I've slept on the ground in the forest / mountains multiple times - often without shelter and often out of choice :) So there's one data point for you. I don't post that much on HN though.. That said, I do like the look

Yes. Sodium bicarbonate. Make sure it doesn't have any flour in it. Buy a tub of sodium bicarb and put it in an old shampoo bottle. Add water and mix - aiming for shampoo like viscosity. Depends how much hair you have, your activity le

I don't use R. I use [pandas] / [statsmodels] in Python. I don't do particularly special stats though. I read this [blog] earlier and as a result I don't think I'll bother to learn R unless I have to. [pandas]: htt

I agree. Zero risk is excellent. I just think that you should be willing to lose it all to get to a situation where you can zero your risk (whilst keeping a reasonable amount in).

No, you would have $1500 in bitcoins . This feels completely different to having the same in $, because you've already made the leap. Only if you had invested and cashed out would you have $1500. And then you might feel exactly the

Can you explain why? Is it to do with the bulk properties of the materials not varying with scale? Or scaling with some power of length < 3? If you tried to spec a full sized helicopter engine to make speed changes like those in the vide

Maybe it depends where you live (UK here). I see multiple cars jump multiple different red lights everyday, when the lights are very definitely red. Often the cars accelerate into the lights to get through. I also see bikes jump through lig

No, you just have to store the offset as well. And the offset for the offset. Then you just have to keep track of the number of offset cycles you've gone through - and you can store this as well. Keep doing this until you have a number

1. Well, here's to hoping. 2. He addressed this - you store the index in pi as well. If the index of the index is too big, you can store that too... indices all the way down!

It is a time-trial, a race against the clock. From an aesthetic point of view I really like the cannonball. From a practical point of view I suppose doing it does make you a bit asocial.

I agree, but this would give you a starting point in that you could see exactly what steps were used to create the figures in a paper. It might be that their high level description (usually in papers anyway) is correct but their implementat

For subjects with a lot of data analysis you could largely automate a part of the validation as scientists use programming languages. Papers would have to provide access to their raw data and the code used to process it. You could then just

"preferred (but not required)" is what wikipedia actually says, along with generic-he being the current usage (not rule). Interestingly wikipedia also states "In the 19th century, grammarians in England petitioned the Briti

Maybe £300/month was a bit ambitious for Leeds, but here's £400/month: http://www.rightmove.co.uk/property-to-rent/property-4286620... This is in Bramley / Pudsey, 4 miles out from Leeds city centre

A research paper with multiple authors - possibly in very different locations. Research often involves code as well, which would make github more suitable.

I hadn't thought of that before. So bitcoin is like gold in this regard, when gold was used as currency. It occurred to me that bank notes today are the ancestors of a receipt that promised you a certain quantity of gold. Cash is just

a 'Rankine vortex' is a fancy name for a very simple theoretical model. It's just a circular vortex in which u~1/r and there may or may not be a solid body core. A lot of spinny vortices are like this. I'm not sure

This is much more elegant than the spinning trick, as it doesn't require energy input. Works really well in deserts, if you keep the sock in the shade.

The 'Rankine vortex' is a simple model for a vortex in which the centre is in solid body rotation and the rest is a free, irrotational* vortex. From the looks of their video, the bottle forms most of the solid body core. The veloc

Ah, now I think I get it. It is demand pull, not supply push - the miners are only willing to spend money on mining because they think they can get that money back by selling. Buying mining hardware is speculating on the future price of bit

People spend money on mining - power, equipment, time. This amounts to them buying bitcoins (from the set that haven't been mined). This gives bitcoins a value in terms of existing currency (dollars etc.). They might accrue value in ot

If selling under cost makes the difference between being $10000 in debt and $1000 in debt then it matters. The latter is much easier to deal with on a personal level, because individuals tend to have support networks / savings. I'

How would coins become valued without mining? Isn't this the way that bitcoins actually become valued in terms of existing currency?

Very recently I bought a Thinkpad X200s (12inch screen) from ebay (<£200). I put in 8GB of RAM (£50) (max the chipset will support) and a 256GB SSD (OCZ Octane, ~£120). Total cost £370, which is just under $600. If you skip the extra ram

I'm not sure what you mean with the Pullman. Could you elaborate on this? It seemed like you were relating His Dark Materials to the content of the strikemag article, but are you just suggesting that we should read a good book?

I'm interested - did you actually do this or was it a rhetorical statement? @587,287 words and 400wpm, War and Peace would take just over 24 hours to read.
