What’s the difference between ordinary functions and arrow functions in JavaScript?
Arrow functions (also known as ‘rocket’ functions) are concise and convenient. However, they have subtle differences compared to function declarations and function expressions. So how do you know which one to use, and when?

JWTs Are Not Session Tokens , Stop Using Them Like One
When JSON Web Tokens (JWTs) hit the mainstream, they were hailed as the solution to everything wrong with session management. Stateless! Compact! Tamper-proof! Suddenly, everyone started stuffing them into every web app like ketchup on bad code.

AI coding tools make developers slower, study finds
Artificial intelligence coding tools are supposed to make software development faster, but researchers who tested these tools in a randomized, controlled trial found the opposite.

Episode #518 - Password Managers
#Tip of the day (and something I just developed and tested some minutes ago): you can hide the anime-esque "catgirl" picture of "Anubis" (as in that open-source project that acts as a "Man-in-the-middle" (more like "Catgirl-in-the-middle") against DDoS and crawling activities by using the same mechanisms behind cryptojacking) using the following uBO (uBlock Origin) filter (possibly compatible with other adblockers as well, such as ABP):
/.*/##img:matches-attr(src=/(happy|pensive|rejected)/)/.*/ matches all domains (because "Anubis" can be lurking behind any domain), ##img:matches-attr() matches image (<img>) elements which matches a specific attribute, which is src, to be compared against a RegExp expression, /(happy|pensive|rejected)/, which contains all possible image filenames for Anubis's states ("happy", "pensive" and "rejected"). robots.txt. Anubis, just do the cryptojac... I mean... the "Proof-of-work computations". There's already text stating whether the request was approved, rejected or undergoing evaluation, so there's no need for any images... Yeah, I'm boring.🔍🎨 Oh great, yet another #tool promising to #revolutionize your life by letting you play detective on #Android apps—right from the comfort of your bloated #VS #Code. Because clearly, what every developer needs is more #plugins and AI suggestions to fuel their #existential #crisis. 🙈💻
