Not exactly — though it’s easy to see why a well-resourced company would want to.
Why? Because, quite frankly, there is nothing else quite like YouTube. Sure, there are some competitors in the video space that are open platforms with video embed functionality like Dailymotion and Vimeo. But neither have the competitive scale.
But as we’ve learned repeatedly over the past year, YouTube is not exactly the best for building a profitable business if you rely solely on it for revenue. And where there’s weakness, there’s opportunity.
And there’s a handful of companies gunning to take a bite out of YouTube’s business.
Astronomers have witnessed a triplet of monster black holes swirling in the center of a distant galaxy, a new study says.
Astronomers have learned over the past decade or two that virtually every full-size galaxy such as our own Milky Way has a giant black hole lurking in its core. These monsters weigh in with a mass equal to millions or even billions of stars.
The new observations, however, described in the journal Nature, suggest that many galaxies have not one, but two or more giant black holes in their centers, orbiting each other in a tight gravitational dance that will ultimately lead the objects to merge together into something even more gigantic.
Watching these mergers will offer insight into how gravity behaves when stretched to its limits, astronomers predict, with clues revealed by monster black hole mash-ups such as the just-discovered triplet.
"We were quite surprised to find it," says Roger Deane, of the University of Cape Town in South Africa, lead author of the report. In one sense, Deane and his colleagues shouldn't have been surprised. It's widely accepted that when galaxies come close together, their gravity can force them to form a single agglomeration of stars. In fact, the Milky Way and the (relatively) nearby Andromeda galaxy will probably experience such a merger in about four billion years. Since each galaxy hosts a single massive black hole, the resulting single galaxy should end up with two.
Deane and his group originally became interested in this particular galaxy, known by the unwieldy name SDSS J150243.091111557.3, because it had been flagged by the Sloan Digital Sky Survey (thus the "SDSS" in the name) as having what looked like two sources of bright light in its core.
That indicated the possibility of two black holes there, with the light coming not from the invisible objects themselves but from the whirlpools of gas heated to incandescence as they spiral in under the black holes' intense gravity. Jets emitted by the black holes pinpointed their location.
Video has become an incredibly common part of everyday life. People take videos on smartphones, upload them via YouTube, and share them on Facebook. You'd think, then, that free video editors would be common, but it turns out the selection is limited for anyone not blessed with Mac OS X (and, as a result, access to…
Also, if you can, check out Cyberlink Power Director (my favorite, though usually not free). ;-)
If you're familiar with Linux Ubuntu, you may know that they had a free file upload and storage service called Ubuntu One. I recently got this email about the closure of this service. If anyone has used it, remember to retrieve your files.
As previously announced, the file services for Ubuntu One have been discontinued. Your data is available for download until the end of July - if you haven't taken action already, you need to do so now in order to ensure you have a copy of all your data.
In order to make it easy for you to retrieve all of your content, we have released a new feature that lets you download all your content at once. Our website (https://one.ubuntu.com/) has been updated with instructions on how to conveniently download all your files.
In addition, you still can use Mover.io's offer to transfer your data to another cloud provider for free. And the Ubuntu One web interface is available for you to download individual files.
The previously announced option of downloading your files as a zip file is producing unreliable results for a small number of users and therefore we have removed that option. If you already retrieved your files as a zip file, we encourage you to check for the validity of the zip file contents. If there are problems with that file, please use one of the options above to retrieve a complete copy of your data.
Remember that you will have until 31st July 2014 to collect all of your content. After that date, all remaining content will be deleted.
We know you have come to rely on Ubuntu One, and we apologise for the inconvenience this closure may cause. We've always been inspired by the support, feedback and enthusiasm of our users and want to thank you for the support you've shown for Ubuntu One.
The first quantum transmission to go via space paves the way for ultra-secure communications satellites. Secret encryption keys transmitted via quantum links provide the ultimate way to communicate securely. That's because any attempt to intercept the key will be revealed thanks to the laws of quantum mechanics, which say that interception will introduce changes that give away eavesdroppers.
The technology is already available for fibre-optic cables, but a truly global network would need satellites to beam quantum data between distant locations. To test how these might work, Paolo Villoresi at the University of Padua in Italy and his colleagues turned to satellites covered in ultra-reflective mirrors. These are normally used to bounce laser beams back to Earth. The time they take to return shows up any shifts in gravity.
The European Space Agency (ESA) has released a new image from the Planck telescope, which at first glance could easily be mistaken for a frothy swirl in a coffee cup, but in fact depicts the Milky Way’s magnetic field lines, and could help...
