MySQL Index Tutorial: How to Use EXPLAIN, Composite Indexes and Speed Up Slow Queries

Submitted by jaypabs on

Your PHP or Python app was fast when the database had 50 test rows. Now the client has a year of real data, and the order history page takes several seconds to load. In most cases the fix is not a faster server or a new framework. It is one missing index.

Submitted by jaypabs on

Profile pictures, product photos, payment receipts, scanned IDs: sooner or later almost every PHP project needs a file upload form.

Submitted by jaypabs on

Sooner or later every Java program meets bad input, a missing file or a network that is down. If you do not plan for it, your program crashes with a long red stack trace, and in a capstone defense that usually happens at the worst possible moment. Exception handling is how Java lets you catch those problems, react to them, and keep the program running or fail with a clear message.

Submitted by jaypabs on

Almost every PHP project needs a login page: a capstone system, an inventory app, a school portal, an admin panel. And almost every beginner tutorial from ten years ago still saves passwords with md5().
