Here you can find LaTex templates. I usually choose this for my talks. There is also a nice collection of templates in the ‘Academic Journals’ section. In the ‘Miscellaneous’ section there is the template for the bash cheatsheet that is here. In the ‘Theses’ section you can find the template for the classic-thesis, which I used for my master’s degree.

Update: home page of the classic-thesis package is here.

I recently find Kaobook which is a nice LaTex template for books and thesis. You can find it here. If you want to use it with TexLive integration follow the instructions here. I think I am gonna use this template for my PhD’s thesis.
