A multi-language site

Starting from today, I added multi-language support to RobertoBifulco.it. Clearly it is always a drupal service, which provides a good support for these things with the internationalization module.
So here is the first post published in two languages!
Link Multiplexing in a Xen-based Network Emulation System
Roberto Bifulco — Sat, 05/08/2010 - 17:00
Network emulation has gained wide interest in the community of network researchers to evaluate the effectiveness of new protocols and applications in controllable and realistic network scenarios. To ensure scalability, modern emulation systems rely on the use of virtualization techniques to create complex networked systems by means of the computational resources available in a cluster of computers. In the context of network emulation systems, link multiplexing is the problem of emulating multiple point-to-point connections on top of a single Ethernet link.
Dynamic Virtual Cluster reconfiguration for efficient IaaS provisioning
Roberto Bifulco — Sat, 05/08/2010 - 16:49
Cloud computing is an emerging paradigm to provide Infrastructure as a Service (IaaS). In this paper we present NEPTUNE-IaaS, a software system able to support the whole lifecycle of IaaS provisioning in a Virtual Cluster environment. Our system allows interactive design of complex system topologies and their efficient mapping onto the available physical resources of a cluster. It also provides transparent VM migration features across geographically distributed datacenters, thanks to the adoption of the Service Switching paradigm.
Lavorare meglio per lavorare meno

Da diversi anni ormai sviluppo software in Java, in progetti piu' o meno vasti e complessi. Una delle mie principali preoccupazioni e' sempre stata la ricerca di una valida soluzione per l'organizzazione del lavoro. Come spesso capita quando si portano avanti piu' attivita' allo stesso tempo, infatti, si ha la percezione che la confusione generata dal passaggio da un impegno all'altro possa rallentare la produttivita', o rendere comunque difficile il perseguimento degli obiettivi di progetto.
