This is the most unchallenging data analysis I’ve ever done, on the simplest data set: Airlines but you’ll love it!

It had been a long break working on any data science project. The last project I did wasn’t successful and burned up my 90+ hours working on new frames on my core i3 computer. I know it’s a headache. I couldn’t start my new year with all the woe. Beginning 2021 up with something interesting and enlightening and simple(most important) was something I was craving.

I opened up my pc wide and started searching for a data set on Kaggle…

• Memory allocation of a 1D array dynamically

Quick Notes:

the malloc() Allocates memory and returns a pointer to the first byte of allocated space

calloc() Allocates space for an array of elements, initializes them to zero, and returns a pointer to the memory

free() Frees previously allocated memory

realloc() Alters the size of previously allocated memory

Memory allocations process

In computer science, the free memory region is called the heap.

The size of the heap is not constant as it keeps changing when the program is executed. In the course of…

Your ferry made decent progress toward the island, but the storm came in faster than anyone expected. The ferry needs to take evasive actions!

Unfortunately, the ship’s navigation computer seems to be malfunctioning; rather than giving a route directly to safety, it produced extremely circuitous instructions. When the captain uses the PA system to ask if anyone can help, you quickly volunteer.

The navigation instructions (your puzzle input) consists of a sequence of single-character actions paired with integer input values. After staring at them for a few minutes, you work out what they probably mean:

• Action N means to move…

Clean up your cache in a few easy steps!

GNU/Linux has implemented efficient storage management for its users. But have you noticed your Linux system running out of space, filled with unused packages you installed months or years ago? How do find them and remove them? Here are a few valuable tips!

Cache File Location

Cache files are stored in /home/username/.cache which mostly consists of your browser’s data, IDE’s (if you use any ) and other software. Each user has its own data and this can build up exponentially . …

Hello Everyone ! So this article is about using graph objects directly to create geo-maps .Plotly’s Python graphing library makes interactive, publication-quality graphs.

• Overview
• Installation on Jupyter notebook
• How to create maps for countries apart from USA?
• Using graph objects directly.
• Create maps using geoJSON!

Overview

You can write programs that launch other programs on a schedule by using the subprocess and threading modules.

For example, you could schedule a backup for every week or month and at a scheduled time like 10: 00 pm.

Alright, before we get started I’d like to give a glimpse of what this article covers.

The Time Module

Your computer’s system clock is set to a specific date, time, and time zone. The built-in time module allows your Python programs to read the system clock for the current time…
