Why can't you do the same study from the bandit results? From what I understand, this the same as A/B testing, except it will only show a suboptimal result to 10% of the users instead of 50% (or more). After a few days of testing, can't you take a look at the statistics and analyze them the same way that you would for an A/B test? Then just stop testing?

The A/B test just gives you the conversion rate of each option. And so does the bandit. As I understand, the only difference is that the bandit will be bugging your users with bad results less often.
My bias, I guess, is growing up with the sound of gunfire on a daily basis from family and neighbors. I didn't really think it was a big deal - just became part of the background noise. The concept of "Gunshot detection systems" just seemed ludicrous to me. I didn't actually realize until I googled a bit that it actually _was_ illegal to discharge a firearm within certain city limits - I would have argued (and lost) that the law was "negligent discharge of a firearm"

I guess if it's illegal to do so, then a "Gunshot Detection System" has use. In the same way that Red Light cameras and Speeding Detectors serve a function in managing those laws.

There are lots of places in the Bay Area where you can safely discharge a firearm within city limits. At least I know I need to review the various city/municipal bylaws to see whether it's legal.

I think he's referring to the 100 year anniversary of the initial commission.
First i wish to say good luck to your family, i hope you can find something.

Ok here's a guess:

Assuming missing deglycosylation and N-Glycanase's involvement in ERAD (endoplasmic-reticulum-associated protein degradation), perhaps there is amyloid fibril formation due to faulty protein degradation?

If yes, you may want to try out green tea or some kind of extract from it, in particular Epigallocatechin gallate sounds interesting. Besides antioxidant activity (which i guess could help with excessive glycosylation causing an oxidative environment), EGCG is thought to help in various diseases where protein aggregation plays a role. You can find lots of papers on this if you search for "epigallocatechin gallate amyloid" on Google scholar. I'm not a doctor, just a grad student (thanks for the guide!), so you should check with one first if that makes sense.
That is the coolest thing I've seen in a long time. Can't wait to see how this will be used.
For some people this would work well, and when you do know a lot about your condition, it is very annoying to have to deal with doctors who have to come to and verify conclusions that you have already made.

I have a pretty dense medical knowledge compared to the average person. My mother had a lot of medical issues that I studied in detail. I have several of my own that I have also studied at great length, and I used to be an EMT. Waiting around and going through a tedious process for a new doctor to "catch up" with you is frustrating.

A lot of people aren't like this, though. I have a friend who, after weeks of not feeling well, had, at one time, read pages and pages of research on a particular disease and had convinced herself that this was the thing she had, this was why she was sick, and this was what she needed treatment for. What she failed to neglect was the title of the paper -- she had diagnosed herself with kennel cough.

As much valuable information as there is available on the internet, I also feel like the internet breeds hypochondriacs like nobody's business.

So I don't really think we need a change in the way healthcare is delivered, exactly. I think what we need is more education for would-be doctors about how to better engage and involve a patient in their own care and how to talk to a patient sincerely about their condition and evaluate the people who just googled something vs. the ones who genuinely know what they're talking about, and then how to work with the latter.

Good doctors will do this naturally, but a lot of doctors will take the attitude that they are the doctor, they know best because they have been to medical school. They may well have a better overall understanding of things, which can very well be extremely important when looking at how diseases and medications interact in conjunction with and affect one another. However, there simply isn't enough time for them to become experts on everything. There should be more emphasis on this fact and more instruction on how to work with the patients to make them the experts so that they can be more involved in their care.

I feel like I'm not making my point well, but this is starting to ramble a bit, so hopefully that makes sense.
> No organization with the word 'freedom' in their name should be actively trying to take choices away from consumers.

What organization are you talking about? The Electronic Frontier Foundation wrote this article.

On the off chance you're referring to the FSF, the Free Software Foundation wasn't even mentioned in the original article, only in an update about a tangential issue.

Deformable physics like that isn't much of a problem if you only have one vehicle in an empty world on the most expensive consumer-grade hardware.

CryTek are showing off their own physics engine here, that's the big news. There's nothing too special about their physics engine over others, it's more about the pipeline and the amount of work needed to create a soft-body vehicle.
I've spent a bit of time waffling about writing this. I hope I'm not crass.

There's a major problem with incentives in attracting people to research. Why should supply and demand behave differently at universities? I believe that research is an example of the tragedy of the anti-commons.

If I were to jump back to computational biology my lifetime wages would conservatively decrease by $5 million, non-inflation adjusted. Many people are unable to accept lower wages for more interesting work. The wheels of scientific progress will turn slowly as long as it is the sole realm of those able and willing to accept substantial economic sacrifices.

I want to help, I'm just not able.

The word itself is basically a joke, sure, but it serves as a nice accumulation of letters that have a somewhat unexpected pronunciation, certainly a feature of the English language. Pronunciation and emphasis are pretty hard for non-native speakers, and the written form doesn't help that much. On the other hand of the Latin alphabet spectrum, there are languages like Vietnamese, where you've got a boatload of accents and diacritical marks to help with it.

Although I'm not sure whether describing Perl as the Vietnamese of programming languages would be a good selling point, so I'll stick with French ;)

The gyroscope keeps the vehicle from falling over when stopped. Even without regenerative braking, thats pretty necessary complexity when you can't stick your foot out to add a third point of contact.
On a side note, the use of infographics in situations like this really annoy me. There is no data involved, no visual elements, only six things involved in a two column list. It sacrifices readability on small screens and scrapability by search engines.

You're entire rant against rationality is misplaced. "The only objective truth is that there are no objective truths." Please. You may argue that your feelings of love and devotion as a parent are irrational in nature, or even that they're somehow outside of the realm of time and space, but that is neither here nor there when talking about whether parenthood is so consistently fulfilling, irrational or not, to the point where we should recommend it for everyone.

I talked to one of the guys in the Lit tent, and I remember him saying that they were aiming for the mid teens as a price point, and that they were planning for a higher capacity vehicle that was closer to the price listed in the article. I wonder what changed in the last 10 days.
Compared to what I need and what I'm willing to spend for the features the product offers. It fals short of what I need a desktop to do, so that means it's better suited as a TV-connected device. But the GoogleTV does much of what you'd want a Google device that's connected to your TV to do and only costs $100. Alternately, many TVs will offer GoogleTV integration if that's what a consumer really wants. Or, if you've got an Apple ecosystem of devices in your household, the AppleTV and Mountain Lion will likely offer you better connectivity for that content. If you're a gamer then an XBOX360 and the myriad of supported streaming services it now offers (Amazon, HBO, MLB, etc.) can stream the most-common services to your TV. But let's say your desktop computing needs are different than mine, and you still want a desktop PC. A cheap Inspiron offers all of the Google browser-based services PLUS you can run all of the Windows applications too, so why not go with that instead? You can get an underpowered device that can do basic desktop stuff for less than this costs, or if your needs demand it, you have the option of adding better hardware to meet your specific needs.

Agreed. There is plenty of awful perl code out there. I have worked on codebases that did things like:

some_func(\%$some_object, \%some_hash);

and used variables like $a and $b as mainline code parameters...

However, if having dangerous features were something to hold against a language in general, nobody would be using C (maybe Linux in such an alternate universe would be written in Fortran or some other abomination). On the whole, I think that well-written Perl is very good. Poorly written Perl is... well, poorly written.

I was surprised when I installed Fedora 16 how well Xmonad integrates with Gnome. It comes with a Xmonad-Gnome session that has the advantages of both worlds (at least for me).

"After a few days of testing, can't you take a look at the statistics and analyze them the same way that you would for an A/B test? Then just stop testing?"

No, because the assumptions that underpin many statistical techniques are violated when you're not assigning people to cohorts consistently, and at random.

Ask HN: Asp.NET MVC3 tutorial like Learn Rails by Example
Hi everyone, for work I'm going to be using C# and the .NET MVC 3 framework. I have some experience with Python, Ruby, and RoR and working on Linux but not much experience developing on the Windows stack.

I got provided a copy of Visual Studio 2010 Professional am going through the tutorials on asp.net but am wondering if there is a place or a book where I can really learn about the .NET MVC framework.

If I wasn't clear I'm happy to explain further! Thanks!

Perhaps this isn't the place for the question, but I'll ask anyway. Is there any JVM-based language that excludes any code from being compiled that is not directly implemented in that language? For example, any code that would deny the use of java.io or java.lang?

The reason I ask is because Clojure and Scala both suffer from the ability to call legacy code. While some think this is a good idea, it makes the whole scalable, safe/functional paradigm completely unstable. Is there any language out there that forces the developer to use only things written in the specific language its since that would be the only safe platform?
> The function of the rule is to prevent people from creating an alternative app platform. For example, one based on the Flash runtime where you could download new applications from within this app, thereby bypassing the app store.

A full-fledged third-party browser would inevitably be an alternative app platform. In some ways, that's the point.
> Deserving freedom and deserving free aren't really the same thing though. The FSF is not about entitlement to something, but rather about human rights, or applying the basic principles of trade to software too.

Agreed - I was being mostly tongue-in-cheek, and playing on the fact that anything that is expressed as a 'right' implies some sense of entitlement... of course we're 'entitled to our rights'!

Though you're correct that the 'right' to freedom is also justified by the principles of trade as well.

Using a decent burr grinder + AeroPress has completely changed my coffee drinking habits in the past six months in that I almost exclusively make coffee at home versus buying a latte somewhere. I also switched from the normal AeroPress brewing method to the inverted method described here:

http://www.boldbeancoffee.com/learn/brewing-guide/aeropress/

In the Bay Area, I've found that Philz has very good beans for the AeroPress. Barefoot and Blue Bottle beans are also good, but they both seem to be a lighter, more acidic roast than Philz and less to my taste.

The AeroPress is not exactly effortless (it takes a few minutes of activity to produce a cup of coffee), but there's something profoundly relaxing about the ritual for me.
I have an Xbox 360, I actually like it a lot.

All these nice capabilities are available now on the Xbox, Twitter, Facebook, Netflix, Amazon Instant, Hulu, etc. Even some cable companies are offering the use of the Xbox as an IPTV device for their own service, including Comcast last I checked.

Naturally you have to pay for each of those separately, for those that require a fee. No big deal, they're already separate services that just happen to work on the Xbox, just like some of them work on my Roku, or my Apple TV, my iPhone, my iPad, or any number of other platforms.

However Microsoft appears to be the only company charging me, the owner of the box I bought from them, and the user of those other services I already pay for, for the ability to use them on their platform.

All those things stop working, even Twitter and Facebook, if you quit paying for Live Gold, and that's actually the primary motivation for a lot of people to pay for it month after month, because stuff stops working on the box if you don't, stuff that Microsoft isn't even in charge of running, stuff that you're already paying for.

This is part of a larger class of problems known as reinforcement learning problems. A/B testing when used for decision optimization can be thought of (sort of) as just a form of bandit using an epsilon-first approach. You play random until some threshold (using some sort of arbitrary hypothesis test), which is the learning period, then you exploit your knowledge and play estimate best option.
Epsilon-greedy is nice because it tends to work well regardless, and isn't completely affected by drift (nonstationarity of the environment).
One heuristic to use for deciding between using a bandity approach is to ask , is the information I will glean perishable or not pershible? For perishable problems the opportunity cost to learn is quite high, since you have less time to recoup your investment in learning (reducing the uncertainty in your estimates).
Also, finding the optimal answer in these situations may be less important than just ensuring that you are playing from the set of high performing actions.

The willingness to involve new contributors can be even more important than how they reject contributions.

On a few open source projects I used, the lead developers spent a lot of time on the mailing lists but weren't that open to bringing on new developers. I understand if a developer on a project doesn't have time to add a new feature for you, and I even understand if they spend more time than they should providing support while their development slows. But if after all that if they still are not open to new developers joining the team, or make them go through ridiculous hoops and excessive process for the size of the team, then they should understand when the project fails.

I take issue with

Haskell programmers may be familiar with this as a do
block, and for Schemers, this is the equivalent of a
begin sequence. However, unlike Haskell, in Loop, a
sequence is guaranteed to execute in order.

A do block is syntactic sugar over >>= (bind) and is monadic in nature. And the IO monad (which is relevant to the example that involved printing things.) is a construct which guarantees that the parts will execute in order. That's kinda the point. That he got it wrong makes me not trust the language. He shouldn't claim to have been "Inspired by Haskell" if he doesn't really know it.

Also in Haskell the pattern [x:xs] matches a list with one element, which is a list with at least one element, so [[1,2,3]] (== (1:2:3:[]):[]) gets matched with x = 1 and xs = [2,3]. That differs from loop's pattern matching. But [x] still matches a list with only one element. What does [x:[]] match? If you are going by [x:xs] matches [1] with x = 1 and xs = [], then surely [x:[]] will match as well.

Also, if you are making a functional programming language, you know one that uses recursions instead fo for loops, why do you call it Loop? I didn't see one loop in any of the examples. It's just silly.

EDIT:
Oh, and if Nothing really is a subtype of everything, then 5 + Nothing should typecheck right? Not " It is a type error to attempt to compute with Nothing." Since Nothing is a Integer, since it subtypes everything. I don't understand. Is + special in hating Nothing? Nothing.add(5) would return Nothing, right? So why not Nothing + 5. Oh, but wait, Nothing is a subtype of string, so Nothing + 5 means string concatenation, right? You did say a + b where a is a string casts b to a string, didn't you? It's inconsistent and I don't think it has the proper semantics.
