I choose to ignore this "advice".

I've hit my head a few times while getting into bike accidents.

The first time, I was wearing a helmet. Mostly landed on my face, but the helmet broke and I was fine. (An ambulance was driving by and took me to the hospital as a precautionary measure. Somewhat convenient.)

The second time, I was riding a CitiBike without a helmet. I hit a pothole and somehow ended up landing on my head. I don't really remember much, except laying in the middle of the road for a few minutes trying to figure out what happened. (I do remember being pretty sure that this was the end. But I decided I didn't want to get charged for the missing bike, so got up anyway.)

The third time I was wearing a helmet again, but I landed on my hands. It was winter so I was wearing gloves with leather palms, and just kind of slid for a while. It was great. I rode 40 more miles after that one. (And I'm definitely a fan of gloves!)

Wear a helmet. It's pretty easy to fall off your bike, and you don't really want to injure your head.
Since we're passing around flawed statistics, I'd like to share some anecdotes:

1. Just 2 months ago, my little sister was riding on a bike with no helmet. She was struck by a car. She flew off the bike, puncturing a lung, breaking a clavicle, several bones in her face, ribs, road rash, etc. She stopped breathing at the scene. After 1 week on the ventilator, she began breathing on her own. We knew there would likely be brain damage. She woke up confused and showing most of the signs of traumatic brain injury. Fortunately just a couple months later she's done with physical therapy. Due to nerve damage she will always have a little trouble walking, but most people won't notice it. Her face didn't need surgery since the fractures healed within millimeters of their original positions. The brain is the last thing to heal, and she is a different person than she used to be, most people who didn't know her before won't notice. She can't yet hold a job or go to college. If she had been wearing a helmet it's almost certain that she "only" would have to deal with the punctured lung and a few broken bones. Her not wearing a helment not only derailed her life, but it caused major problems in the lives of everyone around her. She has 250k in medical bills and the legal minumum on liability insurance here is 25k.

2. I snowboard regularly, I've seen people without helmets die on the groomed trails. I've hit my head a few times on logs that I really wouldn't want to be running into w/o a helmet. I've never seen someone who was wearing a helmet permanently disabled by an accident.

I used to think that if you didn't want to wear a helmet it was nobody's business but your own. But when one of those cars hits you, somebody's going to pay for those hundreds of thousands in medical bills, so if you don't wear a helmet please file a DNR ahead of time.

On a "lighter" note, I tend to agree that as a society we should focus on the most dangerous things first. Right now I have a feeling that's the intersection of driving and cell phones. We can probably save the most lives by focusing on driving safety.
Just yesterday I used http://epub2mobi.com/ to convert a public domain ePub file to MOBI, then sent that to my Kindle's email address. It was delivered wirelessly to my Kindle. Are you sure this hasn't changed? Or is epub2mobi doing something to circumvent this?

I hope Samsung will succeed in knocking out these patents. They indeed shouldn't have been granted to begin with. Hopefully more knockouts will follow (not just for Apple, but for anyone who abused the patent system by using the "on the computer" trick).
I initially thought as you do: cheaper ebooks cannibalize the more expensive. But remember books are competing with social networking, tv, radio, iphone games, console games, computer games, the outdoors, friends, pot, bars, etc. While a controlled study would be interesting, I bet books can steal some time share.
They are a rather big and rabid group on Germany.

Another argument by them: sure, having your skull split open when falling and hitting the head on the pavement is bad, but it's really bad when you're falling and instead of a clean hit, your neck is subjected to particularly strong rotational forces due to the helmet enlarging your head, thus moving the point of impact outwards.

They are a nasty bunch.
"Bad things only happen to other people. I would never crash my bike," is the idea, I think.

Statistically correct, I guess, but I'm a pessimist so wear a helmet anyway.
Launch of My New Web App, Imgur For Videos – Feedback Wanted
Hi All,

For the past couple of months I've been developing a web application to freely and instantly share videos without the need for an account. Basically imgur for videos. I've finally got the working build online and you can check it out here at http://quickvid.org. So if you ever just need to send a quick video to a friend and don't want to deal with signing into YouTube or creating an account, check it out.

Please, if you find any issues report them to me via the feedback page.

Comments, suggestions, feedback, welcome!
The usual control is "number of accidents per person-hour". It's really irresponsible to give data without that context.

I don't glean the same meaning you do. To be clear, you seem to be interpreting that statement as:

number of pedestrians injured = 1.4 × number of cyclists injured

while it reads to me as:

chance of injury while walking = 1.4 × chance of injury while cycling

which invalidates your point.
Plus, people look totally different mirrored from left to right. Can you imagine Marilyn Monroe's famous beauty mark or Leonard Nimoy's arched eyebrow on the wrong side?
Seems like there are lots of huge implicit qualifiers for this advice (I disagree with it pretty much completely, but this stuck out to me): The writer is in a country with one of the best road systems around, in a college town, in a town with lots of people that bike.

This is terrible terrible advice for any place that doesn't fit that criteria, and might as well be bad advice in the town that DOES fit this criteria.
Unfortunately, a lot of tweets include links to non-Twitter sites, which would not be included in freebie data. Will be confusing and/or disappointing for users, putting them behind a glass wall of look-but-dont-read.
> Slide-to-unlock was probably a pretty important, cool idea for whoever first invented it

You mean whoever invented the sliding lock? It is indeed obvious in retrospect, but was probably a breakthrough when it was invented (that is ages ago).

Such kind of patents are coming very close to patenting a wheel.
We're all missing the most important point here:

>> Bike helmets discourage cycling.

Yes! We should require all CAR drivers to wear helmets. Imagine how less likely drivers are to engage in road rage when they're wearing dorky helmets, not to mention safety on the road.

It could be that bare headed cyclists get noticed more? Where I live has mandatory helmet laws, so a helmeted cyclist is normal. If I see a bare headed cyclist, it strikes me as an unusual thing to see, and my attention is automatically drawn to him, and I will then carefully pass. If all cyclists were bare headed, maybe they wouldn't get noticed as much and the passing distance might reduce?
If it's true (there are others here who say it's disputed), I would bet it is more because the driver trusts the cyclist more. The more the cyclist looks like she is a competent, experienced cyclist, the less you worry she will swerve toward you suddenly, fall over, or do some other random thing. The less you worry about that, the closer you feel you can get.
again, you're conflating "marketing" with "coverage for hitting the lottery".

Can you please fix the title of the story? "Android Fake ID bug exposes smartphones and tablets"
No, Apple's lawyers are just trying to make it sound more concrete than Samsung's lawyers are trying to make it sound abstract. The key difference is complexity has no bearing on patentability, but abstractness does.

To be fair, the claims do require all those elements, so it really is narrower than "moving an image to unlock a device". You could imagine a number of implementations of the latter that would not be covered by the claims.
Only 100 km down, the gravitational acceleration would not be reduced by very much. Assuming the Earth is spherical and has uniform density, the probe would only be below ~3% of the mass and would be less than 2% closer in distance. So the acceleration felt by the probe would only vary by a few percent.
I've made that argument, but I feel compelled to point out that the vast majority of stacking/mandatory sentencing provisions apply to violent crimes, and exist specifically to deter violence and the use of weapons in commission of crimes, as well as to deter drug crimes (which is not to say that this deterrent effect works in practice - I don't think it does, much).

I'd be happy to discuss this but we need to refer to some better source than Russia Today, whose journalistic standards are execrable. Take this quote for example...

The CFAA, said Auernheimer, was written and approved by then-President Ronald Reagan “at a time when he was so senile” that he thought Hollywood’s interpretation of compute hackers was an accurate portrayal.

Reagan signed the CFAA, but the idea that he wrote it is ludicrous. Then again, Weev loves to troll.

I never understood why adults in the US wear a helmet when they bike (I'm from Holland, no one does that) but now that I've been cycling in LA for a while… I understand. The roads are not built for bicyclists (this "bike map" exemplifies the issue: http://cl.ly/image/1L3E2H063l1u) and drivers are simply not aware. I dutifully wear the helmet here, while my Dutch friends laugh at me.
> If someone's answer to "it is cold in here" is to put a lighter under the thermometer then the problem isn't the thermometer, right? It is the people who are confusing indicators from goals. And that is a culture thing.

But you're not using indicators to do some kind of science, you're trying to use them to make decisions about who gets fired and who gets a raise.

If you're a self-interested human being, you're going to do whatever you can to make sure the indicator points to "give me a raise" not "throw my ass on the street." If the indicator is not a perfect measure of job performance, then you're going to let job performance slide to maximize the indicator.

I am not too sure about all of this. I like the idea of some sort of format for specifying when long-running potentially blocking function calls might end, but creating an entire external package for that purpose feels to me a bit architecture-astronaut-like.

I did think it seemed nice as a pattern, but not as a library... then I got to the idea of a black box for context values. That really concerns me. If a function and a function called by that function both depend on some sort of parameter, why not just specify it as an argument like everything else? If it were somehow possible to only have request handling related functions for a specific application require a context value, that would make sense, but requiring every function called in the process of handling a request to have a ctx value as its first parameter? That seems dangerously infectious, and like using a rake to scratch an itch.

I'll have to wait and see how libraries implement this in practice, but I hope most libraries will continue to just follow the simple, elegant route - if a function may block, document it, and let the caller handle putting it in a goroutine, instead of creating yet more boilerplate.
Start paying for archiving then. :)
It's hard to tell from the abstract alone...

9.2 (95% CI = 7.5–11.3) for pedestrians, 6.4 (95% CI = 4.7–8.8) for un-helmeted cyclists

but to me, it looks like the number is

chance of traumatic brain injury as a pedestrian in an accident = 1.4 x the change of traumatic brain injury as a un-helmeted cyclist in an accident.

This seems to not at all take into account the probability of getting into the accident in the first place, which really makes the argument pretty moot.
For the past couple months, I've thought about John Gruber's stance against helmets. After thinking it over, I'm inclined to believe it matters what type of biking you're doing. Your helmet usage should vary if you're riding in the Tour de France or taking a NiceRide bike (rent by hour deal) around town. Ditto for riding in an area that very bicycle conscious (bike lanes, many bikers) vs not (busy street, curbed, etc).

If you're just beginning cycling, please use roads that are bicycle friendly. Use a road with a wide shoulder or a bike lane and slow traffic. Don't use the busiest curbed downtown street.

I speak as a severe traumatic brain injury survivor. I don't take any unnecessary risk, explicitly to avoid the chance of re-injury. Growing up around helmets as the son of two ski patrollers, wearing a helmet is a part of life. It does not inhibit my riding and while drivers might be less careful around me, I won't take that risk.

> Children and toddlers on foot are far more likely to receive traumatic brain injuries than cyclists

A traumatic brain injury is, at best, a severe concussion[1] and worst case can result in death or a coma that lasts for months. I would just like to make that clear.

I find people's (especially Indian's) puzzled reaction to news about flipkart's funding puzzling. Flipkart has altered the online buying habits of urban Indians significantly. I would be surprised to meet an urban Indian today who has not heard about flipkart. By urban I mean the tier 2-3 cities as well. So is it just the fact that the current revenue numbers do not add up that makes it puzzling to some (most??) ? If I was an investor, I'd bet on flipkart, solely based on watching the change in spending habits of the urban Indians over the last 5 years. Instead on narrowly focusing on the online business if you take a broad look at the way things are changing the tier 2/3 cities in India you'll understand the investor optimism. You mentioned:

> Unlike USA, India has not yet figured out how to build proper usable roads,
> the cities are not planned and India does not have a proper addressing
> system. Government regulations have further made life difficult for courier
> companies. All this has resulted into cities and towns where traveling over
> few kms is very expensive and time consuming as a result small shops
> catering to need of local communities have sprung up like mushrooms.

...but like almost any other success story in India, flipkart has become a recognizable brand despite this !! ...isn't that reason enough to undestand why the investors feel like this is going to be worth it ?
I do! I've been wanting to go to Biarritz and master code for a long time, but wait --- what about my friend who speaks English only... is the course in English or French?
If I understand correctly, your counter-argument is that this statistic is has no bearing because they fail to divide the total number of Traumatic Brain Injuries by the total number of cyclists, making the comparison of total TBIs for cyclists being 1.4x more than TBIs for pedestrians useless because there are more peds than cyclists.

If that's what you're saying, you didn't read the actual study before posting! In the second paragraph of the abstract for the 2006 french study, they clearly state "The annual incidence and mortality of severe TBI were 6.4 PER 100,000 (95% CI = 4.7–8.8) for un-helmeted cyclists"

The important part being: PER 100,000. Making your counter-argument invalid.

As ridership in a given community increases, everyone's quality of life goes up. In such cases, increased driver awareness and reduced biker isolation increases safety for everyone -- drivers and pedestrians included.

read the paper he quoted (emphasis mine):

"The severe TBI of 1238 patients were described. The annual incidence and mortality of severe TBI were, respectively, 13.7 per 100,000 and 5.3 per 100,000. The fatality rate increased from 20% in childhood to 71% over 75-year-old. Compared to restrained car occupants, the odds ratio for having a severe TBI was 18.1 (95% confidence interval, CI = 12.8–25.5) for un-helmeted motorcyclists, 9.2 (95% CI = 7.5–11.3) for pedestrians, 6.4 (95% CI = 4.7–8.8) for un-helmeted cyclists, 3.9 (95% CI = 3.1–4.8) for unrestrained car occupants and 2.8 (95% CI = 2.2–3.5) for helmeted motorcyclists."

As much as I disagree with his entire premise, he does give the number per million hours travelled right after that statistic.

Cyclist - 0.41
Pedestrian - 0.80
Motor vehicle occupant - 0.46
Motorcyclist - 7.66

This does not mean I agree with his argument at all, and in fact it is pretty flawed logic to not do something that gives you 85-88% less chance of serious brain injury just because other activities may be more dangerous.
Sure. Though many of the things needing reflection would also be props, and if the Secret Service were sufficiently interested in cracking down that mirroring or real cash were the only real options, mirroring would itself be "just a line item" to be compared with the other. Like I said, though, probably not actually practical.

Color correction, on the other hand, might be a practical approach...
It would be sort of cool to implement cryptanalysis tools as APIs using this. Like "submit your data and we'll tell you what it might be". I built some tools in python the first time I was working on the Matasano crypto challenges but Go is a better choice. Would be nice if it was supported.

I think the title is wrong - it should be:

"Why it makes sense to drive wearing a helmet"

Based on:

We can also approach it from the perspective of injuries per million hours from a 1996 Australian study looking at head injury risk before the beginning of any helmet laws:

Risk of head injury per million hours travelled

Cyclist - 0.41
Pedestrian - 0.80
Motor vehicle occupant - 0.46
Motorcyclist - 7.66
"Plus, people look totally different mirrored from left to right."

Less so celebrities, in general, though still the case... But anywhere you could swap in a stunt double you could almost certainly get away with mirroring the person.
