Space based systems are interesting to consider — they tend to be very reliant on ground systems, but it would be technically elegant if packets from one ground station to another were delivered directly, with no other ground interaction. LEO constellations probably need near constant ground help to update orbital ephemeris, and the orbits would decay in a few years anyway, but GEO sats could continue operating for decades if their control software didn’t preclude it. There should be off grid (or even in-space) servers connected to the satellite networks at static IP addresses (so DNS isn’t required). The Website For The End Of The World. What would a sparsely distributed group of apocalypse survivors want to see there? A Wikipedia mirror and some type of forum for communication, certainly. It seems like a good story element, but a little real world LARPing along those lines would be fun. The tragedy would be when all the terminals maintaining a fragile network of communication among humanity shut down due to the account billing servers being unavailable.</span></span><span lang=EN style='font-size:13.0pt;font-family:"Segoe UI",sans-serif;color:#0F1419'><o:p></o:p></span></p></div></div></div><div style='border:solid black 1.0pt;padding:0in 0in 0in 0in;margin-top:12.0pt;margin-bottom:12.0pt;box-sizing:border-box;display:flex;min-height:0px;min-width:0px'><div style='border:solid black 1.0pt;padding:0in 0in 0in 0in;box-sizing:border-box;display:flex;min-height:0px;min-width:0px'><div style='border:solid black 1.0pt;padding:0in 0in 0in 0in;margin-right:9.0pt;box-sizing:border-box;display:flex;min-height:0px;min-width:0px'><div style='border:solid black 1.0pt;padding:0in 0in 0in 0in;box-sizing:border-box;min-height:0px;min-width:0px'><div style='border:solid black 1.0pt;padding:0in 0in 0in 0in;box-sizing:border-box;font-variant-numeric:normal;font-variant-east-asian:normal;font-variant-alternates:normal;font-kerning:auto;font-feature-settings:normal;font-stretch:normal;min-width:0px'><p class=MsoNormal style='line-height:15.0pt'><span style='font-size:11.5pt;font-family:"Segoe UI",sans-serif;color:#536471'><a href="https://twitter.com/ID_AA_Carmack/status/1704160299845071328"><span style='color:#536471;border:solid black 1.0pt;padding:0in'><br></span></a><o:p></o:p></span></p></div></div></div></div></div></div><p class=MsoNormal><br clear=all><o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal><span class=gmailsignatureprefix>-- </span><o:p></o:p></p><div><div><div><p class=MsoNormal>Oct 30: <a href="https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html" target="_blank">https://netdevconf.info/0x17/news/the-maestro-and-the-music-bof.html</a><o:p></o:p></p></div><div><p class=MsoNormal>Dave Täht CSO, LibreQos<o:p></o:p></p></div></div></div></div></div></body></html>
