Smart boards are triggering the IoT revolution, allowing to make common objects and things smart through their network, storage and processing capabilities. arduino boards have a prominent role in this revolution, due to their customizability and programming freedom. From a different perspective, another strategic development for the IoT is towards Cloud, allowing to properly manage things and data ubiquitously, on demand, as services. Pushing in this direction, we can pave the way to the Cloud of Things, where real things, rather than the data they produce, can be provided to third parties, by adopting a "device-centric" approach. To this purpose, virtualization of physical resources becomes an essential step and core mechanism. In this paper we focus on smart board virtualization, implementing a flexible solution for arduino boards based on Stack4Things, allowing to create, multiplex, migrate and deploy virtual boards in IoT-Cloud contexts. The results obtained by a preliminary implementation and experiments on the #SmartME testbed are shown in the paper to demonstrate the feasibility and the effectiveness of the proposed solution.

Ornamental aquaculture is an economically important industry with many enthusiasts worldwide. Much of the supply for the industry is provided by individuals and businesses in tropical countries because many ornamental species originated in the tropics. But Czechia, a temperate region in Central Europe, is an exception. Czech suppliers have significantly influenced the global freshwater ornamental aquaculture market for decades. Here we present and discuss the history of ornamental aquaculture in Czechia considering its geopolitical background, social status and history, pet-trade trends, overlapping to research activities, public education, and related risks and threads. We list the most traded and exported species, and list species that rarely reproduce in captivity, but that are successfully bred for commercial purposes by Czech producers globally, we introduce the term "Czech aquarium phenomenon" to describe the substantial economic and scientific importance of Czechia in ornamental aquaculture. Given that the diversity and volume of species traded are vast, we suggest the importance of this phenomenon for consideration to key stakeholders who design aquaculture policies, including the management of invasive alien species and ex-situ conservation programs for endangered species.
