If you think optimal (in your perspective) hand dryers took this long, contrast this against the wheeled luggage, that took quite a long time to catch on (http://www.travelproluggageblog.com/2010/06/luggage/the-hist...) as late as 1989!

Perhaps, it's just as conceivable that regardless of how well the dryers worked, consumers could have just wanted the option for paper towels. And even if the dryers are fast, I am sure the line doesn't help. Of course, I am sure the ladies room would have even worse time with just one effective albeit expensive dryer because of the already nasty wait times on average.
This is one instance where C++ and C are, indeed, the same. However, the languages do have their differences, so I would caution those developers who don't tend to read standards not to assume that C and C++ will behave identically when given valid C code. Obviously, having referenced the C++ standard yourself, you are aware of such caveats.

Your confidence in your abilities provide only an illusion of certainty. Maybe if you had enough time you could fix any problems that occur with open source software, but when you have a deadline it's nice to have experts to help you. You can find open source experts, but with a commercially supported product there is a much clearer chain of responsibility.
Personally my sympathies are with Penrose and Bohr.
Over here in China, as you might expect, Traditional Chinese Medicine (TCM) is quite popular. But after spending a year teaching in a TCM provincial level university, and talking to a number of the lecturers is it even real? A good few of the lecturers have been disciplined for complaining that TCM is for want of a better term "a load of crap".

If the people teaching & practicing it think it's snake oil what does that say about it.

And why is it called Traditional Chinese Medicine, why not just call it medicine if it works?
I much prefer Zeno's Republic, where everyone is equal but strives to be wise.

Really, I think that there is no such thing as a perfect government, only a perfect citizenry, because the power of a government is always derived from the people within it. A philosopher king would not be able to maintain power unless either A) he was omnipotent or B) the people allowed him to remain in power.

No it's not. Someone liking or disliking a product is based on their own perception of it's value. There will never be universal agreement on whether a product is good. Who's to say you're right vs. your neighbor who says the product is crap? How can you possibly use that as the basis for an investment decision?

I wish you the best of luck with that investment strategy. To look at a company and say "Hmmm, I like their product. I'll buy the stock!" is horrible advice to give. That's what amateurs do. You haven't looked at the underlying fundamentals of the company. You haven't looked at the management team. You haven't looked at it's current valuation. You have no basis to say that investment is going to succeed -- it could be wildly overvalued, but you wouldn't know because you're investing based on emotion and feelings, not based on facts.
It do interested me tought, especially how they designed their hardware architecture to match their need.

What would stop special interests from buying a new candidate every cycle? They help the candidate get elected, the candidate crafts legislation to the special interests' benefit, then the special interest hires them as a lobbyist when their term is over.
> That's one way to make NYC even less affordable and friendly to tourists on a budget.

But that is a valid concern I suppose -- does NYC benefit from tourists on a budget? If it doesn't then it might make sense to keep them out so tourists "not on a budget" can have more space, visit more often, and consequently spend more money.

I can see how tourists on a budget would not be welcome in many cities. Some places rely on selling overpriced services and items to tourists and rely on tourists coming in and just throwing money around. So making legislation to accommodate certain visitors, but discourage others, kind of makes sense.

I agree. And choice is even greater in Switzerland. You and your neighbors can even move your neighborhood to a different cantons.

These laws come from DC and the states have lost a lot of the power they had initially. The federal government had a list of powers. They call them the enumerated powers. The states had everything else.

And the citizens could leave a state if they didn't like it. A lot easier to do than leaving the country.

Which is why local laws are not really that oppressive, even if they are. But federal law is all encompassing and difficult for you to influence. They can pretty much ignore the individual and usually do, except when they need something to grandstand about.
Heh, thanks for the tip, we'll see if that works for me next time. I am definitely one of the adduser challenged.

The first time I read about something like this I was outraged. "How dare they, the government is blocking people's ability to do business". Then, after some careful thought I started to agree with this ban. Basically I put myself in the shoes of a resident next to a building being used as an illegal hotel. The people do not have the proper permits. Obviously they are not licensed. The fact that there is always new people coming and going in what is supposed to be a residential area can cause problems. And I say this as a resident of NYC. Living here I never realized that it was so expensive to visit NYC. Sorry to be cynical but I guess it sucks to be you if you want to visit NYC and are broke.

Notice that the person doing this illegal business is the only one benefiting from it. The community will not get any of the taxes that it is supposed to get which are in turn used to maintain the streets, pick the trash, pay police officers patrolling the area, etc. etc. Essentially, the community is paying for an illegal business.
> Building a codec into the browser doesn't get you out of having to explain to your parents how to get codecs on their system.

Yes it does; I don't have to explain how to install codecs because my parents don't download videos, because all the videos they want to watch are embedded in web pages (today via Flash, tomorrow HTML5).

Supposing they did want to download a video file for some reason, then ideally the browser's video player would be just as nice as the OS one, and the browser would take over that duty. That hasn't happened yet, but it will, and the end of that road is Chrome OS. The desktop OS with trusted native apps installed on a local filesystem is becoming obsolete. The future is sandboxed apps cached via HTTP.
Michael Larson - The man who reverse engineered a game show
Lots of people seem to be thinking that all the big hotel chains are being evil by lobbing this kind of anti-competitive legislature out to kill airbnb and the like. And while that maybe be true, you also have to realize that governments would much rather prefer people stay in real hotels regardless of what the hotel industry thinks. Local governments get a lot of money off of occupancy taxes, as well as tax off of the employment of those in the service industries. How many airbnb hosts in NYC are paying occupancy taxes? What about reporting income? My guess: not too many. And this is completely ignoring zoning regulations that these self-serve hotels trample upon.

Im going to guess that these laws will become more prevalent soon unless airbnb & co start become proactive about keeping track of all the relevant taxation.
Of course, but by "some companies", I was mainly referring to Google/Microsoft/Amazon/et al.

I would agree that for the vast majority of companies, having an attitude like that is a losing proposition.
I would hope that the 76 who didn't have proper credentials were at least evaluated on performance before their dismissal. If any of those 76 were actually excellent teachers, firing them on credentials alone without offering the opportunity to earn their credentials while working is a tragic loss, and smells of union-inspired member protection.

Disclaimer: both of my parents are teachers.
Besides internal use, I would also add App Engine to the list. Of course, he also forgot to mention that Google has the BDFL a.k.a Guido :-)

Ask HN: GUI in Scala/Groovy/Clojure
Last time I had to deal with Java was 2005 and I forgot almost everything about it since then.

Today I need to build a GUI app on the top of Java. I guess it is better to use one of Scala/Groovy/Clojure languages.

The question is: which of them is better for desktop GUI programming? My program will transform and display a series of jpeg/png files + there will be ~10 dialogs (with tons of options in each with all possible widgets).

The main requirement is compactness: I hate to write a dozen lines of code only to draw a simple frame with a button. My background in GUI is (mostly) Tcl/Tk and GTK+.

Thanks in advance.
"[S]tudy," in that sentence, was supposed to mean "studying" rather than a paper. My intent was to separate the sorts of books that you might read end to end from the sort that sit on a shelf until you need to extract some specific piece of information from them.

It's clear to me now that I've done a terrible job of this poll, so perhaps I'll try it again tomorrow with a clearer view and delete this version.

Most of the people that gripe about Perl think that nothing good ever came from it. (At least in my experience)

I was in NYC with my team this past Jan, trying to raise money with a few angels in the area. The three of us decided to rent a furnished apartment to save money. I was pleasantly surprised by the amount of space this decision afforded. There was plenty of desk space in the unit and while there weren't enough beds for each of us the couches made due just fine.

The landlord explained that they were having trouble leasing the apartment, and that they were falling back on relying on this sort of rental to help cover the cost of the space. It's a shame this won't be an option in the future, both for poor entrepreneurs and landlords.

By the end of it, you'll probably know more about the subject than I do. I'm a master's* student on my last semester. I don't actually do any work in the area, but I've taken a couple classes on neural networks and a class on genetic algorithms. Those were my major focus.

My preferred neural network structure/design is NEAT (developed by Dr. Kenneth Stanley) and its various derivatives. If I were to work more with neural networks, I would work to expand that design. (my work interests have expanded to include other stochastic algorithms, such as Monte Carlo Localization, as well)

You are missing one important point: most people affected by this ban are individuals, renting out one room at a time, maybe two. I have a hard time believing this generates any kind of noticeable "coming and going".

In fact, tolerating the rental of a single room per household strikes me as a good way of separating the wheat from the chaff.

does NYC benefit from tourists on a budget

Any tourists will bring tax revenues into the city by eating at restaurants, visiting museums and events and generally purchasing goods and services.

"not on a budget" can have more space, visit more often, and consequently spend more money.

If any place in the world operated purely under this assumption, then you would never have urban centers like New York to begin with. Consider that if the demand for hotels was so high that there was no longer enough rooms for tourists that more hotels would be built.

Some places rely on selling overpriced services and items to tourists and rely on tourists coming in and just throwing money around. So making legislation to accommodate certain visitors, but discourage others, kind of makes sense.

It really makes sense for hotel firms, who are likely the ones behind the vast lobbying efforts that helped to implement this law in the first place. They are the ones who stand to garner the extra revenues to be had from tourists who no longer have the option to AirBnB and must instead pay for high priced hotels.

The only way in which this should improve New York's revenues as a government entity is through the room taxes assessed on hotels as opposed to AirBnB-style operations.

This problem, however, could have been remedied without outright outlawing of the practice which seems to infringe on the rights of many property owners who AirBnB in a reasonable fashion (i.e. not purpose built illegal hotels).

Apparently, also in art, the last 10% take 90% of the time.
I have no idea what the breakdown of tax allocation looks like in NYC/NY state, but I'm not sure your last statement is correct. I assume the person doing this illegal business is still paying property tax and state income tax? If not, then that's a problem with the IRS, not a housing authority.
The tax for a residential building and for a hotel are not the same.
So you don't like any programming language, then? Because given a programming language, I can definitely write bad code in more than six ways.

(Have you seen the Python that non-programmers write? Holy shit! It's like 1980s Perl, but worse! Almost like bad code has nothing to do with language, and everything to do with programming ability.)
It's interesting that he mentions how OOP is important, but not that Perl has one of the most featureful object systems in existence.
League of Legends is a fun game - it's the only reason I still have a windows install. Good job on making the game awesome.
You could spend $100+ on a hotel for the night, or spend around $30 or less on a temp place. The money you save CAN be used for touristy things. That's $70 a day that can thrown somewhere else besides for shelter. They could be out partying, trying out food places, buying things, etc. This is just the savings from not staying at a hotel..

A tourist who stays at a hotel ($100/night) might only have budgeted $50/day to spend outside of hotel costs.

A cheap tourist could budget $100/day, stay at a temp place and still get more out of NYC than someone who budgeted $150/day and stayed at a hotel.
$perl += 1;
I also see this as a problem though. Most likely the person doing this is not the owner of the apartment. I wonder how the original landlords feel about this. Maybe they just don't care, who knows. Seems wrong to be using their apartment for this when they never agreed to it.
So why is Perl so unfashionable? He mentions OO and readability, but if Perl has "one of the most featureful object systems in existence", does that leave just readability? I'm curious (as someone who knows very little about Perl) what the actual reasons are for Python and Ruby having stolen so much of Perl's thunder.

On top of nostrademons advice, find people who you (and they) can work along with. They will be your family and so you better get along with them well or else perish. If you are building a technology based company, you should be very clear to your cofounder(s) (hopefully some smart technical ones) about what you can bring to the table.

Honestly, talk about your idea and see if people really care about it enough.

Of course, I've also seen this - some really smart business folks writing long business plans and then tell me, "This is our product X [a web based solution often times] that we're trying to build, there's a need for it, etc... Oh, and we just need a website - we could maybe use a part time web developer?" Of course, there is nothing wrong with not knowing where to start, but it's really good to test your assumptions from the get go.

And it doesn't hurt to have advisors - as in people who have done this kind of stuff before. You'd be amazed how much people can share over a piece of pastry and coffee :-)
Scheme has a Lispy syntax (good or bad depending on where you're standing, but probably not neutral) and doesn't have static type inference, which is the whole point of the article. Haskell is just enormously complex for anyone who doesn't have a very strong background in maths and category theory. Seriously, it's an amazingly cool language, but unless you can look at ST and not feel a little confused at first, you won't be able to shake the feeling that Haskell is smarter than you are.

OCaml is a reasonable middle path. It has a lot in common with Haskell (H-M typing, ML syntax, pattern matching) and is largely pure, but doesn't absolutely force purity on a language level the same way Haskell does. Strictness is the default, with laziness as an option, so there are no surprising space leaks. IO is performed with IO functions, not with some bizarre monad that is the description of an action that would be performed.
I realize that, but it's still extra income that gets taxed back to the government
One more thought: the state expects this to plug a leak in tax revenue. I think they are vastly underestimating the relief these rentals represented: losing that extra income might mean foreclosure for a lot of people.

Plugging a leak, really? I call it shooting the life raft.
That's correct. Tear-off tabs were added to Firefox in version 3.5, which was released several months after Chrome 1.0.

Wow, a law! This will stop the "problem" just like the drug laws solved the drug problem. Nobody wants drugs anymore, and even if they did, it would be impossible to obtain them. Same for short-term rentals, thanks to this!

It will make Airbnb business more difficult in NYC. Sure, it hasn't stopped the drug Mafias but it sure makes their job harder and brings the price of drugs up (they love this though). This will probably bring the price of short term rentals up. Enough perhaps to satisfy the hotels. Which maybe is all they want.

I would agree - the money spent on hotels probably doesn't stay as local as money spent on food and entertainment.

Really an unrelated issue though.
