Absence of fear, perhaps plays some part, but only on a basic level. For instance, while I was a computer technician working on high voltage display tubes I had a big fear of getting zapped. This fear was a healthy fear, because it made me make sure I took of my watch and any other jewelry that would attract electrons. The reason why I did get zapped was I was not careful. I was more careful there after. Things like taking the plug from the wall before I put my fingers in a box were also second nature because I was zapped. In software I really do not have the same fear. It can not zap me the same way. The fear thats I do have is losing hours and hours of work. We do back ups nightly on our machines because of this. When working as SU, I also have fears. Fears like I might type in the wrong device name when making a new file system on a disk. This causes me to be very careful, and to review each command line before hitting return. Recently we got one of the new Vaxstation 2000s, and I put Ultrix on it. I found out that the floppy disk drive was called rx. So I wanted to back up some info on it. I said "tar cv /dev/rrx0a". It so happens that DEC, inspite of labeling their hard drives "rd", also label them "rx", so rx0a was really rd0a. Needless to say it destroyed the root file system. I managed to destroy the root file system again when trying to boot from a floppy I created. The floppy had enough on it to load to a certain point. All I wanted to do was to see if it would work. There must have been something in rom that it triggered, and the computer wrote on the hard drive. If we didn't have to borrow a MicroVax to build the system with, I wouldn't really care. I now fear that anything I might do, might destroy the root file system. Thus I will limit the activities I will do on that machine. That is until we get a better way to rebuild the OS.

The only problem here is that your fear of get shocked had a very real basis. For most people who fear computers this is not the case. I work as a consultant on the campus network. While I do occationally get questions from experianced users who need to know some fine or obscure detail of the system, most of the people I help are new users with little or no knowledge of computers. The biggest single problem that most of them have is an irrational fear or distrust of the machine. In turn, most of this fear is simply due to the fact that it is something new to them. They jump when it beeps at them because they feel that it is yelling at them, they are afraid that they will mess something up, ect, ect. Helping them overcome this fear is basically a matter of boosting their confidence. No, it's not yelling at you, it's asking you for help. You can't mess anything up at this point, and so on. Showing and explaining that it isn't some monster out to trick them and eat their grade, but a tool to be used helps to remove some of that fear. As for the general discussion, I do think that this fear is a very big part of the difference between the computer literate and the computer illiterate. Once they start to overcome this fear there are still steps to go through. On a pragmatic basis, I draw the line at the point where people start using the online or printed manuals first before they come running to a more experianced user or consultant for help. At that point they have developed enough self-confidence and knowledge of the system to further their own knowledge. I think that this really is a form of literacy. Learning to understand a manual page definately requires a knowledge of an other language (especially a CMS help file :-). In addition, simply coming to understand the syntax of a system's commands is a language skill. I have had considerable success simply explaining that a command is a verb, sometimes it requires an object (the filename or pathname) and that the options are adverbs. The only real problem is that most (all?) operating systems that I am experianced with have the modifiers (the adverbs) separated from the verb and following it. This seems illogical to most English speakers when they first encounter it, since English uses pre-positions in most cases. Does anyone have experiance with teaching users whose first language is predominately post-positional? Do they find it easier to understand, say, UNIX command structure? Vnend
