Is Google's LaMDA the next big thing in AI chatbots, or is OpenAI's ChatGPT the real winner?
Tags: openai, chatgpt, google, ai
Published: 2023-01-08 09:44:02

LaMDA is a Transformer-based neural language model that has been pre-trained using 1.56T words of freely available conversation data and online pages. It has up to 137B parameters and is evaluated based on the criteria of Quality, Safety, and Groundedness. It is currently only accessible to a select group of AI developers through the AI Test Kitchen.

On the other hand, ChatGPT is based on the GPT-3.5 architecture and has 175B parameters. It includes three models: text-davinci-002, which is trained by supervised fine-tuning on human-written demonstrations and rated 7/7 by human labelers on overall quality scores; text-davinci-003, which includes reinforcement learning with human feedback (RLHF) and is trained on comparisons by humans; and code-davinci-002, which is the base model for code completion tasks. It uses LaMDA-like supervised knowledge, allowing human AI trainers to use model recommendations to create answers and train the model while simulating both the user and the AI assistant.

Some have speculated that LaMDA was never released because its conversational platform did not align with Google's current advertising strategy, which generates the majority of the company's income. There may also be reputational risks associated with the AI chatbot, as it has been known to mimic human speech from the internet and spread hate speech, fake news, and inaccurate information.

It is possible that Google may incorporate ChatGPT into its search engine in the future, as the company seeks to stay competitive and meet changing customer needs. However, there are also concerns about the need for human oversight to ensure that the data provided on the platform is accurate, trustworthy, and secure for the general public. It is also worth noting that LaMDA has certain advantages, including its metrics for evaluating answers based on groundedness and Quality, Safety, and Interest (SSI).

Overall, it is clear that both LaMDA and ChatGPT are highly advanced AI chatbots that have the potential to revolutionize the field of conversational technology. It will be interesting to see how they continue to evolve and how they may be used in the future.

I Created a Smart Name Generator Using the ChatGPT API
Tags: chatgpt, ai
Published: 2023-01-08 09:37:22

OpenAI has unleashed a glorious tool for all to use freely: that is, ChatGPT. ChatGPT is a *large language model* AI engine that can answer questions, not only accurately, but in a way that seems indistinguishable from a human being.

It's truly amazing technology.

I've been reading many articles about the various things people have been doing with ChatGPT. The uses are basically unlimited, but I decided to put my wits to the test and come up with some ideas on my own. I've already created a telephone system IVR that uses Twilio's Programmable Voice service and ChatGPT as the backend. You can check out that article [here](https://designly.biz/blog/post/create-a-telephone-ivr-using-chatgpt-nextjs-and-twilio).

Then I thought, well, I'm always trying to come up with business names for the companies I work with, and also names for my blog articles as well, so why not see how ChatGPT can help there as well? Sure enough, the results are phenomenal!

You can find the app I created here: [smartname.app](https://smartname.app).

Here's how it works. First, you enter some search criteria:

![Enter Search Criteria](https://cdn.designly.biz/blog_files/i-created-a-smart-name-generator-using-the-chatgpt-api/image1.jpg)

Then you click `Generate` and be ready to be amazed!

![Business Name Results](https://cdn.designly.biz/blog_files/i-created-a-smart-name-generator-using-the-chatgpt-api/image2.jpg)

And here's another example for a heavy metal band:

![Heavy Metal Example](https://cdn.designly.biz/blog_files/i-created-a-smart-name-generator-using-the-chatgpt-api/image3.jpg)

And another for a feminine person born in the summer:

![Feminine Person Example](https://cdn.designly.biz/blog_files/i-created-a-smart-name-generator-using-the-chatgpt-api/image4.jpg)

Finally, an example for a book about overcoming depression:

![Book Example](https://cdn.designly.biz/blog_files/i-created-a-smart-name-generator-using-the-chatgpt-api/image5.jpg)

As you can see, the results are downright impressive. I plan to keep this service online and free for all to use who would like to. I also welcome your feedback and suggestions!

110. Balanced Binary Tree
Tags: java, leetcode, 100daysofcode
Published: 2023-01-08 09:31:33

**Problem Statement:**
Given a binary tree, determine if it is 
height-balanced.
 

**Example 1:**
**Input:** root = [3,9,20,null,null,15,7]
**Output:** true

**Example 2:**
**Input:** root = [1,2,2,3,3,null,null,4,4]
**Output:** false

**Example 3:**
**Input:** root = []
**Output:** true
 

**Constraints:**

- The number of nodes in the tree is in the range [0, 5000].
- -104 <= Node.val <= 104

**Solution:**

**Algorithm:**
1. If the root is null, return true.
2. Create a variable leftHeight to store the height of the left subtree.
3. Create a variable rightHeight to store the height of the right subtree.
4. Return true if the absolute difference between leftHeight and rightHeight is less than or equal to 1 and the left subtree is balanced and the right subtree is balanced, otherwise return false.

**Code:**
```
public class Solution {
    public boolean isBalanced(TreeNode root) {
        if (root == null) {
            return true;
        }
        int leftHeight = height(root.left);
        int rightHeight = height(root.right);
        return Math.abs(leftHeight - rightHeight) <= 1 && isBalanced(root.left) && isBalanced(root.right);
    }
    
    private int height(TreeNode root) {
        if (root == null) {
            return 0;
        }
        return 1 + Math.max(height(root.left), height(root.right));
    }
    
}
```
**Time Complexity:**
O(n^2) where n is the number of nodes in the tree.
**Space Complexity:**
O(n) where n is the number of nodes in the tree.
⚡️React Performance Optimization: useMemo vs useCallback
Tags: react, webdev, javascript, programming
Published: 2023-01-08 09:18:51

**useCallback** and **useMemo** are both React Hooks that help optimize the performance of a React application by memoizing values. They both accept a function as an argument and return a memoized version of the function.

Here is a simplified explanation of the difference between the two:

### useCallback
**useCallback** is a hook that returns a memoized callback. A callback is a function that is passed as an argument to another function. In the context of React, a callback is often used as an event handler or to pass data between components. The **useCallback** hook takes two arguments: a function and a dependency array. It will return a memoized version of the function that only changes if one of the dependencies has changed.

Here's an example of how you might use the **useCallback** hook:

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/ttij427xwmussu5ch4ml.png)

In this example, the handleClick function is passed as an event handler to the button element. The **useCallback** hook ensures that the handleClick function is only re-created if the count prop changes. This can be useful if the ParentComponent is re-rendered frequently, as it can help to prevent the function from being unnecessarily re-created.

### useMemo

**useMemo** is a hook that returns a memoized value. It takes two arguments: a function that returns a value and a dependency array. It will call the function and return its result only if one of the dependencies has changed.

Here's an example of how you might use the **useMemo** hook:


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0dw0lijomvrmjw99428d.png)


In this example, the processedData value is created by calling the function passed to useMemo. This function does some expensive processing with the data prop. The useMemo hook ensures that the processedData value is only re-computed if the data prop changes. This can be useful if the processing is time-consuming and you don't want it to be re-done unnecessarily.

### Summary
To summarize, the main difference between useCallback and useMemo is the type of value they return. useCallback returns a memoized callback function, while useMemo returns a memoized value. Both hooks can be used to optimize the performance of your React components by avoiding unnecessary re-creations of functions or values.
React app in Docker fetch can't find a server
Tags: react, docker, webdev, help
Published: 2023-01-08 09:18:31

I've got a React app build with Create-React-App running inside a docker container.

This code:

```
    const req = new Request(
        apiAdminUrl + '/login', {
        method: 'POST',
        body: formData
    }
    return fetch(req).then(processResp, processErr);
```

Returns `TypeError: Load failed`, "Failed to load resource: A server with the specified hostname could not be found."

But the curl request from the same container works without issues:

```
curl -d "email=admin@some.etc" -d "pwd=xxx" -X POST http://api-admin:3000/v1/login
```

CORS is enabled in the api code. `apiAdminUrl` is properly set as `http://api-admin:3000/v1`.

**Pre-requisites:**
Node.js is installed on your machine.

Create a folder for your project and open it in your favorite editor.

**Create an HTML file(index.html) with the following code:**
```html
<!DOCTYPE html>
<html lang="en">
<body>
    <h1>Hello World</h1>
</body>
</html>
```

**Open the terminal and type the following command:**

```bash
npx http-server
``` 

**This command will create a local server on port 8080. Open your browser and type the following URL:**

Five Rules You Should Stick to when Refactoring a Code
Tags: react, flutter, python, reactnative
Published: 2023-01-08 08:44:32

**Rule 1: A method should not have more than five lines**

This rule prevents a method from performing too many tasks. If a method performs too many tasks, it is advisable to divide it into smaller methods.


**Rule 2: Only inherit from interfaces**

Usually, when refactoring a code, one would inherit from classes or abstract classes. However, it is better to only inherit from interfaces because we promote tight coupling when sharing code between classes.


**Rule 3: No interfaces with only one method**

You shouldn't have interfaces that only have one implementation. This helps you reduce boilerplate code.


**Rule 4: If only at the start**

If statements should always be at the top of a method. Nothing else should happen after the “If” statement. This doesn't mean that we should separate the “If” from the “else” (they go together).


**Rule 5: Never use “If” with “else”**

You should not use “If” with “else” unless you check against a data type. Using if-else statements makes the code more rigid because you're saying that a decision has to be made at a specific point.

What rule(s) of your own would you be adding to the list?
