FIS was the text for my first “real” mathematics class and it is near and dear to me. I ended up getting a math PhD so it must have done somethings right!

The correct calculation isn’t too hard either. If currency halves in purchasing power in 25 yrs, that means inflation is 100% in 25 years, so (1 + r)^25 = 2 r = 2^(1/25) - 1 ~ 2.8%

Going to Vieques in 2011 was one of the most sublime and wonderful experiences of my life. I never felt like I was at an undiscovered treasure more than I did there: The beaches, the biolumniscent bay, the feral horses, the view over the ba

I remember being blown away when I was told about Henry Cavendish’s attempt to calculate G (the gravitational constant) in the late 18th century: https://en.wikipedia.org/wiki/Cavendish_experiment

The Well-Grounded Rubyist is my favorite Ruby book because it really drives home just how internally consistent the Ruby object model is. It gave me a deep appreciation for the aesthetics of Ruby.

That page misses my favorite XML quote, which is also on cat-v at http://harmful.cat-v.org/software/xml/ : XML is a classic political compromise: it balances the needs of man and machine by being equally unreadabl

A coworker of mine shared this neat little book which contains, among other things, descriptions of a lot of the internet infrastructure markings one can find on the streets of NYC based mostly on the author's own observations: https:

Here is an excellent video of Linus talking about why he specifically chose the GPLv2 and how he felt betrayed when the FSF released GPLv3: https://youtube.com/watch?v=PaKIZ7gJlRU

I don’t think it as as ‘tinfoil’ as people may suggest. Moves like this combined with the lift on local news station ownership restrictions make plans to ‘control what people see’ more and more plausible.

If you can make the trip to Chaco Canyon, I highly recommend it. During the day, you can spend time exploring (and I really felt like I was _exploring_) the canyon and spend the nights looking at the nicest views of the night sky you'l

I imagine the only reason Apple Maps is worse than Google Maps is because the community around Google Maps has been updating it consistently for over a decade. Apple maps transit experience is, in my opinion, much more carefully though out

I have been told that praising a kid for effort vs. results is much more important. As a child, I was told I was smart and basically tried to coast as much as possible. I still have a lot of trouble learning how to do something new, especia

I would argue that the first computer verified proof in some sense changed the mathematical aesthetic.

I am a little confused by your example, but the definition σf(x_1,...,x_n) = f(σx_1,...,σx_n) is certainly consistent and I'm not sure what you were hoping to show with your example functions. I'm really not sure what σ(2)

I just find it hard to think about playing with every set of magic cards. With booster draft, there are only a few hundred cards that you even have to worry about. Another unlisted benefit of draft vs. pauper is that almost any store sell
