Ask HN: Anyone have any sources similar to this (linked below) but for CS

Hello!

I came across this site [1] earlier today on Reddit. It is well organized and has decent sized articles [2]. It looks like a digital textbook with digestible information. I'm wondering if anyone has anything similar to this style and quality but for CS. I'm not necessarily looking for a particular area/field of cs, so I'm open to any and all. Thank you :)
