Short answer: For an ask-your-docs semantic search app, batch document indexing, estimate token spend before rollout, and send chat only the top retrieved chunks; that keeps RAG cost under deliberate control. I build RAG and agent features in Python, even when the serving app is Node.js, because I want the eval harness close to the retrieval experiments. The language boundary is rarely the budget problem. Prompt shape is. Start by treating every uploaded document as an ingestion job: split i...

Eu tenho um padrão de publicação estranho. Cinco artigos em quatro meses. Depois sete meses de silêncio total. Três artigos em cinco semanas. Depois quase três meses de silêncio de novo. Um artigo. E aqui estou eu, tentando entender o que esse padrão realmente significa antes de simplesmente prometer "vou postar toda semana" e repetir o ciclo. Entre abril e julho de 2025, escrevi sobre os fundamentos: um plano de estudos de engenharia de plataforma, os sinais de que uma infraestrutura precisa...

In March 2026, OpenAI acquired Promptfoo — the tool that 350,000 developers use to evaluate and red-team OpenAI's own models. I don't think that makes Promptfoo suddenly useless. But it made me ask a question I should have asked earlier: who is the eval tool accountable to? Most LLM eval frameworks — DeepEval, Ragas, LangSmith — have something in common. They all route scoring through an LLM API call. That means your eval pipeline has at least three dependencies you don't control: the tool...

You can give Claude access to your Telegram in about five minutes. Whether that is a good idea depends entirely on which of two very different setups you pick — and most tutorials do not tell you there are two. I went through the available Telegram MCP servers while writing a setup guide, and the gap between them is much bigger than the feature lists suggest. The two kinds, and why it matters MCP — the Model Context Protocol — is the standard that lets AI clients call outside ...

One DNS record covers the whole box: *.example.com → 203.0.113.10 . I set it once, and publishing a service has not involved DNS since. I pick a name, and the name already resolves. What's left is a form in Nginx Proxy Manager (NPM) with four fields that matter: the domain, the container name, the container port, and a checkbox that requests a certificate. That is the whole act of publishing. Fill it in, save, and the hostname is serving HTTPS from a container that was never exposed to any...

If your API exposes /users/1042 , someone can request /users/1043 . And /users/1044 . Sequential integer IDs leak two things you probably didn't mean to leak: roughly how many records you have, and a trivial way to walk through all of them. arxid fixes that. Feed it an integer, get back an unpredictable-looking code; feed the code back with the same key, get the integer. Keyed, reversible, and byte-for-byte identical across every language it's ported to. // Rust let a = ...

A few months ago I got tired of every calorie tracker either paywalling basic features or demanding I create an account just to log a banana. So I built Nawtch — a free fitness tracker that runs entirely in your browser, stores everything locally via IndexedDB, and never asks you to sign up. Here's the messy, honest version of how it actually came together. It didn't start as "Nawtch" The app was originally called Foop. I got pretty far into building it before doing a basic search and r...

Suppose you have a directory full of text documents. Most are repetitive, padded with boilerplate, or otherwise low-signal. A few contain the useful material. You could read every file manually, feed them all into an embedding pipeline, or ask an LLM to rank them. Or you could ask gzip . The basic idea is simple: Repetitive text compresses well. Varied text usually does not. That makes compression ratio a crude but surprisingly useful proxy for redundancy. It will not tell...

How to Turn an Unreliable Protocol into One You Can Trust When most developers think about networking, they immediately think of TCP . After all, TCP powers web browsing, APIs, databases, email, and countless distributed systems. It guarantees that data arrives in order, without duplication, and without corruption. But there's another protocol that quietly powers some of the fastest systems in the world. UDP. Online multiplayer games. Live video streaming. Voice-over-IP....

Week 3. "The artifact is sitting in the registry. Somebody still has to actually run it. Who, and how?" Previously Developer ↓ Runner ↓ Cache ↓ Artifact Today ↓ Deployment Junior Engineer: So the image is built, tagged, sitting in the registry. What's the simplest possible way to actually get it running in production? Senior Engineer: The simplest way is also the most dangerous way. Want to guess it first? Junior Engineer: Stop t...

I have spent the last 18 years working in technology, including around six years as a CTO in startups. Architecture, cloud infrastructure, engineering teams, incidents, and delivery deadlines are familiar to me. This is also my second time as a co-founder, but my role is different now. At CatechLabs, I work across product, sales, customer discovery, positioning, partnerships, and strategy. That shift made something clear: knowing how to build software is not the same as knowing how to b...
