Smart Thermostat


This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.

This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.

Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.

Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.

Please do not email me about this project without reading the disclaimer above.

We are trying to make the earth support four times as many people as it can sustain. This application tries to discourage people from having babies. The heart of it is an electronic carnival wheel you spin to find out just what sort of baby you will have.

As a separate exercise you want to estimate the costs of raising this child, and what else you could do with that sum of money. Another set of questions are of the form, Will you be able to stand by your child if it turns out they have such and such a problem. e.g. teen pregnancy, drug addiction, severe accident leaving disabled. Are you strong enough to deal with that?

You will have to explain what the wheel means. Each spin is just a simulation of the odds of various things happening. Just because it showed happy results does mean you results will be happy and vice versa. You have to spin the wheel a few dozen times to get a feel for what sort of chances you are taking by having a baby.
