End-note

• Just documenting some links which either I have ended up looking for again and again or I anticipate I will need to look them up again and again. So just saving them here for myself.
• While I have tried to categorize based on primary content, there is a lot of overlap.
• If you see some deadlinks, please let me know (@SNChd on Twitter)
