That's kind of the whole point of the research. Neoclassical economics assumes certain things about peoples' utility functions that aren't true. For example, even though you can ascribe utility to going on a date, there should be no difference between not going on a date at all and having to cancel a date you had expected to go on. Obviously people don't view things that way. Or, to use another example from Kahneman's work, getting a $5,000 raise out of the blue is perceived as very different than getting a $5,000 raise after your boss had told you to expect a $10,000 raise. Or, for that matter, after your coworker got a $10,000 raise.

From the standpoint of neoclassical economics, these outcomes should be the same, but clearly they're not. Delving into the psychology of the rational actor in this way is a pretty fundamental change in economics.
This lecture revealed an error in question 5.

The Vanity Fair article says "Kahneman and Tversky debunked Bernoulli’s utility theory, a cornerstone of economic thought since the 18th century. (Bernoulli first proponed that a person’s willingness to gamble a certain amount of money was a product of how that amount related to his overall wealth—that is, $1 million means more to a millionaire than it does to a billionaire.)"

But in the lecture, Kahneman stated no qualms with utility theory. Rather, he pointed to the application of the theory, where Bernoulli had assumed a gain of $1 million is equivalent to $1 million appearing in their bank account, with the mechanism being irrelevant. That is what prospect theory (and the associated question) debunks.
As long as there are no exclusivity agreements, there is no problem--the problem with cable, aatellite, et. al. are the barriers to entry, which don't exist in the streaming space. (The closest Netflix has is its device presence).
This question can be highly debated, but here's my take...

Yes, alternative TLDs are cool for us nerds, but it's horrible for any startup in the consumer internet space. Most "regular" people are not familiar or comfortable using them. More often than not, people will meet you with a blank stare when you tell them your website is example.io.

I once spoke with the founders of Vol.ly (since acquired) and they said their name choice was a nightmare. Their company was pronounced Volly, but every time they would have to take time to explain their domain was v-o-l dot l-y. This is annoying for the founders and instantly forgotten by the user.

There's a reason why most startups that begin with non-.com domains eventually switch if they gain enough traction.

All that being said, I don't think it's logical to purchase an expensive .com before your company proves its success (or raises an absurd amount of money). Take your time, and get creative to find a workable .com, or get a domain that will still make sense if you ever want to purchase the .com. For example, served.io (no disrespect to them) could never change to servedio.com.

However, if your not in the consumer space, then I think alternative TLDs are a much more viable option. You're not depending on eyeballs for your startup's success. And if your target market is technology folk, it's even better.

10 Benefits of Rising Early, and How to Do It
After dealing with the nonsense from potential employers, recruiters, etc for a little while now I think I've become a bit more seasoned and can spot the BS quickly, this is an important skill to develop so that you don't waste precious time with dead-end leads.

If someone emails you regarding a job, immediately press for details (if there weren't many in the email). I occassionally get emails from idiot recruiters who think that secrecy is the best way to go and won't tell me which companies they are representing but want to get me on the phone 'just for a few minutes' to talk about these amazing opportunities. I usually give them one more chance and email them to explain that its important for me to research potential employers before spending time on any sort of application process and that I would need the company info to go any further. If they don't comply, I blacklist any further communication from them.

Basically, you need to know what a company is all about before wasting any time, once you have at least the name of the company, go to their website, read any reviews you can find from past employees, etc, 'google map' their offices to see if its a dump or if it looks like a viable place of employment. There's no shame in blacklisting communication from people who are wasting your time, I now make it a regular part of sorting through the emails I get regarding 'opportunities'
Would be awesome if someone built a WP Sopa plugin that did this for any WP blog, basically a splash page with how to contact your rep and what sopa could do to the net.

If anyone can build this let me know, we can help you host and get publicity and I'd be willing to pay you for your time if you think it's possible -> bwb@site5.com

It would need to be made soon so it can go to users asap to prep for jan 23rd,

I am actually fine with this requirement so long as it is not dictated to me what I use. It would actually be liberating to use my own equipment for some jobs over using a corporate desktop. Especially considering I favor UNIX based systems. I think most in the industry already own a personal laptop and smartphone. I think it is economical of a company to leverage that reality. With the reservation mentioned above, if I supply it then it is mine and I decide which environment that I use.
Instead of learning to admin a server, and then follow up with admin for the rest of your life, you can hand that duty over to experts. Should hundreds of thousands of people be engaged in doing essentially the same thing.

If you really thing appengine is shitty or overpriced, then it should be pretty easy for others to replicate and eat their lunch. The fact that no one else has managed to yet says a lot.

As an anecdote, reddit frequently has outages, they run on aws. If they switched to gae they wouldn't, it's as simple as that.

One wonders how it does rate limiting to avoid pointless resource consumption of faster, near links when the packets are going to be dumped by a slower, farther link.

In particular, if you intend to coexist fairly with TCPIP on an internet you might find your rate limiting code carries all the most of the work and timing issues of TCPIP anyway.

+1 for pointing out the contradictory research.....
I keep seeing talk about this, but it never seems to go beyond talk. It doesn't seem necessary to disable services entirely to get people's attention. Just adding a banner or link would have a huge impact. Consider the impact of adding a link to Google's front page or the Facebook top banner, or even a modified logo, with a link to a page which makes it easy to contact Congress (and which can handle the load).

Why does this require so much talk and so little action? Why do we keep seeing headlines of "consider", rather than the headlines we hope to see of the action taken and the resulting impact?
The interesting thing is not that people are risk averse (and thus choose 100% chance of $900), the interesting thing is that people become risk seeking when it comes to losses (and thus choose 90% chance of -$1000).

You're creating a bit of a straw man when it comes to behavioral economists and their view of "rational actors" - the whole field is built around the understanding that there is more to economic decisions than expected value.

Andrew Tanenbaum's Operating Systems Design and Implementation, in which he uses MINIX as the teaching OS, is also good.
There is also a lot of bias in this though. I have an interesting anecdote from this, one I'm not so proud of... For the first half of my writing 101 class I got a B-/C+ on every essay I wrote ~3-4. Then I took my girlfriends at the time "creative writing"/poem or whatever the assignment was and my teacher went bonkers about it thought it was better than sliced bread, tried to get me to take a creative writing class (which I milked and was like yaa i'll think about it). I wrote every paper after that and consistently got 95+ on them. Interestingly in the last paper one notable comment from her was "Your content is brilliant! your analysis of the book and your thoughts are the subject are amazing! however be careful with your sentence structure and grammer it detracts from the paper" I got a 97 on this and I put basically the same effort on this paper as I did in the beginning.

This is simple human bias if you expect something to be good it will be good, and has to do with how your teacher feels about you.
I don't understand. Kahneman's whole thing is showing that it's wrong to assume that humans are rational actors.
Your second paragraph is exactly the point - the choices are not equivalent to humans.
This question comes down to marketing, if the largest portion of your growth will come from search, social links, and web advertising then I think they are fine. They are really bad for national branding campaigns like radio and TV, where linking is not an option. It is interesting that Overstock is pushing hard for a re-brand to O.co. It's a great name, if they can pull it off and change consumer habits it will help other brands gain legitimacy in branding. As such though they have their work cut out for them.
If you implement optimizations, you can really significantly curb the cost.

I spent some time tuning SharedCount's API, which would have cost me $30-$50/day, and its now at about $1-$2/day.

- Move to Python 2.7 and enable multithreading

- Setup Cloudflare (this swallows about half of all my requests)

- Increase minimum latency and reduce the maximum number of idle instances. (I have 5-8s and 1-2 set, respectively)

- Setup the semi-undocumented Google edge cache (basically, just a Cache-Control: public, max-age=[seconds] header.

- Take advantage of memcache.

With this setup, I'm doing 3 million API calls per day at $2.

Type annotations are optional and for people who do use them, they provide at least 2 substantial benefits:

1. Better code documentation. Based on my experience with Python, reading someone else's code (or even my own code after a while) is harder than e.g. C or Java code because types do provide useful information. When reading Python function in isolation I often wander: is the argument to a function a list? a dictionary? a string? Knowing that makes a big difference when reading a code and when I don't know that it's hard to figure that out because you have to trace the whole control flow to that function. This is especially important in large projects where you can't keep all the code in your head and how to read small parts of it.

2. Tools can tell you about errors. Part of the Dart project are lint-like tools that check annotations and notify you about mistakes. If you e.g. annotate a function as taking integer but you pass string to it, a tool can tell you about such mistake. This is what statically typed compilers always do and, again, it's especially important on large projects where you're only responsible for part of the code. Dart doesn't force you to use type annotations but you can choose to use it in your project and get less bugs by using Dart code lint tool.

1. Reviewing everything submitted by users is unreasonable to expect.

2. People are upset that takedown notices are issued for works to which the issuer does not hold copyright and that those who issue such notices do so with impunity.
For those of you on the Mac that doesn't have strace but does have dtrace, here are some preinstalled dtrace scripts you have at your fingertips:

dtruss - similar to strace
opensnoop - all files
nettop - all network access
iosnoop/iotop - all io
execsnoop - all new processes
errinfo - all system calls resulting in errors

Not exactly the same info but I think much more powerful as it is system wide and you call always filter out what you don't need to know, or write your own scripts!

The solution is stop enforcing this dogma of requiring a specific book for subjects which clearly do not require the latest annual edition of a specific textbook. Teachers would instead recommend books they feel are good to use to pass their course. Without the exclusive book contracts, publishers couldn't easily and blatantly maintain a cartel on textbooks.

The basic economics of why school textbooks are so expensive is dead simple: The teachers and the schools grant publishers a cartel by forcing kids to purchase their specific new editions every year. Why anybody is suprised that prices are so high is beyond me.

There's a lot of truth to this. I'm doing everything I can to use my influence on the board of reddit, inc. to help, but the team we've got in place now has been carrying the torch brilliantly since we left.
I certainly agree that the translated JavaScript shouldn't need to enforce types in any way, unless Dart provides some kind of "downcasting" mechanism to give something a type it doesn't already have. However, that only applies if the Dart compiler doesn't statically enforce the types when compiling the code to JavaScript.

For one example: Haskell's strong static types all go away when you compile; the generated code does not do any type enforcement or verification.

The biggest thing I hoped the article would talk about got shot down in the very first section, which just said "Dart is dynamically typed" and explicitly dismissed any need to justify that, other than by saying "Users of dynamically typed languages ... will understand why we chose this".

I honestly can't even begin to understand why people consider dynamic typing a feature; when I saw the headline I hoped to see an interesting justification, but instead I saw it taken as a given and then used to justify many other things. I agree that almost all of those things do follow naturally from the assumption of dynamic typing, but I'd still like to know the rationale for that assumption.

The only justification I've ever seen for dynamic typing amounted to "because I like duck typing". However, a static type system can trivially enforce duck typing.
Serious question: who actually uses Yammer?

The only reason I know it even exists is because Coda works there. :)
Problems on a whiteboard don't test programming skills simply because the whiteboard isn't executable. You don't get the feedback that REPL gives you, so you can't build up your solution - and understanding of the problem - iteratively.

Seems to me that holding a code retreat and pairing with interviewee's would be more realistic. It would eliminate at least some of the pointless stress of interviewing and would get closer to a real programming environment.

It's not like nobody has enough computers so you have to use whiteboards.
Well why are you talking of mathematics and arithmetic, this is a programming interview not an interview to hire mathematicians.

Whats the advantage of Fountain Codes over more well known and deterministic forward error correction techniques like Reed-Soloman Codes?

The D.J.C.MacKay paper linked from the article lists applications in broadcast and data storage, but Reed-Soloman would work equally well in both those applications.

Hypothesis: With Reed-Soloman and friends, if you're unlucky and loose the /right/ n blocks, for small n, you can't recover your data. Is that n larger for LT? If I could maliciously corrupt your LT blocks, would I have to corrupt more with LT?

Hypothesis: If I randomly corrupt blocks with Reed-Soloman, does my likelihood of not being able to recover all my data drop faster than if I did so with LT?

Can someone say authoritatively?

I think, when the money you may gain or lose goes way over your possible wealth you will start to think really non-linear (non-rational).

but I agree that people with same wealth level will weight risk factor differently ( in each gain or loss). in other words simple utility function is not enough!
This is a great starter list. I used to advocate against remote teams until I by chance landed in one. Now I am sold on the reduced overhead and the ability to allow developers to work when they feel productive. The tools are in place, with source control, issue tracking and collaboration tools being provided as SaaS as well as Skype being such a great collaboration platform. With the cloud providing server capacity on demand there is really no reason for a new company to heavily invest in facilities and infrastructure.
I am not saying that reviewing everything is reasonable. I'm saying let's be glad the laws let you accept content without verifying ownership at all, and stop complaining that you have to take down content in dispute. The abusive takedown notices are a fraction of the number of legitimate infringements that take place. Content owners have to police the entire internet for their works. And we're supposed to have all this sympathy for the companies who have to respond to takedown notices by simply removing the content, not paying any penalty at all, when most of them are legit?
Indeed. Hiring programmers is about hiring people who bring business value to your organization, not about bringing in people who can solve Pascal's triangle faster than the other 90% of candidates. The entire first thread on this page is a shining example of what is broken with Google's hiring process.

37signals hires for business value because, as a small company, it has to. Google is a huge company and doesn't have the same incentives. Google's size can blind it to the fact that its hiring practices optimize for mathematical knowledge and intuition over business value. And, as a business, Google is wrong and 37signals is right.
You just need ILECs or CLECs willing to terminate SIP connections onto an SS7 switch; doing so is trivial for an organization that is getting into a Twilio-like business, but non-trivial for a typical web developer doing it just for a couple hundred of minutes or sms messages a month.

A Google recruiter pulled this on me over the past month and a half, where "sufficient" in step 4 was equivalent to both "3 times" and "until he says he's taking his offer and breaks off all contact". It was infuriating, especially coming from a company who is supposed to know what they're doing in terms of treating programmers.
...While on facebook, users willingly and explicitly define their interests, dislikes, personal information, etc.

Facebook doesn't need to 'extract' that information based on browsing information (although it probably could, given the number of sites that share information or use the fb api, and the links that users share with each other) and user posts (statuses, wall posts, notes).

Facebook has far more information available than reddit, so yes, it should be able to target ads much better.
