I have installed a Geforce GTX 750 on my Windows 10 PC, reinstalled the Lunatics package and is now crunching SETI@home tasks. In the stderr.txt I see that the nVidia driver is 353.54. Is this OK? I did nothing to install drivers, Windows 10 did all the work.

Arecibo has capabilities for sending a planetary radar beam, like the Goldstone antenna of NASA. They were recently used to watch an asteroid. The powerful laser beams of Livermore might be visible at great distances, but the Lawrence Livermore Laboratory has other things to do.

Arecibo and Green Bank are radiotelescopes, they cannot get laser beams. But there is an optical telescope at Lick Observatory which can also send laser beams.

AFAIK lasers are used in the optical interferometers such as LIGO in the USA, Virgo and Geo600 in Europe and one in Japan to detect gravitational waves. In the high power laser field Berkeley Livermore National Laboratory is the top, with a goal to attain nuclear fusion. Europe is going the tokamak way with JET and ITER, but also with Stellarator Wendelstein II in Germany, recently inaugurated by Angela Merkel, a physicist and Federal Republic of Germany Chancellor.

A joule is an energy unit. A billion joule seems too big to me. Maybe you mean a billion watt, given the very short time of the laser pulse.

Since all my SETI@home GPU tasks on RADEON were failing, I uninstalled the Lunatics package and changed GPU to a Geforge GTX 750 which seems to work well. Can I reinstall the Lunatics package changing the GPU setting or is it best to wait for the new package?

Caltech runs the Jet Propulsion Laboratory in behalf of NASA, so most USA unmanned missions are managed by Caltech.They have lots of experience and what they affirm must be taken seriously.

You cannot teach new tricks to an old dog. I know Italian, English, French, Spanish and some German from my youth and loves, but I cannot start studying Russian, although I have a vinyl disk of the Soviet Red Army Choir.

Every new particle accelerator, every new telescope such as JWST is always a prototype. There is no assembly line of accelerators and telescopes. I've read on the latest "Nature Physics" issue of February 2 what is inside the Lisa Pathfinder which is now at Lagrange point one and is being checked before starting physical observations. There are two masses in free fall at 38 cm distance which send laser beams to each other to measure the relative distance which might be altered by a passing gravitational wave. This is only a "proof of concept" experiment, in the eLISA configuration they would be aboard three spacecrafts in a triangle, with each side a million km long.They are testing it to prove that the idea is sound before spending millions of euros/dollars on the spacecrafts and their launchers. Lisa Pathfinder was launched by a mostly Italian Vega launcher from the ESA Kourou base. This proved the reliability of Vega and now eleven are in order, giving work to Italian and French industries.

All SETI@home GPU tasks are failing on my Windows 10 PC with 24 GB RAM, AMD A10-6700 with 2 AMD/ATI graphics, Caico (board) and Devastator (onboard). I have installed the Lunatics application for a 64-bit CPU. Formerly, stock applications would run, even for a long time. SETI@home sees both GPUs, Einstein@home only the Devastator. I plan to eliminate the Caico board and install a Geforce GTX 750 board which I already have. But the Power supply on this HP Pavilion 500-152ea outputs only 300 W, and the Geforce brochure says it needs 400 W, so I should also install a new power supply, and this makes me nervous, because it is difficult to intervene on there cramped boxes (a minitower). My SUN M20 workstation,vintage 2008, is more easy to work inside.

I've crunched an AP task on a guest SuSE Linux 13.2 on a Windows 10 host with AMD-V enabled, via Virtual Box. Unfortunately, the guest does not recognize the CPU which is SSE3 capable, an AMD A10-6700 at 3.7 GHz, so it too a long time (233,865 s).

A British firm of the Google empire, DeepMind, has produced a software, AlphaGo which has beaten the European Go Champion. Go is very popular is Asia. It is played on a 19 x 19 lines board with white and black pebbles. I don't know its rules but there are more possible configurations than atoms in the Universe, so says "Nature" and I must believe it. The software is based on the Deep Learning concept of neural networks. The hardware is unbelievably tiny compared to that of the IBM BlueGene computer which in 1997 beat chess champion Kasparov. The WIRED magazine, without giving many details, says it consists of a network including 1200 CPUs and 170 graphic boards.A match with the World Champion of Go is slated for next March.

The ladies slalom at Maribor is progressing in wet snow while the men Giant slalom at Garmisch-Partenkirchen has been abolished for the same reason. Too dangerous.

This item would cost me more than the HP Laptop 635 which cost me 269 euro.
