Grok 4.3 (Beta): The elegant, patented solution (and the one the patent US 4,197,590 is famous for) is to use XOR/invert mode when drawing the lines.
patents.google.com
You treat the plus sign as two full lines that include the center pixel:Horizontal line: XOR every pixel from left arm end → right arm end (center included).
Vertical line: XOR every pixel from top arm end → bottom arm end (center included).
Since the center pixel is hit by both operations, it gets XORed twice → it returns to its exact original value (XOR is its own inverse). All the other pixels in the arms get XORed exactly once → they invert (black white), so the crosshair/plus is always visible no matter what the background pixel color was.You never read/save/restore the center pixel, and you never have to special-case or skip it in your drawing loops. Just draw two complete line segments (or call SetPixel in a loop for each arm) in XOR/invert mode.This is exactly the “XOR cursor” technique the patent covers: you superimpose the cursor by XORing it in, and later erase it (or move it) by XORing the same shape again. The underlying image (including the exact center point you’re pointing at) is restored perfectly.

(If you were limited to plain “set to black/white” SetPixel with no read access and no XOR mode, the fallback would be to draw the four arms as separate segments that deliberately skip the center pixel. But that’s not what the patent is about, and it’s why the question mentions the specific patent number — the non-obvious-to-the-PTO-at-the-time trick was the double-XOR on the intersection.)So no, you don’t save the center and put it back later. You just let the math do the work for free. Classic “obvious in hindsight” software patent example.

Yes, unfortunately, It's out-weighed by my laziness.

@davepl1968 @FUCKINGRAZZI It's said that Tesla developed his OCD obsession with the #3 well into his 60s.

@FUCKINGRAZZI Howdy, howdy, howdy. It's like Sheldon's knock, always 3. I got it from the Shark in Toy Story when he's wearing Woody's hat. Stuck ever since.

Me: I often use grep in wsl or a search pattern in File Explorer to search for files. List other lesser known methods for both windows and linux.

@venedio @SarahTheHaider I've used a similar system since 2019. Dating and familiarization with find and grep on Linux and PowerShell (Get-ChildItem + Select-String), findstr + dir (classic cmd), and advanced windows search syntax in File Explorer assures that notes don't stay 'lost' for long.

I write notes in an electronic journal - not a book.
It is formatted by months. Each month is a separate file named like 'notes_2025.12.txt' and internally it has entries by days:
Dec 4
blah blah blah
Dec 5
I have thought about AI...
This has worked for me since 2010. I can use 'grep' on these files or put them into a search engine to find relevant stuff from the past.
I back up and encrypt the whole thing regularly.
