so I accidentally held down something and deleted all cells in this jupyter notebook I've been building for ~2 months, and the "undo delete cell" isn't bringing them back. Lol.

I'm still shook. Some jupyter hotkey, somehow held down with my left palm, just iteratively deletes everything and undo doesn't bring them back (it creates an empty cell only). Hug your favorite notebooks and keep them safe

thanks everyone, I was luckily able to find a snapshot in the .ipynb_checkpoints/ folder. You know that annoying thing you always add to the top of your .gitignore? turns out it can actually be useful :)
