Huh? Drivers are gatekeepers that let people onto the bus and validate that the people that enter the bus have tickets.

If people don't respect what the driver says, the driver should stop the bus, and call security and then not move until the issue is resolved. There should be no tolerance at all for people that threatens the driver.

Sure it is. But I won't use Java for web stuff. I might use it for some background services, but for regular CRUD functionality, Java buys me nothing. I generally use Python(Flask)/Jinja2/Flask-SqlAlchemy. Flask is intuitive; Jinja2 is pleasant and fast; Flask-SQLAlchemy is concise with the option of exploring the raw power of SQLAlchemy. For regular use cases, nothing in Java beats this combination. I have looked at Play; it comes closer but it's still not there.

Checkout this toy benchmark that was doing the rounds 2 months ago https://github.com/grahamking/Key-Value-Polyglot The naive python solution https://github.com/grahamking/Key-Value-Polyglot/blob/master... performs dog slow. Java has real threads, JIT; but guess what, the naive Java solution still is dog slow https://github.com/grahamking/Key-Value-Polyglot/blob/master...

My specialized python solutions are magnitudes of times faster than both naive Python and Java solutions:

https://github.com/rahulkmr/Key-Value-Polyglot/blob/master/m...
https://github.com/rahulkmr/Key-Value-Polyglot/blob/master/m...

The naive solutions were taking around 20 seconds to do 500 writes followed by 500 reads. My changed solution does 5000 writes followed by 5000 reads in under 2 seconds. The 500 and 5000 aren't typos - the naive solutions was taking about 20 seconds for 1000 operations, whereas tailored solution was doing 10000 operations under 2 seconds.

I get it that this is an IO bound problem, and naturally an epoll based solution will totally smoke a thread-per-request solution, but that's the point I am trying to make. If at the end of the day, intuitive solutions don't work and I have to do custom implementations, I am not getting much out of using Java. I might use it for something which is CPU bound about 70% of the time, but anything other than that, the pains far outweigh benefits.
What I'm saying is that a tool for webdev that wants to stand any chance of becoming popular must be able say to developers: here's the familiar MVC structure, you write your models, you create your views (hopefully out of set of widgets that are highly replaceable/customizable at any moment), we take care of talking to the server, saving your models to the storage and syncing between different instances of an app. Sure, there are problems to solve here, but since everybody does it their own way at the moment, I don't see no reason why we can't have a framework that solves them for you.
In England we do have bins in stations, but now days they generally consist of a transparent bin bag with no surrounding material (e.g. held open by a loop at the top that's attached to a wall). I believe the logic is that it makes it harder to hide a bomb in them, though whether this is fact or just commonly quoted myth I have no idea.
It depends, in the best case 15 seconds. But usually a few minutes and when the Mars is behind the sun, you can't use light.

You are not really cut out, but the communication is not interactive and you can only play round based online games.
I still hope quantum entanglement can be used as a communication tool.
No, but I live in a country where this is how it works. Drivers here in sweden are responsible for cleaning the bus during the day (with a more thorough cleaning at the garage that the driver isn't responsible for, afaik), and he has enough authority to eject people off the bus if they are violating rules, or to not let them on if they would violate rules.

I don't know what the skeptics think, but to me, the fact that at least 2 wealthy individuals or entities have invested $100k in 360-FPGA farms should send a signal that at least some consider Bitcoin sufficiently reliable, trusted, and stable to warrant this kind of investment. They put their money where their mouth is.

I will soon write a blog post documenting the numerous other FPGA board vendors that started designing custom boards targetting the Bitcoin mining market.

I think the author gives the federal government too much credit. Which is more likely: the government out-witted people by thinking ahead and foreseeing people would break the law, so they write a law to counter it; or, they left the law on the books from when smoking was legal and never amended it? I think the latter.
I'm still waiting for Google to stop asking for my mobile numbers.

Roughly this farm makes $10k per month.

110e9 (hash/sec) * 3600 (sec/hour) * 730 (hour/month) / (2^32 * 1733208 (current difficulty factor)) * 50 (coins/block) * 5.1 (current exchange rate: usd/coin) = $9903 per month

Minus about $730/month in electricity for the 10kW it consumes, assuming an average worldwide rate of $0.10/kWh.
Thanks, I'll definitely use this from now on!

EDIT: I upvoted the post, and now it's no longer in gray. So, it was just one downvote.

Why the downvotes? Parent post is just pointing out sites which he/she knows to be using Python and/or Django, some of which are incorrect(Gmail?), or are giving the impression that they run on Python when only small sub-projects are using it(LinkedIn?, Amazon?). There are some mistakes, but on a whole, I don't see anything wrong with someone pointing out something relevant to the discussion, even if it involves bragging about something he is associated with.

Regular exercise really is the solution. I know exercise makes me more hungry to the point where everything tastes good. And if you've put in enough effort, you will not want to waste that by eating junk. Solid exercise involves a lot of physical pain and once you learn to deal with that your willpower will be off the charts and sticking to the right food will be a breeze.

I was out of shape until I did P90X last summer and now I'm a different person altogether. You would be surprised how much can be done in three months of proper hard work. But it does not have to be a full blown fitness program. People aren't always aware of the options. When thinking of weight loss, jogging is the first thing that pops to mind. I have always found it extremely challenging mentally and I was never even overweight. Commit yourself to a few basketball games a week, or a cycle, a climb, a hike, skiing, whatever you enjoy. If you push that little bit harder every time and get some sweat going, get your heart racing, you will be surprised what it will do to your body.

Also a tip for motivation is to focus on performance. If you can run faster and farther, jump higher or feel better, just keep progressing and the weight will come down naturally.

How sedentary does one have to be to be at risk of a heart attack at age 32? This story seemed a bit odd to me, like it could have been entirely contrived. I certainly hope it wasn't.

Exercise (really just walking and getting up on a daily basis) is vitally important, and for those of us OCD enough to program or game 12 to 18 hours straight, it is important to remember such facts.
Great, thanks for setting this up again! Will definitely be there.

It is trippy in a pretty literal sense. I'd wager this is the same mechanism that screws up faces for you when you take psychedelic drugs, except with that you can be staring right at the face and still see it that way. The effect is very similar.

Babies have to learn to interpret human faces so that they ignore the parts that don't matter and focus only on what typically distinguishes them. They manage to do it pretty quickly, but perhaps this is how we see faces for the first few days after we're born.

Las mejores Anecdotas con tu Beca Mec en Estados Unidos
Verano anecdotico en Miami 2011
Enhorabuena a todos los que tengan los requisitos de las Becas MEC. Yo estuve hace un par de veranos en Miami con mi Beca MEC y disfrute de lo lindo.Escribo para que nos os pase lo mismo que a mí.

Soy una persona despistadilla y aunque en toda la información que recibí sobre mi curso de inglés y de la beca MEC aprecia la diferencia horaria yo no me enteraba. Realmente mi problema era que tengo un reloj que es muy difícil de cambiar la hora y por no tocarlo allí me vi llegando la primera a mi curso, claro me levantaba unas cuantas horas antes.

Todas las noches hacía el calculo mental pero se ve que las matemáticas no son lo mio. No había día que no me equivocara. Al final lo que hice fue quitarme el reloj e ir preguntando la hora a todo el mundo, pero claro para levantarme tenía que ponerme la alarma y no había manera de hacer el calculo. Hasta que se lo comente a otro compañero de la becas MEC y me la programo él.

Como podéis imaginar mi problema con el cambio horario fue mas allá porque al volver a casa, la alarma me sonaba a las 13 de la tarde y ahora llegaba tarde a todos lados porque además de despistada soy dormilona.
He vuelto a solicitar la Beca Mec, espero que me la concedan porque con esto de los recortes???? Esta vez tengo un móvil con despertador y que se cambia la hora automáticamente así que se acabo mi calvario de calcular el cambio horario. Este año me gustaría ir a Boston.
A typical two-stroke engine uses fuel that has lubricant mixed in. Tetraethyllead used to be added to petrol to allow higher compression ratios, increasing fuel efficiency.

Partly correct. Trash cans were removed to prevent people hiding bombs in them. They are now coming back, both as transparent plastic bags, and also as bomb-proof cans (which are designed to direct the explosion upwards, and resist sideways rupture).
Wait, what? it's a sign that it's fundamentally unfair and easily gamed that the market is responding to the incentives implicit in the design? Miners don't just suck away all the value in the system, they are the value in the system; no mining, no blockchain, no blockchain, no transactions.

More mining, more secure blockchain, etc.

LEAP: accurate real-time motion tracking
The driver isn't a gatekeeper or tollbooth collector. They stop, you pay your fare. You don't pay the fare they aren't going to argue with you, just pull off to the next stop. Because the bus driver has a schedule to keep and if he has to stop the bus for every minor infraction (and eating on the bus is very far down that list) than the schedule becomes unreliable, people stop taking the bus, and then revenue drops.

And all of this could have been avoided with a trashcan on the bus.

If you've watched anything on youtube you'll see that people escalate a situation for some of the stupidest things. The world is full of crazy people and they drive or take the bus too.
Paul Graham's indications for the content of Hacker News:

What to Submit

On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.

Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.
