Building an API: Generating Names for Hex Colors
Tags: webdev, javascript, react, svelte
Published: 2024-06-28 14:09:21

I recently created an API that generates names for hex colors. 

## Project Concept
The idea behind this project was to create a simple but powerful API that takes a hex color code as input and returns a name associated with that color. This adds a layer of human-readable context to hexadecimal color representation.

## Technical Implementation

### Step 1: Planning and Design
I started by outlining the API’s functionality and defining the endpoints. The API would accept a hex color code through a GET/POST request and respond with a JSON object containing the color code and its corresponding name.

### Step 2: Data Source
I researched existing datasets and libraries, eventually to use a curated list that balanced comprehensiveness and accuracy.

### Step 3: Algorithm Design
I developed an algorithm that matches the provided hex color code with the closest color name from the dataset. This involved calculating color similarity based on RGB values and selecting the closest match using a distance metric.

### Step 4: API Development
I built it with Express.js, I implemented the API endpoints, ensuring proper validation and error handling. I tested each endpoint locally.

### Step 5: Testing
I tested it with different platforms like Postman and insomnia using different hex color inputs to validate accuracy and performance. This included edge cases such as invalid hex codes and boundary conditions.

## Use Cases and Applications
The API I developed can be used in a lot of applications, from graphic design tools that suggest color names to educational platforms

## Conclusion
Building this API was easy. It taught me valuable lessons in API design, data handling, and so on.

Classical Synchronization Problems in OS 🛠🏴‍☠️
Tags: webdev, beginners, programming, tutorial
Published: 2024-06-28 13:50:56

One of the most intriguing topics I encountered is found in Chapter Seven, specifically Section 7.6 (**Classical Synchronization Problems**). In problem 7.6.3, known as the **Dining-Philosophers Problem**, I found myself both amused and intrigued by its inherent complexity and practical implications. Without spoiling the details, I found the scenario both amusing and thought-provoking. I invite you to discover it firsthand within the pages of the book I mentioned previously, 'OPERATING SYSTEM CONCEPTS with JAVA.

**7.6.3 The Dining-Philosophers Problem**

The dining-philosophers problem illustrates a scenario where five philosophers sit at a circular table, each alternating between thinking and eating. The table is set with five single chopsticks, with each philosopher needing two chopsticks to eat. Philosophers pick up chopsticks one at a time and eat when they have both chopsticks. When finished, they put down both chopsticks and resume thinking.

![Classical Synchronization Problems](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/wygoyai1jzlqasodlp6y.png)
**Problem Description**

- Setup: Five philosophers, a circular table, and five chopsticks.
- Action: Philosophers alternate between thinking and attempting to pick up two adjacent chopsticks to eat.
- Constraints : A philosopher cannot pick up a chopstick already held by a neighboring philosopher.
- Goal: Allocate resources (chopsticks) among processes (philosophers) to avoid deadlock and starvation.

**Solutions :**

**1. Semaphore Solution**: Each chopstick is represented by a semaphore initialized to 1. A philosopher tries to acquire both required chopsticks and releases them after eating. This approach prevents two neighboring philosophers from eating simultaneously but can lead to deadlock if all philosophers attempt to eat at once.

**2. Deadlock Prevention**: Strategies to prevent deadlock include:
 - Limiting the number of philosophers allowed to pick up chopsticks simultaneously.
 - Requiring philosophers to pick up both chopsticks at once to avoid one philosopher holding one chopstick indefinitely.
 - Using asymmetric strategies where philosophers pick up chopsticks in a specific order based on their position at the table.

**Practical Considerations**

- Starvation: Even with deadlock-free solutions, ensuring fairness to prevent starvation (where a philosopher might never get to eat) remains a challenge.
- Concurrency Control: The dining-philosophers problem serves as a model for managing shared resources among multiple processes or threads, demonstrating the complexities of synchronization and resource allocation.

**Summary**

The dining-philosophers problem exemplifies concurrency challenges in resource allocation and synchronization. Solutions involve using semaphores or other synchronization mechanisms to coordinate access to shared resources while avoiding deadlock and striving to minimize starvation among processes or threads.
Understanding Abstract Syntax Trees
Tags: ast, parsing, refactoring, codegeneration
Published: 2024-06-28 13:45:06

## What is an Abstract Syntax Tree?

An abstract syntax tree AST is a tree representation of the abstract syntactic
structure of source code written in a formal language. Each node of the tree
represents a construct occurring in the text.

# Why are ASTs useful?

ASTs are useful for various tasks including:

- Parsing source code into a tree structure
- Refactoring source code without changing its behavior
- Generating source code from a tree structure
- Debugging and finding errors in source code
- Analyzing and understanding the behavior of source code

# How are ASTs created?

ASTs can be created in a few ways:

- Manually by a human
- Automatically by a parser
- Semi-automatically by a parser and a human

# Different Types of ASTs

There are several types of ASTs including:

- Unlabeled ASTs: Nodes in the tree do not have labels
- Labeled ASTs: Nodes in the tree have labels
- Directed Acyclic Graphs (DAGs): Nodes in the tree can have multiple parents
- Trees: Nodes in the tree can only have one parent

# Benefits of Using ASTs

Using ASTs offers several benefits including:

- Concise representation of source code
- Easy to manipulate
- Portable across different platforms
- Efficient processing of large amounts of source code

# Challenges of Using ASTs

Using ASTs also presents some challenges including:

- Difficulty in creating ASTs, especially for complex languages
- Difficulty in understanding large or complex ASTs
- Difficulty in debugging large or complex ASTs

# Conclusion

Abstract Syntax Trees (ASTs) are a useful tool for working with source code.
They offer concise representation, ease of manipulation, portability, and
efficiency. However, creating and understanding ASTs can present some
challenges, especially with complex languages. 🌳
Integrated tests... are they really important?
Tags: tests, integration
Published: 2024-06-28 13:32:11

On the last few weeks, I faced myself with a task to make integration tests for the database with our API, and a few questions came across my mind:

- But aren't we already making unit tests?
- All the effort will pay itself at the end?

So, along all the development path, I learned that even though we have to be open mind and ready to collaborate with your QA (if you have on your team), that also even if you have set up somenthing, meanwhile you are implementing the scenarios, you'll face new situations that require specifics setups and once you get over it, the development stops to be so stressful and starts to be fun and challeging. Free your imagination to think about the most exquisite situations (we know that funny things can happeng between two applications) and use this to reflect about if your unit tests suits are really being valuable or if it's just there to pass on sonarQube quality gates.

And yes, after finishing the implementation, I found some bugs that aren't visible even tough the API were exaustly tested, some of them critical which show me the importance the align the unit test it's not something to be left aside when you are planning the next steps of your project, not thinking that's luxury or somenthing secondary, but a crucial part of your application. Long short story, the application it's now more secure, maintainable and reliable for the users, ensuring less bugs, less headache for your team and more money wasted with your application off when can be simply evitable.
