I think the significant design decision is that in a 64 bit world, virtual address space is no longer scarce. This allows a simpler implementation, roughly half the code. The micro benchmarks are great, the whole program level benchmarks sh

I just did the math, it works out! What we need to do is move the aluminum reduction cells into floating solar powered processing units which drift around the world receiving aluminum oxide from drone craft and deliver refined aluminum back

I could believe "still living there when he was 25". Might be a corrupted context statistic. The life expectancy for males in the county (whole reservation) is 71-72 years. If 50% are dying in their "stupid nearly adult years

At something like 4 or 5 years old I lived in Pittsburgh. The zoo had an elephant with a red eye that terrified me. These were the days of bars and chains and up close displays so you could see right into its horrible red eye and after it t

They suggest a couple of explanations: those at the top may feel a) more entitled to their status; and b) more worried about losing it I also suggest that with high income inequality the rich simply do not have the ability to raise the en

I believe they are referring to a technology of the ancients where they made thin films of photosensitive chemicals, exposed them to light, then processed them to make images. The chemicals varied in which wavelengths would activate them. F

Sounds about right for mineral rights. Oil and gas leases for the US pay a 12.5% royalty.

I'm fairly certain that is just to get the worker pool. The blocks on the queue don't each get a thread.

I've built systems with libdispatch and blocks. I found it much nicer than traditional C style non-blocking IO or typical pthreads, both of which I have also done. • You don't need to use blocks, there are function callback versio

No. It's broken. The title should be longer and include "which fragmentation". Large UDP packets have a packets success rate of the single packet success rate raised to the number of fragments power, so don't get attache

If Apple decides that having the screen temperature vary with time, lighting, whatever, I promise it is easier for them to write a few hundred lines of code than it is to engineer secure holes in the sandbox, develop policy around their use

My guess is that it might have a negative effect on rendering energy consumption. In OS X you can use CoreImage to filter a view, but that has always been excluded from iOS. The platform perception management kicks in, they can't let a

I didn't see a reference to the length of the wire. But if we assume 1cm since it fits in a chip, that cycles the entire data through in about 250µS. Not too shabby for mass storage. I'm assume you build a bunch of parallel wires

A laptop running down its battery should shut itself off gracefully. That won't trigger the SSD power loss problems. It isn't a clean OS shutdown usually, but an orderly transition to a hibernation state of some variety which shou

My daughter went to pick up her ducklings, goslings, and chicks at the post office. They apologized that they had lost the box. They knew it was in there because they could hear it. They just had to move a bunch of stuff to find it.

Presumably proper names are exempt from the count. Of course now that you've raised the point, I'll probably have to waste some time today working out a simple word name for myself.

At this scale, two solar panels, so something like 1200 watt hours of energy per day I don't think you'll find a wind generator and tower to beat the price. 24 hour operation may not be requirement. Clean water stores just fine. I

I was sure you had the math wrong on that battery to mass comparison. For number appears to be very accurate. I'm going to have to recalibrate my idea of how much energy a AA holds and also physical work compared to running electronics

This gets into the other billing problem with domestic solar. In rough numbers, half of your electric bill is for energy, the other half is to pay for all the grid and capacity. Billing is purely on energy consumption. The effect of this is

"Overgeneration" is not a problem with photovoltaic panels. You simply open circuit the panel and let it sit. In my own off grid solar installation I routinely fill my batteries, and after doing any high power tasks, like vacuum t
