The multitouch screen interface. A mobile browser that works. Visual voicemail. Text messages threaded in a conversation view like a chat client.

And that was just version 1.0 in 2007, which is still better than most Nokia phones today. Then they launched the App Store and the iPad.

I'm sure someone had a touch screen phone, somewhere, before the iPhone. But no one nailed all those little features of user experience. I'm sure the software/hardware for a consistent multitouch screen capable of being manufactured at scale was alone a very big deal.

i have no clue who adam cohen is, but he clearly didn't even read the FAQ, let alone the fine manual, on bitcoin.

and to top it off, his 'analysis' starts with a diatribe BEFORE he make any point.

He may have a point on item 2 and 3. but reading point 1 was just whoooooosh.

It's not really a contradiction if you think in terms of equilibrium and system dynamics rather than an over-simplified quote from USA Today.
Yes, some quick googling appears to show that they've been pushing similar scams since 2007 or so:

http://www.google.com/search?sourceid=chrome&ie=UTF-8...

They claimed to have a 16-qubit machine then, whereas a recent (May 2) New Yorker article revealed that Oxford's research lab quantum computer is only an 8-qubit machine, and that's in 2011. Yale has built one and it's only 2-qubit.
I grew up in Clayton, MO, and this is the former St. Louis Bread Co (now Panera) that I have been going to since the early 90s. I live in SF, but I go back there several times a year, and I have been to this store since it went to its current pay-what-you want model.

A few observations:
1. As the article indicates, the system is really confusing. People who haven't been there before have no idea what's going on. They ring up the total amount as if you were purchasing the food normally, and then it's up to you what to do. If you decide to pay, they can make you change. For example (IIRC), your sandwich is $7.50, you put $10 into a little donation box, and they give you change of $2.50. The first few times I went I wasn't sure what to do.

2. It's in a fairly nice area of St. Louis (right across from the county courts+jail as well as several small high-rise office towers). There isn't a huge homeless problem like you would have in downtown SF, where it would effectively be a soup kitchen.

3. The neighboring businesses hated it--they viewed it as a big chain driving them out of business by undercutting prices on lunch. One business on the same block posted a big sign in its front window protesting the move. I don't know if any competitors have actually closed as a result, but they certainly didn't like the idea.

4. This location of BreadCo/Panera has always had low-price day-old bread and pastries available, iirc. They are now pay-what-you-want, which means mostly free. They keep bags of them by the door, and I have seen folks (most of whom look like they need it) take them.

Having been there a few times and as a fan of STL Bread Co, it's hard for me to believe that this would work on a large scale.
or maybe neither. Dwave has been around for a while and while the question is still out on how useful their devices actually are they have been publicly demonstrated and available for at least a few years. Google has even used their machines though I think just for research purposes.

and on point two, he also compares bitcoin to a currency that has a government printing money.

the fact that you want a currency to look like a number of twitters graph he show is because you are assuming inflaction by government action. Where people gamble with the need of said government to print money!

if you remove government action, of course people will hold to money --if they do not have the need to spend. that's the whole point of it!

I hold down to my money in the hopes that i will have means when i need it. economists juggle money to trick me out of my wealth while i sleep!

Very interesting: you make a good point about hardware. If I were to take my interpretation of software being unpatentable to the absolute extreme, I would say that the microcode in modern CISCy CPUs would also be unpatentable. This could lead to an interpretation where CPUs are also not patentable.

I had an inkling feeling that the software/mathematics argument is not compelling (not because software isn't mathematics, but because the practicality of invention and patent render it different in practice), but couldn't articulate it.

I still think that software patents have turned out to be dangerously unproductive in practice and so would rather see them abolished entirely than in their current form, but I think I more fully understand my position now. Thanks, Colin, for participating in this little Socratic dialog.

Scott Aaronson is an MIT prof and a leading researcher in quantum computing. Here is his take on a recent paper DWave published in Nature:

(And the Nature paper: http://www.nature.com/nature/journal/v473/n7346/full/nature1...)
Maybe. But if you try to check, it may affect the scam result... i mean test results.
Then perhaps the issue isn't that software isn't math, but that the statement "math can't be patented" was simply one made in ignorance and not reflective of the underlying spirit of the law?
It's cheap and easy to use a distributed network of DNS servers with locations around the world. There's much less network latency when the edge locations are closer to the end user. There are dozens of good DNS providers out there. We currently use DNS Made Easy, and we're thinking about using Amazon Route 53 as well.

If you have multiple web servers servers in different locations, you might be thinking of "Geo-DNS" -- this actually directs the end user to the nearest web server. There are pros and cons to this approach, namely that the end user may be using an intermediary DNS server that's not actually very close to the user. For example, you might end up sending all Comcast users to your east coast USA server, no matter where in the USA they actually are. I'm not familiar with providers who offer this service, but here's a Server Fault thread on the matter: http://serverfault.com/questions/30567/geo-dns-providers
The big tests for Mongo are how well it behaves under heavy load, how easy it is to shard/replicate data at large scale (e.g. what Zawodny was talking about in his presentation about Craigslist having 100 MySQL boxes), and to what degree data is recoverable when inevitable failures happen (there are some big questions here with Mongo since it appears it trades off ACID compliance for speed).

It's great to see bigger users using Mongo because that's where these tests really take place. For example, it seems Cassandra got tested this way at Facebook/Reddit/Digg etc. and didn't cut it.
A fair point. I concede that may be true.
Sweet! Installing it now (disclaimer: I'm Pete's friend, sort of, kind of mad he's leaving Camb for YC but still.)
We are entering an era where the consequences of our interaction with machines won't exist in a one to one relationship but rather in a one to many and many to one.

Attempts to manipulate or browse large amounts of data will require much more from the machines than from the humans controlling it.

Any routine initiated by the user will be have to be followed by a very large set of sub-routines in order to provide feedback. It might even have to anticipate what kind of feedback the user want.

Visualization is going to be the feedback but I don't believe the interface is going to be the screen.

I think you're reducing a hugely multivariate system to a univariate one.
D-Wave has been operating under heavy-duty NDA's for a long time. I know of at least two published authors in quantum physics who have signed an NDA and been given the grand tour. I know one well enough to have asked him what he thought without divulging anything he couldn't tell me. He said what D-Wave had when he was there was not a general purpose quantum computer, but rather, a sort of hard-coded specific purpose device not unlike an electronic circuit built to implement a specific algorithm rather than function as a general purpose programmable device.

Regardless, what D-Wave has is real enough that they are not being laughed at in the circles that matter. I would also say that they aren't doing anything that makes academics who are working on QC devices despair of doing anything useful themselves. I think it's rather unlikely that this device is going to be busting open RSA keys anytime soon.

In short, this is probably not fake or a scam. It's just not quite what the original poster was hoping it was.
It's not fake, but it's not the quantum computer you would expect.

http://spectrum.ieee.org/computing/hardware/loser-dwave-does...

"D-Wave's system uses a chip with little loops of niobium metal containing Josephson junctions—two superconductors separated by an insulator. When the chip is cooled to very low temperatures, tiny electrical currents flowing around the loops exhibit quantum properties, and you can use the direction to represent the states of a qubit: Counterclockwise represents 0, clockwise represents 1, and current flowing both ways represents a superposition of 0 and 1.

D-Wave's superconducting qubits are not new, and other groups use similar devices. But whereas most groups are trying to build the quantum logic gates from which all computing operations can be derived—an approach known as the gate model—D-Wave has adopted a different approach, called adiabatic quantum computation. Here's the gist: You initialize a collection of qubits to their lowest energy state. You then ever so gently (or adiabatically) turn on interactions between the qubits, thus encoding a quantum algorithm. In the end, the qubits drift to a new lowest-energy state. You then read out the qubits to get the results."

Even if autoload is slower, it's such a simple concept that even if you use it early on and need to take it out later, you wouldn't have to restructure anything. If you know performance is that big of a deal upfront, anything bug vanilla PHP might not be the best choice since the interpreter will probably become a bottleneck.
Ask HN: Is there demand for a completely new kind of SEO?
I'm an SEO. Yeah.. I know.... I too believe that SEO is a bullsht industry. The thing is: I despise SEO as it is currently applied to the online world, but I'm pretty good at it. So what to do: Start a company, disrupt the field (completely).

SEO is a mixture a marketing, biz dev, product development and technology (that's the cool part) - glued together by esoteric concepts (trust, link juice, ...) and a shtload of magic numbers (pagerank, ranking, mozrank,...). That's the awful part.

These esoteric, unquantifiable concepts together with magic, nontransparent, incoherent, foggy numbers lead to a state where everyone can advocate -in a seemingly logic way- the bad decisions he or she wants to make.

There are some companies out there which promised to solve these issues, but instead just delivered more and more magic numbers.

I want to get rid of it all. Instead of idiotic concepts i want the SEO world to work with hard, cold data and trends based on that data, instead of magic numbers we should create and work with traceable, comparable figures.

Oh, and I'm not targeting the goody two shoes companies out there which want to keyword optimize their title tags, but with companies which already mastered SEO but believe there must be a next level.

Oh yeah, and everything (every code) of course open source and every process automatable/scalable.

Is there demand for that? Or is SEO good enough for your company? Or is SEO already in such a bad condition, that it would be better to let the patient die?
I disagree with this article, and agree with the reviewer. The application is not useful at all, and what could have been an excellent UI, given a little more thought and power, is unfortunately just lipstick. Tracks and artists are grouped in 3D space by name alone, and their arrangement and spacing is meaningless. This makes the app a pretty, but useless skin of a simple playlist.

I think the design lends itself to music discovery, not playback. Hooked up to rdio or Spotify, this could be a fun way of exploring new music by proximity. Like this song? Here's 5 other similar artists nearby.

To me this speaks volumes about data visualisation. Done incorrectly, it's useless. Useful and simple will hopefully win over beautiful but impractical. You can't start with beautiful and add useful later.

Funny thing. Site supports it's claims by referencing 3 articles, whilst there are 10^2 articles claiming the opposite. Good old TV-shop marketing trick.
The obvious rhetorical question here is: Who seriously believes that there have been 500,000 inventions worthy of being patented in 2009?

The sheer volume makes it clear that the vast majority of patent applications are for trivial stuff. The system is broken, it's that simple.

My guess is that someone's already doing it. I've heard rumors of ex-Googlers that are using genetic algorithms to develop SEO models, which then automatically adjust whenever Google changes their ranking algorithm. There's a well-defined fitness function - your site's Google ranking in a basket of common queries - and a limited number of dimensions to generate mutations, so it seems well suited to that approach.

> I used to think the same way, but then I ran into a couple of cases where it was actually useful (it was in Python, where zip has the same behavior).

Then there's little reason not to explicitly truncate...

> Yes, but I guess that would be less efficient than the standard version of zip. You would at least have to check which list is longer, no?

A simple function like:

truncate :: List N a -> List M a -> (List (min N M) a,
List (min N M) a)

composed with zip, can be fused into the same original function as truncating zip -- there is no reason for it to be more expensive.

> Special cases often enable better optimizations, but I'm asking about the general case.

Note these same special cases will not yield any optimizations if you cannot encode that special case into the type.

> If the lengths are different this will give an error, although it's a runtime error so it's not as good as your version.

Actually, not having the pattern match for the empty/non-empty and non-empty/empty cases does not mean there is no runtime check.

You pay both with partiality (some inputs will fail at runtime) and speed (failed pattern matches still get checked at runtime). Dependant-typed zip gives you both of these back.
Pretty much all distributed databases trade off ACID for speed, it's a fundamental issue with database design.

If you've got 20 database servers, potentially on the other side of the planet from each other, if you were to be ACID compliant throughout the cluster, each write commit would be delayed up to 500ms or more.

If you're running a pair of servers in the same room, as is normally the case with a traditional "active-active" database cluster, a network delay of 1ms often isn't a significant impact.
What you're missing is that the state the company is located in doesn't matter. In general, if it's doing business in California, it can be sued in California court.

>While elegant, the convention of cons cells as lists is increasingly going to be a flaw, because using linear recursion to process a list often obscures parallelism

I disagree that it's a flaw. I think the problem here is this idea that we can only have one data type. For me, the main thing C++ got right was the STL. It didn't have one collection type, it had several. Each with its own set of trade offs. That's what we need in Lisp. You want instant insert but don't care as much about traversal? List. Fast random index-based access? Vector. And so on.
