I currently live in Manhattan, and work for a start up in Manhattan, and I can assure you that it is very possible to live in NYC on a "typical" start up salary.

While I don't know what the true "typical" start up salary in NYC, I'll give you my experience: I interviewed with 7 start ups, and 6 of the 7 were offering a nice chunk of equity and salaries over $100,000. If you can't live in NYC on 100k, you're doing something very wrong.

And, great article!
Great post, Dan. It reminds me of the article the Buffer App guy wrote on his experience getting everything up and running. very smart and disciplined to root out the demand before committing dev. keep up the good work
Nope.

Fusion reactors are fundamentally different from fission reactors. You have to get a tenuous wisp of hydrogen (the reactor in this particular experiment was running at 10 mTorr, or 0.0013% atmospheric pressure) very, very hot, and keep it away from solid matter, which is millions of degrees of colder than the fuel plasma, and will suck all of the energy out of the reaction.

You shut off the containment coils, and tremendously hot plasma ions leap away from each other, instantly stopping the reaction. If the reaction somehow "runs away", which it absolutely can't, then it brushes the walls of the vacuum chamber, poisoning it with cold metal ions, like injecting lead shavings that have been chilled to absolute zero directly into your heart.

If our magical "runaway reaction" somehow overcomes this, and melts a hole in the vacuum chamber, then the atmosphere rushes in, both freezing cold and at intolerably high pressure, like the North Sea flooding into the hull of a submarine resting on the ocean floor.

Fusion reactors don't melt down, or explode. At all. It just can't happen, much like how a Yugo rear-ending a garbage truck in Brooklyn doesn't instantly consume all of New York City in a gasoline fireball.

It is indicative of the great difficulty of both starting and sustaining a fusion reaction that the only fusion reactions which produced more energy than they consumed, that have ever taken place on Earth were powered by atomic bombs, and still only ran for fractions of a second.
But wait, we were talking about buildings, not cities. A city is made up of many buildings. And buildings are torn down across cities on a daily basis.
You're wrapping Turk in a human. That provides value. +

Have you ever dealt with Turkers? I did for a client once. Here's the task, simplified: "I give you job title, you give me degree title. For example, if I say 'elementary school teacher' you say she has a Bachelors degree in Education and so your answer is Education."

Input (to turker): Car technician
Output (from turker): BACHELORS DEGREE IN CAR TECHNICIAN

I rejected that: sorry, I will not pay you two cents for that work. The Turker got into a running email argument with me: "WHY U NO PAY?" "Because the answer is in all capital letters, does not follow formatting instructions, and is wrong." "U NO SAY WRITE SMALL LETTERS!!"

Regardless, though: reselling labor is not skeezy.

Hah, don't mind my snarky comment. Just get these kids off my lawn.
If it's worth my time, no.

If it's spam, yes.
I love Brooklyn, but the rents aren't _that_ different from Manhattan if you're in the "hot" areas. Maybe 30% cheaper, but not 70%. Yeah, there are 'low' rents if you're willing to live an hour outside the city, but if you're in Williamsburg or Park Slope, it's not really appreciably cheaper.

And at least for software engineers, you probably _do_ make more in SF than NY, since it's a much more competitive job market for hiring a good software engineer. Just look at the wars that have been going on between FB and Google over hiring top talent. There's still nothing like that in NY.
The counter-argument is, of course, that someone who knows they can't fulfill all contractual clauses will try to check off the easy ones only - including the risible demand that M&Ms be sorted. The argument in the article is simply invalid, because it can be used to justify everything - the more unreasonable, the better!

Instead of such a ridiculous demand, they could have just picked a couple of random, but useful clauses from the contract (like the number of sockets) and checked those instead. Yes, it would have taken a couple of extra minutes, but certainly a huge concert is worth that.
There was no actual fusion reaction occurring in this test. He just confined electrons in an air plasma. No hydrogen was injected.

And, of course, it didn't take place in an apartment.
I think this can be boiled down to "have self confidence, don't flake, be nice". Reputations are built over a lifetime.
It's not uncommon, but there are also lots of potential employees that have wives and kids (70% or more, I'd guess)... they're basically locked out unless they either want to do a long commute, or live in a tiny place.

I've done a lot of hiring to companies both in NY and in other cities, and the "where will my kids play and where will they go to school" is a standard issue for anyone you're hiring over 30. The answer in New York is generally "somewhere a lot less nice than they would if you lived elsewhere."

There's little denying that NY rents / housing prices are way out of line with average income at this point. I've heard bankers making $500K complain that they have to move to upstate to get a decent sized house.

I think this is still a library problem, not a language problem. "Compiling" a string at runtime for `sprintf` isn't any more difficult than doing it at compile-time, and plenty of regex libraries do very similar things.

Compiling of printf strings isn't done, though, because nobody cares about string performance unless they're writing UNIX command-line utils. If you're writing C you're probably only dealing with strings for (infrequent) IO, spending the vast majority of your time crunching away on pointers and integer types (floats in niche cases). In the end, you're probably only printing something out because someone needs to read it, and how fast can humans read, anyway?

This goes just as much for the printing of floating point numbers. (http://www.serpentine.com/blog/2011/06/29/here-be-dragons-ad...)

In fact, I'm assuming and hoping for the sake of his neighbours that
he's not actually attempting fusion. If I recall correctly, doing
actual fusion with one of these requires deuterium and tritium and
produces a crapload of neutrons for which I really doubt he has
adequate shielding.

Yes and no.

The very lowest-energy-threshold fusion reaction is deuterium-tritium, so must research tokamak reactors use that. The JET[1], ITER[2], et al.

But tritium is both expensive and excitingly dangerous, (It's an alpha emitter, which is ordinarily harmless, since the alpha particles aren't energetic enough to penetrate skin; but it's a radioactive gas, not a solid, so you can inhale it and get all sorts of amusing cancers) so real amateurs prefer Deuterium-Deuterium fusion, and the kind of fusion reactor that that produce the higher energies needed to accomplish it, known as fusors[3].

D-D fusion does produce neutrons, you are correct. But the PF reactor is a pulsed device, with a tiny coil size: it doesn't make many neutrons, and it produces them for seconds at a time. This guy has been checked out by the NYFD, and they've signed off on the project. If it was a power reactor, neutron emission would be a problem, but it's not, so it ain't.

I fucking cried.

He was like, "I hoisted out some stuff that should have been behind interfaces." ... I didn't need an interface because I only had ONE and specifically made the API have a low surface area so this could occur IF IT NEEDED TO.

If you think that it's good content, that people on HN would enjoy, then you should submit it - I would rather that my upvote goes to the person who actually wrote the content. If you get upvoted, then you were right and should trust your judgement. If not, then either you should reconsider your judgement, or you submitted it at a time when there aren't many people on the site.

However, if you find yourself submitting everything you write - or that most of your submissions are being killed, or flamed - you might want to reconsider your judgement (or all of the stuff you're writing is enjoyed by the community, which should be very obvious if it turns out to be the case).
Not necessarily but discretion is advised. Some prolific users submit their own posts (ex: http://news.ycombinator.org/item?id=2837905).

The word parts (affixes) in this test appear in more than one word in the most frequent 10,000 words in the British National Corpus.

Researchers believe that in order to use word part (affix) knowledge when guessing the meaning of unknown words, you need to at least: a) recognise a word part in the word, b) know the meaning of the word part, and c) know its function (i.e., part of speech)

This test measures each aspect of word part knowledge: whether you can recognise the forms, your knowledge of their meanings, and your knowledge of their functions.
Not at all if you feel someone in the community would find something of value in your content. Comments are essentially one's own content and there are tons of those around.
Of course not! That's the whole point of the upvote system. If your content is good, it'll float. If it's spammy, it'll sink.

Now hold on a second. A lot of people in this thread are saying things like "well if you didn't want it on the internet, you shouldn't have put it there!"

A lot of this isn't people that intentionally published things, and have now changed their mind, or want it to be removed from the stormcloud.

A lot of this is people who mistakenly posted things to their feed, then deleted it after realizing their mistake.

Take this example: http://www.reddit.com/r/somethingimade/comments/j6c7y/i_made...

Really like this counterpoint after all the LISP elitists so often snub other langs. The Ruby version is much more elegant and readable, in this little example. Would love to see more comparisons, specifically hacking around the lack of macros in other langs.
Here's an example:

http://www.vt.edu/about/buildings/surge_space_building.html

"The building provides space to temporarily house academic or administrative units that are displaced because of renovations to their home buildings. The facility was designed using a pre-engineered steel frame with its exterior clad in metal panels and precast concrete-like panel accents. The building is designed to be disassembled and recycled in 10 or 15 years.

One floor; 45,000 square feet. Find a public access defibrillator in the hall intersect."
Working out the licensing for this is quite the challenge.

It uses a duel licensing (AGPLv3 / Commercial) setup. How AGPLv3 applies to web applications is a significant grey area, and could imply an expectation that all javascript code of the application needs be AGPL also.

Answers in the forum are vague and no clear indication has been given to when a commercial license is is not required.

TL;DR: Want to use this in a web app? Pay for a commercial license or consult a lawyer

This is pretty cool. Turns out it runs the .NET microframework which is a Microsoft project to bring .NET to embedded devices. It brings embedded devices closer to a lot of people which seems good for everyone. I was skeptical about it being a real "open source platform" as they say but it really is. Not 100% open but boy is it good for MS. I wonder if they've opened up any more since then.

I agree. I really liked the thought process and the history/experience that made you think of using MTurk for this project. It shows that we sometime stumble on ideas that aren't just useful for just ourselves.
Yea, I agree. My main point was that you can't get blood from a turnip. I don't think DRM will change sales (or even affect them that much). Those who can afford will continue to play what they normally play, and those who can't afford will just opt out of playing PC games that they can't pirate.

I perhaps misread your original statement as saying "people won't pay, so they get DRM." I don't really think this is the case. I think this kind of DRM is inevitable as a natural loss prevention measure(whether the threat to profits is imagined or real), and I think games that don't provide enough content to mitigate the hassle of DRM (real or imagined) will suffer regardless.

D3 sales will be huge, and SC2 sales were too. I'd hate to see someone draw the conclusion that it's the DRM selling these products.

edit: In light of your response I see now exactly what you meant in your original post.

Consider https://gist.github.com/1119534, which demonstrates a pattern-matching syntax that (at compile-time!) constructs a minimal traversal of the data structure to find a match. The only way to do this in a language without macros is to write your own compiler.

Hm, It can be a real problem if you have the joy of working with old C++ code: the initial codebase might have had its own string type, and then some more classes added by long-gone programmers who thought the earlier types were slow, and then newer code added by people who actually use std::string (well, you get the idea).

(much to my regret, that is a true story.)
