Most people were familiarwith desks but fewer understoodcommand line programs, so themetaphor made the basic operations acomputer could do simpler for peopleto understand and use.2.Predictability helps both the user touse the program and the developer tobuild and maintain it. A program thatdid different things at different timesfor unclear or no reasons is virtuallyuseless and impossible to fix orimprove.3.To communicate with the user4.Two times: it found the first pair, andthen the second, didn’t match the finalstar, and then performed thereplacement on both matches.5.The user needs to know whether thething he asked a computer to do wasunderstood, whether it has completed,and whether it was successful.Otherwise, he will not know whether itis safe or worthwhile to proceed. Aclassic example is a progress barwhile waiting for a page to load: userswill quickly become impatient andupset if they don’t know whether themachine is working or if it has stalled,and a progress bar is a simple way toreassure them.6.With digital media, all copies areidentical since they are composed ofdiscrete parts (usually bits). It ispossible to quickly detect and correctany flaw in the reproduction. This ispowerful because it means digitalinformation may be disseminatedbroadly and easily.7.‘Copy’ makes a duplicate entry of theselection in memory; ‘paste’duplicates the contents of the memoryto the selection. Both are copies ofdigital information.8.The temptation to replace the phrasewith the faster-to-type acronym for

Pretend it’s your term paper and it has to beprinted. How would you get around the problem thatthe computer and the printer aren’t printing?4.Describe a time when you “debugged” something inyour life(it does not need to relate to computers).5.Suppose your friend’s personal music player (such asan iPod) isn’t playing any songs. Explain the processyou would go through to debug the problem. List atleast eight questions you would ask, and explain howeach is an application of the debugging guidelines.6.Explainthe differences between fail-soft and fail-safe.7.Why is debugging a better approach than aimlessly“trying stuff”?8.List five questions you should ask yourself whiledebugging?9.Why do programmers never say theyare “down to thevery last bug”? Provide a concrete example thatillustrates this using HTML (your example should beyour own, not come directly from this book).10.Explain in detail three things you can try if you havefollowed the debugging process and are still unable tofix the problem.6.Fail-soft is when theprogrammingcontinues to operatebut with possible lossof functionality. Fail-safe is when theprogram stopsoperating.7.Debugging is a logicalprocess, “trying stuff”can lead to more bugsand fixing and unfixingthe same errormultiple times.8.Many possibleanswers.
