March 12 2019 System rescue, SpamAssassin, server hosting, curve plotting, plated Meet

Posted by John R Hudson ( 4 minute read )

John noted that Maplin is back as an online store. In response to Mike’s account of the problems he had had trying to install Arch on his computer, John suggested that he could delete all the existing partitions on the hard drive except the very first (very small) one by using System Rescue and then start the installation process afresh.

John managed to demonstrate System Rescue on his own computer by turning off UEFI, using Legacy to load it — though it would only work with the VESA drivers on his computer — and then reverting to UEFI. He said that the documentation is excellent but that they have their own way of creating a bootable USB which John had found you could get round by creating the CD version and then copying it to a USB.

February 12 2019 Journalism, CSS containers, Three funerals and a wedding, Docker containers, REMSCOPE, mysql_secure_installation Meet

Posted by John R Hudson ( 5 minute read )

The meeting began with a range of chit-chat. John H, commenting on a note about solution focused journalism, remarked that a very good journalist had told him that you always end a piece with something that left the reader thinking, not a neat solution. This led into a discussion of the principles of writing a good article and how, translated into radio, the principle that there should be a new point at least every 90 seconds was well worth following.
