Title: Effective Error Handling Strategies in Java
Published: 2024-04-11 18:35:58

#Introduction:
Error handling is a crucial aspect of Java development, ensuring that applications gracefully handle unexpected situations and maintain robustness. In this article, we'll explore some effective error handling strategies in Java, covering best practices, common pitfalls to avoid, and practical code examples.

#1. Use Exception Handling:
Java's exception handling mechanism allows developers to gracefully handle errors and exceptions. It's essential to use try-catch blocks to catch exceptions and handle them appropriately. Here's an example:

#2. Follow the Principle of Fail Fast:
When encountering errors or invalid inputs, it's advisable to fail fast by throwing exceptions immediately. This approach helps in identifying and resolving issues early in the development process. Here's an example:

#3. Logging and Monitoring:
Implement robust logging and monitoring mechanisms to record error details, stack traces, and other relevant information. Utilize logging frameworks like Log4j or java.util.logging for comprehensive error logging. Example:
![Code Snippet](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hy3io5e34t0k4b0zfuwl.png)

#4. Define Custom Exceptions:
For domain-specific errors, define custom exception classes to provide meaningful error messages and encapsulate specific error conditions. Example:
![Code Snippet](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/yjuatd1icv48e1yfaims.png)

#5. Graceful Error Handling in Web Applications:
In web applications, implement global exception handling mechanisms to centralize error handling logic and provide consistent error responses to clients. Example (Spring MVC):
![Code Snippet](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nis5078zbdusp2alh8oo.png)

#Conclusion:
Effective error handling is essential for building robust and reliable Java applications. By following best practices such as using exception handling, failing fast, logging errors, defining custom exceptions, and implementing global error handling mechanisms, developers can ensure that their Java applications gracefully handle errors and maintain stability.

#Note:
Remember to adapt these strategies to your specific application requirements and consider additional factors such as performance and security when implementing error handling logic.

🚀 **Today's Learning:**

🌟 DSA

- Insert Node at beginning of Linked List
- Delete Last Node of Linked List

🌟 Dev

- Agile Methodologies
- Git branching

🔍 **Some Key Highlights:**

DSA

Insert Node at beginning of Linked List - Create a new node (say newNode). Make newNode → next point to head. Make head point to newNode (as this is the new head). T.C & S.C → O(1)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kx449ehmey1jqo55lqyo.png)

Delete Last Node of Linked List

Move to the second last node and make it null. Also delete the last node (only in C++. In python, Java and JavaScript this need not be done as this is done automatically by garbage collectors). Also check for empty list or just one node. Return null in this case.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/a8a58kleyzgdvkmglugu.png)

DEV

1. **git branch -vv:**
    - This command lists all local branches along with extra information.
    - **`vv`** stands for "verbose" and "verbose", which provides more detailed information about each branch.
    - Specifically, it shows the name of each branch, the commit it points to, and whether the branch is tracking a remote branch.
2. **git branch -vv -a:**
    - This command lists both local and remote branches, along with additional information.
    - **`a`** stands for "all", which includes remote branches in addition to local branches.
    - So, this command provides a comprehensive view of all branches in the repository, both local and remote, along with detailed information about each branch, such as the commit it points to and whether it's tracking a remote branch.

🔐Simple Yet Crucial step to avoid security incidents💡
Tags: security, beginners, devops, gitlab
Published: 2024-04-11 18:15:45

Recently I’ve experienced a GitLab security incident. 
Had a pretty new GitLab version (~2 months old), but there were a few security patches released. Apparently, I was missing one of them.

I noticed GitLab throwing 500 errors randomly and later 502 consistently. Looking at the server I’ve noticed some processes run by “git” user, which shouldn't be running, consuming all CPU. Processes were restarting after killing them. Updating GitLab to the newest version resolved the issue.

Keeping software up-to-date can sometimes be a cumbersome process. But security incidents in sensitive systems can be very costly. Luckily, this time it wasn’t the case. I hope this reminder will save others from uncomfortable situations.
Kraken market - the main marketplace of the dark network
Published: 2024-04-11 17:44:03

A Kraken site, also known as a deep web site or darknet  site, is an online platform that is not indexed by standard search  engines. These sites exist on networks such as provide a high level of  privacy and anonymity. They are often used by journalists, activists,  and others who require a secure space to exchange information. Accessing  hidden sites requires special software, such as the Tor browser.  Despite the negative reputation associated with illegal activity, Kraken  market also have legitimate uses and provide important opportunities  for protecting freedom of speech and privacy. They can be a valuable  tool for individuals seeking to communicate and share information in a  secure and anonymous manner. However, it is important to use hidden  sites responsibly and in accordance with the law.

Upload File di Node JS
Tags: node, webdev, file, upload
Published: 2024-04-11 18:04:08

**Apa itu Node JS?**
Node JS merupakan run time environment pada javascript yang didesain untuk membuat aplikasi website menggunakan bahasa pemrograman javascript. Pada jaman dahulu javascript dikenal sebagai bahasa pemrograman yang berjalan di sisi client, namun sekarang javascript dapat berjalan di sisi server

Apa saja yang akan kita butuhkan?

1. Node JS
2. Package Manager (npm, yarn, etc)
3. Text editor
4. Formidable

**Step 1**
Install package formidable

```bash
npm install formidable
```

**Step 2**
Buat form.html di dalam folder project node js. Form ini akan digunakan untuk field upload file

```html
<form action="upload" method="post" enctype="multipart/form-data">
  <input type="file" name="file">
  <input type="submit">
</form>
```

**Step 3**
Buat server.js yang akan menjadi server untuk upload file

```js
const http = require('http')
const formidable = require('formidable')
const fs = require('fs')

const server = http.createServer((req, res) => {
  if(req.url == '/upload') {
    const form = new formidable.IncomingForm()
    form.parse(req, (err, fields, files) => {
      const oldPath = files.file.path
      const newPath = './files/'+files.file.name
      fs.rename(oldPath, newPath, (err) => {
        if(err) throw err
        res.write('File uploaded')
        res.end()
      })
    })
  } else {
    fs.readFile('./form.html', 'utf8', (err, data) => {
      if(err) throw err
      res.writeHead(200, {'Content-Type': 'text/html'})
      res.write(data)
      res.end()
    })
  }
})

server.listen(8080, () => {
  console.log('server running at 8080')
})
```

yang terakhir jangan lupa untuk membuat folder file yang digunakan untuk menyimpan file yang telah diupload

A robust solution for managing and resolving conflicts in NuGet package dependencies within Visual Studio
Published: 2024-04-11 17:29:28

Today I got a project in .net core for upgrading the version from .net 6 to 8 and I was super excited but when I set up the project on my system, I found the complexity of the project.

There are 8-10 projects and references to each other’s. I started to work on upgradation. I was happy because I had done my job (.Net 6 to 8) but when I built the project then lots of errors are there regarding conflicts of dependencies,


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ukt62p1hzdiqipyf8pxr.png)

So, I started to resolve it one by one but when I built the project again then errors of conflict increased more. I spent much more time to resolve the issues but not succeed then I found [NuGetSolver](https://marketplace.visualstudio.com/items?itemName=vsext.NuGetSolver) to resolve this issue. I downloaded the extension from VS Marketplace. [NuGetSolver](https://marketplace.visualstudio.com/items?itemName=vsext.NuGetSolver) is a powerful Visual Studio extension designed to help you tackle NuGet dependency conflicts with ease.

I run the tool from the “Solution Explorer” by right-clicking and selecting “Resolve Dependency Conflicts”.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fk36x1qoo990ktsnqskx.png)

You can run the tool even if your solution doesn’t have any dependency conflicts at the moment. It will upgrade your dependencies while keeping the changes minimal.

Writing a bootloader: learnings
Tags: kernel, bootloader, c
Published: 2024-04-11 17:27:59

1. The instruction pointer of the CPU, on boot, is hardcoded to the value 0xFFFFFFF0 i.e. the last 16 bytes of the 32-bit address space. 

2. On boot, the BIOS copies itself to some address in memory.
So, the address contains 0xFFFFFFF0 contains a jump instruction to the place in memory where the BIOS has copied itself.

3. Once the BIOS is loaded, it goes through the list of devices to check which are bootable: by checking the bytes 511 and 512 of the first sector of each device. If the value of those bytes is 0xAA55, that device is bootable.

4. Once a bootable device is found, copy the contents of the device's first sector into memory to the address 0x7c00. This address now contains the bootloader. Jump to this address and execute the code. The bootloader then loads the kernel at 0x100000.

Fun facts:
1. All x86 processors begin in a 16-bit mode called real mode. The bootloader switches to 32-bit protected mode by setting the lowest bit of CR0 register to 1.

2. 0xb8000 is the start of video memory. This memory supports 25 lines, each line contains 80 ASCII characters. Each element here is of 2 bytes (1 byte for the ASCII character, 1 byte is the attribute byte like color). So, we can set the color of each character we want to display by writing bytes starting from this address.

Learning AWS Day by Day — Day 34 — CloudFormation
Tags: aws, cloud, cloudcomputing, beginners
Published: 2024-04-11 17:23:56

Exploring AWS !!

**Day 34:**

**CloudFormation: IaC (Infrastructure as Code)**


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/rr71cfv3gntikoj334mg.png)

Instead of creating multiple instances, databases and other resources manually, we can create a single piece of code which can be used to create multiple infrastructures. CloudFormation not only creates resource on AWS account but also waits for them to stabilize while they start. It verifies failure, then it can gracefully roll infrastructure back to a past known good state.

CloudFormation allows us to model our entire infrastructure in file. We can create or modify an existing AWS CloudFormation template. A template describes all of our resources and preparation. To make changes or modify, we can simply track the differences in our templates to check changes in our infrastructure, similar to way the developers control revisions to source code. We can also reuse our template to set up our resources consistently and repeatedly. We can just describe our resource once and then provision the same resource over and over to multiple regions.

Top Features: Authoring with JSON/YAML, Authoring with familiar programming languages, safety controls, preview changes to our environment.

Concepts:

Template: Its JSON or YAML formatted file, saved as .json, .yaml, and .template. We can specify multiple resources in single template and configuration for these resources to work together.
Stacks: We can manage related resource as single unit called stack. We can also delete entire architect by deleting stack. We can work with stack by using AWS CloudFormation console, API or AWS CLI.
Change Sets: To change the running resource, we need to update stack. We can generate a change set, which is a summary of our proposed changes. If we generate change set, we can see how our changes will cause our database to be replaced, and we will be able to plan accordingly.

How does CloudFormation work?

— Code infrastructure from scratch or use available template.
— Code locally or upload into S3 bucket.
— Use AWS CloudFormation via GUI or CLI to create a stack based on our template.
— AWS CloudFormation provisions and config resources we specified on our template.

CloudFormation Templates:

We can use AWS CloudFormation Designer or any other text editor.
CloudFormation supports:
JSON — ECMA-404, JSON Std.
YAML — Version 1.1

CloudFormation Designer:
Graphic tool for creating, viewing and modifying AWS CloudFormation templates. We can design our template resources by drag and drop and then edit.
Reusable Modal Component using React Portals
Tags: webdev, tutorial, react, javascript
Published: 2024-04-11 16:43:59



## How to create a reusable modal component from scratch

By the end of this tutorial, we will have a modal component that can be used anywhere in a React Application. We can create a modal just by passing the children to the component.

[CodeSandbox Implementation](https://codesandbox.io/p/sandbox/adoring-dew-86v8kl)


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/4qmfzdkk6zkxw58tbzq6.gif)

## React Portal

They’re cool for rendering UI outside of your current components. We are making a Modal component that shows a message to the user . It should always show up centered in the window. We put the portal higher up in the DOM outside of all out layouts, and render the modal component into it. Then when we want to use it, we just render a <Modal /> passing the message UI as a prop.


## Creating the Modal Component

In `index.html` create a div with id `modal`, besides the root div. This is where we will render the modal.

### Modal Styling
For basic styling, we'll define some CSS rules. The #modal div will serve as the container for our modal content.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/327z1wex9ttj267eig9i.png)

Create Modal.tsx file for the component. Write the boilerplate and props for the component.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pom1gp6o1cytwov1947m.png)

We render the children in #modal div using `document.getElementById("modal")`. 

Using `createPortal` function we can pass the children and the Ref as arguments. So any children will get rendered inside the Modal Div using Ref. Thus we have a reusable component that can take in React Chiukldren and render as our modal.

`return <>{createPortal(children, elRef?.current)}</>;`

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/pkn540zmrepb8py7gmwi.png)


To close the modal, we listen to all clicks and toggle the state if it's outside the child.
To avoid memory leaks, we have to return a cleanup function and remove our event listener for closing the modal.

## Usage of Modal Component

You can import the modal component and create a Boolean State to open and close the Modal. Pass the children, state and closeModal function to the component. The component will mount the children inside the #modal id div.

How Independent is OpenAI from Microsoft?
Tags: chatgpt, openai, microsoft, search
Published: 2024-04-11 16:34:51

Sam Altman, the CEO of OpenAI, has stated that his company is independent and not controlled by Microsoft. Despite this claim, Microsoft appears to be fully leveraging the capabilities of ChatGPT across its product lineup, particularly within its Bing search engine. While Microsoft is integrating ChatGPT extensively, OpenAI seems hesitant or slow in monetizing and commercializing the technology directly.

There’s potential for OpenAI to disrupt the search engine market significantly if they chose to launch a dedicated product like gptsearch.com, which would combine ChatGPT with web search capabilities. Such a move could potentially shift market dynamics in just a week. However, from current observations, it appears that OpenAI has prioritized enabling Microsoft to commercialize ChatGPT first. This approach raises questions about whether OpenAI makes decisions independently from Microsoft or if there are underlying agreements or pressures that guide their strategies.
