Indeed. It's abstaining from all food and drink for a goal of 24 hours. I generally manage about 12, but it's something I'm working on improving.

If I had a big test coming up, I wouldn't experiment with fasting on the day. However, if you've been fasting while studying and you find it to be a help, then fasting the day of the test is probably a good idea.

Fasting is a periodic religious observance for me. The main effect I have noticed is increased irritability, but then I've never done cognitive tests while fasting.

I believe so. I had assumed you were referring to the general case, sorry about the misunderstanding.

Can you phrase that question in a way that takes relativity into account? In particular, what do you mean by ticks being synchronized between two observers, when there's no such thing as objective simultaneity?

The MIT team explicitly addresses the limitations of refrigerated dew collection systems and claim that their system does not share those limitations. In what way would this particular device not work as advertised?

Is quantum error correction really that demanding? I thought it was only a small multiple of the number of qubits, not orders of magnitude more.

by Zaak 9y ago
That would be fun to watch, but to be overly pedantic about it, it will take a computer with hundreds of qubits to break current public key encryption.

My understanding is that the center core was nearly a complete redesign because of the greatly increased load from the side boosters.

When I was getting a dental implant to replace a badly decayed tooth (protip: get broken teeth fixed), my dentist used the same sort of thing.

According to http://www.nuscalepower.com/our-technology/technology-overvi... it would have a refueling cycle of 24 months. I didn't see anything about the expected lifetime of their reactors.

In a similar vein, the real task of debugging is not to make the program stop doing the wrong thing. It is to create in your mind an understanding of why the program as written necessarily behaves in the way it does. Once you have that unde

> you are paying for a compromise Very good point. Apparently including at least one compromise that most people (probably including the engineers who designed the CPUs) didn't know they were making.

It can't have a similar metabolic effect to sugar. For one, it's a peptide, not a carbohydrate. Also, in the quantities it's consumed in, there are very few calories. Now, for phenylketonurics it's problematic, but they

The pure purples are not in the rainbow because they are a mixture of red and blue, whereas the rainbow is made of single-frequency colors.

Isp just says how efficient you are at turning reaction mass into delta-v. Nuclear rockets can attain both high Isp and high thrust.

Exactly. UEFI is a bad idea implemented badly.

ECC is vulnerable to Shor's algorithm, which gives exponential speedup. A rough calculation implies that 256-bit ECC would take on the order of 25k quantum operations to break.

SIDH keys are 330 bytes long when compression is used, so they too will fit nicely into network packets.

A digitally controlled analog computer is a good analogy. One big limitation of quantum computers is that they can't erase information without losing their quantumness. So simple things like if-then statements become impossible (you&#x

Yeah, if you have a 5000-qubit computer and two people want to run 2000-qubit jobs, I can see them being able to run simultaneously. There will always need to be a classical computer running the quantum computer.

Symmetric encryption will need to double key lengths, such as using 256-bit AES keys instead of 128-bit. All currently popular forms of asymmetric / public key encryption (including RSA and ECC) are vulnerable to quantum attack.
