Caring: No one wants to follow a leader who doesn’t care about them personally. They don’t want to follow someone who doesn’t care about something that creates meaning and purpose and mission. It’s your job to care so deeply that your passion spills over and literally creates followers.Listening: Leaders spend time listening. Listening is one of the ways that you learn. You constantly take in new ideas and new information so that you can improve your own performance, and the performance of the organization and the people you lead. Great leaders know that they don’t have a monopoly on good ideas and seek them from outside themselves.Reading: Leaders read. Leaders read about the type of organizations they run. They read about leading and about other leaders. They read the news, nonfiction, and fiction. They synthesize all they read, finding connections and themes that they can use to become better, more effective leaders. You need to surround yourself with a stack of books, magazines, and papers.Thinking: Leaders spend time thinking. They literally make time to think. Even if it means they have to unplug and go offsite to have the time they need to do nothing other than engage in an internal dialogue with themselves, asking themselves questions and pondering the answers. Thinking is some of the most difficult work a leader will ever do.Helping Others Grow: Leaders help others grow. You help others find something inside themselves that they didn’t know was hidden there. Great leaders help guide the people they lead to their best performance, and they challenge them to stretch beyond anything they believed possible. You have to see something inside the people you lead and help them become that.Shaping Values: Shaping values is what allows the leader to share what is important, what matters, and what is necessary for the people and the organization they lead to live its purpose. Find and tell stories to bring your values to life. Find a way to catch people doing things right and shine a light on them so that they can serve as an example to others. And protect the positive culture you build from anything that might damage or destroy it.Envisioning: A leader must provide a vision of the future. You have to know where you are taking those that follow you, and where your organization is going. That future needs to be bigger, better, and brighter. It has to provide meaning and purpose. Your vision has to compel others to act and inspire them to do whatever is necessary to bring it to life.Persuading: Results are achieved by persuading others to change, to do things different, to grow. Good leaders know that they can’t make anyone do anything. They know that the most powerful tool for change isn’t demanding it but persuading people to make the necessary changes. Your formal authority is nothing compared to your moral authority and your ability to persuade others.Deciding: Leaders make decisions. You can’t afford to wait passively as events unfold around you, paralyzed by fear, and failing to act. You will get some big decisions wrong. You will only get some of the big decisions you are charged with making right. You will always have to make adjustments. Come what may, you have to make decisions.

The Man Behind the Mask”General Pervez Musharraf should quit playing hide and seek. Mullah Musharraf ‘s mask is now badly ruined. It’s time for Pervez Attaturk to come forth.” – Shaheen Niazi, on e-mailCurtain CallGeneral Pervez Musharraf is nothing if not a great actor, well-versed in the art of dissimulation,The Man Behind the Mask”General Pervez Musharraf should quit playing hide and seek. MullahMusharraf ‘s mask is now badly ruined. It’s time for Pervez Attaturk tocome forth.” – Shaheen Niazi, on e-mailCurtain CallGeneral Pervez Musharraf is nothing if not a great actor, well-versed in the art of dissimulation (“At Your Service, Sir”, October 1). He can blow intensely hot and frigidly cold in the same breath. Yet he is walking on the sharp edge of a sword-a momentary loss of balance and he tumbles down, consigned to the dustbin of history, hated and reviled by the same people who are singing paeans in his honour.- Santosh Kapoor, NoidaMusharraf has always adopted a dual role: that of a rigid fundamentalist at home and an extreme liberal abroad, but it is time to take a decisive stand on one. However, he is right in asking India to “lay off”. After all, of what use is India when he and his fellow hypocrites are adequate to destroy Pakistan?- Premchand Beura, on e-mailMusharraf’s present predicament is symptomatic of the age-old saying: “Men fall into the ditches they dig for others.”- A.U.S. Lal, KolkataThe Pakistani general cannot soar with eagles while working with turkeys. He is caught between the devil and the deep blue sea and it is only a matter of time before he is forced to step down or is thrown out in a coup.- A.S. Raj, on e-mail Changing Colours The issue of the nurses’ uniform has nothing to do with male ego or aboutthe army being a male bastion (“Nursing a Uniform Grouse”, October 1).Instead, it is about nurses trying to be something they are not – armyofficers. The fact that all nurses are females has been exploited. Hadit been about male vanity alone, there would have been strong objections to the female doctors in the army and hundreds of other women officers. – Flt-lieutenant Manisha Rao, Hyderabad advertisementMembers of the military nursing service who were wearing a white uniform since 1943 said that they didn’t like “western-styles” likeskirts and requested the army authorities for a change of uniform. Aneasy answer would have been an Indian dress but by a series ofmanipulations they tricked the authorities into allowing them the olivegreen uniform – the exclusive privilege of officers who are subject tothe Army Act. Nurses are part of the auxiliary service. It’s clear thatthey simply wanted the uniform of the officers of the armed forces.- Brigadier R.S. Randhawa, DelhiUnholy Anomaly Terrorism should be treated as a social problem (“Jehad Against the World”, September 24). Associating a religion with terrorism is objectionable. Terrorism, in whatever form, is a criminal act and no particular religion or its followers should be targeted for a condemnable act of a few insane minds.- Mohd. Amir Idrees, LucknowWhatever action US President George W Bush opts for in retaliation, his presidency will go down in history as a period of enlightenment on two counts: one, it exposed the weakness of the “world’s most dynamic democracy” in handling tightly fought elections because of the inability to count votes properly. Secondly, it showed that the world’s superpower could be flummoxed by a few well-wielded scalpels.- Devraj Sambasivan, AllappuzhaThe way India and Pakistan are going all out to offer support to the US is indicative of the fact that America is a superpower without an iota of doubt. Sadly, our Government does not possess the same capability. We allow our people to be killed in our country and do nothing about it, except go on the defensive and launch monologues. Yet we go out of the way to extend logistical support to a foreign country. I wonder if Pakistan would have pledged similar support to India in case of such a strike here.- Prateek Kaul, PuneWhat about America’s own involvement in various terrorist activities in other countries conducted without fear of a backlash from the oppressed (“Fusion Reaction”, September 24)? It is like a pot calling the kettle black. This attack, although condemnable, has demonstrated that it is brain power, rather than money power, that reigns supreme.- Sophia Ajaz, DelhiPotent Supplement Sri Lanka’s win shows how planning and preparation remain the bedrock of success in sports (“The Will to Win”, September 17). The free hand that administrators in the island nation have given coach Dave What-more has already led Sri Lanka to a World Cup win. We remain oblivious of the fact that tactics must supplement talent for success to be achieved in today’s competitive sporting world.- Ranjan Sahay, Cooch BeharWith the growing frustration of cricket lovers in India, it may be pertinent to apprise the national selectors and Sourav Ganguly of an old Arab proverb: “A n army of sheep led by a lion will defeat an army of lions led by a sheep.” An apt obituary of Indian cricket.- Rathnakar Rai, on e-mail An Uncertain Future Thecontroversy surrounding the status of astrology as a science isunwarranted (“Science or Sham?”, September 17). After all, it is not asthough the UGC promotes only science subjects. Besides, all art subjects use some degree of interpretation. Does that render them irrelevant? – Sharada Kumaraswamy, on e-mail advertisementWhile science is an attempt to explain the unknown in terms ofthe known, astrology is a subject that gives indications of what thefuture holds. Thus in a certain way astrology can also be studied as ascience. It follows the methodology of science and clearly states thatwhatever predictions may be made on the basis of its data are mereindications. – K. Parameswaran, Thiruvananthapuram The damnation of vedic astrology stems from the fact that while anythingborrowed from the us becomes globalisation, our indigenous heritage isperceived as saffronisation.- Abhinandan Singh Rathor, on e-mail Ugly Encore There are striking similarities in the bureaucratic and political response to starvation deaths in two events almost 70 years apart (“Lethal Diet”, September 10). In Discovery of India, Jawaharlal Nehru had written about the 1943 Bengal famine: “Up to the last moment, the famine was denied. When it became impossible to deny, each group in authority blamed some other group.” His words ring true in the Orissa famine as well. The Government blames the starvation deaths on poisonous mushrooms and contaminated mango kernels. And all the while the Central Government washes its hands off, saying that the Public Distribution System is a state subject.- Dr B.N.S. Walia, on e-mail Not Worth Emulating Your cover story on the Arjuna Awards overlooks two important facts (“Prize and Prejudice”, September 3). First, Dronacharya is a model of what a teacher should not be. He sacrificed his best student to ensure political patronage. Secondly, Arjuna never won any contest without subterfuge. By naming our national awards after these two, these base principles have been propagated.- Dr A.K. Basu, Ranchi Negative Publicity Your story on the Uttaranchal chief minister appears to be a deliberate attempt to defame Nityanand Swami (“The Swamy of Inertia”, September 3). The statement that he has never won a popular election and has instead preferred the safe route through the Dehradun-Hardwar graduate constituency seat is mischievous. Swami was elected an MLA as a Jan Sangh candidate from the Dehradun constituency in 1969. Moreover, none of his aides is either an architect or an RSS full-timer. And Swami, as chief minister, has more achievements than putting up traffic lights in Dehradun. The worst insinuation is that Swami was nowhere around when the agitation for Uttaranchal was at its peak. As chairman of the Vidhan Parishad, he represented the hill state’s case in Lucknow as well as in Delhi.- Anil Kumar Sharma, Executive Director and Under Secretary to the Chief Minister, Dehradunadvertisement
Manchester United legend Gary Neville, didn’t hesitate to lash out against Brazilian midfielder Fred for not living up to his price tag expectations.The first season at Manchester United for Brazilian midfielder Fred has been below average, something that club legend Gary Neville has specifically pointed out this Wednesday and has stirred a bit of controversy in England.The Red Devils paid Shakhtar Donetsk a total of £50m for the player last summer with the idea that he would be essential to the club’s resurgence this season, but the reality that has struck all Mancunian fans in the face is very different to what was promised at first.Gary Neville has taken it upon himself to become the voice of all those unhappy supporters, who don’t understand why the club spent so much money on a player who isn’t top quality and has clearly become one of the biggest waste of money for the club in recent years.Many are quick to point at Jose Mourinho himself, but the relationship between the manager and vice-chairman Ed Woodward is what pushed the club to rush this transfer after the top options were rejected by the board.Jose Mourinho didn’t really have much choice on the matter, he brought the player that the club wanted to buy because they didn’t fancy spending more money than that.Neville Vs SounessNeville showing his ass here. Disappointing. pic.twitter.com/ENB7L78sgv— THE NORTH REMEMBERS. (@MidKnightGaz) November 12, 2018During The Gary Neville Podcast this week on Sky Sports, the former Manchester United player expressed his uncertainty against the Brazilian and complained about the elevated price-tag that was practically wasted during the summer because Fred hasn’t really played that much.“Fred at £50m, he started the first game of the season and he looked bright, he looked tidy – but does he look like what you would expect for £50m?” Said Neville on the podcast.“Does he change a game? Does it look like he’s going to defend your goal? Does it look like he’s going to connect back-to-front? At this moment in time, no.”“He is still developing. He’s still getting used to Manchester United and he’s coming into a very difficult position in the sense that the club aren’t the most stable at this moment in time in terms of their performance levels and the scrutiny that’s been on the club in the past three or four months.”Maguire says United need to build on today’s win George Patchias – September 14, 2019 Harry Maguire wants his United teammates to build on the victory over Leicester City.During the summer, Harry Maguire was referred to as the ultimate…“So, I wouldn’t put it all onto Fred but you have to ask the question, where was he [on Sunday] in that central midfield?”He’s not been impressed #mufc https://t.co/qPzMfLt0Fc— Man United News (@ManUtdMEN) November 14, 2018But this problem goes a lot further than the low level of performance that the player has been showing during training sessions, this has a lot more to do with the actual owners of the club who care very little about the club’s well-being as long as it keeps generating revenue.As of right now and according to Forbes, Manchester United sits pretty as the football club with the highest revenue in the world with £581 million worth of total revenue.The Glazer family won’t change the narrative or their transfer policy as long as the checks keep on coming.This will result in many more flop transfers like Fred, because the board feels like they don’t really need to spend crazy amounts of cash in order to perform relatively well on all the competitions they play.This is increasingly frustrating for people like Gary Neville, a club legend who saw the Red Devils transform into one of the most successful clubs in football history under Sir Alex Ferguson, and are currently losing their prestige because of the terrible business they make by signing players like Fred.’Does he look like what you would expect for £60 million?’: Gary Neville claims Manchester United midfielder Fred is not living up to his price tag pic.twitter.com/Sau1H7TG1Q— Lilian Chan (@bestgug) November 14, 2018What do you think is the best solution for Manchester United’s poor transfer policy?

Share your voice Reimagining the cockpit Ten years ago, CES’ automotive hall was all about speakers and stereos, but 2019 sees automakers and media providers completely reimagining what entertainment in car looks like. Audi collaborated with Disney on a project called Holoride, a VR experience for passengers that brings games and movies along for the ride. Meanwhile, Intel and WB’s AR cockpit is an augmented reality autonomous car experience that takes riders on a virtual tour of Batman’s Gotham City. Entertainment might get a whole lot more immersive in future autonomous vehicles. Intel Speaking of augmented reality, suppliers like WayRay and Valeo are busy working on ways to bring AR tech to the cars of today. Valeo’s XtraVue invisible towing system uses cameras to make a towed trailer appear transparent when viewed through an in-car display. Meanwhile, WayRay’s massive head-up display tech enables AR data to be overlaid on to a vehicle’s windshield. A different side of autonomous tech The lion’s share of CES 2019’s car-related news fell to autonomous and semiautonomous technologies that aim to make tomorrow’s vehicles safer. The flashiest was BMW’s self-riding motorbike, which was able to steer itself around the convention center’s lot without falling over. We also saw how autonomy will affect the trucking and logistics industries. Freightliner showed off a Level 2 semiautonomous trailer cab that brings many of the modern advanced driver aid features from passenger cars to semi trucks. 0 CES 2019 2020 BMW M340i review: A dash of M makes everything better Tags 2:25 Post a comment 2020 Kia Telluride review: Kia’s new SUV has big style and bigger value The concepts of tomorrow Forward-looking CES had no shortage of interesting concept cars, a few of which we’ve already seen before. Mercedes-Benz’s Vision Urbanetic concept made its North American debut on the Las Vegas Strip. Roadshow was there to take it for a spin — or rather, be taken for a spin in this autonomous car. Uber talked quite a bit about its plans for flying taxis at its Elevate conference series in 2018. CES 2019 gave many their first in-person look at what to expect from that with the Bell Nexus flying taxi concept. It looks a bit like a big ol’ drone with seating for four passengers and a pilot and it could be taking to the air for test flights in early 2020. I’ve saved the “Where we’re going, we don’t need roads” reference for perhaps the weirdest concept at the show. Hyundai’s Elevate concept is an electric emergency response vehicle with legs between its body and wheels. Able to transition between driving and walking modes, it’s a crazy future ambulance that can scramble over rocky terrain like some kind of lizard car.

TVs of CES: Huge 8K screens and insane roll-up OLEDs. 10 life-changing things I learned at CES 2019 At a smaller scale, startup Udelv debuted its second-generation autonomous delivery truck. The Udelv Newton has a longer range and is more flexible than the Udelv’s previous truck and will be hitting the road this year as part of pilot delivery programs with Walmart in Arizona and XL Parts in Texas. And that’s just scratching the surface. There’s so much more to discover in our coverage of CES 2019 and more to come as we wrap up our coverage of the big show and roll straight into the Detroit Auto Show next week. BMW’s riderless, self-driving motorcycle goes for a spin… 56 Photos Though many come for the insane TV tech, smart appliances and cute robots, CES 2019 is also the first major car show of the year. Transportation and mobility steals a little bit more of the show every year with more vehicle debuts, more crazy concepts and more tech finding its way into the cars. To bring you up to speed, here’s a quick roundup of the best automotive news we’ve seen here in Las Vegas. New vehicle debuts CES saw the debut of the long-awaited, long-range version of Nissan’s Leaf EV. The 2019 Leaf E+ tweaks the world’s best-selling electric car formula with a larger battery pack that bumps its range to about 226 miles, a significant boost over the current model. Meanwhile, Mercedes-Benz debuted its coupe-y, swoopy 2020 CLA-Class in Las Vegas this week. The compact sedan is packed with style, but bursting at the seams with tech, including Benz’s MBUX connected infotainment system and a healthy dose of driver aid technologies. (A bit of a power bump over the A-Class doesn’t hurt, either.) Byton Electric car startup Byton only debuted part of the production version of its M-Byte electric SUV, but it’s arguably the most exciting and contentious part. The M-Byte production cockpit features a massive 48-inch screen — that’s as large as seven iPads — and a touchscreen in the center of the steering wheel. We expect to see the rest of the car later this year.

COPY LINKAD Loading … In an unexpected turn of events, Microsoft and Sony announced on Thursday that they will be working collaboratively for the development of cloud services and more. The two tech giants have come together after a gruelling 10-year old rivalry to develop the future. This not only marks the beginning of an unexpected (but secretly wished for) venture but also proves that when needed, even fierce rivals are willing to come together and collaborate for a better tomorrow.The partnershipAs per their agreement, “the two companies will explore joint development of future cloud solutions in Microsoft Azure to support their respective games and content-streaming services.” Thus, it is expected that Microsoft Azure will play a key role in the partnership.Kenichiro Yoshida, the president and CEO of Sony said, “For many years, Microsoft has been a key business partner for us, though of course, the two companies have also been competing in some areas. I believe that our joint development of future cloud solutions will contribute greatly to the advancement of interactive content.”He also mentioned the collaboration of the two companies in the areas of semiconductors and AI, hopeful that a new value for society will be created by “leveraging each company’s cutting-edge technology in a mutually complementary way.” This announcement comes barely a month away from the world’s biggest gaming conference, E3. Kenichiro Yoshida, President and CEO, Sony Corporation (left), and Satya Nadella, CEO, MicrosoftMicrosoftOf course, here rises the question of the level of advancement the new alliance can bring into the world. We have seen some spectacular technology being developed by both companies over the years. Microsoft has been developing innovative consumer-level products for the world, including the mixed-reality-based HoloLens.Sony gave us the PlayStation VR, which enabled users to experience a whole new level of immersion. Their upcoming console is also touted to have top-of-the-line specs with an SSD for cutting loading times, ray-tracing abilities and 3D audio support.Microsoft did not get daunted by these announcements, promising that the upcoming Xbox will be more powerful than Sony’s console. This spat between the giants is another reason to think about possible ulterior motives behind this partnership.What does this mean for consumers?It is tempting to think about the future of this partnership: Has the age-old rivalry really ended? Will we be able to see cross-platform gaming across all titles?We have seen how Microsoft has been trying to change the way games are played. ‘Play Anywhere’ allows certain Xbox games to be played on the PC by cloud-saving the save states. Sony came into the industry earlier with PlayStation Now, but they lack the infrastructure that Microsoft has been developing. Both these services are distinct, yet with this new collaboration, it seems possible that the two companies can consider bringing more than just cross-platform play into the picture. Microsoft – Sony join handsReutersMicrosoft’s CEO, Satya Nadella said, “Sony has always been a leader in both entertainment and technology, and the collaboration we announced today builds on this history of innovation.”However, it isn’t advisable to jump to conclusions. Kyle Orland from Ars Technica believes that this may be a ‘keep your enemies closer’ scenario where both companies have their own interests at heart – Sony wants to use Microsoft’s advanced cloud technology, while Microsoft wants to squeeze that creative juice out of their new allies.Theorising aside, we can break down facts about the industry’s plans. Google has announced its own streaming service, Stadia, which seemed a very exciting technology during the demos. Moreover, reports suggest that Amazon may be developing its own cloud-based streaming service to add to the competition. This strengthens the possibility of obsolescence of gaming consoles by replacing them with streaming boxes.Is this the endgame for consoles?Gaming consoles may not become obsolete, because, for one, both Microsoft and Sony are hard at work with their new consoles (which already have been confirmed to have high-end CPUs and GPUs). At the same time, we have reason to believe that consoles meant specifically for gaming may be replaced by consoles which specialise in streaming, changing the way people game altogether. The logo of Sony Corp’s PlayStation is seen next to a woman at its booth during the Tokyo Game Show 2014 in Makuhari, east of Tokyo September 18, 2014.REUTERS/Yuya ShinoStreaming consoles are probably going to be a big thing, with Microsoft already having announced one console without support for physical media. If you’re wondering what the difference would be, these consoles will have high-end network cards and high RAM capacity to support the game as they stream the environment.It would be nice to see connectivity to multiple screens over a wireless network, but that is just wishful thinking. It is highly likely that companies will offer some sort of subscription for the gaming service, which will also be tiered according to genre or publisher.That change, however, is a thing of a future that is pretty far away. Most existing gamers would prefer having a quality, seamless experience of a dedicated gaming device that streaming a video of a game simply cannot replicate. The prospect of playing Forza and The Last of Us on a cheap streaming box or phone seems enticing, yet impure. Sure, freedom to game is important, but playing The Witcher 3 on a 6-inch phone will undoubtedly take away from the experience.Choppy frames, input lag and low-resolution streaming can be major problems for the next generation. However, as is the thing with technology, these problems will soon be overcome as newer infrastructure rolls in. With mixed reality, cloud gaming, and the ever-improving infrastructure, there may be a day when all games will be available for any screen at any time at low-priced subscriptions.This alliance creates tension for some in the community and opens exciting prospects for others. Developers and consumers alike can look forward to technology that will be more accessible than ever and allow for even greater levels of immersion.

Journal information: Physical Review E (Phys.org)—A small team of researchers with École Polytechnique in France has found that all trees, regardless of size or species, tend to break at near the same wind speed. In their paper published in Physical Review Letters, the team describes tests they conducted in a lab and how they came up with a scaling law to describe the point at which a tree will break due to wind stress. Trees employ similar strategies to outcompete their neighbors © 2016 Phys.org People have noticed for some time that when high winds strike, trees, regardless of size, age or species all seem to snap in a given area—but only when the wind reaches some given speed. Up until now, it has not been clear if all trees snap at the same wind speed, or if there is a gradient of sorts. To find out, the researchers in France conducted experiments where they attached water buckets to wooden rods to measure both their flexibility and the point at which they would break. In so doing, the team found that the rods tended to break at near the same point. Next, the team combined their lab experiments with data collected by others over time that suggested that trees tend to snap when wind speeds reach approximately 42 meters per second. Using all the information at hand, the team came up with a scaling law to describe when a tree will break due to wind force: (V∼D0.75/L), where V is wind velocity, D is diameter of the wood and L is its length. When applied to trees, rather than just rods, the team found that variance due to physical differences between species was minimal—doubling the size of the tree, for example, made a difference of just 9 percent, and oak trees, notorious for their strength broke at speeds just 10 percent higher than pine.The researchers explain that the size of a tree does not play a bigger role because they grow at a rate where their height is proportional to diameter, and because the larger a tree grows the more defects in the wood come into play—also as a tree grows larger, more and more of its surface area is exposed to wind forces.

DOI: 10.1103/PhysRevE.93.023001ABSTRACTData from storms suggest that the critical wind speed at which trees break is constant (≃42m/s), regardless of tree characteristics. We question the physical origin of this observation both experimentally and theoretically. By combining Hooke’s law, Griffith’s criterion, and tree allometry, we show that the critical wind speed indeed hardly depends on the height, diameter, and elastic properties of trees.

Darjeeling: A portion of an under-construction flyover came crashing down at Phansidewa in Darjeeling district on Saturday without injuring anybody, police said.The incident happened near Kanthibhita in Phansidewa town along the National Highway 31D.Four laning of the highway is presently going on in the stretch which is a part of the East-West corridor envisaged under National Highways Development Project — Phase II, and is a vital link for connectivity to the North-East. Also Read – Rain batters Kolkata, cripples normal lifeSDO, Siraj Daneswar, BDO and DM Jayashi Dasgupta were present along with the police team at the spot since early morning.”This is an accident caused by some technical fault. The technical staff and the engineers on the project can give a proper explanantion for the same. The investigation has begun and the construction procedure has been stopped unless the matter is investigated by the National Highway Authority of India(NHAI),” said Dasgupta, the District Magistrate.Though 25 meters of the under-constructed flyover has collapsed, there are no reports of any injury. The area had been cordoned off by the police later in the morning.
