Awesome review! Truly enlightening. Before I saw this article, I had absolutely no idea what Pentaho was, or why I would want it. Now, I know exactly what I'm getting both my friends for Christmas this year. I can't wait to discuss all 492 pages of this treasure with them in the new year.

A Wireless Hotspot For Your Car — Why Not? 135

nk497 writes "UK mobile operator 3 has unveiled a wireless hotspot for cars. It's essentially a repackaged version of their MiFi wireless router, which lets users create their own wireless hotspot using the 3G network. While drivers will hopefully steer away from using the web at the wheel, 3 predicts the mobile hotspot will let passengers entertain themselves as well as offer a hookup to email, music and traffic data."

That's nice, and when the oil runs out to power the machinery and civilization that can build windmills, batteries and solar panels, then what? You think you can build a wind turbine with wind power?

Uh, yeah. That's kind of the whole point of building an alternative power infrastructure. Energy is energy, whether it comes from oil, from a solar panel, or from dogs running on a treadmill. It takes a certain amount of energy to construct a wind turbine, and the source of the energy has no effect on the quality of construction.

Look, I get what you're trying to say. Even if I had a self contained wind turbine factory out in my back yard, and all I had to do to build a wind turbine was to hook it up to a battery, feed it some input materials and push the "Start" button, I would still have issues. I could charge the battery with a wind turbine or a solar panel or some dogs running on a treadmill, but I would still need those input materials, things like copper wire, aluminum and steel, in sheets and blocks, circuit boards, etc. Some of those inputs are still very much products of a civilization that runs on oil, whether it is in their manufacture or in their transport. So yeah, if the oil ran out tomorrow, we'd be screwed.

However, the oil is not going to run out tomorrow. We can use the oil infrastructure of today to build the alternative energy infrastructure of tomorrow. This isn't as huge a task as one might think. The world's factories will run just as well on hydro-electric power as they will on coal-electric power. The real issue is going to be transportation, since most industrial transportation is based on oil powered vehicles. It's a long way to China from New York. But even this isn't as bad as one might think. If Brazil can run on ethanol, then so can anyone else. Then there's biodiesel. Either one of these alternatives will work in current fossil engines, so we can incrementally wean ourselves off oil before it starts to become scarce.

Our ultimate goal should be to have a manufacturing infrastructure that is independent of its energy source. Energy should be a generic input to the industrial machine, just like the material inputs. That way when the oil runs out, we can build our wind turbines with wind power.

It's also a matter for the police, but it is still a matter for the school. The school is charged with maintaining a safe environment for the students. I am not condoning what the school has done but they should be looking out for illegal activities that could harm other students. Where they went wrong is with the invasion of privacy that occurred when looking for illegal activities.

I agree. Children often make mistakes. They need to be protected from their inexperience. The school is merely filling the role of a big brother, who naturally wants to guide and protect his younger siblings from the dangers of the modern world.
