I can think of a service that let's people upload his/her photos on some site and this site would then ID the photos uploaded to him/her. That is sites like social networks, dating sites, and online galleries can then verify if the photo is an original by verifying a hashed version of a photo to the service.
To review a language/framework that I know, I write small programs using a few of its features while learning the said language/framework. On my free time I would then browse/review those codes using a source code viewer app installed on my smart-phone.
As an aside. I just noticed that site features mostly inspiring and positive stories. The world definitely needs more news like those.
One good thing about the internet is that we can pick the kind of news that we like.
I refuse to listen to news mediums where fear and negativity are the main focus. The world is a wonderful place if we look at the right places. (Cofirmation bias anyone :)
