The Analytical Engine

This was the first fully-automatic calculating machine. British computing pioneer Charles Babbage (1791-1871) first conceived the idea of an advanced calculating machine to calculate and print mathematical tables in 1812. This machine, conceived by Babbage in 1834, was designed to evaluate any mathematical formula and to have even higher powers of analysis than his original Difference engine of the 1820s. Only part of the machine was completed before his death in 1871. This is a portion of the mill with a printing mechanism. Babbage was also a reformer, mathematician, philosopher, inventor and political economist.

It was designed by Charles Babbage, a polymath in 19th century. He designed the machine but was never able to build a complete working model in his lifetime due to constraints of fundings. It would take nearly over a century before someone attempted to design a General-purpose computer Importance of Analytical Engine does not end… Continue reading The Analytical Engine

Shells in Linux

On the suggestion of some of my Linux afficionado friends, I decided to look into changing my default shell in Mint from Bash to another shell. After some surfing on the web Fish and ZSH seemed to be the viable options. ZSH attempts to maintain compatibility with Bash while Fish ignores it. On trying both… Continue reading Shells in Linux

zip in Python

While trying to learn more about list comprehension in Python, I came across a very useful function called zip. Zip combines two or more iterables into an iterable consisting of tuples. Tuple on index n has elements having index n from all the iterables passed to the zip function. Example: Output: 3 6 9

Functional Programming with Scheme

Paul Graham’s essays on Lisp and frequent discussions on HackerNews piqued my interest in Functional Programming. Hence I decided to take a deep dive to explore this topic. Functional programming as a very fascinating history, with Lisp being the second programming language created after Fortran. Lisp was quite popular in universities but it suffered an… Continue reading Functional Programming with Scheme

Exploring the world of DevOps, CI-CD, andContainers on steroids (WIP)

Note: Work in progress! This blog is about exploring so-called DevOps/Infra: containers (docker/podman), containers on steroids (k8s), and the world of CI and CD. Abstraction Layers in Computer Host Computer (bare-metal) > Virtual Machine (VMware / VirtualBox / Vagrant) > Containers (LXC/LXD) What is Containers and some of their features? Light weight / Encapsulated Abstraction… Continue reading Exploring the world of DevOps, CI-CD, andContainers on steroids (WIP)

Complex cases may require a combination of several libraries however for simple webpages only two libraries are sufficient. The libraries required are requests(the most downloaded Python library) and… Continue reading Web scraping with Python

My Journey with Linux

I don’t know which year will be ‘the year of Linux’ but Linux for sure plays an important role in tech. My first experience with Linux was when I started working with a Raspberry Pi. The OS for the Pi was Raspbian,a Debain derivative. Since Raspbian I have worked with a variety of other Debain… Continue reading My Journey with Linux
