Augmented Assignment Operators
Tags: java, learning, programming, beginners
Published: 2024-04-24 15:32:00

The operators **+**, **-**, *****, **/**, and **%** can be combined with the assignment operator to form augmented operators. Very often the current value of a variable is used, modified, and then reassigned back to the same variable. For example, the following statement increases the variable **count** by **1**:

```
count = count + 1;
```
Java allows you to combine assignment and addition operators using an augmented (or compound) assignment operator. For example, the preceding statement can be written as

```
count += 1;

```
The **+=** is called the _addition assignment operator_. More are **-=**, ***=**, **/=**, and **%=**.
The augmented assignment operator is performed last after all the other operators in the expression are evaluated. For example,

```
x /= 4 + 5.5 * 1.5;

```
is same as

```
x = x / (4 + 5.5 * 1.5);
```
There are no spaces in the augmented assignment operators. For example, **+ =** should be **+=**

Like the assignment operator (**=**), the operators (**+=**, **-=**, ***=**, **/=**, **%=**) can be used to form an assignment statement as well as an expression. For example, in the following code, **x += 2** is a statement in the first line and an expression in the second line.

```
x += 2; // Statement
System.out.println(x += 2); // Expression
```

ECMA and ECMAScript: What You Need to Know
Tags: ecma, javascript, beginners
Published: 2024-04-24 15:14:13

## Everyone loves using it, but doesn't know much about it.🤔

Many people, whether new to the development field or with experience, have doubts and confusion around ECMA and ECMAScript.😵‍💫 In this article, we'll get it straight once and for all.😯

**Standardization in the Computer Industry:**

Standardization plays a significant role in the computer industry, helping to consume data prepared by other parties with minimum alteration. In 1960, computer manufacturers around Europe formed an association to draw up laws and rules. This association became the European Computer Manufacturers Association (ECMA) in 1961 and was later renamed to Ecma International – European Association for standardizing information and communication systems.

**ECMA Standards:**

Ecma International has developed more than 400 standards to facilitate and encourage the correct use of information and communication systems. Here is a snippet from Wiki that shows some ECMA international standards.

![ECMA international standards](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/x7ymm0u6yo66vq4hx68f.png)

**ECMA-262 and ECMAScript:**

Today we will talk about ECMA-262, which is the specification for ECMAScript, a scripting language used for client-side scripting and in server-side applications and services using different runtimes. The purpose of ECMAScript is to provide standardization for scripting languages like JavaScript to facilitate interoperability of webpages across the internet and different browsers.

**Multiple Editions of ECMAScript:**

Multiple editions of ECMAScript have been published, and each edition has brought tremendous additions to the standards. In a future article, we'll delve into ECMAScript 2015 (ES6) onwards.

**Conclusion:**

Now that you understand what ECMA stands for and what ECMAScript is, you'll be better equipped to navigate the development field. Thanks for your time! 😬

React Event Binding (JSX)
Published: 2024-04-24 15:09:34

**_Note _**-> Arrow function inside a class and function takes it's scope but the same arrow function inside an object will not take it's scope but the outermost function scope or the global scope(in case of global scope)


_<u>**Class Component**</u>_

**_Constructor Binding_** ->

```JS
import React from "react";

class BindHandler extends React.Component {
  constructor() {
    super();
    this.state = {
      count: 0,
    };
    this.decrementCount = this.decrementCount.bind(this);
  }
decrementCount() {
    this.setState({ count: this.state.count - 1 });
  }
render() {
    return (
      <>
        <h1>{this.state.count}</h1>
        <button onClick={this.decrementCount}>Decrement</button>
      </>
    );
  }
}
export default BindHandler;
```

**_Arrow Function Binding_** where the function itself is Arrow function ->
Note that we don't need any constructor binding here as arrow function always takes the scope of the outer function.

```JS
import React from "react";

class BindHandler extends React.Component {
  constructor() {
    super();
    this.state = {
      count: 0,
    };
  }

  incrementCount = () => {
    this.setState({ count: this.state.count + 1 });
  };
  render() {
    return (
      <>
        <h1>{this.state.count}</h1>
        <button onClick={this.incrementCount}>Increment</button>
      </>
    );
  }
}

export default BindHandler;
```

**_Normal Function_** -> converted to arrow function ->

```JS
import React from "react";

class BindHandler extends React.Component {
  constructor() {
    super();
    this.state = {
      count: 0,
    };
  }

  decrementCount() {
    this.setState({ count: this.state.count - 1 });
  }
  render() {
    return (
      <>
        <h1>{this.state.count}</h1>
        <button onClick={() => this.decrementCount()}>Decrement</button>
      </>
    );
  }
}

export default BindHandler;
```
Adjusted R2
Published: 2024-04-24 14:59:30

Adjusted R2, çoklu regresyon modellerinde kullanılan bir istatistiktir(polinomal regresyon da çoklu regresyon modelidir. çoklu linear regresyon ile karıştırmayın). Standart R2 skoru, modele eklenen her yeni özelliğin (bağımsız değişkenin) modelin açıkladığı varyansı artıracağını varsayar. Ancak, bazı durumlarda, rastgele gürültüyü modellemek için gereksiz özellikler eklemek modelin genelleme yeteneğini azaltabilir. Bu nedenle, gereksiz özelliklerin eklenmesiyle ilgili bu potansiyel sorunları dikkate almak için Adjusted R2 kullanılır.

Adjusted R2, modeldeki özellik sayısını dikkate alarak R2 skorunu düzeltir. Özellikle, Adjusted R2 skoru, modeldeki özellik sayısı arttıkça azalır (eğer yeni özellikler önemli bir şekilde modelin performansını artırmıyorsa). Bu nedenle, Adjusted R2 genellikle modelin karmaşıklığını kontrol etmek için kullanılır.

Adjusted R2'nin hesaplama formülü aşağıdaki gibidir:



![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/5jb3q84bymdwl9aanxch.png)





Burada:

n, örneklemin boyutudur (veri noktalarının sayısı),
p, bağımsız değişkenlerin (özelliklerin) sayısıdır.
Bu formül ile Adjusted R2, modeldeki özellik sayısını dikkate alır ve böylece modelin genelleme yeteneğini daha doğru bir şekilde ölçer.



Bir başka açıklama ise şu şekilde 

Düzeltilmiş R-kare, regresyon analizinde modelin performansını değerlendirmek için kullanılan istatistiksel bir ölçüdür. Klasik R-kare ölçütünün bazı problemleri vardır ve düzeltilmiş R-kare bu sorunları gidermek amacıyla kullanılır.

İşte düzeltilmiş R-kare hakkında daha fazla bilgi:

- 
Klasik R-kare Sorunları:
Klasik R-kare, bağımsız değişken sayısının artmasıyla her zaman artar. Ancak bu, modelin performansını yanıltıcı bir şekilde artırabilir.
Model ile ilişkisiz olan değişkenlerin R-kareyi sahte bir biçimde artırmasına yol açar.

- 
Düzeltilmiş R-kare:
Düzeltilmiş R-kare, klasik R-kareyi cezalandırarak elde edilir.
Modeldeki bağımsız değişken sayısı ve gözlem sayısı göz önüne alınarak hesaplanır.
Modelde yer alan değişken sayısı ve gözlem sayısı göz önüne alınarak cezalandırma yapılır.
Düzeltilmiş R-kare, farklı değişken ve gözlem sayılarına sahip modellerin performansını karşılaştırmak için kullanılır.

Tips for Overwhelmed Devs
Published: 2024-04-24 14:48:46

[Full disclosure: I'm a DevOps consultant]

DevOps-type tasks tend to be quite different from traditional Feature-oriented tasks:
* feature = "stateless", you are given e.g. a database and other services, and write code to implement a feature
* devops = "stateful": write Terraform or other code to create and manage resources, ex a database. A challenge is that there's *hundreds* of types of resources, the interaction can be complex, and each one is slow to build. It's really easy to leave old resources around, costing money or creating confusion.

On the other hand, the Business operates at the speed of the deployment pipeline. The speed and quality of the tests (CI) matters to the Feature devs, so they can get their work done. At the end of the day the code needs to land in Production or the Business doesn't get any value. **Features don't matter until they're in front of the Users!**

## Tips

- find other people in the company, to learn from each other
as a team, swarm to fix team-level issues
- weekly: write down team-level pain points, communicate to management
- focus on *trust* over *speed* -- it doesn't matter if a test ran in one second if the results aren't *actionable*
- consider using a more Dev-friendly way to manage resources: ex Pulumi let you write in Typescript or Python to build and manage resources (databases, networks, buckets)

Feel free to <a mailto="johntellsall@proton.me">contact me</a>, there are other ways you and your team can streamline your work and deliver features faster.

Disadvantage of r2 method
Published: 2024-04-24 14:39:15

R2 skorunun birkaç dezavantajı vardır:

Aşırı Uyum: R2 skoru, modelin aşırı uyumlu olup olmadığını belirlemek için kullanılamaz. Yani, model eğitim verilerine çok iyi uyuyor ancak yeni verilere iyi genelleme yapamıyorsa, R2 skoru hala yüksek olabilir. Bu durumda, modelin performansını doğru bir şekilde değerlendirmek için başka metriklerin (örneğin, çapraz doğrulama skorları) kullanılması gerekebilir.

Tahmin Edilemezlik: R2 skoru, modelin tahminlerinin ne kadar güvenilir olduğunu belirlemek için kullanılamaz. Yani, modelin tahminleri büyük bir hata ile ilişkilendirilebiliyorsa (yani, tahminler genellikle doğru olsa bile), R2 skoru hala yüksek olabilir.

Bağımlı Değişkenin Ölçeği: R2 skoru, bağımlı değişkenin ölçeğine bağlıdır. Yani, bağımlı değişkeni dönüştürürseniz (örneğin, logaritmik dönüşüm uygularsanız), R2 skoru değişebilir.

Bağımlılıklar: R2 skoru, bağımsız değişkenler arasındaki bağımlılıkları dikkate almaz. Yani, bazı bağımsız değişkenler diğerlerine bağlıysa, R2 skoru hala yüksek olabilir, ancak bu durumda modelin performansını doğru bir şekilde değerlendirmek için başka metriklerin kullanılması gerekebilir.

Kısaca R2 yonteminin de eksikliklerinin olduğunu unutmamamız gerekir.
Unity XScaling - A library for Realtime Texture and Rendering Upscaling (Super-Resolution)
Tags: unity3d, opensource, asset, howto
Published: 2024-04-24 14:29:12

**Hey, everybody**. I recently finished the first version of a library for real-time upscaling (texture enhancement). **Unity XScaling Framework** - is a set of tools for texture upscaling and real-time camera rendering, allowing you to improve picture quality without increasing the size of your build.

Simply load 256x256 textures into your build and upscale them to any size in real time on demand. Or increase performance and quality with Super-Resolution Rendering and the Camera Upscale component

![Unity XScaling](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/lyrc1fpo58qods2ua985.png)

**❓ What does the XScaling Library include?**
* Real-time Texture Upscaling;
* UI Image and RawImage Upscaler;
* Distance-based textures upscaling;
* Rendering Upscaling (Super-Sampling) (similar FRS or DLSS but fully cross-platform);
* GPU-Based and cross-platform;

## Get Started
**Unity XScaling** installs into your project as easily as possible - basic installation and configuration takes **only 4 steps**.

**Basic Installation:**
* Download [Latest Release from GitHUB](https://github.com/DevsDaddy/UnityXScaling/releases);
* Import **.unitypackage** into your project;
* See example scenes or add ready-to-use components on your models / ui elements;
* Done!
    

**Dependencies:**
* Unity 2019+ and Built-in Render Pipeline Only (URP and HDRP support is coming soon);
* TextMesh Pro and Texture2D packages for UI support;
    

## Note
> This library is still under development. The system performs best on cartoon textures, but I aim to solve this soon by adding new algorithms such as Real-ESRGAN. Do not use preset HQ Quality at Production. Use HQ Performance instead.

**And of course thank you for reading, I would be happy to discuss various upscaling algorithms and work together!**

Naming Conventions
Tags: learning, java, beginners, programming
Published: 2024-04-24 14:26:45

Sticking with the Java naming conventions makes your programs easy to read and avoids errors. Make sure that you choose descriptive names with straightforward meanings for the variables, constants, classes, and methods in your program. As mentioned earlier, names are case sensitive. Listed below are the conventions for naming variables, methods, and classes.

- Use lowercase for variables and methods. If a name consists of several words, concatenate them into one, making the first word lowercase and capitalizing the first letter of each subsequent word—for example, the variables **radius** and **area** and the method **print**.
- Capitalize the first letter of each word in a class name—for example, the class names **ComputeArea** and **System**.
- Capitalize every letter in a constant, and use underscores between words—for example, the constants **PI** and **MAX_VALUE**.

It is important to follow the naming conventions to make your programs easy to read. Do not choose class names that are already used in the Java library. For example, since the **System** class is defined in Java, you should not name your class **System**.
Named Constants
Tags: java, learning, programming, beginners
Published: 2024-04-24 14:23:41

A named constant is an identifier that represents a permanent value. The value of a variable may change during the execution of a program, but a named constant, or simply constant, represents permanent data that never changes. For example, pie of a circle is a constant. If you use it frequently, you don’t want to keep typing **3.14159**; instead, you can declare a constant for pie. Here is the syntax for declaring a constant:

```
final datatype CONSTANTNAME = value;

```
A constant must be declared and initialized in the same statement. The word **final** is a Java keyword for declaring a constant.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/04wc0co372zezgc4oc9n.png)

There are three benefits of using constants: 

- you don’t have to repeatedly type the same value if it is used multiple times; 
- if you have to change the constant value (e.g., from **3.14** to **3.14159** for **PI**), you need to change it only in a single location in the source code; 
- a descriptive name for a constant makes the program easy to read.
