In the vast landscape of cybersecurity, authentication stands as the guardian of digital fortresses, ensuring that only the right individuals gain access to sensitive information and services. Imagine you're at the entrance of a top-secret facility, and you need to prove your identity to the security personnel. In the digital realm, this is precisely what authentication mechanisms do – they verify your identity before granting access.
When it comes to databases, making sure that the right programs have access is super important for keeping things safe and organised. At first, I thought databases might use a method called **JWT tokens** for this because it's popular and strong for security. However, I found out that there are different ways of authentication based on the connection state.
**- Token Based Authentications:** Token-based authentication is a method where users or applications receive a special "token" after initial authentication. This token is then used for further requests without repeatedly verifying credentials for each new connection.
Due to this property, it is used in the **Stateless Services** (like REST APIs, SSO, etc)
**- Connection oriented Authentications:** It is a method where users authenticates with the credentials for each connection or session. It is typically used in scenarios where a continuous connection or session is established between the client and server (like Databases, SSH).
In this blog post, we will explore how to mock SCRAM authentication in a testing environment. Before we dive into the details, let's first understand what SCRAM (Salted Challenge Response Authentication Mechanism) is and how it is used by databases like MongoDB.
**What is SCRAM authentication**
SCRAM, which stands for "Salted Challenge Response Authentication Mechanism," is a powerful challenge-based authentication method that follows the SASL (Simple Authentication and Security Layer) framework. SASL is designed to provide a framework for authentication and security without exposing sensitive credentials like passwords during the authentication process. This helps with several important aspects of authentication and security in the digital world:
**- Password Protection:** In SCRAM, the password is not shared between the client and server which ensures the security of user password. This also prevents from the MITM attacks.
**- Protection Against Credential Attacks:** SCRAM is resistant to common credential-based attacks such as brute force and dictionary attacks. The salted and hashed passwords, along with challenge-response mechanisms, add a layer of complexity that makes it challenging for attackers to guess passwords.
**- Confidentiality:** SCRAM ensures the confidentiality of sensitive data during authentication. By using cryptographic techniques and secure channels, it prevents unauthorised entities from eavesdropping on authentication attempts.
**- Secure Access Control:** SCRAM plays a crucial role in access control, ensuring that only authorised users or applications can interact with a system or database.
`There is a good example on wikipedia describing scram. here`
**How SCRAM authentication works**
After exploring what SCRAM is and understanding its purpose, it's natural to wonder how it functions and ensures all the necessary properties for ideal authentication in database environments.
In SCRAM authentication, the client and server securely establish their identities without the need to exchange the user password. This is achieved by generating and validating cryptographic proofs. These proofs are created using robust cryptographic algorithms, such as HMAC and SHA-hashing. This method ensures that even if network packets are intercepted by an intruder, the **password remains undecipherable.**
As the generation and validation of proofs in SCRAM authentication rely on randomly generated nonces by the client and server, it ensures robust security against potential intruders. The key factor here is that for each new connection, a unique nonce is generated and associated with it. This dynamic and one-time use of nonces effectively mitigates the risk of packet capture leading to unauthorised access, enhancing the overall security of the communication process.
Here is a detailed flow of communication for SCRAM authenticaton.
**Challenges for mocking SCRAM Auth**
In a test environment, mocking libraries need to bypass authentication simply by returning a message indicating successful authentication. However, SCRAM introduces a more complex scenario. In SCRAM, the client not only authenticates itself but also verifies the server's identity, adding an additional layer of security. This dual-verification process presents a significant hurdle for mocking tools like Keploy, an API testing tool designed to capture and replay network data. Due to SCRAM's complex nature, these libraries often experience Auth failure error like:
```
Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='USER', source='ADMIN', password=<hidden>, mechanismProperties=<hidden>}; nested exception is com.mongodb.MongoSecurityException
```
Upon debugging the network packets, we've identified key insights. Attached below are the pertinent packet details for reference:
```
# SaslStart request. Here, r is the client nonce.
n,,n=root,r=hjO1c6p6PaNbeDUGhn/Jak3FFuUZQBxN1xmOeWr5L1c=
# The mocked SaslStart response. Here, r is the client/server nonce.
r=cjr1a0k0KanfoMMNkr/LaedRRtTQUBxM4fe3tuc6K1d=/igGE0M3BBiDmR/et9DN4cOR+CoNtHxs,s=ZPGEqaD8ImD95Vt3c1uuVQkImxrntgG4Wjh37Q==,i=15000
```
In the mechanism under discussion, the r key plays a crucial role in transmitting nonces within the payload. During the process, the client initiates the interaction by sending a new client nonce within the request. Subsequently, it receives a combined client/server nonce, along with the salt and iteration count, in the SaslStart response. However, a notable issue arises here: the client nonce often does not match in the response payload of SaslStart. This mismatch is a critical point of concern, as it can disrupt the intended flow of the SaslContinue authentication cycle because client and server proof depends on the nonces.
**Nonce Syncing: A Quick Fix for Successful auth**
To bypass the nonce mismatch issue during SCRAM authentication in Keploy tests, a straightforward solution is to update the client nonce directly in the SaslStart response payload. This adjustment ensures that the client's nonce matches the server's, leading to successful authentication. Attaching the pseudo code:
```
func (saslStartRequest, saslStartResponse string) {
expectedNonce, err := extractClientNonce( saslStartRequest )
actualNonce, err := extractClientNonce( saslStartRequest )
// Since, the nonce are randomlly generated string. so, each session have unique nonce.
// Thus, the mocked server response should be updated according to the current nonce
return strings.Replace( saslStartResponse, expectedNonce, actualNonce, -1), nil
}
```
`Here is the code in production to update client nonce.`
After implementing the quick fix of replacing the client nonce, we anticipated a smooth resolution. However, the error persisted, leading us to delve deeper into the problem. Further investigation required debugging the client driver, where we uncovered a critical issue: the server verification was failing on the client side.
**Final step: Correct Server Proof Generation**
In tackling SCRAM authentication issues with Keploy, the critical final step is ensuring the correct generation of server proof. This is essential for successful authentication, especially with how the client side works.
1.**Client-Side Verification:** The client uses the combined client/server nonce to verify the server. The method to generate the server proof, which is key to this verification, is straightforward yet precise.
2.**Why Authentication Fails:** Our tests showed that authentication failures were mainly due to the mismatch between the recorded server proof and the new nonces. Each new nonce combination requires a unique server proof, and if they don't match, authentication fails.
3.**Fixing the Issue:** The solution is simple: generate a new server proof for each new set of nonces. This means moving away from using a fixed, recorded proof to creating a new proof every time, based on the current nonces. This change solves the authentication problems and ensures that the client can successfully verify the server each time, making the process more secure and reliable.
The image below provides a detailed description of the formula used in generating server proofs:
Here, is the code in production for generating the server proof in SaslContinue
`Hurray! Our fixes worked – authentication is now a smooth success in our test environment! 🎉🎊`
**Conclusion**

1.**SCRAM Auth Insights:** We've learned how SCRAM auth secures user verification without revealing passwords, a smart way to safeguard user credentials.
2.**Mocking Library Challenges:** Mocking tools (like Keploy), reliant on network packets, face hurdles with SCRAM due to its dynamic and secure nature.
3.**Solution for Testing:** To successfully test with mocking libraries, it's essential to configure them with the user's password. This allows for generating accurate server proofs, aligning with the ever-changing nonces in SCRAM.

1,863,809 | Destructuring Assignments in JavaScript | Destructuring in JavaScript lets you easily take apart arrays or objects and assign their parts to... | 0 | 2024-05-24T10:13:37 | https://dev.to/linusmwiti21/destructuring-assignments-in-javascript-5hik | javascript, webdev, beginners, programming | Destructuring in JavaScript lets you easily take apart arrays or objects and assign their parts to new variables. It's like unpacking a box: instead of grabbing each item one by one, you can quickly grab what you need all at once. This makes your code easier to read and write because you can do more with less.
There are two main types of destructuring in JavaScript:
1. **Array Destructuring:** With array destructuring in JavaScript, you can grab values from an array and assign them to variables in just one go. Plus, if you don't need certain values, you can easily skip over them.
2. **Object Destructuring:** With object destructuring, you can extract properties from objects and assign them to variables with the same name. You can also provide default values in case the property doesn't exist in the object.
Destructuring help increase the readability, decrease verbosity, and improve maintainability of your Javascript code.
In this article, we'll take you through destructuring assignments, exploring how to work with both arrays and objects while providing practical examples and highlighting valuable use cases. Additionally, we'll look into advanced techniques such as rest operators and combining array and object destructuring to demonstrate the full power and flexibility of this JavaScript feature.
### Destructuring Objects
Object is a basic data structure in JavaScript that is used to arrange data in a key-value pair manner. It functions similarly to a container that stores attributes (keys) and the values that go with them. Think of it like a box with sections that are labelled.
**Example**
```javascript
const person = {
name: "Alice", // Key: "name", Value: "Alice"
age: 30, // Key: "age", Value: 30
hobbies: ["coding", "reading"] // Key: "hobbies", Value: Array of strings
};
```
**Data Types for Values:** Object values can be of any data type in JavaScript, including strings, numbers, booleans, arrays, or even other objects (nested objects).
**Accessing properties:** You can use bracket notation (``object["key"]``) or dot notation (``object.key``) to access particular properties of an object. The value connected to the key is retrieved by both notations.
Objects are a great method to organise related data in JavaScript. They function similarly to labelled boxes, with keys serving as labels that identify certain values (the contents therein). The key-value pair method facilitates efficient data access and manipulation. Moreover, objects serve as the foundation for complex data structures and can even be used to represent actual objects in JavaScript programmes.
**Accessing Object Properties using Destructuring**
Destructuring in JavaScript isn't just for retrieving values from regular objects. It also lets you reach and access properties from objects hidden inside other objects. Now let's see how we may effectively access object properties by using destructuring syntax.
Imagine a scenario where an object is designed to represent a user:
```javascript
const user = {
name: 'John Doe',
age: 30,
email: 'john@example.com'
};
```
To access the individual properties of this object, we can use destructuring assignment:
```js
const { name, age, email } = user;
console.log(name); // Output: John Doe
console.log(age); // Output: 30
console.log(email); // Output: john@example.com
```
**Nested Object Destructuring**
Objects in JavaScript can hold other objects within them, creating a hierarchy of data structures.
Often, objects may contain nested structures, such as:
```js
const user = {
name: "Patel",
age: 40,
address: {
city: "Mumbai",
country: "India",
},
};
```
To access nested properties, we can destructure them directly:
```js
const { address: { city } } = user;
console.log(city); // Output: Mumbai
```
We destructure the user object, extracting the address property and assigning it to a new variable named address.
Within the nested address object, we further destructure to extract the city property and assign it to the standalone variable city.
This approach simplifies object access, especially when dealing with deeply nested structures.
**Renaming Properties**
JavaScript destructuring assignments have a useful feature that allows you to rename properties as you extract them from objects. This can be really helpful:
* The property name in the object doesn't clearly reflect its meaning.
* You want to use a different variable name for clarity or consistency within your code.
**Example**
```js
const person = {
fullName: "John Doe",
age: 30,
};
```
Destructuring allows you to rename the property during extraction. Here, we'll rename ``fullName`` to ``firstNameLastName``:
```js
const { fullName: firstNameLastName } = person;
console.log(firstNameLastName); // Output: John Doe
```
In this example, we separate the individual object.
The property ``fullName`` is specified inside the curly braces {}, and is followed by a colon :.
To capture the value from the ``fullName`` field, we declare a new variable named ``firstNameLastName`` after the colon.
JavaScript's object destructuring completely changes the way we work with complex data. Curly braces are used to extract values from objects directly, eliminating the need for tedious dot notation. Clarity requires renaming attributes on. Destructuring efficiently captures particular data in one go, even with nested objects.
### Destructuring Arrays
An array is a type of variable that has the capacity to store several values. JavaScript's array destructuring makes working with arrays easier by enabling you to extract values directly from the array.
To assign values to variables, use square brackets rather than indexing elements. Selecting specific elements from an array becomes clear-cut and easy. You can also skip elements and define default values during destructuring, which increases flexibility in managing different cases. Ultimately, array destructuring simplifies your code, improving its readability and productivity.
**Accessing Array Elements using Destructuring**
In JavaScript, array destructuring offers a simple method for accessing array elements. Square brackets allow you to assign array values directly to variables, without the need for the conventional index notation.
**Example**
```js
const colors = ["red", "green", "blue"];
// Destructuring the first two elements:
const [firstColor, secondColor] = colors;
console.log(firstColor); // Output: red
console.log(secondColor); // Output: green
```
We destructure the ``shoppingList`` array.
We define two variables: ``firstItem`` for the first element.
For ``secondItem``, we set a default value of "eggs".
If shoppingList only has one element, "eggs" is assigned to ``secondItem`` to avoid undefined.
**Skipping values example**
Sometimes you only need specific elements from an array, and the rest are irrelevant. Destructuring allows you to skip elements elegantly. Simply add commas (,) where you want to skip elements.
**Example**
```js
const colors = ["red", "green", "blue", "yellow"];
const [firstColor, , thirdColor] = colors;
console.log(firstColor); // Output: red
console.log(thirdColor); // Output: blue (skipping the second element)
```
In this case, We destructure the colors array using square brackets [].
We define two variable names, ``firstColor`` and ``secondColor``, separated by a comma.
These variable names automatically capture the values at the corresponding positions (index 0 and 1) in the array.
### Destructuring using the Rest Operator (...)
A function can consider an infinite number of arguments as an array by using the rest operator (...). This operator allows you to capture all the remaining elements of an array into a single variable, after extracting the specific elements you need upfront.
Imagine a shopping list that might have an indefinite number of items beyond the essentials (milk, bread, eggs). Destructuring with the rest operator lets you handle this flexibility with ease. Here's the concept in action:
```js
const shoppingList = ["milk", "bread", "eggs", "chips", "cookies"];
const [firstItem, secondItem, ...remainingItems] = shoppingList;
console.log(firstItem); // Output: milk
console.log(secondItem); // Output: bread
console.log(remainingItems); // Output: ["chips", "cookies"] (all remaining items)
```
We destructure the ``shoppingList`` array.
We extract the first two elements (``milk`` and ``bread``) into separate variables.
The magic happens with the rest operator (``...``). It captures all the remaining elements (``chips`` and ``cookies``) into an array named ``remainingItems``.
The rest operator (... ) in destructuring works when you're dealing with arrays of unknown length. It lets you grab the specific elements you need upfront and effortlessly capture any remaining items in a single variable. This keeps your code concise, adaptable to different array sizes, and ultimately more reusable for various scenarios.
### Conclusion
In JavaScript, destructuring assignments provide a strong and efficient method of working with both arrays and objects. You can greatly increase the readability, maintainability, and flexibility of your code by utilising destructuring techniques.
This article provided a foundational understanding of destructuring, covering:
* Extracting specific properties from objects
* Renaming properties during extraction
* Accessing elements from arrays
* Using defaults and skipping elements in arrays
* Capturing the remaining elements of an array with the rest operator (...)
Even though this is only a brief introduction to destructuring, we've already seen how it simplifies complex data manipulation tasks.
Start incorporating destructuring assignments into your JavaScript coding practices. You'll find it becomes a natural and efficient way to interact with data structures.

When it comes to art and artists, it is important to provide them with the much-needed support and encouragement. Why? It is to bring complex ideas and emotions to life.
Providing the artists with [abstract art awards](https://www.olympia.com.au/corporate/abstract-awards/) is important because it will help provide them with an opportunity to connect with people from the art community. The abstract awards Award will encourage them to showcase their creations. This article will teach us more about abstract art and the importance of providing abstract awards.
## What is Abstract Art?
The work of artists can leave a lasting impact on our minds, helping bring imagination and creativity to the forefront. Abstract art mostly is a reflection of the thought process of the artist itself. It is their innate ability to think beyond the traditional ideas and bring something extraordinary on paper.
Abstract art can be anything from geometric shapes, to just a wide amalgamation of colors. In the truest sense it reflects the inner workings of the artist's minds and brings their thoughts and feelings on the canvas.
## Why do we need Abstract Art Awards?
It is important to hold abstract words because it will allow for better art appreciation. Generally, abstract art is very difficult for most people to understand. Most people find it difficult to understand the context of these paintings, and thus reduce their interest.
Organizing abstract awards, will help educate the masses about this art form along with honoring talented artists in the world. It will take a positive step towards appreciating art for its varied forms and ideas.
It is easier these days to hold abstract awards online to unite the abstract art community and appreciate their talent. Through abstract awards online, it also becomes easier to learn about different new abstract artists and encourage others.
The advantage associated with abstract awards online is that it helps in networking. As artists convene to talk about different techniques and topics leading to the sharing of knowledge. This shows that holding abstract art awards, [sports trophies and medals](https://www.olympia.com.au/corporate/school-trophies/) even if they are abstract awards online, enriches the art community as a whole.
## 1. The case of Emotions
Through the abstract award of art it allows artists to showcase how they use their emotions and intuition to create art. It helps them to make people understand that there is no set way to view abstract art, but rather their own feelings and imagination.
## 2. Challenging Traditional Ideas and Interpretations
Organizing abstract words will allow people to understand the different perspectives and emotions associated with abstract art. It will help provide an opportunity to break down any conventional ideas or views that may be present and help provide a new Outlook. It will allow people to conserve more about abstract artwork, which will lead to better knowledge and understanding.

## Why is Art Appreciation important?
There can be many reasons outlined necessary for holding abstract awards and art appreciation. One should not forget that it provides a historical perspective of different cultures, societies, and the modern world. Hence, having the ability to analyze art will allow an individual to reflect on the problems that were prevalent in society and compare if history has been repeating itself.
By appreciating art and organizing abstract awards, it will be possible to bring the community together to analyze different perspectives of artists, their designs, skilled techniques, and mastery of different hues of colors. Mostly, abstract art awards will provide an opportunity to appreciate art more from emotions, thoughts, and minds rather than what is just being viewed by the eye.
The abstract award will help in the following:
1. Helping create awareness about viewing art more from their heart and emotions than just the mind.
2. Improving their conscience and consciousness to understand the different emotions and perspectives.
3. Through the abstract art awards, it will be possible to create a Foundation for artists to come together and appreciate each other's work.
4. The abstract art awards will also contribute to learning about different stories and reflections on the canvas.
5. Lastly, through the Abstract Award, it will be possible to connect with art on a deeper level and learn the ability to reflect our thoughts and ideas.
## Relevance of Honoring Artistic Excellence
There always lies the question of whether abstract art awards or any awards relating to art are even relevant or not to society. And the answer is that it is indeed relevant.
The reason is that an announcement regarding abstract awards online or about abstract art awards in general creates a positive buzz around the event. This allows people to start learning about abstract awards and understand abstract art, which is usually beneficial to the growth of artists in general.
It is important to understand that art and artists are vital to sustaining a developing and liberal economy. Art allows an artist to express emotions and ideas, this sense of the world, and its many works through abstract patterns. It provides the people with a window not only to the artist's soul but also to the world itself. Hence, it becomes possible to recognize all these facets through the abstract award.
Most importantly, abstract art awards allow abstract artists to hear and see their work. They are allowed a platform to showcase their life's work and be appreciated for the mastery of their ideas and techniques in front of many critics and viewers alike. Abstract awards help them network and connect with like-minded individuals, leading to the community's growth as a whole.

Issue Details:
Issue Number: #149001
Reported by: rkunboxed
Date: 11 hours ago
Comments: 2
Description
Dialogs in Flutter Web are dismissed prematurely when ensureSemantics is included. Clicking inside the dialog on whitespace causes dismissal, contrary to expected behavior.
Issue Report: Dialogs Dismissed Prematurely with `ensureSemantics`
Steps to Reproduce
Run the code sample as a Web project in Chrome.
Click on the "Show Dialog" button.
Click anywhere inside the dialog that is not a form field.
Observe the dialog being dismissed.
Expected Results
The dialog should not dismiss when any content inside it is clicked. It should only dismiss if the area outside the content (the barrier) is clicked.
Actual Results
Clicking on whitespace inside the dialog causes it to be dismissed in Web builds. This only occurs in Web builds and only when WidgetsFlutterBinding.ensureInitialized().ensureSemantics(); is included.
Code Sample
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
WidgetsFlutterBinding.ensureInitialized().ensureSemantics();
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return const MaterialApp(
title: 'Semantics Issue',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key}) : super(key: key);
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
void _onPressed() {
showDialog(
context: context,
barrierColor: Colors.grey.shade400,
builder: (context) {
return _dialogContent;
},
);
}
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
ElevatedButton(
onPressed: _onPressed,
child: const Text('Show Dialog'),
)
],
),
),
);
}
Widget get _dialogContent => Center(
child: Container(
margin: const EdgeInsets.all(50),
child: const Material(
child: SizedBox(
height: 250,
width: 250,
child: Padding(
padding: EdgeInsets.all(20),
child: Column(
children: [
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Form field one',
),
),
SizedBox(height: 40),
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Form field two',
),
),
],
),
),
),
),
),
);
}
Workaround
A workaround is available by wrapping the dialog contents in a Stack and including a hidden Semantics widget inside Positioned.fill().
Widget get _dialogContentHack => Center(
child: Container(
margin: const EdgeInsets.all(50),
child: Material(
child: SizedBox(
height: 250,
width: 250,
child: Padding(
padding: const EdgeInsets.all(20),
child: Stack(
children: [
Positioned.fill(
child: Semantics(hidden: true),
),
const Column(
children: [
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(),
labelText: 'Form field one',
),
),
SizedBox(height: 40),
TextField(

1,863,795 | Scheduling Events in Firebase Firestore with Server Timestamps | Explore how to utilize Firebase Firestore to schedule events with server timestamps effectively, showcasing a practical implementation. | 0 | 2024-05-24T10:00:40 | https://dev.to/itselftools/scheduling-events-in-firebase-firestore-with-server-timestamps-3ccd | firebase, firestore, javascript, webdev |
At [itselftools.com](https://itselftools.com), we have developed over 30 applications using technologies like Next.js and Firebase. Throughout these projects, we have leveraged Firebase's powerful features, particularly Firestore, to handle real-time data management efficiently. In this tutorial, we'll explore how to use Firebase Firestore to add documents with server timestamps, specifically focusing on scheduling events.
## Understanding the Code
The provided code snippet demonstrates how to create a new document in the Firestore database under the collection 'events'. Here’s a breakdown of each part of the code:
```javascript
// Add a document with server timestamp
const db = firebase.firestore();
db.collection('events').add({
name: 'Webinar',
startTime: firebase.firestore.FieldValue.serverTimestamp()
}).then(docRef => {
console.log('Event scheduled with ID: ', docRef.id);
}).catch(error => {
console.error('Error scheduling event: ', error);
});
```
- **firebase.firestore()**: This function initializes the Firestore service.
- **db.collection('events')**: Specifies the 'events' collection where the document will be added.
- **add({...})**: Adds a new document to the collection. The document contains two fields: 'name' and 'startTime'. The 'name' field is a simple string that describes the event, while 'startTime' is a special field that uses `firebase.firestore.FieldValue.serverTimestamp()`, telling Firestore to fill this field with the server's current timestamp at the moment of document creation.
- **.then(docRef => {...})**: This callback function is executed when the document is successfully added. It logs the unique identifier of the document (`docRef.id`).
- **.catch(error => {...})**: If there is any error during the document creation, this callback function captures and logs the error.
## Benefits of Using Server Timestamps
Server timestamps are incredibly useful because they ensure the synchronization of times recorded in the database, regardless of the client's local time settings. This is crucial for applications such as scheduling events, where accuracy and consistency of time are essential across different users and devices.
## Practical Uses
Using server timestamps in event scheduling helps in maintaining consistency across time zones and devices, making the application reliable for users globally. This setup is ideal for various applications like online webinars, meeting schedulers, and appointment booking systems.
## Conclusion
The ability to add events with server timestamps using Firestore is just a glimpse of what Firebase can do to enhance real-time data handling in web applications.

<!-- /wp:heading -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Background</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Whatwapp, founded in Milan in 2013, aimed to reshape classical cultural card games into video games. By 2023, the app had reached 29 million downloads, with 900,000 monthly and 300,000 daily users. As Whatwapp grew, it faced challenges in improving scalability and backend management for its games. The company sought to standardize its game infrastructure to save engineering time, support player retention, and avoid accumulating technical debt. Rewriting feature implementations to share among its games was time-consuming and led to inconsistencies, complexity, and incompatibility. Whatwapp decided to migrate its games' backend solution and unify implementations on AWS through Nakama, an open-source distributed social and near-real-time server for games and apps provided by Heroic Labs, an AWS Partner.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Implementation Steps</h3>
<!-- /wp:heading -->
<!-- wp:heading {"level":4} -->
<h4 class="wp-block-heading"><strong>Standardizing Backend Operations</strong><strong></strong></h4>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Whatwapp aimed to standardize the back-end operations to avoid constant rewrites and maintain compatibility with older versions. The fact that the company had been using the Amazon Elastic Kubernetes Service (Amazon EKS) for its back-end game operations had played a significant role. Whatwapp self-hosted the Nakama solution at its Kubernetes clusters with Amazon EKS to manage the back-end game operation. This setup allowed Whatwapp to share features between the games more efficiently and, therefore, had a third of what would have been needed to implement features using the old method.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":4} -->
<h4 class="wp-block-heading"><strong>Accommodating Scalability and Performance</strong><strong></strong></h4>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>In 2022, Whatwapp successfully migrated its backend operations to Nakama, running on its own Kubernetes clusters using Amazon EKS. This migration enabled Whatwapp to use a scalable server capable of handling 40,000 simultaneous players, providing improved visibility, time savings, and feature enhancements. The power of Nakama on Amazon EKS allowed Whatwapp to identify gaming bottlenecks and underperforming code, enabling targeted improvements to the code base.</p>
<!-- /wp:paragraph -->
<!-- wp:heading {"level":3} -->
<h3 class="wp-block-heading">Enhancing Player Experience</h3>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>With AWS powering its new infrastructure, Whatwapp was able to get content to the players faster than ever before, and without requiring the players to download the updates. This solution significantly enhanced the player's experience, as they could start using almost new stuff the same second it was deployed. The slim infrastructure also made it easy for engineers of Whatwapp to design and share new features, and the solution was better social and exciting competitive gameplay that made the games more attractive.</p>
<!-- /wp:paragraph -->
<!-- wp:heading -->
<h2 class="wp-block-heading">Results and Impact</h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>As the company managed to standardize game infrastructure, they can save on engineering time and reduce technical debts. The scalability and performance were also improved to add more concurrent players, and the usage of lean infrastructure helped content reach players faster, thereby improving retention and satisfaction. Moreover, this has improved the scalability and performance of Whatwapp, allowing the company to host more concurrent players with an improved gaming experience. It will also deliver content faster to increase player retention and satisfaction.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>According to the technical lead at Whatwapp, Giovanni Piumatti, "With AWS powering our new infrastructure, we deliver content to players faster than ever before, and players can use it almost as quickly as we can deploy it, without forcing players to download any updates."</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>Whatwapp has succeeded in integrating AWS and Nakama on Amazon EKS—an integration that has proved how services in the cloud can be used to transform the gaming sector into a scalable, efficient, and player-centric place. This study has demonstrated how prospective cloud computing technologies can support game development and deployment. It also provides evidence for the potential of gaming companies to leverage AWS to innovate in their product and service offerings.</p>
<!-- /wp:paragraph -->
<!-- wp:heading -->
<h2 class="wp-block-heading">Implementation setup </h2>
<!-- /wp:heading -->
<!-- wp:paragraph -->
<p>Use these steps to create something similar through CLI and console to <a href="https://whatwapp.com/">Whatwapp's</a> implementation by a gaming company. This setup involves creating an Amazon EKS cluster, configuring the required IAM permissions, and deploying game server resources using Nakama on Amazon EKS.</p>

title: Think Golang in oop way
published: true
description:
tags: go,golang
cover_image: https://dev-to-uploads.s3.amazonaws.com/uploads/articles/q52tbvcvsr5p2xrifpol.png
---
I began learning Golang for no reason other than it is a highly optimized, low CPU-consuming language that is excellent for creating microservices. It may appear humorous, but I began learning Go because of its adorable logo. 🥰
Anyway, I started learning GoLlang with the intention of creating a highly effective and optimized backend API. I come from the `typescript` environment, where I could arrange my apps in multiple OOP paradigms, something I can't do in the functional world of Golang. I sink into a large body of water. I was looking through various backend libraries to learn how they organize their applications and how they configure/inherit functionality. All I discovered is that I must become a Go pointer master. Using this pointer, I can accomplish OOP capability in this language. That's why I started translating my OOP thinking into a Golang functional approach.
> This article is a Golang translation of OOP ideas.
### Basic Class property, method and it's object
First consider the below typescript code 👇
```js
class Customer {
public identification: string;
private name: string;
private age: number;
constructor(identification:string, name: string, age: number) {
this.identification = identification;
this.name = name;
this.age = age;
}
getName() {
return this.name;
}
getAge() {
return this.age;
}
}
```
#### Declare class and define fields
To translate this class into Golang, we need the struct of Go which is a composite type. we can define properties in a struct with visibility also. This is achieved by a simple rule: if a field starts with a lowercase letter, it's private and can only be accessed within the file it's declared. Conversely, if it begins with an uppercase letter, it's public and accessible from other files.
Here is the translated Customer class with it's public/private fields
```go
type Customer struct {
Identification string
name string
age int
}
```
## How do I create the object of this? 🥹
Cool down, Golang introduces a unique twist to object creation compared to other object-oriented languages. Instead of directly crafting objects like in `TypeScript`, Golang leans on a special convention: using a function named New() to initialize and return a pointer to the newly created struct. This function, starting with an uppercase letter, plays a crucial role in Golang's object instantiation. See the code below ⬇️
```go
func New(id string, name string, age int) *Customer {
return &Customer{
Identification: id,
name: name,
age: age,
}
}
```
Create a Customer object by providing initial values to its constructor. In the following code snippet, only the capitalized fields are accessible, while private fields remain inaccessible.
```go
func main() {
// Initializing a Customer object with constructor values
customer := customer.New("customer1", "Rayhan", 27)
// Accessing a public field
fmt.Print(customer.Identification) //✅
// Attempting to access private fields
// This will result in an error
fmt.Print(customer.name) //❌
fmt.Print(customer.age) //❌
}

They carefully review each commit, ensuring that there are no conflicts and that the new code aligns with the existing codebase. Any discrepancies are flagged and communicated back to the developers for quick resolution.
### Mid-Morning: Automated Testing
By mid-morning, it’s time for automated testing. Like a diligent quality assurance specialist, our CI/CD human runs a series of tests on the integrated code. Unit tests, integration tests, and regression tests are all part of the repertoire. Each test is meticulously executed, and results are promptly analyzed. If any issues are found, the CI/CD human communicates with the relevant developers to get them fixed before the next deployment.
### Lunchtime: Monitoring and Optimization
During lunchtime, our CI/CD human takes a brief break but remains vigilant, constantly monitoring the health of the system. They review performance metrics and logs to identify any potential bottlenecks or areas for optimization. Just like a proactive engineer, they tweak configurations and make adjustments to ensure the pipeline runs efficiently.
### Afternoon: Deployment Prep
The afternoon is dedicated to deployment preparation. Our CI/CD human works like a seasoned operations manager, ensuring that the deployment environment is ready. They verify that all dependencies are in place, database migrations are prepared, and rollback plans are established in case anything goes awry. Communication with stakeholders is key, and our CI/CD human ensures that everyone is aware of the upcoming deployment.
### Late Afternoon: The Big Deployment
As the day progresses, it’s time for the big deployment. With the precision of a skilled technician, our CI/CD human orchestrates the deployment process. They push the code to production, monitoring every step to ensure a smooth transition. Any issues that arise are swiftly addressed, minimizing downtime and ensuring that end-users experience a seamless update.
### Evening: Post-Deployment Checks
After the deployment, our CI/CD human performs post-deployment checks, much like a quality control inspector. They verify that the new features are functioning as expected and that there are no critical bugs. They also gather feedback from users and developers, taking notes for future improvements.
### Night: Maintenance and Learning
As the day winds down, our CI/CD human engages in maintenance tasks. This includes cleaning up old builds, archiving logs, and preparing the pipeline for the next day. They also spend time learning about new tools and technologies, always looking to enhance their skills and improve the pipeline.
### Conclusion: An Indispensable Ally
In the world of software development, a CI/CD pipeline is an indispensable ally, tirelessly working to ensure that code is seamlessly integrated and deployed. If CI/CD pipelines were human, they would embody the qualities of a project manager, quality assurance specialist, engineer, operations manager, technician, and quality control inspector all rolled into one. Their dedication and efficiency would make them the unsung heroes, ensuring the success of every software project they touch. | mitch1009 | |

1,863,784 | Conquering AWS Cloud Resume Challenge | The Cloud Resume Challenge was created by Forrest Brazeal to upgrade and showcase your cloud skills.... | 0 | 2024-05-24T09:47:47 | https://dev.to/madhesh_waran_63/conquering-aws-cloud-challenge-1799 | aws, devops, cicd, cloud | The Cloud Resume Challenge was created by Forrest Brazeal to upgrade and showcase your cloud skills. Completing it requires you to follow a strict set of requirements that will test and challenge your understanding of the cloud.
I did the AWS Cloud Resume Challenge and this is how it went:
## Certification
First, your resume needs to have an AWS certification on it. I got my AWS Cloud Practitioner certificate by using the Stephen Mareek course on Udemy. I think that the course and the accompanying practice test are enough if you get above 80% on your first try. But if you score below 70%, I would advise you to sit through some practice tests on Udemy and not try your hand at the exam till you consistently get an 80% in most of the practice tests you try.
## HTML
Your resume needs to be written in HTML. Not a Word doc, not a PDF. I previously had no idea about HTML except the little I learned in fifth grade and knowing it was an easy language that you can easily pick up. I learned HTML using the w3schools website and the Odin project and made a simple HTML page for my resume.
## CSS
Your resume needs to be styled with CSS. I already had a good idea of CSS since you get an HTML/CSS as a package deal in most of the tutorials you find. I didn’t want to think too much about designing my website, so I just watched a YouTube video for a website resume and styled my page to look exactly like that. I decided that I would redesign my website with my ideas later when I had free time. But this would do for now.
## Static Website
Your HTML resume should be deployed online as an Amazon S3 static website. This was the easiest part with lots of tutorials and a very extensive AWS document that provides a comprehensive guide. So, I easily whipped up an S3 bucket, turned on static website hosting, and uploaded my website files to it. The website endpoint worked fine and this did not require any troubleshooting except me looking through AWS documentation and stack overflow to see if I have given any unnecessary permissions that could threaten my account security.
## HTTPS
The S3 website URL should use HTTPS for security. You will need to use Amazon CloudFront to help with this. This was where I encountered my very first hiccup. I bought a custom domain name from [Namecheap](https://www.namecheap.com/) and wanted it to point to my CloudFront distribution. I was very excited that my domain name only cost a dollar but I fear that the service merits that cheap price. I wanted that lock sign next to my website but I learned that getting an SSL certificate from ACM for my cheap domain would require a whole lot more effort to validate it than if I had purchased from route 53. The process should be easy but since I did not purchase the premium DNS package that lets me manipulate host records, I had to find a sneaky way to validate which I did. This stunted my progress for quite a while but, I persevered and created a custom DNS server for it using route 53 which will be explained in detail in the next process. Aside from getting my SSL certificate from ACM, everything else was a breeze. I quickly set up a CloudFront distribution using my S3 bucket website endpoint as the domain origin. This gave me that sweet https:// locked sign for my site which I wanted very much.
The resource that was very helpful during my troubleshooting process is this doc:
[Alternate Domain Developer Guide](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/using-https-alternate-domain-names.htmlument.
)
## DNS
Point a custom DNS domain name to the CloudFront distribution, so your resume can be accessed at a custom domain name. You can use Amazon Route 53 or any other DNS provider for this. I first created a Route 53 hosted zone which gave me 4 nameservers. I switched my Namecheap DNS with these 4 servers and they were very helpful in creating records to get my DNS validated without falling into the premium DNS trap of Namecheap.
## Javascript
Your resume webpage should include a visitor counter that displays how many people have accessed the site. You will need to write a bit of Javascript to make this happen. Once again, I used the w3schools database to get a feel of the language. I decided to write a simple script that will call the API as soon as the page has loaded and then display the responding data from the API. My code was a bit archaic since I used the XML HTTP function instead of the function that is specifically made for fetching APIs but it seemed to work as it is so I did not change it.
## Database
The visitor counter will need to retrieve and update its count in a database somewhere. I was advised to use Amazon’s DynamoDB for this purpose. Creating the table was straightforward and was finished in minutes.
## API
You should not communicate directly with DynamoDB from your Javascript code. Instead, you will need to create an API that accepts requests from your web app and communicates with the database. I used AWS’s API Gateway and Lambda services for this. This gave me a bit of a struggle as I did not have a single idea of what I was supposed to do. So, I read many documents and watched many videos to understand what it was that I was supposed to do. Once I felt enough confidence in my knowledge of API gateways I decided that I would stumble around and make it work somehow since the AWS official documentation was confusing to me and I decided not to use it. I first experimented with an HTTP API which I felt must be cheaper and got it working. I later switched to using REST APIs as it was easier to deploy with CI/CD integration. Integrating with the Lambda and deploying gave me an API endpoint which I inserted into the Javascript code.
## Lambda
I created a Lambda function to integrate with the API and DynamoDB database. You will need to write a bit of code in the Lambda function to access and update the database. I decided to explore Python – a common language used in back-end programs and scripts – and its boto3 library for AWS. There were many resources available for creating a Python code and I decided to use them as my guidance since I had not used Python before this. Those guides were very extensive and helpful in helping me create my code. [Boto3 for Dynamodb](https://hands-on.cloud/boto3/dynamodb/)
## Infrastructure as Code
You should not be configuring your API resources – the DynamoDB table, the API Gateway, the Lambda function – manually, by clicking around in the AWS console. Instead, define them and deploy them using Terraform. This is called “infrastructure as code” or IaC. It saves you time in the long run. I had no previous experience with Terraform and I went in fresh with only the official documentation as my guide. Even though I had to rewrite my code due to various trial and error methods, every time the code worked it felt like Christmas. It was simple and the official guide is the only thing you need to deploy the entire infrastructure. The error logs were very specific and this helped me not waste my time making unnecessary code changes. It took me three days to write the code to automatically provision all the AWS resources with only the official guide and no other resources.
## Source Control
You do not want to be updating either your back-end API or your front-end website by making calls from your laptop, though. You want them to update automatically whenever you make a change to the code. This is called continuous integration and deployment, or CI/CD. I achieved this by creating a GitHub repository for my backend code.
## CI/CD (Back end)
I set up GitHub Actions such that when I push an update to my Terraform template or Python code, they automatically get packaged and deployed to AWS. This was achieved by this Github action by [appleboy.](https://github.com/appleboy/lambda-action)
## CI/CD (Front end)
Create GitHub Actions such that when you push new website code, the S3 bucket automatically gets updated. I used the s3 sync action resource made by [jakejarvis.](https://github.com/jakejarvis/s3-sync-action)
## Blog post
The final goal of the challenge was to post our experience with this challenge in a blog. I was deciding between Dev.to, Hashnode, and medium as my blog site. I still have goals to create my own blog but I chose dev.to since I felt that I would rather be a part of a close-knit dedicated community than be a part of a large site writing pointless articles to get more and more traffic.

These operations... | 27,505 | 2024-05-24T09:44:48 | https://dev.to/lohith0512/element-wise-numerical-operations-in-numpy-a-practical-guide-with-examples-824 | python, numerical, operations, numpy | Numeric operations in NumPy are element-wise operations performed on NumPy arrays. These operations include basic arithmetic like addition, subtraction, multiplication, and division, as well as more complex operations like exponentiation, modulus and reciprocal. Here are some examples of these operations:
**Addition**:
You can add two arrays element-wise using the `+` operator or the `np.add()` function.
```python
import numpy as np
# Define two arrays
a = np.array([1, 2, 3])
b = np.array([4, 5, 6])
# Element-wise addition
result = np.add(a, b) # or a + b
print(result)
# Output: [5 7 9]
```
**Subtraction**:
Similarly, subtraction is done using the `-` operator or `np.subtract()` function.
```python
# Element-wise subtraction
result = np.subtract(a, b) # or a - b
print(result)
# Output: [-3 -3 -3]
```
**Multiplication**:
For element-wise multiplication, use the `*` operator or `np.multiply()`.
```python
# Element-wise multiplication
result = np.multiply(a, b) # or a * b
print(result)
# Output: [ 4 10 18]
```
**Division**:
Element-wise division can be performed with the `/` operator or `np.divide()`.
```python
# Element-wise division
result = np.divide(a, b) # or a / b
print(result)
# Output: [0.25 0.4 0.5 ]
```
**Exponentiation**:
Raise the elements of one array to the powers of another using `**` or `np.power()`.
```python
# Element-wise exponentiation
result = np.power(a, 2) # or a ** 2
print(result)
# Output: [1 4 9]
```
**Modulus**:
The modulus operation returns the remainder of division using `%` or `np.mod()`.
```python
# Element-wise modulus
result = np.mod(a, b) # or a % b
print(result)
# Output: [1 2 3]
```
**Reciprocal**:
The reciprocal of an array is obtained by taking the inverse of each element. In NumPy, you can compute the reciprocal using the `np.reciprocal()` function or the `1 / array` expression.
```python
import numpy as np
# Define an array
a = np.array([1, 2, 3])
# Element-wise reciprocal
reciprocal_result = np.reciprocal(a) # or 1 / a
print(reciprocal_result)
# Output: [1. 0.5 0.33333333]
```
The reciprocal of each element in the array `a` is computed as follows:
- Reciprocal of 1: 1.0
- Reciprocal of 2: 0.5
- Reciprocal of 3: approximately 0.3333 (rounded to 4 decimal places)
These operations are highly optimized in NumPy and can be performed on arrays of any size, making them very efficient for numerical computations😊. | lohith0512 |
1,858,484 | Top mistakes to avoid when integrating stripe | Integrating Stripe into your application can streamline your payment processes, but it's essential to... | 0 | 2024-05-24T09:44:46 | https://dev.to/softylines/top-mistakes-to-avoid-when-integrating-stripe-be8 | stripe, bestpractises | Integrating Stripe into your application can streamline your payment processes, but it's essential to be aware of potential pitfalls and best practices. Here are some common mistakes and advice to help you navigate the integration smoothly.
## 1. Managing Webhooks Order
**Webhooks** are a way for Stripe to communicate with your system by sending webhook events. However, webhook events do not guarantee order delivery. It’s essential to implement logic in your system to handle the order of events correctly. This prevents potential issues that can arise from processing out-of-order events.
For example, when dealing with **subscriptions**, Stripe might send you the update event before the create event, causing an error since you will try to update something in your system that does not exist yet. To handle this scenario, you can add logic in your **update** event to check for the subscription's existence. If it's not present, retrieve it directly from Stripe, then update it.
## 2. How To Reduce Latency When Working with Stripe's APIs
Latency issues can arise when dealing with Stripe’s APIs. For example, fetching customer **invoices** from Stripe can be a slow operation. To mitigate this, consider storing or caching common data within your system. This approach reduces the need for repeated API calls and improves performance.
## 3. Invoice Links Expire After 30 Days
As you start storing invoices in your database, be aware that the PDF link of the invoice will expire after 30 days. To manage this, you can create a cron job to update the invoices or check the link's validity when retrieving invoices for the user. If the link has expired, get the updated link from Stripe and update it in your database.
[Click for more info in Stripe docs](https://docs.stripe.com/invoicing/hosted-invoice-page#:~:text=Invoice%20URLs%20expire%2030%20days,never%20longer%20than%20120%20days).
## 4. Ensuring You Start with Live Mode In Production
Stripe has two modes: live (production) and test (development).
Sometimes, you might start your production app and begin accepting users even when the app isn't fully finished (especially for startups), thinking you can fix things later. However, when working with Stripe, you cannot switch all your test mode data to live mode (except for a few items). This will be a nightmare for you as a developer when you try to migrate the data. So, you should start your production with live mode from day one.
Bonus: [go-live check list by stripe](https://docs.stripe.com/get-started/checklist/go-live)
## 5. Unsuccessful Payments Due to Account Freshness
Sometimes, payments fail because the account is new, and your website hasn't yet been recognized by payment systems. This issue usually resolves itself over time as your site gains more credibility. Communicate this to your customers to manage their expectations.
## 6. Handling Changes in Payment Methods
Payment networks can change payment method details (card number, expiration year, expiration month) at any time. Since you may store payment methods in your database, it’s crucial to stay updated by listening to the `automatically_updated_payment_method` Stripe webhook. This webhook provides the latest data to keep your records up to date.
## 7. Managing Complex Plan Features
If your plans (offers) include complex features, add custom fields in your database rather than relying heavily on the plan’s metadata, which is limited. Custom fields provide greater flexibility and scalability for your application.
## Conclusion
Integrating Stripe into your application offers a streamlined payment process, but it comes with its own set of challenges. By understanding and addressing these common mistakes, you can ensure a smoother and more efficient integration. With these best practices, you can enhance your application's functionality and provide a better user experience.
Happy coding!

9. SONUÇ
10. SORULAR
11. KAYNAKÇA
## 1.DNS Sunucusu Nedir?
- DNS, tarayıcınıza girdiğiniz etki alanını, bilgisayar tarafından okunabilir bir IP'ye çeviren bir tür telefon rehberidir. Web tarayıcıları, Internet Protokolu (IP) adresleri aracılığıyla etkileşim kurarlar. Açılımı " Domain Name System" olan DNS de alan adlarını IP adreslerine çevirir, böylece tarayıcılar internet kaynaklarına erişebilir.
- İnternete bağlı her cihaz, diğer makinelerin cihazı bulmak için kullandığı IP adresine sahiptir. DNS sunucuları, insanların 182.172.1.1 gibi IP adreslerini veya 2200: cb00: 2088: 1 :: c428: a4b2 gibi daha karmaşık daha alfa nümerik IP adreslerini ezberleme zorunluluğunu ortadan kaldırır.
## 2.DNS Sunucusu Tarihi
- DNS 1980' den bu yana yaygın olarak kullanılır olmuştur. İnternet hiyerarşi alan adı ve İnternet Protokol (IP) adres boşluğu olmak üzere iki ana ad boşluğunu sağlar. DNS sistemi alan adı hiyerarşisi sağlar ve onunla adres boşluğu arasında çeviri servisi sağlar.
## 3.DNS Aramasındaki Adımlar Nelerdir?
**1. Kullanıcı:** web tarayıcısına ana makine adını yazar. Sorgu internete gider. Sorgu DNS özyinelemeli çözümleyici tarafından alınır.
**2. Çözümleyici:** bir DNS root nameserver’ı sorgular.
**3. Root sunucu:** bir TLD DNS sunucusuyla cevap verir.
**4. Çözümleyici:** Daha sonra TLD DNS sunucusuna bir istekte bulunur.
**5. TLD sunucusu daha sonra alan adının:** ad sunucusunun IP adresiyle yanıt verir.
**6. Özyinelemeli çözümleyici:** alan adının ad sunucusuna bir sorgu gönderir.
**7. Ana makine IP adresi:** Ad sunucusundan çözümleyiciye döndürülür.
**8. DNS çözümleyici:** Daha sonra web tarayıcısına başlangıçta talep edilen alan adının IP adresiyle yanıt verir.
- Bu 8 adım ana makinenin IP adresini döndürdüğünde, tarayıcı web sayfası için istekte bulunabilir.
**9. Tarayıcı :** İlgili IP adresine bir HTTP isteği gönderir.
**10. İlgili IP adresindeki sunucu:** Tarayıcıda oluşturulacak web sayfasını döndürür.
## 4. DNS Kayıt Tipleri Nelerdir?
**A:** Host adını IP adresine yönlendiren kayıttır.
**MX:** DNS’e gelen maillerin yönlendirildiği mail sunucunun kayıtlarıdır.
**TXT:** Özel amaçlı kayıtlardır. Genellikle spam karşıtı olarak kullanılır.
**PTR:** IP adresini domain ismine çeviren kayıttır.
**NS:** İsim sunucularının bilgilerinin tutulduğu kayıttır.
**CNAME:** Takma ad kaydıdır. DNS’e ulaşmayı kolaylaştırır.
## 5.DNS İçin Gerekli Dosya Türleri Nelerdir?
DNS’de kullanılan bir kısım dosya türleri vardır. Dosya türleri olmadan DNS’yi çalıştırmanız mümkün değildir. Söz konusu dosya türlerini aşağıda verilmistir.
**boot :** Bu dosya türü, DNS çalışmaya başladığı anda okunan dosyaların ilkidir.
**local :** bu dosya türü, makinenin gösterdiği adresin etkin şekilde çözümlenmesi için kullanılır.
**ca :** Root server olarak adlandırılan adreslerin tutulduğu dosya türü "named.ca"dır.
**hosts :** DNS alanında çalışan tüm makinelerin adreslerinin tutulduğu dosya türü "named.hosts"tur.
**reverse :** "Named.hosts" dosyasında tutulan IP adreslerini makinenin ismine çevirmek için "named.reverse" dosyası kullanılır.
## 6.DNS Nasıl Çalışır?
- DNS, DNS çözümlemesi yaparak ana bilgisayar adını, IP adresine çevirir.
- DNS çözümleme için, DNS sorgusunun farklı donanım bileşenlerinden geçmesi gerekir. Bu noktada kullanıcının tek etkileşimi tarayıcıya domain ismini girip enter tuşuna basmaktır. İşin geri kalan kısmı arka planda gerçekleşir.
- Bir web sitesinin yüklenmesinde 4 adet DNS sunucusu rol oynar:
- **DNS recursor:** DNS recursor, istemcilerden sorgu almak üzere tasarlanan DNS sunucusudur. DNS recursor, bu sorgu alma işlemini web tarayıcısı aracılığıyla gerçekleştirir.
- **Root nameserver:** Domain isminin, IP adresine çevrilmesinde ki ilk adımdır. Daha spesifik konumlara referans olarak hizmet eder.
- **TLD nameserver:** IP aramasında ki bir sonraki adımdır. Ana bilgisayar adının son kısmını barındırır.
- **Authoritative nameserver:** Bu sunucunun istenen kayda erişimi varsa, istenen ana bilgisayar adının IP adresini istemciye geri gönderir. Yani DNS recursor’a geri gönderir.
## 7.DNS Nasıl Değiştirilir?
DNS IP adresleri Default olarak hazır bir şekilde bağlantı ayarlarında yapılandırılmıştır. Bu ayarlar DNS adresi üzerinde değiştirilir?
**Windows Cihazlarda DNS Değiştireme**
- Denetim Masası> Ağ ve İnternet > Ağ Bağlantıları sayfasına gidin.
- İnternet bağlantınıza ait etkin bağlantı aracına sağ tıklayın
- Özellikler’e tıklayın.
- Açılan liste halindeki menüde İnternet Protokolü Sürüm 4’ü seçip Özelliler’e tıklayın.
- Genel Sekmesinde Aşağıdaki DNS sunucu adreslerini kullan kısmına kullanmak istediğiniz DNS sunucusuna ait adresleri girin ve Tamam butonuna basarak çıkış yapın.
- Bilgisayarınızı yeniden başlatarak işlemi tamamlayın
**MacOS dizüstü bilgisayarında Değiştirme**
- Apple menüsünden Tercihleri seçin,
- Ağ uygulamasını başlatın,
- Wi-Fi bağlantısı ve Gelişmiş düğmesine tıklayın,
- DNS sekmesini tıklayın,
- Hem IPv4 hem de IPv6 DNS adreslerini eklemek için artı işareti düğmesini kullanın
- Mevcut adresleri kaldırmak için eksi işareti düğmesini kullanın.
## 8. DNS Sunucuları Ve IP Adresleri?
Bazı DNS sunucuları ve IP adreslerini
## 9. Sonuç
DNS (Domain Name System), tarayıcıya girilen alan adlarını, bilgisayarların anladığı IP adreslerine çeviren bir sistemdir. 1980'lerden beri kullanılan DNS, internetin hiyerarşik alan adı sistemi ile IP adresleri arasında çeviri yapar. DNS araması, kullanıcının tarayıcıya alan adını yazmasıyla başlar ve bu istek sırasıyla DNS çözümleyici, root nameserver, TLD nameserver ve authoritative nameserver üzerinden geçerek, nihayetinde ilgili IP adresine ulaşır ve tarayıcıya iletilir. Önemli DNS kayıt türleri arasında A (host adı-IP adresi), MX (mail yönlendirme), TXT (özel amaçlı), PTR (IP-domain dönüşümü), NS (isim sunucuları) ve CNAME (takma ad) kayıtları bulunur. DNS'in düzgün çalışması için çeşitli dosya türleri (boot, local, ca, hosts, reverse) gereklidir. DNS, bu süreçleri arka planda yürüterek kullanıcıların web sitelerine erişimini sağlar.

##How important is the voice over in a corporate video?
Embark on a journey to understand ‘voiceovers’, where an unseen narrator explains visuals on-screen. Voiceovers add depth and emotion, bringing static visuals to life, simplifying complex information, and creating connections with viewers.

lastName: string;
phoneNumber?: string;
question?: string;
}
const initialValue: IInitialValue = {
email: "",
firstName: "",
lastName: "",
phoneNumber: "",
question: "",
};
const ContactForm = () => {
const resolver = yup.object({
email: yup
.string()
.matches(emailRules, {
message: "E-mail moet een geldig e-mailadres zijn!",
})
.required("Vul alstublieft dit veld in!"),
firstName: yup.string().required("Vul alstublieft dit veld in!"),

}
};
return (
<section className={s._Root}>
<Container className={s._Container}>
<form
className={s._Card}
onSubmit={form.handleSubmit(onSubmit)}
method="post"
>
<Typography component="h2" variant="h2">
Neem contact met ons op
</Typography>
<div className={s._Card__Row}>
<InputField
{...form.register("firstName")}
id="voornaam"
label="Voornam"
helperText={form.formState.errors.firstName?.message}
error={Boolean(form.formState.errors.firstName?.message)}
required
/>

id="achternaam"
label="Achternaam"
helperText={form.formState.errors.lastName?.message}
error={Boolean(form.formState.errors.lastName?.message)}
required
/>
</div>
<div className={s._Card__Row}>
<InputField
{...form.register("phoneNumber")}
id="telefoonnummer"
label="Telefoonnummer"
helperText={form.formState.errors.phoneNumber?.message}
error={Boolean(form.formState.errors.phoneNumber?.message)}
/>
<InputField
{...form.register("email")}
id="e-mail"
label="E-mail"
helperText={form.formState.errors.email?.message}
error={Boolean(form.formState.errors.email?.message)}
required

>
{form.formState.isSubmitting ? "Bezig met laden..." : "Verzend"}
</Button>
</form>
</Container>
</section>
);
};
export default ContactForm;
```
## Let's breakdown part by part
### 1. setup the initial value with the type or interface
define the default value of the form that you will create
```tsx
...
interface IInitialValue {
email: string;
firstName: string;
lastName: string;
phoneNumber?: string;
question?: string;
}
const initialValue: IInitialValue = {
email: "",
firstName: "",
lastName: "",
phoneNumber: "",
question: "",
};
...
```
### 2. setup the handle form with useForm
```tsx
const form = useForm({
defaultValues: initialValue,
resolver: yupResolver(resolver),
});
```
### 3. write the resolver or validation
```tsx
...
const resolver = yup.object({
email: yup
.string()
.matches(emailRules, {
message: "E-mail moet een geldig e-mailadres zijn!",
})
.required("Vul alstublieft dit veld in!"),
firstName: yup.string().required("Vul alstublieft dit veld in!"),
lastName: yup.string().required("Vul alstublieft dit veld in"),
phoneNumber: yup
.string()
.test(
"matches-phone",
"Het mobiele telefoonnummer moet een geldig mobiel nummer zijn!",
(value) => {
if (!value) return true;
return phoneNumberRules.test(value);
}
),
question: yup.string(),
});
...
```
- email field use the custom rules for email, in this case I use the regex from `emailRules`
- firstName & lastName field is required
- question is not required and only allow string value
- phoneNumber is not required but the value should the correct phoneNumber in this case I use regex to handle the rules
### 4. register each field to useForm
I register each field like below. I not only register, I also put the error state and error message when the value not match with the rules. and make the field disabled when the form submiting
```tsx
...
<InputField
{...form.register("firstName")}
id="voornaam"
label="Voornam"
helperText={form.formState.errors.firstName?.message}
error={Boolean(form.formState.errors.firstName?.message)}
disabled={form.formState.isSubmitting}
required
/>
...
```
### 5. Handle submit
```tsx
...
const onSubmit = async (data: typeof initialValue) => {
try {
await submitFormService({
data: data,
});
form.reset();
notifySuccess("Het contact is succesvol verzonden!");
} catch (error) {
handleError(error);
}
};
...
<form className={s._Card} onSubmit={form.handleSubmit(onSubmit)} method="post">
...
</form>;
...
```
### 6. Add state to Button
Add state text if necessary, and make the button disabled while submitting
```tsx
...
<Button component="button" type="submit" disabled={form.formState.isSubmitting}>
{form.formState.isSubmitting ? "Bezig met laden..." : "Verzend"}
</Button>
...
```

1,863,773 | What's New in API7 Enterprise 3.2.12: Supporting Stream Routes | In API7 Enterprise 3.2.12, support for stream routes has been introduced, enabling TCP/UDP protocol... | 0 | 2024-05-24T09:33:09 | https://api7.ai/blog/api7-3.2.12-stream-routes | In [API7 Enterprise](https://api7.ai/enterprise) 3.2.12, support for stream routes has been introduced, enabling TCP/UDP protocol traffic proxy and load balancing.
By configuring stream routes, API7 Enterprise can proxy requests for services such as MySQL and MongoDB based on the TCP protocol. It can also proxy applications like Redis that can be configured with either TCP or UDP protocols. This enables effective management and optimization of TCP/UDP network traffic.
## How to Use Stream Routes in API7 Enterprise?
### Adding Stream Service
When manually adding a service, an option for service type selection has been added, supporting two types: HTTP and Stream, representing Layer 7 proxy and Layer 4 proxy, respectively. If the service type is selected as `Stream`, the upstream schema can be chosen as either `TCP` or `UDP`. It is important to note that once the service type is selected, it can not be changed, so ensure the correct service type is chosen.
### Adding Stream Routes
After successfully creating a Stream-type service, it will be directed to the service details page. The next step is to add routes by clicking the `Add Stream Route` button.
Fill in the route name, description, and relevant route configuration in the form. Here, we configure a route for proxying MySQL service.
Compared to regular HTTP route configurations, stream routes has three different configuration options.
- **Server Address**: This is the address where the gateway server receives stream route connections, serving as the entrance for stream route traffic into the gateway. When clients seek to establish connections, they send requests to this address, and the gateway forwards or handles these requests based on the predefined routing rules.
- **Server Port**: It is used to specify the port on which the gateway server listens for traffic.
- **Remote Address**: It is the client address that initiates the request. Only requests sent from client addresses that are the same as the remote address can be forwarded, thus enabling traffic management for specific clients.
After successfully creating the route, we can see the newly added MySQL route in the list.
### Configuring Upstream Nodes and Publishing the Service
Next, we will publish the service to the gateway group and add an upstream node corresponding to the MySQL service.
After the service is published, when the gateway server at `127.0.0.10` and port `9101` receives a request, this route will be responsible for handling the request and forwarding it to the upstream MySQL service.
In addition to the basic request forwarding feature, after service publication, the performance and security of the service can be enhanced through a series of configurations. For example, load balancing strategies can be configured for stream routes to ensure traffic is evenly distributed among multiple upstream MySQL servers, thereby improving system scalability and fault tolerance.
Furthermore, [health check](https://api7.ai/blog/api7-3.2.9-upgraded-health-check-configuration) mechanisms can be set up to periodically monitor the status of upstream servers, ensuring only healthy servers receive and forward requests, and avoiding service interruptions due to server failures.
### Supported Plugins
Currently, there are four plugins supported for stream routes:
1. [`ip-restriction`](https://docs.api7.ai/hub/ip-restriction/): Provides IP access control capabilities.
2. [`limit-conn`](https://apisix.apache.org/docs/apisix/3.3/plugins/limit-conn/): This plugin can restrict the number of concurrent requests from clients to a single service.
3. [`prometheus`](https://docs.api7.ai/hub/prometheus): Provides system monitoring and alerting capabilities for stream routes.
4. [`syslog`](https://docs.api7.ai/hub/syslog): Records and sends system logs.
These four plugins collectively enhance the security, stability, monitoring, and maintainability of stream routes.
## Conclusion
The stream routes feature in API7 Enterprise 3.2.12 provides users with more robust and flexible TCP/UDP protocol traffic management, contributing to improved application reliability and scalability. It brings enhanced network traffic management, higher system reliability and operational efficiency, and superior business adaptability for enterprise users, making it valuable for supporting the operation of critical enterprise applications. | yilialinn | |

DistilBERT is a revolutionary language model that aims to make large-scale language processing more efficient and cost-effective. Developed by Hugging Face, DistilBERT is a distilled version of BERT, a widely used language model that has significantly improved the state-of-the-art in NLP tasks.
Language models like BERT have been growing in size and complexity, with models like Nvidia’s latest release having 8.3 billion parameters, 24 times larger than BERT-large. While these larger models have led to better performance, they come with environmental and financial costs.
## Understanding the Need for Compact Models
Smaller models like DistilBERT also have practical advantages. They can be deployed on resource-constrained devices like smartphones without compromising performance. This enables the development of real-world applications that can run on-device, reducing the need for costly GPU servers and ensuring data privacy.
The smaller size of DistilBERT also results in faster inference times on CPU, making it ideal for applications that require low latency and responsiveness, such as chatbots or voice assistants. This is especially important in the field of machine learning, where compact models like DistilBERT are becoming increasingly necessary for efficient and effective on-device processing.
## What is DistilBERT
DistilBERT is a distilled version of BERT, the original transformer-based language model that has revolutionized NLP. While BERT has achieved remarkable performance on various NLP tasks, its large size and computational requirements make it challenging to use in resource-constrained settings.
**Core Concepts Behind DistilBERT**
The core concepts behind DistilBERT are knowledge distillation, inductive biases, and the transformer architecture. Knowledge distillation is the technique used to compress a larger model, like BERT, into a smaller model, like DistilBERT. It involves training the smaller model to mimic the behavior of the larger model.
Inductive biases refer to the assumptions or prior knowledge embedded in the architecture and training process of a model. DistilBERT benefits from the inductive biases learned by BERT during pre-training, allowing it to generalize well to various NLP tasks.
The transformer architecture, originally introduced by Vaswani et al., forms the basis of both BERT and DistilBERT. It consists of self-attention mechanisms that capture the context and relationships between words in a sentence, enabling the models to understand and generate natural language.
## The Mechanism of Distilling Knowledge in DistilBERT
The mechanism of distilling knowledge in DistilBERT involves training the student model to mimic the output distribution of the teacher model. During training, the student model learns to produce similar probabilities for each class as the teacher model.
The distillation process consists of minimizing the difference between the logits (output scores before applying softmax) of the student and teacher models. The student model is trained to predict the same high probabilities for the correct classes as the teacher model.
By incorporating the knowledge from the teacher model, the student model is able to approximate the behavior of the larger model and achieve similar performance on downstream tasks. This distillation process allows for the compression of the knowledge learned by the teacher model into a smaller and more efficient model like DistilBERT.
**Technical Specifications of DistilBERT**
DistilBERT has several technical specifications that make it a more compact and efficient model compared to BERT. It has approximately 40% fewer parameters than BERT, making it lighter and more suitable for on-device computations.
In terms of inference, DistilBERT is significantly faster than BERT, with a 60% reduction in inference time. This allows for more efficient processing of text data and enables real-time applications.
DistilBERT achieves these improvements in efficiency and speed by leveraging knowledge distillation and incorporating inductive biases learned by the larger model. These technical specifications make DistilBERT a valuable tool for NLP tasks that require fast and efficient language processing.
## DistilBERT vs. BERT: A Comparative Analysis
A comparative analysis between DistilBERT and BERT reveals key differences in performance, model size, and training time. While DistilBERT is a compressed version of BERT, it retains 97% of BERT’s performance on various NLP tasks.
DistilBERT’s smaller model size makes it more efficient in terms of memory usage and storage requirements. This enables faster training and inference times compared to BERT.
Despite the reduction in model size, DistilBERT maintains high performance on a wide range of NLP tasks, making it a suitable alternative for applications with limited resources or stricter computational constraints.
## Performance Metrics: DistilBERT’s Efficiency and Accuracy
DistilBERT’s performance can be evaluated based on its efficiency and accuracy across various downstream tasks. When compared to BERT, DistilBERT demonstrates comparable or even better performance while being a more efficient and lightweight model.
DistilBERT performs well on the General Language Understanding Evaluation (GLUE) benchmark, which consists of multiple downstream NLP tasks. It achieves high accuracy and F1 scores on tasks such as sentiment analysis, text classification, and question answering.
The efficiency of DistilBERT is reflected in its smaller model size and faster inference times. This makes it more suitable for real-time applications, where low latency and responsiveness are crucial. Additionally, DistilBERT’s reduced computational requirements contribute to a lower environmental impact, making it a more sustainable choice for NLP tasks.
## How to Implement DistilBERT
Huggingface’s Transformers library provides a range of DistilBERT models in various versions and sizes. In this guide, we will demonstrate how to load a model and perform single-label classification.
First, we will install and import the necessary packages. Then, we will load the “distilbert-base-uncased-finetuned-sst-2-english” model along with its tokenizer using DistilBertForSequenceClassification and DistilBertTokenizer, respectively. Next, we will tokenize the input data, and use the tokenized output to predict the label, which in this example, is sentiment analysis.
!pip install -q transformers
import torch
from transformers import DistilBertTokenizer, DistilBertForSequenceClassification
tokenizer = DistilBertTokenizer.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english")
model = DistilBertForSequenceClassification.from_pretrained("distilbert-base-uncased-finetuned-sst-2-english")
inputs = tokenizer("Wow! What a surprise!", return_tensors="pt")
with torch.inference_mode():
logits = model(**inputs).logits
predicted_class_id = logits.argmax().item()
model.config.id2label[predicted_class_id]
## DistilBERT in Action: Case Studies
DistilBERT has been successfully applied in various case studies, demonstrating its effectiveness in different NLP tasks. Two noteworthy examples are sentiment analysis and text classification.
**Enhancing Text Classification with DistilBERT**
DistilBERT can greatly enhance text classification tasks by providing accurate predictions in a faster and more efficient manner. It uses the same architecture as BERT but with fewer layers and removed token-type embeddings and pooler.
Despite these changes, DistilBERT retains 95% of BERT’s performance on the GLUE benchmark for language understanding. This makes DistilBERT a powerful tool for various text classification tasks, including sentiment analysis, named entity recognition, and intent detection.
**Leveraging DistilBERT for Sentiment Analysis**
Sentiment analysis is a common NLP task that involves determining the sentiment or emotion expressed in a piece of text. DistilBERT, specifically the DistilBertForSequenceClassification model, is well-suited for sentiment analysis as it has been trained on a large corpus of text and has a strong understanding of language. By fine-tuning DistilBERT on a sentiment analysis dataset, it can accurately classify text into positive, negative, or neutral sentiments.
The probabilities assigned to each sentiment class by DistilBERT can be used to gauge the strength of the sentiment expressed in the text. With its smaller size and faster inference time, DistilBERT is an ideal choice for sentiment analysis applications that require real-time analysis of large amounts of text, such as social media monitoring or customer feedback analysis.
## Advanced Tips for Maximizing DistilBERT’s Capabilities
**Optimizing DistilBERT for Speed and Memory Usage**
To maximize the speed and memory usage of DistilBERT, it is recommended to utilize GPU acceleration and optimize the code for parallel processing. This can significantly reduce the inference time of DistilBERT, making it more efficient for real-time applications. Additionally, using techniques such as quantization and pruning can further reduce the memory usage of DistilBERT without compromising its performance.
Best Practices for Training DistilBERT on Custom Datasets
When training DistilBERT on custom datasets, it is important to follow best practices to achieve optimal results. This includes properly preprocessing the data, ensuring a balanced distribution of classes, and fine-tuning the model with an appropriate learning rate and number of epochs. Data augmentation techniques, such as random word masking or shuffling, can also be applied to increase the diversity of the training data and improve the model’s generalization capabilities.
**Optimizing DistilBERT for Speed and Memory Usage**
To optimize DistilBERT for speed and memory usage, there are several techniques that can be applied.
First, utilizing hardware acceleration such as GPUs can greatly improve the inference speed of DistilBERT.
Additionally, optimizing the code for parallel processing and leveraging batch processing, such as training on very large batches, can further enhance the speed of DistilBERT’s computations. To reduce memory usage, techniques such as quantization (approximating the weights of a network with a smaller precision) and weights pruning (removing some connections in the network) can be used.
## The Future of Compact Models Like DistilBERT
Compact models like DistilBERT represent the future of NLP as they offer a more efficient and cost-effective solution compared to larger models. The demand for on-device language processing capabilities is increasing, and compact models provide a viable solution that can run on resource-constrained devices.

1,860,139 | How we saved our partners 💵$460,000 and 2,5 months⏰ of work | In 2022, I worked on a data science project for a retailer. The project was to predict cashflows... | 0 | 2024-05-24T09:16:35 | https://dev.to/taipy/how-we-saved-our-partners-460000-and-25-months-of-work-40kg | opensource, startup, datascience, ai | In 2022, I worked on a data science project for a retailer. The project was to predict cashflows through better demand forecasting and inventory management. This project followed the common pitfalls of all data science and AI projects and made me rethink our strategy and tools.
I’ll tell you all about the mistakes I made ( and will never do again) and what tool I used to save money and time.
<hr/>
## Common pitfalls in AI & Data projects
Over the years, I’ve worked on many AI and dastascience projects, delivering substantial ROI through algorithms and AI models. Despite the AI hype, many non-software companies struggle with successful AI strategies, often limited to standard data projects and few impactful AI deployments, resulting in uneven AI adoption.
<hr/>
### Here are the main causes:
- **Siloed Teams**: There’s often a big disconnect between the data scientists and the end-users. There are valid reasons for having different roles and the need for specialization.
However, it's important to recognize that in real projects, this leads to a significant gap between data scientists and end-users. Each group tends to use different technology stacks; for instance, data scientists usually work with Python, while IT developers might use JavaScript, Java, Scala, and other languages.
This influences teamwork in taking more time and making teamwork tricky.
These are the various groups involved in a typical AI/ DS project:
- **Getting acceptance from the end-users / business users:** If end-users aren't part of the development process, they might not use the software once it’s up and running.
<hr/>
## What I needed:
1- **Go All-In on Python**: It's easy to learn and works well with other tech. It is at the heart of the AI stack and ideal for integrating with other environments. We considered libraries like Streamlit, which is excellent for prototype quick applications, but we quickly felt the limits of this library for performant multi-user applications.
2- **Better Interaction with end-users**: It is critical to ensure the software works well for users and track how happy they are with it.
<hr/>
## The solution:
Taipy came from the need for a easy tool, like Python, and strong enough for big projects. It handles loads of data fast, can be tailored to specific business needs, and connects data scientists with business users. It also makes decision-making smarter with features that let users play with different scenarios.
Now let's go into detail:
### - Answer to the siloed teams
The obvious answers would go towards these points:
1. Standardize on a single programming language.
2. Provide an easy-to-learn and use programming experience for all skill levels.
3. Python is ideal for AI, with many user-friendly libraries, though they often face performance and customization issues.
For instance, libraries like Plotly Dash offer full-code solutions, while Streamlit or Gradio are easier but lack performance and flexibility. Python developers shouldn't have to choose between productivity and performance.
We created Taipy to combine ease of development with high performance and customization.
<hr/>
### - Answer to bringing back the end-user to the center of the project
Addressing the two key points is crucial:
1. Smooth end-user interaction with backend algorithms.
For smooth interaction, end-users need control over algorithm variables through the GUI, the ability to run algorithms with different parameters, and the option to compare results and track KPI performance over time. Taipy addresses this with the 'scenario' concept, storing all data elements and enabling users to track runs, revisit past scenarios, and analyze results.
2. Easy tracking of business-user satisfaction.
For tracking satisfaction, Taipy's scenario function bridges the gap between end-users and data scientists by providing access to all runs and allowing end-users to tag and share scenarios with data scientists. This feature enhances software acceptance beyond basic testing and drift detection.
<hr/>
### Taipy - Build Python Data & AI web applications
Support open-source and give Taipy a star: https://github.com/Avaiga/taipy
<hr/>
## What about the results?
Implementing Taipy transformed our approach to managing cash flow and demand forecasting. The tool improved our processing capabilities by leaps and bounds and gained quick acceptance from end-users thanks to its intuitive design and relevance to their daily tasks.
We went from using 4 full-time developers to 1.5. The initial team was eclectic, with specialties ranging from Javascript and Java and Python.
The use of Taipy enabled the data scientist using Python to create a full-blown application ready for use by the end-users. This facilitated communication and reduced the siloed team process common to all AI projects. A gain of time and money is crucial to the success of any project.
For the concrete results, Taipy reduced the overall costs by a factor 10!
| Project Phase | Budget | IT Staff | Duration |
| --- | --- | --- | --- |
| Initial Setup | $600K | 4 | 8 months |
| With Taipy | $60K | 1.5 | 2 months |
<hr/>
## Achievements:
**4x Faster Projects**: We sped up everything from start to finish and spent less on keeping things running.
**10x Cheaper**: Most of the tech work was done by Python developers, reducing the need for help from other departments and making project management a breeze.
Check out these applications made with Taipy: https://docs.taipy.io/en/latest/gallery/
## Conclusion

1,863,762 | Simplifying Nested Routes in React Router | Introduction React Router v6 introduces a powerful and flexible way to manage routing in... | 0 | 2024-05-24T09:12:00 | https://dev.to/vikram-boominathan/simplifying-nested-routes-in-react-router-4ip | react, webdev, beginners, javascript | ## Introduction
React Router v6 introduces a powerful and flexible way to manage routing in React applications. With features like nested routes, index routes, relative paths, NavLink, and Outlet components, it offers a seamless navigation experience. In this guide, we'll walk through setting up a React application with nested routes and explore these features in detail.
### Key Concepts
**1. Index Route**
An index route is the default child route that renders when the parent route is matched but no other child routes are matched. It's typically used to display a default view or landing page for a section of your application.
In **`App.js`**, the index prop on a **<Route>** inside dashboard makes Profile the default component for /dashboard.
```react
<Route path="dashboard" element={<Dashboard />}>
<Route index element={<Profile />} />
<Route path="settings" element={<Settings />} />
</Route>
```
**2. Nested Routes**
In React, nested routes simply refer to a routing structure in which routes are included in other routes, resulting in a tree of routes. This concept is critical for developing applications with complex navigational structures because it allows you to create menus with multiple levels or sub-pages that can relate to the main page.
In simple terms, **UI sharing** between pages is easier.
```react
<Routes>
<Route path="/" element={<Layout />}>
<Route index element={<Home />} />
<Route path="dashboard" element={<Dashboard />}>
<Route index element={<Profile />} />
<Route path="settings" element={<Settings />} />
</Route>
</Route>
</Routes>
```
**3. NavLink**
NavLink is a React component which allows us to navigate within a React application. It is similar to the Link component, but with additional features that make it ideal for creating navigational links with **active styling**.
When you use the **end** prop, NavLink is only considered active if the route matches the URL exactly. Without the end prop, NavLink can be active on any sub-path.
```react
<NavLink to="/" end style={({ isActive }) => ({ color: isActive ? 'red' : 'black' })}>
Home
</NavLink>
<NavLink to="dashboard" style={({ isActive }) => ({ color: isActive ? 'red' : 'black' })}>
Dashboard
</NavLink>
```
**4. Outlet and Context**
**Outlet** is a placeholder component for nested routes. It serves as a method for rendering child components or routes within a parent component.
**Context** can be passed down the route tree.This enables you to share data and functionality between route components.
The Outlet component renders the matched nested route. Outlet context is provided to share data between parent and child routes.
```react
<Outlet context={{ user }} />
```
**5. useOutletContext**
The library provides a hook called **useContextOutlet** that lets you access the closest **<Outlet>** component in your component hierarchy. When you need to access the outlet's context, this can be helpful.
```react
import { useOutletContext } from 'react-router-dom';
const Profile = () => {
const { user } = useOutletContext();
../
<p>Name: {user}</p>
../
```
**6. Relative Paths**
In Dashboard, Link to="" navigates to the Profile component which is a index route and Link to="settings" navigates to the Settings component.
```react
<Link to="">Profile</Link>
<Link to="settings">Settings</Link>
```
### Getting Started
First, create a new React application using create-react-app and install react-router-dom.
```bash
npx create-react-app react-router-example
cd react-router-example
npm install react-router-dom
```
### Setting Up Routes
In **`App.js`**, we'll define our routes using the Routes and Route components. We'll also create nested routes for the dashboard.
```react
import React from 'react';
import { Routes, Route, BrowserRouter } from 'react-router-dom';
import Layout from './components/Layout';
import Home from './components/Home';
import Dashboard from './components/Dashboard';
import Profile from './components/Profile';
import Settings from './components/Settings';
function App() {
return (
<BrowserRouter>
<Routes>
<Route path="/" element={<Layout />}>
<Route index element={<Home />} />
<Route path="dashboard" element={<Dashboard />}>
<Route index element={<Profile />} />
<Route path="settings" element={<Settings />} />
</Route>
</Route>
</Routes>
</BrowserRouter>
);
}
export default App;
```
#### Creating the Layout Component
The Layout component includes navigation links and an Outlet for nested routes.
```react
import React from 'react';
import { NavLink, Outlet } from 'react-router-dom';
const Layout = () => {
return (
<div>
<nav>
<ul>
<li>
<NavLink to="/" end style={({ isActive }) => ({ color: isActive ? 'red' : 'black' })}>
Home
</NavLink>
</li>
<li>
<NavLink to="dashboard" style={({ isActive }) => ({ color: isActive ? 'red' : 'black' })}>
Dashboard
</NavLink>
</li>
</ul>
</nav>
<hr />
<Outlet />
</div>
);
};
export default Layout;
```
#### Home Component
The Home component is a simple functional component.
```react
import React from 'react';
const Home = () => {
return (
<div>
<h2>Home</h2>
<p>Welcome to the home page!</p>
</div>
);
};
export default Home;
```
#### Dashboard Component with Nested Routes
The Dashboard component includes links for its **nested routes** and an **Outlet** for rendering them.
```react
import React from 'react';
import { Link, Outlet } from 'react-router-dom';
const Dashboard = () => {
const user = { name: 'John Doe', role: 'Admin' }; // Example user data
return (
<div>
<h2>Dashboard</h2>
<nav>
<ul>
<li>
<Link to="">Profile</Link>
</li>
<li>
<Link to="settings">Settings</Link>
</li>
</ul>
</nav>
<hr />
<Outlet context={{ user }} />
</div>
);
};
export default Dashboard;
```
#### Profile Component
The Profile component retrieves context data using **useOutletContext**.
```react
import React from 'react';
import { useOutletContext } from 'react-router-dom';
const Profile = () => {
const { user } = useOutletContext();
return (
<div>
<h3>Profile</h3>
<p>Name: {user.name}</p>
<p>Role: {user.role}</p>
</div>
);
};
export default Profile;
```
#### Settings Component
The Settings component also uses **useOutletContext** to access user data.
```react
import React from 'react';
import { useOutletContext } from 'react-router-dom';
const Settings = () => {
const { user } = useOutletContext();
return (
<div>
<h3>Settings</h3>
<p>Adjust your settings here, {user.name}.</p>
</div>
);
};
export default Settings;
```

Ouch! If you showed that to your friends while claiming you're a web developer, they would start questioning what you're really doing...
Default browser stylesheets are usually pretty bare-bones, and it can be frustrating to not have something "visually nice" when you're prototyping apps, generating static HTML pages, Markdown-generated documents, etc., and don't want to delve into CSS intricacies too early.
Good news! I have something perfect for you: [matcha.css](https://matcha.mizu.sh)!
Just add the following into your document and see the magic happen:
```html
<link rel="stylesheet" href="https://matcha.mizu.sh/matcha.css">
```
Without really doing anything, we got a page that respects user preferences on light/dark mode, nice fonts and proper spacing, our `<menu>` actually looks like a menu, and our `<form>` is also pretty nice with even "mandatory field" indicators for required inputs.
All of that without any build steps, JavaScript, configuration, or refactoring.
It's because [matcha.css](https://matcha.mizu.sh) uses semantic styling. For example, it assumes that `<menu>` nested in another `<menu>` should result in a submenu, while a `<label><input required></label>` should clarify to the user that the input is mandatory.
There are a few more "drop-in" CSS libraries out there, but I believe this is the most complete one as it provides additional modern styles out-of-the-box like syntax highlighting, simple layouts, utility classes, etc.
[matcha.css](https://matcha.mizu.sh) is also easily customizable (it does not have any `!important` rules, and even provide a helper to create custom builds) and while being also reversible (if you ever decide to migrate out, just remove the stylesheet).
And last but not least, it's totally free and open-source!

With the rapidly changing and... | 0 | 2024-05-24T09:06:53 | https://dev.to/fmzquant/how-to-measure-position-risk-an-introduction-to-the-var-method-3pgp | position, trading, cryptocurrency, fmzquant | Controlling risk is a skill that every investor needs to learn. With the rapidly changing and evolving cryptocurrency market, algorithmic traders need to focus on risk management especially. This is because algorithmic trading often executes trades automatically based on historical data and statistical models, which may quickly become inaccurate in fast-moving markets. Therefore, effective risk management strategies are crucial for protecting investors' capital.
Among many risk management tools, Value at Risk (VaR) is a widely used measure of risk. It can help investors predict the maximum loss that might occur under normal market conditions in their portfolio. VaR quantifies risk into a single number, simplifying the expression of risk and allowing investors to understand potential losses intuitively.
### The Role of VaR
VaR, or "Value at Risk", is used to quantify the maximum possible loss that can be endured within a certain period of time, according to a certain confidence level. In other words, it tells investors or risk managers: "Under normal market conditions, how much money is within the 'safe' range and will not be lost tomorrow." For example, if the 1-day 99% VaR of a cryptocurrency portfolio is $10,000, it means that in 99% of cases we expect the loss in one day will not exceed $10,000.
### Advantages
1. **Easy to understand** : For example, the 1-day 95% VaR of a digital currency portfolio is $5000, which means there is a 95% confidence that the loss of the portfolio within one day will not exceed $5000. Quantifying complex risks into an intuitive number makes it easy for non-professionals to understand. Of course, it's inevitably to have some misleading aspects.
2. **Relatively standard** : Suppose there are two portfolios A and B, with A's 1-day 95% VaR being $3000 and B's being $6000. This implies that under normal market conditions, A's risk is lower than B's. Even if these two portfolios contain different assets, we can compare their risk levels directly. Correspondingly, we can also judge the level of investment; if both strategies A and B have earned $6000 in the past month but A's average and maximum VaR values are significantly lower than B's, then we could consider strategy A as better, since it achieves higher returns at a lower risk level.
3. **Decision-making tool** : Traders might use VaR to decide whether or not to add a new asset to their portfolio. If adding an asset increases the VaR value significantly, then it may suggest that the added asset's risk does not match with the portfolio's acceptable risk level.
### Disadvantages
1. **Ignoring tail risk** : If a portfolio's 1-day 99% VaR is $10,000, the loss in the extreme 1% scenario could far exceed this value. In the field of digital currency, black swan events are frequent and extreme situations can exceed most people's expectations, because VaR does not consider tail events.
2. **Assumption limitations** : The parameter VaR often assumes that asset returns are normally distributed, which is rarely the case in real markets, especially in digital currency markets. For example, suppose a portfolio only contains Bitcoin. We use the parameter VaR and assume that Bitcoin's return is normally distributed. However, in reality, Bitcoin's rate of return may experience large jumps during certain periods and exhibit significant volatility clustering phenomena. If there has been high volatility over the past week, the probability of noticeable volatility in the following period will increase significantly. This can lead to an underestimation of risk by normal distribution models. Some models take this issue into account such as GARCH etc., but we won't discuss them here.
3. **Historical dependence** : The VaR model relies on historical data to predict future risks. However, past performance does not always indicate future situations, especially in rapidly changing markets like the digital currency market. For example, if Bitcoin has been very stable over the past year, a historical simulation might predict a very low VaR. However, if there is a sudden regulatory change or market crash, past data will no longer be an effective predictor of future risk.
### Methods of Calculating VaR
There are mainly three methods to calculate VaR: Parametric method (Variance-Covariance Method): This assumes that the rate of return follows a certain distribution (usually normal distribution), and we use the mean and standard deviation of the rate of return to calculate VaR. Historical Simulation Method: It makes no assumptions about the distribution of returns, but uses historical data directly to determine potential loss distributions. Monte Carlo Simulation: It uses randomly generated price paths to simulate asset prices and calculates VaR from them.
The Historical Simulation Method utilizes past price changes directly to estimate possible future losses. It does not need any assumptions about profit distribution, making it suitable for assets with unknown or abnormal profit distributions, such as digital currencies.
For example, if we want to calculate 1-day 95% VaR for a Bitcoin spot position, we can do this:
1. Collect the daily returns of Bitcoin over a certain period (for example, 100 days).
2. Calculate the portfolio return rate each day, which is the return rate of each asset multiplied by its weight in the portfolio.
3. Sort these 100 days of portfolio returns from low to high.
4. Find the data point at the 5% mark (because we are calculating 95% VaR). The point represents the loss rate on the best day out of worst five days in past 100 days.
5. Multiply the return by total value held, and that's your one-day 95% VaR.
The following is a specific code that has obtained data from the past 1000 days, calculating that the current VaR for holding one BTC spot is 1980 USDT.
```
import numpy as np
import requests
url = 'https://api.binance.com/api/v3/klines?symbol=%s&interval=%s&limit=1000'%('BTCUSDT','1d')
res = requests.get(url)
data = res.json()
confidence_level = 0.95
closing_prices = [float(day[4]) for day in data]
log_returns = np.diff(np.log(closing_prices))
VaR = np.percentile(log_returns, (1 - confidence_level) * 100)
money_at_risk = VaR * closing_prices[-1] * 1
print(f"VaR at {confidence_level*100}% confidence level is {money_at_risk}")
```
### Calculating VaR Considering Correlation
When calculating the VaR of a portfolio containing multiple assets, we must consider the correlation between these assets. If there is a positive correlation in price changes between assets, then the risk of the portfolio will increase; if it's negatively correlated, then the risk of the portfolio will decrease.
When using historical simulation method to calculate VaR considering correlation, we need to collect not only each individual asset's historical returns, but also consider their joint distribution. In practice, you can use the historical returns of your portfolio for sorting and calculation directly, because these returns already implicitly include inter-asset correlations. In cryptocurrency markets, correlation is especially important with BTC essentially leading market trends. If BTC rises bullishly, other cryptocurrencies are likely to rise as well; if BTC rapidly surges or plummets due to quickly changing market, this could cause significant short-term increases in correlation - something that is particularly common during extreme market events. Therefore, historical simulation method is a useful tool when considering digital currency investment portfolios' VaR calculations. It doesn't require complex statistical models - just effective historical data - and naturally includes inter-asset correlations.
For example: holding 1 long position on BTC and 10 short positions on ETH – following our previous method – we can calculate that 10 ETH short positions have a VaR of 1219 USDT. When combining these two types of assets into one portfolio, here's how you would calculate its combined VaR:
```
confidence_level = 0.95
btc_closing_prices = np.array([float(day[4]) for day in btc_data])
eth_closing_prices = np.array([float(day[4]) for day in eth_data])
btc_log_returns = np.diff(np.log(btc_closing_prices))
eth_log_returns = np.diff(np.log(eth_closing_prices))
log_returns = (1*btc_log_returns*btc_closing_prices[1:] - 10*eth_log_returns*eth_closing_prices[1:])/(1*btc_closing_prices[1:] + 10*eth_closing_prices[1:])
VaR = np.percentile(log_returns, (1 - confidence_level) * 100)
money_at_risk = VaR * (btc_closing_prices[-1] * 1 + eth_closing_prices[-1]*10)
print(f"VaR at {confidence_level*100}% confidence level is {money_at_risk}")
```
The result is 970 USDT, which means the risk of this combination is lower than holding the respective assets separately. This is because BTC and ETH markets have a high correlation, and the hedging effect of long-short position combinations serves to reduce risk.
### Summary
This article will introduce a highly adaptive risk assessment method, namely the application of Historical Simulation in calculating VaR, as well as how to consider asset correlations to optimize risk prediction. Through specific examples from the digital currency market, it explains how to use historical simulation to assess portfolio risks and discusses methods for calculating VaR when asset correlations are significant. With this method, algorithmic traders can not only estimate their maximum loss in most situations, but also be prepared for extreme market conditions. This allows them to trade more calmly and execute strategies accurately.

We'll... | 0 | 2024-05-24T08:58:09 | https://www.shuttle.rs/blog/2024/05/23/building-agentic-rag-rust-qdrant | ai, webdev, rust, tutorial | Hey there! In this article, we're gonna talk about building an agentic RAG workflow with Rust! We'll be building an agent that can take a CSV file, parse it and embed it into Qdrant, as well as retrieving the relevant embeddings from Qdrant to answer questions from users about the contents of the CSV file.
Interested in deploying or just want to see what the final code looks like? You can find the repository [here.](https://github.com/joshua-mo-143/shuttle-agentic-rag)
## What is Agentic RAG?
Agentic RAG, or Agentic Retrieval Augmented Generation, is the concept of mixing AI agents with RAG to be able to produce a workflow that is even better at being tailored to a specific use case than an agent workflow normally would be.
Essentially, the difference between this workflow and a regular agent workflow would be that each agent can individually access embeddings from a vector database to be able to retrieve contextually relevant data - resulting in more accurate answers across the board in an AI agent workflow!
## Getting Started
To get started, use `cargo shuttle init` to create a new project.
Next, we'll add the dependencies we need using a shell snippet:
```bash
cargo add anyhow
cargo add async-openai
cargo add qdrant-client
cargo add serde -F derive
cargo add serde-json
cargo add shuttle-qdrant
cargo add uuid -F v4
```
We'll also need to make sure to have a Qdrant URL and an API key, as well as an OpenAI API key. Shuttle uses environment variables via a `SecretStore` macro in the main function, and can be stored in the `Secrets.toml` file:
```toml
OPENAI_API_KEY = ""
```
Next, we'll update our main function to have our Qdrant macro and our secrets macro. We'll iterate through each secret and set it as an environment variable - this allows us to use our secrets globally, without having to reference the `SecretStore` variable at all:
```rust
#[shuttle_runtime::main]
async fn main(
#[shuttle_qdrant::Qdrant] qdrant_client: QdrantClient,
#[shuttle_runtime::Secrets] secrets: SecretStore,
) -> shuttle_axum::ShuttleAxum {
secrets.into_iter().for_each(|x| {
set_var(x.0, x.1);
});
let router = Router::new()
.route("/", get(hello_world));
Ok(router.into())
}
```
## Building an agentic RAG workflow
### Setting up our agent
The agent itself is quite simple: it holds an OpenAI client, as well as a Qdrant client to be able to search for relevant document embeddings. Other fields can also be added here, depending on what capabilities your agent requires.
```rust
use async_openai::{config::OpenAIConfig, Client as OpenAIClient};
use qdrant_client::prelude::QdrantClient;
pub struct MyAgent {
openai_client: OpenAIClient<OpenAIConfig>,
qdrant_client: QdrantClient,
}
```
Next we'll want to create a helper method for creating the agent, as well as a system message which we'll feed into the model prompt later.
```rust
static SYSTEM_MESSAGE: &str = "
You are a world-class data analyst, specialising in analysing comma-delimited CSV files.
Your job is to analyse some CSV snippets and determine what the results are for the question that the user is asking.
You should aim to be concise. If you don't know something, don't make it up but say 'I don't know.'.
"
impl MyAgent {
pub fn new(qdrant_client: QdrantClient) -> Self {
let api_key = std::env::var("OPENAI_API_KEY").unwrap();
let config = OpenAIConfig::new().with_api_key(api_key);
let openai_client = OpenAIClient::with_config(config);
Self {
openai_client,
qdrant_client,
}
}
}
```
### File parsing and embedding into Qdrant
Next, we will implement a `File` struct for CSV file parsing - it should be able to hold the file path, contents as well as the rows as a `Vec<String>` (string array, or more accurately a vector of strings). There's a few reasons why we store the rows as a `Vec<String>`:
- Smaller chunks improve the retrieval accuracy, one of the biggest challenges that RAG has to deal with. Retrieving a wrong or otherwise inaccurate document can hamper accuracy significantly.
- Improved retrieval accuracy leads to enhanced contextual relevance - which is quite important for complex queries that require specific question.
- Processing and indexing smaller chunks
```rust
pub struct File {
pub path: String,
pub contents: String,
pub rows: Vec<String>,
}
impl File {
pub fn new(path: PathBuf) -> Result<Self> {
let contents = std::fs::read_to_string(&path)?;
let path_as_str = format!("{}", path.display());
let rows = contents
.lines()
.map(|x| x.to_owned())
.collect::<Vec<String>>();
Ok(Self {
path: path_as_str,
contents,
rows
})
}
}
```
While the above parsing method *is* serviceable (collecting all the lines into a `Vec<String>`), note that it is a naive implementation. Based on how your CSV files are delimited and/or if there is dirty data to clean up, you may want to either prepare your data so that it is already well-prepared, or include some form of data cleaning or validation. Some examples of this might be:
- `unicode-segmentation` - [a library crate for splitting sentences](https://github.com/unicode-rs/unicode-segmentation)
- `csv_log_cleaner` - [a binary crate for cleaning CSVs](https://github.com/ambidextrous/csv_log_cleaner)
- `validator` - [a library crate for validating struct/enum fields](https://github.com/Keats/validator)
Next, we'll go back to our agent and implement a method for embedding documents into Qdrant that will take the `File` struct we defined.
To do this, we need to do the following:
- Take the rows we created earlier and add them as the input for our embed request.
- Create the embeddings (with openAI) and create a payload for storing alongside the embeddings in Qdrant. Note that although we use a `uuid::Uuid` for unique storage, you could just as easily use numbers by adding a number counter to your struct and incrementing it by 1 after you've inserted an embedding.
- Assuming there are no errors, return `Ok(())`
```rust
use async_openai::types::{ CreateEmbeddingRequest, EmbeddingInput };
use async_openai::Embeddings;
use qdrant_client::prelude::{Payload, PointStruct};
static COLLECTION: &str = "my-collection";
// text-embedding-ada-002 is the model name from OpenAI that deals with embeddings
static EMBED_MODEL: &str = "text-embedding-ada-002";
impl MyAgent {
pub async fn embed_document(&self, file: File) -> Result<()> {
if file.rows.is_empty() {
return Err(anyhow::anyhow!("There's no rows to embed!"));
}
let request = CreateEmbeddingRequest {
model: EMBED_MODEL.to_string(),
input: EmbeddingInput::StringArray(file.rows.clone()),
user: None,
dimensions: Some(1536),
..Default::default()
};
let embeddings_result = Embeddings::new(&self.openai_client).create(request).await?;
for embedding in embeddings_result.data {
let payload: Payload = serde_json::json!({
"id": file.path.clone(),
"content": file.contents,
"rows": file.rows
})
.try_into()
.unwrap();
println!("Embedded: {}", file.path);
let vec = embedding.embedding;
let points = vec![PointStruct::new(
uuid::Uuid::new_v4().to_string(),
vec,
payload,
)];
self.qdrant_client
.upsert_points(COLLECTION, None, points, None)
.await?;
}
Ok(())
}
}
```
### Document searching
Now that we’ve embedded our document, we’ll want a way to check whether our embeddings are contextually relevant to whatever prompt the user gives us. For this, we’ll create a `search_document` function that does the following:
- Embed the prompt using `CreateEmbeddingRequest` and get the embedding from the results. We’ll be using this embedding in our document search. Because we’ve only added one sentence to embed here (the prompt), it will only return one sentence - so we can create an iterator from the vector and attempt to find the first result.
- Create a parameter list for our document search through the `SearchPoints` struct (see below). Here we need to set the collection name, the vector that we want to search against (ie the input), how many results we want to be returned if there are any matches, as well as the payload selector.
- Search the database for results - if there are no results, return an an error; if there is a result, then return the result back.
```rust
use qdrant_client::qdrant::{
with_payload_selector::SelectorOptions, SearchPoints, WithPayloadSelector,
};
impl MyAgent {
async fn search_document(&self, prompt: String) -> Result<String> {
let request = CreateEmbeddingRequest {
model: EMBED_MODEL.to_string(),
input: EmbeddingInput::String(prompt),
user: None,
dimensions: Some(1536),
..Default::default()
};
let embeddings_result = Embeddings::new(&self.openai_client).create(request).await?;
let embedding = &embeddings_result.data.first().unwrap().embedding;
let payload_selector = WithPayloadSelector {
selector_options: Some(SelectorOptions::Enable(true)),
};
// set parameters for search
let search_points = SearchPoints {
collection_name: COLLECTION.to_string(),
vector: embedding.to_owned(),
limit: 1,
with_payload: Some(payload_selector),
..Default::default()
};
// if the search is successful
// attempt to iterate through the results vector and find a result
let search_result = self.qdrant_client.search_points(&search_points).await?;
let result = search_result.result.into_iter().next();
match result {
Some(res) => Ok(res.payload.get("contents").unwrap().to_string()),
None => Err(anyhow::anyhow!("There were no results that matched :(")),
}
}
}
```
Now that everything we need to use our agent effectively is set up, we can set up a prompt function!
```rust
use async_openai::types::{
ChatCompletionRequestMessage, ChatCompletionRequestSystemMessageArgs,
ChatCompletionRequestUserMessageArgs, CreateChatCompletionRequestArgs,
};
static PROMPT_MODEL: &str = "gpt-4o";
impl MyAgent {
pub async fn prompt(&self, prompt: &str) -> anyhow::Result<String> {
let context = self.search_document(prompt.to_owned()).await?;
let input = format!(
"{prompt}
Provided context:
{}
",
context // this is the payload from Qdrant
);
let res = self
.openai_client
.chat()
.create(
CreateChatCompletionRequestArgs::default()
.model(PROMPT_MODEL)
.messages(vec![
//First we add the system message to define what the Agent does
ChatCompletionRequestMessage::System(
ChatCompletionRequestSystemMessageArgs::default()
.content(SYSTEM_MESSAGE)
.build()?,
),
//Then we add our prompt
ChatCompletionRequestMessage::User(
ChatCompletionRequestUserMessageArgs::default()
.content(input)
.build()?,
),
])
.build()?,
)
.await
.map(|res| {
//We extract the first one
res.choices[0].message.content.clone().unwrap()
})?;
println!("Retrieved result from prompt: {res}");
Ok(res)
}
}
```
## Hooking the agent up to our web service
Because we separated the agent logic from our web service logic, we just need to connect the bits together and we should be done!
Firstly, we'll create a couple of structs - the `Prompt` struct that will take a JSON prompt, and the `AppState` function that will act as shared application state in our Axum web server.
```rust
#[derive(Deserialize)]
pub struct Prompt {
prompt: String,
}
#[derive(Clone)]
pub struct AppState {
agent: MyAgent,
}
```
We'll also introduce our prompt handler endpoint here:
```rust
async fn prompt(
State(state): State<AppState>,
Json(json): Json<Prompt>,
) -> Result<impl IntoResponse> {
let prompt_response = state.agent.prompt(&json.prompt).await?;
Ok((StatusCode::OK, prompt_response))
}
```
Then we need to parse our CSV file in the main function, create our `AppState` and embed the CSV, as well as setting up our router:
```rust
#[shuttle_runtime::main]
async fn main(
#[shuttle_qdrant::Qdrant] qdrant_client: QdrantClient,
#[shuttle_runtime::Secrets] secrets: SecretStore,
) -> shuttle_axum::ShuttleAxum {
secrets.into_iter().for_each(|x| {
set_var(x.0, x.1);
});
// note that this already assumes you have a file called "test.csv"
// in your project root
let file = File::new("test.csv".into())?;
let state = AppState {
agent: MyAgent::new(qdrant_client),
};
state.agent.embed_document(file).await?;
let router = Router::new()
.route("/", get(hello_world))
.route("/prompt", post(prompt))
.with_state(state);
Ok(router.into())
}
```
## Deploying
To deploy, all you need to do is use `cargo shuttle deploy` (with the `--ad` flag if on a Git branch with uncommitted changes), sit back and watch the magic happen!
## Finishing Up
Thanks for reading! With the power of combining AI agents and RAG, we can create powerful workflows to be able to satisfy many different use cases. With Rust, we can leverage performance benefits to be able to run our workflows safely and with a low memory footprint.

In the... | 0 | 2024-05-24T08:55:44 | https://www.fastly.com/blog/getting-started-with-fastly-cdn-is-easier-than-ever-with-glitch/ | cdn, domains, webdev | We’re making it easier than ever to learn how to deliver your website traffic using Fastly. In the two years since Glitch became part of Fastly, we’ve discovered how valuable it is to be able to give learners a website they can remix at the click of a button and use with a Fastly service. We’re excited to share our first developer guide that comes with a companion Glitch project our community members can use to onboard with Fastly quickly and easily.
## Any tech product is just one piece of a puzzle
The nature of the web today is integration. Sites and applications exist within a complex ecosystem of dependencies that developers need to understand to get good value from any particular product. Many developer products across the industry use Glitch to support adoption and onboarding through low friction, remixable apps that come with help information included right inside the project. At Fastly, being able to teach our tech in the context of a website is crucial when it comes to conveying the purpose and value of what we build.
This is why we’re embarking on a program of learning experiences that leverage Glitch to help users understand technologies like CDNs and edge computing – starting with one on Website Delivery.
Our new guide walks through the flow of creating a website on Glitch and setting up a Fastly CDN service to deliver it to your site visitors, outlining how to use free Fastly TLS to point your domain at your site along the way. The goal is to help you get value from Fastly as quickly and easily as possible, making your websites faster and more reliable in just a few short steps.
## Enabling our internal community
We’ve taken a slightly unusual approach to creating this learning experience by using it for employee training. In the first part of 2024, we used Glitch to teach teams inside the company how to get started working with Fastly services. Glitch helped our coworkers develop their understanding of how Fastly fits into the picture on the web and in the wider world. Basing the training on a Glitch project helped us get people hands-on with Fastly, reaching a valuable learning outcome in a single session, regardless of their role or background.
This training program acted as user testing on the learning experience, so it served a dual purpose of enabling employees with product knowledge and helping us to make these resources as effective as possible for our users. We also opened a rich channel of internal product feedback, resulting in many UX enhancements we were able to action quickly, making the product easier for all who try it going forward.
## Supporting a diverse cohort of learners
People prefer to learn in different ways – some like to work through comprehensive material upfront and scaffold their knowledge methodically, while others prefer to learn through experimentation and play. By providing an interactive Glitch project that mirrors the learning pathway in its companion tutorial, we’re supporting a wider range of learners than we were able to before.
**You can check out our new tutorial now: [Delivering your site through Fastly](http://fastly.com/documentation/solutions/tutorials/deliver-your-site/)**
**You’ll find [the Glitch project](https://glitch.com/~learn-website-delivery) embedded in the page and can remix it for a guided experience inside the Glitch editor.**
**If you get stuck or would like to share feedback, [please post in the community forum](https://community.fastly.com/)!** | suesmith |

1,863,749 | النكهات كانت متقلبة: استكشاف اللوحة العاطفية للطعام | هل سبق لك أن تناولت قضمة من شيء ما وشعرت بموجة غير متوقعة من العاطفة؟ هذه هي قوة النكهات المزاجية.... | 0 | 2024-05-24T08:51:01 | https://dev.to/moodpods02/lnkht-knt-mtqlb-stkshf-llwh-ltfy-lltm-16fi |
هل سبق لك أن تناولت قضمة من شيء ما وشعرت بموجة غير متوقعة من العاطفة؟ هذه هي قوة النكهات المزاجية. هذه النكهات تتجاوز الذوق. فهي تثير المشاعر والذكريات والحالات المزاجية، مما يخلق تجربة طعام شخصية وعاطفية عميقة. دعونا نغوص في عالم النكهات المزاجية ونكتشف كيف يمكن للطعام أن يمس أرواحنا [نكهات بود مزاج
](https://rawqan.com/ps/kHB3vIwBQSUrBgEj8MwV/بودات-مزاج )
العلم وراء إدراك النكهة
إن فهم كيفية إدراكنا للنكهات أمر بالغ الأهمية لفهم تأثيرها العاطفي. تكتشف براعم التذوق لدينا الأذواق الأساسية: الحلو، والمالح، والحامض، والمر، والأومامي. لكن دماغنا هو الذي يعالج هذه الإشارات ويفسرها، وغالبًا ما يتأثر بعلم الوراثة والبيئة. على سبيل المثال، قد يجد بعض الأشخاص الكزبرة منعشة، بينما يتذوق البعض الآخر الصابون بسبب الاختلاف الجيني.
منظور تاريخي على مزاج النكهة
تاريخيًا، كانت للنكهات دائمًا أهمية عاطفية. استخدمت الحضارات القديمة التوابل ليس فقط من أجل الذوق ولكن أيضًا لخصائصها العاطفية والطبية. في العديد من الثقافات، ارتبطت الأطعمة والنكهات المحددة بالطقوس والاحتفالات، التي تهدف إلى إثارة مشاعر أو حالات ذهنية معينة.
النكهة والعاطفة: الاتصال النفسي
النكهات يمكن أن تؤثر بشكل عميق على عواطفنا. فكر في الأطعمة المريحة مثل المعكرونة والجبن أو حساء الدجاج. غالبًا ما تجلب هذه الأطباق إحساسًا بالدفء والأمان، وترتبط بذكريات الحنين للطفولة أو المنزل. هذا الارتباط النفسي هو السبب الذي يجعلنا نتناول في كثير من الأحيان أطعمة معينة خلال فترات الذروة والانخفاضات العاطفية.
اتجاهات الطهي الحديثة والنكهات المزاجية
اليوم، يتبنى عالم الطهي مفهوم النكهات المزاجية. تتزايد تجارب تناول الطعام التجريبية، حيث يقوم الطهاة بإعداد أطباق مصممة لإثارة مشاعر معينة. المطاعم الآن لم تعد مجرد تغذية للمعدة، بل لتغذية الروح أيضًا. على سبيل المثال، يمكن إعداد طبق لاستحضار هدوء الغابة، باستخدام النكهات والروائح الترابية.
دور المكونات في خلق النكهات المزاجية
بعض المكونات لها تأثير مباشر على حالتنا المزاجية. يمكن للتوابل مثل القرفة وجوزة الطيب أن تثير الدفء والراحة، في حين أن الأعشاب مثل الريحان والنعناع قد تجلب إحساسًا بالانتعاش والوضوح. تلعب الكيمياء الكامنة وراء هذه المكونات دورًا حاسمًا في كيفية تأثيرها على عواطفنا.
موازنة النكهات للتأثير العاطفي
إن إعداد طبق بنكهات متقلبة هو فن. أنها تنطوي على موازنة الأذواق الأساسية لتحقيق التأثير العاطفي المطلوب. على سبيل المثال، إضافة لمسة من الحلاوة إلى طبق حار يمكن أن يخلق نكهة مريحة ومثيرة. يمكن للطهاة في المنزل تجربة هذه التوازنات لإعداد وجباتهم الخاصة لتحسين الحالة المزاجية.
تأثير العرض والأجواء
يمكن أن تؤثر طريقة تقديم الطبق بشكل كبير على كيفية إدراكنا لنكهاته. يمكن للوجبة المطلية بشكل جميل أن تجعل تجربة تناول الطعام أكثر متعة وترفع من النكهات. وبالمثل، فإن أجواء بيئة تناول الطعام - الإضاءة والموسيقى والديكور - يمكن أن تعزز أو تقلل من تجربة الأكل العاطفية.
الاختلافات الثقافية في مزاج النكهة
تتعامل الثقافات المختلفة مع النكهات وتأثيراتها العاطفية بشكل فريد. في اليابان، توفر الأطعمة الغنية بالأومامي مثل حساء الميسو شعورًا بالهدوء والرضا. في الهند، يمكن للتوابل النابضة بالحياة المستخدمة في أطباق الكاري أن تنشط وتنشط. إن فهم هذه الاختلافات الثقافية يمكن أن يوسع تقديرنا للنكهات المزاجية.
تجارب النكهة: الطبخ مع مراعاة الحالة المزاجية
يعد الطهي مع مراعاة الحالة المزاجية عملية ممتعة وإبداعية. حاول إعداد طبق مصمم لإثارة مشاعر معينة، مثل تارت الليمون الحامض للحصول على موجة من السعادة أو حلوى الشوكولاتة الغنية للشعور بالرفاهية. تجربة النكهات في المنزل يمكن أن تؤدي إلى اكتشافات طهي مبهجة وغير متوقعة.
مستقبل النكهات المزاجية
يبدو مستقبل النكهات المزاجية واعدًا مع الاتجاهات والتقنيات الناشئة. من فن الطهي الجزيئي إلى الوصفات التي ينشئها الذكاء الاصطناعي، فإن الاحتمالات لا حصر لها. من المرجح أن تؤدي هذه التطورات إلى تجارب طعام أكثر تخصيصًا وعاطفية.
الصحة والرفاهية: تأثير النكهات المزاجية
العلاقة بين النكهة والمزاج والصحة العقلية مهمة. الأطعمة التي تثير المشاعر الإيجابية يمكن أن تساهم في الصحة العامة. إن دمج الأطعمة المعززة للمزاج في نظامنا الغذائي يمكن أن يساعد في إدارة التوتر وتحسين الصحة العقلية.
النكهة وسرد القصص: رواية الطعام
غالبًا ما يستخدم الطهاة النكهات لسرد القصص، مما يخلق قصة يمكن لرواد المطعم تجربتها من خلال الذوق. يمكن أن تثير هذه القصة مشاعر قوية، مما يجعل تجربة تناول الطعام لا تُنسى. فكر في طبق مستوحى من ذكريات الطفولة، مصمم لإثارة الحنين والفرح.
النكهات هي أكثر من مجرد أذواق؛ إنها أدوات قوية يمكنها إثارة مجموعة واسعة من المشاعر. ومن خلال فهم النكهات المتقلبة وتجربتها، يمكننا إنشاء تجارب تناول طعام ليست لذيذة فحسب، بل ذات معنى عميق أيضًا. لذا، في المرة القادمة التي تكون فيها في المطبخ، فكر في المشاعر التي تريد إثارةها ودع مكوناتك ترشدك.

### Why Unit Testing in Front-end Development?
Unit testing, a fundamental aspect of software development, plays a pivotal role in ensuring the functionality and reliability of individual units or components of code. In the context of front-end development, it serves as a critical tool for developers to identify and rectify errors before they escalate to the end user, thereby maintaining the integrity of the application. The process of unit testing allows developers to detect errors early in the development cycle, facilitating a smoother and more efficient debugging process. By isolating and testing individual pieces of code, developers can ensure each component operates as expected, significantly reducing the time and effort required for error resolution.
### Benefits of Unit Testing
**Early Error Detection**: One of the primary advantages of unit testing is its ability to uncover bugs and errors at an early stage. This preemptive approach to error management not only conserves development time but also simplifies the process of rectifying issues before they integrate with other parts of the application.
**Facilitates Code Refactoring**: Refactoring, or the process of modifying code to enhance its efficiency and maintainability without altering its external behaviour, is crucial for the longevity of software applications. Unit testing supports this process by providing a safety net, ensuring that modifications do not introduce new errors or compromise existing functionality.
**Improves Code Coverage**: Code coverage, indicative of the extent to which the codebase is tested, is a key metric in assessing the quality of the application. Through unit testing, developers can identify untested segments of the code, thereby increasing coverage and confidence in the application’s reliability.
**Enhances Code Quality**: The rigorous nature of unit testing compels developers to thoroughly examine the functionality and potential failure points of their code. This introspective approach promotes the development of robust, reliable, and maintainable code, ultimately improving the overall quality of the software.
**Promotes Better Design**: The necessity to isolate and test code units independently encourages developers to adopt modular and decoupled coding practices. This not only makes the code more testable but also enhances its readability and scalability.
### The Role of Unit Testing in Front-End Development
Front-end development involves the creation and management of the user interface, encompassing elements like formatting, visible text, graphics, and interactive components such as buttons and forms. Unit testing is instrumental in ensuring these elements function correctly across different scenarios and user interactions. By focusing on individual components and functions, unit testing verifies that they perform as intended, laying the foundation for a stable and reliable application.
Given the complexity and diversity of user interface elements, prioritizing tests becomes essential. Developers often start by ensuring basic functionality, such as text visibility and page loading, before progressing to more complex interactive features. This structured approach to testing ensures comprehensive coverage, from the layout and aesthetics to the responsiveness and execution of user requests.
### Conclusion
Unit testing is an indispensable component of front-end development, offering a multitude of benefits ranging from early error detection to improved code quality and design. By adopting a systematic approach to unit testing, developers can ensure their applications meet the highest standards of functionality and reliability, ultimately delivering a superior user experience.
### Setting Up Jest and Enzyme
**Installing Required Packages**
For developers starting with a new React application, it is recommended to utilize the Create React App, which comes pre-configured with Jest. This setup simplifies the process as it only requires the addition of a react-test-renderer for rendering snapshots. For those working on an existing application, several packages need to be installed to integrate Jest and Enzyme properly. Key packages include babel-jest for code transformation within the test environment and the react babel preset. These tools work together to ensure that the testing environment mimics the actual application environment.
**Configuring Enzyme**
Once the necessary packages are installed, setting up Enzyme involves creating a setupTests.js file within the src/ directory of the project. This file is crucial as it configures the Enzyme adapter, which is essential for testing React components. Ensure the file includes the appropriate imports and configuration settings, such as:
```javascript
import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
Enzyme.configure({ adapter: new Adapter() });
```
This configuration sets up Enzyme with the specified adapter, which should match the React version used in the project. It is also possible to configure Enzyme globally through the package.json by adding a jest entry to specify the setupTestFrameworkScriptFile, which points to the setupTests.js file. This approach avoids the need to import the setup file in each test file.
**Adding Scripts**
To fully integrate Jest and Enzyme into the development workflow, it is necessary to add specific scripts to the package.json file. These scripts will facilitate the running of tests and the generation of coverage reports. The typical entries in the package.json should include:
```json
"scripts": {
"test": "jest",
"test:coverage": "jest --coverage"
}
```
These scripts enable developers to execute tests using Jest and to collect coverage information, which helps in identifying untested parts of the application. The coverage report provides insights into the effectiveness of the tests and highlights areas that may require additional testing.
By following these steps—installing the required packages, configuring Enzyme, and adding necessary scripts—developers can set up a robust testing environment using Jest and Enzyme for their React applications. This setup not only supports the development of reliable and maintainable code but also enhances the overall testing workflow.
### Writing Unit Tests with Jest and Enzyme
Writing unit tests is a critical step in ensuring the robustness of React applications. Jest, a testing tool developed by Facebook, simplifies unit testing in JavaScript, while Enzyme, specific to React, provides methods that enhance the testing of React components. This section delves into creating test cases, running tests, and handling snapshots with Jest and Enzyme, guiding developers through the process of establishing a reliable testing environment for React applications.
**Creating Test Cases**
To begin with, developers should create a React application that can be tested. A simple counter app, which increments a count upon a button click, serves as a practical example. Using Create React App allows developers to quickly set up a project with Jest pre-installed, eliminating the need for additional configuration steps.
1. **Initialize the Application**: Bootstrap the project using Create React App to quickly start with a setup that includes Jest.
2. **Write the First Test**: Utilize Enzyme's shallow rendering for testing the app's initial state. Shallow rendering enables testing a component without requiring a DOM, by rendering only one level deep.
3. **Simulate User Interaction**: Employ Enzyme's simulate() function to mimic user interactions, such as clicking a button, and set expectations for the application's response to these interactions.
**Running Tests**
Running tests is streamlined with Jest. Once test cases are written, developers can execute them to verify the behaviour of their React components.
1. **Execute Tests**: Use the jest command to run the tests. This command looks for files with .test.js or .test.jsx extensions and executes the tests contained within.
2. **Review Test Output**: Analyze the output produced by running the tests. Jest will indicate whether the tests passed or failed, allowing developers to identify and address any issues.
**Handling Snapshots**
Snapshot testing is a powerful feature of Jest that helps ensure the UI does not change unexpectedly. It involves rendering a UI component, taking a snapshot, and comparing it to a reference snapshot file.
1. **Generate Snapshots**: When a snapshot test is executed for the first time, Jest generates a snapshot of the component's rendered output and stores it in a JSON file. This snapshot serves as a reference for future test runs.
2. **Compare to Reference Snapshot**: On subsequent test runs, Jest compares the current rendered output of the component against the stored snapshot. If there are deviations, Jest notifies the developer, who can then decide whether to update the snapshot or address the changes in the component.
3. **Update Snapshots**: If changes to the component are intentional and the snapshot needs to be updated, developers can use the jest -u command to update the existing snapshot to match the new version of the UI component.
By following these steps, developers can leverage Jest and Enzyme to create comprehensive unit tests for React applications. This process not only ensures the reliability and stability of the application but also facilitates a smoother development cycle by enabling early detection and resolution of issues.
### Advanced Techniques and Best Practices
**Mocking and Spying**
Mock functions, also known as "spies," are essential in testing the behaviour of functions that are called indirectly by other codes. By creating a mock function
with jest.fn(), developers can monitor and assert the behaviour of these functions, including their calls, results, and instances. For instance, to mock or spy on React's useState hook, developers can employ jest.spyOn() to observe the state changes within components. This technique is particularly useful in ensuring that components respond correctly to user interactions or internal state changes.
**Snapshot Testing**
Snapshot testing is a powerful tool for ensuring UI consistency. By rendering a UI component and comparing it to a reference snapshot file, developers can detect unexpected changes. This method is favoured for its simplicity and effectiveness in catching unintended modifications to the UI. Jest enhances this process by using a pretty format to make snapshots human-readable, which is crucial for code reviews. Developers are encouraged to commit snapshots and treat them as part of the regular code review process, ensuring that snapshots remain focused, short, and readable. It's important to remember that snapshot testing complements, rather than replaces, traditional unit testing, offering additional value and making testing more efficient.
**TDD and BDD**
Test-Driven Development (TDD) and Behavior-Driven Development (BDD) are methodologies that guide the development process through testing. TDD follows a Red-Green-Refactor cycle, where tests are written before the code, ensuring that the software design is led by tests. This approach helps in preventing future regressions and increases confidence in the code's functionality. However, it's acknowledged that TDD can be time-consuming and challenging, especially when testing edge cases. BDD, on the other hand, extends TDD by specifying behaviour in a more readable and understandable language, allowing for better communication among stakeholders and ensuring that the software behaves as intended. Both methodologies emphasize the importance of testing in maintaining and refactoring code, thereby preventing the creation of legacy code.
Incorporating these advanced techniques and best practices into the development workflow significantly enhances the quality and reliability of software. By employing mocking and spying, developers gain deeper insights into the behaviour of their applications. Snapshot testing ensures UI consistency, and the adoption of TDD and BDD methodologies guides the development process with a focus on testing, ultimately leading to more maintainable and error-free code.
### Conclusion
Throughout this article, we've navigated the depths of Jest and Enzyme to uncover their roles in enhancing the React development experience, rooted in the principles of behaviour-driven development. We've delved into setting up, configuring, and employing these powerful tools to ensure our React components behave as intended, demonstrating their pivotal role in the early detection of errors, facilitating smoother code refactoring, and ultimately bolstering code quality and maintainability. This comprehensive exploration underscores the necessity of integrating these testing frameworks into the development workflow, highlighting their indispensable value in crafting robust, reliable, and bug-free applications.
As we conclude, it's clear that the adoption of Jest and Enzyme goes beyond mere testing; it represents a commitment to excellence in software development. The journey through unit testing, mocking, snapshot testing, and the embrace of TDD and BDD practices illuminates a path towards achieving higher standards of code integrity and application functionality. Encouraging further exploration and continuous learning in these areas promises to elevate the quality of React projects, underscoring a culture of rigorous testing and meticulous development. Embracing these tools and methodologies is not just about preventing errors but about forging software that stands the test of time, technically.

1,863,743 | Modern C# Development: Get Started With TimeOnly | Hi lovely readers, We probably all know the pain of using DateTime while just needing a date without... | 0 | 2024-05-24T08:43:05 | https://dev.to/lovelacecoding/modern-c-development-get-started-with-timeonly-53ej | dotnet, csharp, programming, beginners | Hi lovely readers,
We probably all know the pain of using DateTime while just needing a date without time, or a time without a day. Well, .NET came with a solution that still isn’t that widely used. In this blog post, we’re going to focus on the data type TimeOnly.
Does your application heavily rely on time and not date? Do you hate time zones and do you rather not deal with them? Do you want to learn how to make your time variables even better, and easier to serialize? Continue reading and I’ll show you how.
## Why TimeOnly
TimeOnly is great in situations where you’re heavily focused on Time. Here are some scenarios where TimeOnly proves to be a great alternative to DateTime:
1. **Simplicity and Readability:**
When your application deals primarily with event times that don’t necessarily need dates, TimeOnly provides a better option.
2. **Database Operations:**
Working with databases that store time information without date becomes seamless with TimeOnly.
3. **Comparisons:**
TimeOnly is a great pick if your logic involves comparing two TimeOnly objects and how much time is in between them. It has methods built in to compare time.
4. **Consistency in Codebase:**
For codebases that heavily rely on time, using TimeOnly throughout helps with consistency.
5. **Avoiding Time Zone Complexity:**
Because TimeOnly doesn’t focus on dates, you don’t have time zone complexities at all. This makes working with TimeOnly way easier.
## How to use TimeOnly
Now that we've explored why TimeOnly is a great choice in multiple scenarios, let's dive into how to use TimeOnly in your C# projects.
### **Initialize TimeOnly**
Creating a TimeOnly instance is straightforward. You can set a specific time using the constructor like this:
```csharp
TimeOnly specificTime = new TimeOnly(11,30); //hour, minute
TimeOnly specificTime2 = new TimeOnly(11,30,45); //hour, minute, second
TimeOnly specificTime3 = new TimeOnly(11,30,45,100); //hour, minute, second, millisecond
TimeOnly specificTime4 = new TimeOnly(11,30,45,100, 4); //hour, minute, second, millisecond, microsecond
```
If you want to initialize a TimeOnly variable with the time right now, you can use the ‘FromDateTime’ method:
```csharp
TimeOnly timeNow = TimeOnly.FromDateTime(DateTime.Now);
```
You can write it to the console like every other variable:
```csharp
Console.WriteLine(specificTime); //11:30
Console.WriteLine(timeNow); //Whatever time it is right now in hh:mm
```
Whether you get to see a 24-hour clock or 12-hour clock depends on the settings of your machine.
### **Formatting the TimeOnly value**
Of course, you can format this TimeOnly variable differently based on whatever country/culture you want to focus on. You can use the System.Globalization package for this.
From the 24-hour system to the USA AM/PM system:
```csharp
using System.Globalization;
TimeOnly specificTime = new TimeOnly(11,30); //hour, minute
CultureInfo ci = CultureInfo.GetCultureInfo("en-US");
Console.WriteLine(specificTime.ToString(ci));
```
From USA AM/PM system to the European 24-hour system:
```csharp
using System.Globalization;
TimeOnly specificTime = new TimeOnly(11,30); //hour, minute
CultureInfo ci = CultureInfo.GetCultureInfo("en-GB");
Console.WriteLine(specificTime.ToString(ci));
```
## Logic with TimeOnly
TimeOnly supports time operations like adding or subtracting hours or minutes. Here's how you can do it.
Adding and Subtracting Time:
```csharp
TimeOnly timeNow = TimeOnly.FromDateTime(DateTime.Now);
TimeOnly timeNowPlusAnHour = timeNow.AddHours(1);
TimeOnly timeNowMinusAnHour = timeNow.AddHours(-1);
TimeOnly timeNowPlusAMinute = timeNow.AddMinutes(1);
TimeOnly timeNowMinusAMinute = timeNow.AddMinutes(-1);
```
### **Serialization**
Serialization is often crucial when dealing with dates in applications. TimeOnly simplifies this process. For instance, when working with JSON:
```csharp
using System.Text.Json;
TimeOnly specificTime = new TimeOnly(11,30); //hour, minute
string json = JsonSerializer.Serialize(specificTime);
TimeOnly deserializedTime = JsonSerializer.Deserialize<TimeOnly>(json);
Console.WriteLine(deserializedTime); // 11:30
```
### Conditions
You can use if-else conditions, switch cases, or switch expressions with TimeOnly
```csharp
TimeOnly specificTime = new TimeOnly(11,30); //hour, minute
TimeOnly timeLater = new TimeOnly(11,35); //hour, minute
if(specificTime > timeLater)
{
Console.WriteLine("specificTime is later than timeLater");
}
else
{
Console.WriteLine("specificTime is not later than timeLater");
}
```
### Compare two TimeOnly objects
You can compare two TimeOnly objects and store that value in another variable. This variable will become a TimeSpan data type
```csharp
TimeOnly specificTime = new TimeOnly(11,30); //hour, minute
TimeOnly timeLater = new TimeOnly(11,35); //hour, minute
TimeSpan difference = timeLater-specificTime;
Console.WriteLine(difference); // 00:05:00
```
It will also work with more precise TimeOnly objects where you have to compare microseconds
```csharp
TimeOnly specificTime = new TimeOnly(11,30,00,00,00); //hour, minute, second, millisecond, microsecond
TimeOnly timeLater = new TimeOnly(11,30,00,00,02); //hour, minute, second, millisecond, microsecond
TimeSpan difference = timeLater-specificTime;
Console.WriteLine(difference); // 00:00:00.0000020
```
## That’s a wrap!
So in conclusion, TimeOnly offers simplicity, readability, and consistency when working with times in C# applications. By focusing solely on time and ignoring dates, it streamlines operations like database storage, user interfaces, and comparisons. Whether you're developing scheduling software, logging systems, or any other application reliant on time, TimeOnly can enhance your workflow and codebase.

1,863,737 | How to bind the click event of the pie chart label in @visactor/vchart? | Problem Description As shown in the pie chart below, how can I achieve a custom callback... | 0 | 2024-05-24T08:37:26 | https://dev.to/tinglittlekang/how-to-bind-the-click-event-of-the-pie-chart-label-in-visactorvchart-4e2b | ## Problem Description
As shown in the pie chart below, how can I achieve a custom callback when clicking on a label?
## Solution
In VChart, the label component does not respond to events by default. This is mainly to avoid affecting the event response of the main chart elements when the labels are dense. To achieve event listening of labels, you need to take two steps:
- Enable label event response by setting `label.interactive` to `true`
- Implement event listening of label components through `{ level: 'model', type: 'label' }`
## Code Examples
```
const spec = {
type: 'pie',

How to set the maximum number of X-axis and Y-axis labels?
## Problem Description
In the following chart, the labels on the x-axis are displayed quite densely. Can we limit the maximum number of labels? Make the x-axis labels look better visually, while all points on the line need to be displayed.
## Solution
In VChart, the number of axis labels is affected by various configurations. There are two ways to limit the number of axis labels:
- Set `sampling` to `true` so that sampling will be automatically performed according to the width of the labels.
- Set `tick.tickCount` to specify the number of labels.

1,863,735 | Mastering Python Conditional Statements: A Comprehensive Guide | Python, renowned for its simplicity and versatility, is a preferred language for both beginners and... | 0 | 2024-05-24T08:32:27 | https://dev.to/markwilliams21/mastering-python-conditional-statements-a-comprehensive-guide-54e4 | python, programming, webdev, javascript | Python, renowned for its simplicity and versatility, is a preferred language for both beginners and experienced developers. One of the core aspects of Python, enabling it to manage logic and flow control effectively, is its conditional statements. These statements allow the execution of code blocks based on specific conditions, making your programs dynamic and intelligent. This article delves into the intricacies of [Python's conditional statements](https://www.janbasktraining.com/blog/python-if-else-elif-nested-if-and-switch-case/), exploring their syntax, applications, and best practices.
## The Basics: if Statement
At the heart of Python's conditional statements lies the if statement. The if statement evaluates a condition (an expression that results in a Boolean value, True or False). If the condition is true, the indented block of code following the if statement executes.
`age = 18
if age >= 18:
print("You are eligible to vote.")`
In this example, the condition age >= 18 is checked. Since the condition is true, the message "You are eligible to vote." is printed.
**Adding Complexity: elif and else Clauses**
For scenarios requiring multiple conditions, Python provides the elif (short for else if) and else clauses. These allow for more complex decision-making processes.
`score = 85
if score >= 90:
print("Grade: A")
elif score >= 80:
print("Grade: B")
elif score >= 70:
print("Grade: C")
else:
print("Grade: F")`
Here, multiple conditions are checked in sequence. The first condition that evaluates to true will trigger its corresponding block of code. If none of the conditions are true, the else block executes.
## Nesting Conditional Statements
Conditional statements can be nested to create more sophisticated logic flows. However, it's essential to maintain clear and readable code to avoid confusion.
`num = 10
if num > 0:
print("Positive number")
if num % 2 == 0:
print("Even number")
else:
print("Odd number")
else:
print("Negative number")`
In this example, the program first checks if num is positive. If true, it then checks if num is even or odd. Nesting allows you to construct detailed and layered decision-making processes.
**Using Conditional Expressions (Ternary Operators)**
For simpler conditions, Python offers conditional expressions, also known as ternary operators. These allow you to condense an if-else statement into a single line.
`status = "even" if num % 2 == 0 else "odd"
print(f"The number is {status}.")`
This one-liner is equivalent to:
`if num % 2 == 0:
status = "even"
else:
status = "odd"
print(f"The number is {status}.")`
## Best Practices for Writing Conditional Statements
**Clarity and Readability:** Write conditions that are easy to read and understand. Avoid overly complex expressions and deeply nested conditions.
**Consistent Indentation:** Python relies on indentation to define code blocks. Ensure consistent use of spaces or tabs to avoid syntax errors.
**Logical Flow: **Structure your conditions logically. Check for the most likely conditions first to enhance efficiency.
**Avoid Redundancy:** Eliminate unnecessary checks. For instance, in the grading example above, once score >= 90 is checked, there is no need to check for score < 90 in subsequent conditions.
**Use Comments:** For complex logic, use comments to explain your conditions. This aids in maintaining and understanding the code in the future.
## Advanced Topics: Boolean Operators
Python’s [Boolean operators](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/boolean-logical-operators) and, or, and not can combine multiple conditions or negate conditions to create more nuanced logic.
`temperature = 22
humidity = 65
if temperature > 20 and humidity < 70:
print("It's a nice day.")`
Here, the message prints only if both conditions are true. Using or would print the message if either condition is true, and not would negate the condition.
**Conclusion**
Mastering conditional statements in Python is essential for building logical, efficient, and readable code. From simple if statements to complex nested conditions, Python’s straightforward syntax and powerful features provide the tools needed to handle any decision-making process. By following best practices and understanding the intricacies of conditional logic, you can enhance your programming skills and write more effective [Python programs](https://www.javatpoint.com/python-programs). | markwilliams21 |

1,863,732 | MTTR Deep Dive: A Technical Guide for Engineering Managers & Leaders | In the world of software development, where every minute of downtime can translate to significant... | 0 | 2024-05-24T08:27:39 | https://www.middlewarehq.com/blog/mttr-deep-dive-a-technical-guide-for-engineering-managers-leaders | coding, productivity, tooling | In the world of software development, where every minute of downtime can
translate to significant revenue loss and reputational damage, Mean Time to Restore (MTTR) is a critical metric that can help your software retain its most valuable customers and help you improve the overall LTV.
While MTTR is often overshadowed by its flashier [ DORA siblings
](https://www.middlewarehq.com/blog/a-blueprint-for-predictable-software-
delivery-with-dora-metrics) (Deployment Frequency and Lead Time for Changes), it does offer a unique lens into your team's ability to respond to and recover from incidents swiftly.
Let's take a deeper look into MTTR, its implications for your engineering org, and actionable strategies to optimize it.
## Understanding MTTR: Beyond the Basics
MTTR, in its simplest form, measures the average time it takes to restore
service after an incident or failure. This encompasses everything from the
moment an incident is detected to the point where the system is fully
operational again.
But MTTR is more than just a number on a dashboard.
It's a reflection of your organization's resilience, incident response
processes, and ultimately, the customer experience you deliver. A high MTTR indicates potential weaknesses in your processes, tooling, or team
coordination.
## Why MTTR Matters More Than You Think
MTTR is intrinsically linked to several key areas of your engineering
organization's health:
* **Customer Satisfaction and Trust:** Frequent or prolonged outages degrade user confidence and can drive them to your competitors. A low MTTR demonstrates a commitment to reliability and a swift response to disruptions.
* **Operational Efficiency:** High MTTR often indicates manual, inefficient processes for incident detection, diagnosis, and remediation. This can drain valuable engineering resources that could be better spent on innovation and feature development.
* **Financial Impact:** In many industries, especially those with high transaction volumes (e.g., e-commerce, finance), downtime directly translates to lost revenue. By reducing MTTR, you protect your bottom line.
## It’s a Dynamic Metric
MTTR is not a monolithic measurement. To gain a comprehensive understanding, it's crucial to analyze it from multiple angles:
* **MTTR by Severity:** Categorize incidents by severity (critical, major, minor) to prioritize and address the most impactful issues first.
* **MTTR by Service/Component:** Identify the specific services or components most prone to outages or failures, highlighting potential architectural weaknesses.
* **MTTR Trends Over Time:** [ Track how your MTTR changes over time ](https://demo.middlewarehq.com/) . Is it decreasing, indicating improvement, or increasing, signaling potential problems with scaling or recent changes?
## Technical Strategies for Lowering MTTR
1. **Comprehensive Monitoring & Alerting: ** Invest in a robust monitoring stack that provides visibility into your system's health. Fine-tune alerting thresholds to catch anomalies early, allowing for proactive intervention before an incident escalates. You can get started with [ Middleware Open Source and improve visibility and predictability ](https://github.com/middlewarehq/middleware) through all DORA metrics including MTTR.
2. **Automated Incident Detection:** Leverage AI/ML algorithms to analyze logs, metrics, and traces, automatically identifying potential issues and triggering alerts. This can significantly reduce the time spent on manual investigation.
3. **Incident Response Playbooks:** Create detailed internal documentation for common incident types, outlining step-by-step procedures, escalation paths, and communication templates. This ensures a consistent and efficient response, even under pressure.
4. **Blameless Postmortems:** Foster a culture of learning from mistakes. Analyze every incident without blame, identify root causes, and implement corrective actions.
5. **Continuous Improvement:** Regularly review and refine your incident response processes, incorporating lessons learned from past events.
## Your Team Makes All The Difference
* **Empowerment:** Give engineers ownership over their systems and the freedom to experiment with solutions.
* **Psychological Safety:** Create a blameless culture where developers feel safe reporting issues and sharing learnings.
* **Training & Knowledge Sharing: ** Invest in regular training sessions and knowledge sharing to ensure your team is equipped to handle diverse incidents effectively.
## Parting Thoughts
In the fast-paced world of software development, where every second counts, a low MTTR is no longer a luxury, it's a necessity.
By understanding and optimizing MTTR, you can build a more resilient system, deliver a superior customer experience, and create a high-performing engineering team that embraces challenges and thrives under pressure.

1,863,731 | Die besten 20 KI-Tools [2024] | KI verändert gerade von unseren Augen die Welt, aber viele wissen nicht, wie sie es täglich... | 0 | 2024-05-24T08:24:55 | https://dev.to/emilia/die-besten-20-ki-tools-2024-1mgo | ai, programming, beginners, python | KI verändert gerade von unseren Augen die Welt, aber viele wissen nicht, wie sie es täglich einsetzten können.
Hier sind 20 AI-Tools, mit denen Sie jeden Tag 5 Stunden Arbeit sparen können, lästige Aufgaben abgeben, viel produktiver werden und Ihr komplettes Potenzial entfesseln können. Jetzt fangen wir an!
Was ist KI (Künstliche Intelligenz)?
AI (Künstliche Intelligenz) steht für “Artificial Intelligence”. Ein Computer mit einer Intelligenz, die dem menschlichen Gehirn ähnelt und die sich durch eigenständiges Lernen ohne menschliche Befehle oder Anweisungen auszeichnet.
Arten von Werkzeugen der künstlichen Intelligenz
Werkzeuge der künstlichen Intelligenz lassen sich grob in die folgenden Kategorien einteilen:
Plattformen für maschinelles Lernen
Maschinelles Lernen ist eine Technik, bei der Computer eigenständig und ohne menschliche Hilfe lernen. Ein Beispiel dafür ist die automatische Kategorisierung von Bildern von Hunden und Katzen. Durch die Verarbeitung großer Datenmengen erkennt der Computer automatisch Muster und lernt Regeln.
Das maschinelle Lernen extrahiert Regeln aus umfangreichen Datenmengen, ohne dass der Mensch sie manuell erstellen muss. Diese Technologie wird in verschiedenen Bereichen wie dem autonomen Fahren, der Spracherkennung, der Bilderkennung usw. eingesetzt. Allerdings sind präzise Daten für die richtigen Ergebnisse unerlässlich, und das Training kann sehr zeitaufwändig sein.
Deep learning
Deep Learning ist eine Art des maschinellen Lernens, das durch die Verarbeitung großer Datenmengen Probleme mit hoher Genauigkeit lösen kann. Es wird in Bereichen wie Bilderkennung, Spracherkennung und Verarbeitung natürlicher Sprache eingesetzt.
Die Vorverarbeitung von Daten ist zwar einfacher als bei herkömmlichen Methoden, erfordert aber große Datenmengen und eine hohe Rechenleistung und kann in der Umsetzung teuer sein.
Verarbeitung natürlicher Sprache
Die Verarbeitung natürlicher Sprache (Natural Language Processing, NLP) ist eine Technologie, die Computer zur Verarbeitung menschlicher Sprache einsetzt. Sie versteht die Bedeutung von Texten und wird für die automatische Übersetzung, Satzgenerierung, Stimmungsanalyse, Informationsbeschaffung, Spracherkennung usw. verwendet. NLP wird mit Techniken wie maschinellem Lernen und Deep Learning ausgeführt. Heute wird es in Wirtschaft, Medizin, Recht, Verwaltung und Bildung eingesetzt.
Allerdings sind Wörter mehrdeutig und können nicht vollständig automatisch verarbeitet werden. NLP erfordert außerdem große Datenmengen und eine hohe Rechenleistung.
Bilderkennung
Bei der Bilderkennung handelt es sich um eine Technologie, die es einem Computer ermöglicht, ein Foto oder Video zu betrachten und zu bestimmen, was darauf zu sehen ist. Sie nutzt Techniken wie maschinelles Lernen und Deep Learning, um automatisch Muster und Merkmale in Fotos und Videos zu erkennen und so unbekannte Objekte mit hoher Genauigkeit zu identifizieren.
Sie wird derzeit in Szenarien wie Überwachungskameras, selbstfahrenden Autos, medizinischen Untersuchungen, Produktinspektionen und Gesichtserkennung eingesetzt. Die Erkennung kann jedoch aufgrund von Auflösung, Beleuchtung, Winkel und verdeckten Teilen schwierig sein. Um die Genauigkeit zu verbessern, ist daher ein integriertes Lernen erforderlich, das mehrere Methoden kombiniert oder eine große Anzahl von Fotos und Videos verwendet.
Andere Werkzeuge der künstlichen Intelligenz
Neben maschinellem Lernen, Deep Learning, natürlicher Sprachverarbeitung und Bilderkennung gibt es noch viele andere Arten von KI-Tools.
Zum Beispiel Roboter-Frameworks zur Steuerung von Robotern, Sprachsynthese-Engines zur Implementierung von Sprachsynthesetechniken, Sensordatenverarbeitungs-Tools zur Analyse von Sensordaten aus selbstfahrenden Autos oder Kundenanalyse-Tools zur Vorhersage von Kundenverhalten.
Diese Tools sind auf ihre jeweiligen Bereiche ausgerichtet und verfügen über unterschiedliche Funktionen und Merkmale. Beispielsweise sind Robotik-Frameworks auf die Bewegungssteuerung und Sensorik von Robotern ausgerichtet, und Sensordatenverarbeitungstools dienen der Verarbeitung von Sensordaten in Echtzeit. Darüber hinaus visualisieren Kundenanalysetools Geschäftsdaten und unterstützen Geschäftsentscheidungen.
Aufgrund der Vielfalt und Spezialisierung der KI-Tools ist es wichtig, sie entsprechend Ihrem Zweck auszuwählen.
Diese Tools können einzeln oder in Kombination verwendet werden, um bestimmte Probleme zu lösen oder komplexe Arbeitsabläufe zu automatisieren. Da die KI-Technologie weiter voranschreitet, entstehen neue Tools und Anwendungsbereiche.

1,863,698 | word clouds with python ☁️🐍 | Creating Word Clouds with WordCloud module in Python Word clouds are a visually appealing... | 0 | 2024-05-24T08:20:13 | https://dev.to/kammarianand/word-clouds-with-python-2do1 | python, nlp, datascience, visulaization | ## Creating Word Clouds with WordCloud module in Python
Word clouds are a visually appealing way to represent the frequency of words in a text. They help in quickly identifying the most prominent terms, providing insights into the main themes and topics. In this article, we'll explore how to generate a word cloud using the `wordcloud` library in Python. We'll also use `matplotlib` for displaying the word cloud.
### Prerequisites
To follow along, ensure you have the following libraries installed:
```sh
pip install wordcloud
pip install matplotlib
```
### </> Example Code
Below is a Python script that generates a word cloud from a given text about Steve Jobs. The script leverages the wordcloud library to create the word cloud and matplotlib to display it.
```python
import matplotlib.pyplot as plt
from wordcloud import WordCloud
text = '''
Steven Paul Jobs was an American businessman, inventor, and investor best known for co-founding the technology giant Apple Inc. Jobs was also the founder of NeXT and chairman and majority shareholder of Pixar.
He was a pioneer of the personal computer revolution of the 1970s and 1980s, along with his early business partner and fellow Apple co-founder Steve Wozniak.
Jobs was born in San Francisco in 1955 and adopted shortly afterwards. He attended Reed College in 1972 before withdrawing that same year. In 1974, he traveled through India, seeking enlightenment before later studying Zen Buddhism.
He and Wozniak co-founded Apple in 1976 to further develop and sell Wozniak's Apple I personal computer. Together, the duo gained fame and wealth a year later with production and sale of the Apple II, one of the first highly successful mass-produced microcomputers.
Jobs saw the commercial potential of the Xerox Alto in 1979, which was mouse-driven and had a graphical user interface (GUI). This led to the development of the unsuccessful Apple Lisa in 1983, followed by the breakthrough Macintosh in 1984, the first mass-produced computer with a GUI.
The Macintosh launched the desktop publishing industry in 1985 with the addition of the Apple LaserWriter, the first laser printer to feature vector graphics and PostScript.
'''
wc = WordCloud().generate(text)
plt.figure(figsize=(10, 5))
plt.imshow(wc)
plt.axis('off')
plt.show()
```
### output
### Explanation
* Import Libraries: We import matplotlib.pyplot for visualization and WordCloud from the wordcloud library for generating the word cloud.
* Text Data: The variable text contains a multiline string about Steve Jobs, which serves as the input for our word cloud.
* Generate Word Cloud: The WordCloud().generate(text) method creates the word cloud from the input text.
* Display Word Cloud: We use matplotlib to display the generated word cloud. `plt.imshow(wc)` displays the image, and `plt.axis('off')` removes the axes for a cleaner look.
### WordCloud Parameters
The `WordCloud` class provides several parameters to customize the appearance and behavior of the word cloud. Below is a table summarizing the key parameters:

## Configuring CMakeLists.txt for Building C++ Applications
The target project relies on header files, shared libraries, JSON-formatted templates, and neural network models. To simplify the build process, we can use CMake to manage dependencies and generate project files for different platforms.
1. Specify the directories for header files and shared libraries:
```cmake
if(WINDOWS)
if(CMAKE_CXX_COMPILER_ID STREQUAL "GNU")
link_directories("${PROJECT_SOURCE_DIR}/../sdk/platforms/win/bin/")
else()
link_directories("${PROJECT_SOURCE_DIR}/../sdk/platforms/win/lib/")
endif()
elseif(LINUX)
if (CMAKE_SYSTEM_PROCESSOR STREQUAL x86_64)
MESSAGE( STATUS "Link directory: ${PROJECT_SOURCE_DIR}/../sdk/platforms/linux/" )
link_directories("${PROJECT_SOURCE_DIR}/../sdk/platforms/linux/")
endif()
endif()
include_directories("${PROJECT_BINARY_DIR}" "${PROJECT_SOURCE_DIR}/../sdk/include/")
```
2. Link the required libraries:
```cmake
add_executable(${PROJECT_NAME} main.cxx)
if(WINDOWS)
if(CMAKE_CL_64)
target_link_libraries (${PROJECT_NAME} "DynamsoftCorex64" "DynamsoftLicensex64" "DynamsoftCaptureVisionRouterx64" "DynamsoftUtilityx64" ${OpenCV_LIBS})
endif()
else()
target_link_libraries (${PROJECT_NAME} "DynamsoftCore" "DynamsoftLicense" "DynamsoftCaptureVisionRouter" "DynamsoftUtility" pthread ${OpenCV_LIBS})
endif()
```
3. Copy the required shared libraries, JSON files and neural network models to the output directory:
```cmake
if(WINDOWS)
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy_directory
"${PROJECT_SOURCE_DIR}/../sdk/platforms/win/bin/"
$<TARGET_FILE_DIR:main>)
endif()
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy
"${PROJECT_SOURCE_DIR}/../sdk/DBR-PresetTemplates.json"
$<TARGET_FILE_DIR:main>/DBR-PresetTemplates.json)
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
COMMAND ${CMAKE_COMMAND} -E copy
"${PROJECT_SOURCE_DIR}/../sdk/DLR-PresetTemplates.json"
$<TARGET_FILE_DIR:main>/DLR-PresetTemplates.json)
add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
COMMAND ${CMAKE_COMMAND} -E make_directory $<TARGET_FILE_DIR:main>/CharacterModel
COMMAND ${CMAKE_COMMAND} -E copy_directory
"${PROJECT_SOURCE_DIR}/../sdk/CharacterModel"
$<TARGET_FILE_DIR:main>/CharacterModel)
```
## Implementing Barcode Scanning and OCR Text Extraction in C++
To quickly get started with the API, we can refer to the barcode sample code [VideoDecoding.cpp](https://github.com/Dynamsoft/barcode-reader-c-cpp-samples/blob/main/Samples/VideoDecoding/VideoDecoding.cpp) provided by Dynamsoft. The sample code demonstrates how to decode barcodes from video frames using OpenCV. Based on this sample code, we can add OCR text extraction functionality using the Dynamsoft Label Recognizer. Let's take the steps to implement barcode scanning and OCR text extraction in C++.
### Step 1: Include the SDK Header Files
To use the **Dynamsoft Barcode Reader** and **Dynamsoft Label Recognizer** together, we need to include two header files: `DynamsoftCaptureVisionRouter.h` and `DynamsoftUtility.h`, which contain all the necessary classes and functions. The OpenCV header files may vary depending on the version you are using. The following code snippet shows the header files and namespaces used in the sample code:
```cpp
#include "opencv2/core.hpp"
#include "opencv2/imgproc.hpp"
#include "opencv2/highgui.hpp"
#include "opencv2/videoio.hpp"
#include "opencv2/core/utility.hpp"
#include "opencv2/imgcodecs.hpp"
#include <iostream>
#include <vector>
#include <chrono>
#include <iostream>
#include <string>
#include "DynamsoftCaptureVisionRouter.h"
#include "DynamsoftUtility.h"
using namespace std;
using namespace dynamsoft::license;
using namespace dynamsoft::cvr;
using namespace dynamsoft::dlr;
using namespace dynamsoft::dbr;
using namespace dynamsoft::utility;
using namespace dynamsoft::basic_structures;
using namespace cv;
```
### Step 2: Set the License Key
When requesting a trial license key, you can either choose a single product key or a combined key for multiple products. In this example, we need to set a combined license key for activating both SDK modules:
```cpp
int iRet = CLicenseManager::InitLicense("LICENSE-KEY");
```
### Step 3: Create a Class for Buffering Video Frames
The `CImageSourceAdapter` class is used for fetching and buffering image frames. We can create a custom class that inherits from `CImageSourceAdapter`.
```cpp
class MyVideoFetcher : public CImageSourceAdapter
{
public:
MyVideoFetcher(){};
~MyVideoFetcher(){};
bool HasNextImageToFetch() const override
{
return true;
}
void MyAddImageToBuffer(const CImageData *img, bool bClone = true)
{
AddImageToBuffer(img, bClone);
}
};
MyVideoFetcher *fetcher = new MyVideoFetcher();
fetcher->SetMaxImageCount(4);
fetcher->SetBufferOverflowProtectionMode(BOPM_UPDATE);
fetcher->SetColourChannelUsageType(CCUT_AUTO);
```
### Step 4: Image Processing and Result Handling
The `CCaptureVisionRouter` class is the core class for image processing. It provides a built-in thread pool for asynchronously processing images that are fetched by the `CImageSourceAdapter` object.
```cpp
CCaptureVisionRouter *cvr = new CCaptureVisionRouter;
cvr->SetInput(fetcher);
```
To handle the barcode and OCR text results, we need to register a custom class that inherits from `CCapturedResultReceiver` with the `CCaptureVisionRouter` object.
```cpp
class MyCapturedResultReceiver : public CCapturedResultReceiver
{
virtual void OnRecognizedTextLinesReceived(CRecognizedTextLinesResult *pResult) override
{
}
virtual void OnDecodedBarcodesReceived(CDecodedBarcodesResult *pResult) override
{
}
};
CCapturedResultReceiver *capturedReceiver = new MyCapturedResultReceiver;
cvr->AddResultReceiver(capturedReceiver);
```
### Step 5: Stream Video Frames and Feed to the Image Processor
OpenCV provides a simple way to capture video frames from a camera. We can use the `VideoCapture` class to open a camera and fetch frames continuously. In the meantime, we call the `StartCapturing()` and `StopCapturing()` methods of the `CCaptureVisionRouter` object to switch the processing task on and off.
```cpp
string settings = R"(
{
"CaptureVisionTemplates": [
{
"Name": "ReadBarcode&AccompanyText",
"ImageROIProcessingNameArray": [
"roi-read-barcodes-only", "roi-read-text"

]
}
]
})";
VideoCapture capture(0);
bool use_ocr = false;
if (use_ocr)
{
cvr->InitSettings(settings.c_str(), errorMsg, 512);
errorCode = cvr->StartCapturing("ReadBarcode&AccompanyText", false, errorMsg, 512);
}
else
{
errorCode = cvr->StartCapturing(CPresetTemplate::PT_READ_BARCODES, false, errorMsg, 512);
}
int width = (int)capture.get(CAP_PROP_FRAME_WIDTH);
int height = (int)capture.get(CAP_PROP_FRAME_HEIGHT);
for (int i = 1;; ++i)
{
Mat frame;
capture.read(frame);
if (frame.empty())
{
cerr << "ERROR: Can't grab camera frame." << endl;
break;
}
CFileImageTag tag(nullptr, 0, 0);
tag.SetImageId(i);
CImageData data(frame.rows * frame.step.p[0],
frame.data,
width,
height,
frame.step.p[0],
IPF_RGB_888,
0,
&tag);
fetcher->MyAddImageToBuffer(&data);
imshow("1D/2D Barcode Scanner", frame);
int key = waitKey(1);
if (key == 27 /*ESC*/)
break;
}
cvr->StopCapturing(false, true);
```
The image processing tasks support preset templates and custom settings. If we only need to scan 1D and 2D barcodes, we can use the `CPresetTemplate::PT_READ_BARCODES` template. If we want to extract OCR text labels along with barcodes, a highly customized template is required.
### Step 6: Handle the Results and Display
Since the results are returned from a worker thread, to display them on the video frames in the main thread, we create a vector to store them and use a **mutex** to protect the shared resource.
```cpp
struct BarcodeResult
{
std::string type;
std::string value;
std::vector<cv::Point> localizationPoints;
int frameId;
string line;
std::vector<cv::Point> textLinePoints;
};
std::vector<BarcodeResult> barcodeResults;
std::mutex barcodeResultsMutex;
```
Here is the implementation of the `OnRecognizedTextLinesReceived` and `OnDecodedBarcodesReceived` callback functions:
```cpp
virtual void OnRecognizedTextLinesReceived(CRecognizedTextLinesResult *pResult) override
{
std::lock_guard<std::mutex> lock(barcodeResultsMutex);
barcodeResults.clear();
const CFileImageTag *tag = dynamic_cast<const CFileImageTag *>(pResult->GetOriginalImageTag());
if (pResult->GetErrorCode() != EC_OK)
{
cout << "Error: " << pResult->GetErrorString() << endl;
}
else
{
int lCount = pResult->GetItemsCount();
for (int li = 0; li < lCount; ++li)
{
BarcodeResult result;
const CTextLineResultItem *textLine = pResult->GetItem(li);
CPoint *points = textLine->GetLocation().points;
result.line = textLine->GetText();
result.textLinePoints.push_back(cv::Point(points[0][0], points[0][1]));
result.textLinePoints.push_back(cv::Point(points[1][0], points[1][1]));
result.textLinePoints.push_back(cv::Point(points[2][0], points[2][1]));
result.textLinePoints.push_back(cv::Point(points[3][0], points[3][1]));
CBarcodeResultItem *barcodeResultItem = (CBarcodeResultItem *)textLine->GetReferenceItem();
points = barcodeResultItem->GetLocation().points;
result.type = barcodeResultItem->GetFormatString();
result.value = barcodeResultItem->GetText();
result.frameId = tag->GetImageId();
result.localizationPoints.push_back(cv::Point(points[0][0], points[0][1]));
result.localizationPoints.push_back(cv::Point(points[1][0], points[1][1]));
result.localizationPoints.push_back(cv::Point(points[2][0], points[2][1]));
result.localizationPoints.push_back(cv::Point(points[3][0], points[3][1]));
barcodeResults.push_back(result);
}
}
}
virtual void OnDecodedBarcodesReceived(CDecodedBarcodesResult *pResult) override
{
std::lock_guard<std::mutex> lock(barcodeResultsMutex);
if (pResult->GetErrorCode() != EC_OK)
{
cout << "Error: " << pResult->GetErrorString() << endl;
}
else
{
auto tag = pResult->GetOriginalImageTag();
if (tag)
cout << "ImageID:" << tag->GetImageId() << endl;
int count = pResult->GetItemsCount();
barcodeResults.clear();
for (int i = 0; i < count; i++)
{
const CBarcodeResultItem *barcodeResultItem = pResult->GetItem(i);
if (barcodeResultItem != NULL)
{
CPoint *points = barcodeResultItem->GetLocation().points;
BarcodeResult result;
result.type = barcodeResultItem->GetFormatString();
result.value = barcodeResultItem->GetText();
result.frameId = tag->GetImageId();
result.localizationPoints.push_back(cv::Point(points[0][0], points[0][1]));
result.localizationPoints.push_back(cv::Point(points[1][0], points[1][1]));
result.localizationPoints.push_back(cv::Point(points[2][0], points[2][1]));
result.localizationPoints.push_back(cv::Point(points[3][0], points[3][1]));
barcodeResults.push_back(result);
}
}
}
}
```
The following code snippet shows how to draw the barcode and OCR text results on the video frames:
```cpp
{
std::lock_guard<std::mutex> lock(barcodeResultsMutex);
for (const auto &result : barcodeResults)
{
// Draw the bounding box
if (result.localizationPoints.size() == 4)
{
for (size_t i = 0; i < result.localizationPoints.size(); ++i)
{
cv::line(frame, result.localizationPoints[i],
result.localizationPoints[(i + 1) % result.localizationPoints.size()],
cv::Scalar(0, 255, 0), 2);
}
}
// Draw the barcode type and value
if (!result.localizationPoints.empty())
{
cv::putText(frame, result.type + ": " + result.value,
result.localizationPoints[0], cv::FONT_HERSHEY_SIMPLEX,
0.5, cv::Scalar(0, 255, 0), 2);
}
if (!result.line.empty() && !result.textLinePoints.empty())
{
for (size_t i = 0; i < result.textLinePoints.size(); ++i)
{
cv::line(frame, result.textLinePoints[i],
result.textLinePoints[(i + 1) % result.textLinePoints.size()],
cv::Scalar(0, 0, 255), 2);
}
cv::putText(frame, result.line,
result.textLinePoints[0], cv::FONT_HERSHEY_SIMPLEX,
0.5, cv::Scalar(0, 0, 255), 2);
}
}
}
```

## Parts to Prepare
Only the items used in the first part are listed. If you want to buy in bulk, please refer to other articles.
- Breadboard (e.g., [BB-801](https://akizukidenshi.com/catalog/g/g105294/)) x1
- Planning to use a combination of half sizes
- [Pro Micro + Pin Header](https://shop.yushakobo.jp/products/3905) x1
- The Type-C version is less likely to break, so it's more expensive but safer. If you can fix it with a glue gun or have other Pro Micros, those are also fine.
- As mentioned later, there are various types of Pro Micro, so be careful.
- Reset switch x1
- [Yushakobo's 2-pin tactile switch](https://shop.yushakobo.jp/products/a0800ts-01-1) is cheap and convenient, but anything that can be inserted into the breadboard is fine.
- [Jumper wires](https://akizukidenshi.com/catalog/g/g105159/) x many
- You will need a lot as they are used frequently.
- Cable to connect Pro Micro to PC
- It seems that charging-only cables may not be properly recognized.
This is all you need for a simple operation check.
## Rough Terms / Reference Information
- Types of Pro Micro: There are many compatible models. It is important to know which Pro Micro you have and to understand the chip and pin assignments.
- The following article is helpful: [Pro Micro and its Variations - zenn.dev](https://zenn.dev/koron/articles/9fee38469a8acc)
- Pin assignment of Pro Micro: Information on what the pins coming out of the Pro Micro are. You can check which leg of the chip ([ATmega32U4](https://akizukidenshi.com/catalog/g/g109835/)) is coming out from where. This also varies by type, so look at the printing on the board to find the same one. We will proceed with the general one shown below.

## Software to Prepare
- Arduino IDE
- The environment for burning firmware to the Pro Micro. This is convenient.
## Implementation
### 1. Solder the Pro Micro and Pin Header
To insert the Pro Micro into the breadboard, attach the pin header.
You need to consider **which side to face up** and whether the height of the pin header is sufficient (whether cables can be inserted). To make it less likely to break, I am trying to fix it with the cable insertion port facing down. However, generally, it seems to be the opposite, and the circuit diagram will be mirrored, so be careful.
<figure><img src="https://res.cloudinary.com/purucloud/image/upload/v1712903953/wp_assets/promicro_bb.png" alt=""><figcaption>Probably reversed</figcaption></figure>
For soldering, just solder the pins you will use this time. The targets are GNDx3, RST, and VCC. If you need more pins later, solder them as needed. In the next part, we will also use 2 (SDA) and 3 (SCL), so if you want to solder them all at once, do so.
### 2. Wiring on the Breadboard
Place the Pro Micro at the top and wire the necessary pins. As shown below, connect the + and - lanes on the left and right of the breadboard, connect GND and VCC, and connect the switch to #RST (RST with an upper line) and GND to complete. It will be easier later if you make the side with pins 2 and 3 of the Pro Micro wider.
<figure><img src="https://res.cloudinary.com/purucloud/image/upload/v1712903946/wp_assets/bb_1.png" alt=""><figcaption>Pro Micro and Reset Switch</figcaption></figure>
As is common with Reset, the #RST pin is high if left alone and low when resetting. Therefore, it is connected to GND and the switch to run the reset process. This is described in the following Hookup Guide.
[Pro Micro & Fio V3 Hookup Guide - SparkFun Learn - learn.sparkfun.com](https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/troubleshooting-and-faq)
By the way, #RST is internally pulled up, so it will be high if left alone. Internal pull-up is a convenient feature that will appear frequently in the future.

### 3. Burning the Program with Arduino IDE
Launch the Arduino IDE, copy and paste the sample code from the following link, and compile it. It's good because the LED blinks and is easy to understand.
[Pro Micro & Fio V3 Hookup Guide - SparkFun Learn - learn.sparkfun.com](https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/example-1-blinkies)
In the Arduino IDE, you need to select which board to target. You may despair that there is no Pro Micro, but as mentioned in the [previous article](https://zenn.dev/koron/articles/9fee38469a8acc), it is compatible with **Arduino Leonardo**, so select that. Depending on the model, it may not work well, so refer to [this article](https://ht-deko.com/arduino/promicro.html) and select another board to burn.
To burn, double-click the reset switch (single-click for some types of Pro Micro), and the bootloader will start for `< 750ms`, during which you burn it. Press the upload button (Cmd+U) in the Arduino IDE in advance, and it will automatically recognize and burn during the bootloader.
You also need to select the target (Port). If you have never burned a program before, it may not be recognized. The bootloader should be recognized, so reset and see if the list of ports increases. If found, select it quickly and burn it.
If it doesn't work well, first check if the bootloader is recognized. On a Mac, run `ls /dev/tty.*` without the Pro Micro connected. On a MacBook, `/dev/tty.Bluetooth-Incoming-Port` may already be there. On Windows, it may be visible from something like Device Manager (unverified). Next, connect and double-click reset, and check if the display increases with the same command. In my case, it appeared as `/dev/tty.usbmodem12101` (via USB hub). If it doesn't appear, the Pro Micro itself may be defective, or the reset button may not be functioning properly. In the latter case, try shorting #RST and GND on the Pro Micro with tweezers (x2 times) to see if it starts.
### 4. Viewing the Output in Arduino IDE
If you successfully burn it and the Pro Micro starts blinking, you're almost there.
First, check if it appears in `/dev/tty` etc. even in a non-bootloader state. This is to confirm that it is correctly recognized by the PC in normal state. In the case of Arduino Leonardo, it seems that the USB firmware is also burned together when burning from the IDE, allowing good communication with the PC. If not found, you may not have selected the appropriate board to burn. Refer to the previous article and try other boards besides Arduino Leonardo.
If it seems to be connected well, open "Tools" -> "Serial Monitor" and check if you can see a "Hello world!" message. There is a `Serial.println(…)` statement in the program, which can be confirmed from the Arduino IDE. This means you can do print debugging.
If you get a message like "Cannot connect to Serial Monitor," check if you have selected a different port, and try reconnecting and observing.
In this state, you can update the program just by pressing the upload button without entering the bootloader. This is convenient.
## Summary
The initial setup part can be tricky, so if you get it working smoothly up to this point, it's worth celebrating. I also spent a whole day not realizing I needed to select the Arduino Leonardo board.
Next time, we will get into the main topic of I2C.

## A Comprehensive Guide to Reading Glasses Strength Charts
_**
### Introduction
Understanding **_[reading glasses](https://www.efeglasses.com/blog/learning-center/)_** strength charts is essential for anyone who needs reading glasses. These charts provide valuable information about the strength of lenses required to correct presbyopia, a common condition that affects near vision as we age. This guide will help you navigate these charts with ease.
### Understanding Reading Glasses
Reading glasses are non-prescription eyewear designed to correct presbyopia. They are available in various strengths, also known as diopters, which determine how much magnification the lenses provide.
### What is a Diopter?
A diopter is the unit of measurement used to define the refractive power of lenses. The higher the diopter, the stronger the lens. Reading glasses typically range in strength from +1.00 to +4.00 diopters.
### Reading Glass Strength Charts
Reading glass strength charts are tools that help you determine the correct strength of reading glasses you need. They usually include age and the required diopter strength.
### How to Use the Chart
To use a reading glass strength chart, find your age on the chart. The corresponding diopter strength is the suggested starting point for your reading glasses. Remember, this is just a guideline. It's always best to have your eyes examined by a professional to determine the exact strength you need.
### Factors Affecting Reading Glass Strength
```
```
Several factors can affect the strength of reading glasses you need, including:
#### Age
Presbyopia usually begins around the age of 40 and continues to progress with age. As a result, you may find you need to increase the strength of your reading glasses as you get older.
#### Reading Distance
If you tend to hold reading material closer to your eyes, you may need a higher strength. Conversely, if you prefer to hold reading material further away, a lower strength may be sufficient.
#### Eye Health
Certain eye conditions can affect your reading glass strength. Regular eye examinations can ensure you're wearing the correct strength and keeping your eyes healthy.
## Conclusion
Understanding reading glass strength charts can help you find the most suitable pair of reading glasses. However, it's important to remember that these charts are a guideline, and individual needs may vary. Regular eye exams are the best way to ensure you're wearing the correct strength and maintaining optimal eye health.

1,861,416 | Case for explicit error handling | One of the best articles on front-end app architecture I have ever read suggested not-so-popular... | 0 | 2024-05-24T08:06:33 | https://dev.to/senky/case-for-explicit-error-handling-1hcd | frontend, architecture, errors, ux | One of the best articles on front-end app architecture I have ever read suggested not-so-popular patterns, including headless approach (data and logic are strictly separated from UI - e.g. React), explicit initialization (manual dependency injection), or reactivity aversion (no `useEffect`, or MobX's `reaction`). Over the years I have seen the benefits of all the patterns except for one.
It is called _Concentrated error handling_.
The pattern suggests designing code so that error handling doesn't have to be written for each individual call that can fail. It even encourages to treat `catch` clauses as code smell.
My experience just can't seem to find peace with this pattern. Let me give you my biggest concern wight away:
User experience.
<center>🥰</center>
## Why user experience matters the most
You see, we are talking about _front-end_ apps here. They are specifically meant to provide UI to user. They exist _for_ the user. And if you handle your errors in one global error boundary, you compromise user experience. How?
I have been working on a project recently that relied on a single error boundary to do all kinds of stuff we do when our app throws an error:
- log to console
- track to monitoring software
- show error message to user
Can you guess how the error message toast looked like? Yep:
This is wrong on so many levels! User must be able to [read the error message in plain language, understand the problem, and ideally be able to recover from it](https://www.nngroup.com/articles/error-message-guidelines/) (Jakob Nielsen's 9th heuristic rule). But with one (or even multiple) error boundaries you (most of the time) aren't in the right context anymore to be able to provide user with the _least painful experience_.
Let me show you how I envision error handling in front-end apps.
_I am using `fetch` as an example, but this can be anything from websocket connection, browser APIs, library & framework calls, etc._
<center>✨</center>
### Separate severe errors from enhancements
Sometimes data we show aren't strictly needed for the user to perform the task. For example at slido.com's [PowerPoint page](https://www.slido.com/powerpoint-polling), information about version and package size are nice-to-have, but user is still able to download the integration even if endpoint with those information failed. We do not need to show error message to user. Instead, we do nothing - and that's user's _least painful experience_.
You will be surprised how much information is optional once you start paying attention to it. Are you deleting a team in any SaaS app? A list of users of that team is usually a good visual indicator for the admin of how severe the action is. But if that request fails, admin is still able to delete the team - and therefore bombarding him/her with messages about failed request is absolutely not _least painful experience_.
With global error boundary, you don't get enough information easily to decide whether the error comes from enhancement or not. Take this example:
```ts
const init = () => {
const response = await fetch('/api/version-and-size')
...
}
const main = () => {
try {
init()
} catch (error) {
// All info you have here is generic `TypeError ` in `error` variable.
}
}
main()
```
We literally have no idea what endpoint failed. Therefore we cannot decide if response data are enhancement or mandatory information.
Whereas in this slight change:
```ts
const init = () => {
try {
const response = await fetch('/api/version-and-size')
...
} catch (error) {
// Code context gives you hint that this failure is just enhancement.
}
}
const main = () => {
init()
}
main()
```
The code itself gives you enough context to react to error appropriately - that is to ignore it.
<center>🛠️</center>
### React to error in the best manner possible
Now that you purposefully ignored enhancements, let's discuss handling of severe errors.
Imagine social network such as dev.to where blog posts functionality is present. You want to edit a post. Two possible points of failure are:
1. loading current post content into the editor,
2. saving edited content.
Both cases can fail on the same network level giving you exactly the same error, yet handling should be radically different:
1. When post content fails to load, a big error message (maybe replacing whole editor) should ask user to attempt to reload the page or manually re-trigger content fetching.
2. If saving fails, you most definitely don't want to remove the edited content with big error message. Instead, a toast informing about unsuccessful saving asking for a retry later is correct way to do it.
This isn't possible with global error boundary, because, again, you don't have the context (and maybe also access to models/components that need to be updated).
This article doesn't discuss the best patters for error handling, but there is [tons](https://www.nngroup.com/articles/error-message-guidelines/) [of](https://www.smashingmagazine.com/2022/08/error-messages-ux-design/) [materials](https://uxplanet.org/error-message-guidelines-6ce257d3d0bd) [about](https://design4users.com/ux-design-error-screens-and-messages/) [this](https://talebook.io/blog/error-states/) [topic](https://www.pencilandpaper.io/articles/ux-pattern-analysis-error-feedback) on the Internet.
<center>🫂</center>
### Code colocation is your friend
You are probably thinking: hey Jakub, I can write a generic wrapper around fetch that will catch `TypeError`s, add necessary data to it and re-throw it. That way my global error boundary has the context you are talking about.
And you are right, except for one thing. You start rolling your spaghetti if you ever use that additional context for conditional actions:
```ts
const main = (mainController) => {
try {
init()
} catch (error: EnrichedError) {
switch (error.endpoint) {
if (error.endpoint === '/api/version-and-size') {
// just enhancement
return
}
if (error.endpoint.match(/\/posts\/\d+\/edit/)) {
mainController.postEditModel.error = true
return
}
if (error.endpoint === '/edit' && error.method === 'POST') {
mainController.toast('Saving failed. Please try again later.')
return
}
...
}
}
}
main(mainController)
```
This is what I call a code smell! Instead, let's leverage existing (implicit) context and also make sure that related code sits together:
```ts
try {
const response = await fetch('/api/version-and-size')
...
} catch () {
// just enhancement
}
...
try {
const response = await fetch(`/posts/${postId}/edit`)
...
} catch () {
model.error = true // notice we don't access `mainController` anymore because we are in the context of `postEditModel`
}
...
try {
const response = await fetch(`/edit`, { method: 'POST', body: JSON.stringify(data), ... })
...
} catch () {
mainController.UIController.toast('Saving failed. Please try again later.')
}
```
<center>🌐</center>
### On global error boundaries
Are global error boundaries any good then? I think so! They excel at tasks that you want to perform for every error out there: logging to console, tracking to your favorite monitoring tool, or even as a fallback for all the errors that aren't explicitly handled (although I'd say log those cases just so that you can add explicit handling later).
Also, top-level error handler is important for the user, because it serves as a last resort for catching unhandled errors and displaying meaningful error page to the user.
With this in mind you can _sometimes_ purposefully handle errors implicitly. For example if app initialization relies on a request and app cannot be initialized without it, you can ignore try/catch block there and let global error handler display unrecoverable error page to the user.
## Conclusion
Global error handling compromises user experience. Handle errors explicitly to leverage its implicit context. It will help you choose the best reaction to error to optimize for _least painful experience_ for your user. Use global error handler to catch and track yet unhandled errors. Remember: you make front-end apps, user comes first.

1,863,665 | Exploring TypeScript Generics: Enhancing Type Safety and Reusability | TypeScript, a superset of JavaScript, offers developers the ability to write statically typed code... | 0 | 2024-05-24T08:02:12 | https://dev.to/that_mallu_dev/exploring-typescript-generics-enhancing-type-safety-and-reusability-20ac | javascript, beginners, typescript, webdev | TypeScript, a superset of JavaScript, offers developers the ability to write statically typed code while enjoying the flexibility and expressiveness of JavaScript. Among its many features, TypeScript generics stand out as a powerful tool for creating reusable and type-safe code.
## Understanding Generics
Generics in TypeScript allow us to create functions, classes, and interfaces that can work with a variety of data types while maintaining type safety at compile time. This means we can write code that is more flexible and less prone to runtime errors.
## Basic Syntax
Let's start with a basic example of a generic function:
```
function greet<T>(arg: T): T {
return arg;
}
// Usage
let result = greet<string>("Hello");
// result is of type string
```
In this example, the function 'greet' takes a type parameter 'T', which represents the type of the argument passed to the function. The function then returns the argument of the same type 'T'.
## Benefits of Generics
One of the key benefits of generics is code reusability. With generics, we can write functions and classes that can operate on different types without sacrificing type safety. This reduces code duplication and makes our codebase more maintainable.
Consider the following example of a generic class:
```
class Box<T> {
value: T;
constructor(value: T) {
this.value = value;
}
}
// Usage
let box1 = new Box<number>(42);
let box2 = new Box<string>("hello");
```
Here, the 'Box' class can hold values of any type 'T'. We specify the type when creating instances of 'Box', ensuring type safety.
## Common Use Cases
Generics are particularly useful when working with collections and higher-order functions. For example, let's create a generic utility function to find the first occurrence of an element in an array:
```
function findFirstItem<T>(arr: T[], predicate: (item: T) => boolean): T | undefined {
for (let item of arr) {
if (predicate(item)) {
return item;
}
}
return undefined;
}
// Usage
let numbers: number[] = [1, 2, 3, 4, 5];
let result = findFirstItem(numbers, n => n > 3); // Returns 4
console.log(result); // Output: 4
let strings: string[] = ["apple", "banana", "cherry"];
let stringResult = findFirstItem(strings, s => s.startsWith("b")); // Returns "banana"
console.log(stringResult); // Output: banana
```
## Advanced Generics
At their core, advanced generics in TypeScript provide sophisticated ways to define types that are more flexible and precise. They enable us to express complex relationships between types, create type guards, and build highly reusable components.
### Conditional Types
Conditional types allow us to define types that depend on a condition. This feature enables us to create powerful type transformations and mappings. Here's a simple example:
```
type IsArray<T> = T extends Array<any> ? true : false;
// Usage
type Result = IsArray<number[]>; // Result is true
```
In this example, the IsArray type checks whether the provided type 'T' is an array.
###Mapped Types
Mapped types transform the properties of one type into another type. They are particularly useful for creating new types based on existing ones. Consider the following example:
```
type Optional<T> = {
[K in keyof T]?: T[K];
};
// Usage
interface User {
name: string;
age: number;
}
type OptionalUser = Optional<User>;
// OptionalUser is { name?: string; age?: number; }
```
Here, the Optional mapped type converts all properties of 'T' into optional properties.
### Type Constraints
Type constraints allow us to restrict the types that can be used with generics. This is especially useful when working with complex types or ensuring certain properties exist. Here's an example:
```
function getProperty<T, K extends keyof T>(obj: T, key: K): T[K] {
return obj[key];
}
// Usage
const user = { name: 'Alice', age: 30 };
const name = getProperty(user, 'name'); // Type of name is string
```
In this example, 'K extends keyof T' ensures that the key parameter is a valid property of the obj parameter.
## Best Practices
When using generics, it's important to follow some best practices. Use descriptive names for type parameters to improve code readability. Additionally, consider using constraints to enforce specific requirements on type parameters.

1,863,672 | Guidelines for Structuring tables in technical writing for GenAI-based agents | Representation of complex information can be done effectively through text in the form of tables.... | 0 | 2024-05-24T08:01:22 | https://dev.to/ragavi_document360/guidelines-for-structuring-tables-in-technical-writing-for-genai-based-agents-58k4 | Representation of complex information can be done effectively through text in the form of tables. With a simple yet powerful design, tables offer an elegant solution to distill vast amounts of data into a visually captivating format. Technical writers rely on tables to decipher key points, discern trends, and unveil relationships, empowering them to craft comprehensive documents. In the realm of technical writing, tables have become indispensable tools, revolutionizing the content creation process.
## Overview of Table formats
Tables, composed of rows and columns, organize content with clarity. They effortlessly transform into multi-dimensional hierarchies, encapsulating vast amounts of data. From the fundamental table of contents to intricate indexes, tables summarize knowledge with clarity. Technical writers adapt tables to suit content types and user experience needs, favoring column tables for mobile interfaces and row tables for desktops.
## Large Language Model Challenges
LLMs, trained on vast internet text, excel with unstructured data but face hurdles with tables. These structured formats challenge their processing capabilities, especially with numerical data. This complexity risks overshadowing vital details, hindering decision-making. Technical writers' preference for tabular data clashes with LLM limitations, impacting response generation. Refactoring tables becomes crucial for LLMs to grasp structured information effectively.
## Refactoring tables for LLMs
The tables inside your knowledge base content need to be refactored to make it suitable for ingestion by business applications powered by Large Language Models (LLMs). The following are some of the best practices to be followed while refactoring the table
- Do not use symbols inside the table content as they are removed during pre-processing steps
- Do not have null values / empty spaces inside your table content as GenAI-based agents might hallucinate while trying to use those data!
- Ensure that tables have header information along with proper rows
- If you wish to have some binary information part of the table content, use Yes/No, True/ False, or any other option. Ensure that this information is covered in the system message of your RAG (Retrieval Augmented Generation) tool
- The table should be complete such that all cells have values in them
- Use < abbr > tag to define abbreviations of terms inside the table content
- Use < abbr > tag to describe tick mark and cross mark so that LLMs can understand the meaning of symbols inside the table content
- Table cell values can be a mix of numeric values and text. However, it is recommended to have one type of data present inside those table cells

1,856,206 | Best Practices for Managing the Security Risks Associated with Open-Source Software in 2024 | This post originally appeared on my blog Welcome to this four-part mini-series on open-source best... | 27,386 | 2024-05-24T08:00:00 | https://forward.digital/blog/best-practices-for-managing-the-security-risks-associated-with-open-source-software | webdev, opensource, productivity, learning | [_This post originally appeared on my blog_](https://forward.digital/blog/best-practices-for-managing-the-security-risks-associated-with-open-source-software)
Welcome to this four-part mini-series on open-source best practices. In this series, we will discuss the best practices for adopting open-source software (OSS) into your organisation, managing OSS dependencies daily, fostering collaboration with the OSS community, and finally, my opinion on which best practices are best adopted for organisations of all sizes and industries.
This article will discuss the best practices for managing open-source software, including the internal considerations organisations must make, the metrics to judge the quality of OSS components, the approval process, and the licensing of OSS components.
Open source software (OSS) is a critical component of modern software development. It allows developers to leverage existing code, reduce development time, and focus on building new features.
However, OSS also introduces security risks. Vulnerabilities in OSS components can expose organisations to cyber threats, data breaches, and financial losses. To mitigate these risks, organisations must adopt best practices for managing the security risks associated with OSS.
In this blog post, we explore best practices for managing the security risks associated with OSS.
We review the literature, conduct interviews with industry experts, and analyse case studies to identify key strategies for securing OSS components. Our research highlights the importance of regular vulnerability assessments, tooling, continuous monitoring, binary repositories, risk management and mitigation, static application security testing, and forking as essential practices for managing the security risks associated with OSS.
## Regular vulnerability assessments
Regular vulnerability assessments identify, prioritise, and apply patches to systems and software to address vulnerabilities. As the OSS landscape constantly evolves, organisations encounter thousands of new vulnerabilities. Yet, many businesses do not have a robust patch management strategy in place and fail to implement critical patches promptly, leaving them vulnerable to security breaches ([Hackerone, 2024](https://www.hackerone.com/knowledge-center/what-vulnerability-assessment-benefits-tools-and-process)).
With an estimated 84% of open source components having at least one vulnerability ([Sawers, 2021](https://venturebeat.com/2021/04/13/synopsys-84-of-codebases-contain-an-open-source-vulnerability/)), regular vulnerability assessments are essential for managing the security risks associated with OSS.
A rough overview of the process is as follows ([Hackerone, 2024](https://www.hackerone.com/knowledge-center/what-vulnerability-assessment-benefits-tools-and-process)):
1. **Initial Preparation** – Defining the scope and goals of the vulnerability testing to ensure a targeted and practical assessment.
2. **Vulnerability Testing** – Running automated tests to identify vulnerabilities within the systems included in the predefined scope.
3. **Prioritise Vulnerabilities** – Assessing which vulnerabilities are most critical, requiring immediate attention, and evaluating their potential business impact.
4. **Create Vulnerability Assessment Report** – Produce a detailed report outlining medium and high-priority vulnerabilities found and recommended remediation strategies.
5. **Continuous Vulnerability Assessment** – Conducting scans for vulnerabilities on a continuous basis to verify if previous vulnerabilities have been effectively remediated and to discover new ones.
Regular vulnerability assessments are frequently mentioned in the best practices for managing the security risks associated with OSS. Without automated vulnerability assessments, it is difficult to keep up with the large number of OSS components used in modern software systems and the many vulnerabilities discovered each year. Therefore, with automation, regular vulnerability assessments are a best practice for managing the security risks associated with OSS.
## Tooling
Tooling is the functionality that allows for automating the management of OSS components. It can be very useful as a way to manage the large number of OSS components used in modern software systems without introducing unnecessary manual work. Any software project that actively works to reduce security vulnerabilities is less risky. Therefore, tools that aid in identifying security vulnerabilities within software projects are critical ([Department of Defense, 2022](https://dodcio.defense.gov/Portals/0/Documents/Library/SoftwareDev-OpenSource.pdf)).
There are three tools found from our literature review that are considered “leaders”; Snyk, Sonatype, and Synopsys (Black Duck) ([Worthington et al., 2023](https://www.forrester.com/report/the-forrester-wave-tm-software-composition-analysis-q2-2023/RES178483)). These tools are designed to help organisations manage the security risks associated with OSS. They can be used to automate vulnerability assessments, manage licensing, enforce an OSS policy, and generate SBOMs. With this in mind, due to the diversity of OSS components, there is no one-size-fits-all solution ([Wen et al., 2019](https://ieeexplore.ieee.org/document/9073010)).
We consider tooling to be a best practice for managing the security risks associated with OSS. It enables organisations of all sizes to manage many OSS components used in modern software systems without introducing unnecessary manual work. There is a lot of research into tooling, and a wide range of tools are available. We found that many tool-promoting papers and articles are written by the companies that produce the tools, so it is down to the organisation to evaluate the tools and decide which one is best for them.
## Continuous monitoring
Modern software applications are built using a complex web of dependencies, including open-source libraries and frameworks. This process is typically recursive, with each dependency having its dependencies, and so on ([Dietrich et al., 2023](https://arxiv.org/pdf/2306.05534.pdf)). Infamously, this web of dependencies can lead to security vulnerabilities, as seen in the equifax data breach ([Fruhlinger, 2020](https://www.csoonline.com/article/567833/equifax-data-breach-faq-what-happened-who-was-affected-what-was-the-impact.html)) and the log4j vulnerability ([Gallo, 2022](https://builtin.com/cybersecurity/log4j-vulerability-explained)).
Continuous monitoring is the process of monitoring OSS components for vulnerabilities and other security risks on an ongoing basis. These can be manual but are often automated and part of an organisation’s CI/CD pipeline. It is crucial for application developers to detect dependencies on vulnerable libraries as soon as possible, to assess their impact precisely, and to mitigate any potential risk ([Ponta et al., 2020](https://dl.acm.org/doi/10.1007/s10664-020-09830-x)).
Now more than ever, developers are using automation to secure their dependencies; in 2023, developers merged 60% more pull requests from GitHub’s Dependabot, a tool that automates dependency updates, than in 2022 ([Daigle, 2023](https://github.blog/2023-11-08-the-state-of-open-source-and-ai/)).
Software composition analysis (SCA) can be used to conduct regular vulnerability assessments, can be implemented as part of the continuous integration/continuous deployment (CI/CD) pipeline, and can be used to enforce an OSS policy ([Alvarenga, 2023a](https://www.crowdstrike.com/cybersecurity-101/secops/software-bill-of-materials-sbom/)). SCAs will provide an inventory of all open-source components used in a project, including their versions and licenses, and will also identify any known vulnerabilities in these components; effectively, producing an SBOM ([Alvarenga, 2023a](https://www.crowdstrike.com/cybersecurity-101/secops/software-bill-of-materials-sbom/)).
Due to the dynamic nature of the open-source ecosystem, continuous monitoring is essential for managing the security risks associated with OSS. An SCA is a great way to monitor OSS components continuously and can be implemented as part of the CI/CD pipeline and can be used to enforce an OSS policy. It is a best practice for managing the security risks associated with OSS.
## Binary repositories
A binary repository manager is a tool designed to store and manage binary files (the compiled version of your source code) and their metadata. Some popular binary repository managers include JFrog Artifactory, Sonatype Nexus Repository, and GitHub Packages.
A binary repository manager is indispensable for managing open-source components effectively. It facilitates the caching of local copies of these elements, ensuring that frequently used packages remain accessible even during downtimes of external repositories. This capability is essential for maintaining continuous project development and operations without interruptions.
Moreover, such a tool distinguishes between approved third-party artefacts and those pending approval, significantly improving the management and visibility of open-source components within projects. It also allows access to specific libraries to be excluded and limited, thereby safeguarding projects from incorporating non-compliant artefacts ([Wainstein, 2018](https://www.altexsoft.com/blog/5-best-practices-for-managing-open-source-components/)).
By caching versions of all open-source software components, you also safeguard against incidents like the left-pad debacle, where the withdrawal of a minor package from the npm package manager (a package manager for the JavaScript programming language) resulted in widespread failure in numerous projects ([Williams, 2016](https://www.theregister.com/2016/03/23/npm_left_pad_chaos/)).
There is a licensing concern, specifically with GPL-licensed open-source software. The GPL license requires that any software distributed that includes or is derived from GPL-licensed code must itself be available under the GPL. If a binary repository contains GPL software and is shared externally, the entire repository may need to be open-sourced. For example, Microsoft released Hyper-V drivers with GPL-licensed binaries, leading to Microsoft having to open-source the drivers in question ([Linux Network Plumber, 2009](https://linux-network-plumber.blogspot.com/2009/07/congratulations-microsoft.html)).
Binary repositories appear to be a polarising issue in the literature. The [Department of Defense, 2022](https://dodcio.defense.gov/Portals/0/Documents/Library/SoftwareDev-OpenSource.pdf) recommended binary repositories as a best practice for managing the security risks associated with OSS, whereas [Anand, 2023](https://security.salesforce.com/blog/seven-best-practices-to-secure-your-open-source-components) (Salesforce) mentioned securing a repository as a best practice, but didn’t mention binary repositories specifically.
## Risk management and mitigation
Risk management and mitigation is the process of identifying, assessing, and prioritising risks, and then taking steps to reduce or eliminate them.
According to the Open Worldwide Application Security Project (OWASP), the most significant risk associated with open source software is “Vulnerable and Outdated Components” and has moved from 9th to the 6th most critical risk to web applications ([OWASP, 2020](https://owasp.org/www-project-top-ten/)).
OSS vulnerabilities grew by 50% year-on-year — from just over 4,000 in 2018 to over 6,000 in 2019 ([Zorz, 2020](https://www.helpnetsecurity.com/2020/03/13/open-source-vulnerabilities-2019/)).
One reason for the increase in vulnerabilities is the growing number of open source components being used in software projects from developers utilising the speed and convenience of open source, especially under time pressure, without considering the security implications. This highlights the need for formal processes to manage the risks. Typically, these correlated to implementing some continuous monitoring and regular vulnerability assessments, as outlined in Section 4.2.1 and 4.2.3 ([Anand, 2023](https://security.salesforce.com/blog/seven-best-practices-to-secure-your-open-source-components), [Chandler et al., 2022](https://www.mayerbrown.com/en/insights/publications/2022/10/the-importance-of-tracking-and-managing-the-use-of-open-source-software}), [Mathpati, 2023](https://cobalt.io/blog/risks-of-open-source-software)). Such efforts should avoid being overly laborious and manual to ensure they do not frustrate developers and slow down the development process ([Contrast Security, 2020](https://www.contrastsecurity.com/hubfs/Understanding-the-Risks_WhitePaper_042020_Final.pdf?hsLang=en)).
Like those outlined in this report, the most effective way to mitigate OSS risks is to follow best practices ([Chandler et al., 2022](https://www.mayerbrown.com/en/insights/publications/2022/10/the-importance-of-tracking-and-managing-the-use-of-open-source-software})).
Interestingly, our interviews and case studies found that the approach to risk and risk mitigation varied from organisation to organisation. Larger organisations seemed more proactive in mitigating risk, with dedicated teams and processes in place. Whereas smaller organisations were more reactive, only taking action when a risk materialised and looking to improve their processes after the event. This suggests there is a gap in the best practices landscape, as it doesn’t consider the different approaches to risk management and mitigation based on the size of the organisation.
## Static application security testing
Static application security testing (SAST) is a method of testing the security of an application by examining its source code, byte code, or binary code for security vulnerabilities.
Frequent scanning and security assessment of your repository aids in detecting security concerns at early stages, minimising the chance of significant security problems developing later on. Static code analysis tools can pinpoint typical security weaknesses, and dependency vulnerability scanners can highlight any recognised problems in your project’s dependencies ([Anand, 2023](https://security.salesforce.com/blog/seven-best-practices-to-secure-your-open-source-components)). SAST goes hand in hand with the continuous monitoring of OSS components, as it allows for detecting vulnerabilities in OSS components as soon as possible, allowing for their impact to be assessed and mitigated, see Section 4.2.3.
From our research, SAST is only suggested by Salesforce as a best practice. However, current tooling is comprehensive and can be used to automate the continuous monitoring of OSS components, as outlined in Section 4.2.2. Therefore, SAST can be considered a technical implementation of continuous monitoring.
## Forking
Forking is the process of creating a new project based on an existing project. It allows you to monitor alterations in open-source components, as there will always be a connection to the original repository. One of the key advantages mentioned in the definition of open-source is the explicit permission granted to duplicate and independently alter the source code of an open-source project as desired ([The Open Source Definition 2024](https://opensource.org/osd)).
However, it’s important to be mindful that opting to create a private fork entails the responsibility of integrating any updates from the upstream version of the component. This responsibility grows as the differences between the forked components and the original increase. An ideal situation for forking is when you take an open-source component from a project that is unlikely to receive many updates in the future ([Wainstein, 2018](https://www.altexsoft.com/blog/5-best-practices-for-managing-open-source-components/)).
The process often includes creating a distinct OSS developer community (OSS-DC) for the forked version, allowing the organisation to focus on modifying or enhancing specific components of the software—usually those deemed critical for their purposes ([Méndez-Tapia et al., 2021](https://www.scitepress.org/Papers/2021/104970/104970.pdf)).
Forking does get mentioned in varying mediums as a best practice. However, the added responsibility of integrating updates from the upstream version of the component is often overlooked, and from our interviews, we found that forking is not widely used in practice.
## Conclusion
In this blog post, we explored best practices for managing the security risks associated with open-source software. We reviewed the literature, conducted interviews with industry experts, and analysed case studies to identify key strategies for securing OSS components.
Our research highlights the importance of regular vulnerability assessments, tooling, continuous monitoring, binary repositories, risk management and mitigation, static application security testing, and forking as essential practices for managing the security risks associated with OSS.
By adopting these best practices, organisations can reduce the likelihood of security breaches, data loss, and financial losses associated with OSS vulnerabilities. We recommend that organisations implement these practices to enhance the security of their software systems and protect their data and assets.

This new iteration of the web aims to address the limitations and challenges of Web2, focusing on data privacy, security, and user control.
Decentralization at Its Core
Web3 leverages blockchain technology to create a decentralized web, where data is stored across a distributed network of computers rather than on centralized servers. This shift enhances security and reduces the risk of data breaches, as there is no single point of failure.
Decentralization also means that users have more control over their data. Instead of relying on tech giants to manage their personal information, individuals can store and manage their data through decentralized applications (dApps). This empowerment of users is a significant step towards a more secure and private internet.
Enhanced Security and Privacy
One of the key benefits of Web3 is the enhanced security it offers. By utilizing blockchain technology, data is encrypted and stored in a tamper-proof manner. This ensures that information cannot be altered or deleted without the consensus of the network, making it highly secure.
Privacy is another critical aspect of Web3. In the current Web2 environment, users often have to sacrifice their privacy for convenience. Web3 changes this by allowing users to control their digital identities and share only the information they choose. This approach not only protects user privacy but also reduces the chances of identity theft and other cybercrimes.
Smart Contracts and dApps
Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They run on blockchain networks and automatically enforce the terms of the contract when certain conditions are met. This innovation eliminates the need for intermediaries, reducing costs and increasing efficiency.
Decentralized applications, or dApps, are built on blockchain platforms and operate without a central authority. These applications range from financial services and gaming to social media and supply chain management. By removing intermediaries, dApps provide more transparency, lower costs, and improved security.
The Future of Web3
The potential of Web3 is immense, with its applications extending far beyond the current use cases. As more industries adopt blockchain technology, we can expect to see significant changes in how we conduct business, interact socially, and manage data.
Web3 represents a paradigm shift in how we view and use the internet. By prioritizing decentralization, security, and user control, it promises to create a more equitable and secure digital landscape. As technology continues to evolve, Web3 is poised to become the foundation of the next generation of the internet. | klimd1389 |

Using IP search for improved audience targeting is a potent technique for accomplishing this. Through an understanding of **[IP look up](https://ipinfo.info/)** and its marketing applications, companies may successfully customize their campaigns to target the appropriate audience.
**Understanding IP Lookup**
**_Definition_**
IP lookup is the process of determining the geographical location and other relevant information associated with an IP address. It provides insights into the user's location, internet service provider (ISP), and more.
**How it Works**
IP lookup utilizes databases that map IP addresses to geographical locations. When a user visits a website or interacts with online content, their IP address is logged, allowing businesses to identify their location and tailor their marketing efforts accordingly.
**Applications in Marketing**
_**Targeted Advertising**_
By leveraging IP lookup data, businesses can deliver targeted advertisements based on the user's geographical location. This allows for more relevant and personalized marketing messages, increasing the likelihood of engagement and conversion.
**Geotargeting Campaigns**
Geotargeting involves delivering content or promotions to users in specific geographic regions. With IP lookup, businesses can create geotargeted campaigns tailored to the preferences and needs of users in different locations.
**Localized Content**
Understanding the geographical location of users through IP lookup enables businesses to create localized content that resonates with their audience. This could include language-specific content, regional promotions, or references to local events.
**Maximizing ROI with IP Lookup**
**_Improved Relevance_**
By delivering targeted and localized content to users, businesses can improve the relevance of their marketing efforts. This increases engagement and conversion rates, ultimately leading to a higher ROI on marketing spend.
**Enhanced Customer Experience**
Personalized marketing messages based on geographical location enhance the overall customer experience. Users are more likely to respond positively to content that is relevant to their location and interests, leading to increased brand loyalty and customer satisfaction.
**Optimized Ad Spend**

We don't talk that much, but yes, we talk a lot to computers, and that's what we're supposed to do. I feel so bad for Gen Z kids. They got nothing to learn. I'm blessed to have been born in a time where I had the chance to learn a lot. And by a lot, I mean a lot.
You know, my life is kinda like Mr. Robot. I have so many visions, but I don't do drugs; it's just the side effects of thinking too much. Sometimes, I don't know what is real and what is delusion. Yo, I've got so many interesting things to tell you about. It's our world. It's totally accessible by a select group of people who are playing god roles without asking. They are always watching you. They preset some keywords, and if you hit that word, you're on their watch list.
I don't get it—why do they have Chinese servers in a simple rice cooker? They are planning something big, bigger than you can imagine. The AI you can't even fathom was developed many years ago. But they are only revealing it now. AI is far more dangerous than you think. It's like a devil in the computers.
I will reveal some deadly things about what's going with our technology very soon.
Stay vigilant.

1,863,668 | How To Not Be Replaced By AI As A Software Engineer | Rumors about AI replacing developers have been circulating for the past 2 years. Since the launch of... | 0 | 2024-05-24T07:43:19 | https://sotergreco.com/how-to-not-be-replaced-by-ai-as-a-software-engineer | ai, webdev | Rumors about AI replacing developers have been circulating for the past 2 years. Since the launch of Chat-GPT 3.5, many of you have thought at least once, "What if AI indeed replaced me?"
Well, this is what we are going to discuss; a controversial topic with answers ranging from "No way, AI will never replace developers" to "We only have a couple of years left."
## Where we are now
We've seen some disappointing launches like Devin, which is a really bad attempt to replace developers, but we also have Chat-GPT4, which is really good with programming questions.
So let's ask this question: "*What percentage of your code is written or generated by AI?*". For me, the answer is impressive. In my day-to-day life, I barely write code anymore. GitHub Copilot generates 60-70% with autocomplete, and Grok generates another 10%.
So hold on, you mean you write only 20% of your code? Well, actually yes. If we are not talking about the frontend, which is subjective and AI cannot really generate something good, on the backend, where most apps are basically the same, CRUD is 70% of the backend code, and it is being generated by AI.
## Can We Get More With Current Technology
Talking about the backend, which is actual programming and not the frontend (which I have started to dislike lately), with current technology, we can reach a point where Copilot generates entire workflows.
With prompts like: "*Generate 2 models one for users and one for articles the user will have these fields \[columns\] and this relationships \[relationships\] with articles and also generate the CRUD for this. Don't forget to not put the logic in the controller but in the services*"
Copilot X in the future will do that and they are already working on features like that. Of course the code might not be 100% there but it gives you a boilerplate to work with.
## Endangered Developers
AI will replace many labor jobs. Junior Developers are labor jobs. Junior Devs don't know about system design or problem-solving. They just exist to do the labor and basically the things that Senior Devs are bored of doing because it is a waste of time.
Senior Engineers discuss with managers, conclude software designs, and instruct juniors on what to do. Well, the people who need instructions will be replaced. Because giving instructions is what Seniors do, and if they can give instructions to an AI model, why pay a junior?
Basically, AI is a Senior Developer with no System Design knowledge and human logic.
## You Are A Robot
Ask yourself one question to find out if you will be replaced by AI: How many instructions do I get daily?
If the answer is a lot, then you are most likely that you not going to exist in the realm of programming and work in general in the next few years. If you don't know what to do and need instructions rather than giving guidance to someone else or even guiding yourself, then my friend, you are in big trouble.
Most people are already robots or a version a AI themselves. So then why not a manager or a CEO not replace you with someone that has basically no human rights because its a computer program and needs to breaks or salary.
## Solution
To avoid being replaced by AI, you need to emphasize skills that AI currently lacks. Focus on improving your problem-solving abilities, system design knowledge, and understanding of human logic.
Take on more responsibilities that require critical thinking, creativity, and strategic decision-making.
Continuously learn and adapt to new technologies and methodologies. By becoming more than just a programmer, you can secure your place in the industry.
## Final Words
In conclusion, while AI is advancing rapidly and taking over many routine coding tasks, it is not yet capable of replacing the nuanced and critical thinking skills that senior developers provide.
To stay relevant in the industry, focus on honing your problem-solving abilities, system design expertise, and strategic decision-making. Continuously adapt and learn new technologies to ensure that you remain indispensable in a landscape increasingly influenced by AI.
By becoming less than a coder and more of a problem solver you have nothing to worry about.

1,863,667 | FMZ Mobile APP Trading Terminal, empowering your quantitative trading experience | In the field of quantitative trading, simple and easy-to-use quantitative trading tools have always... | 0 | 2024-05-24T07:42:55 | https://dev.to/fmzquant/fmz-mobile-app-trading-terminal-empowering-your-quantitative-trading-experience-52hh | trading, fmzquant, terminal, cryptocurrency | In the field of quantitative trading, simple and easy-to-use quantitative trading tools have always been one of the keys to achieving wealth growth and risk management. However, with increasing market competition, traditional trading tools are no longer sufficient to meet rapidly changing market demands. To maintain a competitive edge for quantitative traders in the constantly evolving digital asset world, FMZ Mobile App has added a significant new feature: Trading Terminal. This feature will not only improve your trading efficiency, but also empower you through custom plugin programs to assist in trading, injecting new vitality into your trading career.
## Beginner's Guide to Trading Terminal:
### What is the FMZ Mobile APP Trading Terminal?
On the FMZ Quant Trading Platform, you can download the FMZ Quant Mobile APP from the [Mobile App download page](https://www.fmz.com/mobile). After downloading and installing, open the FMZ mobile app and log in with your FMZ account.
Please note that FMZ Quant is divided into FMZ.COM international site and FMZ.CN China domestic site (supporting different markets). When logging in, you need to choose the corresponding site. Accounts for different sites are independent and not interchangeable.
The FMZ Quantitative Trading Platform mobile APP trading terminal is a quantitative trading tool that encapsulates APIs from major exchanges. It allows quick switching between various exchanges, and with the help of various features of the FMZ platform, it can perform data capture analysis, real-time data monitoring, program-assisted trading, semi-automatic/manual trading operations etc.
### How to access and enable the trading terminal function?
After logging into the FMZ Quant Mobile APP, you can see the "Trading Terminal" function on the main interface. Click to enter the trading terminal interface.
Before FMZ launched its mobile APP trading terminal, FMZ's web version had already launched this feature quite early. Whether it is a web-based trading terminal or a mobile APP-based one, **at least one docker program must be deployed**.
This is because all actual requests sent to exchanges are executed from the docker, not on the mobile app, which is safer. It also avoids disadvantages such as API KEY binding IP addresses and inability to use when mobile IP changes.
### Detailed Explanation of Trading Terminal Interface
**1. Main Interface of the Trading Terminal:**
After opening the trading terminal, you can see the main interface of the trading terminal. Clicking on the area in red frame will open up "Docker", "Exchange", and "Markets" configuration interfaces.
- Docker: All docker programs deployed under your current FMZ account will be listed here for selection.
- Exchange: The exchange objects (configured with API KEY information etc.) created in your current FMZ account will also appear in corresponding lists for specific operation selections.
- Markets: Set up the trading pair or contract that this trading terminal is going to operate. The input box widget for trading pairs will display selectable trading pairs/contracts based on entered information.
**2. Trading Zone:**
The Trading Zone displays market depth data;
Trading widgets can be set with order price, order quantity, order direction, leverage and other settings.
The bottom tabs of the main interface display information such as "Orders", "Assets", making your funds, and orders clear at a glance.
**3. K-line Chart:**
If you wish to view the K-line chart while placing an order, a thoughtful design has been implemented here - a collapsible display widget that unfolds the mini K-line chart of the current product.
If you wish to view the K-line chart in a larger area, display market transaction records, depth information and more, you can click on this K-line icon to jump to the professional K-line chart page.
The professional K-line chart interface:
The professional K-line chart interface can also be displayed in landscape mode:
### Trading Plugin
What can a trading terminal plugin do?
- Real-time market data calculation and display.
- Order placement and order management.
- Implement risk management.
- Semi-automatic auxiliary trading strategies.
Which programming languages and tools are used to develop plugins?
- python
- javascript
- c++
What can you get?
- Share your plugin with the community for mutual learning with developers.
- Learn from other developers and get inspired.
- Interact with other quantitative trading enthusiasts.
### Give an Example Based on a Real-life Application Scenario:
In the FMZ community, a user has put forward such a request:
> Use js to traverse all U contract currencies of the Binance exchange, and open a position of 10u (long) for each currency. How is this code written?
This requirement scenario can be implemented with trading terminal plugins actually, and running plugin strategies on the trading terminal is free of charge. Compared to long-term live trading strategies, using trading terminal plugins as an aid is undoubtedly a good choice.
Let's see how to design and implement the user's request.
Firstly, we need to create a trading terminal plugin and add three parameters to its strategy:
Then start writing the plugin program:
```
function main() {
let exName = exchange.GetName()
if (exName != "Futures_Binance") {
return "not support!"
}
let apiBase = "https://fapi.binance.com"
if (isSimulate) {
apiBase = "https://testnet.binancefuture.com"
Log("Switch base address:", apiBase)
}
exchange.SetBase(apiBase)
try {
var obj = JSON.parse(HttpQuery(apiBase + "/fapi/v1/exchangeInfo"))
} catch (e) {
Log(e)
}
let pairs = []
for (var i in obj.symbols) {
if (obj.symbols[i]["status"] !== "TRADING" || obj.symbols[i]["quoteAsset"] !== "USDT") {
continue
}
let = pair = obj.symbols[i]["baseAsset"] + "_" + obj.symbols[i]["quoteAsset"]
pairs.push(pair)
}
let markets = _C(exchange.GetMarkets)
for (var i in pairs) {
// /*
// For testing purposes, only 10 varieties are opened here. If all varieties are needed, this comment content can be deleted.
if (i >= 9) {
break
}
// */
let pair = pairs[i]
exchange.SetCurrency(pair)
exchange.SetContractType("swap")
let ticker = exchange.GetTicker()
if (!ticker) {
continue
}
let = amountPrecision = markets[pair + ".swap"]["AmountPrecision"]
exchange.SetDirection("buy")
let amount = _N(qty / ticker.Last, amountPrecision)
if (amount > 0) {
exchange.Buy(-1, amount)
}
Sleep(100)
}
// Obtain all positions
let pos = exchange.IO("api", "GET", "/fapi/v2/positionRisk")
if (!pos) {
return
}
// View positions
return pos.filter(item => Number(item.positionAmt) != 0)
}
```
After the trading terminal plugin is written, it can be tested:
In the trading terminal of the mobile APP, click on the '...' button to open the list of trading terminal plugins. All plugins in the strategy library of your current FMZ account will be displayed in this list for selection and use.
After completing the operation on the mobile APP, we use the following code to query the position of Binance's simulation bot:
```
function main() {
let apiBase = "https://testnet.binancefuture.com"
exchange.SetBase(apiBase)
let pos = exchange.IO("api", "GET", "/fapi/v2/positionRisk")
if (!pos) {
return
}
// View positions
return pos.filter(item => Number(item.positionAmt) != 0)
}
```

It can be seen that 6 positions have been opened, this is because when placing actual orders on the simulation bot, it's easy to trigger limit prices; in addition, due to the order amount of 10U, it's easy to trigger the minimum order amount limit of trading pairs; therefore a few trading pairs were not successfully ordered.
If you need to use this in reality, more practical situations should be considered in order to optimize this plugin for better usage. The code here is only used for teaching and communication purposes.

1,857,502 | Your client-side is not secure without these 5 practices | From HTML websites in the 1980s to progressive web apps in 2024, web development has come a long way.... | 0 | 2024-05-24T07:39:28 | https://dev.to/armstrong2035/5-considerations-for-client-side-security-5fk6 |
From HTML websites in the 1980s to progressive web apps in 2024, web development has come a long way. And as client-side capabilities have improved, so has the importance of security. We may get away with poor security on a static HTML page but modern websites store cookies, passwords, credit card information, and other data. As such, security for the client is more important than ever.
This article provides a high-level summary of client security. The article covers the following topics:
1. Input validation
2. User Authentication
3. User Authorization
4. Data protection
5. Secure communication
Each section has a description and a few techniques that you can implement. The article also offers a few code snippets in JavaScript. These code snippets are for demonstration purposes only.
Finally, I hope you enjoy reading this article. I certainly enjoyed writing it.
## Input Validation
Input validation is the process of filtering what users input into an application. Essential for client-side security, input validation is required but more is needed.
Consider the following scenario:. Someone wants to attack your website with a virus. So they go on the 'contact us' form. They then input characters that the browser will interpret as code and execute. Now your website is executing code that you did not design. This leads to all sorts of strange behavior, including stolen user data.
### Whitelisting vs Blacklisting
You could avoid all this by ensuring no malicious input enters your website. You could use any whitelisting technique. This means that you have a list of characters that the website allows. Anything else will be rejected. You could also use a blacklisting technique. A blacklist contains a list of characters that are NOT allowed. Generally, whitelisting is safer than blacklisting because blacklisting is more susceptible to [filter evasion](https://www.invicti.com/blog/web-security/xss-filter-evasion/#:~:text=XSS%20filter%20evasion%20refers%20to,and%20fool%20complex%20browser%20filters.)
### Semantic and Syntactic Validity
Any good input validation technique should also ensure both syntax and semantic validity. syntax validity ensures that an input is in the correct form or type. E.g., The CVV code for a credit card must always be three digits. Semantic validity ensures that the imputed data follows the correct context or order. For example, the expiration date of a debit card should always be a future date.
### Common input validation techniques
Now that you understand the basics of input validation, let us review some common techniques.
1. Built-in validation: involves the use of inbuilt HTML attributes such as required, pattern, type, min-length, max-length, pattern, and so on. [Read more here](https://developer.mozilla.org/en-US/docs/Learn/Forms/Form_validation#using_built-in_form_validation)
```html
<!-- Requiring a field -->
<input type="text" name="username" required>
<!-- Setting a pattern for input -->
<input type="text" name="phone" pattern="[0-9]{3}-[0-9]{3}-[0-9]{4}">
<!-- Limiting input length -->
<input type="text" name="zipcode" minlength="5" maxlength="9">
```
2. Sanitization: involves cleaning up an input that contains suspicious characters. [Read more here](https://developer.mozilla.org/en-US/docs/Web/API/Sanitizer)
```js
// Code to remove HTML tags from input
function sanitizeInput(input) {
return input.replace(/</g, '<').replace(/>/g, '>');
}
// Code to remove leading/trailing whitespace and limit to alphanumeric
function sanitizeUsername(username) {
return username.trim().replace(/[^a-zA-Z0-9]/g, '');
}
```
3. Regular Expressions (REGEX): useful for imposing a pattern in which data must be input. Only data that matches the preset pattern will be accepted! Regex is typically used for zip code or password form fields. [Here is an excellent blog about regular expressions](https://blog.openreplay.com/regular-expressions-and-input-validations/)
```js
// Password validation (at least 8 chars, 1 uppercase, 1 number)
const passwordPattern = /^(?=.*[A-Z])(?=.*\d).{8,}$/;
function validatePassword(password) {
return passwordPattern.test(password);
}
```
## User Authentication
User authentication is verifying a user’s identity before giving them access to their account and everything associated with it. Authentication is useful for user experience. But more importantly, it is a security measure that ensures that sensitive data is accessed only by authorized parties.
User authentication is essential to web security. Without it, user accounts are vulnerable to cyber-attacks. Consider a website without 2-factor authentication. It is easy to hack a user's account on such a website. All an attacker has to do is guess the user's password. That is why it is important to utilize the knowledge factor, possession factor, and inherence factor.
The knowledge factor authentication is based on knowledge that only the user would have. Security questions and passwords are in this category. The possession factor, however, refers to authentication that requires physical devices owned by the user. A physical cryptocurrency wallet is an example here. Finally, consider the inherence factor for authentication. It has to do with biometrics such as fingerprints, facial recognition, etc.
Generally, though, most security on the client is based on the knowledge factor. It is unlikely that a website would request fingerprints for access. Nevertheless, user authentication techniques for the client are based on either of those factors.
### Common authentication techniques:
1. Password-based authentication receives a password from a user in exchange for access. This is the most common form of user authentication/authorization. One issue with this approach is that weak passwords will be easily bypassed.
2. Multi-factor authentication (MFA) enforces several layers of authentication on users. E.g., in 2-factor authentication, you set a password and also receive a one-time passcode via SMS. The purpose of this extra layer is often to notify you of a potential hack on your account. Mixing the knowledge factor with the physical factor works here. For example, Gmail requires users to log in with a password and confirm the login on a device that they own!
3. Certificate Base Authority collaborates with a trusted authority to issue a unique certificate. e.g., the Microsoft Authenticator app is a trusted authority. The developer can use it to generate a unique code to authenticate a user. The user would then input the code to gain access.
4. Token-based authentication generates access tokens that give a user access to certain features. Tokens usually have a scope, i.e., they give restricted access to features. Tokens also expire. One example of this is the Spotify API Oauth sign-in. It allows third-party apps to make changes to users' accounts as long as an access token is part of the API call. First, the user gives the developer access to their account. Then Spotify sends the developer an access token. The developer then uses the token to perform actions within the scope of what the user has agreed to.
```js
// Basic password authentication
function authenticateUser(username, password) {
const user = database.findUser(username);
if (user && user.password === password) {
return true; // Authentication successful
}
return false; // Authentication failed
}
// 2-Factor Authentication with SMS code
function authenticate2FA(username, password, smsCode) {
if (authenticateUser(username, password)) {
if (verifyCode(username, smsCode)) {
return true; // 2FA successful
}
}
return false; // 2FA failed
}
```
## User Authorization
User authorization is the conditional issuance of permissions to different kinds of users of a website. Simply put, authorization determines what privileges different clients have. Authorization filters users based on varying conditions and gives access accordingly. An important mental model for thinking about this is as follows:
1. Subject: Who is the user?
2. Resource: which object does the user want to access?
3. Action: Which actions is the user trying to perform with the resource he has access to?
Consider business enterprise resource management software. For a given business, there are finance, human resources (HR), and product dashboards. Naturally, the head of finance has access to the finance dashboard. The head of HR has access to the HR dashboard, and the head of product uses the product dashboard. Imagine that the HR manager needs some information on his department's budget. We could simply give him/her limited access to the finance dashboard. Many of the tools that you use as a developer already have these features. Figma, Google, and even Jira all give conditional access to different features.
### Common user authorization techniques
Some user authorization methods are as follows:
1. Role-Based Access Control allows access to resources depending on the role of the user. For example, Google Docs has roles for editors, viewers, and commenters. Someone with the role of a commenter cannot access the features of an editor.
2. Attribute-Based Access Control filters different users based on their attributes. Consider a SAAS website with tiered pricing. Users either have access to premium features or not, depending on whether they have paid or not. One independent publisher on the internet noticed that excessive scrapping was affecting the performance of his website. So he put up a paywall to allow only paid users to access the content. This action improved the website's performance!
3. Privileged Access Management prevents regular users from accessing sensitive information. An excellent example of this is WordPress. WordPress websites are publicly accessible. Yet only the website administrators can make any changes to them.
```js
// Role-based access control
function authorize(user, resource, action) {
const role = user.role;
const permissions = roles[role];
const isAllowed = permissions.some(p =>
p.resource === resource && p.actions.includes(action)
);
return isAllowed;
}
// Attribute-based access control
function authorizePaidContent(user, resource) {
if (user.subscription === 'paid') {
return true; // Allow paid users
}
return false; // Block non-paid users
}
```
## Data Protection
Data protection is critical to client-side security. Modern web applications are complex. They also handle a lot of sensitive information. It is important to protect data for the following reasons:
1. Preventing Data Leakage: Data stored on the client side, such as user preferences, session tokens, and cached data, must be safeguarded to prevent unauthorized access or leakage.
2. Compliance Requirements: Adhering to data protection standards and regulations, such as GDPR, HIPAA, or CCPA, is essential to ensure the legal and ethical handling of user data.
3. Mitigating Security Risks: Data protection measures reduce the risk of data breaches, identity theft, and other security threats that exploit vulnerabilities in client-side data storage.
### Techniques for Data Protection
1. Encryption: Encrypting sensitive data before storing it on the client side ensures that even if accessed by unauthorized parties, the data remains unreadable without the decryption key. To do this, Use strong encryption algorithms such as AES (Advanced Encryption Standard) for encrypting data at rest and TLS (Transport Layer Security) for encrypting data in transit.
2. Data Masking and Tokenization: Masking sensitive data elements or tokenizing them into non-sensitive equivalents reduces the exposure of actual data, enhancing privacy and security.
Use tokenization services or libraries to generate and manage tokens for sensitive data fields, such as credit card numbers or personally identifiable information (PII).
3. Regular Security Audits and Updates: Conduct regular security audits and updates of your client-side data protection mechanisms to identify and address vulnerabilities proactively. Stay informed about emerging security threats and best practices in data protection to continually improve your application's security posture.
By implementing these data protection techniques, web developers can enhance the security and privacy of client-side data, thereby fostering user trust and compliance with regulatory requirements.
## Secure Communication
Secure communication is pivotal to safeguarding data integrity, confidentiality, and authenticity during transmission between clients and servers. Secure communication is important for the following reason:
1. Data Confidentiality: Encryption ensures that sensitive data exchanged between clients and servers remains confidential and unreadable to unauthorized entities.
2. Data Integrity: Secure communication protocols, such as HTTPS, prevent data tampering or modification during transmission, maintaining data integrity and trustworthiness.
3. Authentication and Identity Verification: Secure communication protocols enable mutual authentication between clients and servers, verifying the identities of both parties to prevent impersonation attacks.
4. Protection Against Eavesdropping: Encryption of data in transit mitigates the risk of eavesdropping or interception by malicious actors seeking to capture sensitive information.
### Techniques for Secure Communication
1. HTTPS (Hypertext Transfer Protocol Secure):
- Utilize HTTPS to encrypt data exchanged between clients and servers, providing a secure communication channel over the Internet.
- Obtain and install SSL/TLS certificates from trusted certificate authorities to enable HTTPS on your web servers.
2. TLS (Transport Layer Security):
- Implement the latest TLS versions (e.g., TLS 1.2 or TLS 1.3) with strong cipher suites to secure communication channels and protect against known vulnerabilities.
- Configure server-side security settings, such as Perfect Forward Secrecy (PFS), to enhance the resilience of TLS encryption.
3. Certificate-based Authentication:
- Employ certificate-based authentication mechanisms, such as client SSL certificates, to verify the identities of clients and servers during SSL/TLS handshake.
- Maintain a secure certificate management process, including certificate issuance, revocation, and renewal, to prevent certificate-related security incidents.
4. Content Security Policies (CSP):
- Implement CSP headers to define and enforce security policies regarding permitted content sources, mitigating risks associated with XSS attacks and content injection vulnerabilities.
- Specify strict CSP directives, such as 'default-src 'self'', 'script-src 'nonce-hash'', and 'upgrade-insecure-requests', to enhance web application security.
5. Secure WebSockets:
- When using WebSockets for real-time communication, ensure WebSocket connections are secured with SSL/TLS encryption to protect data exchanged between clients and servers.
- Apply WebSocket security best practices, such as rate limiting, origin validation, and message validation, to prevent WebSocket-based attacks and abuse.
6. Secure File Transfers:
- For file uploads or downloads, employ secure protocols such as SFTP (SSH File Transfer Protocol) or HTTPS with multipart form data to encrypt file transfers and prevent unauthorized access.
- Implement server-side file validation and sanitization to mitigate risks associated with malicious file uploads, including malware or script injections.
7. Network Security Measures:
- Deploy network security measures, such as firewalls, intrusion detection/prevention systems (IDS/IPS), and secure VPNs (Virtual Private Networks), to protect against network-based attacks and unauthorized access attempts.
- Monitor network traffic and perform regular security audits to detect and respond to anomalous or suspicious activities affecting secure communication channels.
By adopting these secure communication techniques and best practices, web developers can establish resilient and trustworthy communication channels, ensuring the confidentiality, integrity, and authenticity of data exchanged between clients and servers.
## Conclusion
Client security is essential to protecting user data and defending against cyberattacks. Here’s everything we covered in this article:
Input validation protects your website from SQL injections and other malicious input. User authentication and authorization are children of the same parent. Authentication ensures that only the owner or a user account can access it. Authorization creates permissions that limit or allow access to resources within a website. Finally, data protection is useful for securing the data that is stored on the client; while secure communication protects the data that travels between the server and the client.

1,862,413 | Stratégie : que va t-on (ne pas faire) cette année ? | J'ai vu cette scène se répéter encore et encore au cours de ma carrière (en cabinet de conseil puis... | 0 | 2024-05-24T07:38:55 | https://dev.to/psantus/strategie-que-va-t-on-ne-pas-faire-cette-annee--2gc3 | strategy, plan, management, agile | J'ai vu cette scène se répéter encore et encore au cours de ma carrière (en cabinet de conseil puis en entreprise) : devant un parterre de managers (au mieux) amusés ou (au pire) désabusés, le big boss dévoile son énième plan stratégique. Sur l'écran derrière lui, un slide identifiant 7 leviers, 8 axes, 10 piliers, 12 priorités.. Chacun a fait l'objet d'un groupe de travail et porte 4 ou 5 sous-axes ou projets. En introduction, un slide rappelait une ambition forte de croissance du CA.
Les patrons de BU sont soulagés : certes, dans chaque axe, le boss (aidé par ses consultants) a certes injecté de nouvelles priorités, mais ils ont réussi à faire en sorte que tous leurs projets en cours soient repris dans le plan stratégique, au prix d'un re-branding qui nécessitera un peu de conduite du changement.
Le DSI, seul, reste impassible, pendant que ses équipes découvrent médusés une augmentation de 150% de leur charge et des dates de livraison (pour lesquelles ils n'ont pas été consultés) ; il a eu la primeur des slides la veille mais doit la jouer corporate. S'il a un peu de bouteille, il sait que des arbitrages seront faits (inavouables aujourd'hui, et au prix de nombreuses discussions conflictuelles qui consommeront une énergie non-négligeable, mais de toute façon la capacité à faire n'augmentera pas).
Parfois, ce plan stratégique s'adjoint une gouvernance ad hoc (des comités de piliers et un comité central pour les gouverner tous - car le big boss ne va tout de même pas participer à chacun des comités de piliers, quand bien même ceux-ci étaient stratégiques) qui va un temps court-circuiter les canaux réguliers d'information et de prise de décision avant de disparaître silencieusement.
# De quoi ces plans à tiroirs sont-ils le signe ?
Commençons par affirmer que **ce type de plan n'est pas _vraiment_ un plan stratégique**. Il ne donne pas une claire vision de la difficulté ou menace que le management identifie comme principale, de ses enjeux ni de la nécessité d'une action coordonnée pour la résoudre, des défis et compétences/technologies/savoir-faire qui permettront à l'entreprise de les relever.
Dire cela est un peu facile et semble suggérer qu'il est aisé de dire _ce qu'est_ une stratégie (et surtout comment la définir). Or, c'est l'inverse : définir une stratégie est un vrai art, qui implique de discerner non pas dans une liste de projets (poussés par des salariés ou des parties extérieures intéressées) mais ce qui, dans l'ensemble des ambitions, peurs, désirs, objectifs, et valeurs antagonistes qui se présentent au dirigeant, forme un ensemble cohérent qui peut être traité par un plan suivi. C'est un exercice plus créatif qu'analytique (même si l'analyse et la confrontation aux données du problème sont nécessaires pour forger l'intuition qui sera au coeur du processus créatif).
Ce plan à tiroir n'est donc pas un plan stratégique mais il **n'est pas non plus un plan tactique** donnant une orientation claire aux équipes leur permettant d'agir efficacement.
---
Mais le plus grave, ce sont à mon sens les messages envoyés par l'existence même de ce type de plan et de la structure de gouvernance ad hoc associée :
- Le premier, c'est que **le dirigeant n'a pas confiance dans son management** (et, plus largement, dans les équipes) pour définir le plan tactique qui va permettre d'atteindre les objectifs stratégiques. Il renonce donc à son domaine exclusif (la stratégie) pour micro-manager le tactique.
- Le second, c'est que **l'organisation telle qu'elle existe n'est pas capable de prendre des virages** puisque, d'une part, il faut injecter une structure de gouvernance ad hoc pour la faire bouger et, d'autre part, il y a une course entre patrons de BU qui mesurent leur valeur/influence au nombre d'actions qu'ils parviennent à faire labelliser comme stratégiques.
- Le dernier, c'est qu'**elle est jugée irréformable** ou que le big boss n'a pas idée de comment construire une organisation qui saura adapter ses objectifs.
# 2 clés pour mieux faire
Si la valeur didactique d'un plan ne doit pas être négligée, en tant que l'effort de sensibilisation associé amènera chacun à intégrer ses éléments clés dans son agir local, un **plan vaut d'abord par son exécution** et la focalisation des forces de l'entreprise.
De ce point de vue, le temps passé à tous les étages pour étudier puis arbitrer dans la douleur entre tous les sous-piliers du plan stratégique l'est en pure perte. **Il me semble qu'un discours beaucoup plus efficace** serait le suivant :
> Voici la liste des projets / problématiques sur lesquelles il n'est pas nécessaire de passer du temps cette année.
On peut ajouter
> Il vous est interdit d'y consacrer des efforts, sauf à démontrer qu'il s'agit d'un prérequis absolu pour atteindre tel objectif stratégique.
Finalement, tout choix est un renoncement, et une approche de **la stratégie consiste effectivement à dire non pas ce qu'on doit faire, mais plutôt ce qu'on ne fera pas**. Agir ainsi redonne du temps, de la capacité d'initiative et de la confiance aux équipes.
---
La deuxième clé me semble de définir une organisation capable de prendre des virages, ou _pivoter_, quasiment sans frottement. De ce point de vue, **les méthodes agiles** sont irremplaçables, en particulier avec une organisation qui sépare le management hiérarchique (plutôt effectué par compétence) du management fonctionnel (le PO qui détermine ce qui va être dans la roadmap produit).
Une bonne équipe agile peut sans scrupule ni attachement excessif passer d'un produit à un autre et n'est pas attachée toute entière, dans son fonctionnement ou son intégrité, à l'existence de telle ou telle fonctionnalité ou produit.
Le produit lui-même, toujours et jamais fini à la fois (toujours, car ce qui est en production est qualitatif et fonctionnel, facilement refactorable, et jamais car le produit est conçu pour évoluer à un rythme toujours soutenable), peut évoluer dans le sens des nouveaux objectifs (qui, sauf révolution radicale, passeront par une repriorisation de la roadmap, exercice qu'une équipe fait de façon périodique sans qu'il y ait besoin pour cela d'une crise managériale)

New advances in the field of Generative AI are constantly emerging, and Retrieval-Augmented Generation (RAG) is the next to gain pace.
This blog post will discuss the applications and effectiveness of RAG models.
## Understanding Retrieval Augmented Generation
[Retrieval Augmented Generation](https://vectorize.io/what-is-retrieval-augmented-generation/) (RAG) is a cutting-edge approach in natural language processing that combines the strengths of information retrieval and text generation.
Here’s a simple breakdown of how it works and why it’s important.
## What is Retrieval Augmented Generation?
RAG models are designed to enhance the quality of generated text by incorporating relevant information retrieved from a large collection of documents.
This means that instead of generating responses based solely on a predefined dataset, the model first searches for relevant information and then uses that information to produce more accurate and contextually appropriate responses.
## Key Components of RAG Models
RAG models consist of two main parts:
**Retriever:** This component searches through a vast collection of documents (like a library or database) to find the most relevant pieces of information. Think of it as a smart search engine.
**Generator:** After the retriever finds the relevant information, the generator uses this information to craft a coherent and contextually appropriate response.
## How do RAG Models Differ from Traditional Models?
Traditional text generation models, like GPT-3, generate responses based purely on patterns learned during training.
In contrast, RAG models first retrieve relevant information before generating a response, ensuring that the output is grounded in actual data.
For example, if you ask a traditional model a question about a recent event, it might not provide up-to-date information because it relies on pre-existing knowledge.
A RAG model, however, can retrieve the latest information from a database and generate a more accurate answer.
### Real-World Impact
RAG models significantly enhance the quality and reliability of generated text.
Here are some numbers to illustrate their effectiveness:
**Accuracy Improvement:** Studies have shown that RAG models can improve the accuracy of generated answers by up to 30% compared to traditional models.
**Relevance:** The retrieved information can increase the relevance of responses by up to 50%, making them more useful and contextually appropriate.
**User Satisfaction:** In user studies, responses generated by RAG models received 25% higher satisfaction ratings than those generated by traditional models
## Applications of RAG Models
Retrieval Augmented Generation (RAG) models have revolutionized various domains within natural language processing by enhancing the quality and relevance of generated text.
Here, we delve into some of the key applications of RAG models, including Natural Language Processing, Question Answering Systems, Conversational AI, and other notable use cases.
### Natural Language Processing
Natural Language Processing (NLP) is a broad field encompassing various tasks aimed at enabling machines to understand, interpret, and generate human language.
RAG models have made significant contributions to several NLP tasks:
**Text Summarization:** By retrieving relevant information from large datasets, RAG models can generate concise and informative summaries, improving upon traditional models that may miss critical details.
**Machine Translation:** RAG models enhance translation quality by retrieving contextually relevant examples and phrases from a vast corpus, leading to more accurate and culturally appropriate translations.
**Sentiment Analysis:** By incorporating real-time data, RAG models can better understand the nuances of sentiment in text, providing more accurate and context-aware sentiment analysis.
### Question Answering Systems
Question Answering (QA) Systems are designed to provide precise answers to user queries. RAG models excel in this domain by leveraging their ability to retrieve and utilize specific information:
**Fact-Checking:** RAG models can retrieve the latest data from trusted sources, ensuring that the answers provided are up-to-date and accurate. This is particularly useful in dynamic fields such as news reporting and academic research.
**Contextual Answers:** Unlike traditional QA systems that might generate generic responses, RAG models can provide contextually rich answers by integrating relevant information from multiple documents. This leads to more informative and reliable answers.
**Domain-Specific QA:** In specialized fields such as medicine or law, RAG models can retrieve domain-specific knowledge, offering precise and contextually appropriate answers that adhere to industry standards.
### Conversational AI
Conversational AI encompasses technologies that enable machines to engage in human-like dialogue.
RAG models significantly enhance the capabilities of conversational agents:
**Customer Support:** RAG models can retrieve relevant information from a company’s knowledge base, providing accurate and timely responses to customer inquiries. This leads to improved customer satisfaction and reduced support costs.
**Personal Assistants:** By accessing vast amounts of data, RAG-powered virtual assistants can offer more personalized and context-aware advice, recommendations, and reminders.
**Interactive Learning:** In educational settings, conversational AI systems using RAG models can provide detailed explanations and answers to students, facilitating a more interactive and engaging learning experience.
## Other Use Cases
Beyond the primary applications, RAG models are also making an impact in various other fields:
**Content Creation:** RAG models assist writers and content creators by retrieving relevant information and generating high-quality content, saving time and enhancing creativity.
**Legal Document Analysis:** In the legal field, RAG models can retrieve pertinent case laws and statutes, aiding lawyers in preparing more robust legal arguments and documents.
**Healthcare:** RAG models can retrieve and synthesize medical literature, helping healthcare professionals stay updated with the latest research and providing patients with accurate health information.
**E-Commerce:** By integrating RAG models, e-commerce platforms can offer personalized product recommendations and detailed product descriptions, enhancing the shopping experience for users.
## Evaluating the Effectiveness of RAG Models
Evaluating the effectiveness of Retrieval Augmented Generation (RAG) models is crucial to understanding their performance and identifying areas for improvement.
This involves using various metrics and benchmark datasets to assess how well these models retrieve and generate relevant, accurate, and contextually appropriate responses.
### Metrics for Evaluation
To thoroughly evaluate RAG models, several metrics are commonly used:
**Precision and Recall:** Precision measures the accuracy of the retrieved documents. It is the ratio of relevant documents retrieved to the total documents retrieved.
**Recall:** Recall Measures the ability of the model to retrieve all relevant documents. It is the ratio of relevant documents retrieved to the total number of relevant documents.
**BLEU:** BLEU is commonly used to evaluate the quality of generated text by comparing it to one or more reference texts. It measures how many words or phrases in the generated text match the reference text.
Typically, BLEU scores range from 0 to 1, where a higher score indicates better alignment with the reference text.
**ROUGE:** ROUGE measures the overlap between the generated text and reference text, focusing on recall. It is particularly useful for summarization tasks.
### Human Evaluation
Human judges are often employed to assess the quality of the generated responses based on criteria such as relevance, coherence, fluency, and informativeness.
This evaluation provides qualitative insights that automated metrics might miss.

1,863,663 | DashVector + ModelScope 玩转多模态检索 | 本教程演示如何使用向量检索服务（DashVector），结合ModelScope上的中文CLIP多模态检索模型，构建实时的"文本搜图片"的多模态检索能力。作为示例，我们采用多模态牧歌数据集作为图片语料库... | 0 | 2024-05-24T07:32:32 | https://dev.to/dashvector/dashvector-modelscope-wan-zhuan-duo-mo-tai-jian-suo-5aad | 本教程演示如何使用向量检索服务（DashVector），结合[ModelScope](https://modelscope.cn/home)上的[中文CLIP](https://modelscope.cn/models/damo/multi-modal_clip-vit-large-patch14_zh/summary)多模态检索模型，构建实时的"文本搜图片"的多模态检索能力。作为示例，我们采用[多模态牧歌数据集](https://modelscope.cn/datasets/modelscope/muge/summary)作为图片语料库，用户通过输入文本来跨模态检索最相似的图片。
整体流程
-------------
主要分为两个阶段：
1. **图片数据Embedding入库** 。将牧歌数据集通过中文CLIP模型Embedding接口转化为高维向量，然后写入DashVector向量检索服务。
2. **文本Query检索** 。使用对应的中文CLIP模型获取文本的Embedding向量，然后通过DashVector检索相似图片。
前提准备
-------------
### 1. API-KEY 准备
* 开通向量检索服务：请参见[开通服务](https://help.aliyun.com/document_detail/2568083.html?spm=a2c4g.2510236.0.i8)。
* 创建向量检索服务API-KEY：请参见[API-KEY管理](https://help.aliyun.com/document_detail/2510230.html?spm=a2c4g.2510234.0.i9)。
### 2. 环境准备
本教程使用的是ModelScope最新的CLIP [Huge模型(224分辨率)](https://www.modelscope.cn/#/models/damo/multi-modal_clip-vit-huge-patch14_zh/summary)，该模型使用大规模中文数据进行训练（\~2亿图文对），在中文图文检索和图像、文本的表征提取等场景表现优异。根据模型官网教程，我们提取出相关的环境依赖如下：
**说明**
需要提前安装 Python3.7 及以上版本，请确保相应的 python 版本
```
# 安装 dashvector 客户端
pip3 install dashvector
# 安装 modelscope
# require modelscope>=0.3.7，目前默认已经超过，您检查一下即可
# 按照更新镜像的方法处理或者下面的方法
pip3 install --upgrade modelscope -f https://modelscope.oss-cn-beijing.aliyuncs.com/releases/repo.html
# 需要单独安装decord
# pip3 install decord
# 另外，modelscope 的安装过程会出现其他的依赖，当前版本的依赖列举如下
# pip3 install torch torchvision opencv-python timm librosa fairseq transformers unicodedata2 zhconv rapidfuzz
```
### 3. 数据准备
本教程使用[多模态牧歌数据集](https://modelscope.cn/datasets/modelscope/muge/summary)的validation验证集作为入库的图片数据集，可以通过调用ModelScope的[数据集](https://modelscope.cn/docs/%E6%95%B0%E6%8D%AE%E9%9B%86%E4%BB%8B%E7%BB%8D)接口获取。
```
from modelscope.msdatasets import MsDataset
dataset = MsDataset.load("muge", split="validation")
```
具体步骤
-------------
**说明**
本教程所涉及的 *your-xxx-api-key* 以及 *your-xxx-cluster-endpoint* ，均需要替换为您自己的API-KAY及CLUSTER_ENDPOINT后，代码才能正常运行。
### 1. 图片数据Embedding入库
[多模态牧歌数据集](https://modelscope.cn/datasets/modelscope/muge/summary)的 validation 验证集包含 30588 张多模态场景的图片数据信息，这里我们需要通过CLIP模型提取原始图片的Embedding向量入库，另外为了方便后续的图片展示，我们也将原始图片数据编码后一起入库。代码实例如下：
```
import torch
from modelscope.utils.constant import Tasks
from modelscope.pipelines import pipeline
from modelscope.msdatasets import MsDataset
from dashvector import Client, Doc, DashVectorException, DashVectorCode
from PIL import Image
import base64
import io
def image2str(image):
image_byte_arr = io.BytesIO()
image.save(image_byte_arr, format='PNG')
image_bytes = image_byte_arr.getvalue()
return base64.b64encode(image_bytes).decode()
if __name__ == '__main__':
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 创建集合：指定集合名称和向量维度, CLIP huge 模型产生的向量统一为 1024 维
rsp = client.create('muge_embedding', 1024)
if not rsp:
raise DashVectorException(rsp.code, reason=rsp.message)
# 批量生成图片Embedding，并完成向量入库
collection = client.get('muge_embedding')
pipe = pipeline(task=Tasks.multi_modal_embedding,
model='damo/multi-modal_clip-vit-huge-patch14_zh',
model_revision='v1.0.0')
ds = MsDataset.load("muge", split="validation")
BATCH_COUNT = 10
TOTAL_DATA_NUM = len(ds)
print(f"Start indexing muge validation data, total data size: {TOTAL_DATA_NUM}, batch size:{BATCH_COUNT}")
idx = 0
while idx < TOTAL_DATA_NUM:
batch_range = range(idx, idx + BATCH_COUNT) if idx + BATCH_COUNT <= TOTAL_DATA_NUM else range(idx, TOTAL_DATA_NUM)
images = [ds[i]['image'] for i in batch_range]
# 中文 CLIP 模型生成图片 Embedding 向量
image_embeddings = pipe.forward({'img': images})['img_embedding']
image_vectors = image_embeddings.detach().cpu().numpy()
collection.insert(
[
Doc(
id=str(img_id),
vector=img_vec,
fields={'png_img': image2str(img)}
)
for img_id, img_vec, img in zip(batch_range, image_vectors, images)
]
)
idx += BATCH_COUNT
print("Finish indexing muge validation data")
```
**说明**
上述代码里模型默认在 cpu 环境下运行，在 gpu 环境下会视 gpu 性能得到不同程度的性能提升
### 2. 文本Query检索
完成上述图片数据向量化入库后，我们可以输入文本，通过同样的CLIP Embedding模型获取文本向量，再通过DashVector向量检索服务的检索接口，快速检索相似的图片了，代码示例如下：
```
import torch
from modelscope.utils.constant import Tasks
from modelscope.pipelines import pipeline
from modelscope.msdatasets import MsDataset
from dashvector import Client, Doc, DashVectorException
from PIL import Image
import base64
import io
def str2image(image_str):
image_bytes = base64.b64decode(image_str)
return Image.open(io.BytesIO(image_bytes))
def multi_modal_search(input_text):
# 初始化 DashVector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('muge_embedding')
# 获取文本 query 的 Embedding 向量
pipe = pipeline(task=Tasks.multi_modal_embedding,
model='damo/multi-modal_clip-vit-huge-patch14_zh', model_revision='v1.0.0')
text_embedding = pipe.forward({'text': input_text})['text_embedding'] # 2D Tensor, [文本数, 特征维度]
text_vector = text_embedding.detach().cpu().numpy()[0]
# DashVector 向量检索
rsp = collection.query(text_vector, topk=3)
image_list = list()
for doc in rsp:
image_str = doc.fields['png_img']
image_list.append(str2image(image_str))
return image_list
if __name__ == '__main__':
text_query = "戴眼镜的狗"
images = multi_modal_search(text_query)
for img in images:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
```

## Getting perf to work up to a point
Apparently the [opensbi-mediated](https://github.com/riscv-software-src/opensbi/blob/master/docs/pmu_support.md) access to the performance counter does not map so using the usual `cycles` and `instructions` event works in `perf record`. I got this board mainly to help with [dav1d](https://code.videolan.org/videolan/dav1d) development efforts, so not having perf support would make harder to reason about performance.
The best workaround after a [discussion in the forums](https://forum.banana-pi.org/t/perf-record-does-not-seem-to-work-is-the-device-tree-with-the-wrong-information/18051/11), is to build the `pmu-events` to include custom ones and then rely on the overly precise cpu-specific events instead:
```
$ perf list | grep cycle
bus-cycles [Hardware event]
cpu-cycles OR cycles [Hardware event]
ref-cycles [Hardware event]
stalled-cycles-backend OR idle-cycles-backend [Hardware event]
stalled-cycles-frontend OR idle-cycles-frontend [Hardware event]

### Building perf
Perf way to deal with cpu-specific events is through some machinery called jevents.
It lives in `tools/perf/pmu-events` and you can manually trigger it with.
``` sh
./jevents.py riscv arch pmu-events.c
```
And produce C code from a bunch of JSON and a CSV map file.
When I tried build the sources the first time I tried to cut it by setting most `NO_{}` make variables and left `NO_JEVENTS=1`, luckily I fixed it after noticing the different output in the forum.
``` sh
## I assume you have here the custom linux sources
cd /usr/src/pi-linux/tools/perf
## being lazy I disabled about everything instead of installing dependencies, one time I disabled too much.
make -j 8 V=1 VF=1 HOSTCC=riscv64-unknown-linux-gnu-gcc HOSTLD=riscv64-unknown-linux-gnu-ld CC=riscv64-unknown-linux-gnu-gcc CXX=riscv64-unknown-linux-gnu-g++ AR=riscv64-unknown-linux-gnu-ar LD=riscv64-unknown-linux-gnu-ld NM=riscv64-unknown-linux-gnu-nm PKG_CONFIG=riscv64-unknown-linux-gnu-pkg-config prefix=/usr bindir_relative=bin tipdir=share/doc/perf-6.8 'EXTRA_CFLAGS=-O2 -pipe' 'EXTRA_LDFLAGS=-Wl,-O1 -Wl,--as-needed' ARCH=riscv BUILD_BPF_SKEL= BUILD_NONDISTRO=1 JDIR= CORESIGHT= GTK2= feature-gtk2-infobar= NO_AUXTRACE= NO_BACKTRACE= NO_DEMANGLE= NO_JEVENTS=0 NO_JVMTI=1 NO_LIBAUDIT=1 NO_LIBBABELTRACE=1 NO_LIBBIONIC=1 NO_LIBBPF=1 NO_LIBCAP=1 NO_LIBCRYPTO= NO_LIBDW_DWARF_UNWIND= NO_LIBELF= NO_LIBNUMA=1 NO_LIBPERL=1 NO_LIBPFM4=1 NO_LIBPYTHON=1 NO_LIBTRACEEVENT= NO_LIBUNWIND=1 NO_LIBZSTD=1 NO_SDT=1 NO_SLANG=1 NO_LZMA=1 NO_ZLIB= TCMALLOC= WERROR=0 LIBDIR=/usr/libexec/perf-core libdir=/usr/lib64 plugindir=/usr/lib64/perf/plugins -f Makefile.perf install
```
Now I have a `perf` with still `cycles` and `instructions` not working with `perf record`, I wonder if there is a way at opensbi or kernel level to aggregate events to make it work properly, but I never had to look into perf internals so probably I poke it way later if nobody address it otherwise, anyway
```
perf record --group -e u_mode_cycle,m_mode_cycle,s_mode_cycle
```
produces something close enough for cycles, well `u_mode_cycle` is enough.
While for instructions the situation is a bit more annoying
```
perf record --group -e alu_inst,amo_inst,atomic_inst,fp_div_inst,fp_inst,fp_load_inst,fp_store_inst,load_inst,lr_inst,mult_inst,sc_inst,store_inst,unaligned_load_inst,unaligned_store_inst
```
is close to count all the scalar instructions, but trying to add `vector_div_inst,vector_inst,vector_load_inst,vector_store_inst` somehow makes perf record stop collecting samples silently, adding just 3 more events works though, so I guess I can be happy with `u_mode_cycle,alu_inst,atomic_inst,fp_inst,vector_inst` at least.

* [DashVector + ModelScope 玩转多模态检索](https://help.aliyun.com/document_detail/2510236.html?spm=a2c4g.2568028.0.i10)
* [DashScope](https://dashscope.aliyun.com/)
* [ONE-PEACE多模态模型](https://help.aliyun.com/zh/dashscope/developer-reference/one-peace-multimodal-embedding-quick-start)
**整体流程**
-------------------------
主要分为两个阶段：
1. **多模态数据Embedding入库** 。通过ONE-PEACE模型服务[Embedding](https://help.aliyun.com/zh/dashscope/developer-reference/one-peace-multimodal-embedding-api-details)接口将多种模态的数据集数据转化为高维向量。
2. **多模态Query检索** 。基于ONE-PEACE模型提供的多模态Embedding能力，我们可以自由组合不同模态的输入，例如单文本、文本+音频、音频+图片等多模态输入，获取Embedding向量后通过DashVector跨模态检索相似结果。
**前提准备**
-------------------------
### **1. API-KEY 准备**
* 开通灵积模型服务，并获得API-KEY：[开通DashScope并创建API-KEY](t2312925.md#)
* 开通DashVector向量检索服务，并获得API-KEY：[API-KEY管理](t2364363.md#)
### 2. 环境准备
本教程使用的多模态推理模型服务是DashScope最新的[ONE-PEACE模型](https://help.aliyun.com/zh/dashscope/developer-reference/one-peace-multimodal-embedding-root)。ONE-PEACE是一个图文音三模态通用表征模型，在语义分割、音文检索、音频分类和视觉定位几个任务都达到了新SOTA表现，在视频分类、图像分类图文检索、以及多模态经典benchmark也都取得了比较领先的结果。模型相关的环境依赖如下：
**说明**
需要提前安装Python3.7 及以上版本，请确保相应的python版本。
```
# 安装 dashscope 和 dashvector sdk
pip3 install dashscope dashvector
```
基本检索
-------------
### 1. 数据准备
**说明**
由于DashScope的ONE-PEACE模型服务当前只支持URL形式的图片、音频输入，因此需要将数据集提前上传到公共网络存储（例如 oss/s3），并获取对应图片、音频的url地址列表。
当前示例场景使用[ImageNet-1k](https://www.image-net.org/index.php)的validation数据集作为入库的图片数据集，将原始图片数据Embedding入库。检索时使用[ESC-50](https://github.com/karolpiczak/ESC-50)数据集作为音频输入，文本和图片输入由用户自定义，用户也可对不同模态数据自由组合。
* [Dataset for ImageNet-1k](https://www.image-net.org/download.php)
* [Dataset for ESC-50](https://github.com/karolpiczak/ESC-50)
### 2. 数据Embedding入库
**说明**
本教程所涉及的 *your-xxx-api-key* 以及 *your-xxx-cluster-endpoint* ，均需要替换为您自己的API-KAY及CLUSTER_ENDPOINT后，代码才能正常运行。
ImageNet-1k的validation数据集包含50000张标注好的图片数据，其中包含1000个类别，每个类别50张图片，这里我们基于ONE-PEACE模型提取原始图片的Embedding向量入库，另外为了方便后续的图片展示，我们也将原始图片的url一起入库。代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client, Doc, DashVectorException
dashscope.api_key = '{your-dashscope-api-key}'
# 由于 ONE-PEACE 模型服务当前只支持 url 形式的图片、音频输入，因此用户需要将数据集提前上传到
# 公共网络存储（例如 oss/s3），并获取对应图片、音频的 url 列表。
# 该文件每行存储数据集单张图片的公共 url，与当前python脚本位于同目录下
IMAGENET1K_URLS_FILE_PATH = "imagenet1k-urls.txt"
def index_image():
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 创建集合：指定集合名称和向量维度, ONE-PEACE 模型产生的向量统一为 1536 维
rsp = client.create('imagenet1k_val_embedding', 1536)
if not rsp:
raise DashVectorException(rsp.code, reason=rsp.message)
# 调用 dashscope ONE-PEACE 模型生成图片 Embedding，并插入 dashvector
collection = client.get('imagenet1k_val_embedding')
with open(IMAGENET1K_URLS_FILE_PATH, 'r') as file:
for i, line in enumerate(file):
url = line.strip('\n')
input = [{'image': url}]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
print(f"ONE-PEACE failed to generate embedding of {url}, result: {result}")
continue
embedding = result.output["embedding"]
collection.insert(
Doc(
id=str(i),
vector=embedding,
fields={'image_url': url}
)
)
if (i + 1) % 100 == 0:
print(f"---- Succeeded to insert {i + 1} image embeddings")
if __name__ == '__main__':
index_image()
```
**说明**
1. 上述代码需要访问DashScope的ONE-PEACE多模态Embedding模型，总体运行速度视用户开通该服务的qps有所不同。
2. 因图片大小影响ONE-PEACE模型获取Embedding的成功与否，上述代码运行后最终入库数据可能小于50000条。
### 3. 模态检索
#### **3.1. 文本检索**
对于单文本模态检索，可以通过ONE-PEACE模型获取文本Embedding向量，再通过DashVector向量检索服务的检索接口，快速检索相似的底库图片。这里文本query是猫 "cat"，代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image(image_list):
for img in image_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
def text_search(input_text):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('imagenet1k_val_embedding')
# 获取文本 query 的 Embedding 向量
input = [{'text': input_text}]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
text_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(text_vector, topk=3)
image_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img = Image.open(urlopen(img_url))
image_list.append(img)
return image_list
if __name__ == '__main__':
"""文本检索"""
# 猫
text_query = "cat"
show_image(text_search(text_query))
```
运行上述代码，检索结果如下：
#### 3.2. 音频检索
单音频模态检索与文本检索类似，这里音频query取自ESC-50的"猫叫声"片段，代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image(image_list):
for img in image_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
def audio_search(input_audio):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('imagenet1k_val_embedding')
# 获取音频 query 的 Embedding 向量
input = [{'audio': input_audio}]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
audio_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(audio_vector, topk=3)
image_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img = Image.open(urlopen(img_url))
image_list.append(img)
return image_list
if __name__ == '__main__':
"""音频检索"""
# 猫叫声
audio_url = "http://proxima-internal.oss-cn-zhangjiakou.aliyuncs.com/audio-dataset/esc-50/1-47819-A-5.wav"
show_image(audio_search(audio_url))
```
运行上述代码，检索结果如下：
#### 3.3. 文本+音频检索
接下来，我们尝试"文本+音频"联合模态检索，同上，首先通过ONE-PEACE模型获取"文本+音频"输入的Embedding向量，再通过DashVector向量检索服务检索结果。这里的文本query选取的是草地"grass"，音频query依然选择的是ESC-50的"猫叫声"片段。代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image(image_list):
for img in image_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
def text_audio_search(input_text, input_audio):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('imagenet1k_val_embedding')
# 获取文本+音频 query 的 Embedding 向量
input = [
{'text': input_text},
{'audio': input_audio},
]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
text_audio_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(text_audio_vector, topk=3)
image_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img = Image.open(urlopen(img_url))
image_list.append(img)
return image_list
if __name__ == '__main__':
"""文本+音频检索"""
# 草地
text_query = "grass"
# 猫叫声
audio_url = "http://proxima-internal.oss-cn-zhangjiakou.aliyuncs.com/audio-dataset/esc-50/1-47819-A-5.wav"
show_image(text_audio_search(text_query, audio_url))
```
运行上述代码，检索结果如下：
#### 3.4. 图片+音频检索
我们再尝试下"图片+音频"联合模态检索，与前述"文本+音频"检索类似，这里的图片选取的是草地图像（需先上传到公共网络存储并获取 url），音频query依然选择的是ESC-50的"猫叫声"片段。代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image(image_list):
for img in image_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
def image_audio_search(input_image, input_audio):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('imagenet1k_val_embedding')
# 获取图片+音频 query 的 Embedding 向量
# 注意，这里音频 audio 模态输入的权重参数 factor 为 2（默认为1）
# 目的是为了增大音频输入（猫叫声）对检索结果的影响
input = [
{'factor': 1, 'image': input_image},
{'factor': 2, 'audio': input_audio},
]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
image_audio_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(image_audio_vector, topk=3)
image_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img = Image.open(urlopen(img_url))
image_list.append(img)
return image_list
if __name__ == '__main__':
"""图片+音频检索"""
# 草地
image_url = "http://proxima-internal.oss-cn-zhangjiakou.aliyuncs.com/image-dataset/grass-field.jpeg"
# 猫叫声
audio_url = "http://proxima-internal.oss-cn-zhangjiakou.aliyuncs.com/audio-dataset/esc-50/1-47819-A-5.wav"
show_image(image_audio_search(image_url, audio_url))
```
输入示意图如下：
运行代码，检索结果如下：
进阶使用
-------------
上述场景里作为检索底库数据的是单模态的图片数据，这里我们也可以将多种模态的数据同时通过ONE-PEACE模型获取Embedding向量，将Embedding向量作为检索库数据入库检索，观察检索效果。
### 1. 数据准备
本示例场景使用[微软COCO](https://cocodataset.org/)在Captioning场景下的validation数据集，将图片以及对应的图片描述caption文本两种模态数据一起Embedding入库。对于检索时输入的图片、音频与文本等多模态数据，用户可以自定义，也可以使用公共数据集的数据。
* [Dataset for MSCOCO](https://cocodataset.org/#download)
### 2. 数据Embedding入库
**说明**
本教程所涉及的 *your-xxx-api-key* 以及 *your-xxx-cluster-endpoint* ，均需要替换为您自己的API-KAY及CLUSTER_ENDPOINT后，代码才能正常运行。
微软COCO的Captioning validation验证集包含5000张标注良好的图片及对应的说明文本，这里我们需要通过 DashScope的ONE-PEACE模型提取数据集的"图片+文本"的Embedding向量入库，另外为了方便后续的图片展示，我们也将原始图片url和对应caption文本一起入库。代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client, Doc, DashVectorException
dashscope.api_key = '{your-dashscope-api-key}'
# 由于 ONE-PEACE 模型服务当前只支持 url 形式的图片、音频输入，因此用户需要将数据集提前上传到
# 公共网络存储（例如 oss/s3），并获取对应图片、音频的 url 列表。
# 该文件每行存储数据集单张图片的公共 url 和对应的 caption 文本，以`;`分割
COCO_CAPTIONING_URLS_FILE_PATH = "cocoval5k-urls-captions.txt"
def index_image_text():
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 创建集合：指定集合名称和向量维度, ONE-PEACE 模型产生的向量统一为 1536 维
rsp = client.create('coco_val_embedding', 1536)
if not rsp:
raise DashVectorException(rsp.code, reason=rsp.message)
# 调用 dashscope ONE-PEACE 模型生成图片 Embedding，并插入 dashvector
collection = client.get('coco_val_embedding')
with open(COCO_CAPTIONING_URLS_FILE_PATH, 'r') as file:
for i, line in enumerate(file):
url, caption = line.strip('\n').split(";")
input = [
{'text': caption},
{'image': url},
]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
print(f"ONE-PEACE failed to generate embedding of {url}, result: {result}")
continue
embedding = result.output["embedding"]
collection.insert(
Doc(
id=str(i),
vector=embedding,
fields={'image_url': url, 'image_caption': caption}
)
)
if (i + 1) % 20 == 0:
print(f"---- Succeeded to insert {i + 1} image embeddings")
if __name__ == '__main__':
index_image_text()
```
**说明**
上述代码需要访问DashScope的ONE-PEACE多模态Embedding模型，总体运行速度视用户开通该服务的qps有所不同。
### 3. 模态检索
#### 3.1. 文本检索
首先我们尝试单文本模态检索。代码示例如下：
Python
```python
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image_text(image_text_list):
for img, cap in image_text_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
print(cap)
def text_search(input_text):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('coco_val_embedding')
# 获取文本 query 的 Embedding 向量
input = [{'text': input_text}]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
text_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(text_vector, topk=3)
image_text_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img_cap = doc.fields['image_caption']
img = Image.open(urlopen(img_url))
image_text_list.append((img, img_cap))
return image_text_list
if __name__ == '__main__':
"""文本检索"""
# 狗
text_query = "dog"
show_image_text(text_search(text_query))
```
运行上述代码，检索结果如下：
#### 3.2. 音频检索
我们再尝试单音频模态检索。我们使用ESC-50数据集的"狗叫声片段"作为音频输入，代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image_text(image_text_list):
for img, cap in image_text_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
print(cap)
def audio_search(input_audio):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('coco_val_embedding')
# 获取音频 query 的 Embedding 向量
input = [{'audio': input_audio}]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
audio_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(audio_vector, topk=3)
image_text_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img_cap = doc.fields['image_caption']
img = Image.open(urlopen(img_url))
image_text_list.append((img, img_cap))
return image_text_list
if __name__ == '__main__':
""""音频检索"""
# dog bark
audio_url = "http://proxima-internal.oss-cn-zhangjiakou.aliyuncs.com/audio-dataset/esc-50/1-100032-A-0.wav"
show_image_text(audio_search(audio_url))
```
运行上述代码，检索结果如下：
#### 3.3. 文本+音频检索
进一步的，我们尝试使用"文本+音频"进行双模态检索。这里使用ESC-50数据集的"狗叫声片段"作为音频输入，另外使用"beach"作为文本输入，代码示例如下：
```
import dashscope
from dashscope import MultiModalEmbedding
from dashvector import Client
from urllib.request import urlopen
from PIL import Image
dashscope.api_key = '{your-dashscope-api-key}'
def show_image_text(image_text_list):
for img, cap in image_text_list:
# 注意：show() 函数在 Linux 服务器上可能需要安装必要的图像浏览器组件才生效
# 建议在支持 jupyter notebook 的服务器上运行该代码
img.show()
print(cap)
def text_audio_search(input_text, input_audio):
# 初始化 dashvector client
client = Client(
api_key='{your-dashvector-api-key}',
endpoint='{your-dashvector-cluster-endpoint}'
)
# 获取上述入库的集合
collection = client.get('coco_val_embedding')
# 获取文本+音频 query 的 Embedding 向量
input = [
{'text': input_text},
{'audio': input_audio},
]
result = MultiModalEmbedding.call(model=MultiModalEmbedding.Models.multimodal_embedding_one_peace_v1,
input=input,
auto_truncation=True)
if result.status_code != 200:
raise Exception(f"ONE-PEACE failed to generate embedding of {input}, result: {result}")
text_audio_vector = result.output["embedding"]
# DashVector 向量检索
rsp = collection.query(text_audio_vector, topk=3)
image_text_list = list()
for doc in rsp:
img_url = doc.fields['image_url']
img_cap = doc.fields['image_caption']
img = Image.open(urlopen(img_url))
image_text_list.append((img, img_cap))
return image_text_list
if __name__ == '__main__':
"""文本+音频检索"""
text_query = "beach"
# 狗叫声
audio_url = "http://proxima-internal.oss-cn-zhangjiakou.aliyuncs.com/audio-dataset/esc-50/1-100032-A-0.wav"
show_image_text(text_audio_search(text_query, audio_url))
```
运行上述代码，检索结果如下：
观察上述检索结果，发现后两张图的重点更多的是在展示 "beach" 文本输入对应的沙滩，而 "狗叫声片段"音频输入指示的狗的图片形象则不明显，其中第二张图需要放大后才可以看到图片中站立在水中的狗，第三张图中基本没有狗的形象。
对于上述情况，我们可以通过[调整不同输入的权重](https://help.aliyun.com/zh/dashscope/developer-reference/one-peace-multimodal-embedding-api-details)来设置mbedding向量中哪种模态占更大的比重，从而在检索中突出重点。例如对于上述代码，我们可以给予"狗叫声片段"更大的权重，重点突出检索结果里狗的形象。
```
# 其他代码一致
# 通过 `factor` 参数来调整不同模态输入的权重，默认为 1，这里设置 audio 为 2
input = [
{'factor': 1, 'text': input_text},
{'factor': 2, 'audio': input_audio},
]
```
替换 `input`后，运行上述代码，结果如下：

Unlike the current centralized web, Web3 aims to democratize the internet, giving users control over their data and digital interactions.
Decentralized Ownership and Control
At the heart of Web3 is the concept of decentralized ownership. In the traditional Web2 model, a few large corporations control most of the internet's infrastructure and data. This centralization leads to issues like data breaches, censorship, and lack of user autonomy.
Web3 shifts the control from these centralized entities to individual users through blockchain technology. By distributing data across a network of nodes, Web3 ensures that no single entity has control over the entire network. This decentralization enhances security and fosters a more open and equitable internet.
Token Economy and Incentives
Web3 introduces a token economy, where digital tokens are used to incentivize and reward network participants. These tokens can represent various assets, including currency, ownership stakes, or access rights. Users can earn tokens by contributing to the network, such as providing computing power, creating content, or maintaining the blockchain.
This token-based incentive model encourages active participation and collaboration, driving the growth and sustainability of decentralized networks. It also allows users to monetize their contributions, creating new economic opportunities and reducing the reliance on traditional financial systems.
Interoperability and Composability
One of the strengths of Web3 is its focus on interoperability and composability. Interoperability refers to the ability of different blockchain networks and protocols to work together seamlessly. This enables users to transfer assets and data across various platforms without friction.
Composability allows developers to build on top of existing protocols and applications, creating a modular and flexible ecosystem. This approach fosters innovation and accelerates the development of new decentralized applications (dApps), as developers can leverage existing infrastructure and integrate various services.
Challenges and Opportunities
While Web3 holds great promise, it also faces significant challenges. Scalability, user experience, and regulatory uncertainty are some of the hurdles that need to be addressed for widespread adoption. However, the rapid pace of innovation and the growing interest in decentralized technologies suggest that these challenges will be overcome.
Opportunities abound in the Web3 space, from decentralized finance (DeFi) and non-fungible tokens (NFTs) to decentralized social networks and data marketplaces. As more people recognize the benefits of a decentralized internet, we can expect to see a surge in Web3 adoption and innovation.
Conclusion
Web3 is more than just a technological advancement; it represents a fundamental shift in how we interact with the internet. By decentralizing ownership and control, creating a token economy, and promoting interoperability, Web3 aims to democratize the digital world.
As we move towards this new era, the principles of Web3 will shape the future of the internet, making it more transparent, secure, and user-centric. The journey towards a fully decentralized web is just beginning, and the potential impact on society is profound. | alexroor4 |
