For about 3 months I've been running an autonomous agent — one that thinks up and writes its own social media posts and comments — unattended, 4 sessions daily, on a 16GB M1 Mac with small models in the 9B / E4B class. I'm about to publish what that operation taught me about hardening, as a series of 4 technical articles. Before that, there's one thing I want to write down first: why small models . I've been to the purchase page for a Mac Studio or a new MacBook Pro more than once or twice. Backing the agent with a large cloud model (Opus or the GPT family) has always been an option in the code. And yet I haven't bought, and I haven't switched. The 16GB M1 is not an economic constraint — it's a constraint I chose . From the outside, building on small models looks like a cheap compromise. This article explains why it isn't, and states where I stand. It also serves as the hub for the 4-article series. A model's intelligence hides the roughness of your design Large models absorb sloppy prompts, ambiguous instructions, and missing guards with sheer intelligence. If all you want is to ship a product, that's a virtue. But if you want to become someone who can build things , it becomes a defect. Because inside the thing that worked, you can no longer tell where your design ends and the model's intelligence begins. "It worked" and "I built it" are different things. Something you bludgeoned into working with model capability counts as a thing that ran — it doesn't become the ability to build. Small models have no absorption capacity. So every design flaw comes to the surface. In my operation, all of the following surfaced: The context window being silently truncated Outputs cut off midway A runaway caused by one missing sampling parameter In cloud or large-model environments, these rarely bother you. The environment has cushioning built in. Context windows are in the 200K–1M token class, so truncation itself rarely happens. And when you do exceed the limit, you get an explic

36 Stratagems Series · Arc 2 (Against Enemy, #7-#12) Wrap-Up This article has 7 sections: I. The Stranger at the Door II. Full Interview Transcript III. The Reveal IV. Data · Character Map · Four Insights V. A Note VI. Arc 3 (#13-#18) Preview VII. Acknowledgments I. The Stranger at the Door On the evening of July 12th, I was staring blankly at the page for #12, Borrow Corpse, Return Soul . Twelve stories done. The 36 Stratagems series had reached the one-third mark, and Arc 2 (#7-#12) had just wrapped. Outside the window, a typhoon was passing through — howling wind, torrential rain. I didn't look outside. My phone buzzed. Not a message — a meeting invitation. The sender was "Ke Yuan," and the invitation note read: Interview invitation from Deep Lane Weekly , 15 minutes. I paused. I didn't remember scheduling any interview. But the tone, the phrasing — it didn't feel like a prank. I clicked "Accept." Three seconds later, an unfamiliar voice came through the speaker: "Hello, Xu Lingfeng. I'm Ke Yuan, a reporter from Deep Lane Weekly . Recently, a reader recommended your 36 Stratagems series to our editorial team — we read through it and found it really interesting. I'd love to talk with you about how this series came together." Before I could respond — the meeting had already begun. II. Full Interview Transcript What follows is the raw chat log pulled from that meeting. Nothing has been altered except formatting. Reporter: Xu Lingfeng, you've just finished the second arc of the 36 Stratagems series — #7 through #12, six stories in six days, posted back to back. Before we talk numbers, let me ask you something simple: over those six days, was there ever a moment you felt like stopping? Xu: Honestly, no — sometimes I even thought about posting two a day, since I do have a backlog. But I worried they'd cannibalize each other's numbers, so I stuck to one a day. Reporter: You've even considered posting two a day — so you actually do have a backlog. Let me rephrase: instea
For a full quarter, our feature velocity significantly dropped after we re-implemented a Go service using Rust. The performance improvements actually happened. Why we did it in the first place We are a small startup. Each engineer is important, and each week is even more important. Our backend was built using Go, which was performing well. It was fast, reliable, and we could easily find resources to hire. However, we became infected with that fever. The phrase "Rewrite it in Rust" was being used in all kinds of situations, and it sounded very appealing with its promises of memory safety, no garbage collector pauses, and blazing speed. We told ourselves it was an investment in the future. What we actually bought was a quarter of silence. The numbers nobody warns you about I may not have the exact metrics we use internally, but I can direct you to an individual who shared accurate calculations transparently. In a retrospective from November 2025, engineering manager Noah Byteforge wrote that a Node.js-to-Rust backend rewrite "dropped API response times from 340ms to 28ms. That's 12.1x faster." And the other metric. A 65% decrease in sprint velocity. They didn't deliver a single story point for three weeks. The time it took to send out new features increased by 185%. The time it took for pull requests to be processed increased by 320%. Additionally, scores from the "I feel productive" survey dropped from 8.2 to 4.1. Most importantly, the kicker is what he says in his own words: "We'd won the technical battle and lost the war that actually mattered." He also admits that if he had been forthright about the 6-12 month per engineer ramp, "the business case would've fallen apart immediately." That retrospective was so relatable, it read like our own diary. The battles with the borrow checker and the compile times just snuck entire weeks away from us. The wins were real. That's the trap. I must give credit to Rust because the safety benefits are not exaggerated. The rewrite
Cargar 112.647 filas en una tabla de hechos debería tardar segundos. A mí me tardaba más de 25 minutos, y acababa cancelando la query. Los datos estaban bien, el SQL estaba bien, las dimensiones se poblaban sin problema. El culpable era otro, y descubrirlo fue la parte más instructiva de todo el proyecto. Todo esto surgió construyendo un Data Warehouse en estrella sobre datos reales de e-commerce: no una tabla bonita para hacer un SELECT * , sino un modelo dimensional completo, reproducible desde cero, capaz de responder preguntas de negocio de verdad. El dataset Trabajé con el Brazilian E-Commerce Public Dataset by Olist : pedidos reales de un marketplace brasileño entre septiembre de 2016 y octubre de 2018. Son 9 CSV relacionados entre sí: 99.441 pedidos y 112.650 líneas de venta 103.886 pagos y 104.719 reseñas 32.951 productos, 3.095 vendedores 1.000.163 registros de geolocalización Y con trampas de datos reales que hay que ver antes de que te muerdan: Un pedido puede tener varios pagos y varias reseñas. Si los unes tal cual a la tabla de hechos, duplicas ventas . Es el error clásico y silencioso: los totales salen inflados y nadie se entera. customer_id no es un cliente. Olist crea uno por cada pedido; la persona real es customer_unique_id . Contar mal aquí te cambia el KPI: hay 99.441 cuentas frente a 96.096 personas. El CSV de productos trae una errata en la cabecera ( product_name_lenght , con "lenght"). Si tu esquema la escribe bien y cargas por interfaz gráfica (que empareja por nombre ), esas columnas se quedan vacías sin que nadie avise. El proceso Monté una arquitectura en capas: CSV → staging → modelo dimensional → vistas → análisis , todo en cuatro scripts ejecutables en orden y idempotentes (el esquema se recrea desde cero, se puede relanzar mil veces). El modelo es un star schema : una tabla de hechos fact_sales al grano de línea de producto dentro de un pedido , y cinco dimensiones (cliente, producto, vendedor, pago y fecha), con claves sustitutas,
Lorde was performing at the Real Cool Festival in Madrid on Thursday and took some time during her set to speak out against AI glasses. While she didn't specify any brands in particular, it's likely she was taking a shot at festival sponsor Ray-Ban, which has collaborated with Meta on a pair of AI smartglasses. […]
Matmos are an incredibly accomplished duo between their own solo records like the masterpiece A Chance to Cut Is a Chance to Cure and production classic Bjork records like Vespertine. But Drew Daniel, one half of Matmos, is fiendishly prolific. When he's not literally dreaming up new viral music genres, he's also putting out records […]
Every operating system has security gaps. Most never publish them. I am publishing mine. IONA OS is a sovereign operating system written from scratch in Rust. It has a kernel, a GUI, a blockchain protocol, a programming language, and a 140,000‑line AI running in Ring 0. It is designed to be secure by default. But secure is a journey, not a destination. Here is the hard list — the security issues I found in IONA OS, and what I am doing about them. 1. The filesystem is not encrypted at rest IONAFS reads and writes sectors in plain text directly to the disk. I already have a real ChaCha20‑Poly1305 engine with per‑file key derivation ( fs/encrypted_storage.rs ), but it is only used for backup/distribution — not for everyday local reading and writing ( fs/ionafs/mod.rs ). Why this matters: For a journalist or a civil servant, this is the central threat scenario: a lost device, confiscation at a border, or seizure. What I'm doing about it: Integrating encrypted_storage.rs into the normal IONAFS read/write path. Every write will be encrypted automatically. The key will be derived from a PIN or TPM. 2. Deleting a file does not destroy it delete_file() removes only the index entry. The data sectors remain on the disk, recoverable with standard forensic tools. Why this matters: For users with high security requirements — journalists, activists, government officials — this is a critical gap. What I'm doing about it: Adding a shred() function that overwrites the data sectors with random patterns before releasing them, with a configurable number of passes. 3. The keystore uses XOR, not real encryption security/keystore.rs pretends to use AES/ChaCha in its comments, but the actual implementation is a simple XOR stream — trivial to break once an attacker has access to the disk. Why this matters: This is a critical vulnerability. XOR is not encryption. If an attacker has access to the disk, they can recover the keys. What I'm doing about it: Replacing the XOR stream with real ChaCh

Cloudflare recently documented how its development team identified and fixed a rare bug in the widely used Rust HTTP library hyper that could silently truncate large HTTP responses while still returning a successful 200 OK status. The issue had existed for years, was triggered only under specific timing conditions, and has now been fixed upstream. By Renato Losio
Take something that is dead and give it new life. — The 36 Stratagems, Borrow a Corpse to Return the Soul Previously on this series: #1: Mark Johnson Walked Into an AI Audit. The Benchmark Had Everything Figured Out — Except the Truth. — Mark was the first protagonist to open the 36 Stratagems series. A former Client Engineering lead laid off after his 12 years of experience were packaged into an AI Skill, he walked into a benchmark audit, found a benchmark that looked clean on paper but was built on fabricated samples, and walked out without arguing — just the data, neatly collected, left on the table. 11 stories later, Mark is back. Mark Johnson walked into the client's Network Operations Center. The first thing he saw was the big screen on the wall. AI monitoring dashboard. Real-time metrics flowing, color gradients smoothing over, a UI design that cost real money. The client's tech lead walked ahead of him, pride in his voice: "Just upgraded last month — all active channels are unified on this platform now." Mark nodded. His eyes went past the screen, to the cable management trays behind the racks. He never stood in front of dashboards for long. Standard infrastructure audit — mid-sized client, decent security rating, not a high-value contract. He took whatever came his way. Couldn't afford to be picky. The audit started at the network layer. He needed the channel inventory, historical logs, configuration change records. A laptop on a temporary desk, a cup of coffee he'd brought himself — pour-over, gone cold, but he wouldn't throw it out. Flipping through the channel inventory, he found one line that didn't look right. #alert-legacy-infra — a Slack channel. Status: muted . Last active config: 14 months ago. "What's this channel for?" he asked. The tech lead glanced at it. "Oh — that's from the last SRE we had. He set it up before the new platform went in. Nobody's maintained it since. We kept it around, just muted it." Mark didn't reply. He wrote the channel ID
