Comment Common Assumptions (Score 1) 713

It seems like the common assumptions in the discussion are:

1) that technology will make everything possible given a long enough period of time.

2) Other species will develop the same technologies.

3) Other species will have the same desires as we do.

I see a lot of these assumptions should be looked at more closely.

For example, some of us aren't that confident in technology solving every issue. We are on a collision course right now with ourselves, in my opinion. If I were asked to assume that life would develop in a similar way as we did, then I would say that the reason we don't run into them, is that they don't survive long enough to get to other solar systems. I certainly hope that we don't make it.

I am reminded of the famous quote by Mahatma Gandhi. When he was asked what he thought about 'Western Civilization' he said he thought it would be a good idea. I hope that contact doesn't happen in my lifetime at least. *shudder*

Submission + - Robot unravels mystery of walking (bbc.co.uk)

manchineel writes: Roboticists are using the lessons of a 1930s human physiologist to build the world's fastest walking robot.

Runbot is a self-learning, dynamic robot, which has been built around the theories of Nikolai Bernstein.

"Getting a robot to walk like a human requires a dynamic machine," said Professor Florentin Woergoetter.

Runbot is a small, biped robot which can move at speeds of more than three leg lengths per second, slightly slower than the fastest walking human.

Bernstein said that animal movement was not under the total control of the brain but rather, "local circuits" did most of the command and control work.

Submission + - Linux Gains Completely Fair Scheduler (kerneltrap.org)

SchedFred writes: KernelTrap is reporting that Ingo Molnar's Completely Fair Scheduler, or CFS, was just merged into the Linux Kernel. The new CPU scheduler includes a pluggable framework that completely replaces Molnar's earlier O(1) scheduler, and is described to "model an 'ideal, precise multi-tasking CPU' on real hardware. CFS tries to run the task with the 'gravest need' for more CPU time. So CFS always tries to split up CPU time between runnable tasks as close to 'ideal multitasking hardware' as possible." The new CPU scheduler should improve the desktop Linux experience, and will be part of the upcoming 2.6.23 kernel.
