I see problems like this as "points-in-time". There will eventually be a technology based solution to these sorts of things. Early warning systems, collision detection, even just pervasiveness of go-pro cameras as the price point brings it into "standard equipment" territory (thus allowing distinction between negligence and accident).

That doesn't help people who are currently being run over. I ride a motorcycle occasionally and I know that I'm accepting a significantly higher chance of injury or death by riding it. I would love to improve those odds but I don't look to the criminal justice system for it.
He just said "accidents". He didn't say who was at fault.
Rice is a major cause of food poisoning.

http://www.nhs.uk/chq/Pages/Can-reheating-rice-cause-food-po...

> You can get food poisoning from eating reheated rice. However, it's not the reheating that causes the problem but the way the rice has been stored before it was reheated.

> Uncooked rice can contain spores of Bacillus cereus, a bacterium that can cause food poisoning. When the rice is cooked, the spores can survive.

> If the rice is left standing at room temperature, the spores can grow into bacteria. These bacteria will multiply and may produce toxins (poisons) that cause vomiting or diarrhoea.

> The longer cooked rice is left at room temperature, the more likely it is that the bacteria or toxins could make the rice unsafe to eat.

Reheating the rice does kill the bacteria, but does nothing to the toxins.
BTW, I was born and raised here. I spent 8 years living in Germany and 1 year living in Ireland. Afterwards I decided to move back here 8 years ago and don't have regrets. ;)
Because the wildly libertarian China that has state firewall and can cut off the access to the block chain completely will just fall in love with something that could for any reason diminish its ability to have iron grip control over its economy and currency.

If Bitcoin is going to be not fringe it will need wide state support of at least 51% of the world GDP. There is not a single economic bloc that could endorse the loss of the ability to manipulate its own currency.

It is an awesome real time payment system, but crappy as a currency.
You seem to forget that kids are tossed out of schools in the US for playing with toy guns. You can get thrown out for making your food look like a gun.

On the other hand, many of these mass killers are? Kids. The same kids who are never taught how to handle themselves around potential danger or to manage risk and stress.

So, we get a bunch of kids who sit at home a rather playing with their pop-tarts as toy guns, play "FIRST PERSON SHOOTER" video games. Cause why? That's a good way for them to learn how to safely handle firearms?

And we wonder.

I would recommend my hometown for self employed, small companies and freelancers: Bremen/Germany

Bremen was a harbor and shipyard town 30 years ago. Now most shipyards are bankrupt, and the harbor seldom sees big ships.

Rentals are really cheap, e.g. I'm paying Euro208 warm (including heating, water, waste, etc - excluding electricity 64Euros and internet SDSL+Cable ~ 50Euro) for two small rooms plus a big kitchen. So I can smoke at my computer, sleep in a room where I dont smoke and host guests at the kitchen. Houses are also cheap, sometimes only Euro40k.

Bremen is a medium size (500k inhabitants) green city with parks everywhere, and gardens around the houses. You can ride bicycle everywhere. We have a good public transport. Its long and narrow. So regardless where you live, you are in walking distance to the river, and in walking distance to the rural. It basically feels like a suburb, but with good transport, and bicycle lanes.

Internet is cheap and available, e.g. 30mbit cable for Euro30/month or 100mbit cable for Euro40/month. Ryan air is at our airport, so you can fly within Europe for Euro19, if you pick the right time at night for ordering a ticket.

Bremen is a free Hanse city and friendly to foreigners. One of our mottos are "Am nettesten sind die Zugereisten" (the nicest people here are from outside). Citizen here are traditional left wing, so neo-nazi's have a very hard stand, and are seldom seen in public.

Bremen has a friendly police, and a sane drug policy. You can smoke marijuana at the dike, and the police will greet you while riding bicycle, and its usual that junkies are sitting in a small park behind the police station. Especially Bremen-Nord (north part of Bremen) has a very friendly small tax office, with great newbie support, and public servants who care for your business.

The drawbacks are high unemployment, low wages, and its nearly impossible to get a developers job outside of the military industrial complex. Also others claim that we are cold. Its hard to learn new people in a pub, but thats easier if you are from outside Germany. But we prefer to gather in clubs (e.g. we have 2 hacker spaces). We have several sport clubs, that are affordable, e.g. most working class sailing clubs costs Euro100/year for adults with own yachts. We often joke that Bremen has always good weather: In winter its warm and rainy, and in summer its raining and warm, thanks to gulf stream.
> Easier - the credit card process is already about as easy as is possible

Credit cards requires giving a physical card to someone when ordering offline, or typing a series of numbers when ordering online. There's a lot of room for improvement with Bitcoin.

In addition to that, Bitcoin can make some less standard payments easier, like splitting a payment between multiple users, using an arbiter for the transaction, micro payments, etc

> Cheaper - the credit card process costs the consumer nothing

Perhaps the consumer doesn't pay for it, but there's significant cost for the merchant that can be saved with Bitcoin.

edit: which could also effect the total price the merchant is asking for, giving some of the cost reduction to the consumer

> Safer - the credit card process has substantial fraud protections for the consumer, but bitcoin by design does not have those fraud protections, so I don't see any way bitcoin could ever be safer.

Bitcoin doesn't have fraud protections because its outside the scope of what Bitcoin is. Its like saying that the US dollar doesn't have fraud protection. Companies can be built around Bitcoin to provide that service for a fee.

In addition to that, its actually much harder to steal (locally stored [1]) Bitcoin private keys than it is to steal credit cards. When an attacker breaks into a service that accepts credit cards, he can easily copy and re-use the credit card numbers because the one accepting the payment has everything needed to make more payments. With Bitcoin, the one accepting the payments can't make more payments. An attacker has to gain access to the consumer computer that stores the private keys.

In other words - gaining access to a website that has 100,000 credit cards gives you a lot of power. Gaining access to a website that received 100,000 Bitcoin payments gives you nothing. You'd have to break into 100,000 individual computers.

[1] I'm assuming here that people either use local Bitcoin clients or m-of-n transaction where one key is stored locally. There are online wallets that stores private keys that creates significant security risks, but at least I have a choice as a Bitcoin user.

The + in +1 is bound tightly to the number like the - in -1. Think of it as meaning "positive," not addition.

Also, Hy's lexing appears to have an interesting feature where you don't always need a space to delimit things, so []+1 is automagically broken up into [] and +1. Here are some other examples where it breaks things up:

=> []"foo"3"hey"["wakka""wakka"]
[]
u'foo'
3
u'hey'
[u'wakka', u'wakka']

=> (+[1][2][3])
[1, 2, 3]

So without parens, []+1 is like []; +1; in Python and prints out the same result. With parens, the first token of ([]+1) is treated as a function (as would be typical in Lisp) so it tries to execute the Python [](+1), and you get the error that [] isn't callable.

So []+1 ran, but not for the obvious reasons. I'm basically poking at the REPL like you to try and puzzle this out; if you want to dig further, you could look at Hy's docs or source or contact the folks that wrote it.

Edit: an additional detail, not sure if it's informative or just confusing-- "+ 1" is apparently lexed by Hy as two items, not as positive 1:

=> [] + 1
[]
Traceback (most recent call last):

I see them too. I also see them got ticketed heavily and some even lost the privilege to drive. But I can't say that vast majority of cars run stop signs.

Your link is not relevant, sorry.
This summer I was hit by a truck pulling a wide trailer. The truck overpassed me, but the driver neglected the fact that his trailer was about a foot wider than his truck. It smashed me from behind and laid me out on the pavement. I was lucky enough to not fall under the trailer, but still smashed hard onto the road and nearby sidewalk. My helmet, without a doubt, saved me from a serious head injury. I walked away with some extensive road rash and a minor concussion.

The author makes all of the relevant points. When I first moved to SV, I bought a nice bike and rode it around for awhile. Then I started to notice the utter lack of attention to cyclists, even those such as myself who rode with a helmet and obeyed all of the traffic laws. You're just invisible.

Now in SF, I see the same problem with drivers but I also see cyclists acting generally like assholes, ignoring traffic laws and yelling at pedestrians to get out of the way as they run red lights. That sort of behavior costs cyclists, collectively, a lot of empathy points even if most individuals don't behave that way.
Sometimes, I feel like I live in the future.

This article is a string of anecdotes presented as a trend. Where's the hard data?

In any case, the truth is, accidents do happen. What would throwing the teenager in the article (who was in an accident with a cyclist) in jail accomplish? Should getting in an accident be a life-ending event?

Why is a single entity needed to back a currency. Isn't bitcoin just crowd-funded vs. the the US is the dollar's vc backer? For it to truly crash, everyone who uses it for different reasons would have to decide it is worth less.

Bitcoin is a protocol for money. Protocols, once they have acceptance have a pretty great shelf life. See http, tcp/ip. So long as they get the job done, there's a disincentive to replace them once established.

Yes, definitely a big problem in the UK too. Although I think support for cycling is perhaps more cross-party than in the US, at least in the political elite. Both the Conservative PM and Mayor of London are nominally pro-bike, also The Times (centre-right paper for those from outside the UK) ran a major campaign on cycle safety, after one of their journalists was killed:

http://epetitions.direct.gov.uk/petitions/49196

Although certainly their freedom to do something serious about the issue is restricted by the anti-metropolitan, anti-liberal vroom vroom demographic.

> If cycling is to ever become safe, cities need to start embracing the bike like they do in the Netherlands, but it's no easy task.

On that topic, this mini-documentary is worthwhile looking at:

>> "I got run over from behind by an MTA bus in New York several years ago and the bus driver drove away. I called the local police precinct"

What do you mean you got run over from behind? When I picture that collision the cyclist would be killed or horribly injured. Certainly not able to call the police - and if able to call anyone they would probably call an ambulance.

I'm not doubting you, just confused by the way you've stated it.
I cycle occasionally and pretty much 1 journey in 10 I'm either hit by or have a scary near-miss with a car driver.
Considering that my comment was a direct refutation of this premise, I'm not sure why you posted this.
The batteries are located under the car, and their base plate is more armored than your usual car undercarriage.

edit: floor, floor -> base plate, undercarriage. Thanks grinich for improving my vocabulary.
When you say "running stop signs", do you mean a rolling slow-down/speed up if they're the first at the intersection? I do that all the time, not sure if it's legal but it's a pain to stop fully. With cars around I always stop, especially in SF I'd be insane not to.
Perhaps not as inventors directly, but they could certainly believe the patents they are buying are innovative. (That's why they bought them! (supposedly))

In an abstract sense, patent aggregators (to coin a term) are not inherently bad. A small inventor faces a number of obstacles and risks marketing and protecting a patent (see linked story). Selling the patent to a middleman guarantees cash today. For many people, $1 million today is better than $10 million in ten years. That said, the implementation leaves a lot to be desired.
Sounds great, I would certainly like to hear more about it. Could you drop me a line via the email in my profile please?
Hopefully self driving car are on the way ;)
I can't remember the last time I saw a car run a red light that wasn't just squeaking by a yellow. I can remember the last time I saw a bicycle do this, it was yesterday and the guy didn't even pretend to stop or care as he obstructed traffic that had the right of way.

And not to mention that I see roughly one thousand times (literally) more cars than bicycles on the road.

I don't doubt that there is a lot of confirmation bias going on in this discussion. But there's almost certainly some substantial differences in behavior going on as well.

Bicyclists generally feel more entitled not to stop for stoplights when they feel it's safe to proceed. I've run lights on the bicycle myself, although I always stop, wait long enough to be sure the light isn't going to change on its own, and proceed carefully after checking for traffic. Quite a lot of bicyclists seem to think that the fact that their vehicles are human-powered means they shouldn't have to stop unless it's absolutely necessary.

On the flip side, I'm sure bicyclists violate the speed limit way less often. I'm sure they kill many fewer pedestrians too.

I think for right now, people would be too scared to wear something that could potentially explode and cover their eyes.

If they prove that these systems never accidentally go off, I think they should have a full head version that protects the full face too; or at least cover a much higher percentage of the face, maybe leaving only the eyes uncovered.
Helmets protect you. I slid down a street and my head bounced on the pavement - without a helmet I would have been much worse off. The road rash was enough. Another incident was a truck mirror that grazed my helmet. Nothing major, but in all, the helmet does its job.
I had an accident recently as a cyclist with a vehicle, and I thank my helmet a lot for my lack of injury.

The vehicle was a van, and turned right across me going straight (which normally I'd see clearly and avoid, but the way they hesitated implied they'd seen me so I rolled through. Alas.) I'd wager I was going around 20mph/30kph as I hit the side panel. Hips/shoulders first, then I felt my head whiplash into it. Without a helmet, I'd expect at least a mild concussion. With a helmet, I was able to roll away relatively unscathed (minor cuts/bruises) after we exchanged details.

Helmets can help at all/many speeds. They're not a perfect solution, but they're great sometimes. Don't discount them so bluntly :)
The drag is bad enough---somewhat chaotic, hard to compute due to atmospheric variation---but I bet they could give a reasonably good estimate as long as it remains in one piece.

The problem is, the moment it starts to break up, all bets are off, because we don't know which pieces will break off first, how large the respective sub-pieces will be, and so on; and each break could send one or more of the pieces into a tumble and/or heat up some other part more than another, which affects chances on further breakage, etc, etc, etc. Basically, once it starts breaking up, the system goes from "sort of unpredictable" to "wildly chaotic".
You would be more likely to see the cyclist if you were faced with jail time for not seeing him.

There is something deeply wrong with the attitude of "whoops, didn't see him, guess he's dead now, YOLO."
It's no surprise the author of this piece is from San Francisco. SF is a particularly dangerous city to cycle in, at least for commuters. Riding on the main drags of Market street, Mission, and others is exceedingly dangerous, since drivers are reckless and you're competing with MUNI buses, streetcars, and in packed cycling lanes.

I'm originally from Portland, which is a cyclist's heaven for a major city, but there's still too much competition with cars. I've also spent time in small towns like Davis, which is probably the cycling capital of the States. The only solution I can see for really safe cycling is to create cycling-only lanes that don't compete with cars and pedestrians.
I could see merchants who give favorable pricing for cash giving the same type of pricing for bitcoin. And ones who don't accept credit cards because of the cut taking it also...
Cyclists running red lights are a big problem in LA. I am very much in favor of cycling, but you have to follow the laws. I know it is a pain in the ass to stop at every stoplight when you have to use your own muscles to accelerate, but you have to do it.
> pedestrians alike just aren't looking

You mentioned you obey the law so you probably don't do this. Even if the law does not prohibit riding on the sidewalk, you should never ride on the sidewalk.

Just wanted to take this time to remind everyone that bicycles do not belong on the sidewalk.
Every time you write a refinement on a type, you're actually writing a contract. You can gracefully move between types and contracts this way, and also between thinking of them as checked assertions vs tested ones. The goal is to make this migration more and more seamless.

If you strike the cells, they can be short circuited, leading to heating. Lithium cells can experience thermal runaway [http://en.wikipedia.org/wiki/Thermal_runaway#Batteries] when they're failing, heating adjacent cells causing them to fail. This is why cells are compartmentalized. Think of them like properly engineering bulkheads on a ship. If certain compartments fail, others are safely isolated.

The problem is, as long as drivers demand range with electric vehicles, and energy storage is much less than liquid petroleum, the bottom of the vehicle is the only place that large, heavy pack arrangement can go. You make the tradeoff: How much armoring needs to take place to avoid the most common damage/failure scenarios.

I have no doubt Tesla is learning quickly from these events, and is plaining alternate or improved methods to armor the pack from road debris and damage.
I've spent tons of time in Greenville. The wholly-walkable downtown hosts lots of restaurants (recommended: The Lazy Goat), coffee shops, the Greenville Symphony Orchestra, and an extensive park along the river. Local breweries, nearby colleges - everything you'd expect from a small city renaissance, but Greenville's started 10 years early and is pretty well along now.
I think this is the core of the discrepancy. Cyclists are so vulnerable that a half-second of inattention from either the driver or the cyclist can result in death.

Many of the errors that grievously injure cyclists would have resulted in a broken mirror and scratched paint, had it been car-on-car.

It seems likely to me jurors are recognizing this, and basing their decisions on actions rather that consequences. Which is not necessarily all that ridiculous.
I find it funny that you're complaining about relevance when you're trying to brandish as damning a document (from a completely unrelated school, no less) where you can see "the following guidelines are intended to apply to all gatherings under the auspices of the Faculty of Arts and Sciences" on the first page. It makes no claims as to the public forum--it makes no claims as to the classroom, even, let alone anything outside of their auspices!

You may find what I said trivially true. I find what you say somewhere much closer to 'dishonest'.
what are the VISA requirements like for someone from a western country (say, the US or Canada)? If I wanted to live in Germany for a full year, is there a way to do so working independently (i.e. without a German corporation sponsoring a work VISA)?

thanks.
Quite unfair. When I commuted by bike in SF for a couple years, I wore hi-vis clothing, front and rear lights even when it wasn't dark yet (especially at dusk!), and stuck to designated bike routes with calmer traffic when possible. And every day I saw hundreds of other cyclists just like me who didn't have a death wish.

The (small-y) yahoos who ride dangerously certainly stand out more, but it's depressing to have folks like you throw up their hands and say, effectively: Too bad there's nothing we can do to make cycling safer, since too many cyclists just "want to die".
Water? On an electrical fire? Caused by Lithium-based chemistry? Not smart?

Tesla's make up less than 0.008% of the US passenger car fleet. Perhaps emergency workers are simply not aware of how to properly deal with electric vehicle accidents? Formula 1 had to deal with this as KERS starter to be introduced. I would be nowhere near a 375 Volt DC battery pack playing with water.
