[11:00am] jrseti_: Hello all! It is 11am California time
[11:00am] sigblips: Good afternoon.
[11:01am] jrseti_: Leash - are you on-line?
[11:01am] leash: Yes. Sorry. I'm here.
[11:02am] Jill joined the chat room.
[11:02am] jrseti_: Hello Jill
[11:02am] Jill: hi Jon
[11:03am] jrseti_: Agenda: 1) Website issues 2) Google+
[11:03am] sigblips: 3) Massive Amazon AWS EC2 reboot status.
[11:03am] jrseti_: 4) Webcam pics
[11:03am] sigblips: 5) Status of the October 51.2 kHz artifacts / dropped packets / network issue?
[11:04am] sigblips: 6) Any mention of setiQuest has disappeared from the main http://seti.org page.

[11:05am] jrseti_: 1) Website - How has the spam been/ Not so much this week, I think.
[11:05am] jrseti_: It goes in waves
[11:06am] sigblips: Yup, not much forum spam this past week.
[11:06am] jrseti_: What about http://setiquest.org/forum/topic/hi-all#comment-2904
[11:06am] gliese581c: Title: hi all | setiQuest (at setiquest.org)
[11:07am] jrseti_: I guess that is OK
[11:07am] jrseti_: AAny ideas for a new poll question?
[11:08am] jrseti_: I need suggestions.
[11:08am] sigblips: Heavens is talking about Time Travel and Morlocks in a different thread with Dave Robinson. Not spam.
[11:10am] jrseti_: Well - if anyone comes up with a Poll question idea - email me
[11:10am] Jill: i'm half listening in on a webcast that is supposed to happen soon - Paul Allen announcing StratoLaunch Systems - any orbit, any time.

[11:13am] jrseti_: People can then be ferried to the Chinese space station :)
[11:13am] sigblips: Personally, I'm waiting for the Space Elevator. (: Does anyone know the status of that? Is it still a materials problem?
[11:14am] Jill: maybe a poll question about hman space flight and private funding?
[11:14am] jrseti_: Jill: good idea
[11:15am] jrseti_: 2) Google+. Leash - what do you know about it?
[11:16am] Jill: Paul's craft looks uncomfortably like the Spruce Goose - hope he flies more than that did.
[11:16am] Jill: Jon - don't understand your question about Leash
[11:17am] jrseti_: Leash was going to help us with social media issues - I think she was going to research Google+ for us, how to use it properly for our site
[11:18am] jrseti_: I briefly spoke with Ly, he doesn't know yet how to use google+ for seti.org
[11:19am] leash: I'm still not sure what you want to accomplish with that...
[11:20am] jrseti_: Me neither - but the question keeps coming up. How do we use google+ for setiquest?
[11:21am] sigblips: Google+ is a lot like Facebook. So a similar strategy would seem appropriate.
[11:21am] leash: I feel like google+ is dying slowly. I've seen a lot of advertisment for it, and it seems that facebook fans are remaining loyal.
[11:21am] jrseti_: I've read the info about it on the google site. I really do not understand. There is a way to use it to promote a site, and create community, like Facebook. it would be good for a Google employee to come talk to us, set us straight!
[11:22am] jrseti_: Is Google+ dying slowly? I never heard that.
[11:23am] leash: MY statement is pretty speculative. I don't see anyone I'm networked with updating anymore. I see google putting ads for it everywhere. I just think that it's not caught on yet.
[11:24am] Jill: haven't heard about its death, but haven't seen it take off either
[11:24am] jrseti_: I personally don't know anyone using it. My kids don't
[11:24am] jrseti_: But, that is not a good measure
[11:25am] jrseti_: But, we need to get educated about Google+. Leash, could you do some poking around and see if you can learn how to use Google_ to promote a site?
[11:25am] leash: Absolutely.
[11:26am] jrseti_: Great, that would really be helpsul
[11:26am] jrseti_: helpful
[11:26am] jrseti_: 3) Massive Amazon AWS EC2 reboot status
[11:26am] jrseti_: Sigblips?
[11:26am] sigblips: Amazon has scheduled a forced reboot for the us-east region. The rumor is that it's to fix a Xen VM vulnerability.
[11:27am] jrseti_: There was some work involved for you, right?
[11:27am] sigblips: The setiQuest EC2 machines never were configured to be rebooted. Some had 500+ days of uptime.
[11:28am] sigblips: Every instance was manually rebooted and services started by hand. All is OK.
[11:28am] jrseti_: I wonder what the world record is for a server uptime?
[11:30am] sigblips: Gerry's machine did an automatic Fedora package update after the reboot and froze up, couldn't ssh in, it needed some extra work. It's OK now.
[11:30am] jrseti_: Thanks!
[11:31am] sigblips: I don't know the server uptime record but it is > 1000 days and I'm sure there is a website about it. Linux people take their uptime very seriously.
[11:31am] jrseti_: http://en.wikipedia.org/wiki/Uptime
[11:31am] gliese581c: Title: Uptime - Wikipedia, the free encyclopedia (at en.wikipedia.org)
[11:31am] jrseti_: Novell reported 6 years for one server
[11:32am] jrseti_: So, 500 days is a good one
[11:34am] sigblips: The problem with AWS and great uptime is that people don't plan for failure or a reboot.
[11:34am] jrseti_: That is a good lesson
[11:35am] jrseti_: 4) Webcam pics. I am working on a process to push out to our server periodic pictures from the 2 webcams at the ATA.
[11:35am] jrseti_: Yesterday we were informed the data rate out of the ATA has dropped to 3Mbps
[11:36am] jrseti_: Os, any pushing out of data will have to be minimal for now.
[11:36am] jrseti_: There are plans to raise the data rate after the first of the year
[11:36am] sigblips: Has anyone done a http://www.speedtest.net/ on the line yet?

[11:37am] jrseti_: That is a good idea. Maybe next time I am there
[11:39am] jrseti_: 5) Status of the October 51.2 kHz artifacts / dropped packets / network issue?
[11:40am] jrseti_: Jill, what was the outcome of this? Was it a bad cable connection?
[11:41am] Jill: Billy Barott thinks he understands this - i'm not sure i do.
[11:42am] jrseti_: So...I don't know!
[11:44am] jrseti_: 6) Any mention of setiQuest has disappeared from the main http://seti.org/ page.
[11:44am] gliese581c: Title: SETI Institute (at seti.org)
[11:44am] sigblips: Was it a hardware, a Walshing, or a software problem? Is it fixed?
[11:46am] jrseti_: Sigblips: I do remember Billy saying the problem he had earlier this year has been fixed. It was software. Also, I know it was not Walshing, or at least it is not thought to be related to that. I'll have to ask Ken and/or Billy
[11:46am] jrseti_: "SETI Search Resumes at Allen Telescope Array, Targeting New Planets" is on the main seti.org page.

[11:50am] sigblips: If setiQuest isn't promoted then people won't know about it and they won't join.
[11:50am] jrseti_: Don't know what to do about this. We need a setiQuest police force within SETI
[11:51am] jrseti_: I'll talk to the webmaster and a few other people about this
[11:51am] sigblips: The people in charge of the SETI Institute website and twitter feed need to be recruited!
[11:52am] Jill: that's a tension i'm struggling with. when we say 'support us' or 'join us' do we mean contribute $$ or skills. right now i'm under huge pressure to bring in hard cash, so the article mentioned setistars.org and thanked previous contributors
[11:54am] jrseti_: Plus, there are a lot of people involved. You feel like you are trying to herd cats: http://www.newsrealblog.com/wp-content/uploads/2011/04/Herding-Cats.jpg

[12:00pm] jrseti_: So sad about Grunt
[12:01pm] jrseti_: Well, it is past the hour. Thanks all!
[12:01pm] sigblips: Imagine walking down a beach and stumbling across some radioactive space junk?
[12:02pm] jrseti_: They were smart to leave it alone.
[12:03pm] jrseti_: bye!
[12:03pm] sigblips: See ya later.

5) Status of the October 51.2 kHz artifacts / dropped packets /

After much moving of cables and ports on the switch, there were no consistent results.
Ken noticed that the second power supply for the switch was not connected.
When the second power supply was plugged in, the missed packets and
artifacts disappeared.

Hello Janebird, Could the

Hello Janebird,

Could the second power supply have been unplugged prior to the April hibernation? Or is it a recent problem?

The reason I ask is because I've seen lot's of zeros in the setiQuest data (http://setiquest.org/wiki/index.php/SetiQuest_Data_Links). I'm wondering if it could be related?

Missed packets

I misspoke that the missed packets have disappeared. We do get occasional missed packets, but not the huge numbers we were seeing when the power supply was not connected. The missed packets are filled with zeroes.
The unplugged power supply was a recent problem that occurred when the equipment was moved back to Hat Creek Observatory. So much to do and not enough time.
