LARGEST AIRCRAFT IN THE WORLD

      We have lift-off. The world's largest aircraft has taken to the skies for the first time.The Airlander 10 spent nearly two hours in the air, having taken off from Cardington Airfield in Bedfordshire. During its flight, it reached 3,000 feet (914 meters) and performed a series of gentle turns all over a safe area.

      The aircraft is massive – as long as a football pitch and as tall as six double decker buses and capable of flying for up to five days. It was first developed for the US government as a long-rangesurveillance aircraft but was scrapped following cutbacks.

      Each one cost 25 million pounds and can carry heavier loads than jumbo jets while also producing less noise and emitting less pollution. The makers, Hybrid Air Vehicles, believe it‟s the future of aircraft, and that one day we'll be using them to get places.

      But we're a while away yet. The Airlander will need to clock up 200 hours‟ flying time before beingdeemed airworthy by aviation bodies. If it passes though, we can hope we'll all get some extra leg room.

Does an Email Hacking Software really Exist?

  With my experience of over 10 years in the field of ethical hacking and information security, all I can tell you is that there exists no such ready-made software program (as shown and advertised on many websites) that can break into the service provider’s database and hack email passwords. This is just a myth! This may seem a bit disappointing for many, but this is the fact. However, it is still possible to easily hack email passwords using some of the alternative programs and ways as discussed below:

  Working Ways to Hack an Email Password:

  Even though it is impossible to hack the database and instantly crack the email password, it is still possible to trick the users so that they give away the password by themselves. This can be done using a handful of methods like keylogging, social engineering or phishing. However, the easiest and most effective way is by using keyloggers.

  A keylogger is a small program that records each and every keystroke a user types on the keyboard of a specific computer. So when you install a keylogger on the computer from where the target person is likely to access his/her email, it is possible to capture the password. Though keyloggers are not designed to hack email passwords, they can still be used to accomplish the job. Here is a list of some of the interesting facts about keyloggers:

  EASY TO USE: A keylogger does not require any special skills. Anyone with basic computer knowledge should be able to use it.

  REMAINS UNDETECTED: A keylogger will remain undetected after installation and operates in a total stealth mode. So, you need not worry about being caught or traced back.

  REMOTE INSTALLATION: In addition to installation on a location computer, keyloggers also support remote installation. That means you can also install it even on those computers for which you do not have physical access.

      Donald Trump on Monday proposed collapsing the federal income tax rate from seven brackets down to three and called for allowing child-care expenses to be exempt from taxation in a speech allies hope will help the GOP presidential nominee turn the page on a tumultuous period some Republicans fear has severely damaged his campaign.

      Overall, Trump offered few new details behind his economic vision, which he unveiled as a candidate last year. One notable exception was his call to enable families to "fully deduct" child-care expenses from their taxes. Some such expenses are already deductible; experts say that the additional amounts will largely benefit middle- and upper middle-class families.

      On tax rates, business mogul said he would work with House Republicans and use the same three brackets they have proposed: 12 percent, 25 percent and 33 percent. Previously, Trump proposed tax brackets of 0 percent, 10 percent, 20 percent and 25 percent.

      "For many American workers, their tax rate will be zero," said Trump.

      The GOP nominee continued to leave large question marks about how he would pay for his plans and avoid ballooning the federal budget deficit. He included no new details on how he would limit the cost of his tax reform plan, which analysts have estimated would reduce federal revenues by as much as $10 trillion over a decade. His child-care expense plan would presumably raise that cost even further.

      Trump released a tax plan last year that would reduce the top income tax rate from 39.6 percent to 25 percent and bring down the top corporate rate from 35 percent to 15 percent. The plan would eliminate the estate tax and reduce tax rates to 10 percent for households earning $100,000 or less.

      Trump also did not spell out any federal spending cuts. In his remarks, Trump said he would offer more details in the coming weeks.

Using analysis, we can feel confident in the spatial patterns we see, and in the decisions that we make.

Putting your data on a map is an important first step for finding patterns and understanding trends. Here we’re looking at crimes that happened in San Francisco, about 37,000 of them. Looking at the points on a map, can you find the clusters or patterns in this point data? Can you decide where the police department should allocate its resources? Just looking at points on a map is often not enough to answer questions or make decisions using this kind of point data. That’s where the spatial analysis tools in ArcGIS come in. 

We’ve all seen heat maps on TV or in web application-beautiful maps that show high-density areas in bright red, and low-density areas in blue. These maps are used to visualize crime, disease, and a whole host of other types of data and information. These heat maps can be a great first step in a visual analysis of your data  they can also be very subjective. What does that mean? Well, the two heat maps shown below reflect the same San Francisco Crime data, and were created using the same tool. The only difference is the criteria that were used to decide what appears very dark (high density) and what appears very light (low density). These types of cartographic elements that we incorporate into our maps can have a huge impact on the story that the map tells. 

If the decisions that you’re trying to make as a result of your analyses are important, and they usually are, you’ll want to minimize subjectivity as much . A great way to minimize the subjectivity in your pattern analysis is to use a hot spot analysis, which incorporates a simple spatial statistic to determine if the patterns that you’re seeing are statistically significant or not. The hot spot map is shown here.

So what makes this type of map any less subjective than density-based heat maps? The very dark areas on hot spot maps are statistically significant clusters of high values (hot spots), and the very light areas are statistically significant clusters of low values (cold spots). What’s dark and what’s light is always based on statistical significance. Using hot spot analysis, we can feel confident in the spatial patterns that we see, and in the decisions that we make.(Adapted from: http://resources.arcgis.com/en/communities/analysis/017z00000015000000.htm
