misc | Misc. things - Misc | Build Tool library

I have two entity classes as follows. The Parachute is the parent object and it has multiple Component objects. I need to have bidirectional @OneToMany implemented here.

Parent Parachute.java class.

I have an image (QR image) that i have to display it, and keep refreshing it every time. I tried many solutions but none worked, this is my code:

I was reading over a resource https://www.mi.mun.ca/users/cchaulk/misc/boolean.htm and I noticed the xnor simplification seems to have mixed outputs.

15a, 15b, 15c are all focusing on xnor but only 15b seems to be correct when I attempt to check.

For reference:

I'm just working on a GUI with tkinter in python. But I'm having some issues here. I'm creating a button that once it's clicked it will go back a page (Misc.lower(canvas2) and Misc.lift(canvas1)). Although i created a window for the button on the self.canvas2, the buttons is still there when the canvas is lowered.

Here is my code:

Pretty much what the title says, but I just wanted to figure out how to get my bot to send a DM to anyone and everyone who reacts to the message it sends.

I created a simple client and server using CPPRESTSDK. The client sends an image and on the server, I save the incoming file and then start doing the processing phase afterwards.

Now I want to check if the sent file is actually an image file and not some other random file. For that, I check the first few bytes of the file and this allows me to know what I'm dealing with.
This is the snippet responsible for saving the file:

I want to set up a latency command in a cog but it isn't possible since there's no client attribute in a cog, upon using self.client.latency it still gives a error

I've scala and scalajs project and it is in github for reference.

Initially I've scalatest version 3.0.3 and scalacheck version 1.13.5. The command sbt clean test is working fine.

I've updated scalatest version to 3.1.4 and scalacheck version 1.14.3.

After this updated scala project tests are working fine but scalajs tests are not.

The error I'm getting is

The changes are in this commit.

I tried to figure out but I'm novice in scalajs. Is there anything extra I need to do to work correctly?

I run my Android app (based on Java), and it works. Next, I add to my app code:

FirebaseFirestore fdb = FirebaseFirestore.getInstance();

This code I got from the official Android site https://firebase.google.com/docs/firestore/quickstart

App runs, but next the running device shows the message "app has stopped".

I use a device simulator available in Android Studio.

It is my first Android app, and I can't understand what is going.
