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

Retrieving Docker Image Sizes

There are two metrics that are important to consider when discussing the size of Docker images.

1. Compressed size - This is often referred to as the wire size. This affects how fast/slow images can be pulled from a registry. This impacts the first run experience on machines where images are not cached.
2. Uncompressed size - This is often referred to as the size on disk. This affects how much local storage is required to support your Docker workloads.

The example commands shown below will work on Windows, MacOS, and Linux.

How to Measure the Compressed Size

atomize

#  Add this to your .bashrc 
# Use it like: you@console_>$ _get https://website.org/file.txt
_get ()
{
  IFS=/ read proto z host query <<< "$1"
  exec 3< /dev/tcp/$host/80
  {
    echo GET /$query HTTP/1.1
    echo connection: close
    echo host: $host

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 2025-03-24: Commenting is disabled permanently. Previous comments are archived at web.archive.org. ]

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.

github_pubkey <- function(user){
  url <- sprintf("https://api.github.com/users/%s/keys", user)
  keys <- jsonlite::fromJSON(url)
  lapply(keys$key, openssl::read_pubkey)
}

# Get pubkey from Gabor
gabor <- github_pubkey('gaborcsardi')
pubkey <- gabor[[1]] #has 3 keys, use first one
