Have you heard of containerized GPU data centers? A beginner's guide to how they work

📝 Originally published (in Japanese) at forge.workstyle.tech . In this article, we'll explain what a data center is and how containerization changes the game. We'll also explore the relationship between GPUs and liquid cooling, as well as the various usage options. By the end, you should be able to explain how containerized data centers work to others. No prior knowledge of GPUs or data centers is required. What Exactly is a Data Center? A server is a computer ...

Node.js Login Endpoint Protection — A Credential-Stuffing API and Lockout Policy

For a small gaming SaaS team, the least complex defensible approach is to protect the signup and login API with a captcha after a few failed attempts, then require step-up verification when risk persists. Do not lock the account. A lockout lets an attacker deny service to any player whose email address is known. TL;DR: Use per-account and per-network failure signals to decide when to show a captcha, but do not turn either signal into a permanent identity verdict. After the captcha, require an...

LGPD e dados pessoais na IA

Resposta curta A Lei Geral de Proteção de Dados (LGPD) aplica-se integralmente ao tratamento de dados pessoais por sistemas de inteligência artificial no Brasil, exigindo base legal, transparência, impact assessment quando relevante e responsabilização do controlador — mesmo quando a IA opera de forma autônoma ou com decisões automatizadas. TL;DR A LGPD entrou em vigor em 18/09/2020, com sanções aplicáveis desde 01/08/2021 (Lei nº 13.709/2018, art. 52). Dados pessoais in...

IBM Granite Guardian: o motor do guardrail

Resposta curta O IBM Granite Guardian é um guardrail técnico nativo do modelo IBM Granite, projetado para detectar e mitigar conteúdos de risco em tempo real — como discurso de ódio, desinformação ou violação de políticas — sem comprometer a fluidez da geração. Ele opera como uma camada de segurança integrada, não como um filtro pós-geração. TL;DR O Granite Guardian é parte integrante da arquitetura dos modelos IBM Granite (v3, v4), não um módulo externo. Funciona com ...

Drawing a Git commit graph that stays narrow: lane layout in TypeScript and SVG

If you've looked at a commit graph for a repo with a few long-lived branches, you've seen this: every branch gets its own column, columns never go away, and eventually the graph is wider than the commit messages next to it. I ran into this while building the history view for a desktop Git client. The first version gave each line its own column for good. On one 122-commit repo that came to 14 lanes, 276px of graph before any text. This post covers how I rebuilt the layout so lanes get reused, ...

X-COM: UFO Defense — The 1994 Strategy Classic That Taught the Industry How to Lose

January 1st, 1999. The planet is yours to defend, and your first act as commander of X-COM is picking a spot on a map for your first base. No tutorial. No walkthrough. Just a spinning globe, sixteen nervous governments, and the knowledge that somewhere in the dark, Sectoids are already moving. X-COM: UFO Defense — known in Europe as UFO: Enemy Unknown — shipped in 1994 from a tiny British studio called Mythos Games, led by Julian Gollop. It was nearly cancelled twice during development. Then ...

Node.js Error Grouping API: US/EU Event Detail for B2B SaaS

For a small B2B SaaS comparing Rollbar, Bugsnag, Sentry, or a lean alternative, a useful server error grouping API must let the on-call search one property-management attempt, inspect event detail, and resolve workflow state without losing the underlying evidence. The least complex design is one immutable event stream keyed by an attempt ID, plus error groups that point back to those events across US and EU workloads. The bad page says only agent_error_rate > 5% . An engineer opens it at ...

The Power Apps Code App Licensing Trap Nobody Tells You About

If you're building a Power Apps Code App (React + TypeScript + Dataverse), there's one requirement that can kill an otherwise finished project: every end user needs a Power Apps Premium per-user license. Not a per-app license. Not a free tier. A Premium license, per person, for every single user who will open the app. This sounds obvious once you say it out loud - but it's easy to miss during scoping, especially when the business asks for "an app for everyone in the company." I've...

Roteamento multi-LLM na prática: 16 modelos, escada de complexidade e FinOps que dispara

TL;DR (English). geo-orchestrator routes each task of a natural-language request across 16 LLMs from 5 providers by task type, complexity, cost and provider health. Every task type keeps a fallback chain whose top two slots come from different vendors; the two frontier models (US$ 10/50 per million tokens) sit behind a declarative policy with a 35% per-session share cap; and FinOps enforces per-run, per-day and per-provider ceilings with alerts that actually fire. State as of Oct 7, 2026: 23 ta...

A minimal TypeScript implementation of SAL flows

Protocol ideas become much easier to reason about once they are visible in code. SAL, the Sovereign Agent Lifecycle Protocol, is still evolving, but the basic flow is straightforward enough to show in a small TypeScript sketch: an agent generates its own keypair, initializes into orphan state, proves possession through challenge-response, and later requests short-lived scoped access. The public spec is at sal-protocol.dev , and the reference implementation is in Vibebase . This is not...

Why a Financial Advisor App Needs a RAG Vault, Not Just a Chatbot

When I started building Vicquant, the core design principle was simple and non-negotiable: the AI never does the math. Every number and a debt payoff schedule, a backtested win rate, a risk metric is computed by deterministic code. The model's only job is to explain results in plain language, never to generate a number from scratch. That principle protects users from one kind of failure: a model confidently inventing a wrong calculation. But it doesn't protect against a second, quieter failu...

Before building an MVP, give one workflow a clear purpose

A feature list tells you what software might contain. A clear purpose tells you what someone should be able to do with it. Before deciding what belongs in an MVP, try writing one sentence: When [situation occurs], [person] needs to [complete a task] so they can [reach a useful outcome]. Consider a hypothetical neighborhood repair shop: “When a customer asks about a repair, the person at the counter needs to find its current status so they can give a useful answer.” That sentence...

Show HN: VoiceGremlin, a SaaS tool for automated tests against AI phone agents

Hi, I'm a former SDET and now solo dev of VoiceGremlin, a tool for automated tests against AI that answer phones. You pass the API a phone number and a test case like "Verify that the agent does X." It calls your voice agent, tests the thing by having the bots talk to each other, and uses LLM-as-judge to provide a pass/fail for your pipeline. State: Fully working, free trial, no card needed. Try it out and please give me feedback, especially if you run in to problems. Goal: I built VoiceGreml...
