I have been wondering; is it electrically and thermally possible to put eight Intel Xeon 7500 Series processors and a terabyte of RAM into a single 2U server? I mean a single system server, whether it has eight sockets on a singe baseboard or it consists of two quad-socket boards glued together. Amax's ServMax X1401 has half of that (four Nehalems and 512GB of RAM) in half the space, and the Cray CX1000-SC achieves eight Intel Xeon 7500 Series processors and a terabyte of RAM in 3U of rackspace but lacks redundant PSUs and multiple PCIe slots...

If I installed a Gulftown Xeon processor on a (LGA 1366, X58) desktop motherboard, can I also install non-ECC, unbuffered ("regular") memory modules on the motherboard? The motherboard is known to support the processor.
More generally, given a motherboard and a supported processor, how do I determine what kind of memory to install? I am not asking about memory type, clock, size, and the number and placement of modules, but the ECC-, buffered-, and registered-ness of the memory.
Thanks for the answer. 118.96.155.129 ( talk) 01:01, 4 December 2010 (UTC)
Is there a way in HTML to embed an object, like a flash movie, but instead of a height and width value in the embed tag, have them both be variables and use some sort of input (on the page or otherwise) to change these variables "live" on the page (without needing to refresh)?

(edit) I'll play around with this. The flash video in question DOES allow different sizes and seems to work with various sizes, i just dont know how it would respond to being told to change its size on the fly as opposed to editing the tag and reloading the page. :o 137.81.118.126 ( talk) 01:44, 4 December 2010 (UTC)
I tried this with my video file as well, and also got the desired result, thanks! 137.81.118.126 ( talk) 01:54, 4 December 2010 (UTC)
Let us suppose a hypothetical (yet possible) scenario where the United States passes a bill that destroys net neutrality and allows ISP's to selective throttle internet traffic or implement multi-tiered service. While it is likely that certain sites unable to pay a premium will be slower than before, suppose that the ISP really dislikes a specific site, say WikiLeaks for example, are they able to completely block the site or slow the traffic to a point where it takes like an hour just to load one page?
If so, how does this compare to the "Great Firewall" internet censorship in China? In China, you are still able to access blocked sites using proxies such as Tor, but can you do the same if ISPs in America decide to censor certain websites? Are there any technical solutions around this in the US?

I am looking more towards the technical implications of both scenarios. What is the relative difficulty between the two systems in accessing restricted websites? Acceptable ( talk) 04:24, 4 December 2010 (UTC)
Both [1] and [2] seem to be down for me. [3] and [4] says "it's just me." What's wrong here? —Preceding unsigned comment added by 212.169.185.150 ( talk) 17:57, 4 December 2010 (UTC)
We need to define "down." At present, (20:19, 4 December 2010 (UTC)), the Wikileaks server is active, the domain name has been de-activated, and the PayPal account has been de-activated. Nimur ( talk) 20:19, 4 December 2010 (UTC)
Hi, I have a quick question.
Suppose I have some nice code like so:
But what if foobar is a method within class thing... can I say
Basically, I need a method within a class where two object references point one to the object passed and the other to the object that called the method, or vice versa according to a random() coin toss.
Thanks!

Hmm, let me see if I can rephrase the problem.
There is a class called nCraft. It has the member data nCraft.health and nCraft.fire and a method nCraft.attack(nCraft victim) So for example, I could say alice.attack(bob) and in the method, based on a random() outcome winner = bob and loser = alice or vice versa and health is changed accordingly.
Duomillia ( talk) 00:25, 5 December 2010 (UTC)
public void foobar(Thing t) {
Thing winner, loser;
if(Math.random()) {
winner = this;
loser = t;
} else {
winner = t;
loser = this;
}
}
Also, if other methods depended on who won and who lost, it'd be better to make winner and loser be instance variables, or better yet, have the method return a Thing[]. And, something neat I learned just yesterday, (the super long question about jdialogs) are some code tags. Use <syntaxhighlight lang="java"> and </syntaxhighlight> around your code.

Thanks! That's exactly what I needed! All I need it for is something like this:
winner.gold += looser.gold;
looser.gold = 0;
But I wasn't sure if I could use 'this' all by it self as a reference to self. Well, it looks like I can. Thanks! Duomillia ( talk) 04:49, 5 December 2010 (UTC)
