Yellowstone Supervolcano Even Bigger Than We Realized 152

The Washington Post reports that the "supervolcano" beneath Yellowstone National Park (which, thankfully, did not kill us all in 2004, or in 2008 ) may be more dangerous when it does erupt than anyone realized until recently. Scientists have today published a paper documenting their discovery of an even larger, deeper pool of magma below the already huge reservoir near the surface. From the article: On Thursday, a team from the University of Utah published a study, in the journal Science, that for the first time offers a complete diagram of the plumbing of the Yellowstone volcanic system. The new report fills in a missing link of the system. It describes a large reservoir of hot rock, mostly solid but with some melted rock in the mix, that lies beneath a shallow, already-documented magma chamber. The newly discovered reservoir is 4.5 times larger than the chamber above it. There's enough magma there to fill the Grand Canyon. The reservoir is on top of a long plume of magma that emerges from deep within the Earth's mantle. ... “This is like a giant conduit. It starts down at 1,000 kilometers. It's a pipe that starts down in the Earth," said Robert Smith, emeritus professor of geophysics at the University of Utah and a co-author of the new paper. ... The next major, calderic eruption could be within the boundaries of the park, northeast of the old caldera. “If you have this crustal magma system that is beneath the pre-Cambrian rocks, eventually if you get enough fluid in that system, enough magma, you can create another caldera, another set of giant explosions," Smith said. "There’s no reason to think it couldn’t continue that same process and repeat that process to the northeast.”

There will be a market for vehicles with tunable performance characteristics. It may be a small market but it will exist, even if it's limited to track-only vehicles like Atoms. And, frankly, if you're modding your vehicle for performance to the point where you need to tweak valve timing yourself, you should be using that car on a track anyway.

Came here to say this. This has nothing to do with replacing your spark plugs or ball joints. This is about modding your ECU. That said, I think that if a manufacturer ships an ECU that can be modded to such a degree that it causes the brakes to fail, the manufacturer bears a lot of that fault. However, in general, cars aren't cell phones or PCs. It's no big deal if you load up Cyanogenmod and your phone crashes. It's a pretty big deal if you flash your ECU and you lose traction through a turn thanks to some modified vehicle dynamics and kill someone.

I'm guessing the real reason is so they can do some sort of compression between the ground and aircraft. Lossy compression of Facebook and Google images could save a good bit of bandwidth, and they can't do that without intercepting the unencrypted data using this method.

They could say something like this:

Bandwidth at 30,000+ feet is inherently limited, and heavy-load activities like streaming videos from the ground can weigh down our network. That means playback is subject to poor video quality, buffering, and slower connection speeds for your fellow passengers.

Oh wait. That's exactly what they say. They're very up-front about not being able to stream video.

I paid for some GoGo on a flight recently. The signup page made it pretty clear that data speeds were pretty limited and I wasn't allowed to stream video. I don't know why they need to spoof certs for that as opposed to just blocking sites or protocols though. Maybe they do some sort of data compression on the ground before transmitting to the plane or something?

No, it really is kind of a big deal. WebMD is for-profit and largely funded by advertisers such as pharmaceutical companies. The site uses clickbait-style headlines to drive page views and actively preys on fear.

Time to take stock. Go home with some office supplies.
