Submission + - Interview with Barbara Liskov

twofishy writes: Turing award winner Barbara Liskov is Professor of Engineering in the MIT School of Engineering's Electrical Engineering and Computer Science department and an Institute Professor at the Massachusetts Institute of Technology. She is best known for the Liskov Substitution Principle which is named for her (though not coined by her). She gave a keynote at QCon London, and afterwards gave an interview in which she discusses language design, modularity and distributed computation. On the Liskov Substitution Principle

"So it’s a very simple rule, it’s really very intuitive and what it means is that if you have a type that is a subtype of another type and you use an object of that subtype in a context where you expect an object of the supertype, then the object of the subtype ought to behave like you expect. In other words you’re depending upon the specification of the supertype and the object should meet that specification even though it might belong to a subtype."

Submission + - Bitcoin breaks $100 USD (

jeremy85mai writes: "Yesterday, while a number of banks were closed, bitcoin decided to break another major psychological barrier, and is now trading at above $100 USD per coin. At the moment, Bitcoin is trading at $118 USD/BTC. There is very little resistance to further price increases, so expect the price of bitcoin to rise very rapidly over the next few weeks. These are also record highs for the currency. "

Submission + - Bitcoin crosses 1 billion USD market value threshold (

jeremy85mai writes: From the article:
"Today, Bitcoin crossed an important milestone for the decentralized currency, in that the net worth of all bitcoins currently minted now exceeds 1 billion US dollars. At the moment, bitcoin is trading around $94, which makes the current net market value 1.03 billion USD. This is a significant milestone, since many consider this to be the point at which bitcoin should be taken as a serious currency."


Submission + - Open DNS Resolvers Center Stage in Massive DDoS Attacks (

msm1267 writes: While the big traffic numbers and the spat between Spamhaus and illicit webhost Cyberbunker are grabbing big headlines, the underlying and percolating issue at play here has to do with the open DNS resolvers being used to DDoS the spam-fighters from Switzerland. Open resolvers do not authenticate a packet-sender’s IP address before a DNS reply is sent back. Therefore, an attacker that is able to spoof a victim’s IP address can have a DNS request bombard the victim with a 100-to-1 ratio of traffic coming back to them versus what was requested. DNS amplification attacks such as these have been used lately by hacktivists, extortionists and blacklisted webhosts to great success.

Submission + - LG Nexus 4 Leaked/Unveiled (

An anonymous reader writes: From the article:

"Earlier today, several sources revealed the specs and leaked images of the next Google Nexus device. This device will most likely be the launch vehicle for the next iteration of the Android Operating System. which will likely be a small incremental upgrade over a larger one. The device has a 4.75 inch screen, but it also has a smaller top bezel than the Galaxy Nexus does. It'll contain a quad core Qualcomm processor, and 2 GB of ram to supplement that. It does have a different rear design, which takes from the Nexus 7's back. You can click on the image of the device above to see more of it's design."


Submission + - Wall Street Journal describes how Facebooks Outs your Most Personal Secrets (

McGruber writes: The Wall Street Journal (FREE Link: is reporting that Facebook revealed the sexual preferences of users despite those users have choosen "privacy lockdown" settings on Facebook.

The article describes two students who were casualties of a privacy loophole on Facebook—the fact that anyone can be added to a group by a friend without their approval. As a result, the two lost control over their secrets, even though both students were sophisticated users who had attempted to use Facebook's privacy settings to shield some of their activities from their parents.

Facebook spokesprick Andrew Noyes responded with a statement blaming the users: "Our hearts go out to these young people. Their unfortunate experience reminds us that we must continue our work to empower and educate users about our robust privacy controls."

Submission + - Craigslist drops exclusive license to your posts (

Penurious Penguin writes: Last week on Slashdot we read the bad news, i.e. "Craigslist Demands Exclusivity For Postings", an odd demand which would have prevented ad-content on Craigslist from being advertised anywhere else but Craigslist. Thankfully, today we read from the EFF, the Good News: Craigslist drops exclusive license to your posts.

Perhaps they can now apply their ambitions toward improving Craigslist in other ways?


Submission + - Custom Android ROM Developers get OTA Update Capabilties like Carriers ( 1

hypnosec writes: A new service dubbed OTA Update Center has been launched that enables Android ROM developers to provide over-the-air (OTA) updates of their ROMs in a centralized and easy fashion. Custom ROM developers had very little at their disposal when it came to providing updates and when any user with such a ROM did want to apply an update, he/she was required to reinstall the new ROM from scratch that often involved deletion of backup, installation of new ROM, restoration of data. This was a lengthy process and often a deterrent when it came to updating the ROM. Also, the developers were required to have their own infrastructure whereby they would be required to host their own servers and have the required bandwidth to serve scores of downloads. The OTA Update Center changes this and provides a free to use service that is easy and noon-friendly to use. The website reads, “This project is especially for the rom devs around, to be able to implement an easy to use, and free OTA Update app.”

Submission + - IPv6: What Are They Really Thinking? (

sarfralogy writes: "IPv6 is here. Well, it has been for 16 years now, but aptly enough, World IPv6 Day is all about its coming of age. No candles or shoe ceremonies at this event, simply a lot of big names with seemingly altruistic and forward-looking intent. Want to see if your setup can handle it? Probably not, unless you just bought a cutting-edge router, and connect to an ISP with widespread IPv6 deployment (there aren't any, BTW, but Comcast, Time Warner, Sprint, and AT&T are trying. No word from Cox, Cablevision, Verizon, or T-Mobile).
Still, IPv6 is an inevitable reality, although it will coexist for the time being with IPv4. As more and more IPv6 sites and hardware become the norm, IPv4 will become increasingly isolated and detrimental to stubborn businesses. Many companies are convinced that the time is now, and are helping The Internet Society push for IPv6 deployment and awareness.
Okay, but why? Well, the biggest reason is simply that we're running out of IPv4 addresses. That alone is worth transitioning to a more capacious specification. Get used to the word "undecillion," as in "IPv6 allows for 340 undecillion addresses, instead of a measly 4 billion or so with IPv4." The fundamental benefit is that all of those devices that are currently behind a NAT router will now be able to connect directly. This frees up all of the resources wasted in directing local network traffic through the bottleneck of a shared IP address."


Submission + - Court Rules NSA Doesn't Have To Confirm Or Deny Secret Relationship With Google ( 1

Sparrowvsrevolution writes: A DC appeals court has ruled that the National Security Agency doesn’t need to either confirm or deny its secret relationship with Google in response to a Freedom of Information Act (FOIA) request and follow-up lawsuit filed by the Electronic Privacy Information Center. The NSA cited a FOIA exemption that covers any documents whose exposure might hinder the NSA’s national security mission, and responded to EPIC with a "no comment." Beyond merely rejecting the FOIA request, the court has agreed with the NSA that it has the right to simply not respond to the request, as even a rejection of the request might reveal details of a suspected relationship with Google that it has sought to keep secret.

Google was reported to have partnered with the NSA to bolster its defenses against hackers after its breach by Chinese cyberspies in early 2010. But to the dismay of privacy advocates who fear the NSA's surveillance measures coupled with Google's trove of data, the company has never explained the details of that partnership.
