1,909,000 | Using OpenAI Whisper to Transcribe Podcasts on Koyeb | Real-time automated transcription is incredibly useful for anyone who needs to capture spoken content... | 0 | 2024-07-02T13:32:05 | https://www.koyeb.com/tutorials/using-openai-whisper-to-transcribe-podcasts-on-koyeb | tutorial, ai, webdev, python | Real-time automated transcription is incredibly useful for anyone who needs to capture spoken content quickly and accurately. Whether you're creating subtitles for videos, transcribing podcast episodes, or documenting meeting notes, having an automated system can save you a lot of time and effort.
In practical terms, automated transcription can be used in various real-world scenarios. For instance, journalists can transcribe interviews on the fly, educators can provide real-time captions for their lectures, and businesses can document conference calls and meetings more efficiently.
[OpenAI Whisper](https://github.com/openai/whisper) is an open-source solution built for this purpose. It uses state-of-the-art machine learning algorithms to transcribe speech with high accuracy, even handling different accents and speaking speeds.
In this tutorial, you will learn how to set up a [Streamlit](https://streamlit.io/) application, integrate OpenAI Whisper for real-time podcast transcription, and deploy the application using Docker and Koyeb, creating a scalable transcription service.
You can consult the [project repository](https://github.com/koyeb/example-whisper-transcription) as work through this guide. You can deploy the podcast transcription application as built in this tutorial using the [Deploy to Koyeb](https://www.koyeb.com/docs/build-and-deploy/deploy-to-koyeb-button) button below:
[](https://app.koyeb.com/deploy?name=whisper-transcription&type=git&repository=koyeb%2Fexample-whisper-transcription&branch=main&builder=dockerfile&instance_type=gpu-nvidia-rtx-4000-sff-ada&env%5B%5D=&ports=8000%3Bhttp%3B%2F)
## Requirements
To successfully follow this tutorial, you will need the following:
- [Git](https://git-scm.com/) installed
- [FFmpeg](https://ffmpeg.org/) installed
- [Python 3.6+](https://www.python.org/downloads/release/python-360/) or later
- A [Koyeb](https://app.koyeb.com/) account
## Demo
Before we jump into the technical details, let me give you a sneak peek of what you will be building in this tutorial:
{% youtube HlVhwUriUnE %}
## Understanding the components
### OpenAI Whisper
OpenAI Whisper is a sophisticated speech-to-text (STT) model designed to transcribe spoken words into written text with high accuracy. Utilizing advanced machine learning algorithms, Whisper is capable of recognizing various accents, dialects, and speaking speeds. It can be integrated into voice assistants, dictation software, and real-time translation services to convert spoken language into text efficiently.
OpenAI Whisper can be used in sectors such as healthcare for medical dictation, in customer service for automated call transcriptions, and in media for generating subtitles for videos and podcasts. Its ability to handle complex speech patterns and languages makes it the go-to service in any application requiring high-quality speech-to-text conversion.
### Streamlit
Streamlit is an open-source Python library designed to create interactive data applications, often referred to as dashboards. It empowers developers to build and share data apps simply and intuitively, eliminating the need for extensive web development expertise.
Streamlit apps are created as Python scripts, which are then executed within the Streamlit environment. The library offers a set of functions that can be used to add interactive elements to the app such as upload file button.
## Steps
To build the transcription service, we'll complete the following steps:
1. [Set up the environment](#set-up-the-environment): Start by setting up your project directory, installing necessary dependencies, and configuring environment variables.
2. [Set up Streamlit](#set-up-streamlit): Next, install Streamlit and create the initial user interface for your application.
3. [Transcribe podcasts with OpenAI Whisper](#transcribe-podcasts-with-open-ai-whisper): Use OpenAI Whisper to transcribe podcasts into text with timestamps.
4. [Dockerize the Streamlit application](#dockerize-the-streamlit-application): Create a Dockerfile to containerize your application for consistent deployment.
5. [Deploy to Koyeb](#deploy-to-koyeb): Finally, deploy your application on the Koyeb platform.
## Set up the environment
Let's start by creating a new Streamlit project. To keep your Python dependencies organized you should create a virtual environment.
First, create and navigate into a local directory:
```
# Create and move to the new directory
mkdir example-whisper-koyeb-gpu
cd example-whisper-koyeb-gpu
```
Afterwards, create and activate a new virtual environment:
```
# Create a virtual environment
python -m venv venv
# Active the virtual environment (Windows)
.\venv\Scripts\activate.bat
# Active the virtual environment (Linux)
source ./venv/bin/activate
```
Now, you can install the required dependencies. Open a `requirements.txt` file in your project directory with the following contents:
```
streamlit
openai-whisper
watchdog
```
Pass the file to `pip` to install the dependencies:
```
pip install -r requirements.txt
```
For the dependencies, we have included Streamlit for building the web app, OpenAI Whisper for real-time transcription, and watchdog to monitor file system events.
Don't forget to save your dependencies to a `requirements.txt` file:
```
pip freeze > requirements.txt
```
Now, let's move on to creating a new Streamlit project.
## Set up Streamlit
In this step, you will set up the Streamlit UI that will allow users to upload an audio file, click a button to start the transcribing process, and finally present the segmented transcriptions in an user-friendly manner. All of the logic for the project will reside in this file, so you can start by creating a `app.py` file with the following code:
```
# File: app.py
import streamlit
stream_button_styles = """
<style>
header { display: none !important; }
</style>
"""
page_styles = """
<style>
h1 { font-size: 2rem; font-weight: 700; }
h2 { font-size: 1.7rem; font-weight: 600; }
.timestamp { color: gray; font-size: 0.9rem; }
</style>
"""
page_title = "Using OpenAI Whisper to Transcribe Podcasts"
page_description = "A demo showcasing the use of OpenAI Whisper to accurately and efficiently convert spoken content from podcasts into written text."
koyeb_box = "To deploy Whisper within minutes, <a href=\"https://koyeb.com/ai\">Koyeb GPUs</a> provide the easiest and most efficient way. Koyeb offers a seamless platform for deploying AI models, leveraging high-performance GPUs to ensure fast and reliable transcriptions."
step_1 = "1. Upload Podcast"
step_2 = "2. Invoke OpenAI Whisper to transcribe podcast 👇🏻"
step_3 = "3. Transcription 🎉"
def unsafe_html(tag, text):
return streamlit.markdown(f"<{tag}>{text}</{tag}>", unsafe_allow_html=True)
def main():
# Set title for the page
streamlit.set_page_config(page_title, layout="centered")
# Inject hide buttons CSS
streamlit.markdown(stream_button_styles, unsafe_allow_html=True)
# Inject page CSS
streamlit.markdown(page_styles, unsafe_allow_html=True)
# Create a H1 heading on the page
streamlit.title(page_title)
unsafe_html("h2", page_description)
unsafe_html("p", koyeb_box)
audio_file = streamlit.file_uploader(step_1, type=["mp3", "mp4", "wav", "m4a"])
if audio_file:
# If file is received
# Write the file on the server
# Show next step
unsafe_html("small", step_2)
if streamlit.button("Transcribe"):
# Get the transcription
unsafe_html("small", step_3)
# Showcase the transcription
if __name__ == "__main__":
main()
```
The code above does the following:
- Begins by importing the Streamlit module
- Defines CSS for hiding the navigation bar and styling the headings
- Defines text values for the page's title, description, and each step
- Defines the `unsafe_html` function to dynamically create the HTML tags with content
- Accepts an audio file using Streamlit's builtin `file_uploader` function
With this, you have setup a UI that is able to accept podcast audio files from the user. Now, let's move on to transcribing the audio file obtained.
## Transcribe podcasts with OpenAI Whisper
In this step, you will invoke OpenAI Whisper's base model to transcribe an audio file. By default, the model is able to return the timestamps along with the transcription. This enables you to use the generated transcriptions as subtitles as well. Make the following additions in the `app.py` file:
```
# File: app.py
# Existing imports
# . . .
import whisper # [!code ++]
model = whisper.load_model("base") # [!code ++]
# ...
def unsafe_html(tag, text):
# ...
# Generate transcription of each segment
def timestamp_html(segment): # [!code ++]
return f'<span class="timestamp">[{segment["start"]:.2f} - {segment["end"]:.2f}]</span> {segment["text"]}' # [!code ++]
# Transcribe an audio file
def transcribe_audio(audio_file): # [!code ++]
return model.transcribe(audio_file.name) # [!code ++]
# Write the audio file on server
def write_audio(audio_file): # [!code ++]
with open(audio_file.name, "wb") as f: # [!code ++]
f.write(audio_file.read()) # [!code ++]
def main():
# ...
if audio_file:
# If file is received
# Write the file on the server
write_audio(audio_file) # [!code ++]
# Show next step
unsafe_html("small", step_2)
if streamlit.button("Transcribe"):
# Get the transcription
transcript_text = transcribe_audio(audio_file) # [!code ++]
unsafe_html("small", step_3)
# Showcase the transcription
for segment in transcript_text["segments"]: # [!code ++]
unsafe_html("div", timestamp_html(segment)) # [!code ++]
if __name__ == "__main__":
main()
```
The changes above do the following:
- Import and instantiate the OpenAI Whisper base model
- Define a `timestamp_html` function to display the transcription with **start** and **end** timestamps
- Define a `transcribe_audio` function which invokes the model to generate transcriptions of the audio file
- Define a `write_audio` function to write the audio file on the server
- If an audio file is found, it writes the file on the server
- If the **Transcribe** button is clicked in the UI, `transcribe_audio` and `timestamp_html` functions are invoked to generate and display the transcriptions of the podcast
Now, you can run the Streamlit application with:
```
streamlit run ./app.py --server.port 8000
```
The application would now be ready on `http://localhost:8000`. Test the application in action by uploading one of your favorite podcasts file and see the transcriptions generated in real-time.
Next, let's dockerize the application to ensure consistency between multiple deployments.
## Dockerize the Streamlit application
Dockerizing deployments creates a consistent and reproducible environment, ensuring that the application runs the same way on any system. It simplifies dependency management and enhances scalability, making deployments more efficient and reliable. To dockerize, create a `Dockerfile` at the root of your project with the following content:
```
FROM python:3.9 AS builder
WORKDIR /app
RUN python3 -m venv venv
ENV VIRTUAL_ENV=/app/venv
ENV PATH="$VIRTUAL_ENV/bin:$PATH"
COPY requirements.txt .
RUN pip install -r requirements.txt
FROM python:3.9 AS runner
WORKDIR /app
RUN apt-get update && apt-get install -y ffmpeg && rm -rf /var/lib/apt/lists/*
COPY --from=builder /app/venv venv
COPY app.py app.py
ENV VIRTUAL_ENV=/app/venv
ENV PATH="$VIRTUAL_ENV/bin:$PATH"
EXPOSE 8000
CMD ["streamlit", "run", "./app.py", "--server.port", "8000"]
```
Apart from the usual Dockerfile to deploy Python applications, the following tweaks and additions have been made in this code:
- `RUN apt-get update && apt-get install -y ffmpeg && rm -rf /var/lib/apt/lists/*` is used to install `ffmpeg`, and then clean up package lists to reduce image size
- `EXPOSE 8000` is used to specify the port on which the Streamlit application will run
- `CMD ["streamlit", "run", "./app.py", "--server.port", "8000"]` is used to define the command to start the Streamlit app on port 8000
With everything configured, let's move on to deploy the application to Koyeb.
## Deploy to Koyeb
Now that you have the application running locally you can also deploy it on Koyeb and make it available on the internet.
Create a [new repository on your GitHub account](https://github.com/new) so that you can push your code.
You can download a [standard `.gitignore` file](https://raw.githubusercontent.com/github/gitignore/main/Python.gitignore) for Python from GitHub to exclude certain directories and files from being pushed to the repository:
```
curl -L https://raw.githubusercontent.com/github/gitignore/main/Python.gitignore -o .gitignore
```
Run the following commands in your terminal to commit and push your code to the repository:
```
git init
git add app.py Dockerfile requirements.txt .gitignore
git commit -m "first commit"
git branch -M main
git remote add origin [Your GitHub repository URL]
git push -u origin main
```
You should now have all of your local code in your remote repository. Now it is time to deploy the application.
Within the [Koyeb control panel](https://app.koyeb.com/), while on the Overview tab, initiate the app creation and deployment process by clicking **Create Service** and then choosing **Create web service**.
1. Select **GitHub** as the deployment source.
2. Select your repository from the menu. Alternatively, deploy from the [example repository associated with this tutorial](https://github.com/koyeb/example-whisper-transcription) by entering `https://github.com/koyeb/example-whisper-transcription` in the public repository field.
3. In the **Instance** selection, select a GPU Instance.
4. In the **Builder** section, choose **Dockerfile**.
5. Finally, click the **Deploy** button.
Once the application is deployed, you can visit the Koyeb service URL (ending in `.koyeb.app`) to access the Streamlit application.
## Conclusion
In this tutorial, you built a podcast transcription application with the Streamlit framework and OpenAI Whisper. During the process, you learned how to invoke the OpenAI Whisper model in Python to generate transcription with timestamps, and how to use the Streamlit framework to quickly prototype a user interface with a functioning upload button in a few lines of code.
Given that the application was deployed using the Git deployment option, subsequent code push to the deployed branch will automatically initiate a new build for your application. Changes to your application will become live once the deployment is successful. In the event of a failed deployment, Koyeb retains the most recent operational production deployment, ensuring the uninterrupted operation of your application.

1,908,240 | 🚀Supercharged SLIM models Multistep RAG analysis that never leaves your CPU🧑💻 | Many of us are used to models running in the cloud, sending API calls to far-away servers, filed away... | 0 | 2024-07-02T13:30:11 | https://dev.to/simon_risman_1991f73692bc/supercharged-slim-models-multistep-rag-analysis-that-never-leaves-your-cpu-26j0 | Many of us are used to models running in the cloud, sending API calls to far-away servers, filed away as training data for the next wave of GPTs. And how else would this even work? Surely an individual laptop just doesn't have the power to manage and execute the workflows that a cloud based service does.
Consider, for a moment, the mighty ant. At first glance, it may seem insignificant—a mere speck in the grand tapestry of nature. Yet, beneath its tiny exterior lies a powerhouse of strength, resilience, and ingenuity.
<img width="100%" style="width:100%" src="https://i.giphy.com/media/v1.Y2lkPTc5MGI3NjExaW1xM2hjeWRpb3MzZDVrNmFyMmZwNW82dGFxcHoxcnVoank1b3UzZiZlcD12MV9pbnRlcm5hbF9naWZfYnlfaWQmY3Q9Zw/26BRsfBU7ct4jgaCQ/giphy.gif">
##Enter **SLIM** - **S**tructured **L**anguage **I**nstruction **M**odels.🏋️ ##
These models are tiny and run comfortably on a CPU, but pack a punch when it comes to providing specialized, structured outputs. Instead of an AI summary being more bullet points or god forbid paragraphs, SLIM models output a variety of structured data like CSVs, JSONs, and SQL.
The highly specialized nature of the SLIM models is precisely what makes them so powerful - instead of a general solution to a large problem, stringing together a few SLIM models yields more robust performance with greater flexibility.
To show just how much these models can do, we are going to take a look at a tech tale worthy of invoking Gavin Belson: The partnership-turned-rivalry between Microsoft and IBM.
🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜🐜
##0️⃣ Setup 🛠️##
Make sure you have installed llmware and imported the libraries we are going to use. The code below should get you all set up.
Run this command in your terminal
```
pip install llmware
```
Add these imports to the top of your code.
```python
import os
import shutil
from llmware.agents import LLMfx
from llmware.library import Library
from llmware.retrieval import Query
from llmware.configs import LLMWareConfig
from llmware.setup import Setup
```
##1️⃣ Build a Knowledge Base of Microsoft Documents 📖##
First we need to create a database to query. In your case it can be anything from customer service reports to earnings calls, but for now we will use a range of Microsoft-related documents.
```python
def multistep_analysis():
""" In this example, our objective is to research Microsoft history and rivalry in the 1980s with IBM. """
# step 1 - assemble source documents and create library
print("update: Starting example - agent-multistep-analysis")
# note: the program attempts to automatically pull sample document into local path
# depending upon permissions in your environment, you may need to set up directly
# if you pull down the samples files with Setup().load_sample_files(), in the Books folder,
# you will find the source: "Bill-Gates-Biography.pdf"
# if you have pulled sample documents in the past, then to update to latest: set over_write=True
print("update: Loading sample files")
sample_files_path = Setup().load_sample_files(over_write=False)
bill_gates_bio = "Bill-Gates-Biography.pdf"
path_to_bill_gates_bio = os.path.join(sample_files_path, "Books", bill_gates_bio)
microsoft_folder = os.path.join(LLMWareConfig().get_tmp_path(), "example_microsoft")
print("update: attempting to create source input folder at path: ", microsoft_folder)
if not os.path.exists(microsoft_folder):
os.mkdir(microsoft_folder)
os.chmod(microsoft_folder, 0o777)
shutil.copy(path_to_bill_gates_bio,os.path.join(microsoft_folder, bill_gates_bio))
# create library
print("update: creating library and parsing source document")
LLMWareConfig().set_active_db("sqlite")
my_lib = Library().create_new_library("microsoft_history_0210_1")
my_lib.add_files(microsoft_folder)
```
##2️⃣ Locate Mentions of IBM and Create an Agent to Process Them 🔍##
In our first pass we focus on any mention of IBM, and since we have a multistep process we can analyse these instances on a more granular level.
```python
query = "ibm"
search_results = Query(my_lib).text_query(query)
print(f"update: executing query to filter to key passages - {query} - results found - {len(search_results)}")
# create an agent and load several tools that we will be using
agent = LLMfx()
agent.load_tool_list(["sentiment", "emotions", "topic", "tags", "ner", "answer"])
# load the search results into the agent's work queue
agent.load_work(search_results)
```
##3️⃣ Pick out Negative Sentiment 🫳##
This is where you get to decide the depth of your analysis for each item. For our scenario, we want only mentions of IBM that carry negative sentiment (evidence of the rivalry.)
```python
while True:
agent.sentiment()
if not agent.increment_work_iteration():
break
# analyze sections where the sentiment on ibm was negative
follow_up_list = agent.follow_up_list(key="sentiment", value="negative")
```
##4️⃣ Deep Dive Analysis 🤿##
Now that we have picked out the instances we want to explore further, we arm our agent with tools - each tool is a SLIM model built to perform at the highest level on each individual task, providing a comprehensive overview of the pertinent results.
```python
for job_index in follow_up_list:
# follow-up 'deep dive' on selected text that references ibm negatively
agent.set_work_iteration(job_index)
agent.exec_multitool_function_call(["tags", "emotions", "topics", "ner"])
agent.answer("What is a brief summary?", key="summary")
my_report = agent.show_report(follow_up_list)
activity_summary = agent.activity_summary()
for entries in my_report:
print("my report entries: ", entries)
return my_report
```
##Results 🎉🎉🎉##
Your multi-step local RAG model should return a filled out dictionary that looks something like this:
```
report 1 entries: {'sentiment': ['negative'], 'tags': '["IBM", "COBOL", "PL/1", "BAL", "OS/2", "Presentation Manager", "K.", "OS/2 1.0", "December 1987", "1.0"]', 'emotions': ['anger'], 'topics': ['ibm'], 'people': [], 'organization': ['IBM'], 'misc': ['OS/2', 'Presentation Manager'], 'summary': ['•IBM wrote "clunky" code that was top-heavy with lines of documentation to make the software "easy to service."\t\t•IBM wrote "clunky" code that was top-heavy with lines of documentation to make the software "easy to service."\t\t•IBM wrote "clunky" code that was top-heavy with lines of documentation to make the software "easy to service."\t\t•IBM wrote'], 'source': {'query': 'ibm', '_id': '174', 'text': 'writers were contemptuous of IBM and it\'s coding culture. In the increasingly irrelevant world of IBM, the classical languages were COBOL, PL/1, and BAL (Basic Assembly Language), NOT C! J. In addition, IBM wrote "clunky" code that was top-heavy with lines of documentation to make the software "easy to service." K. Finally, in December 1987 OS/2 1.0 without Presentation Manager ', 'doc_ID': 1, 'block_ID': 173, 'page_num': 35, 'content_type': 'text', 'author_or_speaker': 'IBM_User', 'special_field1': '', 'file_source': 'Bill-Gates-Biography.pdf', 'added_to_collection': 'Mon Jul 1 13:14:36 2024', 'table': '', 'coords_x': 162, 'coords_y': 414, 'coords_cx': 34, 'coords_cy': 45, 'external_files': '', 'score': -4.040003091801133, 'similarity': 0.0, 'distance': 0.0, 'matches': [[29, 'ibm'], [100, 'ibm'], [215, 'ibm']], 'account_name': 'llmware', 'library_name': 'microsoft_history_0210_1'}}
```
The beauty of the output is the structured nature. You could easily write a program to hand off your report to, a program that wouldn't need to waste precious time parsing natural language and could just flip to the right part of the dictionary. Besides saving time, you also increase accuracy and consistency.

1,908,998 | Mastering SQL Databases: In-Depth Guide | SQL (Structured Query Language) databases are a cornerstone of modern data management systems, widely... | 0 | 2024-07-02T13:29:38 | https://dev.to/vuyokazimkane/mastering-sql-databases-in-depth-guide-3i4b | sql, sqlserver, programming | SQL (Structured Query Language) databases are a cornerstone of modern data management systems, widely favored for their reliability and versatility. Let's delve deeper into what makes SQL databases essential for managing structured data.
**What are SQL Databases?**
SQL databases, or Relational Database Management Systems (RDBMS), organize data into structured tables. Each table consists of rows and columns, where rows represent individual records and columns define the attributes of those records. These databases use SQL to interact with data, facilitating tasks like querying, updating, and managing database structures.
### Key Features of SQL Databases
1. **Relational Model:** Data is structured into tables linked by common keys, enabling efficient data retrieval and manipulation.
2. **Structured Query Language (SQL):** SQL serves as the standard language for managing relational databases, offering powerful commands for data operations.
3. **ACID Properties:** Ensures reliability with ACID principles:
- **Atomicity:** Transactions are treated as indivisible units, ensuring all or none of the transaction's operations are executed.
- **Consistency:** Data remains in a consistent state before and after transactions.
- **Isolation:** Transactions operate independently of each other to prevent interference.
- **Durability:** Once transactions are committed, changes are permanent even in the event of system failure.
4. **Schema-Based:** SQL databases enforce a predefined schema that dictates the structure of tables, columns, and data types, ensuring data integrity and consistency.
5. **Data Integrity:** Enforces rules to maintain data accuracy and reliability, such as constraints, validations, and referential integrity.
### Common SQL Databases
1. **MySQL:** Widely used in web applications for its speed, reliability, and ease of use.
2. **PostgreSQL:** Known for its advanced features, scalability, and support for complex queries and data types.
3. **Microsoft SQL Server:** A robust, enterprise-grade RDBMS with comprehensive data management tools.
4. **Oracle Database:** Highly scalable and secure, ideal for large-scale enterprise applications.
5. **SQLite:** Lightweight and self-contained, perfect for mobile apps and small-scale projects.
### Common SQL Commands
- **SELECT:** Retrieves data from one or more tables based on specified conditions.
```
SELECT * FROM employees WHERE department = 'Sales';
```
- **INSERT:** Adds new records into a table.
```
INSERT INTO employees (name, position, salary) VALUES ('John Doe', 'Manager', 75000);
```
- **UPDATE:** Modifies existing records in a table.
```
UPDATE employees SET salary = 80000 WHERE name = 'John Doe';
```
- **DELETE:** Removes records from a table.
```
DELETE FROM employees WHERE name = 'John Doe';
```
- **CREATE TABLE:** Defines a new table and its structure within the database.
```
CREATE TABLE employees (
id INT PRIMARY KEY,
name VARCHAR(100),
position VARCHAR(50),
salary DECIMAL(10, 2)
);
```
### Use Cases
- **Data Warehousing:** Storing and analyzing large volumes of data efficiently.
- **Transaction Processing:** Managing transactions in sectors like banking and retail.
- **Content Management:** Backend storage for content management systems (CMS) and web applications.
- **CRM Systems:** Storing customer data and interactions for effective relationship management.
### Conclusion
SQL databases continue to dominate the database landscape due to their reliability, scalability, and the universal adoption of SQL as a querying language. Whether powering critical enterprise applications or supporting small-scale projects, SQL databases offer a robust framework for managing structured data effectively.

I have a custom-made cgi application I'd like to use react with, and I'm trying to find my way around how to stuff dynamically-generated links in the output, that are needed on a per-requeset, per-session, and per-customer basis.
I started by building a page having only an AppBar with a menu and three items on it, just to see if I could find my way in, but whenever I build it for production, and whenever I use routes or not, these links get moved into some js chunk it wouldn't be feasible to work with.
Ideally, I'd like to output the html with the links already set, and have it pulling js and css chunks from the server as needed.
Have also thought on using `fetch' to pull these from the server, but I'd prefer a more static solution. Is there some known way around this? maybe even pre-rendering even exists and I could output such pre-rendered page stuffing the links where needed?
Any ideas welcome.
Thanks,

1,908,970 | Building Robust Typescript APIs with the Effect Ecosystem | Introduction In this post, we will explore how to create a complete API using the Effect... | 0 | 2024-07-02T13:22:13 | https://dev.to/martinpersson/building-robust-typescript-apis-with-the-effect-ecosystem-1m7c | typescript, beginners, tutorial, api | #Introduction
In this post, we will explore how to create a complete API using the Effect ecosystem. Although the Effect documentation is excellent, there are not many examples of full applications.
If you have never heard of Effect, I suggest you take a look at the website: https://effect.website/
Effect is not just another framework but instead acts as the missing standard library for TypeScript. Because of this, I believe Effect is truly the future for TypeScript, especially when considering the challenges associated with writing production-ready applications in "plain" TypeScript. To understand more about these challenges and how Effect addresses them, watch this insightful video by Johannes Schickling, the founder of Prisma: https://www.youtube.com/watch?v=PxIBWjiv3og&ab_channel=Effect%7CTypeScriptatScale.
The purpose of this post is to demonstrate how to use the different components of the Effect ecosystem to build a modern API:
* Effect: The core module for handling and creating effects.
* Effect Schema: Use schemas to validate and transform data.
* Effect SQL: A toolkit for integration with SQL databases. We will use PostgreSQL in our example.
* Effect Platform/Node: Allows us to use the Node.js platform. We will use this to create our server, router, and handle external API calls.
* Effect opentelemetry: Lets us get tracing and metrics for our app. We integrate it to our console but its really easy to setup in honeycomb for example
By utilizing these modules from Effect, we gain massive benefits. Everything is type-safe, we have robust error handling, and there's no need to reach out to NPM for specific packages. Everything is included in Effect.
Make sure you clone the GitHub repo to see the complete code.
Link to repo: https://github.com/Mumma6/effect-node-server
#Overview of the Project
This project involves building a straightforward application that allows you to create user profiles and add movies to these profiles. It incorporates basic CRUD (Create, Read, Update, Delete) operations, external API calls with movie details fetched from the OMDb API. All data, including user profiles and associated movie information, is stored in a PostgreSQL database.
The system's design is inspired by Domain-Driven Design (DDD), where "User" and "Movie" are treated as distinct domains. This approach facilitates managing complex functionalities and maintaining clear boundaries between different areas of concern within the application making it an excellent starting point and foundation to build upon.
##Design
###Domain Layer
The domain layer is divided into user and movie domains, each containing the following sub-layers:
**Models:** Define the data structures and schemas.
**Repositories:** Handle data access and database operations.
**Infrastructure:** Handle external API calls (movie only).
**Services:** Implement business logic and orchestrate calls to repositories and external APIs (for the movie domain).
###Routes Layer
The routes layer defines the HTTP routes for the API. Each domain has its own set of routes:
**User Routes:** Handles user-related operations (create, read, update, delete).
**Movie Routes:** Handles movie-related operations (create, read, update, delete) and integrates with the OMDb API.
###Lib Layer
The lib layer contains configuration and setup for the database:
**Database:** Contains configuration and initialization logic for connecting to PostgreSQL using the Effect library.
###Entry Point
**index.ts:** The main entry point of the application. It initializes the application by setting up routes and starting the server.
## Code
Rather than guiding you through a step-by-step coding tutorial, I'll highlight crucial code snippets from our project. This approach will focus on explaining the concepts and the architecture behind the implementation, offering insights into how the Effect ecosystem seamlessly integrates into our application.
###Dependencies
The project uses these dependencies
```ts
"dependencies": {
"@effect/opentelemetry": "^0.34.29",
"@effect/platform": "^0.58.16",
"@effect/platform-node": "^0.53.15",
"@effect/schema": "^0.68.14",
"@effect/sql": "^0.4.16",
"@effect/sql-pg": "^0.4.16",
"@opentelemetry/sdk-metrics": "^1.25.1",
"@opentelemetry/sdk-trace-base": "^1.25.1",
"@opentelemetry/sdk-trace-node": "^1.25.1",
"dotenv": "^16.4.5",
"effect": "^3.4.5",
"ts-node-dev": "^2.0.0",
"typescript": "^5.5.2"
}
```
###Entry point
In our `index.ts`, we initialize the server and the router. We provide all the necessary Layers for the project, similar to "dependency injection." This setup ensures that each component has access to the resources it needs to function correctly.
We also have the ability to add our custom middleware. Notably, the `NodeRuntime.runMain` function acts as the starting point of our entire application. This function boots up the server, ensuring that all configurations and services are loaded and ready to handle requests.
```ts
import { HttpMiddleware, HttpRouter, HttpServer, HttpServerResponse } from "@effect/platform"
import { NodeHttpServer, NodeRuntime } from "@effect/platform-node"
import { Effect, Layer } from "effect"
import { createServer } from "http"
import { DatabaseInitialisation, SqlLive } from "./lib/database"
import { AppRouter } from "./routes/routes"
import { UserService } from "./domain/user/service/user.service"
import { MovieService } from "./domain/movies/service/movie.service"
import { TracingConsole } from "./lib/tracing"
const myLogger = HttpMiddleware.make((app) =>
Effect.gen(function* () {
console.log("LOGGED")
return yield* app
})
)
const ServerLive = NodeHttpServer.layer(createServer, { port: 5000, host: "localhost" })
const HttpLive = HttpRouter.Default.unwrap(HttpServer.serve(myLogger)).pipe(
Layer.provide(AppRouter),
Layer.provide(ServerLive),
Layer.provide(UserService.Live),
Layer.provide(MovieService.Live),
Layer.provide(DatabaseInitialisation.Live),
Layer.provide(SqlLive),
Layer.provide(TracingConsole)
)
NodeRuntime.runMain(Layer.launch(HttpLive))
```
###Lib folder
In the `lib` directory, we define the structure of our database by creating tables and setting up the connection details for our PostgreSQL client. Typically, you would retrieve these connection details from environment variables specified in your .env file to enhance security and flexibility. However, for simplicity in this demonstration, I have hardcoded them directly into the configuration files.
```ts
import { PgClient } from "@effect/sql-pg"
import { Config, Context, Effect, Layer, Redacted } from "effect"
const make = Effect.gen(function* () {
const sql = yield* PgClient.PgClient
// Suppress NOTICE messages
yield* sql`SET client_min_messages TO WARNING;`
// Create users table if it does not exist
yield* sql`CREATE TABLE IF NOT EXISTS users (
id SERIAL PRIMARY KEY,
name VARCHAR(255) NOT NULL,
email VARCHAR(255) NOT NULL,
created_at TIMESTAMP NOT NULL DEFAULT NOW(),
updated_at TIMESTAMP NOT NULL DEFAULT NOW()
);`
// Create movies table if it does not exist
yield* sql`CREATE TABLE IF NOT EXISTS movies (
id SERIAL PRIMARY KEY,
user_id INTEGER NOT NULL REFERENCES users(id) ON DELETE CASCADE,
title VARCHAR(255) NOT NULL,
year VARCHAR(4),
genre VARCHAR(255),
plot TEXT,
imdb_id VARCHAR(255),
created_at TIMESTAMP NOT NULL DEFAULT NOW(),
updated_at TIMESTAMP NOT NULL DEFAULT NOW()
);`
})
export class DatabaseInitialisation extends Context.Tag("DatabaseInitialisation")<DatabaseInitialisation, Effect.Effect.Success<typeof make>>() {
static readonly Live = Layer.effect(this, make)
}
export const SqlLive = PgClient.layer({
database: Config.succeed("effect"),
host: Config.succeed("localhost"),
username: Config.succeed("postgres"),
port: Config.succeed(5432),
password: Config.succeed(Redacted.make("123")),
})
```
In addition to database configurations, our lib directory also sets up tracing to monitor and diagnose application performance. For details on integrating with alternative tracing services like Honeycomb, refer to the GitHub repository.
```ts
import * as NodeSdk from "@effect/opentelemetry/NodeSdk"
import { BatchSpanProcessor, ConsoleSpanExporter } from "@opentelemetry/sdk-trace-base"
export const TracingConsole = NodeSdk.layer(() => ({
resource: { serviceName: "example" },
spanProcessor: new BatchSpanProcessor(new ConsoleSpanExporter()),
}))
```
###Routing
The `routes.ts` file plays a crucial role in our application by organizing and managing all the routing configurations. Currently, it handles two primary routes: one for movies and another for users. However, the structure is designed to be extensible, allowing for the easy addition of more routes as the application grows.
Each route is grouped within its respective module, and specific route implementations are equipped with necessary dependencies using the `Layer.provide` method. This setup ensures that each route has access to the services and data layers it requires to function correctly.
```ts
import { HttpRouter } from "@effect/platform"
import { Effect, Layer } from "effect"
import { UserRoutes, UsersRouter } from "./users/users.routes"
import { MoviesRouter, MovieRoutes } from "./movies/movies.routes"
export const AppRouter = HttpRouter.Default.use((router) =>
Effect.gen(function* () {
yield* router.mount("/users", yield* UsersRouter.router)
yield* router.mount("/movies", yield* MoviesRouter.router)
})
).pipe(Layer.provide(UserRoutes), Layer.provide(MovieRoutes))
```
The `MoviesRouter` handles routing for movie-related requests. It's defined as a specialized router with a unique tag, which helps in organizing and isolating movie-related routes within the larger application. Here’s how we define and organize these routes:
```ts
export class MoviesRouter extends HttpRouter.Tag("MoviesRouter")<MoviesRouter>() {}
export const MovieRoutes = Layer.mergeAll(GetMovies, CreateMovie, UpdateMovie, GetMovieById, GetMoviesForUserId, DeleteMovieById).pipe(
Layer.provideMerge(MoviesRouter.Live)
)
```
In this setup, we use `Layer.mergeAll` to combine various movie-related route handlers like `GetMovies`, `CreateMovie`, and others into a single layer. This layer is then provided to the `MoviesRouter` using `Layer.provideMerge`, ensuring that all route handlers have access to the necessary dependencies and configurations.
The `GetMovies` route demonstrates how we handle a typical GET request to fetch all movies. This route uses services from the domain layer to perform its operations and includes robust error handling to manage potential issues during execution:
```ts
import { HttpRouter, HttpServerRequest, HttpServerResponse } from "@effect/platform"
import { Effect, Layer, pipe } from "effect"
import { Schema } from "@effect/schema"
import { MovieService } from "../../domain/movies/service/movie.service"
const GetMovies = MoviesRouter.use((router) =>
pipe(
MovieService,
Effect.flatMap((service) =>
router.get(
Routes.All,
Effect.gen(function* () {
const movies = yield* service.getAllMovies()
return yield* HttpServerResponse.json(movies)
}).pipe(
Effect.catchTags({
ParseError: (error) =>
HttpServerResponse.json({ message: "Invalid request data for fetching all movies", details: error.message }, { status: 400 }),
SqlError: (error) =>
HttpServerResponse.json({ message: "Database error while fetching all movies", details: error.message }, { status: 500 }),
HttpBodyError: (error) =>
HttpServerResponse.json(
{ message: "Error processing request body while fetching all movies", details: error.reason },
{ status: 400 }
),
}),
Effect.withSpan("GetAllMoviesRoute")
)
)
)
)
)
```
**Key Features:**
* Service Integration: The route integrates with MovieService to fetch all movies, encapsulating business logic and data fetching in a service layer.
* Error Handling: Robust error handling is implemented using Effect.catchTags. This method catches and handles different types of errors, allowing the application to respond with appropriate HTTP status codes and error messages:
**ParseError:** Catches errors related to request data parsing.
**SqlError:** Handles errors that occur during database operations.
**HttpBodyError**: Manages errors related to processing the HTTP request body.
* Distributed Tracing: Effect.withSpan("GetAllMoviesRoute") is used for adding tracing to monitor the performance and troubleshoot issues in the route execution.
By structuring routes in this manner, we ensure that our application not only efficiently handles operations but also gracefully manages errors, providing clear feedback to the client and maintaining the integrity of the application.
###Service
The `MovieService` is responsible for movie-related functionalities in our application. It acts as an intermediary between the `MovieRepository`, which handles database operations, and `MovieInfrastructure`, which deals with external API calls to fetch additional movie details.
Here’s how the service is structured:
```ts
const make = Effect.gen(function* () {
const repository = yield* MovieRepository
const infrastructure = yield* MovieInfrastructure
const getAllMovies = () => repository.getAllMovies()
const getMovieById = (id: string) =>
pipe(
repository.GetMovieById(id),
Effect.map(
Option.match({
onNone: () => "Movie not found",
onSome: (movie) => movie,
})
)
)
// rest of the service implementations
return {
getAllMovies,
getMovieById,
createMovie,
updateMovie,
deleteMovie,
getMoviesByUserId,
} as const
})
export class MovieService extends Context.Tag("MovieService")<MovieService, Effect.Effect.Success<typeof make>>() {
static readonly Live = Layer.effect(this, make)
}
```
###Infrastructure
The `MovieInfrastructure` layer in our application is specifically designed to handle all external API interactions. In this example, we focus on fetching movie information from the OMDb API, but the structure is scalable to accommodate multiple external API sources as needed. This modularity ensures that extending our application to integrate with additional services is straightforward.
```ts
import { Config, Context, Effect, Layer, pipe } from "effect"
import { HttpClientRequest, HttpClient } from "@effect/platform"
import { ApiMovieSchema } from "../models/movie.model"
const basePath = "http://www.omdbapi.com/"
const make = Effect.gen(function* () {
const key = yield* Config.string("OMDB_KEY")
const getMovieInformation = (name: string) =>
pipe(
HttpClientRequest.get(`${basePath}?t=${name}&apikey=${key}`),
HttpClient.fetch,
ApiMovieSchema.decodeResponse,
Effect.retry({ times: 3 }),
Effect.withSpan("GetMovieInformation")
)
return {
getMovieInformation,
} as const
})
export class MovieInfrastructure extends Context.Tag("MovieInfrastructure")<MovieInfrastructure, Effect.Effect.Success<typeof make>>() {
static readonly Live = Layer.effect(this, make)
}
```
In the "models" directory we define the expected structure of the JSON response from the OMDb API. Each field like Title is mapped directly to the corresponding field in the API response.
**Decoding Method:** decodeResponse is a static method that wraps around the schema to provide a convenient way to parse and validate the JSON body of the HTTP response. It ensures that the incoming data matches our specified schema, which is critical for maintaining the integrity and consistency of the data used within our application.
```ts
export class ApiMovieSchema extends Schema.Class<ApiMovieSchema>("ApiMovieSchema")({
Title: Schema.String,
// Many more fields here...
}) {
static decodeResponse = HttpClientResponse.schemaBodyJsonScoped(ApiMovieSchema)
}
```
###Repository
The repository layer in our application is crucial for handling all database interactions. It uses SQL providers to communicate with the database, leveraging schemas to define the data structures expected from the database responses and to format the data sent in queries.
Here’s how we define and structure the `MovieRepository`:
```ts
import { Schema } from "@effect/schema"
import { PgClient } from "@effect/sql-pg"
import { Context, Effect, Layer } from "effect"
import { SqlResolver, SqlSchema } from "@effect/sql"
import { InsertMovieSchema, Movie, UpdateMovieSchema } from "../models/movie.model"
const make = Effect.gen(function* () {
const sql = yield* PgClient.PgClient
const AddMovie = yield* SqlResolver.ordered("InsertMovie", {
Request: InsertMovieSchema,
Result: Movie,
execute: (requests) => sql`INSERT INTO movies ${sql.insert(requests)} RETURNING *`,
}).pipe(Effect.withSpan("AddMovieResolver"))
// rest of the implementations
return {
addMovie: AddMovie.execute,
GetMovieById: GetMovieById.execute,
getAllMovies: GetAllMovies,
updateMovie: UpdateMovie.execute,
deleteMovie: DeleteMovie.execute,
getMovieByUserId: GetMovieByUserId,
} as const
})
export class MovieRepository extends Context.Tag("MovieRepository")<MovieRepository, Effect.Effect.Success<typeof make>>() {
static readonly Live = Layer.effect(this, make)
}
```
#Conclusion
Throughout this post, we've explored how to build a complete and modern API using the Effect ecosystem. From setting up an organized and efficient routing system to integrating external API services and managing database interactions seamlessly, the Effect library has shown its strength in creating scalable and maintainable backend applications.

1,908,993 | Theme your project using Tailwind css | When it comes to designing modern web applications, Tailwind CSS has quickly become a popular choice... | 0 | 2024-07-02T13:21:04 | https://codeparrot.ai/blogs/how-to-set-tailwind-background-color-and-color | webdev, tailwindcss, frontend, css | When it comes to designing modern web applications, Tailwind CSS has quickly become a popular choice among developers. It offers utility-first CSS classes that allow for rapid and flexible development. In this blog, we'll dive into how to set Tailwind background color and Tailwind color using its built-in classes, and see how to create custom colors. Let's get started!
## What is Tailwind?
Tailwind CSS is a utility-first CSS framework that provides low-level utility classes to build custom designs without writing custom CSS. Instead of focusing on predefined components, Tailwind gives you the tools to style your website directly in your HTML, making the styling process more intuitive and maintainable.
## Why Tailwind?
1. **Rapid Development**: With its utility classes, Tailwind allows for faster development by minimizing the need to write custom CSS.
2. **Responsive Design**: Tailwind's classes include responsive variants, making it easy to create designs that work across different screen sizes.
3. **Customization**: Tailwind is highly customizable, allowing you to extend its default theme or create a completely unique design system.
4. **Consistency**: By using a set of predefined utility classes, you can ensure consistency in design across your project.
## Tailwind Background Color Classes
Tailwind CSS provides a wide range of background color classes that you can use to style your elements. Here's a basic example:
```html
<div class="bg-red-500 p-4 text-white">
This div has a red background color!
</div>
<div class="bg-green-500 p-4 text-white mt-4">
This div has a green background color!
</div>
<div class="bg-yellow-500 p-4 text-white mt-4">
This div has a yellow background color!
</div>
<div class="bg-purple-500 p-4 text-white mt-4">
This div has a purple background color!
</div>
```
{% codepen https://codepen.io/xocdnrjf-the-scripter/pen/QWRXeEv %}
## Setting Custom Tailwind Background Colors
If the default background colors provided by Tailwind don't meet your needs, you can easily extend the color palette. First, you'll need to configure your `tailwind.config.js` file:
```javascript
module.exports = {
theme: {
extend: {
backgroundColor: {
'custom-blue': '#5A67D8',
}
}
}
}
```
Then, you can use your custom color class in your HTML:
```html
<div class="bg-custom-blue p-4 text-white">
This div has a custom blue background color!
</div>
```
## Tailwind Color Classes
In addition to background colors, Tailwind also provides classes for setting text colors. Here's a quick example:
```html
<p class="text-blue-500">
This paragraph has blue text color!
</p>
<p class="text-green-500 mt-4">
This paragraph has green text color!
</p>
<p class="text-yellow-500 mt-4">
This paragraph has yellow text color!
</p>
<p class="text-purple-500 mt-4">
This paragraph has purple text color!
</p>
```
{% codepen https://codepen.io/xocdnrjf-the-scripter/pen/gOJNNEY %}
## Setting Custom Tailwind Colors
Just like with background colors, you can customize text colors in your `tailwind.config.js` file:
```javascript
module.exports = {
theme: {
extend: {
textColor: {
'custom-red': '#E53E3E',
}
}
}
}
```
Now you can use your custom text color class:
```html
<p class="text-custom-red">
This paragraph has a custom red text color!
</p>
```

1,908,992 | Bullet-proof user stories for your team - with AI Prompts to do them! | What are the user stories? In the dynamic world of product development and engineering,... | 0 | 2024-07-02T13:21:01 | https://dev.to/brownio/bullet-proof-user-stories-for-your-team-with-ia-prompts-to-do-them-17g3 | productivity, beginners, startup, writing | ## What are the user stories?
In the dynamic world of product development and engineering, **effective communication and collaboration are critical to a project's success**. User stories serve as the backbone of agile methodologies, providing a clear and concise way to capture user requirements and translate them into actionable tasks for the development team.
When done right, user stories can drive alignment, foster collaboration, and streamline the development process. However, crafting user stories that are truly "bullet-proof" requires a blend of art and science. It involves understanding the core principles of** effective storytelling**, embracing **best practices**, and continuously refining the process based on feedback and real-world experience.
## What will you learn
In this article, we will delve into **what makes a user story rock-solid**, and why it is essential for your team's success. We will explore the key characteristics of high-quality user stories, provide practical tips for writing them, and discuss how to avoid common pitfalls.
Whether you are a product manager, a developer, or a stakeholder, mastering the art of bullet-proof user stories will empower you to deliver products that truly resonate with your users, and will make your peer's life easier.
Also, we'll speak about a method called **Gherkin**, used for highly-technical tickets that are aimed to both devs and non-technical profiles.
##Understanding User Stories
User stories are **concise**, simple descriptions of a feature told from the perspective of the end user. They focus on what the user needs and why. Typically, they follow a basic format:
**Template**: "As a [**type of user**], I want [**an action**] so that [**a benefit**]."
**Purpose**: To capture user requirements and facilitate clear communication between stakeholders and development teams.
##Characteristics of Bullet-Proof User Stories
- **Clarity**: Easy to understand with no ambiguity.
- **Conciseness**: Brief yet comprehensive enough to convey the necessary information.
- **Specificity**: Provides sufficient detail without being overly prescriptive.
These stories should follow the **INVEST** criteria, which stands for independent, negotiable, valuable, estimable, small, and testable.
###INVEST Criteria
- **Independent**: The story should stand alone, allowing it to be developed and delivered independently of other stories.
- **Negotiable**: Stories should be flexible and open to discussion and modification.
- **Valuable**:Each story should provide value to the user or customer.
- **Estimable**:The team should be able to estimate the effort required to complete the story.
- **Small**:The story should be small enough to be completed in a single iteration or sprint.
- **Testable**:There should be clear criteria to determine when the story is complete and meets the requirements.
Also, good acceptance criteria are key because they help the team and other developers grasp the fundamental technical details of a task.
## Acceptance Criteria
Acceptance criteria **specify the requirements that need to be fulfilled to meet the user's needs** as described in the user story. They provide a clear definition of done, helping to prevent misunderstandings and scope creep during development. Essentially, acceptance criteria outline the conditions under which the user story can be considered satisfactorily implemented and ready for testing and deployment.
###How Should Acceptance Criteria Be?
Acceptance criteria should be:
- **Specific**: Clearly define what needs to be achieved and what constitutes success.
- **Measurable**: Provide a way to objectively verify when the criteria are met.
- **Achievable**: Realistic and feasible within the project constraints.
- **Relevant**: Directly related to the user story and its intended outcome.
- **Time-bound**: Clearly state when the acceptance criteria should be fulfilled.
Overall, here's an example of a bad vs a good user story about the necessity of adding a new cookie banner for a promotional campaign, that will show specific content depending on wether the user accepts or not:
###Bad Example of a User Story
```
Title: Show Cookie Banner
User Story:
As a user,
I want a cookie banner,
so that cookies are handled.
Acceptance Criteria:
- Display a cookie banner.
```
Yeah, but, what should happen when user declines? How long should the cookies stay on the browser?, Should we keep showing it if the user accepts?
Above, you'd be failing the achieve most of the acceptance criteria and user story criteria (except for the Small one...)
###Good Example of a User Story
```
User Story:
As a new user that enters the website for the first time,
I want a cookie banner to be displayed to me,
so that cookies can be stored in my browser to determine what to display on the website during the promotional campaign.
Acceptance Criteria:
- Upon first visit, a prominent cookie banner is displayed at the bottom of the website (Check design files below).
- The banner includes options to "Accept" or "Decline" cookies.
- It remains visible until the user makes a choice.
- If the user clicks "Accept," cookies are stored in the browser to record their preference.
- If the user clicks "Decline," no cookies are stored, and the banner remains visible on subsequent visits.
- Component A, related to tracking order status, is shown only if the user accepts cookies.
- If cookies are declined, Component A remains hidden.
- The user's cookie preference is remembered across sessions and visits to the website.
- The banner does not reappear after the user has made a choice unless they clear their browser cookies.
- Ensure the cookie banner and options are accessible to all users, including those using assistive technologies.
- Ensure compliance with legal requirements for cookie consent and user privacy regulations. Link in the cookie banner should forward the user to https://web.xyz/legal on a new tab.
- Verify that the cookie banner appears correctly on different browsers and devices.
```
Here, you can see it's still small, concise, easier to estimate, specific, and testable.
Now, the promised prompts for creating good user stories using tools or models like GPT, Gemini, or Copilot. Always be as informative as possible, like so:
```
Delete everything from before. As if you were Senior Product Owner, Can you please generate a good user story following this format: 'As a [new user that entered the website for the first time], I want [a cookie banner to be displayed to the user] so that [we can store the cookies in the user's browser to decide what to show on the website]'? [The user story should be related to a new feature for a shopping website with a promotional campaign that allows users to track their order status. Component A should be shown only is user accepts the cookies] Please add an extensive and concise acceptance criteria for the developers to understand. Ask me if there is any doubt on what fields are we working, if any data or description is incomplete, on or anything relevant.
```
Be sure to adapt everything that's between the "[ ]" so it matches your story.
##The Gherkin Method
Gherkin is a structured language used to describe scenarios in a way that is **easy to understand by both technical and non-technical stakeholders**. It's primarily used in [BDD](https://cucumber.io/docs/bdd/) (a way for software teams to work that closes the gap between business people and technical people) to define acceptance criteria and specify how software should behave in various scenarios.
### When is Gherkin used?
Gherkin is typically used in agile environments, where collaboration between business analysts, developers, and testers is essential. It helps **ensure that everyone has a clear understanding of the expected behavior** of a feature or system.
A normal user story, as described earlier, typically follows a format that outlines the who, what, and why of a feature from a user's perspective. On the other hand, Gherkin is more structured and focuses on specifying the behavior of the software through scenarios written in a specific syntax.
### Characteristics of a Gherkin story
- **Structure**: Gherkin scenarios are structured using keywords like Feature, Scenario, Given, When, and Then, which provide clear steps and expected outcomes.
- **Human-Readable**: Gherkin scenarios are written in plain, understandable language that can be easily read and understood by both technical and non-technical stakeholders.
- **Automation**: Scenarios written in Gherkin can often be directly used as automated tests. They can also be used as documentation.
###Structure explanation
####Feature
The Feature keyword is used to define a high-level description of a feature or functionality that is being tested. It provides context about what aspect of the system the scenarios are related to.
```
Feature: Login Functionality
As a user,
I want to be able to log into the system,
So that I can access my account and manage my profile.
```
#### Scenario
The Scenario keyword is used to define specific test scenarios or examples that illustrate how the system should behave under certain conditions. Each scenario typically represents a specific use case or user story.
```
Scenario: Successful Login
Given the user is on the login page
When the user enters valid credentials
And clicks on the login button
Then the user should be logged into their account
And redirected to the dashboard page.
```
####Steps: Given, When, Then, And, But
**Given**: Specifies the initial state or precondition of the scenario. It sets up the context in which the scenario takes place.
**When**: Describes the action or event that occurs that triggers the behavior being tested.
**Then**: Defines the expected outcome or result of the action specified in the When step. It verifies the expected behavior of the system.
**And, But**: These keywords are used to continue the previous step (Given, When, or Then) to add additional context or conditions as needed.
```
Scenario: Search for a Product
Given the user is on the homepage
When the user enters "smartphone" in the search bar
And clicks on the search button
Then the search results page should display relevant products
And the user should be able to filter and sort the results.
```
### Optionals for Gherkin
**Background**: Optional Gherkin keyword used to define steps that are common to all scenarios within a feature file. It helps in setting up a consistent starting state for scenarios, reducing redundancy. [Read more here.](https://cucumber.io/docs/gherkin/reference/#background)
**Scenario Outline**: Optional Gherkin keyword used to define a template for scenarios that vary only in their inputs or data. It allows for parameterization of scenarios using placeholders, which are replaced with concrete values in each scenario instance. [Read more here.](https://cucumber.io/docs/gherkin/reference/#scenario-outline)
Overall, let's see what a complete Gherkin story should look like for the example from before
### Example of a Gherkin story
```
Feature: Cookie Consent Banner
As a new user visiting the shopping website,
I want to see a cookie banner
So that my preferences can be recorded and I can view relevant promotional content.
Scenario: Display Cookie Banner
Given I am a new user
When I visit the shopping website
Then I should see a cookie banner with options to accept or decline cookies
Scenario: Accept Cookies
Given I am a new user
And I see the cookie banner
When I click on "Accept"
Then cookies should be stored in my browser
And I should be able to view promotional content related to the campaign
Scenario: Decline Cookies
Given I am a new user
And I see the cookie banner
When I click on "Decline"
Then cookies should not be stored in my browser
And Component A, which allows users to track their order status, should not be displayed
```
And now, a good AI prompt to generate the Gherkin story, remember to change what's inside the "[ ]":
```
Delete everything from before. As if you were Senior Product Owner, Can you please generate a good user story following the Gherkin format: 'As a [new user that entered the website for the first time], I want [a cookie banner to be displayed to the user] so that [we can store the cookies in the user's browser to decide what to show on the website]'? [The user story should be related to a new feature for a shopping website with a promotional campaign that allows users to track their order status. Component A should be shown only is user accepts the cookies] Ask me if there is any doubt on what fields are we working, if any data or description is incomplete, on or anything relevant.
```
Mastering the creation of bullet-proof user stories is not just about following a template but understanding the nuances of effective communication and stakeholder alignment. By applying these principles, **teams can navigate complexities, mitigate risks, and deliver impactful solutions that resonate with users**.

If you still don't understand why the... | 0 | 2024-07-02T13:08:17 | https://dev.to/maxflower/how-golang-will-solve-your-first-working-task-3kpc | go, api, beginners, development | Golang, or just Go, has become known as the Go gopher language. If you still don't understand why the gopher you can find a surprising mascot history in this [article](https://go.dev/blog/gopher). Well, let's get it started from the beginning, Golang has become known as one of the most productive programming languages out there. Unlike traditional languages like Java or Python, Go strikes a unique balance between easy-to-write code and quick execution, speeding up development and cutting down on debugging and testing time. This article will look at a real-world example of using goroutines and context in a project that interacts with a slow and unstable REST API microservice.
**The Task**
Let's imagine you have just joined the team and your team lead asks you to bind a new microservice written in Golang (for example the risk manager) to the user microservice exposed through REST API.
**The Problem**
The risk manager needs to interact with a REST API that can be slow and unstable, requiring us to handle such requests carefully. I will use goroutines for asynchronous HTTP requests and context to manage request timeouts and error handling.
**The solution**
Using goroutines and context in Golang allows efficient management of concurrent tasks and handling of slow or unstable external APIs.
The first step to interpreting it in a code is to create the API, I used the shareware service **_https://mockapi.io/_** It is convenient to generate a REST API with a basic set of entities, such as **users**.
Let’s say someone tried their best and your company has an internal service that lists users. Our task is to reuse the user list in the new risk manager (the user data structure satisfies the contract described by **mockapi.io**). The code below makes a request, processes the body, and produces either a list of users or the corresponding error.
```go
type User struct {
CreatedAt string
Name string
Avatar string
Id string
}
// Original slow request
func fetchUsers(ctx context.Context) (*[]User, error) {
resp, err := http.Get("https://<use your id after sign up>.mockapi.io/api/v1/users")
if err != nil {
return nil, err
}
defer resp.Body.Close()
if resp.StatusCode != http.StatusOK {
return nil, fmt.Errorf("failed to fetch users: %s", resp.Status)
}
var users []User
if err := json.NewDecoder(resp.Body).Decode(&users); err != nil {
return nil, err
}
return &users, nil
}
```
To control the operation, I will use the topmost parent context for all other contexts - `context.Background`. I will supplement this context with new data, in this case the timeout - `context.WithTimeout`, which I will define as 2 seconds. You can read more about working with contexts in Go in this [article](https://go.dev/blog/context).
```go
ctx, cancel := context.WithTimeout(context.Background(), 2*time.Second)
defer cancel()
usersChan := make(chan *[]User)
errChan := make(chan error)
go func() {
users, err := fetchUsers(ctx)
if err != nil {
errChan <- err
return
}
usersChan <- user
}()
select {
case users := <-usersChan:
fmt.Printf("Fetched users: %+v\n", users)
case err := <-errChan:
fmt.Printf("Error fetching users: %v\n", err)
case <-ctx.Done():
fmt.Println("Request timed out")
}
```
In the example, I use two channels - usersChan to record the result received from our internal service, and the second channel errChan - to record the error.
If the response from a slow API does not arrive within 2 seconds, we detect an error and give the opportunity to correctly process it on an external layer.
In this practical example with the risk manager, goroutines enabled asynchronous HTTP requests, while context ensured timeout handling, which is critical for building reliable and resilient microservices.
P.S.
This article is intended for beginner developers who have basic knowledge, but little idea of where they can apply their knowledge. I will be glad to receive your feedback and will be happy to answer your questions.
A working example and several other implementations of the most basic things in the Go language can be found on my GitHub, at the [link](https://github.com/MaxFlower/go-tasks/blob/main/api/api.go)

1,908,980 | Integrating FluxCD with Other CI/CD Tools | FluxCD is a popular open-source tool for automating the deployment of applications to Kubernetes... | 0 | 2024-07-02T13:06:13 | https://dev.to/platform_engineers/integrating-fluxcd-with-other-cicd-tools-3ceo | FluxCD is a popular open-source tool for automating the deployment of applications to Kubernetes clusters. It provides a robust and flexible way to manage the lifecycle of applications, from source code to production. However, in many cases, FluxCD is not used in isolation but rather as part of a larger CI/CD pipeline that involves other tools. In this blog post, we will explore how to integrate FluxCD with other CI/CD tools to create a comprehensive and efficient pipeline.
### FluxCD Overview
Before diving into the integration details, let's briefly review what FluxCD does. FluxCD is a GitOps tool that automates the deployment of applications to Kubernetes clusters. It does this by continuously monitoring a Git repository for changes and applying those changes to the cluster. This approach ensures that the cluster is always in sync with the desired state defined in the Git repository.
### Integrating FluxCD with Jenkins
Jenkins is a widely used CI/CD tool that provides a robust platform for automating various stages of the software development lifecycle. To integrate FluxCD with Jenkins, we can use the FluxCD Jenkins plugin. This plugin allows us to trigger FluxCD deployments from within Jenkins pipelines.
Here is an example of how to use the FluxCD Jenkins plugin in a Jenkinsfile:
```groovy
pipeline {
agent any
stages {
stage('Deploy to Kubernetes') {
steps {
fluxcdDeploy(
url: 'https://github.com/myorg/myrepo',
credentialsId: 'my-github-credentials',
cluster: 'my-kubernetes-cluster',
namespace: 'my-namespace'
)
}
}
}
}
```
In this example, the `fluxcdDeploy` step is used to trigger a FluxCD deployment. The `url` parameter specifies the Git repository to monitor, `credentialsId` specifies the credentials to use for accessing the repository, `cluster` specifies the Kubernetes cluster to deploy to, and `namespace` specifies the namespace within the cluster.
### Integrating FluxCD with GitLab CI/CD
GitLab CI/CD is another popular CI/CD tool that provides a robust platform for automating various stages of the software development lifecycle. To integrate FluxCD with GitLab CI/CD, we can use the FluxCD GitLab CI/CD template. This template provides a pre-configured `.gitlab-ci.yml` file that can be used to trigger FluxCD deployments.
Here is an example of how to use the FluxCD GitLab CI/CD template:
```yaml
stages:
- deploy
deploy:
stage: deploy
image:
name: docker.io/fluxcd/flux:latest
script:
- flux bootstrap github --owner=myorg --repository=myrepo --branch=main --path=./clusters/my-cluster
- flux create source git myrepo --url=https://github.com/myorg/myrepo --branch=main
- flux create deployment mydeployment --source=myrepo --kustomize=./kustomize
- flux sync --source=myrepo --deployment=mydeployment
```
In this example, the `flux` command is used to bootstrap a FluxCD instance, create a source, create a deployment, and sync the deployment with the source.
### Integrating FluxCD with CircleCI
CircleCI is a cloud-based CI/CD tool that provides a robust platform for automating various stages of the software development lifecycle. To integrate FluxCD with CircleCI, we can use the FluxCD CircleCI orb. This orb provides a pre-configured set of commands that can be used to trigger FluxCD deployments.
Here is an example of how to use the FluxCD CircleCI orb:
```yaml
version: 2.1
orbs:
flux: fluxcd/flux@1.2.0
jobs:
deploy:
executor: flux/default
steps:
- flux/bootstrap:
github:
owner: myorg
repository: myrepo
branch: main
path: ./clusters/my-cluster
- flux/create-source:
name: myrepo
url: https://github.com/myorg/myrepo
branch: main
- flux/create-deployment:
name: mydeployment
source: myrepo
kustomize: ./kustomize
- flux/sync:
source: myrepo
deployment: mydeployment
```
In this example, the `flux` orb is used to bootstrap a FluxCD instance, create a source, create a deployment, and sync the deployment with the source.
In addition to integrating FluxCD with CI/CD tools, it can also be integrated with [platform engineering](www.platformengineers.io) tools such as Terraform. Terraform is a popular infrastructure-as-code tool that provides a robust platform for managing infrastructure.
To integrate FluxCD with Terraform, we can use the FluxCD Terraform provider. This provider allows us to manage FluxCD resources using Terraform.
Here is an example of how to use the FluxCD Terraform provider:
```terraform
provider "flux" {
url = "https://github.com/myorg/myrepo"
credentials {
username = "my-username"
password = "my-password"
}
}
resource "flux_source_git" "myrepo" {
name = "myrepo"
url = "https://github.com/myorg/myrepo"
branch = "main"
}
resource "flux_deployment" "mydeployment" {
name = "mydeployment"
source {
name = flux_source_git.myrepo.name
}
kustomize {
path = "./kustomize"
}
}
```
In this example, the `flux` provider is used to manage FluxCD resources. The `flux_source_git` resource is used to create a source, and the `flux_deployment` resource is used to create a deployment.
### Conclusion
In this blog post, we have explored how to integrate [FluxCD with other CI/CD](https://platformengineers.io/blog/continuous-delivery-using-git-ops-principles-with-flux-cd/) tools such as Jenkins, GitLab CI/CD, and CircleCI. We have also seen how to integrate FluxCD with platform engineering tools such as Terraform. By integrating FluxCD with these tools, we can create a comprehensive and efficient pipeline that automates the deployment of applications to Kubernetes clusters. | shahangita | |

This is my submission of stage zero in the HNG 11 internship, I am currently deep exploring the field of data analysis , I believe this internship gives me the opportunity to learn and grow more in this field
To know more:
- https://hng.tech/internship
- https://hng.tech/hire
## Observation from first glance
Looking at the Iris dataset from first glance,
The Iris flower dataset comprises 150 samples with four features each: sepal length, sepal width, petal length, and petal width, distributed across three species: Iris-setosa, Iris-versicolor, and Iris-virginica, with 50 samples per species
## Exploratory Data Analysis
The pairplot above easily summarizes how the entire distribution of the 4 features are against the target variable.
We can infer all of the above
The pairplot of the Iris dataset provides a visual summary of the relationships between the four features (sepal length, sepal width, petal length, and petal width) for the three Iris species: setosa, versicolor, and virginica. Here are some detailed observations:
1. **Species Separation**:
- **Iris-setosa**: This species is distinctly separated from the other two species in almost all pairwise comparisons. The petal length and petal width features are particularly effective in distinguishing Iris-setosa, as the points representing this species form a distinct cluster in the lower left corner in the petal length vs. petal width plot.
- **Iris-versicolor and Iris-virginica**: These two species overlap more but show some degree of separation. The petal length and petal width features again provide good separation, with Iris-versicolor generally having smaller petal measurements compared to Iris-virginica. However, there is still some overlap between these two species in the middle range of the feature values.
2. **Feature Distributions**:
- The diagonal plots show the kernel density estimates (KDE) for each feature within each species. These plots reveal that the distribution of each feature varies significantly between species. For example, Iris-setosa has a much narrower and distinct distribution for petal length and petal width compared to the other two species.
- Sepal length and sepal width have more overlapping distributions, especially between Iris-versicolor and Iris-virginica, making them less effective for classification on their own.
3. **Inter-feature Relationships**:
- There is a noticeable positive correlation between petal length and petal width across all species, particularly within Iris-versicolor and Iris-virginica.
- Sepal length and petal length also exhibit a positive correlation, especially for Iris-versicolor and Iris-virginica, while Iris-setosa remains distinctly separated.
- Sepal width shows a weaker correlation with other features compared to the petal measurements.
4. **Within-Species Variability**:
- Iris-setosa shows low variability in petal measurements, which are consistently small.
- Both Iris-versicolor and Iris-virginica exhibit more variability in their petal measurements, with Iris-virginica generally showing the largest measurements.
## CORRELATION
The correlation matrix heatmap of the Iris dataset reveals the relationships between the features. Sepal length shows a strong positive correlation with petal length (0.87) and petal width (0.82). Petal length and petal width are highly correlated (0.96), indicating that as petal length increases, petal width also tends to increase significantly. Sepal width, on the other hand, has a weak negative correlation with sepal length (-0.12) and moderate negative correlations with petal length (-0.43) and petal width (-0.37). These insights suggest that petal measurements are more strongly interrelated compared to sepal measurements, which are less correlated with each other and with petal measurements

1,908,974 | Building a Regex Generator with Gemini AI and ToolJet ⚙️ | Introduction This tutorial will guide you through the process of building an AI-powered... | 0 | 2024-07-02T13:02:20 | https://blog.tooljet.com/building-a-regex-generator-with-gemini-ai-and-tooljet/ | ## Introduction
This tutorial will guide you through the process of building an AI-powered Regex Generator using [ToolJet](https://github.com/ToolJet/ToolJet) , a low-code visual app builder, and the Gemini API, a powerful natural language processing API. The resulting application will enable users to input requests in plain English, which will then be translated into Regular Expressions (Regex). We'll use ToolJet's visual app builder to create a user-friendly UI, and ToolJet's low-code query builder to connect it to the Gemini API endpoint.
-------------------------------------------------------------
## Prerequisites:
- **ToolJet** (https://github.com/ToolJet/ToolJet ): An open-source, low-code business application builder. [Sign up](https://www.tooljet.com/signup) for a free ToolJet cloud account or [run ToolJet on your local machine](https://docs.tooljet.com/docs/setup/try-tooljet/) using Docker.
- **Gemini API Key** : Log into [Google AI Studio](https://aistudio.google.com/app/apikey) using your existing Google credentials. Within the AI Studio interface, you can locate and copy your API key.
Here is a quick preview of our final application:
Login to your [ToolJet account](https://app.tooljet.com/). Navigate to the ToolJet dashboard and click on the Create new app button on the top left corner. ToolJet comes with 45+ built-in components. This will let us set up our UI in no time.
-------------------------------------------------------------
## Assembling our UI
- Drag and drop the **Container** component onto the canvas from the component library on the right side. Adjust the height and width of the **Container** component appropriately.
- Similarly, drag-and-drop the **Icon** and **Text** component onto the canvas. We'll use them as our header.
- For the **Icon** component, navigate to the properties panel on the right and select the appropriate icon under the **Icon** property.
- Change the colour of the **Icon** and **Text** component according to your preference.
- Drag and drop one **Text** component and one **Textarea** component inside your canvas. We'll use these components for the label and input for our text query. Rename the **Textarea** component to *textQueryInput*.
- Again, drag-and-drop two **Text** components and two **Text Input** components inside your container. We'll use them for displaying the generated regex expressions and testing a string against the generated regex expression respectively.
- Rename the **Text Input** components as *generatedRegex* and *testString* respectively.
- Lastly, drag and drop two **Button** components inside your container. We'll use them for initiating the regex expression generation and adding a **copy to clipboard** functionality respectively.
- Rename the added **Button** components to *generateRegex* and *copyToClipboard* respectively.
-------------------------------------------------------------
## Setting up Queries
ToolJet allows you to connect to various external data sources, including databases, external APIs, and services using its powerful low code query builder. For this tutorial, We'll be using the REST API query feature to connect with the **Gemini** API endpoints.
- Using ToolJet's Workspace Constants feature, create a new constant named **GEMINI_API_KEY** with your Gemini API key.
- In the query panel, click on the **+ Add** button and choose the **REST API** option.
- Rename the query to *getRegexPattern.*
- In the Request parameter, choose **POST** as the Method from the drop-down and paste the following URL.
```
https://generativelanguage.googleapis.com/v1beta/models/gemini-1.5-pro:generateContent?key={{constants.GEMINI_API_KEY}}
```
Navigate to the Body section of *getRegexPattern*. Toggle on **Raw JSON** and enter the following code:
```
{{
`{
"contents": [{
"parts": [{
"text": "Text Prompt: Based on pattern, generate a regex without any code highlighting, formatting or backticks, Pattern: ${JSON.stringify(components.textQueryInput.value).replace(/\\?"/g, '\\"')}"
},],
},],
}`
}}
```
-------------------------------------------------------------
## Binding Queries to the UI Components
Now that we have successfully added our UI and the query, the next step is to integrate them.
- Select the *generateRegex* **Button** component and navigate to the properties panel on the right. Click on the **+ New event handler** button. Change the **Action** to **Run query** and select the *getRegexPattern* query. This will trigger the *getRegexPattern* every time we click the *generateRegex* button.
- Next, select the *generatedRegex* **Text Input** component and navigate to the properties panel on the right. Paste the following code into the **Default value** field:
```
{{queries.getRegexPattern.data.candidates[0].content.parts[0].text.trim()}}
```
- Select the *copyToClipboard* **Button** component and navigate to the properties panel on the right. Click on the **+ New event handler** button. Change the **Action** to **Copy to clipboard**. Paste the following code in the Text field under the Action Options subsection:
```
{{components.generatedRegex.value}}
```
- Similarly, select the *testString* **Text Input** component and navigate to the properties panel on the right. Paste the following code in the Regex field under the Validation subsection:
```
{{queries.getRegexPattern.data.candidates[0].content.parts[0].text.trim()}}
```
We have successfully integrated everything together. Now let's test the application with the text query below:
_Match any string that is at least 8 characters long, contains at least one lowercase letter, one uppercase letter, and one number_
-------------------------------------------------------------
## Conclusion
Congratulations on successfully creating an AI-powered Regex generator with ToolJet and the Gemini API. You can now input natural language prompts to generate Regular Expressions effortlessly.

I am spending hours making simplest things works.
Many commonly available features of Vanilla JS doesn't work. I am also having to find work around, most of the time the code gets unnecessary long.
The Velo API should complement Vanilla JS rather than making programming JS more difficult.
Here are some of the limitations.
* Can't select elements by className, I am having to manually type in Ids of each elements if JS was not blocked `document.querySelectorAll()` could have helped reduce unnecesary code.
<br>
* Can't create custom Events, if you need you'd be required to make custom element that works only for premium subscription.
<br>
* Touch events doesn't exist???? its 2024, more than 70% of the internet traffic comes from mobile devices. I should be able to track touch events like swipe and trigger certain actions.
<br>
* addEventListner should be readily available and we should be able to listen to other events!
That's all! thanks for listening my rant.

1,888,108 | 30 days of AWS - Part 4: AWS Storage | Welcome to part 4 of 8 of the '30 days of AWS'. Cloud storage is a critical component in cloud... | 27,709 | 2024-07-02T12:55:18 | https://dev.to/achenchi/30-days-of-aws-part-4-aws-storage-59pe | ec2, aws, ebs, efs |
**Welcome to part 4 of 8 of the '30 days of AWS'**.
Cloud storage is a critical component in cloud computing because it holds information that is accessed by your applications. Cloud storage is typically more reliable, secure, and scalable than on-premise alternatives.
AWS cloud storage offers storage options in 3 categories:
- Object storage i.e S3
- Block storage i.e EBS
- File storage i.e EFS
The most common form of storage is object storage
### Cloud storage types
#### 1. Object storage
Data is managed as individual objects.
Each object includes the data itself, the metadata, and a globally unique identifier.
The object storage service in AWS is AWS Simple Storage Service (AWS s3)
#### 2. Block storage
Block storage breaks up data into blocks and then stores those blocks as separate pieces, each with a unique identifier.
Block storage is typically more expensive than object storage and file storage but it provides the following:
- low latency
- High and consistent performance
The block storage service in AWS is the AWS Elastic Block Storage (EBS).
#### 3. File storage
In file storage, data is stored in files and the files are organized in folders, and the folders are organized under a hierarchy of directories and subdirectories.
The file storage service in AWS is the AWS Elastic File System (AWS EFS).
Let's delve deeper into each one of them.
## AWS Simple Secure Storage (s3)
Amazon s3, as mentioned earlier, is an object-level storage option.
Amazon s3 stores data within resources called **buckets **
### Amazon s3 features
- S3 is designed to deliver 99.999999999% (yap, 11 9's) durability for objects stored in the service and
- S3 supports multiple security and compliance certifications.
- You can store any type of file in s3
### Use cases of S3
**1. Backup and Disaster Recovery**
The [Cross Region Replication (CRR)](https://medium.com/@oguzhanhiziroglu/aws-s3-cross-region-replication-a-deep-dive-eb3ec1410ac7) feature in AWS s3 automatically replicates data across regions while maintaining maximum durability and availability.
Amazon S3 versioning feature, when enabled, automatically keeps multiple variants of an object in the same bucket. This makes it easier to recover these files or older versions.
**2. Big data and analytics**
S3 offers an in-place querying functionality, which is used to run analytics on data stored in S3.
**3. Content distribution**
S3 can be used to store static content, such as images, videos, and downloadable files. This content can be distributed globally to users by leveraging Amazon CloudFront, a content delivery network (CDN).
**4. Data Archiving**
Amazon S3 offers several storage class tiers, including the Amazon S3 Glacier, a durable and cost-effective archiving solution.
### AWS S3 storage classes
Amazon s3 offers 7 different storage classes that are designed for different use cases.
These classes include:
**a. Amazon S3 standard**
- it supports frequently accessed data that requires low latency and high throughput.
- It is designed for high durability, availability, and performance
- **Use cases include:** hosting dynamic websites, content distribution, mobile and gaming applications, and big data analytics.
**b. Amazon S3 Intelligent-Tiering**
- This storage class is designed to optimize costs by automatically moving data to the most cost-effective tier, without affecting performance impact.
- S3 monitors access patterns of the objects in S3 intelligent-tiering and if objects have not been accessed for 30 consecutive days, the objects are moved to the infrequent access tier (IA).
- If an object in the IA tier is accessed, it is automatically moved back to the frequent access tier.
**c. Amazon S3 standard Infrequent-Access (S3-standard-IA)**
- It is used for data that is accessed less frequently but requires rapid access when needed.
**d. Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)**
- It is used for data that is accessed less frequently but requires rapid access when needed.
- The difference between this and S3 standard IA is that S3 One Zone-IA stores data in a single availability zone.
**e. Amazon S3 Glacier Instant Retrieval**
- It is a secure, durable, and low-cost storage class for data archiving.
- This storage class can retrieve objects within a few milliseconds.
- There is a trade-off to the low-cost storage: Retrieving data from the Glacier Instant Retrieval incurs a higher cost per GB compared to the s3 standard.
**f. Amazon S3 Glacier Flexible Retrieval**
- It is a low-cost storage designed for data archiving
- This storage class retrieves objects within a few minutes to hours.
**g. Amazon S3 Glacier Deep Archive**
- This is the lowest-cost storage class for Amazon S3.
- It supports long-term retention and digital preservation of data that might be accessed once or twice a year.
- All objects stored here are replicated and stored across 3 geographically dispersed AZs.
- These objects can be restored within 12 hours.
#### Naming conventions of S3 buckets
- Names MUST be unique across all AWS accounts; within and without your organization. In other words, there aren't 2 S3 buckets that share a name in AWS.
- Names must be 3 to 63 characters in length
- Names can only contain lowercase letters, numbers, and hyphens
#### Amazon S3 pricing
You pay for what you use which includes:
- GBs per month (Storage class)
- Transfer OUTs to other regions
- PUT, COPY, POST, GET, and LIST requests
## Amazon Elastic Block Storage (EBS)
Amazon EBS provides persistent block storage volumes for use with Amazon EC2 instances.
**Persistent storage** - It is any data storage device that retains data after power to that device is shut off.
### Features of Amazon EBS
- Amazon EBS is automatically replicated within its Availability Zone.
- EBS offers consistent and low-latency performance needed to run workloads.
- EBS volume data persists independently of the life of the instance attached to it.
- You can attach multiple EBS volumes to an instance.
- EBS volumes must be in the same Availability Zone as the instances they are attached to.
A backup of an Amazon EBS is called a **snapshot**. The first snapshot is called the **baseline snapshot**
Any other snapshot after the baseline snapshot captures only what is different from the previous snapshot.
### Amazon EBS volume types
The volume types differ in performance characteristics and price.
**Volume types**
**1. Solid-state drive (SSD) volumes**
- Optimized for transactional workloads involving frequent read/write operations.
- They are usually preferred in cases where high Input/Output Operations per Second (IOPS) is required.
- SSD-backed volume types include:**General purpose SSD** and **Provisioned IOPS SSD**
**2. Hard Disk Drive (HDD)**
- Are optimized for large streaming workloads where the dominant performance attribute is throughput
**What is throughput?** - It is a measure of the amount of data transferred to and from a storage device per second.
- HDD volume types include: **Throughput optimized HDD** and **Cold HDD**
#### Use Cases of Amazon EBS
a. Boot volumes and storage for Amazon EC2 instances.
b. Database hosts
c. Data storage with a file system
## Amazon Elastic File System (EFS)
EFS provides simple, scalable, and elastic file storage for use with AWS services.
EFS uses the Network File System (NFS) protocol
**What is a Network File System (NFS) protocol?**
It is a file system protocol that allows a user on a client computer to access files over a network the same way they would access a local storage file.
Features of Amazon EFS
- It is built to dynamically scale on demand without causing disruptions.
- It is well suited for big data and analytics, web serving, media processing workflows, and home directories.
- It can scale up to petabytes
- By default, you can create up to 10 file systems per AWS account.
- It can concurrently be connected to 1 to 1000s of EC2 instances from multiple AZs.
### Use cases of EFS volumes
- Web serving and content management
- Media and entertainment
- Shared and home directories
- Database backups
- Big data analytics
### Creating an EFS
An EFS is created within an Amazon Virtual Private Cloud (VPC) and must be attached to an EC2 instance within the same VPC.
The VPC, EC2 instance, and EFS itself must all reside in the same region.
The EFS file system is mounted on the VPC using the NFS versions 4.0 and 4.1
There are 2 categories of file systems:
- **Regional file systems** - It stores data redundantly across multiple AZs. You can create a mount target in each AZ in the region.
- **One zone file systems** - It stores data redundantly within a single AZ. Only a single mount target is created.
**What is a mount target?** - IIt is an elastic network interface that 'exposes' the EFS to your VPC. Your client accesses the EFS by connecting to the mount target(s).
### Amazon EFS infrastructure
In the illustration above, the VPC spans across 3 AZs and each Availability Zone has one mount target created in it.
Accessing the file system from a mount target within the same AZ is recommended for performance and cost reasons.
One of the Availability Zones has 2 subnets. However, a mount target is created in only one of the subnets.
### Contents of the file system
**a. Mount target**
- The mount target ID
- The subnet ID for the subnet where it was created
- The file system ID
- An IP address where the file system is mounted
- The mount target state
**b. Tags**
- Key-value pair
Thank You for making it to the end 🍾🍾
See you in the next one.

1,908,972 | Paper detailing BitPower Loop’s security | Security Research of BitPower Loop BitPower Loop is a decentralized lending platform based on... | 0 | 2024-07-02T12:53:29 | https://dev.to/wgac_0f8ada999859bdd2c0e5/paper-detailing-bitpower-loops-security-58ni | Security Research of BitPower Loop
BitPower Loop is a decentralized lending platform based on blockchain technology, dedicated to providing users with safe, transparent and efficient financial services. Its core security comes from multi-level technical measures and mechanism design, which ensures the robust operation of the system and the security of user funds. This article will introduce the security of BitPower Loop in detail from five aspects: smart contract security, decentralized management, data and transaction security, fund security and risk control mechanism.
1. Smart Contract Security
Smart contracts are the core components of BitPower Loop, and their codes must undergo strict security audits before deployment. These audits are usually conducted by third-party independent security companies to ensure that there are no vulnerabilities or malicious code in the contract. In addition, the immutability of smart contracts means that once deployed, no one (including the development team) can modify its rules and logic, which fundamentally eliminates the possibility of malicious operations. All operations are automatically executed by smart contracts, avoiding the risk of human intervention and ensuring the fairness and consistency of system operation.
2. Decentralized Management
BitPower Loop eliminates the risks brought by single point failures and central control through decentralized management. The system has no central management agency or owner, and all transactions and operations are jointly verified and recorded by blockchain nodes distributed around the world. This decentralized structure not only improves the system's anti-attack capabilities, but also enhances transparency. Users can publicly view all transaction records, which increases trust in the system.
3. Data and transaction security
BitPower Loop uses advanced encryption technology to protect users' data and transaction information. All data is encrypted during transmission and storage to prevent unauthorized access and data leakage. The consensus mechanism of the blockchain ensures the validity and immutability of each transaction, eliminating the possibility of double payment and forged transactions. In addition, the automated execution of smart contracts also avoids delays and errors caused by human operations, ensuring the real-time and accuracy of transactions.
4. Fund security
The secure storage of user funds is an important feature of BitPower Loop. Funds are stored on the blockchain through smart contracts and maintained by nodes across the entire network. Distributed storage avoids the risk of fund theft caused by centralized storage. In addition, the user's investment returns and shared commissions are automatically allocated to the user's wallet address by the smart contract after the conditions are met, ensuring the timely and accurate arrival of funds.
5. Risk Control Mechanism
BitPower Loop effectively manages lending risks by setting collateral factors and liquidation mechanisms. The collateral factors are independently set according to market liquidity and asset value fluctuations to ensure system stability and lending security. When the value of the borrower's assets falls below a certain threshold, the liquidation mechanism is automatically triggered, ensuring the repayment of the borrower's debt and protecting the interests of the fund provider. In addition, the immutability and automatic execution characteristics of smart contracts further enhance the security and reliability of the system.
Conclusion
BitPower Loop achieves high security and stability through multi-level security measures and mechanism design. Its smart contracts are strictly audited and immutable, decentralized management eliminates single point failure risks, advanced encryption technology protects data and transaction security, distributed storage ensures fund security, and risk control mechanisms manage lending risks. These security features together build a reliable decentralized financial platform that provides users with secure, transparent and efficient financial services.

1,908,965 | Terraform Validate Command: Practical Examples and Best Practices | What is Terraform Validate The validate command helps you make sure your Terraform (or... | 0 | 2024-07-02T12:46:17 | https://www.env0.com/blog/terraform-validate-command-practical-examples-and-best-practices | terraform, cloud, devops, infrastructureascode | What is Terraform Validate
--------------------------
The `validate` command helps you make sure your [Terraform](https://www.env0.com/blog/what-is-terraform-cli) (or [OpenTofu](https://www.env0.com/blog/opentofu-the-open-source-terraform-alternative)) code is syntactically correct before you deploy. This helps you to prevent misconfiguration due to missing attributes or incorrect dependencies, saving time, improving efficiency, and reducing cost.
Under the hood, `terraform validate` performs these actions:
* **Validates that the syntax of the terraform files is correct -** For example, if you want to use the terraform ternary function in your code and provide the incorrect syntax halfway, terraform can capture it and help you fix it.
* **Verifies the consistency of the terraform configuration** -For instance, whether the value of the terraform variable matches the validation block defined for that variable.
* **Performs static analysis of the configuration file** - For example, it checks whether all required fields for a resource are provided without accessing remote modules or the current state of infrastructure (without accessing any external network).
In this post, we will cover the following:
1. How is the `terraform validate` useful
2. How should you validate different file types - single file, multiple files, or modules
3. What are the different ways you can run `terraform validate` locally
4. How can you use env0 to run `terraform validate`
> **Disclaimer
> **All use cases of 'terraform validate' discussed here work similarly in OpenTofu, the open-source Terraform alternative. However, to keep thing simple and familiar, we will refer to 'terraform validate' throughout this discussion from now on.
**How to use Terraform Validate**
----------------------------------
You can run `terraform validate` within a directory that contains a single configuration file, multiple configuration files, or modules at different stages of your infrastructure development.
Let us do a hands-on demonstration to see how different running the `terraform validate` for each scenario can be.
### **Run Terraform Validate Locally for Multiple Files**
We will create a bucket in the Google Cloud Platform (GCP) using the Terraform configuration.
Download the Google Cloud CLI on your machine and configure your directory to use the GCP project. Run this command in your terminal for the current working directory:
gcloud config set project validate-project-425602
Set your provider in the **provider.tf** file with the project name.
provider "google" {
project = "validate-project-425602"
}
In the **main. tf** file, create a bucket with the default configuration. To create a unique bucket name, we will create and pass the random ID using the random\_id resource block:
resource "random_id" "bucket_id" {
byte_length = 4
}
resource "google_storage_bucket" "bucket" {
name = "bucket_${random_id.bucket_id.hex}"
storage_class = "STANDARD"
labels = {
name = "nonprod-bucket"
team = "engineering"
}
}
Go to the current working directory in your terminal and run the `terraform validate` command.
You will catch syntax errors in your configuration files before deploying your infrastructure. This will save you time and prevent you from messing up your infrastructure on cloud platforms like Azure, AWS, and GCP.
If you have this bucket as a dependency, Terraform might attempt to create resources in the wrong order, leading to errors or incomplete infrastructure setups.
As an output, you will get the missing argument error message:
You need to fix this error by adding the location to your `google_storage_bucket` resource and run `terraform validate` again.
If you do not add the location and try to deploy the bucket, it will fail with the same error message or lead to resource misconfigurations during deployment.
Once you have added the location, the output will display that the configuration is valid:
Use of Flags in Terraform Validate
----------------------------------
You can use flags to help improve the output of `terraform validate`. Here are some instances of how you can use these in the above example.
* **\-json** flag: Produces output in a machine-readable JSON format without color. It is useful in text editor integrations. The diagnostics array of nested JSON objects provides more details of the errors, which will help you identify exactly where you can find the particular error in your code.
* **\-no-color** flag: Disables the color output in the terminal. It is useful when the output is piped to another command or written to a file where color codes are inappropriate or difficult to read.
**Potential Issues Solved by Terraform Validate**
-------------------------------------------------
Let us look at the few scenarios taken care of by the `terraform validate` command:
* It checks if the variable interpolation is correct and consistent with HCL.
* It analyzes if the data passed to an attribute matches its desired data type.
* It runs checks to verify if all the mandatory attributes are present for the resource or data block.
* If you have [input variables](https://www.env0.com/blog/terraform-variables) declared by setting default values and custom validation rules and handling undeclared variables in Terraform configurations, they are validated against the multiple validation blocks.
**Practical Examples**
----------------------
Now that we have defined the basics for `terraform validate`, let's review some of the more advanced ways in which the command can be used:
#### **Running Terraform Validate as a Pre-Commit Hook for a Single File**
You might have all your configurations in one **main.tf** file and want to ensure that you do not push any syntactically incorrect code to a version control system like git.
To do this, you can run `terraform validate` as a pre-commit hook.
Configure your pre-commit hook by creating a **pre-commit** file in the **.github/hooks** folder of your project to run `terraform init` and `terraform validate`.
You will get an error if the configuration is invalid. The code for the pre-commit hook file looks like this:
#!/bin/bash
TERRAFORM_DIR="path/to/your/terraform/directory"
cd "$TERRAFORM_DIR" || exit 1
terraform init -backend=false -input=false
terraform validate
EXIT_CODE=$?
if [ $EXIT_CODE -ne 0 ]; then
echo "Terraform validation failed. Please fix the issues and try again."
exit $EXIT_CODE
fi
exit 0
Make this file executable by running this command in your current working directory:
chmod +x .git/hooks/pre-commit
The pre-commit script will run when you make changes to the **main.tf** file and create a commit.
The Terraform configuration in your **main.tf** file will be validated, and you will get the following output:
#### **Running Terraform Validate for Modules**
To validate the [Terraform module](https://www.env0.com/blog/terraform-modules) configuration, navigate to the module directory and run `terraform validate`.
For example, if a module named `iam-role` is configured incorrectly when `terraform validate` is run in the terminal inside the module, it will output an error message like the one below:
If you do not fix this issue, Terraform may fail to apply the module configurations correctly, leading to incomplete or incorrect resource setups in your infrastructure.
#### **Running the Validate Command in a Workflow**
The infrastructure code with syntax errors is unreliable and inconsistent, causing deployment issues.
Running `terraform validate` frequently is essential during and after the initial stages of development. It will help prevent any syntax errors and allow you to get a valid configuration.
When you run `terraform validate` locally, sometimes, you might forget to run the `terraform validate` command locally with frequent changes.
When that happens, you must include it as part of the CI/CD pipelines to achieve uniformity.
You should make this a standard practice in your team or organization by using [env0](https://www.env0.com/) to run `terraform validate` as part of your CI/CD pipeline.
This will give you a consistent, easily scalable environment across multiple projects and team members, centralize and streamline workflows, and enhance compliance and audibility.
**Integrating Terraform Validation with env0**
----------------------------------------------
With [env0](https://www.env0.com/)’s [ad-hoc tasks](https://www.env0.com/blog/ad-hoc-tasks) feature, every Terraform command is tracked, allowing your team to see who ran the `terraform validation` command and when it was executed.
One way this feature can be used is to automatically run `terraform validate` as part of your CI/CD pipeline, ensuring all Terraform configurations are syntactically correct before deployment.
By integrating it with VCS, env0 allows multiple team members to collaborate on Terraform configurations, with automatic validation to catch errors early.
For example, here is how you can use env0’s ad-hoc feature to create a Storage Bucket from GCP into our Terraform configuration to streamline the validation process.
First, push the Terraform configuration files to the GitHub repository, where you will create a storage bucket resource:
resource "google_storage_bucket" "bucket-name" {
name = "bucket_${random_id.bucket_id.hex}"
location = "US"
storage_class = "STANDARD"
labels = {
name = "prod-bucket"
}
}
Next, integrate this GitHub repository with [env0](https://www.env0.com/). For that, simply add a `terraform validate` command to your env0 workflow as an ad-hoc task:
In the [env0](https://www.env0.com/) console you will see the task running with the output:
And that's it! You have successfully validated your Terraform configuration for the GCP bucket, allowing you to auto-run syntax checks and validation within env0, as part of your CI/CD pipeline.
**Wrapping up**
----------------
The `Terraform validate` command is your go-to tool for ensuring your Terraform configurations are correct and consistent before deployment.
Whether running `terraform validate` locally or integrating it into your CI/CD pipelines with env0, `terraform validate` helps you get early feedback and save time.
Including `terraform validate` with [`terraform plan`](https://www.env0.com/blog/terraform-plan) and [`terraform apply`](https://www.env0.com/blog/terraform-apply-guide-command-options-and-examples) in your env0 workflows makes your processes reliable, efficient, and scalable.
**FAQ’s**
---------
#### **Q: What is the difference between terraform validate and terraform fmt?**
The two Terraform commands – `terraform validate` and `terraform fmt` – are used to maintain a clean, error-free, and well-structured Terraform codebase.
Let's quickly compare the two here:
#### **Q: How do you validate variables in Terraform?**

1,908,958 | Paper detailing BitPower Loop’s security | Security Research of BitPower Loop BitPower Loop is a decentralized lending platform based on... | 0 | 2024-07-02T12:41:12 | https://dev.to/weq_24a494dd3a467ace6aca5/paper-detailing-bitpower-loops-security-4gka | Security Research of BitPower Loop
BitPower Loop is a decentralized lending platform based on blockchain technology, dedicated to providing users with safe, transparent and efficient financial services. Its core security comes from multi-level technical measures and mechanism design, which ensures the robust operation of the system and the security of user funds. This article will introduce the security of BitPower Loop in detail from five aspects: smart contract security, decentralized management, data and transaction security, fund security and risk control mechanism.
1. Smart Contract Security
Smart contracts are the core components of BitPower Loop, and their codes must undergo strict security audits before deployment. These audits are usually conducted by third-party independent security companies to ensure that there are no vulnerabilities or malicious code in the contract. In addition, the immutability of smart contracts means that once deployed, no one (including the development team) can modify its rules and logic, which fundamentally eliminates the possibility of malicious operations. All operations are automatically executed by smart contracts, avoiding the risk of human intervention and ensuring the fairness and consistency of system operation.
2. Decentralized Management
BitPower Loop eliminates the risks brought by single point failures and central control through decentralized management. The system has no central management agency or owner, and all transactions and operations are jointly verified and recorded by blockchain nodes distributed around the world. This decentralized structure not only improves the system's anti-attack capabilities, but also enhances transparency. Users can publicly view all transaction records, which increases trust in the system.
3. Data and transaction security
BitPower Loop uses advanced encryption technology to protect users' data and transaction information. All data is encrypted during transmission and storage to prevent unauthorized access and data leakage. The consensus mechanism of the blockchain ensures the validity and immutability of each transaction, eliminating the possibility of double payment and forged transactions. In addition, the automated execution of smart contracts also avoids delays and errors caused by human operations, ensuring the real-time and accuracy of transactions.
4. Fund security
The secure storage of user funds is an important feature of BitPower Loop. Funds are stored on the blockchain through smart contracts and maintained by nodes across the entire network. Distributed storage avoids the risk of fund theft caused by centralized storage. In addition, the user's investment returns and shared commissions are automatically allocated to the user's wallet address by the smart contract after the conditions are met, ensuring the timely and accurate arrival of funds.
5. Risk Control Mechanism
BitPower Loop effectively manages lending risks by setting collateral factors and liquidation mechanisms. The collateral factors are independently set according to market liquidity and asset value fluctuations to ensure system stability and lending security. When the value of the borrower's assets falls below a certain threshold, the liquidation mechanism is automatically triggered, ensuring the repayment of the borrower's debt and protecting the interests of the fund provider. In addition, the immutability and automatic execution characteristics of smart contracts further enhance the security and reliability of the system.
Conclusion
BitPower Loop achieves high security and stability through multi-level security measures and mechanism design. Its smart contracts are strictly audited and immutable, decentralized management eliminates single point failure risks, advanced encryption technology protects data and transaction security, distributed storage ensures fund security, and risk control mechanisms manage lending risks. These security features together build a reliable decentralized financial platform that provides users with secure, transparent and efficient financial services.

1,908,957 | APIs vs. Endpoints: Breaking Down the Differences | Despite being basic ideas in web development and programming, APIs and endpoints can lead to... | 0 | 2024-07-02T12:39:44 | https://www.nilebits.com/blog/2024/07/apis-vs-endpoints-breaking-down-differences/ | api, endpoints, apigateway, python | Despite being basic ideas in web development and programming, APIs and endpoints can lead to misunderstanding. These phrases have different meanings and purposes, despite their close relationship and sometimes interchange, which leads to misunderstanding. This blog article will go over APIs and endpoints in detail, explain how they vary, and provide you many of code samples to help you understand.
Introduction to APIs
Application Programming Interface is referred to as API. It is a system of guidelines and procedures that enables various software programs to speak with one another. Through endpoints, an API exposes data or functionality and specifies the proper method by which a developer may request services from an operating system or other applications.
APIs are used in various contexts:
Web APIs: Enable communication between a web server and a client.
Operating System APIs: Allow applications to use resources of the operating system.
Library APIs: Provide access to the functions of software libraries.
Example: Web API
Consider a simple web API that provides data about books. This API could allow clients to fetch a list of books, add a new book, update book details, or delete a book.
```
# Example of a simple Web API using Flask (Python)
from flask import Flask, jsonify, request
app = Flask(__name__)
books = [
{'id': 1, 'title': '1984', 'author': 'George Orwell'},
{'id': 2, 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee'}
]
@app.route('/books', methods=['GET'])
def get_books():
return jsonify(books)
@app.route('/books', methods=['POST'])
def add_book():
new_book = request.get_json()
books.append(new_book)
return jsonify(new_book), 201
@app.route('/books/<int:id>', methods=['PUT'])
def update_book(id):
book = next((b for b in books if b['id'] == id), None)
if book is None:
return jsonify({'error': 'Book not found'}), 404
data = request.get_json()
book.update(data)
return jsonify(book)
@app.route('/books/<int:id>', methods=['DELETE'])
def delete_book(id):
global books
books = [b for b in books if b['id'] != id]
return '', 204
if __name__ == '__main__':
app.run(debug=True)
```
In this example, the API defines several endpoints (routes) for managing books. Each endpoint allows clients to perform specific operations on the books resource.
What are Endpoints?
An endpoint is a specific URL pattern at which a particular service is made available. It represents one end of a communication channel, often corresponding to an operation exposed by the API.
Endpoints are crucial components of APIs. They define where and how resources can be accessed or manipulated.
Example: Endpoints in a Web API
Continuing with the previous example, let's identify the endpoints:
GET /books: Fetches a list of all books.
POST /books: Adds a new book.
PUT /books/<int:id>: Updates the book with the specified ID.
DELETE /books/<int:id>: Deletes the book with the specified ID.
Each of these endpoints performs a different operation, allowing clients to interact with the books resource in specific ways.
Key Differences Between APIs and Endpoints
Scope:
API: An API is a broader concept encompassing a set of rules and definitions for building and integrating software applications. It includes multiple endpoints.
Endpoint: An endpoint is a specific URL pattern within an API that performs a particular function.
Functionality:
API: An API defines how different software components should interact. It provides a complete interface for accessing the features and data of an application.
Endpoint: An endpoint is the specific point of interaction within the API where an operation is performed.
Structure:
API: An API is composed of multiple endpoints, each handling a specific part of the application's functionality.
Endpoint: An endpoint is a single point within the API that corresponds to a particular operation.
Detailed Code Examples
To further illustrate the differences and interactions between APIs and endpoints, let's expand our previous example. We will add more functionalities and show how endpoints work within the broader context of an API.
Adding Authentication
Let's add authentication to our API. Only authenticated users should be able to add, update, or delete books.
```
from flask import Flask, jsonify, request, abort
app = Flask(__name__)
books = [
{'id': 1, 'title': '1984', 'author': 'George Orwell'},
{'id': 2, 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee'}
]
users = {
'user1': 'password1',
'user2': 'password2'
}
def authenticate():
auth = request.authorization
if not auth or not users.get(auth.username) == auth.password:
return False
return True
@app.route('/books', methods=['GET'])
def get_books():
return jsonify(books)
@app.route('/books', methods=['POST'])
def add_book():
if not authenticate():
return jsonify({'error': 'Unauthorized access'}), 401
new_book = request.get_json()
books.append(new_book)
return jsonify(new_book), 201
@app.route('/books/<int:id>', methods=['PUT'])
def update_book(id):
if not authenticate():
return jsonify({'error': 'Unauthorized access'}), 401
book = next((b for b in books if b['id'] == id), None)
if book is None:
return jsonify({'error': 'Book not found'}), 404
data = request.get_json()
book.update(data)
return jsonify(book)
@app.route('/books/<int:id>', methods=['DELETE'])
def delete_book(id):
if not authenticate():
return jsonify({'error': 'Unauthorized access'}), 401
global books
books = [b for b in books if b['id'] != id]
return '', 204
if __name__ == '__main__':
app.run(debug=True)
In this example, the authenticate function checks if the request contains valid authentication credentials. The POST, PUT, and DELETE endpoints are protected, requiring valid credentials to access.
Adding Error Handling
Let's improve our API by adding more detailed error handling. This ensures that clients receive meaningful error messages when something goes wrong.
from flask import Flask, jsonify, request, abort
app = Flask(__name__)
books = [
{'id': 1, 'title': '1984', 'author': 'George Orwell'},
{'id': 2, 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee'}
]
users = {
'user1': 'password1',
'user2': 'password2'
}
def authenticate():
auth = request.authorization
if not auth or not users.get(auth.username) == auth.password:
return False
return True
@app.errorhandler(400)
def bad_request(error):
return jsonify({'error': 'Bad request'}), 400
@app.errorhandler(401)
def unauthorized(error):
return jsonify({'error': 'Unauthorized access'}), 401
@app.errorhandler(404)
def not_found(error):
return jsonify({'error': 'Resource not found'}), 404
@app.route('/books', methods=['GET'])
def get_books():
return jsonify(books)
@app.route('/books', methods=['POST'])
def add_book():
if not authenticate():
abort(401)
if not request.json or not 'title' in request.json:
abort(400)
new_book = {
'id': books[-1]['id'] + 1 if books else 1,
'title': request.json['title'],
'author': request.json.get('author', "")
}
books.append(new_book)
return jsonify(new_book), 201
@app.route('/books/<int:id>', methods=['PUT'])
def update_book(id):
if not authenticate():
abort(401)
book = next((b for b in books if b['id'] == id), None)
if book is None:
abort(404)
if not request.json:
abort(400)
book['title'] = request.json.get('title', book['title'])
book['author'] = request.json.get('author', book['author'])
return jsonify(book)
@app.route('/books/<int:id>', methods=['DELETE'])
def delete_book(id):
if not authenticate():
abort(401)
global books
books = [b for b in books if b['id'] != id]
return '', 204
if __name__ == '__main__':
app.run(debug=True)
```
In this improved version, we added custom error handlers for different HTTP status codes. The abort function is used to trigger these error handlers when necessary, providing more informative error messages to clients.
Advanced Concepts: Versioning and Rate Limiting
As APIs grow in complexity, it becomes essential to manage different versions and limit the rate of requests to ensure stability and backward compatibility.
API Versioning
API versioning allows you to maintain different versions of your API to support legacy clients while adding new features for newer clients. Let's add versioning to our API.
```
from flask import Flask, jsonify, request, abort
app = Flask(__name__)
books_v1 = [
{'id': 1, 'title': '1984', 'author': 'George Orwell'},
{'
id': 2, 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee'}
]
books_v2 = [
{'id': 1, 'title': '1984', 'author': 'George Orwell', 'published': '1949'},
{'id': 2, 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee', 'published': '1960'}
]
users = {
'user1': 'password1',
'user2': 'password2'
}
def authenticate():
auth = request.authorization
if not auth or not users.get(auth.username) == auth.password:
return False
return True
@app.route('/v1/books', methods=['GET'])
def get_books_v1():
return jsonify(books_v1)
@app.route('/v1/books', methods=['POST'])
def add_book_v1():
if not authenticate():
abort(401)
if not request.json or not 'title' in request.json:
abort(400)
new_book = {
'id': books_v1[-1]['id'] + 1 if books_v1 else 1,
'title': request.json['title'],
'author': request.json.get('author', "")
}
books_v1.append(new_book)
return jsonify(new_book), 201
@app.route('/v1/books/<int:id>', methods=['PUT'])
def update_book_v1(id):
if not authenticate():
abort(401)
book = next((b for b in books_v1 if b['id'] == id), None)
if book is None:
abort(404)
if not request.json:
abort(400)
book['title'] = request.json.get('title', book['title'])
book['author'] = request.json.get('author', book['author'])
return jsonify(book)
@app.route('/v1/books/<int:id>', methods=['DELETE'])
def delete_book_v1(id):
if not authenticate():
abort(401)
global books_v1
books_v1 = [b for b in books_v1 if b['id'] != id]
return '', 204
@app.route('/v2/books', methods=['GET'])
def get_books_v2():
return jsonify(books_v2)
@app.route('/v2/books', methods=['POST'])
def add_book_v2():
if not authenticate():
abort(401)
if not request.json or not 'title' in request.json:
abort(400)
new_book = {
'id': books_v2[-1]['id'] + 1 if books_v2 else 1,
'title': request.json['title'],
'author': request.json.get('author', ""),
'published': request.json.get('published', "")
}
books_v2.append(new_book)
return jsonify(new_book), 201
@app.route('/v2/books/<int:id>', methods=['PUT'])
def update_book_v2(id):
if not authenticate():
abort(401)
book = next((b for b in books_v2 if b['id'] == id), None)
if book is None:
abort(404)
if not request.json:
abort(400)
book['title'] = request.json.get('title', book['title'])
book['author'] = request.json.get('author', book['author'])
book['published'] = request.json.get('published', book['published'])
return jsonify(book)
@app.route('/v2/books/<int:id>', methods=['DELETE'])
def delete_book_v2(id):
if not authenticate():
abort(401)
global books_v2
books_v2 = [b for b in books_v2 if b['id'] != id]
return '', 204
if __name__ == '__main__':
app.run(debug=True)
```
In this example, we created two versions of the API (v1 and v2). Each version has its own set of endpoints, allowing clients to choose which version to interact with. This approach helps maintain backward compatibility while enabling the introduction of new features and improvements.
Rate Limiting
Rate restriction sets a cap on how many requests a client may make to an API in a certain amount of time. Fair usage among clients is ensured and abuse is prevented. Let's use the flask-limiter extension to provide rate restriction for our API.
```
from flask import Flask, jsonify, request, abort
from flask_limiter import Limiter
from flask_limiter.util import get_remote_address
app = Flask(__name__)
limiter = Limiter(
get_remote_address,
app=app,
default_limits=["200 per day", "50 per hour"]
)
books = [
{'id': 1, 'title': '1984', 'author': 'George Orwell'},
{'id': 2, 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee'}
]
users = {
'user1': 'password1',
'user2': 'password2'
}
def authenticate():
auth = request.authorization
if not auth or not users.get(auth.username) == auth.password:
return False
return True
@app.errorhandler(400)
def bad_request(error):
return jsonify({'error': 'Bad request'}), 400
@app.errorhandler(401)
def unauthorized(error):
return jsonify({'error': 'Unauthorized access'}), 401
@app.errorhandler(404)
def not_found(error):
return jsonify({'error': 'Resource not found'}), 404
@app.errorhandler(429)
def ratelimit_error(error):
return jsonify({'error': 'Too many requests'}), 429
@app.route('/books', methods=['GET'])
@limiter.limit("10 per minute")
def get_books():
return jsonify(books)
@app.route('/books', methods=['POST'])
@limiter.limit("5 per minute")
def add_book():
if not authenticate():
abort(401)
if not request.json or not 'title' in request.json:
abort(400)
new_book = {
'id': books[-1]['id'] + 1 if books else 1,
'title': request.json['title'],
'author': request.json.get('author', "")
}
books.append(new_book)
return jsonify(new_book), 201
@app.route('/books/<int:id>', methods=['PUT'])
@limiter.limit("5 per minute")
def update_book(id):
if not authenticate():
abort(401)
book = next((b for b in books if b['id'] == id), None)
if book is None:
abort(404)
if not request.json:
abort(400)
book['title'] = request.json.get('title', book['title'])
book['author'] = request.json.get('author', book['author'])
return jsonify(book)
@app.route('/books/<int:id>', methods=['DELETE'])
@limiter.limit("5 per minute")
def delete_book(id):
if not authenticate():
abort(401)
global books
books = [b for b in books if b['id'] != id]
return '', 204
if __name__ == '__main__':
app.run(debug=True)
```
In this example, the flask-limiter extension is used to apply rate limits to different endpoints. The default_limits parameter sets global rate limits, while the @limiter.limit decorator applies specific rate limits to individual endpoints. If a client exceeds the allowed number of requests, they receive a 429 Too Many Requests error.
Best Practices for Designing APIs and Endpoints
Consistency:
Ensure that your API endpoints follow a consistent naming convention and structure. This makes it easier for clients to understand and use your API.
Versioning:
Use versioning to manage changes and improvements to your API without breaking existing clients. Prefer URL-based versioning (e.g., /v1/resource) for clarity.
Documentation:
Provide comprehensive and up-to-date documentation for your API. Include information about available endpoints, request/response formats, authentication methods, and error handling.
Error Handling:
Implement meaningful error messages and appropriate HTTP status codes. This helps clients understand what went wrong and how to fix it.
Security:
Use authentication and authorization mechanisms to protect your API. Ensure that sensitive data is transmitted securely using HTTPS.
Rate Limiting:
Implement rate limiting to prevent abuse and ensure fair usage. Customize rate limits based on the needs of your API and clients.
Testing:
Thoroughly test your API to ensure it works as expected. Use automated testing tools to cover various scenarios and edge cases.
Monitoring:
Monitor your API to detect and resolve issues promptly. Use logging and monitoring tools to track performance, errors, and usage patterns.
Conclusion
APIs and endpoints are fundamental concepts in web development, each playing a distinct role in enabling communication between software applications. Understanding the differences between APIs and endpoints is crucial for designing robust and efficient systems.
In this blog post, we explored the concepts of APIs and endpoints, highlighted their differences, and provided detailed code examples to illustrate their usage. We also discussed advanced topics like versioning and rate limiting, along with best practices for designing APIs.

With the development of blockchain technology, decentralized finance (DeFi) as a new financial model has gradually attracted widespread attention. As a member of the DeFi field, BitPower has demonstrated the potential of decentralized finance through its unique smart contract mechanism, income structure and security measures. This article will explore the rationality of BitPower mechanism and analyze its advantages in security, profitability and sustainability.
Security of smart contracts
The core of BitPower lies in its smart contracts, which are deployed on the Ethereum Virtual Machine (EVM) and based on TRC20 and ERC20 standards. The code of these smart contracts is open source, ensuring the transparency and credibility of the system. Due to the immutability of smart contracts, they cannot be modified or deleted once deployed, which greatly improves the security and stability of the system. In addition, BitPower Loop adopts a completely decentralized operation mode, without centralized administrators or owners, which means that no one can unilaterally change the system rules, thus avoiding human intervention and operational risks.
Rationality of income structure
BitPower's income structure is cleverly designed to encourage users to get returns by providing liquidity. Users can provide liquidity according to different time periods and obtain corresponding yields. For example, the annualized yields of 1 day, 7 days, 14 days and 28 days are 429%, 773%, 1065% and 1638% respectively. This structure not only encourages users to participate in short-term investment, but also provides considerable returns for long-term investment. At the same time, the introduction of the compound interest mechanism further enhances the observability of the returns, so that the user's investment returns can grow significantly over time.
Sustainability of the promotion mechanism
BitPower's promotion mechanism aims to expand the user base by inviting new users to join, thereby enhancing the liquidity and stability of the system. Each user can become a project initiator, invite new users to join through an invitation link, and receive corresponding referral rewards. The referral reward varies according to the level of the referral, ranging from 20% of the first-generation friends to 1% of the 17th-generation friends. This hierarchical referral reward mechanism not only encourages users to actively promote, but also ensures the long-term sustainable development of the system.
Decentralized governance structure
BitPower's decentralized governance structure is another important manifestation of the rationality of its mechanism. The system has no centralized manager, and all participants are equal in rules and mechanisms. This decentralized governance structure ensures the fairness and transparency of the system and avoids possible corruption and injustice in the centralized system. At the same time, decentralized governance also enhances the resilience of the system, enabling it to better cope with external attacks and internal problems.
Rationality of the economic model
BitPower's economic model is reasonably designed and can effectively balance the benefits and risks of the system. Users' benefits mainly come from liquidity provision and recommendation rewards. This income structure avoids high-risk models such as Ponzi schemes while maintaining high returns. In addition, BitPower also automatically executes reward distribution through smart contracts, reducing the risks and errors of human operations and improving the efficiency and reliability of the system.
Summary
Through the analysis of the BitPower mechanism, it can be seen that it has significant advantages in security, profitability and sustainability. The immutability of smart contracts and the decentralized governance structure ensure the security and fairness of the system; the reasonable income structure and promotion mechanism provide users with considerable returns while enhancing the liquidity and stability of the system; the design of the economic model effectively balances benefits and risks. In summary, BitPower's mechanism is highly reasonable and feasible in the current DeFi field, providing a powerful example for the development of decentralized finance.
Future Outlook
With the continuous development of blockchain technology and DeFi ecology, BitPower is expected to play a greater role in the future. By continuously optimizing smart contracts and improving user experience, BitPower can attract more users to join and further expand its influence and market share. At the same time, with the introduction of more innovative mechanisms, BitPower is expected to make more breakthroughs in the field of decentralized finance and provide users with richer and more diverse financial services.
In short, as a decentralized financial platform, BitPower's reasonable mechanism design not only ensures the security and stability of the system, but also provides users with generous returns and continuous incentives. It is an important case worthy of attention and research in the DeFi field.

With the development of blockchain technology, decentralized finance (DeFi) as a new financial model has gradually attracted widespread attention. As a member of the DeFi field, BitPower has demonstrated the potential of decentralized finance through its unique smart contract mechanism, income structure and security measures. This article will explore the rationality of BitPower mechanism and analyze its advantages in security, profitability and sustainability.
Security of smart contracts
The core of BitPower lies in its smart contracts, which are deployed on the Ethereum Virtual Machine (EVM) and based on TRC20 and ERC20 standards. The code of these smart contracts is open source, ensuring the transparency and credibility of the system. Due to the immutability of smart contracts, they cannot be modified or deleted once deployed, which greatly improves the security and stability of the system. In addition, BitPower Loop adopts a completely decentralized operation mode, without centralized administrators or owners, which means that no one can unilaterally change the system rules, thus avoiding human intervention and operational risks.
Rationality of income structure
BitPower's income structure is cleverly designed to encourage users to get returns by providing liquidity. Users can provide liquidity according to different time periods and obtain corresponding yields. For example, the annualized yields of 1 day, 7 days, 14 days and 28 days are 429%, 773%, 1065% and 1638% respectively. This structure not only encourages users to participate in short-term investment, but also provides considerable returns for long-term investment. At the same time, the introduction of the compound interest mechanism further enhances the observability of the returns, so that the user's investment returns can grow significantly over time.
Sustainability of the promotion mechanism
BitPower's promotion mechanism aims to expand the user base by inviting new users to join, thereby enhancing the liquidity and stability of the system. Each user can become a project initiator, invite new users to join through an invitation link, and receive corresponding referral rewards. The referral reward varies according to the level of the referral, ranging from 20% of the first-generation friends to 1% of the 17th-generation friends. This hierarchical referral reward mechanism not only encourages users to actively promote, but also ensures the long-term sustainable development of the system.
Decentralized governance structure
BitPower's decentralized governance structure is another important manifestation of the rationality of its mechanism. The system has no centralized manager, and all participants are equal in rules and mechanisms. This decentralized governance structure ensures the fairness and transparency of the system and avoids possible corruption and injustice in the centralized system. At the same time, decentralized governance also enhances the resilience of the system, enabling it to better cope with external attacks and internal problems.
Rationality of the economic model
BitPower's economic model is reasonably designed and can effectively balance the benefits and risks of the system. Users' benefits mainly come from liquidity provision and recommendation rewards. This income structure avoids high-risk models such as Ponzi schemes while maintaining high returns. In addition, BitPower also automatically executes reward distribution through smart contracts, reducing the risks and errors of human operations and improving the efficiency and reliability of the system.
Summary
Through the analysis of the BitPower mechanism, it can be seen that it has significant advantages in security, profitability and sustainability. The immutability of smart contracts and the decentralized governance structure ensure the security and fairness of the system; the reasonable income structure and promotion mechanism provide users with considerable returns while enhancing the liquidity and stability of the system; the design of the economic model effectively balances benefits and risks. In summary, BitPower's mechanism is highly reasonable and feasible in the current DeFi field, providing a powerful example for the development of decentralized finance.
Future Outlook
With the continuous development of blockchain technology and DeFi ecology, BitPower is expected to play a greater role in the future. By continuously optimizing smart contracts and improving user experience, BitPower can attract more users to join and further expand its influence and market share. At the same time, with the introduction of more innovative mechanisms, BitPower is expected to make more breakthroughs in the field of decentralized finance and provide users with richer and more diverse financial services.
In short, as a decentralized financial platform, BitPower's reasonable mechanism design not only ensures the security and stability of the system, but also provides users with generous returns and continuous incentives. It is an important case worthy of attention and research in the DeFi field.

In this article, I will guide you on creating a bash script that can be used to automate the creation of users and groups based on a provided list, set up home directories, generate random passwords and log all actions in a log file.
This script is task 2 given as part of the HNG Internship: DevOps track. You can read more about the HNG program [here](https://hng.tech/internship), and if you are hiring talented developers, checkout their services [here](https://hng.tech/hire).

## Introduction
This script automates user and group creation on a Unix-based system, making it easier for SysOps engineers to manage multiple users.
It reads a list of usernames and their respective groups from a file, creates users and groups, sets up home directories with appropriate permissions, generates random passwords, and logs all actions.
## Prerequisities
- Basic knowledge of Linux commands and Bash scripting.
- **Root or sudo** privileges to run the script.
- An input file containing the list of users and groups formatted as `username;group1,group2,...`
e.g.
```
flash; sudo,dev,www-data
thunder; sudo
thanos; dev,www-data
```
## Script Overview
### Shebang
When writing a bash script, the first thing is to ensure that you include a shebang at the top of the script file.
Shebang is used to tell the system which interpreter/command to use to execute the commands written inside the scripts.
For example in this case, let's use `#!/bin/bash` to tell the terminal to use bash to execute the script.
You can read more about shebang [here](https://medium.com/@codingmaths/bin-bash-what-exactly-is-this-95fc8db817bf).
### File Paths
We need to set variables that specifies/stores paths to the files we will be using to achieve the various tasks.
This files are:
- **LOG_FILE**: The log file where all actions are recorded.
- **PASSWORD_FILE**: The file where generated passwords are stored securely.
```sh
LOG_FILE="/var/log/user_management.log"
PASSWORD_FILE="/var/secure/user_passwords.txt"
```
### Ensure Secure Directory Exists
We use the conditional if statement to ensure that the `var/secure` directory exist.
```sh
if ! mkdir -p /var/secure 2>/dev/null; then
echo "Failed to create /var/secure directory. Permission denied."
exit 1
fi
chmod 700 /var/secure
```
`chmod 700` grants the owner read , write and execute permissions, and gives no permissions for group and other users.
### Clear Log and Password Files
This step clears the log and password files if they exist and sets appropriate permissions.
```sh
> "$LOG_FILE" 2>/dev/null || { echo "Failed to create log file $LOG_FILE. Permission denied."; exit 1; }
> "$PASSWORD_FILE" 2>/dev/null || { echo "Failed to create password file $PASSWORD_FILE. Permission denied."; exit 1; }
chmod 600 "$PASSWORD_FILE"
```
`chmod 600` grants read and write permissions to the owner, while denying all permissions to the group and other users.
You can read more about modifying file permissions with chmod [here](https://www.linode.com/docs/guides/modify-file-permissions-with-chmod/).
### Generate Random Password
This function creates a random 12-character password.
```sh
generate_password() {
tr -dc A-Za-z0-9 </dev/urandom | head -c 12
}
```
### Check Input File
Here, we check if an input file that contains a list of users and groups is provided and exits with a usage message if not.
```sh
if [ -z "$1" ]; then
echo "Usage: $0 <user_list_file>"
exit 1
fi
```
### Read the input file line by line
Once we have verified that an input file has been provided, we can now process each user in the input file.
```sh
while IFS=';' read -r username groups; do
```
To avoid instances where the input file might contain whitesspaces, we have to ignore / trim the whitespaces first.
```sh
username=$(echo "$username" | xargs)
groups=$(echo "$groups" | xargs)
```
Check if a user in the input file exists in the system, and if so, skip creation of the user.
```sh
if id "$username" &>/dev/null; then
echo "User $username already exists. Skipping..." | tee -a "$LOG_FILE"
continue
fi
```
Create a personal group for the user if it doesn't exist already.
```sh
if ! getent group "$username" &>/dev/null; then
if ! groupadd "$username" 2>/dev/null; then
echo "Failed to create group $username. Permission denied." | tee -a "$LOG_FILE"
continue
fi
echo "Group $username created." | tee -a "$LOG_FILE"
fi
```
Create the user with a home directory and assign the personal group.
```sh
if ! useradd -m -g "$username" -s /bin/bash "$username" 2>/dev/null; then
echo "Failed to create user $username. Permission denied." | tee -a "$LOG_FILE"
continue
fi
echo "User $username created with home directory." | tee -a "$LOG_FILE"
```
Add the user to additional groups as specified in the input file.
```sh
IFS=',' read -ra ADDR <<< "$groups"
for group in "${ADDR[@]}"; do
group=$(echo "$group" | xargs)
if ! getent group "$group" &>/dev/null; then
if ! groupadd "$group" 2>/dev/null; then
echo "Failed to create group $group. Permission denied." | tee -a "$LOG_FILE"
continue
fi
echo "Group $group created." | tee -a "$LOG_FILE"
fi
if ! usermod -aG "$group" "$username" 2>/dev/null; then
echo "Failed to add user $username to group $group. Permission denied." | tee -a "$LOG_FILE"
continue
fi
echo "User $username added to group $group." | tee -a "$LOG_FILE"
done
```
Set permissions and ownership for the user's home directory.
```sh
chmod 700 "/home/$username"
chown "$username:$username" "/home/$username"
```
Using the function `generate_password` that we created earlier, generate a random password, set it for the user and log it in the `PASSWORD_FILE`.
```sh
password=$(generate_password)
echo "$username:$password" | chpasswd 2>/dev/null || { echo "Failed to set password for user $username. Permission denied."; continue; }
echo "$username,$password" >> "$PASSWORD_FILE"
echo "Password for user $username set." | tee -a "$LOG_FILE"
```
We can include a completion message for the "LOG_FILE".
```sh
echo "User creation process completed." | tee -a "$LOG_FILE"
```
## Example Input File
Create a file named `user_list.txt` with the following content:
```
flash; sudo,dev,www-data
thunder; sudo
thanos; dev,www-data
```
## Usage
To use the script, follow these steps.
1. Save the script as `create_users.sh`
2. Make the script executable - `chmod +x create_users.sh`
3. Run the script with `sudo` - `sudo ./create_users.sh user_list.txt`
**You can view the full script [here](https://github.com/emmanuelkaringi/HNG_Task_2/blob/main/create_users.sh).**
## Conclusion
This script simplifies the process of creating users and groups, setting up home directories, generating passwords, and logging actions. By automating these tasks, SysOps engineers can efficiently manage user accounts in a consistent and secure manner.

1,908,940 | My Experience with Python for Data Analysis | Hello, everyone! 🌟 Welcome back to the second installment of my journey into the world of Data... | 0 | 2024-07-02T12:31:44 | https://dev.to/mesfin_t/my-experience-with-python-for-data-analysis-14jo | datascience, machinelearning, python | **Hello, everyone! 🌟**
Welcome back to the second installment of my journey into the world of Data Science and Machine Learning. Today, I want to delve deeper into my experience with Python for data analysis. This post will focus on the technical aspects of how Python and its libraries have empowered my journey in understanding and applying Data Science concepts.
**Why Python for Data Analysis?**
Python emerged as my language of choice for several reasons. Its versatility, extensive libraries, and readability make it ideal for handling complex data tasks. Here’s a closer look at how Python has been instrumental in my learning journey:
**Key Python Libraries for Data Analysis**
**1. Pandas:**
**Functionality**: Pandas provides powerful data structures like DataFrames, essential for handling and manipulating structured data efficiently.
**Learning Experience**: Mastering Pandas has been crucial for data cleaning, transformation, and analysis. Techniques such as handling missing values `(df.dropna())`, grouping data `(df.groupby())`, and merging datasets `(df.merge())` have streamlined my workflow significantly.
**2. NumPy:**
**Functionality**: NumPy supports large multi-dimensional arrays and matrices, with a wide range of mathematical functions for operations.
**Learning Experience**: Understanding NumPy’s array operations `(np.array()`, `np.mean()`, etc. has enhanced my ability to perform numerical computations and data manipulations effectively.
**3. Matplotlib and Seaborn:**
**Functionality**: These libraries offer robust tools for creating visualizations, from basic plots to complex graphs.
**Learning Experience**: Visualizing data with Matplotlib `(plt.plot()`,` plt.hist())` and `Seaborn` `(sns.scatterplot()`, `sns.heatmap())` has been pivotal in gaining insights into data patterns and relationships.
**Real-World Application**
While I've used simplified sample data here for clarity, in real-world scenarios, datasets can be vast and sourced from diverse channels. However, the techniques and principles for data handling remain consistent, ensuring scalability and accuracy in analysis.
**Example Visualizations**
Let’s revisit some practical examples of visualizing data:
Histogram
```python
import matplotlib.pyplot as plt
import pandas as pd
data = pd.Series([1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5])
plt.figure(figsize=(10, 6))
plt.hist(data, bins=5, color='skyblue', edgecolor='black')
plt.title('Histogram of Sample Data')
plt.xlabel('Value')
plt.ylabel('Frequency')
plt.show()
```
The plot generated from above code
Scatter Plot
```python
import seaborn as sns
import pandas as pd
df = pd.DataFrame({
'x': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
'y': [2, 3, 4, 5, 4, 3, 6, 7, 8, 9]
})
plt.figure(figsize=(10, 6))
sns.scatterplot(x='x', y='y', data=df, color='red')
plt.title('Scatter Plot of x vs. y')
plt.xlabel('x')
plt.ylabel('y')
plt.show()
```
The plot generated from above code
Box Plot
```python
import seaborn as sns
import pandas as pd
data = pd.Series([1, 2, 3, 3, 4, 4, 4, 5, 5, 5, 5, 6, 6, 7])
plt.figure(figsize=(10, 6))
sns.boxplot(data=data, color='lightgreen')
plt.title('Box Plot of Sample Data')
plt.ylabel('Value')
plt.show()
```
The plot generated from above code
**Python for Data Analysis**
Python for data analysis has been a journey filled with exploration and growth. Here’s how I approached mastering the technical aspects:
**1. Data Cleaning:**
**Approach:** Using Pandas, I tackled data cleaning challenges such as handling missing values and formatting inconsistencies `(df.fillna()`, `df.drop_duplicates()`, `df.astype())`.
**Significance:** Clean data is fundamental for accurate analysis. Mastering data cleaning techniques enabled me to prepare datasets for meaningful insights.
**2. Exploratory Data Analysis (EDA):**
**Process:** Leveraging Pandas and visualization tools, I performed EDA to uncover patterns, outliers, and correlations (df.describe(), df.corr(), visual plots).
**Insight:** EDA provided a foundation for understanding data characteristics and informed subsequent analysis and modeling decisions.
**3. Statistical Analysis:**
**Application:** Using NumPy and SciPy, I conducted statistical analyses to derive insights and validate hypotheses (np.mean(), hypothesis testing).
**Impact:** Statistical techniques enhanced the depth of my analysis and supported data-driven decision-making processes.
**4. Data Visualization:**
**Utilization:** Creating compelling visualizations with Matplotlib and Seaborn facilitated effective communication of findings `(plt.plot()`, `sns.heatmap())`.
**Effectiveness:** Visualization played a crucial role in presenting insights clearly and persuasively to stakeholders.
**Practical Tips for Aspiring Data Analysts**
**Continuous Learning:** Start with foundational Python skills and progressively explore data analysis libraries.
**Hands-On Practice:** Apply learning to real-world datasets to reinforce concepts and gain practical experience.
**Community Engagement:** Engage with online communities and forums to seek guidance, share insights, and stay updated with industry trends.
**Conclusion**
My journey with Python for data analysis has been transformative, equipping me with essential skills to navigate complex data landscapes effectively. Aspiring data analysts, embrace Python’s capabilities, hone your technical skills, and dive into the vast world of data insights.
Stay tuned for next week’s post, where I’ll explore the nuances of data collection and cleaning—the cornerstone of robust data analysis. Let's continue this exciting journey together! 🌟 | mesfin_t |

**[CherrySaaS](https://github.com/itsmeadarsh2008/cherrysaas)** is a 100% **open-source Pythonic SaaS template** that lets you build crazy beautiful SaaS using **Chakra and Radix UIs** powered by Reflex. **It is currently a work in progress 🚧 and requires community contribution because I don't have the energy to write the entire template.** If I were to do an entire template, I would never open-source it as it would become hard to maintain alone. So, I need collaborators and community effort to remain it to be open-sourced. [Here's the planning in the notion. Comments are allowed on the notion site](https://adarshanalyzes.notion.site/CherrySaaS-35cb1391b024468896473aa50fa189db?pvs=4).
**It is meant for production but requires community contributions to complete.** It is currently in work progress but if people make useful contributions, it can be accomplished faster.
The reason is that it is a rare project as no free SaaS template has ever been made in Pure-Python. **There are proprietary 2 SaaS templates made using Reflex.** (**One more drawback, They're expensive**) So I decided to make a free one for the community too. I have looked at a SaaS template called [shipfast.com](shipfast.com) (which is getting popular nowadays). Ah, yes this also became an inspiration but I wanted to make one free.

Giving away shovels for free during the Gold Rush ✔_
**If you want to be a collaborator, reach out to me on Discord (adarshgourabmahalik) or post your GitHub email in this [discussion](https://github.com/itsmeadarsh2008/cherrysaas/discussions/1). Here's a discord link to preview the landing page of the template. **
[Let's get a preview about what I'm building 🚀](https://discord.com/channels/1029853095527727165/1063735841333198938/1252953503106732053)
In general, is there anything? that I'm missing from my notion plan about the template?
[**I copied this one from my own reddit post 😅, because I'm lacking contributors**]
Just comment "count me in" for further development for the project.

1,908,938 | Understanding final and const in Dart: A Beginner's Guide | Are you new to Dart and struggling to grasp the concepts of final and const? Don't worry! This blog... | 0 | 2024-07-02T12:31:08 | https://dev.to/osama_66b9d07fabcf9b74b8d/understanding-final-and-const-in-dart-a-beginners-guide-4m1a |
Are you new to Dart and struggling to grasp the concepts of `final` and `const`? Don't worry! This blog post will break it down for you in simple terms, with plenty of examples and analogies to help you understand these important keywords.
## Table of Contents
1. [Understanding Mutability](#understanding-mutability)
2. [The `final` Keyword](#the-final-keyword)
3. [The `const` Keyword](#the-const-keyword)
4. [Differences and Similarities](#differences-and-similarities)
5. [When to Use Which Keyword](#when-to-use-which-keyword)
## Understanding Mutability
Before we dive into `final` and `const`, let's first understand the concept of mutability. In programming, data types can be either mutable or immutable:
- **Mutable**: Can be changed after creation
- **Immutable**: Cannot be changed after creation
Let's look at some examples to understand this better.
### Immutable Types: The Box Analogy
Imagine you have a box with a number inside. This box represents an integer variable in Dart.
```dart
int a = 5;
```
In memory, this creates a "box" containing the value 5. Now, let's create another variable and assign it the value of `a`:
```dart
int b = a;
```
Both `a` and `b` are now pointing to the same box with the value 5. But what happens if we change `b`?
```dart
b = 10;
```
Instead of changing the value in the original box, Dart creates a new box with the value 10, and `b` now points to this new box. `a` still points to the original box with 5.
This is because integers in Dart are immutable. You can't change the value in the box; you can only create a new box with a new value.
### Mutable Types: The Bookshelf Analogy
Now, let's look at a mutable type, like a List. Think of a List as a bookshelf where you can add, remove, or rearrange books.
```dart
List<int> listA = [1, 2, 3];
List<int> listB = listA;
```
Here, both `listA` and `listB` are pointing to the same bookshelf. If we add a book to this shelf:
```dart
listB.add(4);
```
Both `listA` and `listB` will see this change, because they're looking at the same bookshelf. Lists in Dart are mutable, so we can change their contents without creating a new list.
## The `final` Keyword
The `final` keyword in Dart is used to create variables that can only be set once. Think of it as putting a lock on the variable name, not necessarily on the content.
### `final` with Immutable Types
When used with immutable types like integers or strings, `final` behaves similarly to a constant:
```dart
final int a = 5;
// a = 10; // This would cause an error
```
Here, `a` is locked to the value 5, and we can't reassign it.
### `final` with Mutable Types
With mutable types like Lists, `final` prevents reassignment of the variable, but the contents can still be modified:
```dart
final List<int> listA = [1, 2, 3];
// listA = [3, 4, 5]; // This would cause an error
listA.add(4); // This is allowed
print(listA); // Output: [1, 2, 3, 4]
```
Think of it as locking the bookshelf in place. You can't replace the entire bookshelf, but you can still add, remove, or rearrange the books on it.
## The `const` Keyword
The `const` keyword in Dart is used to create compile-time constants. It's like freezing the variable and its contents entirely.
```dart
const int a = 5;
// a = 10; // This would cause an error
const List<int> listA = [1, 2, 3];
// listA.add(4); // This would cause an error
```
With `const`, not only can you not reassign the variable, but you also can't modify its contents. It's like putting the entire bookshelf in a block of ice - you can't move the shelf, and you can't touch any of the books.
An interesting property of `const` is that identical const values share the same memory location:
```dart
const int a = 5;
const int b = 5;
print(identical(a, b)); // Output: true
```
This is like having multiple signs pointing to the same frozen bookshelf, saving memory.
## Differences and Similarities
| Feature | `final` | `const` |
|---------|---------|---------|
| Reassignment | Not allowed | Not allowed |
| Modification of mutable types | Allowed | Not allowed |
| Compile-time constant | No | Yes |
| Runtime value assignment | Allowed | Not allowed |
| Memory optimization for identical values | No | Yes |
## When to Use Which Keyword
- Use `final` when:
- You want to assign the value at runtime
- You need to modify the contents of mutable objects
- You're working with mutable objects that can't be made const (e.g., objects from external libraries)
- Use `const` when:
- The value is known at compile-time
- You want to ensure complete immutability
- You're defining constant values like PI or maximum values
- You're working with widget trees in Flutter for performance optimization
Remember, when in doubt, start with `final`. You can always change it to `const` later if all the conditions are met.
By understanding these concepts, you'll write more efficient and less error-prone Dart code. Happy coding!
## Additional Important Points
To deepen your understanding of `final` and `const`, let's explore some additional important points:
### Initialization Timing
1. **`final` Variables**:
- Can be initialized at runtime
- Perfect for values that are calculated or received during program execution
```dart
final currentTime = DateTime.now(); // Initialized at runtime
```
2. **`const` Variables**:
- Must be initialized with a constant value at compile-time
- Cannot depend on any calculation or value that's only known at runtime
```dart
const pi = 3.14159; // Known at compile-time
// const currentTime = DateTime.now(); // This would cause an error
```
### Usage in Classes
1. **`final` in Classes**:
- Can be used for instance variables (non-static class members)
- Useful for values that are set once per instance but may differ between instances
```dart
class Person {
final String name;
Person(this.name); // name is set once per instance
}
```
2. **`const` in Classes**:
- Typically used for static class members or top-level constants
- All instances of the class will share the same value
```dart
class MathConstants {
static const double pi = 3.14159;
static const double e = 2.71828;
}
```
### Performance Considerations
While both `final` and `const` can improve code safety, `const` can also provide performance benefits:
1. **Memory Optimization**:
As mentioned earlier, identical `const` values share the same memory location, which can save memory in large applications.
2. **Compile-time Checks**:
The Dart compiler can perform additional optimizations with `const` values since they're known at compile-time.
3. **Flutter Widgets**:
In Flutter, using `const` constructors for widgets can improve performance by reducing unnecessary rebuilds.
```dart
// This widget will never rebuild unless forced to
const MyWidget(text: 'Hello');
```
### Compile-time vs. Runtime Constants
Understanding the difference between compile-time and runtime constants is crucial:
1. **`final` (Runtime Constants)**:
- The value is fixed at runtime
- Can be used with values that are not known until the program runs
2. **`const` (Compile-time Constants)**:
- The value must be known before the program runs
- Offers stronger guarantees and potentially better performance
By understanding these additional points, you'll be better equipped to choose between `final` and `const` in various scenarios, leading to more efficient and robust Dart code.
Remember, mastering these concepts takes practice. Don't hesitate to experiment with different use cases to solidify your understanding. Happy coding!

4. Risk Management:
AI enhances risk management by evaluating credit scores, monitoring compliance, and conducting stress tests. Advanced algorithms assess a multitude of risk factors, providing a comprehensive risk profile. This capability allows financial institutions to mitigate risks proactively and maintain regulatory compliance.
The Synergy of API Integration and AI
The integration of APIs and AI in the finance industry creates a powerful synergy that drives innovation and efficiency. APIs enable seamless data exchange and connectivity, while AI processes this data to generate actionable insights. Together, they facilitate real-time decision-making, enhance customer experiences, and ensure robust security.
1. Real-Time Financial Insights:
By combining API connectivity with AI's analytical capabilities, financial institutions can offer real-time financial insights to their customers. For example, APIs can pull data from various financial accounts, while AI analyzes spending patterns and provides budgeting advice. This empowers customers to make informed financial decisions on the go.
2. Streamlined Operations:
The synergy of API and AI streamlines operations by automating routine tasks and optimizing workflows. APIs enable data integration across systems, while AI handles data analysis and decision-making. This reduces manual efforts, minimizes errors, and enhances operational efficiency.

APIs provide access to diverse data sources, while AI personalizes financial services based on this data. For instance, AI can analyze transaction histories, social media activity, and market trends to offer personalized investment recommendations. This level of customization enhances customer satisfaction and loyalty.
Conclusion
API integration and artificial intelligence are at the forefront of the finance industry's digital transformation. APIs facilitate seamless connectivity and collaboration, while AI drives innovation and efficiency through advanced data analysis and automation. Together, they empower financial institutions to deliver superior services, enhance security, and stay competitive in a rapidly changing landscape. As technology continues to evolve, the role of API integration and AI in finance will only grow, shaping the future of financial services.

He told me one of his clients has a need to do specific things to a database with a front end with a bunch of check boxes that will do all the DB things.
I told him it was a one week project at most and he disagreed thinking it was at least a 6 month project. To prove him wrong and that I have a bigger *deleted* I am to the point were I have a docker container with a mssql image running (a little harder than I though).
I am ready to load his 'sanitized' DB which is about useless. I'm looking for any gotchas since they are running this all under the OS that shall not be named.
He told me a URL would be fine so I am sure this can all be done with my humble ubuntu 22.04 machine.
I'm thinking of a script that will load a few thousand records and a good FE to give them a user interface.
From here I still feel that I am only a week away, but I said that a month ago. I'd love to finish it by Monday.
Any pointers or better yet, pitfalls to be aware of would be greatly appreciated and may even result in a payment of some sort (intentionally vague). Thanks in advance.

Smart contracts are a revolutionary technology that is changing our understanding of finance and asset management. In this emerging field, BitPower, as a pioneer, has demonstrated the great potential of smart contracts.
BitPower's smart contract technology makes the entire financial ecosystem more transparent, efficient and secure. The cumbersome procedures and human intervention in the traditional financial system are simplified and automated here. With its precise algorithms and tamper-proof characteristics, smart contracts ensure that every transaction is carried out within the rules and cannot be changed or deleted.
In the world of BitPower, smart contracts are at the core of all operations. They not only manage the flow of funds, but also automatically execute predetermined rules and conditions. This means that whether it is lending, investment or dividends, everything is determined by smart contracts, eliminating the risk of human operation. Users only need to deposit assets into BitPower's smart contracts, and the system will automatically complete the corresponding operations according to market conditions and preset rules.
For example, in BitPower's lending system, smart contracts are responsible for matching borrowers and lenders. When users deposit assets as collateral, smart contracts will instantly evaluate their value and calculate the corresponding loan amount and interest rate based on market conditions. This process is fully automated and transparent, and users can check their lending and returns at any time.
Smart contracts also bring inclusiveness to global financial services. No matter where you are, as long as you have an Internet connection, you can participate in the BitPower ecosystem. This decentralized design eliminates the geographical and identity restrictions in the traditional financial system, allowing more people to have the opportunity to enjoy financial services.
BitPower's smart contracts are not limited to financial transactions, but also extend to incentive mechanisms and community building. Users can get corresponding rewards by participating in the promotion and development of the platform. These reward mechanisms are also automatically executed by smart contracts to ensure fairness and transparency.
In general, the application of smart contracts in BitPower not only improves efficiency and security, but also breaks down the barriers of traditional finance and creates a more open and fair financial environment. Through smart contracts, BitPower not only simplifies complex financial operations, but also provides a trustworthy platform for global users, allowing everyone to participate and benefit fairly.
In this new world full of potential, BitPower is gradually realizing its vision through smart contract technology: building a decentralized, transparent and fair global financial ecosystem. This is not just a technological innovation, but also a new definition of the future of finance. #BTC #ETH #SC #DeFi | pingz_iman_38e5b3b23e011f | |

1,908,928 | Ssl Problem “Unable To Get Local Issuer Certificate” | In this age of modern era, where privacy is one of the biggest concern SSL/TLS certificates plays a... | 0 | 2024-07-02T12:24:38 | https://keploy.io/blog/community/ssl-problem-unable-to-get-local-issuer-certificate | webdev, javascript, programming, python |
In this age of modern era, where privacy is one of the biggest concern SSL/TLS certificates plays a vital for secure communication over the internet. They encrypt data, ensuring it is transmitted securely between servers and clients. However, while working with SSL/TLS, you may encounter the "Unable to Get Local Issuer Certificate" error. So let's try to understand why this error comes and what is SSL/TLS.
**What is SSL/TLS Certificate Chain ?**
A Certificate Authority (CA) is a trusted entity that issues SSL/TLS certificates. These certificates form a chain of trust, starting from the Root CA to Intermediate CAs, and finally to the Leaf certificate (the one installed on your server). This chain ensures that the certificate presented by a server is trusted by clients.
**What causes "Unable to Get Local Issuer Certificate" ?**
Usually, unable to get local issuer certificate error is caused by the misconfiguration of the SSL certificate on your machine. Here are some common causes of the error:
Missing Intermediate Certificates: Intermediate certificates act as a bridge between the Root CA and the Leaf certificate. If these intermediates are missing, the client cannot verify the certificate chain, leading to the error.
Misconfigured Server: Servers must be configured to send the entire certificate chain, excluding the Root CA. Misconfigurations, such as not including the intermediate certificates, result in clients being unable to verify the certificate.
Outdated Certificate Store: Operating systems and browsers maintain a certificate store containing trusted Root CAs. If these stores are outdated, the client's system may not recognize newer CAs, causing the error.
**How to resolve this Error ?**
For a quick workaround, you can disable SSL globally or locally but this isn't recommended since it creates a security issue. To resolve the error from root, you can try these steps: -
Updating the Certificate Store: Ensure your operating system's certificate store is up-to-date. On Linux, you can use package managers like apt or yum to update CA certificates. On Windows, updating the operating system generally updates the certificate store.
Configuring the Server Correctly: Add intermediate certificates to your server configuration. For Apache, include the intermediates in the SSLCertificateChainFile directive. For Nginx, concatenate the intermediate certificates with your server certificate in the ssl_certificate file.
Handling Self-Signed Certificates: If using self-signed certificates, manually add them to the client's trusted certificate store. On Linux, copy the certificate to /usr/local/share/ca-certificates/ and run update-ca-certificates. On Windows, use the Certificate Manager (certmgr.msc).
**How to prevent ‘unable to get local issuer certificate’ errors**
The main purpose of a SSL certificate is to confirm authentication so that the information passed between client and server is secure. To prevent the error, ensure that you have a valid SSL keep your certificate stores updated to avoid trust issues and regularly audit your SSL/TLS configurations, tools like SSL Labs' SSL Test can help identify issues and provide recommendations.
**Conclusion**
The "Unable to Get Local Issuer Certificate" error often stems from missing intermediate certificates, server misconfigurations, or outdated certificate stores.
**FAQ's**
What does the "Unable to Get Local Issuer Certificate" error mean?
The "Unable to Get Local Issuer Certificate" error indicates that the client's system cannot verify the certificate chain provided by the server. This usually occurs because the necessary intermediate certificates are missing or not correctly configured on the server. Without these intermediates, the client cannot establish a trusted connection to the server, leading to the error.
**How can I diagnose the "Unable to Get Local Issuer Certificate" error?**
To diagnose the error, you can use several methods:
Command Line Tools: Use openssl s_client -connectyourdomain.com:443-showcerts to check the certificate chain and identify any missing intermediates.
Browser Developer Tools: In Chrome, navigate to the Security tab in Developer Tools to inspect the SSL/TLS certificate. In Firefox, click the Padlock icon in the address bar to view certificate details.
Server Logs: Review your server logs for SSL/TLS-related errors that may indicate misconfigurations or missing certificates.
**How do I update the certificate store on my system?**
Updating the certificate store ensures your system recognizes the latest trusted Certificate Authorities (CAs). Here’s how you can do it on different operating systems:
**Linux**: Use your package manager to update CA certificates. For example, on Debian-based systems, run sudo apt-get update followed by sudo apt-get install ca-certificates. On Red Hat-based systems, use sudo yum update ca-certificates.
**Windows**: Updating Windows generally updates the certificate store. You can also manually update it via the Certificate Manager (certmgr.msc).
**macOS**: Keep your macOS system updated to ensure the certificate store is up-to-date.
**What steps should I take to correctly configure intermediate certificates on my server?**
To correctly configure intermediate certificates, follow these steps for your web server:
Apache: Ensure your intermediate certificates are included in the SSLCertificateChainFile directive. Example configuration:
```
SSLCertificateFile /path/to/your_domain.crt
SSLCertificateKeyFile /path/to/your_domain.key
SSLCertificateChainFile /path/to/intermediate_certificate.crt
```
Nginx: Concatenate your server certificate and intermediate certificates into a single file and specify it in the ssl_certificate directive. Example configuration:
```
ssl_certificate /path/to/your_domain_combined.crt;
ssl_certificate_key /path/to/your_domain.key;
```
Ensure the combined file includes both the server certificate and the intermediate certificates in the correct order. | keploy |

1,908,925 | From not knowing how to code to having my own shopify app, all in 9 months | As an app developer (18y) and Shopify store owner, I've always been intrigued by the intersection of... | 0 | 2024-07-02T12:21:55 | https://dev.to/axeltta/building-plussales-a-solo-developers-journey-to-enhance-shopify-store-performance-50fo |
As an app developer (18y) and Shopify store owner, I've always been intrigued by the intersection of technology and e-commerce. This fascination led me to build PlusSales, a Shopify app designed to help store owners optimize their conversion rates and drive sales. In this post, I want to share my journey of developing PlusSales, the challenges I faced, and the tools and technologies that made it possible.
The Idea Behind PlusSales
The inspiration for PlusSales (which you can check out here: [plussales.co](https://www.plussales.co/) came from my own experience running a Shopify store. I realized that many store owners, including myself, struggled to understand why customers were dropping off at various points in the sales funnel. I wanted to create a tool that would provide clear, actionable insights to help store owners improve their conversion rates and overall performance.
As I started creating the app, I was also learning to code for the first time on codeacademy in javascript then react.
1 - Remix
Remix provided a modern framework for building scalable and performant web applications. Its seamless integration with React made it an ideal choice for developing a dynamic and interactive user interface.
2 - React
React's component-based architecture allowed me to build reusable UI components and manage the application state efficiently. Its popularity and extensive community support were additional benefits.
3 - JavaScript
JavaScript was a natural choice for the project due to its versatility and widespread use in web development. It enabled me to write both front-end and back-end code, ensuring a smooth development process.
4 - Shopify Ecosystem
Leveraging Shopify's APIs and development tools was essential for integrating PlusSales with Shopify stores. The Shopify App Bridge and Polaris component library helped create a consistent and intuitive user experience.
Development Process
The development process was both challenging and rewarding. Here are some key steps I took:
1 - Planning and Design
I started with a clear vision of what I wanted PlusSales to achieve. I sketched out the main features and user flows, focusing on simplicity and usability. I made sure to do the bare minimum to get my app approved and on the shopify app store as I would then be able to better decide in what direction I wanted to app to go. I also planned that until I got a few thousand users, the app would remain 100% free.
2 - Building the Front-End
Using React and Remix, I developed the front-end components of PlusSales. The drag-and-drop functionality for building conversion funnels and the integration with Google Analytics were particularly challenging especially making Google's API work in the shopify ecosystem.
3 - Back-End Integration
The back-end was built using Node.js and Express, handling data storage, user authentication, and API integrations. I ensured that the app could securely fetch and store data from Shopify and Google Analytics.
4 - Deployment and Maintenance
Deploying PlusSales to the Shopify App Store was a significant milestone. The biggest challenge was getting the app approved by SHopify which turned out to be 100x easier than I thought, turns out they just try and scare people from making a non complete app, which is fair enough.
The Future of PlusSales
The journey of developing PlusSales has been incredibly fulfilling. As the app continues to evolve, I plan to add more features and integrations based on user feedback. The goal remains the same: to provide Shopify store owners with powerful tools to optimize their performance and drive sales all for free.
If you're a Shopify store owner looking to enhance your store's conversion rates, I invite you to try PlusSales. It's available on the Shopify App Store, and you can learn more about it at [plussales.co](I definitely learned a lot from PlusSales and still have a lot to learn.
) . Your feedback and suggestions are incredibly valuable as I continue to improve the app.
I definitely learned a lot from PlusSales and still have a lot to learn.
Thank you for reading about my journey.

In such cases [Supabase](https://supabase.com/) is a great open-source alternative to setting up a custom backend, and integrating it into an Angular app is fairly simple, given the existing supabase dependencies like [@supabase/supabase-js](https://github.com/supabase/supabase-js). The only prerequisite to make it work is **initialising a supabase project** and **generating an API key**.
However, I found out that managing environment variables in an Angular project is not really straight forward. Once we generate a project via the Angular CLI, we get the `environment.ts` and `environment.prod.ts` files, but these cannot be used for declaring such API keys, especially if we want to push our codebase to a github repository.
After some research I did, I discovered [@ngx-env/builder](https://www.npmjs.com/package/@ngx-env/builder) which, as it seems, provides us with a clean and secure way to store our environment variables.
You can find a sample project showcasing how it works here:
{% github dimeloper/angular-environment-variables %}
## Getting started
Once we are at our Angular project root directory we can simply run `ng add @ngx-env/builder` to get started. This command will install the necessary dependency, adjust the application builders accordingly and generate the environment types within `env.d.ts`.
Once this is complete we can extend the generated `env.d.ts` and its Env interface with our expected environment variables. For example:
```ts
declare interface Env {
readonly NODE_ENV: string;
// Replace the following with your own environment variables.
readonly NG_APP_ENV: string;
readonly NG_APP_PUBLIC_SUPABASE_URL: string;
readonly NG_APP_PUBLIC_SUPABASE_ANON_KEY: string;
}
```
Please keep in mind that the `NG_APP_` prefix **is mandatory**. In case you need to change it please consult the related [documentation](https://github.com/chihab/dotenv-run/tree/main/packages/angular#ng_app_-or-custom-prefix).
## Defining Environment Variables
Now we can use `.env` files on our local and production environments with the corresponding values. First we need to make sure that our `.gitignore` includes the `.env` file. Then we can create our local `.env` file as such:
```env
NG_APP_PUBLIC_SUPABASE_URL=https://test.supabase.co
NG_APP_PUBLIC_SUPABASE_ANON_KEY=keykeykeyvaluevalue
```
Since we included this file as part of our `.gitignore`, these values won't be pushed to our github repository.
## Usage in components / templates
We can import the actual values of our environment variables in our components as such:
```ts
supabaseUrl = import.meta.env.NG_APP_PUBLIC_SUPABASE_URL;
```
Basically the `import.meta.env` object will include all the environment variables we've defined.
## Differentiate environments across serve and build tasks
We could possibly use the default `NODE_ENV` values to differentiate between e.g. `development` and `production` environments, however I prefer having my own app environment values which for this sample project, I've defined within `package.json`.
Example:
```json
"scripts": {
"start:dev": "NG_APP_ENV=dev ng serve",
"start:staging": "NG_APP_ENV=staging ng serve",
"start:production": "NG_APP_ENV=production ng serve",
"build": "NG_APP_ENV=production ng build"
}
```
By doing this we have a **clear app environment separation**, while we are also able to differentiate pieces of implementation depending on the app environment, e.g. if we want to show a teaser component only on production or staging.
## Deployment / usage in production
Once our local setup is complete, we can overwrite the values of our environment variables, just by defining them on the staging/production system environment (e.g. `export NG_APP_PUBLIC_SUPABASE_URL="environment.specific.url"`), or by creating an `.env` file in there, including all the enviroment specific values (e.g. staging values on the testsystem, production values on the live server).
## Conclusion
Managing API keys and secret values that should be handled as environment variables is an essential part of any frontend application that should be production ready. The [@ngx-env/builder](https://www.npmjs.com/package/@ngx-env/builder) package provides us with an elegant and straightforward way to do so, when it comes to Angular apps. Enjoy!

1,908,874 | Paper detailing BitPower Loop’s security | Security Research of BitPower Loop BitPower Loop is a decentralized lending platform based on... | 0 | 2024-07-02T12:15:36 | https://dev.to/sang_ce3ded81da27406cb32c/paper-detailing-bitpower-loops-security-1ej6 | Security Research of BitPower Loop
BitPower Loop is a decentralized lending platform based on blockchain technology, dedicated to providing users with safe, transparent and efficient financial services. Its core security comes from multi-level technical measures and mechanism design, which ensures the robust operation of the system and the security of user funds. This article will introduce the security of BitPower Loop in detail from five aspects: smart contract security, decentralized management, data and transaction security, fund security and risk control mechanism.
1. Smart Contract Security
Smart contracts are the core components of BitPower Loop, and their codes must undergo strict security audits before deployment. These audits are usually conducted by third-party independent security companies to ensure that there are no vulnerabilities or malicious code in the contract. In addition, the immutability of smart contracts means that once deployed, no one (including the development team) can modify its rules and logic, which fundamentally eliminates the possibility of malicious operations. All operations are automatically executed by smart contracts, avoiding the risk of human intervention and ensuring the fairness and consistency of system operation.
2. Decentralized Management
BitPower Loop eliminates the risks brought by single point failures and central control through decentralized management. The system has no central management agency or owner, and all transactions and operations are jointly verified and recorded by blockchain nodes distributed around the world. This decentralized structure not only improves the system's anti-attack capabilities, but also enhances transparency. Users can publicly view all transaction records, which increases trust in the system.
3. Data and transaction security
BitPower Loop uses advanced encryption technology to protect users' data and transaction information. All data is encrypted during transmission and storage to prevent unauthorized access and data leakage. The consensus mechanism of the blockchain ensures the validity and immutability of each transaction, eliminating the possibility of double payment and forged transactions. In addition, the automated execution of smart contracts also avoids delays and errors caused by human operations, ensuring the real-time and accuracy of transactions.
4. Fund security
The secure storage of user funds is an important feature of BitPower Loop. Funds are stored on the blockchain through smart contracts and maintained by nodes across the entire network. Distributed storage avoids the risk of fund theft caused by centralized storage. In addition, the user's investment returns and shared commissions are automatically allocated to the user's wallet address by the smart contract after the conditions are met, ensuring the timely and accurate arrival of funds.
5. Risk Control Mechanism
BitPower Loop effectively manages lending risks by setting collateral factors and liquidation mechanisms. The collateral factors are independently set according to market liquidity and asset value fluctuations to ensure system stability and lending security. When the value of the borrower's assets falls below a certain threshold, the liquidation mechanism is automatically triggered, ensuring the repayment of the borrower's debt and protecting the interests of the fund provider. In addition, the immutability and automatic execution characteristics of smart contracts further enhance the security and reliability of the system.
Conclusion
BitPower Loop achieves high security and stability through multi-level security measures and mechanism design. Its smart contracts are strictly audited and immutable, decentralized management eliminates single point failure risks, advanced encryption technology protects data and transaction security, distributed storage ensures fund security, and risk control mechanisms manage lending risks. These security features together build a reliable decentralized financial platform that provides users with secure, transparent and efficient financial services. | sang_ce3ded81da27406cb32c | |

Furthermore, it has excellent documentation, a large community, and regular updates, making it a reliable choice for modern web development.
## Benefits of using Tailwind CSS
- **Utility-first approach**: Tailwind provides utility classes for common CSS properties, allowing you to build custom designs quickly and efficiently.
- **Customizable**: Tailwind's configuration file lets you customize the utility classes to match your design system and branding.
- **Fast development**: By applying styles directly in your HTML, you can speed up the development process and reduce the amount of CSS code you need to write.
- **Consistent design**: Tailwind's utility classes help maintain a consistent design across your website by following a predefined set of styles.
- **Responsive design**: Tailwind includes responsive utility classes that make it easy to create responsive layouts for different screen sizes.
- **Large community**: Tailwind has a large community of developers who share tips, tricks, and resources to help you get started and solve common problems.
## The Box Model in CSS
Before diving into Tailwind's padding, margin, and border utilities, let's briefly review the box model in CSS. The box model is a fundamental concept in CSS that describes how the elements on a web page are structured and displayed. The box model consists of four main components:
- **Content**: The innermost part where text and images appear.
- **Padding**: The space between the content and the border.
- **Border**: The line surrounding the padding and content.
- **Margin**: The outermost space that separates the element from other elements.
Understanding these components is crucial for creating well-structured layouts and designs in CSS.
Here is a visual representation of the box model:
## What is Tailwind Padding?
Padding is the space between an element's content and its border. It helps to create breathing room inside an element, making the content more readable and visually appealing.
### Tailwind Padding Classes
Tailwind CSS provides a variety of padding utility classes to add padding to an element. These classes are prefixed with p- followed by the size you want to apply. Here are some examples:
```html
<div class="p-4">Padding 4</div>
<div class="pt-2">Padding Top 2</div>
<div class="pr-3">Padding Right 3</div>
<div class="pb-5">Padding Bottom 5</div>
<div class="pl-6">Padding Left 6</div>
<div class="px-8">Padding Horizontal 8</div>
<div class="py-10">Padding Vertical 10</div>
```
[Here](https://codepen.io/devdojo/pen/xxRKOmq) is a CodePen example demonstrating Tailwind padding classes. Feel free to experiment with different padding values to see how they affect the layout.
## What is Tailwind Margin?
Margin is the space outside an element's border that separates it from other elements. It helps to create visual separation between elements and control the layout of a web page.
### Tailwind Margin Classes
Tailwind CSS provides margin utility classes to add margin to an element. These classes are prefixed with m- followed by the size you want to apply. Here are some examples:
```html
<div class="m-4">Margin 4</div>
<div class="mt-2">Margin Top 2</div>
<div class="mr-3">Margin Right 3</div>
<div class="mb-5">Margin Bottom 5</div>
<div class="ml-6">Margin Left 6</div>
<div class="mx-8">Margin Horizontal 8</div>
<div class="my-10">Margin Vertical 10</div>
```
[Here](https://codepen.io/devdojo/pen/rNMazYP) is a CodePen example demonstrating Tailwind margin classes. Play around with different margin values to see how they affect the spacing between elements.
## What is Tailwind Border?
A border is a line that surrounds an element's padding and content. It helps to visually separate elements and define their boundaries.
### Tailwind Border Classes
Tailwind CSS provides border utility classes to add borders to an element. These classes are prefixed with border- followed by the size, style, and color you want to apply. Here are some examples:
```html
<div class="border">Default Border</div>
<div class="border-2">Border 2</div>
<div class="border-4">Border 4</div>
<div class="border-t-2">Border Top 2</div>
<div class="border-r-4">Border Right 4</div>
<div class="border-b-2">Border Bottom 2</div>
<div class="border-l-4">Border Left 4</div>
<div class="border-dashed">Dashed Border</div>
<div class="border-dotted">Dotted Border</div>
<div class="border-double">Double Border</div>
<div class="border-solid">Solid Border</div>
```
Check out [this CodePen example](https://codepen.io/planetoftheweb/pen/jOMEozo) to see how different border styles look in practice.
## Putting It All Together
Now that you understand Tailwind padding, margin, and border utilities, you can combine them to create well-structured layouts and designs in your web development projects. By leveraging Tailwind's utility-first approach, you can build custom designs quickly and efficiently without writing CSS from scratch.
Here is an example of how you can use Tailwind padding, margin, and border classes together:
```html
<div class="m-4 p-4 border-2 border-gray-500">
<h1 class="text-2xl mb-4">Tailwind CSS Example</h1>
<p class="mb-2">This is a paragraph with some padding and margin.</p>
<button class="bg-blue-500 text-white p-2 rounded">Click Me</button>
</div>
```
In this example, we have a `div` element with margin, padding, and a border. Inside the `div`, we have a heading, a paragraph, and a button styled with Tailwind classes. This demonstrates how you can use Tailwind's utility classes to create a well-structured layout with minimal CSS code.
Here is how the example looks:

Smart contracts are a revolutionary technology that is changing our understanding of finance and asset management. In this emerging field, BitPower, as a pioneer, has demonstrated the great potential of smart contracts.
BitPower's smart contract technology makes the entire financial ecosystem more transparent, efficient and secure. The cumbersome procedures and human intervention in the traditional financial system are simplified and automated here. With its precise algorithms and tamper-proof characteristics, smart contracts ensure that every transaction is carried out within the rules and cannot be changed or deleted.
In the world of BitPower, smart contracts are at the core of all operations. They not only manage the flow of funds, but also automatically execute predetermined rules and conditions. This means that whether it is lending, investment or dividends, everything is determined by smart contracts, eliminating the risk of human operation. Users only need to deposit assets into BitPower's smart contracts, and the system will automatically complete the corresponding operations according to market conditions and preset rules.
For example, in BitPower's lending system, smart contracts are responsible for matching borrowers and lenders. When users deposit assets as collateral, smart contracts will instantly evaluate their value and calculate the corresponding loan amount and interest rate based on market conditions. This process is fully automated and transparent, and users can check their lending and returns at any time.
Smart contracts also bring inclusiveness to global financial services. No matter where you are, as long as you have an Internet connection, you can participate in the BitPower ecosystem. This decentralized design eliminates the geographical and identity restrictions in the traditional financial system, allowing more people to have the opportunity to enjoy financial services.
BitPower's smart contracts are not limited to financial transactions, but also extend to incentive mechanisms and community building. Users can get corresponding rewards by participating in the promotion and development of the platform. These reward mechanisms are also automatically executed by smart contracts to ensure fairness and transparency.
In general, the application of smart contracts in BitPower not only improves efficiency and security, but also breaks down the barriers of traditional finance and creates a more open and fair financial environment. Through smart contracts, BitPower not only simplifies complex financial operations, but also provides a trustworthy platform for global users, allowing everyone to participate and benefit fairly.

# Cannot Generate SAP Fiori Application in VS Code
SAP Fiori CAP applications do not have clear or documented application configuration file, which is used for `cds` or SAP's [Yeoman (dead?)](https://www.reddit.com/r/node/comments/16m7rrr/whats_up_with_yeoman/) Fiori app generator [@sap/generator-fiori](https://www.npmjs.com/package/@sap/generator-fiori).
Recently, I have spent significant time to figure out why I am unable to add another application using that generator. Apparently there is an if condition based on `package.json` `dependency` check. When I added [@sap/cds](https://www.npmjs.com/package/@sap/cds) to package.json, it started to detect it as valid Node.js project.
```json
...
"@sap/cds": ">=7"
...
```
From the other side, `cds` CLI does not check it at all, BUT... it checks if in project root folder is able to find `pom.xml` it detects it as a Java CAP project. Otherwise, it treats that as Node.js.
The critical issue with figuring it out is:
- application behavior it is not documented,
- both of these utility apps are NOT open-source
- [@sap/generator-fiori](https://www.npmjs.com/package/@sap/generator-fiori) it transpiled from TypeScript and not possible to review,
* (`cds` CLI fortunately is pure JS tho)
## Note
I get it. If I generated new project from the scratch using `cds` and copy-paste all CAP model/service configuration, I would avoid that situation. I did at the end, but we are not living in perfect greenfield world and even when CAP is pretty new, you still have to have someone to take care of brownfield. | mikolayek |

Hi all, welcome, and thanks for stopping by!
In this step-by-step guide, we will learn how to create a full-stack application with create, read, update, and delete (CRUD) functionality.
We will use Node.js and SQLite for the backend, and React for the frontend to create our user interface (UI).
Our project will be a mood tracker app where users can input their mood on a scale of 1-10. The app will display these moods in a list, with options to edit or delete them. Additionally, we will include a linear chart to track and visualize mood trends.
The final version will look like this:
Note: This tutorial assumes you have Node.js installed and an IDE installed preferably VScode. If not please go here to install Node.js and here for VScode.
Ok without further ado, let’s jump to it!
#####Backend Development
We will start with the backend. First, create a backend directory and open it in your favorite IDE. For this article, we will use VS Code.
After opening the backend directory in your code editor, open the terminal and run the following command:
```
npm init -y
```
This will register our project as a Node application and create a package.json file inside our directory.
Next, we need to add our project dependencies.
We will use Express to create our server, SQLite3 for our database, and Body-Parser to extract the body of requests.
In the terminal, run:
```
npm install express sqlite3 body-parser
```
After the installation is complete, we will set up our directory structure.
The folder structure inside the backend directory should look like this (create directories and files as needed):
```
/node_modules
/db
mood.db
/routes
index.js
mood.js
/models
mood.js
server.js
package.json
```
Open server.js, the main file of the Node.js application, and copy and paste the following code:
```
const express = require('express');
const sqlite3 = require('sqlite3').verbose();
const bodyParser = require('body-parser');
const app = express();
app.use(bodyParser.json());
let db = new sqlite3.Database('./db.sqlite');
app.get('/', (req, res) => {
res.send('Hello World!');
});
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
```
* We imported this code's express, sqlite3, and body-parser modules and initialized a new Express application.
* We used body-parser as middleware to parse incoming request bodies. We also initialized a new SQLite database (or opened it if it already exists).
* Defined a route handler for GET requests to the root URL (/), and started the server on port 3000.
To run the app with hot reload (so you don't have to restart the server each time you make a change). We can use a dependency called nodemon.
Install it by running:
```
npm install --save-dev nodemon
```
To use nodemon, update the scripts section inside package.json. Change the start script to look like this:
```
"start": "nodemon server.js"
```
Open your terminal and run:
```
npm start
```
Then, open your default browser and navigate to http://localhost:3000/. You should see "Hello World".
Your terminal should display the following message:
```
[nodemon] starting `node server.js`
Server started on port 3000
Connected to the mood database.
```
Congrats, you have created and run an Express server!
If you don’t see it running, check your terminal for any errors.
Now let's start working on the model and routes for our application.
A model defines the structure of an object, and routes perform the CRUD operations.
Open models/mood.js and add the following code:
```
const sqlite3 = require('sqlite3').verbose();
let db = new sqlite3.Database('./db/moods.db', (err) => {
if (err) {
console.error(err.message);
}
console.log('Connected to the moods database.');
});
db.run(`CREATE TABLE IF NOT EXISTS moods(
id INTEGER PRIMARY KEY AUTOINCREMENT,
mood INTEGER NOT NULL
)`, (err) => {
if (err) {
console.error(err.message);
}
console.log("Moods table created");
});
module.exports = db;
```
In this code, we imported SQLite and defined our database.
Created our table with id and mood columns, and exported our database.
Next, let's create our routes. Copy and paste the following code:
```
const express = require("express");
const router = express.Router();
const db = require("../models/mood");
router.post("/", (req, res) => {
const { mood } = req.body;
const query = `INSERT INTO moods(mood) VALUES(?)`;
db.run(query, [mood], function (err) {
if (err) {
console.error(err.message);
return res.status(500).json({ message: err.message });
}
res.send({ id: this.lastID, mood: mood });
});
});
router.get("/", (req, res) => {
const query = `SELECT * FROM moods`;
db.all(query, [], (err, rows) => {
if (err) {
console.error(err.message);
return res.status(500).json({ message: err.message });
}
res.send(rows);
});
});
router.put("/:id", (req, res) => {
const { mood } = req.body;
const { id } = req.params;
const query = `UPDATE moods SET mood = ? WHERE id = ?`;
db.run(query, [mood, id], function (err) {
if (err) {
console.error(err.message);
return res.status(500).json({ message: err.message });
}
res.send({ id: id, mood: mood });
});
});
router.delete("/:id", (req, res) => {
const { id } = req.params;
const query = `DELETE FROM moods WHERE id = ?`;
db.run(query, [id], function (err) {
if (err) {
console.error(err.message);
return res.status(500).json({ message: err.message });
}
res.send({ changes: this.changes });
});
});
module.exports = router;
```
Here, we imported Express to create a server application.
Using Express, we made a router object to define routes for the mood application.
We also imported our recently created database model.
For our CRUD operations, we created a new route for each action:
* Create: This route responds to all POST requests at the root path (/). We extract the mood from the request and then define a SQL query to insert a new mood. Run the query on our db module, passing the mood value as a parameter. We handle errors and send the response back to the client or a status code of 500 with the error message.
* Read: This route responds only to GET requests at the root path (/). We define a SQL query to select all moods, run the query, and send back the response with moods if successful. Otherwise, we send a status 500 code with the error message.
* Update: This route responds to PUT requests at the path /:id, mood id should be in the path like /6. Like POST, we extract the body from the request and get the id from the path. We create a query to update a specific mood based on the id. Then run the query, passing mood and id as parameters, and include error handling logic.
* Delete: This route responds only to DELETE requests at the path /:id. We get the id from the request, then create a query to delete it from the moods table if it exists, and apply the same error handling logic.
We exported our router object to use the routes in our server.js file.
Let's update our server.js file to include our router.
Also, remove the database file reference we moved inside our model. Updated server.js:
```
const express = require("express");
const bodyParser = require("body-parser");
const moodsRouter = require("./routes/mood");
const cors = require("cors");
const app = express();
app.use(cors());
app.use(bodyParser.json());
app.use("/moods", moodsRouter);
app.get("/", (req, res) => {
res.send("Hello World!");
});
app.listen(3001, () => {
console.log("Server started on port 3001");
});
```
Notice we also added the CORS middleware for local development and switched the port to 3001.
This will be helpful when integrating and testing our UI. In your terminal, run the following command to install CORS:
```
npm install --save-dev cors
```
Find out more about CORS [here](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS).
Now start your server app, and let’s test the routes. We can use curl inside the terminal to test.
Here's how you can do it for each type of request:
1. GET request: To fetch all moods, use the following command:
```
curl http://localhost:3001/moods
```
2. POST request: To create a new mood, use the -d flag to send data:
```
$body = @{
mood = 7
} | ConvertTo-Json
$response = Invoke-WebRequest -Uri http://localhost:3001/moods -Method POST -Body $body -ContentType "application/json"
```
3. PUT request: To update a mood, you need to know the id of the mood you want to update. Replace :id with the actual id of the mood:
```
# Replace :id with the actual id of the mood you want to update
$id = ":id"
$body = @{
mood = 8
} | ConvertTo-Json
$response = Invoke-WebRequest -Uri http://localhost:3001/moods/$id -Method PUT -Body $body -ContentType "application/json"
```
4. DELETE request: To delete a mood, you also need to know the id of the mood. Replace :id with the actual id of the mood:
```
# Replace :id with the actual id of the mood you want to delete
$id = ":id"
$response = Invoke-WebRequest -Uri http://localhost:3001/moods/$id -Method DELETE
```
Check your console for any errors.
You made it all the way here, congratulations! You built an application with CRUD functionality!
Now we are ready to move to the UI.
#####Frontend Development
For UI development, we first need to create a React app.
We'll use a tool called Create React App, which provides us with a template application to build on.
Open a new terminal, change the directory to frontEnd, and then type the following command:
```
npx create-react-app mood-tracker-ui
```
npx allows us to run npm packages without installing them.
It runs create-react-app, the third argument is the directory's name and application.
Now that we've created our app, change the directory to mood-tracker-ui:
```
cd mood-tracker-ui
```
Let's clean up by removing files and code we won't use.
Remove the following files: App.test.js, logo.svg, reportWebVitals.js, and setupTests.js.
We'll clean up index.js to look like this:
```
import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
<React.StrictMode>
<App />
</React.StrictMode>
);
```
Next, App.js should look like this:
this:
```
function App() {
return (
<div className="App">
<h1>Hello World</h1>
</div>
);
}
export default App;
```
Now let's set up our folder structure and run our application. The folder structure should look like this (create directories and files as needed):
```
/frontend
/src
/components
/MoodInput
/MoodList
/MoodChart
/services
/apiService.js
/assets
/styles
/main.css
App.js
index.js
/public
index.html
package.json
```
Inside your terminal, run the following command:
```
npm run start
```
A new tab will open in your default browser and navigate to http://localhost:3000/. You should see something like this:
Great! Let's start with our API service to add our CRUD functionality. We need methods for GET, POST, PUT, and DELETE requests.
Open apiService.js and insert the following code:
```
const API_URL = "http://localhost:3001";
export const getMoodsAPI = async () => {
const response = await fetch(`${API_URL}/moods`);
const data = await response.json();
return data;
};
export const addMoodAPI = async (mood) => {
const response = await fetch(`${API_URL}/moods`, {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({ mood }),
});
const data = await response.json();
return data;
};
// Update mood
export const updateMoodAPI = async (id, updatedMood) => {
const response = await fetch(`${API_URL}/moods/${id}`, {
method: "PUT",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(updatedMood),
});
if (!response.ok) {
throw new Error("Failed to update mood");
}
return response.json();
};
// Delete mood
export const deleteMoodAPI = async (id) => {
const response = await fetch(`${API_URL}/moods/${id}`, {
method: "DELETE",
});
if (!response.ok) {
throw new Error("Failed to delete mood");
}
return response.json();
};
```
Here's what each function does:
* getMoodsAPI: Fetches all moods from the API.
* addMoodAPI: Sends a POST request to add a new mood.
* updateMoodAPI: Sends a PUT request to update a specific mood by ID.
* deleteMoodAPI: Sends a DELETE request to remove a mood by ID.
Now that our API service is ready, let's build our components.
Start with MoodInput.js. Open the file and paste this code:
```
import { useState } from "react";
const MoodInput = ({ addMood }) => {
const [mood, setMood] = useState("");
const [error, setError] = useState(null);
const handleSubmit = (e) => {
e.preventDefault();
if (mood === "" || mood > 10) {
setError("Please enter a value between 1 and 10");
} else {
setError(null);
addMood(mood);
setMood("");
}
};
return (
<form onSubmit={handleSubmit} className="mood-form">
<label htmlFor="mood-input">
On a scale of 1-10, how are you feeling today?
</label>
<input
id="mood-input"
type="number"
min="1"
max="10"
value={mood}
onChange={(e) => setMood(e.target.value)}
/>
<button type="submit">Submit</button>
{error && <p>{error}</p>}
</form>
);
};
export default MoodInput;
```
In this component:
* We use the useState hook to manage the mood and error states.
The handleSubmit function handles form submission. Validates the mood input, and adds the mood if valid.
* The form includes an input for the mood and a submit button.
If the input has an error we render an error message.
Finally, we export the MoodInput component.
Next, let's create the MoodList component. This component will display all moods. Paste the following code inside the MoodList.js file:
```
import { useState } from "react";
import {
updateMoodAPI,
deleteMoodAPI,
} from "../../services/apiService/moodService";
const MoodList = ({ moods, deleteMood, updateMood }) => {
const [editingMoodId, setEditingMoodId] = useState(null);
const [editingMoodValue, setEditingMoodValue] = useState("");
const handleUpdateMood = async (id) => {
try {
const updated = await updateMoodAPI(id, { mood: editingMoodValue });
updateMood(id, updated);
setEditingMoodId(null);
setEditingMoodValue("");
} catch (error) {
console.error(error);
}
};
const handleDeleteMood = async (id) => {
try {
await deleteMoodAPI(id);
deleteMood(id);
} catch (error) {
console.error(error);
}
};
return (
<div className="mood-list">
<ul>
{moods?.map((mood, index) => (
<li key={index}>
{index}-
{editingMoodId === mood.id ? (
<>
<input
type="number"
min="1"
max="10"
value={editingMoodValue}
onChange={(e) => setEditingMoodValue(e.target.value)}
/>
<button onClick={() => handleUpdateMood(mood.id)}>Save</button>
</>
) : (
<>
{mood.mood}
<button
onClick={() => {
setEditingMoodId(mood.id);
setEditingMoodValue(mood.mood);
}}
>
Edit
</button>
</>
)}
<button onClick={() => handleDeleteMood(mood.id)}>Delete</button>
</li>
))}
</ul>
</div>
);
};
export default MoodList;
```
In this component:
* We import the necessary hooks and API services.
* We define the MoodList functional component, initializing the state for the ID and value of the mood being edited.
* The handleUpdateMood and handleDeleteMood methods use the API service methods for updating and deleting moods. We use try-catch blocks for error handling.
* When rendering, we map over the moods and create a list item for each one. If the current mood is being edited, an input and save button are displayed. Otherwise, we display the current mood with an edit button. The delete button is always available.
*Finally, we export the MoodList component.
We'll add a chart component for a visual representation of the moods.
This component uses the open-source libraries react-chartjs-2 and chart.js. Run the following command to install them:
```
npm install --save react-chartjs-2 chart.js
```
After installing the dependencies, paste the following code inside the MoodChart component:
```
import React from "react";
import {
Chart as ChartJS,
CategoryScale,
LinearScale,
PointElement,
LineElement,
Title,
Tooltip,
Legend,
} from "chart.js";
import { Line } from "react-chartjs-2";
ChartJS.register(
CategoryScale,
LinearScale,
PointElement,
LineElement,
Title,
Tooltip,
Legend
);
const MoodChart = ({ moods }) => {
const moodValues = moods?.map((mood) => Number(mood.mood));
const data = {
labels: moods?.map((mood, index) => `Day ${index + 1}`),
datasets: [
{
label: "Mood",
data: moodValues,
borderColor: "rgb(75, 192, 192)",
backgroundColor: "rgba(75, 192, 192, 0.5)",
},
],
};
const options = {
responsive: true,
plugins: {
legend: {
position: "top",
},
title: {
display: true,
text: "Mood Chart",
},
},
scales: {
x: {
type: "category",
},
y: {
type: "linear",
beginAtZero: true,
},
},
};
return <Line options={options} data={data} />;
};
export default MoodChart;
```
In this component:
* We import the necessary libraries and components.
* Then register the required Chart.js components.
* Inside our MoodChart component. we map through the moods array to extract mood values and labels.
* We define the data and options for the chart.
* The Line chart component is rendered with the required properties.
* Finally, we export the MoodChart component.
Now that we have our components, it's time to import them into App.js. Add the following code:
```
import { useState, useEffect } from "react";
import MoodChart from "./components/MoodChart/MoodChart";
import MoodInput from "./components/MoodInput/MoodInput";
import MoodList from "./components/MoodList/MoodList";
import { getMoodsAPI, addMoodAPI } from "./services/apiService/moodService";
import "./App.css";
function App() {
const [moods, setMoods] = useState([]);
const updateMood = (id, updatedMood) => {
setMoods((prevMoods) =>
prevMoods.map((mood) => (mood.id === id ? updatedMood : mood))
);
};
const deleteMood = (id) => {
setMoods((prevMoods) => prevMoods.filter((mood) => mood.id !== id));
};
useEffect(() => {
const fetchMoods = async () => {
const moods = await getMoodsAPI();
setMoods(moods);
};
fetchMoods();
}, []);
const addMood = async (mood) => {
const newMood = await addMoodAPI(mood);
setMoods([...moods, newMood]);
};
return (
<div className="app">
<div className="mood-header">
<h1>Mood Tracker</h1>
<MoodInput addMood={addMood} />
</div>
<div className="mood-container">
<MoodList
moods={moods}
deleteMood={deleteMood}
updateMood={updateMood}
/>
<MoodChart moods={moods} />
</div>
</div>
);
}
export default App;
```
In this file:
* We import the necessary libraries and newly created components.
* Inside our App component, we initialize the state for moods. Define methods for handling mood creation, updates, and deletions.
* The useEffect hook fetches all moods from our database when the component renders.
* We render our components and pass them the necessary props.
* Finally, we export the App component.
Run the app and you should see the full functionality now, make sure your server app is running too, and check your console for any errors.
Amazing! You’ve reached this point, we’ve successfully created a full-stack application. Now, we need to add some styling. In the next section, we’ll cover minor styling tweaks, but feel free to get creative and add your flair.
#####Styling
Open App.css and paste the following code:
```
body {
background: mintcream;
}
.mood-header {
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
margin-bottom: 20px;
}
.mood-container {
display: grid;
grid-template-columns: 1fr 1fr 1fr 0.5fr 0.5fr;
gap: 10px;
}
.mood-form > * {
margin-left: 10px;
}
.mood-list {
grid-column: 2;
}
.mood-list li {
margin-bottom: 10px;
}
.mood-list li button {
margin-left: 10px;
}
.mood-chart {
grid-column: 3 / span 2;
}
```
Here’s what we’re doing:
* Body: Setting the background color to mintcream.
* Header: Using Flexbox to center items vertically and horizontally, with some space below.
* Mood Container: Using a grid layout to position MoodList and MoodChart. MoodList takes one column, and MoodChart spans two columns, both centered.
* Mood List: Adding space between list items and buttons.
Import App.css in your App.js file, then reload your application to see the changes.
#####Conclusion
Throughout this journey, we built a full-stack application with a React UI, an Express.js server, and SQLite for data storage. We also added some styling using Flexbox and Grid layouts.
#####Next Steps
Here are some ideas for further improvements:
* **Testing**: Add tests using Jest and React Testing Library.
* **Functionality**: Enhance features, like adding real dates to moods.
* **Styling**: Add more styles, such as icons instead of buttons, custom fonts, and shadows.
* **Deployment**: Deploy the application.
Thanks for sticking with it! You’ve learned a thing or two. Please share your feedback and like the article.

We had everything ready – idea, wireframe, project requirements, and we were about to start the development. Until then, we had always used the same set of tools, considering client requirements and recent advancements in technologies.
But lately, we have heard about some new frontend tools that might make the development process even smoother and enhance our client business’s growth. This is when we got a query while choosing ReactJS for [frontend development](https://radixweb.com/front-end-development).
We know ReactJS has been a trusted JavaScript library for developers like us who want to build interactive and dynamic web applications. It’s like that trusty hammer that never lets you down. However, with the evolution of frontend development, new and exciting alternative tools can offer better efficiency and unique benefits.
So, we began brainstorming and jotting down some points for exploring other tools that could serve as potential ReactJS alternatives.
In this article, we will explore some of these alternatives to ReactJS. Think of it as discovering new tools in your toolbox that could make your project development even easier. We will consider various frontend technologies like Vue.js, which offers simplicity and flexibility, or Angular, which has powerful built-in features. There’s also Svelte, which promises faster performance by compiling your code into efficient JavaScript at build time. Along with that, there are also other React alternatives that will be considered.
By the end of this journey, you’ll better understand these ReactJS alternatives and how they might fit into your next web development project.
So, let’s see what new tools we can add to our frontend development toolkit!
## Why are You Looking for Alternatives to ReactJS?
While ReactJS is a popular library for front end development, there could be several reasons why developers may seek React JS alternatives.
- Missing Out on MVC Architecture
- Steep Learning Curve
- Not a Good Developer Experience
- Diverse Project Requirements
## Understanding the Popularity of React
There’s no denying the fact that the popularity of React is increasing day by day.
As per the Stack Overflow survey, React.js is the second most common web technology used by all professional developers, with 40.58%.
Also, [82% of JavaScript developers utilize React](https://radixweb.com/blog/frontend-statistics) as their primary frontend framework.
Let’s understand several reasons why React.js has gained so much popularity in frontend development community:
- Virtual DOM
- JavaScript Ecosystem Integration
- Reusability and Scalability
- Declarative Syntax
Top ReactJS Alternatives
In short, Reacct.js is popular, but what if we don’t want to use it anymore? Does it have any alternatives? Well, the answer to this question is YES.
**1) Preact:** Lightweight and compatible with React API.
**2) Svelte:** High performance with minimal runtime overhead.
**3) Inferno JS:** High-performance, mobile-friendly apps.

There... | 0 | 2024-07-02T12:06:45 | https://dev.to/deepnikode/enhancing-data-security-with-aes-encryption-in-java-95 | java, security, api, coding |
Encryption is a fundamental aspect of Information Security practice to protect sensitive data. There could be several use cases to encrypt data to hide sensitive information like password, card details, contact details, and several other details.🔑
The AES Algorithm requires a plain-text and a secret key for encryption and the same secret key is required again to decrypt it.
## 🔍 How It Works
**THEORY**
- Encryption: Converts plain text into a secure, encrypted format using the AES algorithm.
- Decryption: Reverts the encrypted data back to its original form, ensuring data integrity and confidentiality.

1,908,856 | Paper detailing BitPower Loop’s security | Security Research of BitPower Loop BitPower Loop is a decentralized lending platform based on... | 0 | 2024-07-02T12:02:26 | https://dev.to/kjask_jklshd_cecbd37d6d57/paper-detailing-bitpower-loops-security-2e49 | Security Research of BitPower Loop
BitPower Loop is a decentralized lending platform based on blockchain technology, dedicated to providing users with safe, transparent and efficient financial services. Its core security comes from multi-level technical measures and mechanism design, which ensures the robust operation of the system and the security of user funds. This article will introduce the security of BitPower Loop in detail from five aspects: smart contract security, decentralized management, data and transaction security, fund security and risk control mechanism.
1. Smart Contract Security
Smart contracts are the core components of BitPower Loop, and their codes must undergo strict security audits before deployment. These audits are usually conducted by third-party independent security companies to ensure that there are no vulnerabilities or malicious code in the contract. In addition, the immutability of smart contracts means that once deployed, no one (including the development team) can modify its rules and logic, which fundamentally eliminates the possibility of malicious operations. All operations are automatically executed by smart contracts, avoiding the risk of human intervention and ensuring the fairness and consistency of system operation.
2. Decentralized Management
BitPower Loop eliminates the risks brought by single point failures and central control through decentralized management. The system has no central management agency or owner, and all transactions and operations are jointly verified and recorded by blockchain nodes distributed around the world. This decentralized structure not only improves the system's anti-attack capabilities, but also enhances transparency. Users can publicly view all transaction records, which increases trust in the system.
3. Data and transaction security
BitPower Loop uses advanced encryption technology to protect users' data and transaction information. All data is encrypted during transmission and storage to prevent unauthorized access and data leakage. The consensus mechanism of the blockchain ensures the validity and immutability of each transaction, eliminating the possibility of double payment and forged transactions. In addition, the automated execution of smart contracts also avoids delays and errors caused by human operations, ensuring the real-time and accuracy of transactions.
4. Fund security
The secure storage of user funds is an important feature of BitPower Loop. Funds are stored on the blockchain through smart contracts and maintained by nodes across the entire network. Distributed storage avoids the risk of fund theft caused by centralized storage. In addition, the user's investment returns and shared commissions are automatically allocated to the user's wallet address by the smart contract after the conditions are met, ensuring the timely and accurate arrival of funds.
5. Risk Control Mechanism
BitPower Loop effectively manages lending risks by setting collateral factors and liquidation mechanisms. The collateral factors are independently set according to market liquidity and asset value fluctuations to ensure system stability and lending security. When the value of the borrower's assets falls below a certain threshold, the liquidation mechanism is automatically triggered, ensuring the repayment of the borrower's debt and protecting the interests of the fund provider. In addition, the immutability and automatic execution characteristics of smart contracts further enhance the security and reliability of the system.
Conclusion
BitPower Loop achieves high security and stability through multi-level security measures and mechanism design. Its smart contracts are strictly audited and immutable, decentralized management eliminates single point failure risks, advanced encryption technology protects data and transaction security, distributed storage ensures fund security, and risk control mechanisms manage lending risks. These security features together build a reliable decentralized financial platform that provides users with secure, transparent and efficient financial services.

1,908,860 | Service Container Bootstrap: Getting Started | Before starting the topic, create two new files in controllers directory: destroy.php that... | 0 | 2024-07-02T12:05:12 | https://dev.to/ghulam_mujtaba_247/service-container-bootstrap-getting-started-293j | webdev, beginners, programming, php | Before starting the topic, create two new files in controllers directory:
1. `destroy.php` that contains the code used to delete a note from the database.
2. `store.php` that contains the code to create a new note using forms and request methods.
## Intro to Service Container
A Service Container is a design pattern that centralizes the management of dependencies between objects, providing a structured way to access and manage services within an application.
It acts as a registry for services within a website.
## Container Class
Firstly create a file named `Controller.php` in Core directory. In this initialize the Container class, that is responsible for managing service bindings and resolutions.
- bind(): Registers a service with the container.
- resolve(): Retrieves a service from the container.
```php
class Container {
protected $bindings = [];
public function bind($key, $resolver) {
$this->bindings[$key] = $resolver;
}
public function resolve($key) {
if (!array_key_exists($key, $this->bindings)) {
throw new Exception("No matching binding found for {$key}");
}
$resolver = $this->bindings[$key];
return call_user_func($resolver);
}
}
```
## App Class
The App class acts as a interface for the Container, providing a convenient interface for accessing services.
- setContainer(): Sets the container instance for the App.
- container(): Retrieves the container instance.
- bind(): Registers a service with the container.
- resolve(): Retrieves a service from the container.
```php
class App {
protected static $container;
public static function setContainer($container) {
static::$container = $container;
}
public static function container() {
return static::$container;
}
public static function bind($key, $resolver) {
static::container()->bind($key, $resolver);
}
public static function resolve($key) {
return static::container()->resolve($key);
}
}
```
## Bootstrap
Bootstrap is a point of an application, where everything is set up and initialized.
```php
$container = new Container();
$container->bind('Core\Database', function () {
$config = require base_path('config.php');
return new Database($config['database']);
});
App::setContainer($container);
```
In this , the bootstrap process:
1. Creates a new Container instance ($container)
2. Registers services with the container using the `bind` method (e.g., Core\Database)
3. Sets the container for the App using `App::setContainer($container)`
## Controller
Services can be resolved from the container in controllers using the `App::resolve()` method.
```php
$db = App::resolve('Core\Database');
```
Now a service container is properly built and you can see the project is working well.
I hope that you have clearly understood it. | ghulam_mujtaba_247 |

1,908,855 | Essential Hooks for Every Developer | Introduction - What is a React Hook? A React Hook is a special function that lets you... | 0 | 2024-07-02T12:02:19 | https://dev.to/frtechy/essential-hooks-for-every-developer-16do | webdev, react, javascript | ### Introduction - What is a React Hook?
A React Hook is a special function that lets you "hook into" React features like state and lifecycle methods, enabling functional components to manage state and side effects.
Now, you've decided to build a React app, leveraging the power of React hooks. With numerous hooks available, it can be challenging to know which ones to use.
Let's explore the essential hooks, understand their functions, and see some concise examples to get you started:
### State Management Hooks
#### `useState`
The `useState` hook is fundamental for managing state and rendering components upon state changes.
```jsx
import React, { useState } from 'react';
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<p>{count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
```
#### `useReducer`
The `useReducer` hook is ideal for handling more complex state logic.
```jsx
import React, { useReducer } from 'react';
const initialState = { count: 0 };
function reducer(state, action) {
switch (action.type) {
case 'increment': return { count: state.count + 1 };
case 'decrement': return { count: state.count - 1 };
default: return state;
}
}
function Counter() {
const [state, dispatch] = useReducer(reducer, initialState);
return (
<div>
<p>{state.count}</p>
<button onClick={() => dispatch({ type: 'increment' })}>Increment</button>
<button onClick={() => dispatch({ type: 'decrement' })}>Decrement</button>
</div>
);
}
```
### Effect Hooks
#### `useEffect`
Effect hooks allow you to perform side effects, such as data fetching or DOM manipulation.
```jsx
import React, { useState, useEffect } from 'react';
function Example() {
const [count, setCount] = useState(0);
useEffect(() => {
document.title = `Count: ${count}`;
}, [count]);
return (
<div>
<p>{count}</p>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
```
#### `useLayoutEffect`
`useLayoutEffect` runs synchronously after all DOM mutations, useful for operations that need to occur before the browser repaints.
```jsx
import React, { useLayoutEffect, useRef } from 'react';
function LayoutEffectExample() {
const ref = useRef();
useLayoutEffect(() => {
console.log(ref.current.getBoundingClientRect());
}, []);
return <div ref={ref}>Measure my dimensions</div>;
}
```
### Ref Hooks
#### `useRef`
The `useRef` hook allows you to persist values across renders without causing a re-render.
```jsx
import React, { useRef } from 'react';
function TextInputWithFocusButton() {
const inputEl = useRef(null);
const onButtonClick = () => {
inputEl.current.focus();
};
return (
<div>
<input ref={inputEl} type="text" />
<button onClick={onButtonClick}>Focus the input</button>
</div>
);
}
```
#### `useImperativeHandle`
`useImperativeHandle` customizes the instance value that is exposed when using `ref` in parent components.
```jsx
import React, { useImperativeHandle, useRef, forwardRef } from 'react';
const FancyInput = forwardRef((props, ref) => {
const inputRef = useRef();
useImperativeHandle(ref, () => ({
focus: () => {
inputRef.current.focus();
}
}));
return <input ref={inputRef} />;
});
function Parent() {
const inputRef = useRef();
return (
<div>
<FancyInput ref={inputRef} />
<button onClick={() => inputRef.current.focus()}>Focus the input</button>
</div>
);
}
```
### Performance Hooks
#### `useMemo`
`useMemo` memoizes expensive calculations, recomputing the cached value only when its dependencies change.
```jsx
import React, { useMemo } from 'react';
function ExpensiveCalculationComponent({ num }) {
const result = useMemo(() => num * 2, [num]);
return <div>Result: {result}</div>;
}
```
#### `useCallback`
`useCallback` memoizes callback functions, preventing unnecessary re-creations on each render.
```jsx
import React, { useState, useCallback } from 'react';
function Button({ onClick }) {
return <button onClick={onClick}>Click me</button>;
}
function App() {
const [count, setCount] = useState(0);
const handleClick = useCallback(() => setCount(count + 1), [count]);
return (
<div>
<p>{count}</p>
<Button onClick={handleClick} />
</div>
);
}
```
### Context Hooks
#### `useContext`
`useContext` accesses values from a context provider.
```jsx
import React, { useContext } from 'react';
const MyContext = React.createContext();
function Display() {
const value = useContext(MyContext);
return <div>{value}</div>;
}
function App() {
return (
<MyContext.Provider value="Hello, World!">
<Display />
</MyContext.Provider>
);
}
```
### Transition Hooks
#### `useTransition`
`useTransition` marks state updates as non-urgent, improving user experience by deferring heavy computations.
```jsx
import React, { useState, useTransition } from 'react';
function FilterList({ items }) {
const [filter, setFilter] = useState('');
const [isPending, startTransition] = useTransition();
const filteredItems = items.filter((item) =>
item.toLowerCase().includes(filter.toLowerCase())
);
return (
<div>
<input
type="text"
value={filter}
onChange={(e) => {
startTransition(() => setFilter(e.target.value));
}}
/>
{isPending ? <p>Loading...</p> : filteredItems.map((item) => <p key={item}>{item}</p>)}
</div>
);
}
```
#### `useDeferredValue`
`useDeferredValue` defers a value update to maintain responsiveness.
```jsx
import React, { useState, useDeferredValue } from 'react';
function DeferredList({ items }) {
const [filter, setFilter] = useState('');
const deferredFilter = useDeferredValue(filter);
const filteredItems = items.filter((item) =>
item.toLowerCase().includes(deferredFilter.toLowerCase())
);
return (
<div>
<input type="text" value={filter} onChange={(e) => setFilter(e.target.value)} />
{filteredItems.map((item) => (
<p key={item}>{item}</p>
))}
</div>
);
}
```

Innovative Materials and Textures
Innovation in materials and textures is another exciting trend for Fall/Winter 2023-2024. While traditional smooth leather remains popular, there’s a growing interest in textured finishes such as suede, nubuck, and embossed leather. These textures add depth and interest to leather jackets, making them stand out in a crowd.
Additionally, mixed-media jackets that combine leather with other materials like wool, nylon, or even denim are gaining traction. These combinations not only enhance the visual appeal of the jackets but also improve functionality and comfort. For example, a mens long shearling jacket might feature leather sleeves and a woolen body, offering the best of both worlds in terms of warmth and style.
Versatility and Layering
One of the key attributes of leather jackets this season is their versatility. Designers are creating pieces that can be easily layered, allowing for adaptability in various weather conditions. Look for jackets with removable liners, adjustable hoods, and multiple pockets that enhance their functionality.
Layering is not just practical but also adds a stylish dimension to your outfit. Pair a leather jacket with a chunky knit sweater or a sleek turtleneck for a look that’s both warm and fashionable. The men’s shearling leather jacket, in particular, is perfect for layering, as its plush lining provides ample insulation without the need for bulky outerwear.
Statement Details
This season, it’s all about the details. From oversized buckles and metal hardware to intricate stitching and embossed patterns, the small touches are what set the Fall/Winter 2023-2024 leather jackets apart. These details add a sense of craftsmanship and luxury to the jackets, making them investment pieces that can elevate any wardrobe.
For those who prefer a more understated look, there are plenty of options with subtle yet impactful details. Think tonal stitching, minimalist zippers, and clean lines that offer a refined, sophisticated aesthetic. No matter your personal style, there’s a leather jacket this season that can enhance your look with just the right amount of detail.
Conclusion
As you update your wardrobe for the colder months, staying ahead of the curve with the latest leather jacket trends is a must. Whether you’re drawn to the classic appeal of a mens long shearling jacket, the rugged charm of a men’s shearling leather jacket, or the bold new colors and patterns, there’s something for everyone this Fall/Winter 2023-2024. Embrace the versatility, sustainability, and innovative designs that define this season’s offerings, and make a statement with a leather jacket that reflects your personal style.
With these trends in mind, you’re sure to find the perfect leather jacket that not only keeps you warm but also ensures you stay stylish throughout the season. | rose_emilia_7d1c74ae7db6e |

1,908,850 | Svelte vs. React | Introduction During recent years, there has been a continuous increase in the number of... | 0 | 2024-07-02T11:58:21 | https://dev.to/dannytech/svelte-vs-react-18al | webdev, programming, react, svelte | ## Introduction
During recent years, there has been a continuous increase in the number of new JavaScript libraries and frameworks, all claiming to address the challenges of developing quick and effective user interfaces (UIs) with smaller package sizes and better performance.
The ongoing struggle among developers and software engineers to determine the best JavaScript framework or library for building UIs is fueled by the consistent introduction of new options.
Some of the libraries and frameworks mentioned are React, VueJS, Angular, Svelte, Nue and Ember, as well as others.
Personally, I think that if you want to create user interfaces, both React and Svelte are great options. Although React is excellent for efficiently building larger applications, Svelte is more appropriate for smaller applications that require high performance.
In this article, I will be examining the differences between Svelte and React, exploring the purposes of Svelte, and comparing it with the React framework. I will respond to queries like:
### The Philosophies.
**React: A Tool for Constructing User Interfaces.**
Created and supported by Facebook, React is a JavaScript library specifically made for constructing user interfaces. In 2013, React transformed developers' approach to UI development by introducing a component-based structure and the idea of a virtual DOM. It focuses on a declarative method, explaining the desired appearance of your UI for a specific state, leaving React to handle the remaining tasks.
**The fundamental principles of react:**
- Component-based architecture involves breaking down the user interface into components that can be reused.
- Declarative UI enables you to define the UI state, with React managing the rendering process.
- Encouraging reusability across the web and mobile, React Native promotes learning once and writing anywhere.
**Svelte: A Tool for Improved Performance via Compilation**
Svelte, created by Rich Harris, is a new innovation that has garnered significant attention for its unique approach. Unlike React, Svelte is not a library or framework; instead, it is a compiler. It shifts most tasks from the browser to the building process, resulting in highly effective vanilla JavaScript code that interacts with the DOM directly.
**The core principles of Svelte are:**
Compile-Time Optimization refers to the practice of transferring responsibilities from the user's side to the compilation stage in order to improve system efficiency while it is running.
Reactive programming eliminates the need for virtual DOM by automatically updating the UI with changes in state. It reduces the quantity of redundant code required to handle state and user interaction.
## Experience in development
**The developer ecosystem of React.**
React has an extensive and well-developed ecosystem. The extensive usage of it leads to a wide array of resources, libraries, and tools at your disposal. React developers have advantages such as a wide range of third-party components, a supportive community, and powerful tools like Create React App, Next.js, and numerous plugins for popular text editors.
React's wide acceptance has led to a larger group of skilled developers and plenty of resources like documentation, tutorials, and community help available. Nevertheless, new learners of JavaScript frameworks may find the learning process challenging, as they must grasp concepts such as JSX, state management (e.g., utilizing Redux or Context API), and hooks, resulting in a steep learning curve.
**The Developer Experience of Svelte**
Svelte aims to streamline the development process by cutting down on boilerplate code and making reactive programming easy to understand. Its structure is straightforward and succinct, enabling programmers to write fewer lines of code to accomplish the same tasks. This could lead to a more satisfying and efficient development process, particularly for those who are new.
The Svelte community is expanding, yet still quite young when compared to React. Even though third-party libraries and resources are limited, the official documentation is top-notch, and the community is lively and inclusive. Emerging tools like SvelteKit aim to offer a more complete development environment.
**Differences between Svelte and React: a head-to-head comparison.**
In this part, we will examine the main distinctions between React and Svelte and draw some comparisons.
1. **Scaffolding and building:** React and Svelte have simple installation and scaffolding procedures, yet React has a more complex ecosystem with additional boilerplate and customization choices compared to Svelte's ease.
2. **Variations**: React uses a virtual DOM to improve updates, whereas Svelte gets rid of the virtual DOM in place of concise code. Both offer benefits based on the specific situation. Both React and Svelte allow for effective component organization, although React has a wider range of tools available in its ecosystem.
3. **Performance**: Svelte changes the DOM directly when state changes occur, whereas React's virtual DOM adds some extra work. Both provide impressive performances that keep getting better.
4. **Documentation**: They both offer fantastic documentation. React has comprehensive documentation and abundant resources, whereas Svelte has extremely concise documentation. React has a vast, established community, whereas Svelte's community is smaller but showing consistent growth.
5. **Learning Curve**: Svelte's reactivity and simplified syntax make its learning curve slightly easier. The wide range of resources available in React's ecosystem makes it worth investing time in.
**Conclusion**
Both Svelte and React possess distinct advantages and are effective instruments for proficient developers. React's established status and vast support system make it a dependable option for big and enduring projects, whereas Svelte's original techniques bring notable speed advantages and an invigorating developer journey.
In the end, your decision between Svelte and React will be based on the needs of your project, team skills, and future objectives. By comprehending the fundamental principles and benefits of each, one can choose wisely according to their requirements. Regardless of whether you opt for the tried-and-tested React or the innovative Svelte, both frameworks have the ability to produce outstanding web applications.
**My expectations for the HNG internship.**
My expectations for the HNG internship are that I'm looking forward to learning and growing as a frontend developer and also collaborating with talented, like-minded individuals.
The opportunity to work with React during the internship is great because it's a very popular and highly used tool in the industry.

**Step 7: Data Preprocessing**
Clean and preprocess the data to make it suitable for training. This involves removing any irrelevant information, handling missing values, and normalizing the data.
**Step 8: Training the Model**
Choose a suitable machine learning algorithm, such as decision trees or neural networks, to train your model. Use the preprocessed data to train the model and evaluate its performance using techniques like cross-validation.
**Step 9: Predicting Vulnerabilities**
Once trained, use the AI model to predict vulnerabilities in new applications. Integrate the AI predictions with your OWASP ZAP scans to enhance the accuracy and efficiency of your security testing.
### Practical Work: Pentesting Life Cycle Phases
Let's dive into a hands-on example of the pentesting life cycle phases:
#### Information Gathering
Start by gathering information about the target application. This includes both passive and active reconnaissance. Use tools like Nmap to find open ports and services.
```bash
nmap <target_ip>
```
Use Nmap's verbose mode to get detailed information about the versions of the services running on the target.
```bash
sudo nmap -sV -A <target_ip> -v
```
#### Threat Modeling
Analyze the traffic flow and identify potential threats. This helps you understand how data moves within the application and where vulnerabilities might exist.
#### Vulnerability Analysis
Use OWASP ZAP to perform a thorough vulnerability analysis. Check for outdated server versions, hidden APIs, and endpoints that might be susceptible to attacks.
#### Exploitation
Attempt to exploit the identified vulnerabilities to understand their impact. This phase involves active attacks to demonstrate the potential damage.
#### Post-Exploitation
After exploiting the vulnerabilities, document the findings and understand the extent of the breach. This phase is crucial for developing remediation strategies.
#### Reporting
Create a detailed report summarizing the findings. Include a description of each vulnerability, the proof of concept (PoC), and recommended solutions.
### Mapping the Network with Nmap
Nmap is a powerful tool for network mapping and port scanning. Here's a basic command to find open ports:
```bash
nmap <ip>
```
For a more detailed scan, use the following command to check service versions and run TCP and UDP scans:
```bash
sudo nmap -sV -A <ip> -v
```
If you are using Windows, Zenmap is a graphical interface for Nmap, but CLI-based Nmap is recommended for more advanced features.
### Detection of Firewalls
To detect firewalls, use Nmap's advanced features:
```bash
sudo nmap -sA -Pn -sV <ip> --reason --packet-trace
```
If the response indicates filtered ports, it means a firewall is present.
### Nmap Scripting Engine
Nmap has a powerful scripting engine that allows you to run predefined scripts:
```bash
sudo nmap -sC <ip>
```
Explore the available scripts in the Nmap script database to enhance your scanning capabilities.
### Firewall Evasion Techniques
If you encounter a firewall, use Nmap's decoy mode to bypass it:
```bash
nmap -D RND:10 <target_ip>
```
This command sends requests from multiple IP addresses, making it harder for the firewall to block you.
### OWASP ZAP: Deep Dive
OWASP ZAP can perform automated and manual security testing. Use the automated scan feature to quickly identify vulnerabilities and customize scan policies to reduce noise.
### Post-Vulnerability Assessment Using ZAP
After using OWASP ZAP, explore additional add-ons to enhance your testing capabilities. Install and configure them to target specific vulnerabilities.
### Authenticated Scans with Burp Suite
For authenticated scans, Burp Suite allows you to provide credentials during the scan setup. This is crucial for testing applications that require user authentication.
### Understanding DNS and DNS Records
When you type a URL like google.com, DNS translates it into an IP address. Understanding DNS records (A, AAAA, CNAME, MX, NS, TXT) is essential for managing domains.
### Tools for DNS Analysis
- **dig**: Use `dig` to find domain information.
```bash
dig google.com
```
- **DNSDumpster**: A web-based tool that visualizes the IP network and domain connections.
### Subdomain Enumeration with Sublist3r
Sublist3r is a CLI tool for finding subdomains of a target. Use it to gather information about additional attack surfaces.
```bash

Angular is a single page... | 0 | 2024-07-02T11:57:04 | https://dev.to/ariya_vijaykumar/browser-refresh-on-click-of-home-button-using-href-2iko | fullstack, angular, angulartestcases, routing | I have a question on writing angular testcases on browser refresh.
Angular is a single page application .there is no browser refresh after logging in. I am building a website with angular in the frontend but not entirely. You will see what i mean in the below example scenario
When I am in Contacts page of the application ,and I click on the logo ,it should navigate me to the homepage always.
I could have simply gone with router link, but there is a catch.
See when Iam in contacts page of the application, the contacts tab is selected in the left-nav-item. When i click on the logo to navigate to the home button, the selection should not be there anymore. means it should work like a browser refresh. For that ,Iam using href instead of router link
<div class="appName-container">
<span class="appName"><a href="home-page">Logo</a></span>
</div>
This will reload the page. See, what i mean when i said not fully angular .
Now my issue is with the testcases.I cant write element.click()
it("should navigate to home page on click of logo",() => {
const element = fixture.nativeElement.querySelector(".appName a") as HTMLElement;
spyOn(window.location, 'reload');
element.click();
expect(window.location.reload).toHaveBeenCalled();
});
here element.click() will reload the page and so the test cases also stop to return Not Found.
I need to trigger the click() here to check if the browser is refreshed.Any suggestion on how to achieve it?

Smart contracts are a revolutionary technology that is changing our understanding of finance and asset management. In this emerging field, BitPower, as a pioneer, has demonstrated the great potential of smart contracts.
BitPower's smart contract technology makes the entire financial ecosystem more transparent, efficient and secure. The cumbersome procedures and human intervention in the traditional financial system are simplified and automated here. With its precise algorithms and tamper-proof characteristics, smart contracts ensure that every transaction is carried out within the rules and cannot be changed or deleted.
In the world of BitPower, smart contracts are at the core of all operations. They not only manage the flow of funds, but also automatically execute predetermined rules and conditions. This means that whether it is lending, investment or dividends, everything is determined by smart contracts, eliminating the risk of human operation. Users only need to deposit assets into BitPower's smart contracts, and the system will automatically complete the corresponding operations according to market conditions and preset rules.
For example, in BitPower's lending system, smart contracts are responsible for matching borrowers and lenders. When users deposit assets as collateral, smart contracts will instantly evaluate their value and calculate the corresponding loan amount and interest rate based on market conditions. This process is fully automated and transparent, and users can check their lending and returns at any time.
Smart contracts also bring inclusiveness to global financial services. No matter where you are, as long as you have an Internet connection, you can participate in the BitPower ecosystem. This decentralized design eliminates the geographical and identity restrictions in the traditional financial system, allowing more people to have the opportunity to enjoy financial services.
BitPower's smart contracts are not limited to financial transactions, but also extend to incentive mechanisms and community building. Users can get corresponding rewards by participating in the promotion and development of the platform. These reward mechanisms are also automatically executed by smart contracts to ensure fairness and transparency.
In general, the application of smart contracts in BitPower not only improves efficiency and security, but also breaks down the barriers of traditional finance and creates a more open and fair financial environment. Through smart contracts, BitPower not only simplifies complex financial operations, but also provides a trustworthy platform for global users, allowing everyone to participate and benefit fairly.
In this new world full of potential, BitPower is gradually realizing its vision through smart contract technology: building a decentralized, transparent and fair global financial ecosystem. This is not just a technological innovation, but also a new definition of the future of finance. | ping_iman_72b37390ccd083e | |
