[01:17] *** JesseW has joined #internetarchive.bak [02:34] *** rrn has joined #internetarchive.bak [02:35] Hi guys! I found this absurd offer---a 4 TB HDD for $20, incl. shipping: http://www.ebay.com/itm/G-Technology-4TB-G-DRIVE-G1-USB-3-0-Hard-Drive-0G03594-/122039930897?hash=item1c6a259011:g:0zAAAOSwRS9Xf9RL [02:36] most likely it's a mistake and the seller will refund all the purchases made, but who knows? [02:37] By the way, I'm the one who purchased 50 of them :). [03:06] rrn: awesome! [04:31] *** xperia64 has quit IRC (Yaaic - Yet another Android IRC client - http://www.yaaic.org) [04:50] I'm definitely going to join this project, even if I don't get those HDDs :). [04:52] I wonder if the Internet Archive includes the entirety of WP. [04:54] OSM would be another good candidate, if not already included. [04:57] WP? [05:02] Wikipedia, I presume. [05:03] rrn: It does have a number of wikipedia dumps, yes. [05:03] I'm not sure if it has every single one ever released, though. [05:03] occasionally: https://archive.org/search.php?query=wikipedia%20wikiteam [05:04] that's search will just show archiveteam stuff -- I think there are non-archiveteam copies also on IA [05:11] true [05:17] plus the wayback machine [05:17] well, I hope there aren't many wikipedia *dumps* in the wayback machine... [05:17] that would be kinda silly [05:18] why? [05:19] db48x: B/c articles tend to be incremental, with past history summarized and placed into a historical section. [05:19] they also tend to get deleted :P [05:19] dumps are rather large, and in my (imperfect) understanding, that's not preferable for stuff in the Wayback Machine... [05:20] rrn: wait, what? [05:21] * JesseW has been prompted into trying to figure out whatall wikipedia stuff is on IA [05:22] http://archiveteam.org/index.php?title=Wikipedia has a lot of links [05:26] this is great---so I'm in the process of volunteering CPU and GPU power, triaxial accelerometer readings for a non-profit earthquake monitoring project, microwave beacon transmitter, and now storage space! [05:27] nice [05:29] JesseW: microwave beacons seem to be the rarest and most esoteric (and most expensive and difficult) project out there. [05:30] hm, link? [05:31] JesseW: There is no centralized website per se, just a bunch of outdated beacon lists; I believe that there are only 20--30 of such sites in the entire US. [05:31] no, I mean, a link *describing* what it means to provide a "microwave beacon transmitter" [05:32] JesseW: Look up ``radio propagation beacon'' on WP or something. [05:33] oh cool [05:33] I'm actually working on 10 GHz...that stuff is expensive! [05:34] we should probably take this to #archiveteam-bs [05:34] so, for your microwave one -- what band? [05:35] X band, specifically 3 cm [05:36] e.g., like the *most* cheapest reasonable amplifier (used and probably from the 80s) costs in the range of $480 [05:36] for 10GHz? [05:36] 6--12 GHz, 1 W [05:37] There are TWT amplifiers from the 60s but the TWT won't last long, so that's a no-no for a 24/7 beacon. [05:38] so, who do you work with to make tests of your microwave beacon? presumably you need someone far away to find out if it got picked up... [05:38] I have a 12 GHz SA, high-end compterized microwave power meter, and 18 GHz frequency counter. [05:39] I'll hook up the last two eventually for automated self-test via GPIB, when I get to writing the self-test subsystem software. [05:41] expensive, but at least this stuff maintains its value rather than turning into trash exponentially as in the case of IT equipment [05:41] so, I'm *very* ignorant of this stuff -- are you able to make tests of the microwave propagation directly yourself, or do you merely transmit, and need others to report back where they were able to receive your signals? [05:42] They'll report back with an email typically; in the past, people wrote for QSL cards via the mail. [05:42] what's a SA? [05:43] spectrum analyzer [05:43] ah, makes sense [05:44] *** Jeroen52 has quit IRC (Ping timeout: 260 seconds) [05:44] what are some of the farthest distances that you've gotten reports from? [05:45] I'm still working on setting it up. [05:45] ah, ok [05:45] It'll vary widely b/c of rainscatter and snowscatter. [05:46] so you have the equipment for the microwave beacon, and are working on setting it up -- and you're researching the costs for the equipment for a 10Gz beacon [05:47] Well I have a high-end signal generator already; I just need a horn, more waveguide and cable, and an amplifier. [05:47] nods [05:48] And of course a FreeBSD or GNU/Linux server with audio card. [05:48] *** Jeroen52 has joined #internetarchive.bak [05:50] Low frequency stuff (like 1--2 GHz) is much cheaper, so it shouldn't be very difficult to be the first entity in the world to open an active SETI station. [05:50] hah [05:51] But I got a nice German-made, computerized signal generator that operates on like 10--18 GHz or so for almost peanuts, so I'm stuck on this band.
