  2. Incentive Structures on Employee Stock Options? · · Score: 5, Interesting

    Programmers are a lot like lawyers, value-wise. Like lawyers, the value of programmers is, or traditionally has been, their creativity and intellect. Better tools have reduced the value of that personal asset in programmers, but not eliminated it.

    It is notably different from most engineering in that the products do not require large capital to distribute, once the creativity is complete.

    In this manner, I have often wondered if programmers would work better in limited liability partnerships rather than corporations. A small group of programmers who produce on contract to corporations would be, if well organized, very valuable.

    The corporate structure lends itself to growth in traditional economy, whereas a larger programming companies have, in my limited experience, not been efficient. There are exceptions, like Electronic Arts, I think.

    But the hierarchical view of corporations, looking down upon employees, is flawed in the programming world because the direction of the company is often better felt by the programmers themselves, and management has often had a terrible disconnect from the technical reality, and a tendency to dictate where they should listen. Good management isn't necessarily this way, but many people cling to this management style.

    In a partnership, the partners would be responsible for bringing in clients, the design, the programming, and the effective reuse of code. In a corporation, they are typically responsible only for the programming. I believe savvy programmers would be much better at selecting appropriate clients and choosing the direction of the code. I believe, when it comes to the effective reuse of code, a partnership would have better structures adopted to accommodate it.

    This sort of delegation among partners has been very effective, in my opinion, in lawyer partnerships. I believe the effectiveness could translate into programmer partnerships. Mind you, moving programmers into management positions in companies may have the same effect, but I think the hierarchial structure inherently causes problems. The distinguishing feature being that in a partnership, management would also be programmers, and vise versa. There wouldn't just be a "delegation to programmers" by management, so to speak.

    Just food for thought.

    Downloading is protected under, at least, Part VIII of the Copyright Act, which is "private copying". From it, you can infer that you can download as much music as you like. Private copying arose from the days of tape cassettes; it gives musical copyright holders the right to levy blank audio media as a form of remuneration for private copying. It only covers music. Movies and software downloads can violate copyright without permission.

    Uploading was upheld on an evidentiary matter. There was insufficient evidence to show that the user intended to upload the music, but rather uploading seemed to be a side-effect of using the peer to peer software, according to the judge.

    To be clear, the judge did not "legalize" uploading. He simply stated that there was insufficient evidence to show that the user intended to upload, in other words, he never had the mental culpability (ie. mens rea) to have infringed the copyright.

    That article doesn't say how many small vehicles are on the road, versus larger ones. As a result, there are no conclusions about accident avoidance; if most crashes involve SUV's, for example, but the vast majority of people drive small vehicles, even though there's only a small chance of substantial injury in a SUV, it would still be much safer to drive a small vehicle because it's less likely to be involved in an accident. The converse is true; if there are far more SUV's on the road, and fewer accidents involve SUV's, then they are absolutely safer.

    There are actually a number of statistical problems with the conclusions of this article. It ignores many, many relevant points. How many small cars versus large SUV's are on the road. How many types of small cars are there, and how are they distributed? How many types of SUVs, and how are they distributed? If there are 100 types of SUVs, they may be MUCH less safe in spite of this conclusion, if there are also only 20 small car types being measured: None of the SUV's would make it into the top 20, although in aggregate, they would be the least safe. I don't mean to say that this is the case. I doubt it is. Nevertheless, it does put doubt upon the conclusions.

    Most importantly, however, this article does not reflect general vehicle safety, only the safety of vehicles that have been in crashes with other vehicles (from my brief skim of it). Perhaps more SUV's are in more crashes in general, or more accidents involving roll-overs that do not involve other vehicles. Crash safety is not overall safety.

    Any conclusion would be speculative, but I must suggest that this article is not very indicative of an SUV's actual safety on the road, only its safety when hitting other vehicles.

    Everything else aside, the vehicle is LESS SAFE to the occupants because it's lighter. I suppose that makes it more safe to the people in the other vehicle. When two masses hit, the lighter mass undergoes a greater change in velocity. This will be "felt" by the occupants, which means they're going to be injured easier.

    Don't confuse traffic safety with head-on collisions. The latter is a relatively very small, albeit sensational, component of traffic safety. Breaking distance, vehicle responsiveness, and accident avoidance, on the other hand, are fundamental components to traffic safety, especially in emergency situations. They generally increase the occupants safety, including the rare cases of head-on collisions. I'm not saying the Smart Car is less safe in head-on collisions; it may or may not be. But it is certainly generally more safe.

    [The crumple zone is there so] the occupants of the car do not feel the full "smack" of going from 60mph to 0mph in a hundredth of a second. Decelerating that quickly will severely injure a person. Airbags can help, but regular cars have those as well. Advantage larger car.

    Bear in mind that "crumple zones" are an industry invention that makes a fender bender a multi-thousand dollar affair, proceeds to said industry. They increase the distance of sudden deceleration by up to two feet. A Smart Car car, on the other hand, has half the weight of the average vehicle, meaning that its capacity to decelerate prior to the accident is increased dramatically, not including its greater capacity for avoidance. Your capacity to safely stop suddenly is less important if you can avoid or break more efficiently.

    Lighter is safer. Ask any traffic engineer.

    Reduce braking distance
    Having done any research into vehicle safety would reveal this (though, admittedly, I didn't mention it, presuming that anyone with a iota of physics background would take this for granted): Even though you can't reduce reaction time, the next most important factor in traffic safety is braking distance, which is directly proportional to mass. You stop faster with less weight.

    Accident avoidance
    After that, I understand the next most important safety factor is avoidance, a function of lateral traction, proportional to tire width, gumminess, and closeness of the axels, and inversely proportional to mass. The less your mass, the more lateral traction. If you can avoid or stop before the accident, the odds of a detrimental accident decrease.

    Functions of time
    So, as you say, "it's not the speed that kills you, it's the sudden stop", the Smart Car simply slows faster prior to the sudden stop, so when that sudden stop happens, you're going much slower. Safety as a human function is directly proportional to the time of the stages in an accident: realization, reaction, braking or avoidance, and impact. More effective braking and avoidance make your time more useful.

    Crumple zones
    Albeit, in a smaller vehicle, there is a small but substantial increase in the potentially vital impact component. However, if you put a 730kg (1600lb) vehicle (the Smart car) against an average vehicle sized sedan at 1500kg (3300lb), the sedan will simply stop further away from the point where the driver realized and acted on an emergency situation. That distance translates into not just fewer accidents, but lower speed at the point of impact, hence less force involved in the impact, and hence fewer and less severe injuries.

    Emperical questions
    To measure the safety, you have to look at the merits of the differences between this vehicle and others. These merits are not necessarily obvious, involving at least:
    * How do most accidents happen?
    * How do most injuries happen? I believe the vast majority of accidents are rear-enders, which can be substantially reduced with better breaking distance and avoidance.
    * How many vehicle accidents are related to inadequate lateral traction?
    * Does the increase in avoidance and braking capacity result in fewer accidents?
    * Lower the cost insurance?
    * Lower fatalities? Of the owners? Of SUV drivers?
    * Result in fewer fender-benders?
    * How many are head-on collisions? (The only case where this vehicle would seem to be substantially less safe, isn't it? This is the case where momentum clashes and your body velocity goes from +X to -X)

    Geneology of Driving
    These are sort of anecdotal arguments that I've bought into: Humans aren't designed to acquire and react to information at speeds provided for by vehicles, though we have compensated very well. Two factors remain very good at making drivers more comfortable, and hence more adequate: visibility and fit. The more visiblity you have, the less compensation your brain has to do to make up for blind spots. The better you feel you have control of the vehicle, ie. how it 'fits' you, the less time your brain spend compensating for unresponsive or poorly responsive mechanics. However, a large car can have both of these. There is also a question of security; insecure drivers, ie. those in a smart car who are uncomfortable being surrounded by SUV's, may react poorly (or perhaps drive more cautiously; who's to say).

    I hope that clarifies the reality and reveals to you how physics of lighter vehicles can, and typically emperically does, make them inherently safer. Bear in mind, the old Volvo tank model of safety has its merits, too. But the Smart Car is not a death trap, unlike nearly all SUV's (save the Subaru Forrester, in the USA, iirc).

There is no substitute for a lack of mass when your vehicle becomes a ball of plastic and metal momentum; the more weight, the more force is required to curb that momentum, so to speak.

    Lateral weakness = myth
    From the side, the risk of being "T-boned", or laterally impaled, is highly overrated. The solid beam connecting the rear wheels, the axle, and the similarly reinforced front wheels, in such close proximity pretty much insure that if you are hit, unless it's a motorcycle, two of your strongest and most reinforced points of impact (the tires) are involved in the crash. Furthermore, there is a metal cage surrounding you that can easily withstand substantial impact.

    Run-over = myth
    The risk that it will be "run over" are also highly overrated. If a big vehicle hits a smart car, it becomes a wedge, pushing the larger vehicle into the air so that the larger vehicle can dissipate its energy on other things, like concrete, pavement and telephone poles.
