I wrote a module to simulate physics of 2D elastic balls and the community helped me to improve it on this post.
Now I implemented a GUI using Tkinter to display the simulation in a window.
I'm a beginner in programming GUI and I don't know if my script can be more efficient and/or simpler.

The unicorns would be used to charge a line of infantry with their horn. They are as big as a horse and the horn is similar to this image:
The infantry is a standard medieval army made mostly of soldiers wearing longsword, wooden shield and chainmail.
If I use my unicorns to charge the enemy...

I find the default Exception.ToString() formattig very difficult to read especially if there are inner exceptions involved. I guess everyone knows how it looks:

I'm writing a little Ruby script to save email from a particular website into .txt files on my machine. The script is almost ready, but I'm not pretty sure if it is correct. Here it comes:

This is the script I wrote to make an automated POC baby-sitter in 5 lines.
I first found this on a GIF or meme site and thought of making a POC script that does the same.

Now I am trying to optimize this lock so it becomes more practical.

synchronization can have two meanings:
An issue with thread-safety / locking / concurrency
Copying and reconciling versions of data which may have diverged
The two senses of the word are barely related to each other, and probably shouldn't bear the same tag.
What should we do with the tag?
I have a case where I need to check if a string match a list of regex elements.
I'm not sure what is the best practice to apply in this case.
Which approach should I privilege ? Why?
Thank you.

with a few ORM I can see that:
$entity = new TableName();
$entity->setName('username');

I'm learning concurrency and asynchronous programming in C#. For a better grasp on the matter I'm trying to create an OLX Crawler. My issue here is the performance: It takes roughly 159 minutes to crawl 17.901 links.
The method which crawls each item is this:
