# Building Rudel Ratgeber: A Journey with Flutter
When I set out to create the Rudel Ratgeber app, my goal was clear: make learning for the Hundeführerschein (Dog License) as accessible and engaging as possible. Choosing Flutter as our development framework was a pivotal decision that shaped the course of our app's journey.

## Why Flutter?
Flutter's ability to provide a native performance on both Android and iOS with a single codebase was a major draw. This meant we could speed up development and maintain consistency across platforms, crucial for our app which features a robust question bank and an interactive quiz mode to simulate real exam conditions.
In addition to that, I already built a flashcard app using flutter in the past. So I'll be using my past experiences as a basis.

## The Development Experience
The development process was both challenging and rewarding. Utilizing Flutter’s rich set of material widgets, we crafted a user-friendly interface that allows learners to navigate through over 170 multiple-choice questions smoothly. The app supports an adaptive learning environment using a proven card-box system that helps users track their progress and focus on areas needing improvement.

## Interactive Learning Made Simple
One of the standout features developed is the quiz mode, which automatically cycles through questions, offering a dynamic learning experience that mimics the actual exam environment. We also integrated reminders for users to achieve their daily learning goals, enhancing regular study habits.

## Community and Feedback
The feedback from users has been overwhelmingly positive. Many appreciate the ability to learn anytime, anywhere, emphasizing the app's impact on their successful exam preparation. This feedback has been instrumental in refining the app’s features and usability.

## Looking Ahead
Developing Rudel Ratgeber has been a fulfilling experience, largely due to Flutter’s versatile development toolkit. As we plan future updates, the focus remains on enhancing interactive features and expanding our question database to cover more scenarios.

Building this app allowed us to connect with a community of learners and dog lovers and helped us making a difference in their educational journeys.

Setup Github SSH keys (for linux)
Tags: github, ssh
Published: 2024-05-10 11:36:24

## Step by step instruction to setup GitHub SSH Keys and connect you github account to your local linux machine to push changes in your github repository

---

### **Step 1**: **Check for Existing SSH Keys**

Before generating a new SSH key pair, it's essential to check if you already have existing keys. Open your terminal and run the following command:

```bash
ls -al ~/.ssh
```

- Look for files named id_rsa (private key) and id_rsa.pub (public key). If they exist, you can skip the key generation step.

### **Step 2**: **Generate SSH Key Pair**

```bash
ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
```

- Replace "your_email@example.com" with the email address associated with your GitHub account.

- Press Enter to accept the default file location and enter a passphrase if you want extra security.

### **Step 3**: **Start SSH Agent**

```bash
eval "$(ssh-agent -s)"
```

### **Step 4**: **Add SSH Key to SSH Agent**

- Add your SSH private key to the SSH agent by running:

```bash
ssh-add ~/.ssh/id_rsa
```

- If you set a passphrase during key generation, you'll need to enter it here.

### **Step 5**: **Add SSH Key to GitHub**

Now, you need to add your SSH public key to your GitHub account. Display the contents of your public key by running:

```bash
cat ~/.ssh/id_rsa.pub
```

Copy the output and follow these steps :

- Go to your GitHub account settings.
- Navigate to "SSH and GPG keys".
- Click on "New SSH key" or "Add SSH key".
- Paste your SSH public key into the provided field and give it a title.
- Click "Add SSH key".

### **Step 6**: **Test SSH Connection**

To test if your SSH key is set up correctly, run the following command:

```bash
ssh -T git@github.com
```

#### If everything is set up correctly, you'll see a message confirming your connection.

---

**That's it! You've successfully set up SSH keys for your GitHub account on your Linux machine. Now you can clone, push, and pull repositories using SSH without the hassle of entering your credentials every time.**

PS: When you will commit your changes for the first time, you will be asked to enter github configuration details like your name and email address.
Comprendre la logique de la notation Big O
Tags: algorithms
Published: 2024-05-10 11:26:40

Dans le domaine de l'informatique, la performance est souvent un enjeu crucial. Que ce soit pour des applications web ou des algorithmes de traitement de données massives, il est essentiel de comprendre et d'évaluer la performance des algorithmes que nous utilisons. C'est là que la notation Big O entre en jeu.

## Qu'est-ce que la notation Big O ?
La notation Big O est un outil puissant pour analyser la complexité temporelle des algorithmes. En termes simples, elle décrit comment le temps d'exécution d'un algorithme (ou l'espace mémoire qu'il utilise) augmente en fonction de la taille de l'entrée. Plutôt que de fournir une mesure exacte du temps d'exécution, la notation Big O donne une estimation de la croissance de cet temps d'exécution par rapport à la taille de l'entrée, dans le pire des cas.

## Pourquoi est-ce important ?

Comprendre la performance des algorithmes est crucial pour concevoir des logiciels efficaces. En analysant la complexité temporelle à l'aide de la notation Big O, les développeurs peuvent choisir les algorithmes les plus adaptés à leurs besoins, en tenant compte de la taille des données avec lesquelles ils travaillent et des contraintes de temps.

## Comment fonctionne la notation Big O ?

La notation Big O utilise des fonctions mathématiques pour représenter la complexité temporelle des algorithmes. Voici quelques exemples courants :

1. **O(1)** (complexité constante) : Le temps d'exécution de l'algorithme reste constant, quel que soit la taille de l'entrée. Un exemple est l'accès à un élément dans un tableau par son index.

2. **O(log n)** (complexité logarithmique) : Le temps d'exécution augmente logarithmiquement avec la taille de l'entrée. Des exemples incluent la recherche binaire dans un tableau trié.

3. **O(n)** (complexité linéaire) : Le temps d'exécution est proportionnel à la taille de l'entrée. Par exemple, parcourir un tableau pour trouver un élément.

4. **O(n^2)** (complexité quadratique) : Le temps d'exécution est proportionnel au carré de la taille de l'entrée. Des exemples incluent les algorithmes de tri comme le tri à bulles.

5. **O(2^n)** (complexité exponentielle) : Le temps d'exécution double à chaque augmentation de la taille de l'entrée. C'est souvent considéré comme une performance médiocre et peut être prohibitif pour de grandes entrées.



En conclusion , la notation Big O est un outil essentiel pour évaluer la performance des algorithmes . En comprenant la complexité  des algorithmes à l'aide de cette notation, les développeurs peuvent prendre des décisions éclairées sur le choix des algorithmes les mieux adaptés à leurs besoins.

Why does the textarea rows count not decrease when content is removed?
Tags: textarea, autoresize, react, webdev
Published: 2024-05-10 10:52:17

When I don't set the rows to state or textAreaRef.current.rows = calculatedRows, the console log properly increases and decreases the calculatedRows. However, as soon as I set the calculatedRows to the state or textAreaRef.current.rows = calculatedRows, it increases the rows but does not decrease them; it stays at the last calculatedRows.

```
import React, { useState, useRef, useEffect } from "react";
import ReactDOM from "react-dom";
import styled from "styled-components";

const TextArea = styled.textarea`
  padding: 2px;
  resize: none;
  overflow-y: hidden;
  line-height: 1.5;
`;

function App() {
  const [val, setVal] = useState("");
  const textAreaRef = useRef(null);
  const [rows, setRows] = useState(1);

  const resizeTextArea = () => {
    const lineHeight = parseInt(
      window.getComputedStyle(textAreaRef.current).lineHeight
    );
    const calculatedRows = Math.floor(
      textAreaRef.current.scrollHeight / lineHeight
    );
    console.log(calculatedRows);
    setRows(calculatedRows);
  };

  useEffect(() => {
    resizeTextArea();
  }, [val]);

  const onChange = (e) => {
    setVal(e.target.value);
  };

  return (
    <div>
      <TextArea ref={textAreaRef} value={val} onChange={onChange} rows={rows} />
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
```

I expected the number of rows in the textarea to decrease when content is removed, but it only increases. I've tried using setRows(calculatedRows) and textAreaRef.current.rows = calculatedRows to update the number of rows but encountered the same issue.
