[1768.18 --> 1771.02] So is it essentially then creating a mesh network between your machines?
[1771.38 --> 1771.58] Yep.
[1771.96 --> 1772.38] Aha.
[1772.98 --> 1776.26] And do they have a server component that they're running that is involved?
[1776.82 --> 1778.34] It uses WireGuard under the hood.
[1778.34 --> 1779.68] This sounds pretty slick.
[1779.78 --> 1786.28] So they must have a component that is doing some of the client negotiation, maybe key exchange.
[1786.38 --> 1789.92] They must have a server side to this that's involved to help coordinate all of this?
[1790.18 --> 1790.62] They do.
[1790.82 --> 1791.96] It runs on their servers.
[1792.34 --> 1800.08] And it's an intermediary that you have to trust, I suppose, as part of the product that comes out of the box.
[1800.08 --> 1809.92] However, there is an open source self-hosted implementation of these third-party witness nodes, whatever you want to call them, called HeadScale.
[1810.04 --> 1811.60] We'll put a link to that in the show notes.
[1811.80 --> 1813.06] And you can self-host this thing.
[1813.28 --> 1817.20] And this will become something you would, for example, run on Linode.
[1817.20 --> 1822.32] And then all of your different devices would talk back to that central host for discovery.
[1822.64 --> 1825.48] And then from there, they do all their clever routing between each other.
[1825.48 --> 1829.90] And it looks like the way the system works is the private keys are generated on each node.
[1830.02 --> 1832.00] So it's not like they have access to those private keys.
[1832.08 --> 1836.20] And then it's using WireGuard as the backend implementation.
[1836.44 --> 1839.96] And it looks like on some operating systems or maybe all they're using the WireGuard Go client.
[1840.62 --> 1841.90] I mean, all that's really solid.
[1841.98 --> 1846.50] And I find WireGuard to be extremely trustworthy and very performant as well.
[1846.58 --> 1847.50] So that's kind of a win-win.
[1847.64 --> 1850.58] So it's tailscale.com to see more.
[1850.58 --> 1854.10] I would have accidentally locked myself out of my US network a few days ago.
[1854.26 --> 1856.46] I was working on the site-to-site WireGuard VPN.
[1857.12 --> 1861.14] And for some reason, when I brought up the interface in Raleigh on OpenSense,
[1861.68 --> 1867.38] the second WireGuard interface would cause the primary WireGuard interface to go down.
[1867.64 --> 1869.20] I still haven't figured out why.
[1869.98 --> 1875.62] But without tailscale running on a VM inside my network, I would have been totally locked out.
[1875.92 --> 1877.98] There would have been nothing I could have done.
[1877.98 --> 1882.10] But luckily, I was able to route all my traffic through the tailscale system,
[1882.62 --> 1885.60] get shell access back to OpenSense, and then fix it from there.
[1886.12 --> 1886.78] Nicely done.
[1886.92 --> 1888.48] That's a good little score, Alex.
[1888.78 --> 1890.62] Tailscale, I'll have a link to that in the show notes.
[1890.64 --> 1892.84] And I think I'm going to try it out after the show today because
[1892.84 --> 1896.34] they have a ARM version for Linux on the Raspberry Pi.
[1896.56 --> 1898.72] I knew you'd like it just because it has Raspberry Pi support.
[1898.90 --> 1900.36] You know, you're a cheap date.
[1901.26 --> 1902.48] You do know me well.
[1902.64 --> 1903.46] That's very true.
[1905.26 --> 1907.08] linode.com slash SSH.
[1907.08 --> 1910.66] Go there to get $100 in 60-day credit on a new account.
[1910.76 --> 1912.68] And of course, you go there to support the show.
[1912.80 --> 1915.36] And we love using the cloud where it makes sense.
[1915.44 --> 1917.06] We're all about self-hosting on the show.
[1917.26 --> 1919.50] But there's clearly a role for cloud.
[1919.96 --> 1924.72] And we just practically make use of that whenever it seems like the way to go.
[1924.80 --> 1927.44] And Linode is always the place we deploy.
[1927.78 --> 1929.32] They have super fast infrastructure.
[1929.52 --> 1933.22] In fact, they've just recently invested more in the infrastructure.
[1933.22 --> 1939.52] And in their block storage, they've put in brand new screaming fast MBME drives.
[1939.94 --> 1941.50] They are their own ISP.
[1941.64 --> 1945.48] So they own the links between their 11 data centers around the world.
[1945.60 --> 1951.36] On their dedicated CPU rigs, they have super high-end AMD EPYC processors that kick the butts
[1951.36 --> 1952.76] of all the other cloud providers.
[1952.76 --> 1956.30] I mean, they take the infrastructure really seriously.
[1956.62 --> 1961.02] And I had a server outage here at the studio, our physical server here in the garage.
[1961.28 --> 1963.20] And I knew things were looking kind of bad.
[1963.38 --> 1967.82] So I just set up a Linode with the very bare essentials that this box does.
[1967.94 --> 1969.64] I just set it up ready to go powered off.
[1969.64 --> 1974.86] And sure enough, turned out, like, it sat there for a few weeks.
[1975.10 --> 1976.90] And I thought, oh, maybe I'll go through this whole road trip.
[1976.94 --> 1977.88] I don't ever need to fire it up.
[1978.06 --> 1982.72] But no, the last two weeks of the road trip, I ended up signing to my Linode dashboard and
[1982.72 --> 1983.92] firing up that backup machine.
[1984.00 --> 1985.74] And I was so thankful I had it.
[1985.76 --> 1990.36] And when you look at Linode's pricing, 30% to 50% cheaper than, like, the big duopoly
[1990.36 --> 1993.18] hyperscalers, that's a great value.
[1993.64 --> 1997.02] And if you want to deploy Nextcloud, for example, and you want to see if it works for you, and
[1997.02 --> 2002.30] maybe you don't want to spend several days learning how to set up the entire Nextcloud stack.
[2003.04 --> 2006.94] Well, if you go to linode.com slash SSH and you create an account and you get that $100
[2006.94 --> 2009.56] credit, you could deploy Nextcloud in seconds.
[2009.66 --> 2011.64] They have, like, a one-click deployment for Nextcloud.
[2011.96 --> 2015.46] They have one-click deployment for Discourse if you want to go build a community.
[2015.92 --> 2019.34] Or maybe you're looking at replacing Zoom with something self-hosted.
[2019.60 --> 2021.92] They have a one-click deployment for Jitsi as well.
[2021.92 --> 2026.92] And I think you'd be shocked at how great a self-hosted Jitsi instance is and how
[2026.92 --> 2028.68] much better it can be than using Zoom.
[2029.16 --> 2032.90] And it's way cheaper if you want, like, the pro Zoom stuff and you're in control.
[2033.14 --> 2036.88] They have a lot, way more than I could ever list, just one-click stacks.
[2037.06 --> 2038.64] Or you can go the DIY route.
[2038.76 --> 2039.76] It's up to you.
[2040.14 --> 2041.62] Development tools, game servers.
[2041.76 --> 2043.32] Linode makes it easy to get going.
[2043.66 --> 2047.32] And then they have a bunch of great services like S3-compatible object storage, which is
[2047.32 --> 2051.48] fantastic for backups, DDoS protection, VLAN support, a powerful DNS manager.
[2051.48 --> 2053.92] I mean, on and on and on, you guys.
[2054.60 --> 2058.38] So I'll just leave it to you to go figure it out, to go try it for yourself, because I
[2058.38 --> 2059.26] know that's how I learn.
[2059.58 --> 2065.14] So go to linode.com slash SSH, get that $100 in 60-day credit on your new account, and you
[2065.14 --> 2065.78] support the show.
[2066.26 --> 2068.58] Linode.com slash SSH.
[2070.66 --> 2074.78] So after road trips, I always like to ask you what your learnings have been and stuff like
[2074.78 --> 2074.96] that.
[2075.02 --> 2079.04] And I would imagine the primary theme from this trip was managing heat.
[2079.04 --> 2080.64] Oh my goodness, yes.
[2081.12 --> 2086.82] When you were on your way to Chicago, I was trapped in Tucson, where I think every day
