Google also launched new game controllers. The controller can connect directly to Google data centers and control the game without any unnecessary hops added by laptop/computer. Hopefully, by allowing the controller to connect directly data centers, there won’t be any annoying lag. Stadia will work with all current controllers and keyboards.

Here is a video shared by TechInsider:

In a server world, to run code we first provision a server. A server can cost from anything between USD 3.50 (on AWS LightSail) to several 100 dollars for a large EC2 instance. After that code is deployed on the server. The user pays for the entire month, it doesn’t matter if the server is processing any requests or not.

How does Serverless work (AWS Lambda)?

AWS Lambda is the de facto leader and torch bearer in the serverless world. In the serverless world the code is executed only when it receives a request. AWS has a large number of shared servers which execute customer’s lambda requests.

So when a request to a lambda function is received then AWS first deploys this code on their cluster and then it executes the code. After the execution, the response is returned.

The above might look a bit hectic and may appear as if serverless functions are slow. But AWS has spent a lot of time in optimizing AWS Lambda. A simple function has latency less than 10 ms.

Deploying code to AWS Lambda.

You can use the UI to deploy code and test a lambda function. However, the recommended way is to use the AWS Serverless Application Model or AWS SAM. SAM is a lot like AWS cloudformation templates but built keeping serverless in mind. Here is a simple SAM template for a hello world function. You can learn more about it here.

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: A starter AWS Lambda function.
Parameters: 
    IdentityNameParameter: 
      Type: String
Resources:
  helloworldpython3:
    Type: 'AWS::Serverless::Function'
    Properties:
      Handler: lambda_function.lambda_handler
      Runtime: python3.6
      CodeUri: .
      Description: A starter AWS Lambda function.
      MemorySize: 128
      Timeout: 3
      Policies:
        - SESSendBouncePolicy:
            IdentityName: !Ref IdentityNameParameter

AWS let’s you create a sample SAM application with a few clicks. You can also chose from one of their many SAM templates. You can browse sample SAM templates on their git respository as well.

This is the sample python code for “Hello World”:

import json

print('Loading function')

def lambda_handler(event, context):
    #print("Received event: " + json.dumps(event, indent=2))
    print("value1 = " + event['key1'])
    print("value2 = " + event['key2'])
    print("value3 = " + event['key3'])
    return event['key1']  # Echo back the first key value
    #raise Exception('Something went wrong')

What about APIs? Or remote invocation?

AWS Lambda is inside AWS’s account and can not be invoked from outside world. To invoke lambda from an endpoint, it needs to integrated with API Gateway. API Gateway is used to filter, structure and pass all requests it received to AWS Lambda. API Gateway supports swagger models as well which is part of Open API initiative.

After AWS lambda’s success, various companies have launched their own serverless systems. Users have a wide variety of services to chose from. Users can run their serverless code on Microsoft functions, IBM’s serverless, Google functions or even run serverless node.js functions on Ethereum’s blockchain.

GullyBoy is loosely based on the life of Divine and Naezy, we say loosely because a lot of things shown in the movie never happened. Let’s have a look at what are the facts and what is fiction.

Elon Musk’s Starlink is working on building a network of 12000 satellites to provide free, high-speed global internet access by the 2020s. The project is expected to cost around $10 billion. SpaceX’s planned satellite fleet would be nearly three times larger than the number of satellites already orbiting Earth.

Just sometime back I saw Hollywood movie which showed that just the moment a guy clicked on software he just downloaded over the internet, his computer exploded and went like a bomb. This landed me to an amazing question “Can a computer ever explode? “
