I use 'sfdisk --dump' for MBR partition tables. Maybe gparted has a similar option?

I had a question you may be able to help with: if I wanted to clone a drive with, say three partitions, using dd (let's say the combined partitions are using 25% of the total drive space, hence the desire to back up on a partition-by-partition basis - to save time) could I use a similar methodology to back up the gpt boot record? Obviously instead of nuking, I'd be saving the relevant sectors and then restoring them into the same place when needed Very helpful thanks.

That one runs even cooler (65W avg. @ 56 dB). But even with a full-sized 1U it's difficult to get much storage into them, which was a main criteria for this box.

What you really want to try and do is get a bunch of 1U machines, and quieten them down enough to home-host ( can be done, depends a lot on what cpu performance you need ) - KB a 4U box is just a normal desktop tower turned on its side.

It looks like spam to me, especially how I get bunch of them. The mailserver they use is blacklisted in some lists as well.

One was to my real address. Two were to non existing addresses (random ? numbers) on my private domain, that I receive anyway, mine being the fall-back address for my own domain. I am not a professional and I do not know where they found my address. The two forged addresses on my domain clearly indicate voluntary spamming. Looking on Google (where I found this blog entry), there seems to be two different CISSE. A 12th CISSE was held in June 2008 at the U of Texas, Dallas. The spam is for a 4th (virtual) CISSE where CISSE has a different meaning. This 4th CISSE or CISSE 2008 is mentioned on a few sites of other universities. May be serious. Their way to spam people is not. Got three such mails sent at 14:13:43 -0700. One was to my real address.

I don't think that is an accurate description. I've spoken with folks from Burlington, and they are doing well. These projects take many years to break even and BT is near that. As for ECFibernet, I'm fairly certain the plan was always to get funding via a capital lease - this is what Nulty knows best and how he intended to approach. Getting some money from Vermont was something they wanted just to show support from the state to get a better interest rate from private investors. The investors will be repaid with revenues from subscribers - so the network is self-funded in the long term. BT having revenue shortfalls? I don’t think that is an accurate description.
