I have run across some issues while developing MS projects for learning purposes.

So the idea currently is that I have 2 Microservices for now:

1. User MS (UMS)
2. Statistic MS (SMS)

But on my UI I have a users page, where are all users displayed but they should be sorted by "Statistic MS" data.

Currently, I have 4000 fake users, and sending new API call for each user is insane. I have a pagination with 30 users per page, even though I'm using caching.

So it means now 30 requests are sent to get the statistics for each user this is a working solution, but very slow, and also it does not sort users based on statistics.

Because I'm getting users sorted by DESC, and just sending API call to statistics service for gathering each user statistics.

But what I need to have:

When someone opens /users page they are automatically sorted from "Statistics Service" so for example users with the best statistics would be at the top.

F.Y.I. The statistics are calculated based on user activity, that's why it's a new MS. But /users page should have a filter for this, so everyone could be able to filter through all the users with the best statistics, etc.

I am learning C and I have this project where I have to use arrays and stuff.

At the end of each case, I need to ask the user if he wants to repeat the whole program, and that's where I'm struggling.

I have tried using functions and do while loops but that didn't work.

my code right now is:

So, I'm new to Java, and I was looking at how to use a class from a Jar file. I created a java file with all the classes I wanted and then got a Jar file from it, I imported it using this interface but now how can I actually use it? I'm not using Maven or anything. Just plain java project from VSCode (Java Extension Pack and Jar Builder installed).

I know that maybe I should use a different program but I really like VSCode so If u could help here I would appreciate it :)

Here is the java file that I built the Jar from

I am new to R and am trying to vectorize an R script. However, my attempt at a vectorized version returns values ​​of mean(SAg) and sd(SAg) (see below) that are different from those returned by the original script, even if I use the same RNG (random number generator) seed.

This is the original, non-vectorized code:

In Python I'm trying to call the Windows API EnumRunning method of the IRunningObjectTable interface that I get from the GetRunningObjectTable function using the comtypes and ctypes modules (I want to avoid using other non-standard modules such as pythoncom).

I mainly retrieved and modified the code from the pages moniker.py and persist.py and the objbase.h header file in C:\Program Files\Windows Kits\10\Include\10.0.17763.0\um.

When I try to call the EnumRunning method a ValueError exception is raised:

Procedure probably called with not enough arguments (4 bytes missing)

The exception's message comes from the file _ctypes.pyd since it does change if I modify it in the file but I can't read the compiled Python code contained in it to try to understand why it's being raised.

The documentation of the ValueError exception is:

Raised when an operation or function receives an argument that has the right type but an inappropriate value, and the situation is not described by a more precise exception such as IndexError.

So the issue might be the value of the IRunningObjectTable interface that I get from the GetRunningObjectTable function. Though the function does return the HRESULT S_OK value so I'm not sure.

I have searched for the message of the exception but the information I got was about the calling convention and that some argument was missing which I have checked and does not seem to be the case.

If I try calling it with another argument I get the TypeError exception:

this function takes 1 argument (2 given)

There's only one argument so the order is correct and trying to use cdll or oledll instead of windll didn't worked either.

Here's the code:

I am learning Haskell, and as a task for myself I was trying to implement a Universal Machine from ICFP Contest 2006. I came up with a code, which, at a first glance, seems to be working. However, when I try to execute any application for that Universal Machine provided on the contest's website (e.g. sandmark.umz), my implementation is too slow to actually run anything. Self-check did not finish in a couple of hours, and I had to kill the process. So, I am clearly doing something wrong, I just don't know what.

I have tried to use Haskell's profiler, but I couldn't make any sense out of those numbers as well. Garbage collection doesn't seem to be taking a lot of time (3 seconds out of 173 seconds of a sample). However, total allocated memory during those 173 seconds was almost 6 GB, while the maximum heap size was 13 MB.

Could you help me understand, what is wrong with my code? I know that the amount of code is quite large, but I am not sure how to come up with a minimum reproducible example in my case, when I don't really know what is relevant, and what is not. Thank you.

I am working on a simple performance management system with react on frontend and django on the backend. They are supervisors who can give reviews to supervisees and supervisees can respond. I want all employees to receive email when they receive reviews from their supervisors and all the supervisors to receive email when their reviews are responded. For reviews and responses I am using two different serializers but same model.

Serializer for Response is:

Well, I need help to save a value from const map in data base. I have search on some forums, read the MongoDB docs but i found nothing, so, how I can save with for a value from a map (individually) on mongodb?

I have multiple resources, each resource pointing to a page on the application. I am using keycloak (v10.0.2) for authentication of requests. I have two users, Admin, and Client. Admin has access to all the resources while Client has access to only a few resources. After assigning permissions on keycloak, I've evaluated on the console and made sure the permissions to resources are granted as I want them to be.

Now, while accessing the application as an Admin, all the resources are accessible like it should be. But when logged in as Client, the login and couple of pages work fine but the remaining fails the OAuth2AuthenticationProcessingFilter. The following is the message from the logs.
