Another One Gone

Physicist Jack Goldman has died. Goldman was the chief scientist for Xerox Corp. In 1970, he was put in charge of California's Palo Alto Research Center, or Xerox PARC for short, purposely located 3,000 miles from Xerox headquarters. Goldman staffed PARC with top scientists to create new technologies, and they quickly churned out results. They invented the the first modern personal computer (complete with a new idea called a graphical user interface, through which the user would manipulate the computer with something developed with the Stanford Research Institute called a "mouse"). They invented the laser printer, and they networked their new "personal" computers with something else they invented: Ethernet. That's still not all: they developed InterPress, the precursor to PostScript, and object-oriented programming. They then showed their work off. Including most famously to a visitor named Steve Jobs.

Goin' Nutty Honey

Both peanut butter and honey have long shelf lives. I used to love mixing those for sandwiches and to put on crackers for snacks. Now that my gut is doing better I'm actually starting - carefully - to eat peanut butter again. So, my question is, what sort of shelf life would premixed peanut butter and honey have?

I've read that an opened jar of peanut butter is good for from three months to over a year, if it's kept closed between uses and away from heat and light. Honey, of course, lasts pretty much forever under those conditions. My assumption is that the mixture would last at least as long as the peanut butter, and probably longer.

Any corrections, additions, criticisms?

Rocketry

NASA has finally admitted the Saturn J-2 engine was a good one deserving further application and begun development on a new version:

Worksafe.

Space enthusiasts have been promoting this idea to NASA for decades. The J-2 was a fantastic engine in the Sixties and with modern materials and production technologies it will be even better.
