There are a number of motivations for the usage of Concurrency in today's time, and in many cases now more than ever we are living in a time where concurrency has become one of the most important factor in the scaling factors of most of the applications that we develop.
In this Blog, we'll use the following shorthand:
df | Any pandas DataFrame object
s | Any pandas Series object
Also, a quick reminder — to make use of the commands listed below, you'll need to first import the relevant libraries like so:
import pandas as pd import numpy as np
Use these commands to import data from a variety of different sources and formats.
What is it?
NumPy is the library that gives Python its ability to work with data at speed. Originally, launched in 1995 as ‘Numeric,’ NumPy is the foundation on which many important Python data science libraries are built, including Pandas, SciPy, and sci-kit-learn.
It’s common when first learning NumPy to have trouble remembering all the functions and methods that you need.
In this cheat sheet, we use the following shorthand:
arr | A NumPy Array object
You’ll also need to import NumPy to get started:
What is Kafka: Kafka is a messaging system built by LinkedIn. It is written in Scala. It is designed by Linkedin when needed a messaging system for its distributed architecture.
This is the common exception which every developer deals with, each day. Today we are going to mitigate your chances to meet this exception and believe me if you use the below strategy you are going to miss this exception.
Today we’ll be discussing Null Pointer Design Patten.
What is Bit?
Benefits of using a Bit workflow
Hi, Today we’ll be going a step forward in the design of software architecture. In this article, I’ll be going through the strategy pattern.
Why do we need this? If we use this pattern in our coding style, our code will be more flexible and later if you want to alter or extend the code that varies, you can do without affecting that does not.
Very important principle #1 in design ->
take what varies and encapsulate it … and it will not affect the rest of our code
code that changes ← — — -> code that stays the same
Very important principle #2 in design ->
