The Emerging Architectures for Modern Data Infrastructure

This is a very well written summary of the current data science landscape. Everybody building data related solutions should have a good read of this.

Five years ago, if you were building a system, it was a result of the code you wrote. Now, it’s built around the data that is fed into that system. And a new class of tools and technologies have emerged to process data for both analytics and operational AI/ ML.

AWS Perspective | Implementations | AWS Solutions

AWS just released AWS Perspective, a new tool to help you create diagrams about your AWS workload/architecture.

In a way this is long overdue. There are quite a number of companies in this space already. AWS’ version supposedly is better integrated and allows you to link to the resource directly in AWS console.

It seems to be quite useful, though it doesn’t come cheap. Someone posted on Twitter that the cost estimate comes up to USD500+ (every month) to use it.

YouTube Down According to Reports Worldwide & Twitter Reacts

Woops. YouTube is down at the moment.

It’s interesting that Google chooses to display an encrypted message (presumably containing details of the error) on the client browser. This is certainly a novel way for users to report the problem without exposing potentially sensitive details (eg. file paths) to them.

YouTube is down and reports are coming in worldwide about the service being unavailable.

Update: Service is up after about 2 hours
