#PiDay is already over; however, here's an interesting and quite entertaining article explaining why #NASA only uses a tiny fraction [sic*] of Pi's infinite decimal places.

Even for its most accurate calculations, which are for interplanetary navigation, NASA's Jet Propulsion Laboratory uses 3.141592653589793.

* I find it amusing that they really say “a tiny fraction” - because mathematically, a tiny fraction of an infinite number would still be an infinite number.

NASA JPL EducationHow Many Decimals of Pi Do We Really Need? – News | NASA JPL EducationWhile world record holders may have memorized more than 70,000 digits of pi, a JPL engineer explains why you really only need a tiny fraction of that for most calculations – even at NASA.

A couple years ago #NASA had an article answering a common question about how many digits of pi they use for their calculations. While pi can be computed (with ever-increasing amount of effort) to almost any number of digits, for navigation of space probes they only need 16. https://www.jpl.nasa.gov/edu/news/how-many-decimals-of-pi-do-we-really-need/ #PiDay #space #math #astronomy #tech

Happy Pi Day!

Dinner is served.

Chicken leek and mushroom pie, with my no fail pie crust.

A small individual ceramic pie plate with a beautiful golden brown pie that has two leaves on the top. Beside it is a wooden bowl with a green salad. They are sitting on top of a black slate plate.

A dark, cloudy, city night. The sky is heavily overcast; the whole scene is an oppressive brownish gray. In the foreground, a figure stands on the roof of a building. The figure is in an action pose, as if they're ready to leap into the sky. A low fog surrounds them. They have a Greek letter "pi" on the back of their outfit, and two squarish horns on their head. Hovering in the sky, projected against the clouds, is a ghostly greenish spotlight that also has a Greek letter "pi" at its center. In the distance are other skyscrapers, the windows dimly illuminated in the fog. The painting is signed "Chris Silverman".

I really, really love decorating pie.

An uncooked pie. The top is an intricate lattice with strips of varying width. Each direction has a braided strip. Around the edge are leaves and various berries. The pie has been given an egg wash.

Hand drawn generative/procedural art in ink on an open page of my sketchbook. The abstract pattern looks like a string of beads. My glass dipping pen is next to my sketchbook.

(Oh, Happy Pi Day! I'm celebrating by trying to get my rPi online lol)

Using a package manager... is kinda more chill than searching online for the program, downloading it, unzipping it, installing it,
dealing with Windows bitching about it being dangerous because its not from the app store, and THEN using the program.

I legit have Linux on the Brain.

Trying to get my Raspberry Pi up and running (PiHole). It needs an IP address via DHCP.
So I'm sitting at my Windows computer, cursing the fact that this tutorial is using Windows 11 with PuTTy. At My Windows Computer.

Then I ask myself... well damn how do I install PuTTy via package manager on Windows?
...

Listen my brain is having a rough time these past few months. (I've done this before but I forgot.)
