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

libdispatch efficiency tips

The libdispatch is one of the most misused API due to the way it was presented to us when it was introduced and for many years after that, and due to the confusing documentation and API. This page is a compilation of important things to know if you're going to use this library. Many references are available at the end of this document pointing to comments from Apple's very own libdispatch maintainer (Pierre Habouzit).

My take-aways are:

• You should create very few, long-lived, well-defined queues. These queues should be seen as execution contexts in your program (gui, background work, ...) that benefit from executing in parallel. An important thing to note is that if these queues are all active at once, you will get as many threads running. In most apps, you probably do not need to create more than 3 or 4 queues.

• Go serial first, and as you find performance bottle necks, measure why, and if concurrency helps, apply with care, always validating under system pressure. Reuse

- IMPORTANT

For security, since this script injects CSS via AJAX, first fork the main slack night mode repo. The reason is explained here

UPDATE: The code has been modified to download the remote css to a local file and use ruby sass compiler to verify there is no malicious code in the remote css. This will error if the code has been modified to include anything malicious (i.e. script or img tags etc.) It's also been refactored to use the local file inside the js injection, it makes sure it's safe first in the very unlikely event the local file somehow differs from the remote css. The chances of this happening are remote, but this should suffice for safety.

Installation

• save this script wherever you keep your ruby scripts for example ~/lacostenycoder/scripts/ruby/
• change the URL in the remote_repo variable in ruby script to use YOUR repo. The rawgit.com file is crea

Following the tradition from last year, here's my complete list of all interesting features and updates I could find in Apple's OSes, SDKs and developer tools that were announced at this year's WWDC. This is based on the keynotes, the "What's New In ..." presentations and some others, Apple's release notes, and blog posts and tweets that I came across in the last few weeks.

If for some reason you haven't watched the talks yet, I really recommend watching at least the "State of the Union" and the "What's New In" intros for the platforms you're interested in. The unofficial WWDC Mac app is great way to download the videos and keep track of what you've already watched.

If you're interested, here are my WWDC 2015 notes (might be useful if you're planning to drop support for iOS 8 now and start using some iOS 9 APIs).

# The trick is to link the DeviceSupport folder from the beta to the stable version.
# sudo needed if you run the Mac App Store version. Always download the dmg instead... you'll thank me later :)

# Support iOS 15 devices (Xcode 13.0) with Xcode 12.5:
sudo ln -s /Applications/Xcode-beta.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/15.0 /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport

# Then restart Xcode and reconnect your devices. You will need to do that for every beta of future iOS versions

# (A similar approach works for older versions too, just change the version number after DeviceSupport)
