Walking Home Alone? Get Virtual Company With This App

If the thought of walking home alone worries you anytime, here comes a public safety mobile phone app that offers you a virtual company by allowing your friends or family members to a keep an watch over you.

The application named Companion, originally developed by students of University of Michigan in the US with the aim of providing lone travellers in the campus with peace of mind and help them avoid potentially dangerous situations, is now increasingly being used by people from across the world, media reports said.

One of the factors that have made the app popular is that anyone in your contact book can be your Companion and they do not even need to have the app installed.

The app which is free and available in both the App Store and Google Play, is being used by tens of thousands of people across the world, www.fox8live.com reported.

Companion utilises a phone's GPS, prompting users to enter their destination and share their route with select contacts, who are able to view a live map of the user's location and are notified if anything goes wrong.

The app will end the trip when the user safely arrives at his or her destination.
If the application senses that the planned route has been altered or that the trip is taking longer than expected, it will alert those selected friends unless the user confirms that everything is all right.
The user can end the trip at any time and also has the ability to use Companion to quickly alert law enforcement if the need arises.

Companion also has the potential to help public safety organisations enhance their strategies by providing real-time walking data that can be combined with historical walking patterns and a predictive engine to determine the best locations to station police officers.

"We see a lot of potential for Companion to be used in cities, across corporate campuses, or by parents who have kids going out with friends," one of the app developers Jake Wayne said.

New approach to Cross Platform Apps – Xamarin

Xamarin proposes a new methodology in building applications that takes the best of two existing methodologies and consolidate them : Use native code for portions of the code that need to get to particular hardware elements of the gadget and utilize Web dialects (HTML5, JavaScript, and CSS3) for the rest. It has a slight downfall of a bit on performance, but rest of the things are cool to check with.

Xamarin’s methodology is to let designers make UIs that are one of a kind to every platform, and after that make parts that can be reused effortlessly on another platform, utilizing the C# programming dialect.

Xamarin takes a special way; it regards the uniqueness of every platform and does not force developers to make applications that have resemblance on all platforms. Despite developers can use the native features over here. 

Xamarin in addition, not only the UI, has even an advantage of sharing code to cross-platform. For instance, your code for getting to Web services can be reused effortlessly on the iOS and Android platforms. 

Additionally, database code is likewise exceptionally compact. Xamarin’s methodology is to let developers make UI that are special to every platform, and after that make segments that can be reused effectively on another platform. 

Rather than utilizing individual languages for different platforms, a binding together language is required: C# was picked in light of the fact that it’s everything but difficult to learn, and it’s the dialect of decision for some .NET designers. Utilizing C# permits Xamarin to connect with a large number of potential designers.

Xamarin Studio IDE

The IDE assumes a vital part. A decent IDE empowers speeding up of any improvement exertion. Xamarin offers the Xamarin Studio, which is a world-class IDE that makes creating, troubleshooting, testing, and bundling applications a stroll in the recreation center.

Xamarin Supported Platforms

To build iOS applications, you require a Mac or a sensible copy. Xamarin offers three wide decisions:

Use Visual Studio on Windows. Utilizing Visual Studio, you can create iOS and Android applications natively on your Windows PC. In any case, the proviso here is that keeping in mind the end goal to test iOS applications, you have to have admittance to an organized Mac, which will give the fabricate and organization administrations. 

Use Xamarin Studio on Windows. Rather than Visual Studio, Xamarin gives its own IDE: Xamarin Studio. Like Visual Studio, Xamarin Studio gives a world-class advancement environment to quicken your improvement exertion. Like choice earlier, testing iOS applications bound access to an organized Mac. 

Use Xamarin Studio on a Mac. This is the best choice on the off chance that you are creating applications for both iOS and Android. Xamarin Studio’s close coordination with Xcode makes outlining and testing iOS applications simple.

Working with Xamarin

You compose your UI code for every particular platform one for Android and one for an iOS gadget. At that point compose business rationale that can be reused on both platforms.

Xamarin uncovered all APIs accessible in iOS and Android to your application as general C# class libraries. Moreover, your applications have admittance to a completely useful usage of the .NET runtime, which is packaged with your application so that your code executes with all the force of C# and .NET, for example, memory administration, and so on. When you are prepared to accumulate the application for every platform, Xamarin produces an ARM paired for iOS and exploits without a moment to spare assemblage for Android. As Xamarin applications are incorporated to native apps, they find themselves able to perform with no execution corruption that you may anticipate from cross-platform applications.

Google New Logo Released

First they changed their name, now they’ve changed their logo. Googleintroduced a new sans-serif and slightly toned-down four-colour logo on Tuesday in the biggest redesign since 1999.

Google said the new design would soon be seen across all its products. Google’s homepage introduced the redesign with an animation that wiped away the old logo and drew the new one.

“Google has changed a lot over the past 17 years – from the range of our products to the evolution of their look and feel. And today we’re changing things up once again,” the company said in a blogpost.

The company said the redesign was meant to reflect the way that people interact with Google products across many different platforms, apps and devices.

“It doesn’t simply tell you that you’re using Google, but also shows you how Google is working for you. For example, new elements like a colorful Google mic help you identify and interact with Google whether you’re talking, tapping or typing. Meanwhile, we’re bidding adieu to the little blue ‘g’ icon and replacing it with a four-color ‘G’ that matches the logo.”

The logo has undergone many, mainly small, changes in its history. The colours have changed, 3D letters have been flattened, and an exclamation point came and went in 1999.

The move comes just a month after a major restructuring of the company was unveiled. Google is now owned by Alphabet, a holding company created by founders Sergey Brin and Larry Page to separate their money-making search engine company from the loss-making, “moon shot” projects like robot cars, medical research and internet-delivering balloons.
