barrage | Classroom barrage system

I've been working REALLY hard on this code and there are a few bugs but I will post the others in different questions because I hear this is a really professional website and I hate when I make mistakes. Anyway, I've been working on this for a while but I want to make it so that when the player gains a certain amount of XP, to have them level up. I do not have the level battle's code yet, but how would I make it so that the player will automatically level up upon hitting a specific number of XP?

Here is my code:

I am trying to use depth first search starting from a particular vertex. For that I need to supply a visitor and a color map.

If I don't supply a starting vertex then I don't need to supply a color map either and everything works fine. However, I didn't find a signature that would accept a starting vertex without requiring a color map.

I use C++ 17 (Embarcadero C++ Builder) Here is the code:

Trying to grant lake permissions via a Lambda Function. (Python 3.8) As far as I can see, I have my code as per documentation. Yet hitting a barrage of nonsense errors about parameters being incorrect. Could it be that I just need an optician ? Or is it some nuance or which way the Amazon wind blows today ?

I am new to async functions. What I currently have is watchPosition(), which fires whenever a new position is detected. Well, what I need is to find a new speed every second. So, I want to call getCurrentPosition() every second, to record the speed of the user. I get a big backlog when I use setInterval() with getCurrentPosition().

What I want (time, speed):

I am having a great deal of trouble installing kivy on my system. I have had this working before but for some reason am having an extremely hard time right now. I follow the directions verbatim, setting up a virtualenv, activating the env, installing the dependencies (docutils, pygments, pypiwin32, kivy_deps.sdl2==0.1*., kivy_deps.glew==0.1*., kivy_deps.gstreamer==0.1.*).

all of that part above works fine. when i finally go to install kivy (py -m pip install kivy), i get a barrage of errors:

I know one can use show products by taxonomy but what if I would like to show all products in one view no matter the category the product is in?

Is it possible in Sylius or do I have to write my own controller that will use query builder to output all of them? And if yes, then how? Iterate over all taxons and throw barrage of queries at ORM?

A UICollectionView will consist of a feed of videos. When the user is inline with a video, I would like it to play. With my current setup, several videos play at once (I suppose depending on the pagination) once they are loaded in to the collection view.

How do I play videos inline in a UICollectionView?

A cell in the UICollectionView feed will contain a UIView, which will hold the video player. This is the UIView's class PlayerViewClass:

I have an App Engine service running Python 3.7 (Standard Environment) that is a push subscriber to (and therefore triggered by) a Pub/Sub topic. This program can run for a long time. I need to be able to acknowledge the message immediately and then continue running, so that the service doesn't continuously receive the same message.

I see two possibilities here:

1. Ideally I would like to be able to acknowledge the message and then let the program run its course;
2. Alternatively, given that the service is idempotent, I could just let the service be barraged with the message, ignore all repeat messages, and then acknowledge once at the end of the program.

I think Option 1 seems more appealing- but I don't know if it's feasible in Python. As far as I know (please correct me if I'm wrong), the message gets acknowledged by the returned 200 status at the end.

I've put the basic skeleton to the program below. Any ideas are welcome, thanks!

I have a web page in HTML, with different page having some sections like below image

I need every sections to be of the same height, the first section in the image is perfect with the section only till the screen, but the second section in the 2nd image is a little below the screen like below

I need it to be like the first section, till the screen. My code:
