How To Find Duplicate Values in MySQL

mysqltutorial.org/mysql-find-duplicate-values

Summary: in this tutorial, you will learn how to find duplicate values of one or more columns in MySQL.

Data duplication happens because of many reasons. Finding duplicate values is one of the important tasks that you must deal with when working with the databases.

Setting up a sample table

First, create a table named contacts with four columns: id, first_name, last_name, and email.

Changing Favicons for node-red Dashboards

Dashboards created with node-red-dashboards all have the same favicon

You can easily change this by changing the icons in the .node-red/node-modules/node-red-dashboard/dist, but this change will be lost the next time you update node-red-dashboard.

To get a permanent change, add your icon as files icon64x64.png, icon120x120.png, and icon192x192.png to a folder of your choice, e.g. /home/nodereduser/.node-red/icons, where nodereduser is the user executing node-red.

Git Wars: GitHub vs Bitbucket

Introduction

Now, you might think the answer I'm going to give you is already obvious because I'm using GiHub right now, but it's not. Both GitHub and Bitbucket offer great Git services, but each has its own features and pricing plans. In the following... thing, I'm going to compare the two and then offer a final solution that should work for most people.

TL;DR: Both. Use GitHub for open source and public repos (you'll spend most of your time here) and Bitbucket for private repos. But, sign up for GitHub first, then import account into Bitbucket. Also, check comments for updates. P.S. I personally prefer GitHub.
