The helmet is no more a hindrance than a seatbelt. If you choose not to wear a helmet so be it, you are an adult. But don't expect me to pay for your medical bills if you have a head injury while cycling and you were not wearing helmet.

I also have to wonder if the increased neck injuries cited go back to when helmets were not designed to skid when impacting the ground.

For what remains: First off, i have not realized any sort of slippery slope i am on. I may not have done the best job in explaining my arguments, but i believe them to be sound. I remarked only on your construction of one.

As for your brother, sorry to hear that. It sounds like the car he was driving should not have been on the streets. In germany we have an institution vested with the power to inspect and verify the safety of a vehicle, and any individual vehicle which does not have an unexpired verification mark from them is illegal to drive in public traffic.

I don't know if you have such a thing in the USA or not, or whether whatever is doing that job is just much too lenient.

I'm most likely alive right now because of a helmet. Long story short, I had a crash that resulted in me whipping the back of my head into the ground. I ended up with a very bad concussion, an iffy memory for a couple of months, and a destroyed helmet. I'll keep wearing a helmet.

This is like saying "Im done wearing a bullet proof vest as it only prevents certain types of gunshot wounds, is uncomfortable to wear and not fashionable."
Bike lights are far more important safety gear than a helmet is.

But not having a helmet attracts more negative attention than not having lights does.

Still no improvements on this front.
It doesn't appear anyone read the Author's linked article about the compression of the helmet and which forces it is designed to prevent. So here is a short snippet :

"If the styrofoam does not compress, it cannot reduce linear acceleration of the brain. The most protection that it can give to the wearer is to prevent focal damage of the skull and prevent minor wounds to the scalp. It is not likely to prevent serious brain injury.

This helmet has split along the ventilation slots, which is common. However, the thickness of the styrofoam has not been compressed.
It most likely gave no more than superficial protection.

Some dissipation of impact force might occur from the action of a helmet breaking, but in most cases this is likely to be small. Helmet standards require the foam to start to compress at a level of force less than that which might be expected to lead to brain injury. While it is known that many helmets do not actually meet the standards to which they are supposed to be accredited (BHRF, 1081), it follows that if the styrofoam does not compress at all, the direct linear force on the helmet was minimal and it's quite possible that the cyclist would not have received any injury if the helmet had not been worn.

> s soon as it breaks, it can't absorb much energy anymore, thus it impacts your head a lot more.

But it has still absorbed the energy that it took to crack the helmet. If the strength of the impact is exactly the same as the strength of the helmet, then the helmet will simply crack, and leave your skull intact. However if you're not wearing the helmet, your head receives the full force of the impact.
Here's a 2013 Australian study: "The effectiveness of helmets in bicycle collisions with motor vehicles: A case–control study": http://www.sciencedirect.com/science/article/pii/S0001457513...

Exactly: conditional on you already being a cyclist, it is much much safer to wear a helmet. Astoundingly, this fallacy accompanies every one of these "I quit helmets (and so should you!)" posts that I have ever read.
But I think you could find a vocal minority (or several) to oppose ANY particular implementation. One of the reason the anti-systemd crowd has such a hard time gaining traction is because the only thing that unites all of them is opposition to systemd. They don't agree on what should be in its place instead -- some want to hold onto sysvinit, some want Upstart (although that's a dead end now), some want OpenRC, some want dmd, some want runit, some want something else or something that doesn't even exist yet.

Well you know what ? I wouldn't be doing this if ads provider didn't abuse my trust and displayed popup ads. I wouldn't be doing this if ads were actually targeted (lol jk). Early ads providers fucked it up for everyone. Not only do I hate the very principle of ads, I go out of my way to avoid them.

As for me, my main reason not to wear a helmet is that it limits my field of vision and an ability to hear (including low frequencies) to such an extent that I feel blindfolded. I cannot tolerate even a hat for the same reason.
I'll say that I do that (define constants to variables/consts/#DEFINE/etc and then use them as arguments), and I do it for exactly the reasons you describe. I also try to make magic numbers as self-explanatory as possible - rather than (say) use the number 84600 I'll write 60 * 60 * 24 for when I want the number of seconds per day.

It's way easier to remember what's going on when you come back a year later, and all but the simplest compilers will be smart enough to bash it down to constant parameters if that's possible.

Yeah, more lines of code, but I think readability trumps terseness (within reason). Some functions just use a bunch of parameters and it's not really the extra line to name the parameter that's causing the issue. Also if you're using an editor that does code folding you could just fold that block away.

> The guy sounds insane. Simple physics indicates that the longer the collision the less force applied will be.

The problem is that helmets are only designed (and tested!) to cover one very specific type of crash. The head smashing into the ground directly and at high speed one. And all it does is turn a potentially very severe injury into a less severe one. It shifts the risk-profile from maybe dying, maybe breaking bones in your head and definitely having a concussion to less risk of dying, less risk of breaking bones and definitely having a concussion.

It doesn't do anything when you get in a low speed crash because the compressive strength of the foam inside helmets is actually very high. Expanded Polystyrene (EPS) is the crushable material inside bicycle helmets. Here you can see that 10psi is a very reasonable number and that 25psi plus isn't unreasonable.

http://www.epsindustry.org/building-construction/compressive...

Let's suppose that 10psi is the number and that you manage to crush a substantial portion of the helmet. Maybe that's 20 square inches. That means it took 200lbs ( 10psi * 20sqin ) of force to do that. If the average head weighs 11lbs it must have experienced something like 18 Gs to make that happen. Sure 18 G is better than 60 G (or whatever if you didn't have a helmet) but it's not as though wearing a helmet turns any crash into something very survivable and with very little consequence.

Anecdotally I went over the handlebars once at 22mph. Another cyclist popped out of stopped traffic (not at a crosswalk) and I had about 10 feet to react. I hit her back tire and knocker her over, but I went over the bars and pivoted around my front wheel right into the ground. Headfirst. I was wearing a helmet and very glad to have been but my helmet only had about a 3" diameter flat spot on the top.

Personally I would have preferred that the foam had only been 5psi (instead of 10psi) and that the crush zone had been larger and it would have slowed things down more. But helmets have to pass a CSPC test and it's a 6 foot drop, which means that it doesn't do much unless it's a very, very bad fall. Personally I thought my fall was pretty horrible and that the helmet should have used up the majority of the crush zone, but while the flat spot was 3" in diameter it was only about 1/4" deep out of the 1" or so of total foam depth.

I get that you understand the simple physics, but as it turns out, real life is substantially more complicated than JUST simple physics most of the time.
"The people who wear helmets are likely more safety-conscious than those who don’t, which makes comparing the two groups very difficult and will make it appear that helmets are more protective than they actually are."

Unless the act of wearing a helmet is part of what reminds you to be more safety-conscious. Bucking my child into the car has the same effect.

BTW the author does mention that study about drivers coming closer to bikers with helmets.
You are assuming the accepted, but unproven wisdom that helmets will prevent more injuries than they cause. Did you read the meta study cited in the article that shows a lack of evidence for such an assumption? Have you read about the standards used to "certify" bike helmets, which don't simulate bike crashes very well?
I rather correlate helmet-wearing cyclists to be the "wilder" bikers - since they know that they'll drive dangerously, they better wear a helmet to (feel to?) reduce the most dangerous consequences.

Or to put it in other words: you are more inclined to buy a helmet if you are know that sooner or later you'll surely need its protection. Or since you have a helmet, you know that you can do things at a (psychologically) acceptable risk that you wouldn't do otherwise (the latter phenomenon is called "risk compensation").

Hopefully you will find that thought comforting as they are scraping your grey matter off the tarmac.
That depends on where you are. I was stopped at 5am one morning cycling across Dublin city (my light died on the way) by the police.
It equally supports the argument that people should wear protective headgear when they're driving or walking, but nobody takes that argument seriously for some reason.

To the extent that our helmet obsession dissuades people from cycling instead of driving, it is on average harmful, because the exercise benefits of cycling outweigh the head-injury risk.
And police doesn't stop and ticket for that?
John -- we should talk. I'll email you. rip
Depends, depends... Fracturing of a flaw requires much less energy than plastic deformation. So it is really a question of whether it deformed first and then cracked, or fractured early. In the latter case, possibly caused by a flaw or very sharp impact, not much energy would be absorbed at all!

Where I live there is a bridge over the river which has a multi-use trail (basically, a shared bike/walk/rollerblade/whatever path) on both sides of it. This trail is separated from the traffic on the bridge by a railing and large girders. The bridge was built to carry rail traffic on the top deck and car traffic below.

On the south end of the bridge, the road and multi-use trails jog eastward and up a slope, while the rail portion of the bridge continues south towards a tunnel. This results in a spot on one of the trails where there are low-hanging girders. If you are walking, these are fine, if you are biking these are very dangerous and cyclists who weren't wearing helmets have been killed by failing to duck. Since the impact was directly to the head, these deaths would have likely been prevented by a helmet. Cyclists who veer too far towards the girders alongside the trail have also been killed, again an impact directly to the head where a helmet would help.
Back when crushable foam helmets first came out, there was just an elastic cover wrapped around a foam helmet. The effect of the helmet impact was that it always broke apart; the helmet cover just kept the pieces together after impact.

Most helmets now have a plastic skin over the foam which provides some structural integrity while the foam is being crushed [1]. But you are correct, the helmet only works because the kinetic energy is being absorbed by a material whose composition (closed cells) will naturally break apart into smaller pieces when enough kinetic energy is applied.

SQL Query Result Model – Tips and Tricks
You really aren't helping your argument any here. Linux containers use resource and namespace isolation via the Linux kernel. When we talk about "bare metal", we're using shorthand to talk about the difference between a type 1 and type 2 hypervisor, where when we talk about a type 1 hypervisor we are referring to an operating system that does the actual virtualisation work directly, and when we talk about a type 2 hypervisor we are referring to something like VirtualBox that runs on top of a host OS as a seperate process itself and which does the virtualisation work.

Linux containers rely on the operating system via cgroups and namespace isolation to do virtualisation. That's bare-metal under ordinary virtualisation terminology.
And that is why the purchase of Oculus was bad idea. Unless we have root on the device and can sideload. Locking tech inside walled gardens is harmful to everyone.
Author should also clarify that they're referring to a very, very specific type of riding—commuter and/or casual biking in good weather (sort of mentions this last part).

The most interesting quasi-claim is buried: helmets protect your head, but cause more damage to your neck. That's an empirical claim that I doubt, but at least it's better than "I don't think I look good in a helmet."

> They aren't needed at all. Semicolons in JS are optional.

So they're not really optional. What they are is necessary and if omitted the engine attempts to put them in automatically. The rules for automatic semicolon insertion are in section 7.9 of the ECMAScript 5 standard (http://www.ecma-international.org/publications/files/ECMA-ST...).

This means you're omitting something that is required by the engine but not necessarily required in the syntax which boils down to you losing control of where semicolons end up possibly making your code do something you did not intend because you either misunderstood the rules of automatic semicolon insertion or there was a bug in the syntax parser being used.
