CS 50 on Edx is a good introduction to computer science https://www.edx.org/cs50

Classic racing and flight sims such as Grand Prix Legends, Mig Alley/Battle of Britain and Falcon 4 are available for linux here:

(this is free, and does not use steam)

It is not the case that free universities are necessarily 2nd tier. QS World Univerity rankings puts ETH Zurich, a free university, as #6 overall. Times Higher Education world ranking lists ETH Zurich as #13 overall.

The other Swiss flagship university, EPFL, which is also free, is ranked #14 overall in the QS world ranking.

What is this ranking site (QS world)? Not to dismiss it outright, I'm just usually suspicious of any rankings aggregator of universities at this point.

The interplay between CS innovation and computer games goes all the way back to the days of spacewar and Ken Thompson's chess programs.

With this in mind, I put together a free linux compendium of classic PC simulation games: https://alternativeto.net/software/esports-for-engineers/

This was a way of building up momentum to work on more serious projects.

Citizen's Climate Lobby (CCL) does non-partisan lobbying for carbon fee and dividend in the USA, Canada and the EU. They lobby on the local and federal level, getting endorsements, tabling, getting bills introduced and writing articles and letters to newspapers. A list of CCL accomplishments is here: https://citizensclimatelobby.org/about-ccl/accomplishments/

Excellent open source ML sparing partners for Chess and Go are available: https://github.com/bencaddigan/esports-for-engineers

But what about Contract Bridge? Is there an open source program that will play the other three hands? A machine learning program would be ideal, but any decent open source program would be fine.

"Average expected contribution" is not precisely defined in the Harvard document you provide, and thus does not commit Harvard to any particular course of action.

Harvard does not cost full-sticker for most people who attend. Most people who go are very rich, sot hey pay a substantial fraction of full-sticker, but if you aren't, you won't.

Yeah I just added the parent expected contribution and the student work contribution to get around 15K, either way it is pretty clear that students on aid (the majority of all students) aren't paying anywhere near 60K.

Also per that NYT article on wealth at colleges ~15% of Harvard frosh come from the top 1%, so that's a decent chunk of the remaining 45% that clearly don't need aid and likely did not even apply for any.

I doubt you will find many people out there that feel they paid too much for Harvard. Certainly there are bigger fish to fry as far as college tuition rip offs.

It is not the case that Harvard is free for students whose parents make less than $65K. Read the small print.

If they make less than $65k and don't have significant college savings/assets, then yes it is free.

If you're a hedge fund manager who just retired and is now making $0/yr, sure it's not free.

Are there other projects similar to Gemini? Of these projects, which is most likely to still exist 5 years from now?

I don't know, are there? I don't know, do you?

Art of Problem Solving is popular with the Math Olympiad types. I see that others on this thread have recommended it already.

I second this. Do t be scared off by it being for math Olympiads. A lot the first volume deals with concepts across much of the field. Lots of practice and ideas for logs, exponents, word problems. And it comes with a solution guide which helped me a lot.
