Mozilla Firefox Replacing Gecko With Servo

The time has finally come for Firefox to upgrade the aging Gecko rendering engine that served it for 20 or some years.The upgrade will enable Firefox to take full advantage of modern CPU's and GPU's, and result in lighting fast performance improvements on both desktop and mobile devices.

"Pages will load faster, and scrolling will be silky smooth. Animations and interactive apps will respond instantly, and be able to handle more intensive content while holding consistent frame rates. And the content most important to you will automatically get the highest priority, focusing processing power where you need it the most."

It wouldn't be that easy however.Switching from a solid, long serving and well proven engine to something new, constitutes a formidable task, especially when the project in question, the Firefox browser, is live and in production.

AWS Lambda For The Impatient Part 2

In the first part of the AWS Lambda for the Impatient tutorial series we set to create our very first lambda function and call it through an open, public, unrestricted and unauthenticated endpoint.This time around we add security so that calling our lambdas will require the client to authenticate through an IAM Role and User name.

Step 1 - Create a new Lambda function and API Gateway endpoint
As happened in the first part, we create a new lambda called lambda_basic_execution_helloWorldNodeJS but with the added suffix of _auth. So that we can tell it apart, call it lambda_basic_execution_helloWorldNodeJS_auth.
Despite the name change, the function's code remains the same as last time:
use strict';
exports.handler = (event, context, callback) => {
 console.log('Received event:',
                 JSON.stringify(event, null, 2));
 var inputObj = JSON.parse(event["body"]);
 callback(null, {
    "statusCode": …

Serverless JavaScript

We recently joined in an interesting two-hour long conversation about Serverless JavaScript led by Steve Faulkner of Bustle who answered questions on Bustle, the Shep framework, the mindset behind the AWS Lambda infrastructure, and related topics.

The discussion took place on the Sideway conversation-sharing platform on January 6th. Here we present the best takeaways from the session which really should be taken notice of by anyone working on AWS.

Steve Faulkner:
At Bustle we serve over 50 million unique readers per month through a "serverless" architecture based on AWS Lambda and Node.js.  Of course there are still servers but we don't manage them. This shift has allowed us to develop products faster and decreased the cost of our infrastructure. I'll answer any questions about how we made this transition and how it has worked out. I'll also discuss some of the tools and best practises including our open source framework shep

New Facebook Computer Vision Tags

Show Facebook Computer Vision Tags is a new Chrome and Firefox extension that overlays all images appearing on your Facebook timeline with a neural-network derived classification. This reveals what Facebook's algorithms makes of them. Should we be worried?
Before any image reaches your timeline, Facebook's Deep ConvNet deep learning framework scans it in order to recognize the objects that it consists of so that  it classifies it based upon those findings.
Subsequently, these classifications make their way into HTML alt tags in order to annotate the image before it appears on the web and your timeline.
As an example of how it works, consider the following picture of a dog out on the snow, shot by people inside a café.

AWS Lambda For The Impatient Part

The problem with entering the AWS world for the first time is that it's like entering a labyrinth, a futile attempt of navigating through an endless maze of documentation, policies, endpoints, services, tokens and authentications. The task of having to hook all that up in order to get on with your job is daunting. Here is the help you need for AWS Lambda.

Tthe range of AWS offerings is just immense with so many services and providers to choose from, like EC2, S3, Athena, Kinesis, Lambdas, CloudFront, DynamoDB, API Gateway, and the list goes on.

In this tutorial, however, we're going to take a deep look into the Lambdas and the serverless architecture they support.The beauty of serverless computing isn't that you don't need a server, but you don't need to manage one.Your function lives in its own space on the cloud, capable of being called through multiple entry points, while despite self-contained, still capable of calling other functions or APIs , tr…
