Some of the other machines I've had to deal with haven't been so obvious. (E.g., the "shoebox PC" that I mentioned also had bad caps. It is considerably harder to service than most Dells due to its small size and "proprietary" mechanical design.) >>> It has 3, 35 GB hard drives, but the 'Server 2000' was deleted.

I.e., I only run my servers because I want long term reliability (power supplies and spindles). Most of my regular work I do on consumer grade machines. Servers tend to get reliability at the expense of noise and size. :<

When I was first getting back on my feet after the two years I spent stuck in bed, I did some things that made people question my sanity. Like hanging a plastic grocery bag from a hook in the ceiling, to force me to stand and stretch every time I had a scrap of paper to throw away. Other than one screwdriver, all the hand and power tools went back out to the shop building, so I had to limp out there for every little job. -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

Oh, and it cannot be a Windows newer than XP because they broke legacy support after that. [...] -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

It free up desk space where I work on computers, as well. It will give me some experience with newer networking software & hardware. I do some voluenteer IT work for non profits, and their old junk is dying. I just pulled a dying Cisco 1924C-A and had to replace it with a Linksys EZXS-88W unmanaged switch. It doesn't inspire confidence when you discover that it's also sold at Toys-R-Us. http://www.toysrus.com/product/index.jsp?productId=2539349 -- Anyone wanting to run for any political office in the US should have to have a DD214, and a honorable discharge.

Yes, it is a "point of contention", here. :< Running any of the servers is a real b*tch -- I think there's just a regular desktop PC in there -- along with a 2KW resistor wired across the mains! :< Most of the time, my electric needs are probably *below* the typical PC user (on an hourly basis) as I use X Terminals for much of my software development (the applications -- the *clients* -- running on the basion host -- which is running *anyway*). But, when a server is running, the electric meter gets a good workout! :< I am currently (as we speak) tearing down one of the servers in favor of a desktop machine -- more MIPS, fewer BTUs. But, that means the server runs while I am pulling things off it... This must get done before it gets much warmer! (We've, so far, managed to avoid turning on the ACbrrr... but that won't continue to be the case with this pig running all day!) >> You can get around this by using "hosts" files (which is a >> maintenance headache) *or* force everything to deal with >> SMB/windows style names/protocols <frown> > > It's all automatic over here.

Oh, > and it cannot be a Windows newer than XP because they broke legacy > support after that. Yup. I use Windows (2KS and XP) for anything that needs "expensive tools" (CAD, PCB, DTP, etc.) and NetBSD & Solaris for everything else. Since the "everything else" tends to take far more time than any of the other activities (i.e., I can design and layout a board in 10% of the time that it will take to write the firmware *for* that board!), I spend most of my time away from Windows. OTOH, I spend more *maintenance* time on the Windows machines than any other! :< |
