Python
Python Functions
Functions group reusable logic behind a name, and Python gives them unusually flexible argument handling.
CSS
CSS Flexbox Layout
Flexbox lays out items along a single axis and distributes space between them, which makes responsive rows and columns simple.
DBMS
Normalisation in DBMS
Normalisation organises tables to remove redundancy and update anomalies, one normal form at a time.
Java
Introduction to Java
Java is a statically typed, object oriented language that compiles to bytecode and runs on a virtual machine, which is what makes it portable.
Java
Setting Up Java and Writing Your First Program
Install a JDK, understand every word in the classic first program, and learn what compilation and execution actually do.
