Google's Genkit Ships Agents API with Detached Turns and Human-in-the-Loop for TypeScript and Go

Google released the Genkit Agents API in preview for TypeScript and Go. The open-source framework packages message history, tool loops, streaming, and state persistence behind a single chat() interface. Detached turns let agents work after clients disconnect. Interruptible tools provide human-in-the-loop control with anti-forgery validation on resume. By Steef-Jan Wiggers

Migrating a Vite i18n App to Next.js Without Breaking Everything

The Architecture Shift: SPA vs. Framework Internationalization (i18n) is one of those features that feels straightforward in a Single Page Application (SPA). You install react-i18next , wrap your app in a provider, and you're good to go. However, when you decide to migrate that Vite-based React app to Next.js for better SEO and performance, the strategy for i18n changes fundamentally. In a Vite SPA, i18n is typically client-side. In Next.js, i18n happens at the routing and server level. If you don't plan the migration carefully, you'll end up with hydration mismatches, flashing text, or broken search engine indexing. Here is how to navigate the transition. 1. Defining the Routing Strategy In Vite, your translations often live in the same bundle, and you swap them out using a state hook. Next.js, particularly with the App Router, prefers sub-path routing (e.g., /en/about or /es/about ). This is crucial for SEO because it allows search engines to crawl localized versions of your pages individually. Instead of relying on localStorage to remember a user's language, you should now rely on the URL. Most teams moving from Vite use a middleware approach to detect the user's preferred locale and redirect them to the correct sub-path. 2. Choosing the Right Library If you were using react-i18next in your Vite project, you have two main paths in Next.js: next-i18next (Pages Router): The traditional choice for the Pages Router. next-intl or i18next + i18next-resources-to-backend (App Router): These are modern solutions that leverage Server Components. When handling complex migrations involving many components, using a specialized tool like ViteToNext.AI can help automate the transformation of your Vite project structure into a Next.js-ready architecture, saving you hours of manual refactoring. 3. Handling Server Components vs. Client Components one of the biggest hurdles is that useTranslation() hooks from standard i18n libraries are "Client hooks." In the App Router, you'll wan

Diagnosing Cloudflare Blocks Before Changing Your Scraper

A scraper fails, someone swaps the User-Agent, someone else adds a proxy, then the job starts passing locally but fails again in CI. That usually happens because Cloudflare did not block “scraping” as one thing. It evaluated several signals, and each failure needs a different fix. This is about authorized automation: your own sites, customer-approved workflows, testing, monitoring, data access you are allowed to perform. If you do not have permission to automate against a site, changing fingerprints or rotating IPs does not make it okay. Start with the failure you actually see Cloudflare failures often get collapsed into “403”, but the page body matters. Common cases: Error 1020 : usually an access denied page from a Cloudflare rule or bot score decision. The HTTP status may still be 403, so inspect the HTML. 403 without a 1020 page : often IP reputation, firewall rules, geo restrictions, or an auth problem. 429 : rate limit exhaustion. Slowing down can help here, but it will not fix a fingerprint problem. Endless Just a moment... page : your client did not complete the browser-side challenge. CAPTCHA or Turnstile loop : Cloudflare still considers the session borderline after earlier checks. Add classification before you add workarounds. Even a basic classifier saves time: import time import requests CLOUDFLARE_MARKERS = { " 1020 " : " cloudflare_access_denied " , " Just a moment " : " cloudflare_js_challenge " , " cf-turnstile " : " cloudflare_turnstile " , " cf-error-code " : " cloudflare_error_page " , } def classify_response ( resp : requests . Response ) -> str : body = resp . text [: 5000 ] if resp . status_code == 429 : return " rate_limited " for marker , label in CLOUDFLARE_MARKERS . items (): if marker in body : return label if resp . status_code == 403 : return " forbidden_unknown " return " ok " if resp . ok else f " http_ { resp . status_code } " def get_with_backoff ( url : str , max_attempts = 4 ): for attempt in range ( max_attempts ): resp = request

Stop Arguing About Code Style — Set Up Prettier, ESLint & Husky Once

Why this matters I’ve worked on a few frontend projects where code reviews turned into style debates—tabs vs spaces, semicolons, quote styles… you name it. It slows everything down and adds zero value. At some point, I realized this shouldn’t even be a discussion. So now, whenever I start a project, I set up Prettier + ESLint + Husky on day one. No debates. No manual fixes. No messy PRs. This post is exactly how I do it. 🧰 What each tool actually does Prettier → formats your code automatically ESLint → catches bad patterns & enforces rules Husky → runs checks before commits (so no one skips them) Together → clean, consistent code without thinking ⚙️ Step 1 — Install dependencies npm install -D prettier eslint husky lint-staged 🎯 Step 2 — Setup Prettier Create: prettier.config.js module . exports = { semi : true , singleQuote : true , trailingComma : ' all ' , tabWidth : 2 , }; Create: .prettierignore node_modules dist build 🔍 Step 3 — Setup ESLint Initialize: npx eslint --init Then tweak your config: .eslintrc.js module . exports = { extends : [ ' eslint:recommended ' , ' plugin:react/recommended ' , ' prettier ' ], rules : { ' no-unused-vars ' : ' warn ' , ' react/react-in-jsx-scope ' : ' off ' , }, }; 👉 Important: "prettier" disables ESLint rules that conflict with Prettier. 🔗 Step 4 — Connect ESLint + Prettier Install: npm install -D eslint-config-prettier That’s it. Now ESLint won’t fight Prettier. 🐶 Step 5 — Setup Husky Initialize Husky: npx husky init Add pre-commit hook: npx husky add .husky/pre-commit "npx lint-staged" 🚀 Step 6 — Setup lint-staged Add to package.json : "lint-staged" : { "*.{js,jsx,ts,tsx}" : [ "eslint --fix" , "prettier --write" ] } 💡 What happens now? Every time you commit: ESLint checks your code Prettier formats it Only clean code gets committed No more: “fix formatting” PR comments broken lint rules in main branch inconsistent code styles 🧠 Real impact (from experience) After adding this to a team project: PR noise dropped a lot reviews

Making ServiceLoader usable: a provider factory

I keep coming back to java.util.ServiceLoader . I have used it to put a JSON layer behind a contract, so the core code carries no direct dependency on any particular JSON library and I can swap the implementation without touching callers. The same shape works for JWT handling, where the concrete library might be jose4j or another JOSE implementation, and you can easily find other decoupling use-cases. The motivation is always the same: the application should depend on a capability, not on a vendor. A while back I wrote about exactly that idea in Rediscovering Java ServiceLoader: Beyond Plugins and Into Capabilities , where the argument was to treat ServiceLoader as capability discovery rather than a plugin system. That piece hit the limitation everyone hits — the no-argument constructor — and worked around it with a default constructor plus a dynamic proxy that built the real object through a factory on each call. It works, but it is indirection bolted on after the fact, not a design. This post is the part I never pinned down back then: turning that workaround into a small, explicit pattern. The running example below is a mock payments system, with Stripe and PayPal specializations, because it is compact enough to show end to end. The JSON and JWT cases cited can be built with the same structure. The two limits ServiceLoader leaves you The first is the no-argument constructor. Whatever ServiceLoader instantiates must have a public, parameterless constructor. My StripePaymentService takes an API key, so it cannot be the class ServiceLoader loads — not unless I bolt on some init-after-construction step, which I would rather avoid. The second is selection, or rather the lack of it. ServiceLoader gives you every implementation it finds, in roughly classpath order. There is no id, nothing to prioritise on, and no way to ask whether a given one even applies in the current environment. With two backends on the classpath and only one configured, working out which to use is

The Right Way to Start Claude Code on an AWS Project

You know the drill for adding an MCP server to a project: dig the exact command string out of the docs, hand-write a .mcp.json with an absolute path you'll typo once, restart the editor, and discover no tools showed up because the server expected a config file you haven't created yet. Plenty of MCP servers lose their would-be users somewhere inside that loop. Infrawise collapses the whole loop into one command. It's an open-source tool ( npm ) that statically analyzes your codebase, AWS infrastructure, and database schemas, then exposes that context to AI coding assistants over MCP — so Claude Code knows your actual partition keys, GSIs, and indexes instead of guessing from source files. This post is about the part that usually kills tools like this before they deliver any value: setup. Section 1: One command, four steps npm install -g infrawise # or skip install and use npx cd your-project infrawise start --claude start does four things, in order: 1. Probes your environment. If there's no infrawise.yaml in the project, it generates one. It reads AWS_PROFILE if set; otherwise it looks at your configured AWS profiles — one profile means zero questions, several means one prompt asking which to use. That's the entire interview. (If you want the full guided wizard instead, infrawise start --interactive runs it.) 2. Runs the analysis. It scans your AWS services, database schemas, and codebase, builds a graph of services, tables, indexes, and query patterns, and runs rule-based analyzers over it. No LLM is involved in this step — extraction and analysis are deterministic, so the same infrastructure always produces the same graph. 3. Writes .mcp.json to your project root. This is the file you'd otherwise write by hand: { "mcpServers" : { "infrawise" : { "command" : "infrawise" , "args" : [ "serve" , "--stdio" , "--config" , "/absolute/path/to/infrawise.yaml" ] } } } 4. Opens Claude Code. Claude Code reads .mcp.json automatically and starts the session with all 21 infrawise

7 MongoDB Query Mistakes That Return the Wrong Results

MongoDB queries look simple. You type a field, give it a value, hit run, and you get your data back. But just because a query runs without throwing an error doesn't mean it worked right. Sometimes you get a blank screen. Sometimes you get way too many records. Other times, the data looks fine at first glance, but it doesn't actually match what you asked for. Most of these slip-ups happen for one basic reason: the query structure doesn't match the way the data actually sits in the database. To show you what we mean, we’ll use a clinic database with a collection called visits . Here is what a typical document looks like: JSON { "_id": "6871b6f9c3f1d1a4c2a10001", "status": "completed", "visitDate": "2026-07-01T09:30:00.000Z", "patient": { "name": "Anna Keller", "age": 34 }, "doctor": { "name": "Dr. James Carter", "specialty": "Cardiology" }, "symptoms": ["cough", "fever"], "prescriptions": [ { "name": "Ibuprofen", "active": false }, { "name": "Paracetamol", "active": true } ], "invoice": { "paid": true, "method": "card", "total": 250 } } You can run these examples right in the VisuaLeaf MongoDB Shell . Using visual tools makes a big difference because you can see exactly what MongoDB is returning in real time. 1. Forgetting the Curly Braces This is just a quick typo, but it breaks things right away. The Mistake: db . visits . find ( status : " completed " ) The Correct Query The find() tool always expects an object. Even if you are only looking for one specific thing, you still need to wrap that condition in curly braces {} . 2. Treating $or Like a Regular Object This one trips a lot of people up because the broken version looks like it should work. The Mistake: db.visits.find({ $or: { status: "completed", "invoice.paid": false } }) What is wrong: $or expects an array of conditions, but this query gives it one object. The error will usually be something like: MongoServerError: $or must be an array The Correct Query The first query is wrong because $or needs an array, n

Four Eras of Cloud Security. Same Verb.

✓ Human-authored analysis; AI used for formatting and proofreading. Scott Piper published a twenty-year retrospective on cloud security research in March 2026. It's the most useful structural history of the field I've seen — four eras, each with defining milestones, each with the tools and research that shaped cloud security. If you work in cloud security, read it first. What follows is a question about what the history reveals when you examine one detail it doesn't discuss. The four eras Piper divides two decades into four eras: 2006–2016, Foundational. Cloud providers built the security primitives — IAM (2011), CloudTrail (2013), Organizations and SCPs (2016). Before these existed, there was no mechanism for least privilege, no audit trail, and no organizational boundary. Security research in this era was part-time work from people with broader careers. 2016–2021, CSPM. Cloud security became a full-time job. CIS Benchmarks standardized what to check. Open-source tools proliferated — Prowler, CloudMapper, Pacu, Cloud Custodian, ScoutSuite. Cloud security during this time largely meant deploying a CSPM. 2021–2025, CNAPP. Point solutions gave way to platforms. Vendors integrated CSPM with container scanning, vulnerability management, and workload protection into a single product category. Research teams at vendors began finding cross-tenant vulnerabilities in the cloud providers themselves. 2025–present, AI. AI accelerates both attack and defense. Exploits that required deep language expertise are generated in minutes. A CTF challenge was solved by an AI within minutes of release. The industry is speed-running the cloud eras. This is a well-evidenced narrative. Every era is defined by a change in what tools could do and who was building them. The verb that didn't change Look at what each era's defining tools do. The direct action each tool performs on its direct object. In the CSPM era, the defining tools match API responses against rule databases. Prowler, ScoutSuit

Article: Comprehension at AI Speed: Building a Context Store for Evolutionary Architecture

AI makes the first 80% of development feel fast, but hides architectural complexity until it's too late. To prevent system instability, engineering leaders must shift from raw throughput to systemic comprehension. By unifying spec-anchored SDD, TDD, and automated fitness functions into a repo-bound "Context Store," teams can ensure AI agents and human reviewers evolve code safely.
