What is Google Glass?

August 30, 2013

In the beginning of 2012, when rumors of Google’s ambitious project of wearable technology began doing rounds, few could believe that this was such a close reality. The intuitive spectacles, which have been developed with a vision of becoming the ubiquitous device of the coming decade, are all set to hit the market, and are available for developers to test for just $1500. So what exactly is Google Glass, and how can we expect it to change the world in the years to come? Put simply, Google Glass is an attempt to make data completely hands-free, enabling users to access the internet and other apps through voice commands.

This coming-of-age device wears less than an average frame of sunglasses, and can be worn discreetly, just like a regular pair of eyeglasses.  Each such frame has a camera, display, touchpad, microphone, and battery built into its chassis, enabling you to view the display within your field of vision, and perform all sorts of functions through voice commands- including taking pictures, sharing live streaming of events, recording videos, translating, searching the web, using navigation, etc.

Here’s a look at some of the tasks that Google Glass will be able to accomplish:

  • The embedded camera will be able to click pictures of things as you can see them from a first person’s perspective, eliminating the need for a viewfinder.
  • The microphone and touchpad on one side of the frame will enable you to select the function that you want to be performed from the screen that will appear in front of you. Google Glass will be able to interpret your commands through a brief gesture or voice command.
  • The device will also be capable to provide sound through bone-induction technology, which will be a lot less cumbersome than normal headphones.
  • Google’s voice-to-text functionality will enable you to pair your headset to your Android phone, and then view text messages on the display, and respond to them through the microphone. This feature will also make it possible to dictate emails.
  • You shall also be able to access a variety of other Google features, such as Google Maps, Google Hangout, Google Translate, etc. through the device.
  • In addition to these in-built features, there are expected to be a wide range of apps that users will be able to access through the headset, including one that makes it possible to identify your friends in a crowd.

Android Phones Versus iPhone

August 23, 2013

Android or iPhone- the question of who wins the battle of the smartphones is a long-running one that no one quite seems to know the answer to. Here is an attempt to breakdown the numbers governing this staple debate, to see which of the two really is the winner of the mobile platform war.

The first question in this regard, is of course, which smartphone has more buyers. According to a research conducted by the Kantar Worldpanel Comtech, Android is the clear winner, outspacing iOS by a margin of a whopping 52.1% in the United States alone. Talking of the worldwide market share of the two smartphones, Android dominates with a share of more than 70% versus 21% for the iPhone.

However, when it comes to tablets, the statistics favor iOS, which enjoys a market share of 53.8% versus Android’s 42.7% share in tablet shipments. Interestingly though, when we talk of the money being made by Apple versus Samsung, the former is the one raking in the bucks, accounting for 72% of the industry’s profit.

Talking of superiority in terms of apps for both the platforms, even though this is usually a completely subjective analysis, a company called uTest carried out a comparison by collecting user reviews and ratings, according to which iOS apps are more superior, with an average score of 68.5, versus a score of 63.3 for an average Android app. While iOS ranks higher for app availability (Android had to struggle for months to get Instagram), Android offers higher flexibility for its apps, allowing them to run on multiple browsers.

Another advantage that Android offers over iOS is better sharability. The sharing function called “intents” enables users to share all forms of data in between their apps simply by long-pressing the text or image. This makes tasks like sharing photos or carrying out Google searches undeniably easier. iOS on the other hand, scores high in terms of portability, with the average iPhone being lighter and more compact than its Android counterpart. Another perk to the iOS is higher consistency, which though, is balanced out by the increased customization, which Android, being an open-sourced system offers.

How To Reduce Network Congestion

July 21, 2013

Congestion in a data network has a direct impact upon speed, significantly slowing down the performance of each system in the network. A congested network has a high rate of latency, which is the term used to describe how long the data takes to traverse the network segment. This is especially undesirable in applications that are time-sensitive, where even short lags in the network speed can have a high impact on performance and end-user satisfaction. Here are some tips on how to reduce network congestion:

  • The first step is to analyze the trend followed by network congestion, with the help of network monitoring tools, which shall better help in effective troubleshooting. You need to know when the congestion is at its peak. For instance, this could be at the beginning of the day. It is also important to take note of when the congestion began- was it caused by an increase in the number of employees or other reasons? This data can help to pinpoint the most effective solution to reduce network congestion.
  • Another important consideration is in which segment of the network the major congestion occurs.. You could also consider increasing the bandwidth capacity of the affected segment.
  • If a small cluster of IP addresses is sending a large number of packets, this could be the underlying cause of network congestion. In this case, you might need to replace the malfunctioning network card, or turn off the service in the application that is responsible for generating these packets.
  • It helps to reduce the number of protocols being used in the network, and reduce the use of broadcast protocols. Using proper tuning techniques for the TCP/IP protocol can help to boost performance by up to 5 times.
  • Prioritizing the network traffic that you need can help to increase the performance of the data network. You can do this by enabling the QoS (Quality of Service) feature that is a part of typical small business networking nodes. In case of medium businesses, this can be achieved by reprogramming the network nodes like switches and routers, so that they give higher priority to the desired traffic.

Identifying the right solution for congestion in your network is a long process, that might require a significant amount of hit and trial, before you can choose the right approach to boost your network’s performance.

Using Unsecured Wi-Fi Hotspots

July 15, 2013

Public Wi-Fi hotspots are trendy and popular, for the obvious convenience that they offer. No wonder most restraints, cafes, hotels, and other public places are jumping on the bandwagon and allowing visitors to freely access their Wi-Fi networks without needing a password. Despite how tempting it is to simply go ahead and connect to these networks, you need to be prudent while doing so, as you could unknowingly put your computer at a risk of getting hacked.

The following tips guide you on how to use unsecured Wi-Fi hotspots smartly, while keeping your computer protected:

  • Remember that Wi-Fi hotspots are always unsecured connections, even if they require a password to access them. This means that hackers can easily access your private information if you are not careful.
  • Some operating systems like Mac OS X and Windows have built-in security features that can protect your computer when you are accessing the internet through such a connection. Make use of your “Firewall” by checking the “block all incoming traffic” option. Another effective security measure is to disable fire sharing.
  • One of the most targeted personal information is passwords. Installing a browser add-on like LastPass could be effective in keeping your passwords safe. Normally, a hacker can easily view your passwords by accessing your Registry or viewing your keyboard activity through something like keyloggers. LastPass stores all your passwords in a cloud which means that neither do you have to type your passwords, nor will they be stored in your computer.
  • Websites that encrypt your activity are usually safe to use, since all the information accessed on these sites remains confidential. You can identify such websites either by looking for a padlock in the address bar, or checking the URL for https:// Even if a website does not have HTTPS, you can download an add-on like HTTPS Everywhere, which will convert the connection on most popular websites into an encrypted one.
  • Before accessing any public Wi-Fi network, you want to confirm from the owner of the venue that you have the correct name of the network. This is because hackers can create their own fake network with a similar name to the original, putting your information at a high risk.
  • Finally, even after taking all the above-mentioned measures, you still need to exercise some common sense while using an unsecured Wi-Fi network. Avoid activities that expose your private details, such as banking and online shopping.

How To Get Rid Of Spam In Your Email

June 17, 2013

Are you fed up of your inbox being loaded with unwanted junk emails? Do you miss the good old days when emails were exclusive, and receiving an email actually meant that there was something worth reading in your inbox? The following simple tips tell you how you can manage your emails, ensuring that spam stays out of the way.

  • The single most effective way to get rid of spam is to avoid giving your email address to unknown sources. This might be difficult, with most websites requiring users to provide a valid email address to move forward, and some even going to the extent of offering free merchandise or discounts in exchange for your email address. An easy way to cope with this is to have an alternate email id exclusively reserved for such purposes, and a separate one for friends and family.
  • You can also make use of your email application’s filter service to send emails from a specific source directly into your spam folder.
  • Avoiding an easy-to-guess email address is another effective way to stay safe from spammers. In most cases, these spammers do not go through the trouble of finding real email addresses from the net, but simply make guesses of obvious names, like say, michael92@xyz123.com.
  • Using the options of “unsubscribing” or being “removed from this list” should be exercised with caution. While it may seem like the easy way out, it could work against you in some cases. This is because requesting to unsubscribe tells the spammer that there is a real person at the other end, and that this is a valid email address. This could make you their target when they sell their lists to other spammers.
  • If you are willing to put some extra effort into curbing these spammers, you could report them to their ISP. The first step to doing this is determining the origin of the spam. You can easily do this by displaying the entire information in the email’s header. Working from top to bottom on the “received” lines could help you identify the spam’s origin. Most ISPs will block spammers from their service upon receiving the complaint.
