Windows 11 on MacBook M1 (ARM)

Steps I went through to install a Windows Insider Preview VHDX on a Macbook Pro using UTM. I needed Windows because I was developing an app to submit to the Microsoft Store. With the following setup I was able to develop an electron-based app and submit it to the Microsoft Store.

1. Download the VHDX from Windows Insider Previews. You need to register for the Insider Program and sign in.
   • under Select edition select the Canary channel and press Confirm
   • select language and confirm
   • press Download
2. Open UTM and press + to create a new virtual machine
   • Virtualize

• Windows

sub-mod

Here is an example of doing it on Fedora.

1. Go to https://access.redhat.com/management/systems/
2. Click on your system which has subscription attached.
3. Download the subscription certificate to your non-RHEL host(laptop).
4. Extract all files and then only place the *.pem file to e.g. ${ENT_DIR}/${ID}.pem

This snippet shows how you could use later to create an API that can be called on a background thread, to perform an arbitrary task on the main R thread, and return the result to the background thread. The background thread blocks until the result is returned from the main R thread.

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

[ Update 2020-05-31: I won't be maintaining this page or responding to comments anymore (except for perhaps a few exceptional occasions). ]

---

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
