South Korean Power Plants To Conduct Cyber-Attack Drills Following Hack

confused one Re:Huh? (23 comments)

It's pretty common for there to be a data link from the control system to the outside world. This is to provide feedback and monitoring capability -- for load balancing, security, and so the managers have access to information about the state of the machine(s). If they're smart, this data stream is one way only, with an intermediary firewall / server controlling access. If they're really smart, the cable only has the Tx pair connected.

Hackers' Shutdown of 'The Interview' Confirms Coding Is a Superpower

confused one what crap (220 comments)

I don't believe the premise at all...

However, if coding is a super power; then, by my greying beard, I am a GOD!

Geoengineered Climate Cooling With Microbubbles

confused one Re:Cheap nanobubbles (113 comments)

Not just oxygen... We can accelerate absorption of CO2, SO2, and all those other nasty, evil gases in the atmosphere. We've found a solution! What could possibly go wrong?

Vinyl Record Pressing Plants Struggle To Keep Up With Demand

confused one Re:Not really missing vinyl (433 comments)

No. The "warmth" he's referring to had more to do with the way a needle tracked the groove, the way a tube amp interacts with the speakers (damping and harmonics), and the way a guitar amp that uses tubes rolls off instead of clipping. All is not a bed of roses in analog land... Us old guys grew up with this stuff and remember it as "the way music is supposed to sound". Digital's not the panacea it's made out to be either... overcompression, lossy recordings and poor reproduction from most modern releases leaves something to be desired. You young guys have been trained to ignore all the high frequency digital artifacts that bug the crap out of some of us.

Man Caught Trying To Sell Plans For New Aircraft Carrier

confused one Re:Entrapment is lazy policing (388 comments)

With the right drawings you would know exactly where to hit the ship with a missile to do maximum harm. Use your imagination.

Man Caught Trying To Sell Plans For New Aircraft Carrier

confused one Re:What in the hell was he thinking? (388 comments)

Well, that depends. If the "drawing" is a full 3D assembly, a 3D model of the ship... You can do some amazing things in SolidWorks and Inventor these days.

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

confused one Re:obviously they should track the sun (327 comments)

I should have made something more clear: the insurance and liability risk is a key factor... If I sell an item that breaks and damages a house in a storm, and the insurance refuses to cover the item and the house... Especially if the house would have normally survived the storm without my system being installed... Then I'm looking at a lawsuit (from either the homeowner, the insurer, or a government agency). So, basically, it's not at all in my best interest, nor is it ethical, to sell you something that's not going to meet the minimum wind rating -- even if that's "Hurricane Rated Z3.4 and 80 mph winds". I just won't put the product on the market knowing I'm going to eventually be sued.

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

confused one Re:obviously they should track the sun (327 comments)

One of the problems is it has to be rated for high winds; or, you're not going to be able to insure your house if it's mounted on the roof. OK, you might be able to insure it but they might void the coverage if you get wind damage that can be attributed to the panels. Accuracy really only needs to be a +/- a couple of degrees for PV. Hell, most people mount them flat to the roof, which is not pitched anywhere near ideal. some of the larger synchronous motors probably do have enough torque to push over a single panel; and, you can build a cam driven system that tilts the panels in a cyclic fashion. Problem is, if the power ever goes out it's going to be hell to reset all of them. Theoretically, you could use a system that relies on the Sun to heat and expand a liquid, pushing the panels from a "morning" orientation to an "afternoon" orientation. In the end... You're still going to pay more than $200 for a structure with "motor" that's strong enough to do the job and well built enough to survive for 10 years on a rooftop. You could probably make it for a couple hundred dollars; but, you'll never buy it for cost -- you'll end up paying double that (at least) after manufacturer overhead (design and support) is rolled into the cost, and the distributor(s) and installer(s) mark up the price.

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

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

There's another reason besides aesthetics... the mounting is simpler, cheaper, and stronger if the panel is mounted parallel and close to the roof surface.

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

confused one Re:obviously they should track the sun (327 comments)

Just a guess (from an engineer, so it's a sophisticated guess)... Might be $200 per panel because the motor has to be big enough to move the panel in prevailing winds; and, the structure has to be strong enough to keep the panel from being ripped off the roof during a storm. Again, just guessing.

Ask Slashdot: Making a 'Wife Friendly' Gaming PC?

confused one Re:quiet case water cooling (720 comments)

I spoke too soon. The passive version of the Zalman Reserator is no longer available... There are other options, like Alphacool passive radiators.

confused one quiet case water cooling (720 comments)

move your machine into a nice quiet understated case like the Fractal Design R4. Use a single 140mm or larger low speed fan just to move the air through the case. Then water cool it and use a large passive cooler... Something like a Zalman Reserator. Once done, the only noise will be the pump(s) and the single fan.

I prefer my turkey ...

confused one Re:Manifold? (189 comments)

What I didn't say, but was intending to imply above, is that was for older engines. My new Ford 4 cyl with the polymer intake manifold... not so much. Modern fuel injection manifolds are dry, and as cold as they can keep them. Plenty of room on the exhaust manifold shield though.
