August 9 2022 Conda, alias Anaconda, VPN, HD TODAY

Posted by John R Hudson ( 3 minute read )

As BCB was closed, Bernard, David and John gathered at Wetherspoons where, by combining battery resources, they were able to hold an online meeting with Brian, Nick and John W.

Nick gave a presentation on Conda which was originally known as Anaconda and developed for use with Python/R but is now in more general scientific computing use. It is essentially a configuration manager; it does not replace anything else but allows you to manage different packages and versions of software in different environments without conflicts. It ensures reproducibility which is important for researchers when they wish to share findings.

Brian had been able to set up Asterisk and knew that he could make outgoing calls. He demonstrated that his mobile showed up under ‘mobile shell devices,’ he was successful in calling Nick’s ’phone and the quality was all right at Brian’s end. However, when Nick tried to call him, he got Brian’s mobile voicemail. John mentioned that, in setting up some new cordless ’phones at home, he had found his provider began its answerphone message after four rings. He suggested the problem might be his provider’s settings.

It has been great creating the shows with the other Stuffers (heh) who have become some of my most favouritest peeps.

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 asked a question about searching for someone when you have their last address but are not sure whether they are still there which generated a number of suggestions, none of which appeared conclusive.

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.
