Ubuntu VM on macOS with QEMU

For work I have an Intel Core i5 MacBook. With the Docker Desktop license changes I looked into minikube and Multipass but both failed when I got on our VPN with Cisco AnyConnect due to bridged networking in hyperkit (see links at bottom).

I realized I would be happy SSHing into a local Linux VM but passed on VirtualBox to avoid depending on legacy system extensions. I landed on libvirt for the VM, then realized I could remove libvirt from the equation to finally end up at this quick, simple setup for an Ubuntu VM on macOS with QEMU.

First, install QEMU (see https://wiki.qemu.org/Hosts/Mac for other o

I'm not kidding. Road-level trolley tracks and cyclists simply do not mix. I've been in accidents due to tracks in Philadelphia and San Francisco -- the two cities I've lived in with tracks in the streets. Nearly every cyclist I know in Philadelphia has been in at least one minor accident involving tracks, and several have real horror stories. A friend broke several bones in her face due to a slip on the tracks just weeks ago.

But you're right. I may be overestimating in my "thousands of injuries" claim. Unfortunately, we don't have solid data around this issue to reason from. No one keeps track of the number of bicycle accidents caused by trolley tracks, and cycling accidents in general are sorely under-reported. According to the 2012 PennDot Crash Facts & Statistics [1], there were 1,369 total bicycle accidents in Pennsylvania. Considering the estimated 36
