Don't all cars have service repair manuals that detail exactly how to take the mechanics apart and rebuild them should there be a need to fix some part of it?
Those are after market manuals and they don't exist for all cars. Auto makers like to keep as much information as possible proprietary for their dealerships so that you have to go there. Third party shops can usually pay to subscribe to (not buy) repair info and software updates.
They don't pay, you send collectors after them.
They still don't pay. You take them to small claims court... The circle of life is complete.
You have a right to know exactly what code is running in a machine you own, and how it works, down to every last freakin' instruction.
I don't buy that at all. Don't get me wrong here. I don't think it should be illegal to hack the software that resides on a device you own (though I would be curious if the farmer actually owns this tractor since they are usually purchased on long term loan agreements). But saying you have a right to know means that manufacturers have an obligation to disclose. I would be willing to bet that no one is willing to divulge to you in great detail how the mechanics of your car's engine runs, or how your dishwasher (lets say an old one not opperated by software) does what it does, or the hysteresis of your water heater. Nor do most people believe the manufacturers should be required to. Whether you could figure this out on your own or not is besides the point. And all this aside, I question the sensibility of what this farmer is trying to do anyways. He said it shuts down if a hydraulic sensor goes out and has to wait for days to get a new one. The more reliable solution would be to stock the sensors that go out most often. I would bet there is a pretty limited range of variants on the sensors. This is a lot safer than hacking the software of a multi hundred thousand dollar machine that would certainly void the warranty, probably violate the terms of any loan it is under, and possibly circumvent safety features.
"The Waterfall method has not been successful for 40 years"
What?? Every successful company I have ever worked for used and continues to use waterfall. Even for software. Clearly they are looking for a scape goat or, maybe more likely, have no idea how the waterfall method works in practice.
I've been working at Amazon for 6 months (after an acquisition) and I haven't yet heard of anyone asked to work on weekends.
OK. But could you please tell us how often you have worked on weekends or more than 9 hours in a day?
Just go with the flow control, roll with the crunches, and, when you get a prompt, type like hell.
