Something that interested me this week

I mentioned last week that I (re?)started my YouTube channel after not really using it beyond a video/livestream dumping ground, and it's been fun getting back into making videos a bit more regularly! I made this one about parenthood in tech, and this one about how I've been passively learning morse code for over a decade now. I have a few videos coming this week that I've partially made, and I'm enjoying it so far!

I also built and open sourced a new project this week, FancyGist! It's a UI on top of GitHub Gists. I have some ideas in the repository if you want to take a peek (or drop a star, perhaps)!

Interview question of the week

Last week, I had you move numbers to the end of an array! To the left to the left Jacob, Jeremias, Miguel, David, Amine, Leyan, Micah, Iskren, Ridhwaan, AJ, Matt, Michael, Ten, Paul (who solved it with LEDs??), Mikaël, Toni, Phillip, Noumisyifa, Varenya, Simeon, and Roberto!

This week's question:
You have a 2D grid of numbers. Write a function that zooms in by an integer factor k >= 2 by turning each cell into a k x k block with the same value, returning the bigger grid.

Examples:

zoom([[1,2],[3,4]], 2)
[
  [1,1,2,2],
  [1,1,2,2],
  [3,3,4,4],
  [3,3,4,4]
]

zoom([[7,8,9]], 3)
[
  [7,7,7,8,8,8,9,9,9],
  [7,7,7,8,8,8,9,9,9],
  [7,7,7,8,8,8,9,9,9]
]

zoom([[1],[2]], 3)
[
  [1,1,1],
  [1,1,1],
  [1,1,1],
  [2,2,2],
  [2,2,2],
  [2,2,2]
]

Why was the programmer upset with the tester?
The tester was mocking their code.
