WhatsApp Video Calling Feature Link is a Spam

The voice calling is done and WhatsApp has been thinking about introducing video calling feature for its users. But the official statement or the update is not yet released and it strike an idea in hackers’ minds to cash in the enthusiasm of WhatsApp users.

 

Recently, WhatsApp users have been receiving a message with a link from their friends’ circles saying that it will update the application and enable video calling feature. The link is not actually an official updater but a hackers’ bait for WhatsApp users. It is found to be uploading your sensitive information and contacts list on your phone to hackers’ databases.

 

Beware of WhatsApp spam

 

How it works?

Just like many other average spams, this video calling feature spam also impersonates the original updater like UI when clicked on the link. It will show a progress bar mocking the update in front and will be uploading your information in the background. After it is completed, it will then be propagated to your friends’ circles and the same happens to them too.

 

How can we say that it is spam?

If you are using WhatsApp since last two updates, the voice calling feature and material design, it would be easy to recognize this as a spam right then. All the previous updates were applied by getting a call from voice call enabled WhatsApp friend or from Google Play application update service. Isn’t it? If so, why would you get a separate unknown link to update it this time? Do you think updating the application through third-party link is safe?

 

If you have clicked on the link and have seen that progress bar UI till completion, check now if you got any such feature enabled on your WhatsApp. Definitely, you won’t.

 

How to keep yourself safe from this scam?

It’s simple. Don’t click on the link you receive from your friends through messages. WhatsApp can propagate coded messages that can easily track your details in seconds. If you are aware of messages like ‘share this message and see the red apple moving’, you could imagine the range of vulnerability.

 

Be safe!

Lenovo A7000 vs. Micromax Yu Yureka vs. Xiaomi Mi4i

Lenovo has released a new phablet, A7000, into the Indian market so recently. People who were going bananas over Micromax Yu Yureka so far have got a reason to stop their excitements. Just like Micromax, Lenovo has also made it available via flash sales on Flipkart.

 

Interestingly, Micromax has also decided to stop these flash sales on Amazon and is selling it in an open sale from May 6th, the same date on which the second flash sale of Lenovo A7000 happened. Seems like Micromax Yu Yureka started feeling the heat.

 

Also, the new Xiaomi’s beauty Mi4i looks fantastic in design and very good in performance. It gives a good competition to the budget range smartphones like Yureka and A7000. If it is taken benchmark wise, Mi4i wins the race followed by Lenovo A7000 and Micromax Yu Yureka.

 

Both these three phones have pros, cons and issues and it is hard to pick up one among these without a detailed comparison.

Possible Solutions to DNS Errors After Changing URL in Webmaster Tools

Bloggers and webmasters often encounter DNS errors in Google Webmaster Tools. The message saying Over the last 24 hours, Google bot encountered 40 errors while attempting to retrieve DNS information for your site. The overall error rate for DNS queries for your site is 14.8%.” will worry you till it is resolved.

(The values seen in bold are variable from site to site)

We will discuss the possible solutions to this problem and will try to find a solution(for which you came here) that can solve your problem by the end.

dns-erros-possible-solutions

Solution #1:

Check for error rating – If the error rating is closer or equal to 100%, check if name servers are correctly configured or not. Go to your domain registrar’s dashboard that is provided to you when buying the domain and set the values correctly. If you have no technical knowledge to change them for yourself, ask the registrar without any hesitation.

If you find no clue of how to contact your domain registrant, please check the email format designed by our friend +Rohan Chaubey:

To The [company name] Customer Support Team,

I recently bought a domain from your site. I am facing some DNS errors after changing the URL in the Webmasters tools. While checking for error rating I wanted to verify if name servers are correctly configured or not.

I possess no technical knowledge to change them myself. I would highly appreciate if your staff could help me in getting them configured correctly.

I am ready to bear any charges for your time and service if needed. Thank you so much for your time and consideration. I look forward to hear back from you soon.

Thanks,
[Your name].
[Account details or web address].

Solution #2

Upgrade your hosting plan – If the error rate is less than 100%, the problem might be caused due to server overload. This happens mainly due the following 7 reasons:
  1. Uncontrollable amount of natural web traffic trying to access the site within the same time.
  2. Distributed Denial of Service(DDoS) attacks on the server where you website is hosted.
  3. Uncontrollable amount of unusual or bot traffic sent to your website.
  4. Affected web browsers and computers due to viruses and worms.
  5. Because you have hosted your website on a limited capability host and you get excess number of client requests to access that page that your server cannot handle.
  6. Low speed internet connections finding it difficult sending request to servers and receive the response.
  7. Maintenance or repairing of web servers
The possible solution to this problem is upgrading the resources to your server and improving the configuration that can handle ample of client requests at once. Also, consider security features in order to avoid hacker attacks on your website.

Solution #3

Fixing DNS problems on your own computer – Sometimes, the DNS configuration on your own computer might get disturbed due to the recent changes you have made to your network or the changes made by your ISP.

To detect if the error is with your computer, ask your friends to check if they could open your website without any glitches on their side. If they could open your site normally from their side, it would definitely your computer configuration problem.

I have faced this situation in the past once and worried why my website alone is not working on my side. Later, with the help of my online friends, I could figure out the real problem is and changed and back the DNS configuration from Google to default.

IPV4-configuration

Solution #4

Fetch as Google – This is the simplest solution ever for this problem. Use ‘Fetch as Google’ option in Google Webmaster Tools to tell Google bot to re-crawl your website once. It will Google to update the status of your website.

Perform this step even after solving the problem once. It will be helpful in reducing the ‘URL not found’ errors due to this DNS blackout.

Hope these solutions would help you get your problem solved. Please share if you have any other or better solutions than specified ones. We’ll update them in the article with an attribution of your name.

Also I would like to thank Rohan Chaubey, the wise soul in young body for helping us out with the letter format to contact the hosting providers. He’ll be with us from today, if you need any other help regarding the composing of any emails

Mobile vs. Desktop: What Features Make Mobile More Personalized Than Desktop

A desktop computer would supposedly be a powerful machine, sitting in front of which you can carry out many daily business tasks. A mobile phone on the other hand is also a daily tech companion which is embedded in our lives and real-time needs. When it comes to personalization, everything counts. It is the ability to blend the gadgets the way we like to live our routine. Ability to customize a digital gadget is a good thing. Or else you’d have to blend your life in reverse to use them.

 

Wait! Before we start, let’s talk a bit about the ‘actual’ personalization.

 

Personalization is customizing something according to your likes, needs and comfort. In case of electronic gadgets like mobile phones, personalization is building an attachment with them in your daily routine. We actually use and depend on them for performing daily tasks. Their loss can be easily identified and felt difference.

 

Can’t we personalize desktop computers?

 

Of course, we can. But the levels of customizing is limited to a place or mood. You don’t want to switch-on your computer in times of sickness or no work, but you will still hangout with your mobile phone. What do you think is the reason behind it? Specifically, it might be the ability to handle and use them with ease even from your sick bed.

 

Hold the thought and let’s get started!

 

Mobility

Mobile phone, the name itself says that it can be carried with us anywhere. Mobility of goods is a great personalization feature. Things we need with us all times must be allowed to carry.  Something like carrying a wallet, carry a wrist watch, carrying a mobile phone also comes under this.

 

Personalizing to match with the style

If we talk about mobility, style comes to the concern. A desktop computer can never be installed with stylish back covers in colors but we can do it with a mobile phone. You can change the mobile phone covers and shells to match up your attire according to situations. Surprisingly, style is one of the factors why people actually struggle to buy a mobile phone that matches their style. That is why companies revamp their product designs for every new model released in the market.

 

Shopping has gone mobile

People buy anything online now. In fact, people buy anything from their mobile phones now. The sophistication of shopping from home has been optimized to shopping through mobile from anywhere. You may not have to get up from bed and sit in front of a desktop computer to go online shopping.

 

mobilephone-vs-desktop

 

Haven’t you noticed the ecommerce sites going completely mobile very soon? What you think might be the reason? It is the possibility to personalize a mobile phone better than a desktop.

 

Personalizing communications

It is not merely possible to customize your communication preferences on a desktop whereas you have full control of receiving calls and messages on a mobile phone. You can keep the conversations private on a mobile phone but cannot get that privacy on a desktop computer at home or office. After all, many desktop computers at home are used by more than one person. So, it would not be easy to protect your conversations from being watched on a large screen. Though you use different accounts on a computer, the admin or parent will still have access to the rest of them anytime.

 

Personal digital assistant

A mobile phone is no more a device to make calls. It is 2015 and the mobile phones we are seeing today are well evolved in terms of technology. A mobile phone which is also called a smart phone today is embedded in our personal life that a desktop cannot do. One can just speak to their phone to perform tasks on the phone. We can personalize it in sync with our timings. It reminds us about our meetings, daily schedule, birthdays and performs other important automated tasks.

 

Walks with you

Yeah, a mobile can walk miles with you. The adaption of GPS hardware technology and Google smart maps software technology have brought drastic changes the way a mobile phone is used. It will assist you, help you and walks with you as long as you go proving the old saying “If you can talk, you can walk through the world” wrong. Now, even the dumb and deaf can do it, breaking all the inability limitations.

 

Secures your moments

Mobile phone is not actually called a ‘mobile phone’ these days. It is called the’ smartphone’ because of the possible things it can do. After mobile phones started having digital cameras, the need to get one separately has dissolved in time. You can shot the moment right away when you feel like taking one. Also, there available the pre-installed photo editors which make the frozen moments twinkle.

 

All-in-one gadget and that is called a mobile smartphone

Mobile is not just a mobile phone anymore. It has been evolving to serve multiple purposes of a human being. The mobile phone, so called smartphone which we are using today has gone through many mutations and many more yet to come. Though it is funny, it is true that a smartphone today is used to make calls less often and do more daily tasks mostly.

 

Moreover, the technical specifications of smartphones today are over smarting the desktop computers. The sales graph of mobile phones in the past 5 years shows how personally they were embedded in people’s lives. Now tell me, how many times do you look at your mobile screen in a day just to make calls?
