Jeff Sarwer was the intimidating 8-year-old chess prodigy who drew against Josh Waitzkin to share a US Junior Chess championship title (the basis for the dramatic finale in the film "Searching for Bobby Fischer"). He's a professional poker player now.

Jennifer Shahade also interviewed him for the USCF website a few years ago: http://www.uschess.org/index.php/January/Lost-and-Found-An-Interview-with-Jeff-Sarwer.html

Discussion of various techniques for dispatching instructions in virtual machine interpreter. (I got here while reading about Forth and "threaded languages".)

Issues of BYTE magazine on the Internet Archive.

From Wikipedia:

"Byte (stylized as BYTE) was an American microcomputer magazine, influential in the late 1970s and throughout the 1980s because of its wide-ranging editorial coverage. Whereas many magazines were dedicated to specific systems or the home or business users' perspective, Byte covered developments in the entire field of "small computers and software", and sometimes other computing fields such as supercomputers and high-reliability computing. Coverage was in-depth with much technical detail, rather than user-oriented. Byte started in 1975, shortly after the first personal computers appeared as kits advertised in the back of electronics magazines. Byte was published monthly, with an initial yearly subscription price of $10. Print publication ceased in 1998 and online publication in 2013."

Andy Gavin and Jason Rubin provide a multi-part retrospective on developing the PlayStation game Crash Bandicoot.

I only played Crash for maybe 15 minutes at a friends house back when it was released, but it is the first time (other than maybe Marble Madness) that I felt like a 3D game worked.

A neat twist on chess tactic puzzles where you have to do a bit more visualization to solve the tactic.

They've also recently added pieceless tactics for even better blindfold practice: https://listudy.org/en/pieceless-tactics/1203
