A double can store every integer from -2^53 to 2^53, which seems sufficient to do financial work.

2^53 is 9,007,199,254,740,992

If you want to denote that the last three digits are for fractional dollars (i.e. each integer represents 1/10th of a penny) then you can store any monetary value from -$9 trillion to $9 trillion.

EDIT: Note that it's tempting to think that you can skip converting decimal currency to integer as long as you only use <= 3 digits after the decimal and you're storing values of less than 9 trillion, i.e. it's tempting to think you're safe storing a value like $1,283.212 directly in a double without converting to integer. But I'm pretty sure that's mistaken. You always need to convert to integer so that you're storing 1,283,282 in a double, not $1,283.212

The reason is because certain decimal values which can be represented in base 10 can't be represented in base 2. For example, $0.1 can't be stored into a double as-is; if you try to store 0.1 into a double, you'll get:

0.1000000000000000055511...

which is where the inaccuracies can start to come into play. Whereas if you convert $0.1 to integer, you'll be storing the value 100 into a double, which comes out to exactly 100 without any error.

Of course, the error may be so small as to be insignificant, but the point is, I'm absolutely certain that integers between -2^53 and 2^53 can be perfectly represented by doubles, but I'm not certain that <= 3 digits of decimal precision can always be accurately represented by doubles for values of less than 9 trillion.

EDIT2: You have to be careful when converting between currencies, too. For example, right now $2 = 204 yen. If you're storing yen, 2^53 yen is different from 2^53 one-tenth-pennies, so the max value that you can store is specific to each currency. This seems like potentially a tricky problem, and may be what the parent commenter was referring to when saying doubles aren't so good for financial work. Still, though, 2^53 integers of precision may be sufficient regardless of which currency you're using.

Having trouble loading first article, as it just shows a headline [edit typo] but thank you for the citation, I'll take it with a grain of salt.

You're being misleading with your second article, however.

> If you removed the ITC (a federal tax credit for solar), the cost would probably be about 8¢/kWh. Still, that’s not bad.

It's a good start, but still not nearly "grid scale cost", and you're only getting electricity at that price when the sun is out. Not suitable for base-load generation, but for peaking. Useful, but not 100% availability useful.

Re: Natural gas - it depends. Prices fluctuate, so it goes both ways. There have been times where gas was much cheaper than many options, only to become a very expensive choice because prices went up. Imagine how the plant owners feel when they build a facility while prices are at one level, only to have to operate it at a higher price later!

The flexibility that combustion turbine plants bring to the grid, however, make them good choices as they have short startup times, work well as spinning reserves, and these days aren't too expensive to operate. When the fuel comes from within our borders, it is good for national security, too.

A bigger thing hurting greener competitors is bad information and idealistic proposals that do not have practical engineering foundations. I'm still making my way through the paper, but I'm incredibly skeptical these guys really understand the grid (grid grid grid) and how it's really put together.

Remember, the goal behind the grid is to provide very reliable power to customers at a decent price, and operate the utility at a profit. Consumers don't usually care where their energy comes from, but obviously "feel better" if it's from environmentally friendly sources. The "early adopters" among us might go for higher prices for cleaner energy, but no "mass market" consumer is going to accept lower grid reliability in exchange for a greener power supply or comparatively higher prices for a "greener" one.

Why does a per-capita number make any sense here?
Java has a very good sand-boxing mechanism (AcessController), which helps limit the effect of bugs in libraries. Firstly, the memory model is highly abstract; no pointer arithmetic and type-less references. To mess with the memory, the thread needs to drop down to native code, and this where sandboxing can trap this behavior.

The same mechanism can also help increase trust in a third-party library from a security point of view. Every access to a file or network resource, for example, is checked before being granted.

I do believe the etymology in this case lies with Old English 'domes dæg' which was thought to be some apocalypse 6,000 years after creation, which was thought to be ca. 5,200BCE.

> My brother is just a 6' and considerably smaller than I am.

That is already very large, please don't interpret this as a sign that your brother is less healthy than you. If you are considerably larger than 182cm, then by some measures you'd be viewed as being less healthy than your siblings because you're prone to all the problems large people have.

It is very likely you all three maxed out the size range available to you genetically and epigenetically by receiving adequate nourishment, as is common in industrial nations.

> Might there be a biological imperative to ensure that the first born is healthy

Probably not as such, but the psychological effect you're describing might create that impression: first-time parents obsess about everything because they don't want to make any mistakes. With subsequent children they realize they've been overthinking everything and they consciously apply what they learned the first time, instead of indiscriminately following through on every little thing that comes to their minds (like giving up soda).

It's also a very first-world way of thinking about children.

> Then with the later children parent lose the need to ensure their children are as healthy.

Again, I think you're postulating purpose where none exists, because you see a correlation between your "better" health and the amount of attention your mom applied to arbitrary details when she was carrying you to term.

Instead, evidence suggests that increased survival pressure in humans leads to an increase in the amount of children a couple has, and attention to individual children (including first born) goes down drastically.

My own anecdotal impressions of wealthy industrial societies imply that while first-time parents sweat arbitrary details, it's really the last child a couple has that receives special attention. Partly because the parents have better skills, but probably also because they know it's the last chance "to do everything right".
it doesn't do RS to MJ: no use to me XD
I'd like to take a moment to point out another really great "renewable" technology that is a clever arbitrage hack using power prices: Compressed Air Energy Storage. (http://en.wikipedia.org/wiki/CAES)

To me, this is "Grid 2.0" technology. You are moving energy from times where you have cheap excess and placing it on the grid in times of expensive need. If we are going to move to a grid with a lot of renewables, technologies like CAES and pumped hydro (https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricit...) are two necessary ingredients.

The primary difference between CAES and pumped hydro is that CAES is cost effective for both medium (50+MW) and large (500+MW) installations, while pumped hydro is cost effective only at large scale (500MW+) installations.
the TV remote example given is why Google TV flopped and Apple TV sells well

Google TV was trying to do something entirely different from Apple TV. The former was about adding intelligence to cable (which is an enormous issue because there are many players you have to work with, and most are hostile and protective), the latter a relatively typical media box.

And FWIW, I absolutely despise the AppleTV remote. It is brutal to do anything beyond simple navigations, and even that is far less effective than it should be. Add that it has one of the most unforgiving, unidirectional IR emitters ever: I was shocked to find that Apple didn't go wireless for that.

It is unfortunate that the Apple apps for this -- using devices as remotes -- are so horribly terrible.
Yup, it's just cultural inertia. You are trying to understand the situation's economics from a capitalist point of view, that the brides are "worth" something, and the investment the parents have put into their upbringing was "value" the bride's family put into the marriage, and they should be paid for that.

However, in the culture of India, the groom's family is doing the bride's family a favor by taking the bride off their hands, and undertaking caring for her for the rest of her life. Thus the bride family pays for this service. Usually the dowry is proportional to things like how undesirable the girl may be, how desirable the guy may be, the difference in social status between the parents, all favoring the guy.

Of course, the family itself thinks more along your lines -- "I have to spend money to raise her and take care of her, and then I have to spend an exorbitant amount more when she gets married as dowry," and thus end up resenting her existence from birth.

It's pretty silly, and is slowly fading away, but cultural inertia in a country as large and riveted in its ways as India is a force to be reckoned with.

OK then it's a terminological confusion, because I would say that gives you a dependency on said "dynamic link libraries". Whether you need to write a C/C++ wrapper only determines if the dependency is in runtime or also compile time.

This was their first source release, before the GPL was widely known, so that's why they used this specific license.
I wish I could find the PDF from a research group on the topic of CAES. Their thesis is that we could generate most of the USA's power by installing solar in the south west. The power would get pushed to the rest of the US and stored in CAES repositories using natural caves. Each cave system should provide 3 days of sustained use for its region. This would allow for power disruptions. I can't recall if they also included natural gas as a fallback incase of protracted outage.

It does open us up to a single point of attack, but I thought it was an interesting idea.

I'm seeing a lot of misinformation on this thread, and I think it would be useful to point hacker news at the Electric Power Research Institute (EPRI), which is a cited source in this paper. They are an engineering-based, independent, non-profit research company. And their headquarters is in the "heart" of Silicon Valley next to Xerox...

http://www.epri.com/

Full disclosure: I am not an EPRI employee, but I've read a lot of their papers and presentations. Their research is original and unbaised. Their engineering is pragmatic and chocked full of raw 100% reality. I wish some of the websites people are citing here were talking to places like EPRI first, but instead write sensationalist headlines that hide details and misinform, making sane, coordinated discussion difficult.

I suggest hacker news check them out and maybe send some emails to get better information about this proposal and learn more how the grid truly functions politically, economically, and technically.

From the demographics, it's quite clear that SV has no problem with non-whites. And if you compare the graduation demographics in technical disciplines with hiring demographics, you'll see that all groups are fairly represented.

If certain groups of non-whites are not receiving the education required to contribute in SV, that isn't the responsibility of SV to fix. That's the job of the government and the schools. And it's on the communities where those underrepresented minorities grow up to change their toxic cultures so they don't look down on being educated as "acting white."

I was thinking about that in response as well; then I began to wonder. Is it that the quality is actual higher, or that I'm more likely to gravitate towards established, well-tested libraries (of which there are fewer in javascript)?

The more I think about it, the more I think it's the latter. There are tons of crap libraries out there for any language - but the more mature languages/ecosystems naturally tend to have a wider selection of more mature libraries.

You know why you lost the lottery? Because Indian outsourcing firms like Infosys, Wipro flooded it with applications to bring in cheap labor!

They also bring an incredibly bad name to the rest of the Indian developer community.

Yes, you're right, numbers treatment is not exactly the same as in Bitcoin Core. The script interpreter supports only basics and it was implemented to show how Bitcoin Script works in general for another article [0].

Yes, rational thinking dictates exactly this conclusion (the apparent randomness being introduced by our current understanding of quantum physics).

Well, Rome wasn't built in one day. Our whole culture was built upon the illusion of "free will" (same goes for other beliefs like magic, gods, etc). It's a good exercise to remind oneself about this when we get all worked up over something or somebody.
