Attempts Average/5 6. How to start building a sustainable low-waste society In ecosystems, the waste outputs of one organism become the nutrient inputs of another organism, so all earth's nutrients are endlessly recycled. In ecosystem, this principle of sustainability is also seen; instead of organisms, however, the wastes of one product become the raw materials for another product.

Advancements in software engineering stem from what four improvements in the industry? 1. What is 'arithmetic overflow'? 2. What is considered to be the most obvious approach to making sure a program has no bugs in it? 3. 4. When we consider the proper education of software developers, what subjects do we consider they should learn? 5. What are the major tasks of the software development process? 6. What is frequently regarded as the important aspect of software development (also considered to be the basis of \"Brooks' Law\")? 7. What are the three criteria that professor Douglas Birsch says must be met for a person to bear moral responsibility? 8. What is the relation between the software in the Therac-25 and the software in the Therac-20? 9. On election night in Florida in the 2000 election, the discrepancy between exit polls and the actual reported count was particularly large. One reason was that many ballots were declared invalid due to an incident that dealt with \"hanging chads\". Had the Florida ballot been recorded and counted electronically, there could not be any problems with partially detached chads. There could, of course, be problems with the electronic recording and counting. Would recording and counting the vote electronically be superior to the punched card ballot? Express your opinion among your classmates.
