Courses that explain how things work inside

Every lesson goes beyond the command. It shows the mechanism, why it fails and how to fix it, with a practice environment open beside the text.

SQL do básico ao avançado / Aula 1

Ordem lógica de execução

O banco executa o SELECT em quinto lugar, por isso o apelido ainda não existe no WHERE.

SELECT preco*1.1 AS novo
FROM produtos
WHERE novo > 100;
column "novo" does not exist
Engenharia de software / Aula 3

Nomes apontam, não copiam

y = x não cria outra lista: os dois nomes apontam para o mesmo objeto.

x = [1, 2, 3]
y = x
y.append(4)
print(x)
[1, 2, 3, 4]
Álgebra linear para IA / Aula 6

Projeção de um vetor

A sombra de v sobre u: o quanto um vetor anda na direção do outro.

projuv = v · u / ‖u‖² u
Estatística para IA e ML / Aula 2

A média engana

Um único valor extremo arrasta a média. A mediana quase não se move.

mediana 3,1média 5,4
Desenvolvimento com IA / Aula 4

Palavras viram vetores

Um embedding transforma texto em números. Textos parecidos ficam próximos.

cos(emb("rei"),
    emb("rainha"))
cos(emb("rei"),
    emb("tijolo"))

the approach

Deep does not mean longer. It means the course answers why.

  1. The mechanism, not just the command

    Every concept comes with its cause: why a query fails, what the system is doing at that moment and how to fix it.

  2. Practice beside the text

    Every example opens an executable panel: a SQL console, code editor or calculation notebook, depending on the area.

  3. Diagrams that move

    What is difficult to imagine becomes an animation: a query flow, a vector being projected or a network propagating a signal.

how a lesson works

Two modes on one screen: read calmly, practice without leaving it

In reading mode, text fills the column. In practice mode, the executable panel opens beside it and examples enter with one click. Your last run is saved when you return to reading.

Reading

Text, figures and animations at the pace of the explanation.

Practice

Write, run and check the exercise without changing screens.
