Being happy is a state where the mind feels pleasure and contentment at the same time. This is the state where the brain experiences stillness and yet motivated. While happiness is relative, few things are universally true.

“Happiness comes from standing on our promises”

  1. No Snooze in the morning:

First things first- before sleeping, if you tell your brain when you need to wake up, it listens without you having to use an alarm. All that matters is the intensity at which you tell your brain. If you hit the snooze button on your alarm, you are committing the biggest mistake of that day. You are not…

At the fundamental level, software programs, capture the data from various sources and present in a more readable and understandable format either for humans or for machines. If there…

Before you start reading this, do read how I passed two AWS exams in less than two months here. If you took a decision to write Cloud Practitioner certification exam, I assume you are keen to start your Cloud learning journey. It is indeed a great first step. Cloud Practitioner exam is a relatively easy exam to pass yet builds a foundation for your future cloud certifications. This is the only certification that can be done by anyone irrespective of the role that they play. It could be a developer, manager, Director, CTO, members from sales, purchasing, or financial teams.

AWS certification has been in my to-do list since 2017. Finally, Covid-19 lockdown gave an opportunity to work from home and I realized I am saving lot of driving time. I could also plan my morning time bit more effectively. In May 2020, I decided I should look at completing few certifications after we had successfully gone live with a brand new project in office.

AWS has been growing with astronomical numbers each quarter. Nothing else did seem more appropriate for me other than AWS. On May 25th I booked AWS cloud practitioner exam to take on June 6th and…

Text Classification

Text classification is a basic machine learning technique used to smartly classify text into different categories. There are plenty of use cases for text classification. Spam filtering, sentiment analysis, classify product reviews, drive the customer browsing behaviour depending what she searches or browses and targeted marketing based on what the customer does online etc. In this example, we will use supervised classification of text. It works on the principle of “training” and “validate” principle. We input labeled data to the machine learning algorithm to work on. After the algorithm is trained, we use the training dataset to understand accuracy of…

Did you ever come across this situation?
