      Half seriously, though, you might think of superconducting chips to eliminate the heating due to the resistance in aluminium/copper wires. But AFAIK you can't build logic circuits entirely out of superconductors. The siliconductors (sic :-) we now use, require current to pass through potential differences (energy gaps in the crystal structure). Power dissipated equals current times potential difference, period. And there are lower limits for the voltage imposed by the semiconductor used.

      Until we get something entirely different, I'm quite happy to put my geekineering effort into the design of better cooling. I'm sure it can be almost as fun as inventing new kinds of logic chips.

      I've been looking into this a lot recently, and there's some pretty (ahem) cool developments on the cpu front recently, with x86 architectures.

      Some people point to the VIA C3-800, but if you have real computing needs, steer clear. It runs comparable to a Celeron 400, which is almost, but not quite adequate for general computing. Instead, check out the old reliable suppliers. The shift to .13u means a lot. Frequencies are so high and chips are so powerful that underclocking has become a real option. A good general target for fanless operation is about 12 watts. You can go higher with good case airflow, or lower if you're dealing with troublesome ambient temperatures.

      Right now, you can take the Intel Tualatin pIII 1.13GHz (28W), cut the bus speed to around 100MHz, cut the voltage down to about 1.1v and be right in the target range. Of course you won't know exactly w/o experimentation on your cpu, but it *should* be doable. If you're worried about losing efficiency to bus speed, remember that you can compensate by running it on one of the PIII DDR chipsets that are now available (upping effective bus speeds to 200MHz) or waiting until February, when Intel says they'll release a similar part themselves. Additionally, the 512k (vs 256k) cache on the pIII-s will offset lower bus speeds. Just check out the specs of the PIII-M LV models at developer.intel.com and ask how they got to those low wattage numbers with the same core. Since the last fanless G4 was 400MHz and claimed (in its wildest fantasies) to be a supercomputer twice as fast as a pIII, a fanless 800MHz pIII is not insignificant.

      Even better, surprise, is AMD. The current mobile palomino runs at 1.1GHz, 1.1v, 25w. This is clearly just an underclock of the current 1.75v desktop XPs. But what it tells you is that the AMD architecture is very open to undervoltage at lower clock speeds.

      Now if you consider AMD's forthcoming die shrink, things really look good. Zdnet.de reported (unsourced) that the Athlon 1.73GHz processor would drop from about 75W to 45W after the changeover. Depending on how far you could drop the voltage, you could be looking at a 1-1.2GHz part running at about 10W! Fanless! Now imagine (a beo..no) 2 of these in a well ventilated case, with an MPX board -- 2GHz of dead silent AMD power! Wooo!

      Alright, I'm calmed down. Back to your original point. It's really a shame about the alternative architectures. Every time I think of venturing into the embedded market, I get brushed off by the 2x price, 1/2x power rule. But since the ARM and PPC don't seem to be generating any economies of scale, at least mainstream processors are progressing fast enough to make cool, cheap and fast a real alternative.

      Also, the decreasing die sizes of new CPUs are detrimental to cooling as well. If shrinking a CPU die decreases cost (can make more CPUs off one wafer than before), but if better cooling equipment is required to build a system with smaller CPU dies, then where is the cost and noise savings?

      Just manufacture CPU dies at larger sizes. Its harder to cool something that is not only thermally hotter, but has a smaller surface area. You can't extract the heat fast enough, and a lot of internal parts of the CPU get extremely hot with indirect cooling and being surrounded by other hot transistors and such. Just spread everything out a little. Just because you have smaller trace widths doesn't mean you have to shrink everything down. Intermix different trace widths depending on the length of the traces (so that you don't lose a lot of juice to resistance). And I'm willing to bet that it's easier to design a CPU that's more spread out.

      Not a bad estimate. Considering computer fans typically move 20-30 CFM, although high-end fans which blow more than 50 CFM), you would need 10 to 15 piezoelectric fans to achieve equivalent volume air flow. In 5-24 quantites they cost $79, so that translates to $790 to $1185.

    in my early forties and very fit. I consider my body type as voluptuous with
    long legs and a pretty face. I work hard to keep my body hard and my butt and
    breasts firm. I'm still getting hit on and turning heads. My husband is very
    handsome and in excellent shape and a few years older than I. I know how to keep
    him happy and dominate him in the bedroom our sex life is superb and we'll try
    just about anything once and if it's good we'll even do it again. I haven't told
    anyone about this sexual adventure we had a few months ago - it's a classic and
    I know many of you have thought of this but for whatever reason kept it locked
    away in your to do fantasy list.

    My husband is adventurous and enjoys risk; I on the other hand am very ethical
    and conservative for the most part. However periodically I get hyper-horny and
    will try anything honestly I feel like a lustful man trapped in this tight
    female body. And when one of his fantasies is introduced during my hyper-horny
    cycle - look out! Charlie (my husband) took me shopping. I know when he does
    this that he's trying to buy my affection so that I will reward him with sexual
    favors (I trained him well) so after buying everything on my wish list I asked
    him to pick something out for me to fashion tonight because we were going out on
    the town. I whispered in his ear, "I'll wear anything you desire". He's has
    great taste in clothes but borders he the line with Cheap - when he's horny. In
    other words he likes me a little on the trashy side. I got my nails done and
    hair styled and took full advantage of his finances.

    Later that night -

    I walk into the bar with a short black skirt, heels and a sheer see-through
    black sleeveless top. Underneath I'm wearing a tight see-trough latex body slip
    and absolutely no underwear of any kind. Men are so easy and I knew the women
    would hate me and the men would lust. I felt sensual and exotic to a point of
    pornographic with my new attire so what did I care as long as my man is happy. I
    was getting wet thinking about sex and thirsting for something between my legs
    to stuff my hole. Charlie was proud of me and paraded me like he won a prize and
    I was the reward so I played the role to a tee. He gets aroused when other men
    lust after me and I know this man would love to see me get fucked by a strange
    cock in the heat of passion but only when he's obsessed with lust and I'm a
    nymphomania hot bitch.

    We sat across from one another at the table and my black skirt barely covered my
    legs exposing my naked thighs so I crossed my legs and elevated my breasts in a
    straight posture. After a few drinks the alcohol was taking it's affect on the
    both us since we didn't normally indulge in alcoholic beverages. I noticed the
    bulge in Charlie's slacks and that he was prepared to jeopardize all his morals
    for this erotic fantasy. The daring thought of his untamed talks made me wet
    causing multiple orgasms while he shared one fantasy after another. I was
    getting frigidity crossing and opening my legs just the feel of my inner thighs
    was causing a tingling sensation throughout my body. I took deep breaths and
    moaned quietly to help relieve my pornographic hunger. I noticed the man sitting
    behind Charlie couldn't take his eyes off me and watched diligently every move I
    made and his date was getting very angry. I felt naughty so I taunted him a
    little while flirting with my husband by widening my legs to feel the bar breeze
    caress my swollen vulva. I was so wet! His reaction was driving me crazy and now
    Charlie knew what I was doing and he said, "Do you like teasing other men as
    much as I enjoy watching?" I replied, "He's been staring at me since we sat down
    so I thought I would give him something to dream about because what I have is
    only for you babe". And I reached under the table to stroke my husband's
    erection with a dirty sensual smile. Charlie said, "Rub your pussy with the tip
    of your fingers and give me a taste". I closed my eyes and followed his
    instructions the sensation was overwhelming and heavenly I could almost scream!
    I opened my eyes to watch Charlie suck my fingers like a newborn babe. I brought
    both legs together and tightened my posture feeling the sensation of another
    orgasm. In the worse way I wanted Charlie's cock in my mouth - I love to wrap my
    tongue around his thick cock.

    I noticed my voyeur was alone and dominated by my performance. I told my husband
    who suggested I should reward him for his perseverance. "What do you suggest I
    do?" I replied. He said, "Surprise me you slut". Being called a slut caused me
    to shiver with a tingling sensation. I was ready to fulfill all his fantasies.
    All I could think of was dick - I needed dick and I was so hyper-horny! My eyes
    locked onto to the voyeur as I walked slowly over to his chair. I stood in front
    of him without saying a word (I was afraid if I said anything that I would
    mutter from the affect that the drinks has caused) The voyeur touched my leg and
    slide it slowly up - up - up to my inner thigh and turned to caress the back of
    my ass with the palm of his hand. I was frozen and closed my eyes with a gentle
    moan. I was in ecstasy and he slowly moved around my pussy without making
    contact - I could of cried and hungered for the touch. I looked over and Charlie
    smiled with approval so I reached down to grab his bulge and gave him a kiss on
    the mouth. His hand elevated to my wet pussy - finally - I descended and locked
    his hand on my pussy by clamping my legs together. My body rushed with
    excitement; I had never done anything close to this in my life but the risk was
    overwhelming making me out of control with lust. I didn't care what Charlie was
    doing I wanted this man inside of me - NOW. I cried softly in his ear, "Fuck me
    - please fuck me." He said, "Let's go get a room". I asked him to wait. I went
    back to Charlie and asked if he would come to instruct me?

    All three of us entered the room together and immediately Charlie took his pants
    off in the chair and stroked his cock. "Come and suck this babe". I slowly and
    teasingly strolled over to him licking my lips and down on him I went with my
    mouth wide open devouring his erection as I have done so many times before. I
    was thinking how delicious it was when suddenly I felt the stranger's hands on
    my butt lifting up what was left of my short black skirt covering my ass. I
    could hear him unzip his pants and suddenly he was guiding his hard cock right
    into my unadulterated pussy. I could feel the throbbing head of his cock in my
    pussy and I lost complete control. The thought of two cocks in me at once was
    exhilarating! I moaned and cried with pleasure listening to Charlie telling the
    stranger what a good lover I was and how sweet my pussy tasted. Instructing him
    to fuck me harder deeper and faster. Calling me names while I was lost in this
    lustful passionate adventure. I suddenly felt an explosion of hot juices in my
    cunt and then in my mouth! I was soaked at both ends of my body - but the taste
    was fantastic! I slurped every drop of hot cum and the stranger removed his cock
    from my cunt I turned and thanked him asking him to leave his number on the
    table. He said, "Anytime Lady - just call and I'll be back in a heartbeat -
    that's one hell ova wife you go there." He left the room and Charlie and I
    continued on all night fucking each other until daybreak. But we have never
    discussed the evening since that night. But I often look at the number just
    waiting for Charlie's instructions...I never got his name? I get wet at the very

    Title: 13 December 2001 Cumulative Patch for IE
    Date: 13 December 2001
    Software: Internet Explorer
    Impact: Run Code of an Attacker's Choice
    Max Risk: Critical
    Bulletin: MS01-058

    Microsoft encourages customers to review the Security Bulletin at:
    http://www.microsoft.com/technet/security/bullet in /MS01-058.asp.

    Issue:
    This is a cumulative patch that, when installed, eliminates all
    previously discussed security vulnerabilities affecting IE 5.5 and
    IE 6. In addition, it eliminates three newly discovered
    vulnerabilities.

    - The first vulnerability involves a flaw in the handling of the
    Content-Disposition and Content-Type header fields in an HTML.
    stream. These fields, the hosting URL, and the hosted file data
    determine how a file is handled upon download in Internet
    Explorer. A security vulnerability exists because, if an
    attacker altered the HTML header information in a certain way,
    it could be possible to make IE believe that an executable file
    was actually a different type of file -- one that it is
    appropriate to simply open without asking the user for
    confirmation. This could enable the attacker to create a web
    page or HTML mail that, when opened, would automatically run an
    executable on the user's system. This vulnerability affects
    IE 6.0 only. It does not affect IE 5.5.

    - The second vulnerability is a newly discovered variant of the
    "Frame Domain Verification" vulnerability discussed in Microsoft
    Security Bulletin MS01-015. The vulnerability could enable a
    malicious web site operator to open two browser windows, one in
    the web site's domain and the other on the user's local file
    system, and to pass information from the latter to the former.
    This could enable the web site operator to read, but not change,
    any file on the user's local computer that could be opened in a
    browser window. This vulnerabilty affects both IE 5.5 and 6.0.

    - The third vulnerability involves a flaw related to the display
    of file names in the File Download dialogue box. When a file
    download is initiated, a dialogue provides the name of the file.
    However, in some cases, it would be possible for an attacker to
    misrepresent the name of the file in the dialogue. This could be
    invoked from a web page or in an HTML email in an attempt to
    fool users into accepting unsafe file types from a trusted
    source. This vulnerabilty affects both IE 5.5 and 6.0.

    Mitigating Factors:
    File Execution Vulnerability:

    - The vulnerability could not be exploited if File Downloads have
    been disabled in the Security Zone from which the file is being
    received. In most attempts to maliciously exploit this
    vulnerability the file would be received from the Internet or
    Intranet zone. Therefore, disabling File Downloads in these zones
    can protect customers. This is not the default setting for either
    of these zone, however.

    - This affects IE 6.0 only.

    Frame Domain Verification Variant:
    - The vulnerability could only be used to view files. It could not
    be used to create, delete, modify or execute them.

    - The vulnerability would only allow an attacker to read files that
    can be can be opened in a browser window, such as image files,
    HTML files and text files. Other file file types, such as binary
    files, executable files, Word documents, and so forth, could not
    be read.

    - The attacker would have to have knowledge of the exact file name
    and location in other to successfully read the file on the
    local system.

    File Name Spoofing Vulnerability:
    - The determination on choosing to accept a file download from an
    Internet site should always be based on the trustworthiness of
    the source and not on the file type. File downloads should never
    be accepted from an untrusted source, no matter how harmless the
    type may appear to be.

    Risk Rating:
    - Internet systems: Critical
    - Intranet systems: Critical
    - Client systems: Critical

    Patch Availability:
    - A patch is available to fix this vulnerability. Please read the
    Security Bulletin at
    http://www.microsoft.com/technet/security/bulletin /ms01-058.asp
    for information on obtaining this patch.

  47. My childhood days with CmdrTaco, by Jon Katz by Genghis+Troll · · Score: -1

    It all began when CmdrTaco called me and invited me to go camping with him
    and another friend of his, Hemos. We were going to be entering sixth grade in
    the following week, so he wanted to do this as sort of a last hurrah for
    summer. I immediately agreed. After I got mom's ok, I packed my backpack and
    tied my sleeping bag to the bottom, and headed over to CmdrTaco's house.

    CmdrTaco's house was a large ranch house at the end of the dirt road I lived
    on. Behind it, the trees and overgrown flora and wilderness seemed to stretch
    on forever. We had gone treking through the woods many times, and had camped
    out there a couple of times previously, both times with parental supervision.
    This time, CmdrTaco's dad decided it would be all right for us to go off by
    ourselves, and we left.

    It was a hot summer evening, and by the time we lost sight of the house,
    we were already hot and sweaty. After talking about it, we decided to camp
    by the large pond about two miles into the woods. That way, once we got
    camp set up, we could take a swim.

    The water of the pond looked cool and inviting when we first saw it, and
    it took a lot for us to put the small tent up first, and spread the large
    beach towels near the edge of the pond.

    As we started to take our clothes off, I watched CmdrTaco out of the corner
    of my eye. We had been friends since kindergarden, and there was very little
    we didn't share. Yet, for the first time, I began to notice how well-formed
    CmdrTaco's body was. He was a bit taller than me, and his chest was smooth and
    tan. He had a trim waistline, and his ass was small and delicate.

    I noticed that, as I took off my underwear, my dick was growing larger.
    I remembered that CmdrTaco had told me about jacking off, earlier that summer,
    and had told me how to do it. I did, and the feeling was the most intense
    pleasure I had yet felt in my young life. I knew that if I kept looking at
    CmdrTaco's ass, I'd have to jack off before long, so I jumped into the pond.

    CmdrTaco and Hemos jumped in behind me, and we laughed and splashed each other
    with the cool, clean pond water. All the activity was just getting me harder,
    and I knew I'd have to jack off soon or go crazy.

    Just then, Hemos pushed me into CmdrTaco, and I felt my boner press into his
    thigh. I also felt his boner press into my abdomen. My face must have turned
    bright red, because CmdrTaco immediately said, "Hey! Katz's got a boner!"

    "You do too!" I replied, grinning. He splashed me with water, but
    laughed.

    "That makes three of us with boners," Hemos said. He stood with the water
    just touching the bottom of his balls, his twelve-year-old cock standing at
    attention. CmdrTaco laughed and playfully grabbed at Hemos's boner. I groped
    CmdrTaco's boner and Hemos groped mine.

    After several seconds, we decided to get out of the water. We sat down
    on the beach towels, our erections still standing out. We poked at each
    others' boners for a few minutes.

    "Man, I have got to jack off," CmdrTaco said, saying what was on both my
    mind and Hemos's. Hemos, who had been groping CmdrTaco's balls, wrapped his hand
    around CmdrTaco's six inch long meat and started pumping up and down. CmdrTaco's
    face turned red, but he didn't push Hemos's hand away. I watched, wondering
    what they were going to do next.

    When Hemos bent over CmdrTaco's lap and started licking CmdrTaco's dick, my own
    boner got even harder. CmdrTaco leaned back on the blanket, and Hemos slid CmdrTaco's
    cock into his mouth. I watched, fascinated, as Hemos went up and down,
    slurping, on my best friend's dick. CmdrTaco groaned loudly, his breath getting
    shorter and shorter. Hemos made an almost purring sound as he sucked CmdrTaco,
    and I knew what was going to happen next.

    CmdrTaco came in Hemos's mouth, and he cried out loudly when the orgasm hit
    him. Hemos kept sucking on CmdrTaco's meat, drinking down his adolescent fluids.
    Some dribbled out of a corner of his mouth, and Hemos licked it up, and kissed
    CmdrTaco's cock as it started to soften.

    I suddenly realized that I had my own hand around my cock as I had been
    watching them. "Wow..." I managed to say. "That looked great."

    "Do you want me to suck you?" CmdrTaco asked. The thought of a hot mouth
    around my cock sent a shiver of pleasure through me.

    "Yes!" I replied, opening my legs and moving my hand from my cock. CmdrTaco
    leaned over and touched my cock, stroking it gently. He wrapped his hand
    around the five and three quarter inch shaft and squeezed gently as he leaned
    forward. I could feel his breath hot on my boner, and I moaned with low
    passion.

    CmdrTaco's tongue touched my cock tip, and the electric heat made me groan
    louder. He licked around the head in a clockwise spiral, then trailed down
    the shaft to my smooth, hairless balls. He took one, then both in his mouth,
    and I squirmed where I lay, amazed at how good it felt to have my balls in
    another boy's mouth. Then, he let them out and licked his way back up to
    the tip, and took the head in his mouth.

    Slowly, my temperature rose as my cock slid further into his mouth. I
    was in ecstasy when he got it all in his mouth, and my meat was fully
    encased in his hot, wet mouth. "Suck me..." I moaned, and CmdrTaco started to
    bob up and down on me like Hemos had bobbed on CmdrTaco earlier. His strokes
    were long and slow, and each one produced a wave of pleasure that rolled
    through me.

    He increased the pace, and I started to feel my balls tingle. The
    slurping, smacking sounds he made sounded like music to my ears, and I
    started to moan louder and louder.

    I stiffened, and knew I was about to come. When my orgasm arrived, it
    was a blast of pure passion that tore through me, as my salty load shot out
    into CmdrTaco's waiting mouth. CmdrTaco gulped down the cum, and still kept sucking
    me, as I squeezed more out. A wave of pleasure, greater than any I'd ever
    had while jacking off, had me riding high for minutes.

    Finally, I started coming down, and my dick started to lose it's
    hardness. CmdrTaco got up, leaned over, and kissed me. I opened my mouth, and
    his tongue slipped inside, and I tasted my own cum. I kissed CmdrTaco back,
    realizing that our friendship had taken a further step into love.

    When we finally broke away, I said, "That was wonderful, CmdrTaco. Can we
    do it again?"

    "Sure," CmdrTaco replied. "But not right away. It'll take you a while to
    be able to get another boner. Same with me."

    "Have you done this before?" I asked.

    "Only with Hemos," CmdrTaco said. "He taught me what to do, and now he's
    going to teach you. Come over here." CmdrTaco took my hand and guided it over
    to Hemos's cock, which was standing up from where he had been watching. I
    gripped the cock, feeling the warmth and the gentle pulsing under my hand.
    I squeezed, feeling it's thickness.

    "Don't squeeze so hard," Hemos said. "Nice and gentle...that's it." I
    squeezed it less hard and started to stroke his cock, all the while leaning
    closer and closer to it. "That's it, go ahead and lick it." Hesitantly,
    I put out my tongue and touched the tip, and was surprised when it jumped.
    I licked it again, trying to imitate the circular motion on the head that
    CmdrTaco had done for me.

    "Okay, now take the head into your mouth," Hemos instructed. It slid in
    gently, a warm presence inside my mouth. "Okay, now slide it in slowly...
    watch the teeth...that's it...oh, god, yes..." As he sank further into my
    mouth, I marveled that a boy's cock could taste so good.

    When the cock tip touched my throat, I gagged. "Just relax your throat,"
    Hemos said. "Let it slide past." I closed my eyes and let it slide further
    in. The impulse to gag returned breifly, then went away, and soon, I had his
    whole six inch cock in my mouth.

    As I started going up and down on his cock, CmdrTaco head ducked under mine
    and I could see his tongue licking Hemos's balls. I shifted around to the
    side, to give CmdrTaco more room, and kept sucking on Hemos.

    Hemos moaned loudly, and I knew that we were starting to make him feel
    good. CmdrTaco had Hemos's balls in his mouth, and he was fondling my soft cock
    with his left hand. I shivered, knowing that I'd have another boner before
    the night was through.

    "I'm gonna cum!" Hemos called, and soon enough, his cum started shooting
    out of his cock and into my waiting mouth. CmdrTaco lifted his head up and
    started licking the corner of my mouth, which had started to leak cum. I
    took my mouth partially off Hemos's head and CmdrTaco took the other part, our
    lips meeting as we drank Hemos's delicious boy juices. He tasted so good!

    Finally, Hemos was drained, and he laid back, a big smile on his face.
    CmdrTaco and I shared a cum-laced kiss, then snuggled up to Hemos on the blanket,
    both of us taking turns in exchanging long french kisses with him.

Apply the voltage, and heat was moved actively into the outside heat sink, enough to chill your beer and keep the fish fresh on the trip home.

    THE OFFICIAL TACO-SNOTTING FAQ By The WIPO Troll, $Revision: 1.12 $

    Why have I been receiving emails from CmdrTaco, in which he seems to be speaking in some kind of code language?

    Whenever Rob "CmdrTaco" Malda gets bored (and who wouldn't, running a site like Slashdot all day), he roams through the Slashdot database, penis in hand, looking for people who might enjoy engaging in homosexual orgies with him. How he determines this is anyone's guess; but if you have a homosexual-sounding nickname, or a nick with the letter P in it, you're in trouble.
    So this time, he found you. Lucky you.
    CmdrTaco's code language is relatively easy to decipher. He prefers to speak in thinly-veiled sexual innuendo to evade the watchful (but relatively stupid) eye of Slashdot's parent corporation, VA Software. CmdrTaco's "Commander" is, of course, his penis -- a small, withered little thing that lives in his pants that only comes out in the presence of other men or at the beck and call of CmdrTaco's own right hand. His "Taco bells" are the shriveled testes that droop beneath his Commander, and his "Taco sauce" is his, well, jizz. It should be more than obvious to you now what he means when he asks you to "ring his Taco bells" or "taste his gourmet Taco sauce."
    Lastly, there is a practice he refers to as "Taco-snotting" and the more shocking "circle-snot."

    Good Lord. What is "Taco-snotting?"

    "Taco-snotting" is the term used by CmdrTaco to refer to the practice of sucking the penis of a homosexual man (or unwilling heterosexual; CmdrTaco is rumored to prefer rape), then blowing the semen out his nose onto his partner's (victim's) face and body. A long, bubbly stream of milky-white semen is left on CmdrTaco's face, dribbling out of his nose and down his cheek: hence the term, "Taco-snotting."
    A "circle-snot" is a Taco-snotting circle-jerk, another practice common among the Slashdot crew. CmdrTaco, CowboiKneel, and Homos get together and Taco-snot each other with their gooey, sticky cum -- spooging their jizz-snot all over each other's faces and pasty, white bodies, until they're covered head to toe with each other's man juice. This can go on for hours. For the homosexual penetration that follows this lengthy foreplay, Roblowme is usually there to provide plenty of anal lubricant; he owns a limo service and has ample supplies of motor oil and axle grease ready to go.
    To complete this perverted orgy, fellow geeks Michael, Timothy, and Jamie will usually join in, dressed in tight leather mock-S.S. uniforms, jack boots, and leather gloves. The whole group then proceeds to snot each other's spunk and whip each other's pudgy asses with riding crops and chains until their pale, white geek bodies are exhausted and soaked in stinking sweat from the hours of passionate, homosexual revelry.

    Ewwwwww. So, can I stop receiving these emails?

    Hopefully.
    You most likely forgot to uncheck the "Willing to Taco-snot" checkbox in your account preferences. CmdrTaco has probably already got the hots for your wad, and he's probably already been lurking outside your bathroom window for weeks with a camera, some tissues and lube. There's no escaping a geek in heat, so it's probably too late for you, but you can possibly rectify this situation. To remove yourself from CmdrTaco's sights, log into your Slashdot account, go to your user page, click on Messages, and uncheck the box next to "Willing to Taco-snot." Maybe he'll ignore you. Probably not.

    I can't stop receiving these emails from CmdrTaco!?

    If you indulge him in a Taco-snot or two, he might leave you alone. You might also want to look into mail filtering, restraining orders, or purchasing a heavy, blunt object capable of warding off rampaging homosexual geeks in heat. Trust me, when they charge... oh, the humanity. If he gets you, and you let him Taco-snot you, you will most likely end up tied up in his basement to be used as his sex slave for the rest of your life (or until he accidentally drowns you in spunk in a circle-snot).

    Have you ever been Taco-Snotted?

    Unfortunately, yes. I first met CmdrTaco at an Open Source Convention. He invited me back to his room for a game of Quake and some "gourmet Tacos," but when I got there, he jumped me and tied me to his bed, stripping me. After taking his "Commander" out of his pants, Mr. Taco made me suck the withered thing six times. He then performed his vile Taco-snotting ritual on me three times over the next two hours, bringing me to orgasm after sweaty, mind-numbing orgasm... then he snotted my own milky-white jizz back onto my face, into my mouth, then again on my exposed belly.
    CmdrTaco invited several of his Open Source (or rather, "Open Sauce" -- man sauce) buddies over to continue the twisted snotfest. Linux Torvalds raped my ass with his "monolithic kernel," and Anal Cox used his "network stack" in a multitude of unspeakable ways on and in every orifice in my defenseless body. Michael was there in his leather Nazi uniform, caning my ass with a bamboo pole and ranting about "all those Censorware freaks out to get him."
    How did you finally escape, you ask? After about 16 hours of countless homosexual atrocities perpetrated against my restrained body, they all finally went to sleep on top of me, sweat-soaked and exhausted. I was left there, covered in bubbly, translucent jizz-snot, chained to the bed, with half a dozen fat, pasty-white fags lying around and on top of me. Fortunately the spooge coating my flesh worked wonderfully as a lubricant; I was able to squirm my way out of the handcuffs and slip out the back door. I'm just glad I survived the ordeal. These geeks had a lot of built-up spunk in their wads -- I could've easily been drowned!

    That's horrible. Does "Taco-snotting" have anything to do with CmdrTaco's "special taco"?

    No, that's a different disgusting perversion CmdrTaco indulges himself in. CmdrTaco is usually not satisfied with merely snotting your own jizz back onto your face, he most often enjoys involving his own bodily fluids in his twisted games. WeatherTroll has spent some time trying to educate the Slashdot readership about this vile practice (emphasis added):
    You may be wondering what CmdrTaco's "special taco" is. You will be wishing that you hadn't been wondering after you finish reading this post. To make his "special taco", CmdrTaco takes a taco shell and shits on it. He then adds lettuce, jacks off on the taco, and adds a compound to make the person who eats the taco unconscious. Of course, the compound does not make the person unconscious until the taco is fully eaten. Thus CmdrTaco force-feeds the taco to the unsuspecting victim.
    After the victim is unconscious, he is held against his will and used for CmdrTaco's nefarious sexual purposes. This includes shoving taco shells up the victim's ass, Taco-snotting, and getting Jon Katz involved.
    Completely different, yet no less revolting. It should be clear to you now that CmdrTaco is a very, very sick individual, as are most of the Slashdot editors.

    Does Jon Katz get involved in any of this? I thought he was a paedophile, not a homosexual.

    Actually, Jon Katz is a homosexual paedophile. He's also a coprophiliac, and, many suspect, a zoophile. Jon Katz is somewhat of a loner and doesn't involve himself in circle-snots. Mr. Katz usually engages in a game called " Katz juicy-douching" with his harem of little-boy slaves: a vile practice which involves administering an enema to himself of the little boy's urine (forced out of them with a pair of pliers), spooging the vile muck from his ass back into the enema bag, then squirting and slathering the goo all over himself, and the little boy's chained-up and naked bodies. If he's in the mood, he will sometimes skip refilling the enema bag and just squirt it from his ass onto his boys. Unwilling boys are further tortured with the pliers until they comply and allow Mr. Katz to juicy-douche them for the rest of their lives.
    As I already said, Mr. Katz is also a zoophile. As if the sexual escapades with the helpless little boys aren't enough, Jon usually enjoys his juicy-douches best when his penis is firmly planted in a female goat's anus. He is also rumoured to get off on watching his little boys eat the goat's small, bean-like turds.

    ...Are you getting hard writing this?

    Why, yes. :) Join me in a WIPO-snot?

    No, thanks. I'm already CmdrTaco's boi toi.

      When heat is the problem keeping them from making a product that is useful and marketable they'll change it. Until then they focus on other things, and they make you buy a heat managment accessory.

      What's so hard to understand about that?

  82. failing of linux by Anonymous Coward · · Score: -1, Offtopic

    Let's have a close look at the costs involved when running a Linux system.

    An important factor in Linux' cost is its maintenance. Linux requires a *lot* of maintenance, work doable only by the relatively few high-paid Linux administrators that put themselves - of course willingly - at a great place in the market. Linux seems to be needing maintenance continuously, to keep it from breaking down.

    Add to this the cost of loss of data. Linux' native file system, EXT2FS, is known to lose data like a firehose spouts water when the file system isn't unmounted properly. Other unix file systems are much more tolerant towards unexpected crashes. An example is the FreeBSD file system, which with soft updates enabled, performance-wise blows EXT2FS out of the water, and doesn't have the negative drawback of extreme data loss in case of a system breakdown.

    According to Linux advocates, an alternative to EXT2FS would be ReiserFS. Unfortunately, ReiserFS is still in beta stage. This means it is not intended for production use (although according to many Linux advocates this shouldn't be a problem, which makes me wonder how (little) valuable they find your data).

    The other proposed 'solution', EXT3FS, is nothing more than an ugly hack to put journaling into the file system. All the drawbacks of the ancient EXT2FS file system remain in EXT3FS, for the sake of 'forward- and backward compatibility'. This is interesting, considering that the DOS heritage in the Windows 9x/ME series was considered a very bad thing by the Linux community, even though it provided what could be called one of the best examples of compatibility, ever. When it's about Linux, compatibility constraints don't seem to be that much of a problem for Linux advocates.

    Back to Linux' cost. Factor in also the fact that crashes happen much more often on Linux than on other unices. On other unices, crashes usually are caused by external sources like power outages. Crashes in Linux are a regular thing, and nobody seems to know what causes them, internally. Linux advocates try to hide this fact by denying crashes ever happen. Instead, they have frequent "hardware problems".

    The steep learning curve compared to about any other operating system out there is a major factor in Linux' cost. The system is a mix of features from all kinds of unices, but not one of them is implemented right. A Linux user has to live with badly coded tools which have low performance, mangle data seemingly at random and are not in line with their specification. On top of that a lot of them spit out the most childish and unprofessional messages, indicating that they were created by 14-year olds with too much time, no talent and a bad attitude.

    I could go on and on and on, but the conclusion is clear. Linux is not an option for any one who seeks a professional OS with high performance, scalability, stability, adherence to standards, etc.

    Gluing a piezo fan onto the chip is not very smart anyway. And it does generate some 'flexing' heat where there is the least air motion. And it makes noise like a butterfly on speed.

    You don't get something for nothing. Moving air other than by convection causes turbulence which causes vibrations. Vibration IS noise. Which is more irritating, a flapping buzz or a whirling whoosh? Its a matter of taste.

  95. Caveats of Piezoelectric Crystals by SloppyElvis · · Score: 1

    We used piezoelectric crystals in a Genomics Lab at the University of Wisconsin and there are two problems that immediately come to mind at the mention of this application (and an afterthought).

    For one, they are very costly. Perhaps with their proliferation, the costs would go down, perhaps not.

    Second, piezoelectric crystals are very fragile. They have a tendency to crumble when too much force is applied to them. Unless this problem has been solved, transport of such a device could easily cause damage. See point #1.

    Afterthought, there may also be a problem with condensation associated with the use of piezoelectrics. Without the air flow of a fan, devices of this sort are subject to water vapor condensation, which, as everybody knows, is a bad thing to have happening on your mother board. In an analogous situation, my brother and I tried using Peltier junctions to cool our hot rod, and the result was a watery mess. (Coincidentally, I now work for an unnamed company that relies on Peltier junctions for rapid thermal cycling, and to solve the condensation problem, we have relied on, you've got it, heat sinks and fans).

This was a dead end.

    A more recent development has been to set aside these preconceptions and use the unique properties of superconductors. If you have a ring of superconductor, you can trap a quantum of magnetic flux in it- this corresponds to a bit of current flowing eternally around the ring. If a Josephson junction is part of the ring, it can, by changing state, release the flux quantum, creating a voltage pulse. Google for 'RSFQ' and you'll find lots more information.
