No. Stability control works to reduce yaw under hard cornering or emergency maneuvers, so that the tail of the car doesn't slide. Traction control, on the other hand, uses the ABS system and torque vectoring (if the car is so equipped) to reduce wheelspin on a wheel that is slipping, and increase the traction of the opposite wheel that has traction. It's more to reduce wheelspin while driving over loose road surfaces or wet/snow conditions.

Bleach doesn't soften the tires, it's just more slippery than water, so people with underpowered cars use it to do burnouts. At a drag strip, they use water, because normal people that understand how to drag race wouldn't let bleach touch the paint on their vehicles. The idea is to heat up the tires (by doing a burnout) and thus, soften them to get better traction.

That said, you NEVER do this with street tires or drag radials, only slicks.

Comment Re: Burnouts are illegal. (Score 2) 290

The key you're referencing is for the Boss 302, which remaps the engine tuning to provide additional power and less streetability.

I'm definitely of the camp that no auto manufacturer is going to put a burnout button on their vehicle, both because of legal reasons, and because burnouts prematurely wear many components, including brake pads, tires, transmission, axles, etc. The maintenance/warranty issues would be absurd. Imagine you do a burnout with Ford's burnout button, dump the clutch, and it shatters, tearing a hole in the transmission bellhousing, opening up the hood, and puncturing a tire. Then imagine a smoking hot piece of clutch disc hits someone and injures them. Option 1 is that Ford says - "Well, you took the risk using that feature, so we're not covering it." Option 2 is is that the person hit with the clutch disc sues the driver, Ford, the dealership, the engineer that designed the clutch, the engineer that designed the burnout system, their insurance companies, et al, and comes away with a six-figure settlement.

When I worked for Lockheed Martin, emphasis was placed upon degrees and formal education, and though I have a BS in Business Administration, I have an ME in Systems Engineering, with a concentration in Space Systems.

Now that I work for another defense subcontractor, more emphasis is placed upon technical certifications, so I've run through the CompTIA gamut, got my Certified Information Systems Security Professional (CISSP) cert, and have about another half dozen technical and security management certs planned out.

Right, but they're not front-line warfighting systems, they're small, standalone systems that don't connect to any other DoD systems, otherwise, they'd never get an accreditation, and neither would their associated systems.

I've seen random little one-off systems that use a one-way tactical data link to provide simulations for other systems, but they're only accepted because there's no duplex communication possible, it's one-way only.

Comment Re:Licencing... (Score 1) 229

Speaking from someone who had to get around licensing to use FOSS components, it's a tough line, and one that has to be carefully navigated. We had to submit any FOSS packages that weren't delivered explicitly with the install media to a legal review board, and it would take weeks to get an answer back. Further, we needed to submit each revision (1.2 to 1.3, not 1.2.1 to 1.2.2) to the board for approval, just in case the license had changed.

Comment Re:235 server racks in one ship? (Score 1) 229

Besides just the core operating environment, there are literally dozens of other systems, from Hull-Mechanical-Electrical (HME) to unclassified NMCI email terminals, and everything in between. The core combat system will run off about three dozen racks, while the rest are random systems scattered throughout the ship, and a 'rack' might mean a small switch cabinet in a closet somewhere.

That is incorrect. Current DIACAP/DoD guidelines require that end-of-life operating systems be retired and replaced with newer versions. Sure, there are some XP machines floating around on legacy systems where the cost of replacement or upgrade exceeds the value of the information and the information system, but those are not afloat, warfighting systems.

Ohio-class subs are missile platforms, capable of launching a couple dozen ICBMs with MIRVs, for nuclear deterrence. The Seawolf-class was designed for attack, same as the Virginia-class. They discontinued the Seawolf production line after the USS Jimmy Carter was built, because it was built to Cold War specifications, and was an outdated design. The Virginia and her successors incorporate Seawolf design features at a much lower cost and with much more capability. They'll be replacing the Los Angeles-class attack subs for the next several decades.

That said, the Ohio-class' last boat came online in 1997, and will eventually need to be replaced. The oldest, the Ohio, Michigan, Florida, and Georgia, were converted to Guided Missile subs, and now only embark the Tomahawk missile. The oldest of those boats came online in 1984. They'll have a long life, but they'll need to be replaced, starting in about 2029.

Agreed. I previously worked on the combat systems for the Ticos, Burkes, and the LM variant of the LCS, and these are completely superfluous, only being built to appease the Marine Corps brass. The Navy didn't want them, but the Corps did, since there's no dedicated shore bombardment platform in the US arsenal, other than utilizing attack aircraft and Tomahawk missiles. Some senators and congressmen got behind the program, as it would funnel pork dollars to their districts, and it was set into motion. It was then cut back significantly, because it can't do the number one role that Navy DDGs and CGs are tasked with, AAW, nor can it do BMD. Hence, the Navy is buying a dozen or more Flight IIA and III Arleigh Burkes.

Well, it's more relative to using electronic countermeasures to saturate the radar, then deploying a salvo of weapons, perhaps 10, or more, to try to confuse and overwhelm the combat system and the personnel staffing the combat system. Course, all Destroyers and Cruisers, as well as all other major combatants, have Cooperative Engagement Capability, and can communicate with each other, share radar tracks, launch weapons from another ship's VLS system, etc. Just because you've tried to blind one combatant, doesn't mean you can blind them all.
