Comment: Auction mode (Score 1) 129

by netcruiser (#42824403) Attached to: How To Stop Prediction Market Manipulation
Many exchanges use an auction mechanism to prevent this from happening. When a trade is made that is more than x% different from the previous trade, the security goes into "auction mode" for a period of time. During this period all the bids and offers are taken, but only at the end of the auction, using an "uncrossing" algorithm, is a fair price determined for the security. The auction can of course also be manipulated, but you'll need a lot more money to influence the price.

KDE SC 4.7 May Use OpenGL 3 For Compositing 187

An anonymous reader writes "KDE SC 4.5 is about to be released and KDE SC 4.6 is being discussed. However, Martin Graesslin has revealed some details about what they are planning for KDE 4.7. According to Martin's blog post, they are looking at OpenGL 3.0 to provide the compositing effects in KDE SC 4.7. OpenGL 3.0 provides support for frame buffer objects, hardware instancing, vertex array objects, and sRGB framebuffers."

Astronomers Discover 33 Pairs of Waltzing Black Holes 101

Astronomers from UC Berkeley have identified 33 pairs of waltzing black holes, closing the gap somewhat between the observed population of super-massive black hole pairs and what had been predicted by theory. "Astronomical observations have shown that 1) nearly every galaxy has a central super-massive black hole (with a mass of a million to a billion times the mass of the Sun), and 2) galaxies commonly collide and merge to form new, more massive galaxies. As a consequence of these two observations, a merger between two galaxies should bring two super-massive black holes to the new, more massive galaxy formed from the merger. The two black holes gradually in-spiral toward the center of this galaxy, engaging in a gravitational tug-of-war with the surrounding stars. The result is a black hole dance, choreographed by Newton himself. Such a dance is expected to occur in our own Milky Way Galaxy in about 3 billion years, when it collides with the Andromeda Galaxy."

What is worth doing is worth the trouble of asking somebody to do.
