Yale Scientists Explain Why Computers Crash But We Don’t

The hierarchical organization of the transcriptional regulatory network of bacterium E. Coli, left, shows a pyramidal structure compared to the Linux call graph, which has many more routines controlling few generic functions at the bottom.
The hierarchical organization of the transcriptional regulatory network of bacterium E. Coli, left, shows a pyramidal structure compared to the Linux call graph, which has many more routines controlling few generic functions at the bottom.

Yale scientists recently revealed why living organism malfunction less than computers, after doing a study on it. The Yale team compared the evolution of organisms and computer operating system. They analyzed the control networks in both Linux operating system as well as bacterium Escherichia coli.

They found out that both E coli and the Linux networks are arranged in hierarchies, but with some notable differences in how they achieve operational efficiencies. There was differences in the molecular network arrangement. When its arranged in a pyramid in bacteria, its inverted pyramid in Linux operating system. There were only limited number of master regulatory genes at the top that control a broad base of specialized functions, which act independently in bacteria. But taking the case of Linux operating system, there were many different top-level routines controlling few generic functions at the bottom of the network. According to Gerstein, this is because software engineers tend to save money and time by building upon existing routines rather than starting systems from scratch. He also added that operating system is more vulnerable to breakdowns because even simple updates to a generic routing can be very disruptive. To compensate this, generic routines need to be fine-tuned periodically by designers.

A Single Molecule Computes Thousands of Times Faster than Your PC

Computing with Iodine

A demo of a quantum calculation carried out by Japanese researchers has yielded some pretty mind-blowing results: a single molecule can perform a complex calculation thousands of times faster than a conventional computer.

A proof-of-principle test run of a discrete Fourier transform — a common calculation using spectral analysis and data compression, among other things — performed with a single iodine molecule transpired very well, putting all the molecules in your PC to shame.

Using quantum interference – the vibrations of the atoms themselves – the team was able to run the complete discrete Fourier transform extremely quickly by encoding the inputs into an optically tailored vibrational wave packet which is then run through an excited iodine molecule whose atomic elements are oscillating at known intervals and picked up by a receiver on the other side. The entire process takes just a few tens of femtoseconds (that’s a quadrillionth of a second). So we’re not just talking faster data flow or processing here; these are speeds that are physically impossible on any kind of conventional electronic device.

But don’t trade in your conventional computing power just yet. Like other quantum information platforms, molecular computing is in its infancy; we understand some of its mechanisms, but it’s difficult to execute and there are still a lot of unknowns. Further, researchers aren’t quite sure how they could integrate such technology into something that works the way we’re used to our computers working.
Still, the very fact that researchers were able to pull off a calculation at such speeds shows just how big of an impact molecular calculations could have on the science of computing.

The Road Not Taken by Robert Frost

Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I-
I took the one less traveled by,
And that has made all the difference.

i carry your heart with me by E. E. Cummings

i carry your heart with me(i carry it in
my heart)i am never without it(anywhere
i go you go,my dear; and whatever is done
by only me is your doing,my darling)
i fear
no fate(for you are my fate,my sweet)i want
no world(for beautiful you are my world,my true)
and it’s you are whatever a moon has always meant
and whatever a sun will always sing is you

here is the deepest secret nobody knows
(here is the root of the root and the bud of the bud
and the sky of the sky of a tree called life;which grows
higher than the soul can hope or mind can hide)
and this is the wonder that’s keeping the stars apart

i carry your heart(i carry it in my heart)

Letter to God!

Letter to God
A little boy wanted Rs.50 very badly and prayed for weeks, but nothing happened.
Finally he decided to write God a letter requesting the Rs.50.
When the postal authorities received the letter addressed to God, INDIA, they decided to forward
it to the President of the India as a joke.
The President was so amused, that he instructed his secretary to send the little boy Rs.20.
The President thought this would appear to be a lot of money (Rs.50) to a little boy,
and he did not want to spoil the kid.
The little boy was delighted with Rs…20, and decided to write a thank you note to God,
which read:
“Dear God: Thank you very much for sending the money.
However, I noticed that you sent it through the Rashtrapati Bhavan(President House) in New Delhi , and those donkeys deducted Rs.30 as tax ……. “

Lord Alfred Tennyson-Ulysses

It little profits that an idle king,
By this still hearth, among these barren crags,
Matched with an aged wife, I mete and dole
Unequal laws unto a savage race,
That hoard, and sleep, and feed, and know not me.

I cannot rest from travel: I will drink
Life to the lees: all times I have enjoyed
Greatly, have suffered greatly, both with those
That loved me, and alone; on shore, and when
Through scudding drifts the rainy Hyades
Vest the dim sea: I am become a name;
For always roaming with a hungry heart
Much have I seen and known; cities of men
And manners, climates, councils, governments,
Myself not least, but honoured of them all;
And drunk delight of battle with my peers;
Far on the ringing plains of windy Troy.
I am part of all that I have met;
Yet all experience is an arch wherethrough
Gleams that untravelled world, whose margin fades
For ever and for ever when I move.
How dull it is to pause, to make an end,
To rust unburnished, not to shine in use!
As though to breath were life. Life piled on life
Were all to little, and of one to me
Little remains: but every hour is saved
From that eternal silence, something more,
A bringer of new things; and vile it were
For some three suns to store and hoard myself,
And this gray spirit yearning in desire
To follow knowledge like a sinking star,
Beyond the utmost bound of human thought.

This is my son, mine own Telemachus,
To whom I leave the scepter and the isle—
Well-loved of me, discerning to fulfill
This labour, by slow prudence to make mild
A rugged people, and through soft degrees
Subdue them to the useful and the good.
Most blameless is he, centered in the sphere
Of common duties, decent not to fail
In offices of tenderness, and pay
Meet adoration to my household gods,
When I am gone. He works his work, I mine.

There lies the port; the vessel puffs her sail:
There gloom the dark broad seas. My mariners,
Souls that have toiled, and wrought, and thought with me—
That ever with a frolic welcome took
The thunder and the sunshine, and opposed
Free hearts, free foreheads—you and I are old;
Old age had yet his honour and his toil;
Death closes all: but something ere the end,
Some work of noble note, may yet be done,
Not unbecoming men that strove with Gods.
The lights begin to twinkle from the rocks:
The long day wanes: the slow moon climbs: the deep
Moans round with many voices. Come, my friends,
‘Tis not too late to seek a newer world.
Push off, and sitting well in order smite
The sounding furrows; for my purpose holds
To sail beyond the sunset, and the baths
Of all the western stars, until I die.
It may be that the gulfs will wash us down:
It may be we shall touch the Happy Isles,
And see the great Achilles, whom we knew.
Though much is taken, much abides; and though
We are not now that strength which in the old days
Moved earth and heaven; that which we are, we are,
One equal-temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.

automate graphical user interface…how???

Those who are fed-up doing the same things a thousand times thinking that using the mouse, moving the cursor over the right place, selecting the right options can be done only manually can sit back and relax now. It too has got a solution. Surprised…,huh??? I’m not joking and also you can trust fully, its an invention from the real MIT(Massachussets Institute of Technology).
Suppose you want to do the same thing on every login, don’t worry just write a script once and you just need to run it on the login time.
Happy now? At least some of you might have thought that it would be better if could automate GUIs; to all those, dont worry anymore MIT has a solution now. Dont worry you have to learn a new language for it. Its just python which is very easy to learn and also you dont have to worry saying you having to code all the stuff manually where to click!!!!!!!Thats where the real fun begins…
There is also option to select the area where to click with your mouse…Now i’m sure you’re realy impressed.
Logon to Sikuli.org and see the videos they provide and read more on it…

To all Engineers:Get inspired from what those MITians have achieved and come up with new amazing inventions for the world

to all keralites…

Today, 24th january 2010. I had a glimpse on Malayala Manorama news paper. I was shocked to read the news of a 15 year old girl, Aarya, who lost her foot in an accident in Kayamkulam. She is from Muthukulam which is very near to my house. She stepped down from a bus at civil station and was walking to KSRTC bus station to go to KPAC junction. The car then came fast out of control and its tyre went over her right foot. A driving student drived the car. The girl had to cut off her foot. Now think my keralites… where is our KERALA going? what is this girl gonna do without her foot which GOD gave her? Don’t our govt have any resposibility to check on road accidents? We pay tax for living here, for using the roads, and its our tax money the govt use to pay for govt officials. But police officials forget this and come to road to ensure everyone uses helmet and everyone follow traffic rules only when they need some money to party with their colleagues. I would say unless we react this is gonna repeat for ever…
