a couple of suggestions were made: that he checks the BIOS firmware and that he checks the boot order to see if the DVD is selected prior to the hard drive.

He is continuing to explore Picroft.

He showed a Bluetooth speaker he had acquired to amplify smartphone audio.

• draughts
• NIM (see this PDF)
• Jupyter notebooks, formerly IPython Notebooks, a web-based interactive environment for creating notebook documents; it is a bit like Zim in that you can import images, run programs, etc.
