We live in an era where scientific breakthroughs are published faster than we can read them. For the biohacking community, the gap between a new PubMed study on NAD+ precursors and actually knowing what dose to take is a chasm of manual research. What if you could build an LLM Agent that monitors research papers, processes them through a RAG (Retrieval-Augmented Generation) pipeline, and maps findings to your specific health profile? In this tutorial, we are building Paper-to-Action , a state-of-the-art agentic workflow using LangGraph , ChromaDB , and Mistral-7B . This isn't just a simple bot; it's a multi-stage reasoning engine designed to turn raw academic data into actionable health interventions. If you've been looking to master AI agents and personalized medicine automation, you’re in the right place. 🚀 The Architecture: From Raw Paper to Personalized Habit Traditional RAG pipelines are linear. To handle the nuance of medical research, we need a "looping" logic. We use LangGraph to manage the state of our agent, allowing it to decide if a paper is relevant before attempting to extract a protocol. System Flow graph TD A[Start: Keyword Trigger] --> B[Search PubMed/Arxiv API] B --> C{Relevance Filter} C -- No --> B C -- Yes --> D[Store in ChromaDB] D --> E[RAG: Extract Intervention Protocol] E --> F[Cross-Reference with User Profile] F --> G[Generate Personalized Action Plan] G --> H[End: Push to Health Checklist] Prerequisites To follow this advanced guide, you'll need: LangGraph : For the agentic state machine. ChromaDB : As our high-performance vector store. Mistral-7B : Running via Ollama or vLLM for local, private inference. Python 3.10+ Step 1: Defining the Agent State In LangGraph, everything revolves around the State .

Qisquiz: A Qiskit v2.X Certification Prep App I built Qisquiz , a web app for learning Qiskit v2.X and preparing for the IBM Certified Quantum Computation using Qiskit v2.X Developer - Associate certification exam. You can try the app here: https://qisquiz.vercel.app/ The GitHub repository is here: https://github.com/dorakingx/qisquiz The concept of Qisquiz is simple: Master Qiskit, one quiz at a time. In other words, Qisquiz is a quiz-based certification prep app that helps learners study Qiskit one question at a time. The target exam is: Exam C1000-179: Fundamentals of Quantum Computing Using Qiskit v2.X Developer Why I Built Qisquiz Qiskit is one of the most important development tools for learning and building quantum computing applications. It is useful for creating quantum circuits, running simulations, using IBM Quantum hardware, and experimenting with quantum algorithms. However, Qiskit v2.X includes several APIs and concepts that learners need to understand carefully. For example, certification prep requires knowledge of topics such as: Qiskit Runtime SamplerV2 EstimatorV2 PUBs, or Primitive Unified Blocs BackendV2 backend.target Transpilation ISA circuits Dynamic circuits OpenQASM 3 Result object handling Little-endian and big-endian interpretation These topics can be learned by reading documentation, but I felt that active practice through quizzes is especially useful for exam preparation. That is why I built Qisquiz , a quiz-based learning app focused on Qiskit v2.X. What Is Qisquiz? Qisquiz is an independent quiz-based learning app for Qiskit v2.X. The current version is organized around the 8 sections of the IBM Qiskit v2.X Developer certification exam. The current question bank includes: 120 original questions 44 code-based questions 40 hard questions 8 sections 15 questions per section Qisquiz is not an official IBM or Qiskit product. It is an independent learning tool that I built to help myself and other learners prepare more effectively. Covered E

İlk yazıda Event Driven Architecture’ın temel kavramlarını, Kafka üzerinde topic/channel tasarımını, event-command ayrımını, schema contract’ları ve producer-consumer ilişkisini ele aldık. Bu yazıda odağı bir adım ileri taşıyıp event’in platform içindeki yaşam döngüsüne bakacağız. Çünkü EDA tasarımında asıl zorluk yalnızca event üretmek değildir. Asıl mesele, üretilen event’in güvenilir, izlenebilir, tekrar işlenebilir, zenginleştirilebilir ve farklı tüketiciler tarafından kullanılabilir hale gelmesidir. Bu yazıda şu sorulara odaklanacağız: Ham event platforma geldiğinde ne olur? Event nasıl doğrulanır, zenginleştirilir ve tüketilebilir hale gelir? Raw, validated, enriched ve curated topic’ler nasıl konumlandırılmalıdır? Bu yapı modern lakehouse mimarilerindeki Medallion yaklaşımıyla nasıl ilişkilendirilebilir? DLQ ve alert topic’leri ne zaman devreye girer? Replay, idempotency, monitoring, security ve governance nasıl düşünülmelidir? Event Pipeline Nedir? EDA mimarilerinde özellikle data platform projelerinde event’ler genellikle bir yaşam döngüsünden geçer. Bu yaşam döngüsü şöyle modellenebilir: raw -> validated -> enriched -> curated | | v v dlq alert Bu yapı, veri akışının aşama aşama olgunlaşmasını sağlar. Raw topic kaynaktan gelen ham event’i taşır. Validated topic schema ve temel kalite kontrollerinden geçmiş event’leri içerir. Enriched topic event’in referans veriler veya başka veri kaynaklarıyla zenginleştirilmiş halidir. Curated topic ise tüketiciler için güvenilir, normalize edilmiş ve iş anlamı netleşmiş event’leri temsil eder. Event Pipeline ve Medallion Architecture İlişkisi Bu yapı, modern lakehouse mimarilerinde sık kullanılan Medallion yaklaşımıyla doğal bir benzerlik taşır. Lakehouse tarafında Bronze katmanı ham veriyi, Silver katmanı temizlenmiş ve zenginleştirilmiş veriyi, Gold katmanı ise iş tüketimine hazır veri ürünlerini temsil eder. Kafka üzerindeki raw, validated, enriched ve curated topic’leri de benzer bir olgunlaşma mantığını akan veri ü

Anthropic published a thoughtful guide to making skills. It is worth reading, but it's a map of work you should not have to do. The Claude Code team wrote a piece on how they use agent skills . If you make skills, read it. It is honest and tells you something important: making a good skill is real work. Here's what the guide covers. It sorts skills into nine categories. It explains progressive disclosure, where the agent knows which files to load and when. It covers scripts, config files, combining skills together, and writing the description so the model reaches for the skill at the right moment. All of that is true and useful. It is also a lot to learn. And most of it exists only because you are doing the work by hand. We're SkillsCake . We make and score agent skills all day. So we read this guide a little differently than someone meeting skills for the first time. Here's what we think. Skills are infinite The guide splits skills into types: library reference, verification, and so on. That is a helpful way to teach a class. It is not what a skill actually is. A skill is prose that tells an agent how to do one thing, sometimes with scripts attached. The set of possible skills is not nine boxes. It is every job you could describe in writing; it's infinite. Categories are how a person gets a handle on something that open-ended. They are scaffolding for learning, not the shape of the thing. This matters because the moment you think in categories, you start bending your skill to look like the example in its bucket. Your real job rarely fits the bucket. The best engineered skill is the one written for your exact task, by an expert. Doing it yourself might not be worth it Progressive disclosure, scripts, config, descriptions tuned for the model, gotchas earned by failing, and eval loops: none of that is busywork. It's how a good skill gets built by hand. The guide is not overcomplicating anything. It is being honest about what the manual path costs. But that is the poin

Hackers are convincing Meta’s AI support chatbot to let them take over other peoples’ accounts: A video posted on X showed the step-by-step process to hack someone’s Instagram account. The hacker allegedly used a VPN to spoof the targets’ presumed location to avoid triggering Instagram’s automated account protections. Then, the hacker opened a chat with Meta AI Support Assistant and asked the bot to add a new email address to the target’s account. The chatbot can be seen sending a verification code to the email address provided by the hacker; the hacker then shares the verification code with the chatbot, which prompts the chatbot to show a button to “Reset Password.” The hacker enters a new password and takes over the victim’s account...

Microsoft launched seven new in-house AI models at Build 2026 on June 2, 2026, marking the company's most significant push yet to build its own frontier AI stack independent of OpenAI. The centerpiece is MAI-Thinking-1, Microsoft's first large-scale reasoning model, built from scratch on clean commercially licensed data using a sparse Mixture of Experts architecture. Alongside it: MAI-Code-1-Flash, a 5-billion-parameter coding model that outperforms Claude Haiku 4.5 by 16 percentage points on SWE-Bench Pro while using 60% fewer tokens on complex tasks. This is the complete developer guide to all seven MAI models, their specs, benchmarks, deployment paths, and what they mean for the AI development ecosystem. Why Seven Models at Once? The strategic context matters. For three years, Microsoft's AI product surface — GitHub Copilot, Azure AI, Bing Chat, Microsoft 365 Copilot — ran almost entirely on OpenAI models. The Build 2026 announcement is Microsoft's public declaration that it is building a parallel, proprietary model stack. Every new MAI model is trained from scratch using "clean and appropriately licensed data, without distillation from third-party models" — language that directly addresses the intellectual property concerns that have accompanied third-party model licensing. The distribution strategy is equally deliberate. Microsoft is not routing MAI models exclusively through Azure. MAI-Thinking-1 and MAI-Code-1-Flash are available via Fireworks AI, Baseten, and OpenRouter — three infrastructure providers that collectively reach developers who explicitly do not want cloud vendor lock-in. This signals a platform-first posture: Microsoft wants MAI to become a model ecosystem, not just an Azure feature. MAI-Thinking-1: The Reasoning Flagship MAI-Thinking-1 is Microsoft's answer to Claude Opus 4.x and GPT-5.5 on the reasoning side of the model spectrum. The architecture is a 35-billion-parameter active / approximately 1-trillion-parameter total sparse Mixture of Ex

Keeping up with trending technical topics and new tools on developer forums can be time-consuming. To save time, I wanted to automate the process of finding popular articles, reading the comments to understand community sentiment, and drafting a summary. While I could write a standard Python script to scrape the dev.to API, simple scripts tend to be brittle. If an article doesn't have comments yet, a basic script will likely crash unless you write extensive error-handling logic. Instead of a rigid script, I built an Agent —a program that can dynamically reason about errors and adjust its approach. If one task fails, it can figure out the next best step. In this tutorial, I'll show you how to build a Trend-Spotting Agent using Python, the Google Agent Development Kit (ADK) , and Gemini 2.5 Flash. What We're Building We are going to write a Python application that acts as an autonomous agent. We'll give it three abilities: Search the dev.to API for rising technical articles based on specific tags. Dynamically fetch the top comments of those articles to read real community sentiment. Automatically draft a newsletter-style article on your DEV.to account summarizing its findings. Prerequisites Python 3.9+ installed on your machine. Google ADK . (Check out the Google ADK Docs if you need help installing). A DEV API Key . Grab this from your DEV.to account settings under "Extensions" and throw it in a .env file. Step 1: Giving the Agent its "Hands" (API Tools) Large Language Models (LLMs) are incredibly smart, but out of the box, they can't actually do anything on your computer. The coolest part about Google ADK is that we can write standard Python functions, hand them to the LLM as "tools", and let the AI decide how and when to use them. Let's write our API functions. Tool 1: Finding Rising Articles Here is our function to fetch rising articles. Pay close attention to the docstring ( """Fetches the top...""" ). We aren't writing this for other developers; the ADK actually

Most people use these technologies every day. Almost nobody knows they exist. Every time you open YouTube, browse Instagram, join a Zoom meeting, or play an online game, your router is quietly performing a series of networking tricks behind the scenes. Those tricks have names: NAT SNAT DNAT PAT Port Forwarding They sound intimidating. They're actually much simpler than they appear. Let's break them down using something familiar: your home Wi-Fi. The Problem the Internet Had to Solve Imagine a family of five living in one house. Everyone owns a device: Laptop Phone Smart TV Gaming Console Tablet Each device needs internet access. The problem? Your Internet Service Provider usually gives you only one public IP address . Something has to manage all those devices sharing a single internet connection. That's where NAT comes in. NAT: The Receptionist of Your Network NAT stands for Network Address Translation . Think of NAT as a receptionist in an office building. People inside the building have room numbers: Laptop = Room 101 Phone = Room 102 TV = Room 103 But when communicating with the outside world, everyone uses the building's main address. The receptionist keeps track of who sent what. Your router does exactly the same thing. What Happens When You Visit Google? Inside your home: Laptop 192.168.1.10 Your router: Public IP 49.x.x.x When you open Google: 192.168.1.10 ↓ Router ↓ 49.x.x.x ↓ Google Google never sees your private IP. It only sees your router's public IP. That's NAT in action. SNAT: Changing the Sender's Address SNAT stands for Source Network Address Translation . The keyword is: Source It changes the sender's address. Before leaving your network: Source: 192.168.1.10 After SNAT: Source: 49.x.x.x The router replaces your private IP with its public IP. Without SNAT, websites wouldn't know how to send responses back to you. Real-Life Example Imagine mailing a letter. Instead of writing your bedroom number as the return address, you write the house address. Tha

One of the biggest myths in the software industry is that great engineering teams are built by hiring great engineers. They aren't. I've worked with incredibly talented developers who eventually became disengaged, indifferent, and unwilling to contribute beyond the bare minimum. I've also worked with average developers who grew into exceptional engineers because they were surrounded by a culture that rewarded curiosity, ownership, and continuous improvement. The difference was never talent. The difference was culture. The Toxicity Nobody Talks About When people hear the term toxic workplace , they usually imagine shouting managers, impossible deadlines, public humiliation, and constant pressure. Those environments certainly exist. But some of the most damaging engineering cultures are far more subtle. On the surface, everything appears professional. Meetings are calm. Nobody raises their voice. Everyone speaks politely. The company presents itself as collaborative and mature. Yet beneath that polished exterior exists a culture that quietly destroys accountability and discourages anyone from caring too much. A Simple Pull Request That Revealed a Bigger Problem Recently, while reviewing a pull request, I asked a few straightforward questions: Why are we passing an empty string to a component that doesn't function without an ID? Why is a skeleton component living in a file where it doesn't logically belong? Could this conditional statement be simplified for readability? These weren't major architectural concerns. They weren't requests to redesign the application. They were ordinary engineering discussions—the kind that happen every day inside healthy teams. When Ownership Disappears What happened next was far more interesting than the code itself. Instead of discussing whether the observations were valid, the conversation immediately shifted toward ownership. Who originally wrote the code? Who moved the code? Who was responsible for introducing it? The discussion was n

1. Why I use Kiro I've been using Kiro for almost 1 year now, I'm using it as a Cloud Architect and also to build side projects for fun. The main reason I use Kiro over other tools is how it works with you as an engineer. Over the months, I've noticed certain patterns in how I use Kiro. Let's go over them: Index 1. Why I use Kiro 2. Pair Programming with Kiro 3. Repeatable workflows as Skills 4. Using Plan, Specs and Agents 5. Council of agents 6. Documentation, Documentation, Documentation Final thoughts 2. Pair Programming with Kiro The most common way that I use Kiro is in Pair Programming. Pair Programming is when there are 2 developers working together on the same task, they can work in tandem or one of them can be the one guiding/planning while the other one does the code. In my case, with Kiro, I'm the one doing the guiding and planning while Kiro is the one executing and implementing the code. I'm also using Kiro as my rubber duck. If I have a new idea or I'm working on a blocking bug, I talk to Kiro so it can give me a different point of view, investigate and steer me into good practices. The main reason for me to do it this way is because once the session is over, I can run a prompt/skill to record everything from the session: Kiro, summarize this session and save it into a .memory folder with the format yyyymmdd and as a markdown So then everything that we've done is going to be recorded there. Do you remember everything that you've done yesterday? Maybe. But what about last week? And what about one month ago? I definitely don't remember it. In the classic Software Development Life Cycle, we have tickets, and we have a way that we can recall all this information, but the more detailed context of why you did it is going to be completely missed. Now, with tools like Kiro, this is possible to remember. You just have a .memory folder where you summarize all your sessions. So in the future, we could have a situation like this: Oh, I don't remember what changes

I’ve spent a lot of time lately thinking about why some LLM agents feel "intelligent" while others just feel like chatbots with a slightly better prompt. It almost always comes down to how the system handles memory. When we treat the context window as the only place for state, we hit a ceiling very quickly. To build an actual agent, we have to move away from "one big prompt" and toward a layered memory architecture. Agentic Memory can be categorized in 4 layers by their function: Working Memory: The current context window. It's our RAM—fast, essential, but wiped clean after every session. Semantic Memory: The Vector DB or knowledge base. This is where the "world rules" and global conventions live. It’s the reference manual the agent checks to stay aligned. Procedural Memory: The "how-to" layer. Instead of stuffing every tool description into the prompt, the agent maintains a lean index of skills and pulls in the full implementation only when a specific task triggers it. This keeps the context window clean. Episodic Memory: This is the hardest part. It's the ability to distill a past interaction into a reusable insight. The real engineering challenge here isn't storage—it's the "forgetting" logic. Deciding what is noise and what is a core pattern is where most frameworks still struggle. Depending on the use case, the architecture changes: Reflex Agents: Just Working Memory. Support Agents: Working + Procedural. Coding Agents: The full stack. The gap between a demo and a production-ready agent is usually the distance between simple RAG and a functioning episodic memory. The ability to compress experience into a usable state is still a significant hurdle. Which of these layers are you currently implementing, and how are you handling the "forgetting" logic in your episodic memory?

The Question Nobody Wants to Ask: Does Your Skill Actually Help? You spent an afternoon crafting a carefully structured Skill for your agent. Clear steps, thorough edge-case notes, well-formatted output requirements. You tested it manually a few times, the outputs looked great. You shipped it. Three weeks later, you notice that some task success rates have gone down compared to before the Skill existed. This is not a hypothetical. In May 2026, Microsoft Research published two concurrent papers — SkillLens ("From Raw Experience to Skill Consumption") and SkillOpt ("Executive Strategy for Self-Evolving Agent Skills") — that measured this failure mode at scale. Their finding: negative transfer happens in 25% of cases , and you cannot reliably identify the bad skills just by reading the text. One paper answers "why skills sometimes backfire." The other answers "how to make skills systematically better." Together they sketch a new paradigm for agent capability improvement. Part One: SkillLens — Mapping the Full Skill Lifecycle A Skill Is Not a Point — It's a Pipeline Most practitioners think of a Skill as "a block of text instructions for an agent." SkillLens decomposes this into a three-stage lifecycle : Stage 1: Experience Generation Target model M runs training tasks, producing an experience pool of trajectories (both successes and failures) ↓ Stage 2: Skill Extraction Extractor model E distills the experience pool into a structured skill document — procedural knowledge under a fixed budget ↓ Stage 3: Skill Consumption The same target model M, equipped with the extracted skill, is evaluated on held-out test tasks Notice there are two distinct roles in this chain: the Extractor (distills knowledge from trajectories) and the Target (consumes knowledge to improve task performance). SkillLens's central insight is that these two roles are independent — a strong task executor is not necessarily a strong extractor, and vice versa . Two New Metrics: EE and TE To separate thes

为什么使用代理总弹出“安全验证”？深度解析 Cloudflare 拦截机制与避坑指南 在互联网开发、跨国办公或日常浏览中，使用代理（如 VPN、机场、Socks5、OpenVPN/WireGuard 协议等）已经是不可或缺的技能。 然而，许多人在开启代理后，访问国外网站（如 Dev.to、GitHub、Medium 等）时，频繁遭遇如下提示： Performing security verification This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot. 甚至更让人崩溃的是，有时候点击了验证码，它依然不断刷新，陷入 无限验证死循环 。这并不是你的系统或浏览器损坏了，而是代理网络的特性触发了现代 Web 安全防御机制。本文将从技术原理深入拆解这一现象，并提供切实可行的优化方案。 一、 核心原理：网站安全服务是如何盯上你的？ 现代网站大多会部署 Cloudflare（如 Turnstile 验证） 、Akamai、Imperva 等网络安全与防 DDoS 攻击服务。这些服务通过以下几个维度来评估访问者是“真实人类”还是“恶意机器人（Bot）”： 1. IP 信誉度（IP Reputation）与“连坐”机制 这是最核心的技术原因。代理服务商（特别是商业 VPN 或公共机场）所使用的 IP 地址，绝大多数属于 数据中心（Data Center）机房 IP ，而非普通家庭的 住宅（Residential）IP 。 高密度共用： 同一个代理 IP 节点上，可能同时有成百上千个用户在发起请求。 黑名单牵连： 如果该 IP 下的其他匿名用户正在使用自动化脚本抓取数据、进行端口扫描，或者发起恶意网络攻击，安全系统的风控引擎（如 Cloudflare IP Threat Score）就会瞬间拉高该 IP 的风险等级。当你恰好切换到这个“脏 IP”时，就会被系统无差别“连坐”，要求强制验证。 2. 被动指纹识别（Passive Fingerprinting）与几何特征 安全防御系统不仅看你的 IP 归属地，还会通过深层网络和浏览器几何特征来判断你的真实身份： TLS/SSL 握手特征（JA3 指纹）： 当你通过一些特定协议或混淆模式（如带有特定加密的 TCP 隧道）连接网站时，浏览器发出的 TLS 握手特征可能会发生形变。 TCP/IP 栈特征： 经过代理服务器的转发，数据包的 TTL（生存时间）、Window Size（TCP 窗口大小）等底层参数可能会与你浏览器宣称的操作系统（如 Windows 11 或 Ubuntu 24.04）的标准特征不匹配。 浏览器画布与几何指纹（Canvas/Geometry）： 浏览器的窗口大小、屏幕分辨率以及它们的比例，也是风控系统评估的重要指标。 自动化爬虫脚本（如 Selenium、Puppeteer）在启动时，常常使用死板的默认分辨率（如完美的 1024x768 或 800x600 ）。如果你的代理 IP 本身信誉度低，窗口又处于这些“机器人专属分辨率”下，或者网页窗口大小与物理显示器分辨率比例极其诡异（例如伪造环境时穿帮），就会直接触发拦截。 3. 环境与地缘标签冲突（以 Yandex 浏览器为例） 风控系统对你使用的浏览器品牌同样有一套风险权重评估。 如果你使用的是 Yandex 浏览器 或某些小众、经过重度隐私魔改的浏览器，在配合代理时会变得 极其难通过验证 。Yandex 浏览器虽然基于 Chromium 内核，但其内部由俄罗斯团队集成了大量独特的隐私保护技术与 Canvas 渲染机制，计算出的浏览器指纹非常非主流。 更致命的是 地缘标签冲突 ：欧美的主流网络安全公司（如 Cloudflare）对特定区域标签的客户端流量天然设置了更低的信任阈值。当你 用着 Yandex 浏览器 ，IP 却 挂着美国或日本的代理 时，这种“指纹与地理位置的剧烈冲突”在风控模型眼里极度反常，系统会判定该请求大概率来自自动化黑客工具，从而直接卡死验证。 4. 地理位置与行为“瞬移” 如果你的代理客户端开启了“负载均衡”或“定时自动切换节点”，可能会导致前一分钟请求来自日本，后一分钟请求来自美国。这种超越物理极限的“空间瞬移”属于高风险异常行为。此外，如果通过代码 瞬间改变 窗口尺寸，而非人类拖拽时产生的连续 resize 事件，也会被风控脚本捕捉到异常。 二、 实战优化：如何彻底摆脱“无限验证”死循环？ 要彻底解决或缓解这个问题，可以根据实际的使用场景，从 节点筛选 、 路由分流 以及 浏
