sayhello | A simple message board application build with Flask

I'm using the zbus crate to make a server able to get events from the dbus. It works well my code (basically the same as the example from the documentation) is able to receive events so it's fine.

I use busctl to send an event like in the example:

Learning about the concept of microservices in Nodejs, I have set up two microservices auth and users, both standalone and running on different ports.

The auth service handles user creation and log-in users using a username and password. This works as expected. I've used jwt to generate the tokens. I can easily create a user, create a session token and verify its validity.

My second service, users, I intend to use to show greetings to users and fetch a user's detail. I need to use the auth service to know when a user is logged in in this setting.

However, with my current workings, when I try to go to an endpoint, /users/:id/sayhello with a valid user id and a valid token passed in the headers, I get the following errors:

TypeError: Cannot read properties of undefined (reading 'id') at /path/auth/verifyToken.js:23:21 .

And then this; from jwt:

My log4j does not record any log file. I am not sure if this is a problem from the settings inside log4j.properties or the location of this file.

The way I built the project:

I tried create my custom plugin for Flutter on Kotlin. I accessed the methodChannel and was able to do it, but when I want to use the bluetooth service in the methodChannel i am faicng this error. I did on Kotlin and my code ran correctly. The difference is My kotlin app's class is of type AppCompatActivity() and has onCreate() function. My problem was not solved when I added the onCreate function to my scanner.kt file. I get this error.

I am new to using Argo Workflows. I have written down a sample workflow for demo purposes. Below is the attached workflow YAML in which I am facing this issue in the last step. The last step sayHello is erroring out with exit status 2 and the logs show up the error to be :

'/bin/sh: arithmetic syntax error'

In my iOS project, I want to call a C++ function from my Swift code that takes an object from my Swift code and returns another object.

So far, following this tutorial and adding a little bit more stuff, I managed to call a C++ function that takes a simple parameter and returns a string:

• I create the NativeLibWrapper.h file:

I am currently trying to create a COM object in .NET Core 6. To achieve this I have made a class library and edited the project like this:

C#:

Project file (*.csproj):

I have one proto file for gRPC server

I have a method decorator that allows to execute a decorated method only once.This function works good,but at my third unit test it failes because it gives undefined but should return first execution result.
This is my decorator:
