I participated online in the conference „Functional Scala 2020“ in London. That it was in London had mostly one relevance, which was the time zone. There was no physical location and all talks were done online. An interesting idea was a virtual location. It consisted of rooms and we could move a dot representing ourselves …

For me it is much better to use an external mouse than the touchpad, which I sometimes touch accidentally. So, here is how to disable it with a short Perl-Script. A bash script with a bit of Perl would do the same, btw. #!/usr/bin/perl my $tp = `xinput list | egrep -i touch`; chomp $tp; …

I did talk about Clojure Art, which is fun and creates interesting visual results and helps getting into the phantastic language Clojure. But more than …
