Evanescent Lasers to Speed Up Data Transmission
Roland Piquepaille writes "Researchers at UC Santa Barbara (UCSB) have built the world's first mode-locked silicon evanescent laser. But what is an 'evanescent' laser? It is a step toward 'combining lasers and other key optical components with the existing electronic capabilities in silicon.' In other words, this research work will provide a way to integrate optical and electronic functions on a single chip. As these evanescent lasers can produce stable short pulses of laser light, they will be useful for many optical applications, such as high-speed data transmission or highly accurate optical clocks."
But every now and then, right around dusk, I'll look out my back window as the sun falls slowly to sleep. And I'll chuckle a little when I catch myself. I just can't stop believing that Negroes exist!
I never doubted the existence of Negroes as a kid. My parents smiled knowingly and said nothing. But at night, lying in bed, I could imagine that Negroes really might be chirping and fluttering across the nearby countryside, scouring the foliage for the secret ingredients of Negro Stew.And of course I believed the legend that a young child, pure of heart, could make a Negro appear. If I was a good boy, perhaps I might see one tip his top hat and give me a wink!
It was Mark Twain's classic novel on Negro life, Yassuh, Massuh Clements, Whatevuh Yuh Say, Suh, that hatched an ill plan of mine to actually see a Negro in person. In that immortal piece of Americana, Twain recounts the old legend that a young lad can summon a Negro. He must stand outside at dusk, face southeast, hold a tooth that has just fallen out, and sing:
Cah Loo, Cah Lee, Tra Loo, Tra Ley,
A Negro song today!
Come hear my call, come one and all,
Tra Lee La Negro, hey!
If ye be keen to come along
And sing the magic Negro songs,
Then Tra Lee La, Tra True La Ley,
T'will be a Negro day!
If all goes well, the young boy will hear a voice singing in the distance:
A taste of stew, and Negro Pie,
Oh who will break my fast with me?
For me it is a weary life,
But I will sup with thee.
For tales, I'll tell you of a lass,
My Negress love at distant shore.
We'll sing beneath an apple tree,
A merry Negroling and thee,
Until the dawn is born.
And, after suddenly appearing with a flash of light and burst of smoke, the Negro will exchange the tooth for a bag of silver dimes.
Well, when I was seven, I was ready to try it out. Sneaking out of my bedroom, I crept down the stairs and into the backyard. I was certain that I would actually see a Negro! What would he be like? Would he be mean or friendly? Would he show me the magic sword used to fend off the Irish?
After singing into the night as loudly as I dared, I stood with an expectant grin. The grass was soft under my pyjama feet. There seemed to be a sparkle in the air! But after several hours of waiting, I slumped with disappointment. No Negroes for me. My father rushed downstairs upon hearing me come in. At first he was worried, but his concerned frown turned into a gentle smile when he heard what I had been up to.
"Son," he said, somberly. "There are no such things as Negroes."
A little bit of my childhood died that day. But not completely. Whenever the dusk falls on a clear summer day, I look out to the southeast and dream of a bite of Negro Pie.
I used to find Slashdot delightful,
but my feelings of late are more spiteful;
my comments sarcastic
the iconoclastic

Data (1) (1)
The head of the Galactic
Confederation (76 planets around
larger stars visible from here)
(founded 95,000,000 yrs ago, very space opera)
solved overpopulation (250 billion
or so per planet) -- 178 billion
average) by mass implanting.
He caused people to be brought to
Teegeeack (Earth) and put an H Bomb
on the principal volcanoes (Incident 2)
and then the Pacific area ones
were taken in boxes to Hawaii
and the Atlantic Area ones to
Las Palmas and there "packaged."
His name was Xenu. He used
renegades. Various misleading
data by means of circuits etc.
were placed in the implants.
When through with his crime Loyal Officers
(to the people) captured him
after 6 years of battle
and put him in an electronic
mountain trap where he still
is. "They" are gone. The place (Confed.)
has since been a desert.
File this with fusion, peace in the mid East, and me getting laid.
