I can give you 2 pieces of information on this plan ... 1) It's well worth the time and effort, makes everything easier and more likely to be up to date and correct. 2) It probably won't go as smoothly as you like. We found that the engineer's drawings weren't nearly as organized as they claimed, and the results were mistakes and shop workers sitting around the engineering department while the engineers figured out where the drawings were. The result was also that engineering has gotten a lot more organized ;) They don't feel like spending 500 bucks for a new windows machine, so we figure we could just use our old computers for that. Makes sense. Most shop environments are hell on computers, and they'll have quite a short lifespan. They will also need some type of remote control, they were thinking that one operator would be in charge of connecting to all the computers and opening the webpage.

Re: manufacturing
I appriciate all the help from everyone. I just got off the phone with my supervisor and of course they changed their mind. Now they want all the computers to be able to look at different screens so that they can work on different jobs on the line. Makes sense, but that's not what they told the first time. But I guest that's just the way it works in the corporate world. I guess it's back to setting up a computers on every workstation with keyboard and mouse so that they can pull up their own stuff to look at. Again thanks. - Original Message - From: Chuck Swiger [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, February 06, 2003 10:02 AM Subject: Re: manufacturing Kenzo wrote: [ ... ] Are the factory workers going to interact with their workstations at all?

I doubt that will work, but if it does, I'd love to hear about it. The reason I don't think it will work is that engineering drawings on a computer screen usually require a lot of zooming in/out to be useful, and I don't know of any browsers that will give you that control. Although, you may be able to install some sort of image viewer that would do it. Yes our plan is to only have one person per assembly line controlling the computers so that they will all see the same thing. I would like to think that if we give them all control over the computers, they would only use it for work, but I find that people like to play around and see what they can get away with. True, but that's a _different_ problem. If they're slacking, they'll slack with other things than just the computer (although, experience shows that productivity will drop off for the first week or so until the novelty wears off). Besides, if you do a plain-jane install, once they've figured out that there isn't anything there to play with, they'll quit messing around. (i.e. don't install any games or anything) My experience also shows that the power they have to find the information they need without wandering around bugging bosses and foremen and engineers will save more time than they lose to solitair. We actually left all the games on the shop computers at the place I set up. It hasn't been enough of a problem to worry about. Actually, it probably saves time, because they spend their breaks at their workstations playing solitair, instead of going to the break room ;) Wandering over to ask a foreman or an engineer is a _huge_ time waster in my experience. In fact, one of the design goals of the system I created was to reduce the time that shop workers spend bothering engineers. At least when they're looking for it themselves, they're only wasting _their_ time, not the engineer's time. If you have a dedicated shop foreman, however, your situation may be different. This is starting to get off-topic. I'll reply off-list in the future. -- Bill Moran Potential Technologies http://www.potentialtech.com To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

In [EMAIL PROTECTED], Kenzo [EMAIL PROTECTED] typed: My boss just presented me with an Idea. And I realize that it's changed, and each computer will now be independent. But here's input anyway. He is more geared toward a linux box with redhat, but I would rather setup a computer with Freebsd that would do all the trick. what x-window manager should I use? I know KDE uses alot of resources, but what about gnome? I'd recommend plpwm (part of the plwm port). Have it configured with no keyboard shortcuts, or possibly one to relauch the browser. Launch the browser with .xinitrc. plpwm will automatically make it full-screen. They can then mouse around on it to their hearts content, but won't be able to do much else. Ratpoison can probably be used to do the same thing. It should be lighter than plpwm, but it won't be as easy to configure. what should I use for web browser? Well, I was going to suggest something with a remote feature like Mozilla, but that seems sort of piontless now. You might as well use whatever your webmaster recommends, which will probably mean either mozilla or netscape. mike -- Mike Meyer [EMAIL PROTECTED] http://www.mired.org/consulting.html Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.

People generally have reported better results with the Linux version running on FreeBSD with Linux emulation than the FreeBSD native version, but YMMV - many of the complaints about the native version concern the fact that there aren't FreeBSD versions of popular plugins, which is something you may not be at all concerned with.
