The open-source section of the website got a lot of tweaking in the last few weeks. The recipient of the attention was the operating system subsection. That got a full reorganisation, with all the listings seeing new entries too. The desktop software also got a bit of attention, and other areas could get altered yet.
Recently, I have been having trouble with Nvidia drivers following a kernel update in Linux Mint (21.1 is the version that I am using). The kernel version has been rolled back from 5.19.x to 5.15.x, and I installed an old AMD graphics card as well.

Here are some North American online emporia for buying computers, their components or peripherals:
Here are boilerplate commands for banning and unbanning IP addresses using Fail2ban:
fail2ban-client set <JAIL> banip <IP>
fail2ban-client set <JAIL> unbanip <IP>
If you ever need to install Linux kernel headers on an openSUSE instance in order to install VirtualBox Guest Additions, the following command should be executed in order to do the needful:
sudo zypper in kernel-source
Here is a possible way of resetting the CSS definition for an HTML element, class or ID:
#reset-this-parent {

After seeing messages like "The authenticity of host 'hostname' can't be established" during ssh connections, I decided to investigate more and came up with the following solution:
sudo chown -v $USER ~/.ssh/known_hosts
My known_hosts file had gained root ownership so I could not write to it, so changing the ownership to that of my own user account sorted the problem. An alternative could be to change the group assignment using chgrp, and setting permissions using chmod, but what I did sufficed for my needs.
When I ran into trouble with accessing my own websites using my broadband, I found that the solution was to change DNS Lookup Service to what Google offers. This was done on the router side and the IP addresses used were 8.8.8.8 and 8.8.8.4.
Here's a way to convert DNG files to JPEG ones:
