The I,K, and M root servers are outside the US and are controlled by entities which the US can't directly bully into doing their bidding.

11 Trillion Gallons of Water Needed To End California Drought

afidel Re: 11 Trillion Gallons of Water Needed to Water R (328 comments)

That's too high, most estimates are ~80-100 gallons per person per day, average houshold size is 2.6 so that puts you closer to 100,000 gallons per household per year. I also question how those estimates are so high, my family of 4 averages closer to 50 gallons per day at home based on our water bill and we don't do anything extreme, we take regular baths, wash our clothes by machine wash, run the dishwasher every other day on average, brush our teeth twice a day, etc. The only "conservation" effort we put into water is not watering our lawn, in fact I drilled out the restrictor in my shower head because I HATE low flow showers and I believe I've got an old school high GPF toilet since my house is from 1963 and most things have not been updated in it.

Is Enterprise IT More Difficult To Manage Now Than Ever?

afidel Re:Question doesn't match (241 comments)

I doubt it was new then, either. Businesses don't like to spend money, and IT gets classified as a cost center.

Then your IT department needs to become a business partner and enabler. That's the tact we've taken, the vast majority of our costs are in projects, and we let the business drive those with us helping to steer them, if someone complains about IT spending we ask them which of their projects they want us to defund. We recently completed an acquisition equal to about 40% of the size of the company, without adding any significant headcount, all because our IT systems have gotten to the point where the business can absorb that many extra units without adding significantly to their workload and the work around the new assets is mostly loading the data into the system which we do for them. Since we've taken this approach our budget issues have become almost non-existent and our interaction with the business have become much less adversarial.

Computer Error Grounds Flights In the UK

afidel Re:Power failure to the computer (68 comments)

So stupid, it's not hard to achieve damn near 100% uptime on power, get feeds from two substations A and B, put each one through two UPS's and use two different sets of generators with different fuel sources as backup so you have A, A', B, and B', use a transfer switch to feed your equipment's A side supply from A with A' in reserve, and the B side supply from B' and have B in reserve (that way one of your power sources stays up without a transfer switchover even if you have a fuel problem). If you want to further reduce the chances of an outage at the cost of some increased complexity use different UPS vendors and different transfer switch vendors so you don't have a possible common design flaw in both paths. The whole setup would probably cost as much as shutting down Heathrow for around 10 minutes. I've got this setup minus the redundant generators and I'm just running a midsized enterprise, not a freaking critical piece of national (and international) infrastructure.

Liquid Cooling On the Rise As Data Centers Crunch Bigger Data

afidel Re:The trend in servers seems to be "lousy cooling (25 comments)

but replacement costs are still lower that energy costs long term.

I'm not buying it, my VMWare hosts are pretty large boxes and they've used 630kWhrs since June when they were installed, that comes out to $128/year or so, and that's for primary usage, DX CRAC units have a PUE of ~1.28 which means it costs around $36/year to cool. Even with really cheap servers you'd have to have a LOT of them and have very little effect on AFR to justify it. I'm sure at some scale it makes sense or everyone wouldn't be researching it so hard and doing so many pilot datacenters, but if you don't have thousands and thousands of identical servers (99.999+% of installations) it's just not worth it.

US Navy Authorizes Use of Laser In Combat

afidel Re:End of flight as we know it (225 comments)

Huh? There's no way a missile can outmaneuver the optical targeting system on these things, the biggest threat will be surface skimming that will reduce the targeting systems reaction time, but the newest class of ships have pretty good synthetic aperture radar and the computer aided target discrimination is getting better all the time.

US Navy Authorizes Use of Laser In Combat

afidel Re:End of flight as we know it (225 comments)

Not perfectly, and the energy absorbed from a 30kw laser will quickly darken the surface accelerating the rate of energy absorption. Here's a video of a 500W laser cutting into a mirrored surface.

Utilities Face Billions In Losses From Distributed Renewables

afidel Re:Reduced revenues != lost profit (280 comments)

One can either massively over produce in summer or rely on grid power in the winter. If one is relying on winter grid power then the equipment generating that power will only be used a fraction of the year.
My average power draw during the summer is ~4x my winter draw since I use natural gas heat but air conditioning, and I'm fairly typical. So you design your solar system to produce ~75% of summer demand and your grid demand remains relatively constant yet significantly lower than today which should actually reduce the utilities costs significantly since they will need fewer plants and less grid infrastructure and fewer grid upgrades.

Utilities Face Billions In Losses From Distributed Renewables

afidel Re: Reduced revenues != lost profit (280 comments)

Do you watch use your computer after dark? There is 400 watts.
LOL, on slashdot that's funny. My VMWare hosts which are dual 10 core Xeon's with 384GB of ram, multiple network cards and fiber channel HBA's peak just over 300W:
Last Week-
average 183 W | 625 BTU/hr
peak 301 W | 1027 BTU/hr

Unless you're running dual GPU with a 60" display there's no way you're using 400W.

Utilities Face Billions In Losses From Distributed Renewables

afidel Re:Reduced revenues != lost profit (280 comments)

The problem is off-grid systems are a LOT more than 2x wholesale grid prices, and storage tech isn't moving anywhere near the pace of panel production (it turns out storing electricity chemically in an efficient and reversible process is really, really tough to do economically)

Ask Slashdot: Are Any Certifications Worth Going For?

afidel Re:practical-based certs hold their value (317 comments)

CCIE is God level

Not really, as of 3/2013 there were 38,005 worldwide, a little more than one in 200,000 people worldwide holds the cert. That IS roughly the same density as neurosurgeons though, and those guys do tend to think they're gods too.

Ask Slashdot: Are Any Certifications Worth Going For?

afidel Re: There is a reason for this! (317 comments)

You're misreading, the QuantumFlow Processor IS the ASIC
Further, each PPE can access hardware feature acceleration of network address and prefix lookups, hash lookups, WRED, Traffic Policers, range lookups, and TCAM for advanced classification and access-control-list (ACL) acceleration as it processes packets

If you turn off dCEF and force all packets through the RP CPU you'd quickly bring an ASR to it's knees. By comparison the Cisco 7200 did everything in CPU, but it had much lower bounds to its capabilities.

Samsung SSD 850 EVO 32-Layer 3D V-NAND-Based SSD Tested

afidel Re:SDxC is cheap up to 64GB, expensive above (127 comments)

Google SDXC nGB and you'll find plenty of ads for cheap memory, the PNY one seems to be the only reasonable one at 256GB, but there are quite a few of the usual second tier players at 128GB.

Samsung SSD 850 EVO 32-Layer 3D V-NAND-Based SSD Tested

afidel Re:Very cool. (127 comments)

And since SDXC cards are available at ~ $.40/GB (up to 256GB) addon storage is competitive with 2.5" SSD's in price if not performance. It would be nice if the internal SSD was about 4x that size though so you could have more programs than the base installed, but that would add ~$40 to the price which would make it too expensive to compete with Chromebooks.

Consumer-Grade SSDs Survive Two Petabytes of Writes

afidel Re:HDD endurance? (125 comments)

Not really, for streaming writes a HDD is only about 1/3rd the speed of these drives (WD Caviar Black 1TB, 150MB/s sustained streaming write vs Intel 335 at 450MB/s streaming writes).

You're Doing It All Wrong: Solar Panels Should Face West, Not South

afidel Re:But that isn't possible (327 comments)

At least here in Ohio they'd get their transmission charge, which is roughly half of the cost of residential power, not bad for doing nothing but line maintenance =)

You're Doing It All Wrong: Solar Panels Should Face West, Not South

afidel Re:But that isn't possible (327 comments)

Residential installations also require fewer transmission system upgrades which can be a significant factor in overall costs. It's one of the reasons my mind boggles when utilities complain about net metering, the power is going to be produced and consumed on the local portion of the grid which is unlikely to require any new capital improvements to accommodate the solar generation until solar reaches stupid high concentrations whereas adding the same amount of total capacity at a remote location is going to cost them megabucks to build new transmission and distribution capacity.

You're Doing It All Wrong: Solar Panels Should Face West, Not South

afidel Re:screw demand (327 comments)

If you're a utility you have your panels set up so that they rotate to face the sun

Nope, it's more economical to just stagger your layout if you want multiple inclinations, the cells are less expensive than installation in the western world, let alone expensive helio-tracking systems that are capital and maintenance intensive. The only solar tracking systems done at scale that I'm aware of are solar thermal plants, and even there the newer plants are single axis.

The article mentions this being a break from Dell's longtime Intel exclusive partnership. Is the love afair over, is Dell throwing Intel a bone to help them with their antitrust lawsuit and has no real plans to push the Opteron servers, or has customer demand finally forced their hand?"
