Not exactly the same, but my favorite visceral examples of imperfect heuristics are "garden-path sentences"[1]. These are sentences that trick you into having to backtrack when you're parsing them, which brings the whole parsing process into sharp relief.

A good example is:

The old man the boat.

Figure out why this sentence is actually grammatically valid and then read the article.
Economists do not all think that way. Just as there are many differing perspectives in other sciences (feel free to cringe if you are a mathematician, chemist, etc.), there are a range of schools in economics as well. Though I cannot fully delve into the topic at this time, variance is certainly taken into consideration by many economists. Depending on the situation, (number of betting cycles etc.) variance is very important. So, in a one-off bet, it makes sense that the utility between these choices would differ.

I tried to find a good resource that further explains this but wasn't able to quickly find one. If I am able, I will try and post one later today.

On a final note, all of the situations in this quiz are easily correctly answered (or in some cases, predicted) with a basic knowledge of statistics and economics.

Teachers do not do this now. They have a specific book or set of books that almost all of the time is required to take the class.

The problem is it's a requirement and they often test directly from the book because it removes effort from teaching to the test.
I actually find it very useful to emotionally detach from a commodity - that is treat all tickets to the movie theater as the same. I generally find it bad to fall into the sunk-cost effect and I am much happier when I avoid it.
We used Gamecenter because me and my partner didn't really have the expertise of setting up the server side that would be required for an app like this, so we decided to let Apple take care of that for us. We also didn't want people to have to make new usernames and passwords and have to find their friends again in a new service.

Thanks for those, I will keep all of this advice when we are ready to submit the next update.
When you tell your guest to leave, and they won't, or they don't have anyone to pick them up, and you wanted them gone, you would forcibly remove them from your home and place them outside.

I am with gcarswell on this one. +1 to her!

I don't think search is an easy problem. And (where it is not conflicted by self promotional interests) Google does an amazing job of indexing, filtering & scoring.

It is nearly unbelievable how good Google is in many areas. But that is also the problem...Google set the bar for itself rather high through its own performance.

A gold medal sprinter doesn't get a pat on the back for running a 23 second 100-meter dash.

When most companies put out a product they have to make it better than existing products to win marketshare. They can't put out something sort of average and then just arbitrarily promote it in the results through bundling (the way Google has with things like Checkout, places, product search, flight search, and +)

In the past Google did a much better job at search when it wasn't actively subverting itself.

If I searched on Google 3 or 5 years ago I didn't see Avis-rent-a-car ranking near the top of the search results for "Las Vegas hotels" ... it was only after Google decided to displace & monetize the organic results that Avis started ranking on hotel searches.

http://www.seobook.com/images/hotel-price-ads.jpg

And who's fault is that?

Google's.

If the monetary incentive wasn't there, I am sure Google wouldn't be polluting their own search results, especially as they have put thousands of man-years in trying to do the opposite.

~~~

I also think the suggestion that a person should switch their default search engine is a bit inauthentic for 2 reasons:

1.) Google is spending BILLIONS of Dollars per year buying search & browser distribution + buying default search rights on 3rd party browsers

2.) even if I change my default search engine that personal choice wouldn't impact how other users search & for those other users the copy of copyright content hosted on Google.com will often still outrank the original source.
The advantage is you don't need to know the channel characteristics ahead of time. In particular, if you used a Reed-Solomon code, you'd use one designed for one particular erasure rate. But that code would be too weak for a channel with a higher erasure rate (it would fail to decode) and it would be too strong for a channel with a lower erasure rate (it would be wasteful and use too many parity bits). The advantage of fountain codes is that they work efficiently whatever the channel's erasure rate.

By the way, I've been talking about channels with an erasure rate (the Binary Erasure Channel) because fountain codes were originally invented in that context. But you can find in the literature papers on "Rateless codes for noisy channels" that show that the fountain codes also work fine for bit-flipping channels like the binary symmetric channel and the additive white Gaussian noise channel.
Isn't it possible for the user who uploaded the content originally to file a DMCA counterclaim, at which point the content can go back up until a traditional court case finalizes the issue?

It's still (IMO) a bad piece of legislation that is being abused, but it's not as bad as putting the complete burden of proof on the accused.
Minimal viable product for the people, by the people
With the recent passing of the NDAA bill and SOPA making it's way through the House, our civil liberties are eroding away.

In order to change direction, we need to start at the local and state level. Most people don't even know who their state representatives are.

If there was an easy way to be notified when your representatives were signing a bill, giving a speech, or anything related to "representing you" - in which they go against civil liberties, wouldn't you like to know about it? And be given a way to respond as a group?

What I need is a Minimal Viable Product to see if enough people would sign up for something like that.

It would be similar to http://www.codeyear.com

The MVP should just be a simple landing page, and only specifically for San Francisco. It would just contain an email input form and some wording such as:

-----------------
Want to be notified when your representatives do something that goes against civil liberties? Enter your email and we will send you the most important alerts, no more than once per week.

----------
That's terrible copy, but you get the point.

Is anyone interested in testing this MVP out?

Ask HN: Open source Flickr/FB Album alternative?

Ugh. This seems a perfect example of why selling to a market composed of people you'd find on HN isn't worth it. No offense, I'd probably use AppShopper too and feel similarly, but let's face it, the vast, vast majority of iOS buyers aren't going to scrutinize the price history of your app before purchasing. Why are we programmers the whiniest group of users out there when it comes to buying something that costs less than a cup of coffee, and probably literally is worth less of our time than what it took to look it up in AppShopper?

Yes, however there is a slight chance of winning the odds and not paying anything. The risk is minimal. If the numbers were further apart I don't think the same logic would kick in.

A = $900 lost
B = $9000 lost with a 90% chance

Those are odds I wouldn't want to try. I would take the instant loss knowing that my odds are just not good enough to win if I were to choose B.

First Look at Kepler SETI Candidate Signals
I have run my own servers in a datacenter for 7-8 years and going to a VM setup was the quantum leap. I can copy and paste a server in minutes and be up and running with a nearly identical setup that I have to setup for my dev environment anyways.

Hardening the server is something that can be outsourced for a lot less than thousands. Services like linode seem to be a nice middle ground. While I don't see myself going back to my own hardware in a rack i run in a datacenter, I do still see the benefit of knowing your stack a bit beyond coding. Knowing how the stack works helps when building software quite often.

Anyhow, those are just my experiences. VPS' with a very strong toolkit to take the edge off self-administering like Linode, etc, seem to be a very nice option. Heroku has caught my eye too but they have completely different measurements.
Our interviews are never in the office. They are at a restaurant or bar. We just have drinks and food with them and chat. Talk about technology, them, us, etc... If we can have lunch and drinks with someone and they are talented then they are a good fit for the team.

The lunch/bar setting also loosens the interviewee up and they are always less nervous than if we had brought them into the conference room.

We don't care how talented you are if we can't stand being around you. If we had to choose between a mediocre programmer who has a lot of passion and fun to be around or a brilliant programmer who is arrogant, we'll take the mediocre guy and just train him up into being a brilliant programmer.
If you correctly architected your application around the constraints of AppEngine, then it wouldn't be costing you a lot of money. That is the whole point... you know the constraints, so you architect wisely and you spend money where you need to. You decide which indexes you need and which ones you don't need. You decide how many reads and writes you are going to make. You figure this stuff out in advance and if you make a mistake, you refactor your code to improve things.

I'm not saying it is easy, it isn't. It takes a skilled engineer to learn this stuff and make it work. But, when it does work, it really does work.

It sounds like you failed to create an application that took all of that into account and of course you are going to look 'real stupid' when your clients figure out that you took shortcuts. There is no way that could be the fault of AppEngine.

I'm curious where you went after AppEngine. Are you hosting on AWS now? Heroku? EngineYard? Do you have the same reliability and scalability as what AppEngine provides? Maybe that isn't something that is beneficial to you and in that case, I can see how AppEngine is not your cup of tea.

For me, AppEngine is amazing. I love the fact that I'll never have to hire a sysadmin. I love not carrying a pager. I love knowing that when my site gets an asston of traffic, I won't ever have to think about making it scale. I love not having to worry if my database is on big enough hardware, replicated across data centers, backed up. I'll never have to think about whether or not my OS needs an upgrade to plug a security hole or ssh'ing into a server at 2am to figure some esoteric problem out. To me, all of these things are worth the 'cost' of AppEngine. I'd rather spend my time adding features than doing sysadmin.
Ignoring the technical aspect, I really like the aesthetics of the UI. It's a nice break from the usual 3D mac-style apps that try to emulate shelving or books.

We tell them "Write this how you would write a real world application". We don't care if it is OO or functional or whatever... We just care if it is well designed. We don't tell them to write tests but if they don't then that means they don't write tests in the real world either.
I'm glad you mention you build apps. I (finally) get that piracy isn't the real issue as far as music and movies are concerned. I see how they can make money despite copies of their work flying every which way for free but I don't understand how a software developer can be against copyright. It's one thing if you're all about the GPL and FOSS but those doing it as a living surely can't see sharing as a good thing, can they? If you're on the apple app store it's probably less prevalent but generally speaking, how can software developers make any money if they can't enforce copyright? And remember, not all software lends itself to the support model like ReD Hat.

I'm really torn. On the one hand I'm almost converted on the music and movie side of this but can't get on board because I still feel it hurts software developers. How does this not bother you?
Importance of a software development company in website building 
Whenever you go to expand your business over the web, your website would be the best recommended way to keep in touch or to get limelight over the web. For developing the website for your company, you can hire the services of any of thesoftware development companies, across the world.
Reed-Solomon and similar codes correct for bit errors in a particular block by transmitting extra bits in each block. Fountain codes correct for missing blocks by transmitting extra blocks.

If you just used RS, the only way to overcome really long bursts of errors (thousands or millions of bits long) would be to either to request acknowledgements from the receivers and retransmit unacknowledged blocks. If acknowledgements weren't possible, you would need to transmit everything multiple times. And, if you had enough receivers, all missing random packets, you would end up retransmitting everything even if you had acknowledgements. By using fountain codes, you can transmit an extra few percent of blocks and still succeed in the face of long dropouts.
"Investing in good developers is such a good bet at the moment, that if you have money and you happen to find a talented developer who seems to like you and wants to work with you, you should give him/her your money to build something, anything, even if you have no really good product ideas (those are cheap; I’ll sell you a dozen for a dollar)."

Wow. Great article. This made me understand some reasons why I am having such a great relationship with my current main customer.

After doing a simple web design job for them to get my foot in the door, I negotiated a higher rate for a more complex project. After that, they quadrupled my rates, on their own. They then fed me more, smaller projects that were mostly to fatten up their product offerings.

Such a show of faith really won my loyalty. I was, however, a little mystified. Maybe it's low self-esteem, but I found it hard to believe how much they valued my skillset (I'm one of those "designgeneers").

This article helped to explain this: they've been feeding me work to keep me available, even if they don't really need it. Now a big from-scratch devel job has come up, and even though I'm working under my rates, I made sure to be available to do it for them. They've been grooming me for this job, and they did it in exactly the way this article describes.

I'm really grateful for being treated this way. I've been on the cusp of two industries for a while now, and this kind of positive experience has pushed me to the software side.

"Another reason is that software skills are the most portable high-end skills on the planet. Spotting and temporarily attracting talent doesn’t mean you get to keep it."

We're really starting to be valued. All in all, this article made me feel really good about my decision to commit to designing and building web applications as my main vocation.

45000 Facebook passwords stolen by Worm.
Had this recently happen to me a few months ago. They did three phone screens over two weeks but missed dates a few times. No biggy, shit happens... Said they were flying me out a certain date and then the day before said oops we didn't get approval, I finally get out there do a 4 hour interview and they forget to schedule me with the CEO even though I point out the mistake the day of the interview. They call be the next day asking to schedule that interview for the day after even though I'm now 2000 miles away. I said I'd be out there again in two weeks after my move. When I get out there I contact, contact, contact... No Response... They get back to me a few weeks later and I tell them to fuck off and there wasn't a chance in hell I'd ever work with them.

...and then they wonder why they can't hire anyone.

I can't tell you how many companies did shit like this, just not this bad, and I was interviewing for senior level positions. It's huge red flag.
>Content owners have to police the entire internet for their works.

See, here's the problem. That is highly unfeasible, if not impossible (not to mention unethical) and should tell you more about the brokenness of distribution as a business model than it tells you about the need for copyright protection.

Oh, and about most of the notices being legit: Google estimates that more than a third of the notices they receive - of which more than 50% are aimed at competing businesses - are plain and simply bogus.[1] I'm sorry but I don't believe the claim that most of them are legit. And even then, such a high number of "false positives" are plain and simply unacceptable.

Oh, and there is still the thing about due process, which the DMCA completely eschews.

But in the end, it's meaningless to discuss this. I'll say it again: the DMCA is just one of the many useless tries to fight a symptom whose cause are the violent death throes of a business model that should have died nearly two decades ago. The root of the problem is still copyright, and as long as we cling to it we won't be able to find any meaningful solution, but keep trying to band-aid a leper with hemophilia.

Don't you want strong typing for better performance?
That's what I thought, too. The VM designers say that in practice, type guarantees really don't help them nearly as much as you might think, because type checks are not a major drain on performance.

No, but you can generate better code if you know exactly what types you're playing with ahead of time.

Say you have a function like this:

void foo(SomeClass obj) {
obj.bar();
}

That could be compiled to just a straight 'jmp SomeClass::bar', whether you're compiling natively or to a VM.

If you don't have static types, the best code you can output is something along the lines of this:

fn = lookup(obj, "bar")
jmp fn

Of course there are tricks that you can use to optimize this second case a bit that involve fancy static analysis, fancy JIT business, etc. but the point is that you will never generate better code than just a single jump to the right code, based on the types you know at compile time in a static language.

Unfortunately, the same kinds of companies love to do the same thing to "vendors".

Multiply the time wasted by 5x and throw in a 10-page proposal, and you have what is called the RFP process. Huge amounts of time wasted in writing, crafting solutions, meetings, and budgeting. And all for no response. At. All. That's what having your own development shop is like.

Great points.

The more I think about it, America would look very different if there was no copyright. There wouldn't be the huge companies that we have today. For example Disney has the sole rights to produce Mickey Mouse based products, but if anyone anywhere could produce Mickey Mouse based products, then suddenly a hole lot less money is streaming into Disney, and just take that effect and multiply it out=no more mega corps.

It would change the face of commerce and to that effect even employment, you'd probably have many more small businesses and a lot less "corporations".

In any case it would have very far reaching effects...
