Today's topic can be:

  1. Lou from SETILive cannot be onthe chat today.

[11:00am] jrseti_: Hello

[11:00am] jrseti_: Hello ALL
[11:00am] jrseti_: See http://setiquest.org/forum/topic/community-meeting-2012-10-30
[11:00am] jrseti_: Sorry - Lou from SETILive can not make it.
[11:01am] sigblips: Hello. Here are my topics for today:
[11:01am] sigblips: 3) spam update and forum changes.
[11:02am] sigblips: 4) the setiQuest meetup group needs a new organizer or it will be deleted.
[11:03am] sigblips: 5) Kickstarter 64-core supercomputer funding question. http://setiquest.org/forum/topic/99-arm-supercomputer
[11:03am] sigblips: That's it for me.
[11:03am] jrseti_: great. 1) SETILive - Lou is still working on it! I don't have an update
[11:04am] jrseti_: 2) We have a volunteer jay Freeman and he is going to try to run the SonATA distro. Maybe in the next couple of weeks
[11:04am] jrseti_: 3) Has there been much spam?
[11:04am] sigblips: I tried the SETI Live beta demo and I sent Lou some feedback. Nice minor changes but it doesn't fix any of the big issues.
[11:06am] jrseti_: Yes - he has to fix most of those bugs.
[11:07am] sigblips: Have you noticed all of the recent Zooniverse product launches?
[11:07am] jrseti_: Yes - SETILive not mentioned
[11:07am] jrseti_: Which is a good thing. I don't want anyone to use it till it is all working
[11:08am] sigblips: The have been working with so many other people on so many different projects it's no surprise that SETI Live has been neglected.
[11:09am] jrseti_: I really have to concept of their internal organization.
[11:10am] sigblips: You mean "no concept?" I think they have far more on their plate than they can handle.
[11:10am] jrseti_: But - it appears the SonATA/ATA side of the SETILive process is all complete.
[11:11am] jrseti_: I mean - I only talk to Lou, I never hear about any of their other projects directly from them.
[11:11am] sigblips: Good job on your part. What are you working on now?
[11:13am] jrseti_: I'm working on internal projects. One with the correlator. I am also trying to teach myself CUDA
[11:13am] dk3232 joined the chat room.
[11:13am] sigblips: That sounds interesting.
[11:13am] jrseti_: A company "Silicon Wolves" gave me access to their Tesla 2075C GPU on their server.
[11:13am] dk3232: hello
[11:13am] jrseti_: hello
[11:14am] dk3232: what has been going on?
[11:14am] sigblips: Hello dk3232, here is a link to what you've missed. http://irc.sigblips.com/setiQuest/2012/setiquest.10-30-2012.log
[11:14am] jrseti_: I'd like to get my mind around how to get the correlator to run in a GPU
[11:14am] sigblips: I thought Silicon Wolves went out of business?
[11:15am] jrseti_: They did - the guy moved to New York and set up shop again.
[11:15am] sigblips: I thought they moved from San Diego to Alaska?
[11:15am] dk3232: what ever happened to that 64 core open source system?
[11:16am] sigblips: That's on our topic list today. We will get to that in a sec.
[11:16am] jrseti_: I admit - it is confusing. They used to be connected with people in Alaska. I think that fell through. They moved to New York.
[11:17am] jrseti_: Anyway - I have a really good book called "CUDA by Example". I've been able to run the CUDA examples and also run some benchmarks that Berkeley has.
[11:18am] jrseti_: The CUDA environment is really easy to get up and running. The hard part is getting programs to run well within the GPU mindset.
[11:18am] sigblips: What are your thoughts about PCI bandwidth getting data to and from the GPU being a major limiting bottleneck?
[11:18am] jrseti_: The newer MacBooks have a NVidia GPU in them. Mine is too old.
[11:19am] sigblips: Last years Macs had ATI GPUs, those aren't compatible with CUDA.
[11:20am] jrseti_: I don't think the bandwidth will be a show-stopper. Multiple GPUs will have to be used - for sure.
[11:21am] jrseti_: FYI: Sorry - i have to leave at 11:30.
[11:21am] jrseti_: Unavoidable
[11:21am] sigblips: OK let me mention last weeks spam and the forum changes.
[11:21am] jrseti_: ok
[11:23am] sigblips: Last week I woke up to the horror of 82 spam messages in the forum. It took me an hour to clean up that mess. That was more time that it took the spammer to create them! You can read about it in last weeks transcript. http://setiquest.org/forum/topic/community-meeting-2012-10-23
[11:24am] sigblips: I was sick and tired wasting my time with all the spam so I put the setiQuest forum into moderated mode. http://setiquest.org/forum/topic/moderation-mode
[11:25am] jrseti_: I assume that worked?
[11:25am] sigblips: It was a bit of work at first. It was like a leaky bucket. I'd plug one hole and the spam would start leaking out of a new hole.
[11:26am] sigblips: After a bit of work I think it is all patched up. It is actually a huge improvement. I created a new "trusted user" mode and the miserable CAPTCHAs are gone. Avinash should of done this years ago.
[11:27am] jrseti_: great!
[11:27am] yiyus left the chat room. (Ping timeout: 260 seconds)
[11:27am] sigblips: It is a little too soon to declare victory but I'm fairly certain this is Game Over for the spammers.
[11:28am] sigblips: Next topic. The setiQuest meetup group is going to be deleted if no one steps up a the organizer. 10 days are left. http://www.meetup.com/setiQuest/
[11:29am] sigblips: Did you cancel your leadership role by accident?
[11:29am] jrseti_: We never use it. At first we thought we might - but it costs $150 a year - I think
[11:29am] jrseti_: Should I renew it just in case?
[11:29am] jrseti_: No, I did not cancel my role
[11:29am] sigblips: They charge for it? That is ridiculous. No, delete it.
[11:29am] jrseti_: Must have canceled automatically
[11:30am] jrseti_: OK, I'll delete it then.
[11:30am] sigblips: Don't worry. The links says it will automatically be deleted in 10 days.
[11:31am] jrseti_: OK
[11:31am] jrseti_: Sorry - I need to go...
[11:31am] jrseti_: Thanks, Sigblips!
[11:31am] sigblips: OK, bye.
[11:31am] jrseti_ left the chat room. (Remote host closed the connection)
[11:31am] sigblips: Here we go dk3232.
[11:31am] sigblips: 5) Kickstarter 64-core supercomputer funding question. http://setiquest.org/forum/topic/99-arm-supercomputer
[11:32am] sigblips: They exceeded their funding by $150K so the 16-core board is a go. They still need about $2M for the 64-core version.
[11:34am] dk3232: cool
[11:34am] dk3232: 16 core is awesome
[11:34am] sigblips: What are your thoughts on developing SETI algorithms on a 64-core chip?
[11:34am] dk3232: i am no sure yet i have never owned a computer that had more than one core
[11:35am] sigblips: It seems like a great educational board. Unfortunately I don't think the SETI Institute has any plans for using it. Maybe they will evaluate it?
[11:35am] dk3232: do you know when this 16 core will come out?
[11:35am] sigblips: Parallel programming is tricky.
[11:36am] sigblips: They say it should be out spring 2013.
[11:37am] sigblips: The 16-core board/chip was $99 on Kickstarter. I have no idea if or how much they will sell it for to the public.
[11:38am] sigblips: My guess is since they are a business they'll want to sell as many as possible. But this was a Kickstarter project so I don't know how it all works.
[11:40am] yiyus joined the chat room.
[11:49am] sigblips: An interesting point about the Adapteva / Parallella 64-core chip is that they are going to use OpenCL. It will be interesting to watch how that open source project works out. It could be great and it could be a big mess. We'll have to wait and see.
[11:58am] sigblips: One more thing. Yesterday the setiQuest forum passed 6000 members. That is a lot. Why aren't more people talking?
[11:59am] dk3232: people dont know what to do after they sign up
[12:02pm] sigblips: That is a good point.
[12:09pm] sigblips: This concludes the weekly community IRC meeting. See you next week. The transcript is in the forum. Bye.

Spam query

So much for moderated forum stopping spam, why am I seeing a spam for handbags?

leaky bucket of spam

Hello Dave,

That's why I said the spam problem is like trying to fix a leaky bucket. You patch one of the holes and the spam starts leaking out of a new hole. Then you patch the new hole and repeat.  So far I have patched 7 Drupal spam vectors.  The spammers are crafty and Drupal is one very leaky bucket!

The world didn't see the recent handband spam you mentioned.  You saw it because you are a blog admin.  I fixed that leak.  Please let me know if you see any more spam. Thanks.
