'Self-destructing' Snapchat and Facebook Poke messages can actually be copied, but that shouldn't be a surprise. Protect yourself.

Image
The current kerfuffle over Snapchat and Facebook's 'self-destructing' videos actually being saveable is a great thing to see, because it reminds people of why they should never sext unless they want their junk splattered all over whatever site the porn impresario and professional jerk Hunter Moore is running this week. Repeat after me: Anything you put on the Internet is potentially public. P.S. Cell phones count as the Internet. This is pretty much a fixed rule. Digital data can be copied. If it's only on your own computer, you have control of it. But as soon as it's shared with anyone — anyone — that person can copy and spread it. Or, as the always witty Chris Davies said on Twitter, "Keep putting your genitals in front of people & they'll inevitably go viral." Oh, Those TeenagersTeenagers overlook this because teenagers are actually clinically brain damaged. They're biologically programmed to ignore risk and act on emotion. So I can excuse …

100-year-old deathbed dreams of mathematician proved true

Image
Srinivasa Ramanujan (Emory University) While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right. "We've solved the problems from his last mysterious letters. For people who work in this area of math, the problem has been open for 90 years," Emory University mathematician Ken Ono said. 'For a brief window of time, he lit the world of math on fire.' - Emory University mathematician Ken Ono Ramanujan, a self-taught mathematician born in a rural village in South India, spent so much time thinking about math that he flunked out of college in India twice, Ono said. But he sent mathematicians letters describing his work, and one of the most preeminent ones, English mathematician G. H. Hardy, recognized the Indian boy's genius and invited him to Cambridge University in England …

Image
Games can be both a welcome and an annoying diversion on Facebook, the world's most popular online social network. This year, Facebookcrossed a big milestone - reaching 1 billion active users. Game companies such as "FarmVille" creator Zynga and Rovio Entertainment of "Angry Birds" fame seek to tap into that vast base of users to gain more players for their games. 

This week, Facebook issued a list of the 25 top-rated games that launched on Facebook in 2012. The company says the rankings are based on user ratings and engagement with the games. It's the same methodology that Facebook uses to rank apps in its App Center. 

Some of the games are played on Facebook's website, while others are only on Apple's iOS or Google's Android devices using Facebook's app. 

Here's the list: 

1. "SongPop" (by FreshPlanet, on Facebook.com, iOS and Android)

Image
Delhi may soon become the first city in the country to have global retail chains like Walmartand Tesco, with the city government all set bring a bill in the Winter session of assembly beginning Tuesday to remove hurdles in ensure "effective" implementation of FDI in multi-brand retail. 

The city government will bring an amendment to theAgricultural Produce Marketing Committee (APMC) Act for facilitating direct purchase of produce from farmers by multi-national retailers. 

The amendment to the existing legislation will allow direct connectivity between retailers and farmers.

Officials said the amendment to APMC Act was required to "break monopoly" of the wholesale traders so that retailers can directly buy agricultural produce from farmers.

Google + crosses 135 million active users, adds photo sharing app

Image
Google said Thursday its online social network had grown to 135 million active users, as it added a photo-sharing app to compete against services like Facebook's Instagram. 

"Today Google+ is the fastest-growing network thingy ever," said Google senior vice president Vic Gundotra in a blog post. 

He added that "135 million (users) are active in just the stream," and that more than 500 million have upgraded their Google accounts to potentially participate in the social network, which aims to rival Facebook.  "This enthusiasm, we think, stems from our building tools that build real relationships -- in a live hangout, around a breathtaking photo, or with an inner circle offriends," Gundotra said. 

"So today we're launching two new improvements that help bring the nuance and richness of real-life sharing to software." 

Google said it has now introduced the mobile photo-sharing service Snapseed, made by Nik Software, to the social network. Googl…

Stallman Appeals Free Software Users To Ban Ubuntu!

Image
Free Software Foundation founder Richard Stallman calls Ubuntu 'spyware' and as bad as Windows.

Free Software Foundation founder Richard Stallman has now attacked Ubuntu distribution calling it a 'spyware' and as bad as Windows. Stallman said that the latest version of the Linux-based operating system, contains dangerous 'surveillance code'.

In his post on the FSF blog, Stallman has criticised Ubuntu and the company behind it for adding the search feature in the latest version of the distribution. According to him, this version of Ubuntu sends packets to Canonical's servers without the knowledge of the users.
Canonical had first introduced the 'Home Lens' unified search feature in Ubuntu 12.10. The feature inserts product recommendations from Amazon into the search result, irrespective of whether the users searched the web or local files. Stallman wrote, “This is just like the first surveillance practice I learned about in Windows. My late friend Fravi…

US election, iPhone 5 and Kim Kardashian are top Yahoo! 2012 searches

Image
The US presidential election became the most-searched item and Kim Kardashian was the most-searched person on Yahoo! in a year when online searches were dominated by big news stories and pop culture obsessions, the search engine company said on Monday. 

The search term "election" topped the list of searches, led not only by extensive media coverage but also widening conversation on online social media platforms.

The term "political polls" was No. 8 of the top 10 Yahoo! searches of the year. 

"The 2012 elections dominated the online searches, which is amazing because if something is in the news, it's already accessible ... people were really saturated by it, but even so, that was a key word that people typed throughout the year," Vera Chan, Yahoo!'s web trend analyst, said in a conference call. 

Chan said only two other news stories have topped the list in the past decade, those being the death ofMichael Jackson in 2009 and the BP oil spill in 2010.

Suggest a title for the following chunk of Elijah Shopper's story

And as he entered the cave, he found complete darkness, except a small beam coming from somewhere in front of him. It made him understand that the cave was deep enough. He touched the sidewall, found it rough, and he felt like if he had put his hand in a lot of sand. He took his hand of the wall and jolted it, and he could smell the dust. There was no sound. Being brave enough, he started moving, getting stumbled by hitting the crests in the path, but he kept moving. It was a hole in the ceiling of the cave, from where the light beams were coming. Though it was dark, he opened the map. “Pirate Tikona’s Base” he muttered, and waited for a while. Map was still blank. “Perhaps this is a waste of time”, he thought, “let me try again”, and screamed this time “Pirate Tikona’s Base”. And the next moment, his heart got filled with fear as he heard sounds like those of cloud thunder, and suddenly a number of holds appeared in the ceiling of the cave. Perhaps the cave had awakened.
