Random ramblings at the BBQ. Humans are wired to find patterns, even where there are no ones. Do not get superstitious. Embrace randomness. Coincidence is part of our life. Do not accredit it to some supernatural entity. It is nature we embace with physics, math and technology. A 6-digit one-time passwords (OTPs) with three or more adjuscent identical digits a couple of times a month if you are a heavy user of online payment systems should not worry you (and it is not a sign, even if it contains 666). On the contrary, if there were no such codes, something would not be truly random there. Randomness is crucial to our security. And because seeing is believing, let us generate some random passcodes.
Tip
Correlation does not imply causation.
Caution
A high correlation may happen by pure chance (this is known as a spurious correlation).
Tip
Coincidences are more likely than you think.
Note
Even an outcome which has a tiny chance of occurring becomes almost certain if you give it enough opportunities.

Don't worry. Just open the .ioc2 file in STM32CubeMX2 and hit the yellow button to generate the IDE project. Then open the project in STM32CubeIDE for Visual Studio Code and build it.

The old stock forecasting scam:
Send 10,000 people a prediction split 50-50 (half get "stock will rise," half get "stock will fall"). Next round, only the 5,000 who saw the "correct" prediction get another 50-50 split letter. After a few rounds you've got a tiny group who've seen nothing but perfect calls and think you're a damn oracle, at which point you upsell them on "premium insights."
After 7 rounds that group consist of 78 potential victims of the scam.

- Lavarand using OV2640 camera module
- Pixy2 camera and STS3215/ST3215 servo automatic dice roller/tester
Approximately 53%. It is then more probable to get one than not.
