Pseudorandom numbers using Cellular Automata - Rule 30
Generating pseudorandom numbers is an interesting problem in Computer Science. In this article, we dive deep into an algorithm for generating pseudorandom numbers using Rule 30 of Cellular Automaton.
Overload Functions in Python
Python natively does not support function overloading - having multiple functions with the same name. Today we see how we can implement and add this functionality to Python by using common language constructs like decorators and dictionaries.
Isolation Forest algorithm for anomaly detection
Anomaly detection is an age-old problem and in this article, we dive deep into an unsupervised algorithm, Isolation Forest, that beautifully exploits the characteristics of anomalies. Instead of profiling normal points and labeling others as anomalies, the algorithm is actually is tuned to detect anomalies.
Everything that you need to know about Image Steganography
Steganography has been around since at least 440 BCE but with the rise of computers, the techniques have evolved to handle digital data. In this article, we see the science behind image steganography, how it exploits various properties of images to hide secrets and walkthrough a few techniques in detail.
How python implements super long integers?
Python must be doing something beautiful internally to support super long integers and today we find out what's under the hood. The article goes in-depth to explain design, storage, and operations on super long integers as implemented by Python.
I changed my Python and made it dubious | Python Internals
I changed the Python's source code and made addition incorrect and unpredictable. The addition operation will internally perform either Subtraction. Multiplication, Floor Division or Power at random.
An efficient way to stop an iterating loop
There are two ways through which we can stop an iterating loop, first by using break statement and second by making loop condition false. Let's see if one is better than the other.
