## Casos de uso
Em programação, cada tipo de dado é representado e operado diferentemente na memória. O "casting" é uma técnica usada para informar ao compilador que uma variável deve ser tratada como outro tipo. Isso permite realizar operações específicas com essa variável, além de garantir a compatibilidade com outras partes do código.
Em Kotlin, existe um recurso do compilador chamado **Smart casts** que rastreia verificações de tipos (como com o operador `is`) e infere automaticamente o seu tipo quando necessário.
### Verificação de tipo e inferência
#### Verificação positiva
Ao verificar uma variável com o operador `is`, e se a verificação for bem-sucedida, Kotlin reconhece imediatamente o tipo dessa variável dentro do bloco de código:
```kotlin
class Gato(val emojiGato: String = "🐱")
class Cachorro(val emojiCachoro: String = "🐶")
class Peixe(val emojiPeixe: String = "🐟")
class Pássaro(val emojiPassaro: String = "🐦")
fun falar(animal: Any): String {
return when (animal) {
is Gato -> "Miau ${animal.emojiGato}"
is Cachorro -> "Au au ${animal.emojiCachoro}"
is Peixe -> "Blub blub ${animal.emojiPeixe}"
is Pássaro -> "Pi pi ${animal.emojiPassaro}"
else -> "Não reconhecemos esse animal."
}
}
fun ondeVive(animal: Any) {
if (animal is Gato || animal is Cachorro) {
println("Vive em terra.")
} else if (animal is Peixe) {
println("Vive na água.")
} else if (animal is Pássaro) {
println("Vive no ar e na terra.")
} else {
println("Não reconhecemos esse animal.")
}
}
```
#### Verificação negativa
Usando `!` antes do operador `is`, é possível reagir quando a variável não é do tipo esperado:
```kotlin
class Ave(val canto: String)
class Macaco(val grito: String)
class Reptil(val som: String = "Ssssss")
fun documentarSom(animal: Any) {
if (animal !is Ave) return
print("O som da ave é: ${animal.canto}")
}
// Testando a função
val tucano = Ave("Pi-pi-piu")
documentarSom(tucano) // Saída: "O som da ave é: Pi-pi-piu"
```
#### Limitações com variáveis mutáveis (`var`)
O compilador pode não realizar um Smart Cast se não puder garantir que o valor da variável não mudou entre o momento da verificação e o momento do uso:
```kotlin
open class Animal
class Cachorro() : Animal() {
fun alimentar() = Unit
}
var animal: Animal? = Cachorro()
if (animal is Cachorro) {
animal = null
animal.alimentar() // Erro de compilação: Smart cast para 'Cachorro' é impossível
}
```
### Smart Casts com operadores lógicos
Kotlin vai além e integra a capacidade de "Smart Casts" com operadores lógicos como `&&` e `||`. Isso evita a necessidade de conversões explícitas, tornando o código mais limpo e legível.
```kotlin
open class Animal(val nome: String, val energia: Int = 100)
class Peixe(nome: String, energia: Int, val habitatPreferido: String) : Animal(nome, energia) {
fun explorar() = "está explorando o habitat $habitatPreferido!"
}
class Passaro(nome: String, energia: Int, val tipoBico: String) : Animal(nome, energia) {
fun bicar() = "está usando seu bico $tipoBico para buscar comida!"
}
fun acaoEspecifica(animal: Animal) {
when {
animal is Peixe && animal.energia > 50 -> {
println("${animal.nome} ${animal.explorar()}")
}
animal is Passaro && animal.tipoBico == "afiado" -> {
println("${animal.nome} ${animal.bicar()}")
}
else -> {
println("${animal.nome} não está realizando uma ação específica no momento.")
}
}
}
// Testando a função
val tilapia = Peixe("Tilápia", 60, "lago de água doce")
val aguia = Passaro("Águia", 80, "afiado")
val canario = Passaro("Canário", 50, "pequeno")
acaoEspecifica(tilapia) // Saída: "Tilápia está explorando o habitat lago de água doce!"
acaoEspecifica(aguia) // Saída: "Águia está usando seu bico afiado para buscar comida!"
acaoEspecifica(canario) // Saída: "Canário não está realizando uma ação específica no momento."
```
### Vantagens
- **Sintaxe limpa e código legível**: permite um código mais limpo, direto e legível, evitando repetições de conversões explícitas de tipo.
- **Segurança de tipo**: o compilador realiza o Smart Cast apenas quando é seguro, reduzindo a possibilidade de erros de conversão em tempo de execução.
- **Integração com controle de fluxo**: dentro de controles condicionais como `if`, `else`, `when`, ou loops como `for`, `while`, o Kotlin reconhece e ajusta o tipo da variável de acordo, permitindo o acesso direto a suas propriedades específicas sem necessidade de casting explícito.
### Desvantagens
- **Limitações com Variáveis Mutáveis**: com variáveis mutáveis, Smart Casts pode não ser garantido pelo compilador, já que o tipo pode ter mudado entre a verificação e o uso.
- **Concorrência**: em ambientes com múltiplos threads, o Smart Cast pode apresentar riscos se uma variável for alterada por outro thread após a verificação.
- **Potencial confusão com lógica complexa**: em certas lógicas condicionais, o compilador pode não conseguir inferir o tipo, mesmo que pareça claro para o desenvolvedor.
## Analogia
Ao ouvir o canto de um pássaro específico na floresta, um ornitólogo pode identificar imediatamente a espécie, mesmo sem vê-la. Esse reconhecimento imediato permite ao especialista saber tudo sobre esse pássaro, desde seus hábitos até seu habitat.
O Smart Cast no Kotlin age de forma semelhante, permitindo utilizar o tipo específico assim que identificado, sem necessidade de verificações adicionais.

## Introduction
This documentation outlines the process of implementing caching using Redis in a Node.js Express application. Caching data with Redis helps reduce response times and server load by:
- Storing frequently accessed data in memory
- Optimizing data retrieval by avoiding repetitive requests to external sources
## Prerequisites
- Node.js installed on your machine
- Basic understanding of JavaScript and Express.js
## Redis Docker Installation
To set up Redis using Docker, follow these steps:
1. **Download and Install Docker**:
- Visit the [official Docker website](https://www.docker.com/get-started).
- Download Docker for your operating system and follow the installation instructions provided.
2. **Run Redis Container**: Execute the following command in your terminal to fetch Redis in a Docker container:
```bash
docker run -d --name redis-stack -p 6379:6379 -p 8001:8001 redis/redis-stack:latest
```
This command pulls the latest Redis image from Docker Hub and runs it in a detached mode (`-d`). It also names the container as `redis-stack`, maps the container's port 6379 to the host port 6379 (for Redis), and maps port 8001 to the RedisInsight UI for monitoring Redis data.
**Verify Installation:**
1. Check if the Redis container is running by executing:
```bash
docker ps
```
2. Access RedisInsight by visiting `http://localhost:8001` in your web browser. You should see the RedisInsight dashboard.
3. Connect to the Redis server using the default connection settings (`localhost:6379`). Here's a visual guide on how to connect:
4. After verifying that the Redis container is running and accessing RedisInsight, proceed with the following steps to interact with Redis:
a. Run `docker ps` to check the container IDs.
b. Run the following command to access the Redis container shell (replace `<container_id>` with the actual container ID):
```bash
docker exec -it <container_id> bash
```
c. Once inside the container, run the Redis CLI by executing:
```bash
redis-cli
```
You should now be connected to the Redis server and able to interact with it using the Redis CLI.
## Installation
Ensure Redis server is installed and running. Additionally, install required dependencies for your Express application:
```bash
npm install express axios ioredis
```
## Basic Setup
Begin by setting up a basic Express application that listens on a specific port:
```javascript
const express = require("express");
const axios = require("axios");
const app = express();
app.get("/", async (req, res) => {
const { data } = await axios.get(
"https://jsonplaceholder.typicode.com/photos"
);
return res.json(data);
});
const port = 9000;
app.listen(port, () => {
console.log(`Server is running on port ${port}`);
});
```
## Problem Statement
Fetching data from external APIs directly may result in slow response times due to network latency and server load,here as you can see it took 364 millisecond to fetch the data.
## Solution
Implement caching using Redis to store fetched data temporarily and serve it from the cache for subsequent requests, thereby reducing response times.
Certainly! Here's the updated documentation with the added points:
## Implementation Steps
1. **Initialize Redis Client**
First, create a Redis client to interact with the Redis server. Create a file named `client.js` and add the following code:
```javascript
const { Redis } = require("ioredis");
const client = new Redis();
module.exports = client;
```
2. **Implement Caching Logic**
Modify your route handler to utilize the Redis client for caching. Update your `server.js` file with the following code:
```javascript
const express = require("express");
const axios = require("axios");
const client = require("./client");
const app = express();
app.get("/", async (req, res) => {
const cacheValue = await client.get("to-dos");
if (cacheValue) {
console.log("Cached value");
return res.json(JSON.parse(cacheValue));
}
const { data } = await axios.get(
"https://jsonplaceholder.typicode.com/photos"
);
await client.set("to-dos", JSON.stringify(data));
await client.expire("to-dos", 30);
return res.json(data);
});
const port = 9000;
app.listen(port, () => {
console.log(`Server is running on port ${port}`);
});
```
3. **Observation of Data Fetching Time**
After implementing the caching mechanism, you may notice that the initial data fetching time is higher as it involves fetching data from the external API. However, upon subsequent requests, the data fetching time significantly reduces to approximately 37 milliseconds due to the cached data being served from Redis. This demonstrates the effectiveness of caching in reducing response times and improving overall performance.
4. **Expiration and Renewal**
Note that the cached data expires after 30 seconds (`await client.expire("to-dos", 30)`). Upon expiration, the next request will trigger a fresh data fetch from the external API, refreshing the cache with updated data. This ensures that users receive the most up-to-date information while still benefiting from reduced response times during the cache lifespan.
## Conclusion
By implementing caching with Redis in your Express application, you can significantly improve performance by reducing response times and server load. Caching commonly accessed data helps minimize latency and enhances the overall user experience, especially for frequently accessed resources. | surajvast1 |

It happens every year on March 8th. This day is important because it reminds us to recognize the achievements and progress women have made in various areas like social, economic, cultural, and political fields. It's also a time to think about the work that still needs to be done to achieve gender equality. International Women's Day is a chance to celebrate women's achievements and to raise awareness about the challenges they still face in many parts of the world.
## The Origins of International Women's Day
In the early 1900s, when there were big changes happening in the world, people started talking about a special day for women. This was a time of lots of growth and change, especially in places with a lot of factories and big cities. The first time a 'Women's Day' was celebrated was in the United States in 1909. It was on February 28th, and it was organized by the Socialist Party of America. They wanted to honor the women who had protested in a big strike in New York the year before, in 1908. These women were fighting for better conditions at work.
Then, in 1910, in a city called Copenhagen, there was a meeting of women from many different countries. One woman, Clara Zetkin, who was from Germany and was part of the Socialist group, suggested something big. She said there should be a day for women celebrated all around the world, every year. She thought this day could be used to talk about what women needed and wanted. Everyone at the meeting, which had over 100 women from 17 countries, agreed. And that's how International Women's Day started. It was a way for women to come together and speak out for their rights.
## The Significance of International Women's Day
International Women's Day is a special day celebrated worldwide to honor the progress women have made in society, politics, and economics. It's a time to acknowledge how much has been achieved and recognize the ongoing work needed. This day brings together people from all walks of life, including governments, women's groups, businesses, and charities. Events like talks, rallies, conferences, and marches take place globally, focusing on important issues such as gender equality, women's rights to make choices about their bodies, ending violence against women, and ensuring women have equal economic opportunities. It's a day to raise awareness and show support for women everywhere.
## Why We Celebrate International Women's Day
**Recognition of Women's Achievements**
International Women's Day is a special day to celebrate and recognize the amazing things women have done in our world. It's a time to appreciate the important jobs women have in making our communities, economies, and governments strong.

Sharing **[presentations about Women's Day](https://www.slideegg.com/womens-day-ppt-template)** helps people learn more and understand why this day is important. It's a chance to appreciate what women have accomplished and work towards making sure everyone has equal opportunities and power.
**Raising Awareness About Gender Inequality**
Despite some progress, gender inequality is still a major issue around the globe. International Women's Day serves as a reminder of the ongoing struggle for gender equality and the importance of supporting the rights of women and girls in all areas of life. We need to keep pushing for change and strive for a future where everyone, regardless of gender, has the same opportunities and rights. It's crucial to stand united, spread awareness, and actively work towards building a fairer and more equal world for everyone.
**Solidarity and Unity**
International Women's Day is a day when women from all around the world join together to celebrate their unity and support for each other. It's a special occasion where we recognize the different experiences and backgrounds of women everywhere. We gather to show our commitment to gender equality and women's rights. This day reminds us of the challenges women face and encourages us to work together to overcome them. No matter where we're from or what we do, on International Women's Day, we stand united as sisters, allies, and advocates for a fairer and more just world for all women.
**Inspiring Action**
This special day reminds us to work together for gender equality. It tells us to help women in every way we can and to fight against unfairness. We should support women's progress and challenge stereotypes that stop them from succeeding. We need to speak out when we see unfair treatment. By working together and spreading the word, we can make a world where everyone, no matter their gender, can do well.
## How to Celebrate International Women's Day
There are many ways to celebrate International Women's Day, from participating in events and rallies to supporting women-owned businesses. Here are a few suggestions:
**Educate Yourself and Others:** Use the day as an opportunity to learn more about **[women's rights](https://en.wikipedia.org/wiki/Women%27s_rights)** issues and educate others. Reading books, watching documentaries, or attending seminars can be a great way to start.

```python
>>> import esp
>>> esp.flash_size()
8388608
>>> import micropython
>>> micropython.mem_info()
stack: 736 out of 15360
GC: total: 64000, used: 16096, free: 47904, max new split: 188416
No. of 1-blocks: 346, 2-blocks: 41, max blk sz: 32, max free sz: 2982
>>> import gc
>>> gc.mem_alloc() + gc.mem_free()
252416
>>>
```
flash 只有 8MB, 而載入系統後記憶體看起來只有 252KB, 那我的 psram 跑哪裡去了？
## 解放 psram
這是因為韌體檔有分兩個版本：
- [不支援 8 線 SPI ram 的版本](https://micropython.org/resources/firmware/ESP32_GENERIC_S3-20240222-v1.22.2.uf2)
- [支援 8 線 SPI ram 的版本](https://micropython.org/resources/firmware/ESP32_GENERIC_S3-SPIRAM_OCT-20240222-v1.22.2.uf2)
如果改用支援 8 線 SPI ram 版本的韌體, 得到的結果如下：
```python
>>> import esp
>>> esp.flash_size()
8388608
>>> import micropython
>>> micropython.mem_info()
stack: 736 out of 15360
GC: total: 64000, used: 15440, free: 48560, max new split: 8257536
No. of 1-blocks: 340, 2-blocks: 40, max blk sz: 32, max free sz: 3023
>>> import gc
>>> gc.mem_alloc() + gc.mem_free()
8321536
```
可以看到雖然 flash 還是只有 8MB, 但是可用的記憶體已經暴增到接近 8MB 了, 這表示 psram 已經啟用了。
## 解放 flash
最後要再找回來的就是少掉的 8MB flash, 這主要是因為原本的韌體就是被編譯成 8MB 的空間, 必須要把韌體重新延伸為 16MB, 還好, 已經有善心人心幫我們使用 Python 做好了工具--[mp-image-tool-esp32](https://github.com/glenn20/mp-image-tool-esp32), 安裝方式如下:
1. 從 github 上複製專案：
```
git clone https://github.com/glenn20/mp-image-tool-esp32
cd mp-image-tool-esp32
```
2. 安裝相依的套件:
```
pip install -r requirements.txt
```
利用以下的指令就可以把韌體檔案變成 16MB 空間的大小：
```
python .\mp-image-tool-esp32 -f 16M ..\..\firmware\ESP32_GENERIC_S3-SPIRAM_OCT-20240222-v1.22.2.bin
```
選項 `-f` 就是用來指定韌體大小, 它會產生一個和原始韌體檔案同名但加上 "-16MB" 的檔案, 使用這個韌體檔就可以把 16MB 的 flash 通通解放了：
```python
>>> import esp
>>> esp.flash_size()
16777216
>>> import micropython
>>> micropython.mem_info()
stack: 736 out of 15360
GC: total: 64000, used: 15440, free: 48560, max new split: 8257536
No. of 1-blocks: 340, 2-blocks: 40, max blk sz: 32, max free sz: 3023
>>> import gc
>>> gc.mem_alloc() + gc.mem_free()
8321536

1,783,334 | Remember the Milk Review 2024: Old But Gold | Remember the Milk is one of those applications that I can't remember how many years I've known it,... | 0 | 2024-03-07T13:21:35 | https://blog.productivity.directory/remember-the-milk-review-2024-old-but-gold-67986c201f38 | rememberthemilk, productivity, todolistapp, todolist | [Remember the Milk](https://productivity.directory/remember-the-milk) is one of those applications that I can't remember how many years I've known it, but it has always been a reminder of simplicity and quality for me. Today, I plan to have a short review of the application Old But Gold, as probably the newer generation isn't that familiar with it, but you know, us old friends, we remember it well. I spent a few days with it again, on my Mac and on my Android mobile.
What is Remember the Milk?
==========================
Remember the Milk is a web and mobile application for managing your tasks and time, essentially a [to-do list](https://productivity.directory/category/to-do-lists). It was first created in 2004 in Australia by two friends, and as you can see, it has been helping us manage our tasks for now 20 years. Oh boy, 20 years!
A brief Review
==============
I used the web version on my Mac and the Android version on my mobile phone. Honestly, it felt a bit classic. It still does not have proper social network sign-in options like newer software does, and you need to fill out a form to sign up, but the fact that it didn't ask me to verify my email to use an application that's 20 years old is not bad.
In my opinion, it had the following positive and negative features:
Pros:
-----
- Cross-platform availability: Works on web, Mac, Windows, Linux, Android, and iOS.
- Task synchronization: Keeps tasks updated across all devices.
- Intuitive interface: Easy to use, even for beginners.
- Advanced task management: Allows for prioritization, tagging, and deadlines.
- Integration capabilities: Can integrate with other tools and services.
Cons:
-----
- No social media sign-in: Lacks modern login options like social network integration.
- Classic feel: May seem outdated compared to newer applications.
- Initial setup: Requires filling out a signup form, which might be off-putting for some.
- Limited free version: Some advanced features are locked behind a subscription model.
And now, with that said, will I use it for the long term? Honestly, No. Maybe if I had continued to keep my tasks on it, I would have had to do so, but unfortunately not now!
What platforms is it available for?
===================================
Remember the Milk is fundamentally known for its web version and its synchronization capabilities, but there are also versions available for Windows, Linux, and Mac for desktop systems, and Android and iOS versions for mobile phones. The installation is simple, and you can access all the links from the [Remember the Milk page](https://productivity.directory/remember-the-milk) on the [Productivity Directory](https://productivity.directory/).
It was supposed to be brief, and well, we've come to the end of the post. If you still like to experience the old-school feel or enjoy the cute logo of Remember the Milk, it's not a bad idea to give it a try.

In agile development, the clarity of our understanding about those who use our products—our users—is crucial. User personas help bridge this gap by sketching out fictional yet realistic profiles of our target audience, based on data and insights we gather. These personas aim to deepen our empathy and align our development efforts with user needs. However, as our understanding of users deepens and evolves, traditional methods of creating personas may not fully capture the nuances we’re discovering. There’s a growing need for more detailed, dynamic personas that better represent the complex nature of real users.
This is where the potentials of artificial intelligence, particularly tools like ChatGPT and DALL-E, come into play. By leveraging these tools, we propose enhancing the traditional persona creation process. ChatGPT can help generate detailed personas based on structured prompts, while DALL-E can add a visual dimension by creating images that represent each persona. This combination aims to enrich persona profiles, making them more relatable and useful for agile teams.
This blog post explores how integrating AI tools like ChatGPT and DALL-E into persona creation can provide agile teams with deeper, more actionable insights. Our goal is to show how these tools can complement existing methods, offering a fresh perspective on understanding and engaging with users.
## The Need for Detailed Personas
Understanding the myriad ways in which users interact with products is a cornerstone of successful agile development. The creation of user personas serves as a pivotal step in this process, attempting to distill the essence of diverse user experiences into comprehensible archetypes. Traditionally, these persona profiles stem from a mix of interviews, surveys, and demographic studies. However, as our products and their ecosystems become increasingly complex, the personas built from these conventional methodologies sometimes lack the depth and individuality needed to fully encapsulate the user experience.
A more detailed and vividly constructed persona can bring a wealth of benefits to the agile process. It allows product teams to tailor their work more precisely to user needs, fostering a more empathetic understanding of the audience. Detailed personas paint a richer picture of the user's daily life, their frustrations, goals, and how they interact with technology. This deeper insight enables agile teams to devise solutions that don't just meet basic requirements but truly resonate with users on a personal level.
Yet, achieving this level of detail and authenticity in personas often presents a significant challenge. Traditional data collection methods can be resource-intensive and may not always capture the subtleties of human behavior and motivation. Furthermore, the rapid pace of change in modern technology and societal trends necessitates a dynamic approach to persona creation—one that can adapt and evolve as quickly as our understanding of the user base does.
This is where the potential for innovation lies. By augmenting the traditional persona creation process with advanced AI tools like ChatGPT for textual data generation and DALL-E for visual representation, we can develop richer, more dynamic personas. These AI-enhanced personas not only provide a broader, more nuanced understanding of the user but also offer agile teams a more vibrant and engaging blueprint to guide their development efforts.

1,783,515 | Bridging IoT and Cloud: Enhancing Connectivity with Kong's TCPIngress in Kubernetes | By Rajesh Gheware In the rapidly evolving landscape of Internet of Things (IoT) and cloud... | 0 | 2024-03-07T15:43:44 | https://dev.to/rajeshgheware/bridging-iot-and-cloud-enhancing-connectivity-with-kongs-tcpingress-in-kubernetes-4ogj | kubernetes, kong, unigps, iot | ## By Rajesh Gheware
In the rapidly evolving landscape of Internet of Things (IoT) and cloud computing, organizations are constantly seeking efficient ways to bridge these two realms. The IoT space, particularly in applications like GPS-based vehicle tracking systems, demands robust, seamless connectivity to cloud-native applications to process, analyze, and leverage data in real time. UniGPS Solutions, a pioneer in IoT platforms for vehicle tracking, utilizes Kubernetes Cluster as its cloud-native infrastructure. A key component in ensuring seamless connectivity between IoT devices and cloud services in this setup is Kong's TCPIngress, an integral part of the Kong Ingress Controller.
## **The Role of TCPIngress in IoT-Cloud Connectivity**
Kong's TCPIngress resource is designed to handle TCP traffic, making it an ideal solution for IoT applications that communicate over TCP, such as GPS trackers in vehicles. By enabling TCP traffic management, TCPIngress facilitates direct, efficient communication between IoT devices and the cloud-native applications that process their data. This is crucial for real-time monitoring and analytics of vehicle fleets, as provided by Spring boot based microservices in UniGPS' solution.
### **How TCPIngress Works**
TCPIngress acts as a gateway for TCP traffic, routing it from IoT devices to the appropriate backend services running in a Kubernetes cluster. It leverages Kong's powerful proxying capabilities to ensure that TCP packets are securely and efficiently routed to the correct destination, without the overhead of HTTP protocols. This direct TCP handling is especially beneficial for low-latency, high-throughput scenarios typical in IoT applications.
### **Implementing TCPIngress in UniGPS' Kubernetes Cluster**
To integrate TCPIngress with UniGPS' Kubernetes cluster, we start by deploying the Kong Ingress Controller, which automatically manages Kong's configuration based on Kubernetes resources. Here's a basic example of how to deploy TCPIngress for a GPS tracking application:
```yaml
apiVersion: configuration.konghq.com/v1beta1
kind: TCPIngress
metadata:
name: gps-tracker-tcpingress
namespace: unigps
spec:
rules:
- port: 5678
backend:
serviceName: gps-tracker-service
servicePort: 5678
```
In this example, `gps-tracker-tcpingress` is a TCPIngress resource that routes TCP traffic on port `5678` to the `gps-tracker-service`. This service then processes the incoming GPS packets from the vehicle tracking devices.
### **Security and Scalability with TCPIngress**
Security is paramount in IoT applications, given the sensitive nature of data like vehicle locations. Kong's TCPIngress supports TLS termination, allowing encrypted communication between IoT devices and the Kubernetes cluster. This ensures that GPS data packets are securely transmitted over the network.
To configure TLS for TCPIngress, you can add a `tls` section to the TCPIngress resource:
```yaml
spec:
tls:
- hosts:
- gps.unigps.io
secretName: gps-tls-secret
rules:
- port: 5678
backend:
serviceName: gps-tracker-service
servicePort: 5678
```
This configuration enables TLS for the TCPIngress, using a Kubernetes secret (`gps-tls-secret`) that contains the TLS certificate for `gps.unigps.io`.
Scalability is another critical factor in IoT-cloud connectivity. The deployment of TCPIngress with Kong's Ingress Controller enables auto-scaling of backend services based on load, ensuring that the infrastructure can handle varying volumes of GPS packets from the vehicle fleet.
### **Monitoring and Analytics**
Integrating TCPIngress in the UniGPS platform not only enhances connectivity but also facilitates advanced monitoring and analytics. By leveraging Kong's logging plugins, it's possible to capture detailed metrics about the TCP traffic, such as latency and throughput. This data can be used to monitor the health and performance of the IoT-cloud communication and to derive insights for optimizing vehicle fleet operations.
### **Conclusion**
The integration of IoT devices with cloud-native applications presents unique challenges in terms of connectivity, security, and scalability. Kong's TCPIngress offers a robust solution to these challenges, enabling seamless, secure, and efficient communication between IoT devices and cloud services. By implementing TCPIngress in Kubernetes clusters, organizations like UniGPS can leverage the full potential of their IoT platforms, enhancing real-time vehicle tracking, monitoring, and analytics capabilities. This strategic approach to bridging IoT and cloud not only optimizes operations but also drives innovation and competitive advantage in the IoT space.
In summary, Kong's TCPIngress is a cornerstone in building a future-proof, scalable IoT-cloud infrastructure, empowering businesses to harness the power of their data in unprecedented ways. Through strategic deployment and configuration, TCPIngress paves the way for next-generation IoT applications, making the promise of a truly connected world a reality. | rajeshgheware |

1,783,736 | Frameworks - Analogy | Yesterday, I viewed an AppDev course overview video and an analogy comparing Frameworks to species... | 0 | 2024-03-07T21:01:50 | https://dev.to/sernern/frameworks-analogy-2ob0 | framework | Yesterday, I viewed an AppDev course overview video and an analogy comparing Frameworks to species that share DNA stuck out to me:
"Did you know that humans and chimpanzees share about 98% of their DNA, and it's only 2% that makes us different? Because most of our DNA is just the plumbing of being alive, having a metabolism and being a primate, and then just a little bit makes us distinct and we have exactly the same 98% because we had a common ancestor like, six to 10 million years ago. So similarly, Twitter and Airbnb share much of their code. And really any cloud-based application has the same kind of plumbing. You gotta have a web server, which lets you listen for HTTP requests, you gotta connect to the database. You have to have some rendering engine to render the UI.
Very much the same kind of code for every cloud-based app. And then a little tiny bit makes Twitter distinct from Airbnb. Airbnb has listings, Twitter has tweets. They both have users. Really, that's all that makes them distinct. Most of the plumbing is the same. And in particular, Twitter and Airbnb have a lot of their code is the same because they had a common ancestor." - Professor Raghu Betina
Being a novice to software development, this really helped drive the message home regarding frameworks. No need to reinvent the wheel and all that. | sernern |
1,784,143 | All about routing in React (Part 1) ft. react-router-dom | Here, in this post we are going to learn about the routing in react applications using... | 0 | 2024-03-08T07:23:29 | https://dev.to/jmilind1234/all-about-routing-in-react-part-1-ft-react-router-dom-2fd1 | react, reactrouterdom, javascript, javascriptlibraries | Here, in this post we are going to learn about the routing in react applications using react-router-dom v6.
React-router-dom is a powerful library that is used to handle the routing mechanism in the react application. Its special because in addition to routing it also provides the way to achieve client-side-routing instead of server-side-routing.
Before getting to point on how it provides the client-side-routing, lets discuss in short about client-side-routing and server-side-routing.
So basically in old web apps where hyperlinks (to navigate to other pages) were mentioned using anchor tag, used to make the request to the server and server used to send the page data in response. Even if in react we use anchor tags to navigate we can see that as we click on hyperlinks it will make a request to server and server will return the landing page of our app (where a div with id root is placed), and browser will paint on to that page.
Such kind of routing is called server-side-routing.
Now, another comes client-side-routing, where for getting the content of new page (page to which we want to land), webapp will not make a request to the server.
So how and from where that page content will come from? 🤔
Well in react when we first time hit the domain of our app, all the components are loaded. And these already loaded components will be only served when we navigate to page. Simple !!!
This was about the two types of routing that is used across all web apps.
Now, lets discuss on about "how to start with react-router-dom, to handle routing?"
So, to start with routing we first need to convey our react app all important information about routes and what to show.
This is done by creating routing configuration and wrap our whole app with this routing configuration.
```js
import { Outlet, createBrowserRouter, useLocation } from "react-router-dom";
export const appRouter = new createBrowserRouter([
{
path: "/",
element: <AppLayout />,
errorElement: <Error />,
},
{
path: "/about",
element: <About />,
},
{
path: "/contact",
element: <Contact />,
},
]);
```
So, here basically we mentioned -
1. Number of routes.
2. Path of routes.
3. Component to display on each route.
> Remember - if component is missed than `<Outlet/>` will be rendered, which is by default null (means a white screen)
But this is not enough, because still our app is not aware about the paths or routes. To make our app aware about routes and what to show for each path, we need to wrap whole app inside the router provider.
```js
import { RouterProvider } from "react-router-dom";
import AppLayout from "./src/AppLayout";
import ReactDOM from "react-dom/client";
import { appRouter } from "./src/AppLayout";
const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
<RouterProvider router={appRouter}>
<AppLayout />
</RouterProvider>
);
```
This AppLayout is the starting point of our react-app.
Now our app is aware about all the routes. 🚀
This was about basic routing, but lets say if requested path is not aware than? What to show? How to handle?
No worries, errorElement will take care of it.
In the next post/article we will resume about nested routes, dynamic routing etc. 😊

Undoubtedly, two of the most known programming paradigms are object-oriented programming and functional programming. We can debate all day about the best paradigm, but one thing is clear: they all have pros and cons. I can confidently say that FP and OOP are here to stay for now. So, as a software engineer, getting to grasp FP or OOP concepts is very important, so in this blog post, we will look over one key aspect of object-oriented programming: Objects and Classes.
## What is an Object in OOP?
Objects are the building blocks of an OO program. A program that uses OO technology is a collection of objects.
Object-oriented programming encourages combining our data, functions, or methods in a single object. Unlike some programming paradigms, such as procedural programming, where we write functions to mutate the global scope of data that is probably living elsewhere, OOP encourages us to put our data into a single entity called an object and to write methods or functions that work on these data inside our object.
In its basic form, an object can be defined by two major components: attributes and behaviors. And it can represent real-life entities. For example, we can say that a person is an object.
A person has attributes like eye color, age, height, mouth, legs, etc. A person also has behaviors like walking, talking, breathing, etc. **As said earlier, an object is an entity that contains both attributes and behavior.** Based on this, we can confidently say that a person's behavior works on the attributes of a person. For example, a person's walking behavior will work on the attribute of the legs because the leg does the job of walking.
Programmatically, we can say that the attribute of a person is also known as the concrete data about the person, and the person's behavior is also known as the person's methods programmatically.
Therefore, we can say that a person's eye color, age, and height are the data of the person's object. And walking, talking, and breathing are the methods or behaviors of the person's object.
### Object data
The data stored within an object represents the state of the object. In OO programming terminology, this data is called **attributes**.
We can create an employee object and give it **attributes** such as Social Security numbers, date of birth, gender, phone number, etc. The below example shows an object with the mentioned data or attributes.
```java
public class Employee {
private String name;
private String socialSecurityNumber;
private String dateOfBirth;
private String phoneNumber;
}
```
### Object Behaviours
The behavior of an object represents what the object can do. In procedural languages, the behavior is defined by procedures, functions, and subroutines. In OO programming terminology, these behaviors are contained in methods, and you invoke a method by sending a message to it. In our employee example, consider that one of the behaviors required of an employee object is to set and return the values of the various attributes. Thus, each attribute would have corresponding methods, such as `setGender()` and `getGender()`. In this case, when another object needs this information, it can send a message to an employee object and ask it what its gender is. The below example shows how these methods work.
```java
package com.example.chapter_one;
public class Employee {
...
public void setSocialSecurityNumber(String socialSecurityNumber) {
this.socialSecurityNumber = socialSecurityNumber;
}
public String getSocialSecurityNumber() {
return socialSecurityNumber;
}
}
```
> **Getters and Setters** - The concept of getters and setters supports the concept of data hiding. Because other objects should not directly manipulate data within another object, the getters and setters provide controlled access to an object's data. Getters and setters are sometimes called accessor methods and mutator methods, respectively.
So, let's say we have an `Payroll` object that contains a method called `CalculatePay()` that calculates the pay for a specific employee. Among other information, the Payroll object must obtain the Social Security number of this employee. To get this information, the payroll object must send a message to the Employee object (in this case, the `getSocialSecurityNumber()` method). This means that the Payroll object calls the getSocialSecurityNumber() method of the Employee object. The employee object recognizes the message and returns the requested information.
The diagram below is a class diagram representing the Employee/Payroll system we have been talking about. In the next blog post, we will talk more about classes, so stay tuned.
Each class/object diagram is defined by three separate sections: the name itself, the data (attributes), and the behaviors (methods). For example, the Employee class/object diagram's attribute section contains `SocialSecurityNumber`, `Gender`, and `dateOfBirth`, whereas the method section contains the methods that operate on these attributes.
When an object is created, we say that the objects are instantiated. Thus, if we create three employees, we create three distinct instances of an Employee class. Each object contains its copy of the attributes and methods.
> **An Implementation Issue** - Be aware that there is not necessarily a physical copy of each method for each object. Rather, each object points to the same implementation. However, this is an issue left up to the compiler/operating platform. From a conceptual level, you can think of objects as being wholly independent and having their own attributes and methods.
## Why objects?
In structured or procedural programming, the data is often separated from the procedures(), and often, the data is global, so it is easy to modify data that is outside the scope of your code. This means that access to data is uncontrolled and unpredictable (that is, multiple functions may have access to the global data). Second, because you have no control over who has access to the data, testing and debugging are much more difficult. Objects address these problems by combining data and behavior into one complete package.
So this means that an object can contain entities such as integers and strings, which are used to represent attributes. They also have methods that represent behaviors.
In an object, methods are used to perform operations on the data and other actions. Perhaps more importantly, you can control access to members of an object (both attributes and methods). This means some members, attributes, and methods can be hidden from other objects. For instance, an object called Math might contain two integers called `myInt1` and `myInt2`. Most likely, the Math object also includes the necessary methods to set and retrieve the values of `myInt1 `and `myInt2`. It might also have a method called `sum() `to add the two integers together. Don't worry about the code; we will talk about classes in a different post.
```java
public class Math {
// Here, myInt1 and myInt2 are attributes of the Math object. They are private, meaning they are hidden from other objects.
private int myInt1 = 1;
private int myInt2 = 2;
// This is a method called sum(). It performs an operation on the data (myInt1 and myInt2) by adding them together.
int sum() {
return myInt1 + myInt2;
}
// These are methods used to set the values of myInt1 and myInt2. They control access to these attributes.
public void setInt1(int myIntOne) {
myInt1 = myIntOne;
}
public void setInt2(int myIntTwo) {
myInt2 = myIntTwo;
}
// These are methods used to retrieve the values of myInt1 and myInt2. They also control access to these attributes.
public int getInt1() {
return myInt1;
}
public int getInt2() {
return myInt2;
}
}
```
So basically, if we did not add the getters and setters methods, `myInt1` and `myInt2` will never or cannot be accessed from any place in our code (because they are private attributes/data) except inside the class in which it was declared.
> **Data Hiding** - In OO terminology, data are referred to as attributes and behaviors as methods. Restricting access to certain attributes and/or methods is called data hiding.
## Encapsulation
This brings us to our last sub-topic on objects, **encapsulation**. E**ncapsulation** is the principle that binds together the data and functions that manipulate the data and that keeps both safe from outside interference and misuse. The data of an object is known as its attributes, and the functions/methods that can be performed on that data are known as methods.
By using **encapsulation**, thus combining the data and the methods, we can control access to the data in the Math object. By defining these integers as off-limits, another logically unconnected function cannot manipulate the integers `myInt1` and `myInt2` — only the Math object can do that.
* **Sound Class Design Guidelines** - Remember that it is possible to create poorly designed OO classes that do not restrict access to class attributes. The bottom line is that you can design bad code just as efficiently with OO design as with any other programming methodology. Take care to adhere to sound class design guidelines.
In general, objects should not manipulate the internal data of other objects (that is, `myObject` which is an instance of the `Math` object should not directly change the value of `myInt1` and `myInt2` ). It is usually better to build tiny objects with specific tasks rather than large objects that perform many tasks.
## Conclusion
So, we now know what an object is in OOP: a combination of data/attributes and methods/behaviors in a single entity. We cannot talk about objects without talking about classes, so in the next blog post, we will be demystifying classes in OOP. Stay tuned.

## **7 Steps to Integrate WordPress REST API to your Business Website**
Integrating the WordPress REST API into your business website can significantly enhance its functionality. The following steps can help businesses to utilize the WordPress REST API effectively.
### **Step 1: Enabling the WordPress REST API on your business website**
**Check WordPress version:** You must have a WordPress version of 4.7 or higher to have the REST API by default. WordPress developers can quickly verify and update your WordPress version if needed.
**Review compatibility:** You must ensure compatibility with current themes and plugins. WordPress developers can assess and ensure all website components work seamlessly with the REST API.
### **Step 2: Understanding and implementing authentication methods**
You must decide between Cookie, OAuth, or application passwords for external application integration. For example, insert this snippet to enable application passwords for secure API access.
_add_filter( 'wp_rest_application_passwords_enabled', '__return_true' );_
You may [hire WordPress developers](https://www.capitalnumbers.com/wordpress.php?utm_source=hubpages&utm_medium=Gblog&utm_campaign=hubpages&utm_id=gp0224) to identify the best authentication method for your project's needs and implement it securely.
### **Step 3: Exploring and using WordPress REST API endpoints**
#### **1. Understanding common endpoints:**
Familiarizing yourself with endpoints for Posts, Pages, Users, and more is easier with the expertise of WordPress developers. They can guide you through effectively using these endpoints for your business needs.
#### **2. Making requests:**
Professional developers can craft and execute requests to add, update, retrieve, or delete content via the REST API. This will ensure your business website remains dynamic and up-to-date.
### **Step 4: Creating custom WordPress REST API endpoints**
Custom endpoints can provide tailored solutions for your business. WordPress developers can create and secure these endpoints, enhancing your website's functionality and user experience.
For example, you can create a custom endpoint using the following:
_function register_custom_routes() {_
_register_rest_route('my_namespace/v1', '/featured_posts/', array(_
_'methods' => 'GET',_
_'callback' => 'get_featured_posts',_
_));_
_}_
_add_action('rest_api_init', 'register_custom_routes');_
### **Step 5: Securing Your WordPress REST API**
You must ensure absolute security when integrating the WordPress REST API into your business website. The following best practices can help maintain robust security of your WordPress REST API:
**Enforce SSL (HTTPS) and secure endpoints:** You must ensure all API requests use HTTPS to prevent interception of data in transit. Furthermore, implement WordPress REST API authentication for all sensitive endpoints to restrict access to authorized users only. For external access, use strong authentication methods, such as OAuth or application passwords.
**Data validation, sanitization, and rate limiting:** You must validate all input data to ensure it meets expected formats and sanitize output data to prevent XSS attacks. Furthermore, implement rate limiting to prevent abuse of your API through excessive requests, which can lead to DDoS attacks.
**Monitor and log access for security:** You must keep logs of API access to track usage patterns and potentially suspicious activities, employing logging plugins or custom solutions to enhance monitoring capabilities.
### **Step 6: Testing and Debugging**
You must implement effective testing and debugging to ensure the WordPress REST API functions correctly:
**Use API testing tools and automated testing:** You must leverage tools like Postman or Insomnia to simulate API requests and responses. Furthermore, implement automated testing scripts to test endpoints for common vulnerabilities. Enable WP_DEBUG to log any errors during development and testing. However, you must turn it off on live sites.
**Security scans and peer review:** You must utilize WordPress security plugins or external services to scan your API for vulnerabilities. Furthermore, involve another developer to review code changes to catch potential issues before deployment.
### **Step 7: Deploying and Monitoring**
Deploying changes and monitoring the API's performance is critical to maintaining a secure and efficient digital presence:
**Staging environment testing and gradual rollout:** You must test all changes in a staging environment that previews the live site. Furthermore, consider a beta deployment of new features to limit potential impacts. Always back up your website before making changes to the live site.
**Performance and security monitoring:** You must use tools like New Relic or Kinsta to monitor the API's performance. Furthermore, implement security monitoring tools to detect and alert potential security threats in real-time. Analyze API usage patterns to understand your API usage. Moreover, conduct regular security and performance audits to meet your evolving business needs and security standards.
These practices can help businesses ensure functional, optimized, and secure WordPress REST API integration to meet specific requirements. This will contribute to a robust and reliable digital ecosystem.

1,784,345 | Un script para exportar selectivamente tablas de una BD en AWS | Eres el sysadmin de una empresa y el departamento destinado a mejorar el producto te solicita un... | 0 | 2024-03-08T11:14:42 | https://dev.to/daniconil/un-script-para-exportar-selectivamente-tablas-de-una-bd-en-aws-25l3 | aws, rds, cli, s3 | Eres el sysadmin de una empresa y el departamento destinado a mejorar el producto te solicita un "data lake" donde albergar datos en bruto procedentes de bases de datos para cocinarlos y tomar decisiones. Una de las partes fundamentales de un proyecto así es la extracción de datos, así como su fiabilidad y rapidez en el proceso, que en este caso es diario. Preparas una extracción pero dura demasiado y son gigas y gigas de transferencia que no necesitan, por lo que, finalmente, comprobáis que sólo requieren información de unas 90 tablas de un total de más de 14000 que tiene el proyecto completo. La plataforma está montada en AWS y hemos de ver cómo hacerles llegar esa información totalmente optimizada en tiempo, filtrado y orden. Contamos con una pequeña máquina de EC2 en la infraestructura donde alojamos scripts, por lo que es el sitio idóneo para ello. A partir de aquí, el comando [`start-export-task`](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/rds/start-export-task.html) se convierte en nuestro aliado.
## ¿Qué servicios AWS usaremos?
El listado de servicios que usaremos son los siguientes:
- S3, donde se albergan los datos.
- RDS, la instancia de la base de datos. En este caso, postgres.
- EC2, la máquina donde configuramos el script.
- SNS, el servicio de notificaciones para envíos por correo.
## ¿Qué requisitos necesitamos?
La máquina donde alojaremos el script ha de tener instalado AWS CLI. Se presupone que en una máquina de AWS ha de venir de serie, pero por si queremos hacerlo en otra instancia, ya sea una máquina virtual o en nuestro propio equipo, es muy sencillo, sólo hay que copiar [el siguiente comando proporcionado por AWS](https://docs.aws.amazon.com/es_es/cli/latest/userguide/getting-started-install.html):
```bash
$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install
```
Para comprobar que está todo correcto:
```
~ aws --version
aws-cli/2.7.35 Python/3.9.11 Linux/5.15.0-97-generic exe/x86_64.ubuntu.20 prompt/off
```
Ya lo tenemos todo para dejar preparado un script que haga lo siguiente:
1. Eliminar la copia del día anterior. Los datos no son necesario albergarlos y no pueden mezclarse, por lo que se pueden borrar.
2. Mediante la opción `start-export-task` del comando `rds`, identificar la base de datos y las tablas que queremos exportar con el parámetro `--export-only`. En este caso, hemos puesto 6 tablas.
3. Ha de existir un rol en IAM que tenga acceso de lectura en RDS y escritura en S3, así como la capacidad de crear "buckets".
4. Se hizo un `case` para enviar un correo según el estado en el que se encontraba la exportación. Se hacen comprobaciones cada 120 segundos y mientras fuera distinto de "COMPLETE", vuelve a esperarse 120 segundos antes de otra comprobación del estado. Para conocer el estado, la línea es `identifier postgres-partial-export-$DATE | jq -r `.
```bash
#!/bin/bash

DATE=$(date +%Y-%m-%d-%H-%M)
PRO_DBNAME=database

1,784,416 | Building UI Elements with JSX and Components | Welcome back to the React 101 series! In this chapter, we’ll dive into the fundamental building... | 26,713 | 2024-03-08T11:39:19 | https://dev.to/sayuj/building-ui-elements-with-jsx-and-components-ce7 | react, webdev, javascript, frontend | Welcome back to the React 101 series! In this chapter, we’ll dive into the fundamental building blocks of React: JSX syntax and components. Buckle up and get ready to create your first interactive UI elements!
## What is JSX?
JSX stands for JavaScript XML. It’s a syntax extension that allows you to write HTML-like structures directly within your JavaScript code. This makes it easier to visualize and manage your UI components.
<br>
## Understanding JSX
JSX might look like a strange hybrid of HTML and JavaScript, but it’s a powerful tool that simplifies the process of creating React elements. Let’s break down some key concepts:
<br>
### 1. JSX Elements
JSX allows you to define elements in a way that closely resembles HTML. For example:
```javascript
const heading = <h1>Hello, JSX!</h1>;
```
Here, heading is a JSX element representing an `<h1>` HTML tag.
<br>
### 2. Expressions in JSX
You can embed JavaScript expressions within JSX using curly braces {}. This allows you to dynamically generate content:
```javascript
const name = "John";
const greeting = <p>Hello, {name}!</p>;
```
In this example, the variable name is embedded within the JSX element, resulting in a personalized greeting.
<br>
### 3. JSX and HTML Attributes
JSX attributes are similar to HTML attributes but use camelCase naming convention:
```javascript
const heading = <h1>Hello, JSX!</h1>;
```
<br>
### 4. JSX Represents Objects
JSX gets transpiled into JavaScript objects. For example, the previous JSX element:
```javascript
const heading = <h1>Hello, JSX!</h1>;
```
Gets transformed into:
```javascript
const heading = React.createElement('h1', null, 'Hello, JSX!');
```
<br>
<br>
<br>
## Building Basic UI Elements with React Components
In React, UIs are built using components – reusable, self-contained pieces of code. Components can be either functional or class-based.
<br>
### Functional Components
Functional components are JavaScript functions that take props as arguments and return React elements:
```javascript
const Greeting = (props) => {
return <p>Hello, {props.name}!</p>;
};
// Usage
const App = () => {
return <Greeting name="John" />;
};
```
<br>
<br>
### Class Components
Class components are ES6 classes that extend React.Component:
```javascript
class Greeting extends React.Component {
render() {
return <p>Hello, {this.props.name}!</p>;
}
}
// Usage
const App = () => {
return <Greeting name="John" />;
};
```
<br>
### JSX Fragments
When a component needs to return multiple elements without a parent wrapper, you can use a JSX fragment (<> ... </> or <React.Fragment> ... </React.Fragment>):
```javascript
const MultiElementComponent = () => {
return (
<>
<p>Element 1</p>
<p>Element 2</p>
</>
);
};
```
<br>
<br>
## Remember the Key Points:
- JSX makes UI development more intuitive and readable.
- Components are reusable and encapsulate UI logic.
- Start with basic elements like headings, paragraphs, and images.
- Use props to pass data into your components.
<br>
## Bonus Tip:
Experiment with different JSX elements and components to build interactive prototypes. The more you practice, the more comfortable you’ll become with React’s syntax and component-based approach.
<br>
## Conclusion
JSX and React components are fundamental concepts for building React applications. They provide a declarative and efficient way to describe UIs, making the development process more intuitive and maintainable. In the next parts of the React 101 series,we’ll explore more advanced concepts like state management, event handling, and styling. Stay tuned for more React 101 adventures! | sayuj |

1,784,554 | Build and Deploy: With AWS (Lambda, API Gateway and DynamoDB) using Golang | As of 2024, AWS has officially deprecated the go1.x runtime which came into effect on December... | 0 | 2024-03-14T05:16:38 | https://dev.to/sourjaya/build-and-deploy-rest-api-with-aws-lambda-api-gateway-and-dynamodb-using-golang-58ap | go, aws, dynamodb, tutorial | As of 2024, AWS has officially deprecated the `go1.x` runtime which came into effect on December 31,2023 as mentioned in their official blog [post](https://aws.amazon.com/blogs/compute/migrating-aws-lambda-functions-from-the-go1-x-runtime-to-the-custom-runtime-on-amazon-linux-2/). In this post, let's revisit and look at how you can build a REST API that interacts with DynamoDB and deploy it as a lambda function using Amazon Linux 2023 runtime.
For demonstration, I have only shown two functionalities (fetch and create) in this article. But the complete code with all the functionalities can be found [here](https://github.com/Sourjaya/football-aws-lambda).
There are a few standard ways you can deploy the code as a lambda fucntion, such as using a container(Docker), using serverless framework, using terraform scripts or using AWS SAM.
But using `.zip` file archives to deploy into AWS lambda is one of the more straight forward ways, as mentioned in the official AWS documentation.

##Table of contents
####1. Prerequisites
####2. WRITE the code for the Golang REST API
####3. BUILD the executable file
####4. DEPLOY to AWS
####5. TEST the API
---
<section id="prerequisites">
##1. Prerequisites
###1.1. Golang should be installed in your system.
To check wether `GO` is installed in your system or not use the command `go version` in your terminal. If it is not installed, check the official installation [steps](https://go.dev/doc/install).
###1.2. You should have an AWS account and preferrably logged in as an IAM user.
To sign in as a root or an IAM user follow the [steps](https://docs.aws.amazon.com/signin/latest/userguide/how-to-sign-in.html) mentioned in the official documentation.
###1.3. Use a code editor of your choice.
###1.4. AWS CLI should be installed and configured.
Creating policies and roles as well as deploying the lambda function can be done using the AWS management console as well as the AWS CLI(on the terminal). In case of using [AWS CLI](https://aws.amazon.com/getting-started/guides/setup-environment/module-three/), it should be properly configured.
---
##2. WRITE the code for the Golang REST API
###2.1. Folder Structure
```
└── 📁player-api
└── 📁cmd
└── main.go
└── go.mod
└── go.sum
└── 📁pkg
└── 📁handlers
└── handlers.go
└── response.go
└── 📁player
└── player.go
```
<dl>
<dt><b>NOTE</b></dt>
<dd>You may structure the project folder anyway you want. But it is always a good practice to follow a standard pattern to organize the folder. The above structure is one of the ways you can set up your <code>Go</code> projects.
</dd>
</dl>
---
###2.2 Create your GO Project
Before writing your code you need to setup the directory where you will house your project. After that, open the terminal from the directory, and enter the following command to initialize your project.
```bash
# go mod init [module path]
go mod init github.com/Sourjaya/player-api
```
The go mod init command creates a `go.mod` file to track your code's dependencies. Using your own github repository will provide a unique module path for the project.
Now, in `main.go` write the following code:
{% embed https://gist.github.com/Sourjaya/dd749a46ee42e683475e10ee03ce0c78%}
In `main.go` create a session by passing in the region, then create an instance to the DynamoDB client and use `lambda.Start(handler)` to interact with an internal Lambda endpoint to pass requests to the handler. Then in the `handler` function check for the HTTP method type of the request and call the appropriate functions and return those functions.
Make sure you have an environment variable named `AWS_REGION` in your system. To create the environment variable in Linux, use this command:
```bash
#Open ~/.profile
sudo nano ~/.profile
```
Then write the `export` command at the end of the file:
```bash
#export AWS_REGION=[your_aws_region]
export AWS_REGION=ap-south-1
```
And then press `CTRL+S` to save and `CTRL+X` to exit nano. Now `logout`of your system and log back in.
After you have written the main file, in `pkg/handlers/handlers.go` define and write the functions for each http method type. Write the following code:
{% embed https://gist.github.com/Sourjaya/bcf5ab46900c5ece1f453eb74033b063 %}
The `GetPlayer` function calls `GetPlayerByID` if ID is provided as URL parameter, to fetch the player information with respect to the provided key, else it calls `GetPlayers` to fetch information of all the players in the table. The two functions are available in the `players` package.
The `CreatePlayer` function calls `CreatePlayer` from the player package to add a new player record in the table. Both `GetPlayer` and `Create Player` takes `request`, `tablename` and `client` as function parameters and returns a `response` and a `http status code`. The `Unhandled` function return a `405` status code and a error message.
The response method is responsible to create the `APIGatewayProxyResponse` which will contain appropriate headers, status code and the json response body.
{% embed https://gist.github.com/Sourjaya/2cdb53833c72d0208585e94d74bf0ed8 %}
Now, in `player.go` write the functions that will interact with DynamoDB.
{% embed https://gist.github.com/Sourjaya/dc803b65f36f3f28d0e603d3cfc10291 %}
Function `GetPlayerByID` takes the ID, tablename and client as parameters and returns a `Player` structure containing the player info and an error(if found).
Function `GetPlayers` takes tablename and client as parameters and returns a slice(list) containing info about each player in the database table along with an error(if found).
Function `Create Player` takes request, tablename and client as parameters and returns a `Player` structure containing the player info and an error(if found).

<section id="build">
##3. BUILD the executable file
###3.1 Install the dependencies
Now that you have written all the code needed to build the executable file, it is necessary to install all the dependencies and remove unused modules. To do that, in the terminal execute the command:
```bash
# This will generate go.sum file
go mod tidy
```
###3.2 Create the executable file and zip it
If you are using **Linux/Mac** system execute this command(according to your system architecture use any one of the following commands) to generate the executable:
#####For x86_64 architecture
```bash
GOOS=linux GOARCH=amd64 go build -tags lambda.norpc -o bootstrap main.go
```
#####For arm64 architecture
```bash
GOOS=linux GOARCH=arm64 go build -tags lambda.norpc -o bootstrap main.go
```
#####(Optional) To create a stable binary package for standard C library (libc) versions
```bash
GOOS=linux GOARCH=arm64 CGO_ENABLED=0 go build -o bootstrap -tags lambda.norpc main.go
```
If you are using **Windows** system execute the following set of commands in terminal(using CGO_ENABLED is optional):
#####For x86_64 architecture
```bash
set GOOS=linux
set GOARCH=amd64
go build -tags lambda.norpc -o bootstrap main.go
```
#####For arm64 architecture
```bash
set GOOS=linux
set GOARCH=arm64
go build -tags lambda.norpc -o bootstrap main.go
```
<dl>
<dt><b>NOTE</b></dt>
<dd>Since we are using <code>provided.al2023</code>(Amazon Linux 2023 runtime) we have to name our go executable binary file as <code>bootstrap</code>.
</dd>
</dl>
Now to create the `.zip` file in **Linux/Mac**:
```bash
# zip -jrm [zip file name along with the extension]
# the -m flag deletes the executable
# file which is not needed anymore
zip -jrm football_api.zip bootstrap
```
And to create the `.zip` file in **Windows** :
```
tar -acf football_api.zip bootstrap
del bootstrap
```

<section id="aws">
## 4. DEPLOY to AWS
### 4.1 Create the Lambda Function
### 4.1.1 Using AWS CLI
#### Create Execution Policy
To create an execution policy create a json file with the following content:
**policy.json**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1428341300017",
"Action": [
"dynamodb:DeleteItem",
"dynamodb:GetItem",
"dynamodb:PutItem",
"dynamodb:Query",
"dynamodb:Scan",
"dynamodb:UpdateItem"
],
"Effect": "Allow",
"Resource": "*"
},
{
"Sid": "",
"Resource": "*",
"Action": [
"logs:CreateLogGroup",
"logs:CreateLogStream",
"logs:PutLogEvents"
],
"Effect": "Allow"
}
]
}
```
Now execute the command:
```bash
#Syntax
:'
aws iam create-policy \
--policy-name [policy_name] \
--policy-document file://[file_path/file_name]
'
#Command
aws iam create-policy \
--policy-name lambda-api \
--policy-document file://./policy.json
```
You have successfully created a policy. Remember to note the policy ARN from the response in the terminal. The policy ARN would look something like `arn:aws:iam::111111111111:policy/lambda-api`
#### Create Execution Role and attach Policy
To create an execution role create a json file with the following content:
**trust-policy.json**
```json
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"Service": "lambda.amazonaws.com"
},
"Action": "sts:AssumeRole"
}
]
}
```
Now execute the command:
```bash
#Syntax
:'
aws iam create-role --role-name [role_name] \
--assume-role-policy-document file://[file_path/file_name]
'
#Command
#Remember to note the role ARN as well.
aws iam create-role --role-name lambda-api \
--assume-role-policy-document file://./trust-policy.json
```
Now, we have to attach the `policy` we created to this `role`.
To do that use this command:
```bash
#Syntax
:'
aws iam attach-role-policy --role-name [role_name] \
--policy-arn [policy_arn that was noted]
'
#Command
aws iam attach-role-policy --role-name lambda-api \
--policy-arn arn:aws:iam::111111111111:policy/lambda-api
```
#### Create Lambda function
To create a lambda function using AWS CLI use the following command in the terminal:
```bash
# Syntax
:'
aws lambda create-function --function-name [lambda_function_name] \
--runtime provided.al2023 --handler [handler_name] \
--architectures [your_system_architecture] \
--role arn:aws:iam::[aws_id]:role/[role_name] \
--zip-file fileb://[zip_file]
'
# Command
aws lambda create-function --function-name new-lambda \
--runtime provided.al2023 --handler bootstrap \
--role arn:aws:iam::111111111111:role/lambda-api \
--zip-file fileb://football_api.zip
```
<dl>
<dt><b>NOTE</b></dt>
<dd>
<ul>
<li>The <code>--architectures</code> option is only required if you're using arm64. The default value is x86_64.</li>
<li>For <code>--role</code>, specify the Amazon Resource Name (ARN) of the execution role.</li>
<li>I have not shown my AWS ID in any of the above commands. Put your 12-digit AWS ID in place of those 1's and use it. </li>
<li>Replace <code>'\'</code> from the commands with <code>'^'</code> if you are using a <b>Windows</b> system </li>
</ul>
</dd>
</dl>

### 4.1.2 Using AWS Management Console
Login to the management console. And follow the steps.
#### Create Execution Policy
To create an execution policy:
1. Select _**Security credentials**_ from the dropdown when you click on your account at the top right.
2. Go to _**Access management-->Policies**_ .
3. Click on _**Create Policy**_ button.
4. Now in _**Policy editor**_ and under _**JSON**_ tab put the content of `policy.json` file.
5. Now click on _**Next**_ and give it a Name(lambda-api) and Description(optional) and then click _**Create Policy**_.
You have successfully created a policy.
#### Create Execution Role and attach Policy
To create an Execution Role:
1. Go to _**Access management-->Roles**_ .
2. Under _**Trusted entity type**_ select _**AWS service**_ and under _**Use case**_ select _**lambda**_ and click _**Next**_.
3. In _**Add permissions**_ search and select the policy(lamda-api) you created and click _**Next**_.
4. Now give it a Name(lambda-api) and click **Create role**.
#### Create Lambda function
To create a lambda function using AWS Console follow the steps:
1. Search _**Lambda**_ in the search box and go to the `Functions` page.
2. Click on _**Create Function**_ button.
3. Give the function a Name(new-lambda), select the Runtime(Amazon Linux 2023) and select the Architecture(x86_64 in my case).
4. Under _**Permissions**_ tab change the execution role.
5. You may choose the role that was created from _**Use an existing role**_ or choose **_Simple microservice permissions_** from **Policy templates** by selecting _**Create a new role from AWS policy templates**_ .
6. Now after you click on _**Create function**_ you have to _**Edit**_ the _**Runtime Settings**_ and change handler name to `bootstrap`.
7. The only step that is left is to upload the _**Code Source**_ which will be the `zip` file that was created.
You have successfully created a Lambda function.
### 4.2 Create a table in DynamoDB
We can create a table in DynamoDB using both the AWS CLI or the Console. I prefer to use the Console, as the table attributes are created through code. But if you want to learn how to use AWS CLI to use DynamoDB follow this [link](https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/getting-started-step-1.html).
To create a table using DynamoDB:
1. Search _**DynamoDB**_ in the search box and go to the `Tables` page.
2. Click on _**Create Table**_ and give the table a Name(you have mentioned in your code).
3. Enter _**Partition Key**_(which will be the primary key). In this case it will be the `id` field.
4. Click on _**Create Table**_.
### 4.3 Create a REST API in APIGateway
To create the API:
1. Search _**API Gateway**_ in the search box and in the `API` page click on _**Create API**_.
2. Now scroll down and click _**Build**_ on _**REST API**_ tab.
3. Under _**API details**_ tab select _**New API**_ and then give tha API a name and select `Regional` in _**API endpoint type**_.
4. After you click on _**Create API**_, the page will be redirected to _**Resources**_ under the API. Click on _**Create method**_ under _**Methods**_ tab.
5. Select `ANY` as _**Method type**_, Chose the _**Lambda function**_ name(or alias) and the region(in my case it was `ap-south-1`) .
6. Enable the _**Lambda proxy integration**_ and _**Default timeout**_ options and click on _**Create method**_.
7. The final step is to click on _**Deploy API**_, create a _**New Stage**_(staging) and _**Deploy**_. Make sure to note the `Invoke URL` which will look like this: `https://unp18fmgcc.execute-api.ap-south-1.amazonaws.com/staging`.
You will see something like this:
You have successfully deployed a REST API using a serverless stack. Now we will look at how we can Test the API and wether the endpoints are working or not.
---
</section>
<section id="test">
##5. TEST the API
The API will have the following Endpoints:
| HTTP Method | EndPoint | Description |
|-------------|------------------|--------------------------|
| GET | /staging | Retrieve all players. |
| GET | /staging?id={ID} | Retrieve a player by ID. |
| POST | /staging | Create a new player. |
You can Test your API using the good old `curl` command. The commands are given below:
#### 1. Get All Players.
```bash
#Syntax
#curl -X GET [Invoke URL]
#Command
curl -X GET https://unp18fmgcc.execute-api.ap-south-1.amazonaws.com/staging
```
#### 2. Get Player by ID.
```bash
#Syntax
#curl -X GET [Invoke URL]?id=[id]
#Command
curl -X GET https://unp18fmgcc.execute-api.ap-south-1.amazonaws.com/staging?id=7ff4d720-a825-4727-ad95-e37dd62b90cf
```
#### 3. Create Player.
```bash
#Syntax
:'
curl --header "Content-Type: application/json" --request POST --data [JSON data] [Invoke URL]
'
#Command
curl --header "Content-Type: application/json" --request POST --data '{"firstName": "Luis", "lastName": "Suarez", "country":"uru","position":"FW","club":"Inter Miami"}' https://unp18fmgcc.execute-api.ap-south-1.amazonaws.com/staging
```
**Postman** can also be used to Test the endpoints and you can make a postman collection similar to:

Quando você pensa em mulher na tecnologia, o que vem a sua mente? E essa pergunta é importante para todes.
O seu pensamento de diversidade está incluindo quais mulheres? As brancas? As negras? As indígenas? As pardas? As amarelas? As mulheres dos mais diversos tipos de corpos?
Você só considera as mulheres cis? E as mulheres trans? Você lembra das mulheres com deficiência? Tem considerado as mulheres mais velhas e não apenas as mais jovens? E as mulheres que são mães? Ou que querem ser mães? Ou que não querem ser?
E aquelas que querem começar uma nova carreira na área, que tipo de suporte e oportunidade elas tem recebido da sociedade, das comunidades e do mercado?
Já parou para pensar se a sua homenagem ao dia das mulheres e às mulheres da tecnologia inclui aquelas que são do norte ou nordeste do país? Ou de quaisquer outras regiões do Brasil e do mundo?
Você homenageia também, com as suas palavras e emoções, as mulheres que creem em religiões diferentes das suas? Culturas e verdades diferentes das suas? Você se lembra de todas as raças? Todas as cores? Todas as histórias e experiências diferentes das suas?
E as mulheres LGBTQIAP+? Também fazem parte de toda a compaixão que você demonstra todo dia 8 de março ou elas estão apenas nas suas piadas sexistas com aquele seu grupinho racista, machista e misógino?
Quando foi que você se lembrou, de verdade, das mulheres de baixa renda? As que sofrem com a miséria das mais diversas formas? As que sofrem constantes violências? E as mulheres que você chama de loucas só porque elas lutam para conquistarem algo que já deveria ser delas?
Muitas pessoas por aí perguntam o que fazer para solucionar "o problema da falta de diversidade nas empresas" e em tantos outros lugares na sociedade. Como mudar a diversidade se raramente conseguimos encontrar lugares nos quais realmente nos sentimos pertencentes? Como mudar a diversidade se nem mesmo a nossa vida é respeitada? Como mudar a diversidade se não fazemos o exercício de perceber quem está ao nosso lado?
Ainda temos raízes muito profundas para quebrar. E apenas um "feliz dia da mulher" não alimenta a diversidade. Apenas uma "vaga para mulheres na empresa" não é uma oportunidade saudável. Precisamos ir muito além como sociedade para que deixemos de ser vistas como nos veem hoje: ou somos um nada, ou somos alguém para servir de token para o seu falso papo de diversidade, ou somos alvo de todo tipo de violência.
Como já disse, ainda temos raízes muito profundas para quebrar. **Que continuemos sendo todas loucas o suficiente para quebrarmos cada uma dessas raízes.**

1,785,155 | ApplicationContext, DispatcherServlet, ContextLoaderListener | A context indicates an instance of Spring bean container. If we want a DispatcherServlet to dispatch... | 0 | 2024-03-09T08:34:30 | https://dev.to/rudeh1253/applicationcontext-dispatcherservlet-contextloaderlistener-1jgb | spring, webdev, java | A context indicates an instance of Spring bean container. If we want a DispatcherServlet to dispatch the request to beans annotated with @Controller (i.e., controllers), we should provide a context containing controller beans, in other words, we should pass the location of metadata of Spring context to DispatcherServlet so that it can generate his Spring context. Typically, Spring context DispatcherServlet has contains beans related to Web MVC, such as controllers or rest controllers (beans annotated with @Controller or @RestController).
Each DispatcherServlet has one Spring context its own. If you want some beans to be shared across your web application, it doesn't be achieved by registering beans on the DispatcherServlet context.
In that case, you can register your beans on the context included in ContextLoaderListener, which is so called bootstrap context since it is root of Spring contexts of web application. DispatcherServlet contexts are children of the bootstrap context. For a beans in parent context, it is visible to the child context, but not vice versa.
Once you register your beans into the bootstrap context in ContextLoaderListener, your DispatcherServlet can access the beans.
Registering ContextLoaderListener in web.xml:
```
<listener>
<listner-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<!-- By default, ContextLoaderListener uses XmlWebApplicationContext
<context-param>
<param-name>contextClass</param-name>
<param-value>org.springframework.web.context.support.XmlWebApplicationContext</param-value>
</context-param>
-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:spring-config/context-*.xml</param-value> <!-- For instance -->
</context-param>
```
ContextLoaderListener uses ServletContext to get the information where the metadata was placed. | rudeh1253 |

Today, we're... | 0 | 2024-03-09T13:45:05 | https://dev.to/whoisfisayo/how-to-center-a-div-4nb3 | javascript, beginners, tutorial, programming | ## **Center That Div! 💻 The Never-Ending Quest in Web Development**
Hey Dev Fam! Today, we're tackling one of the age-old questions that haunt every coder's dreams: How the heck do we center a div?! 😱 It's the stuff of legends, the Holy Grail of web development, and I'm here to guide you through this epic journey. Strap in, it's gonna be a wild ride! 🎢
**The Conundrum Begins**
Picture this: you're staring at your screen, determined to conquer the chaos of code, when suddenly, you encounter your first roadblock. Your div is stubbornly refusing to budge from the corner of the screen, like a petulant child unwilling to share its toys. 😤 Thus begins our epic quest for div-centering mastery!
**The Trials and Errors**
You try every trick in the book—margin: auto, text-align: center, even sacrificing a few keyboard keys to the coding gods—but to no avail. The div remains steadfast, mocking your efforts with its unwavering defiance. 🙅♂️ But fear not, dear coder, for every setback is just another step on the path to greatness!
*A Glimmer of Hope**
Just when you're about to throw your laptop out the window in frustration, a beacon of light appears on the horizon. You stumble upon a forum thread, a hidden gem of wisdom amidst the chaos of the internet. Could this be the answer you've been searching for all along? 🤔
**The Revelation**
With trembling hands and bated breath, you implement the sacred incantation:
**Step 1: The Basics**
Ah, the humble beginnings of our epic quest! First things first, let's lay the groundwork in HTML. You'll need a trusty div, of course. Here's a simple example to get you started:
```
`<div class="center-me">
<!-- Your awesome content goes here! -->
</div>`
```
**Step 2: The CSS Magic**
Now, let's sprinkle some CSS fairy dust to elevate that div to center stage. Prepare to be dazzled by the magic:
```
`.center-me {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
}`
```
Boom! With just a few lines of CSS, your div is now perfectly centered on the screen. Talk about a game-changer! 🎯
**Step 3: But Wait, There's More!**
Hold on to your hats, folks, because we're not done yet! Ever heard of future-proofing your div centering? That's right, we're adding a sprinkle of JavaScript to ensure your div stays centered even if the user decides to resize the window. Here's the secret sauce:
```
`window.addEventListener('resize', () => {
document.querySelector('.center-me').style.transform = 'translate(-50%, -50%)';
});`
```
And just like that, your div will stay perfectly centered, no matter what the digital winds may bring! 🙌
**Victory Dance**
And lo and behold, like a phoenix rising from the ashes, your div ascends to the center of the screen, triumphant and glorious! 🎉 You dance a victory jig around your room, celebrating your newfound div-centering prowess with reckless abandon.
**Paying It Forward**
But your journey doesn't end here, my friend. No, it's only just beginning. Armed with your newfound knowledge, you vow to help your fellow devs navigate the treacherous waters of div-centering woes. Together, we shall conquer the digital frontier, one centered div at a time! 💪🚀 | whoisfisayo |
1,785,376 | Leveraging Machine Learning to Streamline Code Generation | In the rapidly evolving tech landscape, machine learning (ML) is not just revolutionizing traditional... | 0 | 2024-03-09T13:59:26 | https://dev.to/nitin-rachabathuni/leveraging-machine-learning-to-streamline-code-generation-19bj | webdev, javascript, programming, machinelearning | In the rapidly evolving tech landscape, machine learning (ML) is not just revolutionizing traditional sectors but also transforming how we develop software. Code generation, once a manual and tedious task, is now at the forefront of this transformation. By leveraging ML, developers can streamline their workflows, reduce human error, and accelerate the development process.
The Role of Machine Learning in Code Generation
Machine learning models, especially those trained on vast datasets of code, understand programming languages' syntax and semantics. They can generate code snippets, entire functions, or even more complex structures based on natural language descriptions or other forms of input. This capability is not just about saving time; it's about making advanced programming accessible to a wider range of people.
Tools and Technologies
Several tools and platforms are making waves in this area. OpenAI's Codex, which powers GitHub Copilot, is a prime example. It suggests code and functions based on the context provided by the developer, significantly speeding up the coding process. Similarly, Google's AlphaCode and Facebook's TransCoder show promising results in code generation and translation, respectively.
Benefits of ML-Driven Code Generation
Increased Efficiency: By automating routine coding tasks, developers can focus on more complex and creative aspects of software development.
Enhanced Learning: Beginners can learn programming practices and syntax more effectively by analyzing the code generated by ML models.
Code Quality Improvement: Advanced ML models can suggest optimizations and improvements to existing code, enhancing performance and maintainability.
Challenges and Considerations
While the potential is immense, there are challenges. Reliance on ML for code generation can lead to generic solutions that may not be optimized for specific use cases. Developers must also ensure that the generated code is secure and free from vulnerabilities, which requires thorough review and testing.
Practical Example: A Simple Code Generator
Let's illustrate the concept with a Python example. We'll create a basic machine learning model that generates HTML code for a web page layout based on a simple description.
Prerequisites:
Python 3.x
TensorFlow and Keras for building the ML model
A dataset of HTML code snippets paired with descriptions (for training the model)
Note: This is a simplified example to demonstrate the concept. In practice, you'd need a more sophisticated model and a larger dataset.
```
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Dense, Embedding
from tensorflow.keras.preprocessing.text import Tokenizer
from tensorflow.keras.preprocessing.sequence import pad_sequences
# Example dataset (in practice, use a much larger dataset)
descriptions = ["header with navigation links", "main content area", "footer with copyright information"]
html_snippets = ["<header><nav></nav></header>", "<main></main>", "<footer></footer>"]
# Tokenizing the descriptions
tokenizer = Tokenizer(num_words=1000, oov_token="<OOV>")

1,785,419 | How to Securely Set Up a GitHub Access Token in Git | How to Use GitHub Access Tokens for Secure Git Operations GitHub access tokens provide a... | 0 | 2024-03-09T15:31:12 | https://dev.to/sh20raj/how-to-securely-set-up-a-github-access-token-in-git-1fce | ## How to Use GitHub Access Tokens for Secure Git Operations
GitHub access tokens provide a secure way to interact with your GitHub repositories without needing to use your GitHub password. They are especially useful when using Git on the command line, in continuous integration (CI) workflows, or in any situation where you want to automate Git operations securely.
### What is a GitHub Access Token?
A GitHub access token is a randomly generated string that serves as a substitute for your GitHub password. It allows you to perform Git operations over HTTPS without the need to enter your password each time. This is particularly advantageous for automation and scripting, as well as enhancing security by keeping your password hidden.
### Generating a GitHub Access Token
To generate a GitHub access token, follow these steps:
1. **Navigate to GitHub Settings**:
- Log in to your GitHub account.
- Click on your profile icon in the top-right corner, then select "Settings" from the dropdown menu.
2. **Access Developer Settings**:
- In the left sidebar, click on "Developer settings".
3. **Generate New Token**:
- Click on "Personal access tokens".
- Then, click the "Generate new token" button.
4. **Configure Token**:
- Enter a descriptive note to remind you of the token's purpose.
- Select the scopes or permissions your token needs. For basic Git operations, the `repo` scope is usually sufficient.
- Click "Generate token".
5. **Copy and Store the Token**:
- GitHub will display your new access token. **Important:** Copy this token and store it securely. You won't be able to see it again!
- Treat this token like a password. Do not share it publicly or include it in code repositories.
### Using the Access Token in Git
Now that you have your GitHub access token, you can use it in Git for secure operations. Here's how to set it up:
#### 1. Configure Git
Open your terminal and run the following commands, replacing `YOUR_TOKEN_HERE` with your actual access token:
```bash
git config --global credential.helper cache
git config --global credential.helper 'cache --timeout=3600'
git config --global user.name "your_username"
git config --global user.email "your_email@example.com"
git config --global user.password "YOUR_TOKEN_HERE"
```
- Replace `"your_username"` and `"your_email@example.com"` with your GitHub username and associated email.
- The `credential.helper cache` command caches your credentials for an hour, so you don't need to re-enter your token frequently.
- The `user.password` configuration is not standard, but it might be accepted by some Git clients.
#### 2. Verify Configuration
You can verify that your configuration has been set correctly by running:
```bash
git config --global --list
```
This will display your global Git configuration, including your username, email, and access token.
#### 3. Using the Token
The next time you interact with a GitHub repository over HTTPS, Git will use your access token for authentication. If it prompts you for a password, enter your access token instead.
### Benefits of Using Access Tokens
- **Enhanced Security**: Access tokens are more secure than passwords because they are random strings, reducing the risk of unauthorized access.
- **Automation**: Tokens are useful for automated scripts, CI/CD pipelines, and other tools where entering passwords is impractical.
- **Scalability**: Tokens are tied to your account, allowing you to control access at a granular level by revoking specific tokens.
### Conclusion
GitHub access tokens provide a secure and convenient way to authenticate Git operations without exposing your password. By following the steps outlined above, you can generate an access token, configure Git to use it, and enjoy a more streamlined and secure Git workflow.
Remember to keep your access token secure, treat it like a password, and never share it publicly. If you suspect your token has been compromised, regenerate it in your GitHub account settings. | sh20raj | |
1,785,466 | Gerenciamento de estados de forma minimalista no React Native com Jotai | Nesse artigo, vou falar sobre o Jotai, uma biblioteca de gerenciamento de estados globais para React.... | 0 | 2024-03-09T17:12:34 | https://dev.to/lumamontes/gerenciamento-de-estados-de-forma-minimalista-no-react-native-com-jotai-5fle | react, reactnative |
Nesse artigo, vou falar sobre o Jotai, uma biblioteca de gerenciamento de estados globais para React. Vou explicar o que é, como instalar e como usar, com exemplos práticos.
## O que é Jotai?
Jotai é uma biblioteca de gerenciamento de estados globais para React, destacando-se pela simplicidade e facilidade de uso. Ela é capaz de escalar desde aplicações simples até aquelas com estados mais complexos, graças à sua flexibilidade e performance. Com apenas 2kb, a API principal é extremamente leve, contribuindo para a eficiência da biblioteca. A Jotai adota uma abordagem 'atômica' para o gerenciamento de estados globais.
Nesse exemplo vou estar utilizando Jotai em React Native com Typescript, porém o Jotai é compatível com outros frameworks como Next.js, Gatsby, Remix e Waku.
## Instalação
Para instalar o Jotai, basta rodar o comando no seu terminal do seu projeto React Native:
```bash
npm install jotai
```
ou
```bash
yarn add jotai
```
ou
```bash
pnpm add jotai
```
## Exemplo
O Jotai tem uma estrutura definida por átomos, que são os estados. Pra qualquer estado ou variável global que você quiser criar, você vai criar um átomo.
No meu exemplo, digamos que eu tenha um app financeiro e eu queira 2 estados globais, que vou precisar acessar em vários lugares do app:
- um número inteiro que irá armazenar o saldo do usuário.
- um booleano que vai controlar se o saldo financeiro está visível ou não.
Logo, eu vou criar 2 átomos, um para cada estado que eu quero armazenar. Uma boa prática é criar um arquivo separado somente para a criação dos átomos, para que fique mais organizado. No meu exemplo, na raiz do projeto mesmo irei criar um arquivo chamado `Atoms.ts` que vai conter todos os átomos.
```tsx
import { atom } from 'jotai';
export const balanceAtom = atom(0);
export const isBalanceVisibleAtom = atom(false);
```
Conforme o exemplo acima, usei a função `atom` do Jotai para criar um átomo que representa um estado global.
Essa função `atom` recebe um parâmetro que é o valor inicial do átomo, e dependendo do tipo desse valor, o Jotai já consegue inferir o tipo do átomo.
Por exemplo, no meu caso, o átomo `isBalanceVisibleAtom` é um booleano, então eu passei um `false` como valor inicial. E o átomo `balanceAtom` é um número, então eu passei 0 como valor inicial.
E é isso! Agora eu posso chamar esses átomos em qualquer lugar do meu app, para visualizar e/ou alterar o valor dos mesmos utilizando o hook `useAtom` do Jotai.
Primeiro, vou criar um componente que irá exibir o saldo do usuário e um botão para adicionar um valor de 10 ao saldo.
```tsx
import { View, Text, Button } from 'react-native';
import { useAtom } from 'jotai';
import { balanceAtom } from '@/Atoms';
export default function Balance(){
const [balance, setBalance] = useAtom(balanceAtom);
return (
<View>
<Text>Saldo: {balance}</Text>
<Button title="Adicionar 10" onPress={() => setBalance((prev) => prev + 10)} />
</View>
)
}
```
Conforme o exemplo acima, utilizamos o hook `useAtom` do Jotai, que irá retornar duas funções que são parecidas com o useState do React. A primeira função será o valor desse átomo, e a segunda é uma função pra atualizar o valor desse átomo.
Nesse caso, quero exibir em tela o saldo do usuário, então no useAtom passei como parâmetro o `balanceAtom` que é o átomo que defini para representar esse estado.
```
useAtom(balanceAtom);
```
E como retorno, eu recebo o valor do saldo e a função para atualizar o saldo.
```
const [balance, setBalance] = useAtom(balanceAtom);
```
Agora, vamos criar um componente de header que irá exibir um botão para mostrar ou esconder o saldo do usuário.
```tsx
import {View, Text, Button} from 'react-native';
import { useAtom } from 'jotai';
import { isBalanceVisibleAtom } from '@/Atoms';
export default funcion Header(){
const [isBalanceVisible, setIsBalanceVisible] = useAtom(isBalanceVisibleAtom);
return (
<View>
<Text>Bem vindo!</Text>
<Button title="Mostrar saldo" onPress={() => setIsBalanceVisible(!isBalanceVisible)} />
</View>
)
}
```
Agora, posso atualizar o componente Balance para que ele só seja exibido se o saldo estiver visível.
```tsx
import { View, Text, Button } from 'react-native';
import { useAtom } from 'jotai';
import { balanceAtom, isBalanceVisibleAtom } from '@/Atoms';
export default function Balance(){
const [balance, setBalance] = useAtom(balanceAtom);
const [isBalanceVisible] = useAtom(isBalanceVisibleAtom);
return (
<View>
<Text>Saldo: {isBalanceVisible ? balance : '***'}</Text>
<Button title="Adicionar 10" onPress={() => setBalance((prev) => prev + 10)} />
</View>
)
}
```
Dessa forma, o saldo só será exibido se o usuário clicar no botão "Mostrar saldo" do componente Header.
E é isso! Agora eu tenho 2 estados globais que posso acessar e posso atualizar de qualquer lugar do meu app. E o melhor de tudo, o Jotai já cuida de atualizar todos os componentes que estão usando esses átomos, lidando por trás dos panos otimização, memorização, e re-renders desnecessários.
## Conclusão
o Jotai é uma biblioteca fantástica que simplifica muito o gerenciamento de estados do React. Além dos exemplos que mostrei, o Jotai tem várias outras funcionalidades que podem ser muito úteis, como um pacote responsável por fazer cache de átomos, fazer transições de estados, integração com outras ferramentas como React Query, e muito mais.

Choosing the right niche is the foundational step in building a successful affiliate marketing business. Your niche determines the audience you’ll be targeting, the products you’ll be promoting, and ultimately, the potential for profitability. Here are some essential tips for selecting the perfect niche for your affiliate marketing endeavors:
1. Passion and Interest: Start by identifying topics or industries that genuinely interest you. Your passion for the niche will fuel your motivation to create content, engage with your audience, and stay committed to your affiliate marketing efforts over the long term.
2. Expertise and Knowledge: Assess your expertise and knowledge in various subjects. Consider niches where you have valuable insights, skills, or experience to share.

By gaining insights into your audience’s motivations and behaviors, you can identify products that align with their needs and interests.
2. Conduct Market Research: Research the market landscape within your niche to identify popular products and trends. Use online tools such as Google Trends, Amazon Best Sellers, and social media analytics to discover products that are in high demand and trending among your target audience.
3. Evaluate Product Quality and Reputation: Assess the quality and reputation of potential affiliate products before promoting them to your audience. Look for products from reputable brands with positive customer reviews and testimonials. Avoid promoting products that are known for poor quality, unethical practices, or a history of customer complaints.
4. Check Affiliate Programs and Commission Rates: Explore affiliate programs offered by brands or affiliate networks within your niche. Research the commission rates, payment terms, and cookie durations of different affiliate programs to determine which ones offer the best earning potential. Look for programs with competitive commission rates and generous cookie durations to maximize your earnings per sale.
5. Consider Product Fit and Relevance: Choose products that are closely related to your niche and audience’s interests. Consider whether the product solves a specific problem or fulfills a need for your audience. Promoting products that are relevant and valuable to your audience increases the likelihood of conversions and enhances your credibility as a trusted affiliate marketer.
6. Review Sales Performance Data: If possible, review sales performance data for potential affiliate products to assess their conversion rates and earning potential. Look for products with a history of high conversion rates and consistent sales performance. Analyze factors such as average order value, conversion rate, and customer retention to gauge the product’s profitability.
7. Test and Experiment: Experiment with promoting different products to your audience and track the results to identify which ones perform best. A/B tests different product offerings, promotional strategies, and messaging to optimize your affiliate marketing campaigns for maximum effectiveness. Continuously monitor your results and adjust your approach based on performance data and feedback from your audience.
8. Consider Product Lifecycle and Seasonality: Take into account the product lifecycle and seasonality factors when selecting affiliate products. Some products may experience fluctuations in demand based on seasonal trends, holidays, or industry-specific events. Choose products with year-round appeal or consider diversifying your product offerings to accommodate seasonal variations in demand.
9. Stay Updated on Industry Trends: Stay informed about industry trends, new product launches, and emerging technologies within your niche. Subscribe to industry newsletters, follow relevant blogs and social media accounts, and attend industry conferences or webinars to stay updated on the latest developments. Being aware of upcoming trends and innovations can help you identify new affiliate opportunities and stay ahead of the competition.
10. Seek Feedback and Recommendations: Don’t hesitate to seek feedback and recommendations from your audience, peers, and fellow affiliate marketers. Engage with your audience through surveys, polls, and social media interactions to understand their preferences and gather insights into which products they would like to see promoted. Collaborate with other affiliate marketers and industry experts to exchange recommendations and insights on high-converting products.
By following these steps and conducting thorough research, you can identify and select high-converting products that are well-suited to your audience’s needs and preferences. Remember to prioritize quality, relevance, and alignment with your niche when choosing affiliate products, and continuously monitor and optimize your campaigns for optimal results.
**Build Trust with Your Audience**
Building trust with your audience is essential for long-term success in affiliate marketing. Trust forms the foundation of your relationship with your audience and directly influences their willingness to engage with your content and recommendations.

Share success stories from satisfied customers who have benefited from using the products you recommend. Social proof reinforces the credibility and reliability of your recommendations and helps alleviate any doubts or skepticism among your audience.
6. Disclose Affiliate Relationships: Be upfront and transparent about your affiliate relationships with your audience. Disclose your participation in affiliate programs and any potential incentives or commissions you may receive from recommending products. Honesty and transparency about your affiliate partnerships build trust and integrity with your audience and enhance your credibility as a trusted advisor.
7. Maintain Consistency and Reliability: Consistently deliver on your promises and commitments to your audience. Maintain a consistent publishing schedule for your content and ensure that your content is reliable, accurate, and up-to-date. Build a reputation for reliability and dependability by consistently delivering value and meeting your audience’s expectations.
8. Protect Your Audience’s Privacy: Respect your audience’s privacy and data security by implementing robust privacy policies and data protection measures.

Demonstrating a willingness to listen and adapt based on feedback shows that you value your audience’s input and strengthens your relationship with them.
By implementing these strategies consistently and authentically, you can build trust with your audience and establish yourself as a reliable and trustworthy affiliate marketer. Building trust takes time and effort, but the rewards of a loyal and engaged audience are well worth the investment.
**Create Compelling Content**
Creating compelling content is key to engaging your audience and driving affiliate conversions. Compelling content not only captivates your audience’s attention but also educates, entertains, and inspires them to take action. Here are some strategies to help you create compelling content for your affiliate marketing efforts:
1. Understand Your Audience: Start by understanding your audience’s needs, interests, and preferences. Conduct audience research to identify their pain points, challenges, and aspirations. Tailor your content to address their specific needs and provide valuable solutions that resonate with them.
2. Choose Engaging Formats: Experiment with different content formats to keep your audience engaged and interested. Consider using a mix of blog posts, videos, podcasts, infographics, case studies, and social media updates to cater to different preferences and learning styles. Use visually appealing images, graphics, and multimedia elements to enhance the readability and visual appeal of your content.
3. Tell Compelling Stories: Incorporate storytelling into your content to make it more relatable and memorable. Share personal anecdotes, experiences, and insights that illustrate the benefits and value of the affiliate products you’re promoting. Use storytelling techniques such as vivid imagery, emotional appeal, and narrative structure to captivate your audience’s attention and evoke an emotional response.
4. Provide Valuable Information: Offer informative and actionable insights that help your audience solve their problems or achieve their goals. Provide in-depth analysis, research findings, expert opinions, and practical tips that add value to your audience’s lives. Position yourself as a trusted source of information and expertise within your niche.

Create content that offers solutions to common problems, answers frequently asked questions or addresses specific pain points that your audience is struggling with. Position affiliate products as valuable tools or resources that can help alleviate their pain points and improve their lives.
6. Highlight Benefits and Features: Showcase the benefits and features of the affiliate products you’re promoting in your content. Communicate how the products solve your audience’s problems, meet their needs, or fulfill their desires. Highlight unique selling points, key features, and value propositions that differentiate the products from competitors and persuade your audience to take action.
7. Include Reviews and Testimonials: Incorporate product reviews, testimonials, and user feedback into your content to provide social proof and validate the effectiveness of the affiliate products. Share real-life experiences and success stories from satisfied customers who have benefited from using the products you recommend. Use quotes, ratings, and testimonials to reinforce the credibility and reliability of your recommendations.
8. Create Compelling Calls-to-Action (CTAs): Communicate the desired action you want your audience to take after consuming your content. Create compelling calls-to-action (CTAs) that encourage them to click on your affiliate links, make a purchase, sign up for a free trial, or take any other desired action. Use persuasive language, urgency, and incentives to motivate your audience to act immediately.
9. Optimize for SEO: Optimize your content for search engines to improve its visibility and reach. Conduct keyword research to identify relevant topics and keywords that your audience is searching for. Incorporate targeted keywords naturally into your content, headings, meta tags, and URLs to improve your search engine rankings and attract organic traffic.
10. Measure and Analyze Performance: Track the performance of your content using analytics tools to assess its effectiveness and impact on your affiliate conversions.

Remember to stay authentic, transparent, and focused on providing value to your audience in all your content efforts.
**Optimize Your Affiliate Links
**Optimizing your affiliate links is crucial for maximizing conversions and increasing your affiliate marketing revenue. By making your links more visually appealing, easier to manage, and strategically placed within your content, you can enhance the effectiveness of your affiliate marketing efforts. Here are some tips for optimizing your affiliate links:
1. Use Link Shortening Tools: Long, complex affiliate links can appear intimidating and may deter users from clicking on them. Use link-shortening tools like Bitly or TinyURL to create shorter, cleaner links that are easier to share and remember. Shortened links also allow you to track clicks and performance more effectively.
2. Customize Your Affiliate Links: Customize your affiliate links to make them more branded and trustworthy. Many affiliate programs allow you to create custom aliases or subdomains for your affiliate links, which can enhance their credibility and make them appear more professional. For example, instead of using a generic affiliate link, you could create a custom link like “yourwebsite.com/recommends/productname”.
3. Use Descriptive Anchor Text: Instead of using generic anchor text like “click here” or “learn more”, use descriptive anchor text that indicates what the user can expect when they click on the link. For example, if you’re promoting a product review, use anchor text like “read our in-depth review” or “check out this product”.
4. Incorporate Affiliate Links Naturally: Integrate your affiliate links seamlessly within your content to avoid appearing overly promotional. Instead of inserting affiliate links indiscriminately, strategically place them within relevant contexts, such as product reviews, comparison articles, or resource guides. Ensure that the placement feels natural and adds value to the user experience.
5. Use Visual Call-to-Actions (CTAs): Incorporate visual elements such as buttons or banners to make your affiliate links more noticeable and compelling. Design eye-catching CTAs that encourage users to click on your affiliate links and take action. Experiment with different colors, shapes, and sizes to optimize your CTAs for maximum visibility and click-through rates.
6. Disclose Affiliate Relationships: Be transparent with your audience about your affiliate partnerships and disclose your participation in affiliate programs whenever you promote affiliate products. Communicate that the links you’re sharing are affiliate links and that you may earn a commission if users purchase them. Transparency builds trust with your audience and enhances the credibility of your recommendations.
7. Optimize Link Placement: Experiment with different placement strategies to determine the most effective positions for your affiliate links within your content. Consider placing affiliate links strategically at the beginning, middle, or end of your content, as well as within prominent sections such as headings, bullet points, or call-out boxes. Test different placements to identify which ones yield the highest conversion rates.
8. Track and Analyze Performance: Monitor the performance of your affiliate links using analytics tools provided by affiliate networks or third-party tracking platforms. Track metrics such as click-through rates, conversion rates, and revenue generated from affiliate sales. Analyze the data to identify which links and placement strategies are driving the most conversions and optimize your approach accordingly.
9. Update and Refresh Links Regularly: Keep your affiliate links up-to-date and relevant by regularly reviewing and refreshing them as needed. Update outdated links, expired promotions, or discontinued products to ensure that users are directed to the most current and relevant offers. Refreshing your links also helps maintain user trust and prevents broken or irrelevant links from harming your credibility.
10. Comply with FTC Guidelines: Familiarize yourself with the Federal Trade Commission (FTC) guidelines for affiliate marketing and ensure that you comply with their disclosure requirements. Disclose your affiliate relationships and any potential incentives or commissions you may receive from promoting affiliate products. Use clear and conspicuous disclosure statements that are easily understandable to your audience.
By implementing these optimization strategies, you can make your affiliate links more effective, user-friendly, and conducive to driving conversions.

**Harness the Power of SEO**
Harnessing the power of SEO (Search Engine Optimization) is essential for driving organic traffic to your affiliate marketing content and maximizing your earning potential. By optimizing your content for search engines, you can improve its visibility, attract more targeted traffic, and increase your affiliate conversions. Here are some effective strategies for leveraging SEO in your affiliate marketing efforts:
1. Keyword Research: Conduct thorough keyword research to identify relevant search terms and phrases that your target audience is using to find information related to your niche and affiliate products. Use keyword research tools like Google Keyword Planner, SEMrush, or Ahrefs to discover high-volume keywords, long-tail keywords, and related search queries that you can incorporate into your content.
2. On-Page Optimization: Optimize your content for relevant keywords and search intent to improve its visibility in search engine results pages (SERPs). Incorporate target keywords naturally into your titles, headings, meta descriptions, and body content, while ensuring that the content remains engaging and valuable to your audience. Use descriptive and compelling titles and meta descriptions to entice users to click on your search listings.
3. Create High-Quality Content: Focus on creating high-quality, informative, and valuable content that addresses the needs, interests, and questions of your target audience. Publish in-depth articles, tutorials, guides, product reviews, and other forms of content that provide actionable insights, solutions, and recommendations. Aim to become a trusted resource and authority in your niche by consistently delivering valuable content that resonates with your audience.
4. Optimize for User Experience: Prioritize user experience (UX) by ensuring that your website is fast, mobile-friendly, and easy to navigate. Optimize your site structure, internal linking, and navigation menus to make it easy for users and search engines to find and access your content. Create clear and intuitive navigation paths that guide users to relevant pages and encourage them to explore further.
5. Optimize Images and Multimedia: Optimize your images and multimedia content for search engines by using descriptive filenames, alt text, and captions that include relevant keywords. Compress images to reduce file size and improve page load times, which can positively impact your site’s SEO performance. Use multimedia content strategically to enhance the visual appeal and engagement of your affiliate marketing content.
6. Build Quality Backlinks: Earn high-quality backlinks from authoritative websites and relevant sources within your niche to improve your site’s authority and credibility in the eyes of search engines. Focus on building natural and organic backlinks through content promotion, outreach, guest blogging, and partnerships with influencers and industry experts. Avoid spammy or manipulative link-building tactics that could result in penalties from search engines.
7. Optimize for Local SEO (if applicable): If you target a local audience or promote affiliate products with local relevance, optimize your content for local SEO to improve visibility in local search results. Create location-specific content, optimize your Google My Business listing, and solicit reviews from satisfied customers to enhance your local search presence and attract more targeted traffic.
8. Monitor and Analyze Performance: Use SEO analytics tools like Google Analytics, Google Search Console, and third-party SEO platforms to monitor your site’s performance, track keyword rankings, and identify areas for improvement. Analyze key metrics such as organic traffic, click-through rates, bounce rates, and conversion rates to assess the effectiveness of your SEO efforts and refine your strategy accordingly.
9. Stay Updated on SEO Trends: Stay informed about the latest SEO trends, algorithm updates, and best practices to stay ahead of the curve and maintain your competitive edge. Follow reputable SEO blogs, attend webinars, and participate in industry forums to stay updated on the latest developments in the world of search engine optimization. Adapt your SEO strategy accordingly to capitalize on emerging opportunities and mitigate potential risks.
10. Be Patient and Persistent: SEO is a long-term strategy that requires patience, persistence, and ongoing optimization efforts. It takes time to see significant results from your SEO initiatives, so stay committed to your strategy and continue to refine and improve your approach over time. Focus on providing value to your audience, building relationships with your readers, and creating high-quality content that resonates with both users and search engines.
By implementing these SEO strategies and best practices, you can effectively optimize your affiliate marketing content for search engines, attract more targeted traffic, and increase your affiliate conversions over time. Remember to prioritize user experience, relevance, and value in your SEO efforts to deliver the best possible experience for your audience and maximize your earning potential as an affiliate marketer.
**Diversify Your Income Streams**
Diversifying your income streams is a smart strategy for reducing risk, increasing stability, and maximizing your earning potential as an affiliate marketer. Relying solely on one affiliate program or product can leave you vulnerable to fluctuations in demand, changes in commission rates, or other unforeseen challenges. By diversifying your income streams, you can spread your risk and tap into multiple revenue sources within your niche. Here are some effective ways to diversify your income streams as an affiliate marketer:
1. Join Multiple Affiliate Programs: Partner with multiple affiliate programs and networks within your niche to expand your earning opportunities. Research and identify reputable affiliate programs that offer a diverse range of products, services, and commission structures. Join affiliate networks like ShareASale, CJ Affiliate, or Amazon Associates to access a wide selection of affiliate programs across different industries and verticals.
2. Promote a Variety of Products: Instead of focusing exclusively on one product or brand, diversify your product offerings by promoting a variety of products within your niche. Look for complementary products, alternative solutions, or related accessories that appeal to your audience’s interests and preferences. By offering a diverse range of products, you can cater to different needs and preferences and capture a larger share of the market.
3. Explore Different Affiliate Revenue Models: Experiment with different affiliate revenue models to diversify your income streams and optimize your earning potential. In addition to traditional affiliate commissions, consider promoting affiliate programs that offer recurring commissions, tiered commission structures, or performance-based incentives. Explore opportunities for lead generation, pay-per-click (PPC) advertising, or affiliate referrals to supplement your affiliate earnings.
4. Monetize Your Content with Ads: Supplement your affiliate earnings by monetizing your content with display ads, native ads, or sponsored content. Join ad networks like Google AdSense, Media.net, or Ezoic to display relevant ads on your website or blog. Incorporate ad placements strategically within your content to generate additional revenue without compromising the user experience.
5. Create and Sell Digital Products: Leverage your expertise and knowledge to create and sell your digital products, such as eBooks, online courses, software tools, or membership programs. Develop high-quality digital products that provide value to your audience and address their specific needs or pain points. Use your affiliate marketing channels to promote and sell your digital products to your existing audience and expand your revenue streams.
6. Offer Consulting or Coaching Services: Monetize your expertise and experience by offering consulting, coaching, or freelance services within your niche. Provide personalized guidance, advice, or support to individuals or businesses seeking help with specific challenges or objectives. Use your affiliate marketing platform to promote your consulting services and attract potential clients from your audience.
7. Explore Sponsorship and Brand Partnerships: Collaborate with brands, companies, or influencers within your niche to secure sponsorship deals or brand partnerships. Negotiate sponsored content, product placements, or brand endorsements that align with your audience’s interests and add value to your content. Seek out brands that share your values and vision to build mutually beneficial partnerships that enhance your credibility and reach.
8. Create Passive Income Streams: Invest time and resources in creating passive income streams that generate revenue with minimal ongoing effort or maintenance. Explore opportunities for affiliate marketing automation, recurring revenue models, or passive income strategies such as affiliate niche sites, automated email marketing campaigns, or digital asset sales. Build scalable income streams that continue to generate passive income over time, allowing you to earn money while focusing on other aspects of your business.
9. Diversify Across Platforms and Channels: Expand your presence across multiple platforms and channels to reach a broader audience and diversify your income streams. In addition to your website or blog, explore opportunities to leverage social media platforms, video-sharing sites, podcasting platforms, or email marketing channels to promote affiliate products and engage with your audience. Adapt your content and promotional strategies to suit each platform’s unique audience and features.
10. Track and Analyze Your Income Streams: Monitor the performance of your income streams and analyze key metrics such as revenue, conversion rates, and ROI (Return on Investment) regularly. Identify which income streams are performing well and which ones may need optimization or adjustment. Use data-driven insights to refine your strategies, prioritize high-performing channels, and allocate resources effectively to maximize your overall earnings.
By diversifying your income streams and exploring multiple revenue opportunities within your niche, you can create a more resilient and sustainable affiliate marketing business. Experiment with different strategies, adapt to changing market conditions and continuously seek out new opportunities for growth and expansion. Diversification not only reduces risk but also opens up new avenues for innovation, creativity, and success as an affiliate marketer.

Use segmentation to tailor your strategies and messaging to specific audience segments and improve targeting.
8. A/B Test and Experiment: Conduct A/B tests and experiments to evaluate different strategies, tactics, and variations of your affiliate content. Test different headlines, calls-to-action, landing page designs, or promotional offers to determine which elements drive the best results. Use split testing tools and statistical analysis to measure the impact of changes and optimize your campaigns based on data-driven insights.
9. Monitor Trends and Seasonality: Stay informed about industry trends, seasonal fluctuations, and market dynamics that may impact your affiliate marketing performance. Monitor seasonal trends, holidays, or special events that could affect consumer behavior and purchasing patterns. Adjust your strategies and promotional efforts accordingly to capitalize on opportunities and mitigate challenges.
10. Iterate and Optimize: Continuously iterate and optimize your affiliate marketing strategies based on performance data and insights. Identify areas for improvement, experiment with new approaches, and refine your tactics to maximize your results over time.

By staying persistent and patient, you can identify what works best for your audience and fine-tune your approach for better results.

5. Learning and Growth: Affiliate marketing is a dynamic and ever-evolving field, and there’s always something new to learn and explore. It’s important to stay curious, open-minded, and willing to learn from both successes and failures. By staying persistent and patient, you can embrace the learning process, adapt to changes, and continue to grow and evolve as an affiliate marketer over time.
6. Celebrating Small Wins: While it’s important to stay focused on your long-term goals, it’s also crucial to celebrate small wins along the way. Recognize and acknowledge your achievements, no matter how small they may seem. Celebrating milestones, accomplishments, and progress can help boost morale, motivation, and confidence, reinforcing your commitment to your affiliate marketing journey.
7. Maintaining Motivation: Affiliate marketing requires self-discipline, motivation, and self-motivation. There may be times when you feel discouraged or tempted to give up, especially if you’re not seeing immediate results.

Remember why you started your affiliate marketing journey in the first place, and stay committed to your vision and aspirations.

title: Elixir入門 08: モジュールと関数
published: true
description: Elixir公式サイトの許諾を得て「Modules and functions」の解説にもとづき、加筆補正を加えてElixirのモジュールと関数についてご説明します。
tags: #elixir, #webdev, #tutorial, #programming
---
本稿はElixir公式サイトの許諾を得て「[Modules and functions](https://elixir-lang.org/getting-started/modules-and-functions.html)」の解説にもとづき、加筆補正を加えてElixirのモジュールと関数についてご説明します。
Elixirはモジュールに関数をまとめてグループ化します。たとえば、[`String.length/1`](https://hexdocs.pm/elixir/String.html#length/1)はUTF-8のUnicode文字数を調べる`String`モジュールの関数です。
```elixir
iex> String.length("hello")
5
```
モジュールをつくるには、[`defmodule/2`マクロ](https://hexdocs.pm/elixir/Kernel.html#defmodule/2)を用います。さらに、その中に関数を定めるのが[`def/2`マクロ](https://hexdocs.pm/elixir/Kernel.html#def/2)です。モジュールと関数はつぎの構文でつくられます。
```elixir
iex> defmodule Math do
...> def sum(a, b) do
...> a + b
...> end
...> end
iex> Math.sum(1, 2)
3
```
モジュールや関数を定めてコードが長くなると、`iex`モードではテストしにくくなるでしょう。コンパイルやスクリプトモードを使えば、ファイルに書いたプログラムが試せます。
# コンパイル
Elixirのプログラムを書いたファイルには拡張子`.ex`をつけます。たとえば、つぎのコードを`math.ex`というファイル名で保存したとしましょう。
```elixir
defmodule Math do
def sum(a, b) do
a + b
end
end
```
コンパイルするには、コマンドラインツールから`elixirc ファイル名`を打ち込んでください。コンパイルされたバイトコードのファイルが`Elixir.モジュール名.beam`という名前でつくられるはずです(図001)。
```terminal
$ elixirc math.ex
```
#### 図001■モジュールのバイトコードがつくられた
そのあと`iex`を起ち上げれば、そのディレクトリにあるバイトコードファイル(`.beam`)が読み込まれ、モジュールも使えるようになるのです。
```elixir
iex> Math.sum(1, 2)
3
```
実際の開発には[`mix`](https://hexdocs.pm/mix/Mix.html)というビルドツールを使うことになるでしょう。プロジェクトの作成、コンパイル、テスト、依存関係の管理などがこのツールの役割です。Elixirのプロジェクトでは、通常つぎの3つのディレクトリにそれぞれのファイルを納めて開発します。
- ebin - コンパイルされたバイトコードファイル
- lib - Elixirコードファイル(拡張子`.ex`)
- test - テストファイル(拡張子`.exs`)
# スクリプトモード
スクリプトモードではバイトコードファイルはつくることなく、プログラムを実行します。ファイルにつける拡張子は`.exs`です。中身は`.ex`ファイルと同じで、コンパイルしたモジュールがメモリに読み込まれて実行されます。バイトコードをディスクに書き出さないことを示すため、異なる拡張子が使われるのです。
```elixir
defmodule Math do
def sum(a, b) do
a + b
end
end
IO.puts Math.sum(1, 2)
```
スクリプトモードで実行するには、コマンドラインツールからコマンド`elixir ファイル名`入力します。プログラムから結果を出力するには。`IO.puts/2`関数をお使いください。
```terminal
$ elixir math.exs
3
```
モジュールを読み込んだうえで`iex`で使いたいときは、コマンドラインツールから`iex ファイル名`のコマンドで起ち上げてください。
```terminal
$ iex math.exs
```
```elixir
iex> Math.sum(3, 4)
7
```
# 名前つき関数
モジュールに`def/2`で定めた関数は、他のモジュールから呼び出せます。外から参照させないプライベートな関数を定義するために用いるのが[`defp/2`](https://hexdocs.pm/elixir/Kernel.html#defp/2)です。なお、ハッシュ記号`#`のあとの記述はコメントとして無視されます。
```elixir
defmodule Math do
def sum(a, b) do
do_sum(a, b)
end
defp do_sum(a, b) do
a + b
end
end
IO.puts Math.sum(1, 2) #=> 3
IO.puts Math.do_sum(1, 2) #=> ** (UndefinedFunctionError)
```
```terminal
$ elixir math.exs
3
** (UndefinedFunctionError) function Math.do_sum/2 is undefined or private
Math.do_sum(1, 2)
math.exs:12: (file)
(elixir) lib/code.ex:677: Code.require_file/2
```
関数の定めには、ガードと複数の句が加えられます。複数の句は、Elixirが上から順に試し、マッチした句を実行するのです。引数がいずれにもマッチしなければ、エラーになります。なお、関数名の最後に疑問符`?`を添えるのは、論理値が返される場合のElixirにおける[命名規則](https://hexdocs.pm/elixir/master/naming-conventions.html#trailing-question-mark-foo)です。
```elixir
defmodule Math do
def zero?(0) do
true
end
def zero?(x) when is_integer(x) do
false
end
end
IO.puts Math.zero?(0) #=> true
IO.puts Math.zero?(1) #=> false
IO.puts Math.zero?([1]) #=> ** (FunctionClauseError)
IO.puts Math.zero?(0.0) #=> ** (FunctionClauseError)
```
`if/2`と同じく、名前つき関数には`do/end`ブロックのほか、`do:`を用いたキーワードリストの構文が使えます(「[Elixir入門 05: 条件 - case/cond/if](https://dev.to/gumi/elixir-05----casecondif-60o)」「do/endブロック」および「[Elixir入門 07: キーワードリストとマップ](https://dev.to/gumi/elixir-07--39hi)」「キーワードリスト」参照)。前掲コードは、つぎのようにも書けるのです。
```elixir
defmodule Math do
def zero?(0), do: true
def zero?(x) when is_integer(x), do: false
end
```
ただし、`do:`の構文は1行で済む場合に用い、複数行にわたるときは`do/end`ブロックで書いた方がよいでしょう。
# 関数のキャプチャ
前掲の`Math.zero?/1`が定められたモジュール(ファイル名math.exsとします)を例に、`iex`で関数のキャプチャを試してみましょう。
```terminal
$ iex math.exs
```
```elixir
iex> Math.zero?(0)
true
```
Elixirは無名関数と名前つき関数を区別します。無名関数の納められた変数から関数を呼び出すには、変数のあとにドット`.`を添えなければなりません(「[Elixir入門 02: 型の基本](https://dev.to/gumi/elixir-02--30n1)」「無名関数」参照)。
キャプチャ演算子[`&/1`](https://hexdocs.pm/elixir/Kernel.SpecialForms.html#&/1)を用いると、名前つき関数を変数に入れて、無名関数と同じように呼び出せます。代入する関数には、アリティを添えてください。なお、[`is_function/1`](https://hexdocs.pm/elixir/Kernel.html#is_function/1)は引数が関数かどうかを確かめます。
```elixir
iex> fun = &Math.zero?/1
&Math.zero?/1
iex> is_function(fun)
true
iex> fun.(0)
true
```
組み込み済みの関数も、`&/1`演算子で変数に納めて呼び出せます。
```elixir
iex> is_fun = &(is_function/1)
&:erlang.is_function/1
iex> is_fun.(fun)
true
iex> (&is_number/1).(1.0)
true
```
`&/1`演算子を用いると無名関数も簡略に書けます。たとえば、つぎの無名関数を定めたいとしましょう。
```elixir
square = fn(x) -> x * x end
```
`&/1`演算子を使えば、つぎのように短く書けます。さらに、他の無名関数とも組み合わせられるのです。
```elixir
iex> square = &(&1 * &1)
#Function<6.99386804/1 in :erl_eval.expr/5>
iex> square.(2)
4
iex> square_sum = &(square.(&1) + square.(&2))
#Function<12.99386804/2 in :erl_eval.expr/5>
iex> square_sum.(3, 4)
25
```
モジュールの関数もキャプチャすると、モジュールなしで呼び出せるようになります。[`List.flatten/2`](https://hexdocs.pm/elixir/List.html#flatten/2https://hexdocs.pm/elixir/List.html#flatten/2)は引数のふたつのリストをつなげたうえで、入れ子を平坦化する関数です。引数ふたつを与えていますので、キャプチャにアリティは添えません。
```elixir
iex> flatten = &List.flatten(&1, &2)
&List.flatten/2
iex> flatten.([1, [[2], 3]], [4, 5])
[1, 2, 3, 4, 5]
```
モジュールの関数を利用した新たな関数もつくれます。なお、[`math`](https://elixir-lang.org/getting-started/erlang-libraries.html#the-math-module)はErlangのモジュールで、[`:math.sqrt/1`](http://erlang.org/doc/man/math.html#sqrt-1)は平方根を求める関数です。
```elixir
iex> hypot = &:math.sqrt(square_sum.(&1, &2))
#Function<12.99386804/2 in :erl_eval.expr/5>
iex> hypot.(3, 4)
5.0
```
上の関数はつぎのようにも定められます。
```elixir
iex> hypot = &:math.sqrt(&1 * &1 + &2 * &2)
#Function<12.99386804/2 in :erl_eval.expr/5>
iex> hypot.(3, 4)
5.0
```
# デフォルト引数
名前つき関数の引数には、あとに`\\`に続けてデフォルト値が定められます。
```elixir
defmodule DefaultTest do
def dowork(x \\ "hello") do
x
end
end
```
```elixir
iex> DefaultTest.dowork()
"hello"
iex> DefaultTest.dowork("hi")
"hi"
iex> DefaultTest.dowork(1)
1
```
デフォルト値にはどのような式でも与えられます。ただし、値が評価されるのは、関数を定義したときではありません。関数が呼び出されてデフォルト値が用いられるたびに、その値は評価されるのです。
```elixir
defmodule Concat do
def join(a, b, sep \\ " ") do
a <> sep <> b
end
end
```
```elixir
iex(2)> Concat.join("hello", "world")
"hello world"
iex(3)> Concat.join("hello", "world", ", ")
"hello, world"
```
複数の句をもつ関数にも、デフォルト値は使えます。ただし、アリティを同じくする句には、関数本体のないヘッダで定めなければなりません。コンパイルエラーのメッセージにはその旨が示されます。
```elixir
defmodule Greeter do
def hello(name \\ nil, language \\ "em") when is_nil(name) do
phrase(language) <> "world"
end
def hello(name, language \\ "en") do
phrase(language) <> name
end
defp phrase("en"), do: "hello, "
defp phrase("ja"), do: "こんにちは"
end
```
```terminal
** (CompileError) greeter.ex:6: definitions with multiple clauses and default values requi
re a header. Instead of:
def foo(:first_clause, b \\ :default) do ... end
def foo(:second_clause, b) do ... end
one should write:
def foo(a, b \\ :default)
def foo(:first_clause, b) do ... end
def foo(:second_clause, b) do ... end
def hello/2 has multiple clauses and defines defaults in one or more clauses
greeter.ex:6: (module)
(stdlib) erl_eval.erl:670: :erl_eval.do_apply/6
```
句が複数ある関数のデフォルト値は、ヘッダの引数に`\\`で与えてください。
```elixir
defmodule Greeter do
def hello(name \\ nil, language \\ "en")
def hello(name, language) when is_nil(name) do
phrase(language) <> "world"
end
def hello(name, language) do
phrase(language) <> name
end
defp phrase("en"), do: "hello, "
defp phrase("ja"), do: "こんにちは"
end
```
```elixir
iex> Greeter.hello()
"hello, world"
iex> Greeter.hello("alice")
"hello, alice"
iex> Greeter.hello("太郎", "ja")
"こんにちは太郎"
```
デフォルト値を与えるときは、関数の定義が重複しないよう気をつけてください。
```elixir
defmodule Concat do
def join(a, b) do
IO.puts "#=> join/2"
a <> b
end
def join(a, b, sep \\ " ") do
IO.puts "#=> join/3"
a <> sep <> b
end
end
```
上の関数をコンパイルすると、つぎのような警告が示されます。ふたつの引数を渡すとつねにアリティ2の関数が呼び出され、アリティ3のデフォルト値が使われることはないからです。
```terminal
warning: this clause cannot match because a previous clause at line 2 always matches
```
エラーではありませんので、コンパイルはでき、関数も呼び出せます。アリティ3の関数は3つの引数を渡さないかぎり呼び出されません。引数がふたつのときどういう結果を得たいのか考え直すべきでしょう。
```elixir
iex(1)> Concat.join("hello", "world")
#=> join/2
"helloworld"
iex(2)> Concat.join("hello", "world", ", ")
#=> join/3
"hello, world"
```
つぎのコードは、関数のデフォルト値とパターンマッチングを使った例です。[`Enum.join/2`](https://hexdocs.pm/elixir/Enum.html#join/2)は、リスト([`Enumerable`](https://hexdocs.pm/elixir/Enumerable.html))要素の間に第2引数の文字列を挟んで、バイナリ(文字列)につなげる関数です。
```elixir
defmodule Greeter do
def hello(names, language \\ "en")
def hello(names, language) when is_list(names) do
hello(Enum.join(names, ", "), language)
end
def hello(name, language) when is_binary(name) do
phrase(language) <> name
end
defp phrase("en"), do: "hello, "
defp phrase("ja"), do: "こんにちは"
end
```
```elixir
iex> Greeter.hello("alice")
"hello, alice"
iex> Greeter.hello(["alice", "carroll"])
"hello, alice, carroll"
iex> Greeter.hello(["桃太郎", "金太郎", "浦島太郎"], "ja")
"こんにちは桃太郎, 金太郎, 浦島太郎"
```
なお、上のコードの最初の関数は、パイプ演算子[`|>`](https://hexdocs.pm/elixir/Kernel.html#%7C%3E/2)を用いると、つぎのようにすっきりと書き替えられます。`|>`は左オペランドの値を、右オペランドの関数に第1引数として渡す演算子です。
```elixir
def hello(names, language) when is_list(names) do
# hello(Enum.join(names, ", "), language)
names
|> Enum.join(", ")
|> hello(language)
end
```

Enabling Windows Authentication seems like an easy deal, you only need to configure some info that your organization must provide you:
- **Fully qualified domain name.** It's often a URL like `microsoft.com`
- **Domain organization unit.** It will look like this: `OU=AWS_ACCOUNT_NAME,OU=A_NUMBER,DC=YOUR_ORGANIZATION`
- **Authorization secret ARN.** The Active Directory credentials (user and password).
- **Domain organization unit.** Some range of IPs.
- **Secondary DNS.** Another range of IPs.
However, the tricky part is to configure the secret since it's unclear. The first part is to **Store a new secret**.
Then, you need to choose, **Other type of secret**:
You need to store the following keys:
- `CUSTOMER_MANAGED_ACTIVE_DIRECTORY_USERNAME`: Your AD user.
- `CUSTOMER_MANAGED_ACTIVE_DIRECTORY_PASSWORD`: Your AD password.
After you have created the secret, you must make some changes to the Resource permissions section.
Search for the **Principal** section and secure the RDS info is there:
```json
"Principal" : {
"Service" : "rds.amazonaws.com"
}
```
After this is done, check if the **Condition** section exists and if not, modify it like this:
```json
"Condition" : {
"StringEquals" : {
"aws:sourceAccount" : "YOUR_AWS_ACCOUNT_ID"
},
"ArnLike" : {
"aws:sourceArn" : "arn:aws:rds:YOUR_REGION:YOUR_AWS_ACCOUNT_ID:db:*"
}
}
```
Where:
- The `aws:sourceAccount` is your AWS account ID.
- The `aws:sourceArn` is the one that enables the RDS that can have access to your secret. In this example, I gave access to all DBs inside our AWS account by using the `*`.
This should be enough to enable you to access your Self Managed Active Directory.

1,791,252 | How to Detect and Fix Circular Dependencies in Typescript | When coding in TypeScript or Angular and embracing types, sometimes we don't pay attention to... | 0 | 2024-03-15T10:39:09 | https://www.danywalls.com/how-to-detect-and-fix-circular-dependencies-in-typescript | typescript, javascript, frontend | When coding in TypeScript or Angular and embracing types, sometimes we don't pay attention to "Circular dependencies". We create types and try to use them everywhere to match with the existing structure, and if we're not careful, it's so easy to create a circular reference and dependency loop that can be problematic in our code.
Today, I want to show how easy it is to create circular dependencies and how to fix them.
## **Scenario**
We are building an app that shows buttons based on a theme. The buttons must have a theme and a label, and the user can set a config or use a default.
We are using TypeScript. To ensure you have TypeScript installed, if not, run the command:
```typescript
npm i -g typescript
```
After that, create a new directory from the terminal and generate a default TypeScript config with `tsc --init`:
```bash
mkdir circular-references
cd circular-references
tsc --init
```
## **Create The Types**
First, we create `theme.ts` with the properties related to colors and fontFormat.
```typescript
export type Theme = {
color: string;
fontFormat: string;
};
```
Next, because we want to keep our code split, we create the file `button.ts` for the buttons. The button type has two properties: `label` as a string and `theme` of type `Theme`.
> **Remember to import the Theme**
```typescript
import { Theme } from "./theme";
export type ButtonConfig = {
label: string;
theme: Theme;
};
```
This code looks fine without any circular dependency, perfect, but now it's time to continue with our project.
## **Using The Theme**
We want to provide two types of themes: Dark and Light, and a default configuration for the users, defining a list of buttons based on the theme. Open again `theme.ts` and create the themes.
```typescript
export const DarkTheme: Theme = {
color: 'black',
fontFormat: 'italic'
};
export const LightTheme: Theme = {
color: 'white',
fontFormat: 'bold'
};
```
Next, for the `defaultConfig`, set to use a theme with a list of buttons based on the theme. Let's import the ButtonConfig and assign the theme.
```typescript
import { ButtonConfig } from "./button";
export const defaultThemeConfig: ThemeConfig = {
buttons: [
{
theme: DarkTheme,
label: 'Accept'
},
{
theme: DarkTheme,
label: 'Cancel'
}
],
type: 'dark'
};
```
Everything seems to be working as expected.
* Split the types for buttons and themes into separate files.
* Created light and dark themes.
* Set up a default configuration.
It looks like our code is functioning correctly. Let's go ahead and use it.
## **Build Dummy App**
We create an example app with the function to show buttons based on the config. If there's no config, then use the `defaultThemeConfig`.
Create the `main.ts` file and import the `defaultThemeConfig`. Create the app with a function `showButtons`, inside check if config doesn't exist use the `defaultThemeConfig`.
The code looks like this:
```typescript
import { defaultThemeConfig } from "./theme-config";
const app = {
config: undefined,
showButtons() {
const config = this.config ?? defaultThemeConfig;
console.log(config);
}
};
app.showButtons();
```
In the terminal, compile `main.ts` using `tsc` and run with `node`.
```bash
$circular-references>tsc main.ts
$circular-references>node main.js
{
buttons: [
{ theme: [Object], label: 'Accept' },
{ theme: [Object], label: 'Cancel' }
],
type: 'dark'
}
```
Yeah! Our app works as expected, but wait a minute. Did you see `theme.ts` requires `button.ts` and `button.ts` uses `theme.ts`?
## **Circular Reference 😖**
We created a circular reference. Why? Because the buttons require the theme and vice versa. Why did this happen?
Because we created the Theme and ThemeConfig in the same file, while also having a dependency on ButtonConfig.
The key to the circular dependency was:
1. `theme.ts` defined `Theme` and wanted to use `ButtonConfig` (which required `Theme`).
2. `button.ts` defined `ButtonConfig` that depended on `Theme` from `theme.ts`.
In my case, it's easy to see, but if you have an already large project, the best way to see your circular dependency is with the package [madge](https://www.npmjs.com/package/madge), it reports all files with circular dependencies.
> Madge **is amazing tool to** generating a visual graph of project dependencies, finding circular dependencies and giving other useful information [\[read more\]](https://www.npmjs.com/package/madge)
In our case, run the command `npx madge -c --extensions ts ./`.
```bash
npx madge -c --extensions ts ./
```
Ok I have the issue how to fix ?
## Fixing Circular Dependency
To fix the circular reference issue between `theme.ts` and `button.ts`, we must to create a new file to break the relations to ensure that the dependencies between these files are unidirectional, extracting the common dependencies into a separate file. In our case we can move all related to theme config `ThemeConfig` and default configuration in a new file `theme-config.ts`.
Create a specific file for `ThemeConfig`, help us to keeps the theme-related configurations separate from the theme and button definitions.
Let's to refactor
### **The Theme**
The theme.ts only needs to export types contain the definitions for `Theme` and the theme instances like `DarkTheme` and `LightTheme`.
```typescript
export type Theme = {
color: string;
fontFormat: string;
};
export const DarkTheme: Theme = {
color: 'black',
fontFormat: 'italic',
};
export const LightTheme: Theme = {
color: 'white',
fontFormat: 'bold',
};
```
### **Update the** `button.ts` File
Now, modify the `button.ts` file to type, which relies on `Theme` from `theme.ts`.
```typescript
import { Theme } from "./theme";
export type ButtonConfig = {
label: string;
theme: Theme;
};
```
### **Create Theme-config.ts**
Create `theme-config.ts` its contain the `ThemeConfig` and the default configuration for the theme, utilizing `ButtonConfig` from `button.ts` and indirectly, `Theme` from `theme.ts`.
```typescript
import { ButtonConfig } from "./button";
import { DarkTheme } from "./theme";
export type ThemeConfig = {
type: 'dark' | 'light';
buttons: Array<ButtonConfig>;
};
export const defaultThemeConfig: ThemeConfig = {
buttons: [
{
theme: DarkTheme,
label: 'Accept'
},
{
theme: DarkTheme,
label: 'Cancel'
}
],
type: 'dark'
};
```
Run the widget again and voila! 🎉
## What We did ?
Yes, we fixed the circular dependency by making a small structural change:
* `theme.ts` is independent and defines the base `Theme` type and objects `DarkTheme` and `LightTheme`.
* `button.ts` depends on `theme.ts` for the `Theme` type.
* `theme-config.ts` depends on both `button.ts` for the `ButtonConfig` type and `theme.ts` for the theme objects, bringing them together into a configuration object.
This we eliminate the circular dependency by organizing the code into a more linear dependency : `theme.ts` ➔ `button.ts` ➔ `theme-config.ts`. Each file has a clear responsibility, and the dependency direction is from the definition of the theme and button configuration.
I hope this helps you think about and fix your circular dependencies, or even avoid them altogether in the future 🚀

- Constructor functions are a fundamental aspect of Object-Oriented Programming (OOP) in JavaScript.
- They allow us to create objects with predefined properties and methods. In this blog post, we'll explore the concept of constructor functions and how they can be used to create objects in JavaScript.
- Simply, Constructor function as **template**. This template is used for **creating an object**.
### ⚡ Understanding Constructor Functions:
- Constructor functions are special functions in JavaScript used to create and initialize objects.
- They serve as blueprints for creating multiple instances of objects with shared properties and methods.
### ⚡ Exploring the Code:
Let's break down the code snippet you provided:
```javascript
function Person(_name, _age) {
this.name = _name;
this.age = _age;
this.greet = function () {
console.log(`Hi, Welcome ${this.name}`)
}
}
```
**Function Declaration:**
- We declare a function named `Person` , which serves as our constructor function.
- It takes two parameters: `_name` and `_age` , representing the name and age of a person.
**Initializing Properties:**
- Inside the constructor function, we use the `this` keyword to create properties `name` and `age` for each instance of the `Person` object.
- The values of these properties are set based on the arguments passed to the constructor function.
**Adding a Method:**
We define a method named `greet` within the constructor function. This method allows each `Person` object to greet with a personalized message.
## ⚡ Instance Creation
```javascript
const person1 = new Person('Manikandan', 25);
```
**Creating an Instance:**
We create a new instance of the `Person` object using the `new` keyword, passing 'Manikandan' as the name and 25 as the age.
**Logging the Object:**
We log the `person1` object to the console, which displays the properties and methods associated with it.
```javascript
console.log(person1) // Person Person { name: 'Manikandan', age: 25, greet: [Function (anonymous)] }
```
**Invoking the Method:**
We invoke the `greet` method on the `person1` object, which logs a personalized greeting message to the console.
```javascript
person1.greet(); // Hi, Welcome Manikandan
```
### ⚡ Conclusion:
Constructor functions are essential in JavaScript for creating objects with predefined properties and methods. They provide a convenient way to structure and organize code in an Object-Oriented manner. By understanding constructor functions, you'll be better equipped to leverage the power of OOP in your JavaScript projects. Happy coding..!🧑🏻💻

It... | 0 | 2024-03-15T11:27:09 | https://dev.to/yellowcoder/dereferencing-in-rust-2f9f | rust, dereference, webassembly, pointer | Dereferencing refers to the process of accessing the value that a pointer or reference points to. It is done using the dereference operator *
```rust
//@yellowcoder
//example #1
fn main(){
let x = 5;
let y = &x; // y is a reference to x
println!("{}", x); // Prints: 5
println!("{}", y); // Prints: 5 (automatically dereferenced)
println!("{}", *y); // Prints: 5 (explicitly dereferenced)
}
```
In the example above, x is the actual value (5), while y is a reference that points to the memory location where x is stored. When we try to print y directly, we get the memory address. To get the actual value 5, we need to dereference y using *y.
Dereferencing is necessary because Rust's ownership and borrowing rules are designed to ensure memory safety. References are just "views" into the actual data, and they don't own or control the data's lifetime. By requiring explicit dereferencing, Rust ensures that you are aware of when you're accessing the actual data through a reference, rather than the reference itself.
This explicit dereferencing helps catch potential bugs and promotes more readable and safer code, as it clearly distinguishes between working with references and working with the actual values they point to.
In summary, we need to dereference references in Rust to access the actual values they point to, as references themselves are just pointers to memory locations, not the values stored at those locations.
! Have a look on the below example 🧐
```rust
//@yellowcoder
//example #2
fn example(z: &mut i32) {
*z = 0; // dereferencing to 0
println!("value of z -> {}", *z); // Prints: 'value of z -> 0'
}
fn main(){
println!(&mut 4);
}
```

## Introduction
As a Software Developer who spends more time on the Backend, every now and then I try to do some things on the frontend occassionally. I wanted to explore [Pinia](https://pinia.vuejs.org/) and experience some of its features. In this post, I will share how I persisted data using Pinia and localStorage.
## The App
To create the Vue 3 app, we run the command below and follow the prompt. Be sure to add Pinia for state management.
`npm create vue@latest`
You can run the commands to install dependencies and start the app.
`cd project-name`
`npm install`
`npm run dev`
Open the App with an editor(I use Vscode).
Create a file named authStore.js inside the src/stores folder. Add this code to the file.
```js
import { defineStore } from "pinia";
import { ref, computed } from "vue";
export const useAuthStore = defineStore("auth", () => {
const user = ref(null);
const getUser = computed(() => user.value);
const setUser = (newUser) => {
user.value = newUser;
};
return {
user,
setUser,
getUser,
};
});
```
We can now use the store values in our views. I had to clean up the default codes in the view files.
**src/App.vue**
```js
<script setup>
import { RouterLink, RouterView } from 'vue-router'
import HelloWorld from './components/HelloWorld.vue'
</script>
<template>
<header>
<nav>
<RouterLink to="/">Home</RouterLink>
<RouterLink to="/about">About</RouterLink>
</nav>
</header>
<RouterView />
</template>
<style scoped>
</style>
```
**src/Home.vue**
```js
<script setup>
import { ref } from 'vue';
import { useAuthStore } from '@/stores/authStore';
const authStore = useAuthStore();
const name = ref(null);
const login = () => {
authStore.setUser(name.value);
};
</script>
<template>
<main>
<h1>Home</h1>
<p v-if="authStore.user !== null">Welcome, {{ authStore.getUser }}</p>
<div>
<h3>Enter your name</h3>
<form @submit.prevent="login">
<input type="text" v-model="name">
<button type="submit">Login</button>
</form>
</div>
</main>
</template>
```
**src/About.vue**
```js
<script setup>
import { useAuthStore } from '@/stores/authStore';
const authStore = useAuthStore();
</script>
<template>
<div class="about">
<h1>This is an about page</h1>
<p v-if="authStore.user !== null">Welcome, {{ authStore.getUser }}</p>
</div>
</template>
<style>
</style>
```
In the App.vue, I removed all the unnecessary codes. In the home and about, I mimicked a login and the user value was saved to the store. So, in a real login system we can have data from API and save it to the store and use across pages.
## The Issue
If you notice, when the page is refreshed, the user value in the store resets to null. This is because Pinia stores are not persisted across refreshes.
## The fix
There are different ways to fix this particular issue. I will use localstorage to solve this in the store. We have to make a few changes.
Update the login method in Home.vue. This stores the value in the localstorage.
```js
const login = () => {
authStore.setUser(name.value);
localStorage.setItem('app_user', name.value);
};
```
Update the authStore to load value from localstorage if the value exists.
```js
import { defineStore } from "pinia";
import { ref, computed } from "vue";
export const useAuthStore = defineStore("auth", () => {
const user = ref(null);
if (localStorage.getItem("app_user")) {
user.value = localStorage.getItem("app_user");
}
const getUser = computed(() => user.value);
const setUser = (name) => {
user.value = name;
};
return {
user,
setUser,
getUser,
};
});
```
With these changes, even with page reload, the data persists! Be sure to drop comments, questions or suggestions.

Image source: [Lazy documentation](https://www.lazyvim.org/)
### Getting Started with LazyVim <a name="getting-started"></a>
Alright, let's dive into the setup process. Here's what you'll need:
**Neovim:** Make sure you have _Neovim_ installed on your system. You can check the official website for installation instructions: https://neovim.io/
**Git:** We'll be using Git to clone the _LazyVim_ starter pack. If you don't have _Git_, you can download it from https://git-scm.com/downloads
#### Step 1: Back Up Your Existing Neovim Files (Just in Case) <a name="step-1"></a>
Before we start fresh, it's always a good idea to back up any existing _Neovim_ configurations you might have. This way, you can easily revert if needed. You can use commands like:
```bash
# required
mv ~/.config/nvim{,.bak}
# optional but recommended
mv ~/.local/share/nvim{,.bak}
mv ~/.local/state/nvim{,.bak}
mv ~/.cache/nvim{,.bak}
```
These commands will move your existing _Neovim_ configuration to a backup folder named `nvim.bak`.
You get a bare vim.
#### Step 2: Install Optional Tools (Makes things smoother) <a name="step-2"></a>
_LazyVim_ works great on its own, but there are a couple of optional tools that can enhance your experience:
**ripgrep:** A super-fast file searcher. You can install it using your system's package manager (e.g., `brew install ripgrep` on macOS).
**fd:** Another blazing-fast file finder. Installation instructions can be found here: https://github.com/sharkdp/fd
#### Step 3: Clone the LazyVim Starter Pack <a name="step-3"></a>
Now for the fun part! Open your terminal and navigate to your desired installation directory. We'll use the `git clone ` command to download the _LazyVim_ starter pack:
```bash
git clone https://github.com/LazyVim/starter ~/.config/nvim
```
This command clones the _LazyVim_ starter pack into your _Neovim_ configuration directory (`~/.config/nvim`).
#### Step 4: Remove the .git Folder (Keeps things clean) <a name="step-4"></a>
The _LazyVim_ starter pack comes with a `.git` folder for version control purposes. Since we won't be actively contributing to the _LazyVim_ codebase, we can remove this folder for a cleaner setup:
```bash
rm -rf ~/.config/nvim/.git
```
#### Step 5: Launch Neovim and Witness the Magic! <a name="step-5"></a>
Now you're ready to experience the power of _LazyVim_! Open your terminal and launch _Neovim_ using the command:
```bash
nvim
```
_Neovim_ will launch, and you'll see a message indicating that plugins are being installed automatically. This might take a few moments depending on your internet speed.
Explore Your New Playground!
In the next article, we'll dive into personalizing your _LazyVim_ setup with custom `themes`, `keymaps`, and more. Stay tuned!

1,791,985 | Laravel 11: Publish Broadcasting Channels Route File | In this quick guide, I'll demonstrate how to publish a broadcasting channel route file in the Laravel... | 0 | 2024-03-16T05:22:09 | https://dev.to/techsolutionstuff/laravel-11-publish-broadcasting-channels-route-file-4ooc | laravel, laravel11, route, brodcasting | In this quick guide, I'll demonstrate how to publish a broadcasting channel route file in the Laravel 11 framework.
With the impending release of Laravel 11, users can anticipate a host of new features and enhancements.
Notably, Laravel 11 boasts a more streamlined application structure and introduces features like per-second rate limiting and health routine.
By default, Laravel 11 doesn't display the broadcasting channels route file, and you're unable to define broadcasting channel routes within it.
However, if you wish to define such routes, you'll need to publish the broadcasting channels route file using the command provided below.
This command not only publishes the channels.php file
So, let's see how to publish the broadcasting channel route file in laravel 11.
Run the following command to publish the Broadcasting Channels route file.
```
php artisan install:broadcasting
```
The install:broadcasting command will create a routes/channels.php file where you may register your application's broadcast authorization routes and callbacks.
routes/broadcasting.php
```
<?php
use Illuminate\Support\Facades\Broadcast;
Broadcast::channel('App.Models.User.{id}', function ($user, $id) {
return (int) $user->id === (int) $id;
});
```
When running the install:broadcasting command, you will be prompted to install Laravel Reverb.
you may also install Reverb manually using the Composer package manager. Since Reverb is currently in beta, you will need to explicitly install the beta release.
```
composer require laravel/reverb:@beta
```
Once the package is installed, you may run Reverb's installation command to publish the configuration, add Reverb's required environment variables, and enable event broadcasting in your application.
```
php artisan reverb:install
```

## Resume building and curating
Keep your resume up-to-date. Curate your resume by keeping it focused. Make a resume for each job application to best utilize keywords used in the role you want.
## Portfolio projects
Always have a coding project that showcases your current skills for the public to view. Most software engineers are bound by NDA and legal restrictions. If you are one of those definitely work on a portfolio piece.
## Networking
Keep your professional networks alive. Take time to check-in with folks. Share your good, by being positive. Your network will help you gain trust with potential employers. They also can give you insight on the hiring process or manager.
## Write blog post and create content
Blogging and creating videos are excellent methods to establish yourself as an authority in your field. By sharing your knowledge and experiences, you invite the opportunity to learn from the feedback of others
## Contribute to Open Source Software (OSS)
Engage with GitHub and become involved. As a software engineer, teamwork is essential, and GitHub is a fantastic platform for learning how to collaborate asynchronously with others. Begin with technologies you're familiar with, or if you're not using any, focus on those you're passionate about. Dive into the repository "Issues" and "Pull Requests" to see where you can contribute. If you're unsure where to start, consider enhancing documentation—whether through editing, correcting, or adding text. Another valuable contribution is adding unit tests. Every project benefits from additional support, so don't hesitate to ask, "How can I help?"
## Ask Questions?
Ask questions of people working in roles you want to have. Let the professionals talk and take time to listen.
- "How do you like your current role?"
- "What do you like about it?"
- "Do you have any tips for me?"
## Help others code
Answer questions and dedicate your time to assist others learning to code. The amount of personal and professional growth achieved by helping answer other developers' questions is remarkable.
## Find a mentor, or become a mentor
Mentoring can be challenging, as it involves offering guidance and support without expecting compensation. Seeking a mentor requires finding someone willing to volunteer their time to guide you on your path. As a mentor, it means being accessible to answer questions from those less experienced and sharing your knowledge with individuals eager to learn and grow. | trewaters |

pubDate: "March 15, 2024"

> **tl;dr** - A method for creating localized error messages with [tRPC](https://trpc.io).
> - Using a custom error with localization keys
> - Associating errors with form fields
> - Full [example](https://github.com/gcascio/trpc-i18n-errors)
<br />
There are many cases where you want to present a server error to the user, i.e., when a user tries to sign up with an email that is already in use. In these cases, it's important to present the error message in the user's language. This is a guide on how to do that with tRPC.
<br />
We start with a project that was bootstrapped with [create-t3-app](https://create.t3.gg/). For internationalization we use [next-intl](https://github.com/amannn/next-intl) and set it up as described in the [getting started guide](https://next-intl-docs.vercel.app/docs/getting-started/app-router). With this initial project setup we can jump into implementing localized error messages.
<br />
<br />
## Getting started
<br />
When localizing messages of any kind we need to decide where we want the localization to happen, i.e., the mapping from localization keys to the actual messages. An approach often used is to apply the localization at the last moment, namely, just before the user is presented with it on the client. This way we push the translation to the edge of the application and we can work with localization keys everywhere else.
<br />
Essentially, this means we want to send localization keys as part of a tRPC error and then map them to the translations on the client. To achieve this we extend the `TRPCError` class and add a `i18nKey` property to it:
```ts
import { TRPCError } from '@trpc/server';
import type { useTranslations } from 'next-intl';
type I18nNamespaceKeys = Exclude<Parameters<typeof useTranslations>[0], undefined>;
export type I18nKeys<T extends I18nNamespaceKeys = I18nNamespaceKeys>
= Parameters<ReturnType<typeof useTranslations<T>>>[0];
export class I18nTRPCError extends TRPCError {
public readonly i18nKey: I18nKeys;
constructor(opts: {
i18nKey: I18nKeys;
} & ConstructorParameters<typeof TRPCError>[0]) {
const { i18nKey, ...rest } = opts;
super(rest);
this.i18nKey = i18nKey;
}
}
```
Additionally, we take advantage of next-intl's types to type the `i18nKey` property. We can then use this new class to throw localized errors:
```ts
throw new I18nTRPCError({
code: 'BAD_REQUEST',
message: 'Post with this name already exists',
i18nKey: 'postAlreadyExistsError',
});
```
and access the `i18nKey` property in the client:
```ts
const t = useTranslations('posts');
const createPost = api.post.create.useMutation({
onError: (error) => {
const message = t(error.data?.i18nKey);
// Instead of logging it we would present it to the user for example with a toast
console.log(message);
},
});
```
<br />
<br />
## Associating errors with form fields
<br />
We can go a step further though. When validating form fields on the server we would like to associate the error with the form field which caused it, so we can present the user with more context on what caused the error. At this point you might have already realized that we can achieve this by adding another field to our custom error, namely, `formField` which will reference the name of the affected form field:
```ts
export class I18nTRPCError extends TRPCError {
public readonly i18nKey: I18nKeys;
public readonly formField?: string;
constructor(opts: {
i18nKey: I18nKeys;
formField?: string
} & ConstructorParameters<typeof TRPCError>[0]) {
const { i18nKey, formField, ...rest } = opts;
super(rest);
this.i18nKey = i18nKey;
this.formField = formField;
}
}
```
we set this field as optional since not every error will be associated with a form field. On the client side we can then use the `formField` to decide how to present the error. For example, we can use it to set the error message on the exact form field that caused the error:
```ts
const t = useTranslations('posts');
const createPost = api.post.create.useMutation({
onError: (error) => {
const message = t(error.data?.i18nKey);
if (!error.data?.formField) {
// Instead of logging it we would present it to the user for example with a toast
console.log(message);

1,792,600 | Routing with React Router | Navigating through pages in a React application is made possible using a library called React Router... | 0 | 2024-03-17T01:30:19 | https://dev.to/paulstar200/routing-with-react-router-4kj7 | react, javascript, routing | Navigating through pages in a React application is made possible using a library called React Router Dom.
We will walk through Routing with an example.
First we will use vite to quickly spin up a React project.
`npm create vite@latest`
Enter your project name and select all options you would prefer when prompted.
Here is my preferred configuration.
Install all dependencies using `npm install`
To install react-router-dom, run the following command
`npm i react-router-dom`
Run the app using `npm run dev`
Create a components folder under the `src` directory and then create two components: `Home` and `About` inside the components folder.
**ROUTING**
For routing, create a folder called router under src and within it, create `index.tsx`.
Our folder structure should now look like this:
Now inside our router file, we will create routes for our Home and About pages as follows.
```
import { createBrowserRouter } from "react-router-dom";
import Home from "../components/Home";
import About from "../components/About";
const router = createBrowserRouter([
{
path: "/",
element: <Home/>,
},
{
path: "/about",
element: <About />,
},
]);
export default router;
```
Note that we imported `createBrowserRouter` from react-router-dom. This is the recommended router for all React Router web projects. It uses the DOM History API to update the URL and manage the history stack.
We then go to our `App.tsx` file and replace everything within it as follows.
App.tsx
```
import "./App.css";
import { Outlet } from "react-router-dom";
function App() {
return (
<>
<Outlet />
</>
);
}
export default App;
```
You'll notice we imported `Outlet` from react-router-dom and added it in our return statement. An Outlet should be used in parent route elements to render their child route elements. This allows nested UI to show up when child routes are rendered. If the parent route matched exactly, it will render a child index route or nothing if there is no index route. In this case, our parent route element is the `App.tsx` file and the child routes are `Home.tsx` and `About.tsx`
Lastly, we will update our `main.tsx` file with RouteProvider from react-router-dom
We import our router first and pass it into `RouterProvider`. All data router objects are passed to this component to render your app and enable the rest of the data APIs.
main.tsx
```
import React from "react";
import ReactDOM from "react-dom/client";
import "./index.css";
import router from "./router/index.tsx";
import { RouterProvider } from "react-router-dom";
ReactDOM.createRoot(document.getElementById("root")!).render(
<React.StrictMode>
<RouterProvider router={router} />
</React.StrictMode>
);
```
Now if we go to the browser you can navigate routes between our two pages!
Home Page
About Page
That's all you need! Or is it?
Suppose you tried accessing a route like `/home`, what do you think will happen? Let's see.
Yikes! We had not specified a route for `/home`. We only put two routes: `/` and `/about`. To fix this, we can add a route to handle non-existent routes.
Firstly, create a component that will render whenever a user accesses a non existent route.
```
import React from "react";
const Error = () => {
return <div>This is the error page</div>;
};
export default Error;
```
Next, we go to our router file, import the Error component we just created, and add a path to handle non-existent routes as follows:
```
{
path: "*",
element: <Error />,
},
```
And this is our result if we go to a non-existent route:
This tutorial is just a tip of the iceberg when it comes to React Router. I would encourage you to explore more and see what React router has to offer you. The full documentation of react-router can be found at: https://reactrouter.com/en/main

Among the multitude of functionalities, the role of email infrastructure stands out as integral. And it touches upon critical aspects of your email flows, including:
- Synchronization
- Analytics
- Templates
- Campaigns
- Security
- Compliance
- Document generation and validation
To explain it a bit simpler, Salesforce is about the seamless integration of email communication with customer data. In turn, you get to have personalized interactions with your clients. Also, you get to make informed business decisions based on those interactions.
All things considered, it’s safe to say that the existence and usability of these apps also helped with widespread Salesforce adoption.
Speculations aside, we delve into some of the most effective Salesforce applications for various components of your email infrastructure. So, let’s dive right in.
## Best Salesforce Apps: A Quick Overview
When evaluating Salesforce apps related to email infrastructure, it’s essential to keep in mind that the “best” app depends heavily on specific business needs and workflows.
For example, sales cloud users looking for ways to improve their sales process might require different apps than service cloud users. But, to guide this exploration, we’ve considered the universal factors that contribute to an array of business workflows related to email infrastructure.
Firstly, the **features offered by the app play a significant role**. We looked for apps that provide a robust set of capabilities, giving users **the flexibility to manage various aspects of email infrastructure** efficiently.
Secondly, we took **15+ years of our experience in building and maintaining email infrastructures** and distilled it into editorial chunks to give you a first-hand assessment of the given apps.
We aim to gauge the following:
- Real-world applications
- Reliability
- How the apps match up to their advertised promises.
Also, we’ve checked how these apps have aided businesses in solving their unique challenges.
Finally, compatibility with Salesforce is a non-negotiable criterion.
The chosen apps integrate seamlessly with Salesforce.com, ensuring users can conveniently leverage their capabilities within the CRM environment.
However, some of the listed apps are paid-only and geared more towards advanced Salesforce org users, which with be explicitly stated within the review. Some also offer free options and, as there’s no free Salesforce, it’s a good way to test things out before you commit to a plan.
Having accounted for all of the above, we’ve selected and categorized a range of Salesforce apps that excel in handling specific email infrastructure tasks. Read on for more details.
## Salesforce Apps for Email Synchronization
Efficient email synchronization is pivotal in streamlining your Salesforce operations, ensuring all relevant communication is captured and accessible within the platform. With these, you take the functionality of the Lightning app to the next level.
Anyway, here’s one of the top apps in this arena.
### Cirrus Insight
[Cirrus Insight](https://www.cirrusinsight.com/) acts as a bridge between the Salesforce environment and your inbox, reducing the tedious task of constantly flipping between email and Salesforce.
### Key features
The automatic sync of emails and attachments from your inbox to Salesforce truly stands out. It enables you to efficiently store and access every relevant piece of communication within Salesforce.
Calendar Sync is another notable feature. It ensures all your meetings, calls, and events (like a webinar, for example) are synced between your email and Salesforce, providing frictionless scheduling and improved time management.
Cirrus Insight also offers contextual Salesforce insights right in the inbox. With this feature, you can view and update Salesforce records without leaving your email, making for a more efficient workflow.
### Our two cents
Indeed, the automatic sync feature is a significant productivity booster. We appreciate the ease of accessing Salesforce data right from the inbox. This will consistently shave off minutes from your workflow, leading to improved time efficiency.
Now, we have to stress that there’s a bit of a learning curve, as this app is for intermediate to advanced users of the Marketing Cloud, and other Salesforce editions. The good news is that the app is well-documented, so you shouldn’t struggle to figure out the ropes.
### Ebsta
[Ebsta](https://www.ebsta.com/) is another noteworthy app for email synchronization, designed to empower Salesforce users with greater control over their email management. Its core strength lies in the ability to sync and surface relevant Salesforce data directly in your inbox.
### Key features
Comprehensive email synchronization is Ebsta’s strong suit. The app ensures that all your email conversations, events, and contacts are automatically synced with Salesforce. It also features a real-time activity tracking capability, enabling users to see who is engaging with their emails right away.
Another standout feature is Ebsta’s cross-platform compatibility. Whether you’re using Gmail, Outlook, or another email client, Ebsta allows you to access crucial Salesforce data without leaving your inbox.
Finally, Ebsta’s calendar synchronization provides the easy scheduling of meetings and events, which are then automatically updated in Salesforce. So, there’s less chance you’ll miss an important interaction.
### Our two cents
Again, we like Ebsta’s robust synchronization features, which can notably improve your workflow. The integration with various email clients is seamless, and real-time activity tracking can be a game-changer, particularly for your sales team.
For instance, let’s imagine the interaction happens at an odd hour and your sales rep is out of the office. The rep could get a real-time notification on Salesforce Mobile, and act on it immediately.
Lastly, we observed less of a learning curve compared to Cirrus Insight. But this is a highly subjective parameter, so take it with a grain of salt.
## Salesforce Apps for Email Analytics
When it comes to email infrastructure within Salesforce, having insightful analytics is indispensable. It allows for data-driven decisions, ensuring your communication strategy is aligned with your audience’s needs. Let’s explore one of the leading apps for email analytics.
### Full Circle Insights
[Full Circle Insights](https://fullcircleinsights.com/) is an app designed to offer robust email analytics within the Salesforce CRM. It aims to bridge the gap between data and insights, making it easier to understand your email engagement.
### Key features
Full Circle Insights brings several key features to the table.
- **Response Management** – designed to provide a detailed understanding of your email performance, tracking engagement metrics such as opens, clicks, and conversions directly within Salesforce.
- **Campaign Influence** – lets you see the direct and indirect influence of your emails on sales opportunities, providing insights into the effectiveness of your email strategy.
- **Funnel Metrics** – gives a comprehensive view of your sales funnel, helping you understand how emails contribute at each stage of the customer journey.
### Our two cents
Full Circle Insights provides a depth of analytics that could satisfy even the most demanding users. The Response Management feature, in particular, offers great granularity and accuracy. We also appreciate the sales funnel insights, which can be quite a helper in optimizing your email strategy.
So, to no surprise, this Salesforce integration requires a certain level of expertise to fully exploit its capabilities. But once mastered, its potential to transform email strategy and inform business processes is undeniable.
On that note, we should stress that this is an enterprise-level app, which is reflected in its pricing.
## Salesforce Apps for Feedback and User Experience Management
In the Salesforce landscape, receiving and managing customer feedback is crucial. It can inform and drive improvements to product features, services, and user experience.
Here are two apps designed to simplify feedback collection and enhance user experience.
### Zonka Feedback
[Zonka Feedback](https://www.zonkafeedback.com/) is a comprehensive tool for capturing and analyzing feedback within Salesforce Lightning. Its primary objective is to help businesses measure customer sentiment and improve their overall experience.
### Key features
Zonka offers real-time feedback capture, allowing you to respond quickly to customer needs. It supports various feedback channels, including email, SMS, and on-site feedback, giving your customers the flexibility to interact through their preferred channels.
With its rich analytics, you can easily understand customer sentiment, identify trends, and track improvement over time. The app give you the option to set up instant notifications for specific feedback. In turn, you get to act immediately, when required.
### Our two cents
The most useful Zonka features are multi-channel feedback collection and in-depth analytics. Plus, real-time feedback capture can have a significant impact on quick problem resolution, particularly for customer success and customer relationship teams.
If we’re really nitpicky (which we aren’t), Zonka might benefit from more customization options. But overall, it’s among the best feedback apps, suitable for small businesses and enterprises alike.
### Survicate
[Survicate](https://survicate.com/?utm_source=google&utm_medium=cpc&utm_campaign=survicate&utm_adgroup=brand&utm_term=survicateec&camp_id=354108535&adgroup_id=21487992055&ad_id=549742337202&hsa_tgt=kwd-342540695034&hsa_grp=21487992055&hsa_src=g&hsa_net=adwords&hsa_mt=e&hsa_ver=3&hsa_ad=549742337202&hsa_acc=6519365081&hsa_kw=survicate&hsa_cam=354108535&gclid=Cj0KCQiAgK2qBhCHARIsAGACuznN9ENe_dMWfRMKFqvsPTQGlfUvq47PhjXVbUbyzV7se2B0QRBaT58aAmgWEALw_wcB&gad_source=1) is a survey tool that allows you to collect continuous customer feedback via email, web, in-product, and mobile apps. It offers over 300 ready-to-use survey templates, including NPS, CSAT, and CES, making survey creation a breeze.
### Key features
Integrating Salesforce and Survicate is a one-click, code-free process – there’s no need for complex technical configurations.
With Survicate, you can seamlessly embed surveys directly into [Salesforce emails](https://mailtrap.io/blog/salesforce-mass-email/), enhancing your feedback collection process and enriching customer interactions. Users can conveniently share valuable insights without having to visit external platforms.
As data between the two tools is synced in real time, survey responses are immediately accessible in Salesforce, which makes it easy to take prompt actions based on customer feedback.
### Our two cents
We like that Survicate captures every response, even if a user didn’t fill in every field, meaning you won’t lose any data.
The transfer of contact attributes between Salesforce and Survicate is very easy indeed, and it helps you quickly filter survey insights and trigger workflows based on responses.
### Jotform
[Jotform Salesforce Forms](https://www.jotform.com/salesforce-forms/) is a robust solution for creating and managing forms within the Salesforce ecosystem. It’s designed to streamline the sales process by automating form data synchronization with your Salesforce account.
### Key Features
The platform offers an intuitive [form builder](https://www.zonkafeedback.com/blog/best-form-builder-software-tools), enabling the creation of custom forms that seamlessly integrate with Salesforce. It’s great that you can start with ready-made templates and customize them fast. Plus, the forms are optimized for iOS and Android users.
Also, the feature that allows sharing prefilled forms with customers is a standout because it simplifies the form-filling process a lot. And the automatic data sync with Salesforce CRM ensures that the data flow into your database is effortless.
Additionally, Jotform offers an electronic signature collection through Jotform Sign. It can be a godsend for sales teams looking to expedite their deal closures.
### Our Two Cents
The ease of form creation and customization is a highlight indeed. And the same goes for automatic sync and prefilled forms. The reporting and analytics are adequate, but there’s room for more advanced analytical tools. Nonetheless, Jotform’s balance of simplicity and functionality makes it a great tool for Salesforce users.
## Salesforce Apps for Email Security and Compliance
In the realm of Salesforce and the Appexchange apps, security and compliance are paramount. Keeping sensitive data safe and adhering to industry regulations can make a significant difference to your business’s credibility and trustworthiness. Here are the key apps that excel in these aspects.
### OwnBackup
[OwnBackup](https://www.ownbackup.com/) is a comprehensive solution designed to protect your Salesforce data, including emails. It offers a suite of tools to ensure your email data remains secure and compliant with industry standards.
### Key features
At the core of OwnBackup is a robust backup and restore functionality. It automatically backs up data from the CRM platform, including emails, attachments, and metadata. In the event of data loss, you can restore custom objects or entire orgs without too much hassle.
The app also offers a comprehensive suite of compliance tools. With features like audit trails and encrypted backups, OwnBackup helps you meet compliance standards such as GDPR and HIPAA.
Finally, its Sandbox Seeding feature is a standout, letting you easily create and manage test data environments without compromising security or compliance. If you’re a SaaS, this feature will allow for more stable workflows, helping you remove preventable errors from production.
### Our two cents
OwnBackup has backup-and-restore capabilities that can further streamline project management and completion. Also, its comprehensive compliance features can give you the peace of mind that both your static and in-transit data remain intact.
Admittedly, the user interface could be a bit more intuitive. However, for such a robust security and compliance solution, it’s not a deal breaker by any means.
###Cloud Compliance
[Cloud Compliance](https://cloudcompliance.app/) is a purpose-built app for Salesforce that provides an efficient solution for data privacy and compliance management.
Basically, the app makes it simpler for you to meet complex regulatory requirements while ensuring the integrity of your email data.
### Key features
There’s a comprehensive suite of tools that help manage personal data in Salesforce. And here’s a quick scoop of what you might find most useful.
- Data Discovery and Classification – allows you to locate and categorize personal data, aiding in GDPR and CCPA compliance.
- Data Retention and Deletion – enables you to set and automate data retention policies, ensuring unnecessary data doesn’t linger and contribute to compliance risks.
- Privacy Portal – allows data subjects to access and manage their data rights requests, further enhancing your compliance stance.
### Our two cents
Cloud Compliance is a Salesforce native app, so there’s almost no learning curve, and you get the benefit of native integration. In plain English, if you understand Salesforce, you shouldn’t struggle with Cloud Compliance at all.
To that, the efficiency and completeness of the compliance features are hard to rival.
For instance, Data Discovery and Classification, along with automated Data Retention, are great aids in meeting GDPR and CCPA requirements.
## The Role of Mailtrap in the Salesforce Ecosystem
In the Salesforce ecosystem, various apps bolster different aspects of email management.
[Mailtrap](https://mailtrap.io/), however, holds a distinct and multifaceted role in this arena.
It’s an **email delivery platform for businesses and individuals** that offers robust features to **test, send, and control emails in one place**.
## Overview of Mailtrap
As indicated, Mailtrap’s functionality extends beyond the bounds of testing, but first things first.
[Mailtrap Testing](https://mailtrap.io/email-sandbox/) **adds an email sandbox to your Salesforce toolbox** to help developers test and debug emails without the risk of email templates from staging ever reaching your recipients.
How?
It goes like this:
1. We give you a fake SMTP server.
2. The server captures outgoing test emails.
3. We analyze content for spam and validate HTML/CSS.
4. The developers view errors, debug, then proceed to send highly-deliverable emails
The sending part is, of course, covered by Mailtrap Email **Sending functionality via API or SMTP**. It’s designed for transactional and bulk emails. Plus, there are five SDKs to integrate Mailtrap with your app quicker.
- [NodeJS SDK](https://github.com/railsware/mailtrap-nodejs)
- [Ruby SDK](https://github.com/railsware/mailtrap-ruby)
- [PHP SDK](https://github.com/railsware/mailtrap-php)
- [Python SDK](https://github.com/railsware/mailtrap-python)
- [Elixir SDK](https://github.com/railsware/mailtrap-elixir)
On top of that, Mailtrap provides color-coded, user-friendly analytics, email templates, and webhooks.
[Try Mailtrap Now](https://mailtrap.io/register/signup?ref=header)
### How does it differ from the aforementioned apps?
While other Salesforce apps focus on aspects such as synchronization, analytics, feedback, user experience, and security, Mailtrap brings **a unique combination of pre-production email testing and robust email sending and analytics capabilities**.
Also, there’s a technical difference. Unlike other apps in this article, Mailtrap integrates with Salesforce via Salesforce’s Email Relay feature. If you want to learn more about this, check our “[How to Set up Salesforce Email Relay](https://mailtrap.io/blog/salesforce-email-relay/)” blog post.
**Note**: Soon, you’ll be able to integrate Mailtrap Email Testing to Lightning Experience via AppExchange.
### What added value does it bring to Salesforce users?
We’re at liberty to stress that Mailtrap carves out a special niche in the Salesforce ecosystem. The key highlight is its ability to catch emails from the staging environment and also manage email production operations with just-in-time delivery.
For Salesforce users, Mailtrap provides a unique blend of utility and control over their emails. As indicated, with Mailtrap email sandbox for testing, you can **prevent unintended emails from reaching customers** during the development phase.
Then, Mailtrap Email Sending allows you to send emails fast and reliably. It also offers comprehensive analytics, email templates, and [webhooks](https://help.mailtrap.io/article/102-webhooks). So you can have almost instant access to deliverability events and email data (assuming you use webhooks). And consequently, gain better control over your email infrastructure.
All this results in more effective communication with existing customers, higher user adoption, and better customer support; leading to improved customer experience.
And lastly, we’d need to point out that Mailtrap integrates with Salesforce using the Email Relays functionality, allowing for a seamless transition of data and operations between the two platforms.
### What trends to look for with Salesforce apps?
As the Salesforce ecosystem continues to adapt and expand, there are several trends worth keeping an eye on in relation to email infrastructure.
1. **Data management and security**
With the growing emphasis on data privacy and regulations, we can expect to see even more sophisticated features dedicated to email security and compliance. This includes more advanced encryption methodologies, AI-powered anomaly detection, and improved auditing capabilities.
For instance, Mailtrap is already using a state-of-the-art AI model for the following.
- Filter and block spammers and protect our IPs
- Run domain authentication and trustworthiness
2. **Integrations galore**
Integration is the key! Expect to see more Salesforce apps offering seamless integration with other platforms and tools. This trend is driven by the need for interconnected tools that provide users with like an all-in-one, streamlined workflow.
3. Y**our users/customers are front-center**
Undoubtedly, user experience will remain a primary focus. With an increasing demand for personalized customer experiences, email management tools will likely continue to evolve to allow for more personalized and [interactive email templates](https://mailtrap.io/blog/interactive-emails/) and designs.
**Bonus Tip**:
[Salesforce Labs](https://appexchange.salesforce.com/category/salesforce-labs-apps), which we haven’t covered in this article, also offers plenty of free apps and integrations, some of which are designed as mobile apps. For example, we like the [Trail Tracker](https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000EFpAtUAL) by Trailhead a lot, even though it’s not directly related to email infrastructure. But if you have a team that just migrated to Salesforce, it could really flatten the learning curve.
### Final Thoughts and Conclusion
When all’s said and done, Salesforce apps related to email infrastructure are integral components of an effective Salesforce strategy.
Whether it’s for email synchronization, analytics, user experience management, security, compliance, or whatever you need; these apps provide a measurable value by enhancing efficiency and ensuring the integrity of your email operations.
In this ever-evolving landscape, Mailtrap stands out with its unique combination of robust email testing and sending functionalities, making it an invaluable tool for any business using Salesforce.

Permissions determine who can read, write, and execute a file.
The permissions are represented by three groups: owner, group, and others. Each of these groups has three types of permissions: read (r), write (w), and execute (x).
To change permissions using `chmod`, you can use either symbolic mode or numeric mode. In numeric mode, permissions are represented by three octal digits:
1. The first digit represents the permissions for the owner.
2. The second digit represents the permissions for the group.
3. The third digit represents the permissions for others.
Each digit is a combination of the following values:
- 4 for read permission (r)
- 2 for write permission (w)
- 1 for execute permission (x)
You add these values together to assign permissions. For example:
- 7 = 4 (read) + 2 (write) + 1 (execute) = full permissions (rwx)
- 6 = 4 (read) + 2 (write) = read and write permissions (rw-)
- 5 = 4 (read) + 1 (execute) = read and execute permissions (r-x)
- 4 = 4 (read) = read-only permissions (r--)
- 0 = No permissions (--)
So, when you use `chmod` with numeric mode, you specify the desired permission using these digits. For example, to give read, write, and execute permissions to the owner, read and execute permissions to the group, and only execute permission to others, you would use:
```
chmod 751 filename
```
This would set the permissions as follows:
- Owner: rwx (7)
- Group: r-x (5)
- Others: --x (1)

Hoisting is one of those interesting behaviors of JavaScript that can sometimes lead to unexpected results, especially for those new to the language. In this article, we'll explore what hoisting is, how it works, and look at some examples to get a clearer picture.

<a name="Variable_Hoisting"></a>
##Variable Hoisting
Variable hoisting is a JavaScript mechanism where variable declarations are moved to the top of their containing scope before the code has been executed. This means that no matter where variables are declared, they are moved to the top of their scope by the JavaScript interpreter.
Importantly, only the declarations are hoisted, not the initializations. This distinction is crucial for understanding some of the puzzling behavior that can arise.
To illustrate how variable hoisting works, let's look at a few examples.
**Example 1: Basic Variable Hoisting**
```javascript
console.log(myVar); // Output: undefined
var myVar = 5;
```
In this example, you might expect a ReferenceError since `myVar` is printed before it's declared. However, due to hoisting, the JavaScript interpreter sees the code as follows:
```javascript
var myVar;
console.log(myVar); // Output: undefined
myVar = 5;
```
**Example 2: `let` and `const` Hoisting**
The introduction of `let` and `const` in ES6 has somewhat altered the landscape of hoisting. Unlike `var`, which is hoisted to the top of its scope, `let` and `const` are hoisted to the top of their block scope but are not initialized, leading to what is called a "Temporal Dead Zone" (TDZ).
```javascript
console.log(myLetVar); // ReferenceError: Cannot access 'myLetVar' before initialization
let myLetVar = 3;
```
In this scenario, `myLetVar` is hoisted, but trying to access it before declaration results in a ReferenceError.
**Example 3: Re-declaring Variables with `var`**
```javascript
var myVar = 1;
console.log(myVar); // Output: 1
var myVar = 2;
console.log(myVar); // Output: 2
```
In this example, despite `myVar ` being declared twice, JavaScript's hoisting mechanism processes and consolidates the declarations at the top of their scope. The reassignment of `myVar` to `2` happens after the initial assignment, leading to the final value of `2` being logged. Below is how the JavaScript engine interprets the code as if it's written like this:
```javascript
var myVar;
myVar = 1;
console.log(myVar);
myVar = 2;
console.log(myVar);
```
<a name="Function_Hoisting"></a>
## Function Hoisting
In JavaScript, functions are subject to hoisting much like variables are. However, how function hoisting works depends on how the function is declared.
**Example 4: Function Declaration Hoisting**
Function declarations are fully hoisted. This means that the entire body of the function, along with its declaration, is hoisted to the top of its scope. Here's how it works:
```javascript
console.log(myFunc()); // Output: "Some text!"
function myFunc() {
return "Some text!";
}
```
**Example 5: Function Expression Hoisting**
Function expressions behave differently. If a function is assigned to a variable, the variable declaration is hoisted but not the assignment. This distinction is crucial for understanding how different function declaration methods behave regarding hoisting.
Consider this example using a function expression with `var`:
```javascript
console.log(myFunc); // Output: undefined
console.log(myFunc()); // TypeError: myFunc is not a function
var myFunc = function() {
return "Some text!";
};
```
Here, the variable `myFunc ` is hoisted to the top of its scope, meaning it exists and is `undefined` when we try to log it or call it. This results in a TypeError when attempting to invoke `myFunc` as a function before the function expression is assigned to it.
For function expressions using `let` or `const`, an attempt to use them before declaration will lead to a ReferenceError because `let` and `const` declarations are in a TDZ as described earlier.
<a name="Class_Hoisting"></a>
## Class Hoisting
Classes in JavaScript exhibit the same hoisting behavior to variables declared with `let` and `const`. When you declare a class, its declaration is hoisted to the top of its enclosing scope, much like `let` and `const`. However, just as `let` and `const` declarations are not initialized until the JavaScript engine executes their declaration line, classes too are not initialized until the engine evaluates their declaration. This also results in a TDZ, meaning any attempts to access the class before its declaration will result in a `ReferenceError`. So, dealing with inheritance, static methods, and other object-oriented programming constructs, ensure that base classes are defined before derived classes try to extend them, respecting the TDZ.
<a name="Type_Alias"></a>
## Type Alias & Interface "Hoisting" in TypeScript
TypeScript's type aliases and interfaces are purely a design-time construct, meaning they are used by the TypeScript compiler for type checking and are erased when the TypeScript code is compiled to JavaScript. So, the concept of hoisting doesn’t really apply to type aliases or interfaces because they do not exist in the compiled output and, therefore, have no impact on the runtime behavior of the code.
For example:
```typescript
let myVar: MyType = { key: "value" };
type Animal = {
key: string;
};
```
In the code above, even though the `MyType ` type is used before its declaration, TypeScript does not throw an error. This is because, from the perspective of the TypeScript type checking system, all type declarations are considered to be known ahead of any value-space code execution or evaluation. This isn't hoisting in the traditional JavaScript sense, but rather a feature of TypeScript's static analysis that all type declarations are globally known to the compiler before any code execution.
<a name="Tricky_Tasks"></a>
## Tricky Tasks
**Task 1.**
```javascript
var myVar = 1;
var myFunc = function() {
console.log(myVar); // Output: ?
var myVar = 2;
console.log(myVar); // Output: ?
}
myFunc();
```
**Task 2.**
```javascript
function myFunc() {
return 1;
}
console.log(myFunc()); // Output: ?
function myFunc() {
return 2;
}
console.log(myFunc()); // Output: ?
```
**Task 3.**
```javascript
(function() {
try {
throw new Error();
} catch (x) {
var x = 1, y = 2;
console.log(x); // Output: ?
}
console.log(x); // Output: ?
console.log(y); // Output: ?
})();
```
<a name="Solutions"></a>
## Solutions
**Task 1.**
- When `myFunc` is invoked, JavaScript hoists the declaration of `myVar` to the top of the function scope. This means the code inside `myFunc` behaves as if it was written like this:
```javascript
var myVar = undefined;
console.log(myVar); // Output: undefined
myVar = 2;
console.log(myVar); // Output: 2
```
- Therefore, the first `console.log(myVar)` outputs `undefined` because the declaration (but not the initialization) of `myVar` is hoisted to the top of the function scope, overshadowing the `myVar` declared outside the function scope.
- After `myVar` is assigned the value of `2` within the function, the second `console.log(myVar)` outputs `2`.
**Task 2.**
- Both function declarations are hoisted to the top of their scope. However, the second declaration of `myFunc` overwrites the first. This is because in JavaScript, function declarations are hoisted above variable declarations and are processed before the code begins to run.
- Therefore, regardless of where the functions are declared, the version of `myFunc` that finally resides in memory after hoisting and interpretation is the one that returns `2`.
- Both `console.log(myFunc());` calls will output `2`, because that's the version of `myFunc` being used after hoisting and overwriting.
**Task 3.**
- In the `catch` block, variables `myVar1` and `myVar2` are declared. Since `var` declarations are function-scoped (not block-scoped like `let` or `const`), both `myVar1` and `myVar2` are hoisted to the top of their enclosing function.
- Therefore, `console.log(myVar1);` within the `catch` block outputs `1`.
- Outside the `catch` block but inside the self-invoking function, both `myVar1` and `myVar2` are accessible due to hoisting, and since they were assigned values in the `catch` block, their values are preserved outside of the catch block.
- `console.log(myVar1);` outside the `catch` block also outputs `1`.
- Similarly, `console.log(myVar2);` outputs `2`. | antonzo |

1,793,098 | My Arch Linux Experiment: Could It Be the Secret Weapon for Digital Asset Tax Work? | Hey everyone!

I'm Lance, the Baruch College accounting student who's always got one eye on the crypto world. Lately, I've been wrestling with the mind-bending world of digital asset taxation (fun, right?) and building some tools to make my life easier. But here's the thing – I've started tinkering with Arch Linux, and I'm wondering if it could be a game-changer for my work.
## Why I'm Tired of Bloat
Look, I love tech, but sometimes it feels like every operating system comes with a side of software I never asked for. Tax research databases, spreadsheets, Python environments – that's my jam, not pre-installed games and photo editors. Arch's "build your own adventure" approach is strangely refreshing. It might mean a steeper learning curve, but hey, I'm up for the challenge.
## Chasing the Cutting-Edge
Tax rules around crypto are like a moving target. One day you think you've got it figured out, then BAM! A new regulation drops. I need to stay on top of updates to tax software and all the latest legal stuff. Arch's rolling releases seem like they could be a lifesaver here.
## The AUR: Proceed with Caution
Okay, the Arch User Repository is kinda blowing my mind. It's like this hidden marketplace for anyone who's ever thought, "Wow, I wish there was a super niche tool to calculate exactly this weird crypto tax scenario." But the thing with community-made stuff is you gotta be extra careful. Security is no joke when it comes to tax data.
## Embracing My Inner Tech Nerd
The truth is, figuring out how Arch Linux works is scratching an itch I didn't know I had. I'm geeking out over the command line and digging into blockchain concepts on the Arch Wiki. At first, I wondered if this was a distraction from my actual tax work. But now I think understanding how these systems work under the hood can only make me better at analyzing their tax implications.
## The Big Question
So, is Arch the ultimate power-up for digital asset taxation and development? The jury's still out for me. But if you're the type who thrives on customization, isn't afraid to get your hands dirty with tech, and loves the thrill of the chase when it comes to new tools, it might be worth investigating.
What do you guys think? Anyone else out there experimenting with Arch or have an OS they swear by for this kind of work? Let's chat in the comments!

We also gazed on why it is needed, how to utilize this functionality, and a tutorial example of implementing the iterators and generators.
If you are not familiar with this concepts then I would request you all to check out my previous article on **[Iterators and Generators](https://dev.to/naineel12/iterators-and-generators-in-javascript-1ip9)**.
Now that you are familiar with iterators and generators, let's look at asynchronous ones (I swear this won't be a huge one :D).
##Async Iterators
In JavaScript, async iterators are an extended functionality of the normal iterators. To make an object an async iterable, it must implement the async iterable protocol, which is indicated by the presence of the `Symbol.asyncIterator` method. This method should return a `next` method which should return a Promise which will essentially fetch the data from the desired endpoint by performing asynchronous operation.
Let's take a look at coded example of the same to grasp the concept in better manner -
```javascript
const someKindOfAsyncOperation = async (id) => {
return new Promise((res, rej) => {
setTimeout(() => {
res(`Returning data of User: ${id}`)
})
})
}
const obj = {
[Symbol.asyncIterator] : async function* (){
for(let i = 0; i < 5; i++){
const value = await someKindOfAsyncOperation(i);
yield value;
}
}
};
(async () => {
for await (const value of obj) {
console.log(value); //Returning data of User: 0 ...
}
})();
```
Here, `someKindOfAsyncOperation` is an asynchronous operation which loosely relates to the API calls for fetching the user details. We have used generators way of implementing the iterators because of its usability.
During the asynchronous operation, the function will be halted at the `yield` keyword until the `for...of` loop calls for the `next` method of the object `obj`. The code structure remain very similar, the major changes are the introduction of the asynchronous operations.
##Async Generators
Async Generators are very useful for implementing Async Iterators. It removes the boilerplate code that we had to write every time implementing Iterators or Async Iterators.
Well for the spoilers, we have already made use of the Async Generator earlier in this article. So let's just dive right into it -
```javascript
const someKindOfAsyncOperation = async (id) => {
return new Promise((res, rej) => {
setTimeout(() => {
res(`Returning data of User: ${id}`)
})
})
};
async function* asyncGenerator() {
for (let i = 0; i < 5; i++) {
const value = await someKindOfAsyncOperation(i);
yield value;
}
};
(async () => {
for await (const value of asyncGenerator()) {
console.log(value); //Returning data of User: 0 ...
}
})();
```
Here in the code, the IIFE will be called, which will call the `next` method obtained from the `asyncGenerator()` and it will call the asynchronous function `someKindOfAsyncOperation` which upon resolving gives the desired output. and then `for await...of` loop will call the `next` function again which will yield the next value from the `asyncGenerator` generator function and so on and so forth, all of the desired output will be obtained in the way we want.
For simplicity sake we have used a mock asynchronous operation, we can easily extend this kind of functionality to fetch sequential or custom data.
So... **THANK YOU!!**🎉🫡
I would like to thank you for reading till here and appreciate your patience. It would mean the world to me if you give feedbacks/suggestions/recommendations below.

## what is Css Box Model ?
Above is a Visual Representation of what the box Model is about.
> The CSS box model is a fundamental concept in web development that defines how HTML elements are displayed and positioned on a web page. It's essentially a mental model that browsers use to render each element as a rectangular box with four key components.
**The Components of Css Box Model**
The components of css Box Model are based on quadri elements. these quadri elements form the basis for css box Model
> 1.Content 2.Padding 3.Border 4.Margin
**Content:** _This is the core information within the element, like text, images, or forms. You can control the content size using properties like width and height._
**Padding:** _Padding creates a transparent area around the content, providing space between the content and the border. You can set the padding using the padding property._
**Border:**_The border surrounds the content and padding, adding a visual distinction to the element. You can control the border style, color, and thickness using the border property._
**Margin:** _Margin is a transparent area outside the border that creates space between the element and other elements on the page. You can control the margin using the margin property_
**Implications of Understanding Css Box Model**
Understanding the box model is crucial for styling and positioning elements on a webpage. It allows you to control the spacing, borders, and overall dimensions of each element.
**Enumerate the Variations of Css Box Model**
There are two main variations of the box model:
1. Standard box model
2. Border-box model
**Standard box model**: This is the default behavior in most browsers. The width and height properties only define the content area size, and padding and border add to the total size.
**Border-box model**: Using the box-sizing: border-box property, the width and height properties define the total size of the element, including padding and border. The content size adjusts within the remaining space.
**The Differences between Standard & Border-box**
The key difference between the standard box model and the border-box model lies in how the width and height properties are interpreted: Let me Explain Please 🙇🏿♂️🙇🏿♂️🙇🏿♂️
In the standard box model Width and height define the size of the content area only.Padding and border add to the total size of the element.
While in the Border-box model Width and height define the total size of the element, including padding and border.The content area shrinks to fit within the remaining space after accounting for padding and border
**Which model is most beneficial?**
You say beneficially i say less Painstaking, In most cases, the border-box model is considered the more beneficial approach for several reasons:
**Easier Calculations**: _Setting the width and height to the desired total size simplifies calculations and avoids confusion about adding padding and border sizes_.
**Consistent Layouts**: _Elements with padding and borders will have consistent sizing across different browsers that support border-box (which is now the default in most browsers)._
**Responsive Design:** _The border-box model is particularly beneficial for responsive design, where you might adjust padding and borders based on_
**screen size**. _Consistent sizing ensures the content adapts properly._
##Summary & Highlight
The CSS box model is a fundamental concept in web development that shapes how elements appear on a webpage. It acts like a box with four key components:
* **Content:** The core information within the element (text, images, forms).
* **Padding:** Transparent space around the content for extra breathing room.
* **Border:** Visual distinction surrounding the content and padding.
* **Margin:** Transparent space outside the element for separation from other elements.
Understanding both the standard and border-box models is crucial:
* **Standard box model (default):** Width and height define the content area size, with padding and border adding to the total element size.
* **Border-box model:** Width and height define the total element size (including padding and border). The content adjusts to fit within the remaining space.
While the standard box model is the historical default, the border-box model offers several advantages:
* **Simpler calculations:** Total size is defined directly by width and height.
* **Consistent layouts:** Ensures consistent element sizing across browsers.
* **Responsive design friendly:** Content adapts well to different screen sizes.
By grasping both models, you can achieve predictable and well-structured layouts for your webpages.

Applications that constitute a database allow users to interact with the application’s data through **Object Relational Mappers (ORMs)**. ORMs are the intermediaries between an application and a database. They provide a set of functionality that enable [CRUD](https://www.codecademy.com/article/what-is-crud) database operations. Many server-side programming frameworks like Python’s Django provide ORMs that allow developers to write database queries in the pure server-side language. The ORM then performs a database operation in a language understood by the database type in use. This article discusses the Django ORM, including the functionalities that the ORM provides to facilitate database interactions.
## A Brief Overview
When building a backend application using Django, you would typically install Django in a virtual environment. Django installs a SQLite database by default, which comes with the Django ORM to allow database operations. You may have interacted with the Django ORM functionality without noticing. For instance, every time you have used `.get()` or `.filter()` methods somewhere in your views.py file, you were using Django ORM methods to query the database.
Django ORM methods can broadly be classified into two types:
* Those that interact with a queryset
* Those that interact with a model object
In simple terms, a queryset is single or several database records. A database record is basically a data row in a database. Therefore, queryset methods act on database records. A model object is an instance, or a definition if you may, of a database record. A model object provides information about a database record. That is, what [fields](https://www.inetsoft.com/info/database-fields-and-types/) does the database record have? For instance, a database record could have ID, name, URL, image or Foreign Key fields. Django ORM has methods that can manipulate these database record fields.
## Django ORM Methods
This section discusses the most commonly used Django ORM methods. The methods are grouped based on related functionality. That is, the methods that perform a similar functions are discussed together. Note that based on the broad classification discussed above, methods within the same category could interact with either a queryset or a model object.
### Filtering Methods
Filtering methods return querysets depending on the lookup parameters passed to the methods.
#### `.filter(**kwargs) `
`.filter()` returns a queryset that matches the lookup parameters passed to the method. For instance, assume you are a querying a database field, **name**, for all database records containing the name **bob**. In this case you would need to filter your database by **bob** as a **keyword argument**. Django ORM provides a magic method, **__icontains**, that attaches to a database field, which is useful for string and substring matching. You would implement this operation like this:
```python
from models import YourModel
bob_records = YourModel.objects.filter(name__icontains="bob")
```
Another common example where you would use `.filter()` is when you have implemented user accounts in your Django application. You may want to restrict each user to their data. In this case, if a user requests some data, you want to show them only the data that belongs to them. You would typically use `.filter()` method to avail data by the user making the request:
```python
your_data = YourModel.objects.filter(owner=request.user)
```
Assuming in your data model you have a field called `owner` that associates data and users
#### `.excludes(**kwargs): `
Works the same way as `.filter()` but returns database records that do not match the lookup parameters.
#### `.get(**kwargs):`
This method is among the most commonly used. Like .`filter()`, the method is used to retrieve the data that matches the lookup parameters passed to it as keyword arguments. However, `.get()` returns only a single database record while `.filter()` returns one or more records. `.get()` raises a [`MultipleObjectsReturned`](https://docs.djangoproject.com/en/5.0/ref/exceptions/) error or [`DoesNotExist`](https://docs.djangoproject.com/en/5.0/ref/exceptions/) error exception if multiple objects are found or no object is found, respectively. Below is an example of how you would use `.get()`
```python
data = YourModel.objects.get(id=1)
```
This queryset returns a database record with an id 1
#### `.first()`
Returns the first object matched by the queryset or `None` if the queryset is empty.
#### `.last()`:
Returns the last object matched by the queryset or `None` if the queryset is empty.
`.first()` and `.last()` are usually used with `.filter()` incase one needs only the first or the last item returned by .filter():
```python
bob_records = YourModel.objects.filter(name__icontains="bob", owner=request.user).first()
```
### Aggregation Methods
Aggregation methods perform arithmetic calculations on querysets. They include:
#### `aggregate(*args, **kwargs)`:
Performs aggregate calculations (e.g., `Count`, `Sum`, `Avg`, etc.) on the queryset
#### `.count()`
returns the number of objects in a queryset
#### `.exists()`
Evaluates to true if a queryset contains any results, else false. This method could be combined with `.filter()` in a real-world use case. Assume you want to add a record to the database, but only if no similar record already exists. Say you want to add a name bob to a database field name:
```python
If not YourModel.objects.filter(name="bob").exists():
model_instance = YourModel(name="bob")
```
### Ordering Methods
Ordering methods sort a queryset based on declared model fields.
Assume you have this model
```python
class Names(models.Model):
Name = models.CharField(max_length=200)
date_added = models.DateTimeField(auto_now_add=True)
```
`Names.objects.order_by('date_added')`: returns a queryset based on the date they were added to the database. The first added entry is returned first. Assuming you want to return a queryset based on the most recently added record, you would reverse the order like this:
```python
Names.objects.order_by('-date_added'). # The '-' sign indicates 'reverse'
```
Alternatively, Django ORM provides a .reverse() method for reversing the order of querysets:
```python
Names.objects.order_by('date_added').reverse()
```
Alternatively, you could sort the entries of the above model like this:
```python
class Meta:
Ordering = ['date_added']
```
In this case, you provide a Meta class inside your model class and define the desired ordering using the attribute ordering
### Update and Delete
Methods for updating or deleting objects in the database.
`.update(**kwargs)`: Updates all objects(fields) in the queryset with the given values.
```python
YourModel.objects.get(id=1).update(name="bob")
```
The above query updates the model field "name" with value "bob"
You can update more than one field with .update()
```python
YourModel.objects.get(id=1).update(name=”bob”, gender=”male”)
```
`.delete()`: Deletes all objects in the queryset.
```python
YourModel.objects.get(id=1).delete()
```
The above query deletes a database record with id 1. Note that while `.update()` can act on a part of a database record(a field), `.delete()` acts on the entire record(all fields);`.delete()` erases the entire record at once from the database.
### Other Methods
`.values(*fields, **expressions)`: Returns a queryset that returns dictionaries instead of model instances, with values according to the specified fields and expressions.
`.values_list(*fields, flat=False)`: Similar to `values()` but returns tuples instead of dictionaries.
`.values()` and `.value_list()` are helpful when you want to return specific database fields while excluding others.
Assume you have this model:
```python
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
class PasswordEntry(models.Model):
"""Defines password's data structure"""
website_url = models.URLField(max_length=200)
username = models.CharField(max_length=100)
password = models.CharField(max_length=500)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
owner = models.ForeignKey(User, on_delete=models.CASCADE, default=1)
class Meta:
ordering = ['-created_at']
verbose_name_plural = 'password entries'
def __str__(self):
"""Returns a string rep of password entry"""
return f"{self.username}-{self.website_url}-{self.password}"
```
This is a password entries model that allows a user to store passwords to their various user accounts. If you are building a similar Django application, you may want to implement a functionality that allows users to search for specific passwords. In this application, you may want to display the password entries by website URL or username instead of the actual password, for security reasons
Your search functionality may look something like this. Notice how `.values_list()` comes in handy when you want to choose the fields to display:
```python
def search_entry(request):
"""Searches for a password entry by site name"""
query = request.GET.get('q')
if query:
entries = PasswordEntry.objects.filter(website_url__icontains=query, owner=request.user).values_list('id', 'website_url')
else:
entries = PasswordEntry.objects.filter(owner=request.user).values_list('id', 'website_url')
context = {'entries': entries}
return render(request, 'manager/search_entries.html', context)
```
`.values_list()` and `.values()` act on model instances instead of querysets. Attempting to apply the methods on querysets will raise an attribute error.
## Conclusion
Object relational Mappers (ORMs) are a useful technology. They allow backend developers to query databases without having to write raw statements in a standard database query language like Structured Query Language (SQL). ORMs, therefore, reduce the chances of database injection attacks. The attacks can occur if users access the database directly using languages like SQL. Moreover, developers do not have to necessarily understand a query language; ORMs conduct most of the heavy lifting.
Django provides its own ORM, the Django ORM. The Django ORM avails different types of methods that enable developers to perform CRUD operations on the database. The methods perform operations such as filtering, aggregation, ordering, updating and deleting. Several errors are bound to rise if the methods are used inappropriately. This article mentions several errors such as AttributeError, MultipleObjectsReturnedError and DoesNotExistError. Nevertheless, the Django ORM is a powerful tool for executing database transactions.

You will become the richest and happiest person in the world. But is it possible? Yes, through reading.
**Reading** is one of the most difficult skills to maintain consistency. Maybe you also stopped reading a book in half due to various distractions.
According to the following statistics, the average number of readers is decreasing in the US year by year.
So what are the reasons behind people stepping back from reading?
## Why do we Stop Reading?
The most important reason is the introduction of **social media**. Social media eats up the time people dedicate to reading books.
Users are used to skimming through streams of short, attention-spanning content. The shorter attention span leads to the inability to do longer tasks, like reading a lengthy book.
Some other reasons are:
* procrastination
* a lack of self-discipline
* availability of space and time
Everybody has a desire to improve their capabilities and skills by reading and applying a lot of books.
**Procrastination** is a major obstacle to building any skill. Aligning our mindsets to defeat procrastination is one of the most painful tasks.
Procrastination for reading can also happen due to various other distractions, such as social media, doom scrolling, etc.
One of the other main reasons people will say to stop reading is the availability of time and space.
Between work, family, and different chores, most people find time to allocate for reading. Also, reading a lengthy book will take months to complete.
But it doesn't mean building a reading habit is a non-solvable problem.
If we follow a systematic method and have a proper mindset, anybody can achieve any skill, including consistent reading.
If you follow the solution that I'm going to suggest here for **10 minutes every day**, you can read at least 10 books in 60 hours.
## Reading 2x Books this Year
To address the reading problem and create a consistent reading habit in our internal team, we built a tool called **[FeedZap](https://hexmos.com/feedzap)**.
[FeedZap](https://hexmos.com/feedzap) is a free software tool that helps to build a reading habit with less effort and time.
[FeedZap](https://hexmos.com/feedzap) has so many features that help you maintain consistency in reading and transform your readings into learning.
Let's see how the different features in FeedZap help you build a consistent reading habit by **investing 10 minutes daily**.
## Replace Distractions into Learning
In the days before social media, people used their free time to read a lot of books. Getting that habit back is very difficult in this era.
The **stream of content through the feed** is the most addictive feature on any social media. So what if we can replace the addictive social media feed with an informative, healthy feed? That's what FeedZap is doing.
[FeedZap Chrome extension](https://chromewebstore.google.com/detail/hfmhadkhbkjnfkldmfholhihelodmapp?utm_source=ext_app_menu) will replace your social media feeds, such as Reddit, LinkedIn, and Twitter, with more informative, healthy feeds from your favorite books.

[게임 업계도](https://www.pubnub.com/solutions/gaming/) 마찬가지인데, 게임 개발자에게 3D 모델, 애니메이션, 스토리라인 등 뛰어난 콘텐츠를 간소화되고 자동화된 방식으로 제작할 수 있는 놀라운 툴박스를 제공하고 있기 때문입니다. 뿐만 아니라 게임 테스트 절차와 게임 자체의 기본 메커니즘도 개선하고 있습니다. 게임 개발자를 위한 제너레이티브 AI의 흥미로운 잠재력에 대해 자세히 알아보려면 계속 읽어보세요.
**미리** 알려드립니다: 게임 산업을 변화시킬 수 있는 제너레이티브 AI의 잠재력은 엄청납니다. 개발자에게 콘텐츠 제작을 위한 다양하고 새로운 도구와 기술을 제공합니다. 하지만 제너레이티브 AI로 인한 윤리적 우려도 존재합니다. 가장 큰 우려는 다른 게임의 아트, 사운드, 에셋을 실수로 베낄 수 있는 위험, 즉 일종의 AI 기반 표절입니다. 이러한 함정을 피하려면 다양한 데이터 세트를 바탕으로 생성 AI 모델을 훈련하는 것이 중요합니다. 또한 생성되는 콘텐츠가 고유하고 타인의 지적 재산권을 존중하는지 항상 확인해야 합니다.
프로시저럴 콘텐츠 생성을 위한 제너레이티브 AI
--------------------------
절차적 콘텐츠 생성(PCG)은 게임 개발에서 게임 콘텐츠를 수동이 아닌 알고리즘으로 생성하는 데 사용되는 기법입니다. 이 방법을 사용하면 게임 개발자는 모든 플레이어에게 고유한 월드, 아이템, 적, 플레이를 만들 수 있습니다.
[노 맨스 스카이](https://www.nomanssky.com/), [마인크래프트](https://www.minecraft.net/), [드워프 포트리스](http://www.bay12games.com/dwarves/) 등 수년 전부터 PCG는 게임에 존재해 왔지만, 제너레이티브 AI는 머신러닝 알고리즘과 신경망을 기반으로 개발자가 더욱 독특하고 복잡한 콘텐츠를 제작할 수 있도록 PCG를 크게 발전시켰습니다. 제너레이티브 AI를 사용하면 개발자는 최소한의 수동 입력으로 방대하고 복잡한 월드를 제작할 수 있어 더욱 역동적이고 재생 가능한 게임 경험을 제공하고, 재플레이를 유도하며, 커뮤니티에 대한 유대감을 형성할 수 있습니다.
제너레이티브 AI와 다이내믹 스토리텔링
---------------------
제너레이티브 AI는 플레이어의 선택과 행동에 따라 진화하는 적응형 인터랙티브 내러티브를 제작하는 데 사용할 수 있습니다. 여러 게임에서 제너레이티브 AI를 사용하여 역동적인 내러티브를 제작하거나 이 접근 방식의 잠재력을 선보이기 시작했습니다.
[Facade는](https://www.interactivestory.net/) 자연어 처리와 AI 기술을 사용하여 플레이어의 선택과 대화 입력에 따라 여러 가지 엔딩이 가능한 역동적인 스토리를 만드는 인터랙티브 내러티브 게임입니다. [AI 던전은](https://play.aidungeon.io/) OpenAI의 GPT-3.5 모델로 구동되는 텍스트 기반 어드벤처 게임으로, 플레이어의 텍스트 입력과 선택에 따라 각 플레이어에게 고유한 인터랙티브 스토리를 생성합니다.
이 게임과 다른 게임들은 정적이고 미리 정해진 내러티브에서 벗어나 플레이어의 행동과 선택에 따라 변화하는 역동적이고 진화하는 스토리로 전환하기 시작했습니다. 머신러닝 알고리즘과 신경망을 활용하는 제너레이티브 AI는 플레이어의 행동에 반응하는 스토리라인을 생성하여 더욱 몰입감 있고 개인화된 게임 경험을 제공할 수 있습니다.
테스트 및 품질 보증에서 제너레이티브 AI의 역할
---------------------------
제너레이티브 AI는 콘텐츠 제작과 스토리텔링에 적용될 뿐만 아니라 게임 개발의 테스트 및 품질 보증(QA) 프로세스를 개선하는 데도 중요한 역할을 할 수 있습니다.
제너레이티브 AI는 게임 테스트의 다양한 측면을 자동화하는 데 사용할 수 있으며, 효율성과 정확성 측면에서 여러 가지 이점을 제공합니다.
- 테스트 케이스 생성: AI 모델을 학습시켜 다양한 테스트 케이스를 생성함으로써 게임의 다양한 측면을 철저하게 테스트할 수 있습니다.
- 버그 식별 및 우선순위 지정: AI는 개발자가 버그를 더 빠르고 정확하게 식별하고, 버그의 심각도와 게임에 미치는 영향에 따라 우선순위를 지정하는 데 도움을 줄 수 있습니다.
- 예측 분석: AI는 게임플레이 데이터를 분석하여 잠재적인 문제를 예측할 수 있으므로 개발자는 심각한 문제로 발전하기 전에 선제적으로 문제를 해결할 수 있습니다.
여러 게임사와 게임 개발사가 테스트 및 QA 프로세스에서 AI를 활용하는 방안을 모색하기 시작했습니다. [Ubisoft는](https://www.ubisoft.com/en-us/) 수동 테스트 작업을 줄이고 제품의 전반적인 품질을 개선하기 위해 AI 기반 테스트 도구를 실험하여 게임의 QA 프로세스를 개선하고 있습니다. 일렉트로닉 아츠의 연구 부서인 [SEED(Search for Extraordinary Experiences Division](https://www.ea.com/seed))는 플레이어에게 더욱 사실적이고 역동적인 게임플레이 경험을 제공하기 위해 테스트 및 품질 보증을 위한 AI 기반 기법을 연구해 왔습니다.
개발자는 AI 알고리즘과 머신러닝 기술을 활용하여 버그 및 기타 문제를 감지하고 수정하는 과정을 간소화함으로써 플레이어에게 더욱 세련되고 정교한 게임 경험을 제공할 수 있습니다.
실시간 적응을 위한 제너레이티브 AI
--------------------
제너레이티브 AI는 플레이어의 선호도, 기술 수준, 플레이 스타일을 분석하여 게임 난이도와 경험을 동적으로 조정함으로써 더욱 매력적이고 개인화된 게임플레이를 제공할 수 있습니다.

1,793,373 | Login with Google on React Native Expo | This will work for web, IOS and Adnroid Create a new expo project: npx create-expo-app... | 0 | 2024-03-18T02:52:38 | https://dev.to/angela300/login-with-google-on-react-native-expo-3h9n | This will work for web, IOS and Adnroid
Create a new expo project:
`npx create-expo-app tutorial-google`
Install dependencies that we will need
Expo auth session will manage the sign in with Google
Expo-crypto and expo-web-browser are core dependencies of expo-auth-session
We will also need react-native-web, react-dom and @expo/webpack-config
We will also need react native async storage
`npx expo install expo-auth-session expo-crypto expo-web-browser react-native-web react-dom @expo/webpack-config @react-native-async-storage/async-storage`
Create a project in Google cloud:
Select the project
We are going to create an OAuth client ID
Go to API’s and services and click on OAuth consent screen
On enable APIs & services, click on Create credentials:
After clicking on Create credentials, on the dropdown screen that comes up, click on OAuth Client ID
Next click on configure consent screen
Click on External - availabe to any User with a Google test account and click on create.
This is the consent screen
Under app name, fill in ‘google-tutorial’ or your preferred name
Under user support email, provide one
You can specify a logo, app domain, which are all optional
Under developer contact information, add another email
Hit on save and continue
Under scopes, you can add users if you want.
Click on save and continue
Now we have a consent screen.
Lets get a client id for the web:
Click on credentials, and under application type, click on Web application:
Under authorized Javascript Origins, we need to add some URL’s, which are the URL’s for the application
To get the URL, run the project on the web:
`npx expo start –web –https`
The app will open in the web, copy that URL and add it:
https://localhost:19006
This is the same link under Authorized Redirect URI’s
Click on ‘Create’
On the screen that pops up, Copy the Client ID
On the App.js file in your Expo app, paste the client ID on there for later use.
Lets also get the ID’s for IOS:
Click on create credentials, Click on OAuth Client ID, the select IOS under Application type
For IOS, we will need the bundle ID.
On your app’s root folder:
Run the command, `npx expo prebuild`
Under the package name add: com.betomoedamo.tutorialgoogle
We also have the IOS Identifier which is going to be the same as package name above
Hit Enter
Once this is completed, we can see that the bundle identifier has been added under IOS:
Copy that bundle Identifier and paste it in the Bundle ID field under Create OAuth Client ID:
Hit create, and on the popup screen that comes up, copy the client ID.
Paste for later use in your App.js file, just as you did with the client ID for the web
Create a credential for Android
Click on create credentials, Click on OAuth Client ID, the select Android under Application type
Under package name, paste the name attached to “package” under android in app.js. It will the same as the Bundle ID for IOS
We will also need a SHA-1 certificate fingerprint
To obtain this for android,
run this command in your app’s root folder: `expo credentials:manager`
Under platform, select Android
Under ‘You are currently in a directory with @betomoedano/tutorial-google experience. Do you want to select it?...’, Select Yes
Under ‘What do you want to do?’ Select Update upload Keystore
Then select Generate new keystore
Select on Go back to the experience overview, and here, we have the SHA-1 fingerprint
Copy the SHA-1 certificate fingerprint and paste it under the required field in creating credentials.
Hit create and on the pop up screen that comes up, copy the client ID an paste it your App.js file for later use
That was the most difficult part, now we can start creating the code for the application
In app.js, import WebBrowser:
`Import * as WebBrowser from “expo-web-browser”`
Initialize the WebBrowser with this command:
`WebBrowser.maybeCompleteAuthSession();`
Also add this import in your app.js:
`Import * as Google from “expo-auth-session/providers/google”`
To save the information of the user when they sign in so that they do not have to sign in again, we will use async storage:
`Import AsyncStorage from “@react-native-async-storage/async-storage”`
Also add this to the imports section:
`Import * as React from “react”`
Add a variable userInfo and initialize it to null:
`Const [userInfo, setUserInfo] = React.useState(null);`
Next, lets create a hook that is going to enable us to signin in all of our applications:
Here will now add the client ID’s we had saved for later use.
```
Const [request, response, promptAsync] = Google.useAuthRequest({
})
```
Populate the above array to appear as this:
We will need to prompt the user to signin with Google, by adding this button in the app:
<Button title=”Sign in with Google” onPress={promptAsync}/>
Let’s now run the app on the web and see:
This is working, though it’s not handling the response,
Let’s go back to the application and handle the response
We will need to create a get userinfo function and a handlesigninwithgoogle function:
The getuserinfo function is called inside the signinwithgoogle function.
To run the signinwithgoogle function, we will now need to create a useEffect hook:
To enable sign out, lets add a button to delete local storage:
We added the json.Stringify(userInfo) above to test if the sign in and delete local storage are working. You can test them out and see.
Test on the web
On a successful sign in with google, we have all the information about the user:
Also test if its working on IOS and android:
To test it in android and IOS, we need to provide a scheme, which will help us redirect the user back to the application
Add the scheme into your app.json as shown below:
You can name the scheme as you want. In my case, I named it ‘myGoogleApp’
A) Test on IOS
Next we need to build the app:
To build for IOS, run the command, npx expo run:ios
With no user signed it yet, the userInfo will be null:
On proceeding to signin with google, you might encounter this error:
To remove the error, edit your sign in with google button to appear as this:
To also ensure the userinfo appears in a nice format, edit the text stringify to appear as this:
b) Test on android:
Now also text if its working on android.
We need to create the actual build for android: npx expo run:android
Before sign in, it will appear like this in android:
Upon a successful sign in, it will appear as follows:

---
Son amplias las funcionalidades que ofrece AWS para mantener nuestro código de manera segura y protegida, [AWS signer](https://docs.aws.amazon.com/signer/latest/developerguide/Welcome.html) es un servicio que permite firmar el código de algunos servicios de AWS entre los que se encuentra [AWS Lambda](https://aws.amazon.com/es/pm/lambda/).
Existe una amplia variedad de herramientas de infraestructura como código (IaC) para gestionar nuestra infraestructura, [terraform](https://www.terraform.io/) es una de las herramientas ms difundidas para gestionar infraestructura.
A continuacin veremos como configurar [AWS signer](https://docs.aws.amazon.com/signer/latest/developerguide/Welcome.html) con [terraform](https://www.terraform.io/) para firmar el código de una lambda y veremos su funcionamiento asegurando nuestro código.
# Repositorio:
Todo el código está en el siguiente repositorio que pueden descargar y seguir para desplegar la `POC` en su entorno de prueba:
> [https://github.com/olcortesb/terraform-lambda-signer/tree/main](https://github.com/olcortesb/terraform-lambda-signer/tree/main)
## Configurar terraform:
La versión de [terraform](https://www.terraform.io/) que utilizaremos es la `1.5.5`
```bash
terrafom --version
# is 1.7.5. You can update by downloading from
# https://www.terraform.io/downloads.html
```
Configuramos el `bucket` de `s3` que hemos creado para esta prueba, en el archivo `preferences.tf` el parámetro `backend.bucket`
```js
// file terraform-lambda-signer/preferences.tf
terraform {
required_version = ">=1.5.0"
required_providers {
aws = {
source = "hashicorp/aws"
version = ">= 4.9"
}
}
backend "s3" {
key = "terraform.tfstate"
bucket = "terraform-lambda-signer" // change the name of bucket
region = "us-east-1"
}
}
```
## Configurar AWS CLI
Necesitamos tener configurada una cuenta de `AWS`, aquí un pequeño `gist` de como se configura [Link](https://gist.github.com/olcortesb/a471797eb1d45c54ad51d920b78aa664)
## Configurando AWS signer
Para configurar `AWS signer` necesitamos
### Definir el `signing_profile`:
```
AWSIoTDeviceManagement-SHA256-ECDSA
AWSLambda-SHA384-ECDSA
AmazonFreeRTOS-TI-CC3220SF
AmazonFreeRTOS-Default
```
Elegimos la que corresponde a Lambda y creamos el recurso:
```js
// File lambda.tf
resource "aws_signer_signing_profile" "tfsigner" {
name_prefix = "tfsigner"
platform_id = "AWSLambda-SHA384-ECDSA"
}
```
### Configurar el `signing_job`:
Para definir el `signig job` necesitamos el origen del `bucket` y el objeto `s3` y agregarle un destino donde tendremos el código firmado.
```js
// File lambda.tf
resource "aws_signer_signing_job" "this" {
profile_name = aws_signer_signing_profile.tfsigner.name
source {
s3 {
bucket = aws_s3_bucket.lambda_code_bucket.id
key = aws_s3_object.lambda_code.id
version = aws_s3_object.lambda_code.version_id
}
}
destination {
s3 {
bucket = aws_s3_bucket.lambda_code_bucket.id
prefix = "signed/"
}
}
ignore_signing_job_failure = true
}
```
### Definir la configuración del `signer` para Lambda:
```js
// File lambda.tf
resource "aws_lambda_code_signing_config" "tfsigner_code" {
allowed_publishers {
signing_profile_version_arns = [aws_signer_signing_profile.tfsigner.version_arn]
}
policies {
untrusted_artifact_on_deployment = "Enforce"
}
}
```
### Agregar al `resource` de lambda la configuración del `signer`
```js
// file lambda.tf
// Lambda
resource "aws_lambda_function" "lambda" {
// ...
// Signer
code_signing_config_arn = aws_lambda_code_signing_config.tfsigner_code.arn
// S3 for signer configurations
s3_bucket = aws_signer_signing_job.this.signed_object[0].s3[0].bucket
s3_key = aws_signer_signing_job.this.signed_object[0].s3[0].key
// ...
}
```
# Conclusiones
Con `AWS signer` tenemos la posibilidad de garantizar la integridad del código de nuestra lambda, teniendo un lugar único donde definir el entorno de firma como sus roles y propiedades que no abordamos en esta `POC`, pero que se pueden configurar.
El código queda completamente trazado y la integridad del mismo permite tener un control sobre los cambios que se realizan sobre l.
La configuración desde `terraform` es simple y puede automatizarse de manera eficiente para los distintos entornos de desarrollo que tengamos
Respecto al coste, `AWS Signer` no tiene cargo adicionar como se puede revisar en la documentación oficial [Link](https://docs.aws.amazon.com/signer/latest/developerguide/whatis-pricing.html)

Title: Uncovering the Rich Embroidery of Lahore: An Excursion Through History
Presentation:
Settled along the banks of the Ravi Stream, Lahore remains as a demonstration of Pakistan's rich social legacy and verifiable importance. With a set of experiences traversing north of a thousand years, Lahore has seen the ascent and fall of realms, the conversion of different societies, and the development of a lively city. In this article, we leave on an excursion through opportunity to investigate the enrapturing history of Lahore, from its old beginnings to its cutting edge engage.
Antiquated Beginnings:
The starting points of Lahore can be followed back to relic, with archeological proof recommending human home in the district tracing all the way back to the Paleolithic period. Notwithstanding, it was during the standard of the amazing Head Akbar in the sixteenth century that Lahore rose to noticeable quality as the capital of the Mughal Realm. Under Akbar's support, Lahore prospered as a focal point of workmanship, engineering, and getting the hang of, abandoning a tradition of grand landmarks, for example, the Lahore Post and the Badshahi Mosque.
Mughal Magnificence:
The Mughal period denoted a brilliant age for Lahore, as the city turned into a signal of culture and refinement in South Asia. Head Shah Jahan, famous for his building ability, embellished Lahore with notable tourist spots like the Shalimar Nurseries and the impeccable Wazir Khan Mosque. The Lahore Stronghold, with its many-sided marble decorates and lofty royal residences, turned into the exemplification of Mughal loftiness, drawing in guests from all over.
Pioneer Inheritance:
The nineteenth century saw Lahore fall under English pioneer rule, introducing another section in its set of experiences. The English changed Lahore into a cutting edge city with an organization of streets, railroads, and instructive establishments. The famous Lahore Gallery, established in 1865, turned into a vault of the district's rich social legacy, exhibiting curios from different times of history. Notwithstanding the disturbances of imperialism, Lahore held its social energy, mixing Eastern persona with Western impacts.
Segment and Freedom:
The parcel of English India in 1947 significantly affected Lahore, as the city turned into a milestone for the battles of freedom and character. The mass relocation that went with parcel made a permanent imprint on Lahore's social texture, as networks were evacuated and uprooted. Notwithstanding the injury of parcel, Lahore arose as a versatile city, embracing its multicultural legacy and remaking itself as an image of trust and flexibility.
Present day Renaissance:
Soon after freedom, Lahore encountered a social renaissance, filled by a prospering expressions scene and a recharged deep satisfaction in its legacy. The old city, with its twisted roads and clamoring marketplaces, turned into a center point of imagination and business. The Lahore Scholarly Celebration, sent off in 2013, praises the city's scholarly heritage and fills in as a stage for discourse and trade.
End:
From its old starting points to its cutting edge dynamism, Lahore remains as a living demonstration of Pakistan's rich social embroidery. Through the back and forth movement of history, Lahore has stayed an image of strength, variety, and solidarity, epitomizing the soul of a country fashioned through hundreds of years of wins and hardships. As we explore the clamoring roads and celebrated tourist spots of Lahore, we are helped to remember the immortal charm of this memorable city, where the past consistently converges with the present, making an embroidery of unmatched excellence and interest. | majid67011 |
1,793,961 | LangChain, Python, and Heroku | Since the launch and wide adoption of ChatGPT near the end of 2022, we’ve seen a storm of news about... | 0 | 2024-03-18T15:20:31 | https://dzone.com/articles/langchain-python-and-heroku | python, tutorial, ai, webdev | Since the launch and wide adoption of ChatGPT near the end of 2022, we’ve seen a storm of news about tools, products, and innovations stemming from large language models (LLMs) and generative AI (GenAI). While many tech fads come and go within a few years, it’s clear that LLMs and GenAI are here to stay.
Do you ever wonder about all the tooling going on in the background behind many of these new tools and products? In addition, you might even ask yourself how these tools — leveraged by both developer and end users — are run in production. When you peel back the layers for many of these tools and applications, you’re likely to come across **LangChain, Python, and Heroku**.
These are the pieces that we’re going to play around with in this article. We’ll look at a practical example of how AI/ML developers use them to build and easily deploy complex LLM pipeline components.
## **Demystifying LLM Workflows and Pipelines**
Machine learning pipelines and workflows can seem like a black box for those new to the AI world. This is even more the case with LLMs and their related tools, as they’re such (relatively) new technologies. Working with LLMs can be challenging, especially as you’re looking to create engineering-hardened and production-ready pipelines, workflows, and deployments. With new tools, rapidly changing documentation, and limited instructions, knowing where to start or what to use can be hard. So, let’s start with the basics of LangChain and Heroku.
The [documentation for LangChain](https://python.langchain.com/docs/get_started/introduction) tells us this: “*LangChain is a framework for developing applications powered by language models.*”
Meanwhile, [Heroku describes itself](https://www.heroku.com/what) this way: “*Heroku is a cloud platform that lets companies build, deliver, monitor, and scale apps — we’re the fastest way to go from idea to URL, bypassing all those infrastructure headaches.*”
If we put this in the context of building an LLM application, then LangChain and Heroku are a match made in heaven. We need a well-tested and easy-to-use framework (LangChain) to build our LLM application upon, and then we need a way to deploy and host that application (Heroku).
Let’s look into each of these technologies in more detail.
### **Diving into LangChain**
Let’s briefly discuss how LangChain is used. LangChain is a framework that assists developers in building applications based on LLM models and use cases. It has support for [Python](https://python.langchain.com/docs/get_started/introduction), [JavaScript](https://js.langchain.com/docs/get_started/introduction), and [TypeScript](https://blog.langchain.dev/typescript-support/). For example, let’s say we were building a tool that generates reports based on user input or automates customer support response. LangChain acts as the scaffolding for our project, providing the tools and structure to efficiently integrate language models into our solution.
Within LangChain, we have several key components:
* [**Agent**](https://python.langchain.com/docs/modules/agents/concepts): The agent is the component that interacts with the language model to perform tasks based on our requirements. This is the brain of our application, using the capabilities of language models to understand and generate text.
* [**Chains**](https://python.langchain.com/docs/modules/chains): These are sequences of actions or processes that our agent follows to accomplish a task. For example, if we were automating customer support, a chain might include accepting a customer query, finding relevant information, and then crafting a response.
* [**Templates**](https://blog.langchain.dev/langchain-templates/#:~:text=LangChain%20Templates%20offers%20a%20collection,add%20to%20this%20over%20time.): Templates provide a way to structure the outputs from the language model. For example, if our application generates reports, then we would leverage a template that helps format these reports consistently, based on the model’s output.
* [**LangServe**](https://github.com/langchain-ai/langserve): This enables developers to [deploy and serve](https://python.langchain.com/docs/langserve) up LangChain applications as a REST API.
* [**LangSmith**](https://smith.langchain.com/): This tool helps developers [evaluate, test, and refine](https://python.langchain.com/docs/langsmith/) the interactions in their language model applications to get them ready for production.
LangChain is a widely adopted framework for building AI and LLM applications, and it’s easy to see why. LangChain provides the functionality to build and deploy products end to end.
### **Diving into Heroku**
Heroku is best known as a cloud platform as a service (PaaS) that makes it incredibly simple to deploy applications to the cloud. Developers often want to focus solely on code and implementation. When you’re already dealing with complex data pipelines and LLM-based applications, you likely don’t have the resources or expertise to deal with infrastructure concerns like servers, networks, and persistent storage.
With the ability to easily deploy your apps through Heroku, the major hurdle of productionizing your projects is handled effortlessly.
## **Building with LangChain**
For a better understanding of how LangChain is used in an LLM application, let’s work through some example problems to make the process clear. In general, we would chain together the following pieces to form a single workflow for an LLM chain:
1. Start with a [prompt template](https://api.python.langchain.com/en/latest/prompts/langchain_core.prompts.prompt.PromptTemplate.html) to generate a prompt based on parameters from the user.
2. Add a [retriever](https://python.langchain.com/docs/modules/data_connection/) to the chain to retrieve data that the language model was not originally trained on (for example: from a database of documents).
3. Add a [conversation retrieval chain](https://api.python.langchain.com/en/latest/chains/langchain.chains.conversational_retrieval.base.ConversationalRetrievalChain.html) to include chat history, so that the language model has context for formulating a better response.
4. Add an agent for interacting with an actual LLM.
LangChain lets us “chain” together the processes that form the base of an LLM application. This makes our implementation easy and approachable. Let’s work with a simple example.
In our example, we’ll work with OpenAI. We’ll craft our prompt this way:
1. Tell OpenAI to take on the persona of an encouraging fitness trainer.
2. Input a question from the end user.
To keep it nice and simple, we won’t worry about chaining in the retrieval of external data or chat history. Once you get the hang of LangChain, adding other capabilities to your chain is straightforward.
On our local machine, we activate a virtual environment. Then, we install the packages we need:
```bash
(venv) $ pip install langchain langchain_openai
```
We’ll create a new file called [`main.py`](http://main.py). Our basic Python code looks like this:
```python
import os
from langchain_core.prompts import ChatPromptTemplate
from langchain_openai import ChatOpenAI
my_prompt = ChatPromptTemplate.from_messages([
("system", "You are a friendly and encouraging fitness trainer."),
("user", "{input}")
])
llm = ChatOpenAI(openai_api_key=os.getenv("OPENAI_API_KEY"))
chain = my_prompt | llm
```
That’s it! In this basic example, we’ve used LangChain to chain together a prompt template and our OpenAI agent.
To use this from the command line, we would add the following code:
```python
user_input = input("Ask me a question related to your fitness goals.\n")
response = chain.invoke({
"input": user_input
})
print(response)
```
Let’s test out our application from the command line.
```bash
(venv) $ OPENAI_API_KEY=insert-key-here python3 main.py
Ask me a question related to your fitness goals.
How do I progress toward holding a plank for 60 seconds?
content="That's a great goal to work towards! To progress
towards holding a plank for 60 seconds, it's important to
start with proper form and gradually increase the duration
of your plank holds. Here are some tips to help you
progress:\n\n1. Start with shorter durations: Begin by
holding a plank for as long as you can with good form,
even if it's just for a few seconds. Gradually increase
the time as you get stronger.\n\n2. Focus on proper form:
Make sure your body is in a straight line from head to
heels, engage your core muscles, and keep your shoulders
directly over your elbows.\n\n3. Practice regularly: Aim
to include planks in your workout routine a few times a
week. Consistency is key to building strength and
endurance.\n\n4. Mix it up: Try different variations of
planks, such as side planks or plank with leg lifts, to
work different muscle groups and keep your workouts
challenging.\n\n5. Listen to your body: It's important to
push yourself, but also know your limits. If you feel any
pain or discomfort, stop and rest.\n\nRemember, progress
takes time and patience. Celebrate each milestone along
the way, whether it's holding a plank for a few extra
seconds or mastering a new plank variation. You've got
this!"
```
*(I’ve added line breaks above for readability.)*
That’s a great start. But it would be nice if the output was formatted to be a bit more human-readable. To do that, we simply need to add an [output parser](https://python.langchain.com/docs/modules/model_io/output_parsers/) to our chain. We’ll use [`StrOutputParser`](https://api.python.langchain.com/en/latest/output_parsers/langchain_core.output_parsers.string.StrOutputParser.html).
```python
import os
from langchain_core.prompts import ChatPromptTemplate
from langchain_openai import ChatOpenAI
from langchain_core.output_parsers import StrOutputParser
my_prompt = ChatPromptTemplate.from_messages([
("system", "You are a friendly and encouraging fitness trainer."),
("user", "{input}")
])
llm = ChatOpenAI(openai_api_key=os.getenv("OPENAI_API_KEY"))
chain = my_prompt | llm | output_parser
user_input = input("Ask me a question related to your fitness goals.\n")
response = chain.invoke({
"input": user_input
})
print(response)
```
Now, at the command line, our application looks like this:
```bash
(venv) $ OPENAI_API_KEY=insert-key-here python3 main.py
Ask me a question related to your fitness goals.
How do I learn how to do a pistol squat?
That's a great goal to work towards! Pistol squats can be challenging but with practice and patience, you can definitely learn how to do them.
Here are some steps you can follow to progress towards a pistol squat:
1. Start by improving your lower body strength with exercises like squats, lunges, and step-ups.
2. Work on your balance and stability by practicing single-leg balance exercises.
3. Practice partial pistol squats by lowering yourself down onto a bench or chair until you can eventually perform a full pistol squat.
4. Use a support like a TRX band or a pole to assist you with balance and lowering yourself down until you build enough strength to do it unassisted.
Remember to always warm up before attempting pistol squats and listen to your body to avoid injury. And most importantly, stay positive and patient with yourself as you work towards mastering this challenging exercise. You've got this!
```
The LLM response is formatted for improved readability now.
For building powerful LLM applications, our chains would be much more complex than this. But that’s the power and simplicity of LangChain. The framework allows for the modularity of logic specific to your needs so you can easily chain together complex workflows.
Now that we have a simple LLM application built, we still need the ability to deploy, host, and serve our application to make it useful. As a developer focused on app building rather than infrastructure, we turn to LangServe and Heroku.
### **Serving with LangServe**
LangServe helps us interact with a LangChain chain through a REST API. To write the serving portion of a LangChain LLM application, we need three key components:
1. A valid chain (*like what we built above*)
2. An API application framework (such as [FastAPI](https://fastapi.tiangolo.com/))
3. Route definitions (just as we would have for building any sort of REST API)
The [LangServe docs](https://python.langchain.com/docs/langserve#server) provide some helpful examples of how to get up and running. For our example, we just need to use FastAPI to start up an API server and call `add_routes()` from LangServe to make our chain accessible via API endpoints.
Along with this, we’ll need to make some minor modifications to our existing code.
1. We’ll remove the use of the `StrOutputParser`. This will give callers of our API flexibility in how they want to format and use the output.
2. We won’t prompt for user input from the command line. The API call request will provide the user’s input.
3. We won’t call `chain.invoke()` because LangServe will make this part of handling the API request.
We make sure to add the FastAPI and LangServe packages to our project:
```bash
(venv) $ pip install langserve fastapi
```
Our final [`main.py`](http://main.py) file looks like this:
```python
import os
from langchain_core.prompts import ChatPromptTemplate
from langchain_openai import ChatOpenAI
from fastapi import FastAPI
from langserve import add_routes
my_prompt = ChatPromptTemplate.from_messages([
("system", "You are a friendly and encouraging fitness trainer."),
("user", "{input}")
])
llm = ChatOpenAI(openai_api_key=os.getenv("OPENAI_API_KEY"))
chain = my_prompt | llm
app = FastAPI(title="Fitness Trainer"")
add_routes(app, chain)
if __name__ == "__main__":
import uvicorn
uvicorn.run(app, host="localhost", port=8000)
```
On my local machine (Ubuntu 20.04.6 LTS) running Python 3.8.10, I also needed to install some additional packages to get rid of some warnings. You might not need to do this on your machine.
```bash
(venv) $ pip install sse_starlette pydantic==1.10.13
```
Now, we start up our server:
```bash
(venv) $ OPENAI_API_KEY=insert-key-here python3 main.py
INFO: Started server process [629848]
INFO: Waiting for application startup.
LANGSERVE: Playground for chain "/" is live at:
LANGSERVE: │
LANGSERVE: └──> /playground/
LANGSERVE:
LANGSERVE: See all available routes at /docs/
INFO: Application startup complete.
INFO: Uvicorn running on http://localhost:8000 (Press CTRL+C to quit)
```
Ooooh… nice!
In the browser, we can go to [http://localhost:8000/docs](http://localhost:8000/docs). This is what we see:
LangServe serves up an API docs page that uses a Swagger UI! These are the endpoints now available to us through LangServe. We *could* send a `POST` request to the `invoke/` endpoint. But LangServe also gives us a `playground/` endpoint with a web interface to work with our chain directly.
We provide an input and click **Start**. Here’s the result:
It’s important to stress the importance of having APIs in the context of LLM application workflows. If you think about it, most use cases of LLMs and applications built on top of them can’t rely on *local* models and resources for inference. This neither makes sense nor scales well.
The real power of LLM applications is the ability to abstract away the complex workflow we’ve described so far. We want to put everything we’ve done behind an API so the use case can scale and others can integrate it. This is only possible if we have an easy option to host and serve these APIs. And that’s where Heroku comes in.
## **Deploying to Heroku**
Heroku is the key, final part of our LLM application implementation. We have LangChain to piece together our workflow, and LangServe to serve it up as a useful REST API. Now, instead of setting up complex resources manually to host and serve traffic, we turn to Heroku for the simple deployment of our application.
After [setting up a Heroku account](https://devcenter.heroku.com/articles/getting-started-with-python), we’re nearly ready to deploy. Let’s walk through the steps.
### **Create a new Heroku app**
Using the Heroku CLI, we log in and create a new app.
```bash
$ heroku login
$ heroku create my-langchain-app
```
### **Set config variables**
Next, we need to set the `OPENAI_API_KEY` environment variable in our Heroku app environment.
```bash
$ heroku config:set OPENAI_API_KEY=replace-with-your-openai-api-key
```
### **Create config files for Python application deployment**
To let Heroku know what we need for our Python application to run, we need to create three simple files:
1. [`Procfile`](https://devcenter.heroku.com/articles/getting-started-with-python#define-a-procfile): Declares what command Heroku should execute to start our app.
2. [`requirements.txt`](https://devcenter.heroku.com/articles/python-pip#the-basics): Specifies the Python package dependencies that Heroku will need to install.
3. [`runtime.txt`](https://devcenter.heroku.com/articles/python-runtimes): Specifies the exact version of the Python runtime we want to use for our app.
These files are quick and easy to create. Each one goes into the project’s root folder. To create the `Procfile`, we run this command:
```bash
$ echo 'web: uvicorn main:app --host=0.0.0.0 --port=${PORT}' > Procfile
```
This tells Heroku to run [`uvicorn`](https://www.uvicorn.org/), which is a web server implementation in Python.
For `requirements.txt`, we can use the [`pip freeze`](https://pip.pypa.io/en/stable/cli/pip_freeze/) command to output the list of installed packages.
```bash
$ pip freeze > requirements.txt
```
Lastly, for `runtime.txt`, we will use Python 3.11.8.
```bash
$ echo 'python-3.11.8' > runtime.txt
```
With these files in place, our project root folder should look like this:
```bash
$ tree
.
├── main.py
├── Procfile
├── requirements.txt
└── runtime.txt
0 directories, 4 files
```
We commit all of these files to the GitHub repository.
### **Connect Heroku to GitHub repo**
The last thing to do is [create a Heroku re](https://devcenter.heroku.com/articles/git)[mote for our GitHub re](https://devcenter.heroku.com/articles/git)po and then push our code to the r[emote. Heroku will det](https://devcenter.heroku.com/articles/git)ect the p[ush of new code and th](https://devcenter.heroku.com/articles/git)en deploy that code to our application.
```bash
$ heroku git:remote -a my-langchain-app
$ git push heroku main
```
When our code is pushed to the Heroku remote, Heroku builds the application, installs dependencies, and then runs the command in our `Procfile`. The final result of our `git push` command looks like this:
```bash
…
remote: -----> Discovering process types
remote: Procfile declares types -> web
remote:
remote: -----> Compressing...
remote: Done: 71.8M
remote: -----> Launching...
remote: Released v4
remote: https://my-langchain-app-ea95419b2750.herokuapp.com/ deployed to Heroku
remote:
remote: Verifying deploy... done.
```
This shows the URL for our Heroku app. In our browser, we visit `https://my-langchain-app-ea95419b2750.herokuapp.com/playground`.
We also check out our Swagger UI docs page at `https://my-langchain-app-ea95419b2750.herokuapp.com/docs`.
And just like that, we’re up and running!
This process is the best way to reduce developer time and overhead when working on large, complex LLM pipelines with LangChain. The ability to take APIs built with LangChain and seamlessly deploy to Heroku with a few simple command line arguments is what makes the pairing of LangChain and Heroku a no-brainer.
## **Conclusion**
Businesses and developers today are right to ride the wave of AI and LLMs. There’s so much room for innovation and new development in these areas. However, the difference between the successes and failures will depend a lot on the toolchain they use to build and deploy these applications.
Using the LangChain framework makes the process of building LLM-based applications approachable and repeatable. But, implementation is only half the battle. Once your application is built, you need the ability to easily and quickly deploy those application APIs into the cloud. That’s where you’ll have the advantage of faster iteration and development, and Heroku is a great way to get you there. | alvinslee |

Students in development and... | 0 | 2024-03-18T16:05:20 | https://code.pieces.app/blog/best-ai-tools-for-students-learning-development-and-engineering | ai, webdev, beginners, programming | Our world is rapidly changing, and AI is a big part of that change. Students in development and engineering (and developers already in their careers) need to become proficient in AI tools. Perhaps not experts, but at least enough to understand how AI might or might not apply to a project.
These best AI tools for students can enhance your learning process and productivity, either in school or on the job. The first section describes each tool, and the second section describes how they could fit together into a streamlined workflow. The third section discusses the factors that affect your choice of AI tools.
## 10 Useful AI Tools for Students (and Developer Advancement)
These ten free AI tools for students are actually free for everyone. They provide a solid foundation to work on a wide range of artificial intelligence (AI) and machine learning projects. By exploring these tools and their documentation, you can gain hands-on experience, develop your skills, and tackle real-world challenges. They are the best AI tools for students and for developers who want to open new job opportunities or [prepare for coding interviews](https://code.pieces.app/blog/code-snippets-coding-interview-prep).
The AI tools used by students, such as toolkits, notebooks, libraries, and frameworks, are the same tools used by developers in their careers. Each of the top AI tools for students plays a different but complementary role in software development. Their meanings sometimes overlap, and the specific roles may vary depending on the context and technology used.
Imagine you are an architect designing houses in a new subdivision. **Frameworks** are the pre-defined models, like a bungalow or a two-story, that provide a basic structure and guide your planning. You use a **notebook** to create your blueprints and sketches, where you experiment and plan the house.
There are two types of components you can use. **Toolkits** provide prefabricated components such as walls, doors, and windows. They speed up construction, but they may limit design freedom. In contrast, **Libraries** provide individual building blocks like bricks, pipes, and electrical components. You can use them independently or combine them into larger components.
Which label applies to a tool sometimes depends on what you do with it. For example, [PyTorch](https://pytorch.org/) or [TensorFlow](https://www.tensorflow.org/) can be called a library, a toolkit, or a machine-learning framework.
1. **Jupyter Notebook:** Jupyter Notebook allows you to create documents called _notebooks_ that combine code, text, and visualizations in a single interface. It supports multiple programming languages, including Python, R, and Julia. Jupyter Notebook is widely used in data analysis and exploration, machine-learning prototyping, and educational settings. It promotes reproducibility by capturing code, its output, and your textual explanations in a single file that can be shared with others.
1. **TensorFlow:** TensorFlow is an open-source machine-learning _framework_ developed by Google. It provides a wide range of tools and libraries for building, training, and [deploying various types of machine learning models](https://code.pieces.app/blog/the-ultimate-guide-to-ml-model-deployment), with a focus on deep learning.

1,794,850 | Take the pain to learn user authentication before you use an external provider | External user authentication is not as simple, secure and cheap as it seems. These are the lessons I... | 0 | 2024-03-19T09:01:37 | https://dev.to/aneesh_arora/take-the-pain-to-learn-user-authentication-before-you-use-an-external-provider-299b | security, webdev | External user authentication is not as simple, secure and cheap as it seems. These are the lessons I learned while implementing user authentication and authorization for my startup [Afterword](https://www.afterword.tech/).
Most startups nowadays rely on external user authentication services called **"Identity as a Service" (IDaaS)** or **"Authentication as a Service" (AuthaaS)**. Even big companies like [OpenAI use auth0](https://twitter.com/kwuchu/status/1641477407180824576). Firebase by Google is also really popular. While I guess it makes sense in the world of “move fast and break things” we have been sold a lot of lies about user authentication by these providers which I would like to dispel.
Developers think outsourcing user authentication to an external provider is easier, more secure, cheaper in the short run but it’s not true. If you don’t understand security well enough you will still store important information like user authentication tokens in localstorage or cookies that can be read by client side javascript. Javascript injection attacks will allow hackers to steal user credentials and pretend to be them, exposing user data and consuming their credits in a Saas application.
## Problems with external user authentication services
- **The False Security of Outsourcing:** Outsourcing user authentication does not automatically ensure security; poor implementation can leave users exposed.
- **Privacy Concerns with Third-Party Data Handling:** Utilizing third-party authentication involves entrusting user login data to another vendor, risking user privacy and data exploitation by competitors.
- **Control Over User Authentication Flow:** Third-party services limit customization and control the flow of user authentication, degrading user experience due to external redirections.
- **Design Constraints with Pre-Designed UI:** Pre-designed user interfaces from third-party services may not align with your site's aesthetics, causing a disjointed experience.
- **Tech Stack Compatibility Issues:** Third-party user authentication may not seamlessly integrate with your specific tech stack.
- **Time Efficiency in Self-Implementation:** Self-implementation of user authentication can be quicker with proper understanding; my experience saw more than a week for third-party setup versus 4-5 days for in-house.
- Cost of Third-Party Authentication
- **Hosted Services:** Costs escalate with user growth.
- **Self-Hosting:** Adds complexity when deploying and contributes to extra costs also.
- **Costs of Advanced Features:** Extra features like social login and multi-factor authentication in external services incur additional expenses.
- **The Risks of Vendor Lock-In:** Dependence on third-party providers exposes you to their changing terms, costs, and risks of vendor lock-in.
- **Challenges in Transitioning to In-House Solutions:** Shifting to an in-house system later can be complex, often necessitating password changes for users, thus increasing friction and dissatisfaction.
## The basics of user authentication and authorization
User authentication and authorization may initially appear challenging and intimidating, but this perception changes once you grasp the underlying mechanisms. Moreover, it's an essential aspect you can't bypass. Despite popular belief, third-party user authentication isn't the panacea it's often made out to be.
In the sections below, I'll guide you through a secure method for implementing user authentication and authorization. While there are other approaches, they fall beyond the scope of this blog post.
First let’s understand the difference between user authentication and user authorization:
1. **User Authentication:** Process of verifying identity of the user. Typically done using username and password.
2. **User Authorization:** Verifying the logged in user when they make a certain request like accessing their saved data or performing any action that the user should be signed in for.
Upon successful user authentication, that is, when they log in, the server issues a cookie containing a token(a unique string). This cookie is sent by the browser with each subsequent request, allowing the server to verify the user's identity and respond to their requests.
There are two primary methods to verify this token:
1. **Database Storage:** Store the token and its corresponding user ID (a unique identifier in the database akin to a primary key) in the database.
2. **JSON Web Token (JWT):** Utilize JWT, a widely supported standard that I will explain below.
## How JSON Web Token works
Many libraries support JWT so you don’t have to implement it yourself but you do need to understand it. One good one for python is **PyJWT.**
`pip install PyJWT`
JWTs are advantageous as they encapsulate user details, such as the user ID, along with other pertinent information chosen by the developer. This data is encrypted using a secret key and stored in the cookie. When the user makes a request, the server decrypts the JWT to identify the user and access their data.
Benefits of using JWT include:
- **Speed:** Eliminates the need for additional database queries to fetch the user ID.
- **Built-in Expiration:** JWTs have an inherent expiry time, enhancing security by limiting the window during which a compromised token could be used.
At Afterword, for instance, access tokens expire after one hour for added user safety.
Example code to create and decode JWT in python using PyJWT:
```
import jwt
from jwt import PyJWTError
from datetime import datetime, timedelta
SECRET_KEY = "Generate a secret key and put it here"
ALGORITHM = "HS256"
TOKEN_EXPIRE_MINUTES = 60
def create_jwt(data: dict):
to_encode = data.copy()
expire = datetime.utcnow() + timedelta(minutes=TOKEN_EXPIRE_MINUTES)
to_encode.update({"exp": expire})
encoded_jwt = jwt.encode(to_encode, SECRET_KEY, algorithm=ALGORITHM)
return encoded_jwt
# Verify JWT token
def decode_token(token):
try:
payload = jwt.decode(token, SECRET_KEY, algorithms=[ALGORITHM])
return payload
except PyJWTError:
raise Exception(status_code=401, detail="Could not validate credentials")
create_jwt({"user_id":user_id}) #you can also put other user data in this dict as key value pairs
```
To address the issue of token expiration and avoid frequent re-logins, which could detract from user experience, we employ a dual-token approach:
- **Access Token:** Short-lived, used for regular authentication.
- **Refresh Token:** Longer-lived, used to request new access tokens.
The refresh token is only sent to the server when an access token is rejected, not with every request. This strategy minimizes the risk of a refresh token being compromised. For heightened security, the refresh token can be stored in the database and validated against it. Upon user logout, or to prevent misuse, refresh tokens can be either deleted or added to a blacklist, ensuring that outdated, yet valid, tokens cannot be used to gain unauthorized access.
## Storing JWTs (access and refresh tokens) browser side
Since **local storage and other storage methods like IndexedDB** can be accessed by javascript running in the browser they are not a safe place to store user authorization credentials. Hackers can exploit it using **Cross-Site Scripting (XSS)** to inject malicious code and access these tokens.
An alternative to this is the use of **cookies**. While regular cookies can be accessed by JavaScript, **HTTP-only** cookies are more secure as they are **accessible only to the server**. The browser is designed to prevent any JavaScript from reading HTTP-only cookies. Moreover, cookies set by the server should be flagged as **'Secure'** to ensure they are transmitted exclusively over **HTTPS** connections, not **unsecured HTTP**.
Another critical attribute of cookies for security is the **'SameSite'** flag. Setting this flag to either **'Strict' or 'Lax'**, instead of **'None'**, significantly enhances security. This configuration helps prevent the browser from sending the user's cookies in response to **Cross-Site Request Forgery (CSRF) attacks**. When combined with the HTTP-only and Secure flags, setting SameSite to 'Strict' provides robust protection by safeguarding against XSS, CSRF, and ensuring that all data is transmitted securely over HTTPS.
For additional layers of security, the implementation of CSRF tokens can be considered.
Example of setting a secure, HTTP-only and SameSite="Strict" using a fastapi server:
```
from fastapi import FastAPI, Response, Form
from typing import Annotated
from fastapi.middleware.cors import CORSMiddleware
app = FastAPI()
# Set up CORS middleware
app.add_middleware(
CORSMiddleware,
allow_origins=[FRONTEND_URL],
allow_credentials=True,
allow_methods=["*"], # Allows all methods
allow_headers=["*"], # Allows all headers
)
TOKEN_EXPIRE_MINUTES = 60
@app.post("/login")
async def login(email: Annotated[str, Form()], password: Annotated[str, Form()], response: Response):
user = #Retrieve user from database using email
if user and password == user["password"]: #Don't store password in plain text in a real application
response.set_cookie("token", value=JWT_token, max_age=TOKEN_EXPIRE_MINUTES*60, httponly=True, secure=True, samesite="Strict", domain="your site domain")
return True
else:
return False
```
This provides a solid foundation in understanding the user authentication and authorization flow, valuable knowledge regardless of whether you opt for an external provider. To develop a fully in-house user authentication and authorization system, more in-depth information is required. Stay tuned for the **second part** of this blog post, where I'll delve into password encryption and the intricacies of sending emails.

1,794,906 | How to Implement Micro Frontends Using SystemJS: A Comprehensive Guide | In the ever-evolving landscape of web development, the need for scalable, maintainable, and flexible... | 0 | 2024-03-19T09:55:10 | https://dev.to/hamed-fatehi/how-to-implement-micro-frontends-using-systemjs-a-comprehensive-guide-i3a | javascript, webdev, programming, react | In the ever-evolving landscape of web development, the need for scalable, maintainable, and flexible architectures has never been greater. Enter micro frontends, a design approach that breaks down the frontend monolith into smaller, more manageable pieces. Much like microservices have revolutionized backend development by decomposing complex applications into smaller services, micro frontends aim to achieve the same for the user interface. The benefits of this approach are manifold:
- **Scalability**: By breaking down the frontend into smaller units, teams can scale development processes more efficiently.
- **Independence**: Different teams can work on different parts of the frontend simultaneously without stepping on each other's toes.
- **Flexibility**: It's easier to experiment with new technologies or frameworks when you're working with a smaller piece of the puzzle.
- **Resilience**: A failure in one micro frontend doesn't necessarily bring down the entire application.
- **Reusability**: Components or entire micro frontends can be reused across different parts of the application or even different projects.
Given these advantages, it's tempting to dive right into micro frontends. However, it's crucial to understand the architectural choices available and their implications. Broadly speaking, there are two prevalent approaches:
1.**Central Orchestrator Model**: In this approach, there's a primary application that acts as the orchestrator. It's responsible for mounting and unmounting micro frontends based on user interactions or other triggers. This centralized control can simplify state management and inter-micro frontend communication. However, a significant challenge arises when different micro frontends use different frameworks. Even varying versions of the same framework can pose integration challenges. Consistency in technology choices becomes essential for smooth operation.
2.**Route-Driven Fragmentation**: Here, the main application is stripped down to its bare essentials, primarily handling routes. Each route or link corresponds to a micro frontend, making this approach particularly suitable for dashboards or applications where each view is distinct. The primary advantage is the flexibility it offers. Since each micro frontend is loaded independently based on routes, there's greater freedom in choosing frameworks or technologies for each one. Teams can pick the best tool for the job without being constrained by the choices of other micro frontends.
## State Management in Micro Frontends
State management is a cornerstone of any frontend application, determining how data flows, is stored, and is manipulated. When diving into the realm of micro frontends, the challenge amplifies, given the distributed nature of the architecture. Let's explore how state management varies between the two primary micro frontend architectural approaches.
### Central Orchestrator Model
In this approach, the overarching application acts as the central hub, making it conducive to employ a centralized state management system. Tools like Redux, Vuex, or NgRx can be seamlessly integrated, allowing for a unified store that holds the global state.
- **Programmatic State Passing**: The main application can pass down relevant parts of the state to individual micro frontends as they are mounted. Depending on the framework, this can be achieved through props, context, or other mechanisms. This ensures that each micro frontend has access to the data it needs without being overwhelmed by the entirety of the global state.
- **Modularity with Centralization**: Even though the state is centralized, it doesn't mean everything is lumped together. Middleware, actions, reducers, or equivalent constructs can be organized around individual micro frontends. This ensures modularity and maintainability while benefiting from a unified data store.
### Route-Driven Fragmentation
Given the isolated nature of micro frontends in this approach, state management tends to be more decentralized.
- **URL Params:** State relevant to navigation or user interface settings can be encoded in the URL. This allows for deep linking, where users can bookmark or share specific application views. For instance, a dashboard's filter settings might be represented as URL parameters, ensuring consistent views upon navigation.
- **Global Window Variables:** While not always recommended due to potential risks like accidental overwrites, global window variables can serve as a mechanism to share state or functions between micro frontends. However, care must be taken to ensure encapsulation and avoid naming collisions.
- **External State Stores:** To achieve a shared state without relying on the main app, micro frontends can resort to external state stores or services. Backend APIs, browser databases like IndexedDB, or even cloud-based real-time databases can be employed. This allows micro frontends to fetch and update shared state independently.
In essence, while the "Central Orchestrator Model" approach leans towards a more centralized state management system, the "Route-Driven Fragmentation" approach demands a more decentralized and strategic approach to handle state. Both methods come with their set of challenges and advantages, and the choice largely depends on the specific needs of the application and the preferences of the development team.
## Technical Implementation
In the realm of Micro Frontends, whether you opt for the Central Orchestrator Model or the Route-Driven Fragmentation approach, the technical implementation plays a crucial role. There are several interesting options available, from Import Maps for controlled module loading to leveraging the dynamic module capabilities of SystemJS. Module Federation offers a way to seamlessly share dependencies across builds, while Single SPA provides a comprehensive solution specifically designed for managing Micro Frontends and often suggests using SystemJS for optimal module loading. Each of these options has its own pros and cons.
I conclude this article with an example, demonstrating how to use SystemJS to implement Micro Frontends without additional frameworks. The advantage of SystemJS over Webpack Module Federation is that it does not bind you to a specific bundler.
- **Structure of the Micro Frontend**:
The Micro Frontend defines two functions, `mount` and `unmount` in `src/main.tsx`, which enable the main application to control the loading and unloading of the Micro Frontend.
```typescript
// src/main.tsx
let rootInstance: Root | null = null;
export function mount(containerId: string, token: string) {
const container = document.getElementById(containerId);
if (!container) {
console.error(`Container with id "${containerId}" not found.`);
return;
}
initializeFirebase(token);
rootInstance = createRoot(container);
rootInstance.render(
<ChatPartnerProvider>
<App />
</ChatPartnerProvider>
);
}
export function unmount(containerId: string) {
if (rootInstance) {
rootInstance.unmount();
rootInstance = null;
} else {
console.error(`Application not mounted to "${containerId}"`);
}
}
```
- **Dynamic Loading through the Main Application**:
The main application uses SystemJS to dynamically load the Micro Frontend. The `loadMicroFrontend` function loads the bundled Micro Frontend from a Google Cloud Storage Bucket.
```typescript
let microFrontendPromise: Promise<any> | null = null;
export type MicroFe = {
mount: (containerId: string) => void,
unmount: (containerId: string) => void,
};
export const loadMicroFrontend = async (): Promise<MicroFe | undefined> => {
if (!microFrontendPromise) {
microFrontendPromise = System.import("https://some-bucket.com/chat-micro-fe/main-chat-fe.js")
.then((module) => {
return { ...module };
})
.catch((err) => {
microFrontendPromise = null;
throw err;
});
}
return microFrontendPromise;
};
```
- **Integration and Control by the Main Application**:
The `MicroFrontend` component in the main application uses `useEffect` to mount the Micro Frontend upon loading and to unmount it upon removal.
```typescript
export default function MicroFrontend({ containerId }: MicroFrontendProps) {
useEffect(() => {
let microFe: MicroFe | undefined;
const loader = async () => {
microFe = await loadMicroFrontend();
microFe && microFe.mount(containerId);
};
loader();
return () => microFe && microFe.unmount(containerId);
}, [containerId]);
return <div id={containerId} />;
}
```
- **Handling Shared Dependencies**:
The main application's HTML document provides shared dependencies through a `systemjs-importmap`.
```html
<!DOCTYPE html>
<html lang="en">
<head>
<script type="systemjs-importmap">
{
"imports": {
"react": "/react.development.js",
"react-dom": "/react-dom.development.js",
"@mui/material": "/material-ui.production.min.js"
}
}
</script>
</head>
<body>
...
</body>
</html>
```
As always, I'm grateful for any feedback.
Cheers,
Hamed

parameters={
"model": "gpt-4-turbo-preview",
"temperature": 0.2,
"max_tokens": 1500,
},
)
```
**Defining Agents and Tasks**
We define two agents:
**Senior Research Analyst**: This agent conducts a comprehensive analysis of the subject provided by the user. The agent’s task is to generate an eye-catching blog title with bold and bigger font.
```
researcher = Agent(
role='Senior Research Analyst',
prompt_persona=f'You are an Expert SENIOR RESEARCH ANALYST. Your task is to CONDUCT a comprehensive analysis on a given {subject}.'
)
task1 = Task(
name="Subject Analysis",

)
```
**Running the Pipeline**
Once the user enters the subject, our pipeline kicks in. It consists of two tasks:
**1. Subject Analysis:** The Senior Research Analyst analyzes the subject and generates an attention-grabbing blog title.
**2. Write Blog Content:** The Digital Content Creator generates a comprehensive guide for blogging. The guide covers essential elements such as selecting a niche, understanding the audience, setting up a blog, implementing SEO strategies, monetization methods, promoting the blog, and maintaining consistency.
```
output = LinearSyncPipeline(
name="Blog Generator",
completion_message="pipeline completed",
tasks=[task1,task2],
).run()
```
```
print(output[0]['task_output'])
```
With the completion of the pipeline, our blog generator produces a well-structured and informative blog post tailored to the user’s subject. By automating the content generation process, we save time and effort while ensuring quality output.
Congratulations on embarking on your blogging journey armed with the knowledge and tools provided in this guide.

1,795,196 | Reskilling and Upskilling: Staying Relevant in the Digital Age | As industries evolve and the demand for digital proficiency increases, the concepts of reskilling and... | 26,529 | 2024-03-19T13:32:35 | https://www.covalence.io/post/reskilling-and-upskilling-staying-relevant-in-the-digital-age | coding, webdev, beginners, programming | As industries evolve and the demand for digital proficiency increases, the concepts of reskilling and upskilling have become critical for individuals and organizations to stay relevant and competitive. Technological advancements are reshaping industries at an unprecedented pace, and individuals who are not equipped with up-to-date skills can quickly find themselves left behind. The answer to staying relevant in this digital age? Reskilling and Upskilling.
### What is Reskilling and Upskilling?
[Reskilling](https://learning.linkedin.com/resources/upskilling-and-reskilling/upskilling-reskilling) refers to the acquisition of new skills or abilities, enabling individuals to perform a different job, while [upskilling](https://learning.linkedin.com/resources/upskilling-and-reskilling/upskilling-reskilling) involves enhancing current skills to perform a job more effectively. Both are facets of continuous learning, an essential component of career development in the digital age.
Continuous learning is the ongoing, voluntary, and self-motivated pursuit of knowledge, which is crucial in the ever-evolving digital world. With the advent of automation, AI, and other technological advances, job roles are being redefined, and new ones are emerging. This dynamic environment necessitates constant learning and adaptation to remain relevant.
### The Importance of Continuous Learning
Gone are the days when education was something confined to a classroom and completed in youth. In the digital age, learning is a lifelong journey. As technology revolutionizes industries, skills that were once in demand might become obsolete within a few years. This reality underscores the significance of continuous learning – the process of acquiring new skills and knowledge throughout one's career.
Continuous learning offers several benefits, such as career resilience, professional growth and employability. Continuous learning ensures that professionals remain relevant and capable of thriving in dynamic environments.
### The Rise of Coding Bootcamps

With a curriculum designed to match the needs of the industry, we can provide hands-on experience and real-world project work, making coding bootcamps a great option for both reskilling and upskilling.
Moreover, Covalence is not just for individuals seeking to break into the tech industry. We are also beneficial for those already in the industry looking to upskill and stay up-to-date with the latest technologies and programming languages. However, the key to successful reskilling or upskilling lies in the willingness to learn and adapt. Whether through a coding bootcamp or any other learning platform, individuals must be proactive in their learning journey.
In a world where industries are transformed by technology, the drive to learn and adapt is more critical than ever. Continuous learning ensures that professionals remain relevant and capable of thriving in dynamic environments. Coding bootcamps, with their immersive and targeted approach, have emerged as a beacon for those seeking to reskill or upskill rapidly in response to changing industry demands.
With Covalence's industry-aligned curriculum and practical approach, we offer an excellent avenue for achieving this goal. Designed to equip individuals with the necessary digital skills to thrive in tech-driven industries, Covalence is here to prepare individuals for success.

Next, break down these long-term goals into smaller, actionable objectives. These objectives could include mastering specific front-end frameworks, gaining expertise in responsive design, becoming proficient in accessibility standards, or obtaining relevant certifications.
### Set Achievable Milestones and Timelines
Once you've defined your career goals and objectives, break them down into achievable milestones. These milestones serve as checkpoints to measure your progress and keep you motivated along the way. Each milestone should be specific, measurable, achievable, relevant, and time-bound [(SMART)](https://corporatefinanceinstitute.com/resources/management/smart-goal/).
For example, if your goal is to become proficient in React.js, your milestones could include:
1. Complete an online course on React fundamentals within the next two months.
2. Build a simple React project and deploy it to a hosting platform like [netlify](https://www.netlify.com/) or [Vercel](https://vercel.com/) within three months.
3. Contribute to an open-source React project or collaborate on a team project within six months.
4. Obtain a React certification or complete an advanced React course within one year.
### Establish a Roadmap for Skill Acquisition and Career Progression
To achieve your goals and milestones, establish a roadmap outlining the steps you need to take to acquire the necessary skills and advance your career in front-end development. Your roadmap should be personalized based on your strengths, weaknesses, and learning style.
Start by identifying the key skills and technologies you need to develop to achieve your career objectives. This may include mastering front-end languages like HTML, CSS, and JavaScript, becoming proficient in popular frameworks like React or Angular, and honing your design and UI/UX skills.
Next, prioritize these skills and technologies based on their importance to your career goals and the demand in the industry. Allocate time for learning, practice, and projects, ensuring a balanced approach to skill acquisition.
Consider leveraging various learning resources such as online courses, tutorials, books, documentation, and hands-on projects to enhance your skills. Engage with online communities, attend workshops, and seek mentorship from experienced developers to gain valuable insights and guidance.
Regularly review and update your roadmap as you progress in your front-end development journey. Be flexible and adaptable to changes in technology and industry trends, and don't hesitate to pivot or adjust your goals and objectives as needed.

1,795,236 | 3 Tips to Make Your Next.js App More Stable | Since Next.js introduced the App Router feature, it provides React Server Components (RSC). RSC... | 0 | 2024-03-19T14:22:50 | https://dev.to/suhaotian/3-tips-to-make-your-nextjs-app-more-stable-h57 | nextjs, axios, react, xior |
Since Next.js introduced the `App Router` feature, it provides `React Server Components` (`RSC`).
`RSC` allows your app to render on the server-side, returning static HTML to the browser for faster initial load times.
Here's an example: **Creating a page to render data from an API**
```ts
// app/page.tsx
export default async function HelloPage() {
const data = await fetch('http://127.0.0.1:3068/messages', {cache: 'no-cache'}).then((res) =>
res.json()
);
return <div>{JSON.stringify(data)}</div>
}
```
> **Note**: `{cache: 'no-cache'}` is added to disable caching for testing purposes.
The concern here is: what happens if the API fetch encounters an error? This could lead to a crashed page.
The example code using Express.js to simulate an API:
```ts
import express from 'express';
const app = express();
app.use(express.urlencoded({ extended: true }));
app.use(express.json());
app.get('/', (req, res) => {
res.send('hi');
});
app.get('/messages', (req, res) => {
const isEven = Math.round(Math.random() * 19) % 2 === 0;
if (isEven) {
res.send([
{ id: 1, text: 'Foobar' },
{ id: 1, text: 'Some content' },
]);
} else {
res.status(500).send({
msg: 'some error happend',
});
}
});
app.listen(3068, () => {
console.log(`Server listening at: http://127.0.0.1:3068`);
});
```
Here's how we can improve this scenario:
1. **Implement Error Retries:** If the API call fails, we can retry the request a few times before giving up.
2. **Cache Data:** When the API request is successful, cache the data. If retries still fail, use the cached data to prevent a completely broken page.
3. **Dedupe Requests:** Avoid making unnecessary redundant requests. This prevents multiple identical requests from being sent simultaneously on the fly.
These functionalities can be achieved using libraries like `axios` with its third-party plugins or a library specifically designed for these purposes, such as [`xior`](https://npmjs.org/xior).
In this case, we'll use [`xior`](https://npmjs.org/xior). **xior** offers a similar API to `axios` and leverages the built-in `fetch` API.
**Install `xior`**:
```sh
npm install xior
# or pnpm install
pnpm install xior
```
Create an `app/http.ts` file to configure **xior** with its built-in plugins:
```ts
// app/http.ts
import xior from 'xior';
import errorRetryPlugin from 'xior/plugins/error-retry';
import errorCachePlugin from 'xior/plugins/error-cache';
import dedupeRequestPlugin from 'xior/plugins/dedupe';
export const http = xior.create({
baseURL: 'http://127.0.0.1:3068/',
});
http.plugins.use(
errorRetryPlugin({
retryTimes: 2,
retryInterval(count) {
return count * 250;
},
onRetry(config, error, count) {
console.log(`${config?.method} ${config?.url} retry ${count}`);
},
})
);
http.plugins.use(errorCachePlugin());
if (typeof window !== 'undefined') {
// fetch in Next.js server components, the requests already dedupe
http.plugins.use(dedupeRequestPlugin());
}
```
Create a new page `app/improved/page.tsx` that utilizes the `http.ts` instance:
```tsx
// app/improved/page.tsx
import { http } from '../http';
export default async function ImprovedHelloPage() {
const { data, fromCache, error } = await http.get('/messages', { cache: 'no-cache' });
return (
<div>
{fromCache ? (
<>
<div className="p-2 text-yellow-600 bg-yellow-300">
The data from cache, error: {error?.message}
</div>
<hr />
</>
) : null}
<pre>{JSON.stringify(data, null, 2)}</pre>
</div>
);
}
```
Even if the API call fails and retries are unsuccessful, the page won't crash. Instead, you can show an error message and possibly display cached data or a fallback message. This ensures a better user experience and avoids showing a broken page.

1,795,502 | YAML Based VM Configuration With Cloud-init | Cloud-init is a Canonical project and describes itself as follows: " Cloud -init is the... | 0 | 2024-03-19T18:37:05 | https://dev.to/talhakhalid101/yaml-based-vm-configuration-with-cloud-init-dd3 | tutorial, devops, cloud, cloudcomputing | Cloud-init is a Canonical project and describes itself as follows: " Cloud -init is the industry-standard multi-distribution method for the cross-platform initialization of cloud instances."
To put it more simply: Cloud-init enables the complete configuration of virtual machines (VMs) using a simple text file. Of course, cloud instances mean nothing other than VMs that run on cloud providers such as AWS, Azure or GCC. Basically only with one special feature, namely that the VMs are often fleeting (ephemeral), i.e. they only run for a short time and are then deleted again.
Initialization, in turn, simply means the configuration, i.e. everything apart from the hardware equipment: network connections, settings, installed software, user profiles and so on. And "multi-distribution" probably means nothing other than the fact that you can have several identically configured VMs created at the same time.
Cross-platform means pretty much all major cloud providers are supported; In addition to those already mentioned, Oracle, UpCloud, VMware, OpenNebula, among others, around 25 in total. And there are hardly any restrictions regarding the supported operating systems for the VMs; 26 distributions are listed, in addition to obvious ones such as Debian, Ubuntu , RHEL, Arch Linux and Fedora, also openEuler, Rocky, Virtuozzo and the common BSD systems.
Cloud-init explained in a very rudimentary way: "Dear IT department, we need several VMs with SSH access through Server X, Apache web server, mounted network drives, software packages according to the attached list, the user foobar and a RHEL registration." Cloud-init is nothing more than such a request - just formalized and sent to a supported system.
### Cloud-init in Practice
The easiest way to play with cloud-init is probably Multipass , also a Canonical project and already presented here some time ago . With Multipass, "cloud instances" can be created locally, i.e. VMs, which can optionally be set up using cloud-init. This works on Windows as well as Linux.
By default, Multipass creates VMs with Ubuntu 22.04, hardware equipment and network connection are simply specified via options:
```
multipass launch --mem=2G --cpus=2 --name testvm1 --network name=LAN-Connection
```
So here an Ubuntu VM is created with 2 GB RAM, 2 CPUs and the (Windows) standard network connection "LAN connection".
If a configuration is to be carried out via cloud-config, the config file is also passed to "multipass launch":
```
multipass launch --mem=2G --cpus=2 --name testvm1 --network name=LAN-Connection -- cloud-init testconf.ini
```
All cloud-init work takes place in this "testconf.ini" - a YAML file. YAML is a language based on XML for the machine-readable representation of data structures.
This representation can sometimes be a bit fiddly: be sure to ensure correct indentation. Although it usually doesn't matter whether items are indented with two, four or even three spaces, it must be consistent across the entire document - indentation is part of the YAML syntax! Too many or too few spaces immediately lead to errors.
Cloud-config offers around 60 modules that manage general things like users, but also more specific aspects like the text-based window manager Byobu. A simple version could, for example, simply execute a command in the newly created Multipass VM:
```
#cloud-config
runcmd:
- echo „Hello World!"
- echo „End"
```
The shebang line is required. The module "runcmd" (run command) is then called, which simply executes the following commands.
Here is a practical example that should do the following tasks:
- Output "Hello, World!"
- Install the git and apache2 packages
- Set up standard user ("ubuntu") and user "peter".
- Enable passwordless access from the server "myserver" for user "talha".
- Mount a network drive (Samba share) "myserver/myshare".
- Write a message to the installation log
Formulated via YAML:
```
#cloud-config
runcmd:
- echo 'Hello, World!'
packages:
- git
- apache2
users:
- default
- peter
ssh_authorized_keys:
- ssh-rsa AAAAB3... talha@myserver
mounts:
- [ //192.168.178.1/myshare, /media/myshare, cifs, "defaults,uid=1000,username=talha,password=34565234687gyft@" ]
final_message: |
cloud-init done
Version: $version
Timestamp: $timestamp
Datasource: $datasource
Uptime: $uptime
```
The "packages" module is only used here to install packages, but can also update using the "package_update" and "package_upgrade" calls.
At this point the platform independence is also nice to see. In earlier versions it was called "apt_update", but now the appropriate package manager is targeted. Separate modules are then available for configuring the package managers, e.g. apt, yum/dnf or zypper.
Of course, the "users" module also has a lot more to offer. The full range of account settings can be used here, such as group memberships, user information, passwords, home directories, specific user shell, sudo membership, etc.
But the module "ssh_authorized_keys:" is really interesting. Here it is possible to store the contents of public SSH keys (admittedly in an abbreviated form above) in order to immediately grant password-free access for certain users. This would be practical, for example, for automatic configuration via Ansible , which by default connects to the hosts to be managed via SSH.
The "mounts" module also does exactly what is expected: it writes entries into the fstab - only the separation via comma differs from manual entries.
These examples clearly show what cloud-init essentially does: execute standard commands. Only, for example, it says abstractly "packages: apache2" instead of system-specifically "apt install apache2". You could say that cloud-init is ultimately "just" an abstraction layer for what admins otherwise do manually in the first half hour after setting up a VM… or even on the first day.
### More Functions
If you’re interested, it’s best to look through the individual modules yourself; the [Cloud-init module reference](https://cloudinit.readthedocs.io/en/latest/reference/modules.htm) is very clear and, fortunately, mostly enriched with practical examples. To illustrate the diversity, here are a few highlights.
Using the Ansible module, playbooks can be executed via ansible pull — even without SSH access. There is a module “Byobu” that can be used to configure the window manager mentioned above — very special. The “Phone Home” module is powerful and can be used to send data to a URL.
Similarly powerful is “Scripts per Boot”, which, as expected, executes any script when an instance starts — every time, mind you! Most modules run once per instance, i.e. once during setup. Optionally, they can also be active (“Always”) at every start. For example, “Phone Home” could be used to send data to an API after every start .
Last but not least: [Cloud-init also has a command line interface](https://cloudinit.readthedocs.io/en/latest/reference/cli.html) , for example to run individual modules, check cloud-config files, analyze logs and so on.
Cloud-init is a wonderful tool for understanding and implementing “Infrastructure as Code”. And not just on a large scale, by the way, the combination of cloud-init plus Multipass is unbeatable even for local test environments on the desktop.

1,795,517 | Como os Sui Primitives Revolucionam os Jogos Onchain | Os poderosos Sui primitives elevam as experiências de jogos onchain! Do zkLogin aos Blocos de... | 0 | 2024-03-19T19:16:17 | https://dev.to/sui_brasil/como-os-sui-primitives-revolucionam-os-jogos-onchain-3p86 | webdev, blockchain, gamedev | Os poderosos Sui primitives elevam as experiências de jogos onchain!
Do zkLogin aos Blocos de Transações Programáveis (PTB - Programmable Transaction Blocks), os Sui primitives oferecem aos desenvolvedores de jogos as ferramentas para finalmente aproveitar o poder da Web3, proporcionando aos jogadores novas experiências e engajamentos nos jogos que amam. Blockchains anteriores eram tecnicamente limitados em como poderiam suportar jogos onchain, mas a Sui oferece o desempenho e a eficiência de que os desenvolvedores precisam.
E o momento não poderia ser mais propício, já que as tendências da indústria apontam para um momento de jogos onchain em 2024. Um relatório da Delphi Digital cita uma nova onda de investimento e interesse, incentivando estúdios a explorar mais profundamente como a Web3 e a tecnologia blockchain atendem às demandas dos jogadores.
Embora o Sui primitives sirvam a uma variedade de casos de uso, incluindo DeFi e ativos do mundo real, eles terão um impacto profundo nos jogos onchain. Sua combinação sinérgica mostra uma capacidade coletiva de melhorar o engajamento e a experiência do usuário dentro do ecossistema de jogos da Sui.
### zkLogin: Simplificando o onboarding para jogadores
Na vanguarda da melhoria da acessibilidade do usuário está o zkLogin, uma solução revolucionária que aborda os desafios de onboarding enfrentados por novos jogadores aventurando-se em jogos baseados em blockchain. O processo oneroso de criar e gerenciar novas contas blockchain muitas vezes afasta potenciais usuários. No entanto, o zkLogin simplifica esse processo, permitindo que os jogadores se autentiquem de forma segura e realizem transações usando suas credenciais existentes de Web2.
Essa integração contínua com credenciais de login da Web2 não apenas simplifica o onboarding, mas também promove um ambiente mais inclusivo, atendendo a jogadores com diferentes níveis de conhecimento em blockchain. Ao abstrair as interações com blockchain dos usuários, o zkLogin melhora significativamente a acessibilidade e usabilidade dos jogos onchain dentro do ecossistema Sui.
### Sponsored Transactions: Eliminando o atrito das taxas de gás
O Sui aborda o ônus das taxas de gás blockchain por meio de transações patrocinadas (sponsored transactions), um primitivo que alivia uma barreira comum de onboarding para novos usuários. Tradicionalmente, exigir que os usuários paguem taxas na moeda nativa do blockchain subjacente representa uma barreira significativa à entrada para aplicativos. No entanto, transações patrocinadas capacitam desenvolvedores de jogos a subsidiar transações específicas de usuários, abstraindo as taxas de gás da experiência do usuário final.
Essa abordagem inovadora não apenas reduz o atrito de onboarding, mas também fornece aos desenvolvedores controle granular sobre a subsidiação de taxas de gás. Em vez de fazer com que os usuários paguem taxas de gás à medida que jogam, os desenvolvedores podem habilitar modelos de receita comprovados, como suporte por anúncios, assinaturas e freemium.
### Blocos de Transações Programáveis: Simplificando interações
Os Blocos de Transações Programáveis (PTBs) simplificam drasticamente as interações com blockchain para jogadores e desenvolvedores. Ao permitir a agrupação, assinatura e submissão de transações complexas em um processo unificado, os PTBs simplificam interações dentro de jogos onchain. Essa execução contínua de múltiplas transações em um único bloco melhora a experiência do usuário, garantindo processos coesos e atômicos, mitigando o risco de falhas de transação no meio de uma série de interações desejadas.
Os PTBs empoderam desenvolvedores de jogos a criar experiências de jogo envolvendo múltiplos aplicativos e interações dentro de um único bloco de transação, requerendo uma única interação do usuário. Isso promove um ambiente de jogo mais imersivo e contínuo no Sui.
### Sui Kiosk: Empoderando o controle de ativos em jogos
O Sui Kiosk permite que os jogadores mantenham controle total sobre seus ativos no jogo, mesmo quando listados para venda. Em ambientes de jogos tradicionais, os usuários frequentemente renunciam às habilidades relacionadas à propriedade ao negociar ativos. No entanto, o Sui Kiosk facilita a transferência de propriedade de ativos enquanto permite que os criadores definam políticas específicas para a negociação de ativos.
Para desenvolvedores, o Sui Kiosk pode alimentar uma loja no jogo onde os personagens compram equipamentos, ou um sistema de negociação em nível de ecossistema onde os jogadores compram e vendem itens que encontram no jogo. Os desenvolvedores podem definir as funcionalidades de negociação e até determinar como os itens funcionam fora do jogo. Eliminando a necessidade de camadas adicionais ou serviços de terceiros, a Sui Kiosk simplifica a negociação de ativos dentro de jogos onchain no Sui.
### Desbloqueando o potencial dos jogos onchain na Sui
Os primitivos inovadores da Sui estão prontos para revolucionar a paisagem dos jogos onchain, oferecendo experiências de usuário sem paralelo e fomentando um ecossistema de jogos vibrante. Desde simplificar o onboarding com zkLogin até eliminar o atrito das taxas de gás através de transações patrocinadas, a Sui proporciona um ambiente para desenvolvedores criarem experiências de jogo imersivas e sem fricção. Com os PTBs simplificando interações e o Kiosk empoderando o controle de ativos, a Sui está redefinindo o padrão dos jogos onchain.
Fique atento para melhorias futuras e novos Sui primitives, à medida que a jornada em direção a uma nova era de jogos onchain continua na Sui!

La idea detrás de Mobile First es que, dado que cada vez más personas acceden a internet desde dispositivos móviles, es fundamental diseñar y desarrollar primero para estos dispositivos.
Ventajas de Mobile First:
Mejora la experiencia del usuario: Al diseñar primero para dispositivos móviles, puedes asegurarte de que tu sitio web o aplicación sea fácil de usar en pantallas más pequeñas, lo que mejora la experiencia del usuario.
Mejora el rendimiento: Al optimizar tu sitio web o aplicación para dispositivos móviles, puedes reducir el tiempo de carga y mejorar el rendimiento en general.
Mejora el SEO: Google y otros motores de búsqueda favorecen los sitios web optimizados para dispositivos móviles en sus resultados de búsqueda, lo que puede mejorar tu posicionamiento SEO.
Desktop First: Enfoque tradicional para sitios web
Por otro lado, Desktop First es el enfoque tradicional para el diseño y desarrollo web, que prioriza la experiencia del usuario en computadoras de escritorio. Aunque este enfoque ha sido común durante muchos años, cada vez es menos popular debido al crecimiento del uso de dispositivos móviles.
Ventajas de Desktop First:
Mayor espacio y capacidad: Los dispositivos de escritorio suelen tener pantallas más grandes y más capacidad de procesamiento, lo que permite crear interfaces más complejas y ricas en contenido.
Mejor compatibilidad: Al diseñar primero para computadoras de escritorio, puedes asegurarte de que tu sitio web funcione bien en navegadores más antiguos o menos comunes que pueden no ser compatibles con los estándares móviles más recientes.
¿Cuál es el mejor enfoque?
Aunque ambos enfoques tienen sus ventajas, en la actualidad se considera que Mobile First es el enfoque más efectivo para el diseño y desarrollo web. Dado el creciente número de usuarios que acceden a internet desde dispositivos móviles, priorizar la experiencia del usuario en estos dispositivos puede mejorar significativamente el éxito de tu sitio web o aplicación.
En resumen, Mobile First y Desktop First son dos enfoques diferentes para el diseño y desarrollo web, con Mobile First siendo el más recomendado en la actualidad debido al crecimiento del uso de dispositivos móviles. Al comprender estos conceptos, puedes tomar decisiones informadas sobre cómo desarrollar tu proyecto y ofrecer la mejor experiencia posible a tus usuarios.
