Now accepting donations of gridcoin.

SETI@Home News - Wed, 2017-12-13 18:41
Because of several requests, I've resurrected the idea that we could take donation in gridcoin, a cryptocurrency you can earn by participating in volunteer computing projects.

Our gridcoin address is now listed on our donation page.

Special Fundraiser for Parkes Data Store and GPU development system

SETI@Home News - Thu, 2017-12-07 19:15
Thanks to our collaboration with Breakthrough Listen and their international colleagues, we will soon have the ability to access data recorded at the Parkes Radio Telescope in Australia. For the first time, this will give us full-sky coverage, including the southern hemisphere, in our search for ET. However, due to the enormous amount of data that the 13-beam receiver at Parkes can generate, we will require extra hardware to store and distribute it. We need your help to purchase this.

Thanks to some special offers, one from the Hanson family in memory of Robert W. & Mary P. Hanson, one from Richard Haselgrove in memory of his mother, Jenifer Leech, and one from Mr. Kevvy, we have the possibility to match donations which will allow us to purchase the Parkes Data store server (~$34K) and the GPU development systems (~$10K) we will need for the coming year. For every dollar you donate in this special fund raiser, Mr. Kevvy will match it, the Hanson Family will match it with two, and Richard Haselgrove will match it with two more. That means for every dollar you donate we'll get six dollars towards the purchase of these servers!

Because this is a special fundraiser we'll have special notation on your account page and on the forums. The 12TB disk drives in the Parkes Data Store cost $450. One sixth of that is $75. So, a donation of $75 or more gets you a disk drive icon. The GPUs in the GPU development machine that we will be using for our recording systems at future telescopes are $1500 each, so a donation of $250 or more will get you a GPU icon. And as always, any donation of $10 or more will get you a green star.

But in the end, it's not about the icons: it's about getting the data and making a discovery for the ages. Your help, whether by crunching data or by donating, is always appreciated.

Splitters off, again :(

SETI@Home News - Wed, 2017-12-06 05:39
I had to turn the splitters off, again. I underestimated the rate at which we were creating work (damn moveable decimal points!). I thought we could go without adding more space to the database until we had time (tomorrow morning) to delete the old database spaces.

I was wrong, we really zoomed through the files on disk, and we ran out of space. Deleting database spaces is dangerous, so I really want Jeff to check the command script before it gets run. That won't happen until morning. But once it does we'll be back in operation.

Hopefully most SETIzens won't even notice this short absence of work.

Berkeley SETI Research Center undergraduate research internships, summer 2018

SETI@Home News - Tue, 2017-12-05 01:23
Applications are invited for 10-week paid undergraduate research internships at Berkeley SETI Research Center for summer 2018. BSRC is a
world-leader in the search for extraterrestrial intelligence – the quest for a scientific answer to one of humanity’s oldest questions: Are we
alone in the Universe? Housed in the Astronomy Department at the University of California, Berkeley, the team at BSRC leads the science
program for the $100-million Breakthrough Listen project. Our scientists and engineers are pioneers in the development of software,
instrumentation, and science strategy for the search for intelligent life on other worlds. We have access to substantial amounts of time on
the planet’s largest telescopes, connections to leading players in industry, and we’re based in one of the world’s premiere astronomy
research institutions. We’re also psyched that we get to wake up each day and hunt for aliens.

Current sophomore, junior, and senior undergraduates (including non-US citizens) studying at a degree-granting institution in the US are eligible to
apply. Around 5 - 7 positions will be available. A stipend of $20 / hr (up to a maximum of $8000) will be provided. Details and links to the application form are at https://seti.berkeley.edu/Internship.html

We're generating work again.

SETI@Home News - Sat, 2017-12-02 07:19
It took a bit longer than I thought it would, but we're back online. It'll probably be a few days before we have a full ready-to-send queue.

Now we can get back to finding ET.

No work. Database issues.

SETI@Home News - Wed, 2017-11-29 21:41
At first I thought the restart on Tuesday had solved our database problems. I guess I was wrong. It only fixed some of them.

We've hit yet another hidden limit in our Informix science database. The good news is that we know how to fix this one. The bad news is it will take a little while.

We don't have to wait for the full fix before starting to split again, but the point at which we can split will probably be sometime tomorrow. Until then, we only have a few re-dos and a little bit of astropulse to do.

Richard Lubrich has passed away.

SETI@Home News - Wed, 2017-11-29 01:43
Long time setizen, Richard Lubrich (Dr. C.E.T.I., aka Dr. SETI, aka nobody) passed away today. Richard was a fixture on the forums from our earliest days. He was a great friend to SETI@home and will be greatly missed.

Database slowness

SETI@Home News - Sat, 2017-11-11 00:09
We're having some as yet unexplained slowness with the our BOINC database. There don't seem to be any hardware issues. Temperatures are running normal and all the drives seem good. Yet for some reason the query that fills the "ready to send" queue is running about 10 times slower than it normally does.

Until I get it fixed, it means that on average we're sending out 3 workunits a second rather than 30+.

I'll let you know when I've got it figured out.

SETI@home 2017 fundraising drive has begun.

SETI@Home News - Fri, 2017-11-03 17:29
We've started our annual fundraising drive to help raise the money we need to keep SETI@home running and expand it to new telescopes. Your computers provide us with the power to analyze this data, but your donations are an important part of keeping us operating.

If you haven't yet received your fundraising letter, you can preview it here. You can donate at https://setiathome.berkeley.edu/sah_donate.php.

Thanks for keeping SETI@home going!

BSRC Student Travel Fundraiser

SETI@Home News - Mon, 2017-10-02 18:10
Berkeley SETI Research Center is holding a fundraiser to raise $7000 to send our student interns to conferences to present their work.

We’ve been working with some great students at Berkeley SETI, and we’re optimistic that some of them will become the scientists and engineers who lead the field in future and maybe even find the signal we’re searching for. In the meantime they have been doing amazing work and we’d like to send them to academic conferences to present their results, and for their own professional development. If you would like to help with this effort, we are running a crowdfunding campaign at https://crowdfund.berkeley.edu/SETItravel - every donation counts! We also have some fun perks including the chance to ask questions to members of the Berkeley SETI team, and to attend a party in our lab.

Although this does not directly benefit SETI@home (our annual fundraiser will start in a couple weeks), it's a worthy cause. I'll be contributing!

Arecibo Status

SETI@Home News - Thu, 2017-09-21 17:11
I've been asked by several people to post a status update on the situation at Arecibo following hurricane Maria's passage.

Unfortunately, at this point we haven't gotten any news. The last information we have is from a couple hours prior to when the eye passed Arecibo. That report said all the employees were accounted for and in sheltered buildings.

Since then we've had no news. That's understandable. With power out on the whole island, electronics communications aren't going to be possible for some time. Heavy rains are still expected today, so I'm sure that the primary concern is still keeping everyone safe. Assessment of any damage will take time.

Let's hope that everyone is safe, that their homes are intact, and that any damage can be repaired quickly.

Data from "Tabby's Star" is flowing.

SETI@Home News - Thu, 2017-09-07 16:36
For those who didn't recognize the name KIC8462852 in their work unit names, this data comes from GBT observations of Tabby's Star (aka Boyajian's Star, aka WTF-0001, aka the Weirdest star in the galaxy). This is not yet the full data set, which lives at Penn State, it's some test on-target/off-target observations that we're checking out.

You might also notice another change. We've doubled the size of our work units which will reduce our quantization noise by 34%, and, depending on the strength of other noise sources, could give us as much as double that as a sensitivity increase.
