Start with different people talking all at once - some loudly, some softly. We can try and make out what someone is saying, but it's not easy. So we put each person on a different radio station & we then 'tune' our radio with a little knob and dial.

If our ears could hear radio frequencies - like AM1070 - then each station by itself would sound like a dull drone or a tuning fork. It's dull because it's repetitive - it sounds the same this second as it sounded the previous one. To make the drone interesting we multiply it with a person's voice signal (say from a microphone or rolling tape) - then the drone kind of goes wah-wuh-wuh-wah, and this 'modulated' signal is a lot more interesting.

That's basically the Fourier transform - a sum of Speech.Station signals, where Speech is interesting and Station is repetitive.

---

We can play this same game with the speech itself - or music. Think of each note do-re-mi-... as radio stations, and the pressure applied to each key of the piano as the speech. So, music can be represented by a combination of the form KeyPressure.MusicalNote. The KeyPressure sequence can be recorded in a music sheet. The notes themselves are boring (as the kids say in The Sound of Music, the notes don't mean anything), it's the "multiplication and sum" with the KeyPressure sequence that makes music.

Again, note the summation overy x.y terms, where x is interesting and y is repetitive - that's the Fourier transform.

Historical sidelight:
The simplest sheet music is Morse code, dah-dit. When telegraph became a booming business there was a shortage of wires to handle the volume of messages. People wanted a way to send more Morse per wire. Alexander Graham Bell had a bright idea - this was a few decades before radio - he took several Morse streams & put each dit-dah-dah-dit-dah sequence onto separate notes (like do-re-mi), and then sent the lot down a single wire. As he played with his system he had the deep insight that if the Morse code was replaced by sheet notation, then he could transmit music down a wire - and that became the telephone!
Apparently historically many of the rules came about during the early 20th century US oil boom. Guys used to go door to door selling shares in can't go wrong oil stocks and then not only did some wells not work but often there were no wells at all and the insiders just stole the money. There was political outcry so laws were passed to stop selling direct to small investors. The rational to allowing wealthy investors to punt is that a) they can afford to lose, or at least do so quietly without causing a political stink, and b) can afford professional advice and get their accountant to have a look and so on. Investor protection laws are still useful - there are plenty of scammers out there - but I think could be updated. For example the government could have lawyers and accountants at least check out the money was being invested in a business and not just paid out to the insiders. In the UK we have some equity crowd funding which seems to kind of work.

I can also agree that your reasoning is correct that a spherical rooster you modeled will roll off the roof. Doesn't mean you're right to argue that roosters can't stand on roofs.

Would my reply have been more useful if it did not acknowledge you have some reasonable points and instead just ignored anything you had said as you apparently feel is the appropriate way to frame this discussion. If that's the case I would expect it's safer to dismiss your view than someone's who does not subscribe to that particular philosophy.

More to the point I agree with your quote:

>> I agree with your reasoning ... (some stuff) ...

>Awesome.

>Let's boycott and protest everyone who does ... (some stuff) ...
I think a lot, probably most companies on Kickstarter would be ok giving 10% of equity to their backers if it was legal.

> The reason for this is that if you're doing IO in Java you'll usually use some kind of buffered input reader rather than stdio.

The methods are the same with a buffered input reader.

> I've written a command line in Java that reads commands, runs native commands, streams output to the console and even that doesn't need to read stdio as a stream.

So, the thing that you are struggling with is how to get to System.in? But no problem doing System.out?

That's not even what the various code samples that have been posted have failed.

> It's not that Java can't do that, it's that there are better idioms for most problems.

Java's actually very good at doing IO efficiently, and as has been demonstrated, the code for this is quite simple. Sure, you wouldn't implement "cat" in Java, but you would read and write to sockets & files with it, which provides all the knowledge one might need to figure out how to solve this. As has been pointed out, the Apache Commons libraries make it so this is a two line program with no branching or looping. That's about as simple as it gets.
Yikes. "Fuck you, Palmer." What the fuck? Folks, this is why creators on the internet have public meltdowns and abandon their communities and/or projects. (See: Phil Fish, TotalBiscuit, and many others.) Simply despicable how these so-called "fans", who have no idea how to run a multi-million-dollar business, can turn on a dime and start slinging vitriol at the person they claimed to idolize just a day earlier. How about, you know, giving the fucking guy the benefit of the doubt? You know, just for a bit, instead of tearing his fucking throat out?

The older I grow, the more I feel that people need "internet cards" that can be forcibly revoked until they at least develop a base amount of empathy.
Kickstarter is not charity. The people/businesses that raise money on kickstarter use the funds as an income stream. They're selling their brand and you're buying good feelings. It's a source of income for them. It's a product, an intangible one.

Prohibiting same sex marriage is the government asserting that it is not possible for two people of the same sex to love one another, by any definition that would allow them to be considered legally "family", and that is definitely not equality.

No doesn't work like that. Raising funds is raising funds whether it's in us$, bitcoin, pork-belly futures or whatever. You could list in another country like on Seedrs in the UK and then presumably be subject to UK rather than US law. Although if most of the investors and assets were in the US the SEC might still try to stop it.

That's because investors think about short-term profits, not about world-changing technologies.
I don't understand this logic -- simply being a part of a successful public company reduces your opportunities or chances of making a splash? That's preposterous.

Yes, there are checks and balances -- however I am hard to believe that essentially working as their own team with some layers below Zuck offsets the significant resource investment that oculus didn't have before.
> This solution (and whatever solution you might have in mind) likely both dont solve all sorts of problems. for instance what if there is a power failure and you lose all the output? is it persisting to disk? what if new input methods that arent even thought of it come to exist 5 years from now, is it compatible with that?

You are missing the point. The code doesn't work. I'd love to hear any interpretation of the problem where that code actually is correct.

> A lot of investors and enthusiasts saw Sony’s Morpheus as a potential Rift killer.

So this is going to be an expensive additional add-on for the PS4, that would somehow have killed the Rift? Optional console add-ons rarely gain any traction, and while Sony made a great demo unit, they have plenty of money to make powerful, fancy prototypes. There's no way of knowing what the actual consumer units will be like until they actually create a product out of it.

Oculus started basic and is improving because that's all they could afford to do, given their need to release actual usable, mass produced hardware to backers. Sony started huge, and now they'll see how they can distill that down to a mass-producible item. And that probably won't be for a year or two.

So yeah, they have competition now, but Oculus did not sell because they were afraid of a shiny demo. It's not a product yet, and there's no guarantee that it ever will be.

Recompile away, stuff just works. Add lambdas to your code, compile. Still works. This isn't like 1.2 where you were adding collections classes (arguably for the first time) or 1.5 where you encounter generics.
CIA operative thinks Big Brother is 'not so bad after all'.

It's like the final paragraph of Orwell's 1984:

"He gazed up at the enormous face. Forty years it had taken him to learn what kind of smile was hidden beneath the dark moustache. O cruel, needless misunderstanding! O stubborn, self-willed exile from the loving breast! Two gin-scented tears trickled down the sides of his nose. But it was all right, everything was all right, the struggle was finished. He had won the victory over himself. He loved Big Brother."

> Everybody wins in this deal -- except the people who donated to the Kickstarter. Those folks... well, they kind of end up looking like suckers.

It's kinda a twist to the normal Kickstarter warnings—if you back a product, it might not ever succeed, jut disappear. This was a product that people backed, that was too successful, and looks like it's about to disappear.
> What if Big Brother isn’t so bad after all?

But what if it is? Try putting that genie back in the bottle. What about the surveillance regimes of the past, like the Stasi? They were such successes that we should use the modern technology we have today to add to the powers of the elite?

Right.
Actually, the dude (heavily) edited his original post after a bunch of people pointed out that he didn't know what he was talking about.
> Google employees are usually smart, this person isn't.

I don't mean to sound crass, but if Google employees are so smart why is Google so collectively bad at doing anything right for an end user experience? Adwords does awesome, Google X has a mind of its own, but the rest of Google? The only thing somewhat decent that comes to mind is Calendar, Gmail, and the latest versions of Android.

Mind you, I'm a huge Google fan, but it (as an org) makes some pretty terrible decisions collectively.
This is really cool!

Initially, I tried using this between a computer on my 2.4 GHz band and a computer on my 5 GHz band, and I guess the JavaScript wasn't able to determine the local IP addresses. However, after switching to the same frequency it worked.
From https://coreos.com: CoreOS enables warehouse-scale computing on top of a minimal, modern operating system. The strategies and architectures that form the building blocks of CoreOS have been proven at companies like Google, Facebook and Twitter.

Show HN: Automatic albums recognition for iPhone
‎I'm glad I got to read this post since I recently didn't get into HS for this summer.

I don't think I'm worried that they may have made a mistake with my application because I'm worth the time, or other self affirming points (blah blah blah). Although, it would have been nice if they mentioned what exactly made them feel like I wasn't a good fit so I could work on that. I get that it's not always possible since they probably get a huge number of applications to go through.

It seems like they do a lot of introspection which I like to see - gives you a sense of what kind of people they are and makes me want to go there even more.

EDIT: Grammar
I'm surprised to not see AirPair in this roundup, they're very well situated in what could become a huge industry.
No, it is factually true. JC on Twitter: "I have a deep respect for the technical scale that FB operates at. The cyberspace we want for VR will be at this scale."

HN is a profoundly conservative community. It's not always obvious, but the horizon here is often very close.
Carmack wants to build the Metaverse. Facebook wants to own the Metaverse. I don't see this as a good thing.
Yahoo turned down a deal with Google when the company was still young. But if you imagine, what would happen if the deal went through? Would self driving cars, and glass be a thing today?

It doesn't really matter. MS has plenty of new patents they could use to tie you up in the court system for years. Fighting that would probably bankrupt you.
Yes, but exponentially moreso when he becomes the public face of the company and (to some degree) the arbiter of its corporate culture.

A basic human right--one much less arguable than some idea of state-granted civil union--is to have one's actions and words weighed thoughtfully.

Throwing the technical leadership of Eich out over what amounts to a difference of opinion (on perhaps an important matter) is rubbish.

Marriage is a societal compact, and as such is a product of the community in which you live. We, somewhat luckily, live in community where we can vote to establish norms. There is nothing wrong with having somebody else in the community vote or contribute with an opinion different than yours, because that is how the community comes to a consensus about its societal norms.
Virtual reality has existed for thousands of years.

It began with performed and written stories. When storytelling through film became popular in the 20th century, proponents marveled at its technical potential: the ability to control viewers' eyes and to immerse them in a dream world. There were also critics who suggested it might be too immersive: detracting from face-to-face conversations.

Over time the technical "Wow" factor of film mostly faded. In its absence, viewers started to remember what made virtual reality feel real all along: the quality of the content. Sure, some people still marvel at 3D screenings and similar technology, but we mostly focus on the narratives rather than the medium.

If history is any guide, there is no medium for virtual reality. After the initial "Wow" factor of a new viewing experience subsides, we'll realize that the content is responsible for carrying us into a dream world.

Personally, I think this illustrates a severe gap in how crowd-funding works.

10K drops by an individual are no different than an angel investor.

There should be a chip-in-level for crowd-funding campaigns that require the OP to provide some % equity into the project.
OK, I'm often a bit skeptical about some of the startups from Y Combinator, but Airhelp is definitely something interesting for me. Anything that simplifies going after relatively small sums of money is good in my book.

Hate to break it to you buddy, but calls that are lead by the Director of Investor Relations are fluff meant for public consumption, and thereby not "internal" at all.
Sad that Google will sink to doing business with Luxottica over some awesome company like Warby Parker. I have no interest anymore.
Yay! Now I can have a unit for $70... so long as I finally sign up to Facebook to be able to use it!

Actually, I'm surprised that Apple didn't get to Oculus. Apple has a history of being a catalyst in markets that are not yet matured. They did it with the iPod, iPhone, and iPad. All of them were preceded by plenty of products that perhaps looked very similar on paper, but were a completely different (clunky) experience to use until Apple showed the market how it's done.

Oculus might've been what the Macs needed in order to take gaming market-share from PCs. Missed opportunity for Apple. In my opinion, would've been a bargain for them at $2B.
exactly. FB has experience with stuffing LOLCat pics in your FB feed. Not innovative tech.
If Oculus's plan all along was to create a giant MMO powered by Rift headsets, then this is the first I've heard of it. Interesting. I think a bunch of smaller apps created by developers has a better chance of being successful.

EDIT: By "giant MMO" I mean "metaverse from Snowcrash," not "video game."
A better analogy - fans pay an artist up front to record an album, said artist then uses the resulting success to produce a different genre of music for a major label under an exclusive contract.

Fyodor's a mensch, but I think he's romanticizing the concept of Full-Disclosure and that he's ultimately going to be unhappy he tried to keep the list alive. Sometimes dead is better.

I'm not clear on why a mailing list like F-D is in any way better than a subreddit or an instance of Lobsters.

Proponents of the mailing list say that the list is decentralized and allows everyone to archive its contents. The list is not in fact decentralized, and a message board also allows for archiving. The boards don't do this by default, but that's a good thing.

Message boards also offer a better reading experience. A lot of F-D is dreck. A threaded view (maybe with voting, maybe with collapsible threads) is the only sane way to view it. Boards also offer search.

People wonder why I post so much on HN. It really has nothing to do with HN; it's that HN replaced Usenet (and blogging and IRC, but mostly Usenet). I now grudgingly admit that web-based message boards are better than Usenet. The relationship between Usenet and mailing lists was once deep and productive. Maybe message boards should replace lists (at least, big public lists) as well.
From mid-2013 after Series A investment:

'Also, the plan is still to stay an independent company... not sell to a big fish like Sony, the way Iribe's former employer Gaikai did last June. "We want to stay independent and get to the consumer market, realizing VR the way we really think it needs to be done, and we don't need to take any shortcuts to get there," declares Iribe, adding that his new venture capital bosses are on board with that.'
You sure about that? https://news.ycombinator.com/item?id=7053239
Fair point, I forgot about the lack of eyes part. I guess the Oculus Rift would work better for a multiplayer FPS where your characters are all wearing helmets.
Maybe that new comment system was a good idea after all.
when they're "investing" in something like Kickstarter they're not actually "investing" in the general sense

I'd say they are only investing in the general sense, but not the specific one. Because, as we've seen with the Kickstarter failures and flake-outs, regardless of the HN-conventional definition of the word, the donors are certainly and legitimately invested.
Yah zuckerberg clearly reading off a script, and there was a huge disclaimer that is a hallmark of a public facing conference call. not internal at all.
So perhaps the answer is for Kickstarter to not allow any sort of companies to be funded, but rather only keep it for once off art projects...
at this point, we should read "hiring like crazy" as "trying to get acquired". Having a lot of employees boosts your valuation but does little for your ability to deliver a product
Maybe it's the AAA developers that are worth all the money and not the rest? Maybe their Series A and B investors changed their mind about looming threats and were keen to get cash fast?

Also, remember that Valve's technology is apparently excellent and they also have the ear of developers.

Which is the point, the IRS doesn't want barter to be normalised because that would mean some people could claim barter and escape paying tax.
