Part 2 of the JWT authentication with ASP.NET Core 7 guide — Intro This article is the follow-up to my previous guide How To Add JWT Authentication To An ASP.NET Core API, that you can find here: How To Add JWT Authentication To An ASP.NET Core API Step by step guide to user registration and authentication using ASP.NET Core 7, Identity and PostgreSQLmedium.com The overall goal with these two articles is to show you how to implement authentication in both the backend API and the frontend UI.

Step by step guide to user authentication using ASP.NET Core 7, Identity, PostgreSQL — The goal After completing this guide you will have created an ASP.NET 7 web API that exposes a secure endpoint. The secure endpoint can only be accessed by users who have a registered account in your system. To store the user data you will be spinning up a PostgreSQL docker container, and…

A bit of research for the curious React developer — For some time now I have been wondering if there is a benefit to using function over const when declaring functional components, and vice versa. So, I decided to do a little research, and I will sum it up for you in this article. TLDR It does not really matter whether…

How to interpret the coef_ attribute of the linear SVC from scikit-learn for a multiclass classification problem — In my recent post I showed you how to interpret the coef_ and intercept_ attributes of a fitted SVC model for a binary classification problem, as well as how to plot the deciding plane. If you have not read it yet, I recommend that you check it out before reading…

How to interpret the coef_ attribute of the linear SVC from scikit-learn for a binary classification problem — This post will teach you how to interpret the coef_ and intercept_ attributes of scikit-learn’s SVC, and how they can be used to make predictions for new data points. I recently finished a project where I had to deploy an SVC in C. I trained an SVC in Python in…

Let’s uncover why the size of an integer in Python is at least 24 bytes — If you are a seasoned programmer then feel free to jump straight to the part called “The types of numbers in Python”, as the first part will probably not teach you a lot of new things. Otherwise, just keep reading. Explicit and implicit types Python is a super popular language, and one of the…

How to find the derivative of the Sigmoid function for neural networks — Easy step by step walkthrough — I recently read a great post here on Medium that showed me how I could implement my own neural network from scratch. This was valuable for my understanding of machine learning and especially the inner workings of neural networks. The network that I learned to implement used the Sigmoid function…

A beginner’s guide to plotting with pandas — When doing data science or machine learning work you often use pandas to load and structure your data and matplotlib or seaborn for data visualizations. …

Learn to use an ARMA model to make better predictions than an AR model — In one of my previous guides we took a look at how an autoregressive model can be used to make forecasts for the future using time series data. In this post we will attempt to improve the accuracy of our predictions by using an alternative approach. Make sure to check…
