    OH HOW I ENVY AMERICAN STUDENTS

    Since it's coming up to the start of a new academic year I thought I'd take this opportunity to explain how lucky you Americans are to have a fraternity system.

    English Universities are so dull by comparison. Like most students in England I had to rent private accommodation for my second and third years, but it never occurred to us to build a whole culture around collectively renting a rather dilapidated house in Clapham. It wasn't even single sex accommodation, so we couldn't engage in the fun and games of para-homosexual activities - Girls just don't have the same grip on your loyalties as your Greek brothers ;-). And while cliques certainly form in English Universities, the are all much too boring to come up with the idea of hazing. I fondly recall diving off a weir and almost drowning when I was 12 because everyone said I was chicken. If only it had been possible for me to gain respect in later life through similar tests, and if these tests could have been combined with pseudo Masonic rituals culminating in the awarding of a little badge, then that truly would have made my time at University worthwhile. And while I still have friends from University, these friendships seem so hollow compared to bonds of fraternal brotherhood since they are not based on solemn vows of fellowship, mutual sacrifice, group solidarity and owning the same poxy little badge.

    Then there's sheer joy alcohol seems to bring fraternity members.. By the time I went to university the delights of getting dangerously drunk at parties had started to seem mundane. But to American students in fraternities, the bravado of excessive alcohol consumption is a an exciting new and illicit game where you can prove yourself worthy to all your male friends and simultaneously circumvent college alcohol policy - thereby proving what a rebel you are too. Gosh. I am also rather fond of the references to ancient Greece. It reeks of a history far nobler and grander than anything a British University can instil its students with, and the wearing of togas must make it seem as authentic as a ploughman's lunch. I think what I am trying to say is that Fraternities give young Americans the chance to grow up in their own time, and that it is regrettable that no similar opportunity is afforded to European Students. In particular, I find it sad that even some American students forego the opportunity to wear togas and claim to be Greek. Really this should be mandatory, so every graduate will be secure in the knowledge that they have gained something much more valuable than a degree from an American University - a little badge with some Greek letters on it.

    Although I am not American, I admire the system so much that I would dearly love to become an honorary member of a fraternity. I have set my heart on becoming an alumni of Theta Omicron Sigma Sigma Epsilon Ro Sigma. I do so hope this is possible.

I deal a lot with statistics in the computer world, and we are contracted often by ad agencies for information in regards to the preferences of computer users. One assignment was dealing with the operating systems and their user's lifestyle and preferences. The results we came up with were interesting and shocking. Here are some memorable tidbits.

    Windows users

    87% of Windows users are employed (3% on welfare)

    40% hold a university level degree

    43% in a heterosexual relationship

    5% are in a homosexual relationship

    3% have a serious mental disorder

    32% of linux users are employed (15% are on welfare)

    35% hold a university degree

    4% are in a heterosexual relationship

    56% have a serious mental disorder

    Thus we have concluded that effective ads related to linux should try and target the mentally disturbed, homosexuals, and the unemployed.

    I remember thinking how naughty it was for me to pee outside with an erection -- this was
    a few months after my father had told me not to show my penis outside of the house. I
    remember my grandmother laughing at the sight of my brother fiddling with his little
    erection and asking him if it tickled. I remember my father showing me how he played
    with his penis, and I remember thinking that my penis would never get that big and hairy.
    I also remember my mother explaining to me and my brother how women masturbated.
    That was interesting -- our questions about pubic hair and why it existed led to Mom and
    Dad both shaving their pubic hair completely off. Mom used bikini wax and Dad used a
    razor, which meant that Mom was smooth and clean while Dad was slightly bumpy all
    the time until Mom convinced him to use bikini wax as well. That reminds me that when
    I first got my pubic hair growth, I refused to shave it even though neither Mom or Dad
    had even suggested such a thing. I guess I thought they would demand that I shave too,
    I1m not sure why I thought that. I think I was about 14 when that happened.

    As far as seeing my parents have sex goes, we didn1t see too much. We did see them
    perform oral sex on each other quite a few times, and we watched them make love a
    couple of times. Mostly our observations were confined to watching Mom and Dad do a
    little heavy petting. Then they would head to their bedroom and since my brother and I
    thought that sex was natural and normal, we didn1t really have any desire to follow them
    to the bedroom and watch. We knew what they were doing.

    Which leads me to what my brother and I ended up doing. For years my brother and I had
    been naked together, sometimes with erections, and thought nothing of it. Of course, I
    was five years older than him, too. About the time I was nine and he was four, our play
    grew to be more sexual than usual. We would touch each other1s penises instead of our
    own. We would lay next to each other in a sort-of 69 position and just caress each other1s
    penises and scrotums. It didn1t occur to use for some time that we could suck each other,
    but eventually we did figure it out. At first we would kiss and lick each other and
    gradually we progressed to actual sucking. We had no idea what we were doing and
    would treat each other1s penises like lollipops or popsicles. It felt good, anyway. We
    would do this at night most of the time -- he would come lie in my bed and we would
    touch each other until one of us got sleepy, usually him. Then he would go to bed and I
    would fondle myself until I went to sleep too.

    I taught my brother about the thrill of peeing outside. We were breaking two rules: the
    potty-training rule and the no-public-exposure rule. We would walk several blocks away
    from our house to a field next to the school. From there we'd cut across the field and go
    into the edge of the state park there. Once we were within the dense woods, we'd take off
    our clothes and pee in one of our hidden spots. We never got caught. Eventually, as you
    can guess, this led to sex between the two of us in the woods. Only during warm weather.

    As far as getting caught goes, it only happened a few times. Our parents found us in
    various stages of sexual activity when we were younger, like when I was 13 and he was
    8, around those ages we weren't quite clever enough to not get caught. One or both of
    them would find us either getting undressed, playing with each other, sucking, or getting
    dressed after we were done. Most of the time they just smiled and walked away. If one
    parent caught us and the other parent was home, the first one would leave us alone and in
    a few minutes the other one would show up, smiling and all that. I know they were
    excited by the idea of it because many times after they caught us, they'd end up in their
    own bedroom. They never had sex in front of us right after they caught us having sex
    play, I'm not sure why. ummm ... my dad caught us several times and so did my mom.
    Actually mom more than dad because she was home more.

    It was no big deal to them. Especially since we'd all bathe together and everything. I just
    remembered a time when me, my brother and my dad were in the shower together and
    one after another we all got erections. When we were all rock solid hard, my little brother
    and I started playing with ourselves and then Dad started masturbating too. When we
    started playing with each other, Dad kind of gasped and turned to the wall and came all
    over the wall. That must have been a great orgasm for him though at the time I didn't
    know what an orgasm felt like, though I knew what they were. Anyway, a couple of
    times after that, especially when Mom wasn't in the house, when Dad caught us in a 69 or
    whatever, he'd just take out his penis and masturbate while watching us. For some reason
    we never thought to include him and he never asked. Frankly I'm glad because that could
    have been kind of fucked up.

    Anyway, as we got older we got better about our privacy. About the time I first started
    cumming was when Mom and Dad quit snooping around, walking in to our rooms
    without knocking, etc. Also my brother and I spent more time in the woods or in the
    basement where we were not so easily caught. I think I was about 13 or 14 when I first
    came while my brother was sucking my penis. He wasn't surprised by it but he didn't like
    the taste (and neither did I at the time). In the evenings (we still shared a room) we'd go
    to bed, both nude or partially clothed, turn out the lights, and if one of us was horny he'd
    just climb into the other one's bed and try to get things going. As I got older I got more
    irritated with my brother's attention, especially when I started high school and had to get
    up an hour earlier. I never really got eight hours of sleep after 9th grade. :) But, to make a
    long story short, we continued with our sex play all throughout my high school years. We
    learned about rimming and anal sex through pornography and some of our parents' more
    graphic books, and we tried those too. The first time my brother came during sex with
    me, he was 12 and I was 16 going on 17. He was fucking my ass with his little penis
    while I masturbated, and suddenly he clenched my ribs and spurted inside of me. It felt
    really good and I did it to him later that week. About that time our sex started happening
    more often because he was wanting to cum more often and basically, I liked to eat his
    cum and I liked getting fucked by him.

    When I went off to college I missed my family terribly though I did have plenty of great
    gay (and straight) sex that first year. :) I came back for Christmas holidays and it was like
    being in a new house. My brother didn't even react to the sight of my hard penis anymore,
    where before he would eagerly suck it or at least rub me a little. Now he just played the
    whole thing off. My dad and mom were just as nutty as ever, though. In fact, I was
    actually kind of embarrassed when I walked in on my mom giving my dad head in the
    bathtub. Things change.

    OK, fast forward to now. I'm 20, about to turn 21 and my brother is 16. Summer break
    just started here at school and I have my own apartment and job. I have two roommates,
    one is a straight man and one is a gay man, and neither of them are interested in me. :)
    My brother came to visit at the beginning of the summer break and while he was here he
    slept in my giant king size bed with me. The first night he was here, we both stripped
    nude and got into bed. I expected him to at least keep his underwear on but he didn't.
    Almost as soon as we were in, he snuggled up behind me and I felt his hardening penis
    press against my buttocks. I reached back and felt him, then turned around, slid down
    under the covers and sucked him for a long while. In the middle of that he rolled onto his
    back and I got on top of him, still sucking his penis, so he could rim me. It felt so fucking
    good, I was about to cum already. When his cock and my ass were good and wet I
    squatted over his crotch and guided his penis into me. Then I slowly sat forward and
    kissed him while he made love to me. We stayed up for another three hours mostly
    fooling around but also talking. The next morning it was again as if nothing had
    happened. But the next night we did it all over again. It went on that way for the whole
    week he was here. The sex was great but I am not sure if my little brother is the same as
    he used to be in terms of just being open and accepting about gay sex.

    I almost forgot to tell you about my other childhood sexual experiences. Aside from my
    brother, I fooled around with a few friends in middle school -- mostly mutual
    masturbation and stuff like that. That's about it, too. I guess I confined all my
    experimentation to my brother.

    Oh yeah, I'm 20 years old, in the middle of my college education, middle class, with two
    loving parents and one younger brother, but you knew that already. :) I'm white, live in
    the MidWest and I'm basically an agnostic, so is my whole family. That's all.

    Slashdot: News for Nerds? Or Propaganda for the Impressionable?

    Day in and day out, Slashdot sings the praises of "open source" software. New readers of the site must be a little puzzled to find items like "GPL Violation discovered" and "Open Source Guru Speaks" listed on the main page alongside the "straight" science and technology news. Unfortunately, few people really know what Open Source stands for. Perhaps Richard Means Stallman, one of the founders of the movement, can elucidate.

    "[The GNU goal was] to be able to use a computer without using any proprietary software," declaims RMS. "Because that way, you can lead a better life." Of course, the only way to get rid of proprietary software is to destroy the software companies that produce it. One way this is accomplished is by putting software that would normally be public domain under a license RMS himself created, called the "General Public License," or "GPL." Simply put, this license allows code to be reused-- unless the final product is distributed without its source code, as a proprietary product must be.

    Software is a commodity, and people will often take the cheapest product, even if they have to spend inordinate amounts of time struggling with poor documentation and clumsy user interfaces. "One of the best things I could do with my life is: find a gigantic pile of proprietary software that was a trade secret, and start handing out copies on a street corner so it wouldn't be a trade secret any more," enthuses RMS. "Perhaps that would be a much more efficient way for me to give people new free software than actually writing it myself."

    It's time to stop the doubletalk and start thinking about the real meaning of intellectual property. By some measures, intellectual property is the main export of the developed countries of the world. Artists, actors, and musicians make a living off the intellectual property they produce. Programmers and engineers create designs to be sold. And journalists and writers depend on intellectual property. Ironically, the only jobs not deeply tied to intellectual property are the jobs many slashdot readers affect to despise, like service workers, menial laborers, and administrators. If slashdot readers can't stomach Scott McNealy, maybe they would prefer to work with Ronald McDonald. From the other side of the fast food counter.

    Not everyone enjoys working at a menial job in the day, simply in order to slave away at poorly organized programming projects. Not everyone enjoys being told that he has the "freedom" to work, without pay, for a small clique of free software partisans. It is one thing to oppose microsoft's monopoly on the desktop, and the RIAA's slow strangulation of fair use rights. It is quite another to embrace a whole economic and political ideology that centers around the exploitation of childlike programming savants.
