basically I've been appointed damage control and handyman for a restaurant…. it needs a lot of help.

my main concern right now is to install a network system with input terminals, ticket printers, credit card readers, cabling, and a nice database……

I'm capable of running the network configuration but I'm wonder what kind of software options do we have (besides micros and aloha) and what kind of hardware options (or suppliers) there are….
its a very simple Chinese restaurant.
one of the lowest volume restaurants I've been in. right now they hand write their tickets and do the books manually.

no liquor. no bartender
3 line cooks apps/fry, grill and sautée

1 credit card machine and line,
also with 2 phone lines.

only needs are a router, 1 comp for books and 2 for terminals (maybe 1 server comp?) and about 4 line printers
colinc ——– "approved setup the credit card companies particularly will refuse to deal"

perhaps if you have more info please email me

Do not under any circumstances shackle yourself with Micros, the least function able, piece of garbage on the market. We have it where I am and it just sucks. There is also squirrel, dinerware and another who's name escapes me that was the best I ever worked with. I will let you know the name of the other system tomorrow.

Also what type of restaurant is it, what type of system you will need will depend on what level of restaurant it is.

My school's computer lab is known for being infested with trojans and other viruses. Inserting your USB drive into any terminal almost guarantees infection.

I've taken to unplugging the network cable from the back of PCs and connecting it to my laptop in order to use the printers. It works great, but will this leave me vulnerable to viruses?

I haven't gotten any so far using this technique, but I just want to be sure.
I'm very conscious about having and using antivirus/antispyware/firewall software frequently and properly on my personal machines.

You shouldn't as long as you have a decent AV on your lappy. If you leave your lappy connected to the crippled school network for a while, it very well might happen, but for 2 minutes to print something; I really doubt it.

I made a live CD of ubuntu 7.10 all the basic things worked well. But then when I tried to actually use it you know like game get my all in one printer working I was like h4×0rz pwn j00! Junk.
Im not a fan-boy of apple,microsoft or linux.
But how can they call this superior?
ITS HALFED BAKED lot of good reading online ~positive~ about it lots of hype…..I just dont get it!
Is it suppose to be this complicated. more time in the terminal then actualy using it. Yes got beryl working cube junk!
Why do you like it?
Thanks.
XP easy
Vista easy
OSX easy
ubuntu or any number of the 1000000 different kinds OMFG! like 0.6% users?
I see linux excellent as a server. But not really for the desktop.
I did like open office but I can get that to work in XP and open office wont do any good in linux because of my all in one problem ;-(
Ok you lil noob! linux does get virues trojans and yes it does crash. now get your head out of the penguins bung!
again i fail to see the superior part about linux….1 it lacks support 2 no drivers for NEW things. 3 complicated. I just like one click not ~ lizard-wang dododod pee my pants-sudo. LOL

Versions of linux are based off the unix kernel - which is far more stable than anything Microsoft ever came up with. It is far more expandable and adaptable than Windows. A lot of your small to mid-sized commercial software is written for unix or linux based computers because they don't crash - they're running 24/7 with very little problems. A Windows NT environment had to be re-booted at least once a week to keep them going - not so with the unix/linux platform. This is because Windows doesn't block off memory spaces for sole use of applications - unix does - if an application in unix should crash - it doesn't affect anything else - you can kill that process and restart it - with nothing else bothered, no reboot necessary, etc.

Apple, to me is the best of both worlds - it uses the solid unix core underneath the OS X operating system, which is very user friendly, more so than linux - although once you spend some time with linux and realize it's power, you can have fun with it - it's sort of combination of PC and mainframe - if you will, which is the environment I work in.

I haven't tried the ubuntu version per se, but have used Red Hat and SuSe. I've also used the SCO OpenServer 5.5 Unix Enterprise version which the GUI was ancient-looking, but extremely powerful in its capabilities, for example, it'd run 64 terminal displays just for the console as a default on my system if I allowed it to.

For ease of use, I'd check out the Apple OS X - newest version is Leopard which is more pure in Unix than their previous OS X versions. Of course, you're stuck running it on an Apple - which I've become a convert to and will never buy another Windows PC again for my own use.
