Why is this upvoted? I don't get it. This adds nothing. No one panicked. No one suggested anyone was panicking. Having alternatives that you can switch on in the event one goes down is just good practice.
TradElect was launched at the same time that BetFair, a big internet betting exchange, announced its own FlyWheel platform. FlyWheel took 2 years to develop internally (apparently with two different dev teams initially competing against each other) at a cost of around £1m. It runs on Oracle/JBoss/Linux/x86 on £25k worth of kit, and does up to 1m TPS (compare with TradElect's £40m to achieve a target of 68k TPS, which apparently it never achieved).
Thanks. We actually do have PayPal along with their Payflow Pro. However, not all of our customers accounts can use PayPal hence the need for another provider.
I have experience with Auth.net and generally have been happy with them.

That being said, I also like VeriFone's offerings - very powerful and their rates are really good.

I've also used PayPal's Website Payments Pro and Payflow Pro - good experiences there as well.
Hey, Gtalk had a little bit of issue with decimal's. It was a case that just came to my mind when feedback started pouring in. Its been fixed now. I assume you also tried entering a decimal value.
Tell HN: Objecting to overly-aggressive moderation
I must have missed where the guidelines were updated to ban all relevant meta-discussion.

The title of the thread I started, "Ask HN: Objecting to the [dead]" was retitled "Michael Jackson story should not have been killed."

This is inaccurate. The point of the thread was to open discussion about a better way to handle killing/unkilling highly-rated story. I used a timely example that I felt characterized my point. If it needed to be killed, fine. But retitling the submission recharacterizes it in a way I did not intend.

PG is way more civil than this. So I have to imagine this is someone else. Please speak up.

Regarding: http://news.ycombinator.com/item?id=686200
Exactly. Facebook should be for friends and people you actually know. Twitter works best if you follow people with shared interests (professional or otherwise) that you may or may not actually know in person.
It's strange why my blatantly stupid post was upvoted.

I re-read all three problems after you replied and this is what I understood. Talking about Three Prisoners' problem since the article's wording doesn't include the very crucial ingredient for easier understanding: coin flip on warden's side.

For A, it doesn't really matter if B or C were executed. In fact, he knew that either B or C are going to be executed for sure. He knew that at least one person who is not him will be executed.

Warden just named the sure-to-be-executed-guy. Didn't change what he previously knew about his chances, since he still doesn't know for sure whether the-other-not-named-guy is going to be executed.

However, the distribution changed for C. Now A still knows that there 1/3 chance of him living but since we know for sure that the-guy-who-warden-named (B or C) will be killed the-guy-who-warden-didn't-name-and-who-isn't-A (C or B) will have 1 - 1/3 = 2/3 probability of living.
A lesson in business forecasting
Hey, where'd that comment go?
For the really mission-critical systems there's more COBOL, C++ and even VAX Basic (I'm not kidding) than there is Java, and there's a lot of mainframe and VMS too, and weird Unixes like Dynix. A lot of it is stuff that people outside the industry will never even see anymore.

One project I worked on in fixed income was C++ based, it could handle a few hundred trades per second on modest kit. When I left I think the J2EE rewrite was up to 6 trades per minute...
Auth is nothing more than a gateway, ie, hosted software. There are numerous gateway software available which you can run yourself and connect directly to your merchant acquirer.

Many might want to consider Chase Paymentech, the largest acquirer, whom you can directly connect with. Paypal runs their credit and partner transactions over the Paymentech network if that gives you any confidence.
Has anyone heard of paypal? Ever applied for their Identity Protection? Banking has been solved, security has been solved. Nobody cares; that's the real problem.
That figure is meaningless.

More interesting would be how many active users they have. I.e. how many users login and/or do anything per month.

Too bad they don't brag about that, I'm sure those stats would be impressive enough (albeit not in the "hundreds of thousads per day" ballpark).
It always warms my heart when the internet produces a relevant and interesting bit of original content. Sometimes I think this whole enterprise might actually have value.

I thought it was a given that MySpace is the epitome of ugliness. So my point was, maybe the "migration" has just the superficial reasons of ugliness and suckiness, not the huge society-psychobabble reasons.
Shot fired, one wounded at Virginia Apple Store
Forgive me, but doesn't it seem odd that the problem defines Prisoner A from one perspective, and Prisoner B from another?

Prisoner B could just as well be Prisoner A since A was defined by the narrator, and Prisoner B by the guard. I know we're descending into the theoretical stuff, probabilities and so on, but might there not even be enough information to go down any path at all given this dilemma?
Don't you all think its odd that all of a sudden today a twitter account was created by "authorize.net"? I highly doubt its actually authorize.net, this company is huge and has backups for everything, this will be on the news and I won't be surprised if they went under as an entire company. I'm starting to look for another permanent gateway and will probably use paypal until then.
Thanks for the insights! Yes, my friend's dad in Munich used to program the main software handling Hypo-Vereinsbank's transactions and it was all in COBOL (a previous programmer had introduced a small rounding error, which resulted in havoc... good story).

Very interesting to see this diversity of systems.

Bird Navigation Breaks Entanglement Record

It's really interesting. On the one hand, what a way to capitalize on your cred in the community. On the other hand, it's risky because it makes him appear desperate for money. In any case, I wonder if this could be a new sort of business model for the master developer.
I want to thank you all for the encouragement. I did not expect it. I thought people would say I'm too old and it is too late.
I would think that about 90% of Sailer's articles are too trollish for HN. (Consider the title of his book about Obama: "America's Half-Blood Prince".)

This article, however, made a very salient point, which I have heard from other people as well, particularly in regards to the conflict in South Ossetia. (Basically, he says that the American media is too sympathetic to English speakers around the world.)
Prisoner A is the one that asks. That sets the one an only perspective for the guards answer.
Your remark fails to consider that most successful entrepreneurs experience failure in their lifetime. It's part of the game.

If you want to follow many people you can't follow people who post frequently.

I think that's reasonable; surely professional tweets can be restricted to a dozen a day.

If twitter makes it possible to prioritize tweets that will change. But as long as everything is time-ordered, high-frequency tweeters interfere with my ability to follow high-priority tweeters.

i'd say it's a lot more likely it was killed because of the political slant. very few political articles are allowed to live around here, because they lead to divisive and unproductive arguments.
This is great -- I hate having compiler/runtime advances in Mac OS X always tied to the latest platform release. It can take years before your customer base upgrades, leaving you unable to leverage what I'd consider basic language features -- like fast enumeration, or now, closures.
The tech industry is really passive-aggressive. Angry diatribes, pizza theft, blog posts... if some guy dumped beer all over my laptop on purpose I'd just put him on the floor, like a normal person.

Limewire profits from other people sharing stuff. These guys profited from pizza. Neither group asked where their respective stuff came from. Doesn't seem too hypocritical to me.

The silicon just won't go any faster. What do you want the electrical engineers to do? Moore got you hooked on his junk and now his supply's been cut off. People tried to switch you to something more sustainable, i.e. anything but x86 and C, but you couldn't wait for your fix.

A real hacker should be happy that there are fresh new problems to solve. Or, if you just want to get shit done, use a dynamic language and be glad that CPU speed is rarely an issue any more.
* You want traffic for your blog.

* Either you can take a risk and attempt something insightful, or you can stick a superlative after a number, which always works.

* Today you're feeling ambitious. Let's go for 20. There are 20 brilliant laptop concepts out there, right?

* There aren't? There're only thin laptops, urban laptops, stylish laptops, and big laptops that aren't really laptops?

* Oh, well. Every laptop designer has come up with a superthin laptop idea. Use all of them. They're all mindblowing.

* Write a few sentences if you feel like it. Sometimes you can even write that you don't like the laptops you're presenting as mindblowing.

* Submit your blog post online for SEO.

* Make sure that in your profile you identify yourself as a New Media feller:

"My new blog redefines what many misunderstand, SEO."

* Learn to ignore the complaints from people who think there ought to be more substantial posts.

I would say profit, but that web site doesn't have advertisers yet, so really it's more of a feel-good process.

albeit not in the "hundreds of thousads per day" ballpark

Hundreds of thousands per day is incredibly low.
Zynga is the largest game developer on facebook and they claim something like 13 million unique dailies.

Facebook is one of the stickiest (the stickiest?) sites around, so i'm sure its 10 - 20% a day of their userbase. For many people facebook has become as integral to their daily lives as pressing the start button on windows.
Ask HN: How would you fix healthcare?
1- My 1st simple solution would be to go out on a worldwide hunt and hire doctors in third world countries. Some would move and work in the US for less than 40K. Cost goes down.

2- Another option would be to simply send medical school students abroad to study in countries where they will be spending only a fraction of tuition cost in the US.

3- Hire a bunch statisticians and mathematicians to come up with the ultimate tailored-contribution-model, based on income/living costs.

4- "Government ran gyms".

How would you fix the growing healthcare problem?
When's the last time a design concept actually turned into a design? Concepts are essentially waste-of-time pornographic images. Look at the old design concepts that claimed they'd be here by 2009. To quote a favored director: "Total fucking bullshit."

The last thing I saw that remotely resembled an interesting "concept design" was when Apple told a bunch of people they were making an iPod phone with multitouch, a full-featured web browser, cover flow, and on-the-fly Youtube access, but that wasn't a concept design, that was a product unveiling, because Apple doesn't do concept designs because Apple thinks they're bullshit as well.
We are in agreement. I reread the last part of your initial comment and I see that I somehow misread it. My apologies!
I wanted to understand the factors that led to a particular outcome: Python becoming the de-facto winner for scripting applications.

I compared to Ruby, because that's the language I would choose for scripting, based on the ability to create nice internal DSLs.
It says in the first sentence that "It’s been just under 90 days since Facebook announced it has crossed the 200 million active user mark."

It also says the US has over 70 million active users.

Read the article.
It's always kind of funny seeing people who work with interaction design messing up the format of their own writing. In this case, I don't think it's the blog theme. I think it was his choice not to have line breaks between his bullet points.

I've gotten some weird looks and a few questioning words from Limewire employees at parties in their own office, like I was some riff-raff that drifted in from the street. Ultimately, however, they always gave up the inquisition and went back to trying to impress girls and/or lure them into the lounge room. Fantastic roof deck though.

I know some of the engineers and they're incredibly nice guys, but the company has been flooded by those typical business types.
Interesting article.

I wonder about parts of it:

> Various scientists have pointed out that photosynthesis and bird navigation must rely on quantum effects ....

After looking at the 2 linked articles (links are just after the above sentence in this article), I would say the word "must" above is incorrect. In both of the linked articles, researchers are speculating on quantum effects in bird navigation & photosynthesis.

Also, it seems odd to talk about "rely[ing] on quantum effects". If quantum mechanics is the way the world works, then everything is a "quantum effect". It's not like the universe has quantum parts and classical parts (is it?).

EDIT: Let's make that a more serious question. Is it?

I have no idea why the author has decided to crowbar their own bias on platform preference into this article. There doesn't appear to be any information that states its the platform at fault.

Wow, I can see the shopping complex where this happened from my window, and I'd noticed the helicopters circling earlier. It sounds like a straightforward robbery gone wrong so far, but I don't think there is any concrete info yet.
You offended me, by suggesting that Michael Jackson posts can all be easily grouped together. This one was fascinating and in-depth.
Or if you want to remain anonymous.

Remember the internet?
Thank you for providing this information. So, it would be something like "new high-optimized, dramatically improved, much faster build of the OS 3.0".
I doubt the kind of following Apple has - people spending thousands of dollars on its products, sticking with them even when their market share was marginal etc - is comparable to people regularly reading a blog.

So far, other "A list" web celebs ventures have shown that, after the initial hype, they succeed or fail based on their product's worth.
There's a couple issues here: this would be fairly difficult, as you'd need to change the DNA in probably several billions of cells before any phenotypic change could be effected. Perhaps one mechanism may be to engineer a retrovirus that would rewrite portions of DNA. This could obviously have far more important impacts as well: such an RV could reprogram cancerous cells to die off like proper cells, or disable their angiogenic capability; and of course it could be programmed to rewrite genes implicated in diseases like sickle-cell anemia or multiple sclerosis.

Another issue is that while genetics of course plays a role in behavior, I think it plays out more in directing the development of the brain, not the actual millisecond-to-millisecond activities of it. Based on my ankle-deep knowledge of neuroscience, I think that adjusting the DNA is unlikely to cause an adult brain to rearrange itself in such a way as to modify behavior. A more likely use for it could be in adjusting brain chemistry, which I'm guessing can have dramatic, if not entirely targeted, effects.
Open web standards are the way to do this.

Hell no. I'll take a specialized client with security from end-to-end, thanks very much.

"In four years, Michael Arrington has gone from knowing relatively little about the Internet..."

"In 2000, he co-founded Achex, an online payments company, which was acquired the following year by First Data Corp. for $32 million. He also worked at a startup in London, founded and ran two companies in Canada, and was chief operating officer at RazorGator, a ticket reseller."

After taking time off, a friend suggested starting a company and, in an effort to educate himself about the Internet..."

So he didn't know anything about the internet but somehow started and sold a web payments company and was later COO of an online ticket company?
Thanks, fixed. I wrote it inline and decided to modify the signature, but forgot to drop the variable.
The title is kinda misleading. The Javascript timer optimization he is talking about doesn't require HTML5.
The problem is that if it can be proved that P=NP can't be proved or disproved, that constitutes a proof that P!=NP, since it proves that you won't ever come up with an algorithm, which is what the question is really about in the first place.

This being math, one can imagine ever more finely sliced arguments being made, but a "simple" proof that P=NP is forever unsolvable is itself a proof ("the probability that we will find such an algorith is 1 in 10^100"), for all practical and most theoretical (though not all) purposes.
Sounds good, i'll show up. http://www.yelp.com/biz/eddie-rickenbackers-san-francisco
got your point actually, you can see all the data here: http://db.lloogg.com, there are many stats about load, disk I/O, and so on.
It doesn't necessarily take any longer to live in the moment. It's a matter of where your mind is focused. In fact, if you are focused on what you are doing, you will likely be more efficient and make fewer mistakes. If the task ends up taking longer, it would only be because you did a better job. That is, you might be able to rush through washing the dishes with your mind on the future, but your dishes would still be dirty.
When Einstein asked Chaplin under the glare of klieg lights what it all meant, Chaplin replied, "Nothing, absolutely nothing."
I've never heard anyone, "religious right" or otherwise, complaining about the use of adult stem cells. The problem people have is with embryonic stem cells gotten by killing embryos, and thus not from your own body.

So, again, I don't think anyone has any problem with the procedure described in this article. And certainly there are no unusual legal restrictions on it in the U.S.
We told you it's not good for HN by flagging it. We're disagreeing with you, because we believe it doesn't belong here. Now you come here and presume we disagree with the contents of the article and suggest we are morally inferior, because we have unethical reasons for flagging the article. You're not just wrong once, but twice.

What is the political slant of that article?
Yes, and thank you for reading the article. It is an interesting and important point.
No, the article was auto-killed. The blogger is probably blacklisted for being racially insensitive or something. Yet here is an example of one of his posts that did well on HN and generated much interesting commentary: http://news.ycombinator.com/item?id=280544
Either there is a polynomial-time algorithm for SAT or there isn't - no middle-ground here.

Statement of the continuum hypothesis: There is no set whose cardinality is strictly between that of the integers and that of the real numbers.

You can provide your argument against the continuum hypothesis. No middle ground? There might not be a polynomial-time algorithm for SAT... but how would we know? You might not be able to prove that one does not exist. The absence of evidence is not the evidence of absence. And we could be eternally locked in this state.

Middle ground exists, for constructivists, those who don't admit the law of the excluded middle (that any statement must be either true or false). And I think most theoretical computer scientists are of this persuasion.
Option 1 although good it probably won't fly well. The first step to cleaning up the existing mess it to stop rewarding doctors based on the number procedure they apply on a patient to cure them in medicare. That is probably the most insane healthcare practice and I don't think it is done anywhere else in the world.

Once the doctors realize that these current practices are not sustainable they probably will come out with some novel ideas like this one http://hbswk.hbs.edu/item/4585.html.

It doesn't really make sense to have only for profit health insurance companies, look the executive salaries (http://www.prwatch.org/node/8425#comment-4517). With the amount of money the US government is spending on healthcare it would make a lot of sense for us to have a single-payer system.
Without diving into the code, can you tell us the algorithm? Does it scale based on upvotes? Such that a 200 vote story is harder to kill than 70? Or is it just that once a story passes 50 upvotes it can't be programmatically killed?
