Last week Public Health England said they are working on a new tool to tell patients their brain age, as part of the fight against dementia. As far as structure of your grey matter is concerned, once you’re past the mid-twenties, it’s downhill all the way - your brain begins to shrink. Structural decline is inevitable and an inescapable fact of life. If we lived to be 150 years old, we’d all eventually display signs of Age Related Cognitive Decline (ARCD) as a result of the natural processes of brain ageing. Being around that long would mean that at some point we would all have succumbed to the forgetfulness, distractedness and compromised problem solving that characterises ARCD. ARCD may be an inevitable thing in the long run but you’ll be pleased to hear that there are several things that you can start doing right now to help slow this process down. If not kept under control, a free radical is to the structure and fabric of your brain what a bull is to a china shop. Having gained access to your brain mainly through cigarette smoke, exhaust fumes and fatty foods, the best way of counteracting their damaging effects is simply by reducing intake of red meat and eating plenty of fresh fruit and vegetables – the oldest and still the best readily available sources of brain tissue protecting anti-oxidants. Anti-oxidants mop up the free radicals before they can cause any damage. So make sure you do your 5+ portions of fruit and veg a day for your brain’s sake. Take your brain for a walk A litre of blood passes through you brain every minute. This is just as well because there’s no space for storage in the brain so it must receive a constant supply of nutrients to keep it working properly. Any interruption to the flow of blood to a certain chunk of the brain can lead to Silent Cerebral Infarct at best or a full blown stroke at worst. Making sure that the pump that pumps all that blood – your heart – is in good working order is a good first step; regular exercise is the best way to keep the heart strong. It also helps to ensure that the blood vessels transporting the blood remain clear of obstructions - vital to allow that oxygen-packed, nutrient rich blood to reach every part of your brain, every minute of the day. Regular moderate to intense exercise is well known to keep brains functioning better for longer. And the most likely explanation is that by keeping moving, as opposed to spending most of the day sedentary, you keep your heart and brain’s blood vessels flexible so they can always deliver the goods where they’re needed most. Build cognitive reserve through neuroplasticity (get some hobbies) What sets your brain apart from today’s supercomputers is its ability to physically change to meet new challenges. By consistently challenging it with fresh mental activities, your brain will be continually forced to restructure, rewire and build new connections to cope with the new demands placed on it. There are four hobbies that the Einstein Ageing Study observed were associated with a delay in the onset of dementia. These activities, if carried out regularly, intensively and over long periods of time are thought to help build “Cognitive Reserve” – which appears to delay the transition of ARCD into dementia by several years: Learn a musical instrument Playing an instrument involves mani[CENSORED]tions of an object with various body parts (e.g. fingers, lungs and mouth for most wind instruments) to produce tightly coordinated and rhythmically precise sounds. Even reading the music involves decoding the marks on a piece of paper that denote the pitch, onset, duration and style of each note and holding the sequence in mind for long enough to execute the correct muscle movements. All whilst simultaneously listening to the sounds you produce yourself in relation to those produced by the other players in your band to establish that the desired overall effect is created. Great mental gymnastics! Play chess Chess requires potential moves of both players to be imagined and held in mind so that further moves can be thought through. Opportunities and pitfalls of each potential sequence of moves must be analysed to select the best strategy. The more moves in advance a person tries to plan, the harder the brain areas in their Frontal and Parietal Lobes that support working memory are pushed try to keep in mind where all the pieces would stand after each imagined move. Improving your working memory can also have a positive impact on fluid intelligence. So playing chess might even make you smarter too! Dancing Dancing is a quintessentially social event. Maintaining regular social contact with other people is known to have a powerful positive impact on mental health and wellbeing by making individuals feel connected to their community. Most of the dance styles in question require careful coordination of your own movements with those of your dance partner, which must all be synchronised to the musical beat. Physical contact triggers the release of oxytocin into the bloodstream. This neurohormone induces feelings of trust, comfort and a sense of belonging; boosting that sense of social connectedness and wellbeing. Reading Reading involves converting strings of letters into words, words into sentences and keeping the meaning of one sentence in mind in light of those preceding and following it. Images must be conjured up in the mind’s eye and sounds in the mind’s ear. Previous chapters of whatever book you happen to be reading must be brought back to mind in order to interpret new events and [CENSORED]ure possible scenarios must be imagined to anticipate likely outcomes. A dynamic impression of all the characters’ personalities is assembled whilst the trajectory of the plot unfolds. Whether you’re going to play an instrument, have a game of chess, get up and dance or enjoy a good book, the key to inspiring your brain to change is to do it regularly, intensely and over long periods. The great news is that these are all fun activities that anyone can do to ensure they maintain a healthy brain for as long as possible.

The Revolution in Egypt Five years ago, a revolution began in Egypt. On January 25, 2011, thousands of people flooded the streets to protest poverty and corruption. Within a month, President Hosni Mubarak had stepped down after 30 years of rule. Emine Gozde Sevim, a Turkish-born photographer based in New York, knew she had to get there. "I was watching the news constantly, and I just wondered about life and how people were living," she said. "I wanted to know what it means to be living and breathing when things are so unpredictable in the streets." She first traveled to Egypt in November 2011, just before parliamentary elections were about to begin. "It was a very humble approach, and I didn't have any idea for a project," she said. "I just wanted to go and breathe the air. It was as simple as that." She made multiple trips over the next two years, usually every couple of months. Her work from that time culminated in a book, "Embed in Egypt." Sevim's photos show the demonstrations, the raw emotions of the so-called Arab Spring. But they also show everyday life: people dancing, celebrating birthdays, enjoying amusement parks. "My first impression was how resilient people were," she said. "No matter how sort of iron was the fist, the people just kept resisting. ... Overall, there was this hope and belief." Things changed rapidly in the country. In June 2012, Mohamed Morsy was sworn in as the country's first democratically elected President. A little more than a year later, he was ousted in a military coup. Now, former Army chief Abdel Fattah el-Sisi is in charge after being elected President in June 2014. The volatility is why Sevim's book isn't in color. "That feeling that became Egypt for me for this period became something of the past very quickly. ... Black and white fit in for that," she said. Sevim hasn't been back to Egypt since the coup. She'd like to go back sometime soon, to see old friends and share her book. "The optimism, the joy that we see people having, hope being in the streets -- if that continues, it's internal," she said. "It's in very private spaces, and we can't really finger-point it. But life goes on. ... "The ideology that fueled people to go out there is still there. As long as they're alive, these ideologies will be alive."

Despite being quite intensive on a system’s memory and CPU in comparison to other browsers (like Opera or FireFox), Chrome has a reputation for being fast and stable above all. Unfortunately, this isn’t always the case. Chrome can occasionally encounter issues that cause it to crash on a regular basis, and fixing and diagnosing these issues can sometimes be difficult. In fact, for the past week before the writing of this article, I’ve had Chrome hitching and hanging on me in ways it hasn’t before on this computer. You won’t be the only person finding out how to handle Chrome crashes. Problematic Plugins – Like Flash Anyone that’s a longtime user of computers, not just Chrome, has had a problem with Adobe Flash Player at one point or another. Despite this being an infamous problem that’s gone on for years, Flash continues to cause issues on even the latest, greatest computers and operating systems. One way Flash can cause issues is if you have a double installation. In the past Flash could be installed as both a plugin on Chrome and a plugin for Windows – this would cause pages relying on Flash to have issues as well as the browsers as a whole. To check and make sure this isn’t the case, go to [chrome://plugins]. Your list of plugins should look like this. If you see more plugins that you don’t recognize, you may want to disable them. In addition, your Flash Player plugin should look like this. If it has (2 files) beside it or there are two entries, you’ll need to disable the Windows installation of Flash. If your problem with Chrome deals with pages that rely on Flash, this should fix your issue. Flash gets automatically updated with Chrome. To update Chrome, simply select “About Google Chrome” as seen in the image above to cue an update (if there isn’t one queued already) and restart your browser. Keeping Chrome updated is generally a good idea, too, even if Flash isn’t your problem. Faulty Extensions/Extension Installations Being a Chrome user means you’ve likely installed a lot of extensions over time. Using new extensions can potentially cause problems with your system, but it may not be the extension’s fault. Sometimes, the installation of an extension is the problem, and all you need to do is reinstall it. First, head to [chrome://extensions] and remove all extensions you don’t recognize or use. Once you’ve done that, take note of the ones you do use and uninstall them, too. Then, start running the browser again while taking note of hitches or crashes. Restart Chrome and your computer before reinstalling extensions, and go one at a time, just in case one of them is causing the issue. An easier way to do this would be to simply do a full removal of Chrome and start anew. When you re-install the browser, be sure Malware and Hardware Issues These issues can interfere with Chrome and can be quite a bit more difficult or time-consuming to fix. To handle malware issues, simply install and run Malwarebytes, available from their site. Running a scan with your pre-existing antivirus should be able to pick up whatever you’re missing, too. Otherwise, you may have a problem with system files. System files can be fixed with the Scannow command which you can learn more about here. Finally, you may just be having a hardware issue. Hardware issues, unfortunately, may require you to buy new hardware. In Chrome’s case, it should be new memory or a new hard drive. In my case, a clean reinstall of Chrome fixed the issues I was having with it. But what about you? Comment below and let us know what issues you’re having, if this guide helped you, and if you need more assistance.

VCs have avoided solar deals ever since Solyndra became a four-letter word. But while their attention has strayed, the industry has been on a tear. In 2010, U.S. solar installers hit a milestone of 1 GW per year. Five years later, they’re installing more than 1 GW per month. This tremendous growth has fed a swelling herd of solar unicorns po[CENSORED]ted by the likes of SolarCity, SunEdison, SunPower and more. Recently, the industry has been buffeted by a variety of tailwinds that should drive even faster expansion. The landmark Paris climate accord promises stronger regulatory support across the world. Concurrently, a group of billionaires led by Bill Gates announced the Breakthrough Energy Coalition to fund this roll out. And the U.S. Congress has extended the solar Investment Tax Credit (ITC), which has raised installation forecasts through 2020 by more than 50 percent. Add to this mix innovation in large-scale battery manufacturing and the [CENSORED]ure of distributed power generation looks bright indeed. It’s also creating an opportunity to build the first SaaS unicorn focused on distributed generation. As this industry grows, so does the need for software to improve efficiency and lower costs. “Soft costs,” like permitting, financing and customer acquisition, now represent roughly two-thirds of installed costs of residential deployments. As I’ve written about before, the best way to address such soft costs is with software. As an example, the manner in which solar developers identify, track and quote potential customers today is decades behind other industries. The leading solar players today use a “spit and glue” combination of Salesforce, homegrown code and Excel. It’s not shocking, therefore, that SolarCity’s customer acquisition costs have actually increased year over year, while installation costs have plummeted. Other industries have solved this problem with software tailored to the specific needs of industry users. In the pharmaceutical space, Veeva Systems (an Emergence portfolio company) built a customer relationship management (CRM) solution focused exclusively on solving customer acquisition problems in pharma. This vertical-specific solution improved sales productivity by an average of 66 percent. A similar tool for solar could marry building data with customer demographic information to make developers substantially more effective at closing deals. Solar needs a Veeva-like tool to accelerate the path to grid parity (the point at which solar electricity costs the same as average grid electricity and growth skyrockets). The good news is that a lot of folks are working to build this type of industry cloud application. The Department of Energy’s SunShot Catalyst program is funding a slew of early stage solar software companies. Powerhouse, a solar-focused accelerator, is incubating still more. And even the VCs have started to put money back into the sector, including Obvious Ventures’ recent $3.5 million funding of Sighten. This momentum has resulted in an exciting emerging ecosystem of SaaS providers focused on the distributed generation (DG) opportunity created by the rise of solar and energy storage. I’ve taken a stab at illustrating it below. I’m sure I’ve left folks off, and others will become miscategorized over time, so feel free to ping me with hate (or love?) email. This is a great start, but it’s still very early innings. Most of these companies are addressing important problems, but doing so as point solutions. To scale, they’ll need to expand beyond these entry points. Here’s my stab at a recipe for how to build the first solar/DG software unicorn. Focus on the top line: Start by solving a revenue problem (lead generation, CRM, proposal generation, etc.) versus a cost problem (error reduction, headcount reduction, etc.). It’s typically easier to get in the door with top-line-focused solutions, which is particularly important in industries that are relatively new to significant software spend. Sell by showing a clear return on investment (ROI) of increased sales relative to software spend. Build sticky, scalable software: Ensure you are used every day. Get to a point where an important employee group literally can’t do their job without your software. Further, it’s critically important to make sure this is true recurring software revenue and not professional services. I can’t emphasize this point enough. Do not become a software consulting firm doing custom builds. Write flexible software that customers can configure themselves. Layer the cake: Become a suite (expand products). Once you’re sticky in your core product and have become your customers’ most trusted technology provider, expand to solve other pain points. Veeva (the pharma-focused CRM I mentioned earlier) did this and built a nearly $4 billion company in the process. Expand to the incumbents: To capture the largest possible market size, it will be important to sell not just to today’s distributed generation players but to service the much larger utilities and independent power producers (IPPs) moving into the space — and which desperately need help selling to customers. Remember, these are the folks that have traditionally viewed their customers as “rate payers.” Expand modalities: Aim to be the software platform for each component of the distributed generation ecosystem (not just solar). Elon’s Gigafactory will only accelerate the coming of distributed storage, which will also require smart software to be sold and integrated effectively. To clear the mythical $1 billion valuation hurdle, today’s DG software players will need to expand their addressable market. The good news is that the overall solar industry is growing at a rapid clip, so the underlying trends are favorable. Getting a firm grasp on total potential market size is much more of an art than a science, but we can take the International Renewable Energy Agency’s (IRENA) global renewable energy employment forecasts as a basis for estimation. I’ve roughly assumed 15 percent of IRENA’s global employment forecast will be distributed generation professionals in roles like sales, finance and diligence. I’ve also assumed these professionals would buy SaaS software at $100/seat/month. This rough math gets us to an addressable market today of roughly $1 billion, scaling to $2.25 billion by 2020 and more than $3.5 billion by 2030. This would be a very exciting [CENSORED]ure for today’s incipient DG SaaS market. But I see a critical element missing from most of the current players, which will prevent this scale: enterprise SaaS talent. Most DG software executives today have tremendous experience in renewable energy, but they haven’t built and scaled large subscription-based software companies. Getting this talent in the door and pairing it with the solar pros is the only way I see companies scaling the mountain. Unfortunately, there’s not a lot of cross-pollination going on today. Solar folks tend to hang with solar folks and SaaS folks with SaaS folks, like they’re on different planets. We have to find a way to bridge these worlds to birth a unicorn. Thus, I’ll leave you with a challenge. If you’re on the solar side of things, open up LinkedIn and find your buddy or your buddy’s buddy who works at Salesforce, Box, etc. and offer to buy them a beer. If you’re on the SaaS side of things and interested in applying those skills to solving the biggest existential crisis of our time, drop me a note and I’ll be happy to connect you. Speeding the transition toward clean energy is our best bet at averting a catastrophic temperature increase. With a little interplanetary collaboration, we can build the software necessary to do it.

InfoWorld’s Technology of the Year Awards have celebrated the most important technology trends and the best IT products for 15 years now. Our awards have marked the rise of everything from 64-bit hardware to hardware virtualization, from Java servers to JavaScript servers, from XML Web services to REST APIs, and from Microsoft Word for Windows to Microsoft Word for iOS. We’ve seen a lot of changes. And the changes keep coming. Among this year’s winners, handpicked by InfoWorld editors and product reviewers, you’ll find a number of “traditional” names: Cisco, IBM, Microsoft, Red Hat. But you’ll also find the names of more open source projects than we’ve ever seen in the Technology of the Year winner’s circle, thanks to the huge role open source has come to play in software development, data center (and cloud) infrastructure, and big data analytics. Docker, Kubernetes, Mesos, Spark -- these are only a few of this year’s winners from the open source camp. In one way or another, each brings something new to the enterprise. Docker’s clever take on Linux containers was so po[CENSORED]r with developers, it became a standard even Microsoft sought fit to adopt. Kubernetes brings Google’s cloud-tested technology for container management to the rest of us, while Mesos -- the U.C. Berkeley AMPLab project that gave birth to Spark -- offers an elegant solution to cluster resource management. Meanwhile Spark, the fast-rising framework for doing distributed data processing in memory, has begun to usurp the role of Hadoop even among Hadoop vendors. That’s one of the superpowers of open source -- it makes it easy for everyone to rally around something new and better. Our winning products from Cisco and IBM may not have emerged from the open source “engine of innovation,” but they’re no less groundbreaking for that. IBM’s Watson Analytics -- a cloud-based machine learning service and everyone’s favorite “Jeopardy” contestant -- may set the bar for all predictive analytics tools. Cisco’s ACI, which takes an entirely new “policy model” approach to software-defined networking, can be driven entirely through an open API, using a Python SDK you can find on GitHub. It’s not unusual for Microsoft to lead the field in wins, and it happened again this year. You won’t find Windows 10 on our list (reasons here and here), but Microsoft Office is there, along with Visual Studio and Azure App Services. It really is a new Microsoft: Office is now available in solid, capable versions across Windows, OS X, iOS, and Android, while Visual Studio and Azure App Services support all manner of cross-platform development. It’s not only a Windows and .Net world anymore. As the 31 winners of the 2016 Technology of the Year Awards illustrate, it’s a world exploding with technology options for everyone: developers, IT pros, and the businesses and users they serve. For a close look at the best platforms, tools, apps, and cloud services on the business computing landscape, dive into our slideshow.

Some people takes games very seriously !

Wang Jing bought his first car, a Dodge Shadow, with $3,000 he scratched together working three part-time jobs in the U.S. as a postgraduate student in Florida. These days, the senior vice president in charge of Baidu Inc.’s autonomous driving efforts is far better paid. He’s also a man on a mission: To push China to the forefront of the coming driverless-car era. Baidu joins a crowded field. Google Inc., which started developing autonomous cars in 2009, has tested self-driving vehicles for more than 2 million miles and is considering making its self-driving car unit a stand-alone business under the Alphabet Inc. corporate umbrella later this year. Tesla Motors Inc. Chief Executive Officer Elon Musk has said his customers will be able to summon an electric car to drive autonomously from Los Angeles to New York within two years. General Motors Co. and Ford Motor Co. are also in hot pursuit of this emerging market. Undeterred, Wang, 51, sees a level playing field in the coming era of intelligent, autonomous cars--and one that China is capable of dominating. “Chinese carmakers started making cars 100 years after others and a lot of the core technology aren’t in Chinese hands, such as engines” said Wang. “With electric cars, with intelligent cars, the core technology shifts from the engine and gearbox to artificial intelligence and that’s an area where China is very close to the U.S., giving China the chance to catch up and seize leadership.” Robotic Brain Robin Li, Baidu’s co-founder and chief executive officer, has invested heavily into a subfield of artificial intelligence known as deep learning, which aims to improve search results and computing tasks by training computers to work more like the human brain. The company hired Andrew Ng, a renowned computer scientist and expert in robotics and machine learning as Baidu’s chief scientist in May 2014. Wang thinks the company can leverage its expertise in artificial intelligence, data mapping and Internet connectivity to excel in autonomous driving technology. Getting China into that game is a priority for Chinese President Xi Jinping, who sees digital technology as an opportunity for Chinese manufactures to become more innovative. At a global Internet forum last month, Xi made the point of visiting Baidu’s stand, where he listened to Baidu CEO Li discuss autonomous car development. It may take time for Chinese companies to scale up in this business, according to Cao He, an analyst with Minzu Securities in Beijing. "There is a long way ahead for Baidu and other companies trying to mass produce and sell autonomous driving cars," said Cao. "Given the wide diversity of road conditions from one place to another, it is unlikely for any company to come up with a sizable industry operation within five years." That said, there could be a lot of money at state. Baidu estimates that the Chinese market for car sales, buses, taxis and related transportation services is potentially worth more than $1.5 trillion a year in revenue. Getting a sliver of that could be a huge new revenue source for China’s biggest search engine company. By 2017, autonomous vehicles capable of traffic jam autopilot and autonomous valet parking should be on dealers’ lots, followed by highway autopilot with lane changing in 2018, according to Boston Consulting Group. Vehicles capable of urban autopilot could be ready in 2022, paving the way for fully autonomous vehicles by 2025, according to the consulting firm. “Chinese Internet companies like Baidu, flush with cash and confidence, are jostling for leadership in the holy trinity of the auto industry’s [CENSORED]ure: electrics, car sharing and - autonomous cars," said Michael Dunne, president of Dunne Automotive Ltd. in Hong Kong. “Google enjoys a huge lead in autonomy today. But don’t underestimate the Chinese will to compete." Wang thinks Baidu will have a competitive advantage over Google and other automakers that test their artificial intelligence in the U.S. because of local knowledge of road conditions. Chinese Roads “Many people who have returned after years of living abroad find they’re not used to driving in China, are afraid of driving in China because conditions are much more chaotic,” Wang said. “If you have a robot that’s trained on U.S. roads for instance, they’ll struggle to adapt to the way Chinese cross roads. Our robots are trained on Chinese roads.” Baidu, which is talking to city authorities in China, plans to have their autonomous cars running in 10 Chinese cities within three years. It is also poised to have a small group of people try out their vehicles this year in a closed environment such as a conference venue, said Wang. For the past three months, Baidu has been working with BYD Co., China’s leading electric car maker, to equip Baidu AutoBrain system, a software package that incorporates technologies for driving, observing the environment and decision-making to BYD’s vehicles, said Wang. Baidu may also join efforts with companies based in the U.S., according to Wang, who declined to name the candidates. Wang refers to the Baidu AutoBrain system as the core of the company’s autonomous-driving technology. Baidu’s self-developed highly automated driving maps record 3D road data and are accurate to within a few centimeters for vehicle positioning. The object recognition and environment perception technology enables the car to detect and follow other vehicles with high accuracy, recognize road lanes and accurately gauge distance and speed, according to Wang. There are all sorts of possibilities lying ahead for Baidu, said Wang. People may see Baidu-brand autonomous cars running on the streets one day, or they may find Baidu becoming a supplier of Baidu AutoBrain to assemblers. People may even see the day that a significant portion of Baidu’s profit coming from autonomous driving business. One thing is for sure, there is no turning back from the auto industry’s shift to driverless cars, according to Wang. "My grandchildren definitely won’t be requiring driving licenses."

Before, after, static, dynamic, not at all? The role of stretching in sport has become rather confused in recent years. The warm-up trend, certainly while I was growing up, was static stretching (holding a stretch for seconds or minutes) before playing sport, maybe a few leg swings and a quick canter around the oval. Stretching improves the flow of nutrients and blood to our muscles. It can also reduce soreness, and correct our posture and range of motion. It's also like self-massage: it feels good. Recent research has also explored the effect of stretching on fascia (the web of connective tissue that wraps around our muscles) and the preliminary results have been promising. Despite the benefits of general stretching, stretching before sport fell out of favour about 15 years ago, when studies found it can reduce performance in sport by as much as 20 per cent. It may also increase the risk of injury, it was said. So many people stopped stretching, or switched to a dynamic warm up (jogging or similar). A new review of a decade's worth of literature on the subject makes sense of the studies and offers a new set of recommendations. The Canadian-led research team found that indeed, static stretching before you perform explosive exercise can weaken you. Essentially, the stretching and softening loosens the muscles needed to catapult you with speed and power. The caveat was that this was only the case if each stretch lasted more than one minute and there was no dynamic warm up before the exercise. However, most people don't hold stretches that long, and when accompanied by a dynamic warm up, stretching does not seem to affect performance and may reduce the risk of muscle strain injuries. They noted that the confusion about stretching before sport may have resulted because many of the studies reviewed did not include a full warm up (including static and dynamic stretching) and the static stretches were held for a relatively long time. People going for a run or cycle can adequately warm up with a gentle jog or peddle, co-author of the review Malachy McHugh, the director of research at the Nicholas Institute of Sports Medicine and Athletic Trauma at New York's Lenox Hill Hospital, told the New York Times. For those performing more dynamic sports, like basketball or tennis, a full warm-up is beneficial. He added that stretching after workouts, or regular yoga classes, is good for everyone. "Hence, stretching in some form appears to be of greater benefit than cost [in terms of performance, range of motion, and injury] but the type of stretching chosen, and the make-up of the stretch routine, will depend on the context within which it is used," the review's authors concluded.

Brother ISIS is supported by 61 country's so do think it's hard to get Romanian weapons for them ? they get everything they want ! There will be also black weapons market in Romanian where you can buy the weapons. Black weapons market exist in every country. They need to be destroyed, they are a shame for Islam.

Three British travelers have been infected with the Zika virus, health officials revealed this week. "As of January 2016, three cases associated with travel to Colombia, Suriname and Guyana have been diagnosed in UK travelers," Public Health England said on its website. The government agency did not provide further details about the cases but added that the virus "does not occur naturally in the UK." Zika "is not spread directly from person to person," it said. The announcement came on the heels of last week's travel alert from the U.S. Centers for Disease Control and Prevention (CDC) recommending pregnant women postpone travel to Brazil, Colombia, El Salvador, French Guiana, Guatemala, Haiti, Honduras, Martinique, Mexico, Panama, Paraguay, Suriname, Venezuela and Puerto Rico. On Friday, the CDC expanded its travel warning to include Barbados, Bolivia, Ecuador, Guadeloupe, Saint Martin, Guyana, Cape Verde and Samoa. The recommendations also call for women who have traveled to these places during their pregnancy be screened and monitored for the virus if their visit took place while the virus was present in the country they visited. Pregnancy risks Zika virus is a mosquito borne disease. An individual becomes infected by the bite of an infected mosquito. Symptoms of the virus include fever, rash, joint pain and red eyes and can last from a few days to about a week. But 80% of individuals infected have no symptoms. The virus has been linked to an increase in cases of a rare neurological condition called microcephaly in babies. Microcephaly results in babies being born with abnormally small heads, and often serious, and sometimes deadly, developmental delays. t prompted the Salvadoran vice minister of health to tell women there not to get pregnant for two years, echoing similar warnings in Colombia and Jamaica. "We're recommending that women who may get pregnant plan their pregnancies and try to avoid getting pregnant this year and the next," Eduardo Espinoza told CNNEspanol Thursday. Women's rights groups have called on the government to lift El Salvador's total abortion ban in light of the news. "I think the Zika situation puts the total abortion ban into the national arena," said Astrid Valencia of Amnesty International. Since 1998, El Salvador has banned all abortion, even in cases of rape, incest, fetal deformation or where the mother's life is at stake. A worker fumigates against Zika virus carrying mosquitoes in Peru. No treatment There is no prevention or treatment. Travelers to dangerous areas are urged to prevent mosquito bites by using mosquito repellant and covering exposed skin. The aedis aegyptia mosquito, which transmits the disease, bites all day long, so individuals need to reapply that repellant and not let their guard down. Aedes albopictus mosquitoes, which are found throughout the U.S. and are known for transmitting dengue fever and chikungunya, may also transmit the virus, the CDC said Friday. However, mosquito bites and mother to unborn baby aren't the only ways this virus is transmitted. The new CDC report notes documented cases of infection from sexual transmission, blood transfusion and laboratory exposure. Stephen Higgs, president of the American Society of Tropical Medicine and Hygiene, told CNN that once a person is infected with the virus, it is likely that they will develop an immunity to [CENSORED]ure infection.

Our readers expressed overall dissatisfaction with Comcast's pricing, and after breaking down each plan's cost per Mb/s, it appears warranted that the company scored a sub-par two (2.11) stars on a scale of five. Some readers may have been influenced to give Comcast a low rating on pricing due to imposed data limits in certain regions. Others were quick to address the staggering price-to-performance ratio, with Comcast generally charging more money per megabit than alternative DSL providers for roughly the same speeds. This isn't as prevalent when you approach the top of Comcast's residential service tier, but the company's service plans do not become cheaper than comparable DSL offerings until they rise above most providers' maximum throughput, with 150 Mb/s at 52 cents per Mb/s. However, even 150 Mb/s customers were generally unhappy with their pricing, despite heavily praising Comcast's performance and reliability. "The price is too high, and will be even higher with the new data caps," said one reader, who scored Comcast above four stars in all areas except pricing. Once again, this debacle seems to boil down to availability. Many of our readers indicated that Comcast was the only high-speed Internet option in their area, and that having no alternative meant dealing with the company's regional data caps and high price points. Performance: 3 ½ Stars Last September, we launched a survey asking our readers to rate the price, performance, reliability and support of their Internet service provider (ISP). The response was massive, with more than 3,100 votes cast. We have already shared the reader survey results for AT&T. The next ISP we are going to examine garnered the most responses in our survey, with 710 users rating the company's high-speed cable Internet service. We had our readers rate the company's prices, performance, reliability and support on a scale of one to five stars, with one being the least satisfied and five being the most. We averaged each category's total score and rounded the results to the nearest one-quarter star. We also provided the mathematical average, allowing us to compare scores later. History First called American Cable Systems, Comcast was founded in 1963 with the purchase of a 1200-subscriber cable television system in Tupelo, Mississippi. The business reincorporated as Comcast Corp. in 1969, and held its first public stock offering in 1972. The company began to purchase other small communications entities, acquiring a larger customer base for its cable television services and increasing its market share. In 1997, Microsoft invested $1 billion in Comcast, allowing it to purchase larger companies like Prime Communications, Jones Intercable Inc. and Lenfest Communications Inc. These acquisitions netted Comcast another 2.3 million customers, further tightening its grip on the cable television market. Now a giant in the industry, the company even struck a deal with AT&T to acquire select cable systems in six different states in 2001, scoring almost another 600,000 subscribers. In 2002, Comcast launched its HDTV service and what we now recognize as its high-speed Internet services; the company boasted of 3.3 million high-speed data customers that year. The remainder of the decade was spent acquiring more of its competition and creating services that we still enjoy today, such as digital voice, video mail, DVR and On Demand. As cable Internet speeds began to increase, Comcast introduced its first 50 Mb/s subscriptions in 2009. And in 2010, the company rebranded its technology platforms, products and services as Xfinity, giving its Internet-based services a hip new name (and possibly stealing a line from Buzz Lightyear). In 2011, Comcast, along with General Electric, joined NBC Universal (which came into being after NBC and Universal merged in 2004), solidifying its spot as one of the most powerful communications companies on the planet. Last year, Comcast approved yet another insane acquisition, this time with rival Time Warner for a whopping $45.2 billion. This deal would have given Comcast roughly 40 percent of the total U.S. cable market, but the plans were abruptly dropped last April when public opposition and FCC reservations forced Comcast to abandon the effort. Today, Comcast offers its Xfinity High-Speed Internet service in virtually all regions of the country, with more than 22 million subscribers. It's no wonder that the company received the most responses in our reader survey. Technology Comcast offers high-speed Internet packages using coaxial broadband cable lines networked over a great distance. The signal is boosted via daisy-chained hubs, and unlike DSL technology, cable Internet customers typically don't experience performance degradation as they get farther away from the central hub. However, cable Internet subscribers use a shared hub to reach the Web, and can often experience reduced performance during peak times when many users are operating from the same hub. Cable Internet can reach higher peak speeds than the alternative, but generally costs more per Mb/s. Here’s a full chart of Comcast's primary service plans, speeds, prices and serviceable regions: Pricing: 2 Stars It was easy to find pricing information for Comcast since I am within one of its serviceable regions. Like most of the other ISPs, Comcast requires potential customers to input a valid address before revealing plans and costs, and often will only show you what is available in your area. Luckily, my quiet corner of the country offers every primary Internet service tier except the recently launched Extreme 505 Mb/s service. We decided to exclude this offering from our review due to its low availability and seemingly business-class contract terms (a three-year minimum with additional line installation fees). Asking an outlandish $400 per month also seems a bit out of reach for standard residential users. Still, it's nice to dream of how many seats you could host at your next LAN party with that level of performance. There were multiple bundles that brought the cost of certain Internet packages down to reasonable levels paired to television or broadband phone services. These plans offer promotional pricing for a contract term usually double the length of the discounted rate. For the sake of this review series, we only gathered data on stand-alone, non-promotional pricing. Fortunately, Comcast offered flat-rate pricing on all but one of its performance tiers, which currently requires a two-year contract while offering a one-year promotional rate. Here's a list of Comcast's complete cable Internet service offerings, with unbundled prices and contract terms. Incidentally, few readers complained about performance, with the majority of our readers providing positive feedback for Comcast's speedy broadband Internet services. With a score of 3 1/2 (3.53) stars out of five, Comcast earns the highest score so far in the performance category. Many readers praised Comcast's performance, with most rating it above three stars in our survey. Happy customers noted impressively fast speeds and often higher-than-advertised peak bandwidth. Some of our surveyed readers tied performance to pricing however, and even those who were pleased with performance still couldn't let that ratio slide. "The speeds were very fast," said one reader who rated performance above four stars, "but the pricing was awful." The few readers who did seem disappointed in Comcast's performance noted variable speeds, unstable connections and data caps as primary detractors. These community members mostly rated the company under three stars in this category. It's also interesting to note that our surveyed Comcast users voted performance as the least important factor in choosing an ISP -- which could suggest that high performance is just expected from a cable Internet provider at this point in time. Comcast seems to slightly exceed that standard, with an impressive performance score of 3 1/2 stars out of five in our survey. Reliability: 3 ¼ Stars Comcast also scored well in the reliability category, with our readers rating it at an impressive 3 1/4 (3.34) stars out of five. The most recent FCC study on ISP service reliability, Measuring Broadband America, seems to echo our survey responses. Despite the fact that this dated study does not reflect current Comcast offerings, we can still use it as a foundation for comparison. Generally, Comcast customers seem to enjoy higher-than-advertised speeds, with many of our surveyed readers praising its performance, uptime and reliability as well. "I get a lot more Mb/s than I pay for," said one surveyed Comcast customer, who rated the ISP at less than three stars in every category, despite this admission. Another commented, "Comcast's speeds and reliability are exceptional in my area, and my speeds have always been higher than advertised." The few Comcast users who rated the company's reliability at lower than three stars reported frequent and recurring outages, lower-than-advertised speeds and peak-time congestion as the primary factors. "It's fast most of the time, but reliability is an issue," said one of our readers. "It usually goes down at least multiple times a week, usually between 6pm and 11pm." For the most part, it seems Comcast offers a decently reliable Internet service for its customers, especially since it's the company's second-highest score in our survey. Service & Support: 2 Stars It's no secret that Comcast has a bad reputation for customer service, which our readers typically describe as "nonexistent" (or with other colorful adjectives that can't be repeated). This resulted in a score of two (2.13) stars out of five, which is on the low end of the spectrum in our survey. Many Comcast customers who participated seemed disappointed with customer support. One reader said, "when you do not have to deal with customer service, it is fantastic." Furthermore, JD Power's most recent customer service satisfaction study rated Comcast with three stars (out of five) or less in almost every regional market, placing the company among the lowest-ranked ISPs in customer satisfaction. Readers who were satisfied with customer support noted the company's friendly service, prompt remediation and effective tech support. "They have pretty good tech support and resolved the few issues I have had over the years quickly," said one reader, who seemed pleased on all levels. "High speeds. Good service. Great customer support," said another. Since the most important factor among readers considering an ISP is customer service, it cannot be a good sign that Comcast has received the least satisfactory score in this area. Overall, it cannot be a good sign that the most important factor among readers considering an ISP see Comcast with the least satisfactory score. Along with pricing, support was more important to our readers than performance or reliability, and not coincidentally, Comcast's scores are split straight down the middle. By that logic, Comcast's final grade in our ISP survey seems fitting. Overall: 2 ¾ Stars It should come as no surprise that Comcast's overall score was a slightly above average 2 3/4 (2.74) stars out of five. Despite more-than-respectable marks in performance and reliability, our readers could not forgive unsatisfactory pricing and support, which our surveyed Comcast users considered the two most important factors when choosing an ISP. Dropping the ball in two out of four categories obviously hurts the overall average. Judging by our survey, it seems that one of the largest issues facing Comcast is its perceived unapologetic attitude toward pricing policies and support. Offering bundled Internet packages with term lengths longer than the promotion rate is a sneaky thing to do (even though it's all in the fine print), and facing no competition in certain regions makes some users feel as though there's no choice but to pay higher prices. Conclusion Comcast's high-speed Xfinity Internet services received a very typical response in our reader survey, with participants giving almost identical testimony. According to many of our readers, the company's pricing and support are unsatisfactory, and despite its strong showing in performance and reliability, customers are less-than-thrilled with the two factors they consider most important. As a result, the company's overall score is low. Comcast's strengths lie in the very technology that brought it to the table: cable Internet service, which offers higher speeds than competing DSL providers. Readers seemed to think that Comcast's high speed and reliability weren't good trade-offs for its poorly structured pricing and customer support. Meanwhile, many who gave the ISP a higher-than-average score had the same issues as those who rated Comcast lower. The difference seems to be that the readers who gave Comcast a higher rating seemed complacent about its negatives, accepting them as "the cost of doing business." Here's a full rundown of our survey results for Comcast. Each category is labeled from one to four, with one being most important and four being the least when deciding on an ISP, according to the surveyed readers:

Becoming a computer technician is a great point of entry into the IT field, and computer hardware certifications will help demonstrate your knowledge and competency in maintaining computers, mobile devices, printers and more. These top 5 computer hardware certs can help you get your IT career off the ground. To a certain extent, the title of this article is something of a misnomer. In the interests of increased specificity, it might be more appropriate to add the words "general" or "mostly vendor-neutral," although we do include a credential from Apple in this list that focuses exclusively on Apple hardware. And in fact, it's possible to view some certifications from hardware vendors such as HP, Dell, Cisco, Juniper, Fortinet and so forth as hardware focused, at and beyond the entry level. Thus, as you peruse this guide, don't forget that there are lots of other options from which you can choose if you're interested in demonstrating your knowledge and abilities with some (or any) particular vendor's products and devices. There's another misnomer involved in calling these credentials hardware certifications, too -- namely, the idea that hardware can exist or operate independently of software (or vice versa). If you dig into the curriculum for any specific hardware-related certifications in any depth, you'll quickly realize that by and large software is in control of hardware nowadays. Software comes into play for installation, configuration, maintenance, troubleshooting and just about any other activity you can undertake with hardware. We don't want to misrepresent the focus and coverage of these certs, so it's important to understand that the hardware label simply indicates that devices are involved, not that hardware is ALL that's involved. Table 1 lists the results of an informal job search we conducted to see how frequently the featured certs appear in actual job postings. Keep in mind that these results are a snapshot in time and vary from day to day, depending on the needs of the employment market. However, they provide a good indication of the relative po[CENSORED]rity of each cert among employers. Table 1: Job Board Search Results * The Cisco CCT certification has three tracks; the job board search was performed using only "Cisco CCT" as the search term and not a specific track. A significant change from our 2015 article is the replacement of the Certified Wireless Technology Specialist (CWTS) with the Cisco Certified Technician (CCT), which is more relevant to computer hardware and appeared more often on job boards. Also, we received some feedback after polling the TechExams.net IT community forum that the Server+ isn't as po[CENSORED]r with IT professionals as in the past. However, we kept CompTIA's Server+ in the top 5 because it is still either recommended or required by HP, Intel, and other large organizations for their technicians. Also, when conducting online job searches, Server+ consistently surfaces in employer requirements. Thanks to Trevor Smith and the TechExams.net forum members for your input on computer hardware certs -- overall, it was very useful data!
