Microsoft has announced an upcoming Windows XP Service Pack 3. There is a test version available. The Windows XP SP3 is primarily a package of previously released updates, security updates and hotfixes. However, a test run by Devil Mountain Software, says it boosts performance. Photo can be copied from DVD The latest from Microsoft is a news of an upcoming download for Windows XP called Windows XP Service Pack 3. According to the white paper published by Microsoft to wit “This white paper is for informational purposes only. Microsoft makes no Warranties, Expressed or Implied, in this document.” The non-binding description of Windows XP Service Pack 3 (Windows XP SP3) includes all previously released Windows XP updates and hotfixes and select out-of-band releases. What’s Not in The Windows XP SP3?According to Microsoft’s white paper, the pending download does not include;Windows Internet Explorer 7, but it does include updates to both Internet Explorer 6 and 7. Windows XP SP3 will update whichever Internet Explorer you have on your system. What Does Windows XP SP3 Purport To Do?Basically what Windows XP SP3 will do for you, is to allow you to catch up on any updates, security updates and fixes you may have missed or too busy to download. Microsoft states unequivocally that the service pack does not “significantly change customer´s experience with the operating system.”For organizations and individuals, Window XP SP3 does include Network Access Protection, (NAP). This will allow users access to features in the Windows Server 2008 operating system. In addition, the white paper indicates there will be “select” out-of-band releases and a small number of new releases. Early Reports of Tests of Windows XP SP3:According to TechSpot, a test run of the service pack by Devil Mountain Software Group provided an unexpected boost in performance. The Group used a test machine made by Dell XPS M1710 with 2 GHz Core Duo CPU and 1GB of RAM and running nVidia GeForce Go 7900GS video. According to Craig Barth, Devil Mountain Software Chief Technology Officer, the test involved testing with OfficeBench. The results were a 10 percent performance boost in trials run with the Windows XP SP3 versus the previous version XP SP2. The same tests were run on Vista and according to Barth, “it is two times slower than than the most current builds of its older sibling.” While preliminary, this is good news for XP users.In conclusion, the final version of Windows XP SP3 will potentially be available in the near future. In the meantime, it will be interesting to read updated reports on the trial version currently available. There is little doubt that Microsoft would like to persuade users that Vista is the way to go, but for the time being a packaged fix at no cost to users seems fine.

© 2010 PhysOrg.com (PhysOrg.com) — By building a robotic ground-effect vehicle that flies inches above the ground, researchers from Japan may be offering a glimpse into the future of high-speed rail. The researchers, led by Yusuke Sugahara at Tohoku University, are currently testing the robotic prototype, which they have described earlier this week at the IEEE International Conference on Robotics and Automation (ICRA) in Shanghai. DARPA announces plans for self-piloted flying car More information: via: IEEE Spectrum As a ground-effect vehicle, the prototype uses the fast-moving air between the bottom of the vehicle and its track to fly above the ground. Usually, this air produces drag on planes as they’re landing, as well as on maglev trains, which levitate using electromagnets. But by taking advantage of this fast-moving air, the ground-effect vehicle can avoid the friction associated with rail contact, as well as avoid ground-effect drag.With its stubby wings, the ground-effect vehicle is controlled more like a plane than a train, since factors such as pitch, roll, and yaw need to be accounted for. The researchers are testing the prototype to better understand autonomous stabilization in a ground-effect vehicle.If the unmanned prototype works well, the researchers will develop a dynamic model of how ground-effect vehicles operate, and then use it to design and build a manned experimental prototype. Such a vehicle could travel at speeds of up to 200 kph (125 mph) around a U-shaped concrete channel.In the future, the researchers envision building a large commuter rail system that they call the Aero Train. Ideally, such a system would be less expensive and more efficient than today’s maglev trains.

Citation: Hacker tricks Apple app pay system, posts YouTube how-to (2012, July 14) retrieved 18 August 2019 from https://phys.org/news/2012-07-hacker-apple-app-youtube-how-to.html The most interesting, and troubling to some developers, feature of the new exploit was that it was so easy; no jailbreak was needed. Software developer Alexey V. Borodin aka ZonD80 showed a simple three-step technique for beating Apple’s payment systems by installing a few certificates (CA and appstore.com) and changing the DNS in Wi-Fi settings—basically a matter of installing system certificates and doing a certain Wi-Fi tweak.The technique included a fake in-app purchase server as well as a custom DNS server. The exploit worked on devices running iOS 3.0 to 6. According to reports, however, the hack did not work in specific regions around the world. The reason suggested is that developers there were using enhanced ways to protect their apps. The exploit for circumventing Apple’s in-app purchasing system was first flagged by a Russian blog i-ekb.ru. Reacting to their tips, news of the exploit tutorial was soon after reported on the Apple-watching site, 9to5 Mac. The comments were that, since the published instructions were already getting attention, the site decided to carry the story too “as a warning to the Apple developer community.” By 3 pm yesterday, the hack was getting so popular that the server enabling it bucked under the high demand. Apple, meanwhile, issued a statement. “The security of the App Store is incredibly important to us and the developer community,” Apple representative Natalie Harrison, said. “We take reports of fraudulent activity very seriously and we are investigating.”Since Apple’s App Store is such a popular storefront for buying mobile apps, the store has also been the most desirable platform for developers trying to make money. The news of such an easy and successful exploit has not gone down well with some developers who would prefer better news, such as how Apple’s purchase system is adequately secure.Developer Marco Tabini told Macworld that Apple’s approach to receipt validation is flawed.“The whole point of the [in-app purchase] system and the App Store is that you shouldn’t have to worry about the system,” Tabini said. “Otherwise, what are you giving Apple its 30 percent for?” (Phys.org) — Apple’s 2012 Friday the Thirteenth turned memorable for the company yesterday with news outside Apple traveling fast and furious that a hacker was offering instructions on a YouTube video, telling iOS users how to wrest free access to paid iOS app content. The exploit was first posted earlier in the week, but achieved wide attention early Friday, with postings on numerous websites. A Russian hacker found a way to get hold of in-app purchasing power. Using the name ZonD80, he was also, it was learned, running a website In-AppStore.com with everything needed for the hack to work. He said donations were being accepted to support the project and help to keep servers up and running.

Southwest forest trees will grow much slower in the 21st century As the planet continues to warm, scientists study the resulting environmental impacts. In this new effort, the researchers found that regenerating young fir trees in several western states were unable to grow to fruition due to warmer and drier conditions over the past several decades.To learn more about the possible impact of global warming on forest regeneration, the researchers studied tree rings from approximately 3,000 young trees in parts of Colorado, California and the Northern Rockies. They compared the results with climate data for the same area over the past 30 years, finding what they describe as thresholds for young Douglas fir and ponderosa pine trees—if weather conditions go over the threshold, the young trees die. For the ponderosa pine, the threshold involved humidity levels. For Douglas fir, it was soil moisture levels. The researchers report that they found that almost all of the areas they studied exceeded environmental threshold levels at least once over the past 20 years. They note that as young trees find it more difficult to grow to maturity after fires, the end result could very well be land that never re-forests—instead, it would be taken over by other types of vegetation.The researchers also point out that their findings are rather ominous in light of the fact that forest fires in the western U.S. are happening more often and have become larger—also likely due to global warming. In 2018, for example, wildfires consumed 8.7 million acres of forest, which was 32 percent higher than the average amount of loss each year over the past decade. More information: Kimberley T. Davis et al. Wildfires and climate change push low-elevation forests across a critical climate threshold for tree regeneration, Proceedings of the National Academy of Sciences (2019). DOI: 10.1073/pnas.1815107116 A team of researchers from the University of Montana, the University of Colorado and the U.S. Forest Service has found evidence that suggests low-elevation forests have difficult recoveries after forest fires due to climate change. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of Douglas fir and ponderosa pine trees in several parts of the western U.S. after fires and what they observed.

Explore further The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular momentum of the electronic spins and the rotation of the rod. The NMR technique employed by Arabgol and Sleator, called CPMG-Add, works by processing a series of very weak signals (or echoes). The resulting signal was strong enough to be easily detected by the researchers’ setup, to the point that the achieved rotational speeds changed it by a significant amount. “As far as I can say, the beauty of this experiment was not finding an extraordinary technique or utilizing a novel apparatus, but finding the very narrow combination of many parameters in the experiment and running the whole experiment with the highest level of care and awareness about the variety of available noises,” Arabgol said. “Our most interesting observation was that it is, in fact, possible to magnetize protons just by rotating a sample. That was quite exciting, since the electronic counterpart of this effect had been observed almost 100 years ago and we were not sure if it was possible to do the same thing for protons, especially seeing as the same effect is nearly 700 times smaller in protons compared to electrons.”Arabgol and Sleator were the first to magnetize protons, attaining a reliable observation of the nuclear Barnett effect. Another interesting aspect of their study is that the magnetization they observed has nothing to do with magnetic fields. This is particularly noteworthy, as researchers have so far typically magnetized objects by applying a magnetic field to them. The study carried out by Arabgol and Sleator, however, proves that there are, in fact, other mechanisms that can induce magnetization without necessarily creating a magnetic field. From a theoretical standpoint, these observations enhance the current understanding of the relationship between magnetization and rotation. From a practical standpoint, they could aid the development of ultra-low-frequency NMR systems by introducing a new technique for inducing magnetization that does not require magnets.”We conducted our experiment for liquids,” Arabgol said. “A very logical next step would be to validate the results for solids. Measuring the Barnett effect for solids would be much harder using the same technique. As we explained before, the effect is so small that only a very narrow combination of parameters eventually worked, and unfortunately, it is nearly impossible to find such a combination for solids. It is noteworthy, however, that ours is merely one approach to tackle this problem. Other techniques (e.g. SQUID-based methods) might be more promising.” © 2019 Science X Network Figure representing the main idea behind the experiment. Credit: Mohsen Arabgol.

Using a different method from that employed by Barnett, two researchers at NYU observed an alternative version of this effect called the nuclear Barnett effect, which results from the magnetization of protons rather than electrons. Their study, published in Physical Review Letters (PRL), led to the first experimental observation of this effect. “I was a graduate student at NYU where a group of colleagues were involved in a project related to brain imaging,” Mohsen Arabgol, one of the researchers who carried out the study, told Phys.org. The fundamental idea behind the project was polarizing the brain molecules by inducing rotation using the Barnett effect and then applying the MRI-type imaging. I became interested and decided to work on the detection of the nuclear Barnett effect as my Ph.D. dissertation.”Initially, Arabgol and his supervisor Tycho Sleator wanted to drive rotation of the body used in their experiments by transferring the orbital angular momentum of light into the sample. They soon realized that this technique didn’t really work, and thus decided to employ a more promising method using a mechanical spinner to drive rotation.”The mechanical spinner allowed us to spin a larger sample of water up to speeds close to 15,000 revolutions per second, and finally, we were able to demonstrate the nuclear Barnett effect,” Arabgol said. In their experiments, Arabgol and Sleator used a commercial spinner turbine to rotate a sample of water up to very high speeds. They also used a non-standard nuclear magnetic resonance (NMR) machine that is designed to operate at low frequencies. This is in stark contrast with commercial NMR systems, which operate in high frequency. “In our experiment, we were looking for a change in the NMR signal that was inversely proportional to the NMR frequency,” Arabgol said. “So ironically, we wanted a low-frequency NMR apparatus, and we had to design and assemble the parts ourselves. To put this into numbers, we ended up working with an apparatus that was operating in less than 1 MHz, and we started searching for a few (1 to 3) percent change in the signal. If we wanted to use a standard apparatus, we had to search for a change in the signal few orders of magnitude smaller, which is impossible due to the variety of noises.” Journal information: Physical Review Letters
But it’s not entirely true. Last year at the World Economic Forum in Davos, I wanted to understand the impact of power on people. I sat down with two dozen leaders, including the current or former CEOs of Microsoft, Google, General Motors, Goldman Sachs and the Gates Foundation. Over and over again, I heard that power doesn’t change people as much as it accentuates their preexisting traits. Read the whole story: The Washington Post Another day, another leader seems to fall from a seat of power. The #MeToo movement has shown us devastating evidence of how male superiors have abused their power over female subordinates. The Catholic Church has offered demoralizing revelations of how priests have abused their power over nuns and children. When leaders cross the line, we often blame power. As Lord Acton famously expressed it, “power tends to corrupt and absolute power corrupts absolutely.”
In just a handful of years, the business of emotion detection — using artificial intelligence to identify how people are feeling — has moved beyond the stuff of science fiction to a $20 billion industry. Companies like IBM and Microsoft tout software that can analyze facial expressions and match them to certain emotions, a would-be superpower that companies could use to tell how customers respond to a new product or how a job candidate is feeling during an interview. But a far-reaching review of emotion research finds that the science underlying these technologies is deeply flawed. The problem? You can’t reliably judge how someone feels from what their face is doing. A group of scientists brought together by the Association for Psychological Science spent two years exploring this idea. After reviewing more than 1,000 studies, the five researchers concluded that the relationship between facial expression and emotion is nebulous, convoluted and far from universal. “About 20 to 30 percent of the time, people make the expected facial expression,” such as smiling when happy, said Lisa Feldman Barrett, a professor of psychology at Northeastern University, who worked on the report published earlier this month. But the rest of the time, they don’t. “They’re not moving their faces in random ways. They’re moving them in ways that are specific to the situation.” Read the whole story: The Washington Post

Kolkata: State Transport minister Suvendu Adhikari took stringent measures to check “atrocities” of a section of auto-rickshaw drivers in Behala along with announcing the launch of more buses in the area. The steps have been taken to ensure that people of Behala do not face any inconvenience in the absence of the Majerhat bridge. Adhikari held a meeting on Wednesday and set up an eight-member committee comprising representatives of auto-rickshaw unions, local councilors, traffic cops and Officer-in-Charge of the local police station. The committee members will ensure that no auto-rickshaw drivers charge fare arbitrarily. Moreover, additional 80 buses will be made operational in phases on different routes including M15, 3A, 4C, C8, M16 and M17.
Kolkata: The Market department of Kolkata Municipal Corporation has found four markets owned by individual or joint owners in the city in wretched condition, two of them with poor firefighting mechanism.A team has been formed with officials of the department, Kolkata Police, CESC and Fire Services department, after the fire incident at Bagree market in Burrabazar on September 16. The team has been given the responsibility to examine the condition of not only the municipal markets but also those owned by individual owners. Also Read – Rain batters Kolkata, cripples normal lifeThe first visit of the team was at Entally Market in October and following this, the team had visited four markets by individual owners – the Harisaha Market near Khanna Cinema in North Kolkata, the Srimani Market at Amherst Street, AC market at Shakespeare Sarani and Treasure Island in Esplanade. A senior official of KMC’s Market department, on condition of anonymity, said that Harisaha Market is in extremely poor condition. “This market is open only during weekends, at the ground floor of the four-storeyed building. The roof of the building is also occupied by sellers. Around 20,000 people visit Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedthis market and so, if the roof collapses, it may lead to a disaster and loss of lives. The market building that mainly houses garment shops, is in urgent need of repair,” the official said. The KMC has served the notice of dangerous building some time ago but the owner has remained indifferent. There is a single fire extinguisher in the market and no water source. The entry and exit routes are extremely narrow and the traders lay their wares blocking space for movement. The road leading to the market is also narrow, posing difficulty to fire tenders if there is a fire incident. The condition of Srimani Market is no better but there is available space for movement of fire engines. The owners of both these markets have been cautioned and asked to take steps for repair. The AC Market at Shakespeare Sarani and Treasure Island are crammed for space and the entry and exit routes are often blocked by goods for sale. “The firefighting mechanism of these markets have been found to be satisfactory. The authorities have been asked to take measures to free space for movement,” the official added. The final report of the five markets will be prepared by the civic body after they receive the report from the police and Fire department and then submitted to the state government. There are around 358 markets in the city that include municipal ones and those owned by individual or joint owners. More such drives will be held after Jagadhatri Puja, with the target to cover all these markets.
