Whitelisting is indeed much nicer and more straightforward. Allow access only to certain sites. Since Wikipedia is generally not acceptable (as of now), access should instead be given to reputed sites such as that of WileyInterscience, Nature, Popular Science, HowStuffWorks, etc.

Comment Re:Sometime the old ways (Score 1) 330

Universities WOULD have a good record educating people because they mostly take well-educated, disciplined, & hardworking students - in other words, students who have already learnt to be successful - at least in certain areas. The hardest work is in Primary education where it is now recognized that much of the foundation for later life is laid. They are bound to attract criticism. Though, I believe, that there are too many factors involved and too many things to do for just one type of institution to shoulder the entire burden. Parenthood, Religion, Government, Commerce & Industry, Citizens Action Groups, Seniors Groups, etc should all pitch in to shoulder the responsibility for the all-round growth of every new born right from the moment of birth till the age of 15 or so. This needs to include giving worthy Primary teachers the same salaries as their colleagues in Universities with the same qualifications. I contend that when a person is shown how and then facilitated to be successful on their own, they would rather not cheat. The requirements are for people who are as skilled as those who are teaching at University. In fact, teachers at University should ONLY be part-timers who love facilitating young adults so much that they will do it for free. These teachers must necessarily possess expertise and experience in either Research or Application. Society must instead devote its funds and concentration on a person's life from birth to age 15 or 18. That's it. After that, the person, now a young adult, hopefully having been made strong, courageous, disciplined and wise, can now fend for themselves - first in the academic and then in the professional world.

Grad Student Invents Cheap Laser Cutter 137

An anonymous reader writes "Peter Jansen, a PhD student and member of the RepRap community, has constructed a working prototype of an inexpensive table-top laser cutter built out of old CD/DVD drives as an offshoot of his efforts to design an under $200 open-source Selective Laser Sintering (SLS) 3D printer. Where traditional laser cutters use powerful, fixed-focus beams, this new technique dynamically adjusts the focal point of the laser using a reciprocating motion similar to a reciprocating saw, allowing a far less powerful and inexpensive laser diode to be used. The technique is currently limited to cutting black materials to a depth of only a few millimeters, but should still be useful and enabling for Makers and other crafters. The end-goal is to create a hybrid inexpensive 3D printer that can be easily reconfigured for 2D laser cutting, providing powerful making tools to the desktop."

Thanx for taking the trouble to inform me, ppanon. That made for exciting reading. Also, I realized just how poorly informed I am. :D

I'm now pretty sure that there MUST be a project for establishing a space factory which could be used for many other purposes including building photovoltaic cells of higher efficiency than now possible (probably because of the Earth's gravity). Would you know of any such?

Also, the dark side of the moon has featured as a base & launchpad for in-system missions in many sci-fi novels. Why is it that money is NOT being concentrated on building such a base with mines, refineries, factories, etc.?

Why would an advanced (for their time) knowledge of medicine & surgical practices preclude the belief in magic?!?!? Humans are quite individualistic and so it would be quite wrong to assume that there would be a uniformity in beliefs. There have always been AND are always going to be differing groups of people REGARDLESS of the age/era/whatever.

Some might have believed in magic, some in God/gods, and others in science.
