Origin of the Mac OS X Dock Poof Animation 

Chris Hynes:

On the piece of paper, he drew a series of frames similar to what is pictured above. A quick, five frame animation. The intention of the designer was that these drawings would stoke further discussion. That it would get cleaned up and refined later.

But that never happened. It shipped as is. And the rest is history.

Update: My pal CHOCK made these animations. When you look at the poof slowly, it really does look crude:

Speed it up, though, and your brain does the work of making it look good:

Same 5 frames, animated without delay.

CDC: Fully Vaccinated People Can Gather Indoors Without Masks 

Marisa Fernandez, reporting for Axios:

People who have been fully vaccinated against COVID-19 can take fewer precautions in certain situations, including socializing indoors without masks when in the company of low-risk or other vaccinated individuals, according to guidance from the Centers for Disease Control and Prevention released Monday.

Why it matters: The report cites early evidence that suggests vaccinated people are less likely to have asymptomatic infection, and are potentially less likely to transmit the virus to other people. At the time of its publication, the CDC said the guidance would apply to about 10% of Americans.
