first_imgPakistan’s coach Younis quits ISLAMABAD (AP): Waqar Younis has quit as Pakistan coach only a day after Shahid Afridi stepped down as Twenty20 captain. Pakistan lost three group matches at the World Twenty20 and made an early exit from the tournament in India. Younis, who was national coach for 19 months, says “unfortunately I couldn’t give the result which the nation was expecting.” Younis had three months before his contract with the PCB was due to expire, but he quit after meeting with the Pakistan Cricket Board officials in Lahore on Monday. Setback for WCup stadium MOSCOW (AP): The official completion date of Sochi’s stadium for the 2018 World Cup has slipped back five months to November, the second such delay for a Russian World Cup venue in the last week. Regional sports minister Lyudmila Chernova announced the delay in comments to the state-run Tass agency, but did not give any explanations. The Fisht stadium hosted the opening and closing ceremonies for the 2014 Winter Olympics, but has needed lengthy construction work to convert it for football and expand its capacity to over 47,000. Last Friday, Russian Sports Minister Vitaly Mutko said the St Petersburg stadium had fallen three months behind schedule but would still open by the end of the year. Sammy Stadium CASTRIES, St Lucia (CMC): West Indies T20 cricket captain Darren Sammy yesterday expressed his delight at the decision of the St Lucia government to rename the Beausejour Cricket Ground, after him following the exploits of the regional team in the just-concluded T20 World Cup in India. Sammy, along with fellow St Lucian, Johnson Charles, returned to a hero’s welcome at the Hewanorra International Airport, where they were greeted by Prime Minister Dr Kenny Anthony and other St Lucians. “Big-time reception, homecoming,” Charles said in a video posted on Facebook, while Sammy said Anthony had announced that the island’s premier cricketing ground will now be known as the Darren Sammy National Cricket Stadium. “To God be the glory,” Sammy said, adding “I am truly honoured, I am humbled and bless. Thank you, we always know St Lucians love their own and the love and respect and admiration I have just received at the airport, oh my God, thank you very much.” Giorgi turns down Italy call-up ROME (AP): Camila Giorgi has turned down a call-up to Italy’s Fed Cup team for its World Group playoff against Spain, choosing to compete in qualifying for a tournament in Stuttgart, Germany, instead. The 48th-ranked Giorgi announced last week that she was cutting off ties with the Italian Tennis Federation – apparently because the federation insisted she play Fed Cup. Italy captain Corrado Barazzutti called her up anyhow for the April 16-17 series. Giorgi had until Monday to confirm her call-up and the federation announced yesterday that 72nd-ranked Karin Knapp was taking Giorgi’s place on the team, which also includes Roberta Vinci, Sara Errani and Francesca Schiavone. Giorgi is currently playing in Katowice, Poland, where she beat Aliaksandra Sasnovich of Belarus 6-4, 6-4 in the first round yesterday.last_img read more

first_imgGLENSWILLY came oh so close to an incredible Ulster title at Healy Park in Omagh today.The Co Donegal champions took on the Derry champions Ballinderry in the showpiece final.Despite an incredible comeback – and a man of the match performance by talisman Michael Murphy – Glenswilly just found Ballinderry too hot to handle. The Glen men had gone into a stunning lead, with Murphy finding the net in the first seconds of the game.But Ballinderry clawed back, scored their own goal and went in half-time leading by four points 1-06 to 1-02.Murphy and Glenswilly came storming back at the start of the second half, this time Murphy providing a goal for Caolan Kelly.Ballinderry however came back again and scored a series of wonderful points from play, with Murphy trying to keep Glenswilly in touch with some great scores. But it wasn’t to be. Ballinderry won 1-13 to 2-06.The Glen men gave it their all – and can travel home to Donegal this evening with their heads held high. HEARTACHE AS BRAVE GLENSWILLY LOSE ULSTER CLUB FINAL was last modified: December 2nd, 2013 by John2Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window) Tags:AIB Ulster FinalBallinderryglenswillylast_img read more

SA business gets tech-savvy

first_imgRELATED ARTICLES • SA internet use passes 5m mark• SA web users to double by 2014• Broadband boost as Eassy hits SA• Student boffin is top programmer• Talk 11 languages on your phone MEDIA CONTACTS • Arthur Goldstuck MD, World Wide Worx +27 11 782 7003 [email protected] • Christa Botha Corporate Communications Research In Motion +27 82 562 5264 [email protected] have made a dramatic entry into corporate South Africa, far surpassing general consumer use or small business use.This is a surprise finding from a new research study released today by World Wide Worx. The Mobile Corporation in South Africa 2010 report reveals that three-quarters of South African companies have deployed smartphones in their organisations, compared to almost none two years ago.The study, backed by First National Bank and Research In Motion (RIM), shows that saturation point has almost been reached by large South African companies in the use of fixed landlines (96%) and ordinary cellphones (92%). And, as forecast in 2007, 3G data card penetration has also reached near saturation, with 94% of large companies deploying it. Now the focus has turned to integration of smartphones with business processes.“These results show that enterprise mobility solutions are no longer just nice to have,” says Deon Liebenberg, RIM’s regional director for sub-Saharan Africa. “They’re essential for businesses that want to be competitive, responsive and efficient in a world where a customer won’t wait for a salesperson who is visiting customers and where project flow can’t stop because a manager is at a full-day meeting.“Not only does mobility allow companies to improve internal efficiencies and communications, it also enables them to interact more effectively with their increasingly mobile customers.”The study also showed that corporate South Africa expects to embrace the new world of online services to an extent that was not even anticipated as recently as one year ago.“Until last year, concepts like software as a service (Saas) and cloud computing were regarded as little more than buzzwords,” says Arthur Goldstuck, MD of World Wide Worx.Yet, in the next 24 months, 84% of South African corporations expect to have a Saas strategy in place, and 60% expect to have adopted a cloud computing strategy.“These aren’t technologies as such,” says Goldstuck. “They are strategies that make the organisation’s use of new technology more efficient. From storage systems to software deployment, from hardware upgrades to network capacity to bandwidth, the focus is on cost-effectiveness, flexibility and mobility.”Among the technologies expected to take off as a result of the Saas and cloud computing revolution are:Fixed-mobile convergence, with 72% of companies expecting to adopt systems that allow seamless connectivity between fixed and mobile networks.Virtualisation, with 65% expected to embrace this flexible and cost-effective approach to network and server technology.Outsourced storage and archiving systems, with half of large South African companies predicting they will be using it in the next 24 months.The combined effect of these technologies is that, while the organisation’s buildings and infrastructure may still be confined to a specific site, its people, activities, information, documentation and data have been freed from location.“We are literally seeing the foundations being laid for the company of the future,” says Goldstuck.Liebenberg adds: “Smartphones are now mainstream devices within South African businesses, but the smartphone revolution has only just begun. Enterprises should now be looking at what smartphones mean for their businesses in a more strategic and holistic fashion. They need to work towards mobilising their core internal and customer-facing processes so that their employees can use ubiquitous connectivity to be productive and responsive wherever they are.”The Mobile Corporation in South Africa 2010 forms part of the Mobility 2009 project, which included research among 1 000 consumers, 1 000 small and medium enterprisese and 240 large enterprises in South Africa.last_img read more

OCF Young Cattlemen’s Conference provides industry learning experience

first_imgShare Facebook Twitter Google + LinkedIn Pinterest The 2019 Ohio Cattlemen’s Foundation Young Cattlemen’s Conference (YCC) hosted 19 cattlemen and women for a three-day leadership development program in central Ohio, Aug. 8-10. The conference was made possible through the support of program sponsors, Farm Credit Mid-America, Ohio Beef Council, Ohio Corn & Wheat Growers Association, Ohio Soybean Council and the Rick Malir & Bonnie Coley-Malir Beef Leadership Fund.YCC kicked off Thursday evening at the Ronald McDonald House of Columbus where participants were able to tour the house and learn about its mission. Attendees also had the opportunity to network over a beef dinner with members of the Ohio Cattlemen’s Association’s Board of Directors, program sponsor representatives and other industry professionals. Vice President of Wendy’s Protein Procurement and Innovation, Quality Supply Chain Co-op, Inc. (QSSC), Dr. Henry Zerby, served as the guest speaker for the evening and shared his thoughts on the future of the beef industry and some of the challenges it faces moving forward.On day two of YCC, conference attendees participated in a mini-Beef 509 session with Dr. Lyda Garcia, assistant professor of meat science for The Ohio State University’s Department of Animal Sciences. This hands-on experience included learning how meat is graded, the fabrication of wholesale and retail cuts, and other issues that can impact beef quality and pricing. Participants also viewed the champion beef carcasses from the 2019 Ohio State Fair and visited The Ohio State University’s football practice facilities.Ohio Cattlemen’s Association (OCA) staff then discussed the value of membership and the role OCA has in legislative and regulatory issues; participants also heard from Executive Director of Government Affairs for the National Cattlemen’s Beef Association (NCBA), Allison Rivera, about the latest federal issues impacting the cattle industry. The afternoon was spent at the Ohio Statehouse where participants met with Representative Darrell Kick (District 70). Representative Kick, who sits on the House Agricultural and Rural Development Committee, spoke about current Ohio legislation affecting the beef cattle industry and answered questions from the group.That evening, participants were hosted at the home of program sponsor, Rick Malir and Bonnie Coley-Malir. While there, attendees were able to network with one another and learn more about the couple’s agricultural roots and their passion for the beef industry and professional development.The final day of the conference was kicked off by Ohio Beef Council (OBC) staff, with a discussion regarding OBC’s role in checkoff collection and beef promotional efforts in Ohio. Attendees also participated in a spokesperson training program coordinated by Director of Grassroots Advocacy and Spokesperson Development for NCBA, Ryan Goodman. Goodman led participants through a media training session that strengthened their communication skills, encouraged attendees to tell their beef production story and helped them become more effective cattle industry leaders.The purpose of YCC is to offer emerging Ohio beef industry leaders and young producers the opportunity to build their own leadership skills as they network with beef industry leaders, government officials, businesses and media. Young beef producers interested in attending the 2020 conference should contact the Ohio Cattlemen’s Foundation at 614-873-6736 or email [email protected]last_img read more

Six Reasons to Stick with Your Startup: Survival Stories from the Trenches

first_imgTags:#start#startups Starting a new tech company is a labor of love. Particularly in the beginning, when funds are low, expectations are high, and the product is still a twinkle in the developer’s eye, stressful situations under external pressures can lead to pull-the-plug moments.When we interviewed Pandora founder Tim Westergren last week, he shared his personal brush with startup death: In 2007, it seemed that the music-streaming site would have to declare bankruptcy and close shop. Pandora’s success is one reason to stick with your own startup. Here are six more.Quick Growth Is a Good Thing, Right?In the heat of SXSWi 2009, Twitter users started snarking that Twitpic was down. The service had grown exponentially in the month or two before the geekfest, and founder Noah Everett said the sudden spike in adoption and use caught him completely off-guard.During that month, the one-man-show known as Twitpic “was barely usable and breaking all the time; and as you know, users on Twitter are very vocal about something when its not working,” said Everett via email.“The decision I had to make was to either shut the site down – since it was basically broke – or suck it up and fix it as fast as possible. I locked myself in my apartment for two weeks straight. I turned off the phone, Twitter, email. And I recoded the site and put together a scalable hardware platform to run Twitpic on. It worked and took two weeks less time than it should have.”You Don’t Touch a Man’s WheelsBootstrapper Tom Blue, who founded Lead411 in 2001, wrote us to tell about the time this cardinal rule was broken.“I am sitting in my office and I hear my car alarm go off. I run out to the parking lot to see my car driven off by the repo man. Sad, but true.”Blue said he convinced the bank to return the car and got family to loan him some money. But the process was costly and a huge waste of time. “After that moment, I realized that mentality is stupid. I should only focus on what is productive. I streamlined my focus on what was important – and at the bare minimum, cash flow is important.”From the depths of financial catastrophe, Blue persevered, and his startup saw staff grew and revenues tripled in 2004 and doubled again in 2005. Ultimately, wrote Blue, “It was actually one of the best lessons I have learned.”The Mundane DetailsEntrepreneur John Sarvay emailed us to share his own story. “I’m discovering that there are a couple of different scary startup moments – the dramatic cliffhangers (new company teetering on the brink; new company meets sexy venture capitalist; new company takes off) I think are dwarfed by the mundane (waking up every day wondering if there’s enough cash in the bank).“Nine months into my own startup, I’ve discovered a nice middle ground.”But that comfortable middle ground was nowhere in sight when Sarvay woke up the morning after his startup’s launch party with a severe case of entrepreneur’s remorse.“I realized I’d spent more on the launch party than all of my other business marketing. In the first three months of 2009, I brought in three percent of what I earned the previous year. The economy was continuing to melt down. I was insane thinking I should launch a business on my own.“That lasted three days.”Little by little, cash started flowing in. By this May, Sarvay wrote, “We had enough cash flow to actually pay our bills for the month – both for the business and for our household. Going into July, we have enough to pay those bills for three months.”“This whole startup process has been simultaneously terrifying, stupid, exhausting, exhilarating, and validating. It’s the smartest thing I’ve ever done. If I’d done it three years ago, I’d have failed. I might still fail. But I don’t regret one second of it.”Surviving the First BubbleCEO Brian Williams wrote us about his startup’s survival, not just through recent financial storms, but through the first dotcom crash, as well.“We started Viget in late 1999 with a few funded startups as clients, no funding ourselves (bootstrapped), and a lot of reason for optimism. Within a year, the dotcom era imploded, our clients had lost their funding, and it was no longer cool to be a consultancy run by 20-somethings. We were barely making payroll and considered throwing in the towel.”But instead of quitting, the team made one last effort, pitching to one of the few surviving startups in that time. “We were sweating bullets as we waited to hear back from them…Happily enough, they liked our proposal and hired us. I still remember coming up with some reason why we were going to be in their neighborhood that afternoon and could pick up the retainer check then instead of waiting until the kickoff meeting. I didn’t mention that we needed it to make payroll.”Williams notes his company is now 40 staffers strong and still working with startups. And since that dotcom bust, he wrote, “We’ve never missed payroll, never had layoffs. And although it has indeed been (and continues to be) a lot of hard work, I’ll always be thankful that we decided to stick it out.”Thirty-Seven Cents and a Heart Full of Hope AdrenalineGrocio founder Gerald Buckley went so far as to share the exact dollar amount of his worst fears realized:“I was $0.37 away from closing it up. Literally, that was all I had left in the bank account. There wasn’t enough to pay next month’s legal bills.”However, a dramatic turn of events saved him and his startup at the last minute. “In mid-November, Grocio won top prize in a local business model competition sponsored by the City of Tulsa and a local bank. That put $30K in the bank (non-equity, non-debt). Then the state of Oklahoma awarded us $100K matching funds (again, non-equity, non-debt). Money became less an issue and allowed us to focus on execution.”Although the economy began changing the equation once again last fall, Buckley encourages other startups, “I’m going to have the startup bug all my life, I think. NEVER give up if you really believe!”When Worse Comes to WorstHowever, we’d be a bunch of cockeyed optimists if we didn’t admit that sometimes, even the best teams and the best ideas can fail.Serial startup techie Dan Bedford wrote us to share a story of lessons learned the hard way. “In the summer of 2005, I was starting up an internet video platform. We had dreams and aspirations of being this all-encompassing entity… The technology was decent, and it had potential.”The company started getting some interest from angels, and the staff got excited. Until one of the investors started bringing his own staffing picks into executive positions, that is.“This is where is started to get fishy. A lot of money was being funneled to these people he hired… The company was bleeding money to a select few individuals who put not an ounce of their blood, sweat, and tears into the company.”During this time, the stock market crash began to unfold. Not so slowly, investors backed away. “We were left out to dry, and dry we did,” wrote Bedford. “Jobs were cut down to the core, and not too long after that, we had to close our doors.”But Bedford, who is still working in the tech startup space, refuses to let one closure set his course. “I don’t dwell on the negatives of the experience. Learning from the negatives and applying it to something positive is the way to go with this kind of business, I have found.”As many startups can attest, it takes a whole lot of failure to break through the barriers to success. In the words of one tireless innovator, “I have not failed. I’ve just found 10,000 ways that won’t work.”And, as Bedford wrote, “Any experience with startups is a good experience.“You always have to evolve with the environment because it’s constantly changing all the time. That’s not something you can get in an established corporation; all those protocols have been worked out before you came and are now set in stone. It’s the involvement in building something new that true entrepreneurs are addicted to.

Facebook Suspends Phone & Address Sharing Feature

first_imgmike melanson Related Posts Why Tech Companies Need Simpler Terms of Servic… Just before the weekend, Facebook announced that it would begin allowing third-party applications and websites to request that users share both their mobile phone number and address. Now, the company has said that it will be putting the new feature on hold while it makes changes to make sure that Facebook users are aware of the potential for data sharing.Douglas Purdy, director of developer relations, just posted on the Facebook developer blog to explain that Facebook agrees with its critics that the feature could be better implemented and the company will be pulling it until changes are made.“Over the weekend, we got some useful feedback that we could make people more clearly aware of when they are granting access to this data. We agree, and we are making changes to help ensure you only share this information when you intend to do so. We’ll be working to launch these updates as soon as possible, and will be temporarily disabling this feature until those changes are ready. We look forward to re-enabling this improved feature in the next few weeks.”Purdy was just hired last November to “improve Facebook’s relationship with the community.” This move will not only help with Facebook’s developer community, but potentially its user community too. A primary complaint of many commenters, developers and members of the data portability community was that the permissions dialog design did little to convey to users that they were now sharing information that had previously been kept for use on Facebook, not third-party applications.

Purdy was not specific in what changes would be made, but we hope that it has to do with at very least the design of the dialog, if not even allowing users to have granular control over what they share with who at the time of sharing, not in a separate settings page.For an in-depth look at the new feature, give “Facebook & Identity: The Continued Push Toward Becoming Your One True Login” a read. 8 Best WordPress Hosting Solutions on the Marketlast_img read more

The European Parliament’s Zero-Energy Ambitions

first_imgThe European Parliament votes to impose a zero-energy standard on new buildings beginning in 2019As they do in the U.S., residential and commercial buildings account for an estimated 40% of energy use in Europe. Legislative initiatives to reduce or eliminate net energy consumption by buildings, however, are progressing a bit more aggressively on the other side of the Atlantic.Last week, for example, the European Parliament voted 10-1 to require that new buildings constructed after 2018 produce their own energy.The parliament also demanded that the European Commission – the European Union’s executive branch, on whose legislative proposals the parliament and the Council of the European Union vote – implement two national financing strategies by 2014, one that would offer value-added tax reductions on insulation materials, and one that would create an energy efficiency fund to support private and public investment in buildings.Reshaping an existing strategyThe MEP (Member of the European Parliament) vote actually is aimed at revising, with its stricter standards for overall efficiency, the European Union’s 2002 Energy Performance Buildings Directive, whose goals are to develop a common methodology for calculating the integrated energy performance of buildings; develop minimum standards on the energy performance of new buildings and existing buildings that are subject to major renovation; develop systems for the energy certification of new and existing buildings; and establish regular inspection of boilers and central air-conditioning systems in buildings, and an assessment of heating installations in which the boilers are more than 15 years old.The MEPs also want the EC to establish the energy-efficiency calculation methodology by 2010, and to apply minimum national energy efficiency standards to all buildings in Europe under major renovation. Existing requirements, adopted last November, apply only to buildings over 1,000 square meters.As a press release from environmental news service ENDS Europe noted, the MEP vote and recommendations were welcomed by the European Alliance of Companies for Energy Efficiency in Buildings (EuroAce), an association of 20 companies working with the EU on building efficiency issues.“This is a good day for energy efficiency … a striking endorsement from the European Parliament,” EuroACE senior advisor Andrew Warren said in press release. “All the major parties voted overwhelmingly in favor. The European Parliament is to be congratulated for enabling the Swedish Presidency to the EU to now achieve its stated goal of getting full agreement on the proposal before the end of 2009.”Eurima, an association of insulation manufacturers, offered a similarly positive response to the vote. Calling the amendment appropriately “ambitious,” the group, in a press release, praised the MEPs for tapping into the building sector’s “vast potential to deliver energy efficiency, as well as providing a strong stimulus towards economic recovery.”Two other groups focused on energy efficiency – the nonprofit European Council for an Energy Efficient Economy, based in Stockholm, and the European Renewable Energy Council – also endorsed the European Parliament vote, saying it rises to the challenge posed by climate change and will, in the long run, make EU members more economically competitive.last_img read more

Why Does Green Building Matter? (Part 2) – Building Science Podcast

first_img_This podcast series is excerpted from a two-day class called “Building Science Fundamentals” taught by Dr. Joe Lstiburek and Dr. John Straube, of Building Science Corporation._For information on attending a live class, go to BuildingScienceSeminars.comIn our last episode, Dr. John discussed how, in the middle of the 20th century, cheap energy allowed us to build wasteful buildings. In this show, he explains how improving energy efficiency in buildings is the most affordable way to address global energy and climate concerns. He also lists his core green building strategies.__________________________________________________This seminar is not about how to produce cheap, clean energy, but it is about how to save energy. And one of the reasons it’s about saving energy is that’s the lowest-cost, lowest environmental impact approach to solving the energy security climate change problem. There’s not much argument about that by anyone who’s putting numbers to it, but it’s a lot easier and sexier to buy a photovoltaic panel and throw it on the roof. But often the least sexy and harder approach is the best one.Buildings should already be better than they areThe International Panel on Climate Change—the people who give you dire predictions on how the water levels are rising—also have done a report on what could we do as a society on the planet to reduce CO2 emissions and what it would cost. They looked at all of these categories, including buildings, and said, “So, what would it cost at $20 a ton—how many tons of CO2 could we save at $20 a ton?” No matter what price you put on carbon, buildings are the biggest form of saving CO2 emissions. So you could reduce human output of CO2 on the planet by 20% for a cost of less than $20 a ton just by doing buildings. The other thing about buildings is that they’re the lowest-cost way of reducing CO2. If you want to reduce CO2 by having more fuel-efficient cars, it’s going to cost more. In fact, even at really expensive levels, it’s hard to reduce emissions of CO2 in the transportation sector. You can do it in the agriculture sector, but you can’t do it in the transportation sector. Buildings, on the other hand, at the lowest-cost increment, will save the most amount of CO2. One of the lines that I liked out of this study that the Economist magazine also repeated and quoted is that when they looked at it, buildings appear to be currently irrationally designed, and economically they should already use less energy than they do—with no carbon tax at all—and that’s absolutely what we see when we look at our building designs. And it’s like, well, but that doesn’t even make sense today, with gas at 11 dollars a therm and electricity at 10 or 12 cents a kilowatt hour—and yet we continue to do it. It’s mostly a disconnect of what can be done at what cost to reach what end.Some people understand the value of energy efficiencyAnother Chevron ad here is saying the good news is that we’ve got a huge source of alternative energy; it’s called conservation. Does anyone find it interesting that one of America’s largest oil companies is putting in ads in major newspapers saying you should save—don’t waste—save oil? You think maybe they know something that we don’t? We have actually had tremendous progress in industry in reducing energy consumption for output. We already have the energy content of all of our industrial output. In the same time period, Japan has reduced the energy content of its economy by a factor of 4. One of the reasons that Japan doesn’t care too much about energy prices going up, especially oil, is that they’re using less oil every year. Per GDP output, they don’t use much oil, so it doesn’t impact their lives that much. If you’re in England and you’re paying 7 dollars and 50 cents a gallon, the fact that the price goes up 50 cents a gallon, well, it’s not really noticed much. When you’re paying 3 bucks and it goes up 50 cents, you actually notice. So, a lot of countries are much better equipped to handle these increases in energy costs than is America. Countries that are least able to handle it are always the same: the poor ones in sub-Saharan Africa, and Bangladesh. They’re the ones that are actually being hit the hardest. Now, Royal Dutch Shell is the second-largest privately held oil company in the world, and recently they’ve been rattling the chain as well. This is from a letter to the editor of the London Times saying efforts to fight global warming will be wasted unless we concentrate on energy efficiency. Again, second-largest oil company on the planet, writing letters to the editor saying you’ve got to focus on energy efficiency. I think this is unbelievable, and no one seems to be paying attention—that this is a huge shift in mentality on the energy-supply side, huge.A lot of room for improvementWhat we do notice is the price of gas going up, and they’re connected. So basically, easy oil is done. If we switch to coal, we cause more of a CO2 problem. So the easiest, lowest-cost, biggest-impact thing we can do now is stop being stupid—meaning, stop the waste. Ninety-five percent of all the energy that enters the American economy is wasted; 95%. Now, we’re doing better than that here, because you can notice that these lights here are incandescent bulbs, and therefore they’re about less than 2% efficient at converting electricity into light. If you look at the typical mix of America’s energy electricity production, it’s about 30% efficient; so, 30% efficient times 2% efficient—yeah, it’s about 0.7% efficiency. So, from coal to light, 0.7% efficiency. Wow, that sucks doesn’t it? Now, in this particular example, we could multiply that by 5 by replacing the fryer bulbs that are keeping us warm and keeping the air conditioner running, with compact fluorescents, and that would make economic sense the day they were installed, because the moment that this thing with a 2000-hour life had to be replaced, the labor cost of that first replacement pays for the whole CFL. Forget energy. It’s got nothing to do with energy. Just the replacement and labor costs. But do we have incandescent bulbs in here? Yep. Why? Cause…what is the answer? Cause we’re stupid. I can’t really think of any other explanation as to why we would be putting incandescent floodlights that we then cover half the light output on and bounce off a dark-colored surface—because if we actually looked at the efficiency of lighting the table, that .7% number I just calculated? Probably cut it in half again. So when you look across the economy and you look at all kinds of processes and things that we do, 95% is an optimistic number that we throw…we’re 5% efficient. And it’s pretty easy to be 20% efficient. That’s a lot of room to move; that’s the good news. The good news is that we actually can solve the problem. The bad news is that we really haven’t been doing anything.Not all green buildings are sustainableHow does this connect to green buildings? Well, first of all, green buildings recognize that there’s an issue going on here. There’s a whole bunch of agendas that are being satisfied by a green-building label, but a sustainable building or sustainable society is one that can be sustained or continued to be produced for the long term without adversely affecting the conditions necessary to support the same activities in the future. That’s a real definition. Green we can argue about; sustainable, it’s right in the dictionary. We know what it means. And we’re nowhere near building sustainable buildings. When I hear that term, it’s like, “My god, are we going to dilute that brand as well?” The green brand has already being diluted, and a lot of people are skeptical. But don’t screw up what is actually a well-defined term called sustainable and say, “I’m making a sustainable building.” No, I’m building a more sustainable building. My building is net-zero energy or something like that, but it sure ain’t sustainable. But what we could do is minimize nonrenewable energy and resource use, and that might be a greener building than our current buildings. Who knows? What we do know is that green buildings are durable, because if they last twice as long, they use half as many resources over their life. Pretty simple. That’s an easy one. But, of course, to be able to be used for 50 years they also have to be functional. If you don’t design a building that is able to be functional, what’s the sense of having it in the first place? And, of course, that’s where the beautiful comes in, too. People will look after and want to use it.So, how does this connect to green buildings? Well, building science is the science of making buildings that work. It’s not in the dictionary, because if you look up building science in the dictionary, you won’t find an entry since building science really isn’t that common. But our definition is making buildings that work. And green buildings are buildings that work better than normal. They work well. They’re more durable, they’re more energy efficient, they’re more comfortable, they’re more healthy. They just do a good job of being a building. The confluence of those things is where building science lies on the green side. The normal kind of building work that we do that isn’t green is concerned about energy and comfort and rot and mold and corrosion and not getting sued and being cheap to build and not burning down. But there’s a huge overlap with the green side of reducing energy consumption, making a durable building, using materials that are sensible. And the building science is, in essence, inextricably connected to the green buildings.Several steps to building greenHere are my strategies for green buildings. We tried to put them all on a slide, which of course is impossible, but… first of all is keep it simple and keep it small. Well, that would be pretty easy. By simple we mean compact shape ideally, but we also mean keep it simple so that’s there’s not too many widgets, gadgets, and things that can go wrong and break down. And oriented, respecting the sun and wind and rain. Then reduce your heat loss and gain, which means lots of insulation and avoiding thermal bridges; use very good windows; make a building airtight and then ventilate to the appropriate level. Then we avoid energy use by using efficient appliances. And always remember the most efficient appliance is one that’s turned off.There’s probably a little over an average power plant being used right now in America, total, to light stairwells where no one is. So even if I put fluorescent bulbs in every stairwell where no one is in America, that’s not very efficient because no one’s there. It’s 0% efficiency by definition. You have to be able to turn things off when no one’s around. Fans have to be turned off, lights have to be turned off, etc. We use daylighting and motion sensors to achieve that. It’s not just about getting a premium-efficiency motor, it’s having a control system that turns it off; because the most efficient thing is, one, turn off the control, guys, right? So then we have durability—and drains, airtight, and drying are what I put down as durable (and we’re going to talk a lot about that aspect throughout this seminar), and then and only then do we generate renewable energy. It makes no sense to put on photovoltaics or even solar hot water until you’ve done all of these things. And small wind turbines—the ones that are this big around—make less sense than even photovoltaics because the physics require that they be large. You might have noticed that most commercial wind turbine projects use really big, large turbines because that makes them efficient, and efficient means they are less costly. Now, efficient makes them greener, right? Fewer materials used for electricity generated. A whole bunch of little 8-ft.-diameter wind turbines is actually not very green. You’re better off pooling your resources and getting big wind turbines. That’s a much greener and economic and sensible thing. It’s also more economical to put lots of insulation in.Tighter buildings are still cheaper than solar panelsSo, the basic strategies are always you start off with building shape and orientation, which costs nothing except design effort at the napkin stage. As soon as you reduce energy consumption in a building dramatically, it makes sense to use renewables. Right now, we would say that electricity from photovoltaics in Massachusetts—no subsidies or anything like that—costs around 50 cents a kilowatt hour. That’s expensive. On the other hand if you were to reduce your energy use by a factor of 3, your total energy bill wouldn’t change from what you already pay, because even though the cost per kilowatt hour is high, you use a lot less kilowatt hours. And those two things have been converging for some time, by the way. Normal electricity costs have been going up, renewables have been coming down, and people have been able to figure out how to use a lot less electricity. So it makes some sense to keep your electrical bill—you could actually keep your electrical bill the same and use photovoltaics if you really went far enough. We’re not quite there, but we’re close; with subsidies, we are there.When renewable energy makes economic senseNow, given the existing stock of buildings, we’re going to have to retrofit a lot, and that gives us opportunities to do renewable energy and to reduce the loads dramatically. This is a plot showing 15% per annum growth in renewable energy. I’ll let you know that photovoltaics and wind power have been growing more than 20% to 30% per year. So, the growth rates for the last five or seven years have been well higher than 15% per year. And that compound interest means they could produce a significant chunk of the electricity that’s needed in this country. But at the same time we have to reduce the energy consumption of our buildings. So, the energy consumption typically grows at around 3% per annum—2% to 3% per annum—and has for the last while, and that’s the red line. What we have to do is build in efficiency gains of around 4% per year, and then the two things will converge in 25 years. Renewable energy can provide a majority of the energy required by our buildings if both of those strategies are employed. It’s the combination that’s powerful. Of course, even beyond 2035 or so, we should be moving from the paradigm of doing less evil, which is where we are right now—let’s make our buildings pollute less, let’s make them less stupid—to make them smart. Move from the turd-polishing to make them jewels. That is a hard job, and people are just dabbling in the research community, but it’s probably not something where anyone needs to go out and build a whole bunch of buildings. We have to figure this out. We’ve got a lot of normal buildings that we can do a lot easily on.So, producing energy, cleaning air and water—that’s one of the things green roofs are supposed to do, right? You can actually clean some of the air and water around the building, enhance the local ecology—you know, let raccoons live on your roof. Reuse materials, use materials that are low-impact recycled, that don’t use as much energy. But that’s really far down the road. We’ve got a lot of problems to solve in the next three months, let alone the next three years, that are much more fundamental. Clearly, cheap oil is running out. There could be some pretty profound changes, and maybe right now we’re in the midst of that. Energy security is a real challenge, particularly when you think about climate change limitations. By definition, green buildings use fewer resources over their life—over the expected design life. One of the ways to know that is to count. How much energy, how many yards of concrete—that’s one of the ways to assess this. So, just for someone to say they’re green is about as useless as just saying they’re green. It doesn’t mean anything. Everyone’s green. And then, efficiency and renewables, which are going to be the path forward—at some point, that’s where we’re going to put all of our efforts—will require lots of retrofit and will require a lot higher efficiency than we already have in our buildings. We need to take our buildings to a much different level: Somewhere between reducing energy consumption by one-half to two-thirds is where we probably should go before we start putting a lot of effort into renewables. But when you do that you can get some pretty nice combinations.last_img read more

Rolling Shutter vs Global Shutter: What’s the difference?

first_imgFilmmakers and video pros need to know the difference between rolling shutter and global shutter. Here are the basics.An important part of the production process is understanding the difference between rolling shutter and global shutter. Both are distinct in terms of the final image result, especially when the camera is in motion. Let’s take a close look at the ins and outs of each and how they affect our final production.What Is Global Shutter?We’ll start with the cinematic standard of global shutter, which has more to do with a camera’s sensor than being a process or effect. A global shutter sensor would be a CCD sensor, however most of the digital cameras being used today —  like the ARRI ALEXA — employ a CMOS sensor that utilizes global shutter to capture an entire frame all at once.Image via REDAs you see in the image above, the sensor is either on or it’s off. Digital cameras like the ARRI ALEXA utilize this feature when capturing imagery, which in turn allows the camera to capture all of the motion at once instead of progressively capturing motion like a rolling shutter. More on that shortly.Let’s take a quick look at the difference between a global shutter and a rolling shutter and the results yielded by having a global shutter capture all of the visual information at once.Video via SonyWhat Is Rolling Shutter?Image via WikipediaSo what is about rolling shutter that makes the blades of the helicopter in the video above bend and warp? Well, unlike global shutter where the sensor is exposed all at once, a rolling shutter is exposed in a progressive motion. You can see an example of this exposure in the image below and see how a rolling shutter is “always active and ‘rolling’ through pixels from top to bottom.” It is this progressive exposure that causes the warping. But as we’ve touched on before, there are ways to deal with rolling shutter in your footage.Image via SLRLoungeIt’s important to note that the rolling shutter effect often goes unnoticed, as long as the camera movement isn’t too chaotic. In fact, Blackmagic Design recently dropped global shutter in the URSA Mini 4.6K and decided to keep the rolling shutter instead. While this isn’t what Blackmagic ultimately wanted to do, it was an acceptable trade-off to ensure the 4.6K was able to reach up to fifteen stops of dynamic range. Also, keep in mind that you can utilize rolling shutter to your advantage in certain situations. For one such situation, check out the video (via Kyle Jones) below.A Quick OverviewAs you can see from the breakdowns above, there are stark differences between global and rolling shutter. However, if the information above isn’t enough (or a little difficult to fully grasp), then check out this clip from Videomaker. It offers simple examples of the differences between global shutter and rolling shutter.Was this breakdown helpful?
