Stephen Hawking: 'There are no black holes' Artist's impression VICTOR HABBICK VISIONS/SPL/Getty The defining characteristic of a black hole may have to give, if the two pillars of modern physics — general relativity and quantum theory — are both correct. Most physicists foolhardy enough to write a paper claiming that “there are no black holes” — at least not in the sense we usually imagine — would probably be dismissed as cranks. Peter van den Berg/Photoshot “There is no escape from a black hole in classical theory, but quantum theory enables energy and information to escape.” In its stead, Hawking’s radical proposal is a much more benign “apparent horizon”, which only temporarily holds matter and energy prisoner before eventually releasing them, albeit in a more garbled form. “There is no escape from a black hole in classical theory,” Hawking told Nature. Hawking posted his paper on the arXiv preprint server on 22 January1. Fire fighting Beyond the horizon Now Hawking proposes a third, tantalizingly simple, option.
Convert Old PC To Network Attached Storage with FreeNas One of the biggest problems still plaguing the environment today are the mass amounts of electronics being tossed out on a daily basis. This goes for everything from cell phones to televisions to your outdated stereo system. While stuff like cell phones and iPods can be easily sold, it’s the personal computer that still lacks consistent recycling. The majority of both business and home PCs are typically either thrown out with the everyday trash, or turned over to one of the few electronics recycling warehouses in your area. These warehouses usually require some type of fee for disposal as well. Until we get some type of environmentally friendly method for computer recycling, I am going to recommend trying your own way. FreeNas is an open source NAS (Network Attached Storage) operating system. Once installed, you have a large plethora of options to choose from. Have any of you used FreeNAS before?
programs.clearerthinking.org/introduction.html#.Ux5-V_mSySq Have you ever wanted to make better decisions? Start right now. Over the last several decades, scientists have discovered a slew of systematic errors in human thought. These idiosyncrasies affect everyone; unchecked, they can cause serious, life-altering problems for you and the people you care about. Each of Decision Academy's courses will help you rein in a different type of mistake that you probably didn't know you were making, or teach you a reasoning skill that largely isn't taught in schools. Interested? Judging by the people who have taken this course in the past, you will likely need between 7 and 20 minutes to complete it. 50% of the people who took it finished it in 12 minutes or less.
BitTorrent Sync Although not touted by the developers as an intended direct replacement nor competitor to cloud-based file synchronization services, it has attained much of its publicity in this potential role.[2] This is mainly due to the ability of BitTorrent Sync to address many of the concerns in existing services relating to file storage limits, privacy, cost, and performance. History[edit] On 24 January 2013, BitTorrent, Inc announced a call for pre-alpha testers to help test a new "distributed syncing product to help manage personal files between multiple computers".[3] Several private pre-alpha builds of "SyncApp" were subsequently made available to a limited group of alpha testers between January 2013 and April 2013. On 23 April 2013, the previously private "alpha" was opened up to general users[2][4][5] As of 6 May 2013, more than a petabyte of anonymous data had been synced between users, with over 70 terabytes synced daily.[6] On 27 August 2013, BitTorrent Sync for iOS was announced[9]
Comparison of file synchronization software This is a list of file synchronization software. File synchronization is a process of ensuring that files in two or more locations are updated via certain rules. Definitions[edit] The following definitions clarify the purpose/meaning of column names used in the tables that follow: Name: Either just the product's name or, if part of a larger product line, the name of the product line and the specific offering. Protocol: Protocols supported by the product. Programming Language: What computer programming language was used to write the software, if known. Windows: Indicates whether the product runs under Windows operating systems. OS X: Indicates whether the product runs under Mac OS X. Linux: Indicates whether the product runs under Linux variants. Other OS: Indicates whether the product is supported under any other operating systems. License: Indicates the licensing model under which the software is published. Sync to cloud: Is there a "cloud storage" option? Open source[edit] Freeware[edit]
