If it weren't for Frank, I'd be filthy rich. When the first microcomputer chips came out in the early 70's I joined the Homebrew Computer Club, along with Steve Jobs and Steve Wozniak. Everybody in Homebrew became ultra-rich, except me.

While other homebrewers were designing and selling the first home computers, I spent my time figuring out how to utilize the first computer chips for SETI experiments, thanks to Frank. I didn't become rich, but instead I was inspired by Frank to work on some of the most fundamental questions we have as humans. He taught me so much - I was incredibly fortunate to work with Frank on many SETI experiments for 45 years. Frank's insights led to optical SETI, SETI@home, and most recently, while in his 90's, Frank helped pioneer PANOSETI.

Frank was a wonderful friend, mentor, and brilliant collaborator. If Earthlings ever find ET, we'll have Frank to thank.

3rd consecutive day of no boinc stats update

Thanks Eric for the news. Out of interest are big is the storage capacity in George M?

The server Centurion handles the Green Bank Telescope data, do we know yet what the Parkes data server will be called?

What's the hurry? We've got all the time in the world.

I hope everything works out as well Eric thanks for the update.

Out of curiosity when everything is working as it should between Greenbank and Berkely are all of the tapes shown on the server status page transferred is one file or are they transferred individually (but all downloaded at the same time)
Thanks in advance. I appreciate you taking the time to answer

Related to Green Bank ... What did you find with the Slow splitting and deletion of GB data?
It appears the system has got back up to normal speeds.

Let us know if new hardware is needed Eric. We can certainly mount another donation drive as we proved there is earnest commitment to the project on the last one.

Still nothing here in New Zealand... I have 2 computers dedicated to running data and they are getting bored waiting for work... LOL.
Seriously, what is happening??

Yes, Jeff ran into some snags with the data. Matt's unavailable to transfer more data from GBT until tomorrow.

Splitter seem to be down to me....

I dunno, seriously considering moving most of my hardware to F@H. I just get back into DC with new equipment.. ThreadRipper is idle yet again. I don't remember that SETI has been down for so long or had so many problems... Been doing S@H for over 15 years with various accounts and hardware.

Perhaps you guys have enough volunteers to do the WU's you need and my resources could be used elsewhere.

Thanks.

I don't know in what format the Green Bank data is stored. If it is on physical drives, couldn't you just overnight them via FedEx? Assuming you have the correct hardware on your end to mount them and get the data into the splitters, wouldn't that keep us going for a few more days until campus networking gets off their Level One script reader response?

I am pretty sure that during the campaign all the donations collected from anywhere are going towards it.

I don't like the looks of WU 2739307008. One host successfully downloaded and ran it. Everybody else is getting D/L errors on it, 5 hosts so far. My machine's Event Log shows:

I just downloaded the WU manually and didn't seem to have any errors. The file doesn't appear to be truncated, either, ending with "</workunit>" as the last line.

I just downloaded it as well. I got a manual MD5 of 450a32005c6700d7ab95284edc959572, the same as BOINC calculated for yours: that would suggest that the MD5 stored in the database when the file was created (so that the comparison can be done) might be corrupted.

EXCEPT: the person who downloaded the _0 replication got a clean download. _1 was a file size error (my download was 720,530 bytes, which is close enough without knowing the precise number of bytes expected): all the others got the MD5 error.

Which suggests that something was messing with, either, the database MD5 values, or, the stored files on disk. Neither really bears thinking about, and both are a long way outside our control. As Rob says, take the day off.

since about 2 days it started it has become very slow
my pc has just turned itself off and shut down
and independently removed 2 annoying suspicious entries

Now read that again, "300TB storage/splitting system @ $30,000", which is not just drives. There's the drives' enclosure/s plus what ever CPU cores are necessary to cater for it as well as all the hardware required for the splitters. There's a lot more to it than what you have read into it. ;-)

Cheers.

do you know if Seti@home might one day be allowed to receive data from China's new radio Telescope ?

Got 4 of them, 3 of those ran for 13,14 and 15 seconds before finishing. Triplet count: 30.

Let's hope that it's not really 75% of them that do that.

Is the double size the new standard then?

The (mostly) archaic second-person singular possessive pronominal adjective is “thy”, not “thine”.

Dude...the SPLC has about as much credibility in the real world as teh Black Panthers do.

you might want to keep in mind you live in one of the most protected environments on the planet..a uni campus and while many o the people there love the SPLC, the more general public, in examining some of the SPLC's calls, are deciding that they are a little less than objective.

Dude...the SPLC has about as much credibility in the real world as teh Black Panthers do.

white supremacists

You F**KED UP saying the above.

would it be feasible for the creators and managers of S.E.T.I. and/or B.O.I.N.C. to look around for another university or similar research facility to host these various scientific projects?

Don't these people check with their peers before publishing? and its a shame they don't go through the same vigorous thought processes as your good self , although i note there is still a very slim chance that they may be correct the odds are that they are not as you explain so well.

• It is persistent. It appears at the same spot in the sky in multiple observations.
  
• It only comes from one spot in the sky.
  
• If we reobserve the target, the signal is still there.
  

Things that add to believability

• Its frequency/period/delay does not correspond to known interference.
  
• Its Doppler Drift rate indicates that it is exactly frequency stable in the frame of the center of mass of the solar system
  
• Its properties (bandwidth, chirp rate, encoding) indicate intelligent origin.
  

Unfortunately the observing method used by the Russian team does not permit many of these things to be determine. 1. The signal was not persistent. 2. The signal was gone when the target was reobserved. 3. The signal frequency/period/delay cannot be determined. 4. The signal Doppler drift rate is unknown. 5. Many sources of interference, including satellites, are present in the observing band.

People that were working primarily on SETI@home have transitioned to Breakthrough,

Obviously I'm confused, Eric. I thought SETI@home and Breakthrough were part of the same effort. I take it they're not. (?)

Without having some sort of NITPCKR running 24/7, analysing data REALTIME (o r as close as we can get), it’s a waste of out time anyways.

Would’nt you agree ?

Awesome! Just a quick question. Any way to get back our own custom screensaver wallpaper if we had added that?

Does the "_OFF_" indicate an observation taken off-target to give an induction of the local background?

Could someone please explain the information in the new file names on the SSP?

I see. Pity that BOINC doesn't able to parse clInfo in right degree to see that HD4xxx hardware present. As one can see from app's own output it is doable.

Oh Berkeley. :'(

• Nobody elected us. I'm a scientist. I don't have the right to speak for the people of Earth even though I have access to a telescope that could. Same goes for any group of scientists. There's even a Declaration of Priciples that SETI scientists supposedly adhere to that says I won't transmit a message in response to a signal without global agreement. The representatives of the people of the world (the UN General Assembly) need to set the rules.
  
  
• The proposal ignores that human civilization changes over time. If we are broadcasting signals that could be returned in 1200 years, we will not be the same civilization in 1200 years. According to the Guardian, at the meeting, one of the proponents said "a civilization only three hundred years ahead of ours could detect Earth’s TV signals at a distance of 500 light years." If that's the case, won't we know through other means if there is a technological civilization around the stars they target long before our signals even arrive there?
  
  
• Nobody will be listening for a response. 1200 years ago, the Caliphate was at its maximum, and Muslim scholars were deriving algebra based on Hindu texts. Charlemagne was Emperor of the West. The Chinese were inventing printing using wooden blocks. Matches had not yet been invented in Europe. There was a civilization in North America that extended from Wisconsin to Florida. And we wouldn't be able to understand someone speaking English, nor would they understand us. Europeans wouldn't discover the New World for another 700 years. Regardless we will have long forgotten the SETI Institute and the signals they sent. We may be extinct, civilization may just be a memory, or we may be colonizing space. But nobody will be listening in any case.
  
  
• It's impossible to do a cost benefit analysis. Nobody can tell you the probability that these signal will be detected, or if they are, what the reaction of extraterrestrials will be. Is there a 1 in a million chance that ET will decide we're a threat and eliminate us? Is there a 1 in a million chance that ET will call off colonizing the Earth when they receive a signal from us? There is no way to determine this. ET could be just like us (which would be frightening) or so different that we don't even recognize each other as intelligent (which would be frightening).
  
  In a comparison risk analysis, suppose a 10km asteroid were going to pass through the Earth's atmosphere, igniting fires that would kill a million people. We could divert it, but there would be a 1% chance it would hit the earth destroying all life. Which choice do you make? There are ways to decide based on projected outcome and the probabilities. No such analysis can be done for METI.
  
  
• The future doesn't get a vote. How many people will live in the next 1200 years? We can't consult them. Proponents seem consoled by the idea that any bad outcome won't occur in our lifetimes. If a bad outcome were to occur, those living at the time might not be so consoled by the fact that it didn't happen to us.
  
  
• The signals that proponents claim we've already sent (TV, radio, Arecibo radar) are not nearly as likely to be detected as they claim. We couldn't even detect TV and radio signal at the nearest star with Arecibo. The Arecibo Planetary Radar is detectable at distances of thousands of light years, but doesn't repeatedly target the same spots on the sky. Someone receiving a single pulse is likely to discount it because it isn't repeatable.
  
  

I take it it's not OK to leave it as it is until Monday in it's crashed state then? If non of the remote stuff works?

I don't have any experience with database software so don't know if the following is of any help to speed-up the 'things' (and you probably know it all):

Eric i have a question which is probbably stupid but any way here goes .

....

So my question to you is this .

If it was the server that stuffed up and you are now replacing it with another system could you not just do what i did load what ever drivers you needed for the new server and just put the old drives in that and just continue on

If you don't mind me asking, what version of Informix do you use?

IDS 10.00, unfortunately.

And which Edition?
Some say e.g. "Resource limited to a single CPU core and 1GB of server memory"
http://en.wikipedia.org/wiki/IBM_Informix_Dynamic_Server

IDS 10.00, unfortunately.

Any Mileage in updating to V12?

If you don't mind me asking, what version of Informix do you use?

Thanks for the update Eric, I'll keep my fingers crossed that it's worked. I take it the data dump and reload would mean starting over?

Eric said:
Second, because of funding, Astronomy isn't top dog at Arecibo anymore, so Astronomers get a smaller fraction of the observing time.

I thought research in astronomy was the reason Arecibo was built.
I have a question. When the people running Arecibo aren't using it for astronomy, what are they using it for?

I hate to hear that we had to re-crunch several months' data because it "had a problem."

Thank you, Eric.

One more question: what's happening with Beta?

1. Bruno started hanging with a "stuck cpu" linux kernel message. I don't know what causes this sort of thing. Moving all the services except uploads to other machines seems to have solved the problem, so far. Next week we're planning to replace Bruno with a Sun X4540 that the Lab was removing from service.

2. Around the same time, the Astropulse assimilators started failing with a message "-603 Cannot close TEXT or BYTE value." Turns out we had run up against another informix limit. I'm resolving that, but it's looking like we are only 1/8th of the way done after 24 hours. Until it's done we won't be able to generate Astropulse work.

3. New Data. Finally, in the last few weeks, we've gotten some data from 2014 split and out the door. Not a lot, though. There are a few reasons why it took so long. First, the Arecibo itself and the ALFA receiver that we use for SETI@home was offline for much of 2014 (mostly January to June), so we don't have that much data. Second, because of funding, Astronomy isn't top dog at Arecibo anymore, so Astronomers get a smaller fraction of the observing time. And compounding it is that disks are bigger and we don't send a box until it's full (to save on shipping costs), so it takes longer to fill a box of disks. Which brings us to...

4. Old Data. We have been working on old data. It's not a "make work" thing. Most of the data we've been sending had a problem the first time around. Either part of the data was left unprocessed, or the results were questionable. In addition, all the old data that has been sent had not been processed with S@H v7, so there was no autocorrelation analysis done on it. We've still got big chunks of data that have never been processed with Astropulse to send out. We don't believe in making work for the sake of making work.

5. Will we run out of data? It depends upon what you mean by that. We may run out of SETI@home data taken by the current data recorder, although there is still plenty of Astropulse data to process. Jeff is prioritizing the GBT data splitter, so we hope to have that on line before too long. It will also be the starting point for the next thing, which will be to use SERENDIP VI as a data recorder. It should be capable of much higher data rates (GBps) than the current recorder, and therefore much higher bandwidths. It should also give us our first taste of the 327MHz Sky Survey data.

Hope that answers some of your questions.

No, but eventually driver issue with first version of ML (10.8.0) Updating OS X to 10.8.5 recommended, not only for GPU driver, but more to reduce security risc of unsolved OS bugs in that version.

Ok, I'll talk with Eric if we could exclude such hosts from stock distribution.

Currently the minimum OS version for MacOS ATI is 10.7.4. Are we suggesting that be increased to 10.8.5, or just that 10.8.0-10.8.4 be excluded?

As 10.8.0-10.8.4 were not in beta, my suggest (without volunteers doing further tests we can't be more precise) is to exclude 10.8.0-10.8.4

No, but eventually driver issue with first version of ML (10.8.0) Updating OS X to 10.8.5 recommended, not only for GPU driver, but more to reduce security risc of unsolved OS bugs in that version.

Okay, how do I stop the repeated "Notices" from firing in BOINC that lead to this political blog message? Seriously.

The comment link looks to be:

Comments - Protecting and Promoting the Open Internet

The proposal to abandon Net Neutrality on the internet in favor of a multi-tiered content-biased system is deeply flawed. It would:

1. create a system that inhibits technical innovation by allowing ISPs to choose which technologies their customers can access.
2. create a system that protects entrenched companies while penalizing the start-ups that have been the life blood of the internet.
3. limit access of non-profit organizations that cannot afford "fast-lane" fees.
4. penalize media companies that do not directly own cable or satellite access to consumers.

The Internet has flourished under the de facto common carrier ISPs held until recently. It is time for the FCC to declare that ISPs are Common Carriers and hold them to that status.

I volunteer to be the next Fred. Bring it.

Eric-I wasn't coming to you because you told me you aren't interested in any discussion or responsibility over the forums anymore-suddenly you are. I'm confused.

Thanks for the thoughts and the information-I do appreciate it

While I have not made a formal decision yet--Should I contact Legal Authorities, I am nearly positive they will want a name and a contact number for the person who oversees the forums.

Please allow me to question this. Escalating consequences I don't see other than I acknowledge he is clearly getting banned quicker.

rolling golden hills

So, if Intel were to support Core CPU/iGPU's on linux, somebody would eventually figure out that they can save thousands of dollars, and get more performance for their 1000-node supercomputer if they built it on Core. So, don't expect to see a linux Core OpenCL driver any time soon...unfortunately Intel will protect their interests on this one.

I downloaded but it says it is suspended because your device is busy with other apps. Not running anything other than what I usually have running.

Sorry, but I read that in my prev netbook's manual (Acer Aspire One). They definitely recommended full charge/discharge cycle when possible.

Does anybody know how much SETI / Boinc will drain your phone battery ??

I'm wondering about having them being on power 24/7, as far as I know it's not good for the battery?

considering the low-power -> low crunch rate of mobile phones, why make an ARM version to begin with? Is crunching on your mobile really going to contribute to the grand scale of SETI and other BOINC projects, or is it just going to drain your battery faster without making much of a difference at all?

Congratulations to this idea, unfortunately, appears after the start of the app only STARTING on the screen and over and over again
my smartphone is a motorola razr i ; with intel inside ;-)
Android is 4.1.2

When the RAM is Full, android stop World community grid application and nativeboinc looks for the file containing the results of the calculation, but it don't find this results file and cause computation error.

The HTC ONE has returned 10 tasks in a few minutes, all with "Computation error" :-(

I'm trying to create an account but the last part, "Please enter the words shown in the image", I don't see any image or anywhere to type an answer.

Using newest Firefox, IE 8, and Chrome.

Where in the android app does one create the account? Or, create a project? I'm having difficulty finding this area, I only see a place to enter a URL and a password, but it isn't working in any way.

Please let me know if and when an iOS version is developed. Thank you.

What a great Idea. But it will not verify my login information.

Eric, is it possible that the differences in credit rates for MB and AP cpu are due to different hardware populations? IE people with higher-end hardware choose not to run AP?

A question remains why with V6 that works? a simple coincidence?

Who's claiming this? Show me the code that achieves this.

You can't seriously be basing efficiency calculations on this can you ?

Note that unfortunately I've yet to receive any response from Eric or the Linux & Mac Developer community to my request for input into getting public beta happening for x41zc, nor to earlier enquiries supporting my research into GPU reliability, aimed at improving fault tolerance.

Wouldn't it be easier to simply release a version of S@H that has it's sensitivity cranked up to the limits of the sensitivity of Arecibo, rather than ratcheting it up every couple years?

Sometime ago Matt said that the run time the work units was going to be extended. I have noticed the average work unit on my 660 TI is running around 18 minutes was was this the intention with version 7 or was this a pleasant side-effect, are there still claims to pack more than one job into a task?

I have a question, too. How comes that AstroPulse is still on V6?

Maybe the admins could adjust something for to prevent this?

Could be a bad/overheating card or bad driver. My bigger concern is why the daily quotas are being reduced when the invalid results are found. That needs to be fixed.

Please do Not 'fix' this.
Computers that spit invalid results have to be punished somehow.
Else they will do that for 1000s of tasks per day.

The only 'red' is from ClamAV - PUA.Win32.Packer.UpxProtector

When i checked last night i couldnt get to this site, now i cant get any work units,only units running are on my gpu.

Eric said he'd post some details on the differences with the new app back on Thursday. I guess he didn't get around to doing it

Only errors: hostid=6598140.

What is here the problem?

Resident Shield in AVG 2012 identifies boinc.exe as a virus. I have seen it only on one computer with 2012 as of yet. Log follows.

I have Trend Virus scan the best there is!!

Same problem with trendmicro Fake Antivirus (FakeAV) Removal Tool.

14:37:09 (23461): No heartbeat from client for 30 sec - exiting

I think I will stick with these versions and see if I can work out this heartbeat issue...

Any active developers out there that can provide any guidance?

I managed to run it manually in the slot with GDB. Error:

Starting program: /var/lib/boinc/projects/setiathome.berkeley.edu/setiathome_enhanced

I'd far prefer to see the establishment of an endowment fund that would fund the post for an extended period (minimum five years), or in perpetuity from investment income.

If such a biographer is ever assigned to Eric, I shall attend every interview!!!

Not sure where to post this problem:

I'm not receiving tasks?
I'm running 7.0.28 (x86) Am I doing something wrong?

• The surface of the Earth is warming, primarily due to increases in carbon dioxide in the atmosphere prompted by human use of fossil fuels.
  
  
• Natural gas is the least expensive means of generating gigawatts of electrical power.
  
  
• Nuclear energy is the safest way to generate gigawatts of electrical power.

So are you annoyed? I admit it, I did try to go out of my way to find facts that would annoy people. These aren't even controversial facts. I've expanded the error bounds to the 3-sigma level. None of these even approaches the "OJ is guilty" or "tax cuts/increases have a predictable effect on the economy" level of uncertainty. Even though these are facts, many of them are facts that get used or denied for political purposes. And because it's an election year in the U.S.A., we tend to assume that any statement is a political statement. Every fact is a fact with a hidden agenda. And most are beside the point.

Politics are so polarized that even admitting to a fact is assumed to be a capitulation to the entire agenda of a political party. The alternative is denial of the facts, which is not something I'd recommend. Can't we agree on the facts first, and then talk about what, if anything, should be done about them?

The final fact is just there to put it all into perspective.

Do the multiple workunits use some same resource of the GPU or interfere in some other way?

My company has upgraded some research hardware and has given me a Tesla C1060 unit. I was wondering if I can use it to process SETI@home and Eistein@home data. Any thoughts?

If we're already using the Open CL from the optimizers, should we stick with this?
