Can Free big data regulate AI and the data economy?

Market does not seem to provide any valid solution to the new issues posed by a data economy which is characterised by a combination of increasing returns and legal blockers to community or ecosystem based competition. As a consequence, the current known optimal organisation to monetise big data and A.I. is the private or state monopoly. We review in this article possible alternatives that could be considered in the future and how to enforce them.

Five Evolutions of Cloud Computing

Cloud Computing is essentially the automation of IT service provisioning through software which replace human tasks. It is currently evolving in multiple directions. Free Software and Open Hardware will eventually lead to massive price cuts compared to current price levels in USA or Asia. Edge Computing will reduce the need of data centres whenever network latency or availability become critical. Service Workers will eliminate the need of servers, both at the edge or at the data centre, in 90% cases. Big Servers will eventually replace smaller servers as the standard fabric the data centre.

OfficeJS Iodide: Ubiquitous Data Science Notebooks for Business and Education

Iodide and Pyodide have brought a standard notebook application to OfficeJS that can be used for business reporting, research and education. They support data science libraries such as NumPy, Pandas, Matplotlib, Plotly, etc. and soon scikit-learn. OfficeJS Iodide notebooks can be used offline or online on any modern HTML5 web browser such as Firefox or Chrome. Thanks to JIO, notebooks can be synchronised with Dropbox, WebDAV, ERP5 and any other storage supported by a JIO plugin. Iodide notebooks can also be embedded through RenderJS into any business application. The dream of ubiquitous data sciences at no infrastructure cost has come to a reality.
