    I’ve signed up to ride Bike MS 2020 for a 3rd year June 27-28. They haven’t published the route yet, but it’s usually a 100 mile route from Westminster to Fort Collins, then around 50 miles back the next day. I’m still unsure if it’ll be cancelled/postponed due to Covid19. But even if it doesn’t…

The following tutorial will walk…

    Ubuntu 14.04 originally shipped with a 4.4-based kernel, which didn’t yet support booting as a KVM guest on GICv3 systems. This meant you could only boot trusty instances on GICv2-based hosts. However, thanks to our Foundations team, Ubuntu 14.04 (‘trusty’)/arm64 images have switched to using the Ubuntu HWE kernel. This means you can now run Ubuntu 14.04…
