... Really? MB vs. AP ? You think with AP it's easier or more/better possible to find ET? |

Weather can affect crunching as well. Not if you have a well heatsink/fan combi on CPU.. well fan-RPM in the GPU-case.. and well airflow through the PC-case.. ;-) |

... I think we have no way of knowing if ET is using narrowband or broadband transmissions, and assuming one and not the other just reduces our chances of finding a signal. |

... I think that if we are trying to find intelligent life, that there is a probability that they started with narrowband transmissions like we did, but that broadband would probably be a larger portion of their "history" (remember, the data we are sifting through is thousands of years old, if not older). But like Ned said (hey, that rhymes!), eliminating either choice will seriously hinder our efforts in finding ETI. |

I know that the project has been down for maintainence but 1 of my rigs is having problems downloading new tasks keeps getting an error (has wrong size). My other rig has been trying to upload and report 4 tasks.(TEMP FAILED SERVERS MAY BE DOWN) I have checked the servers and they report all running. Any ideas I have run out of cuda on the first rig. {edit} by the way my stats are 100k out on credits |

Its Tuesday .... maintenance day when the servers are down during most of the day. On restart there is always a backlog as everyone hits the servers for refills etc. A good url to watch this happening is the cricket graphs at: http://fragment1.berkeley.edu/newcricket/grapher.cgi?target=/router-interfaces/inr-250/gigabitethernet5_1&ranges=d%3Aw&view=Octets Regards Zy |

Thanks for that Zy. I didnt have this problem in the past with the errors. But I guess it will clear.I just ran out of CUDA. |

Narrow band signals have the ability to travel farther and are easy to discern from the background noise. Wide band signals are used more when you need a higher density (and low power) of users like in our phone systems. CDMA uses something like that. Military spread-spectrum uses something like that. Those evolved transmissions will look like noise anyway to our software, I don't think we have the capability to find ET thru that. AP it is not looking for ET in my opinion. I really think that something else it is going on here... |

Narrow band signals have the ability to travel farther and are easy to discern from the background noise. Considering that any sufficiently advanced civilization will be using narrowband for such a short time (even shorter on a cosmological scale), I'm not certain I can agree. If AP is not looking for ET "in your opinion", and you think its looking for something else, it might be helpful to back your opinion up with facts and data, otherwise its just speculation and conjecture to be discarded. [Edit] Personally, I'm not certain why there's such a large resistence to change with SETI@Home, and why the conspiracy theories abound because of a new application. Wouldn't SETI@Home want to focus on finding ET? Do you honestly think that SETI@Home would be so dishonest to "sneak" something else in to fool the participants? It simply doesn't make sense, which means the logic just isn't there to support the hypothesis. |

It's my opinion we are looking for signals about equivalant to our I Love Lucy signals that are travelling out into space. There is no telling what our space buddies are using for communications nowadays. They may have given up on radio waves centuries ago. PROUD MEMBER OF Team Starfire World BOINC |

Narrow band signals have the ability to travel farther and are easy to discern from the background noise. Wideband signals are very easy to generate, still travel a long distance and dont need sophisticated receivers. As our first radio transmitters, spark gap generators are extremely wideband, travelled all around the world with low power and were detected with very simple equipment. Sounds like an ideal way of saying "Can you hear this". |

And we're back. That was fun. Wonder who tripped over the power cable this time? Read Matt's latest tech post. Some spider/bot was trudging through the site and brought the MySQL database to a halt. Linux laptop: record uptime: 1511d 20h 19m (ended due to the power brick giving-up) |

Cricketgraph shows a drop in server throughput, and schedular could not connect to server.Same as last night for me. Hope someone is still at home. LOL Server status still reporting all on. Dave {edit}Message from server no Enhanced or Astropulse |

This is a shame. The latest speculation in Technical News is that it was a rogue stats-bot scraping the pages, instead of downloading the nightly xml dump as it should. That one's been blocked - hooray - but these reports, and the slow access to forum pages I'm seeing, suggests there's another one. Boo. |
