Make a dish based on Voronoi diagrams. Made an Inkscape extension (jim_voronoi.py) that does recursive Voronoi diagrams with optional Lloyd’s relaxation. Seed point layouts can be random or normally distributed from the edge, center, or two or more foci arranged about half way between the center and edge.
Plan is to make a nonogram outline, and do two levels of Voronoi regions. The first level is normally distributed at the edge, the second level is randomly distributed and has one round of Lloyd’s relaxation. Try several layouts, pick one that looks appealing.
Make the main color opaque blue. Cut with a tile saw, clean up on the grinder. Print out the design on two pages, tape together, and match pieces to the design to check while grinding.
Cut a base glass of 3mm transparent, place over the design, glue the tiles in place. Place paper over the glass leaving the main lines uncovered, use Bullseye True Blue Transparent power. Add Glastac glue to fix in place, remove excess, clean up. Mix Glastic Gel glue with powder, add to edge to give a border. Let dry overnight. Clean up some more, use vacuum to remove excess powder.
Mask main lines with blue tape, add Bullseye Aquamarine Blue Transparent powder to fill in secondary lines. Add Glastac glue to fix in place, clean up excess, and let dry. In places, the powder compressed when the glue was added–add more powder of both colors to fill remaining gaps, let dry, clean up. For detail clean up, hold the vacuum close by and scrap off excess powder / glue.

Aging Is Reversible—at Least in Human Cells and Live Mice: Changes to gene activity that occur with age can be turned back, a new study shows by Karen Weintraub “In living mice they activated the four genes (known as “Yamanaka factors,” for researcher Shinya Yamanaka, the Nobelist who discovered their combined potential in 2006). This approach rejuvenated damaged muscles and the pancreas in a middle-aged mouse, and extended by 30 percent the life span of a mouse with a genetic mutation responsible for Hutchinson–Gilford progeria syndrome.” “A damn stupid thing to do”—the origins of C. Today, C may be a lingua franca among programmers. This is its (abridged) history. by Richard Jensen
I found an online vendor selling cracked firmware that ignores the page counter chip and resets the internal page count to zero. The package came with a firmware image (V4.00.01.41) matched to the version installed, and download_0.bat, upgrade.prn, and usbprns2.exe
I ran into trouble–the firmware update wouldn’t take, it stalled when installing the image. So I downloaded the Samsung firmware updater, planning to replace the official image with my image (by changing the filename and putting it where the updater expected it. But the updater first updated the firmware on me (to V4.00.01.49), and then it wouldn’t use my cracked firmware because the cracked firmware was now an earlier version.
I finally got the firmware replaced.
Turn the printer on. Don’t hold down the orange “X” when turning it on, but press the orange “X” button immediately after starting it. The display jumps right away to “Wait Image”.
Now run download_0.bat and drop the firmware on usbprns2.exe. Now the firmware updated, then the printer reset. Worked!
Also note from the service manual: ‘Entering Tech Mode • Press “Menu > Back > Left > Right > OK > Stop” on the control panel continuously. The Tech Mode menu has an ‘F/W Upgrade’ option, but using it I couldn’t upgrade the firmware.

“Who Rises to the Top? Early Indicators”, pdf “A follow-up of subjects scoring above 180 IQ in Terman’s genetic studies of genius“ “Although there are numerous studies of gifted students, there have been no studies following up the very high IQ students into adulthood. Using the Terman files, 26 subjects with scores above 180 IQ were compared with 26 randomly selected subjects from Terman’s sample. Findings were generally that the extra IQ points made little difference and that extremely high IQ does not seem to indicate “genius” in the commonly understood sense of the word.”
Dichroic prism. A dichroic prism is a prism that splits light into two beams of differing wavelength. A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model.
