C# dasturlash tilida kasrlar
Tags: csharp, beginners
Published: 2024-04-18 11:53:17

## Kasr son -- bu verguldan so'ng 0 yoki unda ko'proq boshqa raqamlar bilan ifodalanadigon sonlar hisoblanadi. 

> Masalan:
```
{1.1, 2.2, 3.14159}
```
C# dasturlash tilida kasrlar "double" yoki "float" kabi ko'paytiriladigan sonlar uchun ishlatiladi. Kichik kasr sonlar uchun esa "decimal" ma'lumot turi ishlatiladi.

1.float --- Bu, 32-bitlik  ma'lumot turi. Uni foydalanish bilan oqilona (memory-efficient) amalga oshirish mumkin, lekin bu yuqori to'g'rilik darajasiga ega emas.Bu ~6~9 xona aniqlikda chiqaradi.


2.double --- Bu, 64-bitlik  ma'lumot turi. U float dan kengroq diapazon va to'g'rilik darajasiga ega bo'lgan ularning butun sonlari va o'nlik sonlarida ishlov berish uchun keng o'lchamli ma'lumot turi.
Bu ~15~17 xona aniqlikda chiqaradi.

3.decimal --- Bu, 128-bitlik ma'lumot turi. U barcha sonlar uchun eng yaxshi to'g'riylikni ta'minlaydi. Bu, pul miqdorlari, dastlabki qiymatlari va boshqa hisob-kitob amaliyotlar uchun keng tarqalgan.**
Bu ~28~29 xona aniqlikda chiqaradi.

------------------------------------------------------------------

> Masalan:

```
double d = 3.14; // Ko'paytiriladigan son
float f = 2.718f; // Ko'paytiriladigan son
decimal dec = 123.456m; // Kichik kasr son
```
Shuningdek, matematik amallar yoki mantiqiy operatsiyalarda kasr sonlardan foydalaniladi.
------------------------------------------------------------------

```
float floatValue = 3.14f; // float uchun "f" postfixi kerak
double doubleValue = 3.14; // double default o'lchamda ko'rsatiladi
decimal decimalValue = 3.14m; // decimal uchun "m" postfixi kerak 
```
-----------------------------------------------------------------

> Masalan:

```
double a = 17.5;

```

```
double b = 3.5;
double c = a / b; // Bo'lib ko'paytirish
```
` 
Bu misolda c o'zgaruvchisi qiymati 5 ga teng bo'ladi.`
------------------------------------------------------------------

- Har bir ma'lumot turi o'z xususiyatlari, diapazoni, va ishlash xususiyatlari bor. Shuningdek, hisob-kitob operatsiyalari paydo bo'lishi mumkin. 

> Masalan:

```
float a = 1.234f;
float b = 5.678f;
float sum = a + b;
Console.WriteLine(sum); // 7.912

double x = 1234.567;
double y = 8910.1112;
double product = x * y;
Console.WriteLine(product); // 11005412.0181404

decimal price1 = 12.50m;
decimal price2 = 7.80m;
decimal total = price1 + price2;
Console.WriteLine(total); // 20.30
```

- `Diqqat qilish kerakki, float va double sonlarining hisob-kitob operatsiyalari amalga oshirishda aksariyatida nuqta ishlatiladi, lekin decimal sonlarida bu shaklda amalga oshirilmaydi. Ma'lumot turlarini tanlash paydo bo'lganda, xotiradagi o'lchami, to'g'rilik darajasi va dastlabki qiymatlari to'g'ri tanlash juda muhimdir.`
From HDDs to Hypercars: How Technology is Breaking Through Bottlenecks
Tags: technology, storage, ai, performance
Published: 2024-04-18 11:49:26

Just a few years ago, 10,000 IOPS (Input/Output Operations Per Second) seemed like the pinnacle of storage system performance. Back then, the whirring of hard disk drives (HDD) was a familiar sound. Solid-state drives (SSDs) offered a leap forward in read/write speeds and lower power consumption, but they were held back by a bottleneck: the disk access protocol. The SATA protocol, designed for the sequential access patterns of HDDs, couldn't unleash the full potential of SSDs.

The introduction of the Non-Volatile Memory Express (NVMe) protocol revolutionised storage performance. NVMe leverages the parallel processing capabilities of SSDs to deliver significantly lower latency and much higher bandwidth. By supporting tens of thousands of parallel commands to the storage device, NVMe unlocks unprecedented speed and throughput. Additionally, it takes advantage of multi-core processors, faster memory designs, and improved data access commands. This development is instrumental in advancements within software engineering fields like Artificial Intelligence (AI) and Machine Learning (ML), where high-performance storage is critical.

Just like storage systems, cars are breaking free from the limitations imposed by legacy design methods. Recent electric car launches by EV companies showcase this trend. These vehicles boast performance metrics that shatter previous limits, pushing the boundaries of speed, and efficiency and outclassing comparable gasoline-powered models in the process.

Imagine a world where cars safely move at the speed of light! New technologies may one day push us closer to that dream.
An Overview and Brief Explanation of Direct Preference Optimization (DPO)
Tags: dpo, ai, machinelearning
Published: 2024-04-18 11:45:52

Direct Preference Optimization (DPO) is fundamentally a streamlined approach for fine-tuning substantial language models such as Mixtral 8x7b, Llama2, and even GPT4. It’s useful because it cuts down on the complexity and resources needed compared to traditional methods. It makes the process of training language models more direct and efficient by using preference data to guide the model’s learning, bypassing the need for creating a separate reward model.

Imagine you’re teaching someone how to cook a complex dish. The traditional method, like Reinforcement Learning from Human Feedback (RLHF), is like giving them a detailed recipe book, asking them to try different recipes, and then refining their cooking based on feedback from a panel of food critics. It’s thorough but time-consuming and requires a lot of trial and error.

title: Kilua - new Kotlin/Wasm web framework
published: true
description: .
tags: kilua,kotlin,webassembly,compose
---

I have published [Kilua](https://github.com/rjaros/kilua) 0.0.1 - the first public release of my new compose powered web framework for Kotlin/Wasm and Kotlin/JS.

Kilua allows you to:

- Use powerful Compose programming model and state management to develop web applications.
- Compile the same application code for Kotlin/Wasm and Kotlin/JS targets.
- Create fullstack applications with companion [Kilua RPC](https://github.com/rjaros/kilua-rpc) library.
- Deploy your application with full SSR (Server Side Rendering) for better SEO performance and user experience.

Kilua is similar to [compose-html](https://github.com/JetBrains/compose-multiplatform#compose-html), but it has considerable advantages:

- Webassembly support
- Server Side Rendering
- a lot of ready to use components
- fullstack RPC with fullstack UI components
- i18n support with gettext
- imperative API layer to directly interact with UI components

If you want to see how to write Kilua applications, you can find fully compatible [TodoMVC](https://todomvc.com/) and [RealWorld](https://github.com/gothinkster/realworld) example applications, alongside other demo apps in the [examples](https://github.com/rjaros/kilua/tree/main/examples) directory.

Understanding Java Exceptions: A Guide with Practical Examples
Tags: java, code, programming, tutorial
Published: 2024-04-18 10:49:46

Java, one of the most widely used programming languages, is renowned for its robust exception handling mechanism. Exception handling is a critical concept in Java that allows a programmer to handle runtime errors, thus ensuring the smooth execution of the application.
**What is an Exception in Java?**
An exception is an event that disrupts the normal flow of the program. It is an object which is thrown at runtime and may be caught by catch blocks. If not properly handled, it can cause your program to terminate abruptly.

**Types of Exceptions**
There are two main categories of exceptions in Java:

- **Checked Exceptions:** These are exceptions that are checked at compile-time. It’s mandatory for a programmer to handle these exceptions. For example, IOException, ClassNotFoundException, etc.
- **Unchecked Exceptions:** These are exceptions that are not checked at compile-time. They occur mainly due to programming errors, such as NullPointerException, ArrayIndexOutOfBoundsException, etc.

**Exception Handling Mechanism**
The core of Java’s exception handling lies in three keywords: `try`, `catch`, and `finally`.

- `try`: The block of code that might throw an exception.
- `catch`: The block of code that handles the exception.
- `finally`: A block that gets executed whether or not an exception has occurred.

#Code Snippets and Examples
Let’s look at some examples to understand how to handle exceptions in Java.
##Example 1: Handling ArithmeticException
![Handling Arithmetic Exception](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/u0ovas33xrigwg0cq4yr.png)
In this example, dividing by zero would cause an `ArithmeticException`. The `catch` block catches the exception and prints an error message.

##Example 2: Handling NullPointerException
![Handling NullPointerException](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/utdpnq2iedtou06ba3yj.png)
Attempting to call a method on a null reference throws a `NullPointerException`, which is then caught and handled.

**Best Practices**
When working with exceptions, it’s important to follow best practices:

- Catch specific exceptions instead of a generic exception.
- Avoid empty catch blocks.
- Use finally blocks for cleanup code.
- Throw exceptions with meaningful messages.

#Conclusion
Exception handling in Java is a powerful mechanism that not only helps in dealing with runtime errors but also improves the reliability of the application. By understanding and implementing proper exception handling, developers can ensure that their Java applications are robust and fault-tolerant.
I need a design for a Credit-based Course Registration System
Tags: architecture, webdev, java, react
Published: 2024-04-18 10:44:36

I need a design architecture for a website for registering for credit-based courses for students. 
Descript:
Each semester, students can register for a maximum of 30 credits (approximately 9-10 courses). Courses can be mandatory or elective, and may have one or more prerequisite courses (if a prerequisite course has not been completed, the student cannot register for the subsequent course).

On the registration opening time, students will log into the system and see a list of courses they can register for. They will select the courses and proceed with registration. If classes are full, students will be placed on a waiting list for the university to consider opening additional classes. If no extra classes are opened, the student's registration for that course will be canceled.

After successful registration, an email confirmation will be sent to the student, including details of the registration and tuition fee payment decision.

Additionally, the system will allow students to view their academic information (such as earned credits, courses taken, course grades, cumulative GPA), weekly schedules, and other utilities.

Once the required credits for each major are fulfilled, students have the right to apply for graduation. If all criteria are met, students will be awarded their degree and listed among the university's alumni. Degree information will be publicly available on the university's website. Alumni information will be retained for tracking career progression (with the consent of the student), conducting surveys, and other activities.

I need a schematic design of the server-client connection method and the reasons for choosing that particular style/pattern, as well as how to store the database.

For example, a system may have multiple servers, with each server handling 4-12 APIs for specific tasks to reduce congestion if there are many users accessing the system. Alternatively, some servers may only allow reading data from views, while updating data requires access from another server with direct access to the tables.

A major issue with the credit registration system is that on the registration opening day, there is a high influx of users, leading to system errors or slowdowns, while on regular days, there are fewer users accessing the system. How can I address this issue?

Where I can seek advice or find schematic designs, class diagrams, document for similar systems?
