New SETI Perspectives article
Richard M Lawn has posted another interesting article to the SETI Perspectives forum. This one is about the mysteries of Fast Radio Burst (aka FRBs), possibly some of the most distant explosions ever seen.

We're back up.
Hopefully there won't be any further problem.

Our attempt to upgrade the memory on Oscar (the BOINC database machine) and Carolyn (the replica database) took a bit of DIMM swapping to find pairs of DIMMs that worked. Carolyn is still short two DIMMs (32 GB), but we didn't want to extend the outage any further to try to get it up to the full 192 GB.

We might try to max out Carolyn during the outage next week.

[edit]And as is usual after a long outage, we've got a large number of hosts out there starving for work. It'll take a little while before "no work" messages start to get less frequent.[/edit]

Download server glitch
We had a problem with one of our download servers that was slowing down downloads and slowing down work generation. We've fixed the problem, but there are lots of people out there trying to download. It'll probably be a while before our downloads aren't swamped with requests.

Work ready to send has started trending back up, so we shouldn't end up with a work shortage.

New forum, and a new contributor.
We have added a new forum called SETI Perspectives that will showcase thoughts on SETI and related topics from people not directly connected with the Berkeley SETI group. Richard Lawn, Ph.D is our first contributor with an article about 'Oumuamua, the first object we've seen that convincingly originates from outside from outside the solar system. We hope have a long collaboration with Richard. Please welcome him into the SETI@home family.

Setizen Gordon Lowe has passed away
I'm sad to report that we've lost another long time SETI@home volunteer and moderator Gordon MacKenzie Lowe. A remembrance thread has been started here.

Gordon will be greatly missed.
