The launch of Raspberry Pi 4 is significant in its own right, especially as its improved specs make it a cheap server (60 Euros). Cheap servers play a role in a whole host of distributed applications, like running your own cloud, calendar, smart home appliances, internet of things hub, machine learning efforts, and federated social media. I look forward to getting my hands on a Pi4.
To show off its specs, the Raspberry Pi 4 launch website, attracting tens of millions of visitors over a few days, is being run on a cluster of 18 Raspberry Pi 4’s. (found via Jason Cosper, @email@example.com)
