Possible proof emerges that P != NP... bit rusty? We explain the basics
I am not entirely sure about myself here, but I think, I kind of like the way people handle this. Sure, there will be a lot of questions which are trivial to someone deep in the field and even more questions which are already answered in the paper, but these should be removed pretty fast. However, those questions which are not answered via "See page X" or "Look in that book, page X" will need explanation and will strengthen trust in this proof, should it be correct.

funny thing.. when I google about lulz, first result tells me "The term lulz was coined by Jameth, and is the only good reason to do anything, from trolling to rape."
Note, I have not read the paper in detail yet, I just want to explain certain statistical proof techniques which are quite counter-intuitive to me, and maybe help you :)

You can, for example, show the probabilities of certain properties of an algorithm and use these probabilities in order to show the possibility of something existing or the absence of something. Furthermore, you can for example use the expected value of a certain process to demonstrate that solutions with a certain value exist.

For example, if you are able to demonstrate that the expected value of a maximum cut is 5 for a family of graphs, then you can conclude that there are maximum cuts in this family of graphs which have the value of at least 5. There are some with less, and there are some with more, but cuts with weight more than 5 exist.

Or, for example, if you can demonstrate that the probability of a turing machine in a certain class accepting or rejecting after a polynomial time of steps is 0, then it is impossible that this class is identical to P. On the other hand, if it is possible to demonstrate that this probability is not 0 (and thus larger), then we demonstrated that the cut of this class and P is nonempty.
This is also how the first ever Lisp implementation was made.

Supposedly, McCarthy had never intended his definitions of EVAL and APPLY -- not in this "micro-manual", but in his original Lisp paper -- to be actually implemented. Some guy called S R Russell (I imagine him as a graduate student but have never checked) looked at the paper and thought "wait, we can type this code in, write a bit of supporting code, and get an actual Lisp implementation", and so history was made.

well its what a common household would pay for that kind of electricity. i think starting from 5k kwh per year the local power company will start offering "power user" quotes (even for normal households). hetzner is one of the biggest server providers in germany so i imagine that they have huge datacenters and thus huge power consumption. its not entirely impossible that they can get below 0,1 €/kwh if they guarantee to take several 100k kwh. additionaly they can cut deals to bring the price even lower if they take the same amount around the clock (electricity is a lot cheaper at night).

>Both claims are provably false if you have a quick look at the literature.

Which literature? You're doing a bit of a (probably unintentional) bait and switch here if you mean the article you submitted. The article talks about learning rates of rats. Rats don't have language. How does having language change the picture [1]? We can't answer that, and therefor we can't know how applicable information about rat learning rates is to humans.

[1] Language certainly makes us more intelligent but there's also been studies that suggest that language may also dampen certain inherent abilities. In other words, maybe some people are born with drastically more "powerful" brains but language removes their advantages effectively evening out the field.

There is way too much we don't know about all this stuff for anyone to have such firm opinions on the mater. Certainly such limiting ones of "well, you're just not smart enough to ever be able to do this".

is this the same Marc Andreessen that has invested in Digg, where Kevin Rose reported on a site without saying that he actually owns it?

Or maybe it's the same Marc Andreessen that sits on the board of Facebook which did a ton of unethical things to get off the ground?

The bottom line is that if you can think of a successful business...somewhere in it's early days they've done something that would be considered unethical in order to gain traction. The guys who played by the rules when they had nothing are no longer around.

Granted there are probably a few companies that actually survived...but chances are they got extremely lucky.

Why exactly?
Hm, I disagree with one point: Don't display ways to fix the problem only. Of course, if the voltage is low, then the power cable is the most probable source of issues, but what happens if it is not? In that case, I have to reconsider why I need to check the power cable. If I see "Voltage low, check the power cable", you serve both the tech-savy and the old grandma. I can check the power cable, see it is ok and go ahead to search for other possible power issues while the casual user is also fine.
That is a more precise statement :)
There's a tendency here to excuse any such request with, "there's no budget", and, "these are tough times", which frustrated me when I was in the same position as you. Unfortunately, my advice isn't that good: I wrote a nice letter explaining why I deserve a raise and ended it with a threat that if I don't get it, I'm gone. Then, all of a sudden, the money was there ;)
This is a really interesting topic, I think. I read a lot of papers on distributed systems, and while many of the systems are conceptually not terribly complicated, there's a huge leap from understanding the concept to making it work. A good example of this is "Paxos made live" - conceptually Paxos is relatively simple, but even a top engineering team at Google had trouble implementing it well.

In the comments the point was also made that academics are simply not rewarded for making their work accessible - the theoretical work is everything. I made my first contact with a friend (and now colleague) asking him when he planned to implement a feature in the open source library based on his research. He said he had very little incentive to implement it having proved it correct. Until this changes, I think this barrier is unnecessarily high.
It's never too late to start a new career. At 51, my father decided he had had enough of the EE world and went to law school full time (where more than a couple of his classmates were on career #2). He's been loving it ever since, and there's no shortage of work for someone with a diverse background. If your dad is serious, I'd encourage him to give it his all (after taking into account what he can support financially, of course).
In England there are some Scottish notes in circulation, which as far as I know are legal tender*, but many people still don't want anything to do with them.

A friend worked in a pub where they had always had a Scottish £5 note in the till to give as change. More often than not the customer would just put it straight in the tip jar.

Edit: I am wrong about the concept of legal tender, and smazero is right. Interesting. Check out the few paragraphs beginning: http://en.wikipedia.org/wiki/Banknotes_of_the_pound_sterling...
It's actually very simple. So simple, in fact, that I'm surprised when people don't realize how to do it. But I've noticed that many people with greater social awareness than me feel there should be more to the process. Apart from being polite during the conversation, there isn't.

Step 1: send out a few feelers, try to find out your market worth. Call this $X.

If $X <= $YOUR_PAY + 3% (margin of error), STOP. You are not above the median and you do not deserve a raise.
(Most people think they are above average. Almost 50% of them are wrong.)

Step 2: start interviewing. Ideally get an offer above your pay (but not necessarily as large as $X).

Step 3: have a private conversation with your boss. Tell him you'd like more money, and you feel you deserve at least $X.

If he gives you the raise, declare victory and decline your external offer (unless you like it better). If he refuses or gives you a raise that is insufficient, either a) point out your external offer or b) give 2 weeks notice and accept your external offer.
Ask "the man" if he has any plans to increase your salary, or if there is a company policy that dictates that kind of thing. This way he will know that you are interested in a raise, you will know from his answers if you have any hopes of getting one, and then you can decide whether to stay there or not.
As a Canadian in the US, I miss my Loonie (1$ CAD Coin). I now open my wallet and say, "oh I`m good for cash, no need to stop at the bank" only to realize when I go pay for something that I have 10 x $1 bills. The ability to determine value of a bill based on colour, in Canada, is useful too.
Suggestion: you could put up a subtle fading slideshow of your styles (as soon as you have more than 4, I guess).

Flamebait isn't a great marketing plan. When someone says adgrok now I think, "hm that's the guy who wrote the rant that New York's tech scene sucks", not "that's the company who built a great product that will be super useful to me and maybe even help me make money". Sure, my perception can be changed - Antonio seems like a decent guy, but why start with a negative perception of the company based on a largely personal rant?

Maybe antonio can give us some signup stats to go with the wave of traffic? I'd certainly be curious about the effect it had, even if it was very general (up 4000%, etc.)

Ask HN: What tools are you using to manage your servers
Well, the 'S' of the SNMP stands for simple, yet, I wonder what is out there that can be described as "SNMP Made Easy".
I am looking for a suite of software which not standing in my way, easy to work with (install, configure), and basically requires no maintenance once installed.

I am about to deploy my software on around around 180 remote Linux servers and wants to monitor the servers and configure my daemons all from a centralized point.

Open Source is mandatory.

Since most of YC startups are basically SAAS shaped companies I guess there is enough knowledge amongst us that can be shared and useful for others.

And last thing, I strongly believe providing such suite, end to end solutions, can be a great business for a startup (but that is another story...)

Yes, i totally agree with all of that. They had a huge 'first mover' advantage. Just that there's no tech-wizardry involved in there closed protocol.
The US seems to have the worst currency setup of anywhere I've been. You have to put in a lot of effort to not end up with a wallet thick with one dollar bills and pockets full of pennies. The UK seems pretty bad as well since the the coin size doesn't seem to have much correlation to how much it's going to be worth.

The EU is better, but I find Switzerland the best so far. No bill smaller than 10, all notes are different sizes so you never accidentally pay with a 100 instead of a 10. A nice big 5cf coin (it's cool to be able to buy a new DVD with 3 coins or less) and no pennies. There is a .05 coin but it's rare, most prices are to the nearest 0.1. Every time I go back home I remember how painful the US system is by comparison.

I think 'legal tender' doesn't mean what people think it means; I heard some lawyer talking about this on the radio the other day: I don't remember exactly, but the gist was that the term legal tender is just to do with money that can't be refused as payment for a debt imposed by the courts.

For example in the UK no coins are 'legal tender' as they can be refused as payment for a debt, but still all shops will accept them as they have a fixed value relative to legal tender.

Alternatively my watch is not legal tender, but if I offered it to a shop keeper in exchange for a newspaper, there is nothing stopping the shop keeper from accepting it.
I've done this more times than I can count. It all comes down to accurately valuing your contribution and evaluating your position in the company.

If the work is steady and you are making a solid contribution, then there is usually much to be gained by bargaining for a pay increase. If work (ie: not necessarily "profits") is slow it is harder to claim you are due a raise if the organization is not operating near capacity.

I usually try to get a feel for other salaries in the company first (note: it is helpful to make friends with the HR people, even if you don't particularly like them, they can be a useful source of info). If the company has a general principle of paying way below average salaries, it's going to be harder to negotiate. But, if other people are making decent bank, your request is likely to be evaluated in proportion to other team members, and perhaps seen as more reasonable/rational.

But what it really comes down to is scheduling some time with your manager and laying out the details. There are a million variables, but you probably want to highlight your lack of salary growth while you've been there, your increasing contributions, fair market value for your position and so on. If your boss is weak, he'll probably tell you he needs to get approval and may reference some semi far-off non specific date/event ("the next staff meeting", or "after HR is done with the new benefits policy") if he won't commit to a specific time, tell him you'll check back "next Thursday" or some specific time.

In the end, few people have ever gotten fired simply for trying to better their salary and move up the ladder. Don't be intimidated by the process or make it into anything larger than what it is: a simple conversation.

Does this surprise anybody here? I don't understand the mainstream ignorance about the content provided online. There is a massive divide between internet lurkers and the minority that create content. Most people never reach that level.

And surprise, surprise. Most people that use the internet use it merely to entertain themselves and supersede other one-to-one devices such as the phone at communicating with people.
Can somebody explain to me why articles on complexity are careless with the term "Traveling Salesman Problem" (TSP)?

To me, TSP means "find the shortest route visiting these cities once". That is not a problem that's in NP, since there's no way to verify the solution (shortest route) in polynomial time. Am I right?

What people typically mean is the decision version of TSP: "Find a route visiting all these cities that in less than X total distance cost". That's in NP, of course, since I can quickly check (a) the route connectedness (b) whether the route visits all cities once (c) the total cost of the route is below X.

Do I have my terminology wrong, or are people writing about a very formal territory so unusually careless with terminilogy?
touche, for the record this is tip #1 for the year. More importantly, my money is where my mouth is. I have been long $ARNA calls for several months.
This is absolutely correct. Most people tend to fear step one much more then they should. I recently changed jobs and their offer was exactly what I was making at my full time job and my side jobs. I asked for a 5-10% bump, got it and now I have a new job (and I'm pretty happy about it). What surprised me the most was that I wasn't worth some arbitrary number to them, or a potential value that I wanted to be worth. I was worth exactly what I was able to get other people to pay for me, and a little more because they needed me too.
I asked to meet with my boss, we set up a meeting. I walked in and asked if my salary was up for negotiation. We had a short discussion where basically he wanted to know if I was unhappy or had already started looking for a job. I was quite pleased with my job and hadn't started to look (and probably wouldn't have if I didn't get myself a raise, but don't tell my old boss that). He then asked me what I think my salary should be. I told him. He said that probably wasn't going to happen (It was like an 18% raise) but he'd talk with his partners (He was the CTO/founder). A few days later they came back with like 15%. I told them I appreciate the effort but the number I gave wasn't really a starting point for negotiation and I still think I deserve what I asked for. I told him I wouldn't turn it down, but those are my feelings. A few days later the CEO met with me and basically did the same thing to make sure I wasn't unhappy about anything. He then gave me what I asked for and everything was good.

I wouldn't start sending out resumes and interviewing, seems like a lot of hassle when you haven't even talked to them yet.
