We're considering building one of these but I used to work for a clustered storage vendor. The import thing to notice here is this is single client performance - aggregate performance is often considerably better. ie, you might be able to push 1GB/s with 10 clients, but only 100MB/s with one...
The Avengers is Going To Suck (official teaser trailer)
This is almost exactly the technology behind Shazam, which has a fairly extensive catalog. Shazam 'listens' to a song when you hit a button and captures microphone data from your phone. It then takes that recorded data and listens for 'key points', which it hashes and uses to compare against its catalog.

If you want to know more about how to implement it on your own, you could use this as a resource: http://www.redcode.nl/blog/2010/06/creating-shazam-in-java/

I assume the biggest drawback to be that Shazam uses a microphone, which is obviously subject to ambient noise. Shazam doesn't actually seem to have much of a problem with this, but I'm guessing a passive listener that sampled the audio output device instead of a noisy ambient microphone would work much more reliably.

No. If you rely on a lot of storage it pays to have really smart people building the hardware and software, and maintaining it, with service agreements in place.

If 100 TB was as easy as buying a bunch of discs and slapping NASlite or FreeNAS on them then everyone would be doing it.
How To Identify The Best Home Business Ideas
It's unfortunate the author leaps from Stallman's "computer as a jail" comment to this:

"It's at this point that I have to wonder whether Stallman or any of the other members of the free software movement have ever spent any appreciable amount of time in an actual jail or jail-like environment. "

This, despite linking to http://en.wikipedia.org/wiki/Jail_(computer_security) in the very first paragraph.

Sigh.
Having lived in the UK for a year, I can completely attest to the sentiment. The lack of seed funding appeared largely cultural to me: many of the angels I interacted with were risk-averse and old-fashioned, looking at rubber-stamps and degrees rather than actual merit. It seemed impossible to get funding as a young entrepreneur (under 25), given the heavy emphasis on traditional industry experience. From talking to other entrepreneurs, there was no tolerance for failure as there is in the Valley, and an utter focus on IRR and incremental businesses with short-term returns, rather than more risky bets with longer time-horizons.
Friend Scan Me Alpha released
It sounds like you think I'm belittling the iPad. I really don't know what's bad about being a really big iPhone. A different form factor of an excellent product can still be excellent. Apple made a great piece of hardware with some pretty crazy hardware wizardry, but non-techies don't care about that because they expect it from Apple.

I'm merely trying to describe what I've heard my non-techie friends praise about the iPad. They like that the user experience is almost wholly translated to the iPad. They like that they can get all the apps they have on their phone on their iPad. They like that it's bigger.

I've never heard a non-techie say "I really like this new dual-core processor," or "I really like the 4:3 aspect ratio as opposed to the 1.5:1 on the iPhone!" We (royal HN we) may love to obsess about all the little nuances that make the iPad different from the iPhone, but the fact of the matter is that most people just don't care.

I actually used this site several times before I got an Amazon Prime account, and I think it has real value.

My sister always got a kick out of the fact there were random pirate stickers (or some other random cheap item) in her birthday gift. Free shipping!

Cleaning up spam sites is great, but it feels like Google is editorializing on this. A fine line.
I think people either took it too literally, or are upset at the (unintended) comparison of Zuck and Jobs.
I had a similar weekend project[1] where anyone can write random posts with no setup required.

It's more bare bones (really bare bones, heh) and allows anonymous posts.

Hmm, even I abandoned posting there, though I'm not much of a poster in the first place.

Very low. I estimate the power consumption at the wall to be ~400W. That's $29/month at $0.10/kWh. Host this in a datacenter with a non-remarkable PUE of 1.5, and that's $43.5/month including cooling.

"You have reinvented Brainfuck but non-ironically" is classic.
The two necessary elements of a great blogger: patience and persistence.

Most people don't have either when it comes to blogging since there aren't really instant rewards for blogging and no pain if they don't blog.
It depends on how you use the list. If you use the list as a pointy-haired boss trying to micromanage somebody's work, that's one thing. But every one of those questions begins a conversation--like you mention with the reply "Why do you say it isn't?"

It's through those conversation that ensures that the best can ideas can come forth. This hinges on the relationship between the reviewer and the reviewee being solid, something that should be worked on long before the design review.
I wonder what this means for SEO? If they are actually fully rendering pages in javascript I guess that means you have to be a lot more careful about how pages are laid out.

It doesn't have the trinary options of "back support that jabs into your back like a knife" or "slightly less jabby but still painful" or "nothing." It doesn't have the steel bar at the front of the seat that cuts off leg circulation if you try to sit forward.

Seems more adjustable generally, and I feel that the arm rests are more fully adjustable in particular.

Tracking the Trackers: Where Everybody Knows Your Username
Free Airfare to Japan
I'm not referring to any specific amount of traffic. I'm referring to how users expect a website to work. If the user sees a link, especially a More or Login link then the user expects it to do just what it says. When those don't work I would call that a bug. I'm in agreement that this technique can be useful for rapid prototyping, but I also think this site is probably the most active and mass used prototype I've ever seen. ;)

My goal for a web site or web app is to have 0 expired links. Sometimes stuff you link to outside your site will go dead, and it must be fixed or removed or whatnot. But for your own internal stuff... I don't know... something doesn't feel right about an architecture that allows that systematically. How much time could you save if you didn't even have to worry about fixing any expired links? Any idea on what the ROI on your time would be?

Anyway, just thinking out loud. Thanks again for the site though. I do indeed enjoy it very much regardless.
Seeing as how this is on hacker news, are these "women" reviewing photos human or part of our migration to look good for our robot overlords (all hail!)? Because the latter would be so much more awesome.

Also I think this is a great idea since often people post photos that don't quite compliment them, even though there is a positive emotion associated with the photo, others see it differently. A nice way to get a human (or robot) review of stuff.

however:

a) seems to prey on people's emotional state when they are desperately hunting for a date. Basically I have no reassurance that these "women" are in any way good at rating profiles, or would be helpful. I may feel its better but it may not be.

b) why do women need be the only reviewers? Again pointing to (a). Men can do an equally good job granted that they have appropriate experience in the field, as they may know what works vs "what I would like, as a woman".

(b) seems to be the ux problems, users don't really know what they want, instead professionals know how to get to what the users want. %s/users/women %s/professionals/some\ men
I was always curious why he would wear such ill-fitting turtlenecks after he lost so much weight in his sickness. I guess his supply of turtlenecks had more of a personal story behind them and it wasn't as simple as ordering a size smaller from the local department store.
The expression "[...] is win" is decidedly not win.
http://www.filleritemfinder.com/ is the first hit for "filler item" on google right now.

A search for hacker news results in a page full of affiliate links, just as the example you gave above. Only difference is that they didn't re-write the URL.

filleritemfinder.com has no robots.txt that I was able to pull up.

So, filleritem.com, a google customer, was blocked, but filleritemfinder.com, doing the same thing, is the number one result.

Further, shouldn't this kind of advice be given to people who appeal being excluded from the index? Or should we all post to Hacker News when it happens to us so that you can come explain directly?

I think %50 of the problem is the arbitrary picking of sites to block (and it's not working, btw[1]) and %50 of it is that google seems uninterested in explaining or advising people when it happens to them.

[1] Been buying gear for a project lately, and so doing a lot of google searches in the form of product-model-number review or product-name review. Overwhelmed with spam sites, and mindless human generated spam sites like dpreview.com, etc.
Kind of fascinating where inspiration can be drawn from.
I couldn't agree more. Filling it out the first time we applied actually led us to the full developement of our business plan, right down to the design of the GUI and the financial metrics we would use. We now know exactly what is required of us to become profitable, how much we can stretch our margins, etc etc. Granted this is not necessary for YC but it let us know exactly where we stand and how hard we have to work before we can all afford to eat again.

The application process also taught our founders a little more about eachother. The things my cofounders put as their "most impressive acheivements" blew me away.
Why an exorbitant price tag? That will just fuel the black market that is in turn fueling the drug wars (read: with bullets and machetes and thousands of dead people) in Central America.

How about a reasonable price tag?

Or how about blanket legalization of cultivation, possession, and use? I can get a tube of spores for "magic mushrooms" for about $10 and grow my own indefinitely. But for some reason this activity (the growing and using part) is currently highly illegal.

I don't need a license to brew beer and drink it myself or give it away. Why should it be any different for plants and fungi?

Right now its all women, although I'm experimenting w/ Mechanical Turk to rate photos and other things. Hopefully I can lower costs by using our robot overlords.

I don't mean to prey on emotions, I just want to offer a service to improve your online dating experience.

I agree, men could be equally useful in judging profiles, I have to find out the comfort level guys have with other guys critiquing them. Personally I wouldn't care.

Not sure I understood your last point exactly, please elaborate..
I really love the way these guys go about things:

1. create something of value, but serious value
2. generate traction, but in a big way
3. go after capturing some of that value.

I like how they move to 3 only when 2 is fulfilled, like half the internet uses their product.

This seems to go against the current trend of first deciding to "do a startup", then figuring out what to do. Reminds me of something PG wrote in an essay about the craigslist way and staying "upwind" of profits.
Slow Money Movement Puts a Break on the Fast Food Nation
As an experiment, several years ago I released a few "fun" iPhone apps that leveraged OpenCV to do face detection and image replacement using the iPhone camera. I did dozens of successful tests before launch, and the apps have collectively been downloaded hundreds of thousands of times. I'd say overall effectiveness in the wild is pretty high, but it depends on the filter used. If anyone is interested I can send a link, but don't want to spam this audience with it.
You've touched on a few of the conceits in his writing style:

1) He writes as if you're at least somewhat familiar with the stories he's been telling all these years.

2) The stories are presented as parables, and the details may not all be 100% consistent from year to year.

The "parable" conceit could be a convenient dodge to avoid fully justifying or proving his points, but I've found the coherence and strong voice of the writing to be respectable enough so far.

If you're really curious about the names of the startups you can easily Google up his LinkedIn profile. Click through to the book covers on his site to find out his real name. Rands is a pen name that goes along with the familiar storytelling style of the blog.
Several of his arguments stem from his perl heritage. He gives a nod to moose's roles when complaining about Dart's weak OO (I actually agree with this one), advocates implicit conversions in stupid Perl-like ways, whines about + overloading in ways only a Perl user would, and relates Isolates to Perl's threads in ways that don't make sense based on my reading of the language spec (Perl's threads are way worse than what dart's seem to be!). Perl is directly visible in over half of his points! Some of his arguments are actually valid, but some obviously stem from his mind being corrupted from too much Perl use.
That's where the well-run meetings come in.

There might be some truth to Steve Jobs' view of LSD.

There have been studies that link psychedelics and aesthetics: http://yourlife.usatoday.com/health/story/2011-09-29/Magic-m...

I'd say LSD is like steroids for artists/designers/creative people or Adderall/Ritalin for students. Sure it won't make you creative overnight but it will reaaalllly help, and it's kind of dangerous. Most of the danger comes from illegality, of course :)

It is just a lot easier to come up with new ideas when your mind is open and sketchbook seems to be a direct extension of your brain, where you can just 'think' ideas with pencil.
Many articles have been written lately about how an outsider drop-out like Jobs would have never been given an opportunity to succeed in East Asia.

So it's interesting that here we have a story about how Steve Jobs tried to introduce a company uniform at Apple that emulated Sony. Especially odd given the "think different" slogan of the era.

In any case, I love the idea of a personal brand that doesn't change -- and also the practicality of never deciding what to wear.
To my mind, the bow-tie Steve and the turtleneck Steve are almost two different people. Long hair, sometimes a mustache, vs. short hair, the and maybe stubble. I've been following Apple and Steve for over 20 years, and there doesn't seem to be a transition between the two in my memory.

I don't think that it is as simple as that. There is some form of ecosystem on the web: there are the content creators and website providers, there are the searchers, and there are the search engine providers. Each of these has its own interests and guidelines.

Searchers have quality guidelines too, though they are not explicitly published by them on the web. If a search engine delivers low-quality results, the searchers move on to the next search engine. A search engine without searchers is hardly profitable.

Most of the quality guidelines of Google are just common sense, following them will in many cases increase the usability and findability of a site.

If this has happend to you many times, you are likely doing something wrong. I have never had one of my sites banned from Google.
Why limit yourself to an OS? Design your own instruction set, with a single-bit 'hw' instruction!

Hm... Didn't know that obviously jest comments are ill-favoured in HN. Hackering is a serious business apparently.
It's delusional in the same way that someone else telling me they had a religious experience is delusional.

I cannot prove [to myself!] after the fact that what I experienced under the drug was real. I obviously believed it at the moment I was under the effect of the drug, but afterwards I couldn't recall exactly why I believed that. In other words, there was no way to prove or explain it. So it's delusional -- an event is supposed to have happened but there is no proof of it.

There's simply no reason for me (now) to believe that what I experienced under the drug was real.

(As I said above, I still think LSD should be legal so we can scientifically look at reducing harms from people taking it)

From the blog post:

The source of the requests is our client-side JavaScript error tracking code, which installs a global JavaScript error handler and attempts to POST to our server when unhandled errors are detected on the client.

Sounds like Googlebot's executing more advanced Javascript, though it's pretty scary it's allowing POSTs to go through.
