I have curated some fantastic reads for you this week. Let’s get to them!
This Week’s Picks
✔️ Database concurrency as simple as possible
#php #sql #database
I read this article I first discovered shared in the Symfony Station newsletter (one of my favorite newsletters that you should definitely check out).
There is good information in this article, explained in a simple way that is easy to digest for someone (like me) still learning the ropes on concurrency, using a sample bank account flow.
✔️ WordPress(dot)com vs WordPress(dot)org: Which Is Better for Your Website?
#wordpress
I must fully admit when I started blogging consistently over 4 years ago, I had no idea there was a difference between the .org and .com WordPress flavors. I've been on and stuck with .com for my site, Digital Owl's Prose.
However, I'm learning to install, use, and develop on the .org WordPress flavor nowadays. But, I don’t really have any plans to move off of .com honestly.
In this post from Kinsta, you'll find an in-depth comparison between these 2 WordPress variants with the pros and cons of each.
✔️ 🔥 🚀 30 Laravel Eloquent Tips
#php #laravel
I'm not even a Laravel developer (yet) as I mostly use Vanilla PHP and CodeIgniter 4. All I can say is wow! This is a list of tips to help work with the database layer through Laravel's Eloquent ORM.
What's even better than just a list of tips, is that each tip has example code and explanations.
If I were a Laravel developer, I would bookmark this one. 🔖
✔️ Transform NULL values with the MySQL COALESCE function
#mysql
I published this post on my Medium account here recently and enjoyed writing it. I think NULL can be one of those mysteries of SQL. But, the more you work with SQL and the database, the more you are exposed to NULL and start to understand what it is and what it isn't.
MySQL has NULL-specific functions you can use when dealing with NULL and the COALESCE() function is one option and is a powerful function.
✔️ WordPress Quick Reference
#wordpress #php
This is a resource page with links to common developer-related topics for WordPress developers. I love handy pages like this that just provide a useful resource for anyone to use and in this day in age of information overload, these types of resources are pure gold.
I want to create something similar for MySQL/PHP database operations. Could also be a great swipe file idea.
✔️ How to Upgrade MariaDB in Ubuntu 18.04 LTS
#linux #mariadb
Good article with step-by-step instructions on how to upgrade MariaDB. I like how this article includes an important step that a lot of people skip over; backup your database before you begin the upgrade.
Isn't there an old saying out there in the wide yonder that goes along the lines of, "You're only as good as your best backup?"
Words to live by...
✔️ Change Your WordPress Database Prefix to Improve Your Security
#wordpress #mysql #mariadb
SQL Injection (SQLi) is a real threat to any software using an SQL database and WordPress is definitely in this category as one of its critical and foundational pieces of core software is either MySQL or MariaDB. One method you can use to somewhat mitigate - but not foolproof - the potential for SQLi in WordPress is to rename the MySQL or MariaDB database table name prefixes.
This article by the WPMUDEV blog covers how to implement these database changes in a step-by-step plan. There are examples of sample queries for many of the tables you need to alter along with search queries to find other tables needing change as well.
