Probably not once after creating Web application you would like to put it on a remote server. Personally, I like to use for this services of openshift (httpss://www.openshift.com) in the case of the free version it allows registrations of 3 projects and supports such containers as Tomcat, Jboss or WildFly and there is no problem to hook up a database. For larger projects there is a paid version of these services. Unfortunately the service may at first seem quite complicated but in this may help present tutorial.
Did you ever needed to move real objects from your surroundings on to your computer, and I’m not talking about the pictures but a fully three-dimensional model. Possible for 3D printing. There are for this purpose special 3D scanners, but in most of theme prices starts from a few thousand, and few of us can afford them. One day I was looking for cheaper alternatives and it turned out that this can be achieved by using affordable solutions.
