Using Rosetta2 in Docker on ArchLinux arm64 - Apple M1

1. Start vm with tart

tart run archlinux --no-graphics --dir=shared:~/Sources --rosetta=ROSETTA

2. mount rosetta to Linux

sudo mkdir -p /mnt/rosetta
sudo mount -t virtiofs ROSETTA /mnt/rosetta

Linux Desktop on Apple Silicon in Practice

I bought M1 MacBook Air. It is the fastest computer I have, and I have been a GNOME/GNU/Linux user for long time. It is obvious conclusion that I need practical Linux desktop environment on Apple Silicon.

Fortunately, Linux already works on Apple Silicon/M1. But how practical is it?

• Two native ports exist.

Demonstrates combining Qt and tornado, both which want to have their own event loop.
The solution is to run tornado in a thread, the issue is that callbacks will then also be executed in this thread, and Qt doesn't like that.
To fix this, I show how to use execute the callback in the main thread, using a Qt signal/event in combination with Promises.

The output of the program is:
fetch page, we are in thread <_MainThread(MainThread, started 47200787479520)>
response is 191548 bytes, we are in thread <Thread(Thread-1, started daemon 47201018689280)>
the other thread should fulfil the result to this promise, we are in thread <Thread(Thread-1, started daemon 47201018689280)>
