Googles new Nest Hub Max smart display has a camera Can you

Can you trust it? • See All Now playing: Watch this: The Google Nest Hub Max soups up the smart display A new frontier for privacy”We have to be better about our transparency, about how we actually deal with your data and your devices inside your home.” Rishi Chandra, the Google VP in charge of the new Google Nest brand, talked with me last week at Google headquarters in Mountain View, CA about the Hub Max and the challenges of privacy in a home with a variety of cameras and sensors. “As we are defining our privacy principles, one thing we wanted to commit to was any time a camera is streaming information to Google, whether it’s through a Google Duo call or a Nest Cam feature, we want to be very transparent to the user that it’s happening.”The Hub Max indicates that the camera is recording with a green light and a message on the screen. The green light will always be on when it’s recording, even if you’re not home and checking on the stream from your phone. You won’t be able to use the Hub Max to secretly spy on anyone.

Angela Lang/CNET Google debuted a device called the Nest Hub Max at its Google I/O developer conference on Tuesday. It’s the first product under the new Google Nest brand, which combines the formerly distinct Google smart home and Nest teams. The Hub Max features a 10-inch high-definition touchscreen, powerful speakers, always-listening microphones and an embedded camera that can recognize your face.Just a few months ago, Google launched a similar but smaller product called the Google Home Hub, which will be renamed the Google Nest Hub to showcase the new brand. The Nest Hub doesn’t have a camera, and Google touted the omission as a way to give privacy-focused customers peace of mind. The camera on the Hub Max is the smartest cam on any smart display. In addition to recognizing your face, you can use it as a security monitor and get alerts if it detects motion. It’s also smart enough to recognize gestures and track your motion if you’re moving around while on a video call. The Hub Max is impressive, but it’s also potentially worrisome to have a camera like that watching you in your home. Google undoubtedly understood the concerns people would have with the Hub Max. Here’s how the search giant intends to keep your privacy intact with the Hub Max.Also read: Tell Google Home ‘stop’ and you can go right back to sleepGoogle slashes prices on its Home Max, Nest Hub and Google Home Share your voice 7 Aug 12 • Google will ask you to migrate your Nest account soon: Here’s what you need to know See it Mentioned Above Nest Cam Chandra noted that the mandatory green light is actually a shift for Nest Cams. Their default setting is to show a green light when they’re recording, but previously you could turn that off in the settings. Google is removing that option. While this move removes a customization option from the cam, it’s part of what Chandra called a new set of privacy principles from Nest.”We want to make sure that we as Google are transparent to everyone,” Chandra said. “When it’s going to Google, when it’s being recorded, that we are transparent to any user that comes into your house, whether it be the babysitter, the nanny, your guests, your family members, what have you.”Chandra noted that these steps are necessary as we move away from tech that’s strictly personal, such as a smartphone, toward tech that needs to be both communal and personal. He called the Google Nest Hub Max a representation of how the company wants to approach this dichotomy while keeping privacy intact. Anyone can interact with the Hub Max, but the Face Match feature allows it to also offer personalized notifications and information. Chandra called Face Match an example of how Google can “rethink the computing model to do really helpful things, but in a privacy sensitive way.” google-nest-hub-max-18The Hub Max can show personalized notifications after it recognizes you. Angela Lang/CNET The Face Match feature is optional. Chandra said the Hub Max will store all face models on the device itself and it will perform the processing locally as well so that the information never leaves the Hub Max. Blake Kozak, a senior analyst at smart home and security analysis firm IHS noted that as far as security cams in general, on-device storage provides “an enhanced-level of security compared with cloud-storage. By storing footage locally, consumers can rest assured that the risk of hackers gaining access to the footage is far less than if the footage is stored in the cloud.” Several Google representatives also noted that Face Match is meant solely as a personalization feature and it’s not meant for security. You won’t be able to make purchases on the Hub Max verified only by your face.Cameras and dataThe mute switch on the back of the Nest Hub Max will also function as a hard switch for the camera. It will essentially cut power to the cam so it can’t be used. Even though the switch is functionally the same as a physical shutter, I’m sure an actual physical shutter would give added peace of mind to some shoppers.google-nest-hub-max-6The mute switch cuts the power to the camera. Angela Lang/CNET “Overall, many manufacturers, especially in Europe, are making security cameras with shutters,” said Kozak. “So when the camera is off or not recording, it is clear for the consumer that their privacy is intact.”In addition to disabling Face Match, you can use the settings in the Google Home app to disable any drop-in viewing of the camera — so you won’t be able to check on the live feed of the cam when you’re out and about.You’ll also find a tab in the Google Assistant app settings called “You.” While the tab can help you see more personalized search results and organize your contacts, it will also house your activity history and privacy settings in one place so you can easily make changes.Competing for privacyGoogle isn’t the only company with a renewed emphasis on privacy. Last week, Facebook touted a new focus on privacy at the company’s F8 developer conference. CEO Mark Zuckerberg said “The future is private” and announced scholarships to help students create secure and private artificial intelligence. Facebook has been mired in privacy scandals recently, including the Cambridge Analytica scandal and mishandling customer data.Amazon, Google’s main competitor in the smart home space, came under fire recently when it was revealed that Amazon workers listened to your conversations with the company’s digital assistant and had access to private data. Google faced backlash recently as well after it was revealed that the hub of the Nest Secure system — the Nest Guard — had a built-in hidden microphone.With the Hub Max’s new facial recognition abilities, Google is stepping into an area of tech with lots of privacy implications. Storing all Face Match data locally is a nice touch, but you can still use the cam as a security device and with Nest’s premium Nest Aware subscription, it can use facial recognition to customize alerts based on who it sees.If having an extra camera in your home will make you worried, Google will continue to offer the cameraless Google Nest Hub. As far as the Hub Max, Google is saying the right things at the very least. I also appreciate the new “You” tab and hope it legitimately makes it easier to manage your privacy and usage settings. That said, only time will tell if the company’s promises of privacy will hold up to its growing roster of increasingly personalized smart home gadgets.

Nation observes National Mourning Day today

first_imgBangabandhu Sheikh Mujibur RahmanThe nation observes the National Mourning Day today, Wednesday, with due reverence and solemnity, marking the 43rd anniversary of assassination of father of the nation Bangabandhu Sheikh Mujibur Rahman, reports UNB.Sheikh Mujibur Rahman – the architect of the country’s independence — was assassinated along with most of his family members at the crack of dawn on 15 August 1975 by a cabal of army personnel.The killing of Bangabandhu, the greatest son of the soil in thousand years, descended a pall of gloom and spread a sense of deep sadness among the people in the country and across the globe.The world protested and condemned the killing saying it is an irreparable loss to millions of people of Bangladesh.His two daughters — Sheikh Hasina, now the prime minister, and Sheikh Rehana – luckily survived the massacre as they were abroad at that time.Eighteen members of the family along with Bangabandhu’s wife Sheikh Fazilatunnesa Mujib, three sons — captain Sheikh Kamal, lieutenant Sheikh Jamal and Sheikh Russel –, two daughters-in-law — Sultana Kamal and Rosy Jamal –, brother Sheikh Naser, peasant leader Abdur Rob Serniabat, youth leader Sheikh Fazlul Haq Moni and his wife Arzu Moni, Baby Serniabat, Sukanta Babu, Arif and Abdul Nayeem Khan Rintu were killed on the fateful night.Bangabandhu’s military secretary colonel Jamil Uddin Ahmad (Bir Uttam), who was later promoted posthumously to the rank of brigadier general, was also killed during the massacre. Some members of a family at Mohammadpur in the capital were killed by artillery shells fired by the killers on the same day.The day is a public holiday.The government, different socio-cultural, political and professional organisations including ruling Awami League and its associate bodies have taken various programmes to mark the day.The nation, however, started observing the month of mourning from 1 August, recalling the most brutal killing in its history and renewing the pledge to safeguard perpetually the country’s independence and sovereignty.President Abdul Hamid and prime minister Sheikh Hasina pay tributes to Bangbandhu at the Bangabandhu Memorial Museum at Dhanmondi Road No. 32 at 6:30am.Programmes there include a guard of honour by a smartly turned out contingent of the Armed Forces, to the portrait of the Bangabandhu. A special munajat and fateha is scheduled to be offered there.Premier Sheikh Hasina is expected to place wreaths at the graves of the members of Bangabandhu’s family and other martyrs at Banani graveyard.She is also scheduled to place wreaths at the Bangabandhu Mausoleum in Tungipara of Gopalganj at 10:00am and take part in a milad and doa mahfil there.Meanwhile, president Abdul Hamid and prime minister Sheikh Hasina issued separate messages commemorating the National Mourning Day.In his message, the president said this barbarous occurrence was rare not only in the history of Bangladesh but also in the history of the world.”The country is now free of disgrace through the trial of the tragic killing of 15 August. The verdict of fugitive killers will soon come into force – this is the expectation of the countrymen on the National Mourning Day,” he said urging all to follow the path shown by the Father of the Nation and devote themselves to turn the country into a ‘Golden Bangla’.In her message, the prime minister said, “Under the dynamic, courageous and charismatic leadership of the father of the nation, the people of this territory brought the reddish sun of the independence breaking the shackles of subjugation of thousands of years. The Bangalees got their own nation-state, flag and national anthem.”But Bangabandhu Sheikh Mujibur Rahman was killed at a time when he had undertaken an arduous task of building a ‘Golden Bangladesh’ reconstructing the war-ravaged country and unifying the whole nation, she said.The killers were able to assassinate Bangabandhu Sheikh Mujibur Rahman but they could not erase his dreams and ideals, the prime minister said urging all to turn the grief of the loss of Bangabandhu into strength, build a non-communal, hunger-illiteracy-free, and happy, prosperous Bangladesh and establish ‘Golden Bangladesh’ as dreamt by the father of the nation.On the day, the national flag will be kept half-mast at government, autonomous, semi-autonomous, educational institutions, private buildings and Bangladesh missions in abroad.A doa will be offered after Zohr prayers in all mosques across the country while special prayers will be arranged in temples, pagodas, churches and other worship places at convenient time across the country.Bangladesh Betar, Bangladesh Television and private TV channels and radio stations will air special programmes highlighting the life, struggle and achievements of the great leader while newspapers will bring out supplements on the occasion.Islamic Foundation of Bangladesh and Bangabandhu Gabeshana Parishad will also arrange programmes on the occasion.Besides, specially designed posters will be displayed at educational institutions and other public places, reminding the black chapter of the country’s history.Shishu Academy, Bangabandhu Memorial Museum and many other educational institutions will organise discussions on Bangabandhu’s life and works.The district and upazila administrations will observe the day through doa mahfil and discussions in line with the national programmes.Different institutions, socio-cultural organisations and people from all walks of life will place wreaths at Tungipara and at the portrait of Bangabandhu at Dhanmondi, Road No. 32, and will hold doa mahfils and discussions there.The different organisations and directorates under the information ministry will also hold different programmes, including exhibition, publish special supplements of Nirikkha, Sachithra Bangladesh and Bangladesh Quarterly.Bangladesh Television has taken initiatives to read out the Bangabandhu’s books – “Osomapto Atmajibani” and “Karagarer Rojnamcha”.Awami League (AL) will keep the national flag and the party flag at half-mast while black flag will be hoisted at the Bangabandhu Bhaban and all other offices of the party across the country.AL and it associate bodies will place wreaths at the portrait of Bangabandhu at Dhanmondi Road No. 32 in the morning. Leaders, workers and supporters of AL and other organisations will also pay homage to the martyrs of 1975 at the Banani graveyard, offer Fateha and munajat there on 15 August.AL will distribute special foods among the poor, destitute and orphans. The party will hold milad mahfil and offer doa at Bangabandhu Bhaban after Asr prayers on 15 August, reports BSS.It will organise a discussion meeting at Bangabandhu International Conference Centre (BICC) at 4:00pm on 16 August.A delegation of the Awami League central executive committee will visit the shrine of Bangabandhu in Tungipara on 15 August.Shishu Academy, Bangabandhu Memorial Museum and many other educational institutions and organisations will organise discussions on Bangabandhu’s life and works.Bangladesh missions abroad will arrange discussions with hoisting the national flag half-mast atop their respective offices.last_img read more

Britains US ambassador resigns after Trump spat

first_imgIn this file photo taken on October 20, 2017 British Ambassador to the US Kim Darroch speaks during an annual dinner of the National Economists Club at the British Embassy in Washington, DC. Britain`s ambassador to Washington Kim Darroch said on July 10, 2019, he was resigning after drawing US President Donald Trump`s ire for criticising his administration in leaked confidential cables to London. `The current situation is making it impossible for me to carry out my role as I would like,` Darroch wrote in his resignation letter. `I believe in the current circumstances the responsible course is to allow the appointment of a new ambassador.` AFPBritain’s ambassador to Washington Kim Darroch said Wednesday he was resigning after drawing Donald Trump’s ire for calling the US president “inept” in leaked confidential cables to London.Darroch said in a resignation letter to the Foreign Office that the scandal made it “impossible” for him to continue representing British interests in the United States.Trump has said his administration would no longer “deal” with Darroch.”Since the leak of official documents from this Embassy there has been a great deal of speculation surrounding my position and the duration of my remaining term as ambassador,” Darroch wrote.”I want to put an end to that speculation. The current situation is making it impossible for me to carry out my role as I would like,” he said.”I believe in the current circumstances the responsible course is to allow the appointment of a new ambassador.”Prime Minister Theresa May told parliament moments after Darroch’s resignation that the criticism he faced was “beyond unfair and wrong”.”I think he’s given honourable and good service and he should be thanked for it,” she said.The Mail on Sunday’s publication of Darroch’s cables set off a political firestorm in London and saw Trump launch two successive days of Twitter attacks against the envoy and May.One of the cables called the Trump administration “uniquely disfunctional” and another characterised the US leader as “inept” and “insecure”.Trump tweeted Monday that Darroch “is not liked or well thought of within the U.S. We will no longer deal with him.” He also welcomed the “good news” that Prime Minister Theresa May was stepping down in two weeks.The US leader followed that up on Tuesday by calling “wacky Ambassador” Darroch “a very stupid guy”.The scandal saw Darroch taken off the guest list of a dinner attended by Trump on Monday.He also missed visiting UK Trade Minister Liam Fox’s talks in Washington on Tuesday with the president’s adviser and daughter Ivanka Trump.last_img

Migrant Caravan Prompts Trump Administration To Send More Attorneys Judges To Border

first_img Share Robin Jerstad for The Texas TribuneA Border Patrol agent closes a gate at the Eagle Point development in Eagle Pass.The Trump administration on Monday announced it was sending more federal immigration attorneys, judges, prosecutors and asylum officers to the border to prepare for a possible influx of Central Americans arriving as part of an annual caravan – with the aim of swiftly prosecuting the migrants and, in many cases, returning them to their home countries.Department of Homeland Security Secretary Kirstjen Nielsen said in a statement that members of the caravan who enter the country illegally will be referred for prosecution and others seeking asylum will be adjudicated quickly and deported if their claims are without merit.“If you enter the United States illegally, let me be clear: you have broken the law. And we will enforce the law through prosecution of illegal border crossers,” Nielsen said in a statement. “DHS encourages persons with asylum or other similar claims to seek protections in the first safe country they enter, including Mexico.”The caravan of Central Americans is an annual event but this year’s, which began late last month, drew the attention of President Donald Trump and resulted in his call to send the National Guard to the border. He later said the decision was also spurred by last month’s spike in apprehensions on the southern border.The caravan grew at times to more than 1,500 people but largely disbanded in Mexico. A few dozen, however, carried on until they reached the United States, including about 50 who crossed into the country from Tijuana late last week, Reuters reported.It’s unclear how many migrants from the caravan remain and whether they are still on their way to the U.S., but Nielsen said the government was deploying more resources to deal with a possible influx.“DHS, in partnership with [the Department of Justice], is taking a number of steps to ensure that all cases and claims are adjudicated promptly,” she said. Those steps, she said, include sending additional attorneys from U.S. Immigration and Customs Enforcement, additional asylum officers from U.S. Citizenship and Immigration Services and additional immigration judges and prosecutors from the Department of Justice to the border.Benjamin Johnson, the executive director of the American Immigration Lawyers Association, said that the extra resources “might be good optics” but that whether good policy would result from it would be determined by what the extra staff is expected to do.“If their mandate is to move quickly, then you have undermined the commitment to ensuring somebody is looking at the facts of the case and deciding whether in fact those people are entitled to protections under our law,” he said, referring to Central Americans who are seeking asylum due to violence in their home countries.On Monday morning, the president reiterated his call for his promised border wall and said ongoing negotiations over the future of the North American Free Trade Agreement could be affected by how Mexico enforces its own immigration laws.“Mexico, whose laws on immigration are very tough, must stop people from going through Mexico and into the U.S.,” he tweeted. “We may make this a condition of the new NAFTA Agreement. Our Country cannot accept what is happening! Also, we must get Wall funding fast.”last_img read more

Connecticut WWIIEra Newspapers Offer View of Black Life

first_imgBy Susan Haigh, The Associated PressA detailed account of African-American life in the Northeast during World War II, carefully preserved in the basement of the Connecticut State Library, has been uploaded for a new, modern readership.Hunched over a lighted magnifying machine, Christine Gauvreau spent months scrolling through reels of microfilm of Black-owned and operated Connecticut newspapers, preparing them to be digitized. They’re some of the latest entrants in the Chronicling America project, a partnership between the National Endowment for the Humanities and the Library of Congress to create a national digital database of historically significant U.S. newspapers published between 1690 and 1963.This Nov. 29, 2018 photo shows an original April 23, 1949 copy of the New England Bulletin, Black-owned and operated weekly newspaper in Hartford, Conn. Old microfilm of this and other incarnations of the newspaper are being digitized so they can be available online as part of the United States Newspaper Program. (AP Photo/Susan Haigh)“It’s really a document from the very early civil rights movement in Hartford,” said Gauvreau, who recently finished archiving old issues of the now-defunct Connecticut Chronicle, Hartford Chronicle, Hartford-Springfield Chronicle and New England Bulletin, a family of Black-owned and operated newspapers that began in 1940 and operated consecutively for about a decade.Connecticut’s latest additions to Chronicling America mark the first African-American newspapers added to the project from a Northeast state.The four Connecticut-based weekly newspapers upheld a “crusade tradition” of journalism, Gauvreau said. They pushed for the hiring of Hartford’s first Black firefighters and Black bus drivers; advocated for a law barring racial bias in the National Guard; and exposed substandard housing, inferior quality goods and high prices in Harford’s North End neighborhood. In an April 23, 1949 article, the New England Bulletin criticized the “vacillating stand” taken by Connecticut’s State Board of Education, which agreed to allow public high school field trips to “jimcro” Washington D.C. “even though Negro students are segregated” at certain hotels.In a front page editorial published in May 14, 1949, readers were urged to write to the State Board of Education ask members to “STOP PASSING THE BUCK” and prove “beyond a shadow of a doubt that the board is very much against segregation.” The editorial said the New England Bulletin was taking a stand and criticizing the board for allowing the trips because the decision was “contradictory to the forward-looking policies of the state with regard to any kind of racial injustice.”An Oct. 5, 1946 column by James E. Shankel, editor of the Hartford Chronicle at the time, wrote about “bare-faced racial discrimination” in Connecticut. He noted a member of a New Haven church had come across a letter from an East Haddam developer advertising lakefront lots for sale and how “this summer colony is restricted to the Caucasian race.”“Obviously, this advertising letter form was never intended to fall into the hands of prospective Negro buyers,” Shankel wrote.Other pages of the newspapers provide a window into the culture of the time. Articles cover everything from an Easter sermon at Mount Calvary Baptist Church to performances by musical greats. One advertisement announces a scheduled performance by iconic jazz singer Ella Fitzgerald at the State Theater in Hartford. Written by correspondents stationed throughout the state and region, many articles chronicle the accomplishments of Black residents. One headline announces “City’s Only Army Nurse Returns,” a reference to a Black nurse from Hartford who was honorably discharged from the Army Nursing Corps.“They wanted to tell the story about what was happening in Black Hartford. They also wanted to highlight issues of discrimination. They wanted to celebrate Black achievement at the same time,” said historian and Professor Stacey K. Close, the associate provost and vice president of equity and diversity at Eastern Connecticut State University. “During World War II, there was a push to improve the employment of African-Americans in terms of the city and the state. And this newspaper took up the challenge.”There was also an effort by the newspapers to make the readers aware of what was happening elsewhere, especially in the southern states where many still had family members.“They also made sure that young people knew what was going on in the rest of the country,” Close said.He added “there was an urgency” to what the newspapers were doing.“They were trying to push the city to do better than they had done in the past,” he said. “They were an organization and a paper pushing for social, economic and political change.”last_img read more

How Much Energy Goes Into Making a Bottle of Water

first_img Perception, Status and Bottled Water Explore further Citation: How Much Energy Goes Into Making a Bottle of Water? (2009, March 17) retrieved 18 August 2019 from https://phys.org/news/2009-03-energy-bottle.html Researchers have calculated that the energy required to produce bottled water is up to 2,000 times more than the energy required to produce tap water. Image credit: Wikimedia Commons. (PhysOrg.com) — Most people who buy bottled water have access to clean drinking water virtually for free (in the US, tap water costs less than a penny per gallon, on average). Nevertheless, the consumption of bottled water continues to grow, far surpassing the US sales of milk and beer, and second only to soft drinks.center_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Since world consumption of bottled water has increased by 70% since 2001 to 200 billion liters in 2007, some people have become concerned about the environmental, economical, and social impacts of bottled water. In a recent study, researchers Peter Gleick and Heather Cooley from the Pacific Institute in Oakland, California, have estimated the energy required to produce bottled water, including the energy required to manufacture plastic, fabricate the plastic into bottles, process the water, fill and seal the bottles, transport the bottles, and chill the bottles for use.Combining all the energy input totals, Gleick and Cooley found that producing bottled water requires between 5.6 and 10.2 million joules of energy per liter, depending on transportation factors (a typical personal-sized water bottle is about 0.5 liters). That’s up to 2,000 times the energy required to produce tap water, which costs about 0.005 million joules per liter for treatment and distribution. In 2007, US consumers purchased more than 33 billion liters of bottled water, or 110 liters (30 gallons) per person. The total energy required to produce 33 billion liters is equivalent to 32-54 million barrels of oil (although not all the energy used comes from oil). Energy to produce bottled water accounts for about one-third of one percent of total US energy consumption.To break down the energy requirements, Gleick and Cooley found that producing the plastic bottles and transporting the bottles greatly dominated the energy input. Most single-use plastic water bottles are made out of polyethylene terephthalate (PET), recognized in the US by the recycling code “1” imprinted on the bottle. Large containers are more likely made of polycarbonate, which requires about 40% more energy to produce than bottle-grade PET. Although some companies are experimenting with producing lightweight bottles, the researchers calculated that the manufacturing cost of PET is about 4 million joules of energy per typical 1-liter PET bottle weighing 38 grams, and the cap weighing 2 grams. Even though using recycled materials could lead to some energy savings, almost all plastic bottles for water are currently made from virgin PET. “Our previous work had suggested that bottled water production was an energy-intensive process, but we were surprised to see that the energy equivalent of nearly 17 million barrels of oil are required to produce the PET bottles alone,” Cooley told PhysOrg.com.Transportation costs vary depending on the distance and mode of transport, and both factors depend on the type of bottled water. There are two main kinds of bottled water in the US: “spring water,” which comes from an underground spring, and accounts for 56% of US sales; and “purified water,” which is municipal tap water that has received further treatment, and accounts for 44% of US sales. Spring water can only be derived from certain locations, while purified water can be produced locally. (In the US, Nestlé is the largest producer of spring water, while Coca-Cola (Dasani), Pepsi (Aquafina) and Nestlé (Pure Life) account for most of the country’s purified water sales.)In their analysis, Gleick and Cooley evaluated three different transportation scenarios, and calculated the energy requirements per liter of bottled water. For purified water distributed locally by truck within Los Angeles, the total transportation energy is about 1.4 million joules per liter. In the second situation, spring water shipped from Fiji (such as Fiji Spring Water) across the Pacific to Los Angeles, and then delivered locally by truck, requires about 4 million joules per liter for transportation. Third, spring water transported by truck from French springs (such as Evian) to French sea ports, then shipped across the Atlantic, transported by train from the east coast to Los Angeles, and then delivered locally by truck has a transportation energy cost of about 5.8 million joules per liter. For the two spring water scenarios, the transportation energy equaled (in the case of Fiji) or exceeded (in the case of France) the energy required to produce the bottle.The energy required for processing, bottling, sealing, labeling, and refrigeration were much smaller than the energy for making the bottles and transporting them. With this data, the researchers hope that future studies will have the ability to make specific estimates for different scenarios, and possibly find ways to cut energy costs.“With the US consumption of bottled water exceeding 33 billion liters a year, and with intensifying efforts to reduce energy use and greenhouse gas emissions, these data should help identify ways to reduce the energy costs of bottled water and may help consumers themselves make more environmentally sustainable choices,” Cooley said.More information: Gleick, P.H. and Cooley, H.S. “Energy implications of bottled water.” Environmental Research Letters 4 (2009) 014009 (6pp).Copyright 2009 PhysOrg.com.

NextGen WiFi Is Here

first_imgMarch 16, 2009 As if it isn’t hard enough keeping track of all the next-gen Wi-Fi terms (802.11n, draft-n, and so on), you then have to figure out what the heck they mean. In the Wi-Fi space, draft-n is the new, faster, stronger, more reliable form of Wi-Fi. More than 25 percent of the Wi-Fi devices shipped in 2008 supported draft-n, says Edgar Figueroa, executive director of the Wi-Fi Alliance. He points to ABI research that estimates by 2012, 90 percent of all devices will support it.Fortunately, old and new versions can work and play in harmony. So while “there probably won’t be a time when it’ll be absolutely necessary to upgrade,” says Figueroa, “the market is naturally moving toward the best technology.” And next-gen is where it’s at.Draft-n gear can provide significant improvements to your network, including five times the throughput (up to 250 Mbps) and twice the range (up to 200 meters). So if you’re trying to decide if it’s time to upgrade your office to draft-n Wi-Fi, consider these questions:Do you have 15 or more employees using entry-level gear or 40 or more employees using enterprise-level gear?Are you expanding your office size?Does your office setup have hard-to-reach coverage areas–for example, numerous floors or rooms within a building?Do you frequently use real-time or high-bandwidth applications, such as web conferencing, VoIP or streaming HD video?If you answered yes to any of these questions, then it might be time to upgrade. The good thing about draft-n is that it’s backward compatible, meaning it works with previous versions (and vice versa). This allows for an easier, gradual transition. So if you’re not in the financial position to upgrade all your Wi-Fi devices at once–who is really?–you can switch out a few, or even just one, at a time, Figueroa explains. “Yet that device offers benefits to all the old devices already using the network.” Hear from Polar Explorers, ultra marathoners, authors, artists and a range of other unique personalities to better understand the traits that make excellence possible. 2 min read How Success Happens This story appears in the April 2009 issue of Entrepreneur.
