The most likely cause of the confusion is that you don't have proper rDNS setup for your domain. Get your ISP to point the rDNS for your IP to your domain and you likely won't end up on an RBL again (no promises obviously).
Two hour? Last time AT&T screwed up our DS3 it took over 3 *days* for them to fix it. Luckily we had a time warner business class line that we were using to provide guest wireless and it was enough to keep everyone at HQ working and mail routed through our DR site. Unfortunately it didn't have enough upload to keep all our remote offices connected into our Citrix environment so the field basically did whatever they could do locally for that time. Since then we have brought in TW to run a fiber connection into the building and upped our connection to 10/10 and it can be turned up to 1000/1000 with 24 hour notice so if there's a next time we can provide full services with just a DNS change.
Globalhawk's very cool but I doubt it could fly below cloud deck during a noreaster on the Bearing Sea as an example of what I'm talking about. In fact I doubt any fixed wing aircraft could do it.
Actually there's only about 75kg of Tritium in the current stockpiles according to one report I ran across while researching some other posts so the current stockpile probably are NOT sufficient to meet possible demand even if we wait till 90+% have decayed. On the other hand we could generate Tritium just to produce He-3 for peaceful purposes but then the cost would apparently be closer to the $1,5000/L quoted in the article.
By naturally occurring Tritium I mean from sources like cosmic bombardment and the decay chain of other radioactive materials. Since the He-3 itself doesn't decay that means it should accumulate over geographic time and some percentage of any large concentrations of He will obviously contain some non-trivial amount of He-3. My question was around how feasible it would be to extract whatever amount is present in the Billions of liters of He we have stockpiled.
Yes but I have to assume at least some of the trapped helium in those reserves was created from the decay of naturally occurring Tritium. Wikipedia gives its abundance as 0.000137% of He which means unless it has some property that makes it easy to separate it would probably be extremely energy intensive to do like say cooling it to below 4K where the Helium-3 remains gaseous but the H-4 becomes liquid.
I doubt the drones will even be able to fly in the kind of conditions that cause most coastguard calls. Now for analyzing the video provided from the FLIR pod on the rescue copter, that's probably a great helper for the crew.
So is this one of the impacts of The Helium Privatization Act of 1996 or is separating the Helium-3 from the more common isotopes too energy intensive to have made the Bush Dome Reservoir a viable source?
It was pretty widely reported that the government used a threat of not leasing time on EC2 to get Amazon to quit accepting donations, not sure what they did to paypal but I'm sure it was something like threatening to regulate them like a bank.
Was this for workstation or server use? If server and you were actually putting a decent workload on it then you should have bought the x25e instead of the x25m, mlc flash such for high write workloads, especially random writes.
Huh? I've had 10GbE in the core as long as I've been at my current employer (coming up on 5 years) and I'm seriously looking at it for all ports when my older 6509 core goes EOL. Just because cheap closet switches don't have 10Gb yet doesn't mean people aren't using it. Oh and it's coming down in price all the time, Linksys XSM7224S is a 24 port 10GbE switch with 4 uplinks for $8,700.
I do have more cabling but power draw's actually lower due to early FCoE adapters being complete power hogs. Rack space isn't a consideration for either my primary datacenter or my colo space since power density means I can't fill racks with servers anyways. Oh and at least for my applications storage bandwidth is much more important than IP bandwidth so I actually have equivalent bandwidth.
FC is so routable, there have been FC directors with routing capabilities pretty much since there have been FC directors. That said routed FC is kind of a hack but since lossless iSCSI requires DCB which also isn't really routable to get the same reliability you end up with the same limitations with a much higher complexity and CPU cost.
Actually FC has an inherent disadvantage and that is they ship about 5% of the ports per year that Ethernet does and so all their R&D has to be spread over 1/20th the ports. The vendors all realized this about 5 years ago and so they started on FCoE to spread their R&D budget over the much larger Ethernet ecosystem. I believe 16Gb FC will be the last standalone standard and that after that they will piggyback on Ethernet for 40Gbps and 100Gbps speeds. Speaking to industry insiders at Storage Networking World it's obvious that the days are numbered for standalone FC.
As to your claims that 10Gb FCoE is slower than 8Gb FC for throughput that's rubbish as the framing overhead for FCoE is nowhere near 20% and they are both lossless protocols, for latency it may or may not be true depending on implementation.
When Brocade introduced their FCoE switch I could pick up two 40 port 8Gbps FC switches and a pair of 48 port GigE switches with 10Gb uplinks for what they were charging for 24 ports of FCoE with 4x FC connections. So instead of going with the switch that probably cost them no more to manufacture I bought a pair of 5100's and bought a pair of stacking HP GbE switches and so had complete redundancy for about the same cost as one FCoE switch.

And then you get the aholes live VZW who ignore TTL and cache records for upwards of 72 hours =(

Obviously it accumulates in certain places since up to 7% of the Texas natural gas stream can be He.

Not sure about that as noscript is a bit draconian, but Chrome 9 and 10 with adblock are both faster than FF 4b10 with adblock.

Decreased complexity? I find iSCSI to be WAY more complex, especially if I have to go into yet another interface to configure the HBA.
sfp+ direct attach for top of rack, cables cost from $30-120 depending on the length you need.
iSCSI HBA's at 10Gb cost about the same as FCoE CNA's so where's the advantage?
Hehehe, FC is ~$1,000 per port for both the switch and the HBA and QLogic alone shipped 1M ports last year.

You think the astronauts don't use diapers today? Oh and space food is pretty much baby food as well.
You'd still want to check the threads before attaching the cap just to make sure and checking's a lot easier when they are white =)
Kind of like the engine room in Event Horizon =)
