OK, but what Einstein objected to is the "Copenhagen interpretation of quantum mechanics", which raised objections also by David Bohm and others.This why he said "God does not play dice".

I am running 7 BOINC projects on 3 PCs, two Linux and one Windows 8.1..Only two of the 7 projects use graphic boards, while 2 projects from CERN use Virtual Box, and it seems that also CPDN is aiming at that solution, from what they said at Budapest. Only the Windows PC has a graphic board, the Linux boxes have not and they run CPU only tasks. All 3 have Virtual Box.

But he refused quantum theory, because it is based on the idea of chance,God does not play dice, he said (Gott erwulfelt nicht,if I am not wrong). If your read Jacques Monod's "Chance and necessity" you may understand how old was his mentality.

They were proposed by Ettore Majorana in 1937, one year before his disappearance that was never explained. He went from Naples, where he had the chair of theoretical physics and very few students, to Palermo, leaving a letter in which he announced his suicide. Then from Palermo he sent a telegram to a colleague saying he would be back but never arrived again in Naples. Enrico Fermi sent a letter to Mussolini asking that the police would search him amd Mussolini wrote on the letter "I want him to be found". Fermi had described Majorana as a genius and he was. Leonardo Sciascia wrote a book on Majorana describing him as someone feeling guilt for the development of nuclear weapons but Majorana had nothing in common with nuclear research. I believe that the reason for his suicide could be found in a book by Thomas Mann, "Doktor Faustus". After all, theoretical physics is very close to music.

There is tomorrow a BOINC meeting in Budapest where Rom Walton will speak about Virtual Machines in BOINC. He is a developer of the CERN projects but appears to be from UC Berkeley.

My SUSE has sent me a patch for Bash and I am trusting them. They send me regularly updates on my 13.1 version on 2 Linux boxes. I am using a 64-bit Windows 8.1 on a third PC to run ATLAS@home which needs a 64-bit Virtual Box and also vLHC@home, so CERN is happy. I am running also LHC@home on this host.

I used C shell and Korn shell on my UNIX systems but Linux uses Bash.

I think there is also a European mission on the way to Mars, whose sky seems to be crowded. But only America has two missions already on the ground.

In my electricity bill I pay for the decommissioning of the 4 nuclear reactors we had in Italy and whose fuel elements are still waiting for a depository, that nobody wants in his backyard.

I think I read it on the JPL site. There was also a photo of the SSL building atop a hill and overlooking the San Francisco Bay. Beautiful location.

Downstairs I have an electronic meter which records the instant power rate and adds it for the bill. It is read at distance by ENEL (the state utility) I believe via Ethernet on the power lines. Once in the Nineties a friend engineer had built a modem which used the power lines to connect devices, but he found that the wiring inside houses was too unreliable to use for data transmission from one room to another, so he abandoned the idea.

I've read that 4 instruments aboard MAVEN were designed and built at Space Sciences Laboratory, UC Berkeley.

Tullio you using one of them electric lawn mowers !, they do use a bit of power depending on the motor in them .

I think it uses 800 W, if I remember well.

I used to consume 170 kWh/month with 2 computers without graphic boards. Now I have a third PC with a graphic board and the total has risen to 243 kWh/month. All three run 24/7. I pay 32 eurocent/kWh with a 40% discount on the first 220 kWh/month, that is 19.2 eurocent/kWh.
This in summer, with no AC but with more frequent washing machine and lawn mower use, so maybe the fault is not all on the graphic board.

Funny, theregister.co.uk gives credit to Andrej Linde for the inflation idea.

Non sono un fanatico di opere ma adoro Maria Callas, donna brava, bella e sfortunata. Era innamorata di Pier Paolo Pasolini, che era omosessuale. Fu abbandonata da Onassis, ch le preferi' la Jackie Kennedy e mori' ancora giovane. Ma quando ascolto "Casta diva" di Bellini vive ancora.

Riccardo Muti non dirigera' Aida e Le Nozze di Figaro all'Opera di Roma. Troppe opposizioni e troppe richieste corporative da parte di alcuni sindacalisti. Sta troppo bene a Chicago, dove dirige una delle orchestre top five. C'era un bel film di Fellini su questo tema, mi pare Prova d'Orchestra. Purtroppo noi italiani mandiamo all'estero i nostri uomini migliori (Marconi, Fermi, Rubbia, Faggin e ora Muti). E' autolesionismo, ci vorrebbe uno psichiatra.

ATLAS@home volunteers lamenting for lack of work have been informed that a powerful thunderstorm on Saturday night has brought down many CERN servers, including their own. So even CERN is subject to the forces of nature

I am running SETI@home and Einstein@home on a HP 635 laptop 24/7 using SuSE Linux 13.1. The only change I did was to upgrade the RAM to 8 GB and to install a 250 GB SSD by Samsung instead of a 320 GB hard disk at 5400 RPM.
