It would be helpful if this article included a description or definition of Hyperloop.

[LINK] Hyperloop officially announced — predictions, anyone?
Big tube in the air rests on pylons / support towers. Maybe goes along a highway. Vehicle inside the tube has batteries for running a compressor. It pumps air away from its front to reduce air resistance, pumps below for suspension and behind. High subsonic speed (~700 mi/hr, 1100 km/hr). Accelerated by occasional linear induction motors on the tube, like a maglev train. Vehicle estimated to cost millions, tube estimated to cost billions. Conventional rails cost tens of billions. That's all from the abstract, much more inside.

More "Stupid" Questions
Why are so many rationalists polyamorous? I don't see why this idea is linked to the LW ideology, unlike transhumanism, atheism, effective altruism, etc. which all seem to follow logically.
Adding to the laundry list of explanations and trivializations, gender skew!

Another unsatisfying Nash equilibrium in traffic control I'd like to see analyzed from a modern decision theory perspective is Braess's Paradox.

There's something that happens to me with an alarming frequency, something that I almost never (or don't remember) see being referenced (and thus I don't know the proper name). I'm talking about that effect when I'm reading a text (any kind of text, textbook, blog, forum text) and suddenly I discover that two minutes passed and I advanced six lines in the text, but I just have no idea of what I read. It's like a time blackhole, and now I have to re-read it.
Sometimes it also happens in a less alarming way, but still bad: for instance, when I'm reading something that is deliberately teaching me an important piece of knowledge (as in, I already know whathever is in this text IS important) I happen to go through it without questioning anything, just "accepting" it and a few moments later it suddenly comes down on me when I'm ahead: "Wait... what, did he just say 2 pages ago that thermal radiation does NOT need matter to propagate?" and I have again to go back and check that I was not crazy.
While I don't know the name of this effect, I have asked some acquantainces of mine about that, while some agreed that they have it others didn't. I would like very much to eliminate this flaw, anybody knows what I could do to train myself not to do it or at least the correct name so I can research more about it?
I'm sorry to drop references without a summary, but this will have to do at the moment: "Lost thoughts: Implicit semantic interference impairs reflective access to currently active information"

But that requires more than 3 things to happen.

Then he would have prepared for those >3 things failing to happen.

Every time I hear "Rest in Peace" my mind corrects with "...except not resting or at peace". Does anyone have a secular, naturalistic world view analogue? Like "whom we should remember with honor", but catchy.
Who are the (remaining) PCs in the story? Harry, Dumbledore, Quirrell, Moody... Anyone else?

Draco and Lucius, Snape, Bellatrix, Amelia Bones. Maybe the Weasley parents or Nicholas Flamel. I haven't given up on Minerva. Grindelwald is still alive and undemented.
