I am not saying that your code has bugs (or that it hasn't!).

However running experiments to prove that one 'process' is superior to another in a real world situation often involves more than running a chi square test on randomly generated data ;) (which is what I understood your code to be doing on a very brief glance at it- sorry if I got it wrong).

There is nothing wrong with starting your exploration with something like this, but it really isn't sufficient to make the claims in the blog post about specific ways in MAB is better/worse than A/B testing.

This seems to be methodologically dubious. I am not a stats expert, though I use it in my work, and I could be wrong but testing convergence to statistical significance doesn't seem to mean anything (mathematically/statistically)!.

I could be wrong - there are people with Stats PhD's here and I'll leave it to them to tell me if I am. But I've never heard of an experiment (in the formal sense) which ran till a significance checking algorithm crossed some tripwire level.

Is the sampling random? (especially for an MAB) What are the underlying distributions (and assumptions about them)?

In your article you (imo) either need to say something like "this test isn't really valid and so the conclusions shouldn't be taken very seriously" (which would be weird thing for a company with your product to blog!) or you should do some rigorous experiment design and be able to defend your results.

Right now it reads like some MBA type plugged in two black box formulae in an Excel sheet and drew conclusions from the results. (please note: I am not saying you did it that way -just saying that the article reads like not enough thought went into setting up a proper experiment)

(Statistical) Experiment Design is a lot of work and surprisingly hard to carry off well, and involves much subtlety - and theory! there are whole books written about it. Maybe time to buy a few? :)
Of course it wouldn't deter a someone with skill but it deters a bunch of people from googling how to use Reaver.

Why Play Station 4 With 2GB RAM Makes Sense
You are changing the subject a little. The burden of proof for a strong and controversial claim is still on the person making the claim.

I haven't made any claim about what the Iranian revolution is doing, so I don't know why I would be obligated to show you evidence regarding what they are doing. Nobody else really knows what they are doing, that is the nature of intelligence secrets in Iran and everywhere else. If the general public knew, they would not be intelligence secrets any more. That is not license for inferring whatever you want to see.

I'm certainly not carrying water for the Bush administration's attempt to legitimize 'tactical' nukes (which accounts for the entire substance of your links, as far as I can tell). On the contrary, I strongly oppose that idea. But saying stupid, obnoxious, unwise things doesn't amount to a material violation of NPT. If it did, then there would definitely be plenty of hard evidence against the Iranian regime, which routinely says things just as gob-smackingly stupid and undiplomatic and ultimately harmful to Iranians as Bush's best.

It seems that you have stereotyped me as holding a whole package of views that I do not hold, and implied that I am engaging in some kind of hypocrisy, simply because I asked for substantiation of a claim. But if I disagree with you on one thing, it does not follow that I hold all the views of your rhetorical enemies.

Cheers
> "security for the 1%." And it makes the rest of us less safe.

Actually it seems like the opposite. The chances that the government or other entity with a purchased exploit is going to hack you is very small. The targets there are the 1%.

If instead of being sold on the black market, the exploit is disclosed to the public. Worms can be written, your grandparent's unpatched computer could be taken down, and the overall impact on the average Joe will be much higher.

If this is true, we live in a truly depressing world. I don't understand the point of an interview any more. I sit down, lie to you for an hour, you Google the shit out of me, stalk me on Facebook. But if I tell you who I am honestly? Trash bin.
Thanks :) I use the free version of Google Apps with this domain for my email.

The best thing is that I'm de facto using the gmail web app, but if in the future I would like to change provider it will be a smooth transition, since my email address will remain the same.

The nukes were used at a time of ABSOLUTE WAR. Every major economy on earth was geared toward war; nearly all manufacturing capacity was put toward not being conquered by your enemies and dying. It's clear very few people understand what that means today, as it has been 70 years since an absolute war has occurred, in which the major nations of earth were fighting for their very existence.

Britain would have nuked Germany to save itself if it had the opportunity and the necessity to do so, and or to bring the war to an end and kill Hitler if the opportunity were there. France too would have nuked Germany to defend itself and kill Hitler if possible. Had the Jewish people been able to, they too would not have blinked at nuking Germany and trying to kill Hitler in the process.

Japan would have nuked the United States and the rest of the allies. Germany would have nuked everybody at their leisure to 'win.'

The Empire of Japan was an extraordinarily powerful nation. Their military technology was very advanced, and they demonstrated endlessly that they were willing to use it brutally in instigation of war. They slaughtered millions upon millions in their Chinese invasion. It took a very substantial portion of America's considerable industrial base to defeat Japan.

It took two nuclear bombs before Japan capitulated with an unconditional surrender. The first one wasn't enough, which more than proves they were willing to shed millions more lives to keep fighting. America would have had to invade Japan and would have killed millions in taking the island to stop the war.

America had nukes before everybody else, and if their desire had been to do so, could have wiped out every other capital and brought the entire planet to its knees, regularly nuking anybody that dared to twitch about a nuclear program.

America also could have allowed a war to proceed with the USSR immediately after WW2, and nuked the USSR repeatedly and instantly become the sole superpower.

And in the last 67 years, America has specifically chosen to not use nuclear weapons of any sort, despite the radical military advantage that it has possessed for most of that time. Nukes in Vietnam would have ended that conflict very quickly.

It's a tragedy that Hiroshima and Nagasaki were nuked. Japan instigated war, both in general in the Pacific, and against America. Japan joined with Nazi Germany in a pact to destroy the allies. It was absolute war. I hope nobody reading this today ever has to really come to understand what that means.

Panjiva (Cambridge, MA: right above the Kendall Ⓣ) - Full time, Intern, H1B

We're small, fast, and profitable.
Our mission? Make it easier to do trade across borders. Setting up a production line and looking for a valve supplier that won't flake out on you? Use us to search for suppliers (or buyers) of any goods that go into or out of US ports and see credit reports, corporate responsibility audits, and customs records. Then, use us to reach out to them, communicate, and close the deal.

We're looking for exceptional software designers and engineers who can solve hard problems and design beautiful systems for our users. As a designer, you'll need experience both sketching out concepts and building them. As an engineer, you'll need experience with full-stack web application development, both server-side and client-side: A given day’s checkins may include performance tweaks to our backend data processing pipeline, an updated multivariate landing page test, a parsing expression grammar for a new data source, upgrades to our deployment infrastructure to make better use of our CDN, or new parallelizing queries to make Panjiva search faster. We're growing quickly, so our ideal candidates are ready to grow and learn just as fast in order to take the lead on critical projects.

We work in ruby on rails, but will teach you if you're coming from another platform.

If you're interested, email me at andrew@panjiva with your resume and a link to something cool that you've made.
Concerning young love, there's the perception that the world practically begins and ends with your partner. Given that she was assigned a tragic and uncommon fate, would it be surprising to think that Feynman, or anyone, might be more vulnerable to accepting the "magical" explanation, that the energy/soul of this unique being left a telekinetic sign?

Its not just that you wouldn't, on average, consider a supernatural explanation. It's that the stopping of a clock at any particular moment is rare and the death of your first true love...is, well, also extremely rare. A scientific mind, under some stress, might cede to the supernatural comfort by framing it as: "well, the probability of those two events happening at once"...and this framing would be made even easier given the overwhelming acceptance of such an event being supernatural by a 1940s-era society
Did you really not notice that your reply is to a strawman you made up? The person you are replying to did not say anything about CS vs programming. He stated that most people who claim to be programmers can't do basic programming, and most CS grads can't do basic computer science. Incompetence is widespread on both sides. There was no claim that one side is more important than the other, yet your reply is almost entirely "you are elitist for thinking computer science matters".

Every programmer should be able to fizzbuzz. 95% can't. This is a problem. Every CS grad should be able to build a tree. 95% can't. These are serious problems.

1. Could you gist your Python code?

2. You do not indicate whether you’ve run enough simulations to attain a high statistical significance (over the meta- result that each campaign statistical significance has been attained)

3. Correct me if I’m wrong, but I don’t think A/B testing should be run “until statistical significance has been attained” because it foils the purpose of a statistical test, that is, you should rather define before hand a number of iterations, wait until they have been completed, and then check whether it gives you statistical significance

4. The purpose of the epsilon-greedy algorithm is that it can be run for very long duration without knowing which statistical significance is best because it will adapt the most commonly seen version of your site to this particular version (ie it is made to be run almost indefinitely, and will -- in effect -- automatically remove the non-working versions after a while!
This argument is wrong on so many levels.
In this case, because you are measuring conversion vs. no-conversion, the underlying distribution would actually be binomial. With a large enough sample size, it looks similar to a Gaussian distribution, but still slightly different.

Also, I don't see the problem of lack of independence. People are still randomly assigned to one of the conditions in the MAB scheme, people in one sample don't affect people in the other sample, and each person submits one independent datapoint. The problem is just one of unequal sample sizes in your two conditions, so when you make the comparison (in a one factor ANOVA, say), you lose lots of statistical power because your effective sample size is essentially the harmonic mean of the two sample sizes (which is heavily biased towards the lower number of the two).

You are the only one who said anything about brain teasers and puzzles. The parent lamented the fact that so many programmers can not solve basic programming problems. Fizzbuzz for example. If you can't write fizzbuzz, you are not qualified for a programming job. It has nothing to do with computer science, or brain teasers people googled, and everything to do with writing actual working code to accomplish a trivially simple goal.
I wonder why this is tolerated with iOS but when Microsoft implements it people get angry. I mean, sure there's the argument that you can't use a free open source operating system on your computer but you can't do it on your iPhone or iPad either.
The war itself isn't nearly as terrifying, but somehow the US government is finding it even easier to erode civil liberties now than it ever did during the Cold War.
Where in the world did you get the idea that Feynman had beliefs that are irrational or unscientific? Because I read the article and all I could find was sincere feeling.

The phrase "hardcore atheist" suggests that you may have some baggage that is clouding your view on what words like rational and scientific mean. They never meant that you can't love somebody or grieve. That isn't even a belief, and it has nothing to do with theological views.

Yes, I agree we should put the code on the post probably so people know what exactly was done. Yes, it is a quick and dirty simulation, and not a rigorous analysis. I hope someone more knowledgeable does shed light if the arguments have any fundamental oversights. The post is mainly meant for our customers who asked if MAB is "better" than A/B testing. It clearly isn't as both are meant for answering different types of questions.
The hypothesis is no more verifiable than a claim that our actions in this life determine our circumstances in the next one. Indeed, I have better evidence for an hypothesis regarding karma right here on HN.
Something like this would have to be everywhere. I know I always wait a few days, before sending feedback that something doesn't work for me and sometimes I just stop using features like that. The chance to fix something before users would even start to complain is priceless.

Like any doctor would say, the sooner you find out something is wrong, the better. And if nothing goes wrong, you have a huge cool display of how awesome your company is doing.

Beyond that I think the Metro UI is way more suited for administration tasks than the 'Start' UI. But we'll find that out won't we?

Err... while I'm not stepping in to defend the TSA, I think that to call the threat imaginary ignores recent history.
Try Inkflow. Works great and has a zoom feature if you need to write small.
This blog post is describing epsilon-greedy exploration/exploitation as applied to A/B testing. It's not really multi-armed at all, since the multi would imply > 2. The real beauty of exploration/exploitation is the ability to go beyond two simultaneous tests. Although they do show a test with three options, this would be far better if it emphasized the multi more.
This only applies to ActiveRecord, I wonder if e.g. DataMapper is vulnerable in a similar way.
