Another approach to understanding fourier transforms at the esteemed BetterExplained: http://betterexplained.com/articles/an-interactive-guide-to-...

This is more about the actual Fourier Transform operation itself, rather than the FFT algorithm. OTOH, it has whizzy interactive animations.

The thing that made it simpler to me was the fact that an FT takes us from an oscilloscope to a spectrum analyser and back again.
Did you ever get around to finish that? I'm curious.

I'm hoping to look at rsync in order to do partial changes, so I could synchronize VM disks and other large files.

I don't like keeping my PC turned on to perform a sync, so I would love to setup a Raspberry pi to do the work for me, but it only has USB 2.0...
People who do not understand technology seem to treat technology as a magic bullet that can be adapted to implement policy. It doesn't work that way.

You need to understand technology in order to understand the implications of what applying particular policy may lead to, and thus whether the policy itself is sane. In the real world, there are major implications when technology fails to implement policy because it fundamentally cannot do so.

For example: in the UK, David Cameron's attitude towards Internet censorship seems to be "It doesn't work. You're smart; make it work." and completely ignores the fact that it is technically impossible to do what he would like. Yet he continues to demand it anyway.

You have a time series of N points. You could use normal curve fitting to fit a constant function + (N-1) sine and cosine waves, and it turns out there is always a perfect fit, whatever your N points are. Discrete fourier transform is "just" a faster way to compute the same result.

Brilliant game! Loved the jingle .. it is going to be stuck in my head the whole day. What did you code it in (language, frameworks?)?
>when the real money – gold and silver – are used as an indicator.

The basis of your argument is wrong. An individual commodity like gold can't be used as indicator of economic levels. It is just as affected by supply and demand as any other commodity.

This is similar to when people try to compare the price of gas at the pump to the economy as a whole ("back when I was kid, gas was 10 cents a gallon, and now it's $3.50! Why aren't wages 35 times higher!").

Of course the panel is a joke but how many technologist put themselves in situations where they'd be in politics?
Apparently, money and power don't protect you from usual earthly human stuff.

Perhaps they are not as logical as you would think, and the woman in question is not as stupid or illogical as you would think (i.e. it's not just her looks).

How does logic dictates one shouldn't follow his/her heart, anyway? It's a tricky thing.

Let's say that I work at a bank and that the bank policy is to put all the money in the vault and as a result, the money will not be stolen. Then one day, the money is stolen.

Turns out that the reason the money was stolen is because the vault has no door. Just because the bank has a "money in the vault can't be stolen" policy on paper doesn't cause that vision of how the world SHOULD be to become REALITY. In order to winnow out the truth in this situation the review panel would need to have someone who knows something about security and vault construction on it. Also who perhaps would be allowed to inspect said vault to verify it's intact.

This is 100% analogous to the NSA review panel as all the folks in government are crowing about how it's policy that you can't look at such-and-such without a reason, but in fact there's no technological enforcement of said policy. Analysts can look at whatever they want provided that they give (type into a text field) some kind of ostensible reason, but that reason is only for auditing purposes. A bad reason typed into a field doesn't prevent the search as there's no review of said reason prior to the search running.

It's a bank vault with a door where the "lock" is a "sign in, sign out" sheet taped to the wall near the handle. And no security guard ensuring that people do in fact sign in and sign out. And definitely not checking to see that the money everyone's leaving with is in fact for the regular operations of the bank and not for their own personal gain.
Designing the World's First Floating City
I'm finding it hard to understand what you're saying because this is one big blob of text. Can you format it with paragraphs and bullet points?
I don't know any data scientists, or even what one is really, but here's the EE explanation: the Fourier transform maps a signal in the time domain to the frequency domain, and vice versa. So if you have a sine wave in the time domain [say something at 3khz: y = sin(3000x)], the Fourier transform would turn that into a pair of Dirac deltas (spikes that are infinitely thin but have an area of one) at omega = +-3000. Or, if you had a pulse, the Fourier transform would map that to a sinc [sinc(x) = sin(x)/x].

The Fourier transform is related to the Laplace transform, which maps signals in the time domain to those in the "S domain", a domain where locations are normally described with complex coordinates which contains information both on frequency of the periodic components of the signal as well as any transients (starting conditions, in layman's terms).
This is an interesting scenario. I've resolved this by running the entire build pipeline on wercker and only deploy the binary on Heroku by using the null buildpack. I'll write up a post on this in the coming days.

I think maybe I did a poor job of explaining myself.

Yes, I understand the things the tests provide. These kinds of tests have been around forever. Personally I don't like them, most engineers don't, but that's not going to make them go away.

My question was about the organization itself. Why measure something if you're not going to do anything with it? So in your example, where you're not motivated by money, but its a job that pays well and is boring, why find that out if you're not going to use it to disqualify someone?

The question in general is this: why measure something if there are no consequences to what you measure? I wasn't trying to say the test was great, I was asking the reason the test was given in the first place. The way I see it, it would have to be disqualifying in some cases. Otherwise, there's no reason for the measurement. Unless the goal is just to create a lot of arguing, which it seems to have done very well!

I think the problem is we like to wave our hands around and say "well, the test informs the decision, but is not definitive". This is just another way of saying that we don't know what we are doing -- there is no plan.

This is probably the root of the author's discomfort. Either he doesn't understand what's going on as far as the evaluation, or there's no reason for it, or both. Don't know. All I know is the guy was smart. That's also not enough information. Lots of smart folks in the world that I'd never want to work with.

This headline is borderline imbecile. The background explanation (which the author of this post seems to have skipped, for some reason): if you search "Jew" on Google, there's a small box (in one of the Ad-Word boxes) that contains a link to this page. The text underneath it is: "We're disturbed about these results as well. Please read our note here.‎"

Frankly, I think Google is the victim here. It looks a lot like what a large company has to do each time a bunch of crackpots take it upon themselves to represent the Hurt Feelings of Every Member of [their minority].

This is the sort of political correctness that makes me want to puke. This has to be the gem:

> So why is a search for “Jew” different? One reason is that the word “Jew” is often used in an anti-Semitic context.

You mean to tell me that people who hate people of Israeli ethnicity would actually use the word by which that ethnicity is named? I thought they just called them those-who-shall-not-be-named or something.

Of course some of the results of a search for "jew" will be anti-semitic, or will look anti-semitic at least for someone. Some people aren't smart enough, or interested enough, to understand that it's not Google's fault that some people don't like people of Jewish descent and choose to make their opinion public.

tl ; dr: Google doesn't seem to consider the word "Jew" to be offensive; Google looks like it tries to explain not-so-computer-literate users that the pages it indexes have nothing to do with their own opinions and options, just like it indexes both the pages that explain when abortion should be an option and the ABORTION IS CRIME crackpottery.

Unfortunately, it looks like the superficial and easily-inflamed are collateral damage here :-).

That's true for all kinds of efficiency, including automation, which is near and dear to the hearts of Hacker News readers.

The benefits of improved efficiency and automation, as you have pointed out, skip over employees. Some of them accrue to customers in the form of lower prices, but largely they accrue to management and shareholders in the form of increased profits. Costco appears to be the exception that proves the rule, here.

In theory, efficiency and automation should be a net benefit to society, as we can then enjoy the same level of goods produced with less labor involved, but the uneven distribution of benefits causes lots of avoidable suffering on the part of laid-off workers.

A guaranteed basic income for all (as opposed to means-tested benefits like welfare and the EITC) would fix a lot of that. It would remove the suffering from losing your job, and give investors an incentive to automate even more, as now you would have to pay people quite a bit to motivate them to accept low-skill menial jobs.

We can fund such a basic income in part by dismantling the welfare state bureaucracy. No means testing makes distribution much simpler. The rest through higher taxes on income beyond the basic.
