So Naomi Brockwell TV blew my mind about how are smart TVs are spying on us with Automatic Content Recognition and other advertising profile scripts. Yikes!

I don’t have the resources to switch to a more secure streaming device yet (I’m gonna build one with mini PC running LibreELEC with Kodi hopefully).

In the meantime, I setup a Pi-Hole on an old Raspberry Pi 3B I had laying around last night to block as many ads and outgoing unwanted scripts as I could.

It is working great from what I tell! Even removed the ads from my Roku TV home pages lol! I’m sure some stuff is getting through, but at least it’s minimal.

Here is the PiHole install video I watched from Micro Center, but I also added SSH via private/public keys too. How to Block Ads Using a Pi-Hole With A Raspberry Pi

Oh and it has a built-in Star Trek NG LCARS theme!

Just for fun: how to fit squares of side length 1/n for n = 1 upwards in a 1 times π^2/6 rectangle (Basel problem). It's a bit tricky to avoid fragmentation of the free space left. It does not work with an initial square of sides π/√6 nor rectangles of dimensions π/2 times π/3 or 3/2 times π^2/9 (and I haven't proved it works up to infinity for my initial choice, left to mathematicians).

Heute kam das Kind (fast 8) früher als erwartet vom Filmabend mit seinem Kumpel zurück, während ich mit @lizzard gerade #Pi (Film von Darren Aronofsky) schaute und dann dachte ich mir: "Soll er halt mitschauen, sein Englisch reicht nicht aus, um viel zu verstehen und vielleicht nimmt er etwas Sprachmelodie mit."

Und dann kam die Verfolgungsszene mit der Kapitalistengruppe. Und ich hatte sie deutlich weniger heftig in Erinnerung.
Und dann wurde @lizzard im Tonfall so angespannt.
Und dann ist mir eingefallen, dass gleich eine nicht sehr kindgerechte Szene mit einer Bohrmaschine kommt.

Da habe ich dann doch lieber ausgeschaltet...

(Trotzdem toller Film!)

((Wir sahen dann trotz der späten Stunde noch eine Folge Avatar, damit er gar nicht erst über die Verfolgung nachdenkt))

It started churning out an endless string of zeros after the first 50 digits:

It was still going on printing the zeros when I started writing this post.

#python #Deepseek #Pi

I ran this #python code on #Deepseek:

import math
print(f"Pi is: {math.pi:.1000f}")

to see if #Pi can print with 1000 decimal places.
Answer:
"Python will print π (math.pi) with 1000 decimal digits. However, since math.pi is stored as a 64-bit floating-point number (IEEE 754 double precision), it can only accurately represent about 15-17 decimal digits. The rest will be filler zeros or incorrect digits due to floating-point precision limits.

Example Output (First 50 digits shown):"
