Scott McNealy, the former SUN boss whose Onyx computer with UNIX I have used from 1981 to 1985, said that had Solaris been free Linux would not even exist. I am using a free Solaris 11.1 with its ZFS file system. I am using KDE on Linux and Gnome on Solaris.

Tullio would I be correct in saying all fundamental particles have a antiparticle and therefore that would include gravitons ?

Gravitons are not particles (fermions) but bosons (force carriers). There are fermions which are their own antiparticles and they are called Majorana fermions, from Ettore Majorana who made this hypothesis before disappearing mysteriously in 1938. Enrico Fermi called him a genius in a letter addressed to Mussolini asking to put the police on his search. He was never found.

I am running VirtualBox on my Linux system and one of my Virtual Machines is Solaris 11.1 running a BOINC client and a SETI@home app by Dotsch. The BOINC client is a line command edition, no GUI. I think Solaris is vastly superior to Linux, but since it used to cost a lot of money, developers preferred Linux and so there are very few BOINC projects using it.

A Vicenza arriva da solo Giovanni Visconti. Sempre Nibali in rosa.

I had a dual boot PC with Windows 98SE, which I used for the MS Flight Simulator, and Linux. Then Windows went to XP, Vista, Windows7, etc. and I gave the whole PC to my son so that his son could learn to fly.

Absolutely, Vesuvius has erupted seriously over thirty times since the famous 79 AD event, which makes it, on average, overdue. And the longer the time before it does will make it more explosive.

Also, the area around it is heavily populated. It would become a nightmare to evacuate it even with a two or three days warning.

As I wrote on the other thread, you don't have to install Linux if you want to join the Test4theory@home project. Just install the VirtualBox for Windows and then register to the project. Most of its volunteers are Windows users. I am using SuSE Linux but CERN uses Scientific Linux which is RedHat plus some scientific libraries.

No, if you are using Windows you must load VirtualBox for Windows, then register to the project. The Virtual Machine (BOINC_VM) vill be downloaded automatically and you shall see the CERN jobs running in a window, if you don't choose the headless mode. You shall see one Penguin or 2 Penguins in the window, depending if you use one or two cores. This depends on your BIOS.

Personally I wouldn't want to live anywhere along tornado alley. Neither would I want to be near the San Andreas fault, or the Yellowstone Caldera. And you can add the slopes of Mount Etna to that list. But, people do, and if people wish to, then it makes sense to give them as much protection as possible.

Mount Etna is not dangerous, as it is discharging its lava with frequent eruptions. It is Vesuvius which it is dangerous. Last eruption was in 1944.

I am using SuSE Linux, but since BOINC for Linux is compiled with Ubuntu maybe that is the best choice for a Windows user. You don't have to install additional libraries, as I have to do. There was a project for a Standard Linux, but I never heard from it in recent times. Linux is going the UNIX way, so that every vendor is adding something or deleting something to be unique. Bad choice.

You shall have to install VirtualBox from Oracle on your system. Then you have two choices, either to run the standard Test4theory@home wrapper (default) or choose the beta wrapper. I am running the first on 2 Linux boxes with BOINC 6.10.58.If you choose the Beta wrapper you must have the 7.0.xx BOINC.

Tappa di rientro in Italia, a Ivrea. Vince Benat Intxhausti, Spagna-Movistar. Nibali semore in rosa, male Santambrogio.

I'm still confused, though. The article linked below, is from a popular level, but I hope scientifically respectable magazine. It says in the first paragraph that mass is conferred on all matter by the Higgs. http://www.scientificamerican.com/article.cfm?id=could-lhc-discover-higgs-boson

The so called dark matter (or missing mass, according to Fritz Zwicky, 1935) could be made of WIMPs, weakly interacting massive particles, which could get their mass from the Higgs field. But we are still in the area of speculation.

AFAIK the Higgs field only gives mass to leptons, not to hadrons. Since normal matter is made up from hadrons such as protons and neutrons and electrons, which are leptons, I doubt very much that this effect could be achieved. The LHC is now in an upgrade phase, hence not working, but we are still analyzing data from it in the test4theory@home BOINC project. I have so far simulated 200 millions events (collisions). But the LHC produced 600 millions collision/second.So there is still a huge amount of data to be analyzed by the LHC Grid, which does not include the volunteers, but has a worldwide network of computers.

Il Campionato di Serie A e' finito con la vittoria della Juventus. Il Napoli e' secondo e partecipa anche lui alla Champions League. Il Milan e' terzo e dovra' qualificarsi per la Champions League. Torna in A il Verona (Hellas Verona) e vi arriva il Sassuolo per la prima volta. Un'altra squadra sara' scelta fra Empoli, Brescia, Novara e Livorno.

I know that the European Space Agency has built a launch capability for Russian Soyuz launchers at Kourou, French Guyane, home of the big Ariane launchers and also of the Italian built Vega small launchers. The Soyuz is halfway between the two.

Giovanni Visconti (Movistar) vince sotto la neve sul Galibier, davanti al monumento a Pantani. La tappa e' stata accorciata di 4 km, ma e' passata sul Moncenisio innevato. Nibali sempre in maglia rosa. Domani riposo.

Earth strikes that could level a city or a state are a lot more common than one in 60 million years. What if the Tunguska strike had occurred over Moscow, London, Paris or New York? That size event is within our power to prevent. As a side effect space programs around the world would benefit from the improvement in technology.

NASA is going to launch a mission OSIRIS-REx to an asteroid in order to bring back a sample of its material for evaluating the danger of it striking the Earth.

I;ve just signed a contract. 15.5 eurocents/kWh (Plus VAT) until 220 kWh/month and 31 eurocents/kWh beyond that. But I am mostly under the 220 limit with two Linux boxes running 24/7. No AC.
