Vegas has weighed in on Big 12 expansion with fairly predictable results. The four biggest favorites to enter the Big 12 are BYU, Houston, Cincinnati and Central Florida. I’m pretty sure everyone thinks BYU, Houston and Cincy are the three big dogs when it comes to Big 12 expansion. The question seems to be not “if?” but “when?” and “how many?”Oddsmakers are apparently now handicapping Big 12 expansion. Here are your current odds from Sports Betting Dime.— Kellis Robinett (@KellisRobinett) August 9, 2016Some have suggested the league could be expanded by four to 14 teams. Going from 10 to 14 teams in the Big 12 would be pretty perfect for this league, by the way. I’m not so sure tacking $1 billion onto the bill ESPN and Fox owe everybody is the greatest idea this league has ever had (although to be fair it has had some pretty lousy ideas).As David Ubben pointed out recently, Houston is a sleeping giant and the Big 12 seems pretty insistent on awaking it. He thinks BYU and Cincinnati are the better choices. He’s probably right.I guess I’m in the “BYU and whoever” camp. I don’t know that I care about the other team. None of them excite me. None of them do much of anything for me. The proposal of OSU to the SEC with OU is a lot more fun to think about than going to Central Florida or Cincinnati every other years.If OSU wasn’t making over $30 million from being in the Big 12, you would see me Periscoping myself literally from my rooftop beseeching Burns Hargis and Mike Holder to attach the OSU wagon to literally any other conference and move on. The money continues to flow though and maybe the grass isn’t any greener elsewhere (but it probably is).last_img read more

World Cup Semifinal Crib Notes Brazil vs Germany

On Tuesday, Brazil and Germany kick off the World Cup semifinals, where there are no real party-crashers to be found. Including A Seleção and Die Mannschaft, four of the top five teams in the pre-Cup Elo ratings are still active in the tournament. Sorry, Spain.Brazil vs. Germany: 4 p.m. EDTIn BriefWith such evenly matched squads — and the ever-present specter of randomness — barring a huge blowout, the final four games of the World Cup are unlikely to provide much of a referendum on which side is truly the world’s best. But at the same time, the absence of a longshot entry boosts the chances that one of the remaining four teams is in fact the “true” best team in the field. More important, it also increases the odds that we’ll see a pair of exciting, close matches at the doorstep of the World Cup final.IN DEPTHBrazil was the World Cup favorite before the tournament began, and its championship chances still rank first according to the FiveThirtyEight model. Our official projections even say there’s a 73 percent probability that Brazil will beat Germany Tuesday and advance to the final. But those numbers don’t know that the gifted Brazilian striker Neymar will miss the rest of the tournament with a broken vertebra, an injury he sustained against Colombia in the quarterfinals. If we account for his absence (and that of his teammate Thiago Silva, who racked up two yellow cards and must sit out Tuesday’s match), Brazil’s chances of beating Germany drop to somewhere near 65 percent, numbers fueled in large part simply by the match’s location on Brazilian soil.To put it another way: If this game were staged at a neutral site, it would probably be close to a toss-up between Germany and Brazil-sans-Neymar-and-Silva.To a certain extent, that’s because Brazil has been far from dominant during its run to the semis. First, Mexico played it to a draw in the group phase, then it squeaked by Chile (on penalties) and Colombia in its knockout matches. Over the past month, the gap between Brazil’s Soccer Power Index (SPI) rating and that of second-ranked Argentina has been nearly sliced in half, despite the Argentines playing largely to expectation. That Brazil is still rated first in SPI owes as much to our prior beliefs about its strength as to anything it’s actually accomplished in the tournament.And Germany is a force to be reckoned with. While they haven’t consistently overwhelmed opponents with their ballyhooed offensive prowess (aside from netting six goals in their first two matches — including four against Portugal), the Germans have answered many of the defensive questions that surrounded them before the tournament began, keeping clean sheets against Portugal, the United States and France. And they’ll need to be staunch at that end of the pitch against a Brazilian team that still has plenty of firepower, even without Neymar.One major tactical storyline to keep an eye on will be the philosophical chess between the pass-heavy, possession-focused Germans and a Brazilian side still keenly interested in dribbling through the defense. Among semifinalist teams, only Argentina has maintained ball possession more often than Germany, and nobody makes more short passes per game than the Germans. Germany’s approach is to patiently work the ball into the opponent’s territory, passing it around until its players can create a high-percentage scoring opportunity. Brazil, on the other hand, loves to dribble the ball and create chances by taking on defenders in one-on-one situations.A compelling wrinkle will be how this changes without Neymar, Brazil’s most active dribbler. It’s likely that Hulk and Oscar will be asked to pick up some of the slack, but it will be interesting to see how Brazil adjusts its overall style in the absence of its most prolific offensive playmaker.On balance, Brazil should still be favored — if only because of home-field advantage. In close matches like this, officiating can play a sizable role, and there’s a good amount of research suggesting home teams get favorable treatment from the referees (perhaps more so in soccer than in other sports). In terms of ability, though, these two teams are very close to evenly matched.OFF THE PITCHBrazil and Germany have had good off-the-pitch relations for decades, particularly in the economic sphere. The Observatory of Economic Complexity has information on trade between the two countries that dates back to 1962, and shows that the two nations have been exchanging mostly the same stuff the whole time. Coffee, iron and soybeans were among the top Brazilian exports to Germany both in 1962 and in 2012.Similarly, machinery remains the top category of German exports to Brazil, although the specific products have changed over time. Metalworking and textile machinery reigned supreme in 1962, while cars and car parts took the largest shares of exports in 2012.But what’s most notable is how much these countries’ bilateral trade has grown. In 1962, Brazilian exports to Germany totaled $173 million and German exports to Brazil totaled $161 million. Trade in both directions surpassed the $1 billion mark in the 1970s, and was up to $11 billion in both directions in 2010, when both countries agreed to further strengthen their economic ties. Exports headed toward Germany have nearly doubled since, with $20 billion worth flowing out of Brazil in 2012. But it looks like Germany got the sweeter end of the deal, with Brazil buying $28 billion of its products the same year.FURTHER READINGIt’s a Huge Upset When All the World Cup Favorites WinHow Neymar’s Injury Affects Brazil’s Chances at the World Cup read more

Assessing the Newsstand

first_imgThe consumer magazine industry, as expected, took some huge hits at the newsstand and in overall circulation during the first half of the year, according the much-anticipated Fas-Fax report, released last month by the Audit Bureau of Circulations.Among the biggest drops in paid and verified circulation: Bauer’s Life & Style and In Touch, down 30 percent and 27.7 percent in overall paid circulation and 30.2 percent and 28.7 percent in single copy sales, respectively.Newsweek, which will see president and publisher Greg Osberg resign this fall, posted a 17.3 percent drop in single copy sales and a 12.6 percent fall-off in subscriptions. The magazine’s overall paid and verified circulation slid 12.8 percent to 2.7 million. U.S. News & World Report’s paid and verified circulation fell 10 percent.American Media Inc.’s National Enquirer saw subscription (-13.7 percent), single copy sales (-8.4 percent) and total paid and verified circ (-10.1) losses, while AMI’s Star didn’t fare much better (down 15.4 percent in subscriptions and 3.4 percent in single copy sales). Vogue’s single copy sales fell 14.8 percent and 6 percent overall during the first half, while Playboy’s single copy sales (-23.5 percent) and total paid (-6.2) saw equally pronounced declines.Holding SteadyA slew of titles managed to hold or even gain circulation while enduring the hit at the racks. TV Guide, for instance, saw its single copy sales plummet some 29 percent through June, but increased subscriptions by 2.4 percent and overall circulation by 0.3 percent.Men’s Vogue’s single copy sales dropped nearly 40 percent, but the magazine increased overall circulation by 20 percent thanks to a 43.6 percent uptick in subscriptions.Time’s single copy sales fell 7 percent, but its overall paid circulation (-0.3 percent) was left virtually untouched. Us Weekly’s single copy sales fell 10.4 percent, but its total paid circulation (0.2 percent) was flat.Martha Stewart Living fell 11.6 percent in single copy sales, but managed to increase overall circ by 1.6 percent, according to ABC. (Martha Stewart Weddings, though, slipped 7.5 percent in single copy sales and 7.5 percent overall.) The Advocate’s single copy sales fell 22 percent but the title’s total paid and verified circ increased 4.7 percent. Cookie’s single copy sales fell 19 percent, but a huge boost in subscriptions (43.1 percent) led to an overall circ gain. Entrepreneur, recently pulled off the sales block, saw single copy sales fall 11 percent, but its overall circulation decreased just over half a percent.Maxim’s single copy sales fell 11.7 percent, but its overall paid and verified circulation slid just 1.3 percent. Likewise, single copy sales for Rolling Stone slipped 6.6 percent during the first half, but overall paid circ (0.6 percent) actually increased.But the hedging works both ways. Vanity Fair increased its single copy sales 6 percent but saw paid and verified circulation drop a percentage point, thanks to a 4 percent dip in subscriptions. Sports Illustrated saw a 19.1 percent spike in single copy sales, but its overall paid circ (0.3 percent) remained essentially flat. Texas Monthly did well at the newsstand (up 16 percent) but increased its overall paid circ by just 1.3 percent. And Dennis Publishing’s The Week increased single copy sales by a whopping 62 percent—with an average of 1,820 copies per issue—but just 1.7 percent overall.Despite a fascinating Democratic primary season, The Nation’s subscriptions (down 2.6 percent), single copy sales (down 15.4 percent) and total paid and verified circ (down 2.8) all fell during the first half of the year.It wasn’t bad news for all publishers, however. OK! magazine’s single copy sales increased 19.4 percent during the first half—far and away the best performing celebrity title at the newsstand—and its total paid and verified circ 11.8 percent.The Atlantic continued its pursuit of profitability by increasing subscriptions 12.9 percent and total paid circ some 11.6 percent. And Wired increased its single copy sales (13.1 percent) and subscriptions (5.1 percent) for a 6.1 percent increase in total paid and verified circulation. Top 12 Titles Bear the BruntNearly two-thirds of consumer magazines that reported first half 2008 circulation figures with BPA Worldwide posted flat or lower circulation during the period, according to the audit group’s bi-annual report.Mature Living Choices (-29.5 percent), Cell (-18.5), California Lawyer (-15.6), American Snowmobiler (-14.9) and Sacramento (-14.7) were the largest decliners.Several titles also posted double-digit losses on the newsstand over the first half, including Florida Trend (-56.6 percent), National Fisherman (-51.1) and Restaurant Startup and Growth (-50.2). The positive standouts are Hispanic Business and Relish, which posted gains of 160.8 percent and 31.9 percent, respectively.During the first half, Meredith’s Ser Padres magazine saw overall circulation rise 41.2 percent—the largest increase of any of the 101 consumer magazines tracked by BPA.The American Journalism Review (+39.8 percent), newspaper magazine Relish (+31.9), WWE (+26.9) and the Weekly Standard (+18.1) were some of the other biggest overall BPA-audited circ gainers during the period.last_img read more

The best robot vacuums of 2019 iRobot Roomba vs Neato vs the

first_imgA home that cleans itself has been a dream for ages. Thanks to today’s robot vacuums though, that fantasy sounds less and less far-fetched. Current robot vacuums are packed with loads of sensors, electronic eyes — even lasers — and they pack enhanced computing power to match. Their prices have ballooned, too. A few models will even set you back a staggering four figures. Spending that much is extravagant, but it does net you next-level features. Those include dustbins that empty themselves, multiple room and floor mapping, plus elegantly designed hardware.To zero in on the best robot vacuum cleaners, I spent over 120 hours torture-testing a group of 10 robot vacuums. Among them are brand-new models that have recently launched, flagship products, as well as compelling options offered across numerous online retailers. I excluded older models that likely won’t be sold for long.Note that CNET may get a share of the revenue if you buy anything featured on our site.  22 • Tyler Lizenby/CNET Ecovacs Deebot Ozmo 950 18 26 71 36 39 3:43 Now playing: Watch this: Best laptops for college students: We’ve got an affordable laptop for every student.

Even though the Robovac 11s Max costs just $219, it cleans floors effectively. That’s especially the case when tackling hardwood floors. It managed to remove an average of 71 percent of our test sand from this type of surface. The robot didn’t do as well handling carpets, earning sand pickup averages of 21 and 27 percent on low pile and midpile, respectively. And due to this vacuum’s basic navigation system, it took well over an hour to negotiate our test room. Still, the Eufy used its runtime wisely. The vacuum covered the space well, leaving almost no spots untouched.      Electrolux iRobot Neato Amazon Robots Read our first impressions of the Roomba S9 Plus Neato Botvac D7 Connected 83 25 Smart Home Neato Botvac D4 Connected 54 92 Tyler Lizenby/CNET Electrolux Pure i9 Eufy RoboVac 11s Max 38 For half the price of the Roomba S9 Plus, the $647 Neato’s Botvac D7 Connected vacuums up messes almost as well. On average it picked up a greater amount of sand (36 percent) across low-pile carpet than the Roomba did. It narrowly beat the S9 Plus on hardwood floors, too, collecting an average of 95 percent of the sand we put down. The vacuum cleaned sand from midpile less effectively though, notching a pickup average of 47 percent. While it can’t match the Roomba’s prowess at removing pet hair or empty its own dustbin, it navigates more efficiently, yet covers more ground, thanks to built-in lidar laser mapping. You can also control the robot through the Neato app, as well as link it to Alexa and Google Assistant. The app allows you to designate areas of your home as off-limits, too. Legend: Sand from low-pile Sand from hardwood Sand from medium-pile Lasers, sensors and robots, oh my: Some robot vacuums… 87 37 How we test robot vacuumsOur method for evaluating robot vacuums is straightforward, yet grueling. There are two types of tests we run. The first trial is to figure out how well a robot covers the floor. We built an industry-standard testing room, as specified by the International Electrotechnical Commission (IEC), just for this purpose. The IEC is an international standards body responsible for managing robot vacuum testing procedures, among other things, for vacuum manufacturers. Enlarge ImageObstacles in out test room mimic what robot vacuums run into in the real world. Tyler Lizenby/CNET Inside this room are objects designed to simulate typical obstacles a robot encounters as it cleans. These include table and chair legs, couches, etc., plus floorings of tile, hardwood, and carpet. s9-c-useEnlarge ImageHere’s a coverage photo of the iRobot Roomba S9 Plus as it moved through our test room.

The iRobot Roomba S9 Plus costs a whopping $1,399. For that staggeringly steep sticker price though, this robot delivers superb dirt removal. On hardwood flooring it picked up an average of 93 percent of our test sand, the highest amount in our test group. The Roomba struggled a bit cleaning sand from low-pile carpeting, earning a low average sand pickup of 28 percent. That said, the vacuum removed an average 71 percent of sand from our midpile carpet. Again, this is the best result that we saw on this specific test. It also cleaned up more pet hair than any vacuum in this test group, and it navigates and maps multiple rooms and floors. The robot zipped through our test room in a short average time of 25 minutes, too. You can link the S9 Plus to the Roomba app and your home Wi-Fi as well. Best of all is the Roomba S9 Plus’ CleanBase dock. It both charges the robot’s battery and empties its dustbin automatically.

To mimic dirt of small particle size, we use a mixture of play-sand and landscaping sand. For bigger particle soil, we use grains of uncooked black rice. Robots then run in a straight line across three types of flooring (low-pile carpet, medium-pile carpet, and hardwood).robot-vac-testing-photos-1Enlarge ImageWe test robot vacuums on three types of floor surfaces. Tyler Lizenby/CNET We control for the specific nozzle width of each vacuum, too. We constructed an ajustable tool to soil our test floors. It lets us lay down a strip of precise area of soil to match the nozzle dimensions for every robot. The mass of soil isn’t chosen at random either. We measure a proportional amount that’s related to the flooring material, type of debris, plus each vacuum’s nozzle width.robot-vac-testing-photos-4Enlarge ImageOur custom-built tool lets us match soil area to a robot vacuum’s nozzle width. Tyler Lizenby/CNET We conduct three runs (at minimum) on each floor type. We also test with sand and rice separately. That comes to at least 18 tests per vacuum. We weigh the robot’s dustbin both before and after each run. From there we can calculate the percent of debris pickup for every run, and the average amount of soil a machine manages to remove. Additionally we run anecdotal (visual) pet hair tests for each robot, on all three floor types. robot-vac-testing-photos-8Enlarge ImageWe run robot vacuums in a straight line during the debris pickup tests. Tyler Lizenby/CNET The chart below shows the fine particle cleaning performance data for all of the robot vacuums we tested. It should give you a pretty good idea about their performance on different kinds of flooring. Our rice-based, medium-size particle test didn’t show enough differentiation between units, which says they can all handle larger particles without trouble. For pet hair removal we judged anecdotally. As robots move through the room, a camera overhead captures a long-exposure image of the entire room in low-light. That photo will then have a light trail, created by the LEDs, that shows exactly where the robot traveled (and its nozzle position) during its runtime. We can also see areas of the floor the vacuum may have missed.d7-c-useThis is the coverage pattern created by the Neato Botvac D7 Connected. Its movement through our test room was very orderly, logical, and effective.

Oil falls as dark clouds appear ahead of producer meeting

first_imgOil prices fell on Thursday as OPEC warned of slowing demand and Russia hinted that there would only be a loose agreement with little commitments at the upcoming exporter meeting to rein in ballooning oversupply.Meanwhile, Goldman Sachs said that productivity gains by U.S. shale producers were keeping alive its “deflationary outlook” for oil prices as drillers manage to adjust to lower prices instead of going out of business.Brent crude futures were at $43.66 a barrel at 0123 GMT, half a dollar, or 1 percent, below their last close.U.S. West Texas Intermediate (WTI) futures were also down 1 percent at $41.60.Russian oil minister Alexander Novak told a briefing that a deal on an output freeze scheduled this weekend will be loosely-framed with few detailed commitments.”The agreement will not be very rigidly formulated, it is more of a gentlemen’s agreement,” one of those present said, paraphrasing Novak’s words at the gathering.A second person present said: “there is no plan to sign binding documents.”This would make it unlikely that the meeting by top exporters in Qatar on Sunday will successfully rein in production of around 2 million barrels per day (bpd) of crude in excess of demand.Morgan Stanley said in a note that “we think any agreement actually sets up bearish catalysts for the months ahead.”With the likelihood of a binding freeze by the Organisation of the Petroleum Exporting Countries (OPEC) and Russia fading, analysts will look to the U.S. oil industry to see if lower drilling will result in falling production.Here too, the outlook is for production to remain higher than many expected.”Shale productivity gains remain a key driver of our long-term deflationary outlook for oil prices,” said Goldman Sachs.”Our analysis of shale productivity (is) broadly in line with our expectations for 3 percent to 10 percent yoy (year-on-year) increases,” it added.With no end in sight to the supply glut, much will depend on demand to determine the size of the market’s oversupply.While demand has been strong, supported largely from Asia, OPEC on Wednesday cut its 2016 forecast for global demand growth and warned of further reductions.World demand will grow by 1.20 million bpd in 2016, OPEC said in its monthly report, 50,000 bpd less than expected previously.”Economic developments in Latin America and China are of concern. Current negative factors seem to outweigh positive ones and possibly imply downward revisions in oil demand growth.”Morgan Stanley pointed to several bearish risks for oil, including “significant selling pressure from producer hedging if prices rise (and) reemerging macro headwinds.”The bank said it was “bearish oil prices into 2H16” and that “sustaining a price above $45 WTI in the front will be difficult into 2017.”last_img read more

Scientists rediscover selfhealing silicone mechanism from the 1950s

first_img New nanotube material stays rubbery over a more than 1,000 degree temperature range The researchers, grad student Peiwen Zheng and Professor Thomas J. McCarthy from the University of Massachusetts, have published a paper on the rediscovery of siloxane equilibration in a recent issue of the Journal of the American Chemical Society.“We have been working on silicone materials from a couple of different perspectives,” Zheng told “When we rediscovered the forgotten unusual properties of silicones and combined them with today’s research interests, we found that the silicone material with the siloxane equilibration was an obvious candidate for a self-healing material.”The researchers performed several experiments to test the theoretical predictions from papers published in the early 1950s, as well as to extend some of the experiments performed at that time. In one experiment, Zheng and McCarthy prepared a siloxane-based mixture containing a cross-linking agent and a catalyst. Then they poured the solution into molds of various shapes, such as cylinders, disks, and dog bones. After heating the molds at 90 °C (194 °F) for four hours, the researchers removed clear, rubbery silicone shapes from the molds. The scientists described these silicone samples as “living polymer networks.” More information: Peiwen Zheng and Thomas J. McCarthy. “A Surprise from 1954: Siloxane Equilibration Is a Simple, Robust, and Obvious Polymer Self-Healing Mechanism.” Journal of the American Chemical Society. DOI: 10.1021/ja2113257 ( — Research in self-healing organic polymers has grown recently, but one simple self-healing mechanism from more than 60 years ago has been nearly forgotten until now. Using this mechanism, which is called “siloxane equilibration,” scientists have demonstrated that silicone rubber that has been cut in half with a razor blade can completely repair itself through heat-activated reversible bonding. The self-healing mechanism could have applications in a variety of areas, such as for designing self-healing surfaces of vehicles and countertops.

Image credit: Zheng, et al. ©2012 American Chemical Society “The silicone network is at a chemically anionic equilibrium,” Zheng explained of the term, “where the reactive center will cleave and reform a covalent siloxane bond.” These bonds are reversible, which enables the two sides of a crack to reconnect under the right conditions.To demonstrate the self-healing ability, the researchers cut a 1-cm-long cylindrical sample in half using a razor blade. Then they rejoined the two pieces by wrapping them together with Teflon plumbing tape and heating them in an oven at 90 °C (194 °F) for 24 hours. When the researchers retrieved the sample and removed the tape, they found that the silicone cylinder had completely healed. Then they bent the cylinder by hand until it broke again – significantly, it broke in a different location than where it had been cut. The scientists repeated this experiment on different shaped objects with the same results. This document is subject to copyright.

Journal information: Journal of the American Chemical Society In another experiment, the researchers molded a silicone dog bone, which they cut into multiple pieces. Then they rearranged the pieces to fit into a mold of a dog. Heating the sample resulted in a silicone dog with no visible fractures or weak spots where the pieces had been fitted together.The researchers also quantified the strength of the healed samples in comparison with the original samples using fracture toughness measurements. The data for the two types of samples was indistinguishable, indicating exceptional self-healing.The researchers explained that, in principle, any cross-linked dimethylsilicone elastomer (only one type was used here) can be converted into a living elastomer by the addition of basic catalysts. This possibility opens up many different routes for synthesizing a variety of self-healing silicione-based materials. While the samples used here required applied heating to self-heal, the researchers predict that samples in a sealed, high-temperature environment would self-heal “autonomically,” or automatically. Zheng explained that self-healing materials, with some improvements, could lead to a variety of applications.“It can be developed into self-healing coatings on auto vehicles or countertops,” she said. “It is also a ‘plastic’ elastomer which can be used in molding to form desired shapes and patterns. The concept of a self-healing silicone can be used to guide the preparation of elastomers with gradient modulus, Janus elastomers, reversible surface patterns when filled with magnetic particles, and super tough materials which can chemically relax stress.” Explore further (A) A silicone sample in the shape of a cylinder.

Daedalus catches cyberattacks realtime

first_img NASA computer servers vulnerable to attack: audit According to a NICT video on DigInfo TV, “the sphere in the center represents the Internet, and the circles moving around it represent networks under observation. The state of an attack is shown using 3-D graphics, and can be viewed from any perspective.”Today’s cyber-attacks represent an assortment of malware via USB memory stick, mail attachments, and zero-day exploits. Daedalus can act as an alert system for the cyber-attacks; it can see if a USB flash drive with a virus infects a machine, for example. Daedalus can identify and isolate the malignant traffic on-screen, sending an email to support staff and displaying a red alert through its user interface.Further descriptions of an attack showing up realtime are provided in the video demo:”The blue part in this organization shows IP addresses that are used, and the black part shows addresses that are not used. This character indicates an alert. When you click on the alert, a message showing the cause appears. In this case, only two packets have been sent. But because the packets go from an address that’s used to an address that’s not used, this indicates that a virus is starting to spread within the organization.” The system sends out an alert, saying, ‘This IP address of yours is spreading a virus using this protocol at this time’.”Daedalus is designed to be used together with conventional systems, to improve network security within organizations. “We previously created a system called nicter for observing cyber-attacks. We also built an observation network in Japan, called the Darknet Observation Network, to cover IP addresses not used in nicter,” said a NICT source in the video. The nicter is a system for early detection and in-depth analysis of cyber-attacks. That word stands for Network Incident Analysis Center for Tactical Emergency Response. NICT is to provide Daedalus free of charge to educational institutions where nicter sensors can be installed. NICT will also transfer access to the system to Clwit, a company described as a Tokyo-based business providing Internet security countermeasures. According to reports, Clwit will develop it into the product, SiteVisor. Where administrators may have to comb through hundreds of lines of server logs to isolate a problem, the Daedalus system can reveal where attackers are focusing their flood of packets, as a stream of arrows moving along iridescent lines. Explore further More information: ( — Japan’s National Institute of Information and Communications Technology (NICT) has developed a national cyber-attack alert system that can render network attacks as visible in realtime. The system, announced earlier this month and showcased at Interop Tokyo 2012, is called Daedalus, standing for Direct Alert Environment for Darknet and Livenet Unified Security. The system views computers for any suspicious activity and if it spots an attack it can visualize its progression as it moves through the network.

Understanding Youth Culture Is the Key to Success in 2019 and Beyond

first_imgNovember 28, 2018 Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now 4 min read Jane Buckingham started trend-hunting at age 17, when she wrote her first book, Teens Speak Out. Some three decades later, she’s still hot on the scent — and still hanging out with teens, because doing so provides a keyhole view of the future. “They’re not so set in their ways, so that’s where you see change happening,” Buckingham says. The firm she founded in 2009, Trendera, forecasts what’s next through deep research and consumer surveys on everything from technology to gender fluidity. Entrepreneurs should pay particular attention to shifts in culture, she says, “because when attitudes change, there’s always opportunity.”Related: The Young Founder of This Celebrity-Loved Activewear Company Shares Why You Should Always Trust Your InstinctsWhat macro trends are you seeing in 2019? Entertainment is all about to change. Youth culture is where trends often take root. There’s a company called Brat that’s doing 10- to 15-minute shows online for teens. Let’s call it a Sweet Valley High meets Riverdale. They’re acting like a TV channel but using social media as direct marketing and making it the primary draw. They’re getting, like, two million views an episode. I think we’ll see a shift to our phones as our central entertainment system. That’s a huge opportunity. Give us another big trend.“Have it your way” to the 98th degree. “I want what I want, when I want it.” On-demand and personalizing will trump everything. For example, cars are one of the least customizable big purchases. I have to imagine that’s an area that could ultimately explode. One of Trendera’s reports this year talks about self-protection.We’re entering an unfortunate period of totally excused bad behavior. We’re going to see more safeguarding developments — whether it’s a nail polish that tells you if your drink has been roofied, or a digital contract that allows college students to tape themselves during sex so they can prove it wasn’t rape.Related: Isn’t It Time to Be Your Own Boss? These Women-Founded Companies Want You to Join the Movement.Are you making this up? Oh, totally! I don’t know what that looks like, but people will become self-­protective. But a more positive trend is health. Aren’t we already obsessed with health?What’s new is the integration of wellness into everything — from work to school to food to parenting. It’s one of the few things we feel we can control, so it’s a gold mine for entrepreneurs.What’s in your crystal ball with tech?Have you seen this workout device called Mirror? You work out in front of it with a virtual trainer in the mirror showing what to do. That’s going to be the next evolution. So you’re going to have technology in your kitchen where someone walks you through the recipes, and tech where someone scans your closet and tells you, “Oh, you know what would be a great outfit for today?” Related: Millennial Women Are Facing Serious Burnout — Here’s How to Beat ItAre you seeing opportunities to invent these tech products or use them? Both. There are tons of areas for entrepreneurs to ask: How do we make technology feel more human by incorporating people? And on the business side, it’s everything from better bots to better customer service to better shipping and delivery. It’s all going to just get more connected.  That sounds great.Till the robots overtake us. Because we really have seen this movie, right? We all know how it ends [laughs]. This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. This story appears in the December 2018 issue of Entrepreneur.
