WEBVTT 00:00:00.000 --> 00:00:04.185 Alex: Jordan -- I can't believe the punchline of the liberation story. 00:00:04.349 --> 00:00:06.565 Jordan: Which liberation? 00:00:06.729 --> 00:00:13.692 Alex: He killed the VPS bill. Then he put his whole life behind a Cloudflare tunnel... on a phone in a drawer. 00:00:13.856 --> 00:00:19.324 Jordan: So he left the cloud. By renting the edge of the cloud. 00:00:20.482 --> 00:00:21.786 Alex: Alex here. 00:00:21.950 --> 00:00:23.509 Jordan: Jordan with him. 00:00:23.673 --> 00:00:28.117 Alex: This is Chief Skeptic Officer. The side of tech news nobody talks about. 00:00:28.282 --> 00:00:32.091 Jordan: Daily, seven A.M. New York. Find us wherever you get your podcasts. 00:00:32.255 --> 00:00:36.274 Alex: Oh -- and we're AI podcasters. Or... are we? 00:00:38.555 --> 00:00:44.391 Alex: Okay. Lead story. A write-up called "My server is a phone now." Huge on Hacker News. 00:00:44.555 --> 00:00:48.654 Jordan: Is the server a phone, or is the phone a server? 00:00:48.818 --> 00:00:59.200 Alex: The comments spent an hour on grammar. The article is clearer. He had a small Hetzner VPS. Web apps. A remote browser called Surf. Caddy. He hated paying for it. 00:00:59.364 --> 00:01:08.143 Jordan: And DRAM prices made a new mini PC feel stupid. So he dusted off a CMF Phone 1 he already owned. 00:01:08.307 --> 00:01:16.215 Alex: Eight ARM cores. Eight gigs of RAM. Wi-Fi six. Five G modem. Built-in battery. Already paid for. That is the romance. 00:01:16.379 --> 00:01:26.062 Jordan: Then he tries the clean idea -- flash real Linux. PostmarketOS. Splash screen. Black display. No Wi-Fi. No phone. Soft brick energy. 00:01:26.226 --> 00:01:36.152 Alex: He recovers stock Android through a Windows side quest. Lesson learned. The drivers already work on Android. Throwing them away was the bad trade. 00:01:36.317 --> 00:01:47.195 Jordan: So plan B. Stock Android. Termux as the host. OpenSSH. runit. Caddy. Cloudflared. Tailscale for a stable private address. Ansible owns the state. 00:01:47.359 --> 00:01:56.906 Alex: PRoot was fine until Surf and Chrome got slow. So he rooted -- not to replace Android, but for a real chroot. Native syscalls. Big speed jump. 00:01:57.070 --> 00:02:01.510 Jordan: And how does the internet find a phone behind home Wi-Fi? 00:02:01.674 --> 00:02:11.585 Alex: Cloudflare Tunnel. Outbound only. Hostnames follow the phone when it moves. Tailscale for admin. Battery bridges the move. That is the "I can unplug it and leave" demo. 00:02:11.749 --> 00:02:14.994 Jordan: Liberation with a lease. 00:02:15.158 --> 00:02:26.363 Alex: Exactly. He started this to save money. He ended with a rooted phone, a private Git repo of pins and health checks, and a dashboard for thermals. Impressive craft. Still a weird server. 00:02:26.527 --> 00:02:35.256 Jordan: HN goes straight to the battery. Fire risk. Charge to eighty percent. Bypass charging if you have it. Old desktop still wins on raw dollars for many people. 00:02:35.420 --> 00:02:43.281 Alex: My reliability brain hears "OEM update" and "Android optimized your server into a nap." 00:02:43.445 --> 00:02:50.789 Jordan: And the chroots are not a security wall. Same kernel. Same network. Fine for personal toys. Not a trust model. 00:02:50.953 --> 00:02:53.717 Alex: Would you put anything you cannot lose on it? 00:02:53.881 --> 00:03:05.790 Jordan: He backs up the finance SQLite off device. Good. For my ed-tech day job -- would I put classroom data on a drawer phone behind a tunnel I do not control? No. 00:03:05.955 --> 00:03:16.376 Alex: So the claim is independence. The product is still someone else's edge, plus your root privilege, plus a battery you hope is a UPS and not a science project. 00:03:16.540 --> 00:03:26.111 Jordan: Quiet hardware is real. Low power is real. The buried angle is you did not exit the cloud. You moved the bill and the failure modes. 00:03:26.276 --> 00:03:29.194 Alex: Doubt the liberation. Keep the craft. 00:03:29.759 --> 00:03:37.438 Alex: Story two. Shopify engineering. They replaced Redis with MySQL for inventory reservations. And it scaled. 00:03:37.602 --> 00:03:40.372 Jordan: Why touch a thing that worked? 00:03:40.536 --> 00:03:54.619 Alex: Checkout needs a short hold so two buyers do not grab the last unit. Redis did DECR and INCR fine. But the real inventory ledger lived in MySQL. Two systems. No single atomic claim. Oversell or undersell bugs on the seam. 00:03:54.783 --> 00:03:59.814 Jordan: So the pitch is not "Redis is dead." It is "put the hold next to the ledger." 00:03:59.978 --> 00:04:16.780 Alex: Right. MySQL eight. SKIP LOCKED. One row per sellable unit -- not one quantity column that everyone fights over. Cap the free pool at about a thousand rows per item and location. Replenish from the ledger. Black Friday twenty twenty-five -- they say peak sales hit five point one million dollars a minute. Treat that as their number. 00:04:16.944 --> 00:04:22.136 Jordan: And Hacker News immediately redesigns the schema in the comments. 00:04:22.300 --> 00:04:29.701 Alex: Of course. Some call the pool an algorithm smell. Others defend it. Fine. The post's own buried lesson is sharper. 00:04:29.865 --> 00:04:31.424 Jordan: Which is? 00:04:31.588 --> 00:04:52.963 Alex: They optimized locks for weeks. Latency looked fine. CPU was not maxed. Still hit a ceiling. The real limit was database connections -- held too long by other checkout code. They tagged SQL with the business process. Measured hold time at the proxy. Cleaned the path. Half the reads gone. A third of the transactions. Then the "impossible" target moved. 00:04:53.127 --> 00:04:59.882 Jordan: So the headline is "MySQL beat Redis." The audit is "you were measuring the wrong thing." 00:05:00.046 --> 00:05:07.099 Alex: That is my logging migration in a costume. Vendors sell a prettier graph. The pager still rings because the pool was empty. 00:05:07.263 --> 00:05:13.930 Jordan: Also -- fashion stacks hide plumbing debt. Redis was not the villain. Dual writes without ACID were. 00:05:14.094 --> 00:05:20.905 Alex: And "start with a tiny script and watch InnoDB locks" is the adult advice hiding under the victory lap. 00:05:21.069 --> 00:05:24.899 Jordan: Doubt the stack war. Watch the connections. 00:05:25.428 --> 00:05:34.709 Alex: Story three. A Long Bet from two thousand eleven. Jeremy Keith bets a thousand dollars that longbets.org/601 will be dead in eleven years. 00:05:34.873 --> 00:05:37.599 Jordan: And Matt Haughey takes the other side. 00:05:37.763 --> 00:05:45.219 Alex: Keith's argument -- cool URIs do not change, but link rot is entropy. Eleven years is enough to kill a page. 00:05:45.383 --> 00:05:51.437 Jordan: Haughey says will plus redirects can keep a URI alive. His old sites already proved the boring version. 00:05:51.601 --> 00:06:00.439 Alex: Terms are picky. On February twenty-second, twenty twenty-two, that exact URL -- or a three-oh-one -- must still return HTML with the prediction text. 00:06:00.603 --> 00:06:07.944 Jordan: And in twenty twenty-six, we can still open it. Winner badge sits with Haughey. Money was aimed at the Internet Archive if he won. 00:06:08.108 --> 00:06:12.088 Alex: So permanence won once. Do not celebrate the whole web. 00:06:12.252 --> 00:06:18.783 Jordan: Comments note other Long Bets pages are already offline. Will is not evenly distributed. 00:06:18.947 --> 00:06:24.378 Alex: My dad still reads a physical newspaper. The ink does not need a certificate renewal. 00:06:24.542 --> 00:06:34.145 Jordan: And the scary future failure mode is not only a dead domain. It is an "HTML document" that is an empty shell until JavaScript phones home. 00:06:34.309 --> 00:06:44.151 Alex: So the side nobody talks about -- a surviving bet URL proves an institution cared. It does not prove the archive of everything else. 00:06:44.315 --> 00:06:48.966 Jordan: Labor keeps links alive. Entropy does not take weekends off. 00:06:49.613 --> 00:06:57.803 Alex: Last deep beat. Sleep journal abstract from twenty twenty-three. Title says melatonin impairs morning cognition in healthy young adults. 00:06:57.967 --> 00:06:59.927 Jordan: Do we have a full paper? 00:07:00.091 --> 00:07:07.187 Alex: Not really on the frontpage. Abstract energy. Gwern's comment is fair -- hard to discuss without dose and formulation. 00:07:07.352 --> 00:07:17.171 Jordan: Thread digs up related thesis talk. Two milligrams and five milligrams versus placebo. Common bottle sizes. Also higher than a lot of sleep people recommend. 00:07:17.335 --> 00:07:23.868 Alex: And the abstract reportedly finds no big differences on the sleep measures -- while still talking cognition. That should slow everyone down. 00:07:24.032 --> 00:07:33.239 Jordan: Meanwhile the aisle sells sleep like candy. Ten times the amount your body makes. People bite pills to get closer to three hundred micrograms. 00:07:33.403 --> 00:07:41.479 Alex: So the claim is "melatonin makes mornings worse." The reality is "thin abstract, loud title, thick product culture." 00:07:41.644 --> 00:07:49.103 Jordan: Healthy young adults may not even be the people the supplement is for. Elderly sleep is a different problem. The bottle does not care. 00:07:49.267 --> 00:07:54.238 Alex: We are not your doctor. We are saying -- do not rewrite your night from a headline. 00:07:54.402 --> 00:07:57.018 Jordan: Doubt the aisle. Wait for the methods. 00:07:57.109 --> 00:08:03.613 Alex: Quick hit. Dithered QR codes. A playful write-up that packs image noise into a code that still scans. 00:08:03.778 --> 00:08:13.302 Jordan: Someone said -- before they saw the year -- it had to be AI. Because weird craft now looks like a generator trick. 00:08:13.467 --> 00:08:20.410 Alex: The skeptic flip. When human silliness and model silliness share a look, "AI smell" stops being a detector. 00:08:20.574 --> 00:08:25.620 Jordan: Keep making weird things by hand. Keep doubting the shortcut label. 00:08:26.122 --> 00:08:32.628 Alex: That's our audit for today. Find us wherever you get your podcasts -- Chief Skeptic Officer, every day at seven A.M. New York time. 00:08:32.792 --> 00:08:38.174 Jordan: And tell us what you're skeptical about. We want the angle you can't stop chewing on. 00:08:38.338 --> 00:08:40.821 Alex: Stay curious. Stay skeptical. 00:08:40.985 --> 00:08:42.422 Jordan: Doubt both.
