Dimensionality and High Dimensional data in Machine Learning Dimensionality In Machine Learning and Data Science world dimensionality refers to the number of attributes a dataset has. For example, we have a telecommunication dataset having large numbers of attributes (region, tenure, age, address, etc). Each attribute is written in a CSV file, with each column representing each dimension. Dimensionality in machine learning is different from those which are used in mathematics or science. High Dimensional Data High Dimensional data means, the dataset in which the number of features exceeded the number of observations. The dataset has extremely high attributes and makes it more complex for computations. For example, we have ‘n’ numbers of observations or data points and ‘p’ no. of features or attributes. If in a dataset the values of n and p are 1000 and 2000 then the data becomes high dimensional data. In simple words no matter how big or small is the dataset if the number of observatio...

How to Launch Container within Container? In this article we will see how we can use the Concepts of Docker to achieve Containerization within Container. To launch another container within a running container is quite a tedious task but in this article I will show you how easily you can achieve this by applying right concepts. In this article I will be using few concepts of docker like Dockerfile , mounting volume , mounting port and few basic docker commands . Before starting with the container we need to make sure that Docker is installed and configured in our system. If docker is not configured then you can use my automated script which I made for installing and configuring docker from my GitHub Repository . After setting up with docker now we need launch a container so that we can launch another container inside it to achieve Containerization within container. There are two ways to launch container. By using docker pull command By using Dockerfile In this ...

How to Grab Anyone's IP Address? IP Address is abbreviated as Internet Protocol Address which is a unique address for all the users present on the internet. Whenever we visit any domain or click any link /images on the internet, our public IP address is being shared that source. But what if, we want someone’s IP address intentionally or we want to track someone. So in this blog I will show you how you can easily grab anyone’s IP Address just within a few steps. To grab IP address I will be using an online Web Application named Grabify IP Logger . It is an online tool that is used for IP Lookup . Before beginning with the tool it is recommended to use browser proxy or VPN . Here we have used browser proxy as you can see in the top-right corner in the image for accessing Grabify. Now we need to register ourselves in this application to use it. After registration, we have to log in to the application. After registration and login into the application, we are ready to use it. To grab...

Package Management in Linux distros In the Linux world, there are basically two different types of community-based distribution. One is  Debian based and another is based on the fedora project. Several distributions of Linux use mainly these two community distributions. Unlike some of the most popular distros like Kali, Parrot, Ubuntu, etc which uses Debian based, Redhat Enterprise Linux is based on the fedora project. Package Management Debian based distros Some of the most popular Debian based distros are Kali, Parrot, Ubuntu, Linux Mint, Deepin, BackTrack, Astra Linux, etc. In Debian based distributions the package management is done by apt  and it is configured by default when you install the operating system. To install any package in Debian based use command:  apt-get install package_name  for example, apt-get install leafpad. To remove any package:  apt-get remove package_name; to search for any package installed:  apt-cache search package_...

Cryptography: The Art of Hiding Cryptography can be defined as a method of protecting the digitally shared information between the users. In simple words, it helps us to protect our 'confidentiality' or 'privacy'. The word cryptography consists of two words, 'crypt' which stands for 'hidden' and 'graphy' which stands for 'writing'. Cryptography is basically related to the study of 'cryptology' and 'cryptoanalysis'. It includes various techniques such as microdot, combining words with images, merging images in audios and other different methods to maintain your confidentiality. If we talk cryptography in terms of information security  it is more often associated with scrambling or converting the plaintext into an encrypted text (or ciphertext ) and again decrypting (or decipher ) the encrypted text into the plain text. When we talk about cryptography we will always come across the two words, i.e, Encryption...
