  1. Other roadblocks on Why Self-Driving Cars Are Still a Long Way Down the Road · · Score: 1

    There are other fundamental problems with driver-less cars: Illusion of control, exchange of information, and unmodeled conditions

    The illusion of control is why some people are scared to death of flying, but feel confident of getting behind the wheel: even though the stats say that people are safer in an aircraft than on the road, people hate to give up the control. Even if the control is just an illusion (you can do little if a drunk driver slams into your car).

    The exchange of information is crucial to any large-scale automated technology. Right now, you try to infer the intentions of other drivers and account for them. If someone ahead of you turns on their indicator lights, you slow down and give them space (except if you live in a major city, where you speed up to avoid giving up an inch - God, I hate San Diego and LA drivers). If every automated car tries a greedy algorithm, it will be havoc.

    The unmodeled conditions are the outliers that might not occur often, but a human is much better equipped to deal with them. What happens in a storm when some underpass might be flooded? A human would take a look out the window and decide to try a different route from the start. This could come under exchange of information as well - basically an automated system cannot make "judgement calls". It needs accurate information to function.

    Given information, the technology today has enough bandwidth to control an unstable aircraft into a standing position; I think we can handle a car on a road. A basic problem relates to how information is collected and shared - an offline car is limited by having only local information, and little predictive abilities.

    That's the 'noble primitive' myth. It's only a myth.

    I wasn't talking about the idea that people in smaller tribes were inherently more moral people (which is what the noble primitive myth deals with), but that crime is low because of social pressures in small groups (where everyone knows everyone, and it is harder to get away with crime) or for other reasons. My point was that crime rate is smaller in a smaller social group, but more and more people prefer to live in/around cities.

    When people were in small tribes and villages, crime was low. You knew everyone. You needed to work together to survive, and if you committed a crime, you were very likely killed or driven out. However, the rise of cities helped criminals hide among millions of anonymous people.

    The truth is, the internet is almost indispensable now. Security will be addressed, as it has always been addressed, after the fact. People will learn to be careful (just as, you know, you don't walk around in certain neighborhoods in the middle of the night wearing jewelry). The reason the internet has so many problems is because it became too popular too fast. It was an attractive target before anyone thought of the security flaws. But they can and will be addressed - there is no alternative.

    What you should be worried about is the crippling of the internet. Legislators will try to pass laws based on physical-world-analogies (and corporate interests). That is a far bigger problem than crime on the internet. E-crime won't make things unusable, but stupid laws will.

  5. Math is reduced to pre-chewed problems where students are looking for identifiers so they know what formula to use and what values to put where.

    Tell me when this wasn't true? I think you are nostalgic for an era that never was. Mathematics in Engineering has always been about number crunching. Students in engineering have always been taught "mathematics" as if it is a tool to solve a problem, no more and no less. I suggest you read Lockhart's Lament to get a better understanding of what mathematics is like, and how it is taught..

    I went to undergraduate (and graduate) school in Electrical Engineering. You would be shocked at the number of students (even Ph.D. level) who think of complex numbers like vectors (complex numbers are scalars, and form a field). You don't need measure theory to be a good engineer. Real analysis, functional analysis, etc. are never offered in the Engineering department - only in the Mathematics dept.

    Most engineers don't take Mathematics - they take a dumbed-down "here is how you use the math as a tool" version without rigor, proofs, and analysis.This has always been true - and for a good reason. Do you need to understand Hilbert spaces and Banach spaces to design a filter? Not really (it helps to get a deeper understanding, but you don't really need it)..

    And if you think the lack of recognition is what keeps people scared of Linux, then you have no idea what problem you are trying to fix. If you market Android as Linux, and expect people to adopt Linux on the desktop in droves, you are sadly mistaken. They might try it, find it is nothing like their phone/Chromebook, and leave.

    To any sane person it is obvious that the idea is retarded, so why do we keep discussing it?

    Really? The last time I checked, no one got denied tenure for poor teaching. The faculty are there to bring money to the university - if they manage to teach well, that is an added bonus. However, they could be great teachers (I've known a few) who get fired because they didn't bring in hundred-thousand/million dollar grants every year of their assistant professorship.

    While the idea is retarded, you seem to be missing the danger. When the university/faculty see the benefits of doing this, they will do it in a heartbeat.

    If I, as a software developer, cannot read a software patent and understand how it is implemented then the patent has no value . None. Patents are meant to be used by engineers to reproduce the patented mechanism.

    I hate to be on the side of IV, but that is not at all true. The problem is that a patent is (in a way) like a legal document - you assumed the purpose is that any programmer should be able to implement it. The purpose is to defend the intellectual property rights of the patent holder against challenges in a court. It would have all the bits and pieces of the complete algorithm/device description, plus a lot of fluff thrown in that makes it hard to read. I'm not sure if software patents must include pseudo-code (I'm only familiar with electromechanical patents).

    The same is true of many research papers I've read in mathematics. If I want to implement the algorithm quickly, I'd look at a book. A paper (like a patent) is for more than just helping others recreate their work. Just because I know how to program, doesn't mean I would be able to easily implement an algorithm for optimization from a paper on Tychonoff spaces (hint: I threw Tychonoff in there to make a point - I just deal with metric spaces, so the technical jargon would be irrelevant).

  9. Risk vs. Reward on Steve Jobs' First Boss: 'Very Few Companies Would Hire Steve, Even Today' · · Score: 1

    . The basics: Make work fun; weed out the naysayers; celebrate failure, and then learn from it; allow employees to take short naps during the day; and don't shy away from hiring talented people just because they look sloppy or lack college credentials. Bushnell is convinced that there are all sorts of creative and unconventional people out there working at companies today. The problem is that corporate managers don't recognize them. Or when they do, they push them to conform rather than create.

    All good advice that MIGHT work. Or might backfire tremendously. It is the same mentality - no one got fired for choosing IBM/Microsoft/Google.

    If you actually try to apply this principle, I believe it will lead to a loss in productivity in general. Outliers are just that - outliers. Listing a few big-names and saying that these guys made it despite their lack of credentials/oddness shouldn't cloud the fact that for a majority of people with lack of credentials is because they are not competent. That is like saying XYZ was a great researcher despite doing poorly in school, so colleges are losing a lot of talented individuals because they don't give people with C- average full scholarships. Given a limited time to hire or monitor people, it is easier/faster to just weed out people for trivial (or not so trivial) reasons.

    Also, most jobs don't require really talented individuals. If you are just good enough, it suffices. Do you need a superstar in most jobs? No (it won't hurt, but isn't really essential to keeping the door open and the company growing). However, a single jerk who doesn't conform can lead to bad feelings in a group. Yes, you might lose something special they bring. But not doing it would almost certainly lead to problems. Unless you have other jerks who can give as good as they can take. Put them together and you would get a dysfunctional group.

    Nothing for/against Jobs per se (I didn't know him), but it seems like the jerk part doesn't seem to be a problem with many managers and top level executives. A jerk who would drive employees to the brink of exhaustion would be welcome.

    And to be fair the manager/executive is not hired to improve moral - short term gains outweigh employee happiness nowadays. It is easier to motivate employees to work hard by being a scary control freak, than by being a kind and caring person who looks out for you. Especially when times are tough and it isn't easy to get a job. And this mentality filters down - if my boss's boss screams at him, he vents at me.

    The problem is cultural. 2 weeks of vacation is the norm in certain parts of the world - money is seen by many (especially the younger crowd) to be the deciding factor in taking any job. A consumerist mentality only compounds the problem.

    The point is that just about any hobby you have will only make you happy in the short-term

    What? The examples given provide lasting value. Things like watching TV and playing games are generally more limited in scope.

    You're flipping things around. Most any hobby will provide happiness on the short term, but not all will provide happiness in the long term. The idea here is that the ones that provide both short and long term happiness are better than the ones that merely provide for the short term.

    I've known lots of people who played a musical instrument for a few years, and then it just collects dust in the corner. It doesn't provide any long term happiness necessarily.

    If you claim that active hobbies have greater than chances of providing you with long term happiness than passive term hobbies, you might be on to something - because they are active, they can be followed on for many years, instead of at the whim of the source.

    Reading, for example, has provided me with many years of happiness, and I expect it will continue to do so. Is reading any different from watching a TV show? Not really. It is still a passive activity - though I have a greater choice in books (though it is slowly changing, since I am not restricted in watching what passes for entertainment in my part of the world). Now, reading might involve imagination (like a kid who imagines himself as a Knight), but it doesn't have to.

    Lasting happiness is a very strange concept - you are happy doing something now. I doubt I'd get much happiness remembering the violin I played as a kid, or the scuba diving trip I took a few years ago, or the TV show I saw a decade ago.

    The truth is, a person might be great at marketing or sales or design or whatever, but they are forced by the system to do things (like remember passwords) - which they might have no interest/aptitude for - just to access information for their job. Computers have become so common, and everyone is forced to do things that they would rather not. I'm sure there are very smart people in lots of areas who can't do the simplest things with their computers - that doesn't make them lousy at their main job, it just means that the technology is preventing them from doing it.

    The problem is, passwords have become a form of identification - kind of like a social security number. They are more like keys. A bank won't agree to give me money if I just show up without picture identification that matches my account details. The password => person is flawed, because that is simply not true. That would be like someone showing up to your bank with your house key and claiming that they now have access to everything you own.

    The only reason we are less herd-like (and we still are very herd like in our thinking - just look at how certain topics are still taboo) is that our survival doesn't directly depend on acceptance by those around us. Sure, I might not have a job if I'm a douche-bag, but chances are I can still find a way to survive. On the other hand, getting kicked out of a prehistoric tribe meant you would pretty much have to hunt alone (assuming you ran away from the tribe before they butchered you), and you wouldn't survive for long.

    Also, the reaction to alcohol varies by culture. You have this idea that people lose inhibition when they drink, but in some cultures they become more harmonious (less likely to cause trouble or act out - see here).

    I'd say that the leaps and bounds in infrastructure and tech have allowed us to lead more solitary lives, which also means we have less inclination to conform.

If a regulator were to drive the car, they would see any taping over. They would notice that the interiors have been stripped down. And they should put a stop to it. Basically, they should be given a car by the manufacturers, and the regulator should hire someone to do the road tests.
