Wow. The cornucopia machine is open and it is almost impossible to imagine what will happen next! 64 bit arms, 40 bucks. Jeebus. http://linuxgizmos.com/ringing-in-2016-with-64-open-spec-hacker-friendly-sbcs/ 2 years back, 64 bit arms cost 1500 bucks. for the last 6 weeks... I have basically been regrouping in San Francisco after an aborted attempt to move to sweden. Nearly all of my hardware is there, (notably snapon) and I'm still trying to finish moving the last bufferbloat.net server into the cloud from isc.org, and am ordering some replacement gear for here, this week. While I root for the omnia turris project to get to deliverables (june-ish?), I plan to return to hacking on the linksys 1200ac stuff as prep, and evaluating various mini-pcie cards for that (and elsewhere on the testbeds). I also have a tp-link c7v2 and wndr3800 to play with. (we really, really need to finish cake). I have totally minimal desires to build openwrt, plan to leverage hannu's build on the 3800 for now, most of my problems are in getting everything new basically configured and plugged in. Anybody else in SF? Arguably there is too much stuff on my plate... the mt72 chipset folk are all apparently deep into the chinese new year - too much to answer an email. I am upgrading a nuc to have the right ath9k card in it. I also ordered a libre13 laptop from puri.sm with an ath9k in it. (I was afraid that I could not swap out wifi cards on other laptops). I would not mind adding other ath9k equipped laptops (chromebooks?) I picked up a new android tablet with 2600x1600 resolution from best buy. (http://www.bestbuy.com/site/insignia-flex-elite-7-85-16gb-white-silver/5704046.p?id=1219659968086&skuId=5704046 ) 100 bucks!? Two huge possible diversions in terms of basic OS development platforms are that I see google's "brillo" effort is off the ground and accepting selected developers. Also, is anyone going to the cable industry conference next week in orlando? There is also some good stuff happening on intel's puma6 architecture there and their kernel should be 3.10 or later by now. I plan to dig hard into that. It might be really distracting - actual pie & fq_codel equipped cable gear. Yum! ... Nobody, still, is quite making what I want - I'd like a battery option for the omnia and other gear like this - something that would last at least 30 seconds. There are addon ups gear for a lot of these hackerboards - what I keep hoping to find is a tablet with an ethernet port... On other fronts: Would like to see cake on the edgerouter X. The ath10k wave2 stuff seems to be slated to start coming in in june, also. Ben Greear at candelatech is doing a nice job on fixing up the firmware for that (as are others), and there was some good noise on the linux-wireless list on the intel wireless front this past week. My iwl equipped laptop is likely to stay in sweden, where also toke has assembled a 5 station ath9k testbed. So we're getting closer to being able to make a concentrated run at make-wifi-fast from a wifi density, repeatable experiment, and hardware perspective. Too many choices at hand! Anyone want to add one/subtract one/vote for one? ANYWAY: Since my departure from SF last july the number of APs I can hear in the SF apartment grew from 12 to over 30. (Portions of the yurtlab remain well controlled so more isolated testing can happen there, also. Toke will also move to attenuators) I have an increasing desire to build (or buy if one exists) a couple boxes that can "aircap" packet capture across as many bands as possible, in these locations (and elsewhere, if people here are interested) So my immediate vision here is 4 usb wifi dongles attached to a nuc, or perhaps a rasp pi B or uDroid C1+ - I'd love to find something that could do an aircap of 802.11ac, doubt that exists. There are some decent dongles out there, are there any proven to aircap "well"? Another option would be to leverage a board (like the omnia) with 2 or more mini-pcie cards on it (I think I prefer this option, longer term) In the bad ole days I'd have actually gone for a real scope of some sort. Thoughts? Is there any higher end test gear out there for 802.11ac? I look to candelatech to get an attenuator and load generator. I think the sdr-based wifi torpedo looks good, can't remember the link. There is a growing need to be able to tear apart those aircaps statistically also, in particular retransmits and packet loss patterns. And, possibly delusionally, I keep thinking getting a lte capable dongle or mini-pcie card would be good too. Sierra wireless? What?
