A Galaxy Ejects Its Black Hole

Link. “The galaxy, CID-42, is believed to be the product of a collision between two galaxies. In the wake of that collision, gravitational waves are propelling the black hole out of the galaxy at speeds of several million miles per hour.”

Good exercise for a grad class in general relativity: What is the kinetic energy of the black hole in which reference frame?

The death of webOS

Link. They were dead before HP bought them, but even if they hadn’t been this would have killed them…

“We told HP we needed better displays [for the Pre 3]. They’d come back and say, ‘Apple bought them all. Our suppliers tell us we need to build them a factory if we want the displays’ and they weren’t willing to put the billion dollars upfront to do that,” one source said. “The same thing happened with cameras. We’d pick a part, turns out Apple picked the same part. We were screwed left and right.”

SOHO Organizer for iCloud use on Snow Leopard ($100)

Link. Macintouch: “.. SOHO Organizer runs on the iMacs, and the standard Apple Address Book and iCal apps run on Lion and IOS 5 equipment with both sets of apps talking to each other. In other words, you only need to run the SOHO Organizer on the non-iCloud capable machines.

Also SOHO Organizer does not appear to support push notifications. That is, SOHO Organizer syncs on a time schedule rather than immediately after a change has occurred. However, the Lion laptop and the IOS 5 iPhone do communicate with push notifications. I have SOHO Organizer set to sync every 5 minutes, so when it syncs, then iCloud pushes out the change to the Lion laptop and my iPhone very quickly. I am still learning about SOHO Organizer but it seems to do the job.

Others have noted other methods of moving Snow Leopard machines to iCloud. I have not tried it, but for a small group of machines, fruux (https://fruux.com/) might work without having to buy an application. I would be interested if anyone has tried it.”

Not cheap! $100 individual, $180 family. Cheaper than replacing a machine though. Works on 10.5.8
