It's even better if you can run the conduit from each point all the way back to a central location where you might keep your hub/server, etc. Try not to exceed 3 90degree bends in the pipe run, and I would use at least 3/4" if not 1" emt electrical conduit. A conduit bender is cheap at the hardware store, and the conduit itself is also cheap. Use setscrew type connectors(they are cheaper and less likely to come apart on you like compression connectors). Running conduit like this is a bit more expensive, and time consuming, but the benefit is that you will be prepared for any transmission medium that might become popular in the future. A set up like this will serve the owners of the home indefinitely... Cheers!
Plenum cable can cost twice as much and really only has one purpose relative to building codes.
Plenum cable is required when run in air plenums.
Commercial buildings will use the space above ceilings are "return air" plenums for heating venilation and air conditioning. Under these circumstances you should run Plenum grade cable for health/saftey purposes. In the normal home your cat 5 and other cabling runs behind walls so this is not an issue. Consider the romex cable that's used for the electrical wiring in your home, and your central vac system (another good idea to install while the walls are open)..these items are pvc. Forget the Plenum rated (teflon) coated stuff. It's a waste of money, and has nothing to do with "spreading fires" . It's about the gasses they produce when burning.
I built the networks that I administer.
I agree with the folks here that say you "don't" want to be an adminstrator. I am a programmer, and that is my first love. The trouble is that system administration takes away from programming time, and it's a thankless job to boot.
Systems admin is one step above telephone tech support in being a satisfying job. Sure you get the power of the systems, but you have to put up with whiners. That's what makes sys admins grumpy.
Sys Admin sounds like a lofty position, but it's really just living in utility.
I too got my real linux start on slackware.
Slackware was the first major Distro with MicroChannel support. Back in those days I had a lot of micro channel machines to use, and not much of anything else.
I always appreciated the direct and to the point aspect of Slackware. It would take me only minutes to configure any complex network/routing configuration, where as with RedHat I've wasted time in the past trying to get the needed routing/net configurations set up properly using their F**ked up GUI interface. I actually wasted a bit of time reading through the networking config scripts only to decide it was better to throw out everything and write my own, "straght and to the point/etc/rc.d/init/network" script
and simply not use their "over complicated, it doesn't work the way you want it to anyway" scripts. It was the only way to get the "route" and "ifconfig" entries the way I needed them. With Slack it was always a snap.
If I'm going to order a "pre-loaded" machine from someone like Dell I would rather have the OS that costs real money pre-loaded. That way I can set the machine up for dual booting, and load the free OS (*nix) myself.
Let's face it, Linux on the desktop for the masses isn't "no brainer" enough yet, if it will ever get there. If you can't load linux yourself, then you're probably not going to enjoy trying to use it.
That's great advice. The problem is that you can't stop your users from opening EXEs. I have yet to block EXE attachments from our mail systems. On the very day that I sent out an email warning all of our users not to open EXE, and other file attachments it was reported back to me that the project manager, my boss was opening Osama Bin Laden joke EXE's on his Windows machine. Sure I keep all the latest M$ patches in the NT workstations, and yes , I've been lucky, but you can't stop users from doing whatever the hell they want short of blocking email attachments.
There seems to be a whole new generation of M$ supporters that believe anyone that isn't building systems the M$ way is crazy. I work with a number of MCSE's, and have yet to talk to one of them that really understands systems the way a person with a Unix/Linux background does. *nix people seem to understand the M$ systems better than the M$ bred folks do.. I recommend that all M$ so called techies take a trip into the Unix/Linux world buy building and maintaining a *nix Server or two. It will open your eyes.
14 And it misleads those who dwell on the earth, because of the signs that were granted it to perform in the sight of the wild beast, while it tells those who dwell on the earth to make an image to the wild beast that had the sword-stroke and yet revived. 15 And there was granted it to give breath to the image of the wild beast, so that the image of the wild beast should both speak and cause to be killed all those who would not in any way worship the image of the wild beast.
16 And it puts under compulsion all persons, the small and the great, and the rich and the poor, and the free and the slaves, that they should give these a mark in their right hand or upon their forehead, 17 and that nobody might be able to buy or sell except a person having the mark, the name of the wild beast or the number of its name. 18 Here is where wisdom comes in: Let the one that has intelligence calculate the number of the wild beast, for it is a man's number; and its number is six hundred and sixty-six.
Even though the US objective is a little ambiguous, the objective is not to "overthrow" or "occupy" Afghanistan. The so called plan is to hunt down some individuals. Russia, and Brittan had more ambitious plans. This won't make the mission any less dangerous, or less difficult.

Just because a lot of money has been spent on a project, that is not reason enough to continue to spend money on that project.
It was a political toy that needed to go on the scrap heap. I for one am glad to hear Nasa have the sense to stop dumping money into at least some of the useless projects.
Maybe they'll put it up for auction some day and Gore can buy it and put it on his front lawn.;)
Does anyone else get the Nasa Channel?

I think eliminating launching that redundant piece of space junk was a good idea.
Also, the masses don't like to have to have too many choices, even if they do understand what they're looking at. This concept even applies to grocery stores. Stores that have a lot of different brands and varieties of products lose business because there is a large percentage of the public that can't handle the stress of having to make so many choices. The warehousing type of grocery store that has only one choice of peanut butter does well for more reasons than selling cheaper in bulk.
One of the reasons Micro$oft does well with the masses is because there are FEW choices, Bill Gates decides for them. They like it, and they want it that way.
Internet access in the workplace is a double edged sword. There is an incredible eroding of work ethic as a result. On the other hand I don't know how I could do my job in a prudent manner without it.
I feel that monitoring is all well and good, but agree more with the people that do it for resource concerns rather than busting employees.
If an employee is spending too much time surfing, than it's really a management problem. Managers should fit employees with a proper work load and evaluate them based on their performance on what's expected. Instead, many companies don't really know how to manage, so try and use monitoring as a tool to evaluate..
That's just poor management practice.
I think it's better to use traffic shaping to control resources, and content blocking for the
sake of legal problems in the workplace the company might come up against as a result of say one employee being offended by what another has up on their screen, and finally, send Managers to school to learn how to motivate employees to produce.
That's human nature. Other peoples problems aren't a concern until the same thing happens to me. The judicial system has been on the side of big business for ever, and probably never gave a thought to how people that work for those businesses feel about certain intrusions of privacy. I think it's kind of funny that it's happening to them, and they respond pretty much the way everyone else does.
I usually only bother updating when I build a new server.
If I like something about the new distro and feel it's beneficial across the board, I go ahead and bite the bullet, and update the other servers, otherwise I just leave them.
Geez, if it takes you a couple weeks to download the latest distro you'll never be able to keep up with Redhat upgrades. At Redhats accelerated release rate maybe we should just get CVS accounts with them and recompile weekly.
