 Hi everybody, I'm Jen with opensource.com and I have a brand new top five articles of the week for you today, August 19th. At number five, four alternatives to ghost for disk cloning. Jason Baker says that disk imaging and cloning doesn't require an expensive tool or a proprietary one. In this article, he lays out four open source alternatives for your disk imaging needs. At number four, Godot open source engine helps power the future in West Virginia. Godot is ideal for group learning in the classroom. In this article, find out more about how West Virginia is using Godot as it rolls out its first ever coding app and game design curriculum for schools. At number three, let's encrypt. Why create a free automated and open CA? During the summer of 2012, two guys decided to start a certificate authority or CA, which acts as a third party to issue digital search certificates. Learn more about why and how they started let's encrypt, now one of the larger CAs in the world. At number two, top five open source web servers. Did you know that open source powers a lot of the web? Probably, but had to ask. You can get an introduction to five of the most popular open source web servers out there from our writer Scott Nesbitt. And finally at number one, what is copy left? You've probably heard or seen the term used copy left, but maybe you're not sure exactly what it means between copyright open source licenses and permissive licenses and a lot more. It can get pretty murky. Become the envy of all of your friends by learning all about copy left and more in Ben Cotton's introduction. Alright, that's it for the top five this week. Thanks so much for joining me and I hope to see you next time.
