Agreed. I'm a masters of architecture candidate working in this area[1] and I would add that to engage in contemporary urban theory would require a much more sophisticated urban simulator than is achievable with the current state-of-the-art. Contemporary urban theory goes beyond issues like outdoor comfort and appropriate formal scale (which is what this blog post seems concerned about) to additional issues like hyper and mega-city growth and resource conservation. Taking this into account requires multiple simulations that would be able to model the inherent trade-offs of urban design.

Traditionally there has been software like Esri's CityEngine - http://www.esri.com/software/cityengine - which procedurally generates[2] urban geometries based on user-defined typologies and land-use. However CityEngine is just a geometry generator, and therefore far too basic to be used for contemporary design which must also negotiate factors like building daylight accessibility or positioning transit nodes for optimum walkability.

A decent urban simulator therefore needs not only a procedural city geometry generator, but also simulators for walkability, building operational energy use and environmental simulators (ventilation, solar radiation etc). MIT's Sustainable Design Lab is developing the first (I believe) serious integrated urban modelling platform: Urban Modelling Interface (UMI) - http://urbanmodellinginterface.ning.com/. Unfortunately UMI doesn't at this point include a way to procedurally generate urban geometries.

A combination of CityEngine (with a much friendlier UI) and UMI would provide the kind of complex simulation environment that I think a realistic urban simulation game would require.

There is a lot of research into the computational modelling of urban dynamics. A good place to start would be Michael Batty's seminal book on the subject: http://mitpress.mit.edu/books/cities-and-complexity
Quality of practice is also important, and probably a major factor in your example. My knowledge and skill will be vastly different if I spend 500 hours playing against the best players in the world, compared to spending 500 hours playing in Bronze league (does Dota2 have a bronze league?).

I've run across a couple HAMT implementations you might not have seen:

https://github.com/mattbierner/hamt/
https://github.com/Tvaroh/moreartyjs

The first implementation (hamt) is interesting because it's in a same semantics compile-to-js language (by the author) called Khepri and it benchmarks pretty well on datastructure microbenchmarks.

http://khepri-lang.com/
https://github.com/mattbierner/js-hashtrie-benchmark

The second is a less interesting pure JS implementation that I show as faster than mori and slower than hamt on the hashtrie-benchmark. I've been meaning to test them on a wider variety of benchmarks (more aggregate operations and vs transients) but I only ran across them last week and I've been busy.
No, the bits I got to before catching up with the image loading were quite pleasant. It works because the images are actually illustrating and adding content; unlike e.g. the pictures embedded in most news stories, which are really a whole separate piece of content that forces you to jump out of the flow of the story if you want to consume them, these are part of the flow of reading the post.

Except when they fail to load, unfortunately. Content this size should really be hosted on S3 or equivalent, but the author probably didn't expect this scale of traffic.

Such as?

Without properly weighing the risk of a lawsuit, there's no way that we can conclude whether the risk is reasonable.

So, who might be out to sue you? To summarize an article from nolo.com [1]:

* An employee
* A landlord
* A supplier
* A customer

To mitigate these risks:

* Don't hire anyone
* Don't lease an office
* Don't buy goods on credit. Buy high quality goods when
you can't afford to have a problem with them.
* Have an "as is" end-user license agreement. Be very
cautious about making service quality guarantees.
Don't sell software that can cause damage or personal
injury.

If you have to do any of the above, it's time to incorporate. (For another take on when it's time to incorporate, read "The When to Incorporate Decision-Matrix" by Ryan Roberts, J.D. [2])

Why I dislike any kind of housing that gets city-level density: I don't like sharing a wall of my dwelling with others. I don't like hearing people easily through my walls. The suburban sprawl grants that.

Yes they would. This is an utterly classic failure to understand averages. The idea that people visit a dozen or so websites regularly doesn't remotely imply that those are the only websites they visit, or even that those are the most valuable websites for them.

Ask HN: Young developer looking for some guidance
I'm currently in my first year of a two year masters degree in software engineering. I'm comfortable with the coursework and am really enjoying it.

Where I feel lost is in my spare time. I have a bookmarks folder with about 200 links to articles, resources, videos, etc. I'm incredibly overwhelmed with the amount of 'stuff' out there; languages, frameworks, tools, and so on. I feel a bit lost every time I sit down at my laptop and try to do something productive.

My short-term goal is to secure an internship/junior position in Europe (Poland) over my next summer break (I live in Aus).

I'm looking for some ideas on what to do in my spare time to make myself the most competitive for an entry-level position.

With only a few months of experience I haven't really been exposed to enough different areas of development to say I want to work in X, Y or Z.

I'm suffering from the fact that pretty much everything interests me. Web dev, data analysis, machine learning, databases, and so on. I think that for me I need someone to pigeon-hole me into an area so that I can self-study in depth and get an internship in this area.

Would some more experienced developers offer some advice? Where did you start? Where would you have liked to start? What are some good ways to kick-off a successful development career?

I hope this wasn't too much of a ramble. Cheers

I'm 28 and frustrated – can I still have programming career?
For past two or three years I have felt very unfulfilled. I have background in video production/editing (Avid, Final Cut, After Effects) with 6+ years of experience, including national TV broadcast.
But for past 4 years that I was employed I wasn't feeling very happy, it took energy out of me. I was so unhappy that I quit my current job few months ago and relocated to Canada to clear my head.
Now that I'm working as a labourer in construction I realize how easy I had it in my old job (I had own office, good salary, recognized by peers etc).

But I wanna enter IT industry, I've been around computers all my life (started on Commodore 64). Since I was 13 I dabbled with web development and I can set up blogs/static sites pretty easily. In January I started to learn to program in Python which you could say was my first real programming experience (I guess HTML, CSS doesn't count).
It's going slow since I do it after work, I don't know anyone now who's a programmer so I go to SO all the time.

Now I'm 28, doing manual labour and dreaming about being a developer. I am just worried that I'm not gonna cut it ... I cannot afford to go study computer science but I have motivation to learn on my own.

I would be SO happy if I could do some entry-level programming. I'd be grateful for all the boring stuff programmers complain about - I'd even take smaller salary just to have experience (but I need to earn to pay for rent).

I just don't know how to do it. I'm feeling kind of scared and depressed about life.

TL;DR I really want to become programmer but I am worried it's too late for me.
The original study claimed that factors other than practice were ultimately not significant, and this study appears to contradict that.

Of course it saves energy if you don't heat the house, that's obvious. What's less obvious to many is that it saves much less than you think if you live in a house in Northern Sweden, heated with electric heat (which I happened to grow up in).
That could be dealt with by beefing up sound insulation in your party walls. Maybe building code needs to be changed to deal with this, but my guess is you just lived in buildings where the architect/contractor got cheap.

ETA: To be fair, the architect/contractor/developer going for the cheap option is pretty common. Especially when it comes to something no one can see like insulation inside walls.

Saying Google and Facebook have built successful businesses around free services is like saying dairy farmers have built successful businesses around offering cows free grass.
I'm pretty sure one of the hallmarks of freedom in the 20th century was the repeal of a constitutional amendment forbidding people to buy 'rotten' grain.

Nothing is wrong with rotten food, it's some of my favourite, everything from alcohol, cheese, bread, etc. I bet you probably eat something that's rotten, and would oppose the government mandating that all food be 'fresh'.

As for unsafe cars I don't see why auto wreckers should be prevented from selling cars, or charities should be prevented from being gifted 'clunkers'.

The only thing that could be wrong with any of those things is being deceptive about the quality of the good, eg, passing off a rebuilt car as new, unpasturized milk as pasturized, etc.

Plans like this would be perfect for my kids, a safe walled-garden until they are old enough to make decisions for themselves. I'm not sure why the FCC needs to prevent the market from offering services like this... I mean I could hack the phone to do the same thing but it would be nice to save on internet at the same time.

So yes, I trust the competitive market far more than the government to provide me with the goods and services I need at a fair and reasonable price. (Note that the current telco situ is about as far away from a competitive market as one can be, the solution is competition, not regulation)
That's cheap and lousy construction, not inherent to sharing a wall.

Your theoretical analysis misses an important physical fact: houses are able to exchange air with the outside world, not just heat. As you heat a normal room, it will expel air in order to maintain constant pressure, and similarly, as you allow a room to cool, outside air will enter again to keep the pressure constant.

There was an article about this in the American Journal of Physics [1, 2] a couple years back, and the authors calculated that heating a room from 273K to 300K (32F to 80F) causes it to expel about 10 percent of the air inside it.

Somewhat surprisingly, the authors don't comment on how relevant this is to the question of when to turn your heater off. The fact that allowing a room to cool draws in cold air from the outside means that the practice is worse than you would naively think, but I don't know when if ever that actually suggests leaving the heater on a constant setting. I'd be very curious to see someone extend the calculation to give an answer.

This even includes some bad police work. Because since the developer didn't post a single app of this type after the initial suspension google could have easily identified all apps and found them all and notified the developer that all apps must be dealt with.

This would be akin to the police having 10 open murders with the same exact weapon, charging the assailant with one and not looking for any other open murders on file.
On a serious note, what would the requirements/steps to move towards this be?

My guess is some combination of:

- Money

- Initial pre-committed residents

- Habitable land

- Management

And then the main thing left, is, I believe, approval?

Which leads to my questions:

- What is the legality? Where is it legal? Where is it illegal? Or if legal, what are the chances/what is needed for approval?

My question is re: Watering your plants and mowing your grass - using the pools, and playgrounds. Do you outsource these, do you enjoy them, how might you use that money otherwise?

Much of my suburban experience is that grass and planting are choirs that are outsourced - and that few people actually use the pools and playgrounds.

I'm a bit frustrated when friends talk of the desire for a pool when they never go to the pool (that always seems empty) that they pay dues for.
