Solid steel programming: blockchain and hardware programming
Published: 2024-02-28 14:19:57

There are notable similarities between programming for hardware devices and programming for blockchain. Both operate within defined constraints and exhibit a deterministic nature. In hardware programming, one must work within the limitations of available energy and memory, acknowledging and adhering to these constraints. Similarly, blockchain programming faces constraints such as the upper gas limit, which restricts the number of computational steps that can be executed, with each step incurring a cost.
Solidity, the programming language for smart contracts on Ethereum, occupies a unique position within the realm of programming languages and technology. It blends the flexibility and expressiveness typical of Turing-complete languages, enabling the implementation of complex logic, with the robustness and rigidity characteristic of hardware programming. This amalgamation of flexibility during development and resilience in production gives rise to new kind of programming. Strange and interesting beast....

OpenCommit: feature-rich CLI to generate meaningful git commit messages now supports local models via Ollama 🤯🔫
Tags: productivity, opensource, git, ai
Published: 2024-02-28 14:01:39

![OpenCommit logo](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/gf9b8a2qdfipahoz1cm9.png)
Hi

OpenCommit is a CLI to generate commit messages, you can try it right now by running `npx opencommit` in any repo you have changed code in. I suggest you use `bunx opencommit` (install [Bun](https://bun.sh)) or install OpenCommit globally `npm i -g opencommit` and then run `oco` which is a shorthand.

Anyway see the README: https://github.com/di-sukharev/opencommit

OpenCommit got 5k stars since the launch. More than 1 hundred PRs have been merged and now we support local Ollama!
![Ollama logo](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/i3uh1zkso0qtpzt6xh6y.png)
Originally OpenCommit worked with OpenAI apis, but if you dont want to share your code base with 3rd party you can now use an LLM running locally, including Mixtral8x7B, llama and other open-source models.

All the latest OpenAI models are also supported if you want to trade your money for the best performance.

Anyway, OpenCommit is the most feature-rich CLI to generate git commit messages out there, i mean in the open-source.

We support tens of different languages, you can integrate opencommit into a git hook, there is a GitHub Action that can improve all the commits in a repository, you can do Conventional Commits and GitMoji, integrate with commitlint, and lots of other things!

We also got first place in DIY Deployments Track in the latest [GitHub+Dev 2023 hackathon](https://dev.to/devteam/github-dev-2023-hackathon-winners-announced-236o)

Set it up yourself: https://github.com/di-sukharev/opencommit

String Vs StringBuffer Vs StringBuilder in Java 💪
Tags: java, programming, programmers
Published: 2024-02-28 13:58:03



String, StringBuffer, and StringBuilder are three classes used for string manipulation, but they differ in terms of mutability, synchronization, and performance characteristics:

## String:

- **Immutable:** Once a String object is created, its value cannot be changed.
- **Thread-safe:** Immutable strings are inherently thread-safe.
- **Memory efficiency:** Because strings are immutable, modifying them (e.g., concatenation) creates new string objects, potentially leading to memory overhead, especially in scenarios with frequent string manipulation.
- Suitable for scenarios where the value of the string remains constant or changes infrequently.

## StringBuffer:

- **Mutable:** StringBuffer objects can be modified after creation.
- **Thread-safe:** StringBuffer methods are synchronized, making them safe for use in multithreaded environments.
- **Performance:** Slower than StringBuilder due to synchronization.
- Suitable for scenarios where thread safety is required, such as in multithreaded applications or when concurrent access to strings is necessary

## StringBuilder:

- **Mutable:** StringBuilder objects can be modified after creation.
- **Not thread-safe:** StringBuilder methods are not synchronized, making them unsuitable for concurrent use in multithreaded environments.
- **Performance:** Faster than StringBuffer because it lacks synchronization overhead.
- Suitable for single-threaded scenarios where high-performance string manipulation is required, such as string concatenation within loops or when building strings dynamically.

```

public class StringExample {
    public static void main(String[] args) {
        // Example of String
        String str = "Hello";
        str += " World"; // Concatenating " World" to the original string
        System.out.println("String: " + str); // Output: Hello World
        
        // Example of StringBuffer
        StringBuffer stringBuffer = new StringBuffer("Hello");
        stringBuffer.append(" World"); // Appending " World" to the original string
        System.out.println("StringBuffer: " + stringBuffer.toString()); // Output: Hello World
        
        // Example of StringBuilder
        StringBuilder stringBuilder = new StringBuilder("Hello");
        stringBuilder.append(" World"); // Appending " World" to the original string
        System.out.println("StringBuilder: " + stringBuilder.toString()); // Output: Hello World
    }
}
```

Here's a summary of their characteristics:
![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/omuq961rt3bt8rdo7j12.png)

In summary, String is immutable and thread-safe, StringBuffer is mutable and thread-safe, and StringBuilder is mutable but not thread-safe. You should choose the appropriate class based on your specific requirements for mutability, thread safety, and performance.
Apple Announces PQ3
Tags: encryption, watercooler, security
Published: 2024-02-28 13:51:49

Since I just finished my [series on encryption](https://dev.to/wolfmath/series/22067) I thought this news was interesting.

Apple just announced its new encryption protocol for iMessage called PQ3. This new protocol was created in order to future proof itself against quantum computing and its impending ability to break our current encryption methods. PQ3 is similar to the Signal protocol and is apparently even more secure. As with Signal it appears to be based on [Diffie-Hellman](https://dev.to/wolfmath/diffie-hellman-public-key-cryptography-1031) and [RSA](https://dev.to/wolfmath/encryption-part-3-rsa-encryption-11g6). 

[Here is Apple's overview](https://support.apple.com/en-us/102651), and here is a [security analysis of how it works](https://security.apple.com/assets/files/Security_analysis_of_the_iMessage_PQ3_protocol_Stebila.pdf), but a lot of that is even beyond me.

Published: 2024-02-28 13:35:18

Hi

The following is a demonstration on how to debug using debugger. Of course, IO.inspect works. Where it does not. 

```
defmodule Math do
  def add(a, b) do
    a + b
  end
end
```

```
defmodule MathTest do

  # timeout: :infinity is needed as the exunit timeouts around 3 seconds 
  @tag timeout: :infinity
  test ~c"test add" do
    :debugger.start()
    :int.ni(Math)
    # break_in take module, function, arity
    # module - Math
    # function - add
    # arity - 2 no of parameters
    :int.break_in(Math, :add, 2)
  end
end
```
React 19: um compilador para chamar de seu – entenda
Published: 2024-02-28 13:30:31

Olá! Então, você quer saber mais sobre React Compiler? Tem motivo: essa parada já está, segundo os devs do Meta, compilando todo o front-end de uma das maiores redes sociais do mundo, o instagram.com. A equipe do React está se preparando para lançar seu próprio compilador para o mundo no React 19, que deve ser anunciado em maio, e, cara, isso vai chacoalhar o mundo do desenvolvimento.

### O Problema do Re-Render no React

Tudo surgiu no re-render. Explico: sabe quando você muda alguma coisa no seu app React e ele decide atualizar mais coisas do que deveria? Isso acontece, né? Você não está só. Desde o começo, a galera do React vem sugerindo usar coisas como `useMemo`, `useCallback`, e `memo` para controlar isso. Mas, convenhamos, isso pode virar uma bagunça e dá um trabalhão para manter e otimizar – de novo, você não está sozinho nessa...

### O Problema da falta de um compiler

Sem o React Compiler, nós desenvolvedores enfrentamos o desafio de manualmente ter que checar e refatorar coisas para melhorar a performance dos aplicativos React, uma tarefa complexa devido à natureza dinâmica e às regras frouxas do JavaScript. É por isso que o React Compiler surge como uma solução inovadora: ele deve otimizar o código ao modelar as regras do JavaScript e do React, garantindo que os componentes sejam idempotentes* (ou seja, sempre retornam o mesmo resultado se os inputs forem os mesmos) e não mudem props ou estados. Ele tenta compilar código de forma segura, adaptando-se às práticas do desenvolvedor e _pulando a compilação quando necessário para evitar efeitos colaterais_.

### O Que é Esse React Compiler?

A ideia do React Compiler é tipo: "Deixa comigo! Eu cuido dessa otimização pra você". Ele pega seu código e dá uma boa _tunada_ para evitar esses re-renders desnecessários. É como se ele automatizasse todo o processo de memoização de forma elegante e precisa, e quem já automatizou sabe: automatização boa é de máquina (escritora) para máquina (leitora) a gente pode focar em supervisionar o process. Quão daora é isso?

### Por Que Isso é Daora?

- Performance: Menos atualizações desnecessárias significam um app mais rápido e responsivo.
- Código Limpo: Você pode focar em escrever seu código sem se preocupar com otimizações complicadas.
- Vida de Dev Melhorada: Menos dor de cabeça com performance significa mais tempo para criar coisas incríveis.

### Se Preparando para o React Compiler

Quer entrar nessa onda? Ative o Modo Estrito e ajuste o ESLint do React. Assim, você já vai estar alinhado com as melhores práticas e pronto para quando o Compiler estiver disponível para todos.

E aí, quer ver o Compiler em ação? Dá uma olhada na apresentação que a equipe do React fez. Eles até usaram o Compiler no Instagram, então já temos uma ideia de como isso pode ser um game-changer.

> *Em matemática e ciência da computação, a idempotência é a propriedade que algumas operações têm de poderem ser aplicadas várias vezes sem que o valor do resultado se altere após a aplicação inicial.
