Future Computer Systems and Networking Research in the Netherlands: A Manifesto

For the past year, we have been working on a Manifesto on the future of Computer Systems and Networking research in the Netherlands (CompSysNL). The CompSysNL Manifesto is now online [1]; a 2-page executive summary ready for sending around is also available [2]. We are a large, cross-institutional community of scientists and technology experts (30+ co-signatories, 7 universities, 5 research institutes and organizations, etc.) Also check out who’s who in CompSysNL [3].
