Jake Waas will present a straightforward blockchain consisting of XML, conveniently viewable with a web browser. The miner / archival node is implemented in steel bank common lisp. Several important TODOs include the having of more than one node, defining a smart contract XML and using GPG signing. We can see the basic structure of a blockchain, and consider how and why they are useful. Hopefully he can learn something to add to his blockchain too!

Ian Stewart will talk about his experience of performing an online upgrade of Ubuntu 18.04.5 to 20.04.1.
