1806 VS hn-search

+1 for Gilbert Strang’s linear algebra textbookcourse. Im working through his textbook now as I’m diving deeper into ML/DL methods.

Here is an additional link to the Spring 2023 course materials that follow along the 6th ed. Of his textbook [0].

I've gotten the most use out of these lecture summaries with Jupyter notebooks. They've taken me from linear algebra being a scary black box that I hope doesn't hurt me to something whose principles and use I'm comfortable with (augmented with some secondary sources on occasion). It's sprinkled with practical advice, like:

MIT has a revised linear algebra course where you avoid echelon forms and teaches the svd from beginning but lectures by Edelman got paywalled https://github.com/mitmath/1806/blob/spring18/summaries.md his matrix calculus lecture for AI still on YouTube, nobody else teaches it

It depends on what you want to do. If you just want a working knowledge of linear algebra that you can use in statistics, data science, etc. then Strang's course is *nearly* good enough to just go forward. In particular, you should read up on PCA (I found this very useful: https://www.cs.princeton.edu/picasso/mats/PCA-Tutorial-Intuition_jp.pdf) and don't fade on SVD!! It is extremely important in all sorts of applications! In fact, the 2020 version of 18.06 is restructured so the SVD is covered over multiple lectures, starting as early as lecture 5 (https://github.com/mitmath/1806/blob/master/summaries.md)!

Truly good websites have around 2 facts per 10 word sentence, and get instantly to the chase. Also: good websites give you the names of all their competitors/alternative websites before showing their own stuff, and give you further reading.

Right now the world of technology is supposedly more innovative than ever, but somehow Wikipedia (https://www.wikipedia.org/) and Search Hackernews (https://hn.algolia.com/) beat billion dollar search engines.

Articles written decades ago are still unsurpassed in terms of quality and ease of understanding, but the best modern websites can do is textbook explanations. It is time society graduates from boilerplate buzzword textbook culture.

Now the gems of the internet are slowly being buried beneath mountains of trash.

If something sounds boilerplate it isn't good enough.

Don't bother saying something that has been said before, and better.

Oh, I see. We actually discussed Pound about four years ago - just a little back and forth about the ABC of Reading: https://news.ycombinator.com/item?id=24196681

>What's your explanation of why Pound went Fascist?

I'm not sure I particularly have one; I haven't read any of his longer political or cultural (i.e. non-literary) works. I just think it's silly to correlate an approach to translation that you dislike with fascism. Especially as I'm not sure it even makes sense on its own terms: I can only read your comment as 'lazy translator? Figures that he would be a fascist', but if I imagine the type of translation a fascist would approve of, the approach I picture is fastidious, fussy, concerned with fidelity to the point of stickler-ishness. (Isn't that from where we get 'grammar nazi'?)

And oh, well, since you ask I'll take a shy at it: my vague sense is that he became fascist because saw a society in decline due to it becoming more and more a sham society: opulence without virtue, power without vigour, money no longer tied to actually existing goods. (Of course, all of this shades easily into antisemitism.) He saw fascism as the answer; It's easier to see in retrospect that it wasn't.

"multiplayer notepad" goes back 15 years at least - https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu... notepad&sort=byDate&type=comment

it was used back with a popular website which opened a text document and anyone viewing could type, but I can't remember the name. That became a thing in Google Docs, Microsoft Office, Floobits, and lots of self-hosted and cloned sites.

If you see a post that ought to have been moderated but hasn't been, the likeliest explanation is that we didn't see it. You can help by flagging it or emailing us at [email protected].

Ok, but please don't post unsubstantive comments to Hacker News.

I understand the reason for repeating these sentiments—it's the same reason why they get upvoted to the top of threads*—but repetition of this kind is what we're most trying to avoid here.

* I've marked this one off topic now.

I was looking for it in the guidelines. There are a couple of conventions for postings. Consider a bit of prior examples: [https://hn.algolia.com/?q=show+hn]

yeah there are only three stories coming up from the site search

https://hn.algolia.com/?q=postgres+clustering

only one is semanthically correct, the other pick up the wrong version of clustering (i.e. k-means instead of multi master writes)

but yeah if one doesn't test the hard cases, how does one know it preserves semantics :D

Like dismissing the work of Feyerabend or Wittgenstein without seemingly having read either:
