Do We Actually Need Fable 5? A Reality Check on Frontier AI
Now that Fable 5 is open to the public again, I decided to jump back in and start tinkering. So, what are my conclusions after spending hard-earned cash on tokens? Are Fable 5's responses good? Yes, of course they are. Granted, that is a complex claim to make, so let me break down how I am looking at it. To figure out if the cost is justified, the real question you have to ask is: What is your end goal? Are you building a full front-to-backend web or mobile app? Are you tackling a complete websi

SQL: Normalização e Formas Normais
Introdução Imagine uma planilha onde cada linha de um pedido guarda também o nome do cliente, o email, a cidade, o nome do produto e a categoria — tudo junto. Funciona no começo. Mas conforme o sistema cresce, começam a aparecer problemas silenciosos: dados duplicados, inconsistências difíceis de rastrear, operações que quebram coisas inesperadas. A normalização existe para eliminar esses problemas sistematicamente. Proposta por Codd nos anos 1970 e formalizada ao longo das décadas seguintes,

Data Manipulation Language (DML)
Introdução DML é o conjunto de comandos que os usuários e aplicações usam no dia a dia: consultar, inserir, atualizar e deletar dados. Se o DDL define o esquema, o DML é o que acontece dentro dele ao longo de toda a vida do sistema. SELECT O comando mais usado em SQL. Consulta dados de uma ou mais tabelas. SELECT nome, email FROM clientes WHERE criado_em>= '2024-01-01' ORDER BY nomeASC; O SELECT é composto por cláusulas que se encaixam numa ordem lógica: Cláusula Função FROM Define d

Data Definition Language (DDL)
Introdução DDL é o conjunto de comandos responsável por definir e modificar a estrutura do banco de dados: criar tabelas, alterar colunas, remover objetos. Operações DDL geralmente são irreversíveis — um DROP TABLE não pede confirmação, ele simplesmente executa. CREATE TABLE Cria uma nova tabela com suas colunas, tipos de dados e restrições. CREATE TABLE clientes ( id INT PRIMARY KEY, nomeVARCHAR(100) NOT NULL, emailVARCHAR(150) UNIQUE, criado_em DATE DEFAULT CURRENT_DATE ); Neste e

I Turned My Football Group Chat Arguments Into an Actual Scoreboard!
This is a submission for Weekend Challenge: Passion Edition Called It! is a social football prediction platform. You predict match outcomes before kickoff, earn points based on how accurate you were, and compete with friends. No squad management, no transfers, no budgets. Just your ability to read a game. The problem is something I've felt for years. I have a group chat where we all throw out predictions before big matches. Someone says 2-1 with a specific goalscorer. Someone else says 3-0. Then

RNAValidate: CPU-only validator for AI-predicted 3D RNA structures
RNAValidate: CPU-only validator for AI-predicted 3D RNA structures A predictor-agnostic linter that checks AI-predicted 3D RNA structures against experimental data (FRET, cryo-EM, SHAPE/DMS probing, designability) — and flags the ones that will hydrolyze before you can measure them. Predictors and designers (AlphaFold-3, RiboSphere, RoseTTAFold-RNA) are plentiful; an open-source, reproducible layer that audits a predicted 3D RNA structure against experimental evidence is not. Validating befor
