We normally meet every second Tuesday of the month for talks and demonstrations from 7:00pm onwards at BCB Radio in February, May, August and November and online in other months.
Why not come along to a meeting?
John said he had been at a hybrid meeting with Tim Berners-Lee the previous day when Tim Berners-Lee had explained what he meant by Web 1, Web 2 and Web 3. Web 1 was the era of static websites based on Netscape, though the original design of the web had included the possibility of editing it. Web 2 was the era of server based websites developed by programmers though his intention had been that the web should be WYSIWYG. The problem with server based websites was that the data was held on a server which was a long way from the user and had to be retrieved every time and which was not under the control of the user. Web 3 is about giving back to users control of their data by creating decentralised storage over which the user has control; so, for example, you would control your health records and give permission to your doctor to use them. Web 3 is being developed by the Solid Project which he invited developers to join.
Brian shared the collaborative tool Figma which Adobe have acquired; it is aimed at improving the user interface and user experience.
Brian said that, though he had used Node_RED to control the automation of thermostats (see November 2021 BradLUG meeting), this had proved unreliable because Node-RED kept rebooting at random times; he had discovered that this was probably linked to unreliable dependencies.
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.
David showed how far he had got using his 3D printer to create the ESP32-Cam Pan&Tilt as described in the Random Nerd Tutorials which he had first mentioned at the January meeting. He demonstrated the USB plug he had made working as intended.
Our second attempt at a hybrid meeting was less successful than our first with problems with both video and audio.
It has been great creating the shows with the other Stuffers (heh) who have become some of my most favouritest peeps.
Firstly, wow — we managed seven years worth of consistent (lol) unadulterated tech comedy opinion-based content, about 87 or more episodes in total.
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.
He had discovered that the Raspberry Pi 2 is the minimum on which you can use NordVPN with which he is using the Raspberry Pi as a gateway.
