Quote of the Week

For some weird reason the Elixir Discord community has a distinct lack of programmer-socks-wearing queer furries, at least compared to Rust, or even most other tech-y Discord servers I’ve seen. It caused some weird cognitive dissonance. Why do I feel vaguely strange hanging out online with all these kind, knowledgeable, friendly and compassionate techbro’s? Then I see a name I recognized from elsewhere and my hindbrain goes “oh thank gods, I know for a fact she’s actually a snow leopard in her free time”. Okay, this nitpick is firmly tongue-in-cheek, but the Rust user-base continues to be a fascinating case study in how many weirdos you can get together in one place when you very explicitly say it’s ok to be a weirdo.

Battle of the Java Web Servers: Which One Reigns Supreme?

The world of web servers is vast and ever-evolving, with new players entering the scene every now and then. For developers seeking the perfect Java web server, it can be quite a daunting task to find the right fit. Fear not, for we have done the research for you and compiled a comparison of six popular Java web servers: Spring HTTP, Micronaut, ActiveJ, Javalin, Vert.x, and Ktor. So, let's dive into this short summary of web java web servers (view the full article)!

Spring HTTP: The Full-Fledged Champion Spring HTTP is not just a web server; it's an entire framework in itself. With support for HTML templating, dependency injection, easy ORM integration, and even GraphQL, Spring HTTP is a powerful choice for building robust web applications. However, it does come with its fair share of disadvantages. It requires the use of Reactive Streams for most threading tasks and struggles to integrate with existing code bases. Additionally, Spring doesn't boast the best performance and consumes more memory compared to other options.

Micronaut: A Microservices Marvel… with Some Drawbacks Micronaut offers an impressive set of features specifically tailored for microservices development. It aims to save developers time by providing a complete microservices framework. However, it falls short in terms of performance, resource usage, and community support when compared to the mighty Spring. Its functionality is also somewhat limited, making it less appealing for more complex projects.

ActiveJ: Lightweight, Modular, and Performance-Oriented For those seeking top-notch performance and a seamless integration with existing code bases, ActiveJ is a strong contender. With its included serialization and ease of support for raw TCP sockets, ActiveJ shines in the performance arena. However, it does have a steeper learning curve due to its new concepts and lacks cross-language compatibility with its serializer.

Javalin: Simple Yet Powerful, with Kotlin in Mind Javalin is an attractive option for developers looking for an easy-to-use web server that integrates well with existing code bases. With its completable futures for threading support and built-in WebSocket server functionality, Javalin is a reasonable choice. However, it lacks some advanced features and feels more targeted towards Kotlin developers, making it a bit less versatile in java heavy environments.

Vert.x: A Complete, Powerful Solution Vert.x offers a feature set similar to Javalin but with a stronger focus on enterprise applications. With its unique threading system, built-in event bus, and extensive support for websockets, TCP sockets, and datagram sockets, Vert.x is a powerful all in one solution for your web server needs, but without the baggage of spring. On top of all of that, Vert.x handles larger code bases well and offers better performance compared with Javalin. However, its Kotlin support is not as extensive, and integrating Vert.x threads with other tools may pose some challenges, but is easily possible.

Ktor: The Kotlin Enthusiast's Choice As the name suggests, Ktor is all about Kotlin. With native KotlinX.Coroutines support and simplicity at its core, Ktor makes it a breeze for Kotlin enthusiasts to build web applications. It even doubles as an HTTP/websocket client for added convenience. However, Ktor falls behind in terms of performance, lacks the versatility of supporting other languages, and may come with additional charges for accessing all its features in certain IDEs.

In conclusion, the battle of Java web servers is a fierce one, with each contender offering its own set of advantages and disadvantages. Spring HTTP stands out as a full-fledged framework with extensive features, while ActiveJ excels in performance and modularity. Javalin and Vert.x provide ease of use and enterprise-level capabilities, with javalin being more Kotlin-centric, and Vert.x being more complete and suitable for larger projects. Micronaut is aimed at microservices but has room for improvement in terms of performance and community support. Lastly, Ktor caters to die-hard Kotlin fans but sacrifices performance and language versatility.

Ultimately, the choice of a web server boils down to your specific needs and preferences. So, strap on your developer hat, analyze your project requirements, and choose the web server that suits you best. Happy coding!

From Idea to Production: Integrating the Token Metrics API in Your App

Building a crypto app—whether for portfolio tracking, market research, or social trading—demands reliable intelligence. With the Token Metrics API, you get a production-ready data layer that seamlessly scales from prototype to enterprise.

Core API Features

AI Reports & Conversational Agent: Generate on-demand, natural-language summaries of token performance. Build chatbots that answer “What’s the Investor Grade on SUI?” with live data.

Performance Analytics: Fetch historical ROI, volatility trajectories, and predictive rankings to power charts, tables, or heatmaps.

RESTful Architecture: Modular endpoints let you query only what you need—minimizing latency and overhead.

SDK Support: Python and Node.js wrappers accelerate integration into backend services or serverless functions.

Step-by-Step Integration

API Key Management: Store your key securely (e.g., environment variable).

SDK Initialization:

from tokenmetrics import TokenMetricsClient

client = TokenMetricsClient(api_key="YOUR_KEY")

Fetch Data (example: top 10 bullish tokens):

const { getTradingSignals } = require("tokenmetrics-sdk");

const signals = await getTradingSignals({ timeframe: "1h", filter: "bullish" });

Render in UI: Visualize grades as colored badges, embed sentiment word clouds, or display ROI charts.

Automated Updates: Use scheduled functions (e.g., AWS Lambda) to refresh data every hour via the API.

Use Case: Mobile Portfolio App

A mobile fintech startup built a React Native app that integrates Token Metrics’ Trader Grades and Market Sentiment endpoints. Users see a consolidated watchlist where each token’s grade is updated in real time. Push notifications alert them if a token moves from neutral to strong-buy. All of this runs on a backend microservice that queries the API every 15 minutes, processes data, and feeds it to the app via GraphQL.

Why SDKs Matter

By leveraging the official SDKs, developers skip the boilerplate of HTTP requests, JSON parsing, and error handling. Instead, they work with intuitive methods and objects. This reduces time-to-market and lowers the risk of integration bugs.

Pricing & Free Tier

Get started with $0 by using the free tier. When you outgrow it, upgrade to the $99 plan—or pay with $TMAI for discounts up to 35%. No hidden costs, just predictable pricing that grows with your usage.

Monitoring and Tracking System Development

Monitoring and tracking systems are essential tools for businesses and organizations to oversee operations, manage resources, and improve efficiency. Whether it's tracking inventory, monitoring network performance, or overseeing employee productivity, effective systems help in making informed decisions. In this post, we will explore the key components of monitoring and tracking system development, popular technologies, and best practices.

What is a Monitoring and Tracking System?

A monitoring and tracking system is software designed to collect, analyze, and display data related to specific processes, assets, or activities. These systems help organizations keep tabs on critical metrics in real-time, identify trends, and respond proactively to issues.

Key Features of Monitoring and Tracking Systems

Data Collection: Gather data from various sources, including sensors, APIs, or user inputs.

Real-Time Monitoring: Provide live data updates and alerts for immediate response.

Reporting and Analytics: Generate reports and visualizations to analyze historical data and trends.

Notifications and Alerts: Notify users of significant events, thresholds, or anomalies.

User Management: Manage user roles, permissions, and access levels.

Common Applications of Monitoring and Tracking Systems

Inventory Management: Track stock levels and manage supply chains.

Network Monitoring: Monitor network performance, bandwidth usage, and downtime.

Employee Productivity: Track work hours, task completion, and performance metrics.

Environmental Monitoring: Collect data on air quality, temperature, and other environmental factors.

Asset Tracking: Monitor the location and status of equipment or vehicles.

Technology Stack Suggestions

Frontend: React.js, Angular, or Vue.js for creating interactive user interfaces.

Backend: Node.js, Django, or Flask for handling server-side logic and data processing.

Database: PostgreSQL, MySQL, or MongoDB for storing data.

APIs: Use RESTful or GraphQL APIs for data exchange between frontend and backend.

Data Visualization: Libraries like Chart.js, D3.js, or Plotly for graphical representation of data.

Sample API Endpoint for Monitoring Data (Node.js Example)

const express = require('express'); const bodyParser = require('body-parser'); const app = express(); app.use(bodyParser.json()); let monitoringData = []; // Mock database for monitoring data // Endpoint to receive monitoring data app.post('/api/data', (req, res) => { const data = req.body; monitoringData.push(data); res.status(201).send({ message: 'Data received successfully!' }); }); // Endpoint to retrieve monitoring data app.get('/api/data', (req, res) => { res.send(monitoringData); }); app.listen(3000, () => { console.log('Server is running on port 3000'); });

Best Practices for Developing Monitoring and Tracking Systems

Define clear objectives and requirements before starting development.

Ensure data accuracy and reliability by implementing validation checks.

Design an intuitive user interface to simplify data interpretation.

Incorporate scalability in your architecture to handle growing amounts of data.

Implement security measures to protect sensitive data and ensure user privacy.

Challenges in Monitoring and Tracking System Development

Handling large volumes of data and ensuring efficient processing.

Integrating with existing systems and ensuring compatibility.

Maintaining data accuracy amidst changes in the environment or processes.

Ensuring real-time performance and responsiveness.

Conclusion

Monitoring and tracking systems are vital for organizations to enhance efficiency, make informed decisions, and respond quickly to issues. By leveraging the right technologies and adhering to best practices, you can build robust systems that provide real-time insights and drive operational excellence. Start small, focus on user needs, and iterate to create impactful solutions in monitoring and tracking.

Unlike RESTful APIs, where the server defines the data structure, GraphQL enables clients to specify the exact data requirements, reducing over-fetching and under-fetching of data.

Key Features of GraphQL:

Declarative Data Fetching: Clients can request specific data, leading to optimized network usage.

Single Endpoint: All data queries are handled through a single endpoint, simplifying the API structure.

Strong Typing: GraphQL schemas define types and relationships, ensuring consistency and clarity.

Introducing Spring GraphQL

Spring GraphQL is a project that integrates GraphQL into the Spring ecosystem. It provides the necessary tools and libraries to build GraphQL APIs using Spring Boot, leveraging the robustness and familiarity of the Spring Framework.

Why Choose Spring GraphQL?

Seamless Integration: Combines the capabilities of Spring Boot with GraphQL, allowing developers to build scalable and maintainable APIs.

Auto-Configuration: Spring Boot's auto-configuration simplifies setup, enabling developers to focus on business logic.

Community Support: Backed by the extensive Spring community, ensuring continuous updates and support.

Setting Up a Spring GraphQL Project

To start building with Spring GraphQL, follow these steps:

1. Create a New Spring Boot Project

Use Spring Initializr to generate a new project:

Project: Maven Project

Language: Java

Spring Boot: Choose the latest stable version

Dependencies:

Spring Web

Spring for GraphQL

Spring Data JPA (if you're interacting with a database)

H2 Database (for in-memory database testing)

Download the project and import it into your preferred IDE.

2. Define the GraphQL Schema

GraphQL schemas define the structure of the data and the queries available. Create a schema file (schema.graphqls) in the src/main/resources/graphql directory:

graphql

Copy code

type Query {

    greeting(name: String! = "Spring"): String!

    project(slug: ID!): Project

}

type Project {

    slug: ID!

    name: String!

    repositoryUrl: String!

    status: ProjectStatus!

}

enum ProjectStatus {

    ACTIVE

    COMMUNITY

    INCUBATING

    ATTIC

    EOL

}

This schema defines a Query type with two fields: greeting and project. The Project type includes details like slug, name, repositoryUrl, and status. The ProjectStatus enum represents the various states a project can be in.

3. Implement Resolvers

Resolvers are responsible for fetching the data corresponding to the queries defined in the schema. In Spring GraphQL, you can use controllers to handle these queries:

java

Copy code

import org.springframework.graphql.data.method.annotation.QueryMapping;

import org.springframework.stereotype.Controller;

@Controller

public class ProjectController {

    @QueryMapping

    public String greeting(String name) {

        return "Hello, " + name + "!";

    }

    @QueryMapping

    public Project project(String slug) {

        // Logic to fetch project details by slug

    }

}

In this example, the greeting method returns a simple greeting message, while the project method fetches project details based on the provided slug.

4. Configure Application Properties

Ensure your application properties are set up correctly, especially if you're connecting to a database:

properties

Copy code

spring.datasource.url=jdbc:h2:mem:testdb

spring.datasource.driverClassName=org.h2.Driver

spring.datasource.username=sa

spring.datasource.password=password

spring.jpa.hibernate.ddl-auto=update

These settings configure an in-memory H2 database for testing purposes.

5. Test Your GraphQL API

With the setup complete, you can test your GraphQL API using tools like GraphiQL or Postman. Send queries to the /graphql endpoint of your application to retrieve data.

Benefits of Using Spring GraphQL

Integrating GraphQL with Spring Boot offers several advantages:

Efficient Data Retrieval: Clients can request only the data they need, reducing unnecessary data transfer.

Simplified API Management: A single endpoint handles all queries, streamlining the API structure.

Strong Typing: Schemas define data types and relationships, minimizing errors and enhancing clarity.

Flexibility: Easily add or deprecate fields without impacting existing clients, facilitating smooth evolution of the API.

Conclusion

Spring GraphQL empowers developers to build flexible and efficient APIs by combining the strengths of GraphQL and the Spring Framework. By following the steps outlined above, you can set up a Spring GraphQL project and start leveraging its benefits in your applications
