Using data from nearly 2 million people and 8 million phone calls over the course of a year, physicist Cesar Hidalgo from the University of Notre Dame and sociologist Carlos Rodriguez-Sickert from the Pontifical Catholic University of Chile have investigated the persistence of relationships within the cell phone network. Somewhat intuitively, they found that the leading cause of persistent relationships is reciprocity – returning a friend´s call. Further, they could use these characteristics to predict the nature of relationships in the future.As the researchers explain in their study, the persistence of the connection between two individuals is a measurement of how often they call each other. The scientists analyzed 15-day intervals, and determined if the two callers made contact within each interval. The greater number of these chunks of time in which contact occurred, the higher the pair´s persistence value was.The scientists found that the majority (60%) of ties between two callers lasted for just one 15-day interval. The next 20% of ties disappeared slowly throughout the course of the year, and the remaining 20% persisted for the entire one-year period. The results showed that the strongest factor determining persistence values was when individuals returned calls to each other. When links were reciprocated, those links had a greater chance of persisting for longer time periods. Also, when an individual´s connections had connections among themselves (when a person´s friends knew each other), his or her own connections lasted longer. The results also revealed insight into “social butterflies” – individuals with a high number of links. “One result that I thought was somehow not so intuitive was the trade-off between the degree (number of links) of a person and the persistence of its ties,” Hidalgo told PhysOrg.com. “It has been known for a long time that some people are much more connected than others, yet it was not known whether these highly connected individuals also had a larger number of strong connections. While time constraints may force people with more ties to be less persistent on average, the data also showed that, in absolute terms, people with more ties also have a greater number of persistent ties than those less connected. Highly connected individuals are not trading quality for quantity; rather, they appear to be more socially expressed in both the numbers of links and the persistence or strength of them.” By knowing the characteristics of persistence, the researchers could look at the features of the network for the first 15 days, and predict what the network would look like in the future. Since social connections play a role in areas such as collective decision making and consumption, predicting these connections might help researchers predict some of society´s actions. For example, measuring the persistence of a person´s social ties might open a new dimension for marketing segmentation strategies.”One area which is interested in new ways of characterizing individuals is marketing,” Hidalgo said. “To more effectively market their products, companies have traditionally segmented the targeted population by age, gender, ethnicities and socioeconomic status. As data on the social structure becomes increasingly available, it becomes possible for companies to categorize people based on their local structure on the social network. “This opens a new layer of information that cannot be accessed otherwise. The social structure surrounding an individual is likely the result of its behavior and personality, hence is likely to carry more relevant information than its age and gender. The persistence of a person´s social relationships is a dynamical measure that can be used to tell us how strongly a person is connected to its peers. It could indicate a level of respect or authority that cannot be captured by purely structural measures, such as the number of links or the density of its social structure.”More information: Hidalgo, Cesar A. and Rodriguez-Sickert, C. “The dynamics of a mobile phone network.” Physica A 387 (2008) 3017-3024.

LowBudget Fusion Reactor Could Generate Energy within a Decade

first_img Citation: Low-Budget Fusion Reactor Could Generate Energy within a Decade (2009, August 4) retrieved 18 August 2019 from https://phys.org/news/2009-08-low-budget-fusion-reactor-energy-decade.html General Fusion’s reactor design consists of 220 pistons that simultaneously ram a metal sphere. This creates a shock wave inside the sphere, so that plasma rings in the center create a fusion reaction. Credit: General Fusion. ITER nuclear fusion reactor to be built in Southern France This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. General Fusion has recently raised enough financial support – $13.5 million – from public and private investors to start the project. Rather than using expensive superconducting magnets (tokamaks) like the $14-billion ITER project in France or powerful lasers like those used by the Lawrence Livermore National Laboratory in the US, General Fusion plans to try a relatively low-tech approach called magnetized target fusion.The reactor consists of a metal sphere with a diameter of three meters. Inside the sphere, a liquid mixture of lithium and lead spins to create a vortex with a vertical cavity in the center. Then, the researchers inject two donut-shaped plasma rings called spheromaks into the top and bottom of the vertical cavity – like “blowing smoke rings at each other,” explains Doug Richardson, chief executive of General Fusion.The last step is mainly well-timed brute mechanical force. 220 pneumatically controlled pistons on the outer surface of the sphere are programmed to simultaneously ram the surface of the sphere one time per second. This force sends an acoustic wave through the spinning liquid that becomes a shock wave when it reaches the spheromaks in the center, triggering a fusion burst. Specifically, the plasma’s hydrogen isotopes – deuterium and tritium – fuse into helium, releasing neutrons that are trapped by the lithium and lead mixture. The neutrons cause the liquid to heat up, and the heat is extracted through a heat exchanger. Part of the resulting heat is used to make steam to spin a turbine for power generation, while the rest goes back to recharge the pistons. The biggest challenge with the design will likely be showing that the technique actually works; no one has ever demonstrated that spheromaks can be compressed enough – while maintaining their donut shape – to create fusion. The design also takes advantage of digital control technologies that have only recently been developed, which are required to ensure that all 220 pistons strike the sphere at once. General Fusion has just started developing simulations of the project, and hopes to build a test reactor and demonstrate net gain within five years. If everything goes according to plan, they will then build a 100-megawatt prototype reactor to be finished five years after that, which would cost an estimated $500 million.According to fusion experts interviewed in MIT Technology Review, the design will likely face many challenges, but the idea is scientifically sound. As Ken Fowler, professor emeritus of nuclear engineering and plasma physics at the University of California, Berkeley, explained, the culture of a private startup might enable the process to proceed more quickly, with less worry about potential risks.via: MIT Technology Review© 2009 PhysOrg.com (PhysOrg.com) — Currently, most nuclear fusion power plants are large, expensive projects that will take decades to benefit from. But a startup company in Vancouver, Canada, called General Fusion is taking the fast track to fusion, with a plan to build a working prototype fusion power plant within the next decade at a cost of less than a billion dollars.

Ancient fish hooks found on Okinawa suggest earlier maritime migration than thought

first_img Journal information: Proceedings of the National Academy of Sciences Researchers have been excavating at the Sakitari cave site since 2009 and have now found what they believe to be evidence of people finding a way to survive on the resource-limited island—fish hooks that would allow them catch live protein-laden prey. Prior research has suggested that humans have been visiting the island for approximately 50,000 years, but until now, there was little evidence of people staying on the island for long periods of time—at least until the modern era. But this new evidence suggests that people may have been living on the island continuously for the past 23,000 years—back to the time when the fish hooks (which were fashioned out of sea snail shells) were being used.In addition to the fish hooks, the researchers also found evidence of other food that had been eaten by the early humans such as frogs, birds, small mammals and even eels—much of it had been charred, suggesting humans had cooked them first. Prior to this latest report, researchers working in the cave had found human skeletal remains, beads crafted by the early people living there and what some believe might have been a grindstone. Interestingly, archaeologists have also found the remains of cooked lobster appearing to be of the size that would have been taken in the fall—the prime time for lobster fishing, as that is when they taste the best.The fish hooks represent an advancement in maritime technology, one that was necessary for the spread of people across the islands that dot the world’s oceans—they suggest that people were able to spread to a much wider geographical zone earlier than has been thought. The team also reports that they have found some other artifacts that might suggest people have been living on Okinawa going back as much as 35,000 years. (Phys.org)—A large team of Japanese researchers affiliated with multiple institutions working at a dig site on the south side of the island of Okinawa has found what are believed to be the oldest examples of fishing hooks ever unearthed. In their paper published in Proceedings of the National Academy of Sciences, the team describes the fish hooks, other artifacts they found and why they believe their findings are challenging conventional views of maritime adaptations.

Advanced maritime adaptation in the western Pacific coastal region extends back to 35,000–30,000 years before present, Proceedings of the National Academy of Sciences (2016). DOI: 10.1073/pnas.1607857113AbstractMaritime adaptation was one of the essential factors that enabled modern humans to disperse all over the world. However, geographic distribution of early maritime technology during the Late Pleistocene remains unclear. At this time, the Indonesian Archipelago and eastern New Guinea stand as the sole, well-recognized area for secure Pleistocene evidence of repeated ocean crossings and advanced fishing technology. The incomplete archeological records also make it difficult to know whether modern humans could sustain their life on a resource-poor, small oceanic island for extended periods with Paleolithic technology. We here report evidence from a limestone cave site on Okinawa Island, Japan, of successive occupation that extends back to 35,000−30,000 y ago. Well-stratified strata at the Sakitari Cave site yielded a rich assemblage of seashell artifacts, including formally shaped tools, beads, and the world’s oldest fishhooks. These are accompanied by seasonally exploited food residue. The persistent occupation on this relatively small, geographically isolated island, as well as the appearance of Paleolithic sites on nearby islands by 30,000 y ago, suggest wider distribution of successful maritime adaptations than previously recognized, spanning the lower to midlatitude areas in the western Pacific coastal region.

Higher precision measurements show proton mass less than thought

first_img More information: High-precision measurement of the proton’s atomic mass, arXiv:1706.06780 [physics.atom-ph] arxiv.org/abs/1706.06780AbstractWe report on the precise measurement of the atomic mass of a single proton with a purpose-built Penning-trap system. With a precision of 32 parts-per-trillion our result not only improves on the current CODATA literature value by a factor of three, but also disagrees with it at a level of about 3 standard deviations. (Phys.org)—An international team of researchers has developed a new way to measure the mass of a proton and found the particle to be approximately 30 billionths of a percent less than previously thought. The group has written a paper describing their process and results and have uploaded it to the prepress server arXiv. Explore further Improved measurements of antiproton’s magnetic moment deepen mystery of baryonic asymmetry Sketch of the trap setup. The trap tower includes two separate storage traps (ST-I, ST-II), the measurement trap (MT) and a reference trap (RT) for magnetic field monitoring, which is presently not used. Ions are created in-situ using a mini-EBIT. By shuttling the ions between the storage traps and the MT, the time between successive measurements is minimized. Individual superconducting detection circuits for the proton (blue) and for the carbon ion (red), allow measurements at the identical electrostatic field configurations and thus guarantee the identical position and magnetic field. Credit: arXiv:1706.06780 [physics.atom-ph] Citation: Higher precision measurements show proton mass less than thought (2017, July 5) retrieved 18 August 2019 from https://phys.org/news/2017-07-higher-precision-proton-mass-thought.htmlcenter_img Journal information: arXiv © 2017 Phys.org For some time now, the atomic mass of a proton has been an accepted standard measurement used to calculate other physics properties. Now, it appears researchers may have to revisit some of those entities as the most accurate ever measurement of the mass of a proton shows less mass than has been believed.In this new effort, the researchers fired an electron beam at a selected target atom held in a chilled vacuum chamber, releasing a proton. The group was then able to isolate the proton in a Penning trap, which is a device that creates both an electronic and magnetic field. Inside the trap, the proton moved in circles—measuring its velocity allowed the researchers to calculate its mass, which was 1.007 276 466 583(15)(29) atomic mass units. The 15 in parentheses represented the statistical uncertainty and the 29 that followed represented the systematic uncertainty.The group reports that their technique was three times more precise than any other technique used to date.Others have noted that making more precise measurements of protons and other particles could explain some of the big mysteries in physics—such as why the radius of a proton has been found to be smaller than theory has suggested, or why there is more matter than antimatter. It could also help research efforts exploring apparent discrepancies between protons and antiprotons.The research group has made clear its plans to continue refining its measuring technique—their goal is to improve the measurement for a proton by a factor of six. Meanwhile, if others are able to reproduce the work by the team, the new measurement could be included in the newest CODATA, which is scheduled for publishing in just a few months.

Compensate human trafficking victim HC to state legal body

first_imgKolkata: The Calcutta High Court has set aside denial of compensation to a victim of human trafficking by West Bengal State Legal Services Authority (SLSA) and directed it to pay the same to her. Justice Rajasekhar Mantha said compensation is awarded under the Victim Rehabilitation Scheme of 2017 as the fundamental rights of the victim under Article 21 (Right to Life) have been in fact violated. Denial of compensation to such victim would continue such violation and perpetrate gross inhumanity on the victim in question, Justice Mantha said. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killed Such rehabilitation is not dependent on the pace in which either the investigation is conducted or the trial is carried on, the court said. “The object and purpose of the scheme of 2017 is that a victim of a serious crime, especially a woman, needs urgent and immediate attention and both physical and mental rehabilitation,” Justice Mantha observed. Directing that the quantum to be disbursed either in one go or in intervals shall be decided by the SLSA, the court said that the victim shall be entitled to claim and justify the amount of compensation she requires at a given point of time “not exceeding the amount of compensation payable to her in entirety”. Also Read – Naihati: 10 councillors return to TMC from BJP Justice Mantha, while passing the order recently, also directed the state CID, which is handling the case, to conduct the investigation expeditiously and apprehend the absconding persons. The court directed the SLSA that it would assess the compensation payable to the victim and make over the same to her within 10 days of communication of the order. The girl, a victim of human trafficking, was rescued from Maharashtra’s Pune and brought back to West Bengal. While two accused persons were arrested, two others are absconding. “The girl had filed an application under the West Bengal Victim Compensation Scheme 2017, but was denied the relief by a district legal services authority and an appeal before the SLSA was also rejected,” her counsel Kaushik Gupta said. She moved the high court challenging the rejection of her appeal by the SLSA. Passing the order, the high court observed that the object and purpose behind the scheme is compensation to the victim primarily for the purpose of rehabilitation. A victim can claim rehabilitation during the pendency of the trial, prior to its commencement or upon conclusion of a trial as per the existing laws, the court noted. The SLSA rejected her claim on the ground that both conditions, one being the accused not being traced or identified, as well as trial not having commenced, are required to be satisfied to entitle the petitioner for compensation. The court said that the rejection by the SLSA on such grounds cannot be sustained in law. Justice Mantha referred to a July 2017 judgement by a co-ordinate bench of this high court that said the Victim Compensation Scheme requires and enforces the directive principles enshrined in the Constitution of India under Article 38 which obligates the state to render social justice to its citizens. A citizen cannot be asked to forfeit the right to live with dignity just because such citizen has become a victim of an act of crime, the earlier judgement said, adding that “the state is obliged to protect the life and property of its citizen”.last_img read more

Performing freedom

first_imgIf in the beginning was the ‘word’, theatre paved the way for the word to be used meaningfully. The most distinctive quality about theatre, one that distinguishes it from other art forms, is the interactive relationship between actor and audience, the engagement in a communal activity. What is of consequence is how we use this community creating quality of theatre in the contemporary world, how we shape the interactive and communal nature of the theatrical experience to make it a forceful political agency.  Also Read – ‘Playing Jojo was emotionally exhausting’In a world when things have really fallen apart in the Yeatsian sense, it is important to empower ourselves as best as we can. In theatre, that can happen when the audience does not cling to its passive role as spectators who merely watch, but rather transform into a community of individuals who can look beyond their prescribed roles within not just the theatrical space but also in the world beyond theatre. Only then can the true role of theatre in the drama of life unfold itself. Also Read – Leslie doing new comedy special with NetflixIn 2005, when Juliano Mer Khamis was a well known actor in Israel, he was asked by Jonatan Stanczak, a Swedish/Israeli activist, and Zakaria Zubeidi, former commander of the Al-Aqsa Brigade in Jenin during the Second Intifada, to help co found the Freedom theatre at Jenin , a camp with 16000 registered Palestinian refugees in the north of the West Bank. This theatrical space aimed to provide to children and youth a place where they could articulate their feelings without any scaffolding, challenge existing realities and create at least an imagined world where they would be free from any kind of bondage. Juliano had inherited his passion for theatre and a spirit of resistance from his mother, Arna. She was a human rights activist who laboured tirelessly to establish centres of art and education for Jenin’s children, spaces where they learnt to negotiate with the trauma caused by the violence they saw around them. She initiated The Stone Theatre but that was literally razed to the ground in 2002. It was only fitting that Juliano carried forward her vision of a theatre that could become an ameliorative space. It is now four years since Juliano Mer Khamis was assassinated brutally in 2011 as he was leaving Freedom theatre by masked gunmen. The assassins roam at large as they were never identified or caught. But Freedom Theatre carries forward the torch lit by Juliano, undeterred by the interrogation that the Palestinian members are subjected to from time to time by the Israeli Defence Forces. The question is, why was Juliano such a threat? Why was it necessary to eliminate him? Why do the Israeli Defence Forces try to intimidate those who are attached to Freedom Theatre in any way?   Because here was a man who saw in theatre and culture a means to resist oppression even as it ushered in a space where people could realise their creative potential. Here are people who are not only transformed from mere spectators to actors but in fact to what they call themselves- ‘freedom fighters’. And here is a theatre that though interested in improving the standards of the performing and visual arts in Jenin and breaking its isolation from the larger Palestinian  and global communities, has a bolder and more specific intent: to promote active resistance to Palestinian occupation. Such a theatre is bound to make the Establishment insecure. Especially since this Theatre is quite literally a mobile one: the Freedom Bus is the annual tour of locals, internationals and theatre staff through Palestine and which uses interactive theatre performances, drama workshops, live musical events, and storytelling to reach out to its audience .In fact the Freedom Theatre is a space that allows its members to use an ensemble of artistic tools to decolonise the minds of people; hence their Drama in Education trains Palestinian educators in the use of drama as a pedagogical tool.  Everything is geared to a visual auditory experience that enables the audience to perceive and inculcate exactly those myths to which the values associated with a sense of national identity are propagated through the plays staged by Freedom Theatre. By attacking Freedom theatre, the Israeli Defence Forces have made it very clear that they will not tolerate any community that attempts to question their absolute authority. They endeavour then to silence the voices and minds that are subversive.  What kind of plays does Freedom Theatre stage? Iconic ones include adaptations of George Orwell’s Animal Farm, Lewis Carroll’s Alice in Wonderland and Ghassan Khanafani’s Men in the Sun. These mirror and critique Palestinian society. Apart from these adaptations, Freedom theatre has some original plays such as Stolen Dreams, Fragments of Palestine, and Sho Kman(what else?). Recently, Jana Natya Manch, the well known Delhi based street theatre group has forged ties with Freedom Theatre. The two companies intend to collaborate and stage their joint ventures across cities like Mumbai.last_img read more

Just eat well, exercise well and be determined.”The team will train in Scotland from September 1 to 9. After that, they will go to London and return to India.”In December, we will fly from South America and after reaching Antarctica we will be taken to a special camp called Union Glacier from where we will head for the magnetic pole.” Buch thanks her parents for their encouragement and says: “This was totally unexpected. There is a lot of positive energy that has been generated within the team and I’m enjoying every bit of it. I’m trying to keep myself fit and my main focus now is this expedition. It’ll definitely be a once-in-a-lifetime opportunity.”Mitra says she is super-excited and overwhelmed with this opportunity. Regarding the challenges, she says: “I am a trained mountaineer and recently underwent rescue training to avoid any difficult situation during rock climbing and mountaineering.”The expedition, aptly titled the “Polar Maidens,” will highlight how ordinary women can achieve the extraordinary, expand their horizons and inspire others to explore their strengths.last_img read more

Dog Poop – The Secret Ingredient in Victorian Leather

first_imgBack in the day, dog poop was actually a valuable resource to leather makers. So the coats people wore, the handbags, briefcases, and all the leather goods they used were thanks, at least in part, to dog dung. Not surprisingly, entrepreneurial folks also found a way to benefit from this need for poop by keeping their streets and alleyways free of the brown mess, because it held currency for them at local tanneries.Tanning, c. 1880.Long before the days of modern manufacturing with chemicals and clean environs, tanneries had such a powerful smell that they were located outside of the town.But in London, for example, people knew that poop was an important part of the tanning process — so off it went, effectively helping keep the streets poop free. Dog feces contain enzymes that break down collagen in hides, part of the tanning process called “bating.”Leather Tanners in Morocco. Photo by Peter van der Sluijs – Own work CC BY-SA 3.0It’s no wonder the New Research Encyclopedia refers to tanning as “noxious,” and “an odoriferous trade.”Skins arrived at a tannery bloody and wet with whatever animal remains still clung to them. First, they were soaked in water to clean them. Then came urine to help make them pliable enough that the hair could be removed with knives.And that’s where the poop came in. It may sound wholly unappetizing now, but at a time when there were no ready-to-use chemicals, the lovely sheen of fine leather goods was achieved by soaking the hides in a mixture of water and dog poop. Or pigeons – their poop was used too.Tanner, Nuremberg, 1609.British writer, artist, and librarian Julian Walker discussed the subject in his article, “More Poo, And Some Words on Tanning.” Walker confirmed that, “dog excrement was not an ingredient in tanning until the second half of the 18th century,” but until chemicals were introduced into tanning in the mid-20th century, it was a key step in the grueling process.Which begs the question: could we solve the modern problem of dog poop on our streets by turning to a very old method? Not in tanning, of course; best to leave that to the professionals and the chemicals. But what about other uses for it?Woman tells her Dog She Ate All His Halloween Candy.Some individuals have taken note of the forward-thinking ways being used to motivate dog owners to pick up after their pets. And in some rather unexpected places, too.Terra, a telecommunications company in Mexico City, installed bins across the city’s parks into which people could put put poop in exchange for free Internet service.Pet waste sign at the park in Miami.Jonathan Fincher, in the May 3, 2012 edition of the New Atlas, described the innovation as a win-win for everyone: the firm gets free P.R., the city gets tidier parks, and dog owners get free Wi-Fi in exchange for picking up after their pets.In his article, “Mexican Internet Company Exchanges Public Wi-Fi For Dog Poop,” Fincher wrote, “It may sound like a bizarre concept, but if it motivates people to keep their public spaces cleaner, it could prove to be a good method, in the long run.”Sign ordering owners to clean up after pets, Houston, Texas, 2011.No doubt, the limitations of poop’s uses are set only by our imaginations and the “yuck” factor. But if we can offer rewards for diligent dog owners, maybe one-day dog poop in the streets will be much more than a societal nuisance.Read another story from us: Monks, Monkeys, and Cappuccino – They Have More in Common than You KnowMaybe that feeling of “gross!” we get when we step in it can be replaced by a feeling of, “look what I found!” Is that such a stretch? Perhaps, but that’s probably what they said to the guy who invented the elastic band.last_img read more

Colins Herd Hierarchy after NFL Week 8

first_img Advertisement 8. Kansas City Chiefs – The Chiefs defense has been a problem, which is why they’ve dropped to 8 after holding the top spot for several weeks earlier in the year. They’re 30th in the NFL in yards per play allowed, and have given up 29 or more points in 4 of the last 5 weeks.Offensively, K.C. leads the NFL in yards per play (6.26), and Alex Smith has 16 touchdowns and 0 INT’s through 8 weeks, but they’ve been held under 100 yards rushing in their last 3 games after rushing for more than 100 in their first 5. They need to get their defense figured out and the biggest question is if they can get it done in the playoffs. 4. Dallas Cowboys – Colin still has the Cowboys at 4, despite the apparent loss of Ezekiel Elliott for 6 weeks because he loves their offensive and defensive line play. Dallas ranks 2nd in rushing offense (150.6 YPG), 5th in scoring (28.3 PPG), but will need a running back by committee to replace Elliott, who is tied for 1st in rushing touchdowns (6), and 3rd in total scrimmage yards per game (128.6). Colin thinks they can still get production from Darren McFadden and Alfred Morris behind their mashing o-line until Zeke returns.Demarcus Lawrence leads the NFL with 10.5 sacks, and as a team Dallas ranks 5th in the NFL with 25 sacks. The Dallas D has been one of the most surprising units in the NFL. Dak will need to step up with the absence of Elliott. 2. Philadelphia Eagles – The Eagles picked up Jay Ajayi, which gives them a scary downhill running back combo, along with LeGarrette Blount. Carson Wentz is tied for the NFL lead with 19 touchdown passes, and as a team they rank 1st in the NFL in time of possession (33:57), scoring differential (+76), and are scoring touchdowns on 68% of their red zone trips.They lead the NFL in rushing defense, allowing just 70.4 yards per game, and are only allowing opponents to convert 31% on third downs. Philly is a contender. 9. L.A.  Rams – The Rams are still good enough to make the Top 10, but they can’t seriously contend because Jared Goff isn’t there quite yet. In his last four games, Goff is completing just 53.9% of his passes, with 4 TD’s, 3 INT’s, and a passer rating of just 74.2.Colin loves their pass rush, run game and they may have the best special teams in the NFL, but they aren’t ready to make a deep playoff run this year. Seattle Seahawks – The Seahawks are coming off an impressive win over a tough Houston team, and just bolstered their below average o-line by picking up All-Pro tackle Duane Brown from them in a trade.Since Week 3, Seattle ranks 1st in passing offense (318.6 YPG), 2nd in total offense (411.0 YPG), and 3rd in scoring (30.8 PPG). Russell Wilson is 2nd in the NFL with 286.9 passing yards per game. Seattle has the pieces to get it done and win it all. Colin moves them up to 1 this week.The Seahawks are the best team in the NFLRT if you agree with @ColinCowherd pic.twitter.com/JO7axtBpFL— Herd w/Colin Cowherd (@TheHerd) October 31, 2017 5. Pittsburgh Steelers – The Steelers have turned it around after a slow start because they’re pounding Le’Veon Bell. During their 3-game win streak, Bell is averaging 30.7 rushes per game and 129.7 yards per game, and in his career, Pittsburgh is 19-0 when he gets 23 or more carries in a game.Defensively, Pittsburgh is 1 of 2 teams to have multiple sacks in all 8 games, and has the 3rd best scoring defense in the league (16.4 PPG). 3. New England Patriots – This New England offense may be the deepest, personnel wise, they’ve had in the Belichick era. They’re 1st in total offense (411.1 YPG), 1st in passing offense (302.1 YPG), and Tom Brady leads the NFL in passing yards per game (317.6), and is 2nd in passer rating (106.5).They’re still terrible defensively, ranking 32nd in yards per play allowed (6.59), total defense (417 YPG), and passing defense (295.5 YPG Allowed). Colin still thinks Brady and Belichick can get it done in the playoffs if they can just get the defense to average. 7. New Orleans Saints – New Orleans is the one of the surprise teams in the NFL because they’re playing real defense and running the ball.The Saints have 11 takeaways during their current 5-game win streak with at least 1 turnover in each of those games, and are only allowing 4.67 yards per play over that span. They’re also averaging 138 rush yards per game during the streak, with 7 TD’s on the ground. Drew Brees and Sean Payton have turned it around thanks to their new found balance. Every Tuesday during the NFL season, Colin puts out his Herd Hierarchy NFL power rankings, and there’s movement after Week 8. This week, the Rams drop, the Vikings are back in, and there’s a new #1.Here are his Top 10 teams after Week 8:10. Minnesota Vikings – Colin likes the Vikings, even with backup Case Keenum under center, and it’s mostly because they have one of the best defenses in the league. The Minnesota D is ranked 3rd in total defense (282.1 net YPG), 4th in rushing defense (81.4 YPG), scoring defense (16.9 PPG), and elite pass-rusher Everon Griffen is tied for 2nd in the NFL with 10 sacks.The Vikings offense may not be spectacular, but because they rank 5th in the league in time of possession (31:27),  it gives them a chance to win. They’d be higher if they had an above average quarterback. 6. Houston Texans – Houston and Deshaun Watson have been impressive, but the loss of All-Pro tackle Duane Brown in a trade with Seattle hurts. They’ve allowed a QB pressure on 43.2% of dropbacks, which is the worst in the NFL. Brown would have helped shore up the protection, but now he’s gone.Since Will Fuller returned in Week 4, Watson is averaging 9.44 yards per pass, with 16 touchdowns, 5 interceptions, and a passer rating of 116.0. Colin likes the roster, weapons and Watson has exceeded all reasonable expectations.last_img read more

Internet Security

first_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Brought to you by PCWorld 4 min read ProsExcellent performerConsRough interfacePricing :Amazon.com $69.99BitDefender Internet Security 2008 BitDefender was an excellent performer among security suites, but it’s best for experts who don’t need guidance regarding security extras and pop-up alerts and who don’t mind therough interface.BitDefender Internet Security 2008 ($40 for one PC, $50 for three PCs) pairs shining success with disappointing failure. It outperformed every other suite in crucial malware detection tests, unmasked every rootkit sample, and finished second among the eight suites evaluated for our “All-in-One Security Suites: Tried and Tested” roundup on a separate spyware and adware detection test.But this stellar performance behind the scenes was seriously marred by an unpleasant user experience. From aggravations with the initial installation to difficulties with warning pop-ups, BitDefender’s flaws are hard to brush off.BitDefender did extremely well when subjected to AV-Test.org’s 674,589 inactive malware samples, detecting 98 percent of them. It also did the best job of detecting new, unknown malware in heuristics tests, with a 29 percent catch rate using one-month-old signatures. And it also tied for first with Kaspersky Internet Security 7.0 for the fastest response (0 to 2 hours) to malware outbreaks.The suite detected all six inactive rootkit samples, though its efforts to disinfect one of them (Vanquish) crashed our test computer. BitDefender caught 97 percent of inactive spyware and adware samples, too, but it was our test group’s second-worst offender at flagging false positives–though its 0.06 percent rate for false positives lies within an acceptable range.As an infection remover, BitDefender didn’t hold up as well. It successfully sanitized the files related to four out of five infections, but it completely failed to remove changes to the Windows Registry. Though they pose less danger of serious harm to your system than malware files, altered Registry entries can interfere with the smooth running of your PC.BitDefender’s firewall successfully masked a protected PC against outside scans, but it displayed needless warnings when the Firefox Web browser tried to access the Internet. That program should be on any firewall’s list of known (and approved) applications.The suite offers a good array of secondary features, including antiphishing, parental controls, antispam, and data privacy. But these extras need polish. The browser-based antiphishing tool didn’t block any sites until I enabled the feature’s heuristic detection, which is off by default. When I enabled parental control for other users, I wasn’t prompted to set a program password–but if you fail to do so and you set up your kids’ accounts with administrator rights, they’ll be able to turn off the parental controls.The antispam features currently tie into Outlook and Outlook Express only; a few other suites tie into Windows Mail and Thunderbird as well. The suite’s Identity Control data privacy features requires that you manually enter any data (such as credit card numbers) that you want to prevent from being sent out on the Internet. Though that practice is fairly standard among suites, BitDefender pushes you to create the definitions on first use, and it’s not easy to figure out how to bypass this step.BitDefender’s warning pop-ups did a poor job of guiding us through the steps of removing a detected e-mail worm (Warezov). The pop-up alert had options for ignoring, quarantining, or deleting the file. But perhaps because ther malware was lurking inside a .zip file, the security suite’s default option was to ignore the infection. Choosing to quarantine the archive failed, but rather than alerting me to the failure. the program just popped up the same window without the quarantine option. Choosing delete finally worked.Unlike every other suite we tested, BitDefender doesn’t provide contextual help links that take you straight to the parental control help section if you click ‘Help’ while changing those settings, for example. Also, BitDefender asked again for the program registration code and registration information when we logged on as another user on the same PC. The company acknowledged that this is a program bug it intends to fix.If BitDefender’s interface and warnings were anywhere near as good as its virus detection engine, the suite would be easy to recommend. But its confusing pop-ups, program bugs, and high false positive rate make it best suited to a user who has strong technical skills and can at times make the right security choices without guidance from the software.– Erik Larkin November 29, 2007 Enroll Now for Freelast_img read more

Google Unveils New PlayPause Controls for Chrome How to Try Them Early

With Global Media Controls, all of your audio-playing tabs are neatly packaged so you can quickly control what comes out of your speakers. The play/pause icon will reportedly be added to Chrome’s desktop version on Windows, Mac and Linux, according to ZDNet. There’s no word yet on when it will arrive or whether it’ll make an appearance on Chrome OS, but we expect to see it on Google’s desktop OS once the bugs are all worked out.How to use Google Chrome’s play/pause controlsIf you want to try it yourself, just download Google Chrome Canary and enter the experimental feature page at chrome://flags/. From there, search for “Global Media Controls” and choose “Enable.” You’ll have to restart the browser. Once it reloads, you’ll see a play icon on the right side of your toolbar. When audio is playing — whether a movie, TV show or song — the source will appear in a drop-down box with the option to pause, skip or go back. As I mentioned, Google Chrome Canary crashed nearly every time I tried testing it. Despite those problems, I remain hopeful that it makes it to the official browser so I can quickly turn off auto-play ads and listen to my music without any disruptions. 40 Best Google Chrome Extensionscenter_img by Taboolaby TaboolaSponsored LinksSponsored LinksPromoted LinksPromoted LinksYou May LikeKelley Blue Book5 Mid-engine Corvettes That Weren’tKelley Blue BookUndoGrepolis – Free Online GameGamers Around the World Have Been Waiting for this GameGrepolis – Free Online GameUndoForbes.comCrazy Rich Asians for RealForbes.comUndoVerizon WirelessThis new phone will blow your mind.Verizon WirelessUndoTODAYPolice Identify Girl Licking Ice Cream Tub In Viral VideoTODAYUndoMy Food and FamilyHealthy, Homemade Drunken Thai Noodles In Just 20 MinutesMy Food and FamilyUndoAdvertisement Phillip Tracy is a senior writer at Tom’s Guide and Laptop Mag, where he reviews laptops and covers the latest industry news.

Check your passwords against the Pwned Passwords database

first_imgCheck your passwords against the Pwned Passwords database by Martin Brinkmann on February 22, 2018 in Security – 21 commentsIs a password that you use actively to protect an account secure? The question is difficult to answer as it depends on your definition of secure.Secure can mean, among other things, that it cannot be cracked in reasonable time, or that it is not already on a publicly accessible password list.Pwned PasswordsThe Pwned Passwords database of Have I Been Pwned has been updated recently with new password data sets.The service accepts a password and reveals whether it was found on any of the lists that powers the service’s database.All you have to do is type a password to find out whether it is available in the clear-text format on a public password dump list.Some users may have reservations when it comes to typing passwords that they use on a site on the Internet. That site, in theory, could use the information for malicious activity. While it requires a username, usually that goes along with it, adding the password to a list to run dictionary attacks against services could have negative consequences for the user who entered it on the site.That’s one reason why you may download the entire database to your local system. It is available as a zipped torrent file; the torrent file has a size of 8.8 Gigabytes and contains a list of 501 million password hashes and password use counts. The archive extracts to a single 30 Gigabytes large text file that many text editors won’t open.Use a free program like Large Text File Viewer to open the text document on your system.You need to compute the SHA-1 hash of your passwords and may use a free program like HashCalc for that which supports the computation of hashes from text strings among other things.You’d then search the downloaded database file for that Sha-1 hash to find out if the password leaked before.Attackers may use public password lists in attacks, especially if passwords are popular.If a password is found in the database, it is advised to change it and use a password that is not found. Generally speaking, it is best to assume that any password that is listed in the database is known to attackers and should not be used anymore.Now You: How do you make sure to select secure passwords for accounts?Related articlesDashlane wants to automate passwords in 2018Encryption and Strong PasswordsKeePass 2.36: detect duplicate or similar passwordsPassword Use Study: massive reuse of passwordsYou should not be using these passwordsSummaryArticle NameCheck your passwords against the Pwned Passwords databaseDescriptionYou may use the updated Pwned Passwords database to find out whether the passwords that you use actively are on public password database lists on the Internet.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisementlast_img read more
