¿Que son los Kudos?
Tags: kudos, tech, teams, partners
Published: 2023-03-05 12:56:35

Si me hubieran preguntado el año pasado qué son los kudos no habría sabido responder porque es un término con el que soy familiar hace solo unos meses, pues resulta que la primera vez que lo escuché no entendí a qué se refería ni en qué contexto se podría utilizar. Era una de mis primeras reuniones en un equipo y por lo mismo no tenía la suficiente confianza para levantar la mano y preguntar en público por ese miedo que todos hemos tenido alguna vez de hacer la mal llamada **_“pregunta boba”_**; quedé con la duda y una vez terminó el daily le escribí por interno a un compañero para que por favor me diera un contexto de cómo y en qué momento utilizarlo, pues también los kudos tienen un timing en los equipos de trabajo, generalmente se dan en las reuniones de retrospectiva, si estás en un entorno de trabajo ágil como **SCRUM.**

Dar kudos es básicamente la acción de reconocer el mérito a alguien por el buen trabajo, desempeño, rendimiento, performance, como le quieras decir, que alguien a tu alrededor ha venido realizando. No es más que eso, es una acción simple con la que puedes darle valor a quien lo merece, hacerlo no te quita valor a ti, pues estas dejando saber que notas el esfuerzo que se está haciendo para mejorar y lograr avances en los objetivos que cada persona tiene y que además, en esa misma dirección permite el progreso y crecimiento del equipo de trabajo que todos hacen parte, si ese es el caso.

Pocas personas entienden el valor que le da a uno mismo reconocer, pero más que eso manifestar de manera explícita y en público el buen trabajo que hacen los demás, hacerlo te hace ser una persona o profesional vulnerable en el sentido de que tu mente subconsciente lo interioriza y al mismo tiempo te motiva a querer ser parte de eso, vas a querer mejorar y seguir la misma ruta que tus compañeros de equipo. 

***Conclusión,*** no seas tímido, se puede dar valor a los demás reconociendo sus méritos. 

En el momento que consideres que alguien está haciendo algo bien simplemente se lo dejas saber. Así esa persona te lo va a agradecer y sabrá que va por buen camino en cualquier cosa que esté trabajando, emprendiendo o simplemente estudiando…

### Building a RESTful API with Node.js, Express.js, and MongoDB — Part 1

![](https://cdn-images-1.medium.com/max/1024/1*Gd5C9QvX8xIcRTscnVN_7w.jpeg)

Part 1: Introduction and Setup

In today’s digital age, APIs are an integral part of web and mobile development. With Node.js and Express.js, creating a powerful and scalable API has never been easier. In this tutorial, we will walk you through the process of creating an API using Node.js and Express.js with Mongoose as the database ORM.

Before we dive into the code, let’s take a moment to understand what Node.js, Express.js, and Mongoose are and why they are so popular.

Node.js is a powerful, open-source, cross-platform JavaScript runtime environment that allows developers to run JavaScript outside of a web browser. It is built on top of the V8 JavaScript engine and provides a non-blocking, event-driven I/O model that is perfect for building scalable, data-intensive applications.

Express.js is a minimalist and flexible web framework for Node.js that provides a set of robust features for building web and mobile applications. It is built on top of Node.js and provides a simple, yet powerful, API for building HTTP servers, handling requests and responses, and routing.

Mongoose is a powerful Object-Document Mapping (ODM) library for MongoDB and Node.js. It provides a simple, yet powerful, API for interacting with MongoDB databases and makes it easy to define schemas, validate data, and perform CRUD operations.

Now that we have a basic understanding of what Node.js, Express.js, and Mongoose are, let’s set up our project.

To get started, you will need to have Node.js and npm (Node Package Manager) installed on your machine. You can download and install them from the official Node.js website.

Once you have Node.js and npm installed, open up your terminal and create a new directory for your project. Navigate to the directory and run the following command to initialize a new Node.js project:

```
npm init -y
```

This command will create a new `package.json` file in your project directory. The `package.json` file is used to manage the dependencies and scripts for your project.

Next, we need to install Express.js and Mongoose. Run the following commands in your terminal:

```
npm install express
npm install mongooseba
```

These commands will install Express.js and Mongoose as dependencies for your project.

Now that we have our project set up, let’s move on to creating our API. In the next part of this tutorial, we will create a basic server using Express.js and connect it to a MongoDB database using Mongoose.
Programming Arduino with Python
Tags: programming, arduino, python, computerscience
Published: 2023-03-05 12:26:07

Arduino is an open-source hardware and software platform that is popularly used for building electronic projects. While the Arduino IDE (Integrated Development Environment) is the go-to tool for programming an Arduino board, Python can also be used as an alternative. In this documentation, we will explore how to program an Arduino board using Python.

Prerequisites:

- An Arduino board
- Arduino IDE installed on your computer
- PySerial library installed on your computer

*Step 1: Install PySerial Library*
PySerial is a Python library that enables communication between a Python script and a serial port, which is the interface used to communicate with an Arduino board. To install PySerial, open your terminal or command prompt and type the following command:

```
pip install pyserial

```

*Step 2: Connect the Arduino Board*
Connect the Arduino board to your computer using a USB cable. Make sure that the board is properly powered and the LED light is on.

*Step 3: Upload Arduino Sketch*
Before we can start communicating with the Arduino board using Python, we need to upload a sketch to the board that will listen for incoming serial data. Open the Arduino IDE and create a new sketch. Copy and paste the following code into the sketch:

```
void setup() {
  Serial.begin(9600);
}

void loop() {
  if (Serial.available() > 0) {
    char data = Serial.read();
    Serial.write(data);
  }
}
```

This code listens for incoming data on the serial port and echoes it back to the computer. Compile and upload the sketch to the Arduino board.

*Step 4: Write Python Code*
Now that the Arduino board is set up to receive serial data, we can write a Python script to send data to the board. Open your text editor and create a new Python script. Import the PySerial library and create a serial object that corresponds to the serial port that the Arduino board is connected to:

```
import serial

ser = serial.Serial('COM3', 9600)

```

Replace `'COM3'` with the name of the serial port that your Arduino board is connected to.

Next, we can send data to the board using the serial object:

```
ser.write(b'Hello, Arduino!')

```

This code sends the string "Hello, Arduino!" to the Arduino board.

*Step 5: Run Python Script*
Save the Python script and run it in the terminal or command prompt. You should see the message "Hello, Arduino!" echoed back to the terminal.

Congratulations! You have successfully programmed an Arduino board using Python.

Note: This is just a basic example to get you started. You can explore more advanced features of PySerial to send and receive data to and from the Arduino board.
From Dream to Danger: Building an AI Learning Companion App and the Potential Letdown.

<hr/>
> Remember that one friend you had in school who was always great at science or math, while another was a master in history or football? It was as if they had their own little superpowers. The thing is, they also had other stuff/subjects they were great or at least good at. What if you could create a learning companion who had the combination of skills and knowledge you needed, tailored to your specific interests? 

That's the idea behind SmartStudy Companions, a web app I'm building that will give you your own personal AI study buddies. 

*" With this app, you'll never have to study alone again. Your exposure to new ideas will be on a self-paced rise as your customized companions will be there to share unique insights, keep you company, and help you learn in ways you never experienced or thought possible. Whether you need help with art, music, study habits, languages, learning, ancient history, cooking or even soccer, your companions have got you covered. "*

But let me be honest with you - this project is far from risk-free. While I believe that SmartStudy Companions has the potential to revolutionize the way we learn and study, there's always the danger that it might not live up to expectations. After all, what happens when you combine seemingly disparate fields - like soccer and culinary arts - into a single companion? Will it be a game-changer, or a complete dud?

Despite these uncertainties, I'm excited to share my journey with you as I build SmartStudy Companions. As a progressive web app, I'm using Nuxt.js, Express, and MongoDB to create a lightweight, fast, and responsive experience for users. And while I'm still deciding on whether to make it open source or not, I'm excited about the possibility of collaborating with other developers to create something truly unique and groundbreaking. <small> Exploring some form of balance between open and closed-source is also a looming thought but i digress.<small/>

In this series, I'll be documenting my process, from ideation to MVP, to public beta, and beyond. You'll get an inside look at my thought process, the challenges I face, the successes and setbacks, and the lessons I'm learning along the way. Whether you're a developer, a student, or simply curious about AI and education, I hope this series will be both informative and entertaining.

So join me on this journey, as we ride the wave of uncertainty and discover whether SmartStudy Companions will be the future of learning, or a potential letdown.
Why to useMemo hook?
Tags: react, javascript, tutorial, webdev
Published: 2023-03-05 12:09:16

Suppose you have a module that displays a listing of products, each one with its own label and cost. Moreover, you have a separate function that determines the collective price for all the items. This is an illustration of how to employ the useMemo hook to store the result of the total price calculation:

```

import React, { useMemo } from 'react';

function ItemList({ items }) {
  const totalPrice = useMemo(() => {
    console.log('Calculating total price...');
    return items.reduce((acc, item) => acc + item.price, 0);
  }, [items]);

  return (
    <div>
      <ul>
        {items.map((item) => (
          <li key={item.name}>
            {item.name}: {item.price}
          </li>
        ))}
      </ul>
      <p>Total price: {totalPrice}</p>
    </div>
  );
}

```
The useMemo hook lets us set up a variable, entitled totalPrice, in this instance. The first piece of the hook is a function that works out the cost of all the items; the second part is an array of dependencies, meaning that React will recalculate the price any time the dependencies alter. In this instance, the only thing that the calculation is reliant on is the items prop.

The useMemo hook memorizes the result of the function, so if the items prop hasn't changed since the last render, React will take the previous result instead of running the function again. This can be helpful for complicated calculations that don't need to be re-run every time the render is executed. For example, if there is a large list of items, figuring out the total cost on every render could be time-consuming; memorizing the result can increase performance.

It is worth noting that useMemo is not a substitute for useEffect. useMemo should be used to store the outcome of a function, while useEffect should be used for completing side effects like obtaining data from an API.
Building a Complete ReactJS App with Hooks and a Document Database: Essential Technologies to Learn
Tags: react, mongodb, webdev, programming
Published: 2023-03-05 12:07:22

To build a complete ReactJS app with hooks and a document database, you will need to learn a combination of frontend and backend technologies. Here are some of the technologies you should learn from start to end:

## Frontend Technologies:
**ReactJS:** This is the core technology for building the frontend of your app. You should learn how to use `ReactJS` to create components, manage state, and handle user interactions.

**React Hooks:** React Hooks are used to managing state and other React features. You should learn how to use hooks like `useState`, `useEffect`, and `useContext` to build your app.

**React Router:** This is a library that allows you to handle routing in your React app. You should learn how to use React Router to create routes and navigate between pages.

**Axios:** Axios is a library that allows you to make `HTTP` requests from your React app. You should learn how to use Axios to communicate with your backend API.

## Backend Technologies:
**Node.js:** This is a JavaScript runtime environment that is used to run your backend server. You should learn how to use `Node.js` to create a backend server that can handle `API` requests.

**Express.js:** This is a framework that is built on top of Node.js and is used to create `REST APIs`. You should learn how to use Express.js to create routes and handle API requests.

**MongoDB:** This is a document database that is commonly used in `Node.js` applications. You should learn how to use `MongoDB` to store and retrieve data for your app.

**Mongoose:** This is an Object-Document Mapping (ODM) library that allows you to interact with `MongoDB` in a more intuitive way. You should learn how to use Mongoose to create models and perform `CRUD` operations on your database.

## Other Technologies:
**JSON Web Tokens (JWT):** JWT is a technology that is commonly used for authentication in web applications. You should learn how to use `JWT` to authenticate users in your app.

**Git:** Git is a version control system that is used to manage your app's source code. You should learn how to use Git to track changes and collaborate with other developers.

Overall, building a complete ReactJS app with hooks and a document database requires a combination of frontend and backend technologies. You should learn how to use ReactJS, React Hooks, React Router, and Axios for the frontend, and Node.js, Express.js, MongoDB, and Mongoose for the backend. Additionally, you should learn other technologies like JWT and Git to help you build and manage your app.

By mastering these technologies, you can build powerful and scalable applications that are well-structured and easy to maintain. Happy learning!
Golang Distributed Tracing with OpenTelemetry - Solving the Challenge
Tags: go, distributedsystems, devops, microservices
Published: 2023-03-05 12:07:09

This is a preview - LInk to the full article is provided below

OpenTelemetry (OTel ) an open-source framework for trace based observability, provides a standard set of vendor-agonistic SDKs, APIs, and variety of tools to connect with observability backends. It supports all major programming languages, including Java, Python, Node.js, dotnet and Go.

However, Golang distributed tracing (for observability, debugging and testing), through integrating OTel with Go is challenging due to several reasons. 

This article demonstrates the biggest challenges and it offers a new approach instead, for compile-time auto-instrumentation makes the process of tracing Golang faster and with much less friction.

Read on how Golang tracing is executed today, and view an example of the exact steps to simplify it

Build a Modern API with Slim 4 - Add your First Route
Tags: api, tutorial, php
Published: 2023-03-05 12:00:00

Now that we have our application up and running, we need to make it actually look our for calls on certain routes, as it stands it won't actually do that as we haven't told it what to look out for.

As mentioned way back in the introduction, we will be creating a bookstore API, so let's first of all create a `/books` endpoint. This all goes in our `src/routes` folder:

```php
src/routes/books.php

<?php

$app->group('/books', function($app) {
  $app->get('', function($request, $response, $args) {
    // Code will go here
  });
}
```

And in our `index` file we add, between creating the `app` and adding the 3 middlewares:

```php
...
AppFactory::setContainer($container);
$app = AppFactory::create();

require __DIR__ . '/../src/routes/books.php';

$app->addBodyParsingMiddleware();
...
```

Wait, so, what have we actually done here? Well firstly we've included our `books` file in our index, as without that it will never even attempt to run it, then in our `books` file we've added a group called books, inside which we've added a GET endpoint with an empty endpoint, this has enabled the `api.bookstore.com/books` endpoint. Had we done, say, `$app->get('all' ...` then it would be `api.bookstore.com/books/all`.

However, this isn't what our final `books` file will look like. Ideally we want this file to just handle the routing and add any associated middlewares (JSON validation for example which won't be on every route). We need to make use of our `controllers` directory for this.
Introduction to Computer Hardware
Tags: computerscience, beginners, algorithms, tutorial
Published: 2023-03-05 11:18:17

Computer hardware is the collection of physical parts that make up a computer system. It includes components such as the motherboard, processor, memory, storage devices, input/output devices, and other peripheral devices. In this documentation, we will explore each component in detail.

*Motherboard*

The motherboard is the main printed circuit board (PCB) that houses the various components of a computer system. It connects all the other components together and provides communication channels for them to interact with each other. It also includes expansion slots for adding additional components to the system.

*Processor*

The processor, also known as the Central Processing Unit (CPU), is the brain of the computer system. It is responsible for executing the instructions that the computer receives. The performance of a computer system is largely dependent on the speed and efficiency of its processor.

*Memory*

Memory, also known as Random Access Memory (RAM), is a temporary storage area that stores the data and instructions currently being used by the processor. The more memory a computer has, the faster it can access and process data.

*Storage Devices*

Storage devices are used to store data and programs permanently. They include Hard Disk Drives (HDDs), Solid State Drives (SSDs), and Optical Drives. HDDs are the traditional storage devices that use spinning disks to store data, while SSDs are newer and faster storage devices that use flash memory to store data.

*Input/Output Devices*

Input devices are used to provide input to a computer system, while output devices are used to display the output generated by the computer system. Examples of input devices include keyboards, mice, and scanners, while examples of output devices include monitors, printers, and speakers.

*Peripheral Devices*

Peripheral devices are devices that are not essential to the functioning of a computer system but are used to enhance its functionality. Examples of peripheral devices include webcams, microphones, and external hard drives.

*Conclusion*

Understanding computer hardware is essential for anyone looking to build or repair a computer system. It is also important for anyone looking to purchase a new computer system, as having a basic understanding of the different components can help in making informed purchasing decisions.
