Nano Smiley Face made from DNA!

DNA_smiley.jpg

“A nanotechnologist has created the world’s smallest and most plentiful smiley, a tiny face measuring a few billionths of a metre across assembled from strands of DNA. Dr Paul Rothemund at the California Institute of Technology can make 50 billion smileys, each a thousand times smaller than the diameter of a human hair, with his technique.”

Burning visible images onto CD-Rs with data (beta)

“By carefully choosing the right 1s and 0s to burn to a CD, it is possible to burn visible images on normal CD-Rs. These images rely on the fact that the 1s and 0s created by pits in the CDs surface reflect light differently…”

This is just insane!

There are even MATLAB programs etc on the website to help you do the same!
What an innovative idea! Remember, this is nothing to do with the Lightscribe kind of stuff… since Lightscribe requires special media…

Cometh Holi, cometh the Ho(o)ligans!

Holi, the Indian festival of colours is quite a one-of-its-kind festival, commemorating both the destruction of Holika, as well as the burning of Manmatha, symbolising desire/lust. Read more on the mythology on wikipedia: http://en.wikipedia.org/wiki/Holi

However, the colour-throwing, as fun as it may be, has often been quite a nuisance, since a lot of people are quite paranoid about the synthetic colours, their adverse effects on the skin/eyes, leave alone merely getting very very dirty! A lot of hooliganistic behaviour has often been seen in various cities, Delhi I think, being particularly notorious, and Bombay too, uncharacteristically.

Even in an elite place like IISc, there is too much of hooliganism to believe or bear. The messes were messed up, as were several corridors. And after all this, this was probably the cleanest of the last three Holi’s I have seen here. The first one was a veritable disaster with colourful handprints on the brand new hostel’s walls. The next time, not even departments were spared, with colour strewn all over. This time, being a working day, the damage was contained I should guess. People walking into messes with colours strewn all over is never an endearing sight, more so if they take food — from the perspective of everyone’s health and hygiene! — dirtying chairs and the food alike.
The bottomline is that the celebration of the victory over the Asuras, of Prahlada being saved is celebrated indeed in Asura fashion. Some serious soul-searching needs to be done by these people. No one objects to peaceful enjoyment. Why drag in someone who is not interested? (Curiously, I say all this even though I’ve had to suffer nothing!) Why is there a failure to merely respect each other’s preferences?

Google News gets foiled by 15-year old Vandetta

Tom Vandetta found an article that explained how to fool Google’s news system by writing fake press releases. He then decided to see what would happen if he submitted a fake Google press release claiming the 15-year old New Jersey student was Google’s youngest employee.

The press release was issued through the free service I-Newswire and contained a number of spelling mistakes. Short and to the point, the release, which appeared to have been sent by a Google spokesperson Sonya Johnson (who’s actually existence is unconfirmed and is assumed to be imaginary), read:

“(I-Newswire) – 15 year old student, Tom Vendetta has been hired by search engine giant Google Inc. The student will receive a lowered salary, which will be placed into a bank account for future education, said Google CEO Larry Page. When asked what role Vendetta will play at the Tech Giant’s offices, Page said he wouldnt have a role at the Main Offices. Instead he would work from his home in the New Jersey suburbs. Vendetta will be incharge of working with recent security flaw’s in Google’s beta e-mail service, “Gmail”. Google said they first found out about him when they discovered the student’s blog, at http://tomvendetta.be. The media giant said they looked forward to working with Vendetta’s expertise in JavaScript and AJAX.”

A few hours after posting the fake press release, Vandetta logged into the news search tool Digg after receiving an automated email from MAKEBot (Digg’s Spider), to find his practical joke had become a credible international tech story. Google was even displaying reference to the press release in Google News and at in the news results placed above search results relating to Google employment or hiring. According to his confessional blog posting, “At that moment, I felt my stomach knot up and my heart drop. I knew exactly what happened and knew that I would end up regretting posting that.”

The prank has made Vandetta temporarily famous. His Gmail account received almost 400 emails in the first few hours. Vandetta has since had to open new Gmail and MySpace accounts. His parents are changing their phone number and he is working to re-establish a workable online identity. On the brighter side, he has received a few emails from Google employees assuring him he has not dashed his dreams of one day working for Google, as he thought he might have.

π day

π = 3.14159 26535 89793 23846 26433 …

3.14 = March 14 happens to be pi-day every year. Curiously enough, it also happens to be Einstein’s birthday!

http://www.angio.net/pi/bigpi.cgi gives you a search engine to search for digits of π. For example, a search for 15081947 gives

“The string 15081947 occurs at position 604,341 counting from the first digit after the decimal point. The 3. is not counted.

The string and surrounding digits:

99538905839657483550 15081947 01003364946075415680″

If you are quite crazy about π, you might want to pick up this geeky T-shirt (I created something very similar on photoshop, yet to print it!) from thinkgeek.

Indeed an enigmatic constant!

Further, last April 1, google came up with this fantastic page:

Quench your thirst for knowledge.

At Google our mission is to organize the world’s information and make it useful and accessible to our users. But any piece of information’s usefulness derives, to a depressing degree, from the cognitive ability of the user who’s using it. That’s why we’re pleased to announce Google Gulp (BETA)™ with Auto-Drink™ (LIMITED RELEASE), a line of “smart drinks” designed to maximize your surfing efficiency by making you more intelligent, and less thirsty.

Think fruity. Think refreshing.

Think a DNA scanner embedded in the lip of your bottle reading all 3 gigabytes of your base pair genetic data in a fraction of a second, fine-tuning your individual hormonal cocktail in real time using our patented Auto-Drink™ technology, and slamming a truckload of electrolytic neurotransmitter smart-drug stimulants past the blood-brain barrier to achieve maximum optimization of your soon-to-be-grateful cerebral cortex. Plus, it’s low in carbs! And with flavors ranging from Beta Carroty to Glutamate Grape, you’ll never run out of ways to quench your thirst for knowledge.

How to get Gulped?
You can pick up your own supply of this “limited release” product simply by turning in a used Gulp Cap at your local grocery store. How to get a Gulp Cap? Well, if you know someone who’s already been “gulped,” they can give you one. And if you don’t know anyone who can give you one, don’t worry – that just means you aren’t cool. But very, very (very!) soon, you will be.

Further, last August, ONION came up with this hilarious article, spoofing the google enthusiasm:

Google Purge

Executives at Google, the rapidly growing online-search company that promises to “organize the world’s information,” announced Monday the latest step in their expansion effort: a far-reaching plan to destroy all the information it is unable to index.

“Our users want the world to be as simple, clean, and accessible as the Google home page itself,” said Google CEO Eric Schmidt at a press conference held in their corporate offices. “Soon, it will be.”

The new project, dubbed Google Purge, will join such popular services as Google Images, Google News, and Google Maps, which catalogs the entire surface of the Earth using high-resolution satellites.

As a part of Purge’s first phase, executives will destroy all copyrighted materials that cannot be searched by Google.

“A year ago, Google offered to scan every book on the planet for its Google Print project. Now, they are promising to burn the rest,” John Battelle wrote in his widely read “Searchblog.” “Thanks to Google Purge, you’ll never have to worry that your search has missed some obscure book, because that book will no longer exist. And the same goes for movies, art, and music.”

“Book burning is just the beginning,” said Google co-founder Larry Page. “This fall, we’ll unveil Google Sound, which will record and index all the noise on Earth. Is your baby sleeping soundly? Does your high-school sweetheart still talk about you? Google will have the answers.”

Google executives oversee the first stage of Google Purge:
