It’s a good explanation why we have to use more cores instead of higher clock-speed in our modern computers and why Elixir is a very good choice to do ‘parallel programming’. Check it out at pragdave.me ….There is no direct URL I could provide to the vid....

It is a pain and a shame that we still have to suffer from lousy browser implementation. But we do. Lately, a big enterprise customer forces me to make a Phoenix.LiveView usable with Internet-Explorer 11 (because that’s the standard, they say) Ok, no comments about that.
