Gareth Barry: Record-breaker, great Premier League survivor

first_imgMOST READ Kammuri turning to super typhoon less likely but possible — Pagasa Fire hits houses in Mandaluyong City Read Next Don’t miss out on the latest news and information. Chooks’ Austin won’t back down in possible clash vs Blatche in Champions Cup That’s still not the case for Barry. Only last year, he was being hailed as “one of the best English players ever” by his then-coach at Everton, Roberto Martinez, who is admittedly prone to hyperbole, after a man-of-the-match performance against Man City in the League Cup semifinals.He was a much-cherished member of City’s Premier League title-winning team in 2011-12, shoring up the midfield to allow Yaya Toure to rampage forward. He had turned down a move to Liverpool to join City.Barry has slotted seamlessly into his new surroundings at West Brom, where he has replaced another veteran midfielder in Darren Fletcher.“They’re bastions of this sport,” West Brom manager Tony Pulis said. “The young players at our football club, I hope they realize how lucky they are to see someone of that quality and that ilk.”Barry has worn the captain’s armband for England on several occasions among his 53 caps for his country. Globally, however, the most vivid image of Barry in an England jersey was in 2010 when he trailed in the wake of Mesut Ozil in the build-up to Germany’s final goal in its 4-1 win in the round of 16 at the World Cup.Outside of the Premier League era that started in 1992, goalkeeper Peter Shilton holds the appearance record for England’s top flight with 849 games. Former Chelsea defender/midfielder John Hollins has made more outfield appearances in the top flight than any other player, with 714. “It’s a huge number when you think about it,” Barry said ahead of his potentially record-breaking game. “It’s gone so quickly.”Barry played 365 league games for Villa, 132 league games for Manchester City, 131 league games for Everton and has featured in four league games for West Brom.Having started out as a center back equally comfortable at left back, he is now an out-and-out holding midfielder—perhaps the best position on a soccer field for someone his age, as it involves a player using his head as much as his legs.Barry credits his longevity to avoiding serious injury and to support from some now-retired former teammates.“No one has said, ‘What are you doing still playing?’” the 36-year-old Barry said. “Everyone said, ‘Play as long as possible.’ You stop when you stop enjoying it and I’ll know when I’ve had enough and can’t keep up with the boys.”ADVERTISEMENT LATEST STORIES Frontrow holds fun run to raise funds for young cancer patients Brace for potentially devastating typhoon approaching PH – NDRRMC Nonong Araneta re-elected as PFF president In this Saturday, Sept. 16, 2017 photo, West Bromwich Albion’s Gareth Barry gestures, during the English Premier League soccer match against West Ham United, at The Hawthorns, in West Bromwich.

Of his current tally of 632, he has started 600 of them. It is a testament to Barry’s longevity, adaptability and quality that he has lasted so long in the fast-paced, blood-and-thunder world of English soccer.

Taapsee wants to learn pole dancing from Jacqueline

first_imgMumbai: Actor Taapsee Pannu says she wants to learn pole dancing from her Judwaa 2 co-star Jacqueline Fernandez. She said this on a talk show recently. Asked what would she do if Jacqueline was her neighbour, Taapsee said: “I think we’ll be working out together, she works out really crazy. I don’t mind learning pole dancing from her. I know I’ll be horrible at it but I really want to work out with her,” she added. The actor wants to be filmmaker Anurag Kashyap’s best friend. “I want to be his best friend and tag along to fancy Hollywood parties. It is my ultimate desire to attend Hollywood parties,” she said. Taapsee worked with Kashyap in Manmarziyaan and is working with him again in a supernatural thriller. At the moment, Taapsee is busy with Saand Ki Aankh, which also features Bhumi Pednekar. It is based on old sharpshooters – Chandro Tomar and her sister-in-law Prakashi Tomar. Chandro, 87, and Prakashi, 82, are from Uttar Pradesh’s Johri village and reportedly took up sharpshooting in their 50s. Chandro, fondly called shooter ‘dadi’, is among the world’s oldest female sharpshooters. Directed by Tushar Hiranandani, Saand Ki Aankh also features Prakash Jha and Vicky Kadian in pivotal roles.last_img read more

My Experience with Twitter So Far

first_imgPeople who put up five, six, 10tweets in a few minutes, all with links to the event they’re at, or worse, totheir promotional stuff, are annoying. I probably couldn’t say what exactlyTwitter is supposed to do, but I can tell you, from my perspective, that’s notit. In December I signed up for Twitter. I’dbeen meaning to do it for a while, but hadn’t, because a) I’m not really anearly adopter and b) I wasn’t sure where another social network fit into myschedule, which already has Facebook,Flickr and mediaPRO. But I believe in Rex Hammock’s philosophy of experimenting innew forms of media, so it had been on my list of things I needed to do. AndI get all the potential value, from both the marketing and journalisticperspectives, among others. The catalyst was a lunch I had withMichael Biggerstaff and Marcus Grimm at NxtbookMedia. They were really into Twitter at the time, and said it was a quickerform of communication than blogging, and that you’re more likely to updatebecause the “tweets” have to be quick hits. Twitter does a spotty jobtechnically. Every few days, a bunch of people report they lost all the tweetsthey posted that day. The noise level is out ofcontrol. It’s not a conversation, it’s a cacophony. It’s like a cocktail partyfrom hell, where everyone is shouting at the same time, and someone also jackedup Led Zeppelin in the other room. If social media is aconversation, it’s barely there on Twitter. People overwhelmingly tweet at eachother. Apparently, conversation is rarely needed or desired. Twitter is,ironically, a one-way communication vehicle in a medium that is supposed to besocial. So I signed up and built a network. Some of the people I follow are reallygood. Dan McCarthy (@danielmccarthy), Jeff Klein (@jeffreysklein), Kurt Andersen(@kbandersen), who does a great job of adding personal but business-relevanttouches), Rachel Sklar (@rachelsklar), and Rex (@r) himself come to mind. So do Ted Bahr (@tedbahr), Eric Gervase(@egervase) and Red 7’s own Loree Stark (@loreestark). Harry McCracken (@harrymccracken),Scott Karp (@scottkarp) and Dylan Stableford (@stableford) are good. Gawker(@gawker) does a great job.FOLIO: (twitter.com/foliomag) and AudienceDevelopment (twitter.com/auddevmag) both signed up recently. Someone asked me last week why ITwitter, and why FOLIO: and Audience Development Twitter, and I said I thoughtthe value was thought leadership, not traffic. If you build a network ofinfluential people, and put out brief and thoughtful tweets (not always linkingto something), there’s real value. I have just under 100 followers and Ifollow about the same amount of people. And here’s the way I feel about Twitterright now: Twitter does a poor jobcontrolling spamming and bogus accounts. If you’re active at all, you get hitwith “follow” requests that are spurious, completely unrelated, sketchy, andyou have to check out the profile to tell what the hell they are. All thesecomplaints aside, I check Twitter several times a day and tweet every day, andas I mentioned, some of the people in my network really get it and bringinsight, perspective and inspiration.last_img read more

Facebooks in the midst of an identity crisis and the Portal is

first_img CNET Smart Home CNET Smart Home See All Do we really care though?Perhaps most interestingly, this hasn’t stopped people from buying Portals — or Amazon smart speakers. CNET’s own Rick Broida isn’t bothered by Facebook’s privacy stuff:I’ll just say I’m fully aware that every company on the planet is already collecting and sharing data about me in order to try to sell me stuff. And for the most part I’m not bothered by it. That’s just me.Well, maybe not just me: The Portal has a 4.6-star average rating from over 400 Best Buy customers and a 4.4 average from over 300 Amazon customers. Seems as though people really like the product, Facebook issues notwithstanding.Another colleague, Ian Sherr, feels differently: Why can’t you [Facebook] fix all this stuff before trying to sell us a device that, at best, already faces an uphill battle in trying to convince people that putting yet another internet-connected doorway into their homes is a good idea?(Gut check: Am I the only one who thinks Facebook’s Portal is the wrong product at the wrong time? Michael Pachter, an analyst at Wedbush Securities, said Portal is “downright creepy” and wanted to ask, “How much pain are you willing to go through to see it succeed?”)Some people will always care more about privacy than others. And that’s all fine and good. But I can’t imagine anyone thinking the Portal and the Portal Plus were well-timed product releases in light of Facebook’s ongoing issues or that we’d all just line up and buy a bunch of these things. Mark Zuckerberg’s social network is in the midst of a serious identity crisis. “Hey Portal, flash your screen once if you need help.” Aug 31 • The best coffee grinders you can buy right now Facebook’s pricey Portal Plus brings loved ones closer • The Facebook Portal gets a huge price cut: $99 Facebook Portal is an excellent video chat device held back by Facebook’s trust problems Related links Aug 31 • Alexa can tell you if someone breaks into your house Now playing: Watch this: Share your voice 3:05 4 Aug 31 • Best smart light bulbs for 2019 (plus switches, light strips, accessories and more) Portal, interruptedThe Portal idea is sound in theory: Buy a Portal for yourself and give a friend or family member far away another Portal. Make dinner in your apartment while you video chat with your parents across the country. You can move around naturally within the Portal’s field of view, pulling cheese, milk and butter from the fridge. (We’re apparently making mac and cheese in this made-up scenario… and now I’m hungry.) You’re fishing for the stock pot in that hard-to-reach spot in the lower cabinet across the kitchen and grabbing pasta from the pantry — all within your parents’ view as you catch them up on your week. The Facebook Portal is a video-chatting system first and foremost. Admittedly, and perhaps annoyingly, Portal does this job really well. It also offers a limited dose of smart home functionality via a built-in Amazon Alexa speaker, select apps including Newsy, Pandora and Spotify (Premium only) and Facebook’s own “Hey Portal” voice assistant. Note: Facebook has temporarily dropped the price of the Portal to $99 and is offering it bundled with the Portal Plus for $200 off through May 12, just in time for Mother’s Day, all while reports of privacy breaches continue to trickle in. And other news surfaced this week that Facebook is working on new AI tech for the Portal, Oculus and other upcoming, as yet unannounced Facebook products. Could Facebook be working on a rival to Amazon Alexa and Google Assistant in addition to its existing “Hey Portal” assistant?A spokesperson told me over email that Facebook hasn’t announced a new voice assistant, but rather that they “are working to develop voice and AI assistant technologies that may work across our family of AR/VR products including Portal, Oculus and future products.” Hm. facebook-portal-messenger-chat-2204Enlarge ImageThe Facebook Portal looks a lot like the Amazon Echo Show. It only works over Facebook Messenger, so you — and the people you want to chat with — have to have Facebook to use it. James Martin/CNET Portal privacy and youAnticipating our reticence to the Portal, Facebook detailed its smart display privacy policy on this support page. While Facebook says it doesn’t listen in on or “keep the contents” of your Portal chats, a spokesperson told us that Facebook does gather info about the calls you make to determine what ads to show. It won’t listen in on the calls, but it will log the length and other data. The company shared more details in an email to Recode: “Portal voice calling is built on the Messenger infrastructure, so when you make a video call on Portal, we collect the same types of information (i.e. usage data such as length of calls, frequency of calls) that we collect on other Messenger-enabled devices. We may use this information to inform the ads we show you across our platforms. Other general usage data, such as aggregate usage of apps, etc., may also feed into the information that we use to serve ads,” the Facebook spokesperson said. I wonder if Facebook execs ever discussed temporarily or permanently shelving Portal so its person-tracking camera didn’t launch during the same time people were deactivating their accounts in outrage? But the company instead went for the “Hey, it’s cool. You can totally trust us” vibe. That approach demonstrates a shocking level of tone deafness. (Again, I’ll refer you to this story outlining many of Facebook’s major privacy leaks and other serious issues the company’s faced lately.)Facebook isn’t the only media company scaring the crap out of us, though. Amazon employs, you know, human people, to listen to your Alexa recordings. Creepy doesn’t even come close to cutting it.

James Martin/CNET Like many folks, I felt uneasy about the Facebook Portal from the jump.Having been an only intermittent Facebook user over the past several years made me an even less willing participant when it came time to test the smart display and the company’s pricier Portal Plus last fall. Did I have a Facebook account? Yes, technically. But it was as good as inactive save the odd toggle-share from Instagram that I rarely checked. Despite Instagram’s propensity toward over-curated fakery (#blessed) and the fact that it’s a Facebook company (irony abounds), it’s still largely considered the “good side” of social media. It’s the place guaranteed to have adorable puppies, drool-worthy food and far-flung travel destinations when you need a break from the more serious side of the internet. Facebook has a different reputation. It’s the underbelly of the ol’ world wide web, complete with awkward familial spats over political convictions, cryptic messages from college sweethearts and, worst of all — multiple, privacy-threatening data leaks. So it was surprising when Facebook announced the camera-equipped, Facebook-Messenger-dependent Portal ($199) and Portal Plus ($349) in 2018, amid regular breaking news stories about how Facebook misused user information and then tried to downplay it to the loyalists remaining on the platform once it was uncovered. What’s more, Portal cameras aren’t like most smart display cameras. They have particularly smart tech that differentiates between people and houseplants and can therefore follow you around a room — not exactly the device you want from a company cited for its privacy problems. reading • Facebook’s privacy crisis makes its Portal video device a tougher sell than ever Facebook’s video calling smart display connects you with friends and familylast_img read more

Photo: Moinul IslamThe extramarital affair of Rangpur public prosecutor (PP) Rathish Chandra Bhoumik’s wife was the reason behind his murder.Rapid Action Battalion (RAB) director general Benazir Ahmed said this at a press briefing at RAB-13 Headquarters in Rangpur on Wednesday.Rathish’s wife Snigdha Sarker confessed to RAB that she had an extramarital affair with her colleague Kamrul Islam and they planned to murder Rathish two months ago.Both Snigdha and Kamrul are teachers of Tajhaat High School of Rangpur.Rathish was killed on Thursday night. He was first made unconscious as 10 sedative pills were mixed with his food. They then strangled him to death, Benazir said quoting Snigdha’s confessional statement.The body was then left at the basement of an under-construction building in Mollahat area of Tajhaat with the help of two youths.On Snigdha’s confession, RAB members recovered the body around 2:30am Wednesday, in a drive that started at 8:30pm on Tuesday. The PP’s brother Sushanta Bhoumik identified the body of Rathish. Four including Snigdha and Kamrul have been so far arrested in this connection.Rathish, 55, who represented the state in a case over the killings of Japanese national Hoshi Kunio and Rahmat Ali, khadem (caretaker) of a shrine, went missing on Friday morning.Read More:Missing Rangpur PP found deadlast_img read more

Texas Gambling Rules Explained You Can Play Bingo Or The Lottery But

first_imgBy Todd WisemanHey, Texplainer: Why do I have to go to other states to gamble?When Texans want to spin a roulette wheel, pull the arm of a slot machine or try their hand at scooping up the pot in the center of a poker table, many pack their bags and head for Louisiana, Oklahoma or Las Vegas. That’s because in most cases, it’s illegal in the state to gamble.For the past several decades, Texas legislators have largely frowned on the idea of relaxing the state’s gambling laws out of concern for morals and negative social effects. But Texas’ gambling laws aren’t by any means the strictest in the nation, and there are some forms of legal gambling that do take place.Texans may buy lottery tickets or place bets on horse races and greyhound dog races. The state’s also more lax on “social gambling,” or gambling that takes place in private places. Bingo games or charity auctions are usually allowed, so long as the organizer doesn’t take any portion of the profit.But what about casinos?Some of the three federally recognized Native American tribes in the state can own and run casinos on their lands. Right now, there are two casinos operating on reservations located near Livingston and Eagle Pass.The Kickapoo Lucky Eagle Casino near Eagle Pass is a fully functioning casino, complete with a poker room and gaming machines. It’s as close as Texans can get to Las Vegas-style casinos without leaving the state.Meanwhile, Naskila Gaming, a casino-like facility near Livingston, is the focus of an ongoing legal battle between the state and the Alabama-Coushatta Tribe. Texas Attorney General Ken Paxton says the facility is subject to state laws. The tribe says it has federal authority to allow certain kinds of gambling. Right now, the venue is operating, but the state is trying to shut it down. There are also new forms of gambling-oriented businesses popping up throughout the state, such as the Post Oak Poker Club in Houston. Texas law maintains that an “organizer” can’t take money from the pot in games of chance. Instead, the poker club charges patrons a series of rental fees.Poker clubs like the one in Houston are in a legal gray zone, according to Greg Gladden, a lawyer who practices gambling law in Houston. He said the gaming laws aren’t clearly written and are enforced in different ways throughout the state. Gaming laws could changeFor years there has been a debate over whether the state should expand, clarify or get rid of its gaming laws.Some Texas legislators, such as state Rep. Carol Alvarado, D-Houston, say it’s time to leave some gaming laws up to the voters. She filed a bill in 2011 with the intent to do just that.“I know some of my colleagues get heartburn about allowing Texans to decide,” Alvarado said. “But Texans like to gamble, and if we do it smart, we could create economic development in the state.”Letting voters decide might lead to destination casino gambling – or casinos like those in Louisiana that have hotels – being legalized, she said. In 2011, a University of Texas/Texas Tribune poll found 56 percent of Texans supported allowing full casino gambling in the state. Alvarado said she thinks a law that allows for destination-type casinos would cut down on the amount of illegal gambling and could help generate additional revenue. She said she’ll file a similar bill in the next legislative session.“I’m going to continue to propose it until we pass it,” Alvarado said.Meanwhile, the U.S. Supreme Court could rule as soon as Tuesday on whether individual states should have the right to decide whether they want to allow gambling on sports. Right now, legal sports gambling is essentially confined to Nevada. But even if the Supreme Court opens the option to other states, Texas might not jump at the chance to legalize the practice. In 2015, Gov. Greg Abbott, a Republican, told the Texas Lottery Commission that he “wholeheartedly” supports the current state restrictions on gambling. The bottom line: Texas gambling laws are complex, but Texans don’t necessarily have to leave the state in order to gamble. Sharelast_img read more

Researchers build two versions of new most accurate clock ever

first_img © 2013 Phys.org Explore further (A) Laser light at 578 nm is pre-stabilized to an isolated, high-finesse optical cavity using Pound-Drever-Hall detection and employing electronic feedback to an acousto-optic modulator (AOM) and laser piezoelectric-transducer. This stable laser light is then delivered to the Yb-1 and Yb-2 systems, where it is aligned along the optical lattice axis to probe the atomic clock transition. Resonance with the atomic transition is detected by observing atomic fluorescence collected onto a photomultiplier tube (PMT). The fluorescence signal is digitized and processed by a microcontroller unit (MCU), which computes a correction frequency, f1;2(t). This correction frequency is applied to the relevant AOM by way of a direct digital synthesizer (DDS), and locks the laser frequency onto resonance with the clock transition. (B) Relevant Yb atomic energy levels and transitions, including laser cooling transitions (399 and 556 nm), the clock transition (578 nm), and the optical pumping transition used for excited state detection (1388 nm).

They describe their new clock in a paper they’ve uploaded to the preprint server arXiv. In it they suggest that if their clock could somehow be used to gauge the age of the universe, it would be able to do so within just a single second. More information: An atomic clock with $10^{-18}$ instability, arXiv:1305.5869 [physics.atom-ph] arxiv.org/abs/1305.5869AbstractAtomic clocks have been transformational in science and technology, leading to innovations such as global positioning, advanced communications, and tests of fundamental constant variation. Next-generation optical atomic clocks can extend the capability of these timekeepers, where researchers have long aspired toward measurement precision at 1 part in $bm{10^{18}}$. This milestone will enable a second revolution of new timing applications such as relativistic geodesy, enhanced Earth- and space-based navigation and telescopy, and new tests on physics beyond the Standard Model. Here, we describe the development and operation of two optical lattice clocks, both utilizing spin-polarized, ultracold atomic ytterbium. A measurement comparing these systems demonstrates an unprecedented atomic clock instability of $bm{1.6times 10^{-18}}$ after only $bm{7}$ hours of averaging.via Arxiv Blogcenter_img Journal information: arXiv As time has passed, clock-making has become more important—besides helping people get together at prearranged times, clocks now help run the GPS system, keep networks on track and are key to unlocking the fundamental laws of the universe. As technology has grown in sophistication, so too has the need for ever more accurate clocks. This has led to atomic clocks which use the electronic transition frequency in the ultraviolet, optical or microwave region of the electromagnetic spectrum to keep very accurate time. In this new effort, the researchers built a new type of atomic clock that is more accurate than any that has come before.To build their clock the researchers employed a laser and mirrors to build a lattice trap capable of capturing atoms—its purpose was to hold atoms steady so that there wouldn’t be any frequency interference, a problem with other atomic clocks. The trap was then filled with ytterbium atoms which were then shot with a second laser to measure their electronic frequencies. The result was a clock that if allowed, would be off by less than a second if run for 31 billion years.Building a clock that is believed to be the most accurate in the world creates a problem though, how to accurately measure its accuracy? The answer is by building another clock exactly like the first of course and then comparing the two against one another. That’s what the researchers did, running both clocks for a short period to see if they came up with exactly the same time duration, which the researchers report, they did.One of the first uses for the new clock will be in measuring gravitational redshift, which is a means of measuring very precisely, the height of geographic areas. This can be done because time moves slower in areas of higher gravity. The researchers say their new clock is capable of measuring redshit to within 1 centimeter.
