Explore further In their study, Hisashi Ohtsuki of the Japan Science and Technology Agency and the Tokyo Institute of Technology, along with Martin Nowak of Harvard University, have investigated how evolution might have first begun. As the researchers explain, the origin of life is a transition from chemistry to biology, and has been widely studied. Here, Ohtsuki and Nowak have presented a model where a purely chemical system (prelife) becomes more efficient (catalytic prelife) and then builds the sequences needed for replication, finally resulting in life. Their work is published in a recent issue of Proceedings of the Royal Society B.“As you know, the ability of replication is critical for life,” Ohtsuki told PhysOrg.com. “We can conceive several forms of life, such as prelife catalysts and replicators, as in our paper. We are interested in which form of life is most efficient and thus is selected in prelife (a soup of chemicals). The significance of our study is that we have mathematically shown for the first time that replicators, which have the ability to remain attached with a growing sequence, have a great advantage over the other forms of life. Replication is usually taken for granted in the study of evolution. We think that our result gives a justification of why replicators are so dominant.”In the scientists’ model, prelife is made of two types of monomers (0 and 1) that randomly link together to form a polymer chain. By adding a 0 or a 1, longer chains are produced from shorter ones. The researchers created a simple tree of life based on this growth process, where either a 0 or a 1 is added to the end of the preceding chain to make a longer one. Though starting with just a single monomer, this tree of prelife has infinitely many lineages. As the researchers explain, some of these prelife sequences are catalysts, and can enhance certain reactions in prelife. Specifically, they increase the rate at which monomers are added to sequences in the specific prelife reactions that created them. The faster the rate of reactions to create a certain prelife catalyst, the more of them there will be. As the researchers found, the sequences that are most highly selected among prelife catalysts are perfectly catalyzed prelife sequences (those that enhance the rates of all their upstream reactions). (PhysOrg.com) — Life’s ability to replicate itself is essential for evolution, yet even the simplest kind of replication requires a relatively complex system. So what kind of non-replicating system might have served as the predecessor of evolution, paving the way for life as we know it? The answer, according to a recent study, is a kind of “prelife” — a chemical system that can lead to information and diversity, and that is capable of selection and mutation, but does not yet have the ability to self-replicate.center_img “Prelife refers to chemical reactions in a soup of chemicals that consists of amino acids, phosphoric acids, nucleobases, and so on,” Ohtsuki explained. “Simply speaking, prelife supplies ‘materials’ for life. But prelife does not have an ability of replication, because it cannot catalyze any reactions. Catalytic prelife is a big step forward for life, because it can enhance certain reactions. A most promising candidate for life among prelife catalysts are those which can catalyze their own upstream reactions. We believe that catalytic ability is a big step, yet not enough for the emergence of life, as we have shown in our paper: we need another step, that is, replicators.”Replicators – for example, a simple sequence of all 0 monomers – are among the sequences that prelife dynamics can create. The difference between a replicator and a perfect prelife catalyst, as the researchers explain, is that a prelife catalyst attaches to a sequence to increase the rate at which an activated monomer is added, and then detaches itself. In contrast, a replicator remains attached to the growing sequence. “The fundamental difference lies in that replicators can remain attached to a growing sequence so that it can ‘go along’ with it,” Ohtsuki explained. “By doing so, replicators need to attach to a template only once to complete the replication. On the other hand, prelife catalysts have to attach to and detach from the target sequence many times, because in each reaction the target extends in length by one. Therefore, a longer prelife catalyst must catalyze its upstream reactions a number of times, resulting in an inefficient replication.”Overall, replicators have certain advantages over catalytic prelife that cause the replicators to be selected over prelife. As the researchers explain, ongoing competition between prelife and catalytic prelife creates certain selection thresholds that limit the lengths of the sequences. Most importantly, the researchers found that catalytic activity must increase exponentially with sequence length to keep its abundance high; otherwise a longer sequence becomes less abundant. In contrast, the threshold of replicator activity converges to a fixed value, suggesting that even long replicators can sustain its high abundance. For replicators, the critical replication rate is almost independent of the rate of the replicator. As prelife catalysts and replicators compete for the same resources (monomers), this ability to grow longer is what gives replicators their edge, ultimately leading to the origin of evolution.More information: Hisashi Ohtsuki and Martin A.

Microsoft to patch 17yearold bug

0 Comments

first_img A security researcher for Google, Tavis Ormandy, found several flaws in the Virtual DOS Machine (VDM) utility that enables more recent releases of Windows to run old DOS and 16-bit software. The bug has the potential to enable an unprivileged 16-bit program to gain system privileged access level to the PC, which would allow attackers to get their own code to run. Ormandy found the bug and reported it to Microsoft over seven months ago and published a workaround, but a patch has not been ready until now. The 17-year-old bug affects only Windows 32-bit versions and does not affect 64-bit machines, which does not have support for 16-bit applications. Microsoft has released a security advisory, which says the company is not aware of any attacks involving the vulnerability, and most users are at low risk, apparently because local access to the computer is required.Among the 25 other patches included in this month’s security update are five “critical” vulnerabilities that could allow an attacker to hijack a PC running Windows and force it to run their own programs. The update also fixes bugs in Microsoft Office 2003 and XP, and Office 2004 for Apple Macintosh. © 2010 PhysOrg.com Microsoft’s monthly security fixes spare Windows 7 This document is subject to copyright.

Japanese scientists explore electric roads for EVs

first_imgA schematic of the proposed power transfer system. This system transmits electric power thorough a capacitor composed of a steel belt and a metal plate attached to the road, and the power feed in differential mode. More information: www.tut.ac.jp/english/newslett … overtures/index.html (PhysOrg.com) — Masahiro Hanazawa of Toyota Central R&D Labs and Takashi Ohira from Toyohashi University are working on a solution for avoiding battery recharge headaches in powering electric cars. They are working on a prototype of electric cars that are powered by the road itself–electric roads for electric cars. While the idea of cars powered from the ground is not new, the system that they propose is an interesting way to power electric cars as the cars travel along the road through steel belts placed inside tires and a metal plate in the road. Improving Plug-In Electric Cars © 2011 PhysOrg.com This is how the Toyohashi University newsletter report describes their system: “The source of energy from power lines is up-converted into radio frequency (RF) by high-speed inverters implanted along tracks in the road. The RF voltage is applied to a balanced metal track embedded under the surface of the road. The EV picks up the RF voltage via electrical capacitance between the metal and a steel belt installed inside of the tires of the EV.”In their experiments, the researchers put small metal plates on the floor and inside a tire, and positioned another metal plate above the tire. They measured the electrical impedance between the two plates. The team presented their work in May at the International Microwave Workshop Series on Innovative Wireless Power Transmission in Kyoto, Japan. While their tests involved low voltages, the researchers believe energy transfer from the road to a running automobile is feasible. With enough power the system could run typical passenger cars, says Ohira.Their system would require smaller battery packs, rather than heavier packs, to get back and forth from electrified highways, which is viewed as a benefit as well.

Microsoft creates mood sensing software for smartphones

first_img Most people realize that their smartphone has a lot of embedded technology in it that interacts with the world at large—GPS hardware, accelerometers, etc. all monitor activity and use that data to provide useful functions, such as automatically switching from landscape to portrait mode when a phone is rotated. In this new effort, the researchers sought to discover whether software that monitors phone activities could reveal the users’ moods.To find out, the team wrote code that monitored email, texting, app usage, phone calls, location information, and browsing history, then added algorithms to guess mood based on that data. Next, they enlisted the assistance of 32 volunteers to help them test the accuracy of their code. The volunteers were asked to use the system for two months while also completing mood assessments to provide data for comparison. With no training or tweaking, the software was found to provide answers of happy, tense, calm, upset, excited, stressed, or bored that matched the actual mood reported by the volunteers, on average 66 percent of the time. After optimizing the system for the individual habits of each of the volunteers, the rate increased to 93 percent.The researchers suggest third party hooks could be added to the software to allow for automatically transmitting user moods to applications like Facebook. They also acknowledge that privacy concerns could arise if the software were to be delivered to the public, but suggest the benefits of such software would likely outweigh such concerns. They note that sites like Netflix or Spotify could use data from MoodScope to offer movies or other content based on specific users’ moods.

Easily synthesized compound found to be useful for removing fluoride and metal

0 Comments

first_imgCredit: ACS (Phys.org)—A pair of researchers at the Indian Institute of Science Education and Research Kolkata has found that an easily synthesized compound can be used to remove fluoride and metal ions from drinking water. In their paper published in the journal ACS Omega, Tanmay Das and Debasish Haldar describe how the compound was synthesized and how well it performed under various testing regimens. Called Zwitterionic spirocyclic Meisenheimer complex 1, the compound was synthesized from picric acid and N,N′-dicyclohexylcarbodiimide. The result, the researchers claim, is a compound that can be used to remove a host of pollutants from drinking water.As the researchers note, drinking water is a key resource as the world’s population increases. In addition to the water needed to quench the thirst of billions of people, water is used in agriculture to feed all those people and to create products for them to use. As they further note, pulling water from underground reservoirs to water crops leads to an increase in fluoride and arsenic in the water that is pulled up for drinking. In addition, a host of modern manufacturing processes release a wide variety of metals into streams and other water supplies.Dad and Haldar note that many methods have been developed to remove toxins in water, but they are single-purpose remedies. The researchers seek a universal compound that can remove most of the materials in one fell swoop—compound 1, they claim, appears to be that solution.After synthesizing the compound, which repels water, the researchers tested its ability to clean drinking water. They added a host of metal ions to a glass of water and then poured it through a gel containing their compound. They report that the absorption capacity was approximately 99 percent. Testing revealed that the compound was successful at removing large amounts of lead, mercury, copper, iron and fluoride—reducing most to levels below World Health Organization standards. Furthermore, they found a sponge containing the compound could be used to remove oils from water, suggesting it could also be used to clean oil spills.

DOI: 10.1021/acsomega.7b01379AbstractThe recycle, cleaning, and reuse of water are highly important for environmental remediation. This issue is addressed by creating a fluorescent zwitterionic spirocyclic Meisenheimer complex with high chelating propensity for toxic metals using low-cost starting materials and a one-pot synthesis technique. The resulting material is able to detect fluoride up to 12.8 ppb level and remove 82% aqueous fluoride from 1000 mL of 100 ppm fluoride solution in a single contact. The material demonstrates rapid kinetics and is capable of dropping the toxic metal ion (Pb/Hg/Cd) concentration below 0.2 ppb within 10 min. A resin-free, precipitation-free, and reusable technique has been developed for the removal of toxic metal ions and fluoride from extremely polluted water. Moreover, utilizing its extreme hydrophobicity, polystyrene sponges have been coated with the Meisenheimer complex to mop up oil spill and organic solvents from a biphasic mixture.center_img Study discounts fluoride as a danger for tea drinkers © 2017 Phys.org Citation: Easily synthesized compound found to be useful for removing fluoride and metal ions from drinking water (2017, November 28) retrieved 18 August 2019 from https://phys.org/news/2017-11-easily-compound-fluoride-metal-ions.html This document is subject to copyright.

first_imgEnforcement Directorate (ED) has issued summons for personal appearance to Pakistani singer Rahat Fateh Ali Khan in connection with an alleged forex violations case of 2011.The agency has initiated a probe under the Foreign Exchange Management Act (FEMA) sometime back against the singer and his associates, and has now issued summons against him to appear before investigators at the agency’s Delhi zonal office here. ‘The summons have been sent through the Indian Embassy in Pakistan. He has been summoned for presenting his case and answering agency’s questions under Section 37 of the FEMA in connection with a foreign exchange violation case,’ official sources said.The case dates back to 2011 when the Directorate of Revenue Intelligence (DRI) intercepted Khan and his manager, Marrouf Ali Khan, at Indira Gandhi International Airport (IGIA) here for allegedly carrying an undeclared $1.24 lakh and some other instruments in foreign currency. The ED which is the central agency to probe such forex contraventions under the FEMA took over the case after this episode.Emails and phone calls made by PTI to Khan’s associate and manager in Pakistan to elicit a response over the latest episode remained unanswered. Officials said ED had initiated the step after nearly finalising its over-an-year probe and after obtaining records of the said cash from RBI.last_img read more

first_imgScrambling for efforts to check seasonal rise in prices of fruits and vegetables during the July-November period, Food Minister Ram Vilas Paswan held day long consultations with state food and consumer affair ministers while Agriculture Minister Radha Mohan Singh sought to reassure of contingency plans being in place to tackle any situation arising out of rain deficiency.At the meeting chaired by Paswan, a six-month action plan was chalked out to maintain supplies and check prices of pulses, edible oil, rice, onion, tomato and potato. Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJIStates were asked to monitor wholesale and retail prices of essential commodities and make market interventions on a real-time basis. They were also asked to amend Agricultural Produce Marketing Committee (APMC) Act to remove inter-state trade barriers on staple fooditems like onions.“We will not allow unreasonable increase in prices. The state governments should take stringent action to prevent hoarding and black marketing,” Paswan said. Also Read – Health remains key challenge in India’s development: KovindAction against hoarding and black-marketing should be taken by states, and they have also been directed to identify vulnerable areas where supply shortages occur and ensure that ‘stock-out’ situations do no occur especially of items of common consumption, he said. The Union government on its part said it is considering import of 5,000 tons of urad dal, on top of a similar quantity of tur/arhar dal currently being imported. Paswan said export price of onions has already been hiked to ensure domestic availability and price check. “We do not want to create unnecessary panic. We do not want to impose inspector raj. We have given powers to states to act against hoarders,” he said, adding that 24 states and UTs have been asked to roll out food security law by September.Radha Mohan Singh assured of a contingency plan being in place in case of deficient rains, which irrigate 55 per cent of the crop in India. “So far, monsoon rains were better than expected although there is a forecast of deficit rains this year too. Farmers need not panic. We are ready with contingency plans to tackle any possible impact of poor rains on kharif crops,” he said. As per the action plan, Paswan said, states will mobilise Food and Civil Supplies Corporations, Cooperative Societies and Fair Price Shops for augmenting distribution avenues for essential food items.The Price Monitoring Cells in states will be strengthened to monitor wholesale as well as retail prices of specific commodities. The price information should enable states to make market interventions on a real time basis.However, Paswan assured that “there is no need to worry.There is adequate foodgrain stock to meet domestic demand”. He also said that prices have increased only in case of pulses and onion. Singling out hoarding as a major factor for the price rise, he suggested that states should be proactive in taking steps to prevent further spike, especially during the lean period – July to November.Hoarders and black marketeers normally get active in this period taking advantage of a demand-supply mismatch, he said.Paswan said state governments should come out with state-level action plans to combat the issue. Consumer Affairs Secretary C Viswanath said, “From June onwards, generally, we see rise in prices of some essential commodities. We have already seen increase in prices of pulses. To boost supply, we are considering import of 5,000 tonnes of urad.”He said good monsoon and relatively high support prices of pulses compared to other crops is encouraging farmers to sow pulses in more area in this kharif season, which could also help check prices of lentils.Bring law to check price hike: haryana tells centreHaryana government has urged the Central government to adopt a multi-pronged strategy to check price hike of essential commodities. A stringent law should also be enacted to check hoarding and formulation of a long-term scheme to increase production.  This was stated by Haryana Food and Supplies Minister Ram Bilas Sharma during a meeting with Union Minister of Consumer Affairs, Food and Public Distribution, Ram Vilas Paswan on Monday. Making an announcement, Ram Bilas Sharma who is also Haryana tourism minister, said the state government is going to implement a new scheme to provide subsidised food to the pilgrims coming to the sacred Braham Sarovera.last_img read more

Already drinking water scarcity has been reported from Maharastra, Madhya Pradesh and Tamil Nadu. He said awareness campaign to conserve drinking water will be launched. Drinking water is used to wash cars, water the roadside trees, cleaning, flushing and gardening. Moreover, in many areas filtered water is wasted through the roadside taps. Around 40 million gallons of filtered water is wasted every day. Many people said as there is no water tax in Bengal people waste drinking water. The KMC supplies 44.50 crore gallon of filtered water daily.

There was separate overhead tanks to store unfiltered water. This water was used for flushing. The system of cleaning the city roads with unfiltered water was stopped following outbreak of Cholera in the mid 1960s after some slum dwellers consumed unfiltered water. If rainwater is harvested, then this water will be used for cleaning, flushing, gardening and washing cars. It may be mentioned that Shanta Sheela Nair, Commissioner of Chennai Municipal Corporation was first to make rainwater harvesting mandatory in India. Later, it was used by the Rajasthan government. It may be mentioned that in New Town, a pilot project on rainwater harvesting has been introduced. Around 2000 litres of rainwater is harvested and the water is used for water organic farming which is being carried out of the roof top of a commercial market. Also, the water I the Sewage Treatment plants in Sector V in Salt Lake and New Town is recycled and this water is used for watering roadside plants and tall tree gardens.last_img read more

Big Nose Kate – Doc Hollidays Rough and Tumble Lover who Broke

0 Comments

first_imgShe is remembered in history as Doc Holliday’s on-and-off girlfriend with the big nose. But Big Nose Kate was much more than that. She showed true grit when it came to situations like saving her life or the life of her beloved man.She was born Mary Katherine Horony in 1850, in Hungary. Her father was a physician who in 1862 was appointed as the personal surgeon of Emperor Maximilian of Mexico.So, all the family moved to Mexico. Unfortunately, only three years after leaving Hungary, Maximilian’s rule collapsed and the Horony family left Mexico and settled in Davenport, Iowa.Kate Horony (left) and younger sister Wilhelmina circa 1865, at the time they were orphaned. Kate is about 15 years old.As if there was some curse on the family, in 1865, the same year that they moved to the U.S., Katherine’s mother passed away. Only two months later, her father died. Kate became orphan at the age of fourteen and along with her siblings was placed in a foster home.Whatever happened in that foster home remains unknown, but Kate ran away to St. Louis with the help of a ship’s captain who became her friend. She went to a convent school and later married Silas Melvin, a dentist with whom she had a child.Big Nose Kate at about age 50, photo circa 1900.Tragedy appeared as an entwined part of Kate’s life. She lost both her husband and child to yellow fever. In 1869, Kate started working for madam Blanch Tribole in St. Louis, as a prostitute. By 1874, she was known as a “sporting woman” who worked in the “sporting house” of Nellie “Bessie” Earp, James Earp’s wife, in Dodge City, Kansas.Kate was independent, stubborn, and tough. She always said that she was in the “sporting business” because she liked it, belonging to no man, nor to any house.It is most likely that it was during her time in Dodge City that she met Wyatt Earp, although Kate later claimed that the two met in Fort Griffin, Texas. There were many speculations that Kate and Wyatt had a romantic relationship.Wyatt Earp, 1870s.Whether true or false, their acquaintance didn’t matter much after Kate met Doc Holliday, the love of her life, in Fort Griffin in 1875. He was a dentist and a gambler who worked in Shanssey’s Saloon, dealing cards. Kate was an attractive dance hall girl and a prostitute, known for her big nose. However, their temperaments somehow matched perfectly and they fell madly in love with each other.Their relationship was always on-and-off; they were frequently living together and separating, leaving each other and then longing. Their relationship might have inspired fiction.Doc Holliday, as he appeared in the early 1880s.In 1877, Big Nose Kate saved Doc’s life in a movie-like scenario. He was arrested for killing a bully during a card game. Although it was self-defense, Doc was imprisoned and the town seemed keen on hanging him.But Kate intervened. She set the whole jail on fire and while everyone’s attention was on putting it off, she threatened a jailer with a gun to release Doc from his cell. They escaped to Dodge City together, but couldn’t last together long and split up.Big Nose Kate Horony.After three years, in 1880, they reunited in Tombstone. But after the Gunfight at the OK Corral in 1881, they split up again because Doc was worried about Kate’s safety. She moved to Globe, Arizona, where she ran a boarding house.Later, she moved to Colorado, where Doc spent his last years before succumbing to tuberculosis in 1887.Gravesite of “Big Nose Kate.” Photo by MB CC BY-SA 4.0It is unknown how much or whether they had any contact at all during this time. But it was only after Doc’s death that Kate married another man, in 1888, a blacksmith named George M. Cummings.A year of marriage was too overwhelming for Kate and she left her husband. She traveled around Arizona living in various towns. Eventually, she met a man with whom she lived until his death in 1930.Read another story from us: She Wanted Her Men to Suffer – History’s Most Sadistic CourtesanIn 1931, she wrote to George W.P. Hunt, Arizona Governor, asking to be admitted in the Arizona Pioneer Home. She was granted admission and she died in the home on 2 November 2, 1940, only five days shy of her 90th birthday.last_img read more

Stein’s scoop only confirmed what Colin has said since the trade demand went public. While many in the media said Pop would never deal Leonard to a conference rival, Colin has maintained that Leonard and his team have played their hand perfectly by demanding a trade to one specific team. With only one year remaining on his contract, Leonard has eliminated the possibility of a deal with any other teams who wouldn’t have any shot to sign him to a long term deal.While some in the past – see Dwight Howard and Paul George – have bungled their attempted exits from the team that drafted them, Leonard’s plot is the blueprint of how to handle the situation.last_img read more

Internet Activists Plan Day of Action to Protest Mass Surveillance

0 Comments

first_imgJanuary 13, 2014 3 min read Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now » Opinions expressed by Entrepreneur contributors are their own. The internet activists that came out to defeat the SOPA and PIPA censorship bills two years ago are once again mobilizing to protect our digital freedoms–this time from the state’s mass surveillance apparatus.Members of the Electronic Frontier Foundation, Demand Progress and other digital rights activists are calling for a “day of action” on Feb. 11 when they hope to rouse the internet community into collectively speaking out against the NSA and the government’s other intrusive surveillance tactics.Since the scope and breadth of the nation’s surveillance program was revealed by documents leaked by former security contractor Edward Snowden last summer, other reports about the NSA’s surveillance methods have followed, including one that alleges the agency placed spyware on consumer electronics made by Microsoft, Cisco and other major brands.Related: Judge Says NSA Phone Surveillance Is ConstitutionalPresident Obama has said he is considering changes to the program, including more privacy protections for more citizens and reforms to how the agency collects and keeps phone data. Those changes are expected to be announced in a press conference on Friday, just over three weeks before the digital rights groups’ planned collective action.”We haven’t yet seen the Internet rise in a coordinated action from the threat of surveillance, and that’s exactly what we’re hoping to trigger,” organizer, activist and entrepreneur Sina Khanifar says. “Without action, we’ve seen very little movement in Congress: the most promising bill yet, the USA Freedom Act, was introduced over a month ago and isn’t moving in a meaningful way.”Even with the President’s modest proposal, real reform will almost certainly take an act of Congress. Just last month a federal judge in New York rejected a challenge to the phone data collection program brought by the ACLU, saying that there was no evidence that the information had been misusedRelated: Can This Company Save You From the NSA’s Prying Eyes?”We need to send a message to our legislators that we won’t let the Internet be turned into a tool for mass surveillance. We need to push them to have the courage to support comprehensive reform, Boing Boing co-editor Cory Doctorow wrote in an open letter to Hacker News. “We’d like to ask you to step up once again in defense of a free, open and secure Internet.”In a Reddit IAmA, Doctorow, Brian Knappenberger and Peter Ekersley of EFF and David Segal of Demand Progress explained that in addition to the serious cause, the protest was being organized in honor of Aaron Swartz, a Reddit alumni and activist who founded Watchdog.net.”By planning a day of action on February 11th, we hope to rally both technology companies and everyday users to speak out and tell Congress that they expect action,” Khanifar added.Related: Tech Giants Form Group to Pressure U.S. Over Surveillance Growing a business sometimes requires thinking outside the box.last_img read more

Enforcing Your Right to Be Forgotten May Get You Remembered

0 Comments

first_img 6 min read Whoever recently succeeded in removing this 2002 New York Times story from his Google.co.uk search results may now need to file a new request with Google: “Please remove links to last week’s Times story reporting on my successful removal of that 2002 story from my search results.”The individual’s predicament illustrates some recurring challenges that have arisen as European authorities enforce, and Google complies with, a ruling of the Court of Justice of the European Union last May, which found that search engines must sometimes remove links that violate an individual’s “right to be forgotten.”Privacy rights in Europe are considered sufficiently fundamental that they can sometimes outweigh rights to free speech in ways that would not be possible in the U.S., where the First Amendment almost always trumps. The European court found that Google had an obligation to remove links to online versions of two 1998 newspaper articles about Mario Costeja González, a Spaniard who once faced attachment proceedings stemming from a debt. The articles had accurately reported on those proceedings, but since Costeja later cleared up the problem, the court felt that Internet users’ residual interest in the matter were outweighed by his privacy rights. (The ruling only affects the search engine’s links pointing to the newspaper articles; the court declined to require the newspaper to remove the articles themselves.) The full ruling is here, and a court press release summarizing it is here.The Costeja decision requires search engines to balance the “legitimate interest of Internet users” in obtaining accurate information against the “fundamental rights” of individuals who file complaints like Costeja’s. In the event Google declines to remove a link, the complainant can appeal to the Data Protection Authority (DPA) of his European Union country.Google began complying with the ruling almost immediately, although it has interpreted that ruling as applying only to complaints lodged by Europeans (usually meaning residents of those countries) and only to links that appear on Google sites tailored to European countries, for instance, google.co.uk, google.fr, google.it, or google.de. It does not remove links from its U.S. site, Google.com, even when that site is accessed from Europe—a bone of contention with DPAs.Another source of aggravation for DPAs is that when Google removes a link, it informs the affected site of that fact. (It does not identify the complainant who requested the removal.) Accordingly, Google informed the New York Times last month that it was removing links to five specified Times articles.DPAs object to Google informing affected publishers in this fashion, because it enables them to do precisely what the Times did, which is publish an article about the link removals—which runs the risk of reminding the world about the very people who were seeking to be forgotten.In fairness, the Times reacted in a very measured way. If it wanted to be ornery—as some web publishers may—it could have identified all five articles. Instead, the story, by Noam Cohen and Mark Scott, alluded only generically to three of them, which it judged to be “intensely personal—two wedding announcements from years ago and a brief paid death notice from 2001.”On the other hand, the article did fully identify the other two articles. That, too, seems reasonable under the circumstances, since those details have considerable news value: they provide some of the only concrete clues we are getting at the moment as to how the right to be forgotten is being administered in practice. DPAs do not release any specifics about requests being made or granted—which would defeat the purpose of the requests—and the search engines, too, are being circumspect, lest they be seen as flouting the court.One of the articles to which search links were being suppressed, the Times explained, had reported in 2002 on a federal court ruling shutting down certain web sites in response to a Federal Trade Commission suit. The sites had sold $1 million worth of unusable Web addresses, the judge found. In last week’s article the Times then re-identified the two individuals whom the FTC had claimed controlled the sites, who had both been named in the 2002 article and were both said to be from London.If you type either of those individuals’ names into google.co.uk now, and look for news stories, you won’t get the 2002 Times story—at least I didn’t—but you will get last week’s story. You’ll also get a notice—and these also anger the DPAs—saying, “Some results may have been removed under data protection law in Europe. Learn more.”Since Google only takes down specific links that complainants object to, whoever objected to the 2002 story about the FTC case will have to file a new request objecting to last week’s story if he wants to try to eliminate the brand new reminder of the 12-year-old events he hoped would be forgotten.Why does Google notify web publishers when it removes links to some of their pages? Last July it provided this explanation to a group composed of all the European DPAs: “The notice … both ensures transparency and makes corrections possible when a removal process proves to be a mistake. We have received information from webmasters that has caused us to reevaluate removals and reinstate search results. Such feedback … enables us to conduct a more balanced weighing of rights, thereby improving our decision-making process and the outcome for search users and webmasters.”Google also notes that it adds the warning, to the effect that results “may have been removed,” to all non-celebrity name inquiries in Europe, so as not to single out those who’ve filed privacy petitions.The other Times article to which links were removed last month was also newsworthy, though mainly because it posed such a puzzle as to who would have ever gone to the trouble to suppress a link to it. The story in question was an amusing description of an acrobatic Off-Broadway show by the avant garde troupe De la Guarda, which featured “no seats, no plot, [and] no dialogue.”According to a Google spokesperson, as of mid-September it had received 135,000 requests to remove links to 470,000 internet addresses. He said the company isn’t currently publishing the number of removals, but as of late July Google told to the DPAs that links to 53% of the addresses identified in removal petitions had been removed.

5 Vital Considerations When Choosing Your Web Hosting Service

0 Comments

first_img Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global March 8, 2016 Let’s say your small business has an amazing product, your sales and customer service teams are exemplary, and you have powerful marketing that drives customers to your website. Despite all that, without a reliable web host to deliver a stellar online retail experience, people are just a click away from supporting your competitors. Even major corporations aren’t immune to challenging website issues. As CNBC reports, during Cyber Monday in 2015, Target’s website crashed, resulting in not only loss of sales, but in negative sentiment spread through social media.In 2018, worldwide retail sales will reach more than $28 trillion so it’s vital your business has a strong web strategy. It all begins with a website that functions correctly, which requires a stable Web host to guarantee very little downtime and a pleasurable user experience. Whether you’re launching a brand-new site or sprucing up an existing one, here are five features to keep in mind when searching for a Web host for your small business.1. Backup.You can’t have security without stable backup solutions. If your website does get attacked, you’ll want to make sure all your site content is backed up and easily accessible so you can get back up and running again quickly.Pro-tip: Try one-click off-site backup because it allows your data to get back online immediately. This should apply to both backup of data you input, as well as the backup of your Web host’s data in case something happens to its server.Related: 10 Options for Hosting Your Startup Website2. Security.Security should be at top of your mind when searching for a Web host since cyberattacks and malware threats can cause your site to crash, or put your customers’ private information at risk.When choosing a Web host, search for one that uses encryption technology between the user and the server, or between the Web host server and your business server. This ensures communications are encrypted and protected from hackers looking to obtain data.Pro-tip: Inquire about password storage — you’ll generally want your Web host to avoid storing passwords in plain text format.Related: How This Company Creates Instant Websites3. Analytics.When you’re searching for a Web host, learn about the built-in analytics it offers. Analytics can help drive your marketing and content strategy. It should also be updated in real time and easily accessible.You’ll also want to work with a Web host that makes it easy for you to integrate changes to your website. Search for one that allows for simple and straightforward login capabilities, both to make updates to content and to access features such as email.Pro-tip: Look for a Web host that features an easy-to-use control panel that allows you to not only access and edit any aspect of your website, but one that allows you to use search engine optimization tools.Related: GoDaddy’s IPO Could Value the Company at Up to $2.87 Billion4. Customer support.The Web never sleeps, and neither should your Web host customer support team. Around the clock support is essential, especially for businesses with Web visitors from around the globe. Pick a company with qualified customer service agents available to answer your questions at any time, in the language you speak.Pro-tip: Ask about typical wait times when calling support on the phone, and about chat and email support capabilities.5. ScalabilityIf you’re hoping your website leads to more business, you’ll want a Web host that can grow along with you and not crash as you grow. Ask a potential Web host what their uptime guarantee is. The closer you get to 99.9 percent uptime, the better.Pro-tip: A substantial uptime guarantee comes from reliable server capability and support, so look for a host that’s heavily endorsed by reputable customers.Also, be wary of shared hosting, which means your website will be on a server with many other sites. It can negatively affect your site if another website on the shared host is troubled in some way. It can also impact your website speed, which affects customer satisfaction. If you do go with a shared host, make sure the host has the ability to grow with you. Also evaluate any potential cost increases based on growth.Putting a website online can be simple, but it will only be successful if your Web host provides the relationship your small business deserves. Get to know your host and how they can benefit your business before locking down a partnership. Opinions expressed by Entrepreneur contributors are their own.
