In the mid 90s, the average Internet website was mainly composed of static HTML elements and references to images, sometimes to music (MIDI files). Most of the (then) webmasters were mainly concerned about the size of the pictures to be …

Everyone that has a website online, knows something about the question of the suitable webhosting. For the ones who do not know a word about WebHosting, it is a service (free or commercial) that works on a machine (or farm, cloud, grid of machines) allocated inside a Data Center qualified to provide a clean, fast Internet access, reliability, availability (and scalability), all to host a website or group of websites.

Barry Cinnamon, CEO of Akeena Solar recently accepted the invitation to a Q&A round with Scientific American journalist and from his well-informed point of view, it can be extracted the following conclusions …

MINERvA is a complex device built at DOE’s Fermi National Accelerator Laboratory to observe the interactions of neutrinos (v) and is the first phase of functioning with 24 modules already assembled and working.
Right now, MINERvA has been able to catch a glimpse of how the neutrinos interact with the matter. The deadline for the full assembly is 2010, in which 109 2 inches-thick modules will be working to observe the neutrinos, provided by the Fermilab Accelerator Complex.
