...the Top 50 Android apps, but the guide provides useful insight into what Verizon considers best-practice standards for the key criteria. mobiThinking acknowledges there are more key criteria to creating a quality app, in terms of usability, device compatibility, stability etc – and that’s true – but arguably, problems with battery consumption, data usage and security risks are some of the most important of all quality assurance (QA) criteria because: a) they are mostly hidden from consumers; b) they are more easily overlooked by developers; c) the consequences are far reaching. Bad apps affect the performance of the device, battery and network; inflate the phone bill; and most consumers blame the device, operator… anyone except the real culprits. If the user interface (UI) is rubbish or the app keeps crashing, there’s little doubt the app is to blame and users will happily broadcast their verdict in their app reviews. 1) Battery consumption Some mobile applications use a lot of energy, causing unnecessary drain on the (already heavily taxed) device battery. There are numerous reasons why this occurs and, where it is caused by bad, ignorant or devious development practices, it can and should be rectified. Causes of battery depletion include: • Apps that run without the user’s permission. Some applications start automatically when the handset is powered on or don’t go to sleep when the user stop using them. See the video review of Wakelock Detector below for examples of...

...1 INTRODUCTION Each of the past three centuries was dominated by a single new technology. The 18th century was the era of the great mechanical systems accompanying the Industrial Revolution. The 19th century was the age of the steam engine. During the 20th century, the key technology was information gathering, processing, and distribution. Among other developments, we saw the installation of worldwide telephone networks, the invention of radio and television, the birth and unprecedented growth of the computer industry, the launching of communication satellites, and, of course, the Internet. As a result of rapid technological progress, these areas are rapidly converging in the 21st century and the differences between collecting, transporting, storing, and processing information are quickly disappearing. Organizations with hundreds of offices spread over a wide geographical area routinely expect to be able to examine the current status of even their most remote outpost at the push of a button. As our ability to gather, process, and distribute information grows, the demand for ever more sophisticated information processing grows even faster. Although the computer industry is still young compared to other industries (e.g., automobiles and air transportation), computers have made spectacular progress in a short time. During the first two decades of their existence, computer systems were highly centralized, usually within a single large room. Not infrequently, this room had...

...------------------------------------------------- Techniques and terms[edit] All social engineering techniques are based on specific attributes of human decision-making known as cognitive biases.[3] These biases, sometimes called "bugs in the human hardware," are exploited in various combinations to create attack techniques, some of which are listed here: Pretexting[edit] Pretexting (adj. pretextual), also known in the UK as blagging or bohoing, is the act of creating and using an invented scenario (the pretext) to engage a targeted victim in a manner that increases the chance the victim will divulge information or perform actions that would be unlikely in ordinary circumstances.[4] An elaborate lie, it most often involves some prior research or setup and the use of this information for impersonation (e.g., date of birth, Social Security number, last bill amount) to establish legitimacy in the mind of the target.[5] This technique can be used to fool a business into disclosing customer information as well as by private investigators to obtain telephone records, utility records, banking records and other information directly from company service representatives. The information can then be used to establish even greater legitimacy under tougher questioning with a manager, e.g., to make account changes, get specific balances, etc. Pretexting can also be used to impersonate co-workers, police, bank, tax authorities, clergy, insurance investigators — or any other individual...

...U.S. Department of Justice Federal Bureau of Investigation 2012 The Strategic Information and Operations Center at FBI Headquarters is the 24/7 command post that monitors FBI operations and law enforcement activities around the globe. An FBI agent examines a potentially contaminated letter during a white powder training exercise. 2012 The FBI Story I A Message from FBI Director Robert S. Mueller, III For the FBI and its partners, 2012 was a year that reminded us once again of the seriousness of the security threats facing our nation. During the year, extremists plotted to attack—unsuccessfully, thanks to the work of our Joint Terrorism Task Forces—the U.S. Capitol, the New York Federal Reserve Bank, and other landmarks on U.S. soil. Tragically, on the 11th anniversary of 9/11, a hateful attack in Benghazi took the lives of the U.S. Ambassador to Libya and three other Americans. In the cyber realm, a rising tide of hackers took electronic aim at global cyber infrastructure, causing untold damages. High-dollar white-collar crimes of all kinds also continued to siphon significant sums from the pocketbooks of consumers. And in Newtown, Connecticut, 20 young children and six adults lost their lives in one of the worst mass shootings in American history, ending a year of violence that saw similar tragedies around the country. Working with its colleagues around the globe, the FBI is committed to taking a leadership role in protecting the nation. As you can see from...

Rajiv Mukherjee, Engineers India Ltd. T hermal design of shell-and-tube heat exchangers (STHEs) is done by sophisticated computer software. However, a good understanding of the underlying principles of exchanger design is needed to use this software effectively. This article explains the basics of exchanger thermal design, covering such topics as: STHE components; classification of STHEs according to construction and according to service; data needed for thermal design; tubeside design; shellside design, including tube layout, baffling, and shellside pressure drop; and mean temperature difference. The basic equations for tubeside and shellside heat transfer and pressure drop are wellknown; here we focus on the application of these correlations for the optimum design of heat exchangers. A followup article on advanced topics in shell-and-tube heat exchanger design, such as allocation of shellside and tubeside fluids, use of multiple shells, overdesign, and fouling, is scheduled to appear in the next issue. • baffles; and • nozzles.

...INFORMATION TECHNOLOGY FOUNDATION 1 Compiled By: RONKY F. DOH (aka: ronky biggy diggy daddy igp) FU DAME TALS OF COMPUTERS We are living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded computers may be inside your household appliances, the video cassette recorder, the automobile, planes, trains, power plants, water purification plants, calculators, and even inside a few toys. These embedded computers are very small. They affect our lives each day. Why, even modern traffic lights operate with computers. They are all around us. Think of additional ways in which computers affect our lives each day. Every organization somehow use(s) a computer to run the organization. Some of the places are hospitals, schools, fire department, banks, stores or supermarkets, stock exchange, police department, insurance companies, transport companies, and government agencies etc. What is a computer? A computer is many things to many people, depending on what it is being used for. At one time the computer can be a machine which processes the payroll, then it can be a machine which tabulates...
