Sorry, but your figure is wrong. The annual US Military budget is about $600 Billion, not $600 million. That's 3.5% of US GDP and a non-trivial amount; it's more than the entirety of US trade with China (imports in 2015 were $48

You're right; I was a bit harsh. I'm just really conservative platform-wise - Node is just starting to get there. The Node/npm ecosystem does still feel a bit wobbly as an application platform, though, kind of like Ruby was

They actually pushed many of the homeless away from Market St. to just west of the Zynga building on Division street under the Central Freeway. It is indeed pretty sketchy - tents lined up in rows, broken car windows, needles and feces on

Newspapers in particular were butchered by the World Wide Web and Social Media. Paper advertising revenue is roughly a third of what it was a decade ago. That revenue paid the salaries of a lot of journalists... Of course the ones left h

I also went through a Riesling phase (various blue-colored bottles from Germany, mostly). Bottles were in the $10 range, varied a bit in acidity and fruit, but were generally quite drinkable. "Fancy" is a dangerous preference in

It isn't, though! The only wilderness place I know that is 'littered with dead bodies' is Mt. Everest. And that is from hypoxia and exposure, not getting lost. EDIT: Hmm, and maybe Aokigahara Suicide Forest in Japan. Also n

Ugh, I hope not! Nothing like ruining the joy of alpenglow with the high-pitched buzz of the nanny state.

It's true that some really lost people in wilderness find themselves off-trail, maybe fallen into steep terrain or on the wrong side of a ridge after coming down hill. If people are intentionally in trail-free 'true' wilderne

Cool! $1000 for a "Hyper HEPA" filter. Maybe a good insurance investment for the company with a room full of 3D printers... after they pay for the HVAC guy to come in and install some real exhaust ventilation duct work.

You're right! The article concerns Ultra-Fine Particles. https://en.wikipedia.org/wiki/Ultrafine_particle A HEPA filter will still do some good, though, and 0.3um is about as small as can reasonably be found on c

Intel spends about $10 billion per year on R&D, and a single fab costs about $10 billion (they build one every few years). If they want to catch Intel, they will want to at least spend as much as them, and also benefit from IP-leakage.

With all this talk about self-driving cars, it's really depressing (and tragic!) to see so little progress on self-driving trains (Positive Train Control). Think about how much easier self-driving trains are to implement! There's

I'd consider the goals similar. Both want to land and re-use orbital rocket boosters. SpaceX landed an orbital booster, but they have yet to re-use that booster. I'm sure they would rather dissect that booster, since they have a

Huge Salmon were once much more common up and down the west coast. However, they were easy to harvest (as they congregate in the river during their spawn and can be caught with nets or weirs) and so many stocks were decimated. In other ri
