Quick React win: move static object/array props outside the component or wrap with useMemo(). Inline literals create a new reference on every render — silently breaking React.memo() and useCallback(). Three lines of refactor, real perf difference in large trees.

Анатомия чистильщика ссылок: как не сломать веб в Manifest V3

Каждый день мы делимся ссылками в мессенджерах, копируем их из браузера или кликаем по ним. И почти всегда к реальному адресу прилипает хвост из UTM-меток, fbclid , gclid и прочего мусора, которым маркетологи и платформы помечают наш трафик. Создать расширение, которое отрезает этот хвост с помощью регулярного выражения — задача на 10 минут. Но сделать так, чтобы это расширение не сломало работу сайтов, не убило поисковики и не вызвало бесконечные циклы переадресации в современных реалиях Manifest V3 — уже интереснее. Недавно я завершил работу над расширением ZeroTail и хочу поделиться несколькими неочевидными подводными камнями, с которыми столкнулся при реализации авто-очистки URL.

Je m'en sers de plus en plus souvent.

🔬🧪 Ah, the groundbreaking #discovery of how cells throw a temper tantrum! But wait, before you get to the part where science saves the world, you need to enable cookies, because apparently, even cellular biology requires a sweet tooth and a #JavaScript diploma these days. 🍪📜

I also enjoyed the technical part of creating this. With LLM help, calced got a python implementation with a nice CLI interface and JS version with a proper web UI. Both of them
- read the same syntax
- have no dependencies
- are contained in a single file (just download and run)

See this blog post for some thoughts on the process:
