RxJS Operators: map
Tags: rxjs, webdev, typescript, javascript
Published: 2023-06-14 05:30:00

RxJS is a JavaScript library that enables the creation of asynchronous and event-based programs. The main type is the `Observable` and a suite of functions and operators are provided to make it easier to work with the data coming through. This series will detail those operators (and a few stand-alone functions) and provide examples of their use.

In this post, we’re going to cover the `map` operator.

## What does it do?

The `map` operator works the same way as the Array function by the same name. We pass in a function that accepts the current values, performs an operation, and returns the new result. Any operators that come after the `map` operator will then be using the new value returned from the function.

## Example

```tsx
import { interval, map } from 'rxjs';

interval(1000)
    .pipe(map(x => `Value mapped: ${x}`))
    .subscribe(x => {
        console.log(x);
    });
```

Here `interval` is providing sequential integers. The function we pass to the `map` operator creates a string including that value and returns it. If we run this we will see:

```bash
Value mapped: 0
Value mapped: 1
Value mapped: 2
Value mapped: 3
Value mapped: 4
Value mapped: 5
```

This is a simple example that shows the basic usage of the `map` operator. More complicated implementations may be used to select specific values of objects that are passed. Or we could apply calculations and return that. The point is, there’s not really a limit to what we can do within the `map` operator.

There is one caveat. Don’t try and utilise other observables as part of your function. If we want to make use of other observables there are specialised methods to handle this:

- `concatMap`
- `exhaustMap`
- `mergeMap`
- `switchMap`

These will be covered in future posts. For now, just stick to basic operations when using `map`.

The source code for this example is available on GitHub:

Introduction to DAPPER in .NET Apps Unlocking the Power of Simplified Database Access
Tags: codenewbie, programming, dotnet, coding
Published: 2023-06-14 04:53:28

Dapper - A Simple Object Mapper for .NET.

Tired of wrestling with complex ORMs and bloated data access frameworks? Dapper.NET, the lightweight and efficient micro-ORM that will revolutionize how you interact with databases in your .NET applications.



🚀 What is Dapper.NET? 🚀

Dapper.NET is a simple object mapper for .NET and .NET Core applications. Created by the folks at Stack Exchange, it's designed to be fast, flexible, and straightforward to use. It just a wrapper around ADO.NET. 



💪 Why Choose Dapper.NET? 💪

Dapper.NET, you'll experience significantly reduced overhead compared to heavyweight ORMs, resulting in lightning-fast data access.



Simplicity at its Core: Dapper.NET focuses on simplicity and ease of use. It doesn't attempt to abstract away the database, allowing you to write and optimize your SQL queries directly.



Flexibility and Compatibility: Dapper.NET works seamlessly with a wide range of databases, including SQL Server, MySQL, PostgreSQL, SQLite, Oracle, and more.



🔉 Cons Of Using Dapper 🔉

Manual Query Construction: Unlike full-fledged ORMs, Dapper.NET requires you to write raw SQL queries manually. Unless you need a little feel like EF Core you can use Dapper Fast Crud Nuget Package. 

👇 

https://github.com/MoonStorm/FastCrud



Dapper.NET focuses on providing a lightweight and efficient mapping between query results and objects. However, it lacks higher-level abstractions, such as entity tracking, change tracking, or automatic relationship handling. 



Since Dapper.NET doesn't abstract away the database or provide automatic migrations, you'll need to manage your database schema and handle schema changes manually.



Dapper.NET expects developers to have a solid understanding of SQL and the underlying database structure



Dapper.NET still offers significant advantages, especially in terms of performance and control. 



Will explore Dappet.NET in upcoming articles making a simple CRUD app and looking at pros and CONS of it.

---

[Laravel](https://laravel.com/) is one of the most popular web frameworks for PHP and for good reason. It comes bundled with most common web app needs, including authentication, authorization, localization, and support for multiple database backends including PostgreSQL.

In this guide, were going to deploy a simple [Laravel 10x](https://laravel.com/docs/10.x/) web app using Renders native [PostgreSQL](https://render.com/docs/databases) and Docker support.

Lets get started!

1. [Create](https://dashboard.render.com/new/database) a new PostgreSQL database on Render and copy the internal DB URL to use below.

2. Fork [hoangsvit/laravel-10x-docker](https://github.com/hoangsvit/laravel-10x-docker) and create a new **Web Service** on Render, giving Render permission to access your forked repo.

Select `Docker` for the runtime, and add the following environment variables under the _Advanced_ section:

| KEY | VALUE |
| ------------ | ------------ |
| `DATABASE_URL` | The **internal database URL** for the database you created above. |
| `DB_CONNECTION` | `pgsql` |
| `APP_KEY` | Copy the output of `php artisan key:generate --show` |

Thats it! Your Laravel web app will be live on your Render URL as soon as the build finishes. You can test it out by registering and logging in.

## **Modifying an Existing Laravel App for Render**

The [commit history](https://github.com/hoangsvit/laravel-10x-docker/commits/main) of our sample repo is useful in understanding the modifications needed for an existing Laravel app.

If you havent already, make sure to run `php artisan make:auth` to generate authentication scaffolding for your app.

1. Force HTTPS on all assets served by Laravel to avoid mixed content warnings in the browser. Render already manages and terminates TLS certificates for you, but Laravels [asset helper](https://laravel.com/docs/5.8/helpers#method-asset) needs to be configured to serve everything over TLS. You can do this by following the changes in [Force HTTPS for Laravel](https://github.com/render-examples/php-laravel-docker/commit/27a895df86bc8604c7985af4649bcac8cd2ad1e8).

2. Configure your repo to deploy Laravel using Docker and NGINX. Were building on the [nginx-php-fpm](https://github.com/richarvey/nginx-php-fpm) Docker image as [shown here](https://github.com/hoangsvit/laravel-10x-docker/blob/main/Dockerfile), and adding [php-fpm configuration for NGINX](https://github.com/hoangsvit/laravel-10x-docker/blob/main/conf/nginx/nginx-site.conf) to tie everything together.

3. Finally, add [a deploy script](https://github.com/hoangsvit/laravel-10x-docker/blob/main/scripts/00-laravel-deploy.sh) that will be run when your PHP app starts up.

You should now be able to deploy your existing Laravel app on Render.

6 tips you must know to master bit operation
Tags: programming, bitoperation, beginners, devjournal
Published: 2023-06-14 01:32:00

Bit operation is useful in algorithms and can be much faster than arithmetic operations. 

Here are 6 tips you must know to master it:

1. Before learning bit operation, you should know how decimal converts to binary and how binary turns to decimal. Here is a simple calculation method.


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wnt6xs5g9yv5zg1gbkul.png)


## 2. Shift Arithmetic Left << 

Shift arithmetic left is to move all the binary to the left.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/6nliefgm5v9g3b764ibt.png)


## 3. Shift Arithmetic Right >>

The bitwise right shift moves all the binary digits to the right and removes the extra left digit.

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/npz6uqhtb8qv6vy8e5m3.png)


## 4. Bitwise And 
 Each bit is 1, and the result is 1

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/8rvwewgvwevhzk3df6xk.png)


## 5. Bitwise Or
One of bit is 1, and the result is 1


![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/kpzwzegeqedyb50vilw0.png)


## 6. Bitwise XOR
Each bit is different, and the result is 1

From the below code, we can find that the bitwise XOR is the not carry addition.

Simple Discord Bot That Fetches Data (BS4)
Tags: discord, bot, bs4, api
Published: 2023-06-14 01:15:49

This is a straightforward tutorial that utilizes BS4 to retrieve data from an API and subsequently showcases the fetched information on a Discord server.

To create a Discord bot that fetches information from a website and displays it, you can use a programming language like <u>Python</u> and a library like <u>Discord.py</u>. Here are the basic steps to create the bot:

**1.** Create a project folder and create a Python virtual environment for it. Install Discord.py library and other dependencies like requests, bs4 (BeautifulSoup).

**2.** Create a Discord bot and get its token from Discord Developer dashboard. You can follow the official documentation to create and invite a bot into a Discord server.

**3.** Use the requests library to fetch the HTML content of the targeted website. Use BeautifulSoup to parse the HTML content and extract the required information. Store the extracted information in a variable.

**4.** Use the Discord.py library to define and run a Command that responds to user input. Use the extracted information as the response from the bot. The response can include text and/or images.

**5.** Test the bot by running it in the terminal. Use the bot token to connect it to a Discord server and test its functionality.

Here is a sample code to fetch daily weather information for a city using <u>OpenWeatherMap API</u>:

```python
import requests
from bs4 import BeautifulSoup
import os
import discord
from dotenv import load_dotenv

load_dotenv()

client = discord.Client()
WEATHER_API_KEY = os.getenv("WEATHER_API_KEY")


@client.event
async def on_ready():
    print(f{client.user} has connected to Discord!')


@client.event
async def on_message(message):
    if message.content.startswith('!weather'):
        city = message.content.split("!weather ", 1)[1]

        url = f'https://api.openweathermap.org/data/2.5/weather?q={city}&appid={WEATHER_API_KEY}&units=metric'

        response = requests.get(url)
        data = response.json()
        
        description = data['weather'][0]['description']
        temp = data['main']['temp']
        humidity = data['main']['humidity']
        
        response_text = f"The weather in {city} is {description}. The temperature is {temp}°C and the humidity is {humidity}%."

        await message.channel.send(response_text)


client.run(os.getenv("DISCORD_TOKEN"))
```

This code fetches the weather data from **OpenWeatherMap API** and sends it as a response to the user's message command. The data is displayed in the Discord server channel where the user invoked the command. You can modify this code to fetch and display information from any other website or API.


My intention was to create a user-friendly solution for those who are new to Discord and APIs, and hence, I aimed at keeping it 'simple'. Building the bot through the developer portal involves several intricate steps, which I wanted to avoid.
Harnessing the power of laziness in software development
Tags: softwareengineering, programming, concepts, beginners
Published: 2023-06-14 01:05:15

You are at a buffet dinner, with a plate in your hand and a table full of delicious dishes. Would you choose to bring to your table everything you can carry, or would you simply take a small portion and come back for more if you wish?

If you chose the second option, Great! You're like Sid (a little reference to Ice Age) But don't worry, the truth is that in software development this is a widely accepted and beneficial strategy.

In this context, we refer to a couple of techniques known as _lazy evaluation_ or _lazy loading_, which are ways to use resources efficiently.

## Lazy evaluation

You don't throw all the meat on the grill at once, you better wait for the diners to request it.

In technical terms, lazy evaluation consists of postponing the evaluation of an expression until the results are needed, similar to an on-demand service.

## Lazy loading

This technique is very similar to the previous one, but in this case, the creation or initialization of objects is delayed.

If an event starts at 6 in the evening, there is no reason for you to start getting ready at 6 in the morning.

---

In summary, being "lazy" in software development involves making smart decisions about how and when to use resources, avoiding unnecessary expenses and optimizing performance. It is a strategy that can lead to more efficient code and better use of available resources.

As in our life, it is completely valid to avoid unnecessary efforts in order to concentrate our physical and mental resources on those tasks that really interest us.
