CTs (http://en.wikipedia.org/wiki/X-ray_computed_tomography) and PETs (http://en.wikipedia.org/wiki/Positron_Emission_Tomography) are pretty cool as well. CTs use essentially an X-ray beam that travels in a helical path around your body, and then use math to construct a 3D image, PET is the one where you drink an isotope, and they "catch" the positrons emitted from the radioactive material in your body.

Would also like to point out that culture driven entrepreneurship may be slightly of a different kind than we are acquainted with (startups/VCs/business plans etc.). These people may have for example started with being a taxi driver and grown to be the owner of travel company.
That is such a crock. Even if you attribute the worst possible motives to this mythical "Valley," pure greed, they'd be psyched to invest in you if they thought your future trajectory was going to look like Dropbox no matter how you got to wherever you were. The one thing venture investors are not is ideological.

Ah, so what I'm missing is that you think the boxes may be arranged in other than a straight line.

Your reference to topology confused me. I thought you were referring to the topology of the cyclic structure(s) induced by the permutation, not to the geometry of the physical arrangement of the boxes.

Now I understand, but I still think theproblem statement is clear.
That's just asking for trouble.

Now we're speaking past each other. Sorry, I was imprecise. My complaint is that you're describing one business strategy as if it was the defining attribute of a company, and it isn't. 37signals was a consultancy, then it was a product company. Tomorrow it could be a "pg-style" startup, if they decided to pick a product and shoot for the moon.
Suppose each accelerator funds the top n startups, where n is the amount of slots they have open. In that case, comparing average results would be unfair. Compared to an accelerator that funds n startups, an accelerator that funds a smaller number n' of startups would fund the top n' startups rather than the median n' startups.

If you take the top n' startups funded by YC, where n' is the number of startups funded by Techstars or Seedcamp, how do they compare then?

Lest this thread become an echo-chamber of cheerleading for new FCC regulations, I should point out:

- each such new rule on broadband providers brings closer the day the FCC adds content-censorship rules to internet communications, as the FCC already applies to broadcast TV, and as other nations -- even those we don't think of as especially prone to censorship, like Australia -- have started to apply to the internet

- this closes off potential business models for upstart bandwidth and content providers. Oh, incumbents will be sure to have their preferred models interpreted as being in compliance. Disney's ESPN360 will still be able to negotiate ISP-by-ISP video access [1]; Google will still be able to pay ISPs to install its edge caches so Google's traffic is the fastest on the internet [2]. But if an upstart wanted to offer "free" broadband subsidized by sponsoring sites -- for example, a service offering 6Mbps to paying sponsor websites, 128Kbps to everyone else -- that'd be unfair discrimination, until sufficient lobbying/donations occur to get a favorable FCC ruling.

The only good thing I see in the rules is Genachowski's second rule, "broadband providers must be transparent about their network management practices." Transparency can help consumer activism and competitive choice control abuses better than any agency rulemaking.

This is what struck me most about the academics (!) who were criticizing his work in the article.

"I find it useless to argue with people like Ogbu," says Urban League educational fellow Ronald Ross, himself a former school superintendent. "We know what the major problems in this school system are: racism, lack of funding, and unqualified teachers."

This guy's issue isn't with any particular bit of Ogbu's methodology or logic, just the places it takes him.

How this can fly in any academic field is shocking to me.

How do you mean "losing intelligence cred"? Do you mean that when CIA agents go to a spy conference, the Russians and Chinese look down at them?

The story is interesting history. I don't see any reason why having this information available at this point reveals anything useful to our the U.S.'s enemies. The U.S. made it perfectly clear it was on a mission to secure nuclear weapons and materials after the Soviet Union fell. The fact that it actually did secure some weapons and nuclear material simply shows they were at least partially effective. To me that increases credibility.
Ask HN: I offered free promo codes for my iphone app but....
Hi All

Yesterday I wanted to give away some promo codes to my new iPhone app but only one person wanted one.

Was it inappropriate to offer this on Hacker News? There were no catches or tricks. It was a genuine offer. I just thought it would be a good thing to do (for me and HN readers)

Any suggestions on what to do/ not to do would be much appreciated :)

Here's the original post:

-----------------------------------------

Ask HN: Anyone want a Free promo code for my iPhone app?

Would anyone like a promo code to test my company's iPhone app? I have ten to give away valid in the U.S. app store.

It would be really cool if you could write a review on the app store afterwards. Be honest.... but be nice :)

Go to http://www.joubee.com and fill out the form and I'll send you a code. Thanks so much guys.
What got me at first was reading the solution and thinking: "Oh, so they're allowed to label the boxes beforehand? Lame." I assumed by "label" the solutions meant "physically write on the box."

It took awhile to sink in that the prisoners could use their own memory, instead. Randomly line up, and have each prisoner memorize all prisoners' numbers in line. Then, agree on the numbering structure of the boxes in the room (eg: left to right = 0 to 100).

This fails if the warden is allowed to shuffle the boxes before each prisoner selects (not likely). It also fails if the room were rotationally symmetric, and each prisoner was brought in from one of two entrances. This way he would be unable to identify the "left" end of the line of boxes. (Much more likely, were I warden).

I would guess (like in everything else) Intelligence agencies have a ranking order and people in the business know who is good , who is very good and who is terrible. I guess it could be considered "cred" of a kind.

Like programmers might say "Google used to be very cool 5 years ago but these days is just a cube farm", I can imagine people in the spy business saying "The Americans were really good, but after they got into Iraq and Afghanistan, they've been slipping" or something like that.

How people like us ever get to hear an opinion like that is a different question entirely.
It's was most probably in DICOM (http://en.wikipedia.org/wiki/Digital_Imaging_and_Communicati...) - pretty much a standard nowadays and you can find a lot of FOSS applications that can read it. Just watch out for the file sizes - those images are not compressed high-resolution 3d 16-or-more-bit grayscale, so you need massive amounts of ram/swap.

The format itself is cool though - it can support annotations, arrows and basically anything-you-want overlayed on certain parts of the image afterwards.

Ah but Goggle is a big boy with lots of money. It's much easier to pick on a smaller opponent.
I wonder if this, or a variation of this method, could work with a product that the customer was not used to it's price/value. Almost everyone expects the price of a cd to be in the $10-$25 range, but what about something that it's value is completely relative to the customer's attraction to it, and his knowledge/expertise on the subject, e.g. a painting or maybe a consumer electronic device?

(I suspect the need to create an emotional attachment plays a vital part in succeeding with this)
Ignoring your views on The Pirate Bay for a moment, you have to wonder what could lead to such many conflicts of interest. Is it really that common in Sweden for law professionals to be so tightly involved with the entertainment industry?

The main police investigator was working for Warner Brothers.

The first judge, Tomas Norström was a member of the Swedish Copyright Association. Three of the plantiffs lawyers are members of this same organisation. Norström is also on the board of the Swedish Association for the Protection of Industrial Property which means he has strong enough views/influences on copyright to actively participate in an anti-piracy organisation that interacts with the entertainment industry i.e. plantiffs. These connections were undisclosed.

One of the original three allocated lay judges to the first trial was a member of a composers' association actively involved in advocating further copyright protection. Fortunately he excused himself from the trial.

The board to review the alleged bias of Tomas Norström was originally meant to include judge Ulrika Ihrfelt who was also a member of the Swedish Copyright Association. It is claimed that all Swedish copyright practicing lawyers have membership to this association but because of the potential conflict she was removed from the bias investigation. She is now the judge in charge of the appeal. However, it would appear that as the membership was back in 2005, and passive membership in this organisation is at least common for copyright lawyers, bias is not an issue with judge Ulrika Ihrfelt.

One of the three allocated lay judges to the retrial is also an employee at Spotify, who are a paid peer-to-peer music service that includes the major music labels (plaintiffs) as shareholders.

On an unrelated note, one of the titles The Pirate Bay are being charged with distributing is World of Warcraft, which is absolutely useless without a purchased cd key and subscription.

People respond to incentives - that is the the fundamental idea on which economics is based. The poor aren't as helpless/stupid as much of the developed world makes them out to be. This was one of my frustrations while working in the developing world. While I now work largely in China at least in China they don't assume that in order to help the poor that education comes first - they have first provided the conditions that businesses can meet the needs and employ the poor (one of the reasons China's growth exceeds much of the developing world and especially those who rely on "aid").

We claim that providing financial services will provide empowerment (which it does), and then we try to force them to conform with our view half a world away with how they should spend and save their money by structuring financial products according to our needs as opposed to theirs. They don't need an education to save - that the service exists and incentives to save exist are enough as they will quite quickly educate themselves in that regard. No level of "education" will disabuse someone (anyone let alone a poor person in the developing world) of the notion that their government isn't corrupt or that they can "trust" an institution. Trust is earned. What you will have, like in any society, is first the incentive/need, then the early adopters and then word of mouth and that's how institutions earn trust.

Listen friend, this isn't what Ruby is good at.

Acquire a C program, a C-Assembler program if possible and drive it from Ruby with an API.

Yeah... sorry about that. I misunderstood what you were saying.

In that case, the only issue I have is the first transformation. Instead of "connection to capital" -> "connection to finance/consulting interviews", I would instead say "connection to capital" -> "connection to more lucrative jobs". Though perhaps my opinion is colored by the fact that the consulting and finance interviews were hugely cut in the last year, and so a lot of my classmates have gotten interviews/jobs in other sectors. And those jobs are still quite lucrative.
I think it's a great idea, and can't see anything wrong with offering like-minded thinkers a chance to test it out.

If I had more time I'd definitely give it a shot. Surely there's some folks who would gladly give it a chance!
1) It's radio energy, not the ionizing radiation that we associate mutations and cancer.

2) It's actually very low power. Most of the energy in an MRI machine goes toward maintaining a super-high magnetic field. The radio energy used is on the order of a few watts per kg body weight.

3) The danger isn't being irradiated. The danger is being cooked.

Obviously this topic will tend to be highly subjective as the tools (at least for me, ymmv) have not been different enough to matter.

I personally feel it's a matter of what you enjoy using more. Before Windows 7 I would have given OSX with the better user experience overall, but after using Windows 7 for the last 2-3 months, I am so impressed that I don't dread going back and forth between it and my mac at all. It's a fine operating system that is a pleasure to use.

That said, for development reasons, I tend to stick with OSX simply because of the unix shell (though with how easy it is to spin up a virtual machine with linux now days, this might also not matter as much anymore).

So really I don't see a clear advantage either way, I think it all depends on how much you enjoy using one vs the other, as your environment enjoyment will probably affect your productivity more than just the actual platform.

If that's the correct answer (which according to a TechCrunch commenter, with working showed, it is), it's not Google. There's a voicemail system saying something along the lines of "Congratulations on solving the second, harder puzzle. Unfortunately, we're not Google, but leave your name and number - you won't regret it."
I'm not even sure why qualifications are the benchmark for some of these visas. As it stands you need either a bachelor's degree or 10 years working experience to justify as qualified for most visas I've seen.
Video: Pool-Playing Robot Is Unbeatable
C64 had better graphics modes available. It had higher resolution and better color availability (same number of colors, but the C64 could use more of them in a smaller area). The C64 had quite powerful, for the time, dedicated chips for sound and video, including providing hardware sprites, which took a lot of load off of the processor (a very similar CPU was in both the Apple and C64), so the C64 could do more on screen at once.

Also, because of the popularity of the platform, developers knew it really well, and were able to utilize tricks to occasionally go above and beyond expectations (for example, it's possible to get a lot more than 16 colors out of the C64, particular in still images). These undocumented modes and techniques became pretty common knowledge through the several magazines that covered the platform, and through various demo/warez scene channels (like bulletin boards).
Spoken like someone who has never had a baby. :P The urge to do violent things at 4am after 2 weeks of almost no sleep is very real and hard to control under those circumstances. There's a reason these same techniques are used for torture. It's somewhat ironic, though, that every parent has experienced them to some extent and we consider it part of the "miracle of life." :)

I'm a designer and the two books I always recommend to non-designers and newbies are:

and

The other is the complementary case studies book "Design Evolution" (http://www.amazon.com/Design-Evolution-Handbook-Principles-C...)

Also Graphically Speaking is useful if you want to know how a particular style is constructed (artistic, corporate, vintage etc.)and you need to be able to effectively communicate with other designers or clients. (http://www.amazon.com/Graphically-Speaking-Achieving-Designe...)

>I can image having to check every week whether something I've written and copyrighted has appeared on their site, and I think it's unsupportable that they say "It's your problem to check - tell us and we'll take it down."

But that's the law. The DMCA states that service providers don't have to do filtering or checking before they're notified of a violation. Scribd (according to the article) is even making it impossible to re-upload a document taken down under the DMCA. So they're doing more than the law requires.

What would you have Scribd do? It's not like there's a database of every copyrighted document ever, so they can't blacklist documents.
>"intermeddling with goods belonging to someone else, or altering their condition, is a trespass to goods and will entitle the photographer to claim compensation without having to prove loss."
