Steve Jobs about OOPS- As simple as that

What are objects?
Jeff Goodell: Would you explain, in simple terms, exactly what object-oriented software is?
Steve Jobs: Objects are like people. They’re living, breathing things that have knowledge inside them about how to do things and have memory inside them so they can remember things. And rather than interacting with them at a very low level, you interact with them at a very high level of abstraction, like we’re doing right here.
Here’s an example: If I’m your laundry object, you can give me your dirty clothes and send me a message that says, “Can you get my clothes laundered, please.” I happen to know where the best laundry place in San Francisco is. And I speak English, and I have dollars in my pockets. So I go out and hail a taxicab and tell the driver to take me to this place in San Francisco. I go get your clothes laundered, I jump back in the cab, I get back here. I give you your clean clothes and say, “Here are your clean clothes.”
You have no idea how I did that. You have no knowledge of the laundry place. Maybe you speak French, and you can’t even hail a taxi. You can’t pay for one, you don’t have dollars in your pocket. Yet I knew how to do all of that. And you didn’t have to know any of it. All that complexity was hidden inside of me, and we were able to interact at a very high level of abstraction. That’s what objects are. They encapsulate complexity, and the interfaces to that complexity are high level.
I have made a custom board with Atmega328P SMD IC and now I am having a problem flashing it. I have flashed multiple chips like these earlier, however this time I am having a hard time figuring out the issue.
I am using Arduino UNO as an ISP programmer to burn bootloader but getting responses like Attempt 1 of 10 - stk500() is not responding etc., like that. I need some help regarding this issue.
Any kind of help will be greatly appreciated. Please ask me for any additional information that I might have not mentioned in this post.
Thanks in advance.
I have been facing this problem recently while I run the program the output terminal just shows scanned text and the android virtual device is not opening. I have reinstalled the SDK but the problem still persist.!
Hi, I was looking for a reliable carbon monoxide sensor, I tried the MQ7 sensor, but it has a preheat time of 48 hours and a sensitivity range from 20ppm-2000ppm, and my application requires 1ppm to 1000ppm. let me know if anyone working with a similar sensor or use case!
@milanvarghese No, the battery comes into the play only if there is no power from the solar cell. It's like inverters in our home. They activate only if main power is gone, rest of the time they keep charging. similarly here the direct power will be coming from the solar cell, only if the solar cell can't produce enough voltage battery comes into the loop and starts providing voltage to our circuit.
@kowshik1729 I have seen this, but doesnt it damage that battery? dischargeing and charging at the same time?
