      There are different types of learners. This is why our (in my opinion) antiquated school system works well for only about 30% of students - linear learners
      Message 42 of 42 , Mar 6, 2005
        There are different types of learners. This is why our (in my opinion)
        antiquated school system works well for only about 30% of students -
        "linear" learners thrive in an absorb and regurgitate environment.

        Personally, I prefer a combination of organizational and hands-on learning.
        In other words, give me an outline, show me how to do it a couple of times,
        then let me at it. If I read it in a book, I may ace the test tomorrow, but
        I'll fail it next month unless I've been applying what I learned.

        Others are more "stream of consciousness" and learn best in story form. Some
        of us learn better alone and others learn better in a group. Some need
        examples on a CD-R or in a help file. Some need a teacher to look over their
        shoulder once in awhile.

        The point is, every one of us has some form of "genius," so I don't place a
        whole lot of value on IQ (and mine isn't 170, but it's high enough that the
        Mensa organization wouldn't laugh at me). The key is to find the way in
        which you learn best, then put your effort into that. Sniping at people is a
        waste of your energy, and they'll more than likely return the fire.

        Well written Rick.
        Often high IQ does not sit well with communication skills. I see it with
        some colleagues.
        I would, of course never assume that to be the case in this instance.

        I personally find most of the O'Reilly Perl books easy reading and my IQ is
        well below 170.
        There are very few reference books that I have used as much as their
        "Learning Perl". It is so easy to read. But we all come at these things from
        different starting points, being an old fashion electronics engineer who
        likes to know what is happening under the hood before accepting new

        In all walks of life there are many ways of achieving the same, effective
        solutions.That is not a failing. Indeed life would be boring without it.
        One only has to recognise when the solution has not been effective like the
        disk-pack cleaner referred to.

        That is a good start. You should definitely keep on doing what you are

        A class with a good teacher will help you learn 10 times (or more)
        faster than reading a book. I recommend you look into taking a class
        or getting a tutor.

        This is nothing new. Most people who specialize in something get paid
        because of their specialized knowledge. In most cases, it is
        financially counter productive to them to give that information away
        for free. Think about it... are you willing to program for me for
        free? Sometimes there are intricacies involved in procedures involving
        specialized skills that a layman would not understand. In fact, it is
        usually difficult to explain these intricasies to a layman at all.

        To a child, an accelarator pedal in a car may seem like a boolean type
        of device; Either it is on or off. To a race car driver, 1mm of
        movement can be the difference between winning or losing. No matter
        how important that 1mm is, a child will never be able to really
        understand the importance of it. In terms of programming, you are
        still a novice and you should be humble enough to realize that there
        are some concepts that you _may_ not comprehend yet.

        Having 20 different ways to do the same thing is considered to be both
        an advantage and disadvantage by programmers. There are programmers
        who think that there should only be one or a relatively few number of
        ways to accomplish something. THe idea is that the fewer the options,
        the more standardized and easier to read code becomes. The other side
        of that arguement is that more options gives programmers more
        flexibility. Perl has always prided itself on the fact that "There is
        more than one way to do it!". If you are looking for a more normalized
        and standardized (aka restrictive or less expressive) language, I
        recommend Python or Java.

        With an IQ that high, it would be hard to doubt your intelligence.
        However, even someone like Einstein would have difficulty doing
        something as simple as riding a motorcycle for the first time. Most
        likely, you have no prior experience or skill sets that you can
        directly apply to programming perl. This is why you find the O'Reilly
        books confusing or vague. Once you gain more experience and knowledge,
        you may find that O'Reilly books may actually lack information and are
        too elementary. How good a book is to a specific reader really depends
        on the reader. It doesn't mean that one reader is more intelligent
        than another. It's just means that books are written for one type of

        > bottom line.. i'm having a blast learning and writing the code for the

        You are right. That is the bottom line. You are having a blast
        _learning_. Most importantly, you are learning by implementing a real
        working program that you obviously care about and that is important to
        you. Just remember that this is version 1. Keep track of all the
        versions you make and compare how different version 10 is to version
        1. With your IQ of 170, you should find that the versions differ

        But wait! Versions? Why should I make versions? How will you keep
        track of versions? And how should I determine when to go to the next

        =) Enjoy the next few years...

        There are 10 types of people in this world. Those who understand
        binary and those who don't.
