Did Zebras Invent Their Own Stripes?

first_imgThe explanations some evolutionists give for fur and feather patterns sound like tales of talking animals planning out their new fashion lines.Evolution tries to explain not just what is, but how it got that way.  The core of Darwin’s theory is that stuff happens by unguided natural processes – no mind or planning was involved.  Things may look designed, leading evolutionists tell us, but that’s an illusion: they evolved.  Apparent designs are the outcome of processes that did not have them in mind – namely, random mutations and natural “selection” for accidental traits that might confer a survival advantage.  Yet reporters and scientists who believe this often write as if animals determined ahead of time what they would do to get more fit, have more sex, or avoid predators.  A case in point is the origin of patterning on mammals and birds.MammalsZebra-cadabra:  The stripes on zebras are remarkable for their starkness and symmetry, with some stripes going horizontal and some vertical.  Such bold markings do not blend into the background to provide camouflage.  Why would they announce to predators “Here I am”?  Are they for social communication?  Then why are both males and females and young all striped?  At long last, the BBC News was proud to announce that the mystery of the stripes has finally been ‘explained’ (quotes theirs), at least for the satisfaction of “evolutionary biologists.”  The new theory is: “Zebras’ bold stripes protect the animals by masking their movements.”   All those moving stripes create an optical illusion when predators or biting insects approach.One of the researchers compared the stripes to the barber-pole illusion or the wagon-wheel illusion (when the spokes appear to turn backward).  The problem with those analogies is that we know barber poles and wagon wheels are intelligently designed.  Darwinism needs to account for zebra stripes by undirected, mindless processes.  Dr. Martin How fails to tell how:According to Dr How, zebra stripes capitalise on this type of illusion to help protect the animals.He explained that the broad diagonal stripes on a zebra’s flank and the narrower vertical stripes on its back and neck give unexpected motion signals that confuse viewers, particularly in a herd of zebras.“We suggest that these illusions cause pests and predators to mistake the zebra’s movement direction, causing biting insects to abort their landing manoeuvres and chasing predators to mistime their attacks,” said Dr How.Sounds convincing, but any explanation needs to face follow-up questions.  If striping is such a successful strategy, why didn’t wildebeest and antelope evolve it?  Why aren’t all members of the horse family striped, when they presumably also have to deal with predators and biting insects?  Does it also explain the stripes on zebrafish, zebra mussels and striped skunks?  How did the first stripes on zebras originate by mutation?  How did the stripes become so regularly spaced and uniform over the entire body?  Were the selection pressures so strong in the case of the mutant with the first tentative stripes, that all the unstriped members of the population died out?  Did the mutation for stripes have any pleiotropic effects that reduced fitness?  Will this explanation fare any better than last year’s attempt to hypothesize that the stripes repel biting flies? (2/09/12).  Doesn’t an explanation about how the stripes work actually imply design?  Doesn’t Dr. How’s wording suggest that the stripes are the designer, if they “capitalise” on an illusion?  How is this not a fallacy of personification?We are informed that this explanation was quite a feat, a long time in coming: “Zebra stripes have long confused evolutionary biologists, right back to Darwin and Wallace,” one of the researchers said.  The illusion, therefore, appears to work very well on evolutionists.BirdsPatterns of a feather flock together:  A photograph of a handsome California quail, adorned in its multi-colored costume of feathers, some with bold edges overlapping like roof shingles, others plain gray, all fitting into their own specific areas on the bird, topped with a feathery tuft over the fashionable head, adorns a Science Article that announces to readers it will explain the “evolution of plumage patterns in male and female birds.”  Some matter-of-fact stuff about taxonomy and sexual dimorphism precedes the evolutionary explanation.  Then we learn that evolutionists have largely ignored the question of feather patterns: “The colour of plumage has attracted much research interest, but the exquisite patterns of bird plumage, such as the spots of the guinea fowl and the barred patterns of ducks and turkeys, to just name a few, have received much less attention,” said a PhD candidate at Cambridge out to make her name in the Darwinian storytelling society.  First, it was necessary for Thanh-Lan Gluckman to eliminate the unfit:“It was argued that male birds developed their spectacular colours and elaborate patterning as a result of their mating patterns — they used their plumage to compete for and attract females. On the other hand, female birds needed to blend into their surroundings in order to nest safely and protect their young — so they became drab and dull to protect themselves and their young from predators,” said Gluckman.What this implies is that evolutionists have been wrong for 150 years.  It certainly seems so, if they were attributing purpose to birds that are supposed to be evolving without planning.  In a search for forces that would produce patterning, Gluckman studied 288 species of waterfowl and gamebirds, and found “a fabulous number of variations and combinations of these visual patterns in females as well as males.”  She couldn’t see any rhyme or reason to the evolutionary trends for monogamous or polygamous species.  It didn’t appear that sexual selection could explain all cases of sexual dimorphism (the contrast in appearance between males and females).  What’s going on?“By emphasising similarities as well as differences in plumage patterns between male and female birds, rather than whether one sex is the same as the other, I found that sexual dimorphism in the plumage pattern of birds is highly nuanced and that there can be multiple types of sexual dimorphism. In expanding the definition of sexual dimorphism, and reconstructing evolutionary history, I found that changes in sexual dimorphism could be due to changes in males and/or females. In addition, the plumage patterns of birds seem to transition easily between different types of dimorphism, which is congruent with adaptation to fluctuating social and environmental conditions,” said Gluckman.The evolutionary pattern in patterning is there is no pattern.  Changes “could be” due to “males and/or females.”  It’s all “highly nuanced” and seems to “transition easily.”  In one sense, this is an improvement over evolutionary explanations that suggest birds planned their evolution.  In another sense, it makes things worse for evolutionists.  Sexual selection appears to have no explanatory power.  Stuff happens, Gluckman appears to say, in no predictable way.  But when all is said and done, evolutionists still don’t know how those quail became so handsomely adorned.Has there ever been a more useless theory that claimed such great things for itself than Darwin’s theory of evolution?  Here we are, 154 years after the Origin launched a revolution in thinking that helped motivate two world wars and a takeover of academia, and they have nothing substantial to say.  When it comes to details, they are still clueless why zebras are striped and why quail are so beautifully patterned.  Instead, we get a steady stream of “could be” and “perhaps” but nothing definitive that ties the theory to the observation in a robust way.  When they try, usually they first have to overturn the previous evolutionary explanation.It’s one thing to classify and observe.  Scientists are good at that.  It’s nice to know the distribution of stripes on zebras, and even how they function as an optical illusion.  It’s good to know how many species of waterfowl and gamebirds there are, which ones exhibit sexual dimorphism and which ones don’t.  Any “citizen scientist” can do as much.  But when it comes to explaining how things got the way they are, evolutionists provide no value added.  Saying “stuff happens” is no help at all.Because “apparent design” is so widespread in the living world, evolutionists stoop to violating their own rules.  They word their explanations with design language: such-and-such “evolved to” perform a function.  We must call them out when they commit this contradiction.  It is an “illegal procedure” foul, given the processes of neo-Darwinism, to say that zebra stripes “evolved to” create optical illusions, or quail feathers “evolved to” adapt to changing environments or diverge males from females (except when they don’t).  Remember, evolution is blind, acting on random variations.  Inside a cell nucleus, it’s dark.  A pre-zebra has no idea that a cosmic ray hit one of its sperm, the one that (by chance) was destined to fertilize an egg that would make an embryo develop a stripe on its right hind leg.  A lion has no idea that this stripe is supposed to confuse it so it eats the plain zebra ancestor.  Whoops; the lion ate the one with the stripe, or the alligator got it.  Start over and wait another million years.This crazy theory masquerades as a scientific explanation but adds nothing – zilch – to our understanding.  We’re tired of the just-so stories.  One thing creationists and evolutionists could unite on is biomimetics (12/16/13).  No religion required, no evolutionary storytelling required – just a recognition that there are designs in nature we could learn from.  Both sides agree things look designed.  So, let’s study those designs together (whether you think they are apparent or real) and turn them into products that could help everybody.  This can get science out of the explanatory morass Darwin led us into, and move science forward.

South Africans on top of the world

first_img3 June 2005Sibusiso Vilane has reached the summit of Everest for the second time, this time the 8 848m peak from the more difficult North Ridge. He was part of a team that included fellow South African Alex Harris.The summit was reached at 7.20am (local time) on Friday. The climbers, part of an expedition by British outfit Jagged Globe, spent a little more than an hour on the summit before beginning their descent.Another South African, Anthony van Marken, summitted with the Alpine Ascents team the previous day.Two years ago Vilane made history, becoming the first black African to reach the peak of the world’s highest mountain. He is now the first black African to have summitted Everest twice from different approaches.This was Harris’ third attempt on the mountain the locals call Chomolongma. He was the leader of the ill-fated Discovery Everest expedition that was forced by the weather to turn back when only 350m from the summit in 2003.With this ascent, Harris becomes only the second South African to have climbed the Seven Summits – the highest mountain on each of the seven continents – after Sean Wisedale.Wisedale was a member of Harris’ 2003 Discovery expedition, and was able to summit then after joining another team.When Sibusiso Vilane reached the summit of Mount Everest in 2003, he said he “felt as though I was stepping onto a very sacred place … I fell to my knees weeping”. (Photo copyright 2003 Discovery Everest Expedition)Vilane, who has dual South African and Swaziland nationalities, was climbing in part to raise funds for three charities, the Birth to Twenty Research Programme at Wits University, the Africa Foundation and the SOS Children’s Village in Swaziland.The Birth to Twenty Research Programme is an initiative run by the university which examines socio-economic, socio-political, demographic and nutrition transitions taking place in South Africa, according to Wits marketing’s Shirona Hassim.Speaking before leaving on the expedition in March, Vilane said he wanted to concentrate on his professional speaking when he returned from Everest.“I would love to get involved with schools around the country, to motivate and inspire the youth to believe in their dreams and make them a reality”, he said.SouthAfrica.info reporterlast_img read more

Junior Boks through to JWC semis

first_imgFinishing strongly, the Baby Boks dominated the last 10 minutes of the contest and Kolbe signed off with a mesmerising run to cross untouched for a try. “We played much better towards the end, especially during the last 10 minutes. I am just relieved that we managed to beat them because they are a dangerous team. We will now regroup and prepare for the semi-final.” Far from beatenFrance, however, were far from beaten and they struck back when eighthman Marco Tauleigne went over in the corner. The French then took the lead with a converted try from Baptiste Serin. 14 June 2013 “We knew that the French would be passionate and very committed because they had so much to play for. They were lifted by a fantastic crowd and gave it their all,” coach Theron said after the match. Down 19-18, South Africa hit the front once more six minutes after that when Pollard slotted another penalty. Reflecting on the match, South African captain Ruan Steenkamp commented: “They disrupted us from the start and forced us into mistakes. We could not get the momentum that we wanted, but we showed a lot of bravery and heart out there. Shortly afterwards, for the first time in the tournament, however, South Africa trailed in a game when an intercepted pass led to Thibault Regard going over for France. A successful conversion put the hosts ahead. Four-time winners New Zealand qualified as the top seed and were also joined in the final four by Wales and England, who claimed the final place as the best of the runners-up, just ahead of Ireland and Argentina. Seeded secondThe win left the defending champions undefeated after their pool games and seeded second for the semi-finals, based on their pool points and points’ difference.center_img After England, a team South African later beat, defeated the French 30-6 in their first pool match, some might have expected an easier contest for coach Dawie Theron’s charges, but it was far from that as the home team produced a tigerish display in front of their own supporters. South Africa will take on Wales in the semi-finals, with New Zealand up against Six Nations champions’ England. In the 14th minute, the first of four Handre Pollard penalties (he landed four of six in the game) then put the South Africans back in the lead by a single point. The score was the same at half-time time, 8-7 in favour of the green and gold. ‘Proud’“However, I am proud of the effort by each of my players because the win is what mattered most, and we deserved it in the end. Our guys stood firm, made some vital tackles and in the end we clinched it with a great try by Cheslin Kolbe.” The South African under-20 team secured a place in the semi-finals of the IRB Junior World Championship after a hard-fought 26-19 victory over hosts France in a Pool A match played at at Stade Henri Desgrange in La Roche-sur-Yon on Thursday evening. Early in the second half, Cheslin Kolbe, one of the stars of the championship with his mazy, elusive runs from fullback, set up Luther Odi to score in the corner and a Pollard conversion made it 15-7. Three minutes later he added a penalty to put the champions 18-7 clear. Began with a bangThursday’s evening match began with a bang for the Baby Boks when centre Dries Swanepoel sliced throught the French defence to open the scoring in the first minute.

Protection sought for South Africa’s sardines

first_img8 June 2015Scientists are trying to prove that the sardines that appear on the KwaZulu-Natal coastline are a different population group in the hope of pressuring the government to give them better protection.There is a belief that time is running out, with research revealing that with each passing season the annual sardine run is becoming less predictable.It is unclear why, but over-fishing of the commodity before it reaches the KwaZulu- Natal coastline is believed to be a contributing factor.Last week, a pilot shoal landed in Margate, but recent rough seas may have dashed any hope of another shoal being spotted any time soon.The shoal moves up the East Coast generally when water temperatures drop during winter, beginning its trek at the Agulhus banks, south-east of Port Elizabeth. The main batch heads up the West Coast while a smaller group, just 2% to 5% of the entire South African population, goes to KwaZulu-Natal.KwaZulu-Natal Sharks Board operations head Mike Anderson-Reade admitted another poor season could be problematic following the lacklustre season of the last two years.Fewer sardines“Last year was the first time I did not handle a sardine in my career. If we have three bad cycles then we possibly have a reason to be concerned.“It is important. It is nature’s bounty. Very little is for free yet these fish provide good protein. It is a special event,” said Anderson-Reade.Dr Allan Connell, a South African Institute of Aquatic Biodiversity honorary research associate who has been collecting sardine eggs for 25 years at Park Rynie on the South Coast, said his data had revealed that the last 12 years had been less “predictable than the first 12 years”.Connell takes samples weekly, sometimes daily, which includes 226 separate species of eggs and early larvae of fishes spawning pelagic eggs.“The first half of my data in relation to sardines was stable and predictable, the second half not so.”Study of ear boneConnell said the researchers were trying to prove that sardines spawned on the KwaZulu-Natal coast returned every year for their approximate five-year life cycle. To do this they were peering into the otolith (ear bone) for their study. The study is currently focused on juveniles of about 10mm to 15 mm, with larger sardines expected to be part of a later study. “Our first study has shown that the chemistry of the otolith is different in the Natal Sardine to the West Coast Sardine.”He said they were waiting to complete two more studies. “One batch in research is not conclusive enough to convince statisticians. But because the sardine runs have been wobbly, the chances are less that we will find juveniles.”He said if their research was conclusive and proved that the KwaZulu-Natal sardine was a different population from that of the West Coast sardine, it could be used to tighten fishing controls.“Without the science it will be difficult to convince the politicians of the need to better manage the sardines.”Justin Mackrory, the chief executive of South Coast Tourism, said the annual sardine run, nicknamed ‘The Greatest Shoal on Earth’, helped to contribute to the about R500-million economic injection into the region during winter.The Department of Agriculture, Forestry and Fisheries was approached for comment but was unable to provide a response at the time of going to press.Source: News24Wirelast_img read more

Lokpal bill: Govt harassing me, says Anna Hazare

first_imgA day after the civil society members of the Lokpal panel lashed out at the government for trying to kill the anti-corruption bill, Anna Hazare said he was being harassed by the government. He says the government is raising unnecessary issues regarding his Hind Swaraj Trust. A team from the charity commissioner’s office had visited Ralegan Siddhi on June 6. It had obtained a few records from the trust for inspection. The government team also recorded statements of the trustees in connection with allegations of financial irregularities. Hazare says the charity commissioner’s office was charging his trust with financial irregularities, only to harass him.  The anti-corruption activist, who is leading a campaign against the government, has dared the authorities to file a case against his trust. “We have submitted all papers to the charity commissioner office. If we are at fault, let them file a case against us. We are ready to fight the case, because we are clean,” said Hazare.  At a public Lokpal debate, conducted by Headlines Today on Thursday, Hazare said while the government was making all sorts of allegations against his team instead of engaging in a constructive discussion on the Lokpal bill, his trust was also not spared. However, the investigating agencies would not be able to find anything, because he had “no bank balance”, Hazare said.For more news on India, click here.For more news on Business, click here.For more news on Movies, click here.For more news on Sports, click here.last_img read more

AN ADDRESS TO THE NATION ON NATIONAL HERITAGE DAY

first_img National Heritage Month Events featured in all islands Facebook Twitter Google+LinkedInPinterestWhatsApp Facebook Twitter Google+LinkedInPinterestWhatsAppProvidenciales, 08 Oct 2014 – Culture is the soul of a nation; the finest expression of humanity and a record of a people’s evolution and advancement. From Salt Ponds, to the Conch Farm; from “going-in-the-field” to billion dollars luxury resorts; from the peaceful donkeys in Grand Turk to the Private Jets in Providenciales; from potato bread to Lobster in reduction sauce; Pepper Joy to Bambara Rum, as a people our cultural story demonstrates a culture in evolution and advancement and that my fellow countrymen is our Heritage. This is what has and will distinguish us from every other nation in the world. It is our unique marker, our signature across history and it is what follows us into the world even as it brings the world to us. And so, I call on you, as your Queen, with pride and affection for all that we are throughout our National Heritage Month, on October 13th; National Heritage Day and beyond, to embrace it. Let me tell you why our heritage means so much to me, and why in this wide, vast world, as we let our imaginations soar across our borders; we must keep our minds rooted firmly in our own historical truth:There are many ways to enter what is beautiful about us, what is humane and what gives us grace, but for me it is the music. We seem to breathe and live by a certain rhythm and melody. I feel it when I do not hear it. But as soon as I hear that Rake n’ Scrape, I feel like a bundle of smiles, and I see the humour, the practicality, the simplicity and the sense of dignity that is in our national character. You see, Rake n’ Scrape to me means a people who have little, but are content to make beauty even with the little they possess. There is something magical, warm and honourable about that. That is our heritage.Who can fail to see and feel something special about our people? We are all Sister and Brother. At every turn we are Cousin… “cuz” so and so. Speaking to us about family is like speaking about the elements of chemistry: we say: “She is my grandmother’s aunt’s husband’s second daughter, but she is my third cousin”. We are “Titter” this and “Babba” that. It is charming and funny, but underneath it reflects and confirms a tradition of respect amongst us, amongst generations of brothers and sisters that is dying in other places around the world. And yet, when the world comes to our shores, we welcome then into this culture of family. This too is our heritage.I love the land, our land – Beautiful by Nature, (Bountiful by Skill), as God intended and the angels obliged. And while I love the fresh mornings, or the Sweet Salinas at Salt Cay, the old world charm and gentility of Grand Turk, and as I am seduced by ambition by Provo’s luxurious race into the future, and made tender by North Caicos’ tending of the soil or Middle Caicos’ calm, where time seems still, and of course, the historical “swag’ of the “Big South”, it is the Flamingoes for me: They seem ancient and delicate. I love the fact that their colour comes from the interaction between what they eat and what the sea provides… because the sea is how we survived. This is also our blessed heritage.In some countries they have monuments and we have our little share. But ours is a remembered culture and a heritage to be acknowledged, remembered and celebrated. I am your honoured Queen and unlike other Queens, I am empowered by you only to issue decrees of love. Let us love what we are through what we have been as the path to what we must become. Let us live with the grace of our national story… and let us gain from and give to our heritage all that gives love, and so gives life to life.Shanice WilliamsMiss Universe Turks and Caicos 2014 Recommended for you Related Items:miss tci universe, national heritage month, shanice williams National Heritage Month ends New TCI based magazine debuts: Karibelast_img read more

2019 TV buying advice Get a 2018 TV now or wait for

first_img iTunes app, AirPlay 2 Far-field mic for hands-free voice 8.3 No idea Quantum dots, more dimming zones 8.2 Far-field mic for hands-free voice The best TVs of CES 2019 Vizio P-Series Best new feature Vizio P-Series Quantum I’m guessing LG’s 2019 OLED TVs, coming soon, won’t perform significantly better than the 2018 versions seen here. Sarah Tew/CNET The last big TV sale event of the season, the Super Bowl, is now behind us, and ahead lie a bunch of brand-new 2019 models to tempt shoppers. Late winter and early spring are when most of the new TVs hit store shelves and online, and some are even available now. If you want a new TV now, perhaps one thought is “I shouldn’t buy an obsolete 2018 TV now when new ones are just around the corner.” Allow me to add a complexifier or two. A 2018 TV bought today is not obsolete. TVs are a mature technology and most will do everything you need for years to come. The improvements on many 2019 TVs will be minor compared to 2018 models available now. For most of this year, you’ll pay more for a 2019 TV than you will for the roughly equivalent 2018 model. The earliest you can expect 2019 TV prices to fall to 2018 levels is mid-November 2019. If you’re OK waiting until November and Black Friday season to buy your 2019 TV, then by all means do so. You’ll probably get the best deal on a new TV.  7.0 2 Now playing: Watch this: TVs 13:20 None Brighter, more dimming zones, 75-inch size available 2019 TV comparisons No Yes 8.6 2018 CNET rating Sony X900F But if you want a new TV now and missed your opportunity to snag something in the last few months on-sale, you face a conundrum. Will the 2019 version coming soon be a better choice than 2018 version you can buy now? I can’t actually answer that question for sure until I review the new TVs and compare them directly to the older ones. But in my years of doing just that as a TV reviewer at CNET, I’m willing to take some educated guesses now. No Samsung Q8 Comments Processing Viewing angles, processing No Vizio M-Series Quantum Tags Processing Samsung Q9 Quantum dots, more dimming zones Yes Yes LG OLEDB8P AirPlay 2, HomeKit Sony X950G Viewing angles, processing Samsung Q80R iTunes app, AirPlay 2 Vizio E-Series The best TVs at CES 2019 Vizio V-Series Katz’s guess: Significantly better picture? 6.9 No 7.7 2019 TV series 8.7 Vizio M-Series AirPlay 2, HomeKit Built-in Alexa AirPlay 2, HomeKit 2018 TV series 8.0 7.5 None No Yes 8.1 Armed with the information from the chart above, you can get some idea of what the TVs of 2019 will bring to the table compared to their predecessors, and hopefully make a more informed decision. And if you’re looking for more info on 2019 TVs, here the latest I have on 2019 TVs from LG, Samsung, Sony, Vizio, TCL and Hisense. Some stuff to keep in mind: Again, these are just guesses based on manufacturer info and my past experience testing TVs. I haven’t seen any of the 2019 TVs in person beyond brief glances at CES, let alone subjected any to a full CNET review with measurements, side-by-side comparisons and the whole bit. I say “significantly better” because even those TVs that get a “No” could show slight improvements. For example, improved processing on the C8 last year did produce a somewhat better picture than the B8 in my tests, but it was so minor that I still chose the less-expensive B8 as CNET’s Editors’ Choice for high-end TVs. Just because I’m guessing a 2019 TV will have a better picture doesn’t mean the 2018 version isn’t worth buying. I’m guessing the successor to the TCL 6 series (whatever they end up calling it) will be a better performer for example, but the 6 series is still an excellent choice and remains CNET’s Editors’ Choice for now. Speaking of TCL, it’s the only maker on the chart above that hasn’t specified model numbers for most of its 2019 TVs. Hence the “TBD” and “No idea.”Unless you’re rich, no 2019 8K TV is worth waiting for. Unless you’re a hardcore gamer or a Dolby Atmos user who needs eARC, no 2019 4K TV with HDMI 2.1 features is worth waiting for. A handful of new 2019 TVs lack immediate predecessors I reviewed, yet could still be excellent choices for some buyers this year. They include the Samsung Q70R (the cheapest Samsung with full-array local dimming, or FALD), the Hisense R8 (an inexpensive Roku TV with FALD) and of course LG’s rollable OLED. The bottom line? All of this advice will evolve as I review new 2019 TVs, the 2018 models start selling out and the 2019 TVs fall in price. As always, waiting until later in the year will help you make a more informed decision. But if you can’t wait, here are the best TVs to buy right now. 8.7 Vizio P-Series Quantum X LG OLEDC8P TCL 5 TCL S405/S305 TBD AirPlay 2, HomeKit Samsung Q90R Yes 61 Photos 8.1 LG OLEDB9 TCL S425/S325 Far-field mic for hands-free voice TBD Brighter Vizio P-Series Quantum Quantum dots, more dimming zones None TCL 6 No Share your voice Picture quality improvements Built-in Alexa TBD 2018 vs. 2019 TVs compared: Buy now or wait Here are all of the TVs CNET reviewed in 2018 (with overall ratings) and all of their nearest 2019 successors.

Your Mac could be hijacked through major security flaw in Zoom conferencing

first_img 14 Photos Now playing: Watch this: The top 3 upgrades in MacOS Catalina 0 4:39 Apple Aug 31 • iPhone XR vs. iPhone 8 Plus: Which iPhone should you buy? In a statement, Zoom said the local web server is a workaround for Apple’s Safari 12 web browser, introduced last September.”Zoom installs a local web server on Mac devices running the Zoom client,” the statement reads. “This is a workaround to an architecture change introduced in Safari 12 that requires a user to accept launching Zoom before every meeting. The local web server automatically accepts the peripheral access on behalf of the user to avoid this extra click before joining a meeting. We feel that this is a legitimate solution to a poor user experience, enabling our users to have seamless, one-click-to-join meetings, which is our key product differentiator.”In regard to a potential denial of service attack, Zoom says it has no record of such a weakness being exploited, and says it fixed that security flaw in May. Along with the likes of Slack, Uber and Pinterest, Zoom is one of many tech companies to go public in 2019. It raised $356 million upon its April 18 IPO, with its shares trading as high as $66 on that day. The stock has risen since, currently sitting at around $90.70.

Sarah Tew/CNET Your computer’s webcam has always been a gateway for potential security intrusion, which is why people like Mark Zuckerberg and ex-FBI head James Comey put tape over theirs. On Monday, security researcher Jonathan Leitschuh gave Mac users another reason to fret over their webcams — there’s a security flaw in the Zoom video-conferencing app.Zoom is most notable for its click-to-join feature, through which clicking on a browser link takes you directly to a video meeting in Zoom’s app. But Leitschuh in a Medium post explained that he months ago discovered Zoom achieves this in insecure ways, allowing websites to join you to a call as well as activating your webcam without your permission.He added that this would allow any webpage to denial-of-service a Mac by repeatedly joining you to an invalid call. Uninstalling the Zoom app from your Mac isn’t enough to fix the problem, either. Zoom achieves its click-to-join function by installing a web server on your computer — which can reinstall Zoom without your permission.”If you’ve ever installed the Zoom client and then uninstalled it, you still have a localhost web server on your machine that will happily re-install the Zoom client for you,” Leitschuh writes, “without requiring any user interaction on your behalf besides visiting a webpage.

After Harleen Sethi is Vicky Kaushal dating Malavika Mohanan

first_imgInstagramVicky Kaushal’s onscreen performances have generated the same kind of buzz that his off-screen life has. The interest around one of the country’s most eligible bachelors refuses to die down and rightly so! Well, ladies, brace yourselves as this particular piece of information might be very hard to digest.After breaking up with Harleen Sethi, Vicky Kaushal is allegedly seeing actress Malavika Mohanan. It has barely been a few months since Vicky Kaushal made news for his relationship with actress Harleen Sethi and then made subsequent news for their unceremonious break-up and now, the Uri actor is back in news for dating Ishaan Khatter’s Beyond The Clouds co-star – Malavika Mohanan.A pinkvilla report states, “Malavika is always talking glowingly about him to everybody. She likes him so much she cannot stop gushing about him and while Vicky is more reticent, he does these little romantic gestures, like dropping in and surprising her on the sets of one of her South films and taking her out for lunch. Vicky loves home-cooked South Indian food and often drops in on the Mohanan house in Mumbai like Thursday night. Even though he’s a Punjabi, he loves the South Indian style fish-curry and rice but on Thursday he was disappointed it was not there so Malavika pulled his leg on Insta by posting “Deprived of fish curry and rice. Life is not a Mani Ratnam film today.”Prior to this, Vicky Kaushal was also in news for his alleged closeness to Katrina Kaif and Bhumi Pednekar. Bhumi was cited as the reason for his breakup with Harleen Sethi. Needless to say, Malavika and Vicky look fabulous together and we hope this time, Vicky comes out in the open and accepts his relationship.last_img read more
