## ✨ **Resumen del Proceso:**


Comienza con una cuenta en OpenAI y **obtén tus claves API**. Configura tu proyecto Next.js y prepárate para instalar las dependencias cruciales: `ai` y `openai`. **Integra el chat** en tu aplicación utilizando el hook `useChat`, y crea una ruta API que manejará las peticiones POST para **interactuar con OpenAI**.


## 🧩 **Código Clave: Desvelando la Magia del Desarrollo:**


Para la API, tu archivo `app/api/chat/route-.ts` se verá así:

```typescript
import { OpenAIStream, StreamingTextResponse } from "ai";
import OpenAI from "openai";

export const runtime = "edge";

const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY! });

export async function POST(req: Request) {
  const { messages } = await req.json();

  const res = await openai.chat.completions.create({
    model: "gpt-4-turbo-preview",
    stream: true,
    messages,
  });

  const stream = OpenAIStream(res);

  return new StreamingTextResponse(stream);
}
```

Y tu componente principal en `app/page.tsx` incorporará el chat de esta manera:

```tsx
"use client";
import { useChat } from "ai/react";

export default function Home() {
  const { messages, input, handleInputChange, handleSubmit } = useChat();

  return (
    <main className="flex min-h-screen flex-col items-center justify-between p-24">
      <h1 className="text-3xl">Fast AI app</h1>

      <form onSubmit={handleSubmit} className="flex flex-col gap-2">
        <label className="flex flex-col gap-2">
          <input
            placeholder="What are your thoughts?"
            value={input}
            onChange={handleInputChange}
            className="bg-black outline text-white p-2 rounded-sm"
          />
        </label>
        <button type="submit" className="bg-white text-black rounded-xl">
          **Ask AI**
        </button>
      </form>
      <ul>
        {messages.map((m, index) => (
          <li key={index} className="p-2 bg-white/05 rounded-xl">
            {m.role === "user" ? "**User:** " : "**AI:** "}
            {m.content}
          </li>
        ))}
      </ul>
    </main>
  );
}
```

How to Improve the Battery Life of Any Cell Phone?
Published: 2024-03-09 08:37:42


Improving the battery life of your cell phone involves adopting good habits, optimizing settings, and managing apps efficiently. Here are some tips to help enhance the battery life of any cell phone:

Adjust Screen Brightness:

Reduce screen brightness or enable adaptive brightness to adjust automatically based on ambient light. A lower brightness level can significantly conserve battery power.
Screen Timeout:

Set a shorter screen [tech play games app](https://techplaygames.co/)  timeout period. The shorter the time your screen stays on when not in use, the less power it consumes.
Manage Background Apps:

Close apps running in the background that you're not actively using. Background processes can drain battery life, so regularly check and close unnecessary apps.
Update Apps and Operating System:

Keep your apps and the operating system up to date. Developers often release updates that include optimizations and improvements, which can positively impact battery performance.
Turn Off Location Services:

Use location services only when needed. GPS and location-based apps can consume a significant amount of power. Turn off location services for apps that don't require them.
Manage Push Notifications:

Limit the use of push notifications or reduce the frequency. Push notifications can wake up your phone and drain the battery.
Use Wi-Fi Whenever Possible:

Connect to Wi-Fi networks when available, especially for data-heavy activities like streaming videos or downloading large files. Wi-Fi generally consumes less power than mobile data.
Enable Power-Saving Mode:

Many smartphones come with built-in power-saving modes. Activate these modes to limit background processes, reduce screen brightness, and optimize other settings when your battery is running low.
Optimize Sync Settings:

Adjust the sync settings for email and other apps. Increase the interval between syncs or set them to manual to reduce the frequency of updates.
Disable Unnecessary Features:

Turn off features like Bluetooth, NFC, and animated wallpapers when not in use. These features can contribute to battery drain.
Manage Widgets:

Remove unnecessary widgets from your home screen. Widgets that constantly update can consume battery power.
Limit Background Data Usage:

Restrict background data usage for apps that don't require constant data updates. This can be particularly useful for apps running in the background.
By adopting these practices and staying mindful of your phone usage, you can optimize your cell phone's battery life and ensure it lasts longer between charges. Keep in mind that some settings and options may vary depending on your specific device and operating system.

Published: 2024-03-09 08:35:35

In the ever-evolving landscape of cloud computing, the AWS Well-Architected Framework stands as a beacon of best practices and strategic guidance. It empowers architects and developers to build secure, high-performing, resilient, and efficient infrastructure for their applications. But what exactly are the pillars that uphold this framework, and how do they translate into real-world success? Let’s explore & walk through with brief example for better understanding.

<b>The Six Pillars of Excellence</b>: -
The AWS Well-Architected Framework is built upon six foundational pillars, each addressing a key aspect of architecture in the cloud:

<b><u>Operational Excellence</b></u>: - This pillar focuses on the ability to run and monitor systems to deliver business value and to continually improve processes and procedures.
- <b><u>Use case</b></u>: - A company uses infrastructure as code (IaC) to automate the deployment of their application, ensuring consistent and repeatable processes.

<b><u>Security</b></u>: - Prioritizing the protection of information and systems is crucial, with a focus on confidentiality, integrity, and availability of data. 
- <b><u>Use case</b></u>: - An online retailer ecommerce business implements multi-factor authentication (MFA) and encryption for data at rest and in transit to protect customer information.

<b><u>Reliability</b></u>: Ensuring a workload performs its intended function correctly and consistently over time by handling changes in demand and recovering from failures.
- <b><u>Use case</b></u>: - A streaming service uses AWS Auto Scaling and Amazon Route 53 to handle high traffic loads during peak hours, ensuring uptime and performance.

<b><u>Performance Efficiency</b></u>: Using computing resources efficiently to meet system requirements and maintaining efficiency as demand changes and technologies evolve.
- <b><u>Use case</b></u>:-A mobile gaming company uses Amazon Elastic Compute Cloud (EC2) Spot Instances to process gaming data, optimizing resource usage and reducing costs.

<b><u>Cost Optimization</b></u>: Avoiding unnecessary costs by understanding and controlling where money is being spent, selecting the most appropriate and right number of resource types, analyzing spend over time, and scaling to meet business needs without overspending.
- <b><u>Use case</b></u>: - A media company utilizes AWS Cost Explorer, AWS Budgets to track and analyze their spending patterns, allowing them to adjust resource usage and save on costs.

<b><u>Sustainability</b></u>: Reducing the environmental impact of running cloud workloads by improving efficiency and using less resources.
- <b><u>Use case</b></u>: - A software firm selects AWS regions based on the proximity to their user base, reducing latency and the carbon footprint associated with data transmission.

Ethereum contracts system is inferior
Tags: solidity, blockchain, ton, architecture
Published: 2024-03-09 08:12:09

Let's suppose we are new to Ethereum (for instance, it is true for me) and want to write a smart contract! What should we do?

The logical thing is to start with [architecture overview](https://ethereum.org/en/developers/docs/accounts/)!

- We see there are externally-owned and contract accounts; *externally-owned can transfer ETH and tokens...* wait... are tokens a thing defined by the blockchain structure? If tokens need a rework, blockchain will need to be changed?
- Then, *all accounts have nonce values*; it has **different** meaning based on whether account is a smart contract (*number of transactions sent* versus *number of contracts created*). Also, the blockchain core somewhy takes responsibility of deduplicating transactions.
- *EVM code gets executed if the account gets a message call* - are there other kinds of messages?
- *storageRoot – Sometimes known as a storage hash. A 256-bit hash of the root node of a Merkle Patricia trie that encodes the storage contents of the account (a mapping between 256-bit integer values)* - contract storage is flat? What if one needed to store two mappings from user address to their data in a contract?
- When going further, we notice variety of modifiers on functions (payable, view, pure, external...)

---

I believe system of TON Blockchain ([The Open Network](https://ton.org)) here is much straighter:

- TON operates on accounts as well. They are all smart contracts (contain code, balance and data).
- Externally-owned Ethereum accounts translate to *wallet* contracts - special programs that keep user's public key in data and, upon reception of *external messages*, validate signature and perform the corresponding actions.
    * Wallet contracts can be different and even created by developers, without any need for approval from someone else.
    * Users can change signature validation method, using secp256k1 or any method they like instead of Ed25519. They may abandon asymmetric cryptography altogether!
    * Wallets can include additional functionality, like restricting destination addresses to a specific set (so you can provide someone funds for staking without ability to spend them all on NFTs) or etc.
- Messages are blobs of data, either imported into blockchain from the outer world (they are called *external*) or carrying value from one contract to another *internally*.
- Transaction is an update on contract state when it processes incoming message. Contracts are isolated: to interact with others, they send outgoing messages.
    * From validators' point of view, each transaction can be computed efficiently due to being related to one account only.
    * From developers' point of view, interacting with malicious contract cannot interrupt normal operation of your (compare with reentrancy concerns in Ethereum) or cause gas exhaustion.
    * From users' point of view, a malicious contract cannot do anything to their assets even if user is sending messages to it! TON, tokens (jettons) and NFTs are all kept secure.

Focus On What Matters
Published: 2024-03-09 08:01:07

Today I read the First Chapter of this amazing book
‘Focus on What Matters’

These are my learnings from the first chapter:

```
pip install
```

1. Identify Controllable Elements:
   - Take time to distinguish between things you can control and those you cannot.
   - Make a list of aspects of your life that are within your control, such as your attitude, actions, and responses.

2. Let Go of the Uncontrollable:
   - Release unnecessary stress by accepting that some things are beyond your control.
   - Practice letting go of worries about external factors that you cannot influence.

3. Mindful Awareness:
   - Develop mindfulness to stay present and discern the factors you can influence in any given situation.
   - Train your mind to focus on the current moment rather than dwelling on uncontrollable future outcomes.

4. Set Realistic Goals:
   - Establish achievable goals based on the aspects of your life you can control.
   - Break down larger goals into smaller, manageable steps to maintain a sense of control.

5. Prioritize Energy and Time:
   - Allocate your time and energy to the areas of life where you have the most influence.
   - Avoid investing excessive resources into situations or relationships beyond your control.

6. Adaptability:
   - Embrace change and cultivate an adaptive mindset.
   - Focus on adjusting your own actions and responses rather than trying to control external events.

7. Learn from Mistakes:
   - Recognize mistakes as opportunities for growth within your control.
   - Develop a habit of self-reflection to extract valuable lessons from your experiences.

8. Communication Skills:
   - Concentrate on enhancing your communication skills, as this is a controllable aspect that influences relationships and outcomes.
   - Choose words and expressions thoughtfully to positively impact your interactions.

9. Personal Accountability:
   - Take responsibility for your actions and decisions.
   - Avoid blaming external factors for challenges; instead, focus on what you can do differently moving forward.

10. Emotional Resilience:
    - Strengthen your emotional resilience by focusing on your reactions to situations.
    - Practice maintaining a calm and composed demeanor in the face of adversity.

Remember, the key is to consistently apply these principles in your daily life to develop a mindset that focuses on what you can control, ultimately leading to a more fulfilling and purposeful existence.
Telegram bot for dating based on cinematic preferences
Tags: telegram, bot, dating, movies
Published: 2024-03-09 07:47:00


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fuxautw9a047em4e9hzb.png)

Most dating apps only allow you to see a photo and profile of a potential partner before making a dating decision. Everything else can be found out only by chatting with him, talking on the phone or on a real date. But you need to spend time on each such additional testing. In most cases, this time will be wasted simply because far from all people are compatible in character and psyche.

It would be great to have an extra option to filter the list of potential dating candidates so that you don’t waste so much time. And I offer you this possibility: if you know what kind of movies a stranger likes, then this gives you important additional information about its character, culture, sense of humor, and other tastes. Now it will be easier for you to make a decision: whether to start dating?

Moreover, the “Dating by Favorite Movies” application from the [MegaPort bot](https://megaport.biz) will match you with potential contacts with lists of favorite movies matching yours. In the future, it will be easier for you to start a conversation on the first date, for example, by discussing the best moments from your favorite movies.

In general, the coincidence of cinematic preferences plays an important role in building relationships. Couples who watch TV shows and films together will experience a deeper connection through their shared immersion in fictional worlds, [the study](https://journals.sagepub.com/doi/full/10.1177/0265407516660388) published in the "Journal of Social and Personal Relationships" reveals. I haven’t personally met stable couples in which the partners have different movie tastes and watch movies separately.

An important feature of this application is the possibility to create a user profile page in addition to the list of favorite movies. On this page, users can post additional information about themselves in any form: texts, photos, videos. This page will appear in the search results for every potential contact that the bot finds for you. And of course, the usual tools for dating services are available: filtering by gender, age and geolocation.

After you decide on the criteria, the bot selects potential contacts for you that meet the criteria you set. Then for each contact you make a decision whether it suits you or not. If the contact suits you, you approve of him, if contact approves of you in return, then the bot will give you the opportunity to write or talk to each other in a regular Telegram chat for users, and then you can communicate without the bot.

This is a brief description, but it’s actually a bit more complicated, but you can find all the details in [the guide](https://megaport.biz/fmd_en.html) for this app.
