    You can never say definitively which of the many radiation exposures caused an individual death or illness. When we say that deaths are directly attributable to a particular cause, we're referring to deaths in aggregate. For example, you might have 3,400 cancer deaths per million people in people who have had a particular medical procedure, where there are statistically about 3,219 deaths among the general population (maybe excluding people who have had that procedure, depending on your point of view), so 181 people died because of the procedure. I'm oversimplifying here, of course, but that's the basic idea.

    You aren't taking into account that it makes no sense to drive a car at its limit for long. No car, economy or high performance can handle the rigors of being close to its maximum for long.

    Actually, in terms of car life, vehicles that are mostly driven at 65-80 MPH on the highway last much longer than vehicles that are mostly driven in town, with fewer breakdowns and other problems. What causes the most damage to vehicles is in-town driving at slower speeds. Between the steering, the constant starting and stopping, etc., you have a perfect recipe for wearing cars out.

    Ask any race team (especially the non professionals who like to race street cars on the track) and you'll see how often things break when you push a car to its limits.

    To be pedantic, race teams push cars beyond their safe limits. They burn up tires because they're peeling out all the way around every curve. They break struts because they're operating at G forces that are beyond the vehicle's true tolerances. And so on. Yes, the vehicles can handle such abuse for a short period of time, but that doesn't mean they are operating at their limit. They're operating way, way past it, and every minute those cars remain functional is more luck than anything else.

    ...the redneck farmer in the other lane might swerve his 1950's pickup into that chain of cars without a computer to tell the chain of cars it's coming.

    This is why the law should require all cars, including vintage cars, to have a transmitter installed that reports steering wheel position, brake activation, and vehicle location.

    The radiation produced by the scanners is non-ionizing. RF is non-ionizing. It's not an X-ray, or an MRI, or a CT, all of which use ionizing radiation. So you lose points for that one.

    unhindered: when you get a packet, move it on when you can.

    Devil's advocate: it's possible to create a network that complies with these rules that is still unusable for many purposes. Multimedia communication is becoming a more and more important part of the Internet landscape, whether you're talking about AIM A/V, Skype, HTTP live streaming, or whatever. HIgh latency or large variations in latency can kill all of those sorts of uses of the Internet. Sending packets on as soon as you receive them produces just the sorts of high latency with wide variation necessary to ensure that these types of services are infeasible under even light backbone congestion. That's why we have technologies like QoS routing.

    A proper network neutrality law should allow for load balancing (limiting the data rate of heavy users during periods of high congestion to allow room for other people's traffic), QoS (limiting the data rate of bulk traffic to allow for near-isochronous delivery of latency-sensitive traffic), and various other things while preventing limiting throughput based on what server you are connecting to on the other end, preventing companies from charging non-customers for better access to their customers, preventing limits on heavy users during off-peak times, preventing limits on bulk transfers when the bandwidth is not otherwise being used for latency-sensitive traffic, etc.

    Thus, network neutrality is not simple. The reason we won't ever have net neutrality laws is that it is fundamentally so complex that maybe three or four members of Congress can even understand it. And that's actually an optimistic estimate; a more likely estimate is zero members. Heck, I don't even understand all the ramifications of it, and I've been working as a software engineer for more than a decade, including writing some networking software.

    • stored for later examination without the distortion applied

If you can't see it half a mile in advance you are either on an incredibly badly designed road or you cannot fucking see.

    It's not just not seeing the backups. It's the stupid lane changing maniacs trying to force their way through the backups. If every one of those people got text message alerts notifying them of backups, and if every one of those backups were adequately reported by someone calling on a cell phone, many of those accidents would not happen because the people who were in a hurry would find an alternate route around the problem and would miss the backup entirely. When I listen to traffic reports in the San Francisco Bay area, it's almost inevitable that in any backup, there will always be at least one, and often two or three additional accidents in the backup. Backups cause accidents, whether you want to admit it or not. Not fatal accidents, generally speaking, but accidents.

I always stop talking before any exit ramp, and that's as complex as the junctions get. It is not only possible, but easy to drive responsibly while having low-stress phone conversations. Some of us are that sensible, and our rights should not be taken away merely because a few idiots don't know how to drive. Spank the idiots with fines for unsafe driving.

    Drunk drivers also fail to keep the car between the lines, sometimes losing consciousness completely. Drunk driving isn't just about reaction time. When you stop drinking, you are still impaired for a long time. More importantly, when driving under the influence of alcohol, even after that longer reaction time, your judgment---your ability to figure out how best to handle a dangerous situation---is still significantly impaired.

    With a cell phone, that is not the case. When you stop talking and stop listening to the phone, you are no longer impaired. Thus, the argument over cell phone use is entirely about reaction time. Reaction time does not paint a complete picture of driving safety any more than latency alone paints an accurate picture of network performance, and for precisely the same reason. When driving, 99.9% of the time, reaction time is unimportant (at least in the U.S.). If you find that people are constantly pulling out in front of you or are driving dangerously in such a way that you have to react quickly more than once every couple of months, you should move somewhere with drivers who know how to drive.

    By contrast, staying on your side of the road and not veering off into a tree is important almost all the time. Therefore, the probability of an accident due to alcohol impairment is orders of magnitude higher even if the reaction times are otherwise equal.

Far better if they instead pass laws that simply mandate certain types of companies conduct regular security audits by their choice of external auditors, coupled with penalties if those audits find that the companies are not following established industry standards.

    Alternatively, the government could create a standards organization consisting of industry leaders and security researchers to create and maintain appropriate standards if they don't think the existing industry standards are good enough.

    What you are demonstrating is a failure of the education system, and more specifically, a failure of the driver ed curriculum. I drive while talking on the cell phone all the time. I know the road like the back of my hand, and I keep a longer stopping distance to compensate for the extended reaction time. When I see vehicles encroaching on that stopping distance or changing lanes rapidly in front of me or braking, I say "hold on" and I switch my focus fully over to the road until road conditions improve. It really isn't hard at all if you are taught how to handle it. This happens at least once every couple of weeks. Don't tell me that people can't stop talking on the phone, because I do it all the time. If other people don't, it's probably because they are physically holding the phone and don't want to drop it. That's why hands-free laws are almost inarguably a good idea. It frees you from having to take the time to comfortably put down the phone. That's not the same as banning all phone conversations, though.

    The main reason for all the accidents is that driver education classes naively say "don't talk on the phone" and "don't be distracted" instead of properly teaching people how to handle distraction (which is, quite frankly, unavoidable, whether it's talking on a cell phone, yelling at someone on talk radio that you disagree with, or conversing with the person sitting next to you in the car). In short, these sorts of laws don't solve the problem. They make it worse by naively painting distraction as an avoidable situation when it really isn't.

    More people shifting from open federated protocols to the closed world of Facebook is a bad thing. I sincerely hope that it doesn't happen.

    It won't, or at least not for long. Facebook is too fundamentally broken. My account was hacked yesterday, and some d**n bot sent out chat messages to my friends trying to get them to sign up for IQ tests. I didn't feel violated, just annoyed. I kicked the bot with an account block/password reset, and I doubt I'll have problems again for a while.

    The reason for that happening was twofold:

    1. Facebook, to my knowledge, has no system for detecting distributed password guessing on an account and notifying the owner of the account or requiring additional authentication beyond the password in order to make forward progress (e.g. receiving an email at the registered account). Instead, they don't do anything until somebody reports the account as having been hijacked, by which time the attacker has been doing things for who-knows-how-long.
    2. I used my lowest security password because I have about as much trust in Facebook's ability to keep my passwords safe as I do in the TSA to keep my flights safe.

    Why, you might ask, do I consider Facebook to be completely unable to keep passwords safe? Because their entire security model is fundamentally broken, so I don't trust them at all. Here's a quick look of some of the more egregious flaws:

    • Connections are made in-the-clear over HTTP instead of HTTPS. It's unclear if this applies to login credentials or not.
    • Facebook forces you back to the HTTP site even if you connect via HTTPS. Every single solitary link generated programmatically by Facebook is an HTTP link even if you connected via HTTPS. That's a fundamental security screw-up, as it makes the site impossible to use in a secure fashion.
    • Facebook relies on cookies as the sole access tokens instead of using proper browser-based security such as user certificates or HTTP digest authentication. This means that anyone who can sniff a single request now has full access to your account merely by capturing the site cookies and replaying them with a new request.
    • Facebook has no mechanism for requiring additional authentication when a client connects from a previously unknown IP address or IP range.
    • Facebook has no mechanism for preventing keyboard sniffers from obtaining your login credentials.

    The net effect of this is that Facebook is at the very bottom tier as far as my trust tiers go. I do not use any password on that site that I care about, and I treat everything on Facebook as inherently untrustworthy.

    For this reason, I will never use Facebook as my primary email platform. It simply does not have the same trust as email (which itself has a fairly low level of trust because of the ease of spoofing). And I know that most of my friends (even those who are not particularly technically inclined) know this also. So unless Facebook massively improves their security story, they will not supersede email.
