1,920,572 | Understanding the GENERATED ALWAYS Column Option in PostgreSQL | Understanding the GENERATED ALWAYS Column Option in PostgreSQL The GENERATED ALWAYS column... | 0 | 2024-07-12T07:12:06 | https://dev.to/camptocamp-geo/understanding-the-generated-always-column-option-in-postgresql-oo4 | postgressql, gis | ### Understanding the GENERATED ALWAYS Column Option in PostgreSQL
The `GENERATED ALWAYS` column option in PostgreSQL functions similarly to a view for a table, allowing for on-the-fly calculation of the column's content. This feature is useful for generating computed columns based on expressions.
The syntax is straightforward:
```sql
<column_name> <datatype> GENERATED ALWAYS AS (expression) STORED
```
You define a column name and its datatype, then use the `GENERATED ALWAYS AS` option to specify the expression PostgreSQL should use to generate the column's content. Here’s a geospatial example:
```sql
geom geometry(point, 2154)
GENERATED ALWAYS AS
(ST_Transform(ST_Point(longitude, latitude, 4326), 2154)) STORED
```
In this example, a column named `geom` is created with the datatype `geometry`, representing a point with a projection number 2154 (French projection). The `GENERATED ALWAYS AS` option specifies that this point is generated from two other columns, `longitude` and `latitude`, initially in the "GPS" projection (SRID 4326), and then reprojected to the French projection using `ST_Transform`.
Here’s another example, tailored for a business scenario:
```sql
totalPrice numeric GENERATED ALWAYS AS (unitPrice * quantity) STORED
```
In this case, the `totalPrice` column is generated based on the `unitPrice` and `quantity` columns, calculating the total price of items by multiplying the unit price by the quantity.
According to PostgreSQL documentation, there are specific rules for using the `GENERATED ALWAYS` option:
- The generation expression can reference other columns in the table but not other generated columns.
- Functions and operators used in the expression must be immutable.
- References to other tables are not allowed.
The keyword `STORED` is essential, indicating that the column's value is computed on write and stored on disk. This ensures that the generated values are persistent and do not need to be recalculated on every read, enhancing performance.
By using the `GENERATED ALWAYS` option, you can streamline calculations and maintain consistency within your tables, making it a powerful tool for database management in PostgreSQL. | yjacolin |

1,920,568 | Styling in React | Styling is an essential aspect of building React applications. You have various options for styling,... | 27,566 | 2024-07-12T13:30:00 | https://devship.tech/react/styling | css, react, reactnative, styling | Styling is an essential aspect of building React applications. You have various options for styling, ranging from traditional CSS to modern CSS-in-JS solutions and component libraries. Let's explore some popular approaches:
# Traditional CSS
You can use plain old CSS to style your ReactJS app. Create CSS files and import them into your components. This approach provides familiarity and flexibility but may lack some of the benefits of modern styling solutions.
```css
/* styles.css */
.button {
background-color: blue;
color: white;
padding: 10px;
border: none;
border-radius: 5px;
}
```
```jsx
// App.jsx
import React from "react";
import "./styles.css";
const App = () => <button className="button">Click Me</button>;
export default App;
```
# Inline Styles
Inline styles in React are specified as an object with camelCase properties instead of a CSS string.
```jsx
const buttonStyle = {
backgroundColor: "blue",
color: "white",
padding: "10px",
border: "none",
borderRadius: "5px",
};
const App = () => (
<>
<button style={buttonStyle}>Click Me</button>
<button style={{backgroundColor: "green", color: "white"}}>Click Me</button>
</>
);
export default App;
```
# CSS Modules
CSS Modules allow you to write CSS that's scoped locally to the component, preventing conflicts with styles in other parts of the application.
```css
/* Button.module.css */
.button {
background-color: blue;
color: white;
padding: 10px;
border: none;
border-radius: 5px;
}
```
```jsx
// Button.jsx
import React from "react";
import styles from "./Button.module.css";
const Button = () => <button className={styles.button}>Click Me</button>;
export default Button;
```
# CSS-in-JS Solutions
CSS-in-JS libraries like styled-components, Emotion, and Linaria allow you to write CSS directly within your JavaScript code. This approach offers scoped styles, dynamic styling, and better component encapsulation.
Styled-components is a library for React and React Native that allows you to use component-level styles in your application. It uses tagged template literals to style your components.
```jsx
// Example of using styled-components in React component
import styled from "styled-components";
const StyledButton = styled.button`
background-color: #007bff;
color: #fff;
padding: 10px 20px;
border: none;
border-radius: 5px;
cursor: pointer;
`;
const MyComponent = () => {
return (
<div>
<StyledButton>Click me</StyledButton>
</div>
);
};
```
# Styling Libraries
Several CSS-driven styling libraries are available for React developers. These libraries offer pre-styled and utility classes to quickly build attractive interfaces. Some popular options include TailwindCSS, and react-bootstrap. More on [Styling Libraries](https://devship.tech/react/styling-libraries)
```jsx
// Example of using TailwindCSS in React component
import React from "react";
const MyComponent = () => {
return (
<div>
<button className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
Click me
</button>
</div>
);
};
```
# Component Libraries
Several CSS-driven component libraries are available for React developers. These libraries offer pre-styled components to quickly build attractive interfaces. Some popular options include Chakra UI, MUI, Ant Design, Shadcn, MagicUI, NextUI, StyleX, TailwindUI, HeadlessUI, ArkUI, Reactstrap, Keep React and Aceternity UI. More on [Components Libraries](https://devship.tech/react/components-libraries)
```jsx
// Example of using Chakra UI components in React
import { Button, Heading } from '@chakra-ui/react';
const MyComponent = () => {
return (
<div>
<Heading size="lg">Welcome to Chakra UI</Heading>
<Button colorScheme="blue">Click me</Button>
</div>
);
};
```
# Choosing the Right Approach
The choice of styling approach depends on your project requirements, team preferences, and design goals. Consider factors such as developer experience, maintainability, and performance when selecting a styling solution for your React application. | imparth |

1,920,574 | How to Store Vibration Sensor Data | Part 2 | ReductStore is designed to efficiently handle time series unstructured data, making it an excellent... | 28,044 | 2024-07-12T07:12:42 | https://www.reduct.store/blog/how-to-store-vibration-sensor-data/part-2 | database, vibrationsensor, tutorial | **[ReductStore](https://www.reduct.store/)** is designed to efficiently handle time series unstructured data, making it an excellent choice for storing high frequency vibration sensor measurements.
This article is the second part of **[How to Store Vibration Sensor Data | Part 1](https://www.reduct.store/blog/how-to-store-vibration-sensor-data)**,
where we discussed the benefits of storing both raw measures and pre-processed metrics, the advantages of time series databases, and efficient storage and replication strategies.
In this post, we'll dive into a practical example of storing and querying vibration sensor readings using ReductStore and Python.
To follow along, you can find the full source code for this example at **[GitHub's reduct-vibration-example repository](https://github.com/reductstore/reduct-vibration-example)**.
Our example will show you how to:
1. Store simulated sensor values in 1-second chunks
2. Compute and store associated labels for each chunk
3. Query and retrieve stored measurements within a specified time range
4. Set up replication using the ReductStore web console
## Setting Up the Environment
Before we dive into the code, let's set up our environment.
We'll be using Docker to run ReductStore and Python for our client application.
### ReductStore Setup
Create a `docker-compose.yml` file with the following content:
```yaml
version: '3.8'
services:
reductstore:
image: reduct/store:latest
ports:
- "8383:8383"
volumes:
- data:/data
environment:
- RS_API_TOKEN=my-token
volumes:
data:
driver: local
```
Then we ca run ReductStore with:
```bash
docker compose up -d
```
This will start ReductStore on port 8383 with a simple API token for authentication.
### Python Setup
Make sure you have Python 3.8+ installed in your environment.
Then simply install the necessary libraries for our example using pip:
```bash
pip install reduct-py numpy
```
Now that we have our environment set up, let's dive into the code.
## Code Structure and Functionality
Let's break down the main components of our Python script:
### Connecting to ReductStore
```python
async def setup_reductstore() -> Bucket:
client = Client("http://localhost:8383", api_token="my-token")
return await client.create_bucket("sensor_data", exist_ok=True)
```
This function establishes a connection to ReductStore and creates (or gets) a bucket named `sensor_data`.
A bucket is a logical container for storing time series data, and each bucket can contain multiple entries (e.g., `vibration_sensor_1`, `vibration_sensor_2`).
### Generating Simulated Sensor Data
```python
def generate_sensor_data(frequency: int = 1000, duration: int = 1) -> np.ndarray:
t = np.linspace(0, duration, frequency * duration)
signal = np.sin(2 * np.pi * 10 * t) + 0.5 * np.random.randn(len(t))
return signal.astype(np.float32)
```
This function generates a simulated sensor signal: a simple sine wave with added noise.
In a real-world scenario, you would replace this with actual sensor readings.
As we saw in **[How to Store Vibration Sensor Data | Part 1](https://www.reduct.store/blog/how-to-store-vibration-sensor-data)**, it's beneficial to divide the data into chunks for more efficient storage and querying.
In this example, we generate 1 second of data at a time (1,000 samples at 1 kHz), that we'll store as a single entry in ReductStore.
### Calculating Metrics
```python
def calculate_metrics(signal: np.ndarray) -> tuple:
rms = np.sqrt(np.mean(signal**2))
peak_to_peak = np.max(signal) - np.min(signal)
crest_factor = np.max(np.abs(signal)) / rms
return rms, peak_to_peak, crest_factor
```
We calculate three common metrics for our signal: RMS (Root Mean Square), Peak-to-Peak, and Crest Factor.
### Packing Binary Data
```python
def pack_data(signal: np.ndarray) -> bytes:
fmt = f">{len(signal)}f"
return struct.pack(fmt, *signal)
```
This function uses the `struct` module to pack our numpy array into a binary format, specifically with the format string `">1000f"` (more details on this below).
You may be wondering why we don't use numpy's `tobytes()` method. While `tobytes()` is convenient, it offers limited control over the byte format,
which can lead to compatibility problems when reading the data on different devices.
The `struct` module, on the other hand, allows us to specify byte order and data type, preserving consistent data representation and avoiding compatibility problems.
The format string `">1000f"` is explained as follows, based on the **[struct module documentation](https://docs.python.org/3/library/struct.html#struct-format-strings)**:
- `>` indicates big-endian byte order, with the most significant byte (leftmost byte) stored first, which is common in network communications.
- `1000` is the number of elements in the array (1000 samples).
- `f` is the data type (float) for each element, with a default size of 4 bytes.
The choice of binary data depends on your specific requirements, if you are using specific hardware or software that requires a different format, you can adjust the format string accordingly.
Some restricted embedded systems may require a specific byte order or data type, so it's important to understand the format requirements of your architecture.
### Storing Data in ReductStore
```python
HIGH_RMS = 1.0
HIGH_CREST_FACTOR = 3.0
HIGH_PEAK_TO_PEAK = 5.0
async def store_data(
bucket: Bucket,
timestamp: int,
packed_data: bytes,
rms: float,
peak_to_peak: float,
crest_factor: float,
):
labels = {
"rms": "high" if rms > HIGH_RMS else "low",
"peak_to_peak": "high" if peak_to_peak > HIGH_PEAK_TO_PEAK else "low",
"crest_factor": "high" if crest_factor > HIGH_CREST_FACTOR else "low",
}
await bucket.write("sensor_readings", packed_data, timestamp, labels=labels)
```
This is where we store our packed chunk of data, along with labels that indicate whether each metric is high or low.
This allows us to later replicate and filter data based on these metrics.
The hard-coded thresholds for high RMS, peak-to-peak, and crest factor values are for demonstration purposes.
These values should be determined based on your specific sensor and application requirements and can be adjusted using environmental variables or configuration files.
### Querying and Retrieving Data
```python
async def query_data(bucket: Bucket, start_time: int, end_time: int):
async for record in bucket.query(
"sensor_readings", start=start_time, stop=end_time
):
print(f"Timestamp: {record.timestamp}")
print(f"Labels: {record.labels}")
data = await record.read_all()
num_points = len(data) // 4
fmt = f">{num_points}f"
signal = struct.unpack(fmt, data)
signal = np.array(signal, dtype=np.float32)
print(f"Number of data points: {num_points}")
print(f"First few values: {signal[:5]}")
print("---")
```
This function shows how to query data within a given time range and unpack the binary data back into the original Numpy array.
1. The `read_all()` method reads the whole chunk of data at a given timestamp.
2. The length of the data is divided by 4 to get the number of float values, since each float is 4 bytes long.
3. The same format string used to pack the data is used to unpack the data to ensure that the data is interpreted correctly.
4. The unpacked data is then converted back to a Numpy array, which is more convenient for further processing.
### Main Execution
```python
async def main():
bucket = await setup_reductstore()
# Store 5 seconds of data
for _ in range(5):
timestamp = int(time.time() * 1_000_000)
signal = generate_sensor_data()
rms, peak_to_peak, crest_factor = calculate_metrics(signal)
packed_data = pack_data(signal)
await store_data(
bucket, timestamp, packed_data, rms, peak_to_peak, crest_factor
)
await asyncio.sleep(1)
# Query the stored data for the last 5 seconds
end_time = int(time.time() * 1_000_000)
start_time = end_time - 5_000_000
await query_data(bucket, start_time, end_time)
```
This is the main execution flow of our script, which demonstrates the complete data flow:
1. We connect to ReductStore and create a bucket.
2. We store 5 seconds in chunks of 1 second data. Each timestamp is generated using the current time in microseconds.
3. We query the stored data for the last 5 seconds and print the results.
Now that we are able to store and query vibration sensor data, let's explore how to duplicate important data using ReductStore's replication feature.
## Replication with ReductStore Web Console
In addition to storing and querying data, we can also set up replication to duplicate our sensor data across multiple ReductStore instances.
Replication tasks can be configured in a variety of ways, such as
- Replicate all data from a source bucket to a target bucket (e.g. `sensor_data` to `backup_data`)
- Replicate only specific entries, e.g. `sensor_readings`.
- Replicate data based on labels, e.g. replicate only data with `high` RMS values to `high_peak_to_peak` bucket (as we'll do in this example).
The replication task can be set using client libraries, HTTP API, CLI, provisioning, or the ReductStore web console.
In this example, we'll use the web console for simplicity, but you can also refer to the **[Replication Guide](https://www.reduct.store/docs/guides/data-replication)** for more details.
So the bucket structure that we'll set up is as follows:
- `sensor_data` bucket contains all sensor readings under the entry `sensor_readings`.
- `high_peak_to_peak` bucket will contain only the sensor readings with high peak-to-peak values under the same entry name `sensor_readings`.
Here's how to set it up:
1. Access the ReductStore web console (typically at `http://localhost:8383` if running locally).
2. Navigate to the "Replications" section to create a new replication with the "+" button.
3. Enter a name for your replication task and add the following details:
- Choose your source bucket (in this case, `sensor_data`).
- Enter the destination bucket name (e.g., `high_peak_to_peak`)
- Enter the details for your destination ReductStore instance (in this case, the same instance for demonstration purposes `http://localhost:8383`)
- Enter the destination token (in this case, the same token `my-token` for demonstration purposes)
- Then, set up filters based on labels to replicate only data with `high` RMS.
4. Click "Create" to start the replication process.
With this new replication task, all new data from the `sensor_data` bucket with the label `peak_to_peak = high` will be replicated to the `high_peak_to_peak` bucket.
On a side note, only new data will be replicated, so you can set up replication tasks at any time without worrying about duplicating existing data.
## Conclusion
We explored a practical implementation of storing and querying vibration sensor data using ReductStore and Python. Here's a summary of what we covered:
1. We set up a ReductStore instance using Docker and installed the necessary Python libraries.
2. We simulated vibration sensor data, calculated key metrics (RMS, peak-to-peak, and crest factor), and packaged the data into a binary format that we can configure to ensure the data can be read by other devices.
3. We stored the data in ReductStore, along with labels indicating whether each metric was high or low.
4. We demonstrated how to query the stored data and unpack it back into a usable format.
5. Finally, we explored how to set up replication using the web console so that we could copy high peak-to-peak metrics into a separate bucket.
While we used simulated data here, the same approach works for real sensor readings.
This setup can serve as a starting point for building your own vibration data management system, which you'll likely need to tailor to your specific needs and hardware.

1,920,630 | Optimizing ETL Processes for Efficient Data Loading in EDWs | In today's data-driven world, the ability to efficiently and accurately move data from various... | 0 | 2024-07-12T07:32:11 | https://dev.to/ovaisnaseem/optimizing-etl-processes-for-efficient-data-loading-in-edws-96n | emterprisedatawarehouse, etl, datascience, bigdata | In today's data-driven world, the ability to efficiently and accurately move data from various sources into an [enterprise data warehouse](https://www.astera.com/type/blog/enterprise-data-warehouse/?utm_source=https%3A%2F%2Fdev.to%2F&utm_medium=Organic+Guest+Post) (EDW) is crucial for enabling robust business intelligence and analytics. ETL (Extract, Transform, Load) processes play a pivotal role in this data integration, ensuring that data is collected, cleaned, and made available for analysis. Optimizing these ETL processes can lead to significant improvements in data quality, processing speed, and overall system performance. This article explores best practices and strategies for enhancing ETL efficiency in EDWs.
## Understanding ETL Processes
ETL processes are composed of three primary stages:
- **Extract:** Data is retrieved from various source systems, which can include databases, flat files, APIs, and more.
- **Transform:** Extracted data is cleaned, formatted, and transformed to fit the schema of the target EDW.
- **Load:** Transformed data is loaded into the EDW for storage and subsequent analysis.
Each of these stages can be optimized to ensure smooth and efficient data loading into the EDW.
## Challenges in Optimizing ETL Processes
While optimizing ETL processes can bring numerous benefits, several challenges may arise:
**1. Data Volume and Velocity**
As organizations generate and collect data at unprecedented rates, handling large volumes of data in real-time can be daunting. Ensuring that ETL processes keep up with the velocity of incoming data without compromising performance is a significant challenge.
**2. Heterogeneous Data Sources**
Integrating data from diverse sources can complicate ETL processes. Ensuring consistent and accurate data extraction and transformation from these heterogeneous sources requires sophisticated ETL tools and strategies.
**3. Complex Transformations**
Some data transformations can be highly complex, involving multiple steps and intricate logic. Optimizing these transformations to ensure they are both efficient and accurate can be challenging, particularly when dealing with legacy systems or poorly documented data sources.
**4. Maintaining Data Quality**
Ensuring high data quality is crucial, but it can be difficult to manage as data flows through various stages of the ETL process. Identifying and rectifying data quality issues early in the process is essential, yet often challenging, especially with large and complex datasets.
**5. Resource Management**
Balancing resource allocation to prevent bottlenecks and ensure optimal performance can be tricky. ETL processes often compete for system resources, and managing this competition to avoid performance degradation requires careful planning and monitoring.
**6. Compliance and Security**
Adhering to regulations and ensuring data security throughout the ETL process adds another layer of complexity. Implementing robust security measures and maintaining compliance can slow down ETL processes and require additional resources.
**7. Scalability and Flexibility**
As data needs grow and change, ensuring that ETL processes are scalable and flexible enough to adapt without significant rework is challenging. Building an ETL architecture that can evolve with the organization’s needs requires foresight and robust design principles.
**8. Technical Debt**
Over time, ETL processes can accumulate technical debt, particularly if quick fixes are applied without considering long-term impacts. Refactoring and optimizing legacy ETL processes to eliminate inefficiencies can be a time-consuming and complex task.
## Best Practices for Optimizing ETL Processes
**1. Incremental Data Loading**
Instead of performing full data loads, which can be time-consuming and resource-intensive, incremental loading only processes new or changed data. This approach reduces the amount of data handled in each ETL cycle, leading to faster processing times and reduced system strain.
**2. Parallel Processing**
Leveraging parallel processing allows multiple ETL tasks to run simultaneously, significantly speeding up the data transformation and loading stages. Modern ETL tools often support parallel processing capabilities, which can be configured to maximize resource utilization.
**3. Efficient Data Transformation**
Data transformation can be the most time-consuming part of the ETL process. To optimize this stage:
Push-down Transformation: Perform transformations within the source or target database whenever possible, utilizing their processing power.
Avoid Unnecessary Transformations: Only apply transformations that are necessary for the target schema and business requirements.
**4. Scalable Infrastructure**
Ensure that your ETL infrastructure can scale to handle increasing data volumes. This includes using scalable cloud-based platforms that can dynamically allocate resources based on demand, thereby maintaining performance during peak loads.
**5. Data Quality Management**
Implement data quality checks early in the ETL process to identify and correct errors before they propagate through the system. This includes validating data types, formats, and ranges, as well as deduplicating records.
**6. Efficient Use of Storage**
Use efficient storage formats like columnar storage for analytical queries, which can improve read performance. Additionally, employ data partitioning to manage large datasets more effectively, allowing ETL processes to target specific partitions instead of scanning entire tables.
**7. Monitoring and Logging**
Implement comprehensive monitoring and logging to track ETL performance and identify bottlenecks. Tools that provide real-time insights into ETL processes can help quickly pinpoint issues and optimize workflows.
**8. Automated ETL Scheduling**
Automate ETL job scheduling to ensure timely and consistent data loading. Use scheduling tools that can handle dependencies and trigger processes based on specific conditions or events.
**9. Metadata Management**
Maintain detailed metadata to understand the origin, transformation, and lineage of data. This transparency helps in troubleshooting issues and ensuring data integrity throughout the ETL process.
**10. Security and Compliance**
Ensure that ETL processes comply with relevant data security and privacy regulations. Encrypt data and implement access controls to protect data during extraction, transformation, and loading.
## Conclusion
Optimizing ETL processes is essential for maintaining an efficient and high-performing enterprise data warehouse. By adopting best practices such as incremental loading, parallel processing, efficient data transformation, and scalable infrastructure, organizations can enhance their ETL workflows. Improved ETL processes not only ensure faster data availability but also enhance the overall quality and reliability of the data, enabling better business insights and decision-making. As data volumes continue to grow, ongoing optimization and innovation in ETL processes will remain a critical focus for organizations seeking to leverage their data assets effectively. | ovaisnaseem |
1,920,631 | 3+1 Best Simple Notion Tips to Boost Productivity | Hello, I hope you are doing well. In today’s article, I will share some use cases that I take... | 0 | 2024-07-12T07:34:12 | https://dev.to/mammadyahyayev/31-best-simple-notion-tips-to-boost-productivity-287h | productivity, discipline, notion | 
Hello, I hope you are doing well. In today’s article, I will share some use cases that I take advantage of them frequently on Notion.
Notion probably most used productivity tools around the world in these days. There are tons of things you can do in Notion, such as managing your time, creating todo lists, managing your projects, taking notes, etc.
## How to Visualize Math Equations?
I am studying Probability and Statistics in the university for my master degree and there are huge amount of formulas and they are hard to remember. Thus, I decide to put them down to Notion.
For instance, if you want to represent following formula in Notion, you can make it by doing the thing that are listed below.
1. Type **/math**
2. Select ‘Inline Equation‘
3. Type followings in the opened dialog
`P(A ∩ B) \above{2pt} P(B)`
The expression doesn’t require explanation, the only thing that might confuse you is {2pt}. It gives thickness to the Vinculum (aka. fraction bar).
## How to Learn a New Language with Notion?
Language learning process requires so much practice and effort. Sometimes the process can be quite challenging, if you have no clue how to cope with the process, I will share the technique that I’ve learned from [Robin MachPherson](https://www.youtube.com/c/RobinMacPhersonFilms). Follow the steps.
1. Create new page in Notion and call it Language Learning (you can call any name you want)
2. Create subpages inside of the Language Learning page. For instance, English, German, Spanish and so on
3. Create table inside the subpages (English, German, Spanish), and add 2 columns. First column will be the language that you are currently learning, the latter column will be your mother language.
4. Add sentences and phrases that you hear every day, along with their translations.
That’s it, your language learning process is planned.
If you want to learn the technique in details, watch this [video](https://www.youtube.com/watch?v=Ec5tLVeZrFM&t=562s).
## How to Track Book Reading Progress in Notion?
I really enjoy to note down phrases from the books that I read, at the same time it is good to see the progress on the book. I create seperate page for books on Notion.
In first column, I keep the books that I planned to read in the future, the middle column contains books that I am reading currently, the last column shows completed books. Let’s look at the book individually.
The properties explain themselves, the last property is a bit different the others. It shows, 34% of the book’s content has been read. This is the unique formula, applied to all books in the page.
It is good to see the progress, because it attract me to complete book. I will show you how to make a property like this. Follow the steps
1. Add a new property with Formula
2. Add the following into Formula
`round(prop("Current Page") / prop("Page Count") * 100)`
These are the dynamic values, prop(“Current Page”) will be replaced with 372. And this formula will be applied to all the books in the page dynamically.
You may ask why did we use dynamic properties, because the progress or pages are different in each book, if you type them without using dynamic properties, it will be the same value in each book. These are the properties that I want to see on every book, of course, you can add multiple properties.
## How to Manage Blog Contents?
If you are a content creator, managing your articles, videos or post might be a difficult process.
In the image above, you can see some of my contents. In each content contains a page that allow me to write ideas or things that I am going to share on blog.
The template is not only for blog contents, but also for all of your social media posts, or youtube contents.
As you can see, there are 5 properties. Their names explain themselves, and no need to mention. However, the only thing I want to mention here is Post **Status**. There are 4 statuses.
1. **Not Started** — In this phase, I write all of the ideas, notes.
2. **In Progress** — this status indicates, I am currently writing the article. I try to compete the article in 2 days or as soon as possible.
3. **Need to Update** — In this phase, I’ve already written and published the article. After I come up with new idea, I changed status to ‘Need to Update’
4. **Done** — this status indicates, I finished the article
You can add more properties into this template such as link of the article, author, how many words have written and so on. However those properties are enough for my case.
## Conclusion
I have listed my use cases here, so please add yours to the comment section, so everyone can benefit.
See you soon in upcoming articles. Take care of yourself.

When companies begin to use big data, they often face significant difficulties in organizing, storing, and interpreting the vast amounts of data collected.
Applying traditional data modeling techniques to big data can lead to performance concerns, scalability issues, and inefficiencies because they were created for more organized and predictable data environments.
These problems arise from the mismatch between traditional approaches and the dynamic nature of big data, causing decisions to take longer, be more expensive, and data not be used appropriately.
## The Challenges of Big Data
The three characteristics that define big data are volume, velocity, and variety. It is important to understand these aspects to deal with the specific obstacles they pose.
**Volume**
It’s amazing how much data is generated these days. Businesses collect data from a variety of sources, such as social media interactions, sensors, and consumer transactions. Scalable storage systems and data models that can effectively manage large datasets without compromising performance are essential to manage this vast amount of data.
**Velocity**
Another significant constraint is the rate at which data is created and must be analyzed. It is often necessary to process data in real time or near real time to quickly gain meaningful insights. The rapid flow of data often overwhelms traditional data models, which are built for slow, batch processing and causes bottlenecks and delays.
**Variety**
Big data can be found in many different forms, including unstructured data such as text, photos, and videos, as well as structured data found in databases. This requires adaptable models that can take into account different formats and structures to integrate and analyze these disparate data types. Traditional models find it difficult to accommodate this diversity because they are generally inflexible and schema-dependent.

## Top 3 Big Data Modelling Approaches
**1. Dimensional Modeling**
Data warehouses are organized using the design principle of dimensional modeling to facilitate effective retrieval and analysis. It is mostly used in business intelligence and data warehousing contexts to improve end users’ access to and understanding of data. This architecture makes data organization simple and quick by grouping data into fact and dimension tables.
**KEY COMPONENTS**
**Facts:** These are the main tables in the dimensional model that contain quantitative information for analysis, such as number of transactions, sales revenue, and quantity sold.
**Dimensions:** These tables provide fact-related descriptive features such as time, location, product specifications, and customer data.
Measures: Measurement fact tables contain numerical data that is analyzed, such as total sales amount or number of units sold.
**2. Data Vault Modeling**
A database modeling technique called “data vault modeling” was created to offer long-term historical data storage from several active systems. It is appropriate for big data situations since it is extremely scalable and flexible to changing business needs.
**KEY CONCEPTS**
**Hubs:** Have unique IDs and act as a representation of important corporate entities such as customers and products.
**Links:** Record connections between hubs, such as sales exchanges that connect goods to customers.
**Satellites:** Track descriptive data changes over time, such as modifications to customer addresses.
**Star Schema Design**
Star schema is a popular data modeling technique in data warehousing and business intelligence used to organize data to maximize query performance and simplify analysis. It is distinguished by a star-shaped primary fact table surrounded by multiple dimension tables.

To enable Remote Desktop Protocol (RDP) on an Azure Virtual Machine running Linux, you will need to install a desktop environment and an RDP server like xRDP. Here are the steps to do that:
### Step 1: Create and Access Your Azure VM
1. **Create the VM**:
- Log in to your [Azure Portal](https://portal.azure.com/).
- Create a new VM, select the appropriate options for your needs (OS, size, etc.).
2. **Access the VM**:
- Once your VM is created, access it via SSH:
```sh
ssh your-username@your-vm-ip-address
```
### Step 2: Install Desktop Environment and xRDP
1. **Update the package list**:
```sh
sudo apt update
```
2. **Install a desktop environment (e.g., Xfce)**:
```sh
sudo apt install xfce4 xfce4-goodies
```
3. **Install xRDP**:
```sh
sudo apt install xrdp
```
4. **Enable and start the xRDP service**:
```sh
sudo systemctl enable xrdp
sudo systemctl start xrdp
```
### Step 3: Configure xRDP
1. **Add the xRDP user to the `ssl-cert` group**:
```sh
sudo adduser xrdp ssl-cert
```
2. **Set Xfce as the default session for xRDP**:
```sh
echo xfce4-session >~/.xsession
```
3. **Restart the xRDP service**:
```sh
sudo systemctl restart xrdp
```
### Step 4: Open Port 3389 on Azure Network Security Group (NSG)
1. **Go to the Azure Portal**.
2. **Navigate to your VM** and select `Networking` under `Settings`.
3. **Add an inbound port rule** for port 3389.
### Step 5: Connect to Your Linux VM via RDP
1. **Open Remote Desktop Connection** on your local machine.
2. **Enter the IP address** of your Azure VM.
3. **Log in using your username and password** created on the VM.
You should now be able to access your Linux VM using RDP. | karunakaran |

This is because of the... | 0 | 2024-07-12T07:48:55 | https://dev.to/ragavi_document360/the-era-of-llm-agents-next-big-wave-in-knowledge-management-3mm3 | Gartner predicts that search engine volume will drop up to 25% in 2026. This is because of the emergence of GenAI-powered search engines. Customers prefer to use a ChatGPT-like interface to seek answers, which are powered by Large Language Models (LLMs) for their convenience and ease of use. Eventually, customers will abandon search engines! Many companies utilize GenAI-based agents such as chatbots, and assistive search to provide rich customer experience.
The appetite for these GenAI tools is growing, and many people are adopting these technologies faster. At Document360, we have adopted GenAI capabilities such as Eddy AI to provide enhanced search experience and content tools to help technical writers increase their productivity.
## Evolution of GenAI Search & Chatbots
The Retrieval Augmented Generation (RAG) approach underpins how the GenAI search engine works. The need for a conversational interface leads to many companies adopting open-source frameworks such as LangChain. Both GenAI-powered search engines and chatbots are gaining a lot of traction amongst the new wave of customers who are tech-savvy and want to get things done quicker! benefits of these tools are multi-fold such as
- Helps to learn better through iterative probing
- Assists in producing accurate answers to customer questions
- Feels natural to have a conversation
The enterprise has to empower those customers looking to resolve their queries themselves with the right tools such as a chatbot. GenAI search & Chatbots are predominantly used by enterprise organizations in deflecting support tickets. Many enterprises are finding success in increased customer satisfaction scores after the introduction of chatbots inside their products and information portals.
## Beyond AI LLM Agents Will Shape the Future
The LLM agents are poised to become the next big thing. These agents may be tasked to involve human beings before making decisions, thus human-in-the-loop principles should be applied while designing these systems. The future is exciting given the rise of LLM agents who are programmed to perform tasks, make decisions, and communicate with other LLM agents for information exchange. They can leverage collaborative intelligence to undertake sophisticated tasks quickly and easily.
Imagine asking a GenAI-powered search engine a “How-to” procedure. For example, in docs.document360.com, you can ask Eddy AI, “How to insert a business glossary term into an article”
Eddy AI produces four sequential steps to accomplish this task, which may or may not need human input. If a GenAI-based search produces these steps, an LLM agent can understand and execute them inside the product. This can be accomplished in two ways.

1,920,758 | Introduction to GBase 8c B Compatibility Library (2) | With the support of the Dolphin plugin, the GBase 8c B Compatibility Database (dbcompatibility='B',... | 0 | 2024-07-12T07:52:17 | https://dev.to/congcong/introduction-to-gbase-8c-b-compatibility-library-2-2bcn | database | With the support of the Dolphin plugin, the GBase 8c B Compatibility Database (dbcompatibility='B', hereafter referred to as the B compatibility library) has greatly enhanced its compatibility with MySQL in terms of data types. Here is a look at the common data types:
## Numerical Types
Compared to the native GBase 8c syntax, Dolphin makes several modifications to numerical types:
1. **INT/TINYINT/SMALLINT/BIGINT**:
- Added support for optional modifiers (n), allowing the usage of TINYINT(n)/SMALLINT(n)/BIGINT(n). The modifier n has no practical significance and does not affect any behavior.
2. **MEDIUMINT(n)**:
- A new data type added as an alias for INT4. The modifier n has no practical effect. It occupies 4 bytes of storage space with a range of -2,147,483,648 to +2,147,483,647.
3. **FIXED[(p[,s])]**:
- Introduced as an alias for the NUMERIC type. Users can specify precision. Every four decimal digits occupy two bytes, plus an additional eight-byte overhead for the entire data. Without specified precision, it supports a maximum of 131,072 digits before the decimal point and 16,383 digits after.
4. **float4(p[,s])**:
- A new addition, equivalent to dec(p[,s]).
5. **double**:
- Introduced as an alias for float8.
6. **float4/float**:
- Added support for optional modifiers (n), allowing the usage of float4(n)/float(n). When n is between [1,24], it represents a single-precision floating point; when n is between [25,53], it represents a double-precision floating point.
7. **decimal/dec/fixed/numeric**:
- When precision is not specified, the default precision is (10,0), meaning 10 total digits with 0 decimal places.
8. **UNSIGNED INT/TINYINT/SMALLINT/BIGINT**:
- Compared to regular integers, the highest bit is a digit bit rather than a sign bit. Additionally, in GBase 8c, TINYINT is unsigned by default, whereas in the B library, it is signed by default.
9. **zerofill attribute modifier**:
- Only syntactically supported with no actual zero-filling effect. Equivalent to the UNSIGNED modifier.
10. **cast function type conversion**:
- Added parameters signed/unsigned. `cast as unsigned` converts the type to uint8, and `cast as signed` converts the type to int8.
11. **float(p,s), double(p,s), real(p,s), double precision(p,s)**:
- These syntaxes are roughly equivalent to dec(p,s). Unlike dec(p,s), the p and s for float(p,s), real(p,s), and double precision(p,s) must be integers, while double(p,s) is entirely equivalent to dec(p,s). The rounding method used is round-half-up.
**Table 1 Integer Types**
| Name | Description | Storage Space | Range |
|---------------|------------------------------------------------------|---------------|---------------------------------|
| TINYINT(n) | Tiny integer, alias for INT1. n has no practical effect. | 1 byte | -128 to +127 |
| SMALLINT(n) | Small integer, alias for INT2. n has no practical effect. | 2 bytes | -32768 to +32767 |
| INTEGER(n) | Common integer, alias for INT4. n has no practical effect. | 4 bytes | -2147483648 to +2147483647 |

Rounding mode is round half up. | User-declared precision. Each four decimal digits occupy two bytes, plus an additional overhead of eight bytes for the entire data. | |
## Character Types
Compared to the native GBase8c syntax, dolphin has made the following modifications to character types:
1. Modified the meaning of n in CHARACTER/NCHAR types, where n indicates the character length instead of the byte length.
2. All character data types ignore trailing spaces when compared, such as in `WHERE` clause filtering or `JOIN` conditions. For example, `'a'::text = 'a'::text` evaluates to true. Note that for VARCHAR, VARCHAR2, NVARCHAR, TEXT, and CLOB types, trailing spaces are ignored in hash joins and hash aggregates only when the GUC parameter `string_hash_compatible` is set to `on`.
3. Added `NATIONAL VARCHAR(n)`, an alias for the `NVARCHAR2(n)` type, where n indicates the character length.
4. Added support for an optional modifier (n) in `TEXT`, allowing the usage of `TEXT(n)`. The n has no practical significance and does not affect any behavior.
5. Added `TINYTEXT(n)`, `MEDIUMTEXT(n)`, and `LONGTEXT(n)` data types, which are aliases for `TEXT`. The n has no practical significance and does not affect any behavior.
**Table 4 Character Types**
| Name | Description | Storage Space |
|---------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------|--------------------------------------|
| CHAR(n) <br> CHARACTER(n) <br> NCHAR(n) | Fixed-length string, padded with spaces if necessary. n specifies the character length. If n is not specified, the default length is 1. | Up to 10MB. |
| NATIONAL <br> VARCHAR(n) | Variable-length string. Alias for NVARCHAR2(n) type. n specifies the character length. | Up to 10MB. |
| TEXT(n) <br> TINYTEXT(n) <br> MEDIUMTEXT(n) <br> LONGTEXT(n) | Variable-length string. n has no practical meaning and does not affect any behavior. | Up to 1GB-1, but considering column descriptor header size and tuple size limitations, the maximum size may be less than 1GB-1. |
## Examples
**1. Create a test table and insert data**
```sql
CREATE TABLE char_type_t1
(
CT_COL1 CHARACTER(4),
CT_COL2 TEXT(10),
CT_COL3 TINYTEXT(11),
CT_COL4 MEDIUMTEXT(12),
CT_COL5 LONGTEXT(13)
);
```
**2. Check the table structure**
```sql
\d char_type_t1
```
Result:
```
Table "public.char_type_t1"
Column | Type | Modifiers
--------+--------------+-----------
CT_COL1 | character(4) |
CT_COL2 | text |
CT_COL3 | text |
CT_COL4 | text |
CT_COL5 | text |
```
**3. Insert data into the table**
```sql
INSERT INTO char_type_t1 VALUES ('4 characters');
```
**4. Query the data**
```sql
SELECT CT_COL1, length(CT_COL1) FROM char_type_t1;
```
Result:

Once the consumption in kWh is recorded, charges are calculated based on the applicable tariff rates. Additional charges, such as taxes or surcharges, may also apply.
- **Billing Cycles and Invoicing:**
Utility companies typically issue bills periodically (e.g., monthly) to customers based on their consumption during a specific billing cycle. Bills detail the amount of electricity consumed, applicable charges, and payment due dates.
**Factors Affecting Electricity Bills**
Several factors can influence the amount of an electricity bill:
- Consumption Levels: Higher electricity consumption results in higher bills.
- Tariff Structures: Different tariffs can significantly impact the cost per unit of electricity consumed.
- Seasonal Variations: Electricity usage may fluctuate based on seasonal factors such as heating or cooling needs.
- Energy Efficiency: Adopting energy-efficient practices and technologies can help reduce overall consumption and lower bills.
**Understanding Your Electricity Bill**
To interpret your electricity bill accurately, it's essential to understand the breakdown of charges and the terms used:
- Unit Price: The cost per kWh of electricity consumed.
- Fixed Charges: Base fees or minimum charges applied regardless of consumption.
- Taxes and Surcharges: Additional fees imposed by regulatory authorities or utility providers.
**Conclusion**
Understanding electricity billing is crucial for consumers and businesses to manage energy consumption effectively and budget accordingly. By grasping the principles of how electricity bills are calculated, you can make informed decisions to optimize energy usage and reduce costs.

Quelle est la différence entre **??** et **||** ?
## Nullish Coalescing Operator - ??
De son doux nom français **“Opérateur de coalescence des nuls”**, **a ?? b** permet de renvoyer le terme **a** si ce dernier n’est pas ni **null** ni **undefined**. Dans le cas inverse l’opérateur renvoie le terme **b.**
Voici un exemple qui permet de redéfinir cet opérateur en JavaScript.
```jsx
const result = a ?? b
```
```jsx
const nullishCoalescingOperator = (a, b) => {
if (a !== null && a !== undefined) {
return a
}
return b;
}
const result = nullishCoalescingOperator(a,b);
```
## Logical Or Operator - ||
L’**opérateur OU logique** est similaire à l’opérateur de coalescence des nuls à l’exception que ce dernier test si le terme **a** est **falsy**.
Pour rappel voici une liste non exhaustive des valeurs falsy en JavaScript :
- null
- undefined
- false
- NaN
- 0
- “”
Voici un exemple qui permet de redéfinir cet opérateur en JavaScript.
```jsx
const result = a || b
```
```jsx
const orOperator = (a,b) => {
if (a) {
return a;
}
return b;
}
```

1,920,775 | Authentication and Authorization in .NET Core | Summary: As the tech business development marketplace evolves with the days the security risks... | 0 | 2024-07-12T08:22:47 | https://dev.to/jemindesai/authentication-and-authorization-in-net-core-3a7h | authentication, authorization, dotnetcore, positiwise | **Summary:** As the tech business development marketplace evolves with the days the security risks related to it take a surge. This leads to the need for restricting access to a few resources within the application to authorized users only as it allows the server to determine which resources the user should have access to. In this blog post, we will have a deeper look into the Authentication and Authorization in .NET Core to ensure the safety and security of your [.NET business application](https://positiwise.com/technologies/dot-net-development).
## Understanding Authentication in .NET Core
Authentication in .NET Core refers to the process of determining the identity of a user. Authorization, on the other hand, refers to the process of determining whether a user has access to a resource. Explaining it further Authentication in [.NET Core](https://positiwise.com/technologies/dot-net-development) is a process where the identity of the users is verified by those who wish to attempt to access an application or a system. Authentication further ensures that the real user only is accessing the said data. In .NET Core Authentication generally requires validating the user credentials such as usernames, and passwords, against a trusted source. Such as a database or an identity provider.
Authorization on the other hand is the process of determining the actions authenticated that users can perform within the application. It ensures that the authenticated users here have access to resources and functionalities that align with their assigned or granted roles and permissions.
## Implementing the JWT Authentication .NET Core
The JSON Web Tokens or JWT are a renowned way to implement authentication within modern web applications referring to their stateless nature and scalability. In .NET Core JWT authentication requires generating the token upon successful login and validating it with each subsequent request.
You can refer to the steps given below to implement JWT authentication in .NET Core:
**Step 1:** Install the required packages
```
dotnet add package Microsoft.AspNetCore.Authentication.JwtBearer
```
**Step 2:** Configure the JWT authentication middleware **_‘Startup.cs’_**
```
using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.IdentityModel.Tokens;
using System;
using System.Text;
public void ConfigureServices(IServiceCollection services)
{
// Other configurations within the code...
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = "yourIssuer",
ValidAudience = "yourAudience",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("yourSecretKey"))
};
});
// Other services...
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
// Middleware configurations...
app.UseAuthentication();
app.UseAuthorization();
// Other configurations within the code...
}
```
**Step 3:** Generate the JWT tokens after the successful authentication and then include them within the responses.
## Explore The Role Based Authorization in .NET Core
The [Role Based Authorization in .NET Core](https://positiwise.com/blog/role-based-authorization-in-net-core) grants access to the resources based on the predefined roles that are already assigned to the users. Let us now look at the steps to implement the same:
**Step 1:** Define the roles and assign them to the users.
**Step 2:** Create the authorization policies that are based on the roles in **_‘Startup.cs’_**
```
public void ConfigureServices(IServiceCollection services)
{
// Other configurations...
services.AddAuthorization(options =>
{
options.AddPolicy("AdminOnly", policy =>
policy.RequireRole("Admin"));
});
// Other services...
}
```
**Step 3:** Apply the authorization policies to controllers or the actions using the **_‘[Authorize]’_** attribute.
```
[Authorize(Policy = "AdminOnly")]
public IActionResult AdminPanel()
{
// This is the action logic for admin panel
}
```
## Creating Custom Authentication Schemes in .NET Core
Oftentimes, inbuilt .NET Authentication mechanisms may not suffice for the specific requirements. Under such cases, your development team can create custom authentication schemes within the .NET Core.
**Step 1:** Implement a Custom Authentication handler by inheriting from the **_‘AuthenticationHandler<T>’_** class.
```
public class CustomAuthenticationHandler: AuthenticationHandler<AuthenticationSchemeOptions>
{
protected override async Task<AuthenticateResult> HandleAuthenticateAsync()
{
// Here is the Authentication logic implemented here
}
}
```
**Step 2:** Configure the authentication middleware to use the custom scheme.
```
public void ConfigureServices(IServiceCollection services)
{
// Other configurations...
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = "CustomScheme";
options.DefaultChallengeScheme = "CustomScheme";
}).AddScheme<AuthenticationSchemeOptions, CustomAuthenticationHandler>("CustomScheme", null);
// Other services...
}
```
**Step 3:** Validating the User Credentials and establishing the identity within the custom authentication handler.
## Authentication and Authorization – Security Best Practices
Though the Authorization and Authentication involves the way to make your business application secure following certain best practices you can get the most out of your Authentication and Authorization in [.NET Core business applications](https://positiwise.com/technologies/dot-net-development).
- **Use ASP.NET Core Identity:** You can use it for handling the authorization and authentication as it provides a strong framework to manage users, passwords, role-based access, and claims-based authorization.
- **Enable Multi-Factor Authorization (MFA):** It is crucial to add an extra layer of security enabling the MFA which helps verify the user identity via multiple ways like SMS, email, and authenticator apps.
- **Secure Sensitive Data With HTTPS:** Use HTTPS to encrypt the data within the transit between the client and the server. This prevents the interception and the tampering of sensitive information including the authentication credentials.
- **Use The Storage For Secrets:** Store your sensitive information like the API keys, connection strings, and other secrets. You can use tools like Azure Key Vault or the AWS Secrets Manager and manage the access securely.
- **Update and Patch Dependencies:** Make sure that your .NET Core libraries and dependencies are up to date with the latest security patches. You must review and update all the third-party packages to mitigate the vulnerabilities.
- **Monitor and Log Authentication Events:** Implement the logging and monitoring for the authentication and authorization events. This will help them detect and respond to the authorized access attempts and the security breaches.
- **Prevent Injection Attacks:** Validate and sanitize the user input to protect against SQL injection, cross-site scripting, and other injection attacks. You can use parameterized queries and inbuilt validation frameworks to ensure data integrity.
- **Leverage OAuth2 and OpenID Connect For External Authentication:** To integrate external login providers such as Google, Facebook, or Microsoft, use OAuth2 and OpenID Connect. These protocols present secure methods for user authentication and authorization.
## Conclusion
Implementing robust authentication and authorization mechanisms is crucial for the security and integrity of any web application providing comprehensive and flexible tools to manage authentication and authorization effectively. By leveraging built-in middleware, policies, roles, and custom handlers, you can create secure applications tailored to your specific needs. By following best practices and keeping safety at the forefront of your development process, you can [protect your .NET application](https://positiwise.com/hire-asp-net-developers) and users’ data from unauthorized access and other security threats.

Introduction to Cloud computing: Applications. Benefits, and Risks
Imagine having to go to Zoom headquarters each time you wanted to make a Zoom call. You have to visit Google's California headquarters to utilize Google Chrome at any time. To stream a movie on Netflix, you have to visit the company's headquarters in Scotts Valley each time you want to watch one. The effectiveness and availability of clouds during various activities is the reason we can operate programs, stream video efficiently, and explore more internet possibilities.
Prior to you wondering what kind of cloud is being discussed here, let me clarify.
The cloud that is being discussed is a vast global network of distant (Remote) servers. These servers handle and store data, execute programs, and provide internet-based content and services, such as online mail, office productivity tools, and streaming videos. By storing your files and data on the cloud, you may stop depending on servers and PCs locally. Instead, you may view your data online at any time, from any location, using any device that can connect to the internet. Cloud computing encompasses various specializations, such as cloud security analyst, cloud engineer, cloud architect, cloud administrator, and so forth.
An overview of cloud computing will be provided in this article, along with information on applications, benefits and risks.
The table of contents is as follows:
• What is meant by cloud computing?
• Types of cloud computing?
1. Public cloud
2. Private cloud
3. Hybrid cloud
• Types of cloud services
1. Infrastructure as a service (Iaas)
2. Platform as a service (Paas)

**What is cloud computing ?**
In order to provide quicker innovation, flexible resources, and economies of scale, cloud computing is the transmission of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the internet, or "the cloud."
Anything that also includes providing service delivery over the internet is referred to as cloud computing.
The hardware and software elements needed to properly deploy the architecture of cloud computing are collectively referred to as the cloud infrastructure. On-demand or utility computing are additional terms for **cloud computing**.
The cloud symbol, which is frequently used in flowcharts and diagrams to symbolize the internet, served as the inspiration for the term "
**Types of cloud computing**
Some clouds are different, and only some cloud computing models are appropriate for some situations. A number of models, varieties, and services have been developed to help provide the best option for your requirements.
Before implementing your cloud services, you must choose the kind of cloud deployment or architecture that will be used. Cloud services can be deployed in three different ways: on a hybrid cloud, private cloud, or public cloud.
Private Cloud
Cloud computing capabilities that are exclusively utilized by one company or group are referred to as private clouds. A private cloud may be physically housed in the on-site data center of the business. Additionally, some businesses pay outside service providers to host their private clouds. A private cloud is one where both the services and the infrastructure are kept up to date on a private network. Common private cloud technologies and vendors include VMware and OpenStack.
Public Cloud
Third-party cloud service providers, who offer computing resources like servers and storage over the internet, own and run public clouds. One instance of a public cloud is Microsoft Azure. The cloud provider controls and oversees all of the hardware, software, and other supporting infrastructure in a public cloud. A browser for the web is used to manage your account and access these services.
Hybrid Cloud
Public and private clouds are combined in hybrid clouds, which are connected by a system that permits data and applications to be transferred between them. A hybrid cloud allows your company more deployment options and flexibility by enabling data and apps to migrate between both public and private clouds. It also helps to optimize your current infrastructure, security, and compliance
**Types of Cloud services**
Infrastructure as a service (IaaS), platform as a service (PaaS), serverless, and software as a service (SaaS) are the four main categories into which the majority of cloud computing services can be divided. Reaching your company objectives is made simpler by understanding what they are and how they differ from one another.
IaaS
The lowest tier of cloud computing offerings. Pay-as-you-go cloud providers rent out IT infrastructure, including servers and virtual machines (VMs), storage, networks, and operating systems, under the infrastructure as a service (IaaS) model. IaaS providers allow for instance customization and offer small, medium, big, extra-large, memory- or compute-optimized instances for different workload requirements. For commercial users, the IaaS cloud concept is most similar to a remote data center.
SaaS
Software as a service (SaaS) is the term for a method of delivering software applications over the internet, typically on an as-needed and subscription basis. Software as a Service (SaaS) allows cloud providers to host, manage, and take care of any necessary upkeep for the software program and underlying infrastructure, including security patches and software upgrades. To access the program via the internet, users often utilize a web browser on their phone, tablet, or PC.
PaaS
Cloud computing services that offer an environment for developing, testing, delivering, and managing software applications on demand are referred to as Platform as a Service, or PaaS. With PaaS, developers may more easily and quickly create web and mobile apps without having to worry about configuring or maintaining the servers, storage, networks, and databases that make up the underlying infrastructure. PaaS is used for general software development, and after the software is built, it is hosted by numerous PaaS providers. AWS Elastic Beanstalk, Google App Engine are examples of common PaaS products.
Serverless Computing
Similar to PaaS, serverless computing focuses on creating app functionality rather than continuously maintaining the servers and infrastructure required to make it happen. The cloud provider handles the setup, capacity planning, and server management. Serverless architectures are very scalable and event-driven since they only require resources when a predefined function or trigger is satisfied.
Cloud Computing service Providers
The cloud service market has no shortage of providers. The three largest public CSPs that have established themselves as dominant fixtures in the industry are the following:
• Microsoft Azure
• GCP (Google cloud Provider)
• AWS ( Amazon Web Service)
Other major CSPs include the following:
• Apple
• Citrix
• IBM
• Salesforce
• Alibaba
Examples of Cloud Computing and use cases
Because cloud computing offers so many services and functions, it has developed to meet practically all company demands. Some examples of the variety and power of cloud computing are as follows:
Zoom: Zoom is a cloud-based software platform for audio and video conferences. Users can access the sessions at any time, from any location, by capturing and storing them there. Another well-liked platform for communication and teamwork is Microsoft Teams.
Google Docs: Users get online access to Google Docs . Users are more productive because they can access spreadsheets and presentations stored in the cloud on any device, at any time, from any location.
Email, calendar, Skype, and WhatsApp: Emails, Skype, WhatsApp, calendars, and other cloud-based applications all leverage remote data access to let users examine their data at any time, from any location.
Amazon Lambda: Developers may run code for applications or back-end services without having to provision or manage servers when they use Lambda. The pay-as-you-go model is flexible enough to meet an organization's changing needs for real-time data usage and storage. Other well-known cloud providers like Google Cloud Functions and Azure Functions also enable serverless computing functionalities.
**Applications of Cloud Computing **
Hosting of the workload for production: Businesses are hosting live production workloads on public clouds. Because of this, cloud services and resources must be carefully planned and designed to create an operating environment appropriate for the workload and the required level of resilience.
Huge data analytics: Cloud storage makes it possible to create scalable, adaptable remote data centers that can produce useful information. Big data project-specific services are offered by major cloud providers like Amazon EMR and Google Cloud Dataproc.
IaaS. Infrastructure as a Service (IaaS) enables businesses to host IT infrastructures and obtain scalable access to network, storage, and processing capacity. Businesses can reduce their upfront IT expenditures by using pay-as-you-go subscription arrangements.
Multi clouds:. By evaluating a broad spectrum of cloud services provided by various cloud providers, users can select the best cloud service for a wide range of workloads and requirements.
Storage:. Large volumes of data can be easily accessed and stored remotely. Clients only pay for the storage that they strongly use.
Data backup. Systems for cloud backup are generally easier to use. Users don't have to worry about availability or capacity because the cloud provider takes care of data security.
**Uses of cloud computing**
Cloud computing is probably at work behind the scenes whenever you use an online service for email, document editing, video or TV viewing, music streaming, gaming, or storing photos and other files. For several reasons, a wide range of organizations—from small startups to large multinational enterprises, governmental bodies to non-profits—have adopted cloud computing technologies.
Here are some uses of cloud computing:
Test and create applications:
Scalable cloud infrastructures facilitate easy up scaling and downscaling, hence reducing application development time and cost.
Analyze data
Unify data in the cloud between departments, teams, and geographical locations. Next, use cloud services like artificial intelligence and machine learning to obtain insights that can help you make better decisions.
Data storage, backup, and recovery
By moving your data online to an offsite cloud storage system that is available from any place and on any device, you can protect your data at lower costs and massively.
Playing both audio and video.
Engage your audience with worldwide dissemination of high-definition video and music anytime, anywhere, on any device.
Deliver software
Alternatively referred to as software as a service (SaaS), on-demand software enables you to provide consumers with the most recent software versions and updates—wherever and whenever they need them.
Benefits of Cloud Computing
The following are six typical explanations for benefits of using cloud computing services:
Performance
The largest cloud computing services are powered by a global network of safe data centers that are updated frequently with the newest models of quick and powerful computing gear. Compared to a single corporate datacenter, this provides a number of advantages, including as increased economies of scale and decreased network latency for applications.
Reliability
Cloud computing reduces costs and facilitates data backup, disaster recovery, and business continuity by allowing data to be replicated at several redundant sites on the network of the cloud provider.
Productivity
For physical data centers, a lot of "racking and stacking"—hardware configuration, software patching, and other labor-intensive IT management tasks—is typically required. Thanks to cloud computing, many of these tasks are no longer required, giving IT professionals more time to concentrate on more important business goals.
Speed
With just a few mouse clicks, even massive amounts of processing power can be made available in a matter of minutes, as the majority of cloud computing services are self-service and on-demand. Because of this flexibility, businesses don't have to worry about capacity planning.
Global scale
The elastic scalability of cloud computing services is one of its benefits. This means, in terms of cloud terminology, that the right amount of IT resources—for example, different processing, storage, and bandwidth capacities—are made available at the right time from the right place.
Cost
Businesses that move to the cloud can save money on IT. This is because cloud computing lowers the upfront costs associated with buying hardware and software as well as the setup and upkeep of data centers that are physically located on the premises. These data centers consist of server racks, a constant electrical supply for power and cooling, and IT specialists who manage the infrastructure. It builds up rapidly.
Risks of Cloud Computing
There are numerous similarities between the security threats linked to cloud computing and traditional data center environments. Cyber threats concentrate on taking advantage of and exploiting software flaws in both situations. The possibility of data leaks and cyber attacks is another significant danger. Because public clouds store a lot of data, hackers may find them to be particularly appealing targets. To defend against these attacks, organizations need to have strong network security measures in place, update their security software frequently, and keep an eye out for any unusual activity. However, with cloud computing, a business transfers physical security concerns to another service provider rather than mitigating or absorbing them themselves.
Among the principal dangers are:
1. Loss of Data
As a preventative measure against data loss, backups are essential, and cloud storage is thought to be extremely resilient because it has redundant servers and storage capacity spread over multiple geographical regions. Although cloud storage provides resilience and redundancy, data loss can still occur. Ransom ware attacks are a frequent reason for data loss. Sensitive information may be erased or encrypted by these malicious attempts, rendering its legitimate owner unable to access it. To defend against ransom ware attacks, organizations need to be on guard and put strong security measures in place. Additionally, cloud storage is still susceptible to natural disasters just like any other type of storage. An instance of this occurred in 2019 when a backup generator failed at one of Amazon Web Services data centers, leaving client data unrecoverable. That said, this is rare and AWS reported that less than .5 percent of systems were unrecoverable..
2. Cybercriminals
The Federal Bureau of Investigation's 2022 Internet Crime Report shows that cybercrimes have climbed 69% year over year, suggesting that cybercriminals are on the rise. According to Security Intelligence, modern attackers find it simpler to get past security built on antiquated web and email protocols when they use cloud apps. Denial of service (DoS) assaults are a tactic used by cybercriminals to bar authorized users from accessing servers and services.
3. Compliance Issue
In order to maintain regulatory compliance with standards unique to their business and geographic area, organizations must exercise vigilance. You must be sure that the cloud service provider is meeting your demands for data access and storage related to Personally Identifiable Information (PII) in accordance with GDPR, HIPAA security and privacy regulations, and other business-specific requirements before employing cloud-based services for your data. Furthermore, as cloud services often permit more extensive data access, businesses must ensure that the right access controls and security levels are in place.
4. Insider Threats
Insider threats are a serious danger to cloud computing security. Although we frequently concentrate on outside hackers and cyber attacks, it's crucial to understand that people working for a business can equally unintentionally or purposely jeopardize data security. Data misuse or mismanagement is one of the primary risks linked to insider attacks. Workers who have access to private information may purposefully divulge or steal information, which could have detrimental effects on the company. Employees may also unintentionally result in a security breach by doing things like clicking on a malicious link or falling for a phishing scheme, which gives hackers access to private information.
Cloud computing is a popular option for businesses because to its scalability, affordability, and user-friendliness. However, many companies are concerned about the security risks associated with cloud computing. What is the security of cloud computing? Reputable cloud providers will have robust security mechanisms in place, such as intrusion detection systems, firewalls, and encryption, to protect data stored in the cloud. The vast majority of cloud service providers undergo regular, regular security and maintenance assessments. The level of security may also depend on the organization's internal security protocols. Having read and comprehended the Introduction to cloud computing: alongside its applications, benefits, risk. You might be interested in taking a deeper dive into cloud computing careers and how to begin your career in cloud computing.

1,920,777 | Day 2: Conquering Containers and Kubernetes on the Cloud! | Welcome back, fellow cloud adventurers! Today marks day 2 of our 100-day cloud odyssey, and let me... | 0 | 2024-07-12T08:26:43 | https://dev.to/tutorialhelldev/day-2-conquering-containers-and-kubernetes-on-the-cloud-g6e | 100daysofcode, devops, docker, kubernetes | Welcome back, fellow cloud adventurers! Today marks day 2 of our 100-day cloud odyssey, and let me tell you, it's been a whirlwind of containers and clusters! We delved into the fascinating world of Docker and Kubernetes Engine (GKE) on Google Cloud Platform (GCP).
Docker Deep Dive: Building Our Own Tiny Ships!
Imagine tiny, self-contained ships (containers) carrying your application and all its dependencies. That's the beauty of Docker! We started by building Docker images from scratch, meticulously packing all the necessary components for our application to run smoothly. Think of it like creating a recipe for your containerized app – specific ingredients (code, libraries) ensure it runs consistently across any environment.
But building wasn't enough! We learned to run these containers, bringing our miniature vessels to life. We used commands like docker run to launch them, and even explored debugging techniques to troubleshoot any hiccups. Imagine a tiny mechanic peering into the container to identify the source of the problem!
Docker Hub and Google Artifact Registry: The Container Harbors
Now, imagine a bustling harbor filled with pre-built container ships (images) – that's Docker Hub! We learned how to pull these ready-made containers from the vast Docker Hub repository, saving us precious time from building everything from scratch. But wait, there's more! We also explored Google Artifact Registry, GCP's private harbor for our own custom container images. Pushing our handcrafted images here allows secure storage and easy deployment within GCP projects.
GKE: Orchestrating Our Container Fleet
Okay, so we built individual containers, but what if we have a whole fleet to manage? Enter GKE, the mastermind orchestrator! We learned how to create a GKE cluster, essentially a group of virtual machines working together to manage our containerized applications. It's like having a fleet commander ensuring all the container ships work seamlessly as a unit.
Deploying to the Cluster: Setting Sail!
Now came the exciting part – deploying our applications to the GKE cluster! We used commands and configurations to tell the cluster exactly what to run and where. Imagine giving orders to the fleet commander, and voila! Our applications were up and running within the GKE environment.
Saying Goodbye: Deleting the Cluster (But Not Our Knowledge!)
Finally, we learned how to gracefully delete the GKE cluster when we were done. It's important to clean up resources after use, ensuring cost efficiency and avoiding resource sprawl (imagine a harbor overflowing with unused ships!). However, this doesn't mean our knowledge disappears! We've gained invaluable experience in containerizing and deploying applications to GKE.
Looking Ahead: Day 3 and Beyond!
Day 2 was a jam-packed adventure into Docker and GKE, but this is just the beginning of our 100-day journey. Tomorrow, we'll be exploring new territories, and who knows what exciting cloud concepts await us! Stay tuned and join me as we continue to conquer the cloud together! | tutorialhelldev |
1,920,778 | Create a Spotify Playlist Generator with Arcjet Protection | Introduction Web applications are essential for businesses to deliver digital services,... | 0 | 2024-07-12T08:27:12 | https://dev.to/arindam_1729/create-a-spotify-playlist-generator-with-arcjet-protection-2j93 | node, javascript, beginners, webdev | ## **Introduction**
Web applications are essential for businesses to deliver digital services, and they have become increasingly important in recent years as more and more people access services online.
As web applications become more complex and handle increasingly sensitive data, the need to secure these applications from various threats becomes ever more critical.
In this tutorial, we will build a Spotify playlist generator that can generate personalized music recommendations and secure that with Arcjet, a powerful security framework designed to protect web applications from a wide range of threats.
Let’s dive deep!
## **Project Setup**
### **Create Node.js Project:**
First, we'll create a Simple Node Js Project with the following Command:
```javascript
npm init -y
```
This command will create a package.json file with default settings. The -y flag automatically answers "yes" to all prompts, allowing for a quick setup.
### **Install Dependencies:**
Next, we'll install the required packages by running the following command:
```javascript
npm i express ejs spotify-web-api-node @arcjet/node express-session
```
This will install the following packages:
* **express:** A popular web framework for Node.js
* **ejs:** A simple templating language that lets you generate HTML markup with plain JavaScript
* **spotify-web-api-node:** A wrapper for the Spotify Web API
* **@arcjet/node:** Arcjet SDK for securing Node.js applications
* **dotenv**: Loads environment variables from a .env file
* **express-session:** Middleware for managing sessions in Express applications.
### **Setup Environment Variables:**
Next, we'll create a .env folder to securely store our sensitive information such as API credentials.
**Spotify Setup:**
For Spotify, go to [Spotify Developer Dashboard](https://developer.spotify.com/dashboard) , click on the *Create an app* button, and enter the following information:
* App Name: Spotify Playlist Generator
* App Description: This Application to generate a playlist based on the user’s favourite artist and mood
* Redirect URI: [http://localhost:3000/callback](http://localhost:3000/callback).
Finally, check the *Developer Terms of Service* checkbox and tap on the *Create* button. This will create a new Spotify application.
Once the app is created, we’ll get the client ID and client secret from the Dashboard and add them to our .env file.
```javascript
//.env
SPOTIFY_CLIENT_ID=Your_Spotify_Client_ID
SPOTIFY_CLIENT_SECRET=Your_Spotify_Client_Secret
SPOTIFY_REDIRECT_URI=http://localhost:3000/callback
```
**Arcjet Setup:**
Similarly, you need to set up your Arcjet account to obtain the API key:
1. Create a free account on Arcjet.
2. After logging in, we’ll create a new site. This will generate an API key for your site.
Now, let’s add the Arcjet API key to our .env file:
```javascript
//.env
ARCJET_KEY=Your_Arcjet_Key
```
**Adding Session Secret:**
Finally, we’ll add our session secret to the .env file:
```javascript
//.env
SESSION_SECRET=Your_Session_token
```
### **Create Express Server:**
Now, we'll create an `index.js` file in the root directory and set up a basic express server. See the following code:
```javascript
import express from 'express';
import dotenv from 'dotenv'
dotenv.config();
const app = express();
const port = process.env.PORT || 3000;
//middleware provided by Express to parse incoming JSON requests.
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.get('/', (req, res) => {
res.send('Hello World!');
})
app.listen(port, () => {
console.log(`Server running on port ${port}`);
});
```
Here, We're using the "dotenv" package to access the PORT number from the .env file.
At the top of the project, we're loading environment variables using `dotenv.config()` to make them accessible throughout the file.
### **Run Project:**
Next, we'll add a start script to the `package.json` file to easily run our project.
By using the command node `index.js`, we have to restart your server each time when you make changes to your file. To avoid this we can install `nodemon` using the following command:
```javascript
npm install nodemon
```
Add the following scripts to your Package.json file:
```javascript
"scripts": {
"start": "nodemon index.js"
}
```
The `package.json` file should look like this:
To check whether everything is working or not, let's run the project using the following command:
```javascript
npm run start
```
This will start the Express server. Now if we go to this URL [http://localhost:3000/](http://localhost:3000/) we'll get this:
With this, our basic project setup is done. Next, we’ll add functionalities to it.
## **Project Building**
### **Create the Spotify Client**
To begin, we need to set up the Spotify client, which will let our application to authenticate with Spotify and make API requests.
```javascript
import SpotifyWebApi from 'spotify-web-api-node';
const spotifyApi = new SpotifyWebApi({
clientId: process.env.SPOTIFY_CLIENT_ID,
clientSecret: process.env.SPOTIFY_CLIENT_SECRET,
redirectUri: process.env.SPOTIFY_REDIRECT_URI,
});
```
This initializes a Spotify API client with the necessary credentials and configuration.
**Session Management Middleware:**
To manage user sessions, we will add session management middleware to our application\*\*.\*\*
```javascript
import session from 'express-session';
app.use(session({
secret: process.env.SESSION_SECRET,
resave: false,
saveUninitialized: true,
cookie: { secure: false }
}));
```
This middleware will handle session management, allowing us to store and retrieve session data such as access tokens.
### **Create the Login Route**
With the Spotify client set up, we’ll next create a `/login` route to handle user authentication. This route will redirect users to Spotify's authorization page.
```javascript
app.get('/login', (req, res) => {
const scopes = ['playlist-modify-public', 'playlist-modify-private'];
const authorizeURL = spotifyApi.createAuthorizeURL(scopes);
res.redirect(authorizeURL);
});
```
Here, we’ve defined the scopes required for our application, such as playlist-modify-public and playlist-modify-private, and we’ll use the `createAuthorizeURL` method from the Spotify API client to generate the authorization URL.
We’ll also create a /callback route to handle the callback from Spotify after the user authorizes our application.
```javascript
app.get('/callback', async (req, res) => {
const { code } = req.query;
try {
const data = await spotifyApi.authorizationCodeGrant(code);
req.session.accessToken = data.body['access_token'];
req.session.refreshToken = data.body['refresh_token'];
spotifyApi.setAccessToken(req.session.accessToken);
spotifyApi.setRefreshToken(req.session.refreshToken);
res.redirect('/');
} catch (err) {
console.error('Error during authorization', err);
res.status(500).send('Authorization Error');
}
});
```
This route captures the authorization code from the query parameters, requests an access token and a refresh token from Spotify, and stores the access token in the session. It also sets the access and refresh tokens in the Spotify API client for subsequent requests.
This step is really important as without this step, the user can’t add the generated playlist to their Spotify album.
### **Implement Authentication Middleware**
We'll implement an authentication check to secure our routes and ensure that only authenticated users can access certain functionalities. For that, let’s create a `checkAuth` middleware function
```javascript
const checkAuth = (req, res, next) => {
if (!req.session.accessToken) {
return res.redirect('/');
}
next();
};
```
This function will check if an access token is present. If not, it will redirect the user to the home page. If the access token exists, the middleware will call next() to proceed to the next middleware or route handler.
Additionally, we will create a middleware to refresh the access token if it has expired:
```javascript
const refreshAccessToken = async (req, res, next) => {
if (req.session.accessToken && req.session.refreshToken) {
try {
const data = await spotifyApi.refreshAccessToken();
req.session.accessToken = data.body['access_token'];
spotifyApi.setAccessToken(req.session.accessToken);
next();
} catch (error) {
console.error('Error refreshing access token', error);
res.status(500).send('Internal Server Error');
}
} else {
next();
}
};
```
### **Create the Generate Playlist Route**
Now, we’ll create the `/generate-playlist` route which will create the playlist :
```javascript
app.post('/generate-playlist', checkAuth, async (req, res) => {
const { artistName, mood } = req.body;
try {
const artistData = await spotifyApi.searchArtists(artistName);
if (artistData.body.artists.items.length === 0) {
return res.status(404).send('Artist not found');
}
const artistId = artistData.body.artists.items[0].id;
const recommendations = await spotifyApi.getRecommendations({
seed_artists: [artistId],
seed_genres: [mood],
limit: 12,
});
const tracks = recommendations.body.tracks.map(track => ({
name: track.name,
album: track.album.name,
artists: track.artists.map(artist => artist.name).join(', '),
duration: ${Math.floor(track.duration_ms / 60000)}:${((track.duration_ms % 60000) / 1000).toFixed(0).padStart(2, '0')},
uri: track.uri,
external_url: track.external_urls.spotify,
}));
res.render('playlist', { tracks });
} catch (error) {
console.error('Error generating playlist:', error);
res.status(500).send('Internal Server Error');
}
});
```
Here, we’re taking the artist name and Mood from the user which are used to search for the artist and generate track recommendations. The `searchArtists` method searches for the artist and the `getRecommendations` method generates track recommendations based on the artist and mood.
Additionally, we have structured the generated tracks into a format that can be easily rendered as cards on the frontend.
### **Saving the Playlist:**
Next up we’ll create a `/save-playlist` endpoint to save the generated playlist to the user's Spotify account:
```javascript
app.post('/save-playlist', checkAuth, async (req, res) => {
const { playlistName, trackUris } = req.body;
try {
const userData = await spotifyApi.getMe();
const userId = userData.body.id;
const newPlaylist = await spotifyApi.createPlaylist(userId, {
name: playlistName,
public: false
});
await spotifyApi.addTracksToPlaylist(newPlaylist.body.id, JSON.parse(trackUris));
res.status(200).send(`Playlist '${playlistName}' created successfully!`);
} catch (error) {
console.error('Error creating playlist:', error);
if (error.response) {
console.error('Spotify API response:', error.response);
res.status(error.response.status).send(error.response.data);
} else {
res.status(500).send('Internal Server Error');
}
}
});
```
In this route, we retrieve the user's Spotify ID using the getMe method. We then create a new playlist with the specified name using the `createPlaylist` method. Finally, we add the tracks to the playlist using the `addTracksToPlaylist` method. The track URIs are parsed from the request body and added to the playlist.
## **Adding the User Interface**
Now we’ll integrate EJS templating engine to create a user-friendly interface. EJS allows us to embed JavaScript code within our HTML templates.
For that, we have to set EJS as the view engine in app.js:
```javascript
app.set('view engine', 'ejs');
app.get('/', (req, res) => {
res.render('index', { loggedIn: !!req.session.accessToken });
});
```
In the code above, we set EJS as the view engine using `app.set('view engine', 'ejs')` . When a user visits the home page ('/'), we render the index view and pass a variable `loggedIn` to determine if the user is logged in.
### **Creating the Home Page View**
Next, let's create the `index.ejs` file in the views directory. This file will serve as the home page of our application.
```xml

```
In this view, we use EJS syntax (<% %>) to conditionally render content based on the `loggedIn` variable. If the user is not logged in, a login button is displayed. If the user is logged in, a form is displayed where they can input the artist name and mood to generate a playlist.
### **Creating the Playlist View**
Next, let's create the `playlist.ejs` file in the views directory. This file will display the generated playlist.
```xml

```
In this view, we display the generated playlist in a grid layout. Each track is displayed with its name, artists, album, duration, and a link to listen on Spotify.
We also include a button to create a new playlist, which opens a modal where the user can enter a playlist name and save it to their Spotify account.
## **Securing our Project using Arcjet**
So far, we've built a Spotify Playlist Generator project. But what if it gets hit by spam API requests, SQL injections, or cross-site scripting attacks?
We don't want our server to crash or our application to be compromised! To prevent these issues, we'll add a security layer using Arcjet to protect our application.
### **What is Arcjet?**
Arcjet is a security platform designed to protect web applications from various types of cyber threats, such as **spam API requests**, **SQL injections**, and **cross-site scripting (XSS)** attacks.
It provides a robust security layer that can be easily integrated into web applications to ensure they remain secure and operational even under attack.
**Features**
* [Signup form protection](https://docs.arcjet.com/email-validation/concepts): Arcjet's server-side email verification is configured to block disposable providers and ensure that the domain has a valid MX record.
* [Bot protection](https://docs.arcjet.com/bot-protection/concepts): Protects the route from automated
* [Rate limiting](https://docs.arcjet.com/rate-limiting/concepts): Allows different rate limit configurations based on the user's authentication status. For example, logged-in users can make more requests than anonymous users..
* [Attack protection](https://docs.arcjet.com/shield/concepts): Detects and blocks suspicious behavior, such as SQL injection and cross-site scripting (XSS) attacks.
### **Implementing Arcjet shield to the project**
To implement Arcjet shield in our project, let’s create a new `Arcjet` object with our API key and rules. This should be outside of the request handler.
```javascript
import arcjet, { detectBot, shield, fixedWindow } from '@arcjet/node';
const aj = arcjet({
key: process.env.ARCJET_KEY,
rules: [
shield({
mode: "LIVE",
}),
fixedWindow({
mode: "LIVE",
characteristics: ["ip.src"],
match:"/generate-playlist",
window: "1m",
max: 1,
}),
detectBot({
mode: "LIVE",
block: [
"AUTOMATED",
],
patterns: {
remove: [
"^curl",
],
},
}),
],
});
```
Here, we’ve added multiple layers of security to our application:
* **General Protection:** The shield rule provides a broad layer of protection against common attacks, including the [**OWASP Top 10**](https://owasp.org/www-project-top-ten/).
* **Rate Limiting:** The fixedWindow rule helps prevent abuse by limiting the number of requests to the /generate-playlist endpoint.
* **Bot Detection:** The `detectBot` rule helps identify and block automated bot traffic, ensuring that only legitimate users can access your application.
Now, We’ll create a Middleware function to check if the request is secure. If not, the middleware will throw an error and end the request. Otherwise, it will allow the request to proceed.
```javascript
app.use(async (req, res, next) => {
try {
const decision = await aj.protect(req);
if (decision.isDenied()) {
console.error("Arcjet protection denied", decision);
res.writeHead(403, { "Content-Type": "application/json" });
res.end(JSON.stringify({ error: "Forbidden" }));
} else {
next();
}
} catch (error) {
console.error("Arcjet protection error", error);
res.status(500).send({ error: 'Internal Server Error' });
}
});
```
> Note: To Test Arcjet in the Development server. We need to add the following in our env folder:
>
> ```javascript
> //.env
>
> ARCJET_ENV=development
> ```
>
> This will allow private/internal addresses so that the SDKs work correctly locally.
You can get the whole code here: [https://github.com/Arindam200/spotify-playlist-generator](https://github.com/Arindam200/spotify-playlist-generator)
## **Running it locally:**
To run the project, let’s run the following command in our terminal:
```javascript
npm run dev
```
This will Start Our Server:
Now, Let’s Go to [localhost:3000](http://localhost:3000/) Here, we will get the initial user interface. At this point, we need to log in to our Spotify account to proceed.
After successfully logging in, we’ll get a Form where we can enter our favorite artist and select a mood from the dropdown menu.
After adding them, let’s click on the "Generate Playlist" button. This action will trigger the backend logic to create a playlist based on our inputs.
If we want to reload this page it will throw an error due to rate limits that we have configured in the previous section. The application is configured to allow only one playlist creation request per minute. This means we can only make one request within a one-minute window.
We can also see the error in our terminal:
Now, let’s look at our Arcjet dashboard. Here, we will see all the requests made to our application. This dashboard provides a comprehensive overview of our application's activity.
We can also inspect each request in detail. If a request is denied, the dashboard will provide information on the reason for the denial, helping us to understand and address any issues:
And that’s it! We have successfully set up and Secured our Spotify Playlist Generator project.
> Note: Arcjet reached out to me, inviting me to participate in their beta testing program and share my experience. While they did compensate me for my time, they did not influence the content of this write-up.
## **Conclusion**
In this tutorial, we explored how to build a Spotify Playlist Generator and secure it using Arcjet. By integrating Arcjet's robust protection mechanisms, we ensured that our application is safeguarded against unauthorized access and potential threats.
Now that you’ve learned how to integrate Arcjet for securing your application, you can leverage its powerful features to protect your applications in real-world scenarios.

Its timeless appeal and versatility make it a go-to option for modern construction projects.
But the question lingers: Is structural timber truly a durable construction material?
Understanding Structural Timber
First and foremost, let us understand what structural timber is.
This material encompasses various types of wood specifically engineered and treated for structural purposes. Contrary to conventional lumber used in non-load-bearing applications, structural timber undergoes special processes to enhance its strength, resilience, and longevity.
[Structural timber](www.timbercentral.com.au) is a great choice for building stuff because it's really strong and can handle a lot of weight, making it perfect for houses and big buildings alike. Plus, it's naturally resistant to fire and earthquakes, which is super handy, especially if you live in an area where those things happen a lot.
Strengths and Durability of Structural Timber
Contrary to common misconceptions, structural timber holds impressive load-bearing capabilities. Engineered wood products, such as glue-laminated timber (glulam) and laminated veneer lumber (LVL), further enhance timber's structural performance.
While [timber ](www.timbercentral.com.au)is naturally durable to some extent, its longevity can be compromised by factors such as moisture, insects, and fungal decay. Proper treatment and maintenance are essential to enhance its durability and protect against these threats.
Advancements in timber technology, including pressure treatment and engineered wood products, have significantly improved the lifespan of structural timber in various environments.
Considerations and Mitigation Strategies
Moisture Management: Keeping moisture under control is super important to stop wood from rotting or getting weak. Making sure there's enough air flowing around, using moisture barriers, and checking regularly are all really important things to do.
Fire Resistance: People might think wood burns easily, but if you treat it right and design it well, it can actually be pretty good at resisting fire. Using special coatings and building it in certain ways can make it safer without making it weaker.
Pest Prevention: Keeping an eye out for bugs like termites and other pests is a big deal. Treating the wood before you build and doing regular checks can help stop it from causing damage and keep the structure strong.
Pocket-Friendly Durability: Cost-effectiveness of Structural Timber
In addition to its environmental and structural benefits, [timber](www.timbercentral.com.au) proves to be a cost-effective choice in construction. Its affordability, coupled with ease of handling and quick construction, results in significant cost savings for builders and project owners.
Furthermore, timber's versatility enables efficient construction methods, reducing labour costs and overall project expenses.
In conclusion, structural timber stands as a durable construction material, embodying strength, sustainability, and versatility. While challenges exist in ensuring its long-term durability, advancements in technology and best practices are overcoming these hurdles.

1,920,781 | Some thoughts on Spikes | Hey devs, 🚀 If you are trying to Build Innovative and Technically Challenging Solutions Fast, ... | 0 | 2024-07-12T08:33:21 | https://dev.to/nikoldimit/some-thoughts-on-spikes-494g | spikes, agile | Hey devs,
🚀 If you are trying to Build Innovative and Technically Challenging Solutions Fast, Spikes can be a very effective approach!
While Building Fusion, we embraced the strategy of Spikes to address complex UX and technical challenges efficiently. By focusing on specific problems, testing potential solutions rigorously, and ensuring top-notch UX standards, we were able to integrate solutions seamlessly into our product.
Although this approach led to occasional regressions in existing functionalities, it significantly enhanced productivity and efficiency. For instance, the implementation of "Linked Blocks" within Fusion enabled us to compose API blocks, reducing redundancy in test definitions and cases - but when we initially conceptualised this idea we were not sure how to estimate the work needed for this feature as we had way too many unknowns. We adopted Spikes for this particular challenge and very quickly we were able to identify the work required to build this as a proper feature in Fusion.
While many teams may naturally use this method, explicitly identifying and allocating time for such Spikes, especially in innovative projects, can be highly beneficial.
What are your experiences with using Spikes in your projects? Share examples, along with the upsides and drawbacks you've observed in the comments.
P.S Have you tried fusion yet? If not please do and let me know what you think - we are really going after something completely new in the API tooling/Client space so we are really looking for opinions :)

thanks!

1,920,782 | Unit Tests & Mocking: the Bread and the Butter | Premise Welcome back, folks 🤝 After a while, I finally took the time to start this new... | 28,045 | 2024-07-12T08:36:20 | https://dev.to/ossan/unit-tests-mocking-the-bread-and-the-butter-1hap | go, testing, vscode, webdev |
## Premise
Welcome back, folks 🤝 After a while, I finally took the time to start this new series of blog posts around computer science, programming, and Go. This series will be focused on different things we can deal with when dealing with our daily work.
### How you should read it
Before getting into it, let me share how this blog post (and the upcoming ones) is meant to be read. This blog post targets a specific subject 📍. Therefore, I suggest you read other resources to gain a broader overview. It aims to be your starting point to further dig into the topic. For sure, I'll manage to share resources whenever necessary. Finally, there won't be any GitHub repositories since the code will be pretty focused and not part of a project. Now, you're ready to embark on the journey with unit testing and Go.
## Unit Tests & Mocking
The goal is to be able to write a unit test for a struct that holds a dependency toward another one. Unit testing is a technique in which you test a specific **Unit** by mocking its dependencies. Let's use an example to better depict it. We're going to write a test for the `billing` package. This could be one of the several packages in your codebase. For the sake of the demo, everything has been written to the `billing.go` file (do not do this in production). Within this file, we defined these types:
- The `Invoice` struct model, holding the `CreatedAt` and `Amount` fields
- The `Archiver` interface represents the dependency 💉 our UUT relies on
- The `InvoiceManager` struct is our **Unit Under Test** model
- The `Store` struct implementing the `Archiver` interface
Before showing the code, let me share this drawing to let you understand better the actors:
<p align="center">
<img src="https://dev-to-uploads.s3.amazonaws.com/uploads/articles/day7821kbexs8htuttmz.png" alt="billing package types">
</p>
The complete source code looks like this:
```go
package billing
import (
"errors"
"fmt"
"os"
"time"
"github.com/google/uuid"
)
type Invoice struct {
CreatedAt time.Time
Amount float64
}
type InvoiceManager struct {
Archiver Archiver
}
func (i *InvoiceManager) RecordInvoice(invoice Invoice) (err error) {
id, err := i.Archiver.Archive(invoice)
if err != nil {
return err
}
fmt.Fprintf(os.Stdout, "recorded invoice with id: %s\n", id)
return nil
}
type Archiver interface {
Archive(invoice Invoice) (id string, err error)
}
type Store struct{}
func (s *Store) Archive(invoice Invoice) (id string, err error) {
if invoice.Amount < 0 {
return "", errors.New("amount cannot be less than 0")
}
// logic omitted for brevity
return uuid.NewString(), nil
}
```
### The Unit Under Test 🤠
With the previous code in mind, our task is to write a test for the method `RecordInvoice` based on the `InvoiceManager` receiver type. The function can take two paths:
1. The happy path is when the `i.Archiver.Archive` invocation doesn't return any error
1. The "unhappy" path is when it gives back an error
As good developers, we are asked to write two unit tests. However, we'll write only the happy path test since we would like to focus more on the steps to get there. After all, everybody knows how to write unit tests for this small piece of code.
### First things first: mocking
The `InvoiceManager` struct depends on the `Archiver` interface. Let's see how we can mock it. Here, we have two options: hand-writing it or automatically generating it. We opt for the latter even if the project's size is trivial.
> Be aware that, in real-life projects, this method can save you a consistent amount of time.
#### Mockery tool
We'll take advantage of this tool, which can be downloaded [here](https://vektra.github.io/mockery/latest/). Before proceeding, make sure you have correctly installed it on your machine. To confirm it, you can run this command in your terminal:
```shell
mockery --version
```
In your terminal, navigate to the root folder of your project and run the following command:
```shell
mockery --dir billing/ --name Archiver --filename archiver.go
```
This command specifies three parameters:
- `--dir` is the directory where to look for interfaces to mock: our code is contained within the `billing` folder
- `--name` is the name of the interface to mock: `Archiver` is the identifier for our interface
- `--filename` is the filename for the mock file: we used `archiver.go` to keep the naming convention consistent
When you run the command, you'll notice a new `mock` folder has been created. You'll find the `archiver.go` mock file inside it. By default, the `mockery` tool creates a new folder (and a new package called `mock`) to hold all the mocks.
> If you're not good with this approach, you can override it when running the tool.
Based on my experience, I think the default behavior might be applied in almost all cases. You might also notice that the compiler started to complain. This is due to missing packages in your project. The fix is easy. You should just run the command `go mod tidy` where your `go.mod` file is located. Then, double-check the errors have gone away, and you'll be ready to use the mocks.
### The test code
Let's see how we can exploit the scaffolded mock in our unit tests. By the books, a unit test should have three stages: Arrange, Act, and Assert (aka *AAA* paradigm). We'll cover each of these in the subsequent sections. First, I'm going to show you the code, and then I'll walk you through all the relevant parts of it:
```go
package billing_test
import (
"testing"
"time"
"github.com/ossan-dev/unittestmock/billing"
"github.com/ossan-dev/unittestmock/mocks"
"github.com/stretchr/testify/assert"
)
func TestRecordInvoice(t *testing.T) {
// Arrange
invoice := billing.Invoice{CreatedAt: time.Now(), Amount: 66.50}
store := mocks.NewArchiver(t)
store.On("Archive", invoice).Return("16668b88-34a0-4a25-b1da-6a1875072802", nil).Once()
uut := &billing.InvoiceManager{
Archiver: store,
}
// Act
err := uut.RecordInvoice(invoice)
// Assert
assert.NoError(t, err)
store.AssertExpectations(t)
}
```
#### Arrange 🧱
Here, we've to invoke the function `NewArchiver` from the `mocks` package to get a new instance of our mock. Then, we set it up by using three methods:
1. The `On` method specifies to which invocation this mock has to reply (also with what arguments)
1. The `Return` method specifies which values to return from the mock when invoked
1. The `Once` specifies how many times to return values from this mock
Lastly, we instantiate our **UUT** by passing in the `store` mock as the `Archiver` interface. We can safely proceed.
#### Act 👊
Within this stage, we invoke the method `RecordInvoice` defined on the `uut` variable. No further explanations are needed here.
#### Assert 🤞
In this final stage, we have to check two things:
1. The `uut` variable gives back whatever we expect. In this case, we expect a `nil` error
1. The `store` mock behaves as expected
The second point means that the method `Archive` has been invoked with the expected arguments, the correct number of times, and so on.
## Run Test
Now, we can safely run our test. To run it, we invoke the command:
```shell
go test -v ./billing
```
And that's the outcome on my machine:
```text
=== RUN TestRecordInvoice
recorded invoice with id: 16668b88-34a0-4a25-b1da-6a1875072802
--- PASS: TestRecordInvoice (0.00s)
PASS
ok github.com/ossan-dev/unittestmock/billing 0.004s
```
## That's a Wrap
I hope you found this blog post helpful. As you may imagine, there are several things to cover regarding unit testing, mocking, etc. Any feedback is highly appreciated.

Their duties involve handling various administrative tasks related to patient records and [insurance claims](https://www.invensis.net/ ).
**Medical Coders**
Medical coders translate healthcare services into standardized codes, which are used for billing and record-keeping purposes.
**Their responsibilities include:**
**Reviewing Patient Records:** Coders examine patient records to determine the services and diagnoses provided.
**Assigning Codes:** They use coding systems such as ICD (International Classification of Diseases), CPT (Current Procedural Terminology), and HCPCS (Healthcare Common Procedure Coding System) to assign appropriate codes to each diagnosis and procedure.
**Ensuring Accuracy:** Coders must ensure that the codes accurately reflect the services provided, as errors can lead to claim rejections or denials.
**Staying Updated:** They keep up with changes in coding standards and healthcare regulations to ensure compliance.
**Medical Billers**
Medical billers use the codes assigned by medical coders to prepare and submit insurance claims. Their responsibilities include:
**Preparing Claims:** Billers create and submit claims to insurance companies based on the coded information.
**Following Up:** They track the status of claims and follow up with insurance companies to resolve any issues or discrepancies.
**Handling Payments:** Billers process payments from insurance companies and patients, and update patient accounts accordingly.
**Resolving Disputes:** They address any billing disputes or issues that arise, working with patients and insurance companies to find resolutions.
**Maintaining Records:** Billers keep detailed records of all transactions, payments, and communications related to billing and insurance claims.
**Skills and Knowledge**
Both medical billers and coders need a strong understanding of medical terminology, anatomy, and healthcare regulations. They must also be detail-oriented, have good communication skills, and be proficient in using specialized billing and coding software.
**Importance in Healthcare**
[Medical billers and coders](https://www.invensis.net/services/outsourcing-medical-billing ) ensure that healthcare providers receive proper reimbursement for their services, which is vital for the financial health of medical practices. They also help maintain accurate patient records and ensure compliance with regulations, contributing to the overall efficiency and effectiveness of the healthcare system.

1,920,787 | Laravel Advanced: Top 10 Validation Rules You Didn't Know Existed | Do you know all the validation rules available in Laravel? Think again! Laravel has many ready-to-use... | 27,571 | 2024-07-12T08:42:52 | https://backpackforlaravel.com/articles/tips-and-tricks/laravel-advanced-top-10-validation-rules-you-didn-t-know-existed | laravel, validation | Do you know all the validation rules available in Laravel? Think again! Laravel has many ready-to-use validation rules that can make your code life a whole lot easier. Let’s uncover the top 10 validation rules you probably didn’t know existed.
### 1. **Prohibited**
Want to make sure a field is not present in the input? Use `prohibited`.
```php
'username' => 'prohibited',
```
If `username` is included in the request, validation will fail. Simple and effective, especially for a honeypot!
### 2. **Prohibits**
Need a field to prohibit another field from being present? Check this out.
```php
'password' => 'prohibits:username',
```
If `password` is present, `username` must not be.
### 3. **Required If**
This one’s a lifesaver when you need conditional validation.
```php
'email' => 'required_if:contact_method,email',
```
The `email` field is required only if `contact_method` is `email`.
### 4. **Required Unless**
Opposite of `required_if`. Use it to require a field unless another field has a specific value.
```php
'email' => 'required_unless:contact_method,phone',
```
Here, `email` is required unless `contact_method` is `phone`.
### 5. **Required Without**
This rule is great when you need a field only if another field isn’t present.
```php
'email' => 'required_without:phone',
```
If `phone` isn’t provided, `email` must be.
### 6. **Required Without All**
Step up your game by requiring a field if none of the other specified fields are present.
```php
'email' => 'required_without_all:phone,address',
```
If neither `phone` nor `address` is present, `email` is required.
### 7. **Starts With**
Check if a string starts with a given value.
```php
'username' => 'starts_with:admin,user',
```
The `username` must start with either `admin` or `user`.
### 8. **Ends With**
Similarly, check if a string ends with a specific value.
```php
'username' => 'ends_with:_admin,_user',
```
The `username` must end with either `_admin` or `_user`.
### 9. **In Array**
Confirm a field’s value exists in another **array field**.
```php
'selected_option' => 'in_array:available_options.*',
```
The `selected_option` must be one of the values in the `available_options` array.
### 10. **Different**
Make sure two fields have different values.
```php
'new_password' => 'different:current_password',
```
The `new_password` must be different from the `current_password`.
### Wrapping Up
So there you have it, folks! Ten super handy Laravel validation rules you might not have known about. Using these can save you time and make your code cleaner and more efficient.

Here's how we designed a robust and scaleable system:
Data Retrieval and Processing
BSE Star updates units against orders throughout the market day. Handling this continuous influx of data was our primary challenge.
𝗖𝗵𝗮𝗹𝗹𝗲𝗻𝗴𝗲𝘀
𝗜𝗻𝗰𝗿𝗲𝗮𝘀𝗶𝗻𝗴 𝗢𝗿𝗱𝗲𝗿 𝗩𝗼𝗹𝘂𝗺𝗲: The API returns tens of thousands of orders each run, continuously increasing.
𝗘𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝗗𝗮𝘁𝗮𝗯𝗮𝘀𝗲 𝗖𝗵𝗲𝗰𝗸𝘀: Checking each order against the database was becoming a performance bottleneck.
𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀
𝗡𝗼𝗱𝗲.𝗷𝘀 𝗮𝗻𝗱 𝗖𝗿𝗼𝗻 𝗝𝗼𝗯𝘀: We used Node.js to run scheduled jobs five times a day, fetching and processing data efficiently.
𝗝𝗦𝗢𝗡 𝗙𝗶𝗹𝗲 𝗳𝗼𝗿 𝗢𝗿𝗱𝗲𝗿 𝗧𝗿𝗮𝗰𝗸𝗶𝗻𝗴: We stored processed order numbers in a date-wise JSON file. This allowed us to skip already processed orders and only insert new ones, significantly reducing database load and improving performance.
This approach ensured timely updates and notifications for our clients, enhancing the overall user experience. | mutual_fund_dev |

The table below has two columns, where column B is the number.
We need to repeat the value of column A N times according to the value of column B and concatenate the results into one column.
**Solution**:
Use _**SPL XLL**_ to do this:
```
=spl("=?.conj(~2*[~1])",A1:B2)
```
As shown in the picture below:
**Explanation**:
conj() function concatenates members of a sequence; ~2 represents the 2nd child member of the current member; “integer N* sequence” means copying each member of a sequence N times. | judith677 |

According to “Clean code” book by Uncle Bob, he defined some guidances and rules that developers should follow. This is more imperative for the less experienced developers. With more experience, comes the possibility of breaking some rules or reinventing them with justifications.
**No code comments.**
A good code needs no comment. The variables, methods, and any other component of the code such as attributes should use easily identifiable and descriptive names.
“Code comments are smell, remove them.”
**Dead comments or code should be deleted.**
Any unused piece of code or comments should be deleted. The best place to find them is in the version control systems.
**Incorrect behaviour at boundaries.**
Boundaries should always be unit tested. No behaviour should be assumed.
**Positive conditionals.**
Positive conditionals are easier to read than negative conditionals.

1,920,809 | Managing Kubernetes Clusters like a PRO | Managing multiple Kubernetes clusters can be a complex task, but with the right tools and techniques,... | 0 | 2024-07-12T09:36:26 | https://dev.to/raunaqness/managing-kubernetes-clusters-like-a-pro-10ba | kubernetes, docker, devops, programming | Managing multiple Kubernetes clusters can be a complex task, but with the right tools and techniques, it becomes a seamless part of your workflow.
As a Senior Machine Learning Engineer, I frequently work with various Kubernetes clusters, often needing to view logs or the state of multiple clusters at the same time. In this article, I'm going to show my workflow of how I achieve this using two of my favourite tools - k9s and Warp terminal.
## Tools of the Trade
To keep track of my Kubernetes clusters, I use [k9s](https://k9scli.io/), a powerful terminal-based UI that makes navigating Kubernetes clusters much more manageable.
Paired with [Warp](https://www.warp.dev/), a fast and modern terminal app for MacOS, this combination provides a robust environment for managing multiple clusters.
The visual interface of k9s allows me to monitor cluster resources, check logs, and troubleshoot issues without leaving the terminal.
Let me show you how I set up my cluster, and then you can use this tutorial as a guide to have a similar setup of your own.
### Dev Setup
To connect and interact with a Kubernetes cluster, you need to download and install [kubectl](https://kubernetes.io/docs/tasks/tools/).
kubectl is the command-line tool for interacting with Kubernetes clusters, by communicating with the Kubernetes API server via RESTful API calls, handling all the interactions, communications, and requests between the users.
Once you have kubectl setup installed, you need to have the config of the Kubernetes Cluster stored in your `$HOME/.kube` directory. For example, if you're working with Google Kubernetes Engine, you can run the following command to fetch the details of the specific cluster.
```
gcloud container clusters get-credentials [CLUSTER_NAME] --zone [ZONE] --project [PROJECT_ID]
```
When you run this command, the details of the cluster are stored in a file `$HOME/.kube/config`, the contents of which will look like this :
```
apiVersion: v1
clusters:
- cluster:
certificate-authority-data: <ca-data-here>
server: https://your-k8s-cluster.com
name: <cluster-name>
contexts:
- context:
cluster: <cluster-name>
user: <cluster-name-user>
name: <cluster-name>
current-context: <cluster-name>
kind: Config
preferences: {}
users:
- name: <cluster-name-user>
user:
token: <secret-token-here>
```
This command updates your `kubeconfig` file with the credentials of the specified cluster. However, managing multiple clusters means your `kubeconfig` file can quickly become cluttered.
### Organizing Configurations
To handle multiple cluster configurations efficiently, I create separate configuration files for each cluster. This approach helps me keep things organized and avoids the complexity of managing a single, monolithic `kubeconfig` file. Here’s how you can do it:
1. Fetch Credentials: Use the `gcloud container clusters get-credentials` command to fetch credentials for each cluster.
2. Create Separate Config Files: Save each cluster’s configuration in a separate file, e.g., ~/.kube/config-cluster1, ~/.kube/config-cluster2, etc.
3. Set Up Aliases: Create aliases in your shell configuration file (e.g., `.bashrc` or `.zshrc`) to switch between configurations easily.
Here’s an example of how to set up aliases:
Once you've spent some time setting up cluster configurations, managing and interacting with them daily becomes quite seamless.
Using Warp, I'm also able to split a single terminal window into 2 or more panes to view and interact with multiple clusters at the same time, which is very helpful, for example - when I want to view logs of multiple deployments at the same time.
## Conclusion
Managing multiple Kubernetes clusters doesn’t have to be daunting. By leveraging powerful tools like k9s and Warp terminal, organizing your configurations effectively, and following best practices, you can handle multiple clusters like a pro. Whether you are fetching credentials, monitoring cluster health, or automating tasks, these strategies will help streamline your workflow and ensure smooth operations across all your Kubernetes environments.

1,920,812 | How to improve OCR accuracy ? | my 5-year experience | my experience with OCR technologies I created my 1st image to text converting app on Oct... | 0 | 2024-07-12T09:06:48 | https://abanoubhanna.com/posts/improve-ocr/ | ocr, opensource, android | ## my experience with OCR technologies
I created my 1st image to text converting app on Oct 6th 2018, so it was 5+ years ago. I have been improving, learning, rewriting, iterating, experimenting on OCR technology since then.
I created all of these apps to extract text from images/photos:
- [IMG2TXT: Image To Text OCR](https://play.google.com/store/apps/details?id=com.softwarepharaoh.img2txt) ([opensource](https://github.com/abanoubha/img2txt_app))
- [IMG2TXT OCR App](https://play.google.com/store/apps/details?id=com.softwarepharaoh.img2txt.latin) (discontinued)
- [IMG2TXT Hindi / Indian OCR App](https://play.google.com/store/apps/details?id=com.softwarepharaoh.img2txt.hindi) (will be discontinued after the 1st app supports Hindi/Indian)
- [IMG2TXT : Persian OCR App](https://play.google.com/store/apps/details?id=com.softwarepharaoh.img2txt.persian) (will be discontinued after the 1st app supports Persian)
After all these years, I have a simple thing to say "What is measured, improves". This quote is from "The Effective Executive" book by Peter F. Drucker.
## ideas to improve OCR accuracy
Improving OCR accuracy of extracted text is not a small task. The obvious answer to how to improve text extraction from images is:
- improve "traineddata" models
- use auto correct; for example correct `boxmg` into `boxing`
- use High DPI photo
I used to focus on all of these bullet points and more of them, such as:
- pre-processing images/photo with
- black and white filter
- binarization with adaptive threshold
- increase the DPI of the image artificially to be around 300 dpi
- use the best models from tesseract OCR despite their large size
These ideas led me to improve performance and text accuracy to certain extent. Don't get me wrong! these tips and tricks me my apps run fast enough with good enough accuracy. But I see more accurate apps! for example, Google ML kit produces almost 99% accuracy in text extraction from clear images.
## how to measure OCR accuracy improvement/progress ?
My measurements are not good enough. I need to follow "What is measured, improves" concept. I need to have a set of photos of papers to measure my app's accuracy against. I need a sample of photos that represents the real world use cases. Then I need to refactor and enhance the text extraction accuracy against this sample of images. So, people get the improvements in their daily tasks of typing a paper into digital document.
## specifications of the image sample
I need to collect that image sample with the real world use cases in mind. So I need these images.
- a photo of an old book, the paper is perfectly laid out on an even surface
- a photo of an old book, the paper is warped as the book is open
- a photo of a modern book with clear white background
- a photo of a modern book with some image/illustration between paragraphs
- a photo of an article written in Arabic with some words in English
- a photo of an old yellowish book paper with a cursive font
This is the initial set of image specification of the collected photos. If you have a specific use case, send some photo samples to me on [Twitter (x)](https://x.com/abanoubha) or [LinkedIn](https://linkedin.com/in/abanoub-hanna/).
I hope you enjoyed reading this post as much as I enjoyed writing it. If you know a person who can benefit from this information, send them a link of this post.

1,920,816 | Authorization pitfalls: what does Keycloak cloak? | Author: Valerii Filatov User authorization and registration are important parts of any application,... | 0 | 2024-07-12T09:11:46 | https://dev.to/anogneva/authorization-pitfalls-what-does-keycloak-cloak-cf2 | java, programming, opensource | Author: Valerii Filatov
User authorization and registration are important parts of any application, not only for users but also for security\. What pitfalls does the source code of a popular open\-source identity management solution hide? How do they affect the application?
If you've ever implemented authorization for web apps, you probably know all the frustrating issues that can arise\. I'm no exception, either\.
Once, I implemented the messenger\-based authorization in the frontend part of one project\. It seemed like the world's easiest task but turned out to be the opposite: deadlines were looming, code was tripping over messenger APIs, and people around me were yelling\.
After this case, my colleague showed me a cool tool that would streamline the implementation of authorization in our future projects\. This project was Keycloak, an open\-source Java solution to enable single sign\-on \(SSO\) with identity and access management aimed at modern apps and services\.
As I use the solution myself, I find it interesting to get into the source code and use the PVS\-Studio static analyzer to look for the bugs hidden there\.
## He\-he, classic NullPointerException
> Someone knocked on the door\. The Junior Dev tried to open a door and crashed\. "NullPointerException\!" concluded the Senior Dev\.
Errors related to checking for *null* are encountered in almost every project we've checked before\. So, let's start with this old but gold error\.
**Fragment N1**
```cpp
private void checkRevocationUsingOCSP(X509Certificate[] certs)
throws GeneralSecurityException {
....
if (rs == null) {
if (_ocspFailOpen)
logger.warnf(....);
else
throw new GeneralSecurityException(....);
}
if (rs.getRevocationStatus() ==
OCSPProvider.RevocationStatus.UNKNOWN) { // <=
if (_ocspFailOpen)
logger.warnf(....);
else
throw new GeneralSecurityException(....);
....
}
```
Warning:
[V6008](https://pvs-studio.com/en/docs/warnings/v6008/) Potential null dereference of 'rs'\.
This code snippet has a *null* check, but we need to understand what's going on inside\. If the *\_oscpFailOpen* variable is true, the program won't throw an exception\. It'll only save the log about it and continue execution—it receives a *NullPointerException* in the following *if*, since the *rs* variable has already been used inside *if*\.
It might seem like the program would just throw another exception if there weren't the *NullPointerException*\. But that's not the case because the *\_oscpFailOpen* variable is true, and the program should continue execution\. No fate, it tripped over the *null* pointer and fell into the exception\.
**Fragment N2**
```cpp
public void writeDateAttributeValue(XMLGregorianCalendar attributeValue)
throws ProcessingException {
....
StaxUtil.writeAttribute(
writer,
"xsi",
JBossSAMLURIConstants.XSI_NSURI.get(),
"type",
"xs:" + attributeValue.getXMLSchemaType().getLocalPart() // <=
);
if (attributeValue == null) {
StaxUtil.writeAttribute(
writer,
"xsi",
JBossSAMLURIConstants.XSI_NSURI.get(),
"nil",
"true"
);
....
}
```
Warning*:*
[V6060](https://pvs-studio.com/en/docs/warnings/v6060/) The 'attributeValue' reference was utilized before it was verified against null\.
"Better late than never," this phrase is good enough for many cases, but unfortunately, not for the *null* check\. In the above code snippet, the *attributeValue* object is used before it's checked for existence, which leads to the *NullPointerException*\.
> **Note**\. If you want to check out other examples of such bugs, we've put together [a list](https://pvs-studio.com/en/blog/examples/v6060/) for you\!
## Arguments?
I don't know how it has happened, but Keycloak has errors related to the number of arguments in the format string functions\. It isn't an illustrative statistic—just a fun fact, though\.
**Fragment N3**
```cpp
protected void process() {
....
if (f == null) {
....
} else {
....
if (isListType(f.getType()) && t instanceof ParameterizedType) {
t = ((ParameterizedType) t).getActualTypeArguments()[0];
if (!isBasicType(t) && t instanceof Class) {
....
out.printf(", where value is:\n", ts); // <=
....
}
} else if (isMapType(f.getType()) && t instanceof ParameterizedType) {
....
out.printf(", where value is:\n", ts); // <=
....
}
}
}
```
Warning:
[V6046](https://pvs-studio.com/en/docs/warnings/v6046/) Incorrect format\. A different number of format items is expected\. Arguments not used: 1\.
In the above fragment, when the *printf* function is called, we pass a format string and a value to be substituted into the string\. There's only one problem: there's simply no place in the string to substitute arguments\.
It's pretty interesting that a dev not only copied and pasted both the code fragment from *if* to *else if*, but a dev also copied and pasted the error inside *else if*\.
In the next snippet, we have the opposite case: developers have spared arguments\.
**Fragment N4**
```cpp
public String toString() {
return String.format(
"AuthenticationSessionAuthNoteUpdateEvent
[ authSessionId=%s,
tabId=%s,
clientUUID=%s,
authNotesFragment=%s ]",
authSessionId,
clientUUID,
authNotesFragment); // <=
}
```
Warning:
[V6046](https://pvs-studio.com/en/docs/warnings/v6046/) Incorrect format\. A different number of format items is expected\. Missing arguments: 4\.
Although devs passed the *authSessionId*, *clientUUID* and *authNotesFragment* arguments to the function, the fourth *tabld* argument is a bit missed\.
In this case, the *String\.format* method will throw an *IllegalFormatException*, which can be a nasty surprise\.
## Unclean code
The following PVS\-Studio warnings aren't related to code health errors\. These warnings are more about how high\-quality the code is\. I just pointed out that these aren't firm errors\.
"What's the point of looking at them?" you may think\. First, I believe that code should be clean and neat\. It's not a matter of tastes: clean code is not only about the visual experience but also about code readability\. Imho, it's important for any project, especially Open Source\. Secondly, I'd like to show that the PVS\-Studio static analyzer helps not only fix errors in code but also makes it beautiful and clean\.
### Not enough variables, My Lord\!
For some reason, the following code fragment looks in my mind like an evil plan of someone who has a bad attitude to use variables: "Let's adopt variables and leave them waiting in horror for the garbage collector to gobble them up\.\.\."
**Fragment N5**
```cpp
private void onUserRemoved(RealmModel realm, String userId) {
int num = em.createNamedQuery("deleteClientSessionsByUser")
.setParameter("userId", userId).executeUpdate(); // <=
num = em.createNamedQuery("deleteUserSessionsByUser")
.setParameter("userId", userId).executeUpdate();
}
```
Warning:
[V6021](https://pvs-studio.com/en/docs/warnings/v6021/) The value is assigned to the 'num' variable but is not used\.
From the point of program operation, nothing terrible happens in this code snippet\. But it's still not clear why developers wrote that\.
The *num* variable contains the number of set parameters that the *executeUpdate* method returns\. So, I thought that the method might have had a check for changes\. Even if I rewind in time, I'll only find that calls to the method aren't written to a variable but accept the current state a little later\.
The result is a useless assignment to the variable—just like in the next fragment\.
**Fragment N6**
```cpp
private void verifyCodeVerifier(String codeVerifier, String codeChallenge,
String codeChallengeMethod) throws ClientPolicyException {
....
String codeVerifierEncoded = codeVerifier;
try {
if (codeChallengeMethod != null &&
codeChallengeMethod.equals(OAuth2Constants.PKCE_METHOD_S256)) {
codeVerifierEncoded = generateS256CodeChallenge(codeVerifier);
} else {
codeVerifierEncoded = codeVerifier; // <=
}
} catch (Exception nae) {
....
}
}
```
Warning:
[V6026](https://pvs-studio.com/en/docs/warnings/v6026/) This value is already assigned to the 'codeVerifierEncoded' variable\.
If you look at the code, you can see that before this, the *codeVerifierEncoded* variable has already assigned the same value in the *else* branch\. A developer just did redundant action: and useless, and overcomplicating\.
The next code fragment just amuses me\.
**Fragment N7**
```cpp
private static Type[] extractTypeVariables(Map<String, Type> typeVarMap,
Type[] types){
for (int j = 0; j < types.length; j++){
if (types[j] instanceof TypeVariable){
TypeVariable tv = (TypeVariable) types[j];
types[j] = typeVarMap.get(tv.getName());
} else {
types[j] = types[j]; // <=
}
}
return types;
}
```
Warning:
[V6005](https://pvs-studio.com/en/docs/warnings/v6005/) The variable 'types\[j\]' is assigned to itself\.
It looks just like the previous snippet, but honestly, I'm totally lost on what this code is trying to do\.
At first, I thought we were facing a nested loop here, and the author had just mixed up the variables *i* and *j*\. But eventually I realized that there's only one loop here\.
I also thought the assignment appeared when developers were refactoring the code, which might have been even more complicated before\. In the end, I found that the function was originally created this way \([commit](https://github.com/keycloak/keycloak/commit/72d134748cc200108a41075b209aaabb27d96d09)\)\.
### So sweet copy\-paste
Copy\-paste errors are quite common\. I'm sure you've seen them even in your own code\.
Keycloak has some traces of the copy\-paste use, too\.
**Fragment 8**
```cpp
public class IDFedLSInputResolver implements LSResourceResolver {
....
static {
....
schemaLocations.put("saml-schema-metadata-2.0.xsd",
"schema/saml/v2/saml-schema-metadata-2.0.xsd");
schemaLocations.put("saml-schema-x500-2.0.xsd",
"schema/saml/v2/saml-schema-x500-2.0.xsd");
schemaLocations.put("saml-schema-xacml-2.0.xsd",
"schema/saml/v2/saml-schema-xacml-2.0.xsd");
schemaLocations.put("saml-schema-xacml-2.0.xsd",
"schema/saml/v2/saml-schema-xacml-2.0.xsd"); // <=
schemaLocations.put("saml-schema-authn-context-2.0.xsd",
"schema/saml/v2/saml-schema-authn-context-2.0.xsd");
....
}
....
}
```
Warning*:*
[V6033](https://pvs-studio.com/en/docs/warnings/v6033/) An item with the same key '"saml\-schema\-xacml\-2\.0\.xsd"' has already been added\.
Honestly, even though I knew there was a typo in the source code, I had a hard time finding it right away in the code\.
If you notice, in the *schemaLocations\.put* method calls, the passed arguments are quite similar\. So, I assume that the dev who wrote this code simply copied a string as a template and then just changed values\. The problem is that during copy\-pasting, one line that repeats the previous one has crept into the project\.
Such "typos" can either lead to serious consequences or have no effect at all\. This copy\-pasting example has been in the project since November 21, 2017 \([commit](https://github.com/keycloak/keycloak/commit/a993f6fb7545d24fb9e7b868bfe48ea66bc47543)\), and I don't think it causes any serious problems\.
We're including this error in the article to remind developers to be careful when copying and pasting code fragments and to keep an eye on any changes in code\. Want to read more about it? Here's [the article](https://pvs-studio.com/en/blog/posts/csharp/0708/) about the copy\-paste typos\.
### Unreachable code
The headline gives us a little clue as to what kind of warning awaits us in the following snippet\. I suggest you use your detective skills to spot the flaw yourself\.
**Fragment N9**
```cpp
public void executeOnEvent(ClientPolicyContext context)
throws ClientPolicyException {
switch (context.getEvent()) {
case REGISTER:
case UPDATE:
....
case RESOURCE_OWNER_PASSWORD_CREDENTIALS_REQUEST:
....
executeOnAuthorizationRequest(ropcContext.getParams());
return;
default:
return;
}
}
```
It's not that easy to detect, isn't it? I'm not gloating over you, I just give you a chance to roughly access the situation\. I show it because a small flaw makes it harder for the developer to find the error without examining the rest of the code\. To find out what error is lurking in this code snippet, we need to look at what is cloaked in the *executeOnAuthorizationRequest* method:
```cpp
private void executeOnAuthorizationRequest(MultivaluedMap<String,
String> params) throws ClientPolicyException {
....
throw new ClientPolicyException(....);
}
```
Yes, this method throws an exception\. That is, all the code written after calling this method will be unreachable—the PVS\-Studio analyzer detected it\.
```cpp
public void executeOnEvent(ClientPolicyContext context)
throws ClientPolicyException {
switch (context.getEvent()) {
case REGISTER:
case UPDATE:
....
case RESOURCE_OWNER_PASSWORD_CREDENTIALS_REQUEST:
....
executeOnAuthorizationRequest(ropcContext.getParams());
return; // <=
default:
return;
}
}
```
Warning:
[V6019](https://pvs-studio.com/en/docs/warnings/v6019/) Unreachable code detected\. It is possible that an error is present\.
Even if this flaw is quite small, a similar case could lead to more serious consequences\. I can only note here that a static analyzer will help you avoid such unpleasant things\.
### I dictate CONDITION
Now, let's look at conditional statements and cases when they execute their code\.
**Fragment N10**
```cpp
public boolean validatePassword(AuthenticationFlowContext context,
UserModel user, MultivaluedMap<String, String> inputData,
boolean clearUser) {
....
if (password == null || password.isEmpty()) {
return badPasswordHandler(context, user, clearUser,true);
}
....
if (password != null && !password.isEmpty() && // <=
user.credentialManager()
.isValid(UserCredentialModel.password(password))) {
....
}
}
```
Warning:
[V6007](https://pvs-studio.com/en/docs/warnings/v6007/) Expression 'password \!= null' is always true\.
[V6007](https://pvs-studio.com/en/docs/warnings/v6007/) Expression '\!password\.isEmpty\(\)' is always true\.
Here are two warnings in one line\! What does the analyzer warn us about? The first conditional statement checks that the password is non\-*null* and non\-empty\. If the opposite occurs, the function is no longer executed\. In the line the analyzer highlighted, both of these checks are repeated, so the conditions are always true\.
On the one hand, it's better to check than not to check\. On the other, such duplicates may lead to missing the part of the condition that may be equal to *false*—it can really affect the program operation\.
Let's repeat the exercise\.
**Fragment N11**
```cpp
public KeycloakUriBuilder schemeSpecificPart(String ssp)
throws IllegalArgumentException {
if (ssp == null)
throw new IllegalArgumentException(....);
....
if (ssp != null) // <=
sb.append(ssp);
....
}
```
Warning:
[V6007](https://pvs-studio.com/en/docs/warnings/v6007/) Expression 'ssp \!= null' is always true\.
In general, the case is the same\. If the *ssp* variable is *null*, the program throws an exception\. So, the condition below isn't only true all the time but is also redundant because the corresponding code block will always be executed\.
The condition in the next fragment is also redundant\.
**Fragment N12**
```cpp
protected String changeSessionId(HttpScope session) {
if (!deployment.turnOffChangeSessionIdOnLogin())
return session.getID(); // <=
else return session.getID();
}
```
Warning:
[V6004](https://pvs-studio.com/en/docs/warnings/v6004/) The 'then' statement is equivalent to the 'else' statement\.
In this method, the same code is executed under different seasons, the moon phases, and, most importantly, under different conditions\. So, again, the condition is redundant here\.
Digging into the code, I found the code snippet that is like two drops of water similar to the one above:
```cpp
protected String changeSessionId(HttpSession session) {
if (!deployment.turnOffChangeSessionIdOnLogin())
return ChangeSessionId.changeSessionId(exchange, false);
else return session.getId();
}
```
As you can see, when the condition is executed, the method that changes the session ID is called\.
So, we can make two guesses: either devs just copied the code and changed the condition result, or the first condition still should have updated the session, and this error goes way beyond the "sloppy" code\.
But we mustn't live by redundant conditions alone**\!**
**Fragment N13**
```cpp
static String getParameter(String source, String messageIfNotFound) {
Matcher matcher = PLACEHOLDER_PARAM_PATTERN.matcher(source);
while (matcher.find()) {
return matcher.group(1).replaceAll("'", ""); // <=
}
if (messageIfNotFound != null) {
throw new RuntimeException(messageIfNotFound);
}
return null;
}
```
Warning:
[V6037](https://pvs-studio.com/en/docs/warnings/v6037/) An unconditional 'return' within a loop\.
I have a feeling this *while *was raised by *ifs*\. This code may have some hidden intentions, but the analyzer and I see the same thing here: a loop that always performs one iteration\.
The code author might have wanted a different behavioral outcome\. Even if they don't want, we'll find this code a bit harder to understand than if there is just a conditional operator\.
## String comparison
In the following snippet, a developer suggests everything is so easy\. But it turns out it's not\.
**Fragment N14**
```cpp
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Key key = (Key) o;
if (action != key.action) return false; // <=
....
}
```
Warning:
[V6013](https://pvs-studio.com/en/docs/warnings/v6013/) Strings 'action' and 'key\.action' are compared by reference\. Possibly an equality comparison was intended\.
Comparing strings implies that we compare their contents\. We actually compare object references\. This also applies to arrays and collections, not only strings\. I think it's clear that in certain cases, code operations can lead to unexpected consequences\. Most importantly, it's pretty easy to fix such an error:
```cpp
public boolean equals(Object o) {
....
if (!action.equals(key.action)) return false;
....
}
```
The *equals* method returns a comparison exactly to the contents of two strings\. Victory\!
I'll draw your attention to the fact that the static analyzer has detected the error, which a developer would most likely have missed when reviewing the code\. You can read about this and other reasons for using static analysis in this [article](https://pvs-studio.com/en/blog/posts/0687/)\.
## Double\-checked locking
Double\-checked locking is a parallel design pattern used to reduce the overhead of acquiring a lock\. We first check the lock condition without synchronization\. If it's encountered, the thread tries to acquire the lock\.
If we streamline it, this pattern helps get the lock only when it's actually needed\.
I think you've already guessed that there are bugs in the implementation of this template as I've started talking about it\. Actually, they are\.
**Fragment N15**
```cpp
public class WelcomeResource {
private AtomicBoolean shouldBootstrap;
....
private boolean shouldBootstrap() {
if (shouldBootstrap == null) {
synchronized (this) {
if (shouldBootstrap == null) {
shouldBootstrap = new AtomicBoolean(....);
}
}
}
return shouldBootstrap.get();
}
```
Warning:

The analyzer warns that the *shouldBootstrap* field doesn't have the *volatile* modifier\. What does it affect? In such code, it's likely that different threads use an object until they're fully initialized\.
This fact doesn't seem to be that significant, does it? In the next example, the compiler may change the action order with non\-*volatile* fields\.

```cpp
public class DefaultFreeMarkerProviderFactory

Warning:

Why don't developers fix these code fragments if the bug is so dangerous? The error is not only dangerous but also sneaky\. Everything works as it should most of the time\. There are lots of different reasons why bad behavior can occur, due to, let's say, used JVM or the thread scheduler operations\. So, it can be quite hard to reproduce the error conditions\.
You can read more about such errors and their reasons in the [article](https://pvs-studio.com/en/blog/posts/java/1128/)\.
## Conclusion
At the end of this article, I'd like to point out that I used the analyzer a little out of order\. I just wanted to entertain you and show you the bugs in the project\. However, to fix errors and prevent them, it's better to use the static analyzer regularly while writing code\. You can read more about it [here](https://pvs-studio.com/en/blog/posts/0669/)\.
However, the analyzer helped us spot various errors related both to the program operation and insufficient code cleanliness \(I still think it's important, and you'll hardly change my mind\)\. Errors are not the end of the world if you spot and fix them in time\. Static analysis helps with this\. Try PVS\-Studio and use it to check your project for [free](https://pvs-studio.com/en/pvs-studio/try-free/?utm_source=website&utm_medium=devto&utm_campaign=article&utm_content=1142)\.

#Why did I start?
To be blunt: Because the company I work for, Telstra, is doing a large round of layoffs. In May, 400 people were advised that they were losing their job, some of them I knew. In Mid-July, which is next week at the time of writing this, another 2400.
There's no sugar coating it, layoffs are rough. It's a difficult time for all those involved as for a period of a few months, you never know what your future may hold. As I've now experienced this twice at Telstra, I've come to know that people react differently to the anxiety that these times present. Some people choose to stick their heads down and get on with it, others seek out the company mental health support but unfortunately those two perfectly valid responses never really help me feel better.
As a Consultant, I've always viewed myself more as a Problem Solver rather than an IT Guy and when presented with issues, my brain automatically goes into "fix it" mode… much to the chagrin my wife. So when presented with this issue - the fact that I may be job seeking in a couple months, that's exactly what happened. My brain went into "fix it" mode.
I know its cheesy but this is what came to mind when I was presented with potential job loss.
So in this situation what did it mean to me to get to work?
Given it was early days and the announcement had just been made a few days prior, I outlined a simple list of tasks for me to complete as soon as possible to get an idea of where I stand:
1. Update LinkedIn
2. Update Resume
3. Import the above into my internal company profile
4. Apply for 20 jobs on Seek and see what bites I get.
Step 4 is where I got stuck. I realised I was in an awkward position because my preference was to stay at Telstra and I felt bad about wasting people's time.
##Why is my preference to stay with Telstra, why don't I just leave?
I often get asked this question from family, friends and previous colleagues. To them, it seemed reckless to stay with a company that goes through two layoffs in two years. The reason I stay is because:
1. Telstra gives me reason to stay.
2. I genuinely care about the guys I work with and I love how smart they are.
3. I like my clients as people and respect them as professionals.
4. I use professional development to mitigate the anxiety of possible redundancy and I actually don't mind that.
Point 4 is what made me pivot. If I felt a bit awkward about applying for jobs when I had no intention to leave my existing one, then the next best option was to make myself as an attractive candidate as possible should I be force to.
Which led me to this challenge.
I chose this because I liked the learning philosophy - baptism by fire. I never really got a lot out of doing labs where everything 'just worked' and so a challenge that doesn't hold your hand but at the same time gives you space to be creative, was perfect for me.
And so I updated the focus on my whiteboard and it was time to begin.

Users may seek a US random phone number for Discord for various reasons. Whether you need a random phone number list, random real phone numbers, or a random telephone number generator US, this guide covers it all.

Discord's requirement for phone number verification serves multiple purposes. It helps reduce spam and bot activity, enhances security, and ensures a higher level of accountability among users. However, these benefits can sometimes be a hassle for users who wish to maintain their privacy or manage multiple accounts.
## Understanding the Basics: What is a Random Phone Number?
A random phone number is generated without any specific sequence or personal linkage. These numbers can be used for temporary purposes such as verification codes, avoiding spam, and safeguarding privacy.
A random phone number differs from a regular number as it is not typically assigned to a specific person or permanent device. Instead, these numbers are often provided by third-party services that allocate them temporarily for tasks such as receiving SMS verification codes. This helps users maintain anonymity and protect their personal phone numbers from unwanted exposure.
## Methods to Obtain a US Random Phone Number

1,920,826 | Introduction to NEURAL MACHINE TRANSLATION BY JOINTLY LEARNING TO ALIGN AND TRANSLATE | Introduction Neural machine translation appears more effective than traditional... | 0 | 2024-07-12T09:17:23 | https://dev.to/muhammad_saim_7/introduction-to-neural-machine-translation-by-jointly-learning-to-align-and-translate-4akb | attention, deeplearning, nlp, machinetranslation | ### Introduction
Neural machine translation appears more effective than traditional statistical modeling for translating sentences. This paper introduces the concept of attention in neural machine translation, which is a better approach to translating sentences. Normal neural translators use fixed-length vectors, which do not translate longer sentences correctly. However, this paper uses dynamic-length vectors that better convert longer sentences.
NMT uses an encoder-decoder architecture in which fixed-length vectors were used. The model needs to compress all the information into one single vector, which can be a difficult task for NMT. The performance of NMT decreases as the input length increases.
To address this issue, they introduce an extension of the encoder-decoder which learns to align and translate jointly. Each time the proposed model generates the translation of a word, it searches for the relevant information in the context. The model predicts the target word based on the context vector and all previously generated target words.
## The Encoder-Decoder Framework in Neural Machine Translation
Back then in machine translation statistical techniques are used. Based on specific x the model learn then it predicts y. Equation is argmax(y | X). RNN uses two components first to encode the variable length source sentence to fixed length vector then decode variable length target sentence.
In Encoder-Decoder framework input sentence in sequence of vectors x = (x1,x2, …. , xn) into a vetor c2
ht = f(xt,ht-1)
c = q({h1, …. , hTx})
The decoder is trained to predict the next word yt from all the previous words {yt, … ,yt’-1}. In other words decoder defines the joint probability into condition.
P(y) = ∏p(yt|{y1,….,yt-1},c)
p(yt|{y1,….,yt-1},c) = g(yt-1,st,c)
where g in non linear function the probability of yt and st is hidden state.
### Learning to align and translate
NTM approaches before this paper uses the normal RNN architecture. they introduce bi-direction RNN in which encoder encodes and decoder that emulates through source sentence and decoding the translation.
The model architecture used in paper is following.
P(yi|y1,….,yi-1,X) = g(yi-1,si,ci)
Yi-1 is previous hidden state si is RNN hidden state and ci is current context vector.
### Bi directional RNN
The usual RNN reads the input sequence x from X to Xtx In this paper annotation is not only for single word but it is also for the following words. So bidirectional rnn read the input from (x1, … xn) and calculate the hidden states (h1, … hn) after that RNN f reads the sequence in reverse order (x,…..,x1) compute the hidden state (hn, …. h1).
This model shows good BLEU score for the longer sentences getting score for the RNNsearch-50 is quite optimized.
### Results
There are two kind of models are used RNNsearch and RNNenc. RNNenced have 1000 hidden units each decoder and decoder. The encoder of RNNsearch consist of forward and backward have 1000 units each The results maximizes the condition probability.

These were supposed to be an excellent way to keep ads apart from content, and these showed up while browsing specific websites. However, what was considered to be an effective lead generation tool soon fell out of favor.
While some websites still use these, especially the music or movie download websites, or some news websites, most of these prefer to keep these away. So are these still a useful lead generation tool? The answer is no. Find out why it is so.
## - Very Intrusive
While pop-ups were useful once for the purpose of lead generation and enhancing the on-site experience, these began to be designed and marketed in a very inconvenient way – making it something to be avoided for consumers. Rather than serving as relevant extensions to the content or even being tolerable, pop-up ads became very inconvenient and intrusive for customers.
## - Inviting Ranking Penalties
A new ranking penalty was implemented by Google in 2017. Google essentially puts a penalty on mobile websites using pop-ups such as:
• **Full-screen interstitials –** displayed right after somebody visits a page. This type of pop-up prevents them from viewing any site until its dismissal or closure.
• **Intrusive pop-ups –** covers most of the screen at inopportune moments, such as during the entry time or when visitors are going through your content.
• **Faux pop-ups** which look like interstitial ads, but cannot be closed or dismissed. Instead, visitors are compelled to rack their brains on what they require for ignoring the ads.
As consumer search trends are used by Google to change its rules and algorithm and finds that customers negatively respond to pop-ups being misused in sites, the search engine giant has concluded that these lead to poor [user experience.](https://www.peppersquare.com/ui-ux-design/) Thus, it penalizes websites that show some types of these ads. This is another reason why website pop-ups are not regarded as useful for lead generation.
## Rise of Sticky Banners
Studies have found that small sticky elements, Inline ads and Thinner ads perform better for lead generation than website pop-ups, given that these do not interfere with the overall user experience. Thus, more and more website owners and marketers are using these ad formats to replace website pop-ups.

Maybe you've just got a new job or a promotion, and you start to think that several other people should have gotten the job instead of you, maybe because they are more talented or skillful than you. You should be excited about it, but somehow, you feel that they are going to realize soon that you’re not good enough for the job; this is IMPOSTER SYNDROME, and it sucks. It is all about self-doubt, but it is an unjustified self-doubt, and don't worry, you’re not alone in this; I, as well as many other developers, have had a share of this feeling.
There are several ways to overcome this feeling and leverage it into positive and great outcomes. That is what will be covered in this article. This article will teach you different ways to overcome imposter syndrome as a software developer so that you can start maximizing productivity and achieving your goals.
## Imposter Syndrome and Personal Growth
The software development landscape is dynamic. New technologies emerge constantly, coding languages evolve, and best practices shift. This ever-changing world can be a breeding ground for a pervasive challenge many developers face: imposter syndrome. Developers struggling with this phenomenon often fear being exposed as a "fraud" and experience constant self-doubt. These feelings can significantly hinder personal growth, creating a significant barrier for developers to embrace new challenges, explore different technologies, and ultimately reach their full potential.
One key way imposter syndrome stifles growth is by fostering a fear of new challenges. Developers might feel apprehensive about undertaking unfamiliar projects or stretching their skill sets. The fear of failure or being exposed as incompetent can lead them to cling to familiar ground, hindering their exploration of new technologies, frameworks, and approaches that could accelerate their growth.
Also, developers struggling with imposter syndrome often downplay their accomplishments. They might attribute their successes to luck or external factors rather than their competence. This undermines their confidence and motivation to push themselves further. Imagine a developer who successfully completes a complex project but dismisses it as "beginner's luck."
## The Roots of Imposter Syndrome in Software Development
Several factors contribute to imposter syndrome in software development. Here are the major factors:
### High Expectations
The tech industry thrives on a relentless cycle of innovation and rapid change. This exhilarating atmosphere fosters groundbreaking advancements, pushing the boundaries of what's possible. However, this fast-paced environment also cultivates a culture with high expectations. Developers constantly feel the pressure to perform at an exceptional level, mastering new technologies and paradigms at what often feels like a breakneck pace. The fear of falling behind or not meeting these demanding benchmarks can be all-encompassing, fueling a crippling sense of inadequacy known as imposter syndrome.
### Social Media and Constant Comparison
Newsfeeds and online forums become echo chambers of success stories, showcasing the achievements of coding rockstars and overnight coding prodigies. These carefully curated narratives create a skewed perception of the "norm" in software development. Developers bombarded with these seemingly effortless triumphs can't help but compare their journeys, often feeling like they are lagging far behind. This constant comparison fuels the flames of self-doubt, whispering anxieties that their accomplishments are mere flukes rather than a testament to their skills and dedication. This constant state of self-comparison creates a breeding ground for imposter syndrome, making developers question their abilities and accomplishments regardless of their actual expertise.
### The Myth of the Self-Made Genius
Further complicating the issue is the myth of the "self-made genius" that is often romanticized within the tech ecosystem. Popular culture and media often portray groundbreaking innovations as the work of solitary figures toiling away in basements and garages. This narrative downplays the inherently collaborative nature of software development. Successful projects rely on the combined knowledge, experience, and problem-solving skills of entire teams. However, developers struggling with imposter syndrome might internalize this myth, believing they should intuitively possess all the necessary expertise to excel on their own. This misconception can be incredibly discouraging when faced with challenges. The vast amount of knowledge seemingly required for success feels unobtainable, leading to feelings of inadequacy and hindering their ability to seek help and collaborate effectively within a team environment.
### The Neverending Learning Curve
The field is in a perpetual state of evolution, with new languages, frameworks, and best practices surfacing regularly. While this constant evolution keeps things exciting and intellectually stimulating, it can also be incredibly overwhelming. Developers grappling with imposter syndrome might feel paralyzed by the sheer amount of knowledge they "should" know. This perceived knowledge gap can hinder their motivation to learn and grow. The vast amount of information they feel obligated to master can create a sense of analysis paralysis, preventing them from taking the initiative to explore new technologies and upskill themselves. This fear of inadequacy becomes a self-fulfilling prophecy, reinforcing the negative thoughts and anxieties associated with imposter syndrome.

## How Imposter Syndrome Impacts Developers and Teams
Imposter syndrome doesn't just affect individual developers; it can have a ripple effect on their well-being, professional development, and even team dynamics. The constant feeling of inadequacy and fear of exposure associated with imposter syndrome can take a significant toll on a developer's mental health. Chronic stress, anxiety, and low self-esteem are common consequences. These feelings can not only affect their personal lives but also their professional performance.
One major impact of imposter syndrome is that it leads to stunted professional growth. Developers struggling with imposter syndrome may hesitate to take on challenging projects or opportunities that could propel their careers forward. The fear of failure or being exposed as a "fraud" can lead them to play it safe, sticking to familiar territory and hindering their ability to learn and grow. This can also manifest in a reluctance to seek promotions or leadership roles despite possessing the necessary skills.
Imposter syndrome can also affect team dynamics and collaboration. Developers who constantly doubt their abilities might hesitate to contribute ideas or voice their opinions during meetings. This can lead to a lack of engagement and hinder the team's creativity and problem-solving abilities. Additionally, a developer struggling with imposter syndrome might shy away from seeking help or mentorship from colleagues, missing valuable opportunities for learning and growth.
## Strategies to Overcome Imposter Syndrome
Imposter syndrome doesn't define you. It may feel isolating, but the truth is that it's a surprisingly common experience among developers. The good news is there are strategies to combat these feelings and reclaim your growth path. By implementing these strategies, you can overcome these feelings of inadequacy and unlock your full potential as a developer.
- Challenge the Stigma: Recognize that imposter syndrome is not a reflection of your abilities but a common experience. Understanding this can be a powerful first step in overcoming it.
Embrace the Power of Vulnerability: Honestly discussing your imposter syndrome issues with mentors or peers can be quite beneficial. By talking about your experiences, you can make others feel less alone and also gain insight from their methods for overcoming self-doubt.
- Celebrate Your Wins: Learn to internalize your successes. Don't brush off accomplishments as luck or external factors. Take the time to acknowledge your hard work and skill, building your confidence and motivation to tackle new challenges.
- Perfection is a Myth: Seeking unattainable excellence is a way to breed self-doubt. Recognize that failure is a necessary component of learning. Reframe setbacks as chances to develop and advance your abilities.
- Constructive Criticism as a Tool: Don't view criticism as validating your fears. Instead, use it as a tool for growth. Seek constructive feedback and actively listen to suggestions for improvement. This allows you to learn from your mistakes and become a better developer.
- Community and Mentorship: Engage with online communities of developers and seek out a mentor. A mentor can facilitate that, encourage developers to improve, and make improving easier. 58% of employees, according to [ClearCompany](https://blog.clearcompany.com/5-surprising-employee-development-statistics-you-dont-know), believe that opportunities for professional growth influence how satisfied they are with their jobs.
## Building a Supportive Environment to Combat Imposter Syndrome
Imposter syndrome can thrive in environments that emphasize perfection and downplay challenges. By cultivating a supportive workplace culture, teams can empower developers to overcome self-doubt and reach their full potential. One way to solve this is to create an open dialogue around success and struggle. Encouraging open communication about both successes and failures in a team fosters a sense of shared experience and reduces the stigma associated with mistakes. When developers see their peers openly discussing their struggles, it can validate their own experiences and diminish feelings of isolation.
Another way to build a supportive environment is to encourage developers to experiment, explore new technologies, and embrace challenges. Offer learning resources, workshops, and opportunities for skill development. By emphasizing learning over perfection, the team environment becomes a safe space for growth, and developers are less likely to feel inadequate when encountering unfamiliar territory.

# Using the Vibration API for Haptic Feedback in Web Applications
As a developer, you've probably heard of haptic feedback and the numerous benefits that come with it. Using the Vibration API, you can control the vibration capabilities of compatible devices. That API is a Javascript API that allows you to control the vibration capabilities of a user's device from your web application. It allows you to create feedback experiences by triggering vibrations of various durations and intensities. These vibrations respond to a user's interaction within your web app. It consists of a single method known as `navigator.vibrate()`, which accepts one or two parameters, which are:
- `pattern`: This is an array of numbers representing the vibration pattern. Each number in the array signifies the alternation between the duration of the vibration in milliseconds and the duration of silence between the vibrations. For example, `[100, 200, 300]` would trigger three vibrations: a 100-millisecond vibration, 200 milliseconds of silence, then a 300-millisecond vibration, and so on.
- `options`: The `options` parameter is an optional object that contains properties used to control vibration behavior. Some of these properties include `repeat`, which signifies the number of times the `pattern` should be repeated, and `vibrate`, which allows you to check if a user's device supports vibration.
Using the `navigator.vibrate()` method with your preferred `pattern` and `option`, you can have seamless control over the vibrations on the user's device. You can use the method with a single parameter, which simplifies the process of triggering simple vibrations.
Most modern web browsers, such as [Firefox](https://www.mozilla.org/en-US/firefox/), [Chrome](https://www.google.com/chrome/), and [Safari](https://www.apple.com/safari/), all support the Vibration API. On average, the API is supported on mobile devices like smartphones and tablets, as well as desktops and laptop computers. It's good to note that the support may also vary based on a user's device and operating system. An uncommon device or one with an old operating system might have support issues with the API. For more explanation, you can check out the [vibration API documentation on MDN](https://developer.mozilla.org/en-US/docs/Web/API/Vibration_API).
## Implementing Haptic Feedback with the Vibration API
When integrated using the vibration API, haptic feedback can serve as a powerful tool to boost user experiences in your web apps. It has many benefits, including an increase in user interactions, enhanced notifications, improved accessibility for users with visual or auditory impairments, and better immersion into the gaming experience. With that said, how do you implement haptic feedback with a vibration API into your web apps?
You need to take a few steps to ensure a seamless integration. It usually involves checking for browser support, defining the vibration `pattern`, invoking the vibration `pattern`, and so on. Here's a more detailed step-by-step guide on how to implement haptic feedback with the vibration API:
### Check Browser Support
Before you head on to implementing the haptic feedback, one of the first things you must do involves checking if a user's browser supports the vibration API. You can use feature detection to determine if the `navigator.vibrate()` method is available. Example:
```javascript
if ("vibrate" in navigator) {
// Vibration API is supported
} else {
// Vibration API is not supported
}
```
### Define the Vibration Pattern
You need to determine the vibration `pattern` to be used for different interactions within your web app. The `pattern` can range from a simple vibration to a more complex pattern tailored to specific use cases. For example:
```javascript
// Defining a custom vibration pattern
var customPattern = [100, 200, 300];
```
### Invoke the Vibration API
You must call the `navigator.vibrate()` method with your desired vibration `pattern` and `options`. This is done to trigger haptic feedback. It can be done within event listeners or other relevant parts of the application code. Example:
```javascript
// Trigger a vibration with the custom pattern
navigator.vibrate(customPattern);
```
### Handle Permissions
If applicable, some browsers may require user permission to enable vibration functionality. So, if permission is required, you will need to prompt the user to grant permission before invoking the vibration API. Example:
```javascript
// Check if permission is required
if (navigator.vibrate) {
navigator.vibrate([100]); // Attempt to trigger a vibration
} else {
// Vibration API is not supported or permission denied
// Prompt user to enable vibration functionality
}
```
### Optimize the User Experience
An extra step to follow is to consider the timing and frequency of the haptic feedback. This is to make sure that the user experience is enhanced rather than deteriorated. Use haptic feedback judiciously and sparingly, avoiding excessive or unnecessary vibration that may become annoying. Here's a simple example for button clicks:
```javascript
// Trigger haptic feedback for button clicks
document.getElementById("myButton").addEventListener("click", function () {
navigator.vibrate(50); // Short vibration for button click
});
```
<CTA_Middle_Basics />
## Code Examples for Different Scenarios
Implementing haptic feedback using the vibration API involves writing code to trigger vibrations in response to various interactions. Let's examine some code examples for several scenarios or interactions.
### Notifications
Notifications are an essential aspect of web apps for alerting users to important events or updates. By implementing haptic feedback in notifications, you can ensure that users are alerted to several things they might have missed. Here's a previously mentioned code example that fits perfectly:
```javascript
// Trigger a short vibration for notification
navigator.vibrate(100);
```
### Game Interactions
Haptic feedback enhances immersion in gaming applications by simulating physical sensations corresponding to in-game interaction. By triggering vibrations for game actions such as collisions, character actions, or impacts, you can create a more engaging gaming experience for users. Here's a code example:
```javascript
// Define a custom vibration pattern for a game action
var customPattern = [100, 200, 100, 300, 200];
// Trigger the custom pattern when a game action occurs
function triggerGameAction() {
navigator.vibrate(customPattern);
}
```
### Form Submissions
Providing feedback for form submissions can help reassure users that their actions have been processed. Triggering haptic feedback while submitting a form can help provide users with immediate confirmation and increase the user experience. Here's a code example for form submissions:
```javascript
// Trigger a vibration when the form is submitted
document.getElementById("myForm").addEventListener("submit", function () {
navigator.vibrate(100); // Trigger a short vibration
});
```
## Best Practices for the Vibration API (for Haptic Feedback)
The vibration API can significantly enhance the user experience, but designing effective haptic feedback requires careful consideration of various factors. Why is it so important to design effective feedback? This is because it plays key roles in increasing user benefits, which include:
Usability Enhancements: Haptic feedback should be designed to enhance usability by confirming user interactions. When it is well-designed, interactions become more intuitive and responsive.
- Accessibility Improvements: A more thoughtful design can improve accessibility for users with disabilities (especially visual or auditory impairments). By implementing tactile feedback, your web apps can provide additional cues and information that make them more accessible to a wider range of users.
- Engagement and Immersion: Effective haptic feedback can increase a user's immersion and engagement, particularly in gaming and multimedia applications. Simulating physical sensations can enhance realism and make experiences more captivating.
There are also various factors you will need to consider when designing haptic feedback experiences with the vibration API. You must consider the timing, feedback, consistency, and so on. Here's a more detailed explanation of some of these factors:
- Frequency and Intensity: It's important to ensure the frequency and intensity of vibrations provide meaningful feedback that doesn't overwhelm or distract users.
User Preferences: You should consider giving users the option to customize or disable haptic feedback according to their preferences.
- Consistency Across Platforms: Test haptic feedback features across several browsers, devices, and operating systems. This is to ensure that its behavior and performance are consistent. It's important to know the [list of browsers that fully support the Vibration API](https://caniuse.com/vibration) as this will help to work on its consistency.
With the above best practices and factors, you should be able to design an effective haptic feedback experience using the vibration API in your web applications. As technology continues to evolve and users become increasingly accustomed to an interactive and immersive experience, haptic feedback will offer you a valuable opportunity to provide additional layers of engagement.
## Conclusion
In conclusion, integrating haptic feedback using the vibration API represents a significant opportunity for you to elevate the user experience in your web apps. You can create a more intuitive, engaging, and immersive interaction across various contexts by leveraging tactile sensations alongside visual and auditory cues. Throughout this article, we have emphasized the importance of a thoughtful design and consideration of factors such as timing, frequency, user preferences, and consistency. It's important to embrace haptic feedback because, with all the developments going on in the web industry, its roles and benefits are only set to increase and drive more engagement.
