Prog1 | Exercícios propostos nas aulas de Programação

I was making a program with Haskell and it's IO, when I came across an error I don't understand. When I use a where statement after a do block it does not do the same thing as without the do block.

The program that works is:

When I run a python program (2.7 or 3), I import a module that has a class that initializes some threads. The problem is whenever an uncaught exception occurs in the main thread, the main function dies yet the thread keeps running like a zombie causing the python process to never die.

What's the best way to have any uncaught exception in the main thread (or even other threads) to kill everything everywhere.

Since I often call the subprocess module, I usually use threading.Event to help exit cleanly. However, uncaught exceptions won't trigger those events.

Here's an example of a program where the thread just won't die....

prog1.py

I have 2 similar Spark Dataframes df1 and df2 that I want to compare for changes:

• df1 and df2 share the same columns
• df2 can have more rows than df1 but any additional rows in df2 which is not in df1 can be ignored when comparing
• Comparaison key columns are PROGRAM_NAME and ACTION

I am learning using-directives, and trying to understand the name lookup rules for using-directive, but I encountered this problem and I cannot found any explanation.

The problem looks like this:

prog1: namespace C is outside of namespace A:

When I initialize a vector in C++ like this:

im using draco to encode and decode my meshes. But draco does not support to webgl (https://github.com/google/draco/issues/436). However, Draco supports javascript. And is that possible to run the Draco javascript decoder inside the unity? that is my .jslib file under the assets/plugin

I have to call one prog1.exe program and give arguments to it and give it's output to another executable prog2.exe in a bash script

I am a beginner in React, and I would like to make a web app with a dashboard like Windows tiles. I generate them easily. But I want when I click in one of them, that hide the Dash menu and Display the sub-app "Prog1". And of course, reverse it. When I click the close button, it closes the sub-app and returns to the Dash menu (implying that it hides the Prog1 to display Dash).

I can hide the Dash menu with a function like this:

I am trying to implement various project from a programming book. My intention was to have each project exercise in its own folder and then have a makefile that compiles all of them with something like a make all. The folder structure is like this:
