So you claim now, the city of Fukushima got hit by a mag 9 quake? Is that your claim? So what mag had the quake/epicenter 450 miles away?

Look, this is like claiming that a 250 horsepower car is 3 horsepower, if you stand a few hundred feet away. Or a hot dog has a lot more energy content, if it's on your plate rather than on some other plate halfway across the restaurant. You're completely ignoring the meaning of earthquake magnitude. It doesn't mean peak acceleration.

So you claim now, the city of Fukushima got hit by a mag 9 quake? Is that your claim? So what mag had the quake/epicenter 450 miles away?

The city/precinct whatever of Fukushima did get hit by a magnitude 9 earthquake with an epicenter some distance away. There's no "claim" to it. That's just what happened.

If you like to live in a pipe dream that it is possible for humans to build a "construction" that can survive a mag 9 quake: dream on!

I can do a whole lot better than that. It is possible to construct a oil tank that can survive a direct hit by the asteroid that killed off the dinosaurs. It requires some heavy duty sci fi bullshit and geological eras of time, but it's doable.

Cool the Earth down to room temperature - all the way to the center of the planet. Then drill a 4000 mile long hole, drop your 50,000 gallons of oil in there, and presto! you have an oil tank with 4000 mile thick walls. Your average extinction level asteroid impact isn't going to do much more than scuff the paint.

Now, normally, it'd go without saying that nobody would do that, just like most people don't build tanks to withstand magnitude 9 earthquakes. It's not "pipedream" territory, but it is costly and impractical.

And this brings us back to the earliest post in this thread:

Gas tanks. Oil Tanks. Diesel tanks. Cleaning supplies. Light industrial supplies.

Just to name a few of the blatantly obvious. Those chemicals are ubiquitous. Every flood of a modern habituated area is an 'environmental disaster", you just don't hear about it.

Even Germany with its vaunted regulations has this problem - every single time it floods. The regulations keep that level of normal accidental release of pollutants at a tolerable level - which is their purpose.

But I find it ridiculous that you then glibly downplay the huge earthquake and tsunami flooding on the basis that well the earthquake isn't actually that big (despite having an energy release roughly 30,000 times greater than your frequently cited hypothetical example of a point blank magnitude 6 earthquake) and flooding is flooding whether it be a rather sudden 15 meter surge of water (capable of pushing around large buildings and tanks) or a few centimeters of river overflow puddling in the street down the road.

Technically, it's just where you're buying the connection. Netflix are already at a shitload of peerings.

AS2096 - 170 peers -

AS55095 - 2 BGP peers -

So now I'm even more confused to WTF they're bitching about.

Kidding aside, you make a great point!

The length of a quake has nothing to do with its magnitude.

That depends on what you're doing. If you're integrating earthquake power over time, then it does matter. There's an obvious time dependency in that case, for example, the earthquake can continue (releasing yet more energy) rather than stop.

For reference: the Fukushima earthquake was slightly above 9 on the Richter scale, no idea on what measurement it was on MMS

Magnitude 9.0.

You are the one arguing that a quake 450 miles away from its epicenter has the same power as at the epicenter ... ignoring the fact that it then, by common logic, would have the same power 1000miles away, and 10,000 miles away and 25,000 miles away ... on the other side of the globe.

And I've already corrected you on this misconception. Why continue to claim such things?

Blanket bricking of cell phones, or selective bricking of those of "ringleaders", is an inevitable problem for the most peaceful and well behaved political rally with this kind of technology in government hands. Remember the "Arab Sping", and Tianenmen Square, and even the more recent and quite peaceful "Occupy Wall Street" the US, and understand exactly why and how law enforcement want this kind of power.

Comment: Making Silent Running drones for gardening (Score 1) 132

A post from me to comp.robotics.misc in 1999 about Silent Running drones which spawned a thread with 32 messages:
Anyone remember the drones (Huey, Dewey, and Louie) from the sci-fi movie Silent Running?

Some links: ...

They have always captivated me, and were an early influence in getting me interested in robotics and AI.

I particularly liked the scene where all three worked together to perform a medical operation.

I've long wanted to build some robots like these for gardening and maintenance. It seems to me that multifuncional drones such as those (with changeable end effectors) would be very valuable in agriculture, by reducing the need for pesticides and fertilizers through picking off pests, pulling weeds, and spot applying fertilizer, and by not compacting the soil like tractors.

Has anyone given any though to what it would take to make such drones today?
How much would it cost to build such a system (part cost, design time cost, assembly time cost)?
How long would it take?
How much could it lift?
How long would the battery (fuel cell?) life be?
How well could they be made to walk or climb stairs with today's technology?

Anyone out there started such a project to clone these drones?

Any advice on where to find more information on their design, or maybe the originals made for the movies?

Would that design concept (one armed, collaborative walking robots, three feet high) now be considered obsolete (i.e. compared to the post model in Hans Moravec's latest book "Robot")?

Could a business case be made today for a company to build such robots? Or instead, would anyone be interested in collaborating on an open source design for robots that looked like those?
