Ask HN: How did you learn math notation?
5 by rullopat | 5 comments on Hacker News.
Hi all! I'd really like to learn "higher level than highschool" math as a (long time ago) college drop out, but I find it really hard to read anything because of the math notations and zero explanation of it in the context.

John Wick Pinball Machine Announced, Touts Pinball’s First AI-Augmented Software

The next Stern Pinball machine will be based on the John Wick movie franchise, including music, movie clips, and likenesses of all major characters – most importantly that of Keanu Reeves, who graces the art and presumably many clips of assassinations.

Friendships, romantic relationships, and everything in between have always been an integral part of not just the Dragon Age series, but of BioWare in general. From Mass Effect’s Garrus Vakarian to Dragon Age’s Varric Tethras, the characters – and how they get along with the player – are inseparable from titles from the studio. But, perhaps more than any other BioWare game, Dragon Age: The Veilguard is leaning in heavily on this idea, as it’s already easy to see from the marketing material. For one, the name changed from Dragon Age: Dreadwolf back in June, with BioWare general manager Gary McKay telling us at the time that it was out of a desire to shift the focus to a “really deep and compelling group of companions.” That would be followed by a first official trailer at Summer Game Fest that put the focus squarely on seven new companions that will be tagging along with the player character, Rook, in The Veilguard. With all that in mind, it’s little surprise to hear game directo...
