tmcw

So, as I mentioned last time, I have two fundamental goals with dat that are not addressed by simply running dat share.

• Uptime: making sure that the site is seeded even if my local laptop is closed, eaten by a bear, or disconnected from the internet
• Resilience: ensuring that there's a way to restart my website if the original seeding computer is lost. I try to make everything on my primary work/personal computer work in such a way that I can recover it all, easily, onto a new machine if I need to

To break these down a bit more, uptime is a combination of two things:

• Ensuring that there are seeders
• Ensuring that those seeders are seeding, and they're up-to-date

Ford Fusion

Overview and Rationale

Ford Fusion was an overhaul of Urbit's over-the-air upgrade process and a rewrite of its build system. The new update system corrects a few long-standing bugs with the previous one, and the new build system is simpler, smaller (by around 5,000 lines), and easier to manage.

Since deployment of Ford Fusion to the livenet in late June, over-the-air updates (OTAs) have been much smoother. Before Ford Fusion, it was common for an OTA to take several hours, use too much memory, and leave ships in inconsistent states. After Ford Fusion, multiple OTAs have been pushed out, including kernelspace changes, and most users didn't even notice.

Urbit has always been able to update itself OTA, but this process has often been rocky. Updating an operating system kernel on-the-fly is a difficult problem in general, like performing heart replacement surgery on yourself while running a marathon. Code that allows Linux to update its kernel in this way became a startup called Ksplice, won
