We have a lot of is_prime (or similar) functions: https://github.com/TheAlgorithms/Python/search?p=4&q=is_prime, https://github.com/TheAlgorithms/Python/search?q=isPrime, data_structures/hashing/number_theory/prime_numbers, etc. Shall we use one common function for that exactly identical

There is a gray portion in the topic viewer page at certain scroll lengths which looks odd.

Suggested fix is to cover the gray portion with the blue banner.

This will help reduce some copy pasted boiler plate code.

Let's add an option to rotate pinout by 180 degrees.

On all pages that are associated with a course, the LibreLingo logo on the top left corner of the page should lead back to the main page of the course, rather than the main landing page. This is because most people are most likely to only study one language, so most likely they will want to go back to that page. Once the landing page is improved, we can add an alternative way to go back to that pa

If you call input("Reasonable length prompt: ") then the shell scrolls to the right, hiding the content on the left. The reason for this is a bit of CSS width: calc(100% - 2.5em) on a div wrapping the <input> tag where the user types into the shell. But removing that leaves the input element short so that if you enter a long line of code it doesn't show the full thing. I don't know what a go

In case the PR #2249 would be accepted, the quizzes would have to be checked to ensure that the answers are correct. And this in all languages.

There is this question that will have to be corrected, but there are surely others.

Right now there is no difference between a highlight and a note. It would be nice to nicely format this in notion.

e.g.

This was the highlight in the book.
Notes: This is the note I wrote for the above highlight.

It would be great to be able to screenshot a game, similar to Pygame.

Our current firewall lab is quite simple, mostly because it is hard to set up a complicated network environment using virtual machines. We are limited on the number of VMs that can be used in the lab. With the container technology, this limitation is lifted. We are also limited to the industry experience, so a person who has real-world experience on firewalls can help us a lot.

Describe the bug
Using ep.plot_rgb() with stretch=True fails when plotting a masked array when the original array contains NaNs. Plotting returns a black plot and gives the following warning "UserWarning: One or more intensity levels are NaN. Rescaling will broadcast NaN to the full image. Provide intensity levels yourself to avoid this. E.g. with np.nanmin(image), np.nanmax(image)."
