I must say I get rather irritated when people spend time worrying about dubious 'tweaker' methods to improve their audio, when the most under-performing component of most people's sound equipment also has the lowest-hanging fruit: The room itself.

When people ask me where they should spend money to improve the quality of their hi-fi or home theater system, in nearly every case my response will be something like "get a thicker rug" or "put something on this wall to absorb sound reflections, even if it's just a bookshelf."

Beyond that, I'd tend to say something like "stop being so paranoid about what you think you can't hear, and enjoy the damn music."

I'd say that the article is criticizing the ability of democracy to deliver the latter, and that in a representative system the two can't be neatly separated.

If the system in aggregate produces candidates who can't execute what the people want, but yet each individual determines their own choice of vote amongst the poor choices, can this really be said to be self-determination?
I'm using localstorage to remember settings that used to be stored in cookies. These are things like the collapsed state of a panel, the dimensions of a popup window, and the most recently used values of a location picker. It works really well for that.

I think people run into problems when they store megabytes instead of kilobytes. Localstorage is essentially cookie storage without the networking dependency. Treat it like that and it works well.
If it where me I would go the other way and have the expensive dev lay out a modular architecture and then outsource the modules. Getting the architecture and isolation right is 90% of getting an app right because if code is properly isolated and a module is bad, it can be rebuilt without having to touch the larger system.

I used to work in the Notional Weather Center in Norman, OK. I assure you, you're not the only one who's worked on this, or had the idea :)

Having worked on projects with granular geo and weather data before, make sure you validate your monetezation strategy with this early and often. You'd be surprised at how little big weather firms and "typical" weather data users don't care about the specificity and accuracy you provide. But, you'd also be surprised that there's a lot of valuable niches for weather data that you wouldn't normally pursue.
Yes, though I tend to think of the reconstruction filters as being part of the recording format.

Here's an interesting article:

http://news.google.com/newspapers?id=E5guAAAAIBAJ&sjid=d6EFAAAAIBAJ&pg=3183%2C2664048

In 1975, the Canadian Broadcasting Corporation was using a head shaped microphone, which was presumably an attempt to reproduce the non-linearity of the ear. It would be interesting to do such experiments with digital sampling.

Thinking about it, if every person has a different non-linear response, in theory the only way to reproduce sound beyond a certain threshold of fidelity would be to reproduce the ultrasonic components, so each person would hear their own non-linearity. (That would be beyond what I can hear or care about, but it would be fun to play with. Beyond a certain level we also get to the point where we need to ask what it means to hear a sound.)

Harmonics in real-world instruments are not usually exact multiples of the fundamental. A simple diffeq model of a rigid oscillator will show you this mathematically.

That is absolutely incorrect, mathematically speaking, harmonics are by definition "integral multiples of the fundamental." (Fundamentals of Acoustics, Kinsler & Frey).
The hearing of ears is a time-domain thing, not a frequency domain thing. It's the frequency response of all the frequency components added together. people might not be able to respond well to a single high frequency tone, but might respond well to a combination of tones.

I left Yahoo three weeks ago to do my own thing. There are lots of talented people at Yahoo - there are not too many companies which deal with the kind of scale and tech Yahoo does and a lot of people like that. Some of them have been there for over a decade. What is happening to the company is very sad.
Considering it takes years to design a CPU I don't think it would be worth it. The point of software is that you can change it quickly and so it evolves faster then the hardware that runs it.

IMO that's an advantage that easily overcomes any instability that new software brings.

That said there was an interesting article/interview (cant find it sorry maybe someone else can) with one of the creators of hotmail. Off the top of my head he said that because he came from the hardware side when creating the hotmail software it never broke due to the processes and practices he followed. Perhaps there is a middle ground that we can take and get benefits all around.
That would suppose that the recording device precisely matched the orientation of the listener, and the recording was not created digitally in (multi-track fashion for example). There would have to be air space in order for the interference pattern to set up in.

So you'd be right if your mics were head spaced and in the venue. But you'd still have secondary data, with the original lost.

Amen. Someone got the point of the article.
> And when your oscillator is no longer one-dimensional, most harmonics aren't even close to integer multiples. The harmonics of bells, cymbals and drums are all over the place. That's what gives them their percussive sound.

But those aren't harmonics, they're inharmonic partials.

I've had an account here for more than four years, so I'd like to think I have a somewhat informed perspective on how the community has fared thus far.

The first year or so was a private club. I knew many of the posters, and would have great arguments, some won, some lost but it didn't really matter because everyone shared a passion for knowledge, and would rather be proven wrong than not learn something new. The discussion was great.

The second year I started losing track of the usernames and thus it became less of a club of peers, and more of a regular forum, albeit a very high quality one.

The third year the site had attracted so many users that the original patos of intelligent discussion based on merit started to fade. Based on mere numbers this had to be so; for any given subject there are only a limited number of people that adhere to the standards to which we had becomme accustomed, and new users mistook nitpicking for good discussion.

The fourth year I've more or less stopped posting and discussing here, primarily because it's become a game of winning, and not a game of learning. Nitpicking is a great way of winning, but terrible if you want to have an interesting discussion. Negativity is highly correlated with nitpicking in this respect :-)

I remember the first year here i had a long discussion with MattMaroon about a linked story where a consultant had saved a company 100 million dollars by changing a few bits and pieces around in the check-out process. He was concinced the company was Amazon, I was convinced it wasn't. The discussion dragged on, and we each tried to throw statistics, numbers and good guesses on the table, until at the end Matt found a link directly confirming that it was indeed amazon. He was right, and we were both happy because now we knew. I don't see many of those discussions anymore. Unfortunately.
Very funny. When you hear the words “deep cut,” you envision starting at the top and cutting deep into the heart. But no, in business, “deep cuts” means starting sideways at the bottom and cutting straight across, leaving the top unmarked.

A low-end dedicated DAC is likely to be a substantial upgrade over a built-in soundcard (I'm assuming we're talking PC sound here). A PC case is a pretty noisy place, electrically - I know one one work PC I had once you could actually here the mouse move, if you had heaphones on and cranked the volume with nothing playing - horizontal and vertical movement had different frequencies.

The move from a low end ($150-300) DAC to one much more expensive will be considerably less drastic, and likely won't matter until you've dropped at least $5k in to the rest of your system.

That said, you may already own a DAC without realising it...as long as you're taking the singal out _digitally_ (e.g. SP-DIF or digital coax) to an external receiver, you're already in a pretty decent place.

One of the best Italian artists of all time, Giorgio Gaber, said once that "Democracy is Participation", or "taking part". Check the number of active voters in the US at most levels: it's depressingly low. Low participation means less democracy, it's as simple as that.

Most people thought it would have been impossible for a black man to be President of the United States of America, but for once "the people" thought differently, you got the highest turnout ever for a presidential race, and lo and behold, change happened (at least for that particular thing).

Try to imagine how things would change if you could add another 10 or 20% to that 63% who elected a black President. Now repeat that at any level: Congress, State, City, even school board. All of a sudden you have a decisive element that can change majorities and express real power.

The problem, of course, is that "taking part takes time". Politics is a very slow game, and most people have a life outside of politics, so they drop out (me included). Even voting every few years is a problem, if you can't afford to take a day off; most European countries recognize that, and vote over the weekend. I find the US stance on this incredibly maddening, and clearly a legacy from the dark times of slavery and "gentlemen" landowners who didn't have to work for a living.

The problem, going forward, is how to give people the opportunity to take part more and more, while minimizing the time they have to spend in order to do so. One of them is having a good set of impartial media who can summarize honest arguments in a faithful way, providing different levels of analysis that don't contradict themselves. Another one might be some sort of collaborative service where people can contribute to the work of their representatives. Another might be a way of making representatives more accountable and in tune to the wishes of their electorate. And so on and so on... but nothing of this can happen unless we take part and move our ass, so to speak.

It's not like there's some kind of secret deal or something that limits that number to $12 / phone, it's just that it appears that in average that's how much iPhone users are willing to spend on apps currently. Apple and AT&T have a much larger marketing power than indie app developers. If Facebook suddenly started to charge $0.99 for their app, I bet that number would bump up to $12.70 fairly quickly.

Google, Facebook, Apple - all here in the bay area, all massive scale. Are yahooligans not flocking to these giants?
You always record stuff at 24-bit/192 kHz for many reasons usually involving minimizing analog artifacts and to give you a lot of information to work with. You use 32-bit float wavs to transport stuff around so you don't have to worry about normalizing levels and clipping. Lossless formats drastically improve the quality of transients by an enormous degree. But every single objection to this is either ignoring the points of the article, or talking about the benefits of recording at high fidelity, when this entire article is pointing out that once you have _finished a mix_, there is no reason to distribute things in 24-bit/192kHz. Most speakers can't even play about 20kHz anyway, which makes the entire point moot. I don't care if you have a bajillion kHz, the speakers can't play about 20 kHz, so your screwed.
Heh, it's funny to see this late-nineties debate get re-hashed here. Also kind of fun.

If it were true that there's no audible difference between 16 and 24 bit, companies like Alesis, Otari, ProTools, etc. wouldn't have spent the last 15 years ditching 16 bit like an old pair of smelly sneakers. (better metaphors welcome).

Seriously, anyone who has sat down in a real listening environment for 5 minutes A/Bing 16 vs 20 bit, 16 vs 24, etc. hears the difference immediately. There's no question. This is why you can buy ADAT 16 bit 'blackfaces' for $100, down from their original $4,000.
As much respect as I have for Bob Ludwig's hard won mastering skills, he also strongly believes in $n,000/foot speaker cable, which is what he has installed at Gateway. So by all means give him well deserved props, but don't assume he's an expert on all aspects of audio theory or practice.
> a time (denoted by the transaction number that added it the database).

Do transaction numbers have total order or just partial order? Total order is serializing. (And no, using real time as the transaction number doesn't help because it's impossible to keep an interesting number of servers time-synched.) Partial order is "interesting".
I have been the first to trigger two CPU bugs and came across a third a few days after it was discovered, before it was published. Once errata are published, software workarounds are usually put in place quickly, and tripping over them is rare.

Compiler bugs are another story entirely. I have found dozens of them (confirmed), and I can find more whenever I feel like it.
The Internet of the Present
Many years of building audio equipment (in particular analog synthesizers), and equally many years of being meticulously anal with getting the best components for my circuits, reading specifications of down to every single op-amp I've ever employed, is why I think so.

I am not saying that there aren't any DACs on the planet that can't handle five millionths of a volt, but I am saying that five millionths of a volt isn't surviving through the particular DACs and the rest of the electronics used in your PC/living room hi-fi audio equipment.
Is Craigslist the best place to find a writing gig? It's a good suggestion :)
Heimweh and MMORPGs
I agree the damn room matters so much more. Also the distortion of most speakers is already the bottle neck in most people's systems.
Agree one-hundred percent about the room (although the prescription isn't always as simple as "get a thicker rug" etc).

The other issue regarding high-frequency sound reproduction is that in most cases, the loudspeaker won't be outputting much beyond 22-25 kHz (assuming very good quality loudspeakers, cheap consumer grade units might struggle to hit a -6 dB point at 18 kHz) and even for the speakers that have usable output at that range, the directivity at those frequencies will be so narrow that your head will have to be locked in the perfect "sweet spot" to hear anything.
I've seen people's pictures - they're receiving them already.
This article is one of the most lucid and accurate that I have read on this topic.

However, one thing that's missing here (and in nearly all other similar pieces) is a full discussion of the prerequisites of the sampling theorem. For example, the signal must be bandwidth-limited (and no finite-time signal can be).

But this is a minor concern, as there are many elements in the analog domain of the recording and playback chains that serve as low-pass filters - starting with the mics. So bandwidth-limiting is effectively achieved.

For a similar reason, the discussion of the "harmful" effect of high-frequencies to playback electronics and loudspeakers to be a bit overdone IMO. Peruse the excellent lab results of modern audio gear on Stereophile's web site. You'll find that bandwidths exceeding 30kHz are rare.

One last thing. When doing subjective "testing," keep in mind that what some folks are hearing may be limitations of their gear. For example, most DACs derive their clocks for higher sampling rates (88/96/176/192) by clock-multiplier circuits. IOW, 44kHz and 48kHz are the only ones clocked directly by a crystal. These multiplier circuits are often noisy, contributing to jitter. The audible effect of this jitter is hard to predict.

Bob

PS As an avid audiophile, I find the clash of subjectivists and objectivists on this normally-buttoned-down forum to be a bit of a trip.
I have to say that was probably the most comprehensive dealings with the issue of sample-rates I've ever come across. I'm not going to make the mistake others have of claiming falsehoods (all of which i've read so far have been debunked to my satisfaction by the HN users-- i'm impressed, guys).

As pointed out, mastering has vastly greater effect on the audio quality (and is often pretty poor[1]), and is the reason vinyl records often can sound better than their digital counterpart, despite being an inferior technology[2]. The DAC used also has a massive effect on the sound once you get into decent quality equipment.

Like the author, i'd also love to see some expansion of mixed-for-surround music.

[1] a lot because of loudness wars, as pointed out in the post, but also just due to a lack of time/care/love(/demand?).

[2] http://www.hydrogenaudio.org/forums/index.php?showtopic=6175... This thread explores the bit-depth of vinyl records, beginning with a claim of a maximum 11-bit resolution-- limited by the width of a PVC molecule the record is made from.
There's likely two different scenarios to consider.

The one we don't want to happen is: "I don't need a lawyer, I used that Docracy thing. I'm set."

The one that is an improvement is: "Well, I've got about $250 left in the bank, its that Docracy thing or the back of this napkin..."
If this were real, the way to start would be for the whole research set was released free into the public domain, putative patents included, so that the originator could not in any conceivable way make money off it.

How to Test Your Startup Idea
Great idea. Here's what I've observed:

1) Way over-estimated the "time to bounce" for an event. It happened to be just over an hour from occurring and when I changed the start time to "manually" account for rough travel time, a more reasonable Bounce time was suggested.

2) Throws "unrecognizable event location" for a typical address (which Google Calendar takes no issue with): Location Name, Street Address, City, ST ZIP

(Wanted to see if back-to-back events made recommendation based on being at the preceding event location, but... see previous error)
