[11:00am] jrseti_: Hello!
[11:00am] sigblips: Welcome back.
[11:00am] jrseti_: Thanks
[11:00am] jrseti_: http://setiquest.org/forum/topic/community-meeting-2012-08-21
[11:01am] jrseti_: I read te transcript of the last meeting
[11:01am] sigblips: 5) Happy 35th birthday Voyager 2. http://www.msnbc.msn.com/id/48738978/ns/technology_and_science-space/#.U...
[11:01am] sigblips: So you saw that last week was something else's 35th?
[11:02am] jrseti_: wow
[11:03am] sigblips: Not wow but Wow!
[11:03am] jrseti_: :)
[11:03am] jrseti_: So, shall we start?
[11:03am] jrseti_: I need to build a new distro with the latest SUSE and ALL the necessary software installed
[11:03am] sigblips: What are your thoughts on last week's Arecibo tweets in space transmission?
[11:04am] jrseti_: I did not see that. Explain.
[11:05am] sigblips: The links are in last weeks transcript. Basically a group was going to celebrate the 35th anniversary of the Wow! signal by transmitting a bunch of tweets into space from Arecibo.
[11:06am] sigblips: That appears to violate a bunch of SETI transmission protocols but no one seems to care. Just wondering what the SETI Institute's thoughts / comments are.
[11:07am] jrseti_: No one cares! I like the Will Smith one
[11:07am] sigblips: Also since SRI manages both the ATA and Arecibo, this gets more interesting ...
[11:08am] sigblips: I care!
[11:08am] jrseti_: OK, a few care.
[11:09am] jrseti_: I can tell you about my Greenbank trip...
[11:09am] jrseti_: I'm sure you know, it is a 300meter dish in West Virginia
[11:09am] sigblips: OK but before that, back to the SonATA distro.
[11:09am] jrseti_: OK, distro. 'll create a new one
[11:09am] sigblips: Are you planning on including stuff like Java?
[11:09am] jrseti_: haven't heard from Khrm
[11:10am] jrseti_: I think I should include everything.
[11:10am] sigblips: He hasn't been around here for a while.
[11:10am] sigblips: Are you thinking about including a snapshot of the SonATA source code and binary?
[11:10am] jrseti_: I'll get it all working with the latest OpenSUSE and make the VMWare file available.
[11:11am] jrseti_: everything
[11:11am] jrseti_: why not
[11:11am] sigblips: Might not want to include the Voyager 2 test file because is rather large.
[11:12am] sigblips: 310 MB !!!
[11:12am] jrseti_: They'll have to download it anyway
[11:13am] jrseti_: right?
[11:13am] sigblips: I've been playing around with VMware Fusion lately. Did you know that there is a free VMware Player for Windows and Linux? But not for Mac.
[11:14am] jrseti_: Oh well
[11:14am] sigblips: I've heard that the new free VMware Player can even create VMs but that seems crazy since it would eat into VMware's for-sale-products. Hmmm.
[11:15am] jrseti_: yes
[11:16am] sigblips: If you plan on upgrading your Mac to Lion or Mountain Lion make sure that you do a software upgrade of VMware Fusion first, otherwise things get a little tricky.
[11:16am] jrseti_: Thanks for the advice
[11:17am] jrseti_: I don't think I'll upgrade. I'll probably get a new computer first
[11:18am] jrseti_: Next?
[11:18am] sigblips: By software upgrade I meant the free in app upgrade to the next sub version option. I've heard that they are working on a 7.1 beta specifically for Mountain Lion, not sure if it will be free.
[11:18am] sigblips: Yes, next topic.
[11:19am] jrseti_: https://science.nrao.edu/facilities/gbt/
[11:19am] jrseti_: I spent 6 days there. Really a nice place.
[11:19am] sigblips: I heard that NSF is planning to cut its GBT funding.
[11:19am] jrseti_: I went to the CASPER workshop
[11:19am] jrseti_: https://casper.berkeley.edu/
[11:19am] jrseti_: Yes, the news came last week.
[11:20am] jrseti_: They may do that. It is still up in the air
[11:20am] jrseti_: CASPER is open source hardware and software for radio astronomy
[11:21am] jrseti_: Quite a few projects around the world use it
[11:21am] sigblips: NSF GBT funding. http://twitter.com/TheNRAO/status/236473869983178752
[11:21am] jrseti_: There were a lot of talks and some coding tutorials
[11:22am] jrseti_: See http://www.nrao.edu/pr/2012/portfolio/
[11:22am] sigblips: Are the ATA's FPGA beamformers based on CASPER?
[11:22am] jrseti_: The GBT's annual cost of operation is about 0.7 percent of the annual federal budget for astronomy and astrophysics
[11:23am] jrseti_: Yes, they use the BEE2
[11:23am] jrseti_: https://casper.berkeley.edu/wiki/BEE2
[11:23am] jrseti_: But the BEE2 is getting old and the software tools to support it are becoming obsolete
[11:24am] sigblips: So what is the upgrade option / plan ?
[11:25am] jrseti_: So best that we start learing about the new stuff
[11:25am] jrseti_: The plan now is to get educated in-house
[11:25am] jrseti_: need to learn how to program the Roach2 and GPUs
[11:26am] jrseti_: https://casper.berkeley.edu/wiki/ROACH2
[11:27am] sigblips: How much $$$ are those boards?
[11:27am] jrseti_: Don't quote me, but I think $7k-ish
[11:28am] sigblips: Is that with or without the 8 x 10 GbE ports?
[11:28am] jrseti_: All designed open source. You can make your own!
[11:28am] jrseti_: I think with
[11:29am] sigblips: I'm warming up my soldering iron and downloading the schematics right now!
[11:29am] jrseti_: Good
[11:29am] jrseti_: The hard part is the FPGA programming.
[11:29am] jrseti_: They use a program called simulink
[11:30am] sigblips: Everyone always thinks the software is the easy part. (:
[11:30am] jrseti_: http://www.mathworks.com/products/simulink/
[11:30am] jrseti_: not easy
[11:31am] jrseti_: Not much more to say about all of that. I'm stillthinking about what best to do and then propose it to Gerry.
[11:32am] sigblips: I wonder how the performance of Simulink compares to natively programming the FPGAs?
[11:32am] jrseti_: HDL is really hard. Sumulink makes it much more accessible.
[11:33am] jrseti_: Simulink
[11:33am] jrseti_: I asked the same question also.
[11:33am] jrseti_: The point is that what you do should be shared in the community. If you write in HDL most people can't make sense of it
[11:34am] sigblips: Yes but every company I've worked for / with does it natively. No one would ever consider Simulink for a shipping product. I've heard that Simulink is great for quick prototypes though ...
[11:35am] jrseti_: But a company does not have to share their code - and also they hire people who understand the code
[11:36am] sigblips: Yup, the leveraging of what CASPER has already done is valuable / important.
[11:36am] jrseti_: SETILive - still they same. They are working on it!
[11:37am] jrseti_: But, SonATA is ready
[11:37am] sigblips: I've noticed a new SETI Live frequency tuning.
[11:37am] sigblips: In the 4 GHz range.
[11:39am] jrseti_: Yes, we covered the lower crowded bands and jumped up in frequency
[11:39am] sigblips: Progress ...
[11:40am] jrseti_: yes
[11:40am] jrseti_: Did you see the Wiki link on the main setiquest.org page?
[11:40am] sigblips: Yes, I like it, thanks.
[11:41am] jrseti_: Now the Wiki will get too many visitors and crash the server ;)
[11:41am] sigblips: That's the plan.
[11:41am] jrseti_: anything else?
[11:42am] jrseti_: to discuss?
[11:42am] sigblips: Nope. Not much setiQuest spam this past week.
[11:42am] jrseti_: good
[11:43am] jrseti_: Thanks for the conversation. Talk to you next week
[11:44am] sigblips: You're welcome. Good meeting. Talk to you later. I'll post this transcript in the setiQuest forum. Bye.
[11:44am] jrseti_: bye
