It brings up an interesting point, though. If I have an infinite number of rooms and an infinite number of guests, then one might intuit that every room is occupied.

There is a mapping of every guest to a room: guest n is in room n. Yet somehow there exists a room that has no guest, despite being able to model both rooms and guests with the same infinite set.
"YouTube is free to remove content, and others are free to ask YouTube to do so. To say otherwise is to limit their freedom."

YouTube is free to listen to anyone, but the executive branch of the government should not be the one asking. If it is illegal or top secret content, then fine and dandy, there are rules for that. Otherwise, it is an attempt to intimidate YouTube and squelch their 1st amendment rights.

Official in town who's managing the project shows up, "What the hell are you doing! You can't lay concrete while it's freezing."

Wait, what? Town official witnesses substandard work and just let's it go on? How was that not grounds for at least withholding payment from the contractor?

we settle for $500k in damages, not enough money to fix the defects.

Shitty contractors to be sure, but in a properly-executed contract agreement, there should have been ways to mitigate the poor performance.

Erlang is nice, but has its own not-so-simple issues: http://www.youtube.com/watch?v=G0eBDWigORY

Interestingly, many things in Go's design that might seem 'deficiencies' from the point of view of Erlang means most of those problems don't apply to Go at all.
It's hard. Usually it's well-intentioned taxpayer protection legislation, passed after some disaster contract like the big dig, which actually reduces the ability to objectively evaluate the realistic and competent bids.

Minor example: Town AV girl needed a new video camera. She knows what she's doing, researched, found the best model as far as pricepoint/features and a good place to buy it. We had to convene 2 subcommittee meetings and make her go way out of her way to find that model offered 2 other places so we had 3 bids, and document them, before just doing what she wanted to do anyways. Probably wasted an additional 10 hours of salary on the taxpayer dime. This is all by statute, it wasn't us being a bunch of bureaucratic morons.

There is no such thing as a typical company and this a data center not an office park to my knowledge. Having said that a typical small office maybe 100 kW or so. Most medium sized office buildings we would be familiar with I would say are 500 kW or less. I would peg Walmart/Carrefour/Tesco/IKEA type store to be 200-400 kW or so at peak power. Typical house would average 1-2 kW. Interesting links from US Gov: http://www.eia.gov/tools/faqs/

Apple is doing this site because its greener than coal and I doubt they want to run diesel or a turbine. Greenpeace and other environmental companies have been giving Apple grief and the solar farm is part of their response to that. Apparently they also have 5 MW of fuel cells in the farm (where FC is more efficient than coal power plants and by extension fewer co2 emissions for same power). Turbines can easily provide that power and can get up to 60% efficiency in converting natural gas to electricity in ideal circumstances but are also pretty big and loud and may require an actual operations team to run and might be hard to get one that small. Diesel can be more compact but tend to be very inefficient in converting fuel to electricity and you still have to ensure its getting fuel.
Quoth the article:

Tunneling in any dense urban environment is an expensive proposition, but the $5 billion price tag for just the first two miles of the Second Avenue subway cannot be explained by engineering difficulties. The segment runs mainly beneath a single broad avenue, unimpeded by rivers, super-tall skyscraper foundations or other subway lines.
But I don't think the two envelope paradox has anything to do with that practical impossibility. It is about the rules of symbol manipulation and modeling.

Exactly this. The two envelopes paradox is a paradox only because using a fallacious argument leads to the wrong result, and the Wiki page proposes numerous resolutions to the problem as well. I like this way of stating it (from http://en.wikipedia.org/wiki/Two_envelopes_problem#Non-proba...):

1. Let the amount in the envelope chosen by the player be A. By swapping, the player may gain A or lose A/2. So the potential gain is strictly greater than the potential loss.

2. Let the amounts in the envelopes be X and 2X. Now by swapping, the player may gain X or lose X. So the potential gain is equal to the potential loss.

In the first case, A and A/2 are actually referring to the same amount of money. You have to condition on what A is: If A is the larger value, the second envelope cannot contain 2A; A/2 is equal to the smaller amount. If A is the smaller amount, then the second envelope cannot contain A/2; A is equal to the smaller amount. So your potential gain and loss are both equal to the smaller amount of money, and you have no logical reason to swap.

I've never worked with a top-notch young engineer. Brilliant, yes, top notch, no. Every single one has had misguided priorities, significant experience gaps (leading to both bad engineering decisions and misguided priorities), and -- even in the best of them -- hubris.

Despite their intelligence they've always required constant senior level supervision, and have generally been the ones most likely to create maintenance-heavy components due to inexperience.

I'm not sure why our experiences differ so substantially, but I'm happy to hire only senior engineers and let other companies pay to train the young ones. The senior engineers are more than worth the minimal financial premium.
> I'm really struggling to square up my understanding of how the former problem works with my intuition that if every room is in an occupied state, you can't magic up some in an unoccupied state.

That's the problem with infinites. Consider the number of all positive integers. Let's call it a1.

Now consider the number of all even positive integers. Let's call it a2.

Each even integer can be directly mapped to an integer and the other way around by multiplying or dividing by 2, right? All integers can be multiplied by 2, and all even integers can be divided by 2.

So a1 = a2, the number of integers is the same as the number of even integers, even though you'd intuit the number of integers to be twice the number of even integers.

Just as it does when reaching the infinitely small (0.999… is precisely equal to 1), intuition breaks down when reaching into the infinitely big.
How about generating an infinite sequence of bits to generate any positive integer (in binary) with uniform probability? Sure it will take infinite time, but so may the method in your note. As another comment here points out, it would take infinite time to write down a purely random number anyways.
Ask HN: Hacker houses...
I think it would be great to create a house full of like minded startup enthusiasts - developers, designers, biz devs etc. These "hacker houses" could be particularly prominent around startup focal points: Palo Alto, San Francisco, London, Berlin.

How many people would be willing to move in to a house of other hackers/startup people?

Do you think initiating such a creative environment would spawn new interesting ideas and projects?
I am thoroughly confused as to what your point is. What is the problem with Swizec's wording in your view? Should s/he have written "Can you make room for more guests?". I agree that you could argue that right now there is no room free, and that the answer should be No because of that. However, given that you can easily make one room free by having every guest go to the next room, that just seems overly nit-picky to me, and like you are intentionally trying to miss the point.

There are many very entertaining discussions of "Hilbert's Hotel" online. I look them up once or twice a year for teaching my math classes. To answer your very pertinent question, I suggest looking at

http://opinionator.blogs.nytimes.com/2010/05/09/the-hilbert-...

for an illustrated, and I think illuminating, discussion of what to do if countably infinite buses, each with countably infinite passengers, drive up to Hilbert's Hotel with infinite rooms, each of which is already full.

No retainage?

You don't bring in your generalist town counsel on retainer to handle a million dollar construction lawsuit. Would've been nice to get all that work for free, mind you, but he's not in the construction lawsuit business and didn't have 1.5 million of free time that year, or any expert witnesses laying around.

Town official witnesses substandard work and just let's it go on? How was that not grounds for at least withholding payment from the contractor?

Withholding payment means a more expensive lawsuit than the sidewalk was worth. We wound up just dealing with the shitty cracked sidewalk. Don't get me wrong, he reamed them out on the site, but they basically told him to get lost and when we explored our options, turns out we had to just take it.

Pingdom reported several minutes of downtime for my domain which is hosted through cf. seems back up again though.
Their site was down for a while as well. It's back up now, but the routing is still down. Quick tip: Go to control panel, select the gear drop-down by your website and select 'pause cloudflare' until things resolve.
You don't have to do that. Just use following simple steps (assuming that the hotel rooms are all along one infinitely long corridor):

1. Have all guests of the hotel simultaneously pack their things and move out of their room onto the hallway.

2. Have all guests simultaneously move along the hallway to be standing in front of the room next door (in the same direction, obviously).

3. Have all guests simultaneously move into the room they are now standing in front of.

The first room is now empty, with nobody having had to leave the hotel, and every guest still has his/her own room.
> I find it absolutely ludicrous, that people want to enforce their own value judgment on media, and what they are allowed to report on and on what not.

I find it hilarious that you consider what the Sun does to be reporting. Like those hard-hitting journalists at the Weekly World News. How dare I tarnish their sparkling reputation with my disparaging of their highly regarded journalism style.

> Are you seriously arguing that a paper that 10% of Britain reads every day should be banned from advertising on Twitter, just because you disagree on their reporting style?

No, I'm arguing they're an indefensible tabloid rag so aligning yourself with them is risky. Nobody is discussing "banning" except you. I would prefer Twitter doesn't accept their advertising dollars and if I see a Sun ad in any of my clients I'm quitting too.

The number of people who read their idiotic rag is neither here nor there. If you're seriously suggesting that at the very least 10% of any group isn't comprised of borderline retards, then you're delusional.

Using my eyeballs and wallet to vote isn't "banning", it's exactly what I'm supposed to do. Vocalize my concerns, try to get a response, and if they're not receptive, take my business elsewhere.
Most NYC tech startups will be more than happy to visit with you for a bit and give you a tour. I did this just before graduating from University. I visited General Assembly, Betaworks, Etsy, and also some really small companies. Just email beforehand and try to arrange a time that works for both of you.
Are they actually committing themselves to the incumbent role, or do they recognize an industry in decline and then suck whatever profits they can out of the businesses before flipping them? Layoffs, pension raiding, fat trimming, etc.

It's fairly easy, in theory, to take a bloated and inefficient company, cut it to the bone to reduce overhead, then position it as more profitable for resale. On paper, sure, it's more profitable. In reality, it's just a similarly bad company that's been trimmed up and given a new paint job. It's very similar to the real estate playbook: buy a delapidated property, touch up the exterior, then flip it as if it's shiny and new. (The beauty of PE, over real estate, is that PE firms can rig the game to benefit one way or the other, due to debt structuring. If they can flip the company for a profit, they win; if the company goes bust, they're insulated from the damage.)

I would say that an overpresence of PE in an industry is a decent indicator that the industry is in trouble (or is ripe for disruption). But I think PE guys realize that, as well. They're just in it to make the quick, easy buck, rather than take on the burden of reshaping the industry. I wouldn't call them "risk averse" so much as I'd call them opportunistic. It's just a different kind of opportunity, and arguably a less socially valuable one.
Right, so the occupants of n+1 would have to move to n+2, the occupants of n+2 would have to move to n+3, and so on. Somewhere, the occupants of n+infinity-1 and n+infinity would have to share a room, but I guess everyone accepts this issue because you'd never actually reach rooms n+infinity-1 and n+infinity by counting/visiting.

I'm no mathematician, but this seems to be an edge phenomenon that everyone is willing to ignore. I suppose you could just as easily tell the new guests to run down the hallway until they find an empty room at the end; out of sight, out of mind...
> Everyone cheats.

Well, yes, if you lump all the things you named together and call them all "cheating" without differentiating between them, yes, everyone "cheats". But I don't think everyone would agree that all the things you named should be lumped together. That's a subjective judgment, which means we probably won't get anywhere arguing about it--but see further comment below.

> Successful people get used to knocking down the hurdles others endlessly throw at them, often unfairly.

But the way you are putting it, anything I don't like or anything I don't want to comply with is just a "hurdle" that I'm justified in knocking down. By your logic, if I want my boss's job, it would be OK for me to murder him and then fill the vacant position; after all, he's just a "hurdle", right? Or if you don't think that would be OK, where do you draw the line? What principle lets me differentiate between things that are just "hurdles" that I'm allowed to knock down to be successful, and things that I'm not?
Cloudflare not serving content that is routed through them is down for all intents and purposes, regardless of where the fault actually lies.
Welcome to 2035...the Age of Surprise (US Air force video)
So what's the solution? A return to an 1800s-sized government complemented with privatized solutions for everything else to make up the difference? I'm being serious - that's not something I would necessarily mind.

Unions do suck, but even more so in the government sector where they hold the taxpayer hostage and its the government that gives in to their every demand (since they always take the easy way out) with almost no alternative for recourse, vs in the private sector where alternatives can and do pop-up and are routinely considered.

The difficulty would just be in smoothly scaling back from this 21st century behemoth of a government that has gotten just so goddamn big, bigger than anyone ever imagined a hundred years ago regardless if it was the pro-State or pro-Federal government people you were referring to.
It was totally and completely down for about a span of 10 minutes then they fixed their site, but external routing is still very very spotty.
The difference is an infinite number of rooms can accommodate an infinite number of guests and still have room for one more. An infinite number of full rooms can accomodate no more guests. They're all full by definition.

That is, unless I am also thoroughly confused.
I'm not sure how this was intimidation? It was a request, and YouTube declined it. That proves that YouTube's is free to act as it chooses. (YouTube could also have decided to remove it, regardless of the request to remove it, and that would be within YouTube's rights as well - and not contrary to the video poster's rights.)
The key word there is systematic. A mob is not methodical in its plans nor has any regularity, therefore, it does not systematically use anything.
Walmart is just about the most anti-union company in existence. Bad example.
There is no empty room initially. However, by having all guests move simultaneously, you can make one room free without having any guest leave the hotel.

Incidentally, this is one way to define infinite sets. A set is infinite if and only if there exists a proper subset that has the same size (cardinality).

The numbers don't make sense to me. The NYC subway costs $2.25. Is this figure weighted to account for reduced fare users?

Similarly, the Muni in San Francisco is $2. BART is commuter rail, despite its name, so I don't think its fares should be counted as "subway" even though some of it is underground.

Finally, Tokyo has a zoned system, ranging from 130 yen for short JR trips to more than 1000 yen for Tokyo<->Chiba trips.

And none of this includes monthly passes, 10 ride discounts, or the MTA's 7% "bonus".

If a computer cannot have infinite memory, then it cannot go beyond discrete finite automata (DFA) itself. Undecidable problems are several steps more complex than what a DFA can solve. In other words, the theoretical capability of a computer with finite memory is way less than a computer that can solve all but undecidable problems.
Your explanation of why a powerset of a countable set is not countable didn't make intuitive sense to me, but wikipedia concurs ( http://en.wikipedia.org/wiki/Cantor%27s_Theorem ): ...the power set of a countably infinite set is uncountably infinite...

You've made an excellent and entirely counter-intuitive observation, sir.
7 Billion for 29 stations and a full line? I wish.

http://www.theage.com.au/victoria/south-morang-finally-gets-...
1/2 a billion for extending the line 3km and building 1 station. (All in the suburbs - where there used to be a train line that was ripped up)
Compare to the new Seoul Bundang line which is 32.8km with 28 stations in some of the most dense urban areas on the planet. It'll run a bit under $400 million to build or about 1/17th the cost.

Where are you getting that cost from?
If you hone your design skills enough, and you get to know WordPress development, you could create premium themes and then sell them on Themeforest.net. Some of their top sellers are making $10K+ per month.

I agree with you there. The vast majority of "philosophical" questions of type "Does X exist?" are really quite trivial once you clearly define what you mean by "exist".

As in your example, the number two doesn't exist in the physical universe. There is no physical object that we can point to and say "This is the number two". It has some physical representations (such as some sequences of electronically encoded bytes in this very comment), sure, but that's not quite the same thing. On the other hand, the number two obviously exists in a mathematical sense. So it really boils down to being precise about what you mean by "existence".

It's almost the same with infinities. I say almost, because there is some uncertainty when it comes to physics, e.g. whether the physical universe has discrete or continuous coordinates (and the article mentions singularities, which is a similar problem).
How can they push back against unions? They are mobs. They have been mobs since day one. In fact, in the early days union leadership was down-right criminal (not saying that's the case today). Look at what is going on in Chicago right now with the teachers union. They don't give a shit about our kids. They want more and more and more until the goose is dead. They are not willing to toss out bad teachers and work under the same rules that proper the free market.

As an engineer I have to be good at my job. If I suck at it I either get fired, or, as a business owner, loose my ass. This simple reality does not exist in the unionized ecosystem. You can completely suck at your job and have a job for life. Not only that, you can retire and continue to earn a pension for life. Does that represent the values of our country? Is that what we think this nation is about? The land of the most incompetent and lazy? I think not. Take unions out of the equation and see how the incompetent go away or, all of a sudden, decide to actually work 'cause they'd have something to loose. Unions do nothing good for our country today. Don't buy union products if you can help it.
