never buy hardware from these guys:

totally incompetent and hiding behind an ineffective support website.

Okay so I've almost convinced myself to spend a lot of money on a new machine.
A lot of money being $250.
So basically I'm looking for a new motherboard, chip and memory.
and at least 1 non sata controller so I don't have to buy drives too.
I go to tigerdirect and I'm overwhelmed by the information overload.
I decided to go with the tactic of pick the features that have the most options available.
So I want socket 775?
I want ddr3/ddr2 memory?
It's obvious but never occurred to me before that a 32 bit chip can only address 4 gig, so I'm going to post modern and get a 64 bit chip.
I figure I can get tons of memory and run a bunch of VMS of 32 bit oses if I need to, each one getting 4 gig.
Do I want an intel chipset? Do I want nvidia chipset?
And what the hell kind of chip do I want?
It's going to be running linux, so I imagine more cores is better?
After I pick intel chipset, there's options 945G, P45, Q35, G31 and x48.

It doesn't even give me a clue WHAT THESE OPTIONS ARE FOR...

But there's 12 options for p45 so I picked that.
Do I want asus, gigabyte? biostar? Didn't they go out of business?
This is all very confusing.

Nothing wrong with NVidia chipsets. Also nothing wrong with the older P/G35 chipsets if you don't need PCI Express 2.0 (and who does?)

Are you looking for discrete graphics or are you fine with integrated graphics?

Since I don't know what those are, I expect I'll be happy with either and would probably prefer the cheaper.
The most video intensive thing I'm ever going to do on this machine is watch a DVD in a VM window. And I'm probably never going to actually DO that.
What I'm more interested in is a lot of memory slots and large max memory possible.
Although from what I've seen, the biggest board I could find supports only 16 gig which admittedly I don't need right now, but most only support 8 and that's kinda sad to me.

I just noticed there's an amd64 install of ubuntuand an i386 but no mention of intel64bit.
Is there such thing?

no, intel had the itanic, which spoke (well... speaks? IG, how many of these are idling around in your customers racks?) IA64 which never realy took off, since windows won't run on them in an acceptable speed... (just if you boot them in "i386 emulation mode") so, AMD came up with something on their own, more compatible way, which then was called AMD64 which intel licensed and sells it as "em64t"

right, I had forgotten, but don't go all getting on Intel's case. THey build a genius architechture, they just didn't design it around windows, but it was fucking brilliant. The compatibility mode was so that it would run windows, so of course it sucked, but pointy haired bosses have no appreciation of good design just of what runs windows.
But things being what they are, I guess amd is the way.
Do they make linux build for ia64? That would kick ass.

Yes, you can run Linux natively on an Itanic. It runs about as well as it does on any other architecture, even though there's no compelling reason to actually buy one. Optimizing for Itanic requires special Intel compilers.

dothebart: since it's largely a colo facility, I wouldn't know if some customer somewhere has an Itanic or three stashed in their racks, but ... I personally have never seen one. Plenty of AMD and Intel, a bit of SPARC and the occasional POWER box, but no Itanic.

Ford: just buy a pre-built system. There isn't a lot of money to be saved by rolling your own anymore.

Here's something maybe people can help me out with here. My house, with 3 adults and 4 children living here, has 6 computers in general use, as well as a couple of general purpose computers. I need to come up with some kind of strategy to back everything up on a semi-regularish basis. How would someone go about doing something like that? We've got probably around 750GB or so of total storage, spread across a ridiculous amount of hard drives (at least one in each computer, some have 2) .. and I just really don't have the slightest clue as to what would be a good way to handle this sort of thing. I pretty much use the "The Internet Is My Backup" excuse for most everything I personally have, but after having one of the computers getting a terribly nasty virus that required re-formatting fresh, and a hard drive failing requiring replacement, I'm starting to consider that the rest of the household might not be so hip to that.

is it reasonable to consider dd (or some sort of windows program similar) every drive, compress it as far as possible/splitting into 4gb chunks, and writing to dvd ? seems frankly, like a nightmare.

there is unison and rsync.


Ford, the problem about IA64 is, that even the Intel C-Compiler isn't clever enough to utilize all its features.

Instead it can create real fucking fast amd64 executables ;-)

I thought we had an electronics room...
I've got a mini jack plug, as in the female side.
I've got a male jack that plugs into it.
I'm wiring together an extension cord out of bits in my pile of crap.

Anyway, the male side has two wires coming out of it. Each wire has

inside the insulation another insulated wire (which I assume is the hot

lead or whatever you kids call it nowadays) and another wire between
the inner-insulated wire and the outer insulation.
So there are 4 wires.

The female side has three contacts. I assume that on the male side,

the in-the-middle wires are the ground/return/whatever you call it
which can be wired together to the equivalent lead on the female side.

And the other two double insulated wires are
left and right and go to
one of the other two leads on the female side.
Now it's possible my female side is shorting somewhere, but for the

life of me I can't wire it so it works correctly.
Does anybody know of a good exploded picture on the web of this
scenario? I couldn't find any.

That is right, the wire that is all the way in the center is the signal lead, the wire that is outside that one is the shield. What you have got there is two small, shielded (probably crapily, but shielded) cables within one outer jacket. Since your plug probably is a TRS (Tip Ring Sleeve == Three Contacts), then the two shields probably go to sleeve on both ends, and one hot wire goes to tip, and the other goes to ring. Since it seems you are dealing with a molded plug, the only way to know which hot wire goes to tip and which to ring is to test it with an ohmmeter or continuity tester. But if it is a stereo audio connection, you might not care if the channels are reversed, it will work either way, the channels will just be switched around. So if that is how you wired it, and it didn't work.. then maybe your molded cable is just a piece of shit (most of them are) and broken inside. Which a multimeter can tell you.

that was the conclusion I came to as well.
then I found the cable I was tryin to make on ebay. for 80 cents. shipped.
From hong kong.

Got that? I can move a letter from ny to hawaii foe 45 cents. but for 80 I can move and BUY a cable from hong kong.
This is a very messed up world.

PanaSonic: in my house we keep everything on the server. All user accounts are authenticated against the server, and all home directories are stored on the server. On Linux it's obvious - just attach to NIS and mount /home from NFS. We also hooked up the Mac that way, but Apple makes it a little trickier; you have to use a program called NFS Manager to get the mount just right, and then set aside the "/Users" directory and replace it with a symlink to /home.

It works really well and no one ever has to think about backups. If a computer were to vaporize it would just be a matter of fixing it and then reinstalling the software. All user data is server-side, right down to the desktop layout.

The server itself is of course backed up on a regular basis.

true but I dont want to buy a case power supply and hard drives if I dont have to.
and the prebuilts I looked at dont seem to have the few things i want.

Ok, well in that case, at least get one of their package deals on a motherboard pre-populated with the correct CPU and memory. It saves the hassle of trying to match everything up.

Ford, be careful what you wish for. There are lots of boards that support 16 gigs with just 4 memory slots on midrange desktop chipsets. The problem is that in order to get 16 gigs with 4 slots you need 4x4 gig sticks which will probably cost around $2500 for the memory.

If you really, really think you want more than 8 gigs, then you have two options: (1) Buy a "Core i7" motherboard, which is outside of your specified price range; (2) Buy a Xeon motherboard of some kind, with at least 6-8 memory slots; or (3). 3 options. (3) Buy an AMD board, most likely a server-class board for Opteron chips.
