Its reason: The agency did not think Moderna compared the new vaccine to one of the best flu shots available. The company spent $750M+ on a 41,000 person study.

The gotcha with @property animating custom properties
Custom properties – even when registered through @property – don’t animate on the compositor.

Rah I wish I was the kind of person who can quote a 2010 study, and call it a day.
But my brain goes: it's been, 16 years ago, are those numbers still relevant?
So, anyone knows of some updated studies on cost of fixing defects, in design, dev, implementation, testing, post release?

In desktop mode it's basically a fully functional portable Arch-Linux laptop/miniPC - just add mouse/keyboard and a bigger screen if you like. #Steamdeck
