Early Arduino were all AVR 8-bit, at the time it was already on the way out. There were no shifts in industry to those chips.
People who got Arduino, either:
- blinked some LEDs and forgotten about it
- switched to esp32 and/or stm32
- esp32 and esp8266 move is funny because people started buying esp8266 to add Wi-Fi to their arduinos and then realized that they can just throw away arduino all together.
- switched to cheap clones that offer more
- quick connect for that not only want to blink LEDs, but also have some cool graphs to look at (like temperature and humidity)
- boards that specifically designed for their use case (i.e. battery and eInk connectors and circuitry required)
Arduino is inconsequential to industry as whole or even to hobbyist using it.
Regarding the turbofan and [0], above...if you're communicating to a non-engineer (me), how does the design get to the point of such complexity? I would love to learn the design story behind such an incredibly complex piece of machinery.
For the same thrust it's more efficient to accelerate a large mass of air a small amount than t accelerate a small mass of air a large amount. The fan is what gives you that.
I rough guessed the cost of fuel over a 737's life as $150 million. Where the engines cost something around $30 million. That pushes the engineering economics towards maximizing the engines efficiency.
I'm suspicious that bypass ratio's for turbofans are close to maxed out. The diameter of the fan gets unwieldy. That was the design issue that the 737 Max was trying to get around. With bad results. Possible the future is hybrid designs with two engines and 4 or more electrically driven fans.
I'm no linguist, but the question does seem unambiguous, or quite clear, to a reasonable observer. The context is "voting in a US election" AND the subject is "an illegal immigrant" WITH an assumption that the illegal immigrant has, in fact, illegally emigrated to the US.
I love that you include the BNF-ish grammar. Grammars are so straight-forward to read, I wish my eyes didn't glaze over during those times I've tried to sit down and create one.
