Well, them and voters.
US Naval academy, the entire 4000 person university lives in one gigantic dorm building. That's the largest dorm I can think of, at least in the USA. I've never seen it personally, but I've heard its spectacular and seen some interesting pictures of the luxurious common areas.

If you permit skywalks to make one large building, technically most of downtown Minneapolis and (I think?) Toronto would be one big building. If you define "a building" as you can walk from one place to another indoors.

I don't think interaction scales as well as some think, I lived in a 13 floor roughly 600 person dorm at university and as I think back I never set foot on perhaps a third of the floors, and spent the vast majority of my time on just two floors. So making it 100 floors tall would primarily mean I'd almost never visit about 90 of the floors rather than almost never visiting about 10 of them.

This also happens horizontally, not just vertically. I live in a 580 square mile county. I spend the vast majority of my time, probably over 99%, in about 4 of those 580 square miles. That's just kind of how life is, lots of sleeping, gathering and consuming food, working, raising/educating kids... I believe my county nears the size of the state of Rhode Island, however I don't think social interaction is much different merely because the lines on a map are closer together.

I have lived rural, suburban, and urban, and my limited observation is ignoring each other is a defense mechanism. So in rural areas we were all practically blood brothers simply by virtue of being neighbors, but in urban apartments I would not even know my neighbors names. Suburban is somewhere in between.
The business model of websites supported by advertising is roughly as follows: I send you a bunch of data, and I hope that you parse, interpret, execute, display that data in a particular way. Some of that will be useful to you (interesting stuff) and some of that will be useful to me (ad impressions).

Apparently, many people are not comfortable with that kind of exchange. However, people being people, they still want to see the interesting stuff. So what do they do, they install this (free!) ad blocker that gets rid of all the things that are not immediately useful to them. Unethical? Possibly. But not illegal, and not even widely frowned upon.

So at this point, as a businessperson, I must ask myself whether my business model is still viable. If not, I must change it. That's what it means to be an entrepreneur: find ways to turn labour into money. Under Western democracies, I have that right, subject to laws and regulations. What I do not have is the right to having my particular business model be forever profitable.

This is a concept that the music, movie and game industries refused to wrap their head around. Their model was (and largely still is) "I give you these plastic things with bits on them and you give me money". This was acceptable to consumers as long as the plastic was required in order to be able to distribute bits. When this ceased to be the case, the business model started to fail. Rather than move to a different model (which, I realise, I make sound much easier than it is), they held onto the failing one, introducing complicated and fail-prone systems to prevent people from separating the bits from the plastic, in the process alienating their customers by making it harder and hard to actually use their products.

So, no, I don't feel bad when your business fails because of ad blocking. Being a selfish jerk, I'm upset you no longer send me interesting stuff. Being a compassionate human being, I'm sad a bunch of people lose their source of income. But this is the free market. If your business fails, you did something wrong. Someone else will come along and do it right.

I am a female American. When I traveled through Seattle airport a while ago, I saw that every single person was getting selected to the mm wave scanner. I told the security guard I wanted to opt out...A few minutes later, a large male TSA agent came over for the sole purpose of yelling at me (it was loud!) that I opted out before I had been selected to go through the scan. This continued 5 minutes before my pat down. Thanks, America...
Like other people point out, yes it's better here than other places. I am grateful I don't live in Egypt. But, it upsets me to no end how quickly we throw away our constitutional rights or cease to care about corruption and ineffectiveness of mm wave scanners.

You don't have to verify the causality.

"media found out that africans and arabs were way, way over-represented in all [violent] crime categories" AND THEN "the Swedish crime prevention board (BRÅ) no longer publish crime statistics containing ethnic background information" is hilarious enough already.

I think you need to also drop the "simple" part as well.

This is a very non-trivial process so your casual response is a bit hard to swallow. And "domino effect" - I don't think there will be a vast tide of of people, but whatever.

So your answer here is great if you are a long-time tourist. Completely impractical in terms of career and work.

that aren't easy to give up
>Yeah, I understand completely ;-)...

No. I don't think you do. I don't think you have a clue. Your family history aside things are much complicated now.

For example, its hard enough finding a good school in my own neighborhood (US, english speaking) let along transferring my kids to a new school where they don't speak the language and I have to deal with bureaucracy and hope I'm not screwing up their future. Thats just one quick simple example. Tell a 5 year old she'll never see her friends again and good luck learning French, German, Spanish, or whatever.

I really can't believe you replied with "Yeah, I understand completely ;-)..." to that. Seriously.

On a final note. I'm Irish and lived (US) here 12 years. My family and I can move to Ireland at any time without worry for some of the larger barriers; visa and language.

However to do so is by no means: "extremely simple" or even just "simple".

This is HN, you just left a comment, and not expected to write a thesis on the subject.

That not your fault, people white-wash what are complicated situations all the time and over-simplify. However your off the cuff glib advice is not particular accurate or helpful.

You are probably right. Marissa Mayer wants to be known as a great CEO, which requires thinking long term. Loeb was mostly interested in short term profit.
They're much further in Australia:

If you are departing Melbourne on an international flight from Monday 10 December, you may be randomly selected for a body scan.

If you are selected to be screened by a body scanner and you refuse you will NOT be allowed to pass through the screening point for 24 hours. This will mean that you are unable to board your flight.

The big problem with Global Entry/TSA Precheck is that it requires you fly on a "participating" airline which are all the bumbling legacy behemoths and not any of the airlines (JetBlue, Virgin, Southwest) you might actually want to fly on.
That depends on what the rational person can afford. When they're thinking "500$ means I don't make my house or car payment this month and I'm not certain how I'll feed my family", they may say "I'll take the 1$ bag", consequences-be-damned. And they're still a "rational" person.
A couple of observations.

You probably shouldn't think that you can get your indie game done in a year, release, and ramp up revenue so fast that you'll soon be self-sustaining. Sounds obvious, but most guys starting out actually believe that there's a chance of it playing out like this. Starry-eyed optimism is probably a precondition for going anywhere near this business in the first place, but it must be tempered and kept in check at all times.

If you are building a game of substance (rather than a simple puzzler/platformer mobile app - which is a lottery ticket more than a business model), the game will likely take way longer to develop. As it should. Good games take time. This means that you should either be very well-funded, or have extremely low costs of living, or be working on the side of another income (in which case it will take even longer). This is not the way to instant riches, but since when did that ever work? Double down, dig your heels in, this will take years. But the end result is an awesome game.

Further to the point, you should probably not think in terms of the release that ends the project and where all your efforts either pay off or fall flat. Instead, the game should be put in front of users continually, gathering feedback, going back to the lab to improve it and repeating the cycle until momentum starts to pick up. That's when you know that you are near the final shape of the game. Don't even think about talking to the press before this. Luckily, if there is one community that is ready to try new things at any and all times it is gamers, so you shouldn't have much trouble getting this feedback. (Conversely, if even the ravenous internet hordes are indifferent to your project, you might need to tweak the formula).

While a long and hard road, a game developed this way actually stands a chance of success in the market, unlike the 'overnight success' stories that play well in the press.
Top 100 world ranked grand master here. The amount of time I have poured into this game is absolutely unreal, I could have probably raised a family of 5 in the time I spent playing StarCraft.

I found myself better at a lot of games after being so intense in SCII. Co-ordination, decision making, a better understanding of strategy, all improved. I got better at Chess, was able to pick things up quicker.

Great experience but I'm too burnt out to keep going in SC2. It got so hard you had to treat it like a job.

The thing about SCII competitive is, once you seriously get competitive, every single game you play is such an absolute mental drain. I used to have to do pushups / run a few KM before a few games. I had to mentally prepare myself for every single game.

Once you play at top competitive tier in SC2, every other game is honestly a joke (videogames, not boardgames). What other games REQUIRE you to have 300APM? None, that's how many.
If you sign up through Global Entry and not through the "you've flown enough that the airline likes you" version of the program, you are far more likely to get expedited screening.

You can also scan your boarding pass at home and discover whether you're getting expedited or not, so you know how early you have to be at the airport.
I see high rise residential buildings as nothing more than modern day slums and ghettos.

Some people prefer to live in cities, for example people who are driven to earn lots of money, people seeking higher education or cultural experience, people looking for partners, etc. For those people, depending upon the density of the urban environment and their will to dedicate significant portions of their waking hours to a soulless commute, sometimes that means there's no other option but these buildings.

That said, I basically share your perspective. After living in apartments throughout Asia and London for a decade, I really enjoyed being in a house again in Los Angeles and am currently considering building one somewhere in remote New Zealand. My thinking is that high density cities are lovely to visit, but quality of life for the nine-to-five cityslicker typically sux. The 'burbs aint that much better, given commute overheads, an often broadly similar lack of nature and, per capita, not entirely dissimilar rents (despite the extra space afforded).

One point nobody seems to have made is that capital for buying houses is virtually free in Hong Kong .. something like 1-3% interest IIRC.
Exactly this. All markets are more or less "free" and the question is how to structure markets to deliver the greatest benefit.

Absolutists about free markets are at least being purposefully obtuse if they don't admit that they think vendors should win every advantage from irrationality, inelasticity, and information asymmetry, plus every transitory advantage as markets get dominated for a supposedly temporary interval and for supposedly salutary purposes.

The above, combined with a bias toward investor-owned enterprises over co-ops, customer-owned, and nonprofit enterprises is what brought us to a place where market liberalization only hardens the position of incumbents.

I use QC-15 Bose headphones daily. You have to be listening to music (or your favorite white/pink/etc noise) while wearing them to be effective blocking voices nearby, don't believe anyone that tells you otherwise.

The paradoxical effect is that since they are effective blocking low frequency noises, the voices kind of stand up if not listening to anything.

Russian here. We won't see a similar map of Moscow for two reasons:

1) Immigrants can't afford any housing.

2) Most rent is private and not reported anywhere; most immigrants are illegal and not accounted anywhere.

Moscow won't segregate because people are awfully un-mobile.

If this changes, we may share the fate of cities in USA/Europe.

The problem is that a lot of immigrants are flowing in (from central asia) and there is no political will to limit their influx / control their quality.

Right now all the immigrants work and only resort to crime in dire situations, but I'm afraid this is bound to change if measures are not taken.

Rampant xenowhat?

Yes. It's very different to what you get, for example, in Australia. Or most parts of Europe. Yes, you'll probably be a gaijin forever, even if you get naturalized (and renounce to your other nationality). But there's a huge difference between what the japanese are, and have always been, and xenophobia. Of course you get a different treatment unless you show them what you know and your respect, but it boils down to the kind of society it is and the fact that you're, at first sight, different from them. But different, not worse.
In this case, it means that lots of memory accesses are required in mostly random order. This makes parallelizing on GPU hardware much more difficult than something like an MD5 or SHA hash, which don't require much memory access during the computation.

This also boosts the cost of making dedicated cracking hardware (ASIC or FPGA type hardware)

I'm having a hard time finding actual memory usage of a single password verification though.

After a bit more reading just now, it looks like you can also adjust the memory-work-factor of scrypt as well, which doesn't appear to be available for bcrypt (very unsure on this one though, please dont' take my word on it).

Does anybody out there have a good side-by-side comparison of practicalities like "memory usage", "flexibility", "can it be parallelized on CPU/GPU/FPGA/ASIC" and so on across all the popular hashing setups?

Just curious -- what's the usage profile for Office in the HN world? Where I work, we use Outlook (on macs), excel on occasion, powerpoint, and that's about it. Around 10 years ago or so, we'd draw up big honkin' requirements documents in Word and e-mail them around, but now we use Wikis & Stories (jira/VersionOne/etc...) for that, so use of Word has plummeted to about zero.

Excel is used a fair bit for columnar data and the like, and frankly, I think it's not a bad product at all, though for personal use, I'd probably go with a google docs spreadsheet. And for simple cases, the google docs presentation software is an adequate powerpoint replacement.

My general question/theory is that a lot of free/cheap/niche products have been nibbling at the edges of Office, and I'm wondering if/when a tipping point will occur, at which point it'll become totally irrelevant. On the other hand, perhaps if there's enough pushback against cloud services due to the NSA thing then standalone desktop apps will make a resurgence. "Office is Dead. Long live Office?"
The code here is well executed and I think you have a smart idea to tap into the Twitter visual stream...but to paraphrase a famous researcher (or engineer, I forgot which), the world has an abundance of information but a lack of attention (and this was said decades ago).

There's not really a benefit to seeing a realtime stream of Twitter photos. In fact, if you were to show me photos that were timedelayed by minutes, hours, or even days, how would I even know the difference? Realtime is effective to get a grasp of what's going on now, but there's no way to discern that from a raw real-time feed. As an example, you don't get the "pulse" of Twitter by reading the firehose, but through the trending hashtags/terms, which are pre-processed and clustered.

In other words, I think there's a lot you could do by clustering/filtering around several kinds of facets. For example, show just pics from accounts with more than x number of followers as a proxy for "quality". That'd be a start and a relatively easy one to implement.

That wouldn't be the case in many scenarios I can think of:

1. DB backup is compromised (from an offsite backup storage, think S3).

2. Developer laptop lost, with a copy of the database locally. (source code may be available, but the site-specific key probably wouldn't be. As that's a config var on the server).

3. SQLi that dumps hashes to the page.

I'm a big fan of making the job harder for attackers. There are lots of attack vectors where a 'pepper' value would be useless. But not all of them. And it's nearly free to implement. Might as well.
