A Turing machine (TM) is a very simple kind of computer, * but despite its simplicity it can do anything * that the computer you are reading this on can * (it will probably be slower, but it will work).

"Decentralization transfers that power from individuals and corporations to technology and immutable math, leading to reduced overheads, improved security, more resiliency and higher efficiency. There are three technologies that will form the foundation of the decentralized computing stack - mesh networks (decentralized networking), block chain (decentralized transactions) and autonomous agents (decentralized decision making)."

"The Microsoft Alternatives project (MAlt) started a year ago to mitigate anticipated software license fee increases. MAlt's objective is to put us back in control using open software. It is now time to present more widely this project and to explain how it will shape our computing environment."

As reported by Nesta, an innovation charity with a mission to help people and organisations bring great ideas to life: As technology shapes our world, young people need to be able to shape it too. As skills and work become increasingly technologically mediated, the need for digital skills is paramount with some calculating a potential £2 billion loss to the UK economy from unfilled roles requiring such skills. After several years working with organisations supporting digital making, and with creating with technology set to go mainstream through a forthcoming BBC campaign, this report takes stock of what is happening. Key Findings: 82 per cent of young people say they are interested in digital making. However, half of young people make things with digital technology less than once a week or never. Parents are overwhelmingly supportive of digital making. 89 per cent think it is a worthwhile activity for their children. 73 per cent encourage their children to make things with technology. We identified 130,800 opportunities to experience digital making provided by the organisations surveyed. This is a long way from providing for the interest shown by 82 per cent of our survey, which represents a possible 8.2 million school age children and young people in the UK. Digital making is powered not just by money, but also by volunteers. Two thirds of the organisations identified said they relied on volunteers to do their work. Only half of teachers who teach ICT or computing report being confident in teaching the curriculum.

"This questionnaire enables your company to determine the current situation and shows you whether you are implementing the most important technical, organisational and employee-related measures for a minimum level of cybersecurity protection. Rather than focusing on a comprehensive and complete analysis, this is a way for SMEs - especially those with little in-depth understanding of computing and IT security - to quickly and easily find out whether their technical, organisational and staff-related measures provide sufficient protection against cyber-risks. Learn in the Cybersecurity guide how you can better protect your business against threats from cyberspace and use the free tools of the GCA Cybersecurity Toolkit to make your business more secure today."

Richard Stallman shares how he has created the first free operating system, and explains how nonfree programs give companies control of their users and what users can do in order to recover control over their computing Quotes: Nowadays, computing is so important in society that the freedoms of free software are among the human rights that society must establish and protect.

La capitale allemande est devenue un passage obligé des hackers et activistes du net, en s'imposant comme une anti-Silicon Valley.

Le numérique constitue une rupture technologique majeure, sans doute aussi importante que la découverte du feu ou de l'agriculture !

"Parmi les ruptures récentes, on citera le passage de la télévision à l'ordinateur personnel (PC), du téléphone au smartphone, du logiciel qu'on installe sur son ordinateur aux outils 100 % en ligne sur le web (aussi appelé « nuage », en anglais : cloud computing). Le numérique constitue une rupture technologique majeure, sans doute aussi importante que la découverte du feu ou de l'agriculture ! Un postulat que nous osons émettre ici..."

"Le terme de « technologie de rupture » (disruptive technology en anglais) fut introduit et argumenté par Clayton M. Christensen dans son livre The Innovator's Dilemma, publié en 1997. Dans la suite de son ouvrage, intitulé The Innovator's Solution, Christensen utilise le terme plus générique d'innovation de rupture parce qu'il reconnaît que peu de technologies peuvent être effectivement dites de rupture ou de continuité. C'est au contraire leur usage effectif qui peut avoir un effet de rupture"
