I am following the documentation for building micropython

I have a plain .NET 5 project with the default weather forecast. Running locally, it behaves as expected and the call to http://localhost:5000/WeatherForecast gives me the data. However, trying to reach the same address when running in Docker container fails. The only difference I can see between the logs is that they listen to different ports. The setup follows roughly the docs on MSDN.

Locally it is 5000/5001.

info: Microsoft.Hosting.Lifetime[0]
Now listening on: https://localhost:5001
info: Microsoft.Hosting.Lifetime[0]
Now listening on: http://localhost:5000

Containerized it is 80.

info: Microsoft.Hosting.Lifetime[0]
Now listening on: http://[::]:80

That surprises me because I published those two ports as shown in the docs. In the Docker desktop client, I can see port: 5000 mentioned (but not 5001). I tried to access Swagger on port 80 with little success (I removed env.IsDevelopment() to make sure that both dev and prod work the same way). I tried both create/start and run. Same result. According to this blog, publishing a port, exposes it too, so no additional expose in the Dockerfile is needed (although I've tested that too).

I've finally cross-compiled and linked a binary on an Ubuntu Xenial x86_64 host to run on the Raspberry Pi 4's armhf.

My toolchain's from ARM and placed in $TOOLCHAIN.

My sysroot is a loop-mounted Raspberry OS image placed in $RASPBIAN_ROOT.

This is a sample compilation line:

I'm cross-compiling for Raspberry Pi 4B using ARM's 10.3-2021.07 GCC toolchain (specifically this file uncompressed into ARMGCC). I'm also using the latest Raspberry OS image as sysroot (loop-mounted into RPISYSROOT). The host is an Ubuntu Xenial VM on a Windows host.

When using this compilation line (edited for readability, CFLAGS inspired by the Pi's /proc/cpuinfo, gentoo and GNU):

After some time (and a few updates to my mac running currently macOS Big Sur 11.4) I did try to simply start my expo app by running npm run start which in fact is the same as running expo start

This opened expo in the browser and in CLI. After a few seconds expo disconnected with error:

I have a .NET 5 Project running. I have added a COM Reference to the Zebra Scanner SDK. The SDK is built for the .Net Framework but I want it to run on .NET 5. I can build the project on my machine, as the SDK is installed on my machine.

The problem now is, that I want to build the project including the reference. So I can easily copy the generated .dll and .exe files to a new computer. Without having the need to install the Scanner SDK there.

Is there a way to achieve this? Maybe to create a dll from the COM Reference and use that?

I am building a shopping cart project.

One of the features that I am trying to build for my Cart page is an input value displaying the quantity for each product in the cart (so that the user can manually adjust the number of products) as well as a button either side of the input to decrement/increment the quantity by 1.

Here is a link to my codesandbox, and the issue can be recreated by adding one of any item to the cart:

https://codesandbox.io/s/yqwic

The logic I have built for manually adjusting the input field works as intended, however when I click the increment/decrement buttons it is only adjusting the number of items in the cart display in the navbar. The input field is not updating - however when looking at the React-Developer-Tools components debugger, the underlying quantity is updating to the correct figure - it is just not rerendering the input value in the DOM.

Can anyone point out where I might be going wrong? I tried switching defaultValue to value in the input field however this prevents me from manually adjusting the input.

Thanks

I'm working on a project for an embedded device, that uses the custom ld script. I'm using GNU ARM Embedded Toolchain version 5-2016.

In the linker script, I define a custom section located on the specific address. Here is an abbreviated example:

Trying to install and utilize the https://developer.sonos.com/tools/developer-tools/sonos-simulator/

When following the install instructions and trying to install the node package via the npm install command within the directory it fails with a 404 error trying to find node-ssdp as seen from the snippet below:
