This is a fun post in which I collect 10 semantic differences between Java programs and Javascript programs. Here we go

What is amazon kindle & how it stores ebooks​

Kindle is an ebook reading device with a browser and other capabilities. The kindle differs from tablets in one thing, i.e. the screen of the kindle is easy on your eyes so you can read for long hours without straining your eyes.

You can download books to kindle and they are available offline. The download happens through 2 modes.

1. Through wifi, direct download to kindle

2. Through USB transfer, the book can be downloaded from the amazon site and sideloaded.

Amazon has its ebook format (AWZ3) in which the book gets downloaded to the device and is locked with DRM.

I use windows 10 on a day to day basis. My colleagues and friends use windows too. The problem starts when the GUI disappears and we just have SSH access to the production boxes. On a production machine, running one wrong Unix/Linux command could risk your job. Here I am compiling the must know Unix/Linux commands keeping in mind the deployment and operations related tasks.

How does anyone know if their customer got any JS errors/application crashes? How does the operations team know about the crash before the customer screams on email/social media? Finding an answer to this question led to the building of my first npm package.

Here in this blog post I discuss the Top 9 & 10 of the common security vulnerabilities in a Q&A format.

Hi, no bonus points for guessing that I intend to write an e-book. I took a course to gain skills in ebook formatting. Here is the summary of the course in Q&A format.

Amazon prime reading is a book lending library for Amazon prime users. Damn, I stumbled upon this nice feature quite late.

Hey there, if you have read Russell Conwell's book Acres of diamonds, you can feel what I am undergoing when I discovered Amazon Prime reading in India. As a bibliophile, I am always on the lookout for books and things around them. I am a proud Kindle owner from 2016 and an amazon prime user for a few years but I did not notice the prime reading feature on amazon.

Amazon prime reading somehow did not fascinate me in the beginning because my kindle was not registered on an Indian address. It was tagged to Amazon USA, so most titles were not accessible even though I was an amazon prime user in India. Since I was not buying any content on Amazon USA, I decided to move my kindle to Amazon India. Looks like a hustle right. Yes, it is. According to Amazon, I moved my kindle from the USA to India. Right now my kindle is perfectly registered on amazon.in. Voila, the prime reading fun begins now.
