Dolby Digital, Atmos or DTS ... what do these audio technologies hide?

With the multiplication of audio formats, not easy to navigate to make the right choice. 01net.com explains the main ones to make sure you do not go wrong. Be immersed in a match and live the same atmosphere as the stadium? This is certainly what every football lover dreams about in front of his television. If the image participates more and more, including the broadcast of some matches in 4K, the audio is still the poor relation of sports retransmissions. However, we do not buy a TV only to watch football (well, normally). It is therefore good to know what the different formats used for cinema sound mean. Not always easy to cope with the acronyms and logos displayed on the data sheets of the devices or on the pockets of DVDs and Blu-ray discs. These are the latter that will usually give you the most systematic access to multichannel audio formats, with several voices in the front, rear and a subwoofer. Netflix also offers some compatible content, both movies and series. Two...

A hacker has found a way to make system snapshots that can instantly bring Windows 7 and Windows 10 to the knees. Oddly, Microsoft does not intend to fix this bug. Good news for little jokers. Security researcher Marius Tivadar of Bitdefender has released a method on GitHub to crash Windows using a simple file. The expert, in fact, found a flaw in the way Windows handles NTFS system images. He found the bug in July 2017 and immediately alerted Microsoft, but Microsoft did not see fit to fix it. To cause the breakdown, it would indeed "physical access or attack by social engineering," writes the company Redmond in an email. In short, it would not be dangerous enough to develop a patch. Still, this bug is extremely simple to reproduce. Simply put the trapped file of an NTFS system image on a USB stick and insert it into a Windows PC. The researcher has published a file of this type on GitHub with a size of 10 MB. If auto-play is enabled, the system crashes immediately, ...
