Took my Indian Parents to gourmet lunch and spent a bomb.
Mom: meh, no salt, no good spices, very bland. I want to leave.
Took them to dinner at Manoj Bhavan and spent 300INR:
Mom: Curd vada was really good, loved the set dosa.

Soft real time systems have probabilistic bounded nondeterminism, to simply put you say most of the time the system is predictable and if it’s not it can be forgiven.
Hard RT systems should be 100% deterministic. Your airbags should be deployed 100% of the time.

Our real time log streaming, video streaming and audio processing is not “hard” real time, we optimise for throughput, not deadlines.
Where in hard real time systems missing deadlines causes catastrophe - nuclear plants, industrial machinery, even airbags.

Airbags have dedicated microcontrollers programmed with bare metal code and hardware interrupts. Which means there is nothing between your code and the hardware, not even operating system if not RTOS.
They have redundant sensors, uses both hardware sensors and software

I don’t know whats the confusion here. Bi-weekly means twice in a week if I need something from you. Once in two weeks if you need something from me.
Don't say "bi-weekly", it's unclear. Better:
- "Twice a week", or
- "Once every two weeks".

The point of restarting computer is bring the ESC key back. Not to exit Vim.

Many systems use TMR - Triple Modular Redundancy, three redundant hardware systems and software to take vote on final decision in μs. They self diagnose themselves often, so if there is failure the system knows first & alerts user or stops the entire parent system if necessary.
