Due to bundle of complaints and the incidents of battery explosion of Samsung Note 7, a big amount of airlines have banned Samsung Note 7 use in their flights. There are news that the replaced devices also have the same problem.

World Expo --- EXPO 2020 Dubai

World Expos

The Great Exhibition, held in London in 1851, inaugurated World Expos as the hallmark events of a world aspiring to strengthen its connections, celebrate its cultural diversity and marvel at its technological wonders.

Today, World Expos remain a key meeting point for the global community to share innovations and make progress on issues of international importance such as the global economy, sustainable development and improved quality of life for the world’s population.

Every five years, World Expos attract millions of visitors who explore and discover pavilions, exhibitions and cultural events staged by hundreds of participants including nations, international organisations and businesses.

Each World Expo is a catalyst for economic, cultural and social transformation and generates important legacies for the host city and nation. For instance, Shanghai 2010 World Expo helped transform a heavily industrial city-centre area into a thriving cultural and commercial district while also bringing its theme “Better City, Better Life” to the attention of 73 million people.

The next World Expo takes place in Milan, Italy, in 2015. The focus: “Feeding the Planet, Energy for Life”.

What is difference between lifi and wifi?

In wifi, modulated signal is radio wave where as life modulated signal is light. It is visible electromagnetic spectrum and has higher bandwidth than wifi but has Line of sight limitation.

  

LiFi, The Next Generation of Wifi : Its Send Data via Light

LiFi ilustration
A study produced a technology called Light Fidelity or LiFi promises faster transfer speeds than WiFi and LiFi likely to replace in the future.

WiFi or Wireless Fidelity ears are probably already familiar to computer users. WiFi is also often referred to as WLAN (Wireless Local Area Network) that uses radio waves to frekuensi2, 4GHz using the IEEE 802.11 standard.

Recently, researchers have developed UniversitasEdinburg wireless networks or wireless systems capable of producing speeds up to 130mbps transfer using light technology.

The technology called LiFi (LightFidelity) using LED (Light Emiting Diode) to transmit data kepenerima with changes in the intensity of light is so fast that he could not be seen by the human eye.

A physicist and a professor of German, Harald Haas through the projects of the company's Pure VLC smartlighting developed methods that allow light is used to transmit and receive data that can reach speeds up to 50 Mbps.

At present it must be admitted that the data transfer speed of Light Fidelity technology is not yet able to beat the speed of data transfer standard Wireles Fidelity last generation.

Harald Haas, adding that he and his team continue to strive to develop LiFi system in the laboratory to produce a unit speed up to gigabits per second.

As reported by ArsTechnica, LiFi has several advantages such as broad-spectrum transmission and 10,000 from the broader-based wireless fidelity radio waves. LiFi also capable of providing wireless connectivity at home or dikamar without fear of leakage signals.

What Is Lifi? Why we Use?

LiFi is a new way to establish wireless communication links using the Led lighting networks. The LiFi protocols are defined by the international standard IEEE 802.15 established since 2011 by the IEEE comity. This is the same comity that has defined previously the Ethernet 802.3 and WiFi 802.11 standards. For numerous specialists, LiFi is a major breakthrough technology for the mobile Internet community and for the connected objects domain.
After more than 4 years of scientific research at the University of Versailles, OLEDCOMM is the first European company that start to commercialize LiFi communication solutions a worldwide level.
When the lighting networks become wireless communication networks
The world of Lighting companies experiences a true revolution with the development of Led lighting devices. With reduced energy consumption and a longer liftime, Leds appear as a solution that cannot be overlooked to face up to the challenge of the CO2 emission reduction at the worldwide scale. The sale of Leds Lighting units knows an impressive increase these last years.
Ten times higher data rates compared to WiFi
Leds are different from the other kinds of lamps because they are semiconductors. This characteristic gives them the capability to switch-on and off within few nanoseconds or billionth of a second. Converted in terms of data rates, this corresponds to 1 Gbits/s. In order to compare, at best WiFi can reach 100 Mbits/s data rates and so 10 times lower. 
Worldwide Economic and Green Impact
Thanks to the LiFi technology, the 14 billion lamps in the world will become gradually green mobile internet masts that will permit to respond to the impressive increasing demand of mobile conectivity. Also, this will allow reducing the electromagnetic pollution generated by the numerous radio wave solutions developed until now. 

VMware Showcases Cloud Management Solutions at VMworld

In the IT industry there's always someone, somewhere holding a convention: most recently it was VMware (again) hosting its VMworld 2013 event, this time in Barcelona. And when it comes to conventions, there are few finer places in the world to hold one than the Catalan capital — home city of Pablo Picasso, Salvador Dali, Lionel Messi and delicious tapas.
It's against this splendid backdrop that VMware has made a raft of announcements about new and upgraded products to keep its customers happy. Virtually SpeakingThere's another backdrop too, according to Martin Klaus, VMware's Group Product Line Marketing Manager.
"The backdrop for our announcements is the emergence of public clouds like Amazon, software-as-a-service (SaaS) offerings like Salesforce.com, social media, and easy access to IT," Klaus says. "IT departments are looking to become brokers of services, and VMware is trying to facilitate that by evolving from a virtualization provider to a cloud management provider."
It's not surprising that this is the VMware line, given that Hyper-V, Xen and KVM all do a perfectly respectable job in the server virtualization hypervisor department. That means that plain vanilla server virtualization is now officially boring, as far as VMware is concerned. Software-defined data centers (SDDCs) and cloud management systems, on the other hand, are where the company believes the action is.
40 Ways to Make Your Data Center More Efficient
OK, so down to business. VMware made three main product announcements in Barcelona, and they are all about cloud management:
  1. Cloud Automation: VMware vCloud Automation Center 6.0 (upgrade)
  2. Cloud Operations: VMware vCenter Operations Management Suite 5.8 and VMware vCenter Log Insight 1.5 (upgrade)
  3. Cloud Business: VMware IT Business Management Suite 1.0 Standard Edition (new) , VMware IT Business Management Suite 8.0 Advanced and Enterprise (upgrade)
So what exactly is new? Here are some of the highlights:
vCloud Automation Center 6.0:
  • Self-service catalogs providing a centralized approval and entitlement mechanism for infrastructure, application and other types of IT services. Visibility into the cost of VMs and the utilization of shared resources across internal infrastructure and public IaaS is also provided.
  • Anything-as-a-Service (XaaS) capabilities promise to allow IT departments to create "any" IT service, such as storage-as-a-service or backup-as-a-service.
  • Support for vCloud Hybrid Service and Red Hat OpenStack has been added, as has back-end support for Amazon, Azure and Hyper-V as well as VMware's vSphere.
vCenter Operations 5.8
  • vCenter Operations' analytics have been extended to include the monitoring of Microsoft Exchange and Microsoft SQL Server, and also to provide visibility into more vendors' storage systems through three supported APIs.
  • The software additionally now provides broader unified management capabilities with support for Hyper-V and Amazon's AWS public cloud.
IT Business Management Suite 1 Standard Edition
This is a new product that's aimed at the infrastructure team rather than the CIO or CFO, according to Klaus. Its aim is to make it easier to compare the cost of providing a given application at a given QoS level when implemented in-house in a private cloud, or hosted on Amazon or Azure public clouds.
"It will auto-generate a rate card, taking into account all the costs for the QoS you need, so you can make an apples-to-apples comparison of your cost with public cloud providers'," says Klaus. He expects that it will show that public clouds provide far lower savings levels than many infrastructure team leaders may imagine.
The obvious omission here is of VMware public cloud providers in the comparison charts, and it's one that must be galling to them given their support for VMware technologies. But Klaus says that adding support for them is "on the roadmap" and will happen at some point in the future. "But Azure and Amazon is where the action is at the moment," Klaus adds.
And that just about wraps up the key product news, except to point out that they are announcements and not product launches — expect the new software to ship some time before the end of the year.
So for those lucky enough to be in Barcelona, it's back to the delicious tapas…

Twitter users make headlines as tweets 'turn everyone into reporters'

Twitter has transformed the media industry and turned ordinary members of the public into reporters, one of the social networking site's top bosses told a conference in the UAE capital on Wednesday.

Speaking at the Abu Dhabi Media Summit, Shailesh Rao, Twitter’s vice president in Asia Pacific, Latin America and emerging markets, said: “Traditionally, it was through mainstream media that people received information. Today it’s different and it seems like everyone is doing it. Tweets, or visualisation through tweets, inform people about what is happening.
“Everyone with a computer, smartphone or any other gadget can send tweets and pictures of what is going on across the globe.”

The social networking expert was giving a speech on how conversation media and Twitter play a major role in disseminating information.
“Twitter users have the power to dictate what stories spread through discussion, retweets and favourites,” he said adding that the reader is no longer a passive recipient of news but also participates in reporting or pursuing news deemed to be of interest. Mainstream media such as 7DAYS, according to Rao, can also use Twitter as a powerful tool to draw audiences to their news websites, using a tweet that includes links to stories with greater depth than a 140-character tweet could ever offer.
He noted that it is necessary for traditional media outlets to pay fresh attention to what content is successful, as well as providing new ways of measuring success to compete in the digital era.
