Sony's Clever but Flawed PlayStation Copy Protection--And How They Might Have Fixed It
 
14:15
You can support this channel on Patreon! Link below The original PlayStation is a pretty neat thing. Using the CD as a storage medium was a smart move. But, Sony needed to add anti-piracy features to the disc to prevent miscreants from making bootleg copies of Crash Bandicoot. This video tells the story of how that works, why it wasn’t infallible, and also proposes a potentially impervious solution (24 years late, though). Here’s that paper on reading optical discs. It’s a good read: https://pdfs.semanticscholar.org/f772/6d20c43b22fb13f8788c8c64df2dbe9fa44f.pdf You can support this channel on Patreon! Patrons of the channel are what keep videos like this coming.

Is It Safe: To Live in Russia

Today we are trying out a new series called Is It Safe. We're looking first at the life in Russia and if it is safe to live there. Let me know what you think of this series SUBSCRIBE TO US -► http://bit.ly/TheInfographicsShow If we do our homework well, not only will this be a good way to learn about a country we might know little about, but perhaps bust some myths regarding stereotypes, and give our viewers relevant and useful information about a place they might want to travel to someday. We picked Russia because this is the first example our viewer gave us, and it’s certainly a place that is widely discussed and possibly even mischaracterized. Today we’ll bring you all the latest statistics, see what the media is saying, and look at what Russians are saying on forums, in this episode of the Infographics Show, Is It Safe: To Live in Russia?

While Everest isn’t generally considered to be the most difficult peak to climb (that honor probably belongs to either Annapurna in Nepal or K2 on the China/Pakistan border), it is the most famous and, as such, sees the most people attempting to scale it each year.

Top 10 Most Incredible Time Capsule Findings
 
11:55
Whilst time machines don't exist (yet), time capsules are the closest thing we have in reality to them, so lets find out the most incredible time capsules! Subscribe for more! ► https://goo.gl/pgcoq1 ◄ Stay updated ► https://goo.gl/JyGcTt https://goo.gl/5c8dzr ◄ For copyright queries or general inquiries please get in touch: hello@beamazed.com Be Amazed at these amazing time capsules! Steve Jobs Time Capsule - This time capsule might not be the oldest on this list, but it might be the most recognisable just by its name alone. Detroit Century Box - We obviously have our own ideas about what the future holds for humanity, but what did people from 100 years ago expect our own time to look like? Oldest American time-capsule - The sad truth is that not every time capsule is opened when they’re supposed to be opened. 1950s mental hospital - When you think of time capsules, your first thought probably isn't creepy - but trust me, this one definitely is. Expo 70 Time Capsule - So in 1968, two Japanese companies, Panasonic Corporation and The Mainichi Newspapers, decided to celebrate the 1970 Japan World Exposition. Whisky - Its surprising how many time capsules include alcohol. It turns out, whether it's a crate of beer or a bottle of whisky, adding a tipple for the people who discover your capsule is a pretty popular idea. The Westinghouse Time Capsule - Another time capsule that is not to be opened for 5000 years is the Westinghouse Time Capsule, which is housed in what is called the Immortal Well. Oldest message in a bottle ever found - Messages in bottles might be a cliché - but in real life they come up far less often. The Crypt Of Civilisation - The Crypt Of Civilization definitely has the coolest name of any time capsule in this list, but it also has one of the most interesting stories. Paris Opera & MIT capsule - The Paris Opera is already famous for having a ghost that stalks around in the basement, but there is another ancient thing buried down there as well.
