Cuddly Links Collection¶

Last update date: 06/27/2020.

My collection of web sites. Mostly CS stuff, some humanity ones.

Note: some links may be broken. This is unavoidable.

To avoid duplication, some well-known ones are expected to be excluded here.

All links are at least reviewed in detail by me.

Inspiration:

Github awesome lists
Other blogs

Motivation:

More than 100,000 Chrome bookmarks
Avoid competition with other lists on Github :D

Intention:

Keep it concise and compelling
Short summary for most links
Surprise experienced students and developers (Optional)

Note: still in progress.
