Submission + - Intel To Start Shipping a Quantum Processor (arstechnica.com)

Submitted by Anonymous Coward
An anonymous reader writes: Intel does a lot of things, but it's mostly noted for making and shipping a lot of processors, many of which have been named after bodies of water. So, saying that the company is set to start sending out a processor called Tunnel Falls would seem unsurprising if it weren't for some key details. Among them: The processor's functional units are qubits, and you shouldn't expect to be able to pick one up on New Egg. Ever. Tunnel Falls appears to be named after a waterfall near Intel's Oregon facility, where the company's quantum research team does much of its work. It's a 12-qubit chip, which places it well behind the qubit count of many of Intel's competitors—all of which are making processors available via cloud services. But Jim Clarke, who heads Intel's quantum efforts, said these differences were due to the company's distinct approach to developing quantum computers.

Intel, in contrast, is attempting to build silicon-based qubits that can benefit from the developments that most of the rest of the company is working on. The company hopes to "ride the coattails of what the CMOS industry has been doing for years," Clarke said in a call with the press and analysts. The goal, according to Clarke, is to make sure the answer to "what do we have to change from our silicon chip in order to make it?" is "as little as possible." The qubits are based on quantum dots, structures that are smaller than the wavelength of an electron in the material. Quantum dots can be used to trap individual electrons, and the properties of the electron can then be addressed to store quantum information. Intel uses its fabrication expertise to craft the quantum dot and create all the neighboring features needed to set and read its state and perform manipulations.

However, Clarke said there are different ways of encoding a qubit in a quantum dot (Loss-DiVincenzo, singlet-triplet, and exchange-only, for those curious). This gets at another key difference with Intel's efforts: While most of its competitors are focused solely on fostering a software developer community, Intel is simultaneously trying to develop a community that will help it improve its hardware. (For software developers, the company also released a software developer kit.) To help get this community going, Intel will send Tunnel Falls processors out to a few universities: The Universities of Maryland, Rochester, Wisconsin, and Sandia National Lab will be the first to receive the new chip, and the company is interested in signing up others. The hope is that researchers at these sites will help Intel characterize sources of error and which forms of qubits provide the best performance.

Submission + - Hackers Can Steal Cryptographic Keys By Video-Recording Power LEDs 60 Feet Away (arstechnica.com)

Submitted by Anonymous Coward
An anonymous reader writes: Researchers have devised a novel attack that recovers the secret encryption keys stored in smart cards and smartphones by using cameras in iPhones or commercial surveillance systems to video record power LEDs that show when the card reader or smartphone is turned on. The attacks enable a new way to exploit two previously disclosed side channels, a class of attack that measures physical effects that leak from a device as it performs a cryptographic operation. By carefully monitoring characteristics such as power consumption, sound, electromagnetic emissions, or the amount of time it takes for an operation to occur, attackers can assemble enough information to recover secret keys that underpin the security and confidentiality of a cryptographic algorithm. [...]

On Tuesday, academic researchers unveiled new research demonstrating attacks that provide a novel way to exploit these types of side channels. The first attack uses an Internet-connected surveillance camera to take a high-speed video of the power LED on a smart card reader—or of an attached peripheral device—during cryptographic operations. This technique allowed the researchers to pull a 256-bit ECDSA key off the same government-approved smart card used in Minerva. The other allowed the researchers to recover the private SIKE key of a Samsung Galaxy S8 phone by training the camera of an iPhone 13 on the power LED of a USB speaker connected to the handset, in a similar way to how Hertzbleed pulled SIKE keys off Intel and AMD CPUs. Power LEDs are designed to indicate when a device is turned on. They typically cast a blue or violet light that varies in brightness and color depending on the power consumption of the device they are connected to.

There are limitations to both attacks that make them unfeasible in many (but not all) real-world scenarios (more on that later). Despite this, the published research is groundbreaking because it provides an entirely new way to facilitate side-channel attacks. Not only that, but the new method removes the biggest barrier holding back previously existing methods from exploiting side channels: the need to have instruments such as an oscilloscope, electric probes, or other objects touching or being in proximity to the device being attacked. In Minerva's case, the device hosting the smart card reader had to be compromised for researchers to collect precise-enough measurements. Hertzbleed, by contrast, didn’t rely on a compromised device but instead took 18 days of constant interaction with the vulnerable device to recover the private SIKE key. To attack many other side channels, such as the one in the World War II encrypted teletype terminal, attackers must have specialized and often expensive instruments attached or near the targeted device. The video-based attacks presented on Tuesday reduce or completely eliminate such requirements. All that’s required to steal the private key stored on the smart card is an Internet-connected surveillance camera that can be as far as 62 feet away from the targeted reader. The side-channel attack on the Samsung Galaxy handset can be performed by an iPhone 13 camera that’s already present in the same room.

Ironic really. At it's inception, microsoft got in on the paradigm transition from mainframe to desktop computing, albeit not through any real innovation or offering of value. IBM and mainframes are still around and arguably profitable, but not relevant in terms of what drives current trends of innovation - at that point new and interesting directions started coming from the desktop computing world. Think of every thing you do on a desktop computer now, and it's likely something that didn't arise from the IBM/Mainframe computing world. Now things like google glass, new distribution models like hadoop, hyperscale computing, and "cloud" computing (yes I held my nose when typing the "C" word) are arising in a sense from the budding influence of the mobile computing world.

So now the paradigm is shifting to mobile, and MS has missed the boat in almost every definable way. But like IBM, they'll stay around and still be profitable, but they just won't be relevant in terms of new directions in the information landscape. The apple didn't fall far from the tree, no pun intended.

Mint has actually done a pretty good job of making Gnome3 work very much like Gnome2. You can run it with a UI called Cinnamon, that's even more like Gnome2.

However, Mint puts their own google search in the browser so when you use the browser's search field, it uses Mint's google search. Still, that beats adware built into the desktop.

If neither Mint nor Amazon/Unity/Ubuntu works and Gnome 3 sucks, try Lubuntu.

Turns out the patent has nothing to do with "things X-Plane has done for decades".

Kind of and kind of not. The patent the troll is claiming has been infringed on is for things others have done for decades - remote license checking:

Section 107 of the patent, which they claim I violated, contains: “107. code for verifying the license data stored on the licensing medium by communicating with a registration authority having verification data.”

The article goes on to point out a few others that have been doing this for decades. HP Openview has been doing it for as long as it has existed. I'm sure scores of others not listed have as well. Honestly, it's been a common practice for decades to be certain.

This is just another example of how software patenting is bad for the industry. Trolls can get patents on nearly anything, then file a lawsuit that while doomed by prior art will cost the victim a lot to show that prior art. Which the Patent office should have found before granting the patent in the first place.

Submission + - NEOShield to assess Earth Defence (bbc.co.uk)

Submitted by arisvega
arisvega writes: NEOShield is a new international project that will assess the threat posed by Near Earth Objects (NEO) and look at the best possible solutions for dealing with a big asteroid or comet on a collision path with our planet.

The effort is being led from the German space agency's (DLR) Institute of Planetary Research in Berlin, and had its kick-off meeting this week.

It will draw on expertise from across Europe, Russia and the US.

It's a major EU-funded initiative that will pull together all the latest science, initiate a fair few laboratory experiments and new modelling work, and then try to come to some definitive positions.

Industrial partners, which include the German, British and French divisions of the big Astrium space company, will consider the engineering architecture required to deflect one of these bodies out of our path.

Submission + - How the US Lost Out on iPhone Work

Hugh Pickens writes
Hugh Pickens writes writes: "Not long ago, Apple boasted that its products were made in America. Today, almost all of the 70 million iPhones, 30 million iPads and 59 million other products Apple sold last year manufactured overseas. "It isn’t just that workers are cheaper abroad," write Charles Duhig and Keith Bradsher. "Rather, Apple’s executives believe the vast scale of overseas factories as well as the flexibility, diligence and industrial skills of foreign workers have outpaced their American counterparts so much that “Made in the U.S.A.” is no longer a viable option for most Apple products." Apple executives say that going overseas, at this point, is their only option and recount the time Apple redesigned the iPhone’s screen at the last minute, forcing an assembly line overhaul. A foreman immediately roused 8,000 workers inside the company’s dormitories, each employee was given a biscuit and a cup of tea, guided to a workstation and within half an hour started a 12-hour shift fitting glass screens into beveled frames. Within 96 hours, the plant was producing over 10,000 iPhones a day. “The speed and flexibility is breathtaking,” says one Apple executive. “There’s no American plant that can match that.” Apple’s success has benefited the US economy by empowering entrepreneurs and creating jobs at companies like cellular providers and businesses shipping Apple products but ultimately, Apple executives say curing unemployment is not Apple's job. “We don’t have an obligation to solve America’s problems. Our only obligation is making the best product possible.”"

Interestingly, if not ironic, the Preview application lets you annotate PDFs freely, regardless of any 'digital publishing' rights limitations like the adobe reader does. That's the chief reason I use OSX. Its the easiest and best PDF reader/annotator available, and I have a lot of books in PDF format, and I'm still converting the .chm and other ebooks to PDF for just that reason.

If you're using Apple products, that means that you're looking at the world through a very bent straw, and Apple is doing the bending.

No not really. I'm not comfortable with the show "appstore" thing, and if it get's to be draconian I'll dump OSX, but that statement isn't true, unless you really want it to be.
