communicator | A monix wrapper for OkHttp | Android library

I'm facing a strange problem when trying to use MPI on a cluster, which uses Slurm as a job scheduler. On both cases, I'm trying to run this simple python program:

I have a watchapp that receives parent view model (nested view model) data from iPhone via json/file transfer. I am using "Communicator" library by @KaneCheshire.

The data flow is

1. Watch App launches - loading empty Parent View Model (ReceivedDayProgViewModel) into the app and showing activity indicator in WatchLoadingView.
2. WatchLoadingView set-up observer to receive actual json data/file from iPhone
3. WatchLoadingView's observer receives actual json data, decodes them into ParentViewModel object (ReceivedDayProgViewModel)

After step 3, I am having difficulty actually assigning the decoded object to the initially empty Parent View Model (ReceivedDayProgViewModel). There is a error message saying "**Cannot assign to property: 'receivedDayProgramVM' is a get-only property**"

So I did look up the error and have an idea that my parent View Model is actually a "computed-property" instead of stored property - How do I resolve this build issue - cannot assign to property: 'date' is a get only property But I am still struggling to add codes to ensure "set/write" function is embedded in the Parent View Model(ReceivedDayProgViewModel).

Would appreciate any guidance/advice on how I can change my code to allow "set/write" operation in Parent View Model (ReceivedDayProgViewModel) so below step can be fulfilled.

1. Assign decoded object (let ReceivedDayProgViewModel = try! decoder.decode(ReceivedDayProgViewModel.self, from: ReceivedDayProgVMData)) (with values/data from iPhone) into the @StateObject in ContentView (receivedDayProgramVM)

Using a python based Genetic Algorithm i am able to get routes for a vehicle routing problem with a heterogeneous fleet. These have to be evaluated in anylogic using discrete event simulation. I used the following blocks:

In the main, I call the python communicator and store the routes in a parameter of the type "List", then I add these routes to the agent 'Order' (of population type) such that each order agent contains a unique route and vehicle.

However, after seizing, each separate stop embedded within the parameter route from the order agent needs to be visited by the vehicle. Currently I have the moveTo block where I defined to agent with an agent 'main.Stops'. But this gives me the error that I cannot convert from int to agent.

The idea I had is to count the routes and count the elements in the routes via the parameter 'routeID' and variable 'OrderCount' respectively. These are updated after each visit and are initialized at zero. Does anybody know how I can ensure that each integer element in the route can be visited via a moveTo block (or other solution).

I have a C++ class which I intend to call from python's mpi4py interface such that each node spawns the class. On the C++ side, I'm using the Open MPI library (installed via homebrew) and pybind11.

The C++ class is as follows:

I just started using jpackage and it is a really great tool. One single step takes a lot of work off my shoulders. The more surprised I am about something that looks hardcoded and cannot be customized?

JPackage automatically generates the launcher (lib/.desktop file), and the deb package automatically installs it such that all users can launch the application. But as soon as it is launched, another icon pops up in unity. I expected that the existing icon is marked as running.

According to Ubuntu DEB installer makes all Java applications have the same icon we just need to ensure the .desktop file contains the correct StartupWMClass. Using xprop I found out this value is based on the fully qualified class name responsible for the window - which makes absolute sense.

So how can I tell jpackage which StartupWMClass to set in the generated .desktop file?

Edit: To complement Bodo's comment I will show how I call jpackage. In fact I am not running a command line myself - instead I am using the maven plugin configured as:

As the title says I have a .NET Core application that I am trying to convert over to and take advantage of the built in Microsoft Dependency Injection.

I have an object and a base class for the object, call it CommunicationBase and Communicator. When my app starts up and reads the configuration file, I can have N number of objects to instantiate.

Previously, before switching to Dependency Injection, somewhere in my startup routine, where I read the configuration file, I would have a List variable that I would instantiate and add Communicator objects to and at the same time, set some of the base properties, which changed based on how many were in my configuration and each ones properties in config.

How would I achieve this with DI?

I understand that in my services, I would register the type so it can be injected into other class constructors.

For example, services.AddTransient(); but as I understand it, this just registers the types with DI. I can inject it into a class and have a random instance of one of them.

How would I then have N number of instances and be able to set properties of each one as I create the instance?

Or, is this a scenario where DI is not necessary or won't work and I need to just do it the way I was doing it before?

Thanks!

I have to distribute an array, called A_loc, over a custom communicator (that is not MPI_COMM_WORLD). Let's suppose we want to distribute an array over mesh_r communicator:
