I run backuppc on a free Pentium III running linux. It backs up itself (tar), 2 window machines (SMB), a macbook (ssh and tar), and my website (ssh and tar). It is fully automatic, and does full, differential, and incremental backups. My wife can browse backups and restore individual files herself. If a file appears in more than one backup, even if from different machines, a single copy is stored. I now have 20 full backups, and 93 incrementals using just 36 GB. For our document folders, we do incrementals twice a day.

I make an occasional offsite backup by imaging the disk to another one (craigslist!) giving it to a family member for storage.

CONS: doesn't know about Mac resource forks, windows multiple data streams, ntfs permissions, ...
Configuration required condsiderable tinkering. A full restore would require reinstalling the operating system, then putting user files in their proper places.

I use BITS to transfer large files across flaky wireless networks. The way I use it, the sending end can be any http server; only the receiving end needs to run Windows and have the BITS service running. You can just use the clumsy command line bitsadmin utility to queue and manage requests. If you want transfers to continue while people log in and out of the windows machine, you must submit the job to run in the system account. The Sharpbits program mentioned about doesn't do that last I looked. You can submit a job under any account, then use the bitsadmin "/takecontrol" command to push it into the System account.

Could we get a source other than the New York Post please? The paper called itself "New York's daily picture newspaper". Since Murdoch took over, it has only gotten worse. It makes me embarrassed to live in New York City.

From Wikipedia:
"In 1980, the Columbia Journalism Review asserted that "the New York Post is no longer merely a journalistic problem. It is a social problem - a force for evil."

The New York Post is for gossip, clever headlines, and sports. But not for journalism. It's like slashdot, but dumb.

I don't belong to Anonymous, but if things get any worse I might want to join. How do I get in?

I don't think most people even understand what mathematics is, so I recommend reading something about the history of mathematics. The World of Mathematics edited by James R. Newman has a very good collection of essays, fragments of ancient mathematics, and even short books. It is four volumes, but I eagerly read all of it in High School. The parts I remember clearly are: mathematics in antiquity, Gauss, the 19th century number theorists, an essay by Poincare about creativity, and lots of amusing applications.

A Source Book in Mathematics edited by David Eugene Smith has famous papers, from the ancient world to the 20th century. Some are advanced, but it's ok to look at stuff you don't understand.

My various print dictionaries do not have any words with the prefix syncro- ,
nor anything related starting with cron-. Think chronology, chronograph, etc.
