Note to myself:

Life is too short to waste with null pointer exceptions, undefined is not a function, ...

Just use Elm for the frontend.

A gentle reminder that contemporary neural networks are only an abstraction built upon Boolean logic

And that said neural networks are only an echo of a whisper of what organic neurons are.

The workshops I saw presenting "spec driven development" works exactly like this:

Phase 1: write specs.
Phase 2: ?????
Phase 3: the most beautiful code* base you ever saw in your life!

If this is the future of programming, I don't wanna be a part of it anymore. I don't wanna be a "prompt engineer". I don't care if it's "much faster" this way.

And I really fear what kind of shitty softwares we will be running on our computers a few years from now.

Quando foi isso com o conceito de mock e li o paper do Nat Pryce que foi um dos primeiros a propor a ideia, abriu muito minha cabeรงa para vรกrios dos problemas que eu via sobre como o conceito era aplicado na prรกtica vs o que ele foi concebido para ser

Pode ser.

Acho que vejo mais algo como Imperativo vs Declarativo.

Mesmo Dart (que รฉ basicamente OO) quando usada com Flutter acaba tendo uma abordagem mais declarativa (e - atรฉ certo ponto - meio similar a essa ideia de "joga tudo fora e constrรณi novamente" na camada da view).

Nรฃo sei dizer. Talvez. Mas no MVC a view em geral รฉ stateful nรฉ?

Acho que a quebra de paradigma de vocรช olhar apenas para o model atual, gerar a view como ela deveria ser para este model e a runtime que se vire (no caso de elm com dom virtual + diffs) pra tornar isso realidade, รฉ bom demais hehe <3

Just saw a Java class (jdk 25) defined as something like this:

@Getter
@Setter
@Builder
public class XPTOModel {
private String system;
private String service;
private String clientVersion;
private String language;
private String release;
private String systemVersion;
}

"What Lin and Cursor achieved was to show that an AI agent can generate millions of lines of code thatโ€™s lifted from other projects, and that donโ€™t compile, let alone work."

Cursor lies about vibe-coding a web browser with AI

The @swift.org team is demonstrating a level of consistency that makes me believe they really want to see the Swift programming language thrive outside of the Apple ecosystem.

Just found out that if you create a .noai in the root of your project, IntelliJ will disable it's AI features for that project ๐Ÿ‘€

Generated a bunch of code. But never ran/compiled it.

In the end of the presentation he asked the agent to run the front end.

It took nearly 30 minutes trying to compile it without success and that was the end of the presentation.

โ€œSpec driven developmentโ€ is a hoax.

Saw a presentation about a โ€œspec driven developmentโ€ the other day. The dude promised the world. Every question was answered with โ€œsure it can do that! Easy peasy!โ€.

Iโ€™m glad my feed here is not that toxic.

Every time I try to upgrade dependencies in a Java/Spring project, I remember how freaking easy it was to upgrade dependencies in a Clojure + Elm project and wonder why people donโ€™t f*ing value that.

No wonder we have so many freaking obsolete Java projects around. Itโ€™s such a pain in the butt.
