Create Custom Windows 8 Pinned Start Screen Tile for your website

One interesting topic I’m going to discuss now! There are certain Tiles in Windows 8 Start Screen that we don’t even look at. So it’ll be logical to replace them with certain tiles like some browsers, websites or even your own website. E.g. You regularly use websites like Facebook or if you own a website, you regularly check it and update it.

So making one separate Tile for Windows 8 not only bags a front seat for you as well as makes you feel royal. So the following tutorial will help you to pin you website at the Windows 8 Start Screen. Okay, let me tell you another thing that this pinning procedure can also be accomplished using the Chrome but the Tiles look better when done with IE10 and presently Mozilla Firefox lacks this feature. Mozilla Firefox for Windows that will be launched in a short while may add this feature. We can hope for it. 8

Steps to create your own windows 8 Tile for your website

    1. Press Windows button to go to Start Screen and then click on Internet Explorer. Remember, you have to run Windows 8 IE 10 for this purpose and if you have Windows 8 IE 10, you don’t need to take much headache.

2. Type the address of the website for which you want to create the tile in the address bar and hit Enter. When the website is opened properly, take the cursor to the right bottom corner of the adress bar and check that a Pin Icon pops up in the black band. Click on it and select Pin To Start.

3. Now you’ll be asked to put description about your website or your application. Enter the text like here I entered MyWindows8.org: It’s all about Windows 8

You are done.

So by using this process we see that the Tile does not display the favicon.ico file of your website and the IE symbol will be there which somehow doesn’t look cool. So next, I’ll tell you the steps to give your website a elegant Tile Icon.



 

 

Your mobile website as a Windows Phone app

Introduction

Smartphone users love apps! But developing apps for multiple platforms can be time-consuming. A great alternative might be a mobile website. Web developers are using HTML5 to create webpages that are more powerful and feature-rich than ever before. But a website is not as customizable as an app. Let’s look at some advantages to each approach to reaching your audience.

Mobile website advantages

Many businesses and organizations have developed websites specifically to meet the demands of a society more and more accustomed to doing just about every task with mobile devices. Mobile websites:

·         Work across different mobile devices

·         Are easily upgradeable

·         Are searchable

·         Leverage web development skills

Dedicated app advantages

Apps can be powerful and fast, but they are tied to a specific platform. You have to write your app for each platform on which you want it to be available. Despite this, dedicated apps for Windows Phone can have features that tip the balance in their favor, like:

·         Pinning secondary Tiles to Start

·         Live Tiles

·         Local data on the phone itself

·         Speech recognition

Apps must also pass certification to be included in the Windows Phone Store. This gives users confidence when downloading an app from the Store, but it may add to your development cost.

The hybrid web app: The best of both worlds

There’s an ongoing debate between developers about mobile websites versus dedicated mobile apps. How about a solution that provides the best of both worlds? This is the hybrid web app, and Windows Phone has it.

A hybrid web app gives you a presence in the Windows Phone Store with much less effort than building an app from the ground up, and it adds features that can give it winning advantages over just a website.

With a hybrid web app you can:

·         Reuse the HTML, CSS, and JavaScript you’ve already created

·         Reduce development costs by leveraging investments across different platforms

·         Combine with C# to access the Windows Phone platform

For example, your app could support:

·         The ability to pin pages from your website directly to Start

·         The ability for users to share links to your webpages with their contacts on social networking websites

·         Speech recognition for searching your product catalog and other user commands

·         Wallet integration for storing loyalty card or payment card information

You could add many other features that you normally would find only in a dedicated Windows Phone app.

But, getting up and running quickly by leveraging the work you’ve already done creating your mobile website is where hybrid web apps really shine.

Think China is the Bo.1 Country for Haking ? Think Again

China has earned a reputation as the hacker capital of the world, but a new report shows the bulk of global cyber-attack activity has recently come from its smaller neighbor Indonesia.
Thirty-eight percent of cyber attacks originated in Indonesia during the second quarter of 2013, up from 21 percent in the first quarter, according to a report by security cloud platform Akamai. This spike helped push China off the hacking pedestal, with the world's most populous country accounting for 33 percent of attacks, down from 34 percent in the previous quarter. The U.S. rounded out the top three, generating 6.9 percent of cyber-attack traffic, a decrease from 8.3 percent.
Indonesia and China alone accounted for more than half of all cyber-attack activity during the quarter.

While it may seem like Indonesia came out of nowhere to take the lead (last year the country accounted for on average less than one percent of cyber crimes), hackers may be taking advantage of its increase in connection and weakening IT structure.
The country's average internet connection speed increased 125 percent in the second quarter from the same time last year. That, coupled with the fact the country isn't spending a whole lot of cash on its infrastructure,  may make the country a haven for cybercriminals.

In January, hacker group Anonymous Indonesia claimed responsibility for defacing 12 government websites with the tagline "No Army Can Stop an Idea" shown on the sites. In April, the country's defense minister Purnomo Yusgiantoro announced they were building a Cyber Defense Center to take on hackers. Microsoftalso felt the supposed wrath of Indonesia criminals (among others) when it put the kibosh on a cybercrime operation in June.
Akamai's findings are based on agents reporting log connection attempts, which the company defines as attack traffic. The company then can determine the top countries the hack attacks occur. One caveat to keep in mind: the IP address assigned to a particular country may not be the nation the attacker resides. So someone from China with an IP address associated with them, may be committing cyber attacks in France.

The Internet map

The map of the Internet

Like any other map, The Internet map is a scheme displaying objects’ relative position; but unlike real maps (e.g. the map of the Earth) or virtual maps (e.g. the map of Mordor), the objects shown on it are not aligned on a surface. Mathematically speaking, The Internet map is a bi-dimensional presentation of links between websites on the Internet. Every site is a circle on the map, and its size is determined by website traffic, the larger the amount of traffic, the bigger the circle. Users’ switching between websites forms links, and the stronger the link, the closer the websites tend to arrange themselves to each other.

Charges and springs

To draw an analogy from classical physics, one may say that websites are electrically charged bodies, while links between them are springs. Springs pull similar websites together, and the charge does not let the bodies adjoin and pushes websites apart if there is no link between them. Originally, all such electrified bodies (websites) are randomly scattered on the surface of the map. Springs are stretched, repulsion energy is high – the system is far from being at equilibrium. Then the websites start moving under the influence of the forces exerted and in a while come to a halt – forces of attraction now become equal to forces of repulsion, the system has reached its equilibrium. It is exactly that state that is shown on The Internet map.

Also, an analogy can be drawn from quantum physics. In this case, a website is a physical body with a finite mass, a single user is the mass quantum – the much-spoken-about, yet-to-be-found Higgs’ boson, whereas the act of user’s switching between sites is the gravitational quantum – the graviton, another hypothetical particle.

Anyway, the real algorithm of plotting The Internet map is quite far from the analogies given above. For those interested, the closest description of the mathematical model can be found in the research, and the engineering solution looks very similar to what has been described in . Google Maps engine has been used as the platform for displaying.

Semantic web

The map of the Internet is a photo shot of the global network as of end of 2011 (however, baloons show actual statistics from Alexa). It encompasses over 350 thousand websites from 196 countries and all domain zones. Information about more than 2 million links between the websites has joined some of them together into topical clusters. As one might have expected, the largest clusters are formed by national websites, i.e. sites belonging to one country. For the sake of convenience, all websites relative to a certain country carry the same color. For instance, the red zone at the top corresponds to Russian segment of the net, the yellow one on the left stands for the Chinese segment, the purple one on the right is Japanese, the large light-blue central one is the American segment, etc.

Importantly, clusters on the map are semantically charged, i.e. they join websites together according to their content. For example, a vast porno cluster can be seen between Brazil and Japan as well as a host of minor clusters uniting websites of the same field or similar purposes.

The Internet Phenomenon

The Internet global network is a phenomenon of technological civilization, and its exceptional complexity surpasses anything mankind has ever created. In essence, what we are dealing with here is a huge quantity of utterly unstructured information. The Internet map is an attempt to look into the hidden structure of the network, fathom its colossal scale, and examine that which is impossible to understand from the bare figures of statistics.
