Whiteboard interviews suck. The industry as a whole should have our tech interviews more representative of day-to-day development and @NoWhiteboardOrg knows it. We recently spoke to him about what that looks like, and how to improve hiring for all: piped.video/rLuM36vr0no

When it comes to creating informative developer content, @jamesqquick is a legend. We chatted with him what his content creation process is like, how to efficiently scale databases, and what serverless code is. Check it out: piped.video/AoWLJK71Cxc
CMSes are a critical part of the Jamstack story. What's more, they're immensely powerful tools to kickstart development for your very own SaaS platform. We were joined by @jamesperkins to talk about these very topics. Check out our conversation: piped.video/X2GodeR6bk4

A regex cheat sheet with quantifiers, pattern collections, and flags. While there's a larger cheat sheet at bit.ly/regexsheet (and an article that explains more), here's a few items the cheat sheet touches on. Quantifiers are how many items in regex an item is matching. "+" is "one or more" while "*" is "Zero or more". Pattern collections include a few characters to match at once. "[A-Z]" is "Any uppercase character from "A" to "Z". Meanwhile, "[a-z]" matches any lowercase character from "a" to "z"
