Re:How housing became the world’s biggest asset class on Wednesday January 22, 2020 @01:15PM (#22120273)
Some reasons I think people like housing as investment: They can use relatively safe leverage to increase the return on equity by three or four times. There are large tax incentives. There is the time value of money aspect where you pay off a fixed amount over 15 to 30 years. Also, housing is a hard asset unlike stocks or bonds.

I work in legal tech nlp/automation right now. I'd like to chat.
It's interesting to read how Buffett and Munger made their money. They definitely didn't make it by investing in index funds.

What Munger is really encouraging in his talks is intelligent allocation of money, knowing the boundaries of your knowledge, educating yourself, and recognizing basic human psychological shortcomings (like mistaking speculating for investing).

Re:Why is perl losing its touch? on Sunday February 22, 2015 @01:11PM (#9090267)
This one page isn't a good indicator of a language's popularity. It probably includes results referencing Monty Python, as indicated by the news article headlines, or the animal python.

The TIOBE index might be a better indicator of programming popularity using internet search results:

but that's still not perfect. You could also look at the number of job postings on sites like Indeed asking for Perl experience.

It would be cool if you could search arXiv.org with this or maybe even subscription math/physics journal sites like JSTOR. Paid search results might be an opportunity for partial funding but I know that's not everyone's cup of tea.

I always liked this visual representation of the central limit theorem: http://blog.vctr.me/posts/central-limit-theorem.html. There is a faster one here (I think written in R): http://vis.supstat.com/2013/04/bean-machine/

These are computer simulations of Galton boxes: http://en.wikipedia.org/wiki/Bean_machine

As a math graduate student, I second the choice for Abbott's "Understanding Calculus". It's a wonderful beginning book for analysis. Walter Rudin's "Principle's of Mathematical Analysis" is an amazing book but it's difficult to start with.

For a quick intro to Lebesgue integration you can read the beginning of Rudin's "Real and Complex Analysis" or Halsey Royden's "Real Analysis".

I haven't read Axler's book. I liked Hoffman and Kunze's "Linear Algebra"
