in order of rising importance I guess that this caused the DDF spike "Former Secretary of State George Shultz dies at 100"

note that it is about 4000* more then all surrounding dates. i think this might be a bit flip  (cosmic or otherwise)

To explain a bit better, the number 797 would be represented in binary as 0000001100011101,
if you flip the 4th bit from the left you get 0001001100011101 which equals 4893 (the number of users (supposedly) online listed for Feb. 8 2021)

here they are lined up:
797    0000001100011101
4893  0001001100011101

The reason I think the real number is closer to 800 is because looking at the surrounding dates the number of users is about 800 and no other stats (such as new members new posts page views etc.) on Feb. 8th are that different then surrounding dates. The articles I linked to explain some circumstances that a bit flip can occur.

For those who still don't understand @notyettaken 's wise words, see Chat GPT's explanation:


Let's break down the basics of binary numbers and how bit flips can affect data.

What is Binary?

Binary System: This is a numbering system that uses only two digits: 0 and 1.
Base-2: In binary, each position represents a power of 2, starting from the right.

How Binary Works

Binary Digit (Bit): Each 0 or 1 in a binary number is called a "bit."
Binary to Decimal Conversion: To convert binary to decimal, multiply each bit by 2 raised to the power of its position (starting from 0 on the right), and then sum the results.

Example:

Binary: 1101
1 x 2^3 = 8
1 x 2^2 = 4
0 x 2^1 = 0
1 x 2^0 = 1
Decimal Equivalent: 8 + 4 + 0 + 1 = 13

Bit Flips

Bit Flip: This occurs when a bit (0 or 1) accidentally changes to the opposite value.
Causes: Bit flips can happen due to issues like electrical interference or hardware malfunctions.

Example of a Bit Flip

Original Number (Decimal 797):
Binary: 0000001100011101
Flipped Bit: If the 4th bit from the left changes from 0 to 1:
New Binary: 0001001100011101
Decimal Equivalent: 4893

In Your Scenario

The number 797 was accidentally changed to 4893 due to a bit flip.
Given the surrounding data, 797 is likely the correct value, and 4893 is probably an error.

Don't know what you do, but I'm going to guess you're mid 20's, married about 2 years, Canadian spouse, recently (within a year?) got your first house. Part time kollel, part time ?
