Samsung expected to sue Apple over iPhone 5 tomorrow

Posted on by

The courtroom battle between Apple and Samsung seems to be far from over, and come tomorrow Apple is in for a major headache as soon as it makes the iPhone 5 official. That’s because Samsung is poised to sue the company over patents it owns relating to the LTE connectivity the new smartphone is expected to use.

Facing Samsung in court again may not phase Apple even though the shoe will firmly be on the other foot this time. However, there’s two other companies set to try and block sales of the new iPhone. The first is the company behind the GooPhone i5, which successfully managed to patent the design of its phone in China that just happens to look like the leaked shots we have seen of the iPhone 5. If the two phones do indeed look the same, expect a lawsuit.

3 years later, hackers who hit Google continue string of potent attacks

The hackers who breached the defenses of Google and at least 34 other big companies three years ago have unleashed a barrage of new attacks since then, many that exploit previously undocumented vulnerabilities in software from Microsoft and Adobe, a new report has found.

Researchers have dubbed this approach “watering hole” attacks, and say they’re “similar to a predator waiting at a watering hole in a desert. The predator knows that victims will eventually have to come to the watering hole, so rather than go hunting, he waits for his victims to come to him.”

Using ultraviolet light to fabricate thin flexible electronics

Posted on by

A new method for making metal oxide devices at much lower temperatures uses ultraviolet (UV) irradiation. Yong-Hoon Kim and colleagues used UV light to chemically activate metal particles in a chemical solution; the new metal oxide molecules condensed out of the solution, forming a thin semiconducting film. The process can be performed at room temperature—far lower than the 350° temperatures typical of metal oxide fabrication.

The high temperatures are the problem. 350°C is above the melting point of most flexible, transparent substances (e.g. plastics), and real electronic devices need a substrate to give them shape. It doesn’t matter how thin or transparent metal oxide devices are if they must be deposited on thick, opaque, rigid materials.

GoDaddy is Down, Anonymous Claims Responsibility

Godaddy.com is down, but so are some of the site’s DNS servers, which means GoDaddy hosted e-mail accounts are down as well, and lots more. It’s currently unclear if the servers are being unresponsive or if they are completely offline. Either way, the result is that if your DNS is hosted on GoDaddy, your site may also look as if it is down, because it cannot resolve.

Describing the mission as a milestone in the nation’s space capabilities, he said the launch was “testimony to the commercial competitiveness of the Indian space industry and is a tribute to Indian innovation and ingenuity”.

A beaming ISRO chief K. Radhakrishnan told the post-launch media conference that with today’s successful mission the agency has launched 62 satellites, one space recovery module and 37 rockets, making it a grand 100.

AFS is a distributed filesystem product, pioneered at Carnegie Mellon University and supported and developed as a product by Transarc Corporation (now IBM Pittsburgh Labs). It offers a client-server architecture for federated file sharing and replicated read-only content distribution, providing location independence, scalability, security, and transparent migration capabilities. AFS is available for a broad range of heterogeneous systems including UNIX, Linux,  MacOS X, and Microsoft Windows

IBM branched the source of the AFS product, and made a copy of the source available for community development and maintenance. They called the release OpenAFS.

Penn Researchers Make First All-optical Nanowire Switch

Posted on by

Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.

The researchers were able to measure the intensity of the light coming out of the end of the second nanowire and to show that the switch could effectively represent the binary states used in logic devices.

Which SSL certificate should I buy?

Posted on by

SSL certificates that most web browsers can accept without grief are sold by a relatively small number of companies. That’s because the major web browsers are shipped with a certain set of “root certificate authorities” that they trust… and if your certificate isn’t signed by one of those authorities, or by a certificate “chained” from one of them, then you’re out of luck— the web browser will display a scary warning to the user or, in some cases, refuse to work with your site at all.

The cost of SSL certificates varies quite a bit, from as little as $20 to as much as $1,000 or more. Why such a big difference? There are three main reasons:

via WWW FAQs: Which SSL certificate should I buy?.

2. Some certificates are directly signed by a trusted root certificate, while others are “chained” from another “intermediate” certificate. This isn’t really a problem, as long as the company selling you the chained certificate really does own the root certificate. But some webmasters get confused by intermediate certificates, fail to install them correctly, and mistakenly think they have purchased a bad certificate. So chained certificates are usually less expensive to allow for this inconvenience, even though there is no real technical disadvantage.

Quantum test pricks uncertainty

Posted on by

Heisenberg’s uncertainty principle, as it came to be known later, started as an assertion that when trying to measure one aspect of a particle precisely, say its position, experimenters would necessarily “blur out” the precision in its speed.

That raised the spectre of a physical world whose nature was, beyond some fundamental level, unknowable.

via BBC News – Quantum test pricks uncertainty.

Photons can be prepared in pairs which are inextricably tied to one another, in a delicate quantum state called entanglement, and the weak measurement idea is to infer information about them as they pass, before and after carrying out a formal measurement.

What the team found was that the act of measuring did not appreciably “blur out” what could be known about the pairs.
