Microcosmographia Academica http://www.cs.kent.ac.uk/people/staff/iau/cornford/cornford.... It's not quite a blog post, but it's as close as one might have come in 1908. I also lik…

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 ty…

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 sayi…

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, a…

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 stri…

> Think of me as an MSR guy publishing a paper, it’s just on my blog instead appearing in PLDI proceedings. I’m simply not talented enough to get such papers accepted. I wonder if …

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…

We got into Feed The Beast, a curated collection of modpacks for Minecraft, this year. Played a whole lot of that. I've been playing the Hearthstone beta with a few friends for a c…

The tech report version of the OOPSLA paper Joe mentions, about a type system for side effect understanding, is here: https://research.microsoft.com/apps/pubs/default.aspx?id=170..…

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 …

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.

I found this article really interesting. I started using Facebook in high school, back when high schoolers were to use hs.facebook.com to access Facebook and networks were heavily …

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 y…

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 ha…

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…

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 co…

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 y…

Thanks! I tried to answer it.

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…

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, yo…
