Puscas Arena, Budapest during Matchday (NED VS CZ)

As a fanatic football fan, it is a dream to watch European Championship knockout match in the stadium. The championship was cancelled in the year 2020 due to pandemic.

Today we’re discussing about getting rid of WatsApp and adopt Signal. Let us discuss in a brief why Signal is better than WatsApp and why should we adopt this?

Before going into detail, let us see some of the recent facts. On February 21, 2018, Moxie Marlinspike and WhatsApp co-founder Brian Acton founded Signal Foundation, nonprofit organisation. In January 2021, WhatsApp announced update to Privacy Policy which states that WhatsApp will share user data with Facebook. Users will be forced to accept by February 8, 2021, or stop using the app. Previously, users could opt-out of such data sharing, but…

Basic architecture for Informatica Product 360

The above diagram is self explanatory. I put some cloud components for data export operation. This is a plain and simple way to manage your product data from various source system residing in various other systems.

Now, Cloud Function, Cloud CDN and Apigee API platform is just examples of doing the operations. Similar functionality is available if you’re going to use IICP (Informatica Intelligent Cloud Platform). Also, Data lake can be replaced by more sofisiticated Snowflake. Extra 3RD Party API Management is widely distributed between different software and services.

This article describes the way two or more people collaborate in a project shared in Github. For this, I choose a live project in Github with path https://github.com/biswarup81/prescription.git

Step-1 : Identify the branch. The figure below shows the number of branch. Let us assume that the branch which we’ve identified is prescription-manas-billing.

Once you’ve identified the proper branch name, then you’ll be downloading the complete code-base into your local system. See step-2 for details.

Step-2: Download and run Git from https://git-scm.com/downloads into your local machine (Laptop/Desktop)

Typical Data Engineering Architecture using Google stack

Before I start writing about my experience, I would like to say that I did not study regularly, but I study with a deadline and somehow I managed to complete the deadline.
