Yes, we at Seti@home are crunching data provided by the Breakthrough Listen telescope at Green Bank. But Seti@home is a standalone project with its own objective. Breakthrough Listen is a standalone project with its own objectives. Some personnel is shared among the two projects but BL obtained Matt Lebofsky from SAH and is no longer affiliated with SAH and works only for BL. Matt was the person that used to keep up abreast of the server status with frequent technical posts. Jeff Cobb still makes an appearance rarely here at SAH and mostly works for BL. The only personnel still 100% dedicated to SAH is Eric Korpela and David Anderson. David mostly works on the BOINC software.

Again, BL does not produce or publish any of its own distributed computing programs. They just have been gracious to share their data with Seti@home.

Sorry I've been MIA for most of the past few years but I heard I was mentioned by name around here so I'd figure I'd clarify/correct some bits of this (largely accurate) summary.

1. Jeff works entirely on S@h. I'm the only person on the S@h team that moved to BL, though I still help S@h from time to time given the parts that cross over.
2. I'll confirm: SETI@home gets some (maybe most these days) of its data from the Breakthrough Listen data collection pipelines. Otherwise, despite this and being collaborative colleagues in the same field, these are two separate projects. That said, Jeff and I do have adjacent desks in the same cubicle.
3. While not using distributed computing/BOINC like SETI@home, Breakthrough Listen aims to make all data products public, along with analysis tools, so individuals/groups could come up with their own SETI searches on existing data. Recently there was some press about making the first Petabyte of Breakthrough Listen data public: https://breakthroughinitiatives.org/news/25
4. I miss writing up regular reports but I'm both very busy and also still haven't figured out the most appropriate forum to write casual blurbs like the old days.

Feels good to chime in on this forum again.

Wrong, I advertise them on my screensavers. Google knows the price of advertising.

Again, I am not arguing that we have nothing to do with BL. As I stated, we do get some of their data. Not all of it. And we did not have any involvement with their recent papers. They crunched their own data on their own servers with their own applications.

You do not contact any of their hardware with your hardware. You do not run any of their application software. You run Seti@home software and communicate only with Seti@home servers. Other than getting some data from their sources, you have no direct involvement with Breakthrough Listen.

On the upper left of my screensaver i see the following label: Seti@home/Breakthrough!
Two "independent" projects?

On my screensaver when playing Green Bank data I see the SETI@home logo left and the capital words Breakthrough Listen at right. I am running stock SETI apps. The Green Bank data are from August 10 2018.

I think both Breakthrough Listen and Seti@Home.
https://en.wikipedia.org/wiki/Breakthrough_Listen

The project uses radio wave observations from the Green Bank Observatory and the Parkes Observatory, and visible light observations from the Automated Planet Finder.[8] Targets for the project include one million nearby stars and the centers of 100 galaxies. All data generated from the project are available to the public, and SETI@Home is used for some of the data analysis.

Understanding what the BLC name means like.

I am not aware of any BOINC distributed computing project run by Breakthrough Listen. You are just running the standard BOINC Setiathome project which has a screensaver for the standard cpu tasks. I don't even know what the Breakthrough Listen logo looks like.

Seti@home and Breakthrough Listen are independent and not related projects. That also would be Jeff Cobb not John. Arecibo Observatory is not targetable or steerable so would not be in the observing plans of Breakthrough Listen.

I found a link to two BL articles on theregister.co.uk. Many of the authors are well known, including Matt Lebofsky and John Cobb, but SETI@home is never mentioned. I wrote a short comment saying that I am crunching data from Green Bank but not data from Parkes. Evidently BL gets data from Parkes. Also Arecibo is never mentioned.

Breakthrough Listen Releases 1 Million Gigabytes of Data from Its Search for E.T. | Space

May 18th, 2019 - /r/GreatFilter: The Great Filter is the most urgent question Mankind has ever faced. It's the solution to the Fermi Paradox. The Great Filter is Robin Hanson's hypothesis there are no other technological civilizations (not even on Earth) because they die before they colonize a galaxy. The mission of r/GreatFilter is to raise awareness of the value and fragility of life, and thus the importance of peaceful colonization of space beyond Earth, one rock at a time.

Raw data, spectrograms (dynamic spectra), filterbanks, waterfall data... All about the data formats Breakthrough Listen and Berkeley SETI want to make openly available to the scientific community. Accessible and enlightening article, but can rapidly get technical as soon as you scratch the surface !

2019.02.02 - Open data by Steve Croft

Breakthrough Listen generates huge amounts of data, particularly from the two main radio telescopes where we're doing routine observations, Green Bank and Parkes (and we'll be generating even more once we begin routine observations with MeerKAT). Part of our mission is to make as much of that data as possible publicly accessible, and to that end we have a substantial amount of data already in the Breakthrough Listen Open Data Archive, with much more to come in the near future. (...) We're hopeful that releasing raw data in open format will encourage more collaboration between SETI researchers and experts in the tech and RF industries, and that we'll be able to work together on algorithms to identify a wide range of signals both in our data, and in similar data from other sources, in search of that elusive signal from a technological civilization beyond Earth. http://seti.berkeley.edu:8000/open-data/ http://breakthroughinitiatives.org/opendatasearch

I like this: "Do your best, but remember and accept that you can’t fix arrogant ignorance." because it so fits in politics today.

I am crunching Arecibo data from January 31. Amazing!

Old enough to be alive when Arecibo datatapes used to be Fed-exed to Berkeley : Check.

My opinion on all this ? For sanity's sake, politicians should be restricted to the word gazillions for anything beyond a million

They can always play the game :-)) gazillionaire
