Super moon night.
And now?
Moon Cake of course.
Harvest moon at any rate.

First moon pic with inexpensive telescope and handheld cellphone.
Going to get some filters (the physical object kind) and sort out a better camera thing.

Bonus - a woman at the lake(lady of?!?) helped me find and focus on Saturn at x60 magnification! Could just make out the rings.

Laurie Anderson Isnโ€™t Playing Games In the artistโ€™s studio, we played her 1995 Puppet Motel on a blue iBook G3 and talked about technology, cyberspace, and abstraction.

โ€œWhen I was a kid, I went to school and instead of saying goodbye, my mother would say, โ€˜Win.โ€™ I was like, โ€˜Win, what?โ€™ But thereโ€™s always a contest. I didnโ€™t want to be involved.โ€ โ€”Laurie Anderson, musician and artist

Snippet of a tree graph of the Soma Cube.  
Background - spreadsheet entries the tree graph is generated from
Foreground 1 - yellow squares that represent a branch in the tree with black  lines going out to smaller yellow squares with numbers in them.
Foreground2 - mostly along top edge, 3x3 array of concentric circles, colored to represent different layers of the cube and which piece is situated in it.

Air dry clay math fun. The "amplituhedron" (not to scale, yet) of a simple four piece tiling puzzle called SIXL(six unique tilings).

Eventually You're Going to Have to Stand for Something On accepting the fascist offer and being better than Ezra.

I wrote about why the regrettable conclusions of Ezra Klein pissed me off so badly in the last couple weeks.

On moral cowardice in an era that calls for clarity, and a popular political instinct to try to solve divisions of abuse by ignoring causes. www.the-reframe.com/eventually-y...

The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six regular hexagons around a central hexagon. All seven hexagons share the same composition and have 4โ€ sides. The first image along the bottom shows a scaled-up kite which is used to create the regular hexagon (with 4โ€ sides) shown in the second image. The kite is made of 2 blue rhombuses, 2 gray darts, and 4 pink triangles. The three images on the right show the progression of the design.

emergency clause is open-ended, interpreters should emphasize
context and purposes to give intelligible meaning and scope to the
clause; and second, the means must fit the emergency ends. Congress expects emergency powers to be invoked when immediate
action from the President is necessary to effectively respond to a
disaster or crisis reached by the statute; Congress never intended
emergency power provisions to aggrandize the reach of presidential power past the intended reach of a statute. Thus, when an emergency power is invoked, it should typically be permissible only if it
does not conflict with statutory purpose. When a President invokes
a statute to support action that does not align withโ€”or runs directly
contrary toโ€”statutory purpose, that is evidence of an abuse of
power. The language, legislative history, and historical context of a
statute may shed light on its purpose.
This approach would serve as a solution to both problems: First,
