In an age of computers, gadgets, gizmos, cell phones, and electronics everyone wants to be the first to produce, own, or buy the latest technology. Many solutions exist about how best to back up your data: Go with what suits you most but remember to also protect your computer from petty thieves. If you opt for local backup, make sure your storage is quite secure, otherwise you may want to entrust your data with cloud services. There has been a great deal of talk lately (from people with a variety of political points of view) about the prevalence and dangers of fake online news stories. This issue, however, is nothing new. For as long as there has been an internet, it has been common knowledge that much of what we come across online cannot be trusted. – Stabilitas, Linux sangat luar biasa stabil, jika dikonfigurasi dengan benar, system linux akan hidup terus menerus hingga hardwarenya tidak memadai (rusak), lain dengan windows yang memerlukan reboot berkala untuk menjaga stabilitas. Salah satu yang mendasari stabilitas ini adalah penomoran versi dari shared libraries, kebanyakan aplikasi windows menginstall versi-versi baru dari dynamic link libraries (DLL), yang mengakibatkan aplikasi lain yang menimpa versi lain dari DLL tersebut tidak berfungsi dengan semestinya. Linux juga mewarisi tradisi UNIX dengan mendukung adanya file permission (izin file), yang dapat mencegah pengubahan atau penghapusan file tanpa izin dari pemiliknya, karena itu, virus pada dasarnya tidak dikenal di dunia linux. I’m keeping my landline and I don’t own a cell phone. I worked as a tech support person for a cable company. I know how easy it is for those phones to go down versus keeping a reliable landline. One of Thomas Edison’s main rivals was George Westinghouse Jr., a pioneer of the electrical industry. In 1886 he founded Westinghouse Electric and Manufacturing Company to pursue the technology of alternating current (AC). An alternating current power system allowed voltages to be “stepped up” by a transformer for distribution, which reduced power losses, and then “stepped down” by a transformer for consumer use. He thought that Edison’s power network based on low-voltage direct current was too inefficient to be scaled up to a large size. In 1885 Westinghouse purchased power transformers developed by Lucien Gaulard and John Dixon Gibbs. Transformers were not a new invention, however this design was one of the first that was able to handle large amounts of power, yet was still easily manufactured. Using these transformers and a Siemens alternating current generator, he began experimenting with alternating current networks. Westinghouse worked to perfect the transformer design and build a practical alternating current power network with the help of William Stanley and Franklin Leonard Pope. In 1886 Westinghouse and Stanley installed the first multiple-voltage alternating current power system. The network was driven by a hydropower generator that produced 500 volts. The voltage was stepped up to 3,000 volts for distribution, and then stepped back down to 100 volts to power electric lights. This device made it possible to spread electric service over a wide area and allowed for the availability of alternating current at different voltages, forming the basis of modern electrical power distribution. Over the next year 30 more alternating current lighting systems were installed, but the method was limited because they lacked an efficient metering system and an alternating current electric motor. In 1888, Westinghouse and his engineer Oliver Shallenberger created a power meter that would be more effective and the same basic meter technology remains in use today.

N2 – In a mobile cloud computing system, lightweight wireless communication devices extend cloud services into the sensing domain. A common mobile cloud secure data service is to inquiry the data from sensing devices. The data can be collected from multiple requesters, which may drain out the power of sensing devices quickly. Thus, an efficient data access control model is desired. To this end, we present a comprehensive security data inquiry framework for mobile cloud computing. Our solution focuses on the following two research directions: First, we present a novel Privacy Preserving Cipher Policy Attribute-Based Encryption (PP-CP-ABE) to protect sensing data. Using PP-CP-ABE, light-weight devices can securely outsource heavy encryption and decryption operations to cloud service providers, without revealing the data content. Second, we propose an Attribute Based Data Storage (ABDS) system as a cryptographic group-based access control mechanism. Our performance assessments demonstrate the security strength and efficiency of the presented solution in terms of computation, communication, and storage. On the other hand, a September 2015 meta-analysis published in the International Journal of Obesity found that artificial sweeteners could help lower body weight when used as a replacement for sugar. This makes sense, because the total calorie count of food goes down when you replace sugar with a lower-calorie option. In the corporate field, Technology News plays a pivotal role as it provides technical specifications on the trends and developments of different operating systems and applications. Information Technology (IT) experts comprise a large population of employers and with information on updated technology, organizations are aware about the different specifications of intricate system applications. It is also possible to get information on complex technologies like Linux, Unix and Windows Operating System.
Graphene is the basic structural component of charcoal, 3D graphite, 1D carbon nanotubes, 0D fullerneness, and other carbon allotropes (carbon substances; one of the forms of elemental carbon). This means that graphene provides access to materials of all dimensionalities. Graphene is also different from other materials in the sense that, it contains mass-less charge carriers that act very much like protons, the particles of light. In addition, because of being chiral (not coinciding exactly when superimposed, a non-matching or non-congruent mirror image of a molecule), graphene is a guinea pig for exploring new quantum mechanics principles (the mechanics of atoms and sub-atomic particles which do not behave the same way as classical physics which we studied in high school), and a basis for producing functional devices that do not rely on typical metals and semiconductors, hence there are many applications related to electricity and the search for tremendous structural strength (stronger than any form of steel). Consider that each hour, of every day, the sun supplies us with enough energy as the entire globe uses in a year! Yet, the United States only receives 6% of its energy from renewable resources. Solar power is an infinite resource, unlike goal, oil and gas. We don’t need to worry about running out of sunlight in our lifetime. There is an argument that mobile phone causes change in the structure of chemicals of cells. Also, they are accused of causing cancer. The radiation from the mobile phones has been villainized by those who warn that the excess usage of mobile phones can damage brain cells. The heat produced by the radiation from mobile phones has been found to change the chemical structure of chemicals synthesized in small organisms like worms. But many scientists are of opinion that the radiation cannot be harmful to human tissues. A recent report says that so far there is no evidence of any adverse effect by mobile phone radiations, but they added that new researches have to be conducted. A GFCI or RCD is a safety device designed to shut off power in the event of an electrical “leak.” These devices can save your life and should be fitted to all extension leads.
