Long Story Short
Interviewed at Amazon for SDE 1 profile . Writing production ready code on paper / board and always sharing metrics of your work with interviewer is the key at Amazon.I was rejected after calling for final round .My interview rounds were unusually longer — this is the only feedback I can collect from recruiting team.

I have 1 year and 4 months of experience as a Software Engineer , graduating from a 3rd tier college in India . …
Long story short
Strategy pattern enables an algorithm’s behavior to be selected at run time by putting them in composition instead of concrete implementation
Long story
We have two sub classes Skateboard and a Surfboard for the super class Board as a result of Generalization. We have a method ride() which implements the tricks which a rider can perform in its subclass.
Now we add one more class — Let’s suppose there comes a Flyingboard in future, which can make you fly in the sky using its jet engines and wings.
Before doing this Proof of Concept you must be aware of how to set up RaspberryPi — follow this for more .
Long Story Short
We will switch on/off LED lights remotely — this will act as a basic setup to expand the electronic circuit for any other related project
Long story
Harmandeep from Software AG and myself decided to do some PoC on trending topics in industry — RaspberyPi and its IoT implementation.
Let’s get started to control LED lights connected to RaspberryPi’s GPIOs .
We have two options :
1. Do polling from Raspi to our web server…
Long story short :
We will use Docker to do the virtualization on Windows 7
Long story :
I wanted to run a nikto test but I am currently working on Windows 7 kit — this made me to research some method to run Kali distro on Windows .
“ Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6700 potentially dangerous files/programs, checks for outdated versions of over 1250 servers, and version specific problems on over 270 servers. It also checks for server configuration items such as…

While studying Machine Learning, on edx.org, the instructor uses Gaussian Distribution to explain the Supervised and Unsupervised learning ( Please move to the discussion ahead if you are purely interested in knowing the difference ). The Gaussian Distribution approximates the Binomial distribution when the occurrence of events is very large and this is where I actually wanted to understand the difference as the formula for Binomial distribution contains multiples of a combination of occurrence of an event.
Let’s…

Notepad++ has NppFTP plugin but its keepAlive timeout problem for FTP connection made me to switch to Sublime Text 3 . We will install FTP plugin on Sublime Text .
Long Story
We will be using Sublime FTP — Its free trial can be used continuously with popups in between

We will be booting Raspberry Pi 3 with Raspbian OS using laptop for the first time.
Long story -
You need HDMI cable and a monitor to install OS on Raspberry Pi for the first time . After that you can SSH into Raspberry Pi using Putty or any other related terminal emulator connecting your laptop . But for students and other enthusiast its preferable if they can boot OS using laptop i.e a Headless install
Things I have : Raspberry Pi 3 , Ethernet cable , SD CARD 8GB and a Windows box
