AI Agent 的记忆系统通常只解决一个问题：「记住」。gbrain 存知识图谱，Hindsight 存向量，Memory tool 存偏好。三个仓库堆满数据，但你问 Agent「我上周看的那篇关于 Agent memory 的文章说了什么？」——它答不上来。不是因为记不住，是因为它的记忆系统没有「采集」这一层。 这就是 Knowledge-and-Memory-Management（KMM）的定位：不是另一个记忆数据库，而是一个 知识采集 → 精炼 → 召回 → 同步 的全链路插件。v0.0.2 把这条链路做完了。 架构思路：把「采集」和「记忆」解耦 KMM 不做记忆存储，它只做三件事： 采集 — 从 40+ 工具把原始知识拉进来 精炼 — 把原始材料变成结构化笔记 + 知识图谱节点 同步 — 写 OneDrive，让所有设备共享同一个知识池 下方是三层采集管线示意： 层 工具数 代表工具 网页 9 Scrapling (CF 绕过)、Chrome DevTools Protocol、GStack Browser 视频 12 抖音批量转录、yt-dlp、Whisper ASR (99 语种) 文档 9 SenseNova PDF/PPT/Word 引擎、MinerU、book_cache (710+ 本) 3 层召回：不让任何一条知识掉队 搜索时先查本地 FTS5（毫秒级），没命中就走 Hindsight 向量（语义近似），再不中就落 gbrain 知识图谱（关联推理）。三层兜底，基本不存在「查不到」的情况。 代码片段：rclone 做云盘双向同步 KMM 的 CloudSyncEngine 不造轮子，直接用 rclone 做统一同步层。核心代码很直白： class CloudSyncEngine : def __init__ ( self ): self . _check_rclone () def _check_rclone ( self ): result = subprocess . run ([ " rclone " , " version " ], capture_output = True , text = True ) if result . returncode != 0 : raise RuntimeError ( " rclone not installed " ) def bidirectional_sync ( self , local_path , remote_path ): """ 双向增量同步，每 4h 自动执行 """ cmd = [ " rclone " , " bisync " , local_path , remote_path , " --resync " ] return subprocess . run ( cmd ) 这没什么黑科技，关键是架构决策：用 rclone 支持 12+ 云盘（OneDrive / 阿里云盘 / 百度云盘 / Dropbox / Mega / 天翼云等），不需要为每个云盘写专属 SDK。一份配置，双向同步，cron 每 4 小时自动执行。 一个完整的采集流 用户丢过来一个抖音视频链接 → collect_video() 自动走三条线并行： yt-dlp 下音频 → Whisper ASR 转文字 → PaddleOCR/EasyOCR 提关键帧文字 。输出汇总后 → generate_note() 写结构化笔记 → create_note() 入 gbrain 知识图谱 → sync_to_cloud() 推 OneDrive。全自动，零人工参与。 踩过的坑 不要用 Python 重写云盘同步 。KMM v0.0.1 试过直接调各云盘 REST API，token 刷新、分片上传、断点续传全要自己处理，维护成本极高。v0.0.2 切到 rclone bisync 后问题归零。 视频分析不只看语音 。抖音很多技术号用字幕 + PPT 画面讲内容，语音只占信息量的 60%。必须 OCR 做画面补充，否则丢失大量知识。 去重不做在采集层 。采集层只管拉，去重交给 gbrain 的 content_hash 和 nightly_maintenance 的 orphan compaction，职责分离更干净。 适用场景 如果你的 AI Agent 已经跑了一段时间，积累了几千条笔记 / 几百个知识图谱节点，但你还是觉得「它好像什么都不懂」——问题很可能出在知识摄入链路上。KMM 适合你已经有一套记忆系统，缺的是一个自动化的知识采集和同步层。 仓库： github.com/mage0535/Knowledge-and-Management ，MIT 协议，PR

GitHub added a tiny field to the Copilot usage metrics API this week that is going to create a lot of very confident spreadsheets. Enterprise and organization admins can now see ai_credits_used in the user-level Copilot usage reports. One field. Per user. Available for single-day and 28-day reports. It is not the invoice, and GitHub is careful to say it is a consumption signal rather than a billed total. Still, the shape is obvious. Now AI usage can sit next to adoption, activity, team, department, cost center, and whatever else the company already exports into a dashboard. That is useful. It is also exactly how a tool metric becomes a management metric. And once that happens, the question is no longer "can we measure AI usage?" The question is "what weird behavior will this metric create?" every useful metric becomes a temptation I understand why this field exists. If a company is paying for Copilot, especially with usage-based pieces attached to more expensive models and premium features, it needs some way to understand consumption. Platform teams need budget signals. Engineering leaders need adoption signals. Procurement needs something more concrete than "people seem to like it." Finance will eventually ask why one org burns through credits much faster than another. That is normal. The problem starts when a consumption signal is treated as a productivity signal. High AI credit usage might mean a developer is doing valuable work with agent mode, code review, test generation, refactoring, or research. It might also mean the developer is stuck, repeatedly asking the model to solve the wrong problem, generating code that gets deleted, or using a heavyweight model where a small one would have been fine. Low AI credit usage might mean a developer does not need much help. It might mean the work is mostly design, review, debugging, incident response, mentoring, or architecture. It might mean the codebase is small and well understood. It might mean the developer is skept

Every time you open a new session with an AI coding tool, it starts from zero. It does not know what you decided yesterday, what failed last week, or what comes next. You have to explain the project again. And again. EGC (Extended Global Context) fixes this. EGC is a local runtime that gives every AI coding tool you use a persistent memory. At the end of each session, the AI saves what it learned: decisions made, what failed, your preferences, what comes next. At the start of the next session, it loads that state back automatically. One install. Every tool. Every session. Website: https://fmarzochi.github.io/EGCSite What it looks like in practice You open Claude Code on a project you have not touched in two weeks. Without typing anything: State loaded from egc-memory via ~/.egc/state/Projects--MyApp.md Context and preferences acknowledged. Ready to pick up: - Test full install on a clean machine - Add GEMINI.md with session memory protocol - Publish v1.0.1 fix after clean install test passes The AI already knows what you were building, what decisions you made, what failed, and exactly where you stopped. You did not type anything. You just started working. How it works EGC ships two MCP servers that run locally during every session. egc-memory: 14 tools for persistent memory Tool What it does get_state Loads project memory at session start update_state Saves decisions, preferences, and next steps store_decision Persists a single decision to SQLite query_history Returns past decisions by timestamp search_history Full-text search with BM25 ranking working_memory_set Stores transient context with a TTL lesson_save Records cross-session knowledge with confidence decay lesson_recall Retrieves active lessons above a threshold detect_patterns Surfaces repeated commands and recurring errors compress_observations Compresses hook events to save token budget State files live at ~/.egc/state/<project-slug>.md . One file per project. Plain Markdown. Human-readable. egc-guardian:

There is a class of feature that used to be impossible to ship for free: anything that needed a language model. You wired up an API key, you ate the per-token bill, and every prompt your users typed went off to someone else's server. For a small public tool, that math usually killed the idea before it started. That changed. Recent versions of Chrome ship a language model, Gemini Nano, and expose it to any web page through the Prompt API . The model runs on the user's own machine. No API key. No inference bill. No data leaving the browser. We put this into a real, live tool, a free Mermaid diagram editor where you describe a diagram in plain English and the browser writes the Mermaid code for you. This post is the developer's version of that story: how the API actually works, the code that makes a small on-device model trustworthy, and an honest accounting of what you gain and what you give up. What "AI in the browser" means in 2026 The important word is built-in . This is not WebGPU plus a 4 GB model you download and run yourself. The model ships with Chrome, and you talk to it through a small standard-track JavaScript API. As of Chrome 148, the Prompt API is stable for web pages (it had been available to extensions since Chrome 138). It is the general-purpose member of a growing family of built-in APIs: Prompt API ( LanguageModel ): general natural-language prompting, now multimodal (text, plus image and audio input). Summarizer, Writer, Rewriter, Proofreader : task-specific, text-to-text. Translator and Language Detector : backed by expert models, desktop only. The Prompt API is the one you reach for when you need something the task APIs don't cover, like "turn this description into Mermaid source." So that is the one this post focuses on. The 15-line version Here is the whole happy path. Check availability, create a session, prompt it. // Feature-detect first. Old browsers won't have this at all. if ( ' LanguageModel ' in self ) { const status = await LanguageMod

I run a homelab with four RTX 3090s — 96 GB of VRAM, 44 CPU cores. For two weeks I tried to make it my daily driver for local LLM inference instead of paying for cloud APIs. I got it working. Then I looked at the numbers and subscribed to a paid API anyway. Here's the uncomfortable part, and the optimizations that still made it worth doing. ## The setup 4× RTX 3090 (Ampere — no native BF16), 96 GB VRAM total, 44 cores Models: Qwen3.6-35B-A3B (Q8_0, MoE) and Qwen3-Coder-Next (Q6_K, hybrid) llama.cpp in router mode + OpenWebUI Ceiling I hit: ~105 tokens/second ## The 6% problem The wall wasn't compute. GPU utilization sat at 6%. The bottleneck was CPU orchestration — llama.cpp dispatches across multiple GPUs sequentially, so the cards spent 94% of the time idle waiting on each other. Throwing more VRAM at it does nothing for this. ## What actually moved the needle | Change | Effect | |---|---| | --ubatch-size 512 | +40% throughput | | KV cache quantization (Q4_0) | 4× VRAM savings | | Speculative decoding (n-gram) | 2.5× speedup on repetitive tasks | | YaRN rope scaling | context extended to 1M tokens | Two things surprised me: MoE models tolerate aggressive quantization far better than dense ones — inactive experts don't eat bandwidth, so the quant hit lands softer. The 3B active -parameter model was great at local decisions but fell apart on coherence past ~300–400 lines of code — fine for a function, not for cross-file consistency. ## The conclusion I didn't want At ~11 kWh/day, plus hardware depreciation, against current API pricing, the math doesn't favor local for interactive work. The single biggest improvement to my daily AI workflow was paying for an API. Local still wins for privacy, high-volume batch jobs, or uncensored experimentation — but not as a general cloud replacement. It's an economics problem, not a capability one. I wrote up the full cost breakdown and the exact llama.cpp router configs on aipster.com . If you're weighing a local rig, I also benc

For 13 years I have worked in production at a steel-tube manufacturer. Not in an office — on the floor, with the machines, the night shifts, the handovers at 6 a.m. A few years ago I started building software in my free time. Not tutorials for their own sake — tools that solve problems I actually see every day. Why a factory worker writes code In production you learn one thing fast: it does not matter what looks good on a slide. It matters what works at shift handover. That perspective turned out to be my biggest advantage as a self-taught developer — I know the problem before I write the first line. What I have built PIPEZ — a shift & part-count PWA. Offline-capable, running on Cloudflare Workers + D1, live in production to capture shift and piece-count data that used to live on paper. A tool-management app. A multi-user client-server app with optimistic concurrency and a local AI assistant, used daily in the office to manage the lifecycle of dies in tube production. DeepCode — an agentic AI coding client. Electron + React + TypeScript, with its own tool loop, a swarm mode, and CI/tests. The project I am proudest of. Plus multi-agent systems, RAG pipelines, and n8n automations that run every day. The stack Python/FastAPI, TypeScript/React, Node, Docker, PostgreSQL + pgvector, Cloudflare Workers, MCP, computer vision. Writing in public I will be writing here about the bridge I keep coming back to: real production experience plus building with AI. If you are automating something messy and real, I would love to compare notes.

Day 9. Template matching works. But screen sizes, resolutions, and Android versions might break everything. Eight days ago, the agent was an idea. Now it can read text, handle interruptions, and find icons on a screen. But there's a question I've been avoiding: does it work on any phone other than mine? The Cross-Device Problem Every screenshot I've taken, every icon I've cropped, every coordinate I've mapped—it's all on one device. My phone. Same screen size. Same resolution. Same Android version. Same DPI. Template matching relies on reference images that look exactly like the target on screen. Change the screen density, change the icon size, change the font scaling, and the match confidence drops. Suddenly "send_button.png" doesn't match anymore, and the agent can't press send. This isn't a bug in my code. It's a fundamental challenge in computer vision: reference-based matching breaks when the visual context changes. Today's Experiment I tested the same agent on a friend's phone—different manufacturer, different Android version, slightly larger screen. The results were humbling. Task My Phone Friend's Phone OCR (text recognition) ✅ 95% accuracy ✅ ~90% accuracy Find "Mom" in contacts ✅ Found ✅ Found Template match: send button ✅ 94% confidence ❌ 62% confidence Template match: back button ✅ 91% confidence ❌ 58% confidence OCR held up reasonably well because text is text. Fonts might change slightly, but the characters are the same. But the icons—the send button, the back arrow—were rendered at a different size and slightly different pixel arrangement on my friend's device. The agent failed to send the message. Why This Matters An AI agent that only works on one phone isn't an agent. It's a script. If I want this to be useful to anyone else—or even to myself if I change phones—it needs to be device-agnostic. Possible Solutions I'm Exploring Solution Pros Cons Multi-resolution icon library Simple. Just crop icons at different DPIs. Tedious. How many variants are eno

Securing LLM Agent Teams: Inside NRT-Defense v0.4.0 Multi-turn autonomous LLM agents are expanding rapidly in safety-critical systems. However, a major vulnerability has been exposed by Lee et al. (2026) in the NRT-Bench paper : adaptive multi-turn attacks can exploit disjoint model vulnerabilities, causing a 8.7% to 12.1% loss of Critical Safety Functions (CSFs) . To solve this, I am open-sourcing NRT-Defense , an adaptive multi-turn defense framework designed to monitor agent sessions and reduce the attack success rate to <1% . The Threat: Context Drift and Disjoint Exploits Standard guardrails evaluate prompts in isolation (single-turn). Attackers leverage this by spreading an exploit across multiple conversational turns. Turn by turn, the context drifts until the agent team completely bypasses its safety containment. The NRT-Bench paper demonstrated this in a simulated nuclear power plant control room with 5 operator roles, 4 attack channels, and 6 critical safety functions. The results were alarming: Metric Value Attack success rate 8.7% — 12.1% Sessions analyzed 149 Models tested 4 frontier LLMs Vulnerability overlap Nearly disjoint The key finding: vulnerabilities are nearly disjoint across models . An attack that works against GPT-4 may not work against Claude. This means model diversity is itself a defense — but only if you can detect and respond to attacks in real-time. The Solution: 3-Step CMPE Defense nrt-defense neutralizes this threat through a continuous, multi-component pipeline: Per-Turn Message Analysis: Evaluates channel risk and turn-escalation metrics. Each message is scored for adversarial content using keyword detection, pattern matching, and channel-specific risk weights. Real-Time CSF Monitoring: Tracks 6 operational critical safety functions simultaneously. Risk accumulates over turns and triggers alerts when thresholds are breached. Context-Aware Misdirection Prompt Engineering (CMPE): When an anomaly is detected, instead of a blunt reject

Atlantic reporter Alex Reisner recently uncovered four datasets of music being used to train AI models and made them fully searchable for the public.

If you’ve spent any time working with autonomous AI coding agents recently, you know the drill. You give the agent a straightforward task: "Add a user profile page and link it to the navbar." The agent says, "I've got this." It writes some code. You run it, and it throws an import error. You paste the error back. The agent apologizes, rewrites the file, and now your routing is broken. You paste that error back. Ten iterations later, your config is mysteriously deleted, the navbar is entirely missing, and the agent is trying to install a deprecated version of React. This is the AI Agent Doom Loop. It happens because current agent frameworks mistake intelligence for discipline. We dump a 10,000-token SYSTEM_PROMPT.txt telling the agent everything about our project, hoping it remembers the architecture constraints on step 45 of its execution loop. It rarely does. I built Agent Rigor because I got tired of babysitting agents that code themselves into corners. The Root Cause: Context Rot When an agent starts a task, its context is pristine. But as it reads files, executes commands, and hits errors, its context window fills up with junk stack traces and previous failed attempts. By the time it's 20 steps deep, the original system prompt you carefully crafted is buried. The agent forgets the architecture guidelines. It starts prioritizing the immediate error in front of it over the overall goal. This is when it starts guessing, hallucinating, and making things worse. The Solution: Progressive Disclosure and Empirical Discipline Agent Rigor isn't a new LLM or a magic prompt wrapper. It's an operating system for agents that enforces strict empirical discipline . Instead of one massive prompt, Agent Rigor uses a 3-tier hierarchy: L1 (Apex Kernel): The absolute, non-negotiable laws. (e.g., "Never guess an API signature. Always grep or read the file first.") L2 (Phase Directors): Orchestration that only loads when the agent enters a specific phase (Planning, Execution, Verifica

Most carbon footprint apps do the same thing: Quiz → "Your footprint is 120 kg CO₂/week" → Generic tips → User never returns. That's not a coaching experience. That's a guilt trip with no follow-through. For PromptWars Virtual — Challenge 3 (Carbon Footprint Awareness & Reduction), I built CarbonCompass with a different premise: Not just measure. Guide. Live demo: https://prompt-wars-virtual-hackathon-8u1kxxwh1-mithunvisveshs-projects.vercel.app/ The Problem with Existing Carbon Tools I started by looking at what already exists — Capture, Klima, JouleBug. Each of them calculates a footprint accurately. But they all fail at the same step: the recommendation layer. "Install solar panels." "Buy an EV." "Go vegan." These are structurally correct but useless for a hostel student in Chennai who travels by bus and eats at the mess. They're recommendations designed for a demographic that already has money and flexibility. CarbonCompass is built around two real Indian users: Aditi — a college student in Chennai. Bus commute, hostel mess food, shared room electricity. Her biggest carbon lever is food waste, not transport. Rohan — a tech professional in Bengaluru. Petrol car + scooter commute, air-conditioned 2BHK, frequent food delivery. His biggest lever is home energy, not diet. The same app, two users with different lifestyles receive coaching tailored to their highest-impact opportunities. That's the core product promise. The Architectural Decision That Made Everything Work Before writing a single line of code, I ran this prompt in Google Antigravity's Plan Mode: You are a senior product architect. Before coding: Generate user personas Design a SINGLE shared calculation module that the Dashboard, Impact Simulator, and AI Coach all call with the same inputs Create the data schema Propose page architecture Flag risks for a one-week build Do not write code yet. Create an Implementation Plan. The agent produced a full Implementation Plan artifact — a structured document I cou

This is a submission for the June Solstice Game Jam TypeForge: Turing-Inspired Intelligent Typing Coach What I Built TypeForge is a premium typing coach aligned with Apple's Human Interface Guidelines, built to help typists build speed and accuracy through automated, localized error diagnostics. TypeForge analyzes keystroke performance to isolate specific character transitions that cause delay or accuracy drops, then generates custom, adaptive exercises targeting those weaknesses. Developed for the June Solstice Game Jam, the project celebrates the power of computing and accessibility by turning raw diagnostics into a personalized educational experience. The solstice theme represents the journey of transition: taking a typist from darkness, meaning slow, error-prone typing, into light, meaning fluid, expert flow.

How I Built a Real-Time Bounty Marketplace with Supabase and 14-Layer Edge Security I wanted to build a platform where anyone can post a task (a "bounty"), set a reward, and have people complete it with verifiable proof. Think freelance work, but optimized for quick, composable task completion — with proof submission as the core trust mechanism. The result is BountyClaimer — a real-time marketplace running on Supabase + Vercel with a security system baked into Edge middleware and scattered across every layer of the stack. 🛠️ The Tech Stack Frontend: React + Vite + TypeScript Backend: Supabase (PostgreSQL, Realtime, Storage, Auth) Payments: Stripe Hosting: Vercel (Edge Middleware) Security: Custom "Armadillo" system (14 layers) Architecture Pattern: Phoenix Architecture for real-time state consistency 🔄 The Core Workflow Post — A user posts a bounty with a reward and description Claim — Others browse and claim available bounties Submit — The claimer completes the work and submits proof (images, video, audio, text, files) Settle — The bounty owner reviews and approves — funds are released Sync — Real-time updates keep both sides in sync instantly The hardest parts were real-time state sync across multiple users , anti-abuse without hurting legitimate users , and security at the edge . 🏛️ The Phoenix Architecture One pattern I'm particularly proud of is what I call the Phoenix Architecture — a real-time state management approach that ensures every client sees the same truth without polling. The core idea: instead of each client fetching data and hoping it's current, database changes (bounty status updates, proof submissions, claim state transitions) are broadcast out via Supabase Realtime. Every connected client receives the same event stream and updates locally. // The Phoenix pattern — subscribe to changes once, // update locally from the event stream const channel = supabase . channel ( `entity- ${ id } ` ) . on ( ' postgres_changes ' , { event : ' * ' , schema : '
