+ - The Paradoxes That Threaten To Tear Modern Cosmology Apart

Submitted by KentuckyFC
KentuckyFC (1144503) writes "Revolutions in science often come from the study of seemingly unresolvable paradoxes. So an interesting exercise is to list the paradoxes associated with current ideas in science. One cosmologist has done just that by exploring the paradoxes associated with well-established ideas and observations about the structure and origin of the universe. Perhaps the most dramatic of these paradoxes comes from the idea that the universe must be expanding. What’s curious about this expansion is that space, and the vacuum associated with it, must somehow be created in this process. And yet nobody knows how this can occur. What’s more, there is an energy associated with any given volume of the universe. If that volume increases, the inescapable conclusion is that the energy must increase as well. So much for conservation of energy. And even the amount of energy associated with the vacuum is a puzzle with different calculations contradicting each other by 120 orders of magnitude. Clearly, anybody who can resolve these problems has a bright future in science but may also end up tearing modern cosmology apart."

+ - Microsoft reveals Windows 10 will be a free upgrade->

The company unveiled the Windows 10 consumer preview on Wednesday, showcasing some of the new features in the latest version of the operating system that powers the vast majority of the world's desktop PCs. The developer preview has been available since Microsoft first announced Windows 10 in the fall, but it was buggy, limited in scope and very light on new features.

Importantly, Windows 10 will be free for existing Windows users running versions of Windows back to Windows 7. That includes Windows 7, 8, 8.1 and Windows Phone. Microsoft specified it would only be free for the first year, indicating Windows would be software that users subscribe to, rather than buy outright.

Microsoft Corporate Vice President of the Operating Systems Group Joe Belfiore showed off some of the new features in Windows 10. While Microsoft had already announced it would bring back the much-missed Start Menu, Belfiore revealed it would also have a full-screen mode that includes more of the Windows 8 Start screen. He said Windows machines would go back and forth between to two menus in a way that wouldn't confuse people.

Belfiore also showed a new notification center for Windows, which puts a user's notifications in an Action Center menu that can appear along the right side, similar to how notifications work in Apple OS X.

Microsoft Executive Vice President of Operating Systems Terry Myerson revealed that 1.7 million people had downloaded the Windows 10 developer preview, giving Microsoft over 800,000 individual piece of feedback.

Myerson explained that Windows 10 has several main intents: the give users a mobility of experience from device to device, instill a sense of trust in users, and provide the most natural ways to interact with devices."

During an amber alert, the more important goal is to find the missing child. It is a weighing of ethics.
Do you go around testing doors to see if any are unlocked? You may get into trouble.
And the site in question is not being visited to notify owners their security is poor, it is much more voyeuristic than that...
