Google: Computer Science for High School (CS4HS) DNA testing service will test your girlfriend's underwear to find out if she's cheating. DNA testing company the Paternity Lab Center has come up with an ingenious (re: horrifying) way to identify unfaithful partners: for a mere $200, the good folks at Infidelity DNA Testing will test a pair of your partner's panties for telltale traces of semen.
Although most of the company's clients are men, women can also test their husbands or boyfriends' underwear for traces of vaginal fluids. According to the company's website, there are two forms of infidelity DNA testing: semen testing using a prostate specific antigen (PSA) test, and testing for female DNA. For the PSA test, the process works by testing whether semen is present in the sample, ensuring its viability for DNA extraction, and doing a final comparison to confirm the DNA belongs to the right person.

El calendario actual podemos decir que es un desastre por lo engorroso que resulta que algunos meses tengan más días que otros, que cada cuatro años haya un día extra o que si un año una fecha cae en cierto día, al año siguiente caerá en otro día distinto.
Increíble video: ¿Levitación cuántica? Un paso más cerca de la patineta de Marty. Microsoft Is Working On A Holodeck. About Damn Time! By Jill Pantozzi | 2:50 pm, January 2nd, 2012 Microsoft has been working on something very interesting in their Edison lab in Redmond, Washington.
They’re likening it to a holodeck. The chance of a lifetime. A friend asked me the other day, "...given the sorry state of so much in the world, what's possible to look forward to? " The state isn't sorry. It's wide open. Interest rates are super low, violence is close to an all time low, industries are being remade and there's more leverage for the insurgent outsider than ever before in history.
The status quo is taking a beating, there's no question about it. Post-quantum cryptography. Post-quantum cryptography refers to research on cryptographic primitives (usually public-key cryptosystems) that are not efficiently breakable using quantum computers more than classical computer architectures.
This term came about because most currently popular public-key cryptosystems rely on the integer factorization problem or discrete logarithm problem, both of which would be easily solvable on large enough quantum computers using Shor's algorithm. Even though current publicly known experimental quantum computing is nowhere near powerful enough to attack real cryptosystems, many cryptographers are researching new algorithms in case quantum computing becomes a threat in the future. This work has been popularized by the PQCrypto conference series since 2006. Shor's algorithm. Shor's algorithm, named after mathematician Peter Shor, is a quantum algorithm (an algorithm that runs on a quantum computer) for integer factorization formulated in 1994.
Informally it solves the following problem: Given an integer N, find its prime factors. On a quantum computer, to factor an integer N, Shor's algorithm runs in polynomial time (the time taken is polynomial in log N, which is the size of the input). Specifically it takes time O((log N)3), demonstrating that the integer factorization problem can be efficiently solved on a quantum computer and is thus in the complexity class BQP. This is substantially faster than the most efficient known classical factoring algorithm, the general number field sieve, which works in sub-exponential time — about O(e1.9 (log N)1/3 (log log N)2/3). The efficiency of Shor's algorithm is due to the efficiency of the quantum Fourier transform, and modular exponentiation by repeated squarings.
Procedure , find an integer and . The Fabric of Reality. The Fabric of Reality is a book by physicist David Deutsch written in 1997.
It expands upon his views of quantum mechanics and its implications for understanding reality. This interpretation, which he calls the multiverse hypothesis, is one of a four-strand Theory of Everything (TOE). The four strands are: Zuse's Thesis - Zuse hypothesis - Algorithmic Theory of Everything - Digital Physics, Rechnender Raum (Computing Space, Computing Cosmos) - Computable Universe - The Universe is a Computer - Theory of Everything. Konrad Zuse (1910-1995; pronounce: "Conrud Tsoosay") not only built the first programmable computers (1935-1941) and devised the first higher-level programming language (1945), but also was the first to suggest (in 1967) that the entire universe is being computed on a computer, possibly a cellular automaton (CA).
Digital physics. Digital physics is grounded in one or more of the following hypotheses; listed in order of decreasing strength. The universe, or reality: History The hypothesis that the universe is a digital computer was pioneered by Konrad Zuse in his book Rechnender Raum (translated into English as Calculating Space). The term digital physics was first employed by Edward Fredkin, who later came to prefer the term digital philosophy. Others who have modeled the universe as a giant computer include Stephen Wolfram, Juergen Schmidhuber, and Nobel laureate Gerard 't Hooft. These authors hold that the apparently probabilistic nature of quantum physics is not necessarily incompatible with the notion of computability.
Calculating Space. Calculating Space is the title of MIT's English translation of Konrad Zuse's 1969 book Rechnender Raum (literally: "space that is computing"), the first book on digital physics. Zuse proposed that the universe is being computed by some sort of cellular automaton or other discrete computing machinery, challenging the long-held view that some physical laws are continuous by nature. He focused on cellular automata as a possible substrate of the computation, and pointed out (among other things) that the classical notions of entropy and its growth do not make sense in deterministically computed universes. Bell's theorem is sometimes thought to contradict Zuse's hypothesis, but it is not applicable to deterministic universes, as Bell himself pointed out.

Much of his early work was financed by his family and commerce, but after 1939 he was given resources by the Nazi German government. Due to World War II, Zuse's work went largely unnoticed in the United Kingdom and the United States. Possibly his first documented influence on a US company was IBM's option on his patents in 1946. Pre-World War II work and the Z1 Born in Berlin, Germany, on 22 June 1910, he moved with his family in 1912 to Braunsberg, East Prussia, where his father was a postal clerk. Zuse attended the Collegium Hosianum in Braunsberg. In 1923, the family moved to Hoyerswerda, where he passed his Abitur in 1928, qualifying him to enter university. He enrolled in the Technische Hochschule Berlin-Charlottenburg and explored both engineering and architecture, but found them boring.
Between 1987 and 1989, Zuse recreated the Z1, suffering a heart attack midway through the project. Bell's theorem. Bell's theorem is a no-go theorem famous for drawing an important distinction between quantum mechanics (QM) and the world as described by classical mechanics. In its simplest form, Bell's theorem states: No physical theory of local hidden variables can ever reproduce all of the predictions of quantum mechanics. In the early 1930s, the philosophical implications of the current interpretations of quantum theory were troubling to many prominent physicists of the day, including Albert Einstein.
The Bell That Rings Inside Your Mind, Is Challenging The Doors Of Time, It’s A Kind Of Magic (A Kind Of Magic - Queen) During class design we should take decisions about the assignment of responsibilities that will have every class. If we have chosen well, systems tend to be easier to understand, maintain and extend. Almost all of our projects have a persistence layer, either relational database, document stores, or simply XML files. And typically you will use DAO pattern to implement abstract interface between your business objects and your data store. In this post but I am going to explain another pattern that can be used instead of DAO pattern.
Active record pattern is an architectural pattern that force you to implement CRUD operations on your model class, hence model class itself is responsible for saving, deleting, loading from database. There are many strategies to follow to implement this pattern, but for me, the best one is using Aspect Oriented Programming, because we are still maintaining separation of concerns favoring isolated unit testing, and not breaking encapsulation.
