**Introduction**
The financial industry has long relied on technology to drive efficiency, accuracy, and innovation. Among the programming languages that have stood the test of time, **Java** remains a stalwart choice for building robust financial systems. In this article, we’ll explore why Java continues to play a crucial role in the finance sector.

#1. A Historical Perspective
Java’s journey in finance dates back several decades. From the early days of electronic communication networks (ECNs) to today’s algorithmic trading platforms, Java has been a constant companion. Let’s take a brief look at its evolution:

**Instinet and Island ECN:** In the late 1990s, Island ECN, a small-order matching system, gained prominence. Initially written in FoxPro, it later transitioned to Java. The lesson? Architecture and algorithms matter more than raw platform speed.

#2. Real-Time Performance
**Why Real-Time Matters:** Financial markets operate at lightning speed. Java’s real-time capabilities, thanks to high-performance JIT compilers and optimized garbage collection, make it an ideal choice for handling market data, order execution, and risk assessment.

#3. Stability and Resilience
**Surviving Market Crashes:** The pandemic-driven market crash of 2020 tested financial systems’ resilience. Java proved its mettle by handling increased trading volumes without breaking a sweat. Stability matters when every millisecond counts.

#4. Cross-Platform Compatibility
**Write Once, Run Anywhere:** Java’s “write once, run anywhere” philosophy ensures that financial applications work seamlessly across diverse platforms. This flexibility is critical for global financial institutions.

#5. Ecosystem and Libraries
**Vast Ecosystem:** Java boasts an extensive ecosystem of libraries, frameworks, and tools. From Spring to Apache Kafka, developers have powerful resources at their disposal.

#6. Security and Compliance
**Security First:** Financial systems deal with sensitive data. Java’s security features, including robust authentication and encryption, align well with industry standards

#7. Future-Proofing with Java 17
**Java 17 Features:** Highlight the latest features, such as pattern matching, sealed classes, and records. Discuss how they enhance code quality and maintainability.

**Conclusion**
Java’s legacy in finance is not just about lines of code; it’s about powering the heartbeat of global markets. As the industry evolves, Java adapts, ensuring stability, performance, and security. So, the next time you see a stock trade executed swiftly, remember that Java is behind the scenes, making it happen.

Dasturlash tilida yozilgan kodni mashina tushinadigan tilga o'girilishi compiling deyiladi.

C# code --> C# Compiler --> IL Code --> .Net Runtime

.Net Runtime 2 qismga bo'linadi: 1) JIT     2) GC

IL(Intermediate language) - bu odamlar tushunishi qiyin, ammo mashinaga tushunmaydgan dasturlash compilerdir. Vazifasi Runtime IL kodni kerak bo'lganda mashina tiliga o'girib CPU ga jo'natadi.

JIT(Just in Time compiler) - IL compileriga o'girilgan kodni faqatgina kerakli qismini o'rnida kompilatsiya qilib beradi.

GC(Garbage Collector) - keraksiz obyekt va resurslarni xotiradan tozalab, sistemaga qaytarib beradi.

Bu komponentlar hammasi birlashib CLR (Common Language Runtime) degan dasturga birlashtirilgan va ular uzluksiz ishlaydi.

C# da kod yozish oson bo'lishi uchun millionlab kutubxonalar tayyro holatda taqdim etiladi. Bundan tashqari koddagi xatolarni topuvchi, kodni testlovchi, debugging qiluvchi va boshqa bir nechta komponentlar mavjud. Bular hammasi birlashib .Net SDK ni tashkil qiladi.

SDK - Software Development Kit ya'ni dastur yaratish qutisi deyiladi.
         1) CLR

My reflections on Andela's EPIC values
Published: 2019-09-03 16:40:18

Andela is a network of software developers that is empowering and developing talented African software developers.

![Alt Text](https://thepracticaldev.s3.amazonaws.com/i/dbf1f39helyenen01lu6.png)

Usually, the word epic describes something too long like a heroic long poem, a long movie or a long book, but at Andela is a little different. The word EPIC stands for values that an Andelan must-have. They are the values that can help anyone to progress in developing his/her carrier.

![Alt Text](https://thepracticaldev.s3.amazonaws.com/i/l9cgw0trluorykzcesp8.png)

#EPIC
.**E** in **E**PIC stands for **Excellence**
Excellence is the quality of being outstanding and brighter. In epic for me being excellent is doing anything to its maximum. An excellent person helps others so that they can be excellent as well, and he/she is a good learn who is always seeking to improve and know something new.

.**P** in EPIC stands for **Passion**
Passion is a strong filling/liking for a subject or an activity. For me nothing does is good as doing something of your passion, that thing you like the most, the thing that you believe can change your life as well as the society. Hard work is a key to someone's own development, so without passion, things will become like a burden and this will be a failure.

.**I** in EPIC stands for **Integrity**
Integrity is the quality of being honest and having strong moral principles. Being honest is an important moral value that helps in the development of every person. Being honest will help me to know at what level I really am, and it will help me to construct a good and helping collaboration with my peers.

.**C** in EPIC stands for **Collaboration**
Collaboration is the act of working together with one or more people to achieve a common goal. Collaborating helps me to get knowledge from my peers and share what I know with others. This helps me also to understand better the concept of what I don't know well. Also, collaboration helps in creating a good relationship among peers.

By having EPIC values nothing seems impossible.
Security : CVE-2024-3094 unauthorized remote SSH access

Published: 2024-04-08 17:44:10

## Introduction
This article will be less technical as usual, as all you need to know about [CVE-2024-3094](https://nvd.nist.gov/vuln/detail/CVE-2024-3094) is described on [jFrog](https://jfrog.com/blog/xz-backdoor-attack-cve-2024-3094-all-you-need-to-know/) and [Y Combinator](https://news.ycombinator.com/item?id=39890817).

This backdoor is massive. Just to give you an idea, there are maybe 2-3 entities in the world capable of performing this activity, if it was a single person then maybe less than a thousand people in the world would have had a skill to perform the activity, even less than a hundred would dare to try and maybe less than ten would reach this point. Purely technically speaking the person behind is as professional as [Usain Bolt](https://en.wikipedia.org/wiki/Usain_Bolt) or [Taylor Swift](https://en.wikipedia.org/wiki/Taylor_Swift) in the respective domain. How to deal with a situation when you have an adversary that strong and there is a non zero probability that a villain has a different point of view on your personal well-being ?

## Security
The principles are somewhat evident, however sometimes you may be tempted to trade a short-term benefit over an somewhat illusionary guidelines : 

- you'll never walk alone : use stable releases of mainstream standard solutions, then you will have thousand eyes watching your back and maybe one of them will be [Andres Freund](https://twitter.com/AndresFreundTec), from the point of view of probability theory, if a chance to discover a backdoor by an engineer is `0.001` and there are `1000` engineers looking at the code then the probability to discover a backdoor is
`1 - (1-0.001)^1000 = 1 - 0.368 = 0.632 = 63.2%`
- "If you fail to plan, you are planning to fail!" (c) : have a plan of which software you intend to use and why, a recurrent problem is the questionable application of [fake it till you make it](https://en.wikipedia.org/wiki/Fake_it_till_you_make_it), you should have a plan and this plan should take into account the boundary conditions since day 0 
- limit the number of software you are using to remediate [the paradox of choice](https://en.wikipedia.org/wiki/The_Paradox_of_Choice) and to minimize the maintenance overhead
- apply the best [cybersecurity practices](https://en.wikipedia.org/wiki/Computer_security_software) : the keyword is `apply`
- have a professional available that knows how the things should be done : still valid in 2024, you have plenty of software providing all the possible insights with hundreds or thousand of alerts / warnings / updates, if you wish to have the business running there must be an expert onsite. ["Those who know.......know."](https://twitter.com/realjstatham/status/1700446807816311077)
- have a plan B when the plan A has failed : someday, and that day may never come, you did everything right and still failed, the best thing you can do is to be ready for this day and to plan the recovery

## Summary
Every happy ending is vanished rather fast from memory.

JavaScript Array Methods: Understanding `flatMap`
Tags: webdev, javascript
Published: 2024-04-08 17:21:45


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/f7y9zuwd2ukw6xh10lm2.png)

The `flatMap` method is a powerful tool in JavaScript that combines the functionality of both `map` and `flat`, allowing for the transformation and flattening of array elements in a single step. Let's delve into how this method works and explore its practical applications.

## Simple Example

Consider the following example that demonstrates the basic use of `flatMap`:

```jsx
const arr = [
  [1, 2],
  [3, 4],
  [5, 6],
].flatMap((n) => n)
console.log(arr) // [1, 2, 3, 4, 5, 6]
```

This method is particularly useful when we need both the mapping and flattening of an array, but why not just use `map` followed by `flat`? The answer lies in efficiency; `flatMap` is slightly more efficient than calling `map` and `flat` separately.

Moreover, `flatMap` can serve as a viable alternative to the `reduce` method in certain scenarios.

## Practical Application

Let's examine a more complex example involving an array of recent user orders, where each order includes details such as the date, total price, and a list of products:

```jsx
// Recent orders
const recentOrders = [
  {
    date: '06.04.2024',
    totalPrice: 18,
    products: [
      { name: 'milk', amount: 1, price: 6 },
      { name: 'fruits', amount: 4, price: 12 },
    ],
  },
  {
    date: '05.04.2024',
    totalPrice: 30,
    products: [
      { name: 'eggs', amount: 4, price: 20 },
      { name: 'apples', amount: 2, price: 10 },
    ],
  },
]
```

Our goal is to extract and display only the products from these recent orders. While this can be achieved using the `reduce` method, `flatMap` offers a more concise solution:

Using reduce:

```jsx
const recentProducts = recentOrders.reduce((acc, item) => {
  acc.push(...item.products)
  return acc
}, [])
console.log(recentProducts)
// Output:
// [
//   {name: 'milk', amount: 1, price: 6},
//   {name: 'fruits', amount: 4, price: 12},
//   {name: 'eggs', amount: 4, price: 20},
//   {name: 'apples', amount: 2, price: 10},
// ]
```

Using flatMap:

```jsx
const recentProducts = recentOrders.flatMap((item) => item.products)
console.log(recentProducts)
// Output:
// [
//   {name: 'milk', amount: 1, price: 6},
//   {name: 'fruits', amount: 4, price: 12},
//   {name: 'eggs', amount: 4, price: 20},
//   {name: 'apples', amount: 2, price: 10},
// ]
```

The `flatMap` approach is not only simpler but also enhances code readability.

In conclusion, for tasks requiring the straightforward combination of mapping and flattening, `flatMap` should be your go-to choice. For more complex transformations, consider sticking with the `reduce` method.

Object-Oriented Programming in Java: A Practical Guide 🚀☕
Tags: oop, java
Published: 2024-04-08 16:53:52

Object-Oriented Programming (OOP) is a fundamental paradigm that allows developers to create robust, modular, and maintainable software. In this article, we’ll explore the essential concepts of OOP using Java—a versatile language widely used in web development, Android apps, and enterprise solutions.


#1. What is OOP?
OOP stands for **Object-Oriented Programming**. Let’s break down its key components:

**Objects:** Objects are the building blocks of OOP. They encapsulate both **data** (attributes or properties) and **methods** (functions or behaviors). For example, a Car object might have attributes like make, model, and methods like `startEngine()` and accelerate().

**Classes:** A **class** serves as a blueprint for creating objects. It defines the structure and behavior of objects. Think of a class as a template. For instance, you can create multiple **Car** objects based on the same **Car** class.

#2. Key Concepts in OOP
Let’s delve deeper into essential OOP concepts:

##a. Encapsulation:
Encapsulation ensures that an object’s data (attributes) is hidden from external access. You achieve this by defining private fields and providing public methods (getters and setters) to interact with the data.

##b. Inheritance:
Inheritance allows you to create a new class (the subclass or derived class) based on an existing class (the superclass or base class). The subclass inherits the attributes and methods of the superclass. For instance, you can create a SportsCar class that inherits from the Car class.

##c. Polymorphism:
Polymorphism enables objects of different classes to be treated uniformly. It allows you to define methods with the same name but different implementations in different classes. For example, both Car and Bicycle classes might have a `move()` method, but their behavior differs.

#3. Putting OOP into Practice
Let’s create a simple example:

![OOP into Practice](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/apxzdcqxjk7fudaqon2d.png)

In this example:
We define a Car class with attributes (make and model) and a method (startEngine()).
In the Main class, we create a Car object and invoke its startEngine() method.

Remember, OOP is about modeling real-world entities, promoting code reusability, and organizing your code logically. As you explore more complex projects, these OOP principles will guide you toward elegant and efficient solutions. Happy coding! 🌟👩‍💻
