Adobe Flash was the language of choice for a generation of game developers, helping kickstart an indie revolution on the still-young web of the 1990s and 2000s. But it withered on the proprietary and insecure vine, and both web browsers and Adobe have now canned it, threatening countless games and interactive presentations with the memory hole. The Internet Archive comes to the rescue, not only archiving the flash files but emulating the player itself, allowing history to live on.
“The Internet Archive has begun emulating Flash Animations, Games and Toys in a new collection,” wrote archivist Jason Scott on Twitter. “It’s at https://archive.org/details/softwarelibrary_flash and it’s going to be past 1,000 items in 24 hours. You can add your own and get them running, and the animations have never ran smoother or better.”…
From our friends at Boing Boing: “Internet Archive turns on Flash emulation, already has 1000 items to check out.”

As we celebrate that what’s old is new again, we might recall that it was on this date in 1915 that Albert Einstein presented the Einstein Field Equation to the Prussian Academy of Sciences. Einstein soon after elaborated it into the set of 10 equations that account for gravitation in the curved spacetime that he described in his General Theory of Relativity; they are used to determine spacetime geometry.
(German mathematician David Hilbert reached the same conclusion, and actually published the equation before Einstein– though Hilbert, who was a correspondent of Einstein’s, never suggested that Einstein’s credit was inappropriate.)
“If it was so, it might be; and if it were so, it would be; but as it isn’t, it ain’t. That’s logic.”*…

On the right side of the equal sign, the distribution of matter and energy in space; on the left, the geometry of the space, the so-called metric, a prescription for how to compute the distance between two points.
