#ascii flow has gotten an excellent update. Great tool for #markdown drawings! asciiflow.com/#/

Stack Overflow just started limiting copying code from the site to 2x per user. The only way to get around it is to buy a physical copy switch from SO. Get ready for the entire web to crash.

We've renamed Stryker for JavaScript and Friends to 🥁🥁🥁... StrykerJS 🎉 It will save us valuable Twitter real estate. 😎 Note: this is purely a branding thing, the names of packages didn't change. See github.com/stryker-mutator/s… for reasoning. stryker-mutator.io/docs/stry…

Serious productivity boost for reading code on GitHub. 1️⃣. Go to any repo you are interested in on GitHub. 2️⃣. Replace "github" with "github1s" (one + s) in the browser address bar. 3️⃣. Enjoy browsing code like you would in VS Code. This is huge 🔥
