Many bleeding-edge trends in the consumer web play out writ large in financial markets; as all of us look at the growing prominence of real-time information on the web, the debate over flash stock trading raises issues worth considering outside the stock markets as well. If the real time web at large grows up open and democratic, then we’re likely to see innovation, understanding and growth. If it’s priced out of reach to all but marketing and state interests, then an experience analogous to that of small-time stock traders today could become what the web at large looks like.It’s easy for technologists to say that this is progress and rejecting the advantages technology brings would demand a return to time before the abacus. It’s not so easy to explain why we have to take an all-or-nothing approach to judging technologies and their implications – why not look at them one at a time and evaluate them intelligently? Here’s how the introduction of real time information is being debated regarding financial markets, followed by some thoughts about the analogous transformation going on around the web.This isn’t just a story about robot stock traders and the SEC; it’s also a story about Twitter, Facebook and the Pushbutton Web.Robots in Financial MarketsLast month the New York Times’ Charles Duhigg wrote a high-profile story about the practice of high frequency trading, including this juicy description of the practice:Powerful algorithms — “algos,” in industry parlance — execute millions of orders a second and scan dozens of public and private marketplaces simultaneously. They can spot trends before other investors can blink, changing orders and strategies within milliseconds.High-frequency traders often confound other investors by issuing and then canceling orders almost simultaneously. Loopholes in market rules give high-speed investors an early glance at how others are trading. And their computers can essentially bully slower investors into giving up profits — and then disappear before anyone even knows they were there.Rich Miller, writing at Data Center Knowledge, a blog that tracks the powerful computers that high frequency traders (among many other industries) use, called the article one-sided and inconsiderate of the argument that “this activity provides liquidity to execute trades that would otherwise not be possible, making the market more efficient.” He also said the press was widening the debate over the practice by bringing it into the mainstream.Now U.S. Senator Charles E. Schumer (D-NY) has sent a letter to the SEC this week, calling for action to be taken against the practice of flash trading in particular, the act of selling for a fee access to trading information milliseconds before it is otherwise available. He argues that the practice “creates a two-tiered system where a privileged group of insiders receives preferential treatment, depriving others of a fair price for their transactions. If allowed to continue, these practices will undermine the confidence of ordinary investors, and drive them away from our capital markets.”Schumer focuses on the early access to information, but always in the context of the computer-driven trading that occurs based on it.Trader John Hempton writes that critics over-estimate the financial impact of flash traded stock, needlessly complicating a situation that he describes with the following, fascinating, story:We trade electronically at our fund. We were recently trading in a stock with a large spread. I have changed the numbers so as not to identify the stock – but the ratios are about right. The bid was about 129.50, offer was about 131.50. We did not want to cross the spread – so when we bid for the stock we bid $129.55. Within a second a computer (possibly at our own broker but it makes no difference which broker) bid $129.60 for a few hundred shares. We fiddled for a while changing our bid and watching the bot change theirs. We would have loved to think we were frustrating the computer – but alas it was just a machine – and we were people up late at night.Actually obtaining the stock required that we paid up – and when we did so it was probably a computer that sold the stock to us.…It is always there – even when buying defaulted debt that trades once per month. We simply ALWAYS find the bot. What About Real-time Robots on the Web?Could the real time web give some people such an unfair advantage over everyone else that non-early adopters of new technologies or people outside of marketing firms could be left out in the cold? Presuming we’re talking about important, actionable information online and not just real-time chat and fun – it’s possible. The question is: will the most important parts of the real time web be open and democratized, or proprietary and shared only with those who can pay a high price for access? That question hasn’t been answered yet.If you were among the people who purchased the new Breaking News Online (BNO) iPhone app (released an eternity ago, yesterday!) then today you probably found out about the two US journalists being freed from North Korea and the shooting in Pennsylvania at least 45 minutes before almost anyone else did. (CNN posted a link to local PA news 45 minutes after the BNO network published.) That notification system costs $1.99 to purchase and $1 per month to stay subscribed.If you’ve visited Yahoo’s social-bookmarking turned real-time news service Delicious since this morning, you’ve seen that hot news links are now found not just by vote counting, but with a new method augmented by tracking the open, rapid conversations on Twitter.These are innovations built out of elbow grease and publicly available feeds of data. Yahoo might be, but the scrappy guys at Breaking News Online definitely aren’t, using software something like IBM’s new stream processing software, for which it will charge “at least” hundreds of thousands of dollars.No, this real-time public web is very low cost and increasingly both open sourced and decentralized. It’s akin to what Anil Dash calls the pushbutton web.Pushbutton is a name for what I believe will be an upgrade for the web, where any site or application can deliver realtime messages to a web-scale audience, using free and open technologies at low cost and without relying on any single company like Twitter or Facebook. The pieces of this platform have just come together to enable a whole set of new features and applications that would have been nearly impossible for an average web developer to build in the past.As long as it’s open and low cost, real time information on the web should be as democratic and fair as computer use is. It’s not perfect, but it’s no longer the David and Goliath-on-steroids fight that critics of high frequency stock trading say that market has become because of real time stock data.The Risk: FacebookThe real time web is a shimmering mass of conversation and data, but there’s no guarantee that it’s going to stay open, free and democratic forever. Already, in fact, there’s no bigger river of the real time social web than Facebook. Facebook is simply huge, it holds huge sums of information and so far it allows aggregate access to no one. As far as we know. If Facebook, or some other equally important site of the real time web, began offering access to its data but pricing mere mortals out of that market – then we could have a situation where individual software developers and social scientists were like grandpa reading the stock pages in the newspaper and huge marketing firms and government agencies had the kind of advantage that high frequency traders are alleged to have in financial markets.Anil Dash puts it this way:Pushbutton technologies are not just free and open, they’re decentralized, which is a serious threat to the “lobster trap” model of social software. We can expect serious competition from the centralized networks that are currently building these sorts of systems. If a threat arises to Pushbutton’s adoption, this is the most likely source. Worry? Definitely.In addition to development concerns, there are also analysis concerns. If stock trading equals liquidity and knowledge is the new currency, then open access to aggregate data could be the equivalent of high-powered stock-trading tools for all instead of for just the already-richest few.Some research has already been performed on the connection between communication on social networks and real-world events. The Information and Language Processing Systems Informatics Institute at the University of Amsterdam, for example, correlated mood messages on LiveJournal closely with world events. (“Mass increase in the level of worriedness around major weather phenomena, such as hurricane Katrina on August 29, 2005 – Excitedness around global media and culture events, such as the release of a new Harry Potter book on July 15, 2005 – Mass increase in the level of distress and sadness after terror attacks, as witnessed by the response to the London bombings on July 7, 2005.”)Analysis of real time mass communication could lead to a world of innovation and understanding – if that communication is an open fire hose of data and not shared only with deep pocketed commercial partners.Everything is Complicated, Some Can Afford to Ponder ItIs high frequency, low latency, computer executed, “flash” trading unfair? It must feel that way to individual and small investors who can’t afford killer number-crunching robots – but it’s also pretty awesome technology and is said to provide liquidity that the markets depend on.Could the real time consumer web be made undemocratic by being priced out of reach for edge-case developers and social scientists outside of government and the corporate world? That could happen. As we speak, though, there’s a lot of innovation going on in the real time web that’s open, based on standards and available to all of us. Let’s hope it stays that way marshall kirkpatrick
Facebook is Becoming Less Personal and More Pro… A Comprehensive Guide to a Content Audit Related Posts Tags:#Facebook#web Guide to Performing Bulk Email Verification Last night, we reported that Facebook was planning to release a JIT compiler for PHP, a huge step toward making the PHP runtime – and PHP-based sites and apps – faster by taking the interpreted lagnuage (a.k.a., more human-readable code) a few steps closer to the bare-metal ones and zeros machines actually read.We’ve been updated this morning that the PHP runtime has in fact been rewritten, with an extra step: The PHP is translated to C++ (a more machine-readable language) which is then compiled with g++. This project, called HipHop, has been in development under great secrecy at Facebook for the past couple years and has just this morning been open sourced.Facebook engineer Haiping Zhao writes, “With HipHop we’ve reduced the CPU usage on our Web servers on average by about fifty percent, depending on the page. Less CPU means fewer servers, which means less overhead.”We’re sure this is good news for Facebook’s brand new data center, still under construction.“HipHop executes the source code in a semantically equivalent manner,” Zhao continues, “and sacrifices some rarely used features – such as eval() – in exchange for improved performance.”He also notes that while interpreted languages such as PHP, Ruby and Python – the languages that, by and large, rule the web of apps and social site we all use today – allow for huge strides in developer productivity, they are also less efficient and often simply slower in runtime. For a huge and ever-growing site such as Facebook, this might have eventually led to scalability issues.In other words, it cost Facebook less to create a faster PHP runtime than to buy all the servers that would be needed to support hundreds of millions of users without a faster runtime.“Scaling Facebook is particularly challenging because almost every page view is a logged-in user with a customized experience,” writes Zhao. “When you view your home page we need to look up all of your friends, query their most relevant updates (from a custom service we’ve built called Multifeed), filter the results based on your privacy settings, then fill out the stories with comments, photos, likes, and all the rich data that people love about Facebook. All of this in just under a second. “HipHop allows us to correct the logic that does the final page assembly in PHP and iterate it quickly while relying on custom back-end services in C++, Erlang, Java or Python to service the News Feed, search, Chat and other core parts of the site.”Zhao notes that PHP and C++ share relatively similar syntax, although C++ is by far less taxing on system resources. While it would have been impossible to write the codebase by hand, Zhao had been tinkering with programmatically converting PHP to C++ for a few years. He got the idea at a Facebook Hackathon, he said.UPDATE: Late last night, we pinged PHP creator Rasmus Lerdorf on Twitter, asking for his opinions on the rumored PHP compiler. This morning, he wrote, “I think HipHop is cool and will certainly help the poor people stuck in framework soup.” However, he also noted, “HipHop on simpler template-style PHP pages probably isn’t going to help you too much. It’s not going to make your SQL queries any faster.”We will update this post as news continues to break. The Dos and Don’ts of Brand Awareness Videos jolie odell
Police have arrested two persons on the charge of beating a one-and-a-half-year-old child to death in a fight that followed an objection by the infant’s father to a child from the accused family urinating in the open at Bagaspur village in Sagar district of Madhya Pradesh on October 1. The accused have been identified as Ram Singh and his son Umesh.“As a six-year-old boy was urinating on the road, the child’s father objected to it. And in turn, the boy’s father and grandfather attacked attacked him with lathis. The 18-month-old boy he was holding suffered blows and died on the spot,” Amit Sanghi, Sagar Superintendent of Police, told The Hindu.“There is a running feud between the two tribal families,” he said.A case was registered under Section 302 [punishment for murder] of the Indian Penal Code. The injured father is being treated at a local hospital.The case had no similarities to the Shivpuri case where two children were beaten to death for allegedly defecating in public, Mr. Sanghi stated, adding, “There is confusion. There is no case of open defecation here.”
The Australian Sports Awards were a night of glitz and glamour, with representatives from the Australian Mens 30’s Touch side holding down a table at the Sydney event last night…if you were up late enough watching the SBS broadcast you would have even seen Tony El Takchi’s television interview in the introduction.Nominated in the Masters Team of the Year Award, the side rubbed shoulders with other award nominees, including Grant Hackett, Liesel Jones, the Sydney Swans and more.Unfortunately for the side, they were beaten for the award by the Australian Mens 55’s athletics relay team, although the recognition of making the final three for the award is still something special.Keep an eye on the website for a full report of the evening from the team, coming soon.

JaVale McGee has gone a long way toward shedding the persona he got from “Shaqtin’ a Fool,” the TV blooper segment on which he held residency for years. Coming off consecutive NBA titles with Golden State, the 7-footer is currently logging career highs in points and blocks per game with the Lakers while serving as a full-time starter for the first time since 2011-12. Not bad considering the collective confusion when he agreed to a deal to join LeBron James in Los Angeles.But for all the improvement he’s shown as a mainstay in this lineup, the 30-year-old still has an Achilles’ heel when it comes to his defense: McGee remains the league’s supreme goaltender.As of Wednesday, McGee had been called for goaltending an NBA-high 13 times, nearly twice as many as Orlando rookie Mo Bamba, who ranks second in the league with seven violations. The Knicks, who also have 13 goaltending violations, are the only team that’s been called as many times as McGee himself, according to PBP Stats, which tracks a wide array of advanced NBA statistics. But this is nothing new for McGee: Since his rookie year, he has somehow managed to lead the NBA in goaltending violations per 100 possessions in each of the eight seasons in which he logged at least 400 minutes of playing time.With 214 goaltends in his career,1This includes 11 in the postseason. including one season when he logged a league-high 55, there have obviously been some true head-scratchers. One violation in 2012 was particularly egregious: The ball was in clear, undeniable descent before McGee launched it, volleyball-style, into the stands 25 or so feet in the air.Puzzling as they might be from time to time for his coaches, the goaltending calls probably aren’t that big of a deal. Getting called for something that costs his club 2 points — 2 points they might have surrendered anyway — is arguably small potatoes compared with the upside of blocking a shot. And that’s likely even more true of McGee, who this year has blocked 5.3 shots for every goaltending violation.But McGee’s willingness to lunge at nearly every shot attempt the way a cat flails at a laser pointer can cost his team in other ways. His block attempts often hurt the Laker defense more than if he had simply stayed on the ground. Take a late October game against the Spurs, when McGee committed three shooting fouls — resulting in seven San Antonio free throw attempts in a 1-point defeat — that stemmed from him ramming into jump-shooters. Twice, LaMarcus Aldridge pump-faked McGee into the air, knowing his constant tendency to go for blocks. (DeMar DeRozan did the same thing to McGee when the Lakers visited San Antonio.) Over the past two seasons, McGee has posted the second-highest foul rate when it comes to big men bumping into jump-shooters, according to data from Second Spectrum.2Among those with at least 10 such fouls. Only Portland’s Zach Collins has a higher foul rate in such scenarios.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2018/12/JaVale1.mp400:0000:0000:55Use Up/Down Arrow keys to increase or decrease volume.While McGee may not have the greatest on-court instincts, the reason he attempts to block so many shots is simple: He thinks he’s capable of cleanly blocking them all. He’s highly athletic — remember the dunk contest in which he jammed on two side-by-side rims at the same time? — and at one point McGee owned the largest wingspan in the entire league, at more than 7-foot-6.“That’s something [the referees are] not used to seeing,” McGee said of a particularly ridiculous block, when he caught the ball with one hand — and appeared to do so cleanly — but was whistled for goaltending anyway.“I think he tries to be spectacular,” then-Nuggets coach George Karl said in 2013 when asked about McGee’s game. “Basketball is a game of possession after possession of doing things the right way, doing your job and letting the spectacular come. I think JaVale tries to find the spectacular and forces the spectacular when if … you just let us orchestrate the game, something big-time will happen.”Another prolific rim protector, Tyson Chandler, sized up McGee’s game nearly eight years ago in a post from a Wizards blog. Chandler presciently said the then-Wizards center needed “to understand how he can be effective,” and that he would learn that by playing with more established veterans. McGee gained that experience with Golden State — and now Chandler is backing up McGee with the Lakers.McGee has been a force this season. He’s been a top-10 rim protector3Among players who’ve logged at least 15 games and who have defended five shots or more from inside of 6 feet per game. so far, holding opponents more than 10 points beneath their averages from inside of 6 feet, according to NBA Advanced Stats. In large part because of their play at center, the Lakers rank fifth in the league in opponent field-goal percentage inside 3 feet and ninth in overall defensive efficiency. And while there were once questions about McGee’s basic fundamentals, those concerns have largely evaporated. Just look at last year’s NBA Finals, when McGee played incredibly solid defense after being switched onto LeBron.What will be worth watching on Thursday, when the Lakers play foul-drawing maestro James Harden and the Rockets, and this postseason4If Los Angeles makes it. is whether McGee can avoid being baited by fakes. If savvy teams like the Spurs already know to test his ability to stay on the ground, it’s almost a given that other teams will try it in a series.In a way, the key to the Lakers rising to become true contenders could very well be based on McGee’s ability to stay grounded on defense.Check out our latest NBA predictions.
After another 100-yard rushing performance, sophomore running back Carlos Hyde has proven that he should be the undisputed No. 2 running back for the Ohio State offense. I’m not someone who enjoys controversy or likes to stir it up, but in my mind, there should be no controversy. The numbers speak for themselves. With just eight more carries than junior running back Jordan Hall, Hyde has compiled 183 more yards with a team-high of 513. Hyde also has four more touchdowns than junior running back Jordan Hall. How can the coaches argue with that production? One common argument for Hall is his “big play ability.” Hall’s biggest play against Wisconsin, the last game in which he played, was a fumbled punt return that gave Wisconsin momentum and a chance to get back in the game. Maybe that is a little cynical, as he did score a touchdown in the third quarter and his final kickoff return gave the Buckeyes great field position to retake the lead for the eventual victory. However, Hall’s touchdown was from two yards out. With three inches of height and 43 more pounds packed on his frame than Hall, I would be willing to bet that Hyde could have punched it in just as easily. Also worth noting is that Hall’s longest rush of the year is 20 yards, compared to Hyde’s long of 63 yards. Is Hall really a bigger play threat than Hyde? Hyde voiced his displeasure with his spotty playing time after the Buckeyes’ victory against Illinois on Oct. 15 on Twitter saying, “Guess I’m not good enough. Take myself elsewhere.” He later (wisely) deleted the tweet and said he wasn’t going anywhere. The damage had been done, though, and his displeasure is evident. But can you blame him? Hyde is only a sophomore and would be in the Buckeye backfield for another two years. Hall, a junior, only has one more year at OSU. If Hyde were to become disgruntled and transfer elsewhere, the Buckeyes would be missing out on at least one, if not two years, of solid backfield play from the runner. Senior running back Daniel ‘Boom’ Herron voiced similar confidence in Hyde following the victory against Indiana. “(Hyde’s) got a great future ahead of him. It was really nice to see him do a great job,” Herron said. “It was great to see him take advantage of the opportunities given to him today.” Keywords: “great future” and “opportunities given to him today.” Coach Luke Fickell and the coaching staff would be wise to keep Hyde as involved in the game plan as possible this week and throughout the season to prepare for the future, as well as get the greater production. With Hall coming off of an ankle injury, Fickell said at his Tuesday press conference that “hopefully (Hall) will be able to go” but “he’ll be a little bit hesitant.” He also said that Hall will retake his position as punt and kickoff returner while the coaches find a way to move the ball around and give all the running backs opportunities to touch the football. I guarantee that given an opportunity to touch the football, Hyde will not be hesitant to take it to the Purdue defense. Put him in, coach.
