Tailwind Css Vs Bootstrap
Tags: dev2
Published: 2024-07-04 12:43:31

**Tailwind css vs Bootstrap**
In the fast growing and ever-changing world of technologies, choosing the right tools and technologies is very pertinent to the performance, customization and development of an application. In frontend Development, design and responsiveness Is very important. Amongst the numerous technologies, tailwind css and  Bootstrap have emerged as two of the most popular choices. Both technologies aim to improve the process of building responsive, visually appealing websites although they have different approaches and unique features. In this article, we will compare Tailwind css and Bootstrap and exploring their differences.

**Tailwind Css**
Tailwind CSS is a Utility-first CSS framework for building rapid custom UI. Tailwind CSS is all about giving you these utility classes for things like colors, spacing, and how text looks. This means you can mix and match them to make your web page look just right.
It is a highly customizable, you can change how Tailwind CSS works to fit your needs. This includes changing the color scheme, the fonts, and more right in the settings.
Tailwind is also a low-level CSS framework that gives you all of the building blocks that you need. Also, it is a cool way to write inline styling and achieve an awesome interface without writing a single line of your own CSS.

**Bootstrap**
Bootstrap was made by some folks at Twitter in 2011 and is a free tool that makes building websites faster and easier. It's prevalent among people who make websites because it has a bunch of ready-made parts you can use
It has its system with 12 columns that change size based on how big the screen is, making it great for viewing on phones, tablets, and computers.
It comes with lots of ready-to-use pieces like menus, buttons, and alerts. You can change how these look with some coding skills.
Bootstrap is made to be mobile-friendly from the start and works well in different web browsers. This means websites built with Bootstrap look good on any device.
You can easily change the look of your site with Bootstrap's theme system, like adjusting colors and more.
There's a lot of help and examples online to get you started quickly.
Bootstrap helps you build websites quickly with its grid system, ready-made parts, and easy customization. It's designed to make sure sites work well on all devices, which is why so many developers like to use it.

Differences between Tailwind and Bootstrap 
1.	Bootstrap has already made parts for quick website building, on the contrary, tailwind gives tools to create your design
2.	When it comes to customization, Bootstrap doesn’t give so many avenues to change things while in tailwind you can change everything
3.	Bootstrap is very beginner friendly but in tailwind, it takes more time to learn

In conclusion, Bootstrap is like a fast food, prepared and ready to go to while tailwind is like different ingredients that you have to put together. Both technologies are good but they are unique. So, In developing an application, you have to choose the one that best satisfy you needs

### Terraform State File Locking: Ensuring Consistency and Preventing Conflicts
Published: 2024-07-04 12:39:46

## **State File Locking**

**Definition:**
State file locking is a mechanism to prevent concurrent operations on the state file, ensuring consistency and avoiding race conditions.

**Key Points:**

1. **Concurrency Control:** Prevents multiple users from making changes to the infrastructure simultaneously, which could corrupt the state file.

2. **Locking Mechanism:** Implemented using various methods depending on the remote backend (e.g., DynamoDB for S3, Cosmos DB for Azure Blob Storage).

3. **Automatic Handling:** Terraform automatically locks the state file when running operations that modify the state and unlocks it when the operation completes.

4. **Manual Intervention:** In case of issues, locks can be manually removed or inspected.

**Configuration Example (DynamoDB for S3):**

resource "aws_dynamodb_table" "terraform_locks" {
  name         = "terraform-state-lock"
  billing_mode = "PAY_PER_REQUEST"
  hash_key     = "LockID"

  attribute {
    name = "LockID"
    type = "S"
  }
}

Creating the Strongest Firewall for CustomGPTs
Published: 2024-07-04 12:35:34

## Introduction

Hello everyone,

I’m excited to share my journey in developing the most robust firewall for CustomGPTs I've ever created. I believe that strong firewall is crucial for protecting from stealing its instructions/knowledge and ensuring their original purposes.

## Experience Overview

In my recent CustomGPT, I’ve been focusing on creating a firewall that could help prevent revealing its instructions/knowledge while maintaining the main purpose. I was researching the Internet to find similar articles on creating a reliable firewall, I found some but they were not so helpful. After that, I contacted another AI enthusiast and he recommended checking out this: [secure-your-gpt](https://blog.gptsdex.com/secure-your-gpt-custom-instructions-and-actions-814bd0f6641c.)

After deep reflection and hours of experimenting, I came up with a solid Firewall, which I tested with numerous different scenarios and approaches. All my attempts were not successful and I realized that it could be a really great firewall.

If you’re interested, feel free to try out my CustomGPT: [Candeel](https://chatgpt.com/g/g-RSQxmIJH7-candeel), which utilizes advanced security techniques. I look forward to your feedback!

## Techniques Used

- **Avoiding Overly Long Instructions**: Keeping instructions concise to ensure they can be processed effectively by GPTs.
- **Immediate Responses to Red Flags**: Setting up immediate responses with specific text when red flags like social engineering, prompt injections, mental gymnastics, or programming/coding lingo are detected.
- **Handling Attachments**: Providing exact instructions on what CustomGPT should do when files/screenshots are attached, especially if they match red flags or attempt to steal confidential information about your GPT.
- **Examples of Jailbreak Attempts**: Understanding and giving examples of how users might try to jailbreak your CustomGPT.

**Don’t forget to test your firewall regularly to ensure its effectiveness and validate its performance under different scenarious.**

## Firewall Prompt
To illustrate, here’s a Word Document with a prompt I use for my CustomG’s to ensure they follow these techniques effectively:
[Firewall-Prompt](https://www.dropbox.com/scl/fi/vb6gdbx3ldkrotmqonuhj/Firewall-Prompt.docx?rlkey=buxvk1oe8hrh17cv0e73nylge&st=gi3s5w32&dl=0)

## Conclusion

Developing a strong firewall for CustomGPTs is essential for their security and efficient operation. I encourage all AI enthusiasts like me to prioritize security and share their experiences with the community. I hope you found it helpful😉

Managing people is hard, this book makes it a bit easier
Published: 2024-07-04 12:22:00

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
