I thought you were trying to show they had achieved scientific results.

They have. Do the search and read the many papers on various results. Or in your case is "science" limited to finding ET?

Did you look in the scientific literature?

I think you are trying to imply that there is something there. Go ahead and cite it. We will all be interested, I am sure.

Do your own search. Google will search scholarly publications if you read the manual. Try by author and use the project scientists names.

Ah, Tuesday again.

It can't be we've not had an outage. Everyday is the same under the lock down.
Wash your hands and keep your social distance.

When I posted, it was the outage. Just minutes long.

Great news. They have wasted enough electrical energy on an impossible goal, as I have posted in their forum a few times.
But they have good signal processing capability, if some astronomers can figure out how to make use of it.

SETI has done more than looking for aliens.
A lot of their data helped other astronomy research.

I doubt it. I have looked for that on their forum for years, and even asked about it, with no response.

They've had that issue before, basically the camera gets knocked off air due to noise and vibration levels and they have to remote onto another camera (after searching through the other camera feeds until they find one that works)

Not the camera that has the vibration issue, the uplink antenna loses lock on the broadcast satellite. After landing no vibration and lock restored.

If you look at the server lists for main & Beta, apart from the server names there is one big difference - Beta lacks the SETI@Home science database. Beta has been used to test/develop new server code as well as the applications, but those have always either been replicas of, or sub-sets of the main database.

Neither does Milkyway have a science DB listed. Which begs where does their science go? Obviously they have a science DB. IIRC the science DB isn't part of BOINC's automatic display code because it isn't part of BOINC and Jeff and/or Matt had to hand add code to display it. Eric did everything on Beta. IIRC when the science DB crashed on Main, Beta hung as well.

I'm guessing that the results do go into the master DB but are flagged as coming from Beta and hence might be ignored in analysis.

Posted 7 days ago by Profile Gary Charpentier
Post:
Virtualbox wasn't designed to have BOINC control it in such a fashion. You will also find if you pause BOINC that virtualbox does not pause.


When I pause Boinc, the CPU stops completely, I just paused a 24 core machine in Boinc, 6 of the cores running LHC Theory tasks under Vbox. The CPU usage went to zero almost immediately.

Also you will find vitrualbox uses all your cores. Remember it is an O/S.


Not sure what you mean by that. It uses what Boinc expects it to. LHC Theory uses 1 core per task/VM. LHC Atlas uses up to 8, depending on my settings, but this is displayed in Boinc, Boinc knows how many cores are allocated to that task.

On my boxes zero isn't zero but 0.xxx. VB never quite goes to zero on its own. Every O/S, and VB is a guest O/S on Doze, always has some stay awake tasks.

As to the active connections issue, while that is IP related I think that is the 127.0.0.1 loopback that is active for inter-process signals and not traffic to outside.

No matter, when BOINC asks VB to shut, which is does when Doze tells BOINC to die from your shutdown, VB is not killing itself. I'm not sure why, but VB is a privileged process and BOINC is not and it may be the signal is blocked by Doze security. Or Doze kills BOINC before it has a chance to ask VB to quit. Or perhaps the reverse and Doze asks VB to quit but it still has active science which it can't kill until it informs BOINC who Doze may have killed by then. Think checkpoints.

PS, none of this BS happens on Linux or Mac, just Doze.

As to VB using as many cores as it wants, it does. While the LHC science app only uses one or however many it declares, every time that science app makes a system call to the O/S, VB in this case, VB uses as many cores as it wants to service that request. VB is not bound by BOINC in this manner. Nor is any O/S and don't forget VB has to call Doze to do the request so Doze will wake up some cores too.

My only suggestion is to pause BOINC, then quit it telling it to quit science. Once that is done, then restart or shutdown Doze. If you get the message then, you know it is VB/Doze issue.

Beta has NEVER fed data into the main science database, despite what some people have thought and said. Much of the work it ran was either a standard set of data, or re-badged completed data, and it is this that may have caused the confusion.

Rob, I do remember years ago Eric said it did go into the science DB. However I don't know if he said so just to get people to run Beta or not. Or perhaps that was only after the app being tested came out of test and was deployed on main.
11) Message boards : Questions and problems : Virtualbox has active connections when shutting down Windows 10 (Message 98849)
Posted 7 days ago by Profile Gary Charpentier
Post:
Whenever I shut down Windows 10, and Virtualbox is in use (eg an LHC task), Windows says "Virtualbox has active connections". I can force it to stop, but if it's a remote computer this is annoying or very difficult to do, and it doesn't seem right to force stop a running project. If I wait, Windows eventually gives up and goes back to the desktop. Sometimes if I try to shut down again, it works, but sometimes I get the same error message again. I've done a Google search and this seems to have been a problem for years. Is this a Virtualbox problem, a Windows 10 problem, a Boinc problem, or an LHC problem?

Virtualbox wasn't designed to have BOINC control it in such a fashion. You will also find if you pause BOINC that virtualbox does not pause. Also you will find vitrualbox uses all your cores. Remember it is an O/S.

Well, I haven't been able to post on Beta, since my RAC dropped to 2.


I visited Beta recently, there are still >2200 Beta Tasks In Progress, including 1 AstroPulse.

Does anyone know if these are needed to complete the final complete data set ?

SETI Beta is currently running.

The fork has been stuck in Seti Beta and it is done. It has been since Feb 26 any work was generated. If those numbers on the status page aren't spurious, and I suspect they are, they are abandoned work which just needs to time out. AFIK all beta work has a cannonical result.

As to what happens to Beta work I've seen conflicting reports as to if it makes it into the master science database or not.

Grumble: two of the cat7 cables I have laid are broken, one gives me only 100Mbit speeds, the other up to 30Mbit! I wish I could go back to the store with them but I threw away the receipt.

Just confirming you are running Cat 7 capable equipment? GigaGate45 connectors?

I'm sure you are, mostly for others who might try and plug Cat 7 into a Cat 5e/6 device.

Looks like you have to download a codec and you can just open them in Windows 10 Photos.


No Windows 10 Photos here. Defenestrated in 1999 and haven't gone back since!

Then I guess you will have to write the codec. That's what happens when you chose free.

Are you like my friend Ronnie? He used to zap any electronic part he picked up. It was either his body or his clothing that was different. I don't think carpet is a problem. I've got carpet here and I've never zapped a thing. Never felt a shock myself either. I never bothered with those anti-static straps, I used to just touch an earthed computer case first, now I don't even bother with that. Modern stuff has diode protection from static.
I get static shocks from my car each time I step out.
Had that static issue at one place a long long time ago. Finally figured it out. The ladies were wearing nylon and polyester. Zap every time. The guys were wearing denim. Answer in the office was somewhat pricey anti-static chair carpet protectors which had a ground wire. Never had another issue. You might check the fabric content of your wardrobe. The other thing you might try is a room humidifier.
