White roofs streets could curb global warming

first_imgThe idea of painting our roofs and roads white to offset global warming is not new, but a recent study has calculated just how significantly white surfaces could impact greenhouse gas emissions. Last week, researchers at Lawrence Berkeley National Laboratory and UC Berkeley presented their study at California’s annual Climate Change Research Conference in Sacramento.

New report compares economic payoffs If the 100 largest cities in the world replaced their dark roofs with white shingles and their asphalt-based roads with concrete or other light-colored material, it could offset 44 metric gigatons (billion tons) of greenhouse gases, the study shows. That amounts to more greenhouse gas than the entire human population emits in one year, according to a recent article in the Los Angeles Times. The strategy could also offset the growth in carbon dioxide emissions, which account for about 75% of greenhouse gases, for the next 10 years.The reason for white is simple: white reflects the sun´s rays more than black does. The study´s coauthor, LBNL physicist Hashem Akbari, explained that it takes about 10 square meters of white roof to offset 1 metric ton of carbon dioxide. In warm climates, white roofs have the additional benefit of lowering the cost of air conditioning by up to 20% in hot months.It´s this second reason of reduced cooling costs that prompted the state of California to require in 2005 that flat-roofed commercial buildings have white roofs. In 2009, the state will require that new and retrofitted residential and commercial, with both flat and sloped roofs, be installed with heat-reflective roofing. The requirements are part of California´s energy-efficient building code.Globally, roofs account for about 25% of the surface of most cities, and pavement accounts for about 35%. Even without cutting industrial pollution from current levels, installing white roofs and pavements could offset more than 10 years of emissions growth, according to the conference data. Economically, the scientists estimate that white roofs and roads could save billions of dollars per year in reduced carbon dioxide emissions. Besides offsetting global warming and reducing cooling costs, white surfaces offer a third benefit: they could cool a city by a few degrees, which dramatically reduces smog.The LBNL physicists plan to work with the United Nations to persuade the world´s major tropical and temperate cities to adopt white roofing and pavement strategies.Akbari, along with coauthors Surabi Menon of LBNL and California Energy Commissioner Arthur Rosenfield, will publish the study, called “Global Cooling: Increasing Worldwide Urban Albedos to Offset CO2,” in an upcoming issue of the journal Climate Change.More information: Global Cooling Presentationvia: Los Angeles Times center_img Explore further Citation: White roofs, streets could curb global warming (2008, September 17) retrieved 18 August 2019 from https://phys.org/news/2008-09-white-roofs-streets-curb-global.htmllast_img read more

Programmer has fun with monkeys typing Shakespeare theory

first_img Anderson isn’t testing the theory with real monkeys, that whole idea was pretty much laid to rest when researchers a while back gave a group of monkeys a keyboard and after month of effort found they had little more than an affinity for the letter “S” and disdain for modern contrivances (they urinated on it). Instead he’s using virtual monkeys on computers and a mathematical algorithm to pick out letter sequences typed at random. He started last month, using Amazon’s SC2 cloud computing system and has already put together one of the Bard’s poems, though it is difficult to ascertain from the experiment just what exactly is being proved. That typing nine random characters as a group will eventually reproduce a nine letter sequence that duplicates nine letters of something Shakespeare once wrote? That piecing such sequences together will eventually result in the whole work being reproduced? Interesting, but hardly science. But then, Anderson, a homespun programmer, clearly isn’t trying to shake up the world. He’s just trying to have some fun. Less Technical Explanation Citation: Programmer has fun with monkeys typing Shakespeare theory (2011, September 28) retrieved 18 August 2019 from https://phys.org/news/2011-09-programmer-fun-monkeys-shakespeare-theory.html Infinite Monkey Technical Discussion What’s perhaps more interesting are the reactions to his efforts from bloggers and reporters for various media and science outlets, especially those that seem to want to point out how proving the theory right or wrong would take more time than we humans will ever have; which seems premature, when you consider that the theory does say something about using an infinite number of monkeys after all. Surely using some bit of calculus would show that as the number of monkeys approaches infinity, the number of completed works would be go up pretty quickly as well. Seems to me if you went that route, you could have the whole job done before breakfast. At any rate, the whole point is rather moot, isn’t it? After all, does it really matter if monkeys typing randomly could randomly reproduce anything all? A more important question would seem to be, if you could get monkeys to type, wouldn’t they eventually, given enough time, tell us all what they really think of us and our crazy use of them for our own experimental purposes? Explore further (PhysOrg.com) — Sometimes you just have to shake your head at some experiments done in the name of science, and go with the flow, or as Jesse Anderson puts it on his blog, “Keep Calm and Carry On.” He’s conducting an experiment, for fun, to see if he can reproduce some part of the old philosophy question of whether putting infinite numbers of monkeys before infinite numbers of typewriters, working indefinitely, would at some point result in the reproduction of the entire works of Shakespeare. Anderson’s efforts have created quite a stir on Internet, though for different reasons. Some see the humor in his approach, others point out how his efforts aren’t really proving anything at all. © 2011 PhysOrg.com Modern society made up of all types This document is subject to copyright.

Powerstrip lookalike hacks office networks

first_img Citation: Power-strip lookalike hacks office networks (2012, July 23) retrieved 18 August 2019 from https://phys.org/news/2012-07-power-strip-lookalike-hacks-office-networks.html The device has Bluetooth and Wi-Fi adapters, a cellular connection, dual Ethernet ports, and hacking and remote access tools that let security professionals test the network and call home to be remotely controlled via the cellular network. The device comes with easy-to-use scripts that cause it to boot up and then phone home for instructions. A “text-to-bash” feature allows sending commands to the device using SMS messages. Power Pwn is preloaded with Debian 6, Metasploit, SET, Fast-Track, w3af, Kismet, Aircrack, SSLstrip, nmap, Hydra, dsniff, Scapy, Ettercap, Bluetooth/VoIP/IPv6 tools and. It really can function as a 120/240v AC outlet strip.The Power Pwn has funding from a new Defense Advanced Research Projects Agency (DARPA) program called Cyber Fast Track (CFT), which is looking to advance new cyber-defense tools. The officially stated purpose of CFT is to fund research to be performed by boutique security companies, individuals, and hacker/maker-spaces, and allow them to keep the commercial intellectual property for what they create. While the purpose is to place this in the right hands for identifying network weaknesses, Tony Bradley of PCWorld is asking what about the device landing in the wrong hands, as an attacker could communicate with the device from inside the network or around the world. The device can, after all, bypass Network Access Control and other security measures in place to keep unauthorized devices off the network. It can tunnel through firewalls, he notes, maintain an encrypted connection to the attacker, and operate in stealth mode. “The fact is that any attacker with $1,300 can buy one and surreptitiously plant it in your office,” he said. His advice for those in business settings is to check out and mark their office surge protectors and strips and allow only approved power strips to be in the inventory. The testing platform covers the range from physical to application layers. Pwnie Express is taking pre-orders for the device with a pricetag of $1295 and an estimated ship date of September 30.The Pwnie Express product description says it is a first-to-market “commercial penetration testing drop box platform” for remote security testing of corporate facilities, including branch offices and retail locations. (Phys.org) — Pwnie Express, the company specializing in cyber security products, calls its new device “ingenious.” Bloggers hearing about it are paying attention to the fact that it is a power-strip lookalike but with far more ambitious intentions, such as stealth-penetrating a corporate network. Power Pwn is the name of the little device for security testing on corporate networks. It looks like an under the office desk power strip.

Research pair find nitric oxide governs fightorflight response in crickets w video

first_img Play Movie of two male crickets fighting. The first part shows their first fight, which establishes a clear winner and a loser, and the second part shows reengagement of the loser (left) with the previous winner two minutes later. Note the loser avoids all contact with the winner (post-conflict depression of aggression – or loser effect). Stevenson and colleagues show that this effect is due to the gaseous modulator nitric oxide (NO). Credit: Paul A. Stevenson and Jan Rillich The fight-or-flight response is well documented in a wide variety of mammals, including humans. It has also been found in insects. Still, how it works exactly continues to be a mystery. Suspecting it might have to do with brain chemicals, Stevenson and Rillich focused on one brain chemical in particular: nitric oxide. It has been shown to speed up snails and to impact behavior in other animals. To find out if it might have an impact on the flight-or-flight response, the team decided to test its impact on Mediterranean field crickets, which are well known for their animated brawls.Prior research has shown that when fighting, nitric oxide is generated in the brains of the crickets, though its purpose has been a mystery. To learn more, the researchers put test crickets in a box and filmed them as they grew aggressive and fought and continued filming until one or the other of the crickets gave up and ran away. To test the impact of nitric oxide on the crickets, the researchers conducted experiments where one or both had more or less of the chemical introduced artificially into their brains, and then watched to see how it impacted their behavior. They found that adding more of the chemical tended to switch on the flight mechanism—the cricket would stop fighting and run away, and would continue to cow before the other cricket until the chemical was naturally washed out of its system (or was blocked artificially by the researchers). Conversely, they found that restricting the chemical tended to cause the crickets to be even more aggressive and to keep on fighting longer.It is not known of course if the same response might occur in mammals, particularly humans, but the idea is interesting—perhaps someday soon, instead of tossing teargas into rioting crowds, police officers can instead toss nitric oxide bombs that will cause everyone to give up the cause and run home.

By manipulating aggressive signaling and applying nitrergic drugs, we show that the evolutionarily conserved neuromodulator nitric oxide (NO), which has a suppressing effect on aggression in mammals, can play a decisive role. We found that crickets, which exhibit spectacular fighting behavior, flee once the sum of their opponent’s aversive actions accrued during fighting exceeds a critical amount. This effect of aversive experience is mediated by the NO signaling pathway. Rather than suppressing aggressive motivation, NO increases susceptibility to aversive stimuli and with it the likelihood to flee. NO’s effect is manifested in losers by prolonged avoidance behavior, characteristic for social defeat in numerous species. Intriguingly, fighting experience also induces, via NO, a brief susceptible period to aversive stimuli in winners just after victory. Our findings thus reveal a key role for NO in the mechanism underlying the decision to flee and post-conflict depression in aggressive behavior.

Metallic all the way

first_imgKickstart the year with a bang. Metal Battle I looks like it is going to be a treat for all headbangers. Amidst all the tributes, alternate rock music and the progressive sorts, Metal Battle I seems to be dedicated to the real rockstars over one evening.The gig brings together four bands on this debut installment — Heisenberg, Silent Existence, Jehova and Winter Gate. These four bands will be performing back to back in the Capital this weekend.While Heisenberg (the name comes from the love the band has for quantum physics, claim the band), formed in 2010, experiments with jazz and indian classical influences in metal, Silent Existence is about ‘new metal’. Also Read – ‘Playing Jojo was emotionally exhausting’Jehova hopes to get the attention with their ‘signature stage act’ and Winter Gate claims to have transformed from a ‘thrash metal outfit to a thrash geath joint until they finally evolved into pure and progressive death metal.’Silent Existence has a name for itself already and Jehovah is touted to be one of the freshest acts on stage. But Winter Gate and Heisenberg are in no mood to play second fiddle. This is perhaps the first all metal gig to hit the city where four bands will be taking the stage and they are all pretty pumped to get their acts on. While there are no specific collaborations on the cards, with young talent on stage – an interesting mix and match of styles cannot be entirely ruled out, we say!While most of the bands are either prepping for their original albums or rocking away in studios on original compositions, a lot of what Metal Battle hopes to get on stage. So head over this Sunday for some good old headbanging.DETAILAt: Cafe Morrison, E-12, South Extension Part 2 Market When:20 January Timings: 7 pm to 10 pm For Reservations, Call: 9910039456last_img read more

Eat seafood meal once a week to stay sharp

first_imgIncluding seafood or other foods containing omega-3 fatty acids at least once a week in your diet may protect against age-related memory loss and thinking problems, says a study.The age-related memory loss and thinking problems of study-participants, who reported eating seafood less than once a week declined more rapidly compared to those who ate at least one seafood meal per week.“This study helps show that while cognitive abilities naturally decline as part of the normal ageing process, there is something that we can do to mitigate this process,” said study senior author Martha Clare Morris from Rush University Medical Centre in Chicago, US. The findings were published online in the journal Neurology. The researchers followed 915 people with a mean age of 81.4 years for an average of five years.  At study enrollment, none had signs of dementia. Also Read – ‘Playing Jojo was emotionally exhausting’During the course of the study, each person received annual, standardised testing for cognitive ability in five areas — episodic memory, working memory, semantic memory, visuospatial ability and perceptual speed. The study group also completed annual food frequency questionnaires, allowing the researchers to compare participants’ reported seafood intake with changes in their cognitive abilities as measured by the tests.The questionnaires included four types of seafood: tuna sandwiches; fish sticks, fish cakes and fish sandwiches; fresh fish as a main dish; and shrimp, lobster and crab.   Also Read – Leslie doing new comedy special with NetflixThe participants were divided into two groups: those who ate at least one of those seafood meals per week and those who ate less than one of those seafood meals per week. People who ate more seafood had reduced rates of decline in the semantic memory, which is memory of verbal information. They also had slower rates of decline in a test of perceptual speed, or the ability to quickly compare letters, objects and patterns, the findings showed.Seafood is the direct nutrient source of a type of omega-3 fatty acid (docosahexaenoic acid) that is the main structural component of the brain.last_img read more

Low love hormone levels less empathy

first_imgPeople suffering from medical conditions causing low levels of oxytocin – love hormone – perform worse on empathy tasks, reveals a new research.Oxytocin is often referred to as the ‘love hormone’ due to its role in human behaviours including sexual arousal, recognition, trust, anxiety and mother-infant bonding. It is produced by the hypothalamus – an area of the brain that controls mood and appetite – and stored in the pituitary gland, a pea-sized organ that sits at the base of the skull. Also Read – Add new books to your shelfIn the study, researchers from the University of Cardiff, Wales, investigated empathic behaviour in people who they suspected of having reduced oxytocin levels due to one of two medical conditions caused in response to pituitary surgery.The findings revealed that CDI and HP groups performed significantly worse on empathy tasks, compared to controls. In particular, CDI participants with the lowest levels of oxytocin produced the worst performances. Researchers said this is the first study which looks at low oxytocin as a result of medical, as opposed to psychological, disorders. Also Read – Over 2 hours screen time daily will make your kids impulsive“If replicated, the results from our patient groups suggest it is also important to consider medical conditions carrying a risk of low oxytocin levels,” said Katie Daughters from the University of Cardiff. Further, patients who have undergone pituitary surgery, and in particular those who have acquired CDI as a consequence, may present with lower oxytocin levels. This could impact on their emotional behaviour, and in turn affect their psychological well-being, Daughters added.last_img read more

The Stunning Gokstad Ship – Best Preserved Viking Vessel in Existence

first_imgOne of Norway’s greatest archaeological finds is the Gokstad ship which takes us back to the late 19th century when two youngsters reportedly decided to have some fun by starting to dig in what people of the area called “the king’s mound.” A prominent mound indeed, its location was a farm in the Sandefjord municipality, slightly to the southwest of Oslo. The boys who started the dig in 1879 were just curious to see what they’d find. Whether the boys had a gut instinct that they’d find something as spectacular as a well-preserved Viking ship, we cannot know, but they were digging in the right spot. The news of their find, what was later named the Gokstad ship, traveled fast. By early 1880, the new archaeological site was visited by representatives of the antiquity department at the University of Oslo, and the excavation process proceeded with more care and caution.Gokstad ship, Kulturhistorisk museum (Viking Ship Museum), Oslo, Norway.The vessel remnants turned out to be those of a ship from the Viking days, in quite good condition except for its upper parts and both the bow and the stern, which had rotted as they stuck out of the burial mound. The mound, made from clay and peat, would originally have been bigger, but its proportions were fairly large even at the time of the digging, some 16 feet high with a diameter measuring about 147 feet.Gokstadskipet, Vikingskipmuseet, Oslo, Photo by Karamell, CC BY-SA 2.5Made of oak, the remains of the Gokstad ship extended almost 52 feet wide and 75 feet in length. There are 16 oar mounts on each side of the vessel; along with the helmsmen, as well as the lookout, a crew of 34 in total would have sailed this Viking boat. The mission could have been trading affairs, or perhaps an adrenaline-filled Viking raid mission.When a replica of it was made named Viking, it embarked on the journey across the Atlantic Ocean from Norway to the United States to be displayed at the 1893 Colombian Exposition in Chicago. The replica testified to the fantastic seafaring capabilities of the Viking vessel, and it continues to rest on display close to Chicago.The original vessel retrieved from the burial pit underwent extensive restoration. The artifact is nowadays the most admired piece that visitors can see at the Viking Ship Museum in Oslo.A photograph from the 1880 excavation of the Gokstad vesselPerhaps more fascinating than the vessel finding is the fact that it was a burial site, with a chamber where, as archaeologists concluded, a very prominent person from the Viking times was entombed. Archaeologists believe this was a man of power because of accompanying artifacts buried in his grave.A sumptuous tapestry interwoven with silk and gold thread decorated the chamber where the remains of the Gokstad man were found. The man was laid to rest on an elegant bed inside the burial chamber–it is assumed he would have been buried with weapons and some jewels too, but these have probably been lost to grave robbers.The Gokstad ship was deposited in the burial pit sometime around 900 A.D., and analysis of the skeleton shows the Gokstad man was middle-aged, probably in his 50s, when he died a violent death, receiving a knife wound in his right thigh.Model of the Gokstad ship. Photo by Softeis CC BY-SA 2.5Two more injuries have been detected on his legs, which suggest the man was hurt in a battle. That the man received such high praise, being buried with a huge Viking vessel, indicates he was an affluent person of power, perhaps even somebody with a royal lineage, but his identity has not been resolved.As the vessel was unearthed, 32 shields painted yellow and black attached to its sides resurfaced as well. Archaeologists also identified the leftovers of the ship’s sail, remnants of white woolen cloth with strips of red. While precious possessions such as gems and jewels had been emptied from the site, as the UiO Museum of Cultural History writes, there were still other grave goods, including “a gaming board with counters of horn, fish-hooks, and harness fittings made of iron,” among others.More findings included “12 horses, eight dogs, two goshawks and two peacocks,” the latter of which could have even been collected as war trophies, the museum page writes.The Gokstad ship’s replica, the Viking, as seen at the World’s Columbian Exposition, Chicago, in 1893A later discovery of a large marketplace not very far from where the Gokstad ship and man were found indicates that the wider area was a well developed trading hub of the Viking days. The artifacts found in the Gokstad burial mound also hint that even if the Gokstad man weren’t any kind of ruler or royal, he would have at least been a wealthy tradesman. His burial ship would have been produced some 10 years before he died, around 890 A.D.Related story from us: Vikings had cats on board their ships as they set sail to conquer the worldWhen Viking enthusiasts check out the legendary ship in Oslo’s Viking Ship Museum, they will notice there is another amazing Viking vessel called the Oseberg ship close to the Gokstad one. This second ship was reportedly discovered in the early 20th century together with the skeletons of two women.last_img read more

Wish Waiting for a Table Was Less Painful Theres an App for

first_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. When Taiwanese restaurant chain Din Tai Fung needed a more efficient way to manage the hourlong waits for tables at its U.S. locations, it turned to mobile tool NoWait. “Our locations seat as many as 2,000 guests a day,” says Aaron Yang, partner and operations manager for Din Tai Fung USA. “NoWait has become essential to help us, and we’ve gotten very positive feedback from both hosts and guests. We’re definitely seeing a decrease in wait time.”The dumpling specialist, which has locations in 10 countries, is now using NoWait in all six of its U.S. restaurants.Robb Myer conceived NoWait after one too many holdups at his favorite eateries. Formerly a director at an employee-benefits and consumer-health company, Myer teamed up in 2010 with developers James Belt and Richard Colvin and marketer Luke Panza to launch their NoWait host app for the iPad, which moves traditional restaurant wait lists from paper to tablet.Arriving customers provide the restaurant host with a cell number and receive a text message confirming their spot on the wait list. When their tables are ready, customers are notified by another text; the setup gives them the freedom to leave while they wait, without having to carry a pager from the restaurant.On the restaurant side, the service provides hosts with a running clock on each individual party, as well as a floor map of the establishment with progress bars that indicate when tables will open up. At the end of each day, NoWait sends the restaurant manager an e-mail summary with analytics about seating totals, wait-time quote accuracy and the number of parties that left or were removed from the list. In February, Myer and his Pittsburgh-based team launched a free consumer-facing version of the app for iOS and Android that can be used to add a name to a list or to check wait times. It also has a “suggest a restaurant” feature that encourages diners to vote for eateries that should use the service. Within the first three months, the feature generated 80,000 votes for 13,000 U.S. restaurants.NoWait says it is seating 5 million guests per month, up from 700,000 per month in 2012. Restaurants that use the system “can turn their tables faster and ultimately seat more guests,” Myer claims. “We see a 15 percent increase in revenue after the implementation of NoWait at a restaurant.”NoWait is free for use by restaurants that seat up to 200 parties per month; the standard package covers 1,200 parties for $119 per month and includes additional features such as text-message customization, two-way texting and a wait-time predictor. An enterprise option, available for large clients, has been implemented by the Buffalo Wild Wings, First Watch and On The Border chains.Next up for NoWait, which has received more than $15 million in funding from investors such as Birchmere Ventures and Drive Capital, is to expand beyond restaurants to markets such as doctors’ offices. Now that’s an innovation worth waiting for. Take a seat: NoWait’s Robb Myer.Photo © Billy Delfs August 14, 2014 3 min read This story appears in the August 2014 issue of .

5 Ways the Best Board Members Will Add Value to Your Startup

first_img When most entrepreneurs raise venture capital funding, they’re focused on getting the best valuation and deal terms for their company. And that makes sense: Reducing the cost of capital is urgently important for growing a business efficiently and preserving as much founder equity as possible.Related: Getting the Most From Your Startup’s Board of DirectorsBut you might also want to pay attention to the other side of the aisle: Because while you, as the business owner, need to understand any investment you accept, in terms of efficiency and equity, it’s equally important that you understand it from a lead investor’s perspective.This need is particularly acute if the investment is tied to the creation of an outside board seat, which typically occurs in institutional funding rounds.According to a variety of studies including one by MSCI/GMI Ratings, a well-constructed board, over time, leads to increased shareholder value. And this positive effect undoubtedly spills over into private companies, since these boards arguably have even more influence given their smaller average size.So, in setting up your own board of directors, think what expectations you, the entrepreneur, should have. Below are five meaningful ways in which the “right” board directors can positively impact your business’s value.DisciplineThere are many operating goals that startups pursue at any given point: These may be related to product development, marketing and sales, operations or finance. The result is that management gets distracted with the day-to-day vagaries of running the business. This is where a productive board can help: It not only helps the executive team prioritize goals but also serves a role in ensuring that there is follow-through.Also for a productive board: Agendas flagging the most important topics are established and tracked during, and in the time between, board meetings.Related: 5 Best Practices When Bringing on and Working With AdvisorsIn this context, it would be reasonable to assume that the agenda for, say, Uber, focused on different priorities at different times of the company’s growth: These might have included geographic expansion, inside and outside the United States; regulatory strategies; and, more recently, company culture and how best to deal with change in its executive ranks.Access to capitalEstablished investors, whether they’re funds or individuals, tend to have existing relationships with counterparts they have previously invested with. This network allows them to access relationships that represent additional funds and facilitate “syndicating” a deal.For an entrepreneur, this can not only help accelerate the closing of a current round, but also make it easier to tap into dollars in future rounds. It is common for angels and seed funds to work with a short list of trusted co-investors. When I was a board director at SeatGeek, the company relied heavily on its network investors, including Founder Collective, to set itself up for subsequent round of financings, attracting such investors as Accel Partners and Technology Crossover Ventures.Strategy While startups have certain things under their control, external market forces can impact the initial assumptions being made about these startups’ industry or business. New technologies, changes in customer behavior, regulatory changes and competitive pressures are among the meteors that can strike at any time.That’s why a healthy board contributes by providing a channel for entrepreneurs to brainstorm strategic issues, such as a discussion on business lines, business models, pricing and funding strategies. Of course, the expectation should be that the board provides a conversational framework rather than outright makes company decisions. An extreme example of this is the proverbial “pivot.”Many folks do not know that YouTube started out as a video dating site or that Twitter early on was a podcasting network. In most cases, these 90-degree turns are done with investor input.Business developmentA company can never have enough relevant customers or commercial partners, especially in the early days as it’s getting its sea legs. Funds in particular can open doors to prospects that help drive revenue. Many times, these contacts are at the highest levels of an organization, which helps draw immediate attention and establishes credibility to begin a serious dialogue.The more investments an investor has made, and the bigger his or her portfolio is around a particular industry, the wider this person’s commercial Rolodex is likely to be. A particular benefit here can be a corporate venture fund that supplements the investment with access, for the startup, to its customer base or internal organization.It’s not unusual, in fact, for funds like Comcast Ventures or Time Warner Investments to become customers of, or partners to, startups in which they invest.Access to talentIn the end, startup success is a direct function of the people inside a company who execute an ambitious vision. Not surprisingly, finding and retaining high-performing personnel across all functional departments is difficult and can be a limiting factor. Board members understand this and can be valuable sources of leads to help fill particular roles, especially at the executive level.Being able to recruit a qualified candidate endorsed by an investor can reduce your interview cycles and snag talent that might otherwise be unattainable. In fact, VC funds like FirstRound Capital and FF Ventures have recruiters on staff to help their portfolio companies identify candidates, to fill their open slots across multiple departments, including sales, marketing, technology and operations.Related: 3 Ways VCs Can Add Value to Your Startup Beyond the CashThe message here? When scouting for lead investors, consider more than just the economics of that deal . Take into account the potential board impact to come after the transaction. That’s when the real fun begins. 5 min read Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals August 1, 2017 Opinions expressed by Entrepreneur contributors are their own.

How to Make Your Tech Platform Better Than the Competition and Dramatically

first_imgNovember 7, 2017 Enroll Now for Free Opinions expressed by Entrepreneur contributors are their own. Do you remember the days when you used to have to call a travel agent to make travel accommodations for you? There was no digital interface, no travel package option on your smartphone, no live chat to answer questions. Today, we have access to technology that has made booking travel an almost entirely self-service experience. This has created an ecosystem of tech solutions for those in the travel space to provide efficient and productive service to their clients and a plethora of options for travelers.Now, with so many websites, apps and other technology solutions in the travel space, the game is on to provide the best digital travel experience to customers. Travel agencies today are looking to streamline every facet of the travel experience. That’s everything from customer acquisition and retention to premier customer service at an economic price. Related: How This Social Network Helps You Capture The Best Travel StoriesSo how can travel agencies use tech to set themselves apart in a saturated market? And how can you apply these lessons from the travel industry in your own crowded digital marketplace? I spoke with Daniel Nelson, executive chairman of Travel Pass Group, which books 10,000 room nights per day and has surpassed $2 billion in gross hotel booking revenue across its travel-related websites. Nelson credits this rapid growth in large part to the tech TravelPass uses. Here’s his advice to set yourself ahead of your competition. 1. Focus on milliseconds. Most of the challenges faced by travel agencies today concern making information accessible. Every day, they work with a rushed customer base that demands results in milliseconds. “Speed wins! Plain and simple,” says Nelson. “Our goal is to deliver an experience at the speed of thought. That’s how we define a win.” (It is Amazon-like, where the customer never has to wait but is given the desired options and experiences.)Key to remember is that technology does not replace human interaction — it enhances it. As Zach Smith, cofounder of Anywhere, states, technology equips teams to  “focus on empathetic communication and solutions… to create an authentic, human travel experience. The value is the difference between interacting with robots versus human intelligence.”  When you can give your client an immediate search result and enhance the communication experience, you’ve got a recipe for success.Related: Corporate Travel Segment in India Has Incredible Potential. Here’s Why.2. Shoulder the tech burden for your clients. In the travel industry, hotels and suppliers often have slower legacy systems that cannot perform with the speed that consumers have come to expect. In addition, they are unable to make that digital transformation in-house to sync properly with state-of-the-art travel sites. So Nelson’s team enhances the systems. “We’ve developed capability in taking inferior technologies, putting them into our platform and large data sets and allowing them to maximize traffic and exposure to the right types of customers. It’s a harmonious win/win relationship.” In order to get the product to market, suppliers need to leverage the speed, performance, tech and reach of a distribution partner. No matter the industry, enhancing the tech of a partner (for free) will be a welcome opportunity.3. Pay attention to the dynamic aspects of your customer personas.Buyer personas are critical to understanding demand, and the science of personas is at the heart of creating successful customer experiences. “Savvy marketers recognize that one size does not fit all,” says Nelson. “Personas are fluid measurements of what a customer is thinking and doing as they try to solve a unique problem using your product. We attempt to time and stage every step of interaction — from inform and discover to shop and compare to buy and book. An individual customer may behave very differently when searching for business or leisure travel or several other reasons for travel. Good marketers understand this and create experiences accordingly.”By paying attention to your target audience’s shifts and trends, you can better adapt your technology and marketing plan to turn a searcher into a customer. Related: How AI Will Define The Future For The Hotel Industry4. Embrace machine learning. Machine learning has accelerated the speed of knowledge and market penetration. “The machine learning aspect has only made us smarter and faster in deciding where to place our bets and how to make best decisions with limited resources to make high-gains capital. It allows us to provide an efficient, targeted customer experience online or over the phone,” Nelson says. AI is here to stay, and it can help you make smart decisions when it comes to whether to invest in a technology.The travel industry is far from being down and out, but it is a poster child for early tech adoption. It is a trillion-dollar, global marketplace defined by agility, productivity and technology. Whatever your industry, your business can profit from the same methods to stay relevant, busy and ahead of your competition. 5 min read Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.last_img read more

Instagram Oculus WhatsApp and More Heres How Things Panned Out for 5

first_img Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. 9 min read October 22, 2018 Register Now »center_img This story was originally published on Sept. 27, 2018, and has been updated. The past eight months have been some of the most tumultuous in Facebook’s 14-year history.In March, the public learned of Facebook’s user data scandal and the now infamous Cambridge Analytica. The following month, CEO Mark Zuckerberg testified in a series of Congressional hearings. May marked reports that the FBI and Justice Department were investigating the social media giant, and weeks later, more alleged data-sharing partnerships came to light. In July, the company’s stock plummeted almost 20 percent after its quarterly earnings report, and an interview misstep by Zuckerberg — when he mentioned that Facebook wouldn’t necessarily remove content from Holocaust deniers — led to public outcry. By August, a score of prominent executives had left the company.But September marked one of the biggest blows to the social media giant: The co-founders of Instagram, the popular photo-sharing app said to be driving a significant portion of Facebook’s growth, announced their resignation. And today, less than a month later, Oculus co-founder Brendan Iribe announced he was leaving Facebook — reportedly due to differences in opinion over the future of Oculus.  Here are the stories of six founders who sold their companies to Zuckerberg.Kevin Systrom and Mike Krieger (Instagram)The backstory: When Kevin Systrom created one of the earliest iterations of Instagram, he had a wealth of experience — at a company that would later become Twitter, at a travel startup that sold to Facebook and at Google working in corporate development. It was early 2010, and the app — called Burbn — allowed users to check in to certain locations or post their plans. Instead, however, Systrom noticed they were sharing photos more than anything else. His co-founder Mike Krieger came aboard, and the two worked to create a social photo-sharing app. Instagram launched in October 2010, and less than two years later, Facebook shelled out $1 billion to call Instagram its own.The split: On Monday, Systrom and Krieger announced their resignation from Instagram and its parent company with a diplomatic statement. But reports point to rising tensions between the co-founders and Zuckerberg himself as key to their decision. Recently, Zuckerberg increased his involvement in Instagram’s day-to-day operations. What’s more, Systrom and Krieger reportedly clashed with Facebook over a range of decisions, including the latter’s pushback over the creation of IGTV for fear it would compete with Facebook Watch.The status: In their statement, Systrom and Kriger said they wanted to “explore [their] curiosity and creativity again.” As for what else is on their horizon? “Building new things requires that we step back, understand what inspires us and match that with what the world needs; that’s what we plan to do,” they wrote.Palmer Luckey (Oculus)The backstory: Oculus co-founder Palmer Luckey had a heavy hand in the rocket-like rise of virtual reality, thanks to a VR headset he built in his parents’ garage. The prototype’s Kickstarter campaign made waves with investors including Andreessen Horowitz and Founders Fund, even attracting Facebook, which paid $2 billion for Oculus in 2014.The split: Luckey stayed on as a Facebook employee until last year, when he and the company parted ways after reports said Luckey allegedly funded a pro-Trump troll group leading up to the 2016 presidential election. Zuckerberg maintains that politics did not factor into Facebook’s decision to end its relationship with Luckey.The status: At his new company, Anduril Industries, Luckey is working on a new system to detect unauthorized border crossings at the U.S. border. He aims to replace Trump’s idea for a physical wall with a digital one — an intelligent surveillance tool with virtual reality wrapped in — that’s always watching the country’s border. Luckey hopes to work with the Department of Homeland Security to implement the technology. Brendan Iribe (Oculus)The backstory: Brendan Iribe partnered with Palmer Luckey in 2012 to launch Oculus’s first Kickstarter campaign, which brought in about $2.4 million. He then took up the mantle as CEO after Facebook purchased the company and, in December 2016, stepped down to lead another arm of Oculus.The split: Iribe announced his impending departure from Facebook today. Although in a Facebook post Iribe mentioned he wanted to thank everyone who’s been a part of his journey, “especially Mark [Zuckerberg] for believing in this team and the future of VR and AR,” TechCrunch reports that Iribe and the Facebook executive team had “fundamentally different views on the future of Oculus that grew deeper over time.” The status: In his announcement, Iribe mentioned that this will be the first real break he’s taken in 20 years — and that he’s looking forward to recharging, reflecting and embarking on his next chapter. As for his thoughts on the future of Oculus? “This is our time to be pushing the state-of-the-art onward and upward,” Iribe wrote. “Every part of VR and AR needs to improve, especially the hardware and core technology, and Oculus has the best team in the world to do that. Although we’re still far from delivering the magical smart glasses we all dream about, now they are nearly within our reach.”Brian Acton (WhatsApp)The backstory: Brian Acton, the 44th employee at Yahoo, met Jan Koum in 1997, when Koum came to inspect the company’s advertising system. The two went on to become fast friends — and after they both left Yahoo 10 years later, Facebook rejected their job applications. When Apple launched the App Store, Koum went through a few iterations of the secure international texting app before almost throwing in the towel in 2009. Acton convinced him to stick with WhatsApp, and a few months later, he raised $250,000 in seed funding — earning him the title of co-founder, granted by Koum. Five years later, Facebook bought WhatsApp for close to $22 billion in a bombshell acquisition, paying about $55 per user.The split: When Acton left Facebook last year, he attributed the decision to his desire to focus on a nonprofit. But in March, the Cambridge Analytica scandal sparked Acton to write a bold message on Twitter:  “It is time. #deletefacebook.” It remains the most recent post on his Twitter page. (Koum, for his part, left Facebook in April.) Acton spoke publicly for the first time on Wednesday, telling Forbes that he and executives disagreed about the level of encryption necessary for WhatsApp — as well as Facebook’s desire to incorporate targeted ads and commercial messaging. He walked away from the social media giant in September 2017, deciding to leave as much as $850 million on the table in not-yet-vested stock.The status: Acton has invested $50 million in Signal, a messaging app he’s working with in order to essentially realize his original dream for WhatsApp: free, end-to-end encrypted calls and messages without ad partnerships. He’s also siphoned $1 billion from his Facebook earnings into philanthropy efforts serving healthcare in low-income areas and early childhood development.Jonathan Perlow (Beluga)The backstory: In 2011, three former Google employees launched Beluga, a group messaging service for Android and iOS that was designed for easy use with Facebook. One of them, Jonathan Perlow, made use of his past experience developing Gmail’s user interface. After Beluga went viral — and less than a year after its launch — Facebook acquired the company, hiring Perlow and his co-founders. The social media giant aimed to create a standalone messaging client, and Beluga would become the foundation for today’s Facebook Messenger.The split: Perlow left Facebook in June 2016 to start Trove Technologies, a full-service storage service that picks up, stores and returns items to customers. He co-founded the company with Michael Pao, Uber’s former head of product, and the two designed Trove’s online view of your own storage space, with items photographed, catalogued and available for delivery request.The status: Perlow’s roles at Trove mirrors the ones he held at Beluga: co-founder and chief technology officer (CTO). In 2017, Trove secured $8 million in funding.Nikita Bier (TBH)The backstory: Nikita Bier launched TBH, an app allowing users to send anonymous compliments to their friends, with three co-founders in the summer of 2017. He didn’t have high hopes — he had tried to launch as many as 14 apps in the past, and he knew the team would soon run out of funding. But within two days of TBH’s soft launch in a Georgia high school, about 40 percent of the original high school had downloaded the app — and it had spread to three other schools. In order to combat trolling, Bier made sure the app’s questions were structured in poll format — for example, “Who has the best laugh?” followed by the option to select one of four friends. By October 2017, Facebook had acquired TBH, reportedly for less than $100 million.The split: In July, Facebook announced it would shut down TBH due to “low usage.” The app reportedly had 5 million downloads at the time it was acquired, and the day after the deal went through, it ranked number one on the App Store’s daily download charts. But a little over a month later, TBH had fallen off the list of the top 500 daily downloads, which didn’t bode well for its future.The status: Bier told Business Insider that despite Facebook’s decision to discontinue the app, he would stay with the company and, as a product manager on the Youth team, continue to build new products alongside the former TBH team.

The new Dell XPS 13 2-in-1 for 2019 (starting at $999) takes everything we love about the regular XPS 13 — including an InfinityEdge display with close to zero bezels — and delivers up to 2.5 times the performance of its predecessor in a thinner design, thanks to Intel’s latest 10th-Gen processors.I had a chance to go hands-on with this convertible ahead of its launch, and it seems to have a near-perfect balance of sleek design, comfort and power. Here’s what you get for the money.AdvertisementDell XPS 13 2-in-1 price and availabilityDell says that the new XPS 13 2-in-1 will go on sale in July and start at $999, but that is for the Core i3 configuration with 4GB of RAM and a 256GB SSD. We’ll have to see how much the Core i5 and Core i7 models cost closer to availability.DesignWeighing 2.9 pounds and measuring 0.28 to 0.51 inches, the new XPS 13 2-in-1 is a bit heavier but thinner (2.7 pounds and 0.32 to 0.54 inches) than its predecessor. The new model includes a wider 16:10 screen with EyeSafe tech to reduce blue light, an edge-to-edge MagLev keyboard and a 19% larger touchpad. Similar to the regular XPS 13, Dell includes a tiny 2.25mm webcam near the top of the display to avoid a nose cam. But there’s another major design improvement: the lip up front makes it a lot easier to open this 2-in-1 with one hand.To keep things cool, Dell employs a dual-fan system and exhaust near the hinge.MORE: Best 2-in-1 Laptops – Laptop/Tablet Hybrids – Laptop MagSpecs: Intel 10th-gen processorsUnlike the previous XPS 13 2-in-1, which used weaker Y-series processors, the new model ups the ante with 10-nanometer U-series processors for more power. Plus, adaptive performance technology uses algorithms to give you the speed boost when you need it.The XPS 13 2-in-1 starts with the brand new Intel 10th Gen Ice Lake Core i3 processor, 4GB of RAM and a 256GB PCIe SSD, but you can get up to a Core i5 or i7 CPU and 8, 16 or 32GB of memory on board. You can also opt for a 512GB or 1TB SSD.DisplayBy default, Dell includes a 13.4-inch 1080p touch panel, but you can upgrade to a 4K display. The 16:10 aspect ratio gives you a 7 percent larger screen than the last XPS 13 2-in-1.Battery LifeDell promises up to 16 hours of battery life via the 51 WHr battery, but that’s based on its own testing. We want to put this system through our battery tests to see how it performs when surfing the web.Ports and PenDon’t expect much in the way of ports. You get just two Thunderbolt 3 ports, a microSD card reader and a 3.5mm headphone/mic jack. Dell also includes an active pen that magnetically attaches to the side of the system.OutlookOverall, the Dell XPS 13 2-in-1 looks like a big improvement over its predecessor and gives those looking for a laptop-tablet combo a nice-looking alternative to the regular XPS 13. But the 2-in-1 competition has gotten a lot better since Dell debuted the original XPS 13 2-in-1 in 2017. Can this new convertible catch up to the likes of the HP Spectre x360 13 and Lenovo Yoga C930?

Firefox 540 find out what is new

first_imgFirefox 54.0: find out what is new by Martin Brinkmann on June 13, 2017 in Firefox – Last Update: June 30, 2017 – 75 commentsFirefox 54.0 has been released on June 13, 2017 to the stable channel. The new version is offered through the Firefox web browser’s automatic update functionality, and also provided as a direct download from Mozilla’s website.All other Firefox channels, those are Beta, Nightly and ESR, are also updated. Mozilla did remove the Aurora channel from the release cycle when Firefox 53 was released.Firefox Beta is promoted to version 55, Firefox Nightly to version 56, and Firefox ESR to version 52.2Executive SummaryMozilla enabled multiple content processes for Firefox’s multi-process architecture for the majority of eligible systems. The number has been raised from 1 to 4 content processes.You can check out the Firefox 54.0 preferences changes here.Firefox 54.0 download and updateFirefox Stable is configured by default to check for updates automatically. The browser’s automatic update feature will pick up the Firefox 54.0 update automatically, download it, and install it on most Firefox systems.The update check is not in realtime, but you may run it at any time manually in the following way:Tap on the Alt-key on the keyboard, and select Help > About Firefox from the menu.Firefox queries Mozilla’s servers for update information. Depending on how the browser is configured, if an update is found it may be downloaded and installed directly, or on user request.Direct download links for Firefox installation files:Firefox Stable downloadFirefox Beta downloadNightly downloadFirefox ESR downloadFirefox unbranded builds informationFirefox 54.0 ChangesSupport for multiple content processesThe big new feature of Firefox 54.0 is support for multiple content processes. Firefox’s multi-process architecture has been integrated in previous versions of the Firefox browser, but up until now with only one content process.What this means is that all websites and services open in Firefox at any time use the same content process. Still good in terms of reliability of the browser as the browser ui is running in a separate process, but not as good as separating these into multiple content processes.Chrome for instance uses one process per site. Firefox won’t do that, and the main reason why is that it impacts performance and memory use too much.Mozilla picked four content processes as the default for the switch. So, once Firefox is updated to 54, the bulk of Firefox installations with multi-process enabled, will use four content processes instead of just one.Firefox users may set the number of content processes manually (read all there is to know about multi-process Firefox in our guide)Type about:config in the Firefox address bar.Find dom.ipc.processCount.Double-click the preference, and change its value to a positive integer.

Guides by Lonely Planet for Android

first_imgGuides by Lonely Planet for Android by Martin Brinkmann on August 22, 2017 in Google Android – 6 commentsGuides by Lonely Planet is a free application for Google Android that provides you with free city guides curated by Lonely Planet.It takes at least some preparation to visit a different city in your own country or another country. This ranges from figuring out how to get there and where to stay, but also what you may want to see and do once you are there.Traditional travel guides are more and more replaced by online solutions, and one of the solutions is Guides by Lonely Planet for Android.Guides by Lonely Planet for AndroidThe free application lists all available cities in its interface on launch. The list is quite large and features popular destinations such as Moscow, Amsterdam, Barcelona, and New York.A search is provided to find cities quickly, and you may also filter by region to reduce the number of items in the listing.You may add as many cities as you like, and get among other things offline access to maps for that city.The city hub starts with a map at the top that lists major points of interest that editors added to the map. You can filter this by “see”, “eat”, “sleep” and “shop”, “drink” or “play”, or use the built-in search to find places, themes or categories.If you are interested in flea markets for instance, you may use the search to find all of those markets easily without having to go through the “all” or “shop” listings.You can zoom in and out of the map, and tap on any of the dots displayed to check it out in detail. The name of the place and its type is displayed when you do so, and you may click on the link that is provided to open a page full of information on that particular place.Information usually includes a description, location and contact information, how to get there by public transport, entrance fee information, and places of interest that are nearby.When you switch from the “all” listing to another listing, you get more places that fit the selected category. The “see” category is special as you get photos of the places, whereas you only get text listings if you pick one of the other categories.The “all” category usually offers a curated collection that lists must see places on top of that.A tap on the menu icon display links to the “need to know” and “my favorites” section of the city you have selected. There is also a “phrasebook” link for select languages.You may add places to your favorites, and list all of your favorites using the “my favorites” listing.The “need to know” section is quite useful. It gives you an overview of the city, provides information on transport, and makes suggestions based on your budget.Transport offers information on how to get to the city from the airport or main station, using public transport, as well as car and taxi. A public transit map is provided for each city as well which may come in handy.Phrasebook finally is offered for places in Spain, France, China or Japan. It lists top phrases, and phrases based on certain conversation topics such as eating & drinking, shopping or sightseeing. Only the basic phrases are freely available. You can unlock all 19 supported languages for a one-time purchase price of €5.99.Closing WordsGuides by Lonely Planet is an excellent application for Android. You may add as many cities as you like and gain offline access to important information right away. The map lacks a bit in my opinion; favorites are not highlighted on it, and you don’t get comfortable options such as getting directions or additional details when you tap on a point of interest.All in all though it is well produced, and the additional information you get is well worth the download.Now You: Do you use travel apps?Summary12345 Author Rating5 based on 1 votes Software Name Guides by Lonely PlanetOperating System AndroidSoftware Category AppsLanding Page https://play.google.com/store/apps/details?id=com.lonelyplanet.guides&hl=en Advertisementlast_img read more
