Presumably, this would also filter out multi-planet systems, sending messages between their planets? The chirp rates would differ for each planet in the system.

So, in conclusion, have the recent code changes resulted in a system that's more efficient and less error-prone?
Is Nebula now ready for routine use, and can you estimate on how long it will take to process all the SETI@home result files?
Many thanks for all your hard work on this.

Agreed. Politics and trolling should not be appearing in a SETI News thread.
This is the kind of information we ought to be focussing on in SETI News:

Are there any plans to include Optical SETI data with the pixel information?
It would be great to have a very broad spectrum associated with each sky coordinate pixel. Obviously, a pixel would become very interesting if it scored highly for SETI, SETENDIP and OSETI.

Post:
What data throughput are you achieving now? In a separate thread you talked about scoring 1 million pixels, but it sounded like the processing rate was slower than desired.
Any estimates on how long it now takes to process a fixed number of results and whether further optimisation is needed or being implemented?

Post:
Presumably, the only way to demonstrate that this is really RFI, is to check if the same drifting signal was detected simultaneously in some of the other 6 beams?

Any government would probably jump at the chance to announce the first discovery of an alien civilisation.
1) imagine the bragging rights they'd get from that
2) it would distract attention from all the geopolitical mess that humans have got themselves into

Another strange dip in brightness can be seen in the B-filter data on May 23rd. However, it's perhaps worth noting that all of these unexplained dips were recorded by the same observer (PXR).

11) Message boards : SETI@home Science : KIC 8462852 dimming events (Message 1787057)
Posted 12 May 2016 by Profile Jon Golding
Post:
Here's the plot showing the dip in brightness in the context of the (usually) steady brightness of around 11.8 - 11.9 mag.
I've taken the raw data from https://www.aavso.org/apps/webobs/results/?star=KIC+8462852&page=21 and made a plot of the dimming event. The entire dimming event lasts around 2 hr and is made up of a series of rapid dips in brightness. This would appear to fit with a cluster of objects rapidly moving across the face of the star (comets?)

Wow! That's a huge reduction in brightness. Even bigger than the largest 20% dip reported (https://arxiv.org/abs/1509.03622)

Posted 9 May 2016 by Profile Jon Golding
Post:
Seems that the series of observations showing a possible transit were all recorded by the same observer, so the results could be explained by a technical problem or local atmospheric effect that day. Going back to the original paper on KIC 8462852, some of those dimming events happened in clusters, so there may be more along anytime soon now. Hopefully someone can get a spectrum of the star during a dimming event and that might yield some clues as to what (or who!) is doing this.

Seems like there was a recent dimming of KIC 8462852 (Tabby's star), as monitored by the American Association of Variable Star Observers. https://www.aavso.org/lcg
Is this star planned to be included in the Breakthrough targeted search when Parkes telescope data becomes available?

Post:
Great to read that up to one third of the money ($33M) will be to hire new postgrad students and science professionals. This should certainly speed up development of new hardware and optimised NTPCKR algorithms to search through the mass of data already acquired (and yet to be acquired).
Also great to see that we'll be getting data from Southern skies via Parkes telescope.

Post:
@Eric. This is a big ask, I know, but how about making a slidecast of the talk you wanted to give, e.g. for a full 45 mins, and posting it on the SETI website (and YouTube)? Not only would it give everyone an update on what's happening in the various SETI searches, it would form a focus for discussion. Several of the people running SETI@Home are computing/signal processing experts and the discussions could lead to breakthrough ideas to improve the sensitivity or efficiency of searches.

The Astropulse data that Eric described in his talk are very interesting. Several hundred short burst signals have been detected, all within the galactic plane, and several of which were seen on more than one occasion (although not repeated in a one-off dedicated search). At the very least, these could be new astronomical objects, and at best they might be SETI communications. Could a grant be written to get funding to study these objects in greater detail? - with some of the funds being used for hardware, or a programmer, that could benefit SETI?

This was the first time I'd seen these data presented and it would be great to hear a little more about this from Eric sometime - perhaps a short summary post in one of these threads?

Post:
Somewhere near the beginning of this thread, a suggestion was made to start a funding drive to get a dedicated programmer to work on the Nitpicker. Most universities will provide matched funding for specific projects, so SETIzens might only have to come up with half the funding. This programming work could likely be done either by a good PhD student within 3 years, or by an excellent post-doc or specialist programmer on a 1 year contract.
It would first be essential to have an update from the staff on the status of the Nitpicker and their ideas on how to get it running again, and whether a dedicated programmer is what's required, or if they have all of that in-hand.
