I have some good news for you: For your goals, likely you do not have to wait for P = NP, even if it is true.

Or, for your goals, you do not need the extreme guarantees of P = NP, that is, guaranteed polynomial solutions for ALL your problems in NP, even the worst case that can exist.

Instead, likely you can make nearly all the progress you have in mind with some techniques that just happen to work well for your class of problems. This is what the history shows. That is, people have been doing well solving NP-complete problems well enough for decades without worrying about P versus NP. So, learn some of what has been done, as I outlined and more, and then add to that material in ways important for your problems.

Just MUST realize that the question of P versus NP has been formulated in a way that makes it often shockingly far from getting valuable results in practice. How can this be? Heavily because the P versus NP question concentrates on the worst cases that can exist, and the average cases in practice can be much, MUCH easier.

For more, pay close attention to the Department of Combinatorics and Optimization at Waterloo and Nemhauser's department at Georgia Tech.

Generally it will be tough for me to believe that the field of DNA biology has much knowledge of that material if only because very few people do. Indeed, your desire for P = NP does indicate that your field lets the P versus NP question keep it from going after the field's holy grail, likely for no good reason. Each protein you can correctly fold, each valuable molecule you can create, can be a big step ahead, even without P = NP. Net, f'get about P versus NP.

Next, as I outlined, even if tomorrow someone shows an algorithm that shows P = NP, there is no guarantee that that algorithm will be 'fast'. Instead, something with integer linear programming, touched up with various techniques, might solve nearly all your problems plenty well and be much faster.

Indeed, as in the classic Klee and Minty paper, the simplex algorithm is not polynomial but in practice it totally knocks the socks off the polynomial interior point algorithms. To be more clear, classic simplex runs in 3m where m is the number of constraints and we get to ignore the number of columns. So, classic simplex runs, in practice, faster than a polynomial of degree 1 in the size of the input data. Still, it's 'exponential' in worst case. There are more details on why in a classic paper by K. Borgward.

The polynomial algorithms for linear programming are way too slow for practice.

So, I'm not just blowing smoke here: DO work on your problems but F'GET about P versus NP.

There are a lot of flaws in this analysis...

1. Yes Techcrunch's traffic is down according to Compete but so is the traffic from other sites that cover the same space. In the last 6 months Venturebeat for example is down 73%. ReadWriteWeb is down 38%. Even smaller sites are down. CenterNetworks covers relatively the same space and they're down 38%. By comparison Techcrunch is only down 29%.

2. The author states Michael Arrington making increasingly inflammatory posts as a reason why techcrunch will fail. But in my experience such posts tend to draw traffic. More to the point Arrington has been at this for a while, he uses analytics and he's not stupid. If the inflammatory posts weren't getting results he wouldn't continue to post them.

3. The author uses Wavii as an example of how TechCrunch is no longer a "kingmaker" because they've pushed that startup and it hasn't gotten major funding. But said product hasn't even launched yet so it's really too early to receive more funding (they already got $2m in seed funding and that was only 9 months ago). So the example doesn't really hold.

4. I actually kind of agree with this point in that I don't really enjoy Paul Carr, Sarah Lacy or Steve Gillmor. But again the site has analytics so I assume they'd be gone if everyone agreed with me. So clearly they're drawing a crowd regardless of how I feel. The author needs to realize the same is true of his opinion.

5. The last point boils down to "the author doesn't like Arrington so he'll fail". Well...a lot of people haven't liked Michael Arrington in the past and he's succeeded in spite of it.

I'm not saying Techcrunch doesn't have its problems but they're far from "over"
Does orthogonal mean opposite or unrelated (not bound, free from connection) when non mathematicians use this word?
How about ignoring the tiresome commentators, and the tiresome commentators complaining about other tiresome commentators.
I hate how people cite Compete.com traffic graphs as "fact". Fact #1 is not a fact at all.

Reference point: http://siteanalytics.compete.com/macrumors.com/ (estimated traffic, graph goes down)
vs
http://www.quantcast.com/macrumors.com (measured traffic, graph goes up)

I also like how he cites Compete's numbers for TechCrunch (1 million uniques), but doesn't use Compete's numbers for his own site PostPost. Compete says PostPost gets 18k uniques/month yet he cites 100K uniques. Why not compare apples to apples?
Actually considering he was asked WHY he didn't choose them it was the perfect place for it. The fact that he bolded that line only served to highlight his real and only true objection --- the development environment. Everything else he addressed was secondary and he would have probably taken the job even with all those other points. After the interview it really doesn't matter much what the interviewing process was like, but the development environment is something that will be with him everyday.

His whole email could have been summed up as "you're on Windows, I don't do Windows". That's not condescending, that's his preference and HIS reason for not taking the job.
Except bribes undermine social fairness significantly. Notice that as the clerk presumably knows how much money he should give you for your tax returns there is a strong incentive for him to ask for a bribe that covers a significant share of your tax returns, effectively making the entire tax return process useless for the citizen.

Also, if you think of a slightly different scenario, imagine the office is only allowed to issue X tax returns a month (maybe the money comes in packets), and the bribe is required to cut the line. Now it's really unfair and wrong, and a lot more so for the briber than for the bribee.

You should have in mind that it's not actually that hard to bribe people indirectly. Any place with a bribing culture tends to have people you can hire to unofficially bribe some government employee to do something for you. In Brazil these are called "despachantes" (dispatchers), and even though in the last decade or so they have been getting progressively more useless as the country moves away from a bribing culture, you should keep in mind that a lot of despachantes are legally incorporated and even pay taxes. One can't be blamed for hiring that sort of person.
AMZN and GOOG have proven that pageload speed does in fact
directly relate to profitability.

Let's not forget that's the client side speed not a server side. The difference is important: the time to generate html on the server may be just 10-20 percents of total load time.

On the other side, client-side optimization does help your servers: imagine if you cut from 60HTTP requests to just 6—and did that with proper caching policy, so your servers won't be hammered on subsequent page loads just to answer "304 Not Modified".

Ever since I got interested in client-side optimization (a bit over two years now) I am amazed how neglected this aspect is. I may be biased, of course.

Concurred. I found the Chancellor's message re: "academic freedom vs. right to know" objectionable based on the premise that all should be equal under the law. (Personal information such as interactions with students or casual interaction with colleagues are of course rightfully exempt)

Specifically exempting documents on the basis of ensuring that "the development of ideas can be undertaken without fear of premature exposure or reprisal for unpopular positions."

To give you a concrete example of why it is necessary to prematurely expose unpopular ideas, in Australia there was a proposal within some circles to log all internet traffic. What do you mean "log all internet traffic"? Do you mean like HTTP URLs or IP addresses or what? Is it only against bad people or based on keywords or what?
Well nobody really knew. What was known is that bureaucrats had been holding meetings with ISPs to discuss something about data retention.

So, there's a sort of secret idea being investigated using public money - the public has a right to know what it is and how far along is it, especially if industry are allowed to know, right?

> The Attorney-General's Department legal officer, FoI and Privacy Section, Claudia Hernandez, wrote in her decision in releasing the highly-censored document that the release of some sections of it "may lead to premature unnecessary debate and could potentially prejudice and impede government decision making".

Doesn't it seem obvious that people will try to "impede decision making" (via their elected representatives) of an unpopular decision? Isn't it a waste of public funds to explore an idea thoroughly without first consulting with the most populous stakeholder?

Bah. The owners of the USA are way too competent to let themselves be taxed. Manufacture of consent is their top expertise.

A lot of development work is aimed at streamlining people's work processes. These are not make-or-break issues, but the hours of wasted time add up when your UI forces you to navigate through multiple screens needlessly. In that sense there is always a business justification: you are increasing the efficiency of your employees on the job.

What I said in (2) is not nonsense but actually important in the 'sociology' of that field of research: There are people in the field very much hoping that P versus NP will not be resolved so that they can have long lasting jobs, and you would be naive about people and their tactics to say this is "nonsense".

You seem to be forgetting my introduction that I agree that the question of P versus NP is important. The question is good research, and your point is one reason it is.

Note: Although in computing your use of 'orthogonal' is common, a better word choice would be 'independent' or just 'unrelated'.

For you I will try to be still more clear: When I started working on airline scheduling, I talked to a famous mathematician and explained my airline fleet scheduling problem. Right away he said: "NP-complete" and then dismissed my work as hopeless. He was wrong, badly wrong. Airline fleet scheduling can work quite well in practice, thank you. His blurting out "NP-complete" was just a way to dismiss practical problem solving.

For some good public information on airline fleet scheduling, see the work of Ellis Johnson, then at IBM's Yorktown Heights lab, using IBM's Optimization Subroutine Library (OSL), for American Airlines. Ellis understands NP-complete just fine, but he also knows that it's possible in practice to do quite well on the NP-complete problems of real airlines.

Again, our goals in practice do not have to wait for P versus NP. Read again what I wrote about the cartoon.

Costly Malicious Data Breaches On the Rise
The author, like others who push this philosophy, ignores the gaping hole in his plan. Which is that countries are separate and competing in entities. So if a country like Great Britain has fewer super rich people than the United States it's in their best interest to use a lower tax rate to draw those super rich people across the sea.

Since there's so many countries in the world there will always be at least one that's willing to have a super low tax rate to draw the rich to them. Because getting less of rich people's money is better than getting none at all.
I described the reasons. E.g., hype.

Also, the paper was eager to assume that a polynomial algorithm that showed P = NP would be fast and that the world would then get big savings in airlines, manufacturing, etc., and that's nonsense. Generally we can get all but the last pennies of savings now.

Net, the paper is increasing the high confusion about the problem P versus NP.
Probably the specific isotopes detected. Iodine-131 in particular has a half-life of only eight days, so if you detect it you can be pretty sure it recently came out of a nuclear plant somewhere.
For non-US citizens/residents who are building startups focused on the US market, do you have any suggestions on where to incorporate (e.g. in the US, offshore, "home" country etc)? How much of the decision should be based on potential legal issues and how much on tax?

Well first if you are going to use Bill Gates as an example you should know a little bit more about Bill Gates. Bill Gates is a very liberal guy. He's on record as saying he doesn't plan to leave any of his money to his children and plans to devote it all to charity just as one example. His father, who's also the head of his foundation, is on record as saying he is in favor of and 99% tax rate. So Bill Gates really doesn't care.

But on the topic of just your ordinary super rich person I think you're right. One or two percentage points won't make a difference to them. It certainly won't motivate them to leave the country. But what this author seems to be suggesting is that taxing the super rich can solve all of society's ills. In order to do that you need to tax them far more than just a couple percentage points. And everyone will have their threshold. The super rich can afford to fly back and forth all they want so eventually they're just going to move their official residence elsewhere and fly back to the United States when they need to.

(To give just one example Arnold Schwarzenegger literally commuted by plane during his second term as governor of California. He would fly, via private plane, to Sacramento in the morning and then fly back to Los Angeles in the evening)
generally speaking, i'm no fan of interlace either, but my argument still stands that it could be used expressively -- in other words, to enhance the experience of the content for appropriate material. as an example, it might be a good choice if you were making a program and you wanted to exploit the impression that the viewer was watching a tv broadcast from a few decades ago.
