Fastest Server Stack Configuration for WordPress

There is no single fastest WordPress stack for every site, but the best-performing setups usually share the same shape: a lightweight web server, modern PHP with OPcache, full-page caching, object caching, tuned database settings, and a CDN in front.

VSCode: How to Set Working Directory for Debugging a Python Program

When a Python program behaves differently in VS Code than it does in your terminal, the working directory is often the reason.

Generating Matplotlib Graphs Without a Running X Server

If Matplotlib tries to use an interactive backend that expects an X server, your script may fail with display-related errors instead of producing a … Read more

Rounding a Datetime Value in MySQL to the Nearest Minute

When you store timestamps in MySQL, the values often include seconds even when your report, dashboard, or grouping logic only needs minute-level precision. Rounding a DATETIME value to the nearest minute is useful for analytics, event logs, scheduling screens, and any query where 2026-07-10 09:14:29 and 2026-07-10 09:14:31 should not be treated the same way. … Read more
