+ - Interview with Barbara Liskov

Submitted by twofishy
twofishy (1658233) 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."

+ - Google is actively developing products against users of alternative browsers->

Submitted by epSos-de
epSos-de (2741969) writes "Google said: "Don't be evil". In reality they are actively discriminating against browsers that are not based on Google Chrome. Opera is repeatedly crippled in gMail. Google's Java Scripts are prohibiting Opera users from selecting and copying text in the Opera browser.

Opera did resolve the issue with every new release, but Google still keeps changing their code, so that users of Opera are not allowed to select and copy text, when they are using gMail. The first few times, it was suspicious, but now it is too obvious that Google is actively developing products that can not be used outside of the Google Chrome."

jeremy85mai (2520912) 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. ""

Submitted by theodp
theodp (442580) writes "If you're a bright kid who wants to prepare for the 21st century workforce (pdf) by studying engineering at Purdue, the government will help your parents pay the $100,000 or so tuition tab with a 7.9% interest loan (plus 4% fees) that's likely to be non-dischargeable in bankruptcy and paid back with after-tax money. If, on the other hand, you want to buy a tricked-out $100,000 Model S, Tesla has teamed up with the government, Wells Fargo, and U.S. Bank on what it calls a 'Revolutionary New Finance Product' that enables those who play the game right to avoid paying sales tax, get the government to pick up the first $15,000 (no down payment needed!), and also receive a 2.95% bankruptcy-dischargeable loan for the balance, the payments for which could be tax-deductible. Yep, 'Revolutionary' may be about right!"

+ - Did the Spamhaus DDos really slow down global Internet access?->

Submitted by
CowboyRobot
CowboyRobot writes "Despite the headlines, the big denial of service attack may not have slowed the Internet after all. The argument against the original claim include the fact that reports of Internet users seeing slowdowns came not from service providers, but the DDoS mitigation service CloudFlare, which signed up Spamhaus as a customer last week. Also, multiple service providers and Internet watchers have now publicly stated that while the DDoS attacks against Spamhaus could theoretically have led to slowdowns, they've seen no evidence that this occurred for general Internet users. And while some users may have noticed a slowdown, the undersea cable cuts discovered by Egyptian sailors had more of an impact than the DDoS."

Submitted by jeremy85mai
jeremy85mai (2520912) 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.""

+ - Open DNS Resolvers Center Stage in Massive DDoS Attacks ->

Submitted by msm1267
msm1267 (2804139) 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."

In it's pledge Google says that they will not sue any user, distributor or developer of open-source software on specified patents, unless first attacked. Under this pledge, Google is starting off with 10 patents relating to MapReduce, a computing model for processing large data sets first developed at Google. Google says that over time they intend to expand the set of Google’s patents covered by the pledge to other technologies."

Submitted by Anonymous Coward
An anonymous reader writes "As many of you know, part of my popularity analysis of GNU/Linux distributions includes search engine results. One thing I immediately noticed when I started analyzing the data was how fewer results Bing has compared to Google specifically for the term "Ubuntu Linux". At first, I thought that perhaps Bing simply hasn't indexed as much as Google and it will catch up. But over several ranking periods now, Bing is still, in my opinion, unusually low in "Ubuntu Linux" results. So I did a quick and dirty experiment:"

Submitted by
netbuzz
netbuzz writes "A federal judge in Texas, presiding over a district notorious for favoring patent trolls, has summarily dismissed all claims relating to a case brought by Uniloc USA against Rackspace for allegedly infringing upon Linux patents. Red Hat defended Rackspace in the matter and issued a press release saying: “In dismissing the case, Chief Judge Leonard Davis found that Uniloc’s claim was unpatentable under Supreme Court case law that prohibits the patenting of mathematical algorithms. This is the first reported instance in which the Eastern District of Texas has granted an early motion to dismiss finding a patent invalid because it claimed unpatentable subject matter.”"
