Using width: 100vw in CSS and your page is showing a horizontal scrollbar because of it? Learn why viewport units ignore the scrollbar and see 3 elegant ways to fix this bug (using JS, cqw, or @property)
Every dynamic language crawled back to types. TypeScript buried JavaScript, Python slapped annotations on the duck, and AI hammered the final nail. I've been pushing strong types and DI since before it was fashionable. The duck is dead, and I'm not even pretending to be sorry.
PHPStan tells you that preg_replace can return null,
and you solve it by casting (string). Congrats, you just turned a
fatal error into a silent empty string. I'll show you why a loud error is always
better than one you don't know about.
I told Claude Code to turn off wifi. It did. Then I asked it to turn wifi back on. It couldn't — no internet. That one moment captures everything about this “everything agent”: it can code, organize files, analyze data, automate your work. Just never let it cut its own lifeline.
The === operator lets you sleep peacefully, but what about
< and >? There's no strict version of those,
and PHP takes the reins. I've prepared the definitive truth tables for PHP 8.x
and 7.x – no more guessing, no more test scripts, just find the intersection.
A step-by-step guide to getting Claude Code up and running — whether you prefer the desktop app, terminal, or WSL. Unlike browser-based AI chat, this thing actually edits your files and runs commands. Pick your poison, I'll walk you through all of them.
Working with time in PHP is fraught with pitfalls. See how the switch to
daylight saving time (DST) breaks DateTime and DateInterval objects, why
modify() returns nonsense, and how Nette Utils elegantly resolves
these paradoxes.
Most tutorials and linters force you to shove const everywhere you
look. But a constant that's only a constant by accident isn't a constant –
it's cognitive overhead. I explain why “prefer-const” is an anti-pattern
and why a simple let is all you need.
Empty string or NULL? This seemingly trivial question can break queries, JOINs, and the nerves of entire teams. I'll show you how to use CHECK constraints in MySQL 8.0.16+ to enforce one approach and put an end to inconsistency once and for all.
Directly renaming values in a MySQL ENUM is a recipe for disaster – data will vanish faster than you can say “backup.” The proper approach has three steps: extend the ENUM with new values, update the data, and only then remove the old ones. No magic, just common sense.
That's all. More articles are on the way.
