How Big Should My Swap Partition Be? 900

For the last 10 years, I have been asking people more knowledgeable than I, "How big should my swap be?" and the answer has always been "Just set it to twice your RAM and forget about it." In the old days, it wasn't much to think about — 128 megs of RAM means 256 megs of swap. Now that I have 4 gigs of RAM in my laptop, I find myself wondering, "Is 8 gigs of swap really necessary?" How much swap does the average desktop user really need? Does the whole "twice your RAM" rule still apply? If so, for how much longer will it likely apply? Or will it always apply? Or have I been consistently misinformed over the last 10 years?

Virginia High Court Wrong About IP Addresses 174

Frequent Slashdot contributor Bennett Haselton writes "The Virginia Supreme Court has ruled that the state's anti-spam law, which prohibits the sending of bulk e-mail using falsified or forged headers, violates the First Amendment because it also applies to non-commercial political or religious speech. I agree that an anti-spam law should not outlaw anonymous non-commercial speech. But the decision contains statements about IP addresses, domain names, and anonymity that are rather basically wrong, and which may enable the state to win on appeal. The two basic errors are: concluding that anonymous speech on the Internet requires forged headers or other falsified information (and therefore that a ban on forged headers is an unconstitutional ban on anonymous speech), and assuming that use of forged headers actually does conceal the IP address that the message was sent from, which it does not."
