If you've ever tried integrating a large language model (LLM) into a Java application, you've probably written a lot of boilerplate: HTTP clients, JSON parsing, streaming handling, session management. Solon 4.0's ChatModel abstracts all of that away with a clean, builder-oriented API. In this guide, I'll walk through building real, working AI features using ChatModel — from a simple chat call to a streaming chatbot with conversation memory. 1. What Is ChatModel? ChatModel (package org.noear.solon.ai.chat ) is a unified LLM client in Solon's AI ecosystem. Instead of writing raw HTTP calls for different model providers, you use a single API that supports: Synchronous calls — one-shot request, full response Streaming calls — reactive streaming via Project Reactor ( Flux<ChatResponse> ) Tool/Function Calling — let the LLM invoke your Java methods Chat Sessions — automatic conversation memory Multi-modal messages — text, images, audio Dialect adaptation — works with OpenAI, Ollama, Anthropic, Gemini, DashScope, and more The best part? It uses a dialect pattern — you point it at any compatible LLM endpoint, and it adapts automatically. 2. Setting Up Add the dependency to your pom.xml (no parent POM needed — Solon works standalone): <dependency> <groupId> org.noear </groupId> <artifactId> solon-ai </artifactId> <version> ${solon.version} </version> </dependency> This pulls in all built-in dialects (OpenAI, Ollama, Gemini, Anthropic, DashScope). 3. Configuration 3.1 Via YAML (Recommended) solon.ai.chat : demo : apiUrl : " http://127.0.0.1:11434/api/chat" # Full URL, not baseUrl provider : " ollama" # Dialect identifier model : " llama3.2" # Model name headers : x-demo : " demo1" Then create a @Bean to get a ready-to-use ChatModel : import org.noear.solon.ai.chat.ChatConfig ; import org.noear.solon.ai.chat.ChatModel ; import org.noear.solon.annotation.Bean ; import org.noear.solon.annotation.Configuration ; import org.noear.solon.annotation.Inject ; @Configuration public cla

Hey dev community! I don't have a PC yet, so I challenged myself to build an open source ethical hacking & "security audit" tool called ImCurvin' completely on my phone screen. Here is my honest background: I just started learning programming 6 months ago (yes, January 2026!). Since then, I've been fully focused on coding. Just 2 weeks ago, I decided to jump into cybersecurity. To be honest, I hate memorizing dry theories. I prefer focusing purely on the logic and finding cracks in systems. While I am a bit lazy with documentation, I am doing my best to learn all the official "technical terms" along the way! The project currently stands around 1,155 lines of code (993 Bash, 162 Python), i want it to be minimalist. The tool is fully modularized with separate payload directories, though the overall formatting might look a bit messy since every single character was typed on a smartphone touch screen. I want to keep this post super short, so please check out the full features, code documentation, and contribution guidelines directly inside my repository: Check out https://github.com/Skokoo/ImCurvin Feel free to check it out, and please submit a Pull Request or open an issue if you want to help a beginner clean up and optimize the code!

Half a year ago, I wanted to see for myself what can we currently have with local LLMs. I went down the rabbit hole, learned quite a lot in the process, and shared my results in an article . The results were pretty discouraging: even with 32 GB VRAM, the best models I could run were both too slow and too dumb. At the same time, what you could get for free from inference providers was actually decent - and much faster. I remember my conclusion: "Let's wait for the next generation of models, which looks very promising. If we can run something comparable to full-size Qwen3-Coder-480B locally, that would be year of the Linux Desktop age of fully capable local LLMs. And now this day has arrived. Models Half a year later, I'm revisiting this question. And this time, the whole situation has turned upside-down. Almost none of the providers still have free tier, and anything that's still free is barely good enough even for the simplest tasks. And is rate-limited all over. And on the local side, the next Qwen lineup is out. So, that's what I'm going to be looking at. Once again, I have two RX6800's, 16 GB each, and 64 GB RAM. On one hand, this is more VRAM than any "normal person" can have with one GPU - unless you've got something specifically for AI, like an unified-memory Mac or a DGX Spark. On the other hand, RX6800 is "pre-AI" - anything newer will have much better performance thanks to tensor processors. Qwen3.6-27B : This is a dense model, so basically you can't run it at all on anything less than 32 GB VRAM. It's the slowest one, but also the best one if you can run it. Its accuracy is claimed to be on par with Claude 4.5 Opus, and better than Qwen3.5-397B-A17B . This is what I've been waiting for. It runs reasonably fast on my setup, so it's very much usable both in terms of performance and accuracy. Qwen3.6-35B-A3B : This one is MoE, and it's pretty small, so it's the fastest one. It's good for anything that doesn't require too much (i.e. for agentic tasks that don'

GitHub said this week that Copilot CLI, when it runs inside a GitHub Actions workflow, will accept the built-in GITHUB_TOKEN for authentication. Per the July 2 changelog, the previous path required creating and storing a personal access token. The operational read is small and precise: one fewer human-owned credential to mint, rotate and inherit. The exact scope of the change The changelog covers a narrow surface. It applies to Copilot CLI when invoked from a GitHub Actions workflow, and it swaps the required credential from a PAT to the workflow's ambient GITHUB_TOKEN . GitHub does not describe changes to how Copilot CLI authenticates outside Actions, and this post will not extrapolate to those contexts. If your Copilot CLI usage lives on a developer laptop or in another CI system, nothing in this announcement moves for you. Why the PAT was the wrong credential to leave in the loop A personal access token has almost none of the properties you would want from an automation credential. It does not expire on a job boundary. It carries a person's identity, not the workflow's. It sits in Actions secrets long enough to outlive the engineer who created it. And its scopes were chosen by that engineer, at that moment, often wider than the job actually needs. GITHUB_TOKEN is the opposite shape. Actions mints it at the start of a job, scopes it through the workflow's permissions: block, and revokes it when the job ends. If the token leaks, the window for abuse is the runtime of the job, not the years until somebody remembers to rotate it. When the person who wrote the workflow leaves, the pipeline does not silently break because a token expired with their account. For scripted Copilot CLI calls that had to be wrapped in a PAT, that is the whole win. The tool authenticates against the workflow instead of against a human. Wiring it up The workflow-side pattern is the same one every GITHUB_TOKEN -consuming step already follows: declare permissions: explicitly at the job level, k

We’ve all been there. You start your morning feeling like a Productivity God, sitting straight and typing at 120 WPM. Fast forward four hours, and you've morphed into a literal shrimp, face inches away from the monitor, hunting for a missing semicolon. 🦐 In this era of remote work, real-time posture correction and computer vision for health have become more than just "cool projects"—they are spinal lifesavers. Today, we’re going to build a desktop application using MediaPipe , WebRTC , and Electron that monitors your neck angle and sends a desktop notification the moment you start slouching. By leveraging MediaPipe Pose and TensorFlow.js , we can calculate the Forward Head Posture (FHP) ratio with surgical precision directly in the browser environment. The Architecture 🏗️ Before we dive into the code, let’s look at how the data flows from your webcam to that "Sit up straight!" notification. graph TD A[Webcam Feed] -->|MediaStream| B(WebRTC API) B -->|Video Frames| C[MediaPipe Pose Model] C -->|Landmarks| D{Geometry Engine} D -->|Calculate Ear-Shoulder Angle| E{Threshold Check} E -->|Angle > 30°| F[Electron Main Process] F -->|Trigger| G[System Desktop Notification] E -->|Healthy| H[Continue Monitoring] style G fill:#f96,stroke:#333,stroke-width:2px Prerequisites 🛠️ To follow along, you'll need the following tech stack: MediaPipe Pose : For high-fidelity body tracking. WebRTC : To capture the video stream from your webcam. Electron : To wrap our logic into a desktop app that runs in the background. TensorFlow.js : The backbone for running ML models in JavaScript. Step 1: Setting up the Video Stream (WebRTC) First, we need to grab the camera feed. In a modern browser environment (or Electron's Chromium), we use navigator.mediaDevices.getUserMedia . async function setupCamera () { const videoElement = document . getElementById ( ' input_video ' ); const stream = await navigator . mediaDevices . getUserMedia ({ video : { width : 640 , height : 480 }, audio : false }); v

If you've ever built a feature that extracts text from PDFs, an Arabic-speaking user has probably filed this bug: "the words come out in reverse order." Not the letters — the words . Every line reads last-word-first. I spent the better part of a year fixing this class of bugs while building Confileo , a free PDF toolkit with first-class Arabic support. Here's what's actually going on, because almost every explanation online is wrong or incomplete. The four distinct failure modes People say "Arabic breaks" as if it's one bug. It's four: 1. Visual vs logical order (the reversed-words bug) A PDF doesn't store text the way a Word file does — it stores positioned glyph runs : "paint these shapes at these coordinates." For left-to-right scripts, the paint order happens to match the reading order, so naive extraction works by accident. Arabic is right-to-left. Many PDF generators emit the glyph runs in visual order — the order they appear on screen, left to right. A naive extractor concatenates the runs as stored and produces every line word-reversed. The text was never "reversed" in the file; your extractor just assumed paint order == reading order. Fix: reconstruct logical order using glyph positions + the Unicode Bidirectional Algorithm (UAX #9), not the content-stream order. Libraries like PyMuPDF already return text in logical order — a common mistake is "fixing" that output by reversing it again, which is how you get double-reversed text. Rule of thumb: never reverse Arabic yourself. If it looks backwards, your rendering layer lacks bidi support; the data is usually fine. 2. Disconnected letters (the ransom-note bug) Arabic letters are contextual: ع renders differently in initial, medial, final and isolated positions, and letters join. That joining is applied at render time by a shaping engine (HarfBuzz being the standard). If any step of your pipeline round-trips text through a non-shaping renderer — a canvas library, a barebones PDF writer, an image caption filter

In production we have ~1.5 TB of full-text court decisions and their vector embeddings, plus another ~550 GB of other legal data: registries, legislation, business entities, a Spanish case law corpus, EU-Lex. If we take this corpus and train an MoE model the size of DeepSeek V3, scaled to 860B parameters, on GCP — what comes out? We break down the dataset, architecture, compute cost, and the properties such a model would have on Ukrainian law. What's in the Dataset The entire corpus is what's already running in SecondLayer's production. No extra scrapes, no Common Crawl, no noise. EDRSR — the dataset core, ~1.5 TB. The Unified State Register of Court Decisions of Ukraine. 96.2 million full-text decisions (1,079 GB in PostgreSQL TOAST), 471 GB of vectors in Qdrant (voyage-3.5, 1024-dim), 28 GB of metadata (court, judge, date, case category, proceeding type, statute code). Breakdown by jurisdiction: civil 33.7M, administrative 14M+, criminal 12M+, commercial 6M+, misdemeanors 6M+. Largest annual cohort — 2024 (115 GB of TOAST text). OpenReyestr — 43 GB. Ukrainian public registries: 16.7M legal entities (EDR), ownership structures (beneficiaries, shareholders), debtors (State Enforcement Service), NAIS registries. This is the foundation for SneakyPiper — our due-diligence platform — but here it serves as raw corpus for the model. Legislation — ~40 GB. The Constitution, major codes (Civil, Criminal, Criminal Procedure, Civil Procedure, Commercial Procedure, Administrative Procedure, Labor, Tax, Customs), laws, and secondary legislation. All structurally annotated: articles, parts, clauses, revision dates with effective-date tracking. This isn't flat text: we know that Article 124 of the Constitution took effect on a specific date, carries particular references, and is cited in a precise number of decisions. Supreme Court review practices + lu_court_decisions — ~25 GB. SC plenary decisions, practice overviews, Grand Chamber rulings. This is the most valuable slice — the

I build and run one of the tools on this list (AGenO — full disclosure below), and I use every other tool here regularly. This is what "free" actually gets you on each one, including the catches. The AI tool landscape has a dirty secret: almost nothing labeled "free" is free. Most tools give you a taste — ten messages, three images, one song — and then the paywall lands. So instead of another list of forty tools nobody has tried, here are nine that give you real value at $0, organized by what you're trying to make, with the actual limits spelled out. Quick comparison Tool Best for What's actually free The catch ChatGPT General chat & writing ~10 msgs/5h on the flagship model Silently switches you to a weaker model after the limit Claude Long documents, nuanced writing 10–25 msgs/5h, varies with demand Limits shrink when servers are busy Gemini Image generation & editing Generous with a Google account Best features drift to the paid tier Perplexity Research with citations Unlimited basic searches Pro searches are capped Suno AI music ~10 songs/day No commercial use on free; failed generations can eat credits Leonardo AI Stylized art & game assets Daily token allowance Confusing token system; images are public on free Character.AI Roleplay & AI characters Unlimited chat Heavy filters; your chats train their models AGenO All of it in one place Images, songs with vocals, chat, characters, stories, coding problems — daily free allowance One-person project — busy hours can mean a short queue Canva Magic tools Quick social graphics 50 text-to-image uses Design-tool add-on, not a real generator Chat and writing ChatGPT is still the default for a reason — the free tier includes the flagship model and it's good at nearly everything. The catch nobody tells you about: after roughly ten messages in five hours, it quietly downgrades you to a mini model without making it obvious. If your answers suddenly get dumber mid-conversation, that's why. Claude writes the most natural prose

Google Trends has no official API, and most wrapper libraries rot within months. But the Trends site itself runs on a keyless JSON API that anyone can call, and it serves the exact numbers you see in the UI. Here is the full recipe, including one gotcha where Google quietly labels your session a scraper. The two step flow Trends works in two steps. First you call explore , which returns a list of widgets, one per chart on the page, each with a signed token: GET https://trends.google.com/trends/api/explore ?hl=en-US&tz=0 &req={"comparisonItem":[{"keyword":"web scraping","geo":"US","time":"today 12-m"}],"category":0,"property":""} Then you call a widget data endpoint with that widget's request and token : GET https://trends.google.com/trends/api/widgetdata/multiline?hl=en-US&tz=0&req=<widget.request>&token=<widget.token> The widget kinds map to endpoints: TIMESERIES uses multiline , GEO_MAP uses comparedgeo , and both RELATED_QUERIES and RELATED_TOPICS use relatedsearches . The cookie trick Call explore cold and you get a 429. The API wants a NID cookie, and here is the counterintuitive part: you get it by requesting the public explore page first, and that page may itself respond 429 while still setting the cookie you need. const res = await fetch ( ' https://trends.google.com/trends/explore?geo=US&q=test ' ); // res.status may be 429. The Set-Cookie header is still there. const cookies = res . headers . getSetCookie (); Grab the cookie from the 429 response, retry explore , and everything works. Strip the anti JSON prefix Every Trends response starts with a junk line like )]}' to break naive JSON.parse calls. Drop everything up to the first newline: const body = await res . text (); const data = JSON . parse ( body . slice ( body . indexOf ( ' \n ' ) + 1 )); The scraper flag Here is the part I have not seen documented. Look inside the widget request object that explore returns to a keyless session: "userConfig" : { "userType" : "USER_TYPE_SCRAPER" } Google knows. And

Hi everyone, I want to share textparser, a high-performance, lightweight text parsing and AST generation library written in pure C. 💡 The Core Idea & Why It's DifferentTraditional parser generators (like Flex/Bison) come with a steep learning curve and rigid code generation. On the other end, hand-writing recursive descent parsers or state machines becomes an unmaintainable mess as your language grows.textparser bridges this gap using a hybrid JSON + Python + C workflow:You define your tokens, syntax patterns, and color styles in a clean, human-readable JSON grammar file. A lightweight Python compiler tool processes the JSON, runs optimizations, and emits a dense, static C header array.The C runtime engine loads these pre-compiled arrays instantly. It processes raw text strings into an abstract token tree (textparser_token_item) using a highly optimized regular expression engine (crpe2).By offloading the grammar overhead and heavy state-machine parsing logic to the Python build step, the actual runtime C library stays incredibly lean, memory-efficient, and fast. 🚀 Features At A Glance30+ Languages Out-of-the-Box: Includes ready-to-use JSON grammars for C, C++, Rust, Python, JavaScript, HTML, SQL, and dozens more.Rich Token Metadata: Every parsed token tracks exact code coordinates, structural flags, and custom syntax styling options.Zero Bloat: Ideal for terminal text editors, syntax highlighters, custom linters, and lightweight static analysis tools where bringing in a massive compiler front-end is overkill.

There's a phase almost every developer gets stuck in. You're consuming tutorials, bookmarking articles, finishing courses, and buying books you'll read "eventually." You're learning constantly — but you're not producing anything. You're just... absorbing. That's the learning vacuum. And if you've been there, you know how easy it is to confuse staying busy with making progress. At some point, the shift has to happen. You stop being a sponge and start being a signal. Here's how I started making that turn. Start a Daily or Weekly Code Journal You don't need a blog, a brand, or an audience for this. Just a file. A note. Anything. Write down what you built, what broke, and what you figured out. Even one sentence counts. I like to write a quick sentence and how many hours, just like if you were filling in an invoice for contract work. The act of putting it into words forces you to actually process what you learned instead of letting it blur into the background noise of your brain. Over time, those entries start to look like a roadmap — and you realize you've come further than you thought. Code Something You Actually Want to Build Pick something dumb. Pick something fun. A browser game, a weird UI experiment, a tool that solves exactly one tiny problem in your life. I signed up for DEV Challenges , Summer Bug Challenge and upcoming Weekend Challenge to get my ball rolling. The best projects I've ever worked on had no real-world utility. They were just interesting to me. And that interest kept me showing up even when things got hard. A tutorial can't give you that. Only a project you actually care about can. Find Your People Whether it's here or a Discord server, a local meetup, a dev community on Farcaster or Lens, or just a forum thread you keep coming back to — find somewhere to show up regularly. Lurking is fine at first. But eventually, drop a comment. Answer a question you know the answer to. Share something you built. Community is where isolated learning becomes shar

Every business that has ever typed a web address into a browser owes a small debt to a company most people have never heard of. On March 15, 1985, a computer maker called Symbolics registered Symbolics.com and, in doing so, became the first ever holder of a .com domain name. More than forty years later that address is still registered and still resolves - making it the oldest .com domain on the internet. Who was Symbolics? Symbolics Inc. was a Massachusetts company that built specialized computers called Lisp machines - workstations designed from the silicon up to run the Lisp programming language, then the darling of artificial intelligence research. These were serious, expensive machines aimed at labs and universities, and the company sat right at the cutting edge of 1980s computing. So it was fitting, if a little accidental, that they were first in line when commercial domains became available. The domain name system itself was brand new. DNS had only been introduced in 1983 to replace the unwieldy HOSTS.TXT file that every machine on the early internet had to keep in sync. The now-familiar top-level domains - .com , .org , .net , .edu , .gov - were defined in 1984. When registration opened, .com was meant for commercial entities, and Symbolics grabbed theirs before anyone else did. A slow start for the web's most valuable real estate What is striking today is how little demand there was. In the whole of 1985, only a handful of .com domains were registered - names like BBN, Think, and a few other technology companies trickled in over the following months. There was no gold rush, because there was no web yet. Tim Berners-Lee would not propose the World Wide Web until 1989, and the first website would not appear until 1991. A domain name in 1985 was a technical convenience for reaching a machine, not a brand or a piece of property. That makes Symbolics.com a kind of time capsule. It was registered before the web, before browsers, before e-commerce, and before anyon

AI agents are only as smart as the context you give them. OKF is a new open specification that packages your organizational knowledge as plain markdown files so any agent can read it without custom integrations or proprietary SDKs. Every team building AI agents hits the same wall. The model is capable. The agent framework is set up. But the agent doesn't know anything about your organization. It doesn't know what your orders table means, what the churn_score metric formula is, or what the on-call runbook says to do when the pipeline breaks. That knowledge exists. It's scattered across Confluence pages, Notion wikis, data catalog entries, Slack threads, and the heads of senior engineers. Getting it into an agent means building a custom integration for every source. Every team solves this from scratch. Published on June 12, 2026, the Open Knowledge Format (OKF) is a vendor-neutral specification that solves this with the simplest possible approach: a directory of markdown files. 🎯 🏗️ What OKF Actually Is An OKF bundle is a directory of markdown files representing concepts: anything you want to capture, including tables, datasets, metrics, playbooks, runbooks, and APIs. Each concept is one file. That's the entire model. A directory of .md files with YAML frontmatter. The format is deliberately minimal: one required field ( type ), optional metadata ( title , description , resource , tags , timestamp ), and a free-form markdown body. A concept document looks like this: --- type : table title : " orders" description : " One row per customer order. Source of truth for revenue reporting." resource : " postgresql://prod-db/ecommerce/orders" tags : [ revenue , core , sla ] timestamp : 2026-06-15T10:00:00Z --- # orders The `orders` table records every purchase event. It is the join root for all revenue queries. Do not filter on `status = 'complete'` unless you specifically want to exclude in-flight orders from the count. ## Key columns - `order_id` - UUID primary key - `custom

개발 역량이 없어도 외주 개발사의 진행 상황을 명확하게 파악하고 피드백을 줄 수 있다. 필요한 건 기술 지식이 아니라, 올바른 협업 구조다. 이 글은 비개발자 제품 관리자가 바로 적용할 수 있는 투명한 피드백 루프와 점검 방식을 소개한다. 외주 개발에서 비개발자가 소외되는 이유는 무엇인가? 외주 개발사와 일을 시작하면 처음 며칠은 소통이 활발하다. 요구사항 정리, 계약, 착수 미팅까지는 순탄하다. 문제는 그 이후다. 개발이 시작되면 대화의 언어가 바뀐다. "API 연결 중", "백엔드 스키마 설계 단계", "프론트 컴포넌트 분리 작업"처럼 전공자가 아니면 체감하기 어려운 표현들이 보고서를 채운다. 이 상태에서 비개발자가 할 수 있는 질문은 사실상 하나뿐이다. "잘 되고 있나요?" 그리고 돌아오는 답도 하나다. "네, 잘 되고 있습니다." 이 구조는 어느 개발사가 나쁜 의도를 가져서 생기는 문제가 아니다. 개발자는 기술 언어로 사고하고, 비개발자는 결과와 흐름으로 사고한다. 이 두 언어 사이에 다리가 없을 때 소외가 생긴다. 그리고 이 소외는 감정의 문제가 아니라 실질적인 리스크다. 방향이 틀어진 채 몇 주가 흐르면, 다시 맞추는 비용은 처음보다 훨씬 커진다. 비개발자가 개발 과정을 직접 점검할 수 있는 구조가 필요한 이유가 여기 있다. 비개발자가 진행 상황을 파악할 수 있는 협업 구조란? 투명한 협업 구조는 "보고를 더 자주 받는 것"이 아니다. 받는 정보의 언어와 형식을 바꾸는 것이다. 포텐랩은 매주 진행 상황을 공유하는 주간 피드백 루프를 팀 표준으로 운영한다. 이 루프의 핵심은 세 가지다. 무엇이 완료됐는가 : 이번 주에 실제로 만들어진 것, 확인 가능한 것. 다음 주에 무엇을 만드는가 : 다음 단계에서 기대할 수 있는 결과물. 막힌 것이 있는가 : 결정이 필요하거나 확인이 필요한 사항. 이 세 가지가 매주 비개발자도 읽을 수 있는 언어로 정리된다면, 소통 구조는 이미 절반 이상 해결된 것이다. 기술 용어 없이 "로그인 화면 완성, 다음 주엔 상품 목록 화면 작업"이라고 쓸 수 있다면, 비개발자는 지금 어디쯤 왔는지 감을 잡을 수 있다. 주간 피드백 루프를 실제로 설계하는 방법 주간 루프가 형식적인 보고에 그치지 않으려면 구조가 있어야 한다. 아래는 포텐랩이 프로젝트마다 적용하는 주간 피드백 사이클의 구성이다. 1단계 — 주간 업데이트 문서 공유 매주 정해진 요일에 개발팀이 업데이트 문서를 공유한다. 이 문서에는 완료된 기능, 다음 주 작업 항목, 그리고 결정이 필요한 사항이 포함된다. 형식은 슬랙 메시지든, 노션 페이지든 팀이 합의한 채널이면 된다. 중요한 건 형식보다 주기와 언어다. 매주 같은 날, 비개발자가 읽을 수 있는 언어로. 2단계 — 화면으로 확인 가능한 결과물 공유 텍스트 보고만으로는 실제로 무엇이 만들어졌는지 체감하기 어렵다. 그래서 주간 업데이트에는 화면 캡처, 동영상 클립, 또는 테스트용 링크가 함께 제공된다. "로그인 기능 완료"라는 문장보다 실제 작동하는 화면을 보는 것이 훨씬 구체적인 판단 근거가 된다. 3단계 — 비개발자가 직접 테스트하는 시간 개발팀이 보여주는 것만 보는 게 아니라, 비개발자가 직접 써보는 단계가 필요하다. 이 과정에서 "버튼이 너무 작다", "이 순서가 직관적이지 않다" 같은 피드백이 나온다. 기술 지식이 없어도 할 수 있는 피드백이고, 이런 피드백이 제품의 방향을 바로잡는다. 4단계 — 다음 주 작업 범위 합의 이번 주 결과를 확인한 뒤, 다음 주에 무엇을 만들지 함께 정한다. 이 단계에서 비개발자는 우선순위를 조정할 수 있다. "이 기능보다 저 기능이 먼저 필요하다"는 판단을 매주 할 수 있는 구조다. 우선순위는 비개발자가 가장 잘 아는 영역이다. 비개발자가 개발 진행 상황을 점검하는 실질적인 기준은? 개발 진행 상황을 평가할 때 기술적 판단을 할 필요는 없다. 다음 세 가지 기준으로 충분히 점검할 수 있다. 점검 항목 확인 방법 좋은 신호 주의가 필요한 신호 완료 결과물 화면 또는 테스트 링크로 직접 확인 매주 눈에 보이는 결과물이 있음 텍스트 보고만 있고
