That's really awesome that you put that together, but I have to think that 200 points and a depth < 2 would basically be a linear search over about 100 elements right?

Fundamentally I can't think of any reason compiling a tree would be a good approach in a general sense.

Another optimization is to put make splits multiple levels instead of just one. How many might depend on how many you can squeeze into a cache line. If you split position is a float and the dimension is a byte, each split would be 5 bytes. You can squeeze 12 of these into a cache line. You can go 3 level down instead of one by packing 7 of them into a chunk (1 split + 2 splits + 4 splits). This still leaves room for a 32 bit index or pointer for each of the 4 leaves.
This. Hell, you'd probably sell a lot more by jacking up the price to 10x the cost of production/distribution instead of 3x and donating several purifiers to deserving communities for each one sold to the filthy rich.

On the other hand, this looks less like a common appliance purchase and more like a $10-20 thousand piece of capital equipment, so all bets are off.
If the $3600 is what goes into your pocket (I'm not really up on how SS is taxed, since I'm too young to ever have a chance of seeing a dime of it), then yeah, that is a pretty comfortable amount of income in many areas of the US. Assuming you have your mortgage paid off, there are a lot of places in the U.S. where a retired person with that kind of income would have more disposable income than anyone else in the community.
> Many coal and nuclear plants are actually quite good at load following (at least in France and Germany it's common to run nukes in this mode). The units are quite big so they don't have to do that many % per hour in order to keep up with a wind park.

It doesn't really make sense to do this with nuclear. Once you've paid the capital cost to construct a nuclear plant, the fuel cost is completely inconsequential and you might as well run it at 100% constantly. Even if you can vary the load you're better off to find something to use the extra capacity for than, essentially, throwing it away.

Of course, that's before politics and market inefficiency. It may be more profitable to reduce supply unnecessarily if it will raise the price per KWh because it's more profitable to generate 900MWh at $.18/KWh than 1000MWh at .04/KWh.
Trial and error exists, it's called 'genetic programming'
Modulo singularity fantasies, we have no hope of ever living in a world in which the old are just as healthy, active, and capable as the young because senescence is a function of entropy, which will always be a thing. The best we can hope for is to make senescence as brief possible, which probably leads to some dark places.

No, we just need to just accept and heroically deal with the fact that the poor will be with us always.
I always wanted to have clp, constraint logic solver facilities in regular languages.
But I wanted all variables to be symbolic when used in clp context, and then just assert and support for = with lhs functions needs to be added.
The trick is to find all symbolic variables involved by the compiler, but it's really trivial. cmbc does it e.g. for the C language. http://www.cprover.org/cbmc/

My plan is this:
http://perl11.org/cperl/perlcperl.html#clp

use clp;
sub fact(int $i=0) :int {
assert $i>=0; return $i ? fact($i-1) : 1 }
say fact(7); # => 5040
fact($_) = 5040; # solve it!
say $_; # => 7

Rosetta for example uses the typical simple LISP approach, by having to manually declare the symbols, which are being backtracked on. amb() is similar, expressing ambiguity. This goes back to 1963. http://community.schemewiki.org/?amb

Once you have electricity, you will soon discover two things. First that a thin conductor will be heated when you pass electricity through resistive heating, and secondly, that it will soon burn, melt or vaporize after a short time if you heat it enough to produce any significant amount of light.

In other words, the initial idea came from a quite basic fact about electricity, and Humphry Davy experimented with it already around 1800, but a lot of trial and failure had to be done before it could be used for practical lighting.

Edison did enough research to come up with a practical one. He was not the only one, and others, including Joseph Swan made practical light bulbs at about the same time. Even this seemingly revolutionary idea was really more trial and failure than anything else.
My advice for written exams is just memorize the basics (conditionals,loops,access control) and also to talk to whoever is grading the exam prior to you taking it. Often written exams will only deduct minor points for something an ide/compiler would pick up and knowing this walking into the exam can let you focus on things more important than syntax

I would highly recommend http://www.datomic.com as a database for multiple reasons, but one of them is that fact that it's totally portable between DynamoDB, PostgreSQL, MySQL, etc.

You can create a Datomic backup from any of these databases and restore them into a different one with the exact same semantics.
Median income of the subset of employed americans is only $2400/month before tax, so you'll be living better than most Americans at $3600/mo.

Why is us-east-1 so terrible? All of the downtime this year has been Virginia.
Yes, exactly. It's tempting to drink the Kool-Aid on the various services but the more you rely on them, the less flexible you become and more open to overall service failures like this one. You can take advantage of the benefits of EC2 without relying on the other services.

I mean, if even Netflix can't stay up during this, what hope does a startup have?

Not only is this particular pyramid scheme a relatively recent phenomenon in history, it's also only just now that the pyramid has burst, and we're now seeing the input to the scheme shrink - so it's now more of a diamond scheme, which isn't really tenable.

So I don't think this is something historically people have believed in youth and rejected in adulthood. It's only coming to a head now. Of course, it's reasonable to expect that the current entrants to the scheme will continue to try to perpetuate it once they've committed significant resources to it, despite complaining loudly about the scheme now, not least because many will have little choice (they will be in a worse place than prior entrants, having had to commit proportionally more resources prior to drawing their benefits, and generally be expected to receive fewer benefits when they do, as the schemes adapt to the situation).

What this rhetoric really boils down to, AFAICT, is trying to push some of that burden back up the pyramid earlier, so that the bust is perhaps shared a little more evenly. i.e. by reducing the benefits of current recipients so that they are more inline with what future recipients can be expected to receive. I suspect it is a fools errand, though, since these are typically legal obligations, so would need very controversial legislation to enact. I can't see "stealing from grannies" ever passing a democratic legislature.
Serendipity in the Digital Age
As an aside, it's sometimes really hard to get people to save for their retirement.

My employer recently had another round of meetings, trying to encourage people not to opt-out and extolling the benefits. At the moment, to put 1000 GBP into a pension pot will lower an employee's take-home here about 350 GBP - the company is doubling it (up to 5% of the salary), the government is giving the tax back, and the company is doing it by salary sacrifice so your take-home isn't so badly affected (tax etc. goes down a bit, offsetting a little the money the employee puts into the pension). They can choose what to put it in; stocks, funds, cash, treasuries. They can move it between providers, it's theirs. The only restriction is they can't have it back until they're at retirement age (not even retired; just at the right age, I think).

Even so, many people say they'll not bother, thanks. Some say they rather just save the money up themselves (costing them an incredible 1000 GBP for every 1000 GBP they save - three times the cost!). I know that putting it into a pension has risks and downsides, but given that the pension is basically tripling their money on day one, it seems incredible how many people aren't interested. Makes me fear that if people aren't interested even with (what seems to me) such a good deal, what are people without such sweeteners doing.
I'm all for digging deeper, but I'm not convinced you're going to find a satisfying answer. I try not to hop on the boomer hate train too much, but it's hard to look at what they were handed and not be angry. In the 60s and 70s, a college degree in anything from a decent school was enough to land you meaningful employment. That degree cost less than a third of what it does today. A decent size house in a metropolitan area could be had in your late 20s with a single income. Upward mobility in the workforce was basically unlimited, and thanks to the population bulge, boomers also were able to enact pretty much whatever political policies they wanted as an aggregate group.

Yes, Vietnam really sucked, and the S&L crash wasn't fun, either, but how hard would it really have been to set aside 5% of income every year instead of plowing it into ever bigger houses, more cars, vacations, etc.? I'll give you one thing - financial planning education in the US is absolutely awful and continues to fail millions of people every year. Without that, all you see is mass commercialization encouraging people to spend more money, and an ever increasing need to keep up with the Joneses.
As an AWS customer you need to be aware that the service health of all AWS services and not just the ones you use directly are important.

You say you don't use SQS or SNS? When they go down, you might not be able to get Logs or even login to the web Console.

Same goes for things like AutoScaling, OpsWorks, etc.
I would agree many posts are but I've had a few encounters with some of the people since some tend to comment on posts about them. If you interact with them they will search for your Twitter, Facebook accounts or guess your e-mail address it's like Hannibal Lecter is after you.

The few I have met are well-spoken and smart atypical Internet users not the usual riff raff but are just so oblivious of basic social skills.

S3 and VPC themselves appear to be fine, as noted on the dashboard, but the S3 VPC endpoints in EC2 are not ("we are also experiencing increased error rates accessing VPC endpoints for S3"). I was able to restore my sites by removing the endpoints from the routing tables.
I don't think there exists a coal plant in the developed world that isn't already using this technology. Without these particulate filters, a wide swath of area around each coal plant would be entirely uninhabitable by modern standards.
Yes, as it's shifting the blame away from their choice - which was to use AWS.
To be honest, I believe the trend is to only become worse.

Every generation appears to become more hedonist and think less about retirement. Many of my friends(millennials) make six figures and barely save any money for retirement.

Not related to the AWS outage, but Rackspace CDN customers are in for a world of hurt today as well.

AWS sign-in appears to be working but in general it's true that you need some sort of automatic failover. However, isn't that true for every option other than accepting downtime? It doesn't seem like an AWS-specific challenge other except at the implementation level.
In a glass bead you could set up with the data and like a lens, i.e. the data is small and when you shine light through it it projects the information at a wall. On the other hand spheres may have the problem that they roll away; and you always need another medium (like a box) to keep them together.

I think a big chunk of the low savings rate comes from skyrocketing college and healthcare costs combined with stagnant salaries for a long time.
Thanks. I was searching for it on the description page, but then rightly thought someone would surely post it on HN :).
Feynman had a useful tip - whenever you hear an "impressive" number, try adding a zero. Ask yourself if you would have felt differently about the statistic with the larger number.
Netflix -IS- up, and working fine. Pretty amazing, imho.
Well, last mile electricity distribution is almost aways an state sponsored monopoly, on top of a market that is naturally a monopoly.

I don't know how it could ever not be dysfunctional.
Hell you don't even have to live in flyover country. We pay $2,300 in Baltimore for a 2BR and the building has huge community areas and a pool. We get building residents together regularly for bbq, pizza, and pool parties.

I love NYC, but as the rents become more stratospheric and economic competition goes up, there is this odd effect where the people who can afford to live in a place big enough to host others are working way to much to actually host parties.
Define "enough". $3600/mo is $43.2k/yr, which is a few k/yr less than the nationwide median income. Keep in mind that in many areas, two wage-earners (that is, $100k+/yr) are required to maintain a middle class standard of living.

It could be pretty adequate if the potential retiree has planned well and has already paid off their home (a typical house payment in an area of the country with a sane cost of living would probably be between $1k-$1.5k). It'd really help to have some decently-sized retirement accounts.

Basically, $3600/mo is adequate maintenance money, but add one or two major expenses to that (like a house, car, or major medical bill), and it gets dicier. If you want to travel during your retirement, or do anything besides buy groceries, you'll need significant savings to draw from.
Simply showing up doesn't make one "provably dependable". One needs to actually carry out tasks, something the armed services are woefully inadequate at. Which is of course why all the contractors.

It's a terrible idea to mandate this. Horrible.
You could at least fall back to a read-only mode. That could be very helpful, compared to going down completely.

While it's blindingly obvious that the current monolithic pyramid schemes used to move money from the young to the old will have to disappear

I have some news for you - saving up now to pay for your retirement is also a transfer from young people to old people. The primary difference vs a tax and spend mechanism is that poor people suffer far more under a savings-based scheme, because they typically live hand to mouth and savings, if any, are for emergencies, not retirement.

Look at this way: if we're not going to euthanize old people, then they need to be supported somehow. In practical terms, that means a certain proportion of current production needs to be diverted to sustaining these old people. Whether this production is triggered by taxing or savings doesn't really make a difference to the physical distribution of stuff; a certain proportion of production will need to be diverted away from younger people and towards older people. It's either that or kill all the old people. And yes, this reduction in supply of stuff for younger people will also push up prices for younger people. In fact, the more savings older people have, the more expensive stuff is going to be for younger people in the future.

The primary benefit of the savings approach vs the taxing approach is that high-income people are much better off, and low-income people suffer far more. If that is indeed a benefit.
I save most of my income, and try to have a clear plan to spread spending evenly over my future, rather than just blowing money today (I'm 31).

At the same time, given the drastically worse quality of life from age 65+ relative to ages 30-60, I'm not particularly interested in plans that enable/force me to save a lot of money for that stage.

This isn't a simple case of hyberbolic discounting (overvaluing the present relative to the future)--I value those age 35-60 years quite highly and have been willing to sacrifice some immediate benefits to optimize them. I just think it's important to be realistic about the fact that certain periods of life are superior to others, and I'd rather stack my enjoyment in those periods.
I really love the feedback in the demo as to what the recognizer is guessing. If my Palm had that I believe I might have been even faster at writing graffiti. It allows you to quickly correct a "letterform" to get the desired glyph.
Netflix is down.
Same way you learn anything else: repetition. Practice, practice, practice, practice, practice.

You'll probably have to make some judgment calls about what's worth keeping in that cognitive space, though. For commands you use all the time, you should know the syntax without even thinking about it. For things you use only rarely, it's a better use of your time to just look it up. If you use it semi-regularly, look it up, bookmark it, and eventually you'll just memorize it.
I live in an area where $3600/month is more than the median income.

Hell, five years ago, I was supporting myself, my wife and a kid on about something like that.[1] It was rough, but just barely manageable.

[1] "Something like that" because I was making significantly less, but had some familial advantages (I was driving a car in decent condition that I got from parents when I was younger, parents bought the kids lots of clothes, and of course I had a safety net, which is huge--not having that would've moved me from constant stress to full blown panic).

Edit: Ohhhh, I forgot the EITC, which makes a big difference. That nudged us a lot closer to that line back then.

Still, where I live, $3600 a month would be fine for a single person who didn't have enormous health care costs (and I know that's a real "aside from that, Mrs. Lincoln?" comment. Retirees are pretty likely to have big medical bills).
The pension funds have lost a lot of trust, and that's not the fault of the employees.
Indians and Chinese save 20-30% of income. They do it by consuming vastly less than Americans. Americans simply view cutting consumption as unthinkable.
Wouldn't insurance be a better response?

I don't know, how google did it, but the first result for exactly the query of yours is: http://awesome.naquadah.org/wiki/Beautiful

What surprises me, is that it works in firefox private mode, where neither of search customizations should work, in theory (fresh clean cookies and local storage, isn't it?). However, yeah, I do indeed google awesome-related stuff from time to time.

UPD #2: it works from different browser and different IP either. So it seems that you example is not relevant anymore :)
"Carpe diem is failing on people."

This is quite funny when you think that "Carpe Diem" originally means literally the opposite of what people use it for nowadays.

The original quote is "carpe diem, quam minimum credula postero" i.e. "Seize the day, put very little trust in tomorrow (the future)". Meaning that one should do everything today to ensure a good future and be prepared.
Why would you run a "critical payment application" in US East? This datacenter has 10x the downtime of West or Ireland.
us-east-1 is where they typically deploy new features/hardware first (with the exception of efs which went to us-west first for some reason). it's also by far the largest region, with the most tenants and the heaviest traffic, so it's approaching the limit on what's physically possible to do in a public data center.
Storage/scalability must be solved before doing the complex analysis, through, and is the primary bottleneck.
Browsing through the source, Quest also seems to be a really excellent example of Literate Programming.
"Median income of the subset of employed americans is only $2400/month"

That's also a good point as to why people aren't saving money....
Where are you seeing that $28k/yr is the median income? Bear in mind this is per month, not per pay period.
It's the primary AWS region. You spin up your resources by default there unless you explicitly select another region in the console.
Reducing the number of someones you trust is good. I think the only difference in our approach is what others are trusted to do. In your model, some are trusted to send new code to users. In my model, new code must be acknowledged first, before users can consume it.

I don't think one approach is necessarily worse, but one can provide all of the essential functions of the other, without allowing unseen code to be pushed to users.
Do you mean actual syntax, like how to define and call classes, methods, variables, loops, if-thens, etc? Or API definitions, like the standard classes, the methods available on them, what classes they return and what you can do with those classes, the best-practice way to do various things?

You should have a pretty good handle on the syntax after a week or two writing original code in that language. And other languages get easier after you learn the first one or two pretty well. But that's the easy part.

The hard part is the API definitions. Most good languages/frameworks have such massive standard libraries and sets of common add-ons that very few people can be certain of the details of more than a small portion off the top of their heads. You tend to memorize a good bit after working on it for an extended amount of time, but Google and autocomplete will always be your friends.

But for any school-type tests on programming, you'll want to pay close attention to exactly how they're grading. That may tell you a lot about what you need to do.
A lot of those criminals were people who were transported for trifling offenses like theft. The real driver behind Australian settlement was overpopulation in Britain, not the need to get rid of some hardened criminal class. The Fatal Shore is a good, readable history of this social experiment.

Note also that this "budding free society" was responsible for horrible atrocities against the native population until fairly recent times.
