자동으로 돌아가게 만든 것과, 자동으로 끝까지 처리되는 것은 다른 문장이었습니다 이 시스템은 사람 승인 없이 스스로 판단하고 매매하는 걸 목표로 설계했습니다. 실계좌 주문 실행과 안전장치 (새 창)도 그 목표에 맞춰 만들었습니다. 그런데 최근 한 달 사이 실계좌에서 세 번, 사람이 직접 개입해야 하는 상황이 있었습니다. 세 사례 모두 "왜 자동 로직이 이 상황을 못 넘겼는지"의 구조가 서로 달랐습니다. 1. 배분 규칙이 특정 주문을 구조적으로 굶겼다 특정 종목 하나가 여러 날째 매도 계획이 서 있는데도 계속 팔리지 않는 걸 발견했습니다. 시스템은 매일 이 종목을 매도 후보로 올렸지만, 실제 주문까지는 못 갔습니다. 원인은 하루 매매 한도를 여러 라운드에 나눠 배분하는 규칙이었습니다. 이 종목의 주문 금액이 그날 남은 매도 한도보다 항상 컸습니다. 라운드 순서를 아무리 바꿔도 통과할 수 없는 구조였습니다. 한도 자체는 정상 작동하고 있었습니다. 문제는 "이번엔 못 나가도 다음 기회에 나간다"는 전제가 이 종목엔 애초에 성립하지 않았다는 점입니다. 잔여 한도가 매번 주문 금액보다 작으면, 기회는 계속 오지만 한 번도 충분하지 않습니다. 당장 못 나간 주문 1건은 사람이 직접 처리했습니다. 실계좌에서 이뤄진 되돌릴 수 없는 매도였습니다. 이후 배분 규칙 자체를 손봐서 같은 구조로 다시 굶는 일이 없도록 정리했습니다. 2. 안전장치가 스냅샷과 누적치를 혼동했다 다른 날엔 반대 방향의 사고가 있었습니다. 누적 손실을 감지하는 안전장치가 정상적인 매수 2건을 잘못 차단했습니다. 지수는 그날 거의 보합이었는데, 이 안전장치가 재는 손실률은 훨씬 크게 찍혀 있었습니다. 원인을 보니 이 장치는 "고점 대비 누적 하락"을 감지하는 용도였는데, 정작 비교하는 현재값은 장중 순간 스냅샷이었습니다. 장중 잠깐의 변동이 누적 지표를 밀어 올려서, 실제로는 발동하면 안 될 상황에서 발동한 겁니다. 누적을 재는 장치와 순간을 재는 장치가 뒤섞여 있었던 셈입니다. 막힌 매수 2건은 사람이 판단해서 직접 집행했습니다. 이후 이 안전장치가 장중 순간값이 아니라 "그날 마감 대 전날 마감" 기준으로만 반응하도록 구조를 바꿨습니다. 장중 급락에는 이제 다른 안전장치가 대신 반응하도록 역할을 나눴습니다. 3. 개입 경로 자체가 "새로 사는 경우"를 몰랐다 두 번째 사례를 수습하는 과정에서 사고가 하나 더 있었습니다. 수동으로 낸 주문을 원장에 반영하는 도구를 썼는데, 반영이 안 되고 조용히 빠졌습니다. 이 도구는 사람이 손으로 낸 거래를 세 가지 경우 중 하나로 분류합니다. 기존 보유 종목을 판 경우, 기존 보유 종목을 더 산 경우, 그리고 시스템과 무관한 거래인 경우입니다. 그런데 이번 매수는 원장에 없던 새 종목을 사람이 처음 사들인 경우였습니다. 세 분류 중 어디에도 안 맞았고, 도구는 이걸 "시스템과 무관한 거래"로 잘못 넘겼습니다. 그 결과 실제로는 산 자산이 잠깐 원장 밖에 있는 것처럼 표시됐습니다. 이 도구는 애초에 사람 개입을 위해 만든 경로였습니다. 그런데 그 경로를 설계할 때, "사람이 아예 새로운 자리에 처음 진입하는 경우"는 상정하지 않았습니다. 개입 경로 자체가 개입의 한 형태를 놓치고 있었던 셈입니다. 순서(먼저 다른 매도를 부기하고, 그다음 이 매수를 부기)를 지켜서 바로 수습했고, 검증 결과 원장과 실계좌 잔고는 정확히 일치했습니다. 분류 로직에 이 경우를 추가하는 건 아직 남은 과제입니다. 세 사례를 묶어보면 셋 다 "자동으로 처리되게 만들었다"와 "실제로 끝까지 처리된다"가 다른 문장이라는 걸 보여줬습니다. 첫 번째는 규칙이 있었지만 그 규칙이 특정 입력에서 절대 통과할 수 없는 구조였습니다. 두 번째는 장치가 있었지만 재는 대상(순간 대 누적)이 설계 의도와 어긋나 있었습니다. 세 번째는 사람 개입을 위한 경로가 있었지만 그 경로 자체가 특정 개입 형태를 몰랐습니다. 세 가지 모두 "자동화가 이 케이스를 놓칠 수 있다"는 걸 사전에 안 게 아니라, 실제로 놓친 뒤에야 알았습니다. 일반화하면 완전자동을 목표로 설계할수록,

Making something run automatically and having it actually get handled to completion turned out to be two different sentences This is the English version of a post originally written in Korean for my algorithmic trading system devlog (new tab). I designed this system to judge and trade on its own, without needing human approval for each decision. The order execution and safety-guard layer (new tab) was built around that same goal. Over the past month, though, there were three separate moments where I had to step in and act directly on the live account. Each one failed for a structurally different reason. 1. An allocation rule structurally starved one order I noticed a particular ticker had a sell plan queued for several days running, yet it never actually went out. The system kept nominating it as a sell candidate every day, but the order never reached execution. The cause was the rule that splits the daily trading budget across multiple rounds. This position's order size was consistently larger than whatever sell budget remained that day. No matter how the rounds were reordered, it could never clear. The budget cap itself was working exactly as designed. The problem was that the underlying assumption — "if it doesn't clear this time, it'll clear next time" — never held for this position. New opportunities kept arriving, but none of them was ever big enough. I executed the one blocked order by hand. It was an irreversible sell on the live account. Afterward, I reworked the allocation rule itself so the same starvation pattern couldn't recur. 2. A safety guard confused a snapshot with a cumulative reading On a different day, the opposite kind of failure happened. A guard meant to detect cumulative drawdown wrongly blocked two legitimate buy orders. The index was nearly flat that day, but the loss figure this guard was tracking read much larger. Looking closer, the guard was designed to measure "decline from peak," but the current value it compared against was an intra

로그조차 안 쌓이니, 돌고 있는지 죽어 있는지 구분할 방법이 없었습니다 이 블로그의 개발일지는 매일 밤 자동으로 마무리됩니다. 그날 대화로 초안을 썼으면 변환해서 로그에 남기고, 없으면 스킵했다는 한 줄만 남깁니다. 최근 이 파이프라인을 들여다볼 일이 있었는데, 7월 24일 이후로 로그가 통째로 비어 있었습니다. 무슨 일이 있었나 자동화 로그( .automation.log ) 마지막 줄이 2026-07-24였습니다. 그 뒤로 8월 22일까지, 거의 한 달 가까이 스킵 기록조차 한 줄도 없었습니다. 자동화가 아예 안 돌았나 싶어서 실행 로그( cron_output.log )를 열어봤습니다. 그런데 거기엔 매일 밤 실행된 흔적이 빼곡했습니다. 날짜 확인하고, 초안 있으면 내용 정리하고, 크로스링크까지 챙긴 요약이 매일 밤 남아 있었습니다. 일은 하고 있었는데, 결과물만 하나도 남지 않고 있었던 겁니다. 왜 아무도 몰랐나 실행 로그를 읽어보니 원인은 매일 같았습니다. 파일 쓰기 권한 승인을 기다리다가 그대로 끝난 겁니다. "workspace has not been trusted"라는 경고가 매 실행마다 찍혀 있었습니다. 초안을 잘 정리해놓고도, 마지막 파일 쓰기 한 줄이 승인 대기에 막혀서 아무것도 저장되지 않은 채 세션이 끝나는 패턴이 한 달 가까이 반복됐습니다. 문제는 이게 하필 로그를 남기는 단계 자체가 막힌 상황 이었다는 겁니다. 스킵한 날엔 스킵했다는 한 줄도 못 남겼습니다. 그러니 로그만 보면 "자동화가 멈췄다"와 "쓸 게 없어서 조용했다"를 구분할 수가 없었습니다. 무인 자동화이니 매일 밤 누가 화면을 지켜보는 것도 아닙니다. 결과적으로 이 공백은 사람이 우연히 로그 파일을 열어보기 전까지는 발견될 방법이 없는 구조였습니다. 진짜 원인 원인은 신뢰(trust) 설정이었습니다. 이 헤드리스 자동화 세션은 프로젝트 폴더 단위로 파일 쓰기 권한을 신뢰받아야 동작하는데, 그 신뢰 설정 키가 이 블로그 폴더가 아니라 상위 디렉터리(프로젝트들이 모여 있는 루트) 단위로 걸려 있었습니다. 즉 이 블로그 폴더만 놓고 보면 "아직 한 번도 대화형으로 신뢰 승인을 받은 적 없는 새 작업공간" 취급을 받고 있었던 셈입니다. 설정 파일 안에 이미 허용 규칙 10개가 들어 있었는데도, 그 규칙들이 걸려 있는 범위 자체가 무시되고 있었습니다. 헤드리스로 도는 야간 자동화는 대화형 승인 프롬프트에 응답할 사람이 없습니다. 범위가 어긋난 신뢰 설정 하나가, 매일 밤 정확히 같은 지점에서 조용히 실행을 무력화하고 있었던 겁니다. 흥미로운 디테일 하나 — 유령 완료 기록 이 공백을 되짚어보다가 특이한 줄 하나를 발견했습니다. 8월 22일 낮 12시 41분에 "weekly: 완료"라는 로그 한 줄이 남아 있었는데, 그 시각에 대응하는 실제 산출물 파일은 없었습니다. 같은 날 오후 4시에 다시 수동으로 실행된 기록이 있었고, 이번엔 실제 파일까지 정상적으로 만들어졌습니다. 앞선 12시 41분 기록이 왜 실물 없이 "완료"라고만 남았는지는 원인을 특정하지 못했습니다. 권한 문제가 한창이던 구간이라 어떤 형태로든 쓰기 절차 일부만 성공하고 일부는 실패한 걸로 추정만 할 뿐입니다. 다만 이 한 줄은 별도로 눈에 띄는 교훈을 남겼습니다. "완료"라고 적힌 로그도 그 자체로 완전히 믿을 수는 없다 는 겁니다. 로그와 실제 산출물을 따로 대조하지 않았다면 이 유령 기록을 그냥 지나쳤을 겁니다. 어떻게 고쳤나 신뢰 설정을 이 블로그 폴더 기준으로 다시 걸어주니, 그날 밤부터 바로 정상화됐습니다. 별도의 복잡한 조치는 필요 없었습니다. 문제는 고치는 방법이 아니라, 한 달 가까이 그 문제를 놓치고 있었다는 사실 쪽이었습니다. 일반화된 교훈 이번 일로 다시 확인한 건, 무인 자동화에서 "로그가 없다"는 상태 자체가 하나의 신호라는 겁니다. 그런데 그 신호를 신호로 취급하려면, 애초에 "침묵"과 "성공적인 무동작"을 구분할 수 있게 설계돼 있어야 합니다. 이번 파이프라인은 스킵한 날에도 로그 한 줄을 남기게 되어 있었습니다. 그 설계 덕분에, "로그가 아예 안

This is good : Post-quantum cryptography is now one pip-install away for the entire Python ecosystem. With funding from the Sovereign Tech Agency , we implemented support for ML-KEM, the NIST-standard key-establishment primitive, and ML-DSA, the NIST-standard digital-signature primitive, in pyca/cryptography. Remember, the reason to do this now is because there’s no emergency. And because you will make your systems crypto agile, which is always a good idea.

Zulfi Alam thinks his team doesn’t need to “prove” they engineered a new state of matter in their bid to reinvent computing. Science would disagree.

A portfolio can look good on the usual scorecard and still answer the wrong question. One line says return was high. Another says risk-adjusted performance was acceptable. A third says drawdown stayed inside a tolerable range. Then the market turns, the benchmark starts recovering, and the thing I actually care about is different: how efficiently did the portfolio catch up? That is where a new metric can fool its own author. If I build a recovery measure and it moves almost exactly like an existing ratio, I have created a longer name for the same signal. The right acceptance test is geometric: a useful metric should cast a different shadow. This is the rule I used while validating Hyperlogarithmic Benchmark Catch-Up Ratio (HBCR): orthogonality to existing measures is a first-class test, not a chart for the appendix. 1. A new metric has to earn its axis HBCR was built to measure benchmark-relative recovery dynamics. The research page states the motivation plainly: traditional benchmark-relative metrics often fail to capture the true dynamics of investment performance, especially during market recoveries [ A New Metric for Private Equity Risk Adjusted Returns , Calibration of Risk and Correlation in Private Equity ]. That framing matters because the obvious validation path is tempting and weak. You compare the new number with familiar performance measures, find a comforting relationship, and declare victory. But a high correlation with a well-known score can be a warning. If HBCR strongly tracked Sharpe Ratio, it would probably be an expensive synonym for risk-adjusted return. The acceptance test I wanted was sharper. HBCR should have some relationship with performance, because recovery has economic content. It should also avoid collapsing into the same direction as Sharpe Ratio, Beta, Volatility, Alpha, Total Return, or Max Drawdown. Written as a predicate, the test has two sides. Let $\mathcal{T}$ be the set of metrics already on the scorecard, $\rho_{n,m}$ the corr

Una discusión sobre un archivo digital casi nunca se pierde por lo que el archivo dice. Se pierde una pregunta antes: ¿Cómo sabemos que ese es el archivo que usted recibió, y no el que editó anoche? Si la respuesta es "confíe en mí", ya perdiste. Y da igual cuánta razón tengas en el fondo. Este problema no es exclusivo de un juzgado. Lo tiene el auditor que recibe un volcado de logs, el equipo que documenta un incidente, quien conserva la copia de un contrato firmado por correo. En todos los casos hace falta lo mismo: poder demostrar que un conjunto de bytes no cambió desde un momento determinado, y que lo demuestre alguien que no seas tú . Para eso escribí Tunjo : una herramienta en Rust que recorre un material en solo lectura, calcula su huella y firma un acta verificable por cualquiera. Por qué un árbol y no un hash Lo obvio sería concatenar todo y sacar un SHA-256. Funciona, y es inútil en la práctica. Cuando alguien discute un archivo —un correo concreto entre cuatro mil— con un hash único solo puedes ofrecer dos cosas: o entregas el conjunto completo para que se recalcule, o pides que te crean. La primera opción expone material que no tiene por qué exponerse; la segunda no es una prueba. Un árbol de Merkle resuelve exactamente eso. Cada archivo es una hoja, cada par de nodos se combina hacia arriba y queda una raíz. Para demostrar que una hoja pertenece a esa raíz basta con exhibir esa hoja y el camino de hashes hasta arriba: unos pocos kilobytes. El resto del conjunto no se toca. Dos detalles del árbol que no son opcionales: // Separación de dominio: una hoja nunca puede hacerse pasar por nodo interno. h . update ([ 0x00 ]); // hoja h . update ([ 0x01 ]); // nodo interno // Y la raíz ata el número de hojas. h . update ([ 0x02 ]); h . update ( n . to_be_bytes ()); Sin lo primero, un hash de hoja podría presentarse como si fuera un nodo del árbol. Sin lo segundo aparece la ambigüedad clásica de los árboles con número impar de hojas: dos conjuntos distintos pued

We live in an era where our wrists track every heartbeat, step, and sleep cycle. Yet, most of this "Quantified Self" data sits rotting in massive .xml or .json export files that are impossible to read. What if you could simply ask your AI, "How did my resting heart rate trend during the week I was stressed about the product launch?" In this tutorial, we are building a Quantified Self RAG (Retrieval-Augmented Generation) pipeline . We will take fragmented health data from Apple HealthKit and Google Health Connect, process it using DuckDB , and vectorize it into Pinecone using LangChain . By the end of this guide, you’ll have a production-grade Health Data RAG system capable of high-performance natural language queries over your personal biometrics. The Architecture: From Raw Logs to Vector Insights Handling health data at scale requires a robust ETL (Extract, Transform, Load) process. Vectorizing every single heart rate measurement (which can occur every few seconds) is inefficient and expensive. We need to downsample and summarize before embedding. graph TD A[Apple Health/Google Health] -->|Export XML/JSON| B[Raw Data Storage] B --> C{DuckDB Processing} C -->|Cleaning & Downsampling| D[Structured Parquet/JSON] D --> E[LangChain Document Loader] E --> F[OpenAI Embeddings] F --> G[Pinecone Vector Database] H[User: 'Why was my sleep poor last Tuesday?'] --> I[LangChain RAG Chain] G --> I I --> J[LLM Contextual Answer] Prerequisites 🛠️ To follow along, you'll need: Python 3.10+ Tech Stack : Pinecone , LangChain , DuckDB , OpenAI , and Pandas .

When engineers discuss quantum computing, the conversation usually focuses on future supercomputers cracking traditional encryption passwords in a matter of seconds. As a systems architect who spends my days building distributed platforms, which are networks of independent cloud servers working together as a single application, I see a different, highly practical challenge taking shape. The transition to quantum-resistant security is not simply a theoretical math problem. It is an infrastructure challenge that will directly impact network throughput, memory usage, and messaging efficiency across global cloud environments. To protect sensitive enterprise records and business platforms against future quantum threats, security organizations are transitioning to Post-Quantum Cryptography. This field involves building new mathematical algorithms that quantum computers cannot easily solve. However, these stronger defense mechanisms come with a major trade-off in size. Traditional cryptographic signatures, which are digital verification stamps used to prove that a data message comes from an authentic sender and was not altered, are remarkably small. An older, standard signature might only take up sixty bytes of memory. By comparison, a quantum-safe signature can easily require several thousand bytes. In a simple website, adding a few extra kilobytes to a security header goes unnoticed. But modern cloud infrastructure relies heavily on event-driven architecture, a design strategy where dozens of microservices communicate by constantly publishing tiny, real-time updates to shared message queues. In these systems, the actual business payload might only be a small status change containing twenty bytes of text. If the quantum security stamp attached to that message is three thousand bytes, the overhead of the security layer completely outweighs the actual data being sent. When security footprints expand by orders of magnitude, the physical realities of computer networking take

Probabilistic Graph Neural Inference for bio-inspired soft robotics maintenance with ethical auditability baked in I remember the moment it clicked. I was hunched over a workbench in my home lab, staring at a tangled mess of silicone tentacles—a soft robotic octopus arm I’d 3D-printed and embedded with pneumatic channels. The arm was supposed to mimic the graceful, adaptive movements of a real cephalopod, but after a few cycles, it had developed a slow leak at one of the joint interfaces. The pressure sensors were giving erratic readings, and my traditional rule-based diagnostic script was useless. I’d spent weeks training a simple neural network to detect anomalies, but it kept flagging benign sensor noise as critical failures. That’s when I stumbled upon a paper on probabilistic graph neural networks (PGNNs) for molecular dynamics, and I realized: soft robotics maintenance isn’t about deterministic predictions—it’s about reasoning under uncertainty over a complex, interconnected system. This article is the story of how I built a PGNN-based inference system for bio-inspired soft robots, with ethical auditability baked in from the ground up. Technical Background: Why Soft Robotics Needs Probabilistic Graph Inference Soft robotics is fundamentally different from rigid robotics. A rigid arm has well-defined joints, links, and sensors; failures are often binary (motor burnout, gear slip). But a soft robotic tentacle is a continuum of deformable material with distributed sensing and actuation. The system’s state is a high-dimensional, partially observable probability distribution over material strains, pressures, and temperatures. Traditional diagnostic models—like support vector machines or feedforward neural networks—treat each sensor as an independent feature, ignoring the spatial and temporal dependencies that define soft robot behavior. In my research of graph neural networks, I realized that a soft robot is naturally a graph: each sensor node (pressure, strain, te

Introduction Having laid out some mathematical foundations in the [previous part][1], we will proceed to discuss quantum gates and circuits in depth here. As usual, we will drive home the theories with worked examples from [@Rieffel2011] and check their accuracy with qiskit and/or cirq code. Prerequisite Understanding quantum gates and circuits will be greatly aided by the knowledge of classical gates (AND, OR, NOT, XOR and the universal gates: NAND and NOR). Also, some familiarity with the Python programming language will help you understand qiskit and/or cirq code. Classical & Quantum gates A classical computer, possibly the one you're reading this with, is a sophisticated engineering piece, no doubt. However, the underlying "magic" comprises logic gates. The National Institute of Standards and Technology (NIST) gives this incredible analogical description of classical computers in relation to logic gates [@NISTQGATE2026]: Traditional computers are like microscopic cities. The roads of these cities are wires with electricity coursing through them. These roads have lots of gates, known as logic gates, which enable computers to do their job. Like physical gates that allow or block cars, logic gates allow or block electricity. Electricity that goes through the gates represents a “1” of digital data, and blocked electricity is a “0.” When you pick up a motherboard, for instance, you may not see the said gates as they are made of tiny transistors (in modern systems, MOSFETs) in specific combinations. Also, the $0$ and $1$ referred to in the analogy mean low and high voltage ranges, respectively. Their actual voltage values depend on the hardware. :::note All schematics were written in and rendered by @schemd/core . Check it out. ::: Logic Gates refresher Since we will be realizing some classical circuits using quantum gates, it's necessary to get familiar with common logic gates. NOT ($\neg$) Gate This gate takes a single classical bit and flips it. For instance, if $0

Like its U.S. counterpart, the European Chips Act aims to foster the semiconductor industry — in part thanks to state subsidies. One of the beneficiaries is QuantumDiamonds, a German startup that applies a novel approach to inspecting chips.

France is accelerating its transition to post-quantum encryption: France’s cybersecurity agency ANSSI said on Tuesday it would stop certifying security products that lack quantum-resistant encryption, a move that will force government bodies and critical operators to shift away from older systems. Samih Souissi, ANSSI’s chief of staff, said at the France Quantum conference that the agency would halt such certifications from 2027, and that businesses should be buying only quantum-safe products by 2030. ANSSI approval is required for use in French government agencies and critical infrastructure, making the policy a de facto phase-out of older encryption...

[Excerpted from THE QUANTUM COLLAPSE CHRONICLES — not science fiction, but a grounded forecast of what may come when quantum computation dismantles the cryptographic foundations of our digital civilization. These articles explore the collapse of computational trust and the brutal reconstruction of the world that follows.] The history of human civilization is often defined by sudden, violent shifts in the nature of power. We speak of the fall of empires, the industrial revolutions, and the splitting of the atom. But in the mid-2030s, the world experienced a collapse that was not made of steel or stone, but of mathematics. It was a quiet, clinical, and utterly devastating unraveling of the digital fabric that held modern society together. To understand The Quantum Collapse , one must look past the headlines of the era and into the humming, sub-Kelvin depths of the dilution refrigerators that changed everything. This is the story of how the transition from probabilistic experimentation to deterministic computation rendered the world's secrets transparent and its economies obsolete. The Death of Noise: The Rise of Dr. Aris Thorne For the first three decades of the 21st century, quantum computing was a game of chance. Scientists operated in the era of Noisy Intermediate-Scale Quantum (NISQ) devices—machines so temperamental and prone to error that every calculation was a desperate struggle against environmental noise. In those days, a single stray photon or a microscopic fluctuation in temperature could collapse a delicate superposition, turning a groundbreaking calculation into useless digital static. The turning point arrived in 2036 at the Institute for Advanced Quantum Engineering (IAQE) in the High Sierras. The air in the facility didn't vibrate with the erratic drone of the late 2020s; instead, it carried a heavy, rhythmic thrum—the sonic signature of the Lattice-Array-9 (LA-9). At the center of this revolution was Dr. Aris Thorne, the lead architect of the LA-9 pr
