Not even several percent - it's so infrequent as to be almost unmeasurable. The other two D-D reactions you mentioned are split almost perfectly 50-50 at energy levels between 400KeV and 1MeV or so. Below that, the D + D -> He3 + n is somewhat more common.
Hi,
2D -> He-4 + E is not correct. There are actually two different reactions that may occur, and neither is the one you have stated. These are:
D + D -> p + t + 4.1MeV
D + D -> n + h + 3.2MeV
Where the first byproduct is a proton, a tritium nuclei, and 4.1MeV of energy, and the second is a neutron, a Helium-3 nuclei, and 3.2MeV energy.
Both Tritium and Helium-3 are good fusion fuels in their own right, making the D-D reaction ever more valuable, as it's products may fuel subsequent reactions.
Also note that D-D fusion is the second easiest reaction to produce, after D-T.

You don't need to keep track of who voted, only of who _registered_ to vote.
When someone registers, they get a one-time name/password. Then after they vote, they can't use it anymore.
So you just need to know enough not to assign someone an account multiple times.
Here's an easy solution: Build the firewalling stuff into your kernel (or as modules) and just deny all incoming traffic on those ports that is not from localhost.
Of course, it'd be just as easy to run the other box as NAT. And as several others have mentioned, a 486/66 can route for a T1 with no problem. Cable shouldn't give it a problem.
I don't know about the rest of you, but I'd rather have some idea of specific things to watch out for on my networks rather than having no idea. I prefer a product that's had a few holes fixed rather than one that has who knows what...
I dunno about you, but when I first started getting into computers it was in a large part becuase they were so intuitive... Not that everything was easy, but it made good sense. Oh, and AND/OR does _not_ mean the opposite thing on a computer as in real life... At least not any way that I can think of to look at it.
I'm in tenth grade, and I just got a laptop for school about a month ago... I now look back on the time before like the dark ages. I take notes on it, type my assignments (having almost illegible handwriting), and just about everything else too. It's bascially become a necessity for me. It also gives me plenty of stuff to do when I'm bored...
Because of the fact that the vast majority of people are either incapable or unwilling to understand the issues, that means it is up to those who do understand to guide the decisions in such a way to benifit _all_ the users, and protect them from laws that endanger them. Sure, alot of people believe that everyone should be responsible for caring about this stuff themselves (I'm often one of them), but can you realistically expect the average person who only cares that the darn thing works, and screw understanding why, to be competent enough on the issues to realize what legislation is helpful and what is harmful? The average person doesn't care until they get a credit card bill of $5,000 they didn't spend, and by then it's often too late.
I listen to music whenever I do something that requires concentration; it helps me slip into "that mood" -- you know, where I forget to eat and sleep becuase I am so focused on a problem...
Anyways, my current list includes: Nine Inch Nails Tool Prodigy (on occasion) Pink Floyd The Sisters of Mercy The Cure Dead Can Dance
It would probably be a good idea to give something like this support for current protocols (ICQ, AIM...) One of the reasons ICQ is so popular is becuase it has such a huge user base. People use ICQ because so many othet people do also. By giving it support for a couple protocols, you can tell the user "Hey, look, you can communicate with people on all these services using just one program." And then by giving the program a preference of the new protocol over the old, you would have a nice, painless changeover to the newer (and hopefully better) protocol.

Very simply, 1 (along with -1) is neither prime nor composite.
+-1 is a unit.

Hey, I'm a good bit older than 2, and my favorite question is still "Why?"
Anyone have a pole pig they can try that voodoo 3 stunt with? Now THAT will make a spark!

I believe the poster was just refering to the final effects, and how they were alike, and not trying to attribute anything to the script kiddies.

Actually, it would probably be better just to remove the specific sections, and insert something like
[ this section has been removed for legal reasons. It is available in (section whatever) from (some document), which is available (some place) ]
Of course, the best solution is to leave them all alone...

Then that's one racist antisemitic crack-dealing pimp who still has some hope.
they're not bugs, they're just undocumented features...

Notice that they place 'most common' on the rightmost of the graph, instead of in the center of the curve.
