Some more free ones:

Abstract Algebra by Judson - https://judsonbooks.org/abstract-algebra-theory-and-applicat...

Linear Algebra by Hefferon - https://hefferon.net/linearalgebra/

Real Analysis by Lebl - https://www.jirka.org/ra/

Differential Equations by Lebl - https://www.jirka.org/diffyqs/

These should be enough to give you a first and second year undergrad level education in mathematics (minus stats&probability).

A chatter linked HN on #commonlisp on freenode back in 2011.

My HN viewing habit: check frontpage quickly (only the frontpage, rarely beyond that), check "new" for 5-6 pages to see if anyone has posted something cool, and then lastly check "active" and go through every page because that's where the interesting discussions are.

I used to think the frontpage was natural and unadulterated but then I learned that dang, tomhow, et al "curate" the frontpage, so you essentially see what they want you to see, but with "active" there's less of that.

These banks and consultancy companies just hoover up all the talent and bright minds from our best institutions. You wouldn't believe the amount of Oxbridge grads I've met who now work at McKinsey&Co, Jane Street, etc. This is why we're faltering in STEM when compared to China. Our brightest don't become mathematicians, physicists, chemists, engineers, and so on anymore. Instead they become bankers and consultants at vampiric companies, with the sole goal to make rich people richer.

>In a typical American or British arithmetic textbook of the same period ...

British students were taught from Euclid's Elements until around the 1970s, so he's wrong.

For me, it's The X-Files, Buffy the Vampire Slayer, The Simpsons and Malcolm in the Middle. Those are the shows I watched as a kid and I'll love them forever.

I've used them for pwncollege CTFs but pwncollege is way below your level (I've seen some of your write ups before).

Bombing people (including kids) is not "trimming the grass".

>on the Christian and Jewish sides, it's led by people who have no sincere belief in the respective religions, but hijack it for their personal power.

Have you read the Old Testament? It's full of war.

When I get sleep paralysis, I either see shadows or aliens (the typical Hollywood grey ones with big heads) surrounding my bed.

I did this as a teen but I wasn't trying to meditate. I just wanted to listen to my favourite albums without any distractions. Anyway, I'd almost always fall asleep. How do you stay awake?

For the most part, he plays normal openings. If he does play something offbeat, it's because he's trying to avoid prep.

Plus huge amounts of braindrain from all over the world after WW2 (originally from Europe, but nowadays mainly from India and China).

No such thing as a shortage of workers, just a reluctance to train natives and pay them liveable wages. Note they mention "skilled workers" then show a lorry driver and a baker. Young Germans can drive lorries and bake bread. These aren't particularly skilled jobs. When I read "skilled worker" in my mind I think semiconductor expert from TSMC who has decades of expert knowledge and experience, not a lorry driver. No offense to any lorry drivers on here.

Maybe he's saying those things because he has a horse in the game i.e. his bank account(s).

You list "operations" that occurred after Trump burned bridges with us. Why would we help you after the insults, political meddling, and tariffs? Now go look at the Iraq War and Afghanistan War, when the US invoked article 5 (the only time it's ever been invoked). In those wars, our men and women died fighting for your country.
