Wriggling Heat Sinks

YourHero writes "Purdue researchers have come up with a new way to cool chips, in about 2 years. Just build a bunch of little piezoelectric fans (the waving kind, not the spinning kind). Since they don't spin, no bearings, less self-generated heat. Since they don't have magnets, no electromagnetic noise problems. And, of course, super-efficient. A press release and abstract for your reading pleasure. Formal presentation at THERMES 2002 Jan 15th."

    It's best if I tell you a little about me so you can understand this story. I'm
    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
    thought of the evening we had. At least now I know what I want for my birthday
    gift!

    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.

  30. 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.
