httpd.conf is Apache's main configuration file — but on a server hosting more than one site, the real day-to-day editing happens in per-site virtual host files, not the main config directly.
One line in Angular's router config switches URLs from /#/products to /products — the part that actually takes real work is configuring the web server to make those clean URLs work on refresh.
Anything slow that doesn't need to finish before the response is sent — an email, a report export, a third-party API call — belongs in a queued job, not inline in the request.
Ubuntu's default repositories only ship one PHP version at a time — the Ondřej Surý PPA is what actually enables running several versions side by side, switched per-project or per-CLI-session.
Three separate php.ini directives all cap upload size independently — raising only one of them still leaves the request blocked by whichever limit is lowest.
APP_DEBUG in .env, why it must always be false in production, and what actually leaks when it is left on by mistake.
The one crontab entry that runs everything, why it must fire every minute, and how scheduled tasks are actually defined in Laravel 11 versus older versions.
Laravel caches five different things separately — config, routes, views, events, and application data — and clearing one doesn't touch the others.
A working LAMP stack setup for Ubuntu — apt package installation, the Apache/MySQL services, and the one phpMyAdmin config step people usually miss.
Three real approaches — virtual host document root, a root .htaccess rewrite, and symlinking — with the tradeoffs that actually matter for picking one.
