EU Blockchain Observatory and Forum Blockchain AMA

The EU Blockchain Observatory is a recent initiative, launched in February 2018, which is backed by the European Commission with the primary aim of educating the EU's public on Blockchain technology.This very interesting AMA really served that purpose by answering  the public's challenging questions, which were mainly tweeted under the #AMABlockchain hashtag. Educating the public aside, the forum's two other objectives are to accelerate the application of this technology at a pan-European level and to push for cooperation between member states to materialize uses cases and scenarios backed by Blockchain.

Single Page Application with Perl Dancer

Of course Gabor needs no introduction, but it's worth mentioning that his is a later attempt of publishing a book on the Dancer framework in general. The first one, which I covered in Help Kickstart First Ever PerlDancer Book, was initiated by the Dancer's core devs themselves who unfortunately couldn't generate enough traction therefore the fund raising campaign failed. Fortunately this second campaign by Gabor proved successful to the point of exceeding its financial goals.

From the start you sense that it's going to be a very practical and hands-on tutorial as it doesn't waste any time and jumps straight to setting up the development environment using Vagrant and a Linux VM.Interesting choice considering that nowadays most use Docker, but probably done so because Docker is mainly directed to containerization of applications and not to that of full blown OSs. So after setting up the environment we are next suggested two ways of installing Dancer.The first one is …
