1) This is how ethernet works, if your ethernet cable have not connected, no connection and no IP address there. Sharing network over USB, as I know works fine on macOS, but not sure how to configure it for Windows. With macOS, it's possible to connect RaspberryPI with MacBook with USB-c to USB-C cable, and it will power it and gives access to the network.

2) Upgrading Docker-based applications, it the topic right for Docker. It's not so easy to explain how to upgrade Container. Containers are stateless, and the process is just to stop the existing container and start a new one from the updated image.

You don't have to extract archives supposed to be used by Docker. They have to be used as-is with command

docker load -i iris_community_arm64-2021.1.0.215.0-docker.tar.gz

and this will load the image to docker, and then it can be used there

Yes, InterSystems, offers distributions of IRIS, which can be installed without Docker. And for sure, you can run as many instances of IRIS as you want, as soon as you have enough resources for it.

Yes, when you created a new class, it is just a file on your local disk. When you saved it, VSCode caught this action, and sent it to the server, and compiled it. But deleting this file, not a reason to do the same on the server.

You can delete class with Explorer view, there you may find any classes, that are stored on the server. By context menu you can Delete the item on the server, or Export it to get the local version. Icons close to class names, the same as in File Explorer view, may indicate the connection to your local file.

github.dev, is just a simple VSCode but in the cloud. It may get a coloring if it would allow at least our main extensions for ObjectScript, which in fact provide a basic coloring. GitHub.com itself uses coloring from another source, which in fact almost the same as for VSCode.

I'll look at github.com, and maybe I will find a solution, how to get coloring there somehow. And thinking about Codespaces feature as well.

As I know, there is no way to have a schedule for the whole production. Just only services can have scheduled.

With working hours 8:00-18:00, will be something like this.

START:WEEK-*-01T08:00:00,STOP:WEEK-*-01T18:00:00,START:WEEK-*-02T08:00:00,STOP:WEEK-*-02T18:00:00,START:WEEK-*-03T08:00:00,STOP:WEEK-*-03T18:00:00,START:WEEK-*-04T08:00:00,STOP:WEEK-*-04T18:00:00,START:WEEK-*-05T08:00:00,STOP:WEEK-*-05T18:00:00
