Stop…. Think, Plan, then Code.

When in doubt, choose efficiency.

Don’t call hardware-related stuff, UNSAFE, you might offend the digital world and its representatives.

This computer might be a PC, an Xbox console, a Hololens 2, Iot devices on Rasberry Pi you name it. For a software company, there comes the question, how do you manage all these devices? Do you create individual operating systems for them or do you create a single base that manages them all. If a single base, how do you create the base layer? How do you…

In memory of Egeoluka, truly loved and truly missed.

For certain reasons, I have come to appreciate the title ‘programmer’.

Note: The below might seem basic but I find them invaluable in completing my understanding of the programmer’s craft.

A Programmers Task

  1. To instruct a digital computer.
  2. To model reality.

A computer computes, stores and communicates. That’s all it does and that’ s all it can ever be instructed to do.

  1. To compute— CPU or/and GPU
  2. To store — Memory
  3. To communicate — Array of I/O devices.

First Things First

sudo apt update
mkdir psq && cd psq
python3 -m venv env && source env/bin/activate
python3 -m pip install django psycopg2
django-admin startproject psq .

Checking what was installed:

python3 -m pip freeze

A million accolade for the world’s most advanced open source RDMS.

I love Microsoft’s Windows Subsystem for Linux.

Meet PostgreSQL

Windows and Mac OS: Download and Install on Windows and Mac from EDB postgres

On Ubuntu (WSL2): To install postgreSQL (client & server) on linux, we use the below code. postgresq-contrib installs additional extensions.

sudo apt update
sudo apt install postgresql postgresql-contrib

The above install…

Have you missed me C++? I have you. Spent a lot of time with python but now I have returned to renew our relationship with bits, bytes (and iterators).

I use the phrase “Golang algorithms” not because the algorithm is new and peculiar to golang but because I use the naming convention I found there and there algorithm as starting point for my solution.

Humble Appeal: If you find anything wrong with the algorithm or if you have a better implementation, I would love to here from you at the comment section. I am always open to learn new things.

Fortes fortuna adiuvat, Fortuna Eruditis Favet.

To completely understand the Python/C API, build custom types.

Working with the Python/C API gets you close to understanding language implementation.


Each identifier introduced (either through a declaration or direct definition for languages that doesn’t support explicit declarations) is associated with an object of the computing process that has certain properties. For example the class of the object (either a variable, user-defined function, built-in…

For the sake of performance and reliability, solve interpreted problems in interpreted languages and compiled problems in compiled languages.

Python gives you the power of three languages: an interpreted language Python and two compiled languages C and C++.

When I talk about Python, I mean CPython.


One of the selling points of Python is the speed (development speed) at which ideas can be bootstrapped using it. But as web apps are becoming very ambitious in providing…

updated for python 3.8.2 and django 2.2.12

et vincere nemo dividat, the experts say, Well I hear you but how do you conquer a project whose divided parts are as complex as the whole part?.

Django is large and powerful. Extensibility seems to be a guiding principle. The size of its documentation is scary but on a closer look, it is based on very simple concepts.

We will rebuild it using a top-down approach, utilizing the library till everything is rebuilt. Check the table of content below for guidiance.

First Steps — Relying on django’s HTTP and URL systems

updated for python 3.8.2

We should all aspire to be programmers like the experts of old and the experts of today.

Web development has many beautiful algorithms, I think I am in love.
