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.

Mario Torelli, dell'Universita' di Perugia, ha ricevuto il prestigioso Premio Balzan di 800000 dollari per l'archeologia classica. Altri vincitori sono David Tilman per l'ecologia, Dennis Sullivan per la matematica e Ian Hacking per l'epistemologia.Il premio viene assegnato da una Fondazione con sedi a Zurigo e Milano e comporta l'impegno di destinare meta' della somma a finanziare la ricerca di giovani collaboratori. Naturalmente nessun giornale italiano ne ha dato notizia.
il Premio Balzan viene assgnato ogni anno a cultori di scienze diverse. Per il 2015 sono previsti premi per l'ocenografia, l'astrofisica, la storia dell'arte europea e la storia economica.

Yes, but it seems there is an excess of positrons in a given energy range.

My latest PC, a HP Pavilion 500-152ea is simply a black box, so there is no need to show pictures. But I think its 2 TB disk, placed vertically and bolted to a chassis, is a Seagate hybrid disk, with a SSD cache of 8 GB. The HP datasheet of a similar box, the Pavilion 500-240el, says it has a 16 GB SSD cache, but the datasheet does snot specify the make. Anyway my new PC runs well with its AMD A10-6700 CPU at 3.7 GHz and produces less heat than my SUN WS of 2008 vintage and my HP 635 of 2012 with its AMD E-450 CPU at 1.6 GHz. The SUN has a very reliable Opteron 1210 at 1.8 GHz. 8 GB RAM on all three, DDR2 on the SUN and DDR3 on the HPs.
