No createStore, No combineReducers, No Provider — Setting Up State in 3 Lines
Redux setup is a ceremony. You create a store, compose your reducers into a root tree, wrap your app in a Provider, register middleware, and configure enhancers — all before you write a single line of feature logic. SDuX Vault™ replaces that entire ceremony with two function calls and zero root configuration. Redux Store Ceremony A typical Redux application requires several files and configuration steps before state management is operational. Here is what a minimal Redux setup looks like for a single feature: // store.ts import { createStore , combineReducers , applyMiddleware } from ' redux ' ; import thunk from ' redux-thunk ' ; import { userReducer } from ' ./reducers/userReducer ' ; const rootReducer = combineReducers ({ users : userReducer , }); export const store = createStore ( rootReducer , applyMiddleware ( thunk ) ); // App.tsx — Provider wrapper required import { Provider } from ' react-redux ' ; import { store } from ' ./store ' ; function App () { return ( < Provider store = { store } > < UserList /> < /Provider > ); } That is 20+ lines of configuration across multiple files — and it only covers one feature. Add a second feature and you are back in the combineReducers file, composing another slice into the tree. Add middleware and you are threading enhancers through applyMiddleware . Add DevTools and you are composing composeWithDevTools on top. Every new feature touches the root configuration. Redux Requirement What It Does createStore() Creates the single global store instance combineReducers() Composes feature reducers into a root tree applyMiddleware() Registers middleware (thunk, saga, etc.) Provider Makes the store available to all components via context composeWithDevTools() Enables Redux DevTools integration ⚠️ Warning: Every entry in that table is root-level configuration. Adding a new feature means editing the root reducer composition, possibly the middleware stack, and potentially the Provider hierarchy. Root configuration is a shared depende

Chrome for Developers a Berlino: cosa aspettarsi dall’ecosistema web nel 2026
Tra performance, piattaforma e toolchain: i temi che contano davvero per chi costruisce frontend oggi. Il frontend nel 2026 è diventato una disciplina sempre più “di prodotto”: non basta far funzionare l’interfaccia, serve che sia veloce, stabile, accessibile e misurabile in produzione. E quando l’ecosistema Chrome parla di “connessione” tra developer e piattaforma, il messaggio utile per chi lavora sul web è semplice: capire dove investire tempo per ottenere impatto reale sugli utenti . Di seguito, una lettura pratica dei temi che continuano a emergere come prioritari per chi costruisce applicazioni e siti moderni. 1) Performance: meno benchmark, più realtà La performance non è più un esercizio di ottimizzazione a fine progetto. È un requisito continuo che va gestito con strumenti, metriche e processi. Cosa significa “misurabile” oggi Metriche di campo (real user monitoring) : le prestazioni che contano sono quelle che arrivano dai dispositivi reali, su reti reali. Metriche di laboratorio : restano utili per regressioni e CI, ma vanno interpretate come “segnali” e non come verità assolute. Implicazione pratica Imposta una pipeline dove: le metriche sintetiche bloccano regressioni evidenti (build/PR), le metriche reali guidano le priorità (release e backlog). 2) DevTools: dal debug al controllo qualità Gli strumenti di sviluppo non servono più solo a “trovare il bug”, ma a ridurre il rischio : regressioni di layout, memory leak, risorse inutili, dipendenze pesanti. Abitudini che fanno differenza Profilare prima di ottimizzare: CPU, rete e rendering hanno colli di bottiglia diversi. Isolare i cambiamenti: una variazione di bundling o di immagini può ribaltare il profilo prestazionale più di una micro-ottimizzazione in JS. 3) La piattaforma web continua a crescere (e chiede scelte più consapevoli) La Web Platform oggi offre API potenti, ma la parte difficile non è “usarle”: è scegliere quando usarle.

Introducing Synapse: a deterministic-first, open-source SCA and evidence platform
We just open-sourced Synapse , a governed control plane for software composition analysis, recon, evidence, and reporting. It is built for people who have to scan a dependency tree, prove what they found, and hand over a report that holds up. Site: https://synapse.kkloudtarus.net/ Code: https://github.com/KKloudTarus/synapse-ce (Apache-2.0) Why we built it The usual workflow is fragmented. One tool for the SBOM, another for vulnerabilities, a spreadsheet for licenses, a folder of screenshots for evidence, and a report you assemble by hand. Nothing is reproducible, and when a client asks "how do you know this is real," the answer lives in someone's memory. Adding an LLM that writes your findings only makes that worse. We wanted the opposite: fast, but provable. What it is Synapse runs the assessment lifecycle behind one control plane, in Go, clean architecture. A few ideas hold it together: Deterministic-first. Scanning, matching, license classification, and reporting are pure, reproducible Go. There is no model in the report path. Scope-gated execution. Every engagement carries a scope and an authorization window, enforced server-side before any tool runs. Tools run via argument arrays, never a shell string. Tamper-evident evidence. Every artifact is hash-chained and append-only. A broken chain blocks the report. Bounded automation. The optional AI layer only ever proposes. A distinct verifier or a human confirms. The agent can never confirm its own claim. What it does today: SBOM across 15+ ecosystems, multi-source vulnerability detection with risk-based prioritization (KEV, then EPSS, then CVSS), license compliance, reachability, and deterministic reports in CycloneDX, SPDX, SARIF, and OpenVEX. Try it git clone https://github.com/KKloudTarus/synapse-ce.git cd synapse-ce docker compose -f deploy/docker-compose.full.yml up --build # open http://localhost:5173 Or gate CI on real risk: ./bin/synapse-cli scan . --fail-on high .

Performance Testing RAG Applications: Complete Engineering Guide
In this blog post, we will see how to performance test a RAG (Retrieval-Augmented Generation) application properly, covering both speed and correctness, and how to wire both into a CI/CD pipeline so regressions get caught before they reach production. Performance testing a RAG application requires two separate testing gates: one for speed and one for answer quality. Traditional load testing tools measure response times but cannot detect hallucinations, where a model returns fast but factually incorrect answers grounded in fabricated context rather than retrieved documents. The guide demonstrates using k6 for load testing end-to-end latency and DeepEval for evaluating faithfulness and answer relevancy using an LLM-as-judge approach. Both gates are integrated into a GitHub Actions CI/CD pipeline so regressions in either performance or output quality are caught automatically on every pull request before reaching production. If you've come from a JMeter or k6 background like I have, your first instinct with a RAG endpoint is probably to point a load test at it and check response times. That gets you halfway there. A RAG app can return a fast, confident, completely wrong answer, and a plain load test will never tell you that. You need two testing surfaces, not one: performance and quality. This guide covers both, using a single running example throughout: a documentation assistant that answers "How do I run JMeter in non-GUI mode?" against a small knowledge base. Why RAG breaks traditional load testing assumptions A conventional API returns a complete response and you measure the round trip. A RAG endpoint does two expensive things before it answers: it retrieves context from a vector store or search index, then it streams a generated response token by token. That second part matters a lot. A single request can stream hundreds of tokens over several seconds, so "request duration" as a single number hides two very different problems: how long the model took to start answe

Building Retrieval-Augmented Generation (RAG) Systems with LangChain and Pinecone
While LLMs are great, there are some limitations in using LLMs: LLMs can hallucinate, presenting factually incorrect information when they don't know the answers, and their knowledge gets frozen at the time of training. That's when Retrieval Augmented Generation (RAG) addresses both of these problems. It is the process of optimizing the output of the LLM. This article walks through what RAG is, why it matters, and how to build a working RAG pipeline using two of the most popular tools in the space: LangChain , a framework for building LLM-powered applications, and Pinecone , a managed vector database designed for fast similarity search at scale. A typical RAG pipeline has three core steps: Retrieve : When a query is entered, the system searches an external data source (like a vector database) for the most relevant documents. Augment : The system attaches those relevant retrieved documents to the original user prompt. Generate : The LLM reads the appended context and formulates a highly accurate, grounded answer. RAG is popular because it solves practical problems that pure fine-tuning or prompting can't easily solve: Freshness — You can update the knowledge base without retraining the model. Domain specificity — You can ground responses in your company's internal documents, product manuals, or proprietary data. Traceability — Because answers are based on retrieved documents, you can cite sources and reduce hallucination. Cost — Retrieval is far cheaper than fine-tuning a model every time your data changes. Why LangChain and Pinecone? LangChain drastically speeds up AI development. It is an open-source orchestration framework that provides pre-built components to connect Large Language Models (LLMs) to external data, manage memory, and create multi-step workflows. It abstracts away the complex boilerplate usually required to build production-ready AI applications. Pinecone is a purpose-built vector database.

A self-cleaning Product Hunt teaser banner in Blazor WASM — 100 lines, auto-hides after launch, GA4-tracked
I'm launching SmartTaxCalc.in on Product Hunt on Tuesday, 14 July 2026 . It's a 38-tool Blazor WebAssembly tax + finance calculator I've written about here before ( the SEO/schema saga , and dropping mobile LCP from 6-8s to under 2s ). The Product Hunt launch algorithm heavily rewards products that arrive with a real coming-soon follower base — day-of upvotes correlate strongly with pre-launch "Notify me" clicks. My PH page started with 1 follower . I had 9 days to get to 50+. The obvious answer: post on LinkedIn, ask friends, DM your network. All of that has ceilings (you can only ask a favor once). The non-obvious answer that has no ceiling: convert your own organic search traffic into PH followers automatically. This is the ~100 lines of Blazor code that does that, plus the design decisions I made along the way. It's also self-cleaning — after the launch date, the banner disappears with no manual work required. Steal the pattern for your own launch. The problem SmartTaxCalc gets modest but real organic traffic — mostly from Google Search Console impressions on tax-season queries. That traffic is the warmest possible audience for a PH launch (they already found the site, they're in the target demo). But how do you route them to a PH page without: Disrupting the tax content (they came for a tax calculator, not a marketing pitch) Cannibalizing the existing tax-season banner (which drives users to /tax-calendar/ — a real retention lever) Leaving code debt after 14 July (a dead PH banner still on the site in September) Losing the dismiss preference across page navigations (SPA reality — no page refresh) Those constraints ruled out a modal, a full-width interrupt, and a "hardcoded remove after launch" approach. The design Slim horizontal bar at the top of every page. Sits ABOVE the existing tax-season banner. PH-brand orange, different from the tax-season banner's yellow/red so both are visually distinguishable when stacked. Dismissible per-user via localStorage . Auto

Como servir os 68 milhões de CNPJs da Receita com ~10ms de latência em Go
Todo dev brasileiro que já precisou consultar CNPJ conhece o dilema: ou você usa uma API que faz proxy da Receita (3 a 10 segundos por consulta, quando não cai), ou baixa o dump de dados abertos e monta a própria base — e descobre que "baixar um CSV" era a parte fácil. Eu montei a própria base. Este post é o diário honesto do que funcionou, do que quebrou e dos números reais — 217 milhões de linhas servidas em ~10ms de p50 dentro do datacenter, num Postgres de 1 vCPU. A arquitetura em uma frase Não consulte a Receita em tempo real. Ingira o dump mensal e sirva da sua infra. O resto é decorrência. Receita (dump mensal, ~6GB zip) ──▶ ingestão Go (COPY) ──▶ Postgres ──▶ API (chi) CGU (CEIS/CNEP, zip diário) ──▶ job diário ──┘ O dump da Receita: as pegadinhas que ninguém documenta O layout oficial existe, mas o que quebra parser de verdade é o que está fora dele: Encoding latin1 (ISO-8859-1) — acento vira lixo se você ler como UTF-8. Em Go: charmap.ISO8859_1.NewDecoder() num transform.Reader streaming. Decimal com vírgula ( "1000000,00" ) e datas YYYYMMDD onde 0 e 00000000 significam nulo. CNPJ quebrado em 3 colunas (básico 8 + ordem 4 + DV 2). A chave de junção entre empresas, estabelecimentos e sócios é o básico — errar isso custa um dia. As partições 0–9 não se alinham entre arquivos. O estabelecimento da partição 3 pode ser de uma empresa da partição 7. Foreign key rígida entre as tabelas = COPY quebrando no meio da carga. A solução: sem FK; a integridade vem da fonte. Bytes NUL ( 0x00 ) no meio dos dados. O Postgres rejeita NUL em text . Um strings.ReplaceAll(s, "\x00", "") no parser economizou três recargas.
