yea, nobody ever remembers me, but when you get bored, and start reading the porn stories that pop up in the comments today, realize that i'm responsible.
web server.. and then make sure that your webmail client supports connecting to remote hosts. most webmail applications use IMAP or POP3, and in those, you can specify WHICH SERVER you wish to connect to... in this case, a user connecting to the web front end would allow the webserver to connect to the mail server via IMAP/POP3, and the mail server wouldnt need any traffic to 80 at all.
You are truly stupid. Do you have no idea what's going on? Do you not realize that the site is/.'ed? This is the complete opposite of "offtopic", it's, by definition, on topic, as it is a MIRROR FUCKING COPY of what nobody else can see.
this has been proposed before, and they have a good reason for NOT caching news stories: it takes control of the story out of the hands of the original poster, making it unable for the person to shut down their site if they want privacy, and making slashdot responsible for posting potentially illegal material (remember all the DeCSS things linked to in the past?)... they cant cache it, but they should at least warn the webmasters before posting it. Typically/.'ing is just a misconfigured (max processes = 15 by default, right?) apache server, especially in a university setting.
Continuing the theme of combustion this is an attempt to model an
incident that occurred in a small garage local to where MH lives in
Sheffield. In these spectacular
experiments dihydrogen, diethyl ether and alcohol are burned.
Liquids that vaporise easily
at ambient temperature to form heavy vapours pose particular hazards during
handling e.g. when transferring from one container to another, or when spilled.
Petrol is the most common of these fluids and serious
accidents have occurred during handling due to flashback from sources of
ignition often at considerable distance away. Because the heavy vapour spreads
along the ground it does not readily defuse into the air and become diluted
below its explosive/flammable limit so the, even outdoors, it can be very
dangerous. People attempting to kindle garden fires or BBQ's with petrol have
all too often been engulfed in flames due to the spread of the vapour beyond
the intended area. Similarly liquid petroleum gas (LPG) has also caused
appalling accidents when 'fire balls' have formed due to the ignition of dense
clouds of the gas. Butane has a density of more than twice that of air.
These experiments attempt to simulate, and so
demonstrate, this phenomenon. Diethyl ether
is used because it has a combination of high vapour pressure (440mm Hg at 20C)
and density (2.55 {air = 1}) and has been responsible for many accidents in the
laboratory and the chemical industry where it is often used as a solvent in
chemical processes.
In the first demonstration a length of extruded aluminium
angle is set up to form a channel along the length of the lecture bench (some
five meters) such that one end is at bench level and the other some 150cm
higher. In the video this is said to represent the floor of a garage (set
sloping in order to reduce the experimentation time) and a wad of burning
cotton wool soaked with a little alcohol at the lower end is said to represent
someone welding (a source of ignition). Balloons are attached at the high end.
These are filled with hydrogen gas except the yellow one to which a little
oxygen had been added in addition to the hydrogen (the story line has these to
emphasise the effect of a leaking fuel tank exploding). Sufficient diethyl
ether wars added to the high end of the channel (representing a petrol leak)
such that it was all vaporised by the time it had reached about half way down.
The heavy vapour continued down the remaining 2.5m and was ignited on reaching
the 'welder'. The thunderous sound of the explosion it impossible to reproduce
from the video but some compensation is afforded if the exploding balloons are
played back frame by frame.
The speed of the (defusion) flame front along the channel
was quite slow due to the lack of mixing of the vapour with the air. In reality
air movement, particularly if it were outdoors, would pre mix some of the ether
and air. The second experiment attempts to simulate this. The storyline here is
that the space enclosed by the Perspex safety screens represents a laboratory
and the candle represents a Bunsen burner. Diethyl ether (15ml) is spilled on
the floor a metal tray and left to evaporate. Later a small electric fan is
started to create a draught and so mix the vapour and the air. When this
pre-mixture reaches the source of ignition the resulting conflagration is very
rapid and if were much larger or confined, an explosion would occur. See also
experiments 7 and 15a.
This is one occasion when seeing it in real time is less
impressive than the series of single frames, there are 25 each second. The
series of diagonal stripes from top left to bottom right, to be seen on one of
the frames, are vertical, or near vertical, oscillations (pressure regions).
They are slanting because of the way the image is scanned by the camera, left
to right, top to bottom.
By using
video frames as units of time (each represents 40ms) the relative velocities of
the near diffusion flame-front and the pre-mixed flame-front can be, roughly,
determined. Since the same
synchronisation pulse as received by all three cameras any combination could be
used for this purpose. I used camera
three for the (near diffusion) flame on the channel and counted the number of
frames that showed it passing the front of the safety screen enclosure. The images
on the video are from another camera and are not useful for this. I used frames
from camera one for the pre-mixed flame-front which is the one use for the
video at that time. I got the following results:
Number of frames taken for the 'diffusion' flame to
traverse the enclosure front = 17 (= 680ms)
Number
of frames taken for the pre-mixed flame to traverse the enclosure front = 7 (=
280ms)
Relative
velocities 680/280 = 2.4.
So the pre-mixed flame
travelled about two and a half time faster than the diffusion flame. However,
until the flame was bounded by the walls of the enclosure the increase in
volume was 2.43 faster i.e. about 14 times!
HAZARDS
The main hazards are exemplified by the demonstration itself.
. Diethyl ether has a high vapour pressure
(440mm Hg at 20C) and density (2.55 {air = 1}) and a low auto ignition
temperature (not flash point!) of between 180 and 190C. Air/ether mixtures
containing >1.85% v/v of diethyl ether vapour are constitute an explosive
hazard.
Explosive peroxides (ethylidene peroxide polymers') may be
formed on exposure to air and light, and particularly when evaporated to
dryness. These peroxides have been known to form around the stoppers of
container of diethyl ether that have been left unopened for long periods. Although not relevant to this experiment it
is worth pointing out that ether is a good electrical insulator and when very
dry (saturated ether contains 1.2% water at 20C), shaking etc. can produce
sufficient static electricity to cause ignition of the vapour.
Diethyl ether is mildly
irritating to skin and mucous membranes. Inhalation of high concentrations
causes narcosis1.
Hydrogen gas is very
flammable and yields explosive mixtures with air. The stoichiometric mixture should be avoided because the explosion
is too loud. The audience should be, at
least, three meters from the balloons.
DISPOSAL
Immediately after the
explosion a careful check should be made to make sure that no debris from the
balloons are burning2. I
have performed this demonstration over 70 times (>280 balloons) and have not found this to happen but one
should be aware that it could! The
cotton wool should be extinguished by covering with a watch glass and left to
cool.

It will offer many new revenue streams and enable households to be reached that are currently monopolised by very large companies."
And they dont expect this new technology to be bought, and exploited, by one of these already existing monopolies? And once purchased, don't they assume that it will just add to the existing monopolies?
Call me a skeptic, but this is going to be something that AOL or MS or someone pays a lot of money to buy, and then makes it completely proprietary. And that's assuming that it GETS to the consumer market without getting squashed by legal troubles.
ok, and what about the 3com driver/APIC updates that were supposedly fixed in the -ac tree (the ones that kept SMP boxes with APIC handling from dying under high network load with 3c905 network cards?), are these ever going to make it into the linus kernel?
We had to go buy new cards, because upgrading from 2.2 to 2.4 made backups impossible, as high network/processor load caused problems at least one night a week, forcing us to power cycle the backup machine.
It's now common knowledge that the database was brought down with a packet storm directed at port 3306, in retaliation for OSDN/Andover refusing to settle the sexual harassment case involving the female network admin who was fired after refusing to engage in oral sex with one of the editors.

Alice had been naughty. Her lover was away for the weekend and she was
... she rather liked it.
... and she loved it.

..." Alice began and thought better of it.

bored. When Dave called her, telling you about the concert tickets he had,
she knew what he wanted, but between the boredom and wanting to see the
concert (and Dave's build) she went.
Dave did everything he could to turn her on. He had drinks at his place
ready before she left. she sat out on the lawn at the pavilion, drinking
wine. He put his arm around her, and at every opportunity Dave touched her,
stroked her, patted her, massaged her.
He spent a good ten minutes rubbing her forearms when she talked about
typing much of the morning. He spent longer on her back, and the kiss at the
end had seemed so natural.
The three that followed were more forceful. She didn't protest when his
hand began rubbing her breast
On the way home his hand was under her dress as he drove, teasing her
pubic mound so that by the time she reached his apartment you were wet and as
horny as she could remember being. He took her on the rug in his living room,
and then later in his big bed.
For Alice, things had gotten out of hand
Dave had continued to maintain possession of either her breast or her sex
the whole drive home. When they had entered the house he had begun kissing
her in earnest as he undressed her. His tongue had explored her in ways she
had always refused to her lover, Mark. Dave had simply been insistent. He
had tongued her mouth--deeply. He had gone all over her neck, licking her
ears.
Alice had always made Mark stop when he had begun that. The sensation was
too--disturbing. Dave had simply ignored her. That alone had excited her.
The fact that she was also discovering a new erogenous zone on her body only
made matters worse.
Dave had continued. He had tongued his way down to her breasts, and
instead of liking and sucking the way Mark did, Dave had gone over her whole
breast, or rather both of them. It was flattering in a way, and just a little
gross.
Alice had been deeply aroused.
That first time in the living room, on the rug, Dave had not even waited
to completely undress her. He had taken off her bra and shirt, and then
pulled off her panties.
With her skirt bunched up around her hips he had forced her over the
footstool on her stomach and had her from behind, something she had refused to
allow Mark to do.
Her inability to control Dave made her feel terribly wanton as she allowed
him each liberty. She had come almost as soon as he had entered her, her
skirt still on, on her face, from the rear.
Dave was taking her like a bitch, she thought. The word "bitch" seemed to
excite her even more. She repeated it to herself as his hard member shoved
home, again and again.
When Dave had come, she had expected to get dressed, but instead he had
taken her to his bedroom, removed the rest of her clothes and made her assume
positions on his bed.
When she had refused, he had simply moved her to the desired position.
As she showed herself, he had stroked her mound, rubbed her breasts, and
generally tried to keep her horny.
It had worked.
He had gotten her ready to make love a second time by eating her. Alice
had resisted this. She had never allowed Mark to lick her after they had had
sex. It seemed so--Wrong.
Dave ignored her and went down on her, licking her with much more energy
than Mark did, making her come twice.
As she reached that stage of orgasm (the first time) when you lose control
of your body for a few seconds he had slid a finger up her ass and then had
continued to run it in and out of her in a fucking motion as he licked her
engorged slit.
He paid more attention to her pussy than Mark did. He licked the whole
slit, running his tongue up and down her whole length, even darting in and out
of her well fucked hole. He knew when he was getting to her and as the second
orgasm approached he went down on her with a gusto, matching each stroke of
his tongue with one from the finger in her virgin ass.
As she came the second time, Dave waited for her to relax and was in her
in a matter of two seconds.
She had come instantly, again.
Dave had settled down for a long screw. He had pulled her knees up to his
chest. He had pulled her legs straight and put them on his shoulders. He had
turned her hips on their side, screwing her all the while.
Dave had come a second time and had barely allowed her to get her breath
before his fingers were buried in her snatch.
"He's treating me like a bitch!" She thought. The thought made her hot.
He had played her body like a violin, keeping her on the edge of orgasm
for minutes at a time.
When she had had her fourth orgasm from his fingers, he had presented his
limp organ to her face. She knew what he wanted and she looked desperately
for a way out.
She had gone down on Mark (and to both boyfriends before him), but never
after sex. She didn't mind a clean cock, but to lick one that had just
That was too much.
But here was Dave, and she would have to admit that she was bothered by
something he obviously thought was fine. He had already gone down on her, and
after coming in her as well.
Alice stared at the organ. Dave took the back of her head and directed
her mouth to his cock.
In the end it was easier to suck his cock than it was to refuse.
Dave's cock had grown to its earlier proportions fairly quickly. Alice
was at least fairly sure that he didn't expect her to let him erupt in her
mouth. When he was hard he had continued to have her suck on him, guiding her
mouth up and down, setting the tempo.
Alice had begun to worry when he had pulled it out.
Dave turned her back over on her hands and knees. She had pulled two of
the pillows from the bed to put under her arms for support. He had reached
around and was fingering her slit from behind her.
Unable to hold still, she thrust her ass back at his cock. She wanted to
feel his cock inside her and, oddly, she was thrilled to be getting it on her
hands and knees again.
The phrase, "Like a bitch!" went on and on in her head as she shoved her
bottom out to receive his prick.
Dave entered her slowly. He seemed to want to slow her down, to make his
strokes as long as possible. After four strokes, he pulled out and put his
now well lubricated cock against the rosebud of her asshole.
He had the head in before she had stopped shoving her ass back at him,
trying to recapture his cock.
Dave had held her by her hip on one side and literally by her cunt on the
other so that she couldn't dislodge him. He had kept up the rubbing action on
her clit continuously so that she couldn't decide if it was painful
or--terribly exciting.
Dave continued, in small strokes, to shove his cock back further into her
ass. She had taken it all.
"Like a bitch!" She thought.
He had gone into her to the hilt and rested a moment before beginning to
fuck her ass.
"like a bitch!" Alice thought.
He had made her come from the dual pressure of his hand on her clit and his
prick in her ass.
"I'm coming, Like a bitch!'" She thought as her orgasm erupted.
Dave had kept her coming for nearly three minutes. His hands had had to
hold her in place to prevent her gyrations from unseating him.
Finally his spurting into her ass ended things and the two fell in a
semi-swoon on his large bed.
Half an hour later Alice had put on her skirt and blouse, her underwear
stuffed into her purse.
Dave had driven her home just before two in the morning. She had kissed
him in the car and walked up her steps to her house feeling very confused and
very satisfied.
Seeing Mark sitting in the chair in the living room had nearly stopped her
heart.
Alice's dress was wrinkled to death. Even if she had stopped to use
Dave's bathroom thoroughly, the dress alone would have shown what she had been
up to.
Mark stood up and asked if there was any point in his staying. Alice had
burst into tears.
Seeing Mark was a shock, but it had crystallized her feelings for her. It
was Mark she wanted, and she told him that.
"Mark, I know I've hurt you, but I do love you. I'll do anything to get
you to stay."
Mark had stopped. "Really? Anything?"
"Yes. Anything." Alice had managed to get both sorrow and defiance into
her voice at the same time.
"If I stay," Mark began, "I want an end to all your hangups about sex. If
you can screw around on me--"
"It wasn't
"You can stop telling me that things I want are dirty." Mark continued.
"That's the first thing."
"O.K. Mark, just don't leave."
"Second, you can spend the rest of the week showing me that you've turned
over a new leaf."
"I will, Mark, I will."
"Third, You'll have to pay for tonight, any way I think you should."
Alice thought of what she knew of Mark, and decided that she could endure
anything that he might come up with.
"Whatever you think is fair, Mark. Just remember I love you." Alice
answered.
"We'll see how much. Take off your clothes."
Alice had been afraid of this. The phrase, "Like a bitch." now had a new
meaning to her.
She had turned her back to Mark and taken off her shirt. She hung her
shirt on a chair, thankful that Dave hadn't been one for hickies. She took
off her wrinkled skirt with more trepidation. Mark knew she never went out
without panties.
"Turn around."
Alice tried to look demure. It was hard. Not only was she naked, but
freshly fucked as she was, there were still traces of Dave's come on her
and dripping out of her.
Alice wished fervently for a minute alone in the bathroom. She didn't
dare ask.
"Come here."
Alice walked slowly to him.
"Lay across my lap."
Alice had assumed that he would want to fuck her. A spanking hadn't even
entered her mind. She could barely remember her last spanking. She had been
in grade school and her mother had pulled down her drawers and used a hair
brush on her young ass after finding out about a fight in school.
With some genuine fear, Alice lay across his lap.
Mark didn't begin spanking her at once. First he spread her legs and felt
the sticky dampness there. Alice blushed hotly at the shame of having mark
examine the evidence of her infidelity.
Alice tried to hold still as Mark's fingers followed the traces up her
legs to her sex. His finger went on onto her mound, and after a second, right
into her well fucked hole.
It was while Alice was trying not to react to the shame of such an
examination that Mark slapped her ass for the first time.
"Count them."
"One."
And so it went to twenty-five. With each slap, Mark's finger explored
more of her cunt. Then with his fingers in her hole, and his thumb on her
clit, Mark had begun the inquisition.
He had insisted on each detail of what she had done, leaving out only the
name of her partner. Alice was so relieved that she held nothing back
for long.
At each new act, Alice had tried to hide how easily she had allowed
herself to be used by Dave. Each evasion brought not a new round of spanking,
but a new level of sensation on her clit.
By four A.M., weak with orgasms, Alice had told him every detail, save
one. She had not told him that she had gone down on him after he had fucked
her.
At four-thirty, Mark had allowed her a brief respite.
"I need to tell you some things." Mark had begun, "I believe you want me
to stay, and that you love me.
"I believe you will try to change, and I'll let your actions for the week
speak for themselves.
"I also know that you're still holding back something. We'll go over that
tomorrow night. I'm getting too tired."
Alice crawled up in his lap and kissed him several times. She had never
come so many times in a single night before.
"One last thing, "Mark continued, "listening to you has made me horny. As
long as you're naked, it seems like a waste not to do something about it."
Mark led her to their bedroom. He stacked pillows near the center of the
bed. He positioned Alice over them. Standing to one side, he undressed.
Alice's relief as he plunged into her pussy was short lived as he pulled
out and slid his variously lubricated cock into her ass.
THE END--
But soon to come:
Alice's Special Week.
This is my first posting
future if you like this, but must post anonymously, since I am
a senior manager at a Fortune 100 company and knowledge about
my extra-curricular activities would cause the end of my
career.
It was hot and steamy as we arrived at the airport in
Brisbane for the long journey home to Boston. This was the end
of a month-long campervan vacation in Australia, and I, for
one, was overjoyed to be heading back to some normalcy. For an
entire month my wife Anne (I call her "the queen") had avoided
sex in the campervan, or anywhere else for that matter, since
"the children are nearby." - The irony of her way of thinking
will be evident shortly.
Actually, she is not very interested in sex anytime, since
she was taught by her mother that sex was "dirty." The only
time she ever saw her parents making love, they were fully
clothed (hike up the skirt, dear - I'll just quickly unzip.)
Sometimes I wonder how we ever ended up with three children;
one is grown and on her own, the two boys (Ralph, 17 and
Trevor, 14) were with us on holiday. Because I travel
regularly, I have opportunity for other sexual outlets during
the year, but four plus weeks within close quarters with a
demanding uptight woman does not give you much opportunity to
develop alternatives.
I had some first class upgrade coupons, but at check-in
time was told there was only one seat available. Anne
immediately volunteered because of her "potential for a bad
back," and was seated in 3A. The boys and I were given 21K/L
and 22L. This was aisle and window seating in the 2-5-2
configuration, and the last two rows in the second section. I
took the single seat, and let Ralph and Trevor sit together for
the first ten-hour segment of the flight.
An attractive woman dressed in a loose sweater and very
tight blue jeans took the seat next to me. I could see that
Ralph was uncomfortable and maybe even a little jealous, since
he kept turning around to talk to me, but she was too old (29)
to be interested in him. She introduced herself as Christine,
"You can call me Chrissy." She was about five foot eight,
light brown (almost blond) long hair, a nice ass - firm and
high, breasts with an impact even through her shapeless
sweater, and obviously in good physical condition.
Chrissy was headed for Miami to pick up her belongings from
a recent divorce; she and her husband had been working together
on private yachts for eight years, and he had developed a
cocaine habit. When he would not seek help to end his drug
addiction, and more immediately after a close call with customs
in Australia last year, she decided then and there to split
from him, filed for divorce, stayed in Brisbane, and had just
been notified the divorce was final. In the meantime, she had
met another guy she wanted to stay with, and was going to Miami
to settle up the property and return to her new lover. This I
discovered during dinner conversation and over a few shared
glasses of wine. Looking into my eyes, she confided she was
"now free and ready for some excitement."
The movie started, the flight attendants went around the
cabin to lower all the shades, and Chrissy said, "I'd rather
talk, if it's OK with you; this movie is terrible." I had also
seen the movie and agreed. We spent the next two hours getting
to know each other better. Chrissy at one point said, "You
have terrific eyes, I get really turned on by eyes." We talked
about the kids, and when she asked if I was married and learned
about Anne in the front cabin, she thought it displayed selfish
behavior and then never mentioned my marital status again.
By now, the boys had fallen asleep, and just before the end
of the movie, Chrissy excused herself for a few minutes,
reached into the overhead bin for her carry-on (stretched long
enough to get my mind focused on her hips and legs in those
wonderful tight jeans,) and headed to the lavatory in the
back. When she returned, she was wearing loose-fitting
sweatpants, and when she asked if I minded if she lifted the
arm dividing the seats, I replied "Of course not!" By now I
had an idea of what she had in mind, because she had confided
during the movie that one of her greatest turn-ons was the risk
of discovery while having sex. "My husband was not a great
lover, but in the close confines of the boat it was always
exciting to fuck without anyone nearby knowing about it; I had
more orgasms from fucking near other people than from the sex
act itself." As she shared this with me, she was already
visibly breathing more quickly.
Chrissy and I arranged the blankets over both of us, now no
longer separated, and curled up like spoons in the otherwise
crowded seats. I started to give her a back rub, slowly
working over her muscles by now cramped from the first five
hours of the flight. She purred quietly, and after a while
squirmed her shapely ass on the seat, pushing it back into my
growing erection. With both hands I reached around under her
loose sweater, and fondled her globes, her nipples growing
firmer under my gentle stroking.
Chrissy reached back and with one hand released my belt,
then unbuckled and unbuttoned my pants. I whispered in her
ear, "How do you do that? I can't even do that with one hand,
and they're my pants." She laughed, and said, "Years of
practice; don't worry, it gets better." My hard-on sprang out
of my tight bikini briefs as she pulled the waistband forward,
and she whispered, "I'm glad you're not wearing boxer shorts, I
can't stand them."
Chrissy began to stroke my cock, now slightly oozing with
its own lubrication. She used the pre-come to help rotate her
fingers gently around the head, stroking it with ever firmer
pressure. I withdrew my hands from under her sweater to push
my pants down further, allowing me to slip the briefs down
below my swollen balls, which she now explored with her
questing hand. Lubricating her fingers even more with her
saliva, she alternately rubbed my balls and massaged the head
of my dick.
My hands were now free, and I hungrily reached forward for
her erect nipples, shortly afterward sliding my right hand down
her belly and slipping it under the waistband of her
sweatpants. She was wearing no panties underneath, and the
inside of the cotton sweats was already wet with her juices.
As I stroked her mound, her lubrication welcomed my fingers
into her warm wet cunt. Rubbing the juices on my fingers, I
began to circle her clitoris and then used my fingers to stroke
in and out of her pussy while my thumb pushed against her
swollen clit. She was breathing harder now, and could not stop
moving her ass around on the seat, first bucking her soaking
cunt against my right hand, then pushing her ass back against
my cock through the sweatpants.
Just then, the stewardess came down the aisle, paused
noticeably as she came up to our row, glared at me (me? why me?
there are two of us here, you know!), almost said something,
then apparently decided that since we were bothering nobody
else, she would keep moving. Thank God! While we were both
close to fully clothed at that time, there was little chance
she could do anything legally disastrous, but who needs the
embarrassment, or the hassle from the kids for that matter.
As the stewardess left, Chrissy whispered. "She knows
exactly what we are doing, and she's jealous! Now I want to
have your prick inside me. I'll keep quiet, but I need you to
fuck me now." With this, she lifted her ass off the seat and
slid her sweats down below her knees, then separated her legs
slightly and moved back so I could slide into her dripping
pussy from behind. I moved slowly in and out as she purred and
pushed back onto my cock quietly so we would not wake our
neighbors.
At the same time, I reached back around to stroke her
clitoris easily but steadily. The appearance of the stewardess
had startled me, and most of the urgency for release that had
built up from her stroking my hard-on had subsided, so it was a
nice, long, easy fuck, punctuated by her spasming in orgasm
three times before my cock pressure built up to the point of no
return. I came with the most excruciating pleasure I had felt
in my life (actually for the last month, but you know how easy
it is to lose perspective at the moment.) I felt like I
unleashed at least a pint of come into her already dripping
cunt. I sighed, and whispered' "Chrissy, it must have been
heaven that sent you to this seat. You don't know how much I
needed that."
She then turned around in the seat to sit normally, and
kissed me for the first time. "I needed it just as much as you
did; you're a terrific fuck, but on top of that it's the danger
that makes me come so much. Thanks for being here, I dreamed
that I'd be fucked silly on this trip. As we kissed, I told
her about my favorite turn-on. "What I like best is eating
pussy, but there is no room here for that. Would you like to
go to the back of the plane with me?"
"What do you mean? In the lavatory?" she asked.
"Yes. If we are reasonably cautious we can get in there
without causing an uproar," I replied.
"I've never done that before," Chrissy explained.
"There's a first time for everything," I said, and moved to
pull up my pants and buckle my belt. She thought about it for
a minute, and then said, "why not, let's try it!" She drew up
the sweatpants and tied the drawstring (I hadn't noticed there
was one before - must not have been tied.) Then she got up and
headed for the back of the plane, with me following directly
behind.
She entered the first lavatory, which was vacant (good
thing the flight was long, and everybody was still asleep.) I
slipped right in behind her before the flight attendants
noticed we were even there. As I closed the door, she turned
and we started to kiss passionately. She broke for a quick
query, "how do you do anything in this little space?" As I
untied the drawstring on her sweatpants, I said, "Just lift up
and sit on the sink, and let me taste your cunt."
Chrissy lifted, spread her legs, and I could see her cunt
lips were still swollen from her last orgasm. I gently tongued
her outer lips, occasionally swiveling my head to nip the
insides of her thighs, but always returning to circle her clit,
and as it swelled up, suck on it gently. There was no end to
the wetness; her own lubrication, supplemented by the enormous
load of come I had left in her pussy, dripped down both sides
of my chin onto the stainless steel sink surface and trailed
down her thighs.
After tonguing her into a few more orgasms, I realized how
hard I was getting again, and finally stood up, sliding her ass
slightly off the surface, and drove my cock into her again
while we exchanged extremely wet but tasty kisses, flavored by
both of our juices. Such a short time after the last fuck, and
she was sooo wet; this time it lasted at least twenty minutes,
both of us sighing and savoring the overwhelming sensations
coursing through our bodies. Finally, after a slow buildup
that I never wanted to end, I came again, not as much this
time, but she sensed it and started bucking hard just at the
same moment. The pleasure was so intense it was almost
painful.
The light came on to return to the cabin, and after a few
minutes we were able to adjust ourselves to some degree of
presentability to return to our seats. Just as we opened the
door, the same stewardess was looking right into my eyes. She
said angrily, "Please return to your seats and stay there. We
have some turbulence and the captain has turned on the seat
belt sign." I couldn't help but think that maybe we were the
cause of the turbulence, but then that's just my imagination
running away with me again.
As we settled in to the seats, Chrissy pushed the seat
divider down, saying, "I think everyone is waking up, let's not
embarrass your boys." The breakfast service was beginning, the
cabin lights were turned on, and we were again two strangers
who happened to be sitting next to each other on the plane.
The secret of our mile-high lovemaking was secure.
We exchanged addresses, but with her in Brisbane and me in
Boston it's not likely we'll ever meet again. Both of us
promised to use caution in contacting each other should the
opportunity arise, so our current SO would not be disturbed,
but also promised to get together if possible again.
I said goodbye to Chrissy at the seat, and went forward
with the unsuspecting boys to deplane.
As we got to the end of the ramp in the terminal, I asked
Anne, "How was your flight?"
"Great," she replied, "one of the most relaxing ever."
"Me too!"
yea, nobody ever remembers me, but when you get bored, and start reading the porn stories that pop up in the comments today, realize that i'm responsible.
A true story that really happend to me.
I had this really good friend named Dave who also had a friend
named Rusty. Well, Rusty had this really knockout girlfriend named
Candy. Dave is a real bullshitter and I didn't believe half of the
wild stories he told, so I just ignored his comments about how wild
Candy got when she got drunk. He told me how Rusty was the type of
guy that only wanted it about once or twice a week and Candy wanted it
once or twice an hour. Since she was a "good little girl" she
couldn't really cheat on Rusty, but if you got her drunk, she would do
anything and not feel guilty about it.
One day Dave told me he was going to prove to me how wild Candy
really was. He had arranged for us to meet her at the local Pizza Hut
for pizza and beer. When she met us I noticed that the dress she was
wearing was really unusual in that it was made almost exactly like a
raincoat, buttons down the front with a belt around the middle. I
also noticed a lot of cleavage and her shapely claves encased in
fishnet stockings.
We sat down and ordered our pizza and two pitchers of beer. When
the beer arrived, Candy said that she didn't want to drink any because
she didn't like the taste. Well, after our pizza arrived Candy gave
in and poured herself a glass of beer. When we were done with the
pizza, we were also done with the beer and Candy had only had one. We
soon ordered two more pitchers and convinced Candy that the only way
for her to drink with us was to "chug" each glass so she wouldn't
taste it so much. After "chugging" about six or seven glasses of
beer, Candy was being as sweet as her name. She had unbuttoned two of
the lower buttons on her dress so that she could mover her legs enough
to play footsie under the table with me. As we were leaving, Dave was
getting in the driver's side of the car and I was waiting for him to
unlock the passenger door when Candy called out to me. She was
standing in the center of the parking lot and when I turned she opened
up her dress and showed me a braless cutout corsett with garters and
stockings. Her nipples were about the size of a quarter and looked
like Hershey's Kisses in the cool evening air. Her bush was a light
strawberry blonde that looked like the hair was very thin or recently
trimmed. About then I realized that we were in the middle of a city
with about 100,000 people in it and it was still daylight at 8 P.M.
Dave unlocked the door and we got into the car. Nothing else happened
that night, but Candy and I became drinking buddies for several
months.
One evening about 4 months later Candy called me and invited me
and my bottle of rum over to her apartment for margaritas. I quickly
showered, dressed, hit the liquor store and was at her apartment in
about 20 minutes. When I got there I thought something was up because
Rusty was working night shift and Candy's roommate was out for the
rest of the night with her new beau. Candy made the mistake of
letting me make the margaritas and I loaded about a cup of rum into
each one of the drinks. After our third round Candy was feeling real
loose.
Our casual conversation suddenly turned sexy when candy asked if
I had liked her lingere that night at Pizza Hut. I said that I loved
lingere but had trouble finding women who were into it as much as I
was. When Candy heard that I loved lingere she offered to give me a
fashion show of her lingere collection. I quickly agreed and she
disappeared into the bedroom to change.
The first outfit she came out in really knocked my socks off. It
was a basic white bra with frilly lace accross the top edge of the
cups. The lace was cut just low enough to expose the top half of each
perky brown nipple. She was wearing white garters that rode perfectly
across her slender, full hips with four long, lacy straps leading down
to her white stockings. The stockings were the sheer white kind that
sparkle in the light and she was moving around alot to produce the
best possible effect with the little light available. She was wearing
white lace panties that were no more that two triangles of cloth held
together by lace straps. The front panel was transparent enough that
I could see her light bush and a hint of pussy lips. She really knew
what she was doing because she had put her panites on over the garters
so she could take off her panties without removing the garters.
The fashion show didn't get any further then because Candy sat
down next to me and started necking. Being fully clothed and in the
arms of this green-eyed, red-haired beauty while she was only clad in
her underwear was more than I could stand. I got up and started to
undress when Candy said "Let me do that for you." Candy undresses me
but made it a point not to touch me. She laid back on the couch and
handed me a vibrator that had magically appeared in her hand. "Do me
with this," she said. I took the vibrator from her and turned it on,
adjusting the speed to a very slow, humming speed. I started out on
her nipples and when they got good and hard I pushed the cups of her
bra down to expose them to my tongue. With one nipple in my mouth and
my left hand on the other, my right hand moved the vibrator around her
crotch and upper legs.
After about five minutes of playing this way I started to move
the vibrator into her cunt. I slowly tickled the outer lips of her
pussy with the tip of the vibrator and watched as her pussy unfolded
like a lovely flower. The vibrator was already slick with her pussy
juices that were leaking out of her like a lake draining so I pushed
it slowly up into her pussy. I kept pushing until all eight vibrating
inches were burried in her cunt. We moved into a sixty-nine position
so she could suck my cock and I could lick on her clit while I diddled
her with the vibrator.
I finally removed the vibrator from her pussy and decided to get
down to some serious cunt lapping. I shoved two fingers of my left
hand up into her pussy and started to dig around until I found the
magic spot. Once I had done this I sucked her clit into my mouth and
pushed up on the spot. Candy started squealing and bucking like she
was being electricuted and pussy juice coated my face and my arm down
to the elbow. Suddenly Candy stopped thrashing about and just lay
there breathing rapidly and deeply. Without any warning at all Candy
pissed all over the couch but didn't seem to notice or to wake up.
After about five minutes Candy woke up and was really embarassed about
peeing on the couch. Apparently she was totally knocked out by the
series of multiple orgasms. When she got her composure back she said,
"You can do anything you like."
When I heard this I was ecstatic. I first shoved my hard dick, I
still hadn't come yet, up her juicy cunt and then shoved a finger up
her asshole. After ten minutes of slow fucking and several orgasms by
Candy I lifted her legs over my shoulders. From this position I
withdrew my cock in a long slow stroke that made a popping sound when
it finally came out. Candy whimpered for me to put it back in her
when I pulled out but I had other ideas. I put my cunt juice
slickened dick right up to her anus and began to push. Candy was
obviously no stranger to anal sex because she relaxed and shoved right
back until my balls hit her ass. Then she started bucking and I
started pushing. This time the strokes were long, hard, and fast.
Candy grabbed the vibrator off the floor and pushed it into her cunt
with such savage force that I thought that she might hurt herself.
The vibrations were too much for Candy and she came twice real close
together then I was ready to come. Candy stopped me and told me to
come in her mouth so I withdrew my dick and, with her legs around my
thighs, shoved it into her mouth. With Candy sucking on the head of
my dick, one hand playing with my balls, and one finger of her other
hand up my asshole I came what seemed like gallons. Candy drank it
all down like a pro and then complimented me on my lovemaking.
I saw Candy regularly and more kinkily for several more months
and then she finally made a commitment to be true to Rusty and as far
as I know she hasn't broken it. She always knows that if she wants
anything in the way of sex she can call me.
It was hot and steamy as we arrived at the airport in Bris-
bane for the long journey home to Boston. This was the end of a
month-long campervan vacation in Australia, and I, for one, was
overjoyed to be heading back to some normalcy. For an entire
month my wife Anne (I call her "the queen") had avoided sex in
the campervan, or anywhere else for that matter, since "the
children are nearby." - The irony of her way of thinking will be
evident shortly.
Actually, she is not very interested in sex anytime, since
she was taught by her mother that sex was "dirty." The only time
she ever saw her parents making love, they were fully clothed
(hike up the skirt, dear - I'll just quickly unzip.) Sometimes I
wonder how we ever ended up with three children; one is grown and
on her own, the two boys (Ralph, 17 and Trevor, 14) were with us
on holiday. Because I travel regularly, I have opportunity for
other sexual outlets during the year, but four plus weeks within
close quarters with a demanding uptight woman does not give you
much opportunity to develop alternatives.
I had some first class upgrade coupons, but at check-in time
was told there was only one seat available. Anne immediately
volunteered because of her "potential for a bad back," and was
seated in 3A. The boys and I were given 21K/L and 22L. This was
aisle and window seating in the 2-5-2 configuration, and the last
two rows in the second section. I took the single seat, and let
Ralph and Trevor sit together for the first ten-hour segment of
the flight.
An attractive woman dressed in a loose sweater and very tight
blue jeans took the seat next to me. I could see that Ralph was
uncomfortable and maybe even a little jealous, since he kept
turning around to talk to me, but she was too old (29) to be
interested in him. She introduced herself as Christine, "You can
call me Chrissy." She was about five foot eight, light brown
(almost blond) long hair, a nice ass - firm and high, breasts
with an impact even through her shapeless sweater, and obviously
in good physical condition.
Chrissy was headed for Miami to pick up her belongings from a
recent divorce; she and her husband had been working together on
private yachts for eight years, and he had developed a cocaine
habit. When he would not seek help to end his drug addiction,
and more immediately after a close call with customs in Australia
last year, she decided then and there to split from him, filed
for divorce, stayed in Brisbane, and had just been notified the
divorce was final. In the meantime, she had met another guy she
wanted to stay with, and was going to Miami to settle up the
property and return to her new lover. This I discovered during
dinner conversation and over a few shared glasses of wine.
Looking into my eyes, she confided she was "now free and ready
for some excitement."
The movie started, the flight attendants went around the
cabin to lower all the shades, and Chrissy said, "I'd rather
talk, if it's OK with you; this movie is terrible." I had also
seen the movie and agreed. We spent the next two hours getting
to know each other better. Chrissy at one point said, "You have
terrific eyes, I get really turned on by eyes." We talked about
the kids, and when she asked if I was married and learned about
Anne in the front cabin, she thought it displayed selfish behav-
ior and then never mentioned my marital status again.
By now, the boys had fallen asleep, and just before the end
of the movie, Chrissy excused herself for a few minutes, reached
into the overhead bin for her carry-on (stretched long enough to
get my mind focused on her hips and legs in those wonderful tight
jeans,) and headed to the lavatory in the back. When she re-
turned, she was wearing loose-fitting sweatpants, and when she
asked if I minded if she lifted the arm dividing the seats, I
replied "Of course not!" By now I had an idea of what she had in
mind, because she had confided during the movie that one of her
greatest turn-ons was the risk of discovery while having sex.
"My husband was not a great lover, but in the close confines of
the boat it was always exciting to fuck without anyone nearby
knowing about it; I had more orgasms from fucking near other
people than from the sex act itself." As she shared this with
me, she was already visibly breathing more quickly.
Chrissy and I arranged the blankets over both of us, now no
longer separated, and curled up like spoons in the otherwise
crowded seats. I started to give her a back rub, slowly working
over her muscles by now cramped from the first five hours of the
flight. She purred quietly, and after a while squirmed her
shapely ass on the seat, pushing it back into my
growing erection. With both hands I reached around under her
loose sweater, and fondled her globes, her nipples growing firmer
under my gentle stroking.
Chrissy reached back and with one hand released my belt, then
unbuckled and unbuttoned my pants. I whispered in her ear, "How
do you do that? I can't even do that with one hand, and they're
my pants."
She laughed, and said, "Years of practice; don't worry, it
gets better." My hard-on sprang out of my tight bikini briefs as
she pulled the waistband forward, and she whispered, "I'm glad
you're not wearing boxer shorts, I can't stand them."
Chrissy began to stroke my cock, now slightly oozing with its
own lubrication. She used the pre-come to help rotate her fin-
gers gently around the head, stroking it with ever firmer pres-
sure. I withdrew my hands from under her sweater to push my
pants down further, allowing me to slip the briefs down below my
swollen balls, which she now explored with her questing hand.
Lubricating her fingers even more with her saliva, she alternate-
ly rubbed my balls and massaged the head of my dick.
My hands were now free, and I hungrily reached forward for
her erect nipples, shortly afterward sliding my right hand down
her belly and slipping it under the waistband of her sweatpants.
She was wearing no panties underneath, and the inside of the
cotton sweats was already wet with her juices. As I stroked her
mound, her lubrication welcomed my fingers into her warm wet
cunt. Rubbing the juices on my fingers, I began to circle her
clitoris and then used my fingers to stroke in and out of her
pussy while my thumb pushed against her swollen clit. She was
breathing harder now, and could not stop moving her ass around on
the seat, first bucking her soaking cunt against my right hand,
then pushing her ass back against my cock through the sweatpants.
Just then, the stewardess came down the aisle, paused notice-
ably as she came up to our row, glared at me (me? why me? there
are two of us here, you know!), almost said something, then
apparently decided that since we were bothering nobody else, she
would keep moving. Thank God! While we were both close to fully
clothed at that time, there was little chance she could do any-
thing legally disastrous, but who needs the embarrassment, or the
hassle from the kids for that matter.
As the stewardess left, Chrissy whispered. "She knows exact-
ly what we are doing, and she's jealous! Now I want to have your
prick inside me. I'll keep quiet, but I need you to fuck me
now." With this, she lifted her ass off the seat and slid her
sweats down below her knees, then separated her legs slightly and
moved back so I could slide into her dripping pussy from behind.
I moved slowly in and out as she purred and pushed back onto my
cock quietly so we would not wake our neighbors.
At the same time, I reached back around to stroke her clito-
ris easily but steadily. The appearance of the stewardess had
startled me, and most of the urgency for release that had built
up from her stroking my hard-on had subsided, so it was a nice,
long, easy fuck, punctuated by her spasming in orgasm three times
before my cock pressure built up to the point of no return. I
came with the most excruciating pleasure I had felt in my life
(actually for the last month, but you know how easy it is to lose
perspective at the moment.) I felt like I unleashed at least a
pint of come into her already dripping cunt. I sighed, and
whispered' "Chrissy, it must have been heaven that sent you to
this seat. You don't know how much I needed that."
She then turned around in the seat to sit normally, and
kissed me for the first time. "I needed it just as much as you
did; you're a terrific fuck, but on top of that it's the danger
that makes me come so much. Thanks for being here, I dreamed
that I'd be fucked silly on this trip. As we kissed, I told her
about my favorite turn-on. "What I like best is eating pussy,
but there is no room here for that. Would you like to go to the
back of the plane with me?"
"What do you mean? In the lavatory?" she asked.
"Yes. If we are reasonably cautious we can get in there
without causing an uproar," I replied.
"I've never done that before," Chrissy explained.
"There's a first time for everything," I said, and moved to
pull up my pants and buckle my belt. She thought about it for a
minute, and then said, "why not, let's try it!" She drew up the
sweatpants and tied the drawstring (I hadn't noticed there was
one before - must not have been tied.) Then she got up and
headed for the back of the plane, with me following directly
behind.
She entered the first lavatory, which was vacant (good thing
the flight was long, and everybody was still asleep.) I slipped
right in behind her before the flight attendants noticed we were

web server .. and then make sure that your webmail client supports connecting to remote hosts. most webmail applications use IMAP or POP3, and in those, you can specify WHICH SERVER you wish to connect to... in this case, a user connecting to the web front end would allow the webserver to connect to the mail server via IMAP/POP3, and the mail server wouldnt need any traffic to 80 at all.
heh, even the meta-trolls get modded up these days ... sad, very very sad.
So, they've got 7000 users on a brand new redhat framework, my questions is, do they, like me, possess
WARM BAWLS
?
You are truly stupid. Do you have no idea what's going on? Do you not realize that the site is /.'ed? This is the complete opposite of "offtopic", it's, by definition, on topic, as it is a MIRROR FUCKING COPY of what nobody else can see.
this has been proposed before, and they have a good reason for NOT caching news stories: it takes control of the story out of the hands of the original poster, making it unable for the person to shut down their site if they want privacy, and making slashdot responsible for posting potentially illegal material (remember all the DeCSS things linked to in the past?) ... they cant cache it, but they should at least warn the webmasters before posting it. Typically /.'ing is just a misconfigured (max processes = 15 by default, right?) apache server, especially in a university setting.
Demonstrations 04 & 05
Flammable vapours
Continuing the theme of combustion this is an attempt to model an incident that occurred in a small garage local to where MH lives in Sheffield. In these spectacular experiments dihydrogen, diethyl ether and alcohol are burned.
Liquids that vaporise easily at ambient temperature to form heavy vapours pose particular hazards during handling e.g. when transferring from one container to another, or when spilled.
Petrol is the most common of these fluids and serious accidents have occurred during handling due to flashback from sources of ignition often at considerable distance away. Because the heavy vapour spreads along the ground it does not readily defuse into the air and become diluted below its explosive/flammable limit so the, even outdoors, it can be very dangerous. People attempting to kindle garden fires or BBQ's with petrol have all too often been engulfed in flames due to the spread of the vapour beyond the intended area. Similarly liquid petroleum gas (LPG) has also caused appalling accidents when 'fire balls' have formed due to the ignition of dense clouds of the gas. Butane has a density of more than twice that of air.
These experiments attempt to simulate, and so demonstrate, this phenomenon. Diethyl ether is used because it has a combination of high vapour pressure (440mm Hg at 20C) and density (2.55 {air = 1}) and has been responsible for many accidents in the laboratory and the chemical industry where it is often used as a solvent in chemical processes.
In the first demonstration a length of extruded aluminium angle is set up to form a channel along the length of the lecture bench (some five meters) such that one end is at bench level and the other some 150cm higher. In the video this is said to represent the floor of a garage (set sloping in order to reduce the experimentation time) and a wad of burning cotton wool soaked with a little alcohol at the lower end is said to represent someone welding (a source of ignition). Balloons are attached at the high end. These are filled with hydrogen gas except the yellow one to which a little oxygen had been added in addition to the hydrogen (the story line has these to emphasise the effect of a leaking fuel tank exploding). Sufficient diethyl ether wars added to the high end of the channel (representing a petrol leak) such that it was all vaporised by the time it had reached about half way down. The heavy vapour continued down the remaining 2.5m and was ignited on reaching the 'welder'. The thunderous sound of the explosion it impossible to reproduce from the video but some compensation is afforded if the exploding balloons are played back frame by frame.
The speed of the (defusion) flame front along the channel was quite slow due to the lack of mixing of the vapour with the air. In reality air movement, particularly if it were outdoors, would pre mix some of the ether and air. The second experiment attempts to simulate this. The storyline here is that the space enclosed by the Perspex safety screens represents a laboratory and the candle represents a Bunsen burner. Diethyl ether (15ml) is spilled on the floor a metal tray and left to evaporate. Later a small electric fan is started to create a draught and so mix the vapour and the air. When this pre-mixture reaches the source of ignition the resulting conflagration is very rapid and if were much larger or confined, an explosion would occur. See also experiments 7 and 15a.
This is one occasion when seeing it in real time is less impressive than the series of single frames, there are 25 each second. The series of diagonal stripes from top left to bottom right, to be seen on one of the frames, are vertical, or near vertical, oscillations (pressure regions). They are slanting because of the way the image is scanned by the camera, left to right, top to bottom.
By using video frames as units of time (each represents 40ms) the relative velocities of the near diffusion flame-front and the pre-mixed flame-front can be, roughly, determined. Since the same synchronisation pulse as received by all three cameras any combination could be used for this purpose. I used camera three for the (near diffusion) flame on the channel and counted the number of frames that showed it passing the front of the safety screen enclosure. The images on the video are from another camera and are not useful for this. I used frames from camera one for the pre-mixed flame-front which is the one use for the video at that time. I got the following results:
Number of frames taken for the 'diffusion' flame to traverse the enclosure front = 17 (= 680ms)
Number of frames taken for the pre-mixed flame to traverse the enclosure front = 7 (= 280ms)
Relative velocities 680/280 = 2.4.
So the pre-mixed flame travelled about two and a half time faster than the diffusion flame. However, until the flame was bounded by the walls of the enclosure the increase in volume was 2.43 faster i.e. about 14 times!
HAZARDS
The main hazards are exemplified by the demonstration itself. . Diethyl ether has a high vapour pressure (440mm Hg at 20C) and density (2.55 {air = 1}) and a low auto ignition temperature (not flash point!) of between 180 and 190C. Air/ether mixtures containing >1.85% v/v of diethyl ether vapour are constitute an explosive hazard.
Explosive peroxides (ethylidene peroxide polymers') may be formed on exposure to air and light, and particularly when evaporated to dryness. These peroxides have been known to form around the stoppers of container of diethyl ether that have been left unopened for long periods. Although not relevant to this experiment it is worth pointing out that ether is a good electrical insulator and when very dry (saturated ether contains 1.2% water at 20C), shaking etc. can produce sufficient static electricity to cause ignition of the vapour.
Diethyl ether is mildly irritating to skin and mucous membranes. Inhalation of high concentrations causes narcosis1.
Hydrogen gas is very flammable and yields explosive mixtures with air. The stoichiometric mixture should be avoided because the explosion is too loud. The audience should be, at least, three meters from the balloons.
DISPOSAL
Immediately after the explosion a careful check should be made to make sure that no debris from the balloons are burning2. I have performed this demonstration over 70 times (>280 balloons) and have not found this to happen but one should be aware that it could! The cotton wool should be extinguished by covering with a watch glass and left to cool.
