Unfortunately this contribution is inhibited from being significant in value by the fact that TypeScript doesn't support full gradual typing [0] and has an intentionally unsound type system [1]. [0] http://siek.blogspot.com&

Are you saying that you think perfect pitch and absolute pitch are different things? They are synonyms, cf. Wikipedia: https://en.wikipedia.org/wiki/Absolute_pitch . If you're saying that perfect pitch and relativ

You refer to perfect pitch and absolute pitch like they're different things -- do you realize that they're the same thing? My brother and I are both musicians with perfect pitch, and we've found it useful in a variety of circ

Does it seem like cultural commentary has also improved in the last 50 years? I am young enough to not remember what it may have been like when Asimov wrote originally, but it strikes me that Vice is a relatively contemporary sort of a thin

Ah, yes. Somehow I was fortunate enough to skip over that. My first couple of Macs that I remember getting second- or third-hand as a kid were a Performa 640CD DOS Compatible which was actually not bad at all, and had the interesting proper

Not only that, but seL4 [0] is a cool NICTA effort that's been ongoing for almost a decade now to produce a secure, machine-verified microkernel based on L4. It seems like there's lots of room for L4 and its children to occupy int

I wonder what the really ancient Mac he links to was. The link is broken since Apple has since drastically redesigned their support site at least once.

Your understanding of univalence seems essentially correct to me. At this point we are mostly debating what "can use" means -- it's probably enough to say that unless you reframe your thinking, perhaps radically, probably it

Yes :) My interest in homotopy type theory is only auxiliary to my research. Designing dependent type systems in a way that balances tractability with expressiveness is a pretty hard thing to do. SMT solvers are nice because you can treat t

Note that fmap writes: "Equality of rational numbers is decidable, which means that classical reasoning is provable. And yes, even if it wasn't, it would still work." What is meant by "even if it wasn't, it would st

To be clear, constructive mathematics are new to me as well. The section in the introduction titled "Constructivity" may help you -- it is about trying to come to grips with the constructive nature of type theory. The short answer

Your criticism of the book does not appear to be constructive, meaningful, or well-founded. Rather than saying "this sux, wow" and then listing your credentials, it might help if you gave some idea of what complaints you actually

Technically Coq is not a fully automated automated prover, but leaving that aside: We are definitely not even close. But getting mathematicians acquainted with HoTT is a good first step, I think. The book itself presents formulations of hom

It seems like I end up plugging the book really frequently here, but it's for good reason -- it's exceptionally readable AND it's accompanied by a full Coq development. That is, you can do basically every exercise in the book

The book on Homotopy Type Theory is quite readable even though the developments are quite new. The purpose of the book is to get the material into the hands of as many as it may be useful to as soon as possible. I would argue that the book

Great list! A lot of the stuff there is to know about functional programming is still only contained in academic papers, and indeed many of these listed books are texts in programming languages that cite a great deal of the important litera

Yes. JavaScript has dynamic types, and representing these in a statically typed language requires some finagling.

I am pleased that Microsoft has a list called "hardware junkies" :). I'd definitely be on it if I were there. Nice to know they agree with the rest of us that Samsung is the way to go nowadays, too.
