I don't understand why they would even want to install Windows 7. My Windows is 91 versions more up to date! |

Thanks. :^) Phil Plait of the Bad Astronomy blog published a nice piece on this today: Have Tunguska Meteorites Been Found? I Have My Doubts. Definitely worth reading. |

This is widely regarded as a meteorite exploding in the air before hitting the ground. I think that the consensus among astronomers is that it was a piece of a comet. Comets are mostly made of ices... frozen water, methane etc. When they hit earth's atmosphere, the water and other ices turn into superheated steam causing a steam explosion, and of course flammable methane would then explosively react with the oxygen in the atmosphere. There would be little to no residue and a very small (considering the size of the explosion) or no impact crater. This fits what happened at Tunguska best, and as a bonus satisfies Occam's Razor. :^) |

I've occasionally had a card downclock to 405MHz even after I solved the overheating issue; was able to get it to stop doing this by reinstalling the drivers using the clean install option. And I wouldn't run a card 24/7 over 70C either unless it's an old one you can do without. |

AVG gave false positives before too. Yup, I linked to VirusTotal's results in the OP... no detections, even from AVG's main engine. But I think it's still better to have this info posted so it's a known issue. |

mm no prob's here with AVG I noticed it says reboot to finish action !! AVG hadn't just done a update did it just before it flaged it ????? I think it means by that because it's a running process that it needs a reboot to remove or quarantine it. Always exclude the entire BOINC data directory from scanning, that keeps all problems regarding AV away. I'm sure the developers are trustworthy, but what if their compilers are compromised, for example? (Yes, this has happened.) |

 Using Lunatics platform. The module catching this is Identity Protection. Unfortunately there are no details provided. (The field cut off on the right edge just says "File or folder" as the object type, not what is triggering the detection.) I ensured it wasn't quarantined, yet I can no longer find this file at the location indicated, but instead in the oldApp_backup subfolder. For some reason the C:\ProgramData\BOINC\projects\setiathome.berkeley.edu has become read-only. I ran it through VirusTotal after re-extracting it from the original download archive, verified it has the same hash as the one in oldApp_backup, and it came up clean with 0/46. So it's probably a false positive. |

Fastest / lowest-impact way of getting rid of the bad update on Vista/7/8/2008/2012 (not XP): Open a command prompt (CMD in the program name if you can't find it; admin. privileges required obviously) Then type in or paste: wusa.exe /uninstall /kb:2823324 /quiet /norestart Press Enter and you're done. Could be turned into a tiny .BAT of course too. |

Also perhaps the fora name of Number Crunching should be changed to Number Crunching & Assistance. The "Politics" forum would also benefit from being renamed to "Politics and Religion" as this is where the threads on the latter either start or get moved to. Most forums have them clumped like this as they are the inflammatory subjects that need constant watch from the moderators. |

I've been trying to start a fundraiser for whatever hardware would be required to get the Green Bank project going (there was some data collection and analysis but it wasn't distributed to us so was very small-scale and preliminary.) So far, I've never had to work so hard to give money away. :^) Things are in transition so I'll have to sit tight until they settle down. What I'd really like to do, though: The GPUUG upload/download servers which also include NTPCKR are just about $19K away. I could definitely commit $5K to a matching fundraiser once they are closer to $15K. It would have to be a 2-for-1 ie for every $2 donated I would donate $1... just a poor working IT man. :^) But before I ponied up that kind of change, I would need assurance that it would be put to use, ie that NTPCKR would run 24/7 and also be run on all the years of archival data, and of course that the results would be used! Once the project is settled into its new home, I'll see if that can happen. I'm not interested in just chucking results in a database to collect dust either, and although I love astronomy and all the science, that isn't the primary reason that I'm here. I think that the assurance would go a long way to keeping many of the volunteers on the project as well, never mind just my donation. |

Gravitational lensing has been observed. Indeed, it has become an important tool in the astronomer's kit-bag. Ah... I knew there was one I was missing from gravitational redshift, time dilation, the equivalence principle and relativistic frame-dragging, all predicted by G.R. and confirmed by observation (some of which to a high degree of accuracy.) |

You can start by watching the following: Doesn't really lead anywhere. His main point is that Einstein's field equations are a one-body solution, but the universe isn't one-body, so therefore they don't work. He doesn't explain why they don't. You can determine the gravitational attraction of a single mass in G.R. because it is a factor of the curvature of spacetime, without needing a second unit mass to pull against as Newton's gravity does. He's also forgetting the ample confirmation that Einstein's field equations do work. Attempting to disprove General Relativity mathematically is all well and good, but it has so far passed every test that has been thrown at it (ie gravitational redshift, time dilation, the equivalence principle, relativistic frame-dragging.) If he has a good point, he should publish and be subjected to peer review, also explaining why experiments that confirmed G. R. are wrong, or how his hypothesis could explain them better. This is how science is done, not by making YouTube videos. He does have a point about black holes though: they don't *really* happen, and I'd better qualify a blanket statement like that... there's nothing wrong with the General Relativity behind them, rather, there's a component of General Relativity itself that scientists who discuss black holes always overlook for simplicity's sake: gravitational time dilation! Here's the not-too-difficult equation for gravitational time dilation:  r0 is the Schwarzchild radius of the body, at which point the escape velocity becomes c, the speed of light, r is the radius of the body (the collapsing star in this case), t0 is the passage of time within the star and tf is time outside. The important component of the equation is the last one. As the star collapses, r approaches r0 so the fraction approaches 1, and thus t0 approaches zero, asymptotically. Why asymptotically? Because t0 is the passage of time within the star, which is approaching zero. So, seen from the outside, a collapsing star would *appear* to form a black hole. As it collapsed, it would appear to do so more and more slowly, and get redder and dimmer until it was invisible, at progressively lower frequencies until it was completely undetectable by emission. It would be a tiny fraction away from being inside its own event horizon/Schwarzchild radius, but to actually get there would take an infinite amount of time. It would have all of the properties associated with a black hole by being a few billionths or so of a part away from actually being one, but it could never actually get there for an outside observer. The only way to even to try see it get there would be to jump into one! The observer (assuming they weren't instantly ripped to pieces by the tidal forces) would catch up to the timeframe of the collapsing star, which then could be seen to enter its own Schwarzchild radius. By doing this, an eternity would then pass outside and the universe would end! So it may not be possible at all. Do primordial true black holes exist? I'm not sure. But the math is pretty clear that point masses and infinite gravitational densities can't form, at least while we are watching! Because of this effect, the astrophysicist George Greenstein proposed that black holes be called "frozen stars" instead. So, it turns out both "sides" are correct. Black holes do exist as collapsed stars where the escape velocity is 99.9...% of c (and you can pile as many 9s after that as you like), the emission of photons is an undetectable few per year (also approaching zero as time passes) and all the other properties assigned to and confirmed through observation from black holes are there (gravitational lensing, jets, emissions of X-rays from matter pulled into it, etc.) as well as the (asymptotic) approach of infinite density and gravitational field strength, but they don't exist insofar as we can never have enough time to actually get to that last tiny fraction of completeness, never mind infinite density! I hope this puts the "controversy" to rest but I doubt it will. ;^) |

If I remember correctly the original announcement about the possibility of making this move, it would allow for more bandwidth for downloads (I could be wrong). I hope so... there ends up being even more traffic if there isn't enough bandwidth due to all the retries (ie uploads don't resume.) That would be a great improvement and well worth the outage. |

Let Einstein have a burst. Just put it on NNT after one work request. I just set it to a resource share of zero. Then it only grabs work units when SAH doesn't have anything to do for either CPU or GPU. Sometimes E@H is a little too generous on the CPU side but the GPU side units will only download one at a time like this, and never if SAH has one ready. |

Whatever was done last night, I had a load of downloads in queue at 17h00 PDT and although the upload server went offline, the downloads stayed going for hours and they all completed. So no complaints here. :^) That was an unexpected bonus. |
