How does compression resistance and content hugging is related?
Tags: ios, swift, frontend
Published: 2023-05-30 10:14:09

Compression resistance and content hugging are two related concepts that work together to determine how a view behaves when its available space is constrained.

Compression resistance: Compression resistance refers to a view's ability to resist being compressed or made smaller when there is limited space available. When a view has a high compression resistance priority, it indicates that it should try to maintain its size and avoid being compressed. This means that if there is not enough space to accommodate all views in a container, the views with higher compression resistance will be less likely to be squeezed or made smaller.

Content hugging: Content hugging, on the other hand, refers to a view's preference for hugging its content tightly. When a view has a high content hugging priority, it means it prefers to be sized to fit its content more closely. Views with high content hugging priority will try to expand to fit their intrinsic content size.

The relationship between compression resistance and content hugging is as follows:

1. Compression resistance takes effect when there is limited space available and views need to be compressed or made smaller to fit within the container. Views with higher compression resistance priorities will be less likely to be compressed compared to views with lower compression resistance priorities.

2. Content hugging takes effect when there is excess space available, and views need to expand to fill the container. Views with higher content hugging priorities will be more likely to expand to fit their intrinsic content size compared to views with lower content hugging priorities.

So, in summary, compression resistance determines how views behave when there is limited space, and content hugging determines how views behave when there is excess space.

By adjusting the compression resistance and content hugging priorities of views within a layout, you can control how they respond to changes in available space and ensure a desired layout and appearance.

The Pros and Cons of Python
Published: 2023-05-30 09:06:03

Hello, there! Welcome to the post!
In this post, I will talk about the many **pros and cons** of _Python_!    
```bash
sudo apt-get install python3.6
```
If you are a **Ubuntu** or **WSL** Python dev, you should remember typing the command above. You would know about `pip` as well.    
Now, should we start?   

## The Pros
The main point of Python is that it is **_simple_** and **_expandable_**.    
But what does this mean? It basically means that Python can do many various stuff, without having to learn other languages for that part. For example, you could use `java` for Android app development, but if you are planning a smaller project, you would be better off with Python. On the other hand, while developing more advanced projects, you should go handy with `java`.
## The Cons
In **The Pros**, we talked about why Python is a good language. We also went into the cons a bit, the fact that Python isn't really suitable for highly-advanced projects.    
     
### Summarizing
> This short post described the basic pros and cons of Python. I will see you in my next post!
Comment faire un système de backup de sa base des données avec sequelize et express.js
Tags: javascript, node, sequelize, backup
Published: 2023-05-30 09:05:17

Pour mettre en place un système de sauvegarde automatique de la base de données avec Sequelize et Express.js, vous pouvez suivre les étapes suivantes:

#### - Installez les modules nécessaires:

```bash
npm install sequelize sequelize-cli mysql2
```



#### - Créez un dossier "backups" à la racine de votre application, et un fchier server.js
Définissez une fonction qui exécutera la sauvegarde dans votre fichier "server.js" :

```js
const Sequelize = require('sequelize');
const spawn = require('child_process').spawn;
const sequelize = new Sequelize('example_db', 'root', '', {
 host: 'localhost',
 dialect: 'mysql',
 operatorsAliases: false,
 pool: {
 max: 5,
 min: 0,
 acquire: 30000,
 idle: 10000
 }
});
function backup() {
 const fileName = `backup-${Date.now()}.sql`;
 const mysqldump = spawn(`mysqldump`, [
 ` - user=${process.env.DB_USER}`,
 ` - password=${process.env.DB_PASSWORD}`,
 ` - host=${process.env.DB_HOST}`,
 process.env.DB_NAME
 ]);
 mysqldump.stdout.pipe(fs.createWriteStream(`./backups/${fileName}`));
 mysqldump.on('exit', () => {
 console.log(`Backup saved at ./backups/${fileName}`);
 });
}
setInterval(backup, 86400000); // sauvegarder une fois par jour
```

Dans cet exemple, nous avons utilisé la fonction spawn() de Node.js pour exécuter le processus de sauvegarde de la base de données et stocker le résultat dans un fichier .sql.
Notez également que nous avons utilisé un intervalle de temps pour exécuter la sauvegarde une fois par jour. Vous pouvez ajuster cela en fonction de vos besoins.



#### - Lancez votre application :


```shell
node server.js
```



#### - Vérifiez les fichiers de sauvegarde dans le dossier "backups" à la racine de votre application.


Ceci est un exemple simple de la mise en place d'un système de sauvegarde automatique de la base des données avec Sequelize et Express.js.
À bientôt, Cedric karungu

Bottle
Tags: bottle, python, auth
Published: 2023-05-30 09:02:48

Bottle is a really small python-based framework. The whole its code takes 1 file with ~4000 rows. Meanwhile, Bottle is pretty self-sufficient - it supports:

- wsgi-server
- routing
- authorization
- plugins
- own templates language
- a lot of extensions (mostly one-paged too)
- custom error pages
- and much more!

I was excited trying to write my blog using Bottle. The first issue I faced - you can login, but you can't logout :D

Bottle supports basic auth mechanism, so you can do something like:

```python
def auth_callback(user, password):
    return user == password  # or any check you want

@bottle.auth_basic(auth_callback)
def edit_post(db, post_id):
    ....
```

But there is no way to logout. The only workaround I found is to return 401 status as a response. It allows to force logout the user. It's not quite correct, because user doesn't expect to get 401Error on logout, but this is why it's called workaround.

To make the solution to look more pretty I also customized 401 Error page, by adding an html-template with link to login.

```python
def logout():
    return bottle.abort(401)

@app.error(401)
def error_401(error):
    return bottle.template("errors/401")

app.route("/logout/", ["GET"], logout)
```

As alternative, there is an extension for bottle, called bottle-login, which has been archived few years ago.

Beginner's Guide to CRUD Operations in Apache age
Tags: apacheage, database, crud, cyphe
Published: 2023-05-30 08:22:21

Cypher is a query language specifically designed for querying and manipulating data in graph databases like Apache age. It provides a simple and expressive syntax for performing CRUD operations (Create, Read, Update, Delete) on graph data. 
In this blog post, we will explore how to use Cypher to perform CRUD operations and provide examples to help you understand and apply these operations in your graph database workflows.

**Create:**
Creating nodes and relationships is a fundamental part of working with graph databases. In Cypher, you can create nodes using the CREATE clause and relationships using the `CREATE `clause along with the `-[RELATIONSHIP_NAME]-> `syntax.

Here is an example

```
CREATE (node:Label {property1: value1, property2: value2})
CREATE (node1)-[:RELATIONSHIP]->(node2)
```

**Read:**
Reading data in Cypher involves querying the graph database to retrieve nodes, relationships, or specific patterns. The `MATCH` clause is used to specify the pattern to match, and the `RETURN` clause is used to specify what data to retrieve. 

Here is a few examples:

```
MATCH (node:Label)
RETURN node

MATCH (node1)-[:RELATIONSHIP]->(node2)
RETURN node1, node2

MATCH (node:Label)
WHERE node.property = value
RETURN node
```

**Update:**
Updating data in Cypher involves modifying existing nodes or relationships. The `SET` clause is used to update properties of nodes or relationships. 

Here is an example:

```
MATCH (node:Label)
WHERE node.property = value
SET node.property = newValue
```

**Delete:**
Deleting data in Cypher involves removing nodes or relationships from the graph. The `DETACH DELETE` clause is used to delete a node and its relationships, or you can use the `DELETE` clause to delete a node without deleting its relationships.

Here is an examples:

```
MATCH (node:Label)
WHERE node.property = value
DETACH DELETE node

MATCH (node:Label)
WHERE node.property = value
DELETE node
```

**Conclusion:**
CRUD operations are essential for managing data in graph databases, and Cypher provides a powerful and intuitive syntax for performing these operations in apache age. In this blog post, we explored how to use Cypher to perform CRUD operations, including creating nodes and relationships, reading data from the graph, updating existing data, and deleting nodes and relationships. By mastering these operations, you'll be equipped to work effectively with graph databases and harness the full potential of Cypher for data manipulation.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8g06uwizyxhuzmxxt1lu.jpeg)**Artificial Intelligence (AI)** is the development of computer systems that's due to the availability of large amounts of data, increased computing power, and the development of advanced algorithms. This has led to a growing interest in the potential applications of AI across a wide range of industries, from healthcare to finance and beyond.

One area where AI has already made significant strides is in natural language processing. This is the ability of computers to understand and interpret human language. With advances in machine learning, AI can now recognize speech patterns and translate languages with a high degree of accuracy.

Another application of AI is in the field of image recognition. With the help of deep learning algorithms and neural networks, computers can now accurately identify objects within images and videos. This has numerous applications, including facial recognition, object recognition, and even identifying diseases based on medical images.

In the field of robotics, AI has enabled the development of intelligent machines that can interact with humans in a natural way. From simple chatbots to more complex humanoids, robots are becoming increasingly common in fields such as manufacturing, healthcare, and education.

However, there are also concerns around the use of AI. One of the biggest issues is the potential for AI to replace human workers in certain industries, leading to job losses and economic inequality. There are also concerns around the ethics of using AI in areas such as autonomous weapons and surveillance.

In conclusion, AI is a rapidly evolving field with numerous applications and potential benefits. However, it is important to carefully consider the ethical implications of its use and ensure that it is used for the greater good. With the right policies and regulations in place, AI can be a powerful tool for improving our lives and solving some of the world's biggest challenges.

## Using brew in a multi-user system

On a mac brew can get into a bit of a muddle on a multi-user system if you are not careful.  The problem is that brew installs everything in `/usr/local` and if you have multiple users then the permissions can get a bit messed up.  The answer to this is to install brew as normal for the first user, but any subsequent users shouldn't install their own version, but run the first users installation instead.

To do this, set up an alias in your **~/.zshrc** to run brew as that user.


```bash
# ~.zshrc
unalias brew 2>/dev/null
brewser=$(stat -f "%Su" $(which brew))
alias brew='sudo -Hu '$brewser' brew'
```

Lets break this down.  The first line removes any existing alias for brew. This is because we need to 'real' brew in the second line to find the installation location (**which brew**).

The second line gets the user that brew is installed under.  The third line creates an alias for brew that runs brew as the user that brew is installed under.  The `2>/dev/null` just stops an error message if there is no existing alias (which we would get on the first sourcing of the file as in that instance brew would be the 'real' brew).
