CSS has a new feature, "text-wrap: pretty" and if you're a paragraph reading this don't give in to the W3C's beauty standards you're beautiful just the way you are dangling orphans and all

If surgeons had dev tools:
mid-surgery, elbow deep in guts "This spleen is a mess. Who last touched this? git blame... oh. Of course. Me."

I'm starting a new podcast where two people meet to bake pastries and talk about relationship issues. It's called "Mixed Feelings"

Tbh more surprised it doesn't say daemons

Hell hath no whammy like a furry scorned

Brilliant! It's even rendered in purr-spective

Ghost-in-the-machine type issues are the worst :(
Happy to help brainstorm-debug the issue with you

Most of the developers I work with these days have never known the solitude of playing Solitaire on a computer that doesn't even have an internet connection

I haven't written database queries in years but I picked it up again super quickly. It was just like riding a bySQL
