The advantage of OSM is that ability to host if offline. I used OsmAnd+ on my droidphone for offline maps and navigation, and it expertly got me through Europe great.

Google Maps for mobile devices fundamentally fails because mobile data coverage is far from ubiquitous or reliable for something that important.
I recently bought a Blackberry because of its built in encryption features. It's a great phone but is missing two popular apps: Evernote and Audible.

If you made an app to substitute for either one and charged a few bucks for it, you'll make passive revenues for a long time. Not only that, you'll be loved by crackberry users the world over.

Seriously, how many business types subscribe to Audible and to Evernote? And people are looking for more secure communications. It's an incredible opportunity.

200 req/s is not that high and Ruby servers have a bad track record in general -- Puma's README (https://github.com/puma/puma#readme) also mentions that the Global Interpreter Lock on the Ruby MRI is terrible for performance.

Then again, it would be nice to see a proper benchmark of Puma against other servers. Something in the lines of https://github.com/Versal/scamper#readme would be great (note that the top frameworks do 60k req/s, albeit on a very beefy box).
I agree with this, which is why the new Google Maps rubs me up the wrong way. I don't like how it changes the emphasis of different streets and roads depending on what you've searched for. A major road is a major road, and shouldn't turn into a minor road just because the restaurant you clicked on isn't on it.

We look at a map of our town or city, and the main roads in and out are the spines - everything is off one of them. If you turn those white, and remove the emphasis, the map becomes far less readable.
That depends on the design. Molten salt and pebble bed reactors for example cannot fail catastrophically - it's physically impossible for either of those designs to do so.

But I agree with you on the economics. The alternative to not going nuclear energy is running out of oil or not being able to afford it. The initial expense is irrelevant in that light.

I've had a look (but not intensively, it's a back-burner thing for me at the moment). Everything seems very heavyweight and aimed at big businesses with long supply chains.

For a small ecommerce retailer, you don't want much like that; maybe I've missed it but there seems to be a gap for the Basecamp of this niche. A shopify plugin might be a good way to get standardised i/o rather than adapting to proprietary systems

No, that's exactly what the author tells you is not true:

"And they [pro-nuclear crowd] are probably right that the risks of radiation have been historically overblown as “junk science” wormed its way into popular culture."

Nuclear power is the safest power generation tech we have so far [0]. It's actually hydro that can screw you really hard when it fails (and your design sucked) [1].

Normally, if you face a really complicated economic optimisation problem, you can cheat a "good enough" answer by seeing what the market has come to favour.

But the energy market is a very political market. So there's really no way to get a good feel for it any more. As I said elsewhere, for the medium term I see gas winning. It's "greener" than coal and it's cheaper and more compatible with existing systems than solar/wind.
Or if a coal spoil tip slips and wipes out a school lookup the aberfan disaster on wikipedia.

And thats just one of many mining disasters (hundreds die every year in china for example) - which puts even Chernobyl into perspective.

Hey,

just to let you know. There is a hard 10GB limit on SimpledDB, which cannot be changed. Also there are rumors that SimpleDB will get deprecated in favour of DynamoDB.
Most people aren't going to think of that in time. I've had my accelerator stick under the carpet before. There was a good few seconds of panic there that would have been deadly had I not been on a straight highway.
Most NASA missions are not likely to cause a risk of large radiation leaks if something goes wrong. The likely failure modes and consequences of a failure are vastly different.

And you seem to assume that there'll be a lot of new development for these systems, as opposed to very careful maintenance and small upgrades to complex existing systems.
Plumbr 3.0 announced + sneak preview of next features
Coal's emission profile depends a lot on the coal. Anthracite burns very hot and produces almost pure CO2 (instead of more noxious byproducts), but few deposits are anthracite.

For example: here in Australia, the New South Welsh are burning high grade anthracite coal in the Hunter Valley [1]. Meanwhile in Victoria they burn lignite [2]; it's basically ambitious peat moss.

The NSW plants produce more CO2 per ton of coal burnt, but their environmental impact is lower -- they produce more KWh per ton of CO emitted.

To be fair, the Tegra 4 chip supports almost all OpenGL ES 3 features (via OpenGL extensions), but it lacks some checkbox items to be able to claim GLES3 conformance. Little things like numerical precision of the rendering pipeline, which will not have a giant impact on most game content but is required for conformance.

And as of today, nobody else has shipped a GLES3 device either.

It is very likely worse. GAs and ESs are good only if you can't come up with a dedicated heuristic that understands the structure of the problem it aims to solve.
Disclaimer: I'm pro-nuclear. I'd happily pay twice as much for my electricity as I do now if it meant less poisonous hydrocarbons being pumped into the atmosphere. I'm not in favour of Nuclear because it's sudddenly going to eliminate energy costs, I'm pro-Nuclear because it means we can have cleaner air again, and less people dying from coal and gas related pollution.

Factor in human life and the economics make a lot of sense.

Google Maps on Android at least allows downloading maps for offline use. I've used it lots of time when traveling and it works great.

The only slight downside is there is a limit to how big a single downloaded map can be. So if you want to download all of Europe you have download it as a whole bunch of smaller maps and switch between them rather than a single big map, but realistically I've never run into problems with the size limitation

You might want to read up on the AVR reactor (an pebble bed reactor). The reactor assembly is so radioactive that it will be stored for 60 years first, before they can safely dismantle it.
And as for pebble bed reactors cannot fail catastrophically.. AVR almost did (water leaked into the He primary cooling cycle).

The copyright owner can license under whatever license they like. As many have said even before it was sold to Sun all contributions needed a copyright assignment before they were accepted (so they could sell the option to make closed source modifications amongst other things) so Oracle can now license as they wish.

What they can't do is revoke the existing GPL licenses so you can still develop and modify the old docs.

Having said that this is Oracle and you should probably just run for the hills (MariaDB) before Oracle make it hard to make it fully compatible with future version of MySQL by doing something else.
(Danger: very very handwavy calculations ahead. Treat the result with caution, or even contempt.)

One photon of light at wavelength lambda has energy hc/lambda and momentum h/lambda; in other words momentum = energy / c. If the asteroid is near earth then it's getting about 1kW/m^2 of light energy from the sun. So for each m^2 of area and each second of time, that's 1e3 / 3e8 kg m/s ~= 3e-7 kg m/s of momentum; if the asteroid is, say, 99942 Apophis then its mass is 4e10 kg; let's call it 3e10 kg, for a net acceleration of 1e-17 m/s^2 per square metre of area. If adding the mirrors replaces absorption with perfect reflection, then that's also the size of the change in acceleration they produce.

According to Wikipedia, which is always right (except when it's wrong), averting a collision t years in the future requires a velocity change on the order of 0.035/t m/s.

If we assume (this seems pretty damn dubious to me, but never mind) that the effect of our extra momentum from sunlight accumulates "perfectly" over time, and if we suppose we have 10 years' warning, and if we handwave away some details, then each m^2 of mirror gets us 1e-17 m/s^2 * 3e8 s = 3e-8 m/s of velocity change, and we need 3.5e-3 m/s. So we'd need about 10^5 m^2, or a patch 300m on each side. That's a lot of bees.

In practice, you won't get perfect momentum, and the asteroid may not always hold the same face to the sun, and the changes may not accumulate in the way you want and may be in an ill-chosen direction, and all the numbers above are only approximations, etc., etc., etc., so you probably need more than that to have much confidence of saving the earth.
> To provide baseload-ish power, you need multiple installations to cover that different areas receive power at different times in a stochastic fashion and you need backup plants just in case your multiple solar farms are shady or the wind stops in multiple places.

Absolutely, and the different areas you need to cover have to be very far apart, most likely distributed over multiple countries. This is covered in the excellent Without Hot Air:

http://www.withouthotair.com/c26/page_187.shtml

"Between October 2006 and February 2007 there were 17 days when the output from Britain’s 1632 windmills was less than 10% of their capacity. During that period there were five days when output was less than 5% and one day when it was only 2%."

So if you build half your capacity in solar and half in wind, you'll find edge cases where it's night and the wind isn't blowing, and you're suddenly generating 1% of capacity overnight.

This is aggregated over the UK, which is a very small country, but it still highlights the magnitude of the problem.

There are quite a few potential solutions, none of them good; country scale storage (a Tesla can power an average American home for more than a day). Solar thermal, where if you store enough molten salt you can generate at night. Triaging all power usage with a smart grid, so most stuff just turns off. A damn near worldwide grid with HVDC. Keep an entire grid worth of fossil fuel plants in reserve.

But in any case, it's not nearly as simple as matching wind MW for MW with coal, something which seems to get missed a lot, especially when discussing Germany.

(I feel like a broken record recommending this book all the time, but it really is fantastic for hackers interested in energy).

So, decades-long smear campaigns against nuclear successfully drive up costs, and lo-and-behold the author complains about the cost. The author also then goes on to ignore the externalities of solar, happily paid by the Chinese people on behalf of everyone else. The costs of refitting distribution infrastructure and whatnot are similarly handwaived.

I'm well aware that they're all just huge corporations going after their own interests. That's beside the point. You seemed to be commending Google on "taking the fight to the feds, hard", and I just wanted to point out that there's no reason to commend them.

> So why didn't they challenge it in 2009? Probably because there wasn't that much in it for Google, since wasn't a big national shitstorm blowing that way. But now there is. That is the point I am making.

Yes. I'm also well aware that corporations engage in damage control only when it's necessary. But again, there's no reason to commend them for doing precisely that, especially when that's all this is about.

>>> So, now, Google could serve their own corporate interests by fighting hard against the rise of the secret police. Would that make Google an awesome person? No, it would still be a selfish corporate entity trying to get money, just like it always has been
>>> But, it would (rightly) be perceived as a force for good, on the right side of this particular battle with tyranny. That would help you, me, America, and the world... but it would also help Google, it would seem.

Even in 2009, all those huge corporations were well aware of the "rise of the secret police", because all of them were either already participating in PRISM, or in the process of being strong-armed into doing so. Had they perceived fighting this kind of evil to be in their own self-interest, they would have done it right from the start. They could even have joined their forces in opposing the government, but they chose to remain silent. Not a word about the systematic raping of people's privacy all over the world.

PRISM was just as evil in 2009 as it is now, and taking a stand against evil was the right thing to do in 2009, just like it is now. Parading around as some kind of paragon of corporate virtue while secretly shitting all over your users' privacy, on the other hand, was something that only Google did. Also, if a highly intelligent bunch of people running a powerful corporation is interested in fighting the rise of the secret police, it'll be aware that's something that should be done right away instead of after waiting around for several years for the situation to get even worse.

Google can't be rightly seen as a "force for good", no matter how eagerly you swallowed their disingenuous PR-bullshit about the joys of being Open back in 2009.

>>> but once the outrage is in place, that helps align the interests of corporate behemoths like Google with what you and I would probably agree is Good (i.e., not having fucking secret police using secret laws to evade the control by the citizens of the nation).

It's important to realize that they've already proven they simply don't give a fuck. As long as they're making pleasantly massive piles of money and their armies of lawyers are keeping their taxes low, they're quite happy with the Status Quo. Don't think Google gives a fuck or even thinks it can change anything. Don't think it even wants to change anything.
