Serverless: Inheritence of Cloud Computing

Serverless computing is a cloud computing execution model in which the cloud provider dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity. It is a form of utility computing.

Serverless computing still requires servers. The name "serverless computing" is used because the server management and capacity planning decisions are completely hidden from the developer or operator. Serverless code can be used in conjunction with code deployed in traditional styles, such as microservices. (Microservices is a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services.) Alternatively, applications can be written to be purely serverless and use no provisioned services at all.

AWS Lambda, introduced by Amazon in 2014, was the first public cloud vendor with an abstract serverless computing offering. AWS Lambda initially supported only Node.js. It now supports Python, Java, and C#, and code written in other languages can be invoked indirectly via Node.js.

Serverless computing is more cost-effective than renting or purchasing a fixed quantity of servers, which generally involves significant periods of underutilization or idle time. It can even be more cost-efficient than provisioning an autoscaling group, due to more efficient bin-packing of the underlying machine resources.




Some Odd Knowledge:

•      In 2016, "WHATEVER" was voted the most annoying word in English in a Poll by the Marist Institute of Public Opinion for the eighth year running. 
•      38% Americans reported that whatever annoys them more than any other word used in conversation.

Do you know! - How many Nations have Bullet Trains?

Without further ado, let me tell you the Answer. There are 16 Nations which has Bullet Trains.

Countries included in this list are China, Japan, Spain, France, Germany, Italy, Turkey, South Korea and Other European Nations. Among all, China has the Largest network.

A railway is considered as High-Speed Railway when the speed exceeds 250 kmph. Maglev Trains are the newest technology of high speed trains. They are based on Magnetic levitation to run and unlike conventional trains that use wheels. Maglev have superior controls as its acceleration and braking doesn’t depend on friction of the track. It is very costly and only three Nations hold it China, Japan and South Korea.

Some Facts:

        1.    World’s first High speed rail system Shinkensen (or Bullet train) started ops at speed of 210 kmph in 1964.
        2.    West Germany’s TR04 Maglev touched 250 kmph in 1973.
        3.    Accelerated by steam rockets, West Germany’s Komet Maglev touched 401 kmph in 1975.
        4.    Japan’s ML-500R Maglev succeeded in crossing more than 500 kmph for the first time in the world when it touched speed of 504 kmph in 1979.
        5.    Japanese LO Maglev hit a record 603 kmph in 2015.

Worry yourself for happiness

'Don't Worry be happy' was a hit in 1989, but what does it mean? Is there a 'worry' button you can turn off? Worrying is not as bad a response to a situation as people patting your back and asking you to cheer up make it seem.

In small doses worrying can help you recover from trauma and depression, and increase healthy behaviors, says an article in New York Magazine. "worries tends to be more successful problem-solvers, higher performers at work and in graduate school, and more proactive and informed when it comes to handling stressful events."

We all know why worrying is considered bad. It is unpleasant and distracting, makes us irritable and deprives us of sleep. "It sucks up so much of your mental energy that it can be impossible to actually focus on what's happening in front of you."

But when participants in a 1996 study were asked if they could list some upsides of worrying, they said it made them better planners, more analytical thinkers, and conscientious. Worriers were more likely to have safe sex, wear sunscreen, and buckle their seat belts, the article says.

How did worrying produce positive outcomes? Active worriers don't just take steps to prevent something bad from happening but also try to reduce their own need to worry. If you are stressed over a job interview, you will not only spend more time preparing for it but also look out for other jobs. "It's like the opposite of a vicious cycle - the more you worry, the more you plan, the less worried you actually need to be."

Even if things don't work out, people who have been worrying about failure are prepared for it. "For a constant worrier, bad news is rarely a total shock"

Add a "Voice Search" to your Search Engine

    Create a Gonik search engine just like a google search engine...

      The HTML5 Web Speech API has been around for few years now but it takes slightly more work now to include it in your website.
Here's a html code...

<style>
  .speech {border-style: solid; width: 400px; padding: 0; margin: 0;
height:30px; }
  .speech input {  height: 30px;}
  .speech img {float: right; width: 35px }
body {
    padding:150px 500px;
    font-size: 10em;
    font-style: italic;  
}
</style>



<!-- Search Form -->
<form id="labnol" method="get" action="https://www.google.com/search">
<body><font color="orange">Gonik</body>
  <div class="speech">
    <input type="text" size="46"   name="q" id="transcript" placeholder=" 

Search Goonik or type URL" />
    <img onclick="startDictation()" src="//i.imgur.com/cHidSVu.gif"

title="Search by voice" />
  </div>
</form>

<!-- HTML5 Speech Recognition API -->
<script>
  function startDictation() {

    if (!('webkitSpeechRecognition' in window)) {
        alert("Microphone is Disabled");
    }
    else{

      var recognition = new webkitSpeechRecognition();

      recognition.continuous = false;
      recognition.interimResults = false;

      recognition.lang = "en-US";
      recognition.start();

      recognition.onresult = function(e) {
        document.getElementById('transcript').value
                                 = e.results[0][0].transcript;
    //console.log('You said: ', event.results[0][0].transcript);
        recognition.stop();

The Future of Memory - DNA Hard Disk

            The storage of information is always a challenge to the computer engineers. Ever increasing data is expected to reach 170 zetta bytes till 2025. The solutiion lies in DNA, which is incredibly dense. The whole genome of an organism fits into a cell that is invisible to the naked eye. That's why computer scientist are turning to microbiology to design the next best way to store ever increasing collection of digital data.

Comparison.  (Source: Nature.com)

           The point of using synthetic DNA as a sort of double-helix hard drive is simple--you can store astounding amount of data in the tiniest amount of space, and it will be stable forever. Scientist says a single gram of DNA could hold 4.5 billion gigabytes of data and remain stable for millenium. DNA storage could form highest-density large-scale data storage scheme ever invented.

Advantages:

           DNA has advantages that other storage media do not. It takes up less space. It is durable, as long as it is kept cold, dry, and dark -- DNA from mammoths that died thousands of years ago can still be extracted and sequenced. And it has a 3.7-billion-year track record. Floppy disks, VHS, zip disks, laser disks, cassette tapes...every media format eventually becomes obsolete But DNA will never become obsolete.

Obstacles:

           The use of DNA in data storage is still in its early stages...and...the immediate use of the DNA data storage is for archiving. However, it's still quite expensive to archive...data on DNA. In fact, synthesizing the DNA costs $7,000 alone, while reading it costs $2,000.     

Now All Facebook's Translation is powered by Artificial Intelligence

Spend enough time on Facebook, and you’ll likely encounter a post written in a tongue that’s foreign to you. That’s because the social network has two billion users and supports over 45 languages. On Thursday, Facebook announced that all of its user translation services—those little magic tricks that happen when you click “see translation” beneath a post or comment—are now powered by neural networks, which are a form of artificial intelligence.

Back in May, the company’s artificial intelligence division, called Facebook AI Research, announced that they had developed a kind of neural network called a CNN (that stands for convolutional neural network, not the news organization where Wolf Blitzer works) that was a fast, accurate translator. Part of the virtue of that CNN is that instead of looking at words one at a time, it can consider groups of them.

Now, Facebook says that they have incorporated that CNN tech into their translation system, as well as another type of neural network, called an RNN (the R is for recurrent). Those RNNs, Facebook said in a blog item about the news, are better at understanding the context of the whole sentence than the previous system, and can reorder sentences as needed so that they make sense.

As an example of the difference between the two translation systems, Facebook demonstrated how the old approach would have translated a sentence from Turkish into English, and then showed how the new AI-powered system would do it. The first Turkish-to-English sentence reads this way: “Their, Izmir’s why you said no we don’t expect them to understand.” Now check out the newer translation: “We don’t expect them to understand why Izmir said no.” Notice how the AI fixed the mistakes in word and phrase order?

While neural networks had been working together with the more traditional translation system before today, now all the translation gets its smarts from AI.

The new system is more accurate than the old method...
