07:04 < kanzure> z80 only has 8500 transistors?
07:06 < kanzure> looks like it has some speed issues, he could virtualize parts of code execution and then pick and choose which parts of execution to visually represent in larger programs

12:53 < maaku> L29Ah: it seems the full size spin launch setup releases the payload at a speed that coincidentally happens to be lunar escape velocity
12:53 < maaku> I'm guessing they're playing the long game here
13:13 < fenn> it's the only use for the technology
13:14 < fenn> shh don't tell the investors
13:15 < fenn> kanzure: time for cryptographically signed science publishing
13:15 -!- Codaraxis [~Codaraxis@user/codaraxis] has joined #hplusroadmap
13:22 < fenn> hehe "Sea level height based on big data of Internet of Things and aerobics teaching in coastal areas"
13:30 < fenn> reminds me of the grievance studies affair
13:59 < fenn> https://en.wikipedia.org/wiki/Radio_resource_location_services_protocol  supports time of flight positioning O_o
13:59 < fenn> "many high-end smart-phones submit their GPS location to the mobile operator when requested. This happened without any sort of authentication."
14:27 < maaku> I'm sure the investors know.
14:28 < maaku> I thought spin launch was a joke, the pets.com of the space bubble
14:28 < maaku> There is over 100 space launch startups, all jockying for a market that spacex is making obsolete.
14:29 < maaku> But if they're really targeting lunar mass return, then they're one of the few companies actually aiming for a post-Starship future
14:30 < maaku> Starship will be incredibly capable for delivering mass to the moon. The rocket equation makes it suck big time for bringing mass back though. And methane is about the worst chemical fuel you could pick for lunar ISRU.
14:42 < muurkha> hmm, if that's because hydrogen is rare, then hydrogen would be worse than methane.  and if it's because carbon is rare, then kerosene would be worse than methane.  what's special about methane here?
14:46 < maaku> kerosene would be worse but it's not used for in-space thrusters afaik
14:47 < maaku> LOX/H2 is the most common upper stage fuel combo, and would work pretty well on the Moon
14:49 -!- spaceangel [~spaceange@ip-62-245-71-160.net.upcbroadband.cz] has quit [Remote host closed the connection]
14:52 < maaku> and yes it's because carbon is rare, and where it does exist is not trivial to process without an atmosphere
14:52 < maaku> hydrogen in the form of water is probably very common in the regions of the moon we're likely to explore
14:53 < muurkha> hopefully.  it might not be that widely distributed
15:04 < fenn> there is carbon and water on the lunar surface, so i don't see the problem with methane
15:04 < fenn> somehow this fact is lost on the space industry
15:06 < fenn> http://www.universetoday.com/76329/water-on-the-moon-and-much-much-more-latest-lcross-results/ http://www.universetoday.com/76365/understanding-the-unusual-lcross-ejecta-plume/
15:08 < fenn> most of your mass is oxygen anyway
15:13 -!- Hooloovoo [~Hooloovoo@hax0rbana.org] has quit [Ping timeout: 260 seconds]
15:15 < muurkha> well, until Lunar Prospector we thought there wasn't any hydrogen; maybe most people haven't updated
15:15 < muurkha> that was only, what, 23 years ago?
15:17 -!- Hooloovoo [~Hooloovoo@hax0rbana.org] has joined #hplusroadmap
15:17 < fenn> i think the general misunderstanding is that there's water but not any other volatiles
15:17 < fenn> which doesn't make sense if you think about it
15:17 < fenn> carbonaceous chondrites impact all the time
15:17 < fenn> that's probably where the water came from
15:18 < maaku> fenn: water also comes from solar wind interacting with the surface, then sputtering around until it hits a cold trap
15:19 < maaku> over billions of years that results in surface layer in these cold traps that could be meters thick, and maybe 5+% water by weight
15:19 < maaku> even without thinking about impacter sources
15:20 < maaku> so you can go to any permanently shadowed crater and be guaranteed to get water if you drive a harvesting rover across it
15:21 < maaku> other stuff you probably have to prospect for, unless you're content with <1% (and probably less than 0.1%) concentrations
15:21 < muurkha> like methane?
15:33 < fenn> well the "lunar prospector" happened across double digit percentages of carbon containing volatiles on the first try
15:43 < maaku> muurkha: methane, carbon monoxide, carbon dioxide, etc.
15:46 < maaku> fenn: you talking about this lunar prospector? https://en.wikipedia.org/wiki/Lunar_Prospector
15:49 < fenn> "The mission ended July 31, 1999, when the orbiter was deliberately crashed into a crater near the lunar south pole"
15:53 < fenn> ok i actually don't know what the results of that were
16:02 < nmz787> jrayhawk: I got another LTE connection, this time with Verizon towers which are visible line-of-sight from my new house... I have freshTomato on my R8000 router, but it doesn't want to let me have two 4G/LTE WANs from the GUI... and I'm not sure how to use the linux terminal it has (I believe) to set this up manually. Also want to do some sort of QoS, like VNC/SSH/MS-TEAMS go on Verizon 
16:02 < nmz787> preferentially, and if any remaining capacity is left webpages and such can use that, but then finally spills over onto the T-mobile WAN (which these days has OK bandwidth, but pretty shitty ping and jitter, which makes VNC/SSH  terribly laggy and a pain to use, and makes me paranoid about voice calls (latency and being late to break into conversation) and screensharing (tearing of the image, loss of 
16:02 < nmz787> frames if presentors are changing screens too fast )
16:03 < nmz787> soooo, I'd love some of your time to massage that system
16:03 < nmz787> bbl
16:18 < jrayhawk> What hardware setup are you using to interface with multiple LTE networks?
16:22 < jrayhawk> tasers and floor sausages
16:22 < jrayhawk> whoops, wrong channel
16:25 < fenn> rofl
16:26 < fenn> must be an exciting channel
16:35 < jrayhawk> true fact
17:27 < muurkha> is the SnapGene license worth the price?

21:15 < nmz787> jrayhawk: as of earlier it was the Netgear X6 R8000 router, a franklin T9 LTE modem connected to the router via USB, and then I unsuccessfully tried using an old gogle pixel 2 for a second tethered WAN which failed
21:15 < nmz787> I have since received a Netgear LM1200 modem which includes a LAN port 
21:17 < nmz787> in the case of the pixel 2, since the phone is not known to be rootable, it tells the ISP that I'm using hotspot/tethering mode and throttles the speeds
21:17 < nmz787> ping is still good in that case
21:17 < nmz787> I am hoping the LM1200 won't tattle on me to the ISP, but expecting it will
21:18 < nmz787> I found two USB tether bypass apps, PdaNet and easytether, the latter of which has linux and even open-wrt support
21:18 < nmz787> but it's not opensource and thus I am unsure if I could use the binaries on my freshtomato build
21:19 < nmz787> I could always buy a rooted older/dead-battery verizon LTE phone
21:19 < nmz787> and hopefully I can return this modem to amazon if it doesn't produce nice results
21:40 < jrayhawk> Yeah, that sort of complex routing logic is almost certainly going to be beyond the expectations of the UX design, so you're almost certainly stuck with sshing in and providing your own interface/iptables config every time you do a firmware upgrade.
21:41 < jrayhawk> once you get ssh up and running I can help out with that. https://www.omgwallhack.org/home/jrayhawk/authorized_keys
23:23 < nmz787> my plan for that is just never upgrade the firmware
23:24 < nmz787> do I copy a whole line from your keyfile?
23:24 < nmz787> copy-paste
23:38 < jrayhawk> yeah
