The Monday Night Infrastructure keynote from re:Invent was all about the changes required to support true super-computing use cases inside a placement group. The nitro virtualization layer is a huge part of it (the other being the networkin

I'm not suggesting that name. I'd prefer it was called a symplectic smooth inner product manifold. I'm merely pointing out the hypocrisy of the "name it after the discoverer argument"

A Kahler manifold is just a complex manifold with both a Riemann metric and a sympletic (Hamiltonian) form. It's not a rare class of manifolds and while the "adjective" Kahler has come to mean those properties. Why not call i

You don't find aggregation of regional deviation to national deviation interesting from a statistical perspective? Odd. Especially for someone who titles them-self "Chief Scientist"

As I said in my other comment that you chose to ignore, the probability of winning national popular vote does not indicate the probability of who will be President.

>The probability of winning is based on the popular support for a candidate This isn't actually true. The probability of winning is based on aggregation of regional probabilities. The same national vote probability distribution can

Winning the election != winning the popular vote. There are plenty of qualitative reasons to believe the popular vote distribution matches the Economist model. He isn't arguing about how they came up with distribution. He is arguing th

His tone comes off as very defensive about his own work rather than constructive criticism of the Economist model. >In that sense, the best tip-off that the forecasts are different is they have Biden at 97% to win the popular vote, and h

What's amazing is that solitaire isn't a single game with a set rules. It's an entire category of card games. The "game developers" of the past were just people agreeing on a set of rules.

If your two servers communicate over the public internet rather than a private network, all you've done is made your users believe they are behind a secure connection when they really aren't. For example, if your "old" s

Oh yea, the computer science side of things seems to rename anything related to abstract algebra as "category theory."

I love Hatcher's book so I can't disagree with you. (Although he does have a section on category theory in chapter 2, but never revisits it again). But doing anything with sheaves and schemes without categories would feel a lot li

Yea, I ask the employer/manager query problem sometimes. I'm not looking for the a right answer, but rather how they think through the problem and how they think about depth bounds. Occasionally I'll have a candidate who can
