Creating a systemd service

Format of systemd service files

service files for systemd are writtern in a format similar to toml and ini

Sections in the service file

[Unit] and [Install] - carries generic information about the unit that is not dependent on the type of unit
[Service] - carries information about the process the service files executes

Why is numpy's matrix multiplication faster than matrix multiplication implemented in plain python?

numpy's matrix multiplication are written in c/c++ which means they can be pre-compiled to give better performance

Why can't we compile python code?

compiling python code is posible if someone writes a compiler for it, through this is very hard and no one has done it yet, but there are compilers which compile some parts of the python code
