How To Run Custom Code on Micronaut Start

When building applications with Micronaut, running custom logic at startup is useful for tasks like initializing resources, validating configurations, or logging startup metrics.
Two common methods for running startup code in Micronaut are by implementing ApplicationEventListener or using @EventListener annotation.
ApplicationEventListener offers precise control over startup events, while @EventListener provides a more concise, annotation-based approach.
Micronaut's lifecycle events enable tasks like initializing resources, pre-loading configuration, registering services, or performing health checks.
Dependencies in the build.gradle file need to be verified and edited if necessary to ensure the project is properly configured for running startup code.
Implementing a StartupListener class using ApplicationEventListener allows for listening to the ApplicationStartupEvent and executing custom startup logic.
An alternate approach is to use an AnnotatedStartupListener class with @EventListener annotation to trigger custom logic during application startup.
By creating the Main Application Class and Configuration File, you can establish the entry point and configure the application settings respectively.
Running the Micronaut application can be done using the Gradle command ./gradlew run, triggering the startup messages to be displayed in the terminal.
Micronaut provides powerful mechanisms for hooking into the application lifecycle, helping maintain a clean, modular, and reactive application architecture.

React View Transitions and Activity API tutorial: Animate an AirBnB clone

The React View Transitions and Activity APIs are experimental features that aim to simplify adding animations to web applications.
The View Transitions API optimizes performance by improving the native API to support the virtual DOM in React.
The Activity API offers a performant way to pre-render or hide UI elements while preserving their state.
To use these APIs, developers need knowledge of JavaScript, experience in building web apps with React, and Node.js v21 installed.
The View Transition API handles transition animations automatically behind the scenes.
Configuring support for React experimental features involves installing the experimental versions of react and react-dom packages.
The tutorial covers animating elements on page transitions, shared element transitions, reordering items in a list, animating from Suspense content, customizing animations, pre-rendering, and visually hiding UI parts.
Developers can customize animations by setting CSS transition properties and using transition classes.
The shared element transition involves adding unique names to components for smooth transitions between pages.
The addTransitionType API allows animations based on transition causes, providing more control over animations triggered in React.

It wasn’t the idea that failed: it was the execution

The year 1995 marked significant advancements in web technologies, including the release of HTML 2.0 and JavaScript, leading to a more interactive online experience.
Development tools like Visual Basic for Windows application development and FrontPage for web design emerged in the early 90s, providing visual interfaces for building applications and websites.
Despite the evolution of visual tools like DreamWeaver and Unreal Engine 1 in 1995, web development leaned towards text-based editors rather than visual tools in the long run.
Visual website tools in the 90s often produced poor HTML markup, leading to accessibility issues for users with assistive technology like screen readers.
The recent introduction of Figma Sites as a visual design tool for the web has faced criticism for not meeting web accessibility standards, highlighting the ongoing challenges in visual web development.
Developers seek control over HTML, CSS, and JavaScript, favoring tools that allow them to generate clean and semantic code, resulting in better website performance.
Nordcraft, an open-source Web Development Engine, stands out by offering developers full control over their HTML markup, CSS, and JavaScript, promoting collaboration between designers and developers.
Nordcraft's approach empowers developers and designers to create websites with complete control over the end result, aiming to avoid the pitfalls of earlier visual web development tools.
In the ever-evolving landscape of web development tools, the focus on providing developers with control and ensuring web accessibility remains crucial for creating successful websites.
The narrative underscores the importance of prioritizing clean code, performance, and accessibility in web development practices to meet the needs of diverse users and adhere to industry standards.

gRPC vs REST: Choosing the best API design approach

When choosing between gRPC and REST for API design, consider factors like performance, protocol, and project requirements.
REST, an architectural style using HTTP methods like GET and POST, is known for its simplicity, human readability, and broad compatibility.
gRPC, Google's high-performance RPC framework, uses HTTP/2 and Protocol Buffers for efficient communication.
gRPC offers advantages like binary serialization, low latency, and bidirectional streaming support over REST.
HTTP/2's features like multiplexing and header compression contribute to gRPC's performance benefits.
REST is suitable for public APIs, browser applications, and simpler CRUD operations, while gRPC excels in microservices and high-performance systems.
Comparison between REST and gRPC includes factors like serialization, network performance, and key advantages of each approach.
Hybrid approaches combining REST and gRPC can be beneficial for systems needing both broad compatibility and performance.
In conclusion, REST is ideal for general compatibility, while gRPC is preferred for performance-intensive applications and microservices environments.
Both API patterns have their strengths, and choosing between gRPC and REST depends on specific project requirements and performance needs.
Consider a hybrid approach, API gateway pattern, or progressive migration based on the operational considerations and client requirements for your project.

SWIFT Strengthens Crypto Oversight as Russia and China Seek Sanction Loopholes

SWIFT is enhancing oversight on crypto transactions to prevent misuse by countries like Russia and China to bypass sanctions. Efforts are being made to detect criminal crypto activity and prevent sanctioned countries from evading Western sanctions.
Russia reportedly uses cryptocurrencies like Bitcoin, Ether, and Tether to circumvent sanctions in its oil trade. Cryptocurrencies enable quick settlements and offer some level of anonymity, raising concerns about money laundering and unregulated trading.
Global crypto regulation is evolving, with SWIFT playing a crucial role in keeping financial flows connected amidst increasing geopolitical tensions. The US has imposed sanctions on crypto exchanges involved in facilitating illicit activities.
While the US and UK tighten crypto regulations, some Asian countries like Japan, South Korea, and Singapore are adopting more lenient approaches towards crypto. However, uncertainties remain regarding these countries becoming alternate routes for sanction-bypassing transactions.

Frequency of papal names

The distribution of names of popes reveals that the top three most common names are John, Benedict, and Gregory, with Leo and Clement tied for fourth place.
There have been instances where some popes are listed twice due to disagreements over who held the papal title, similar to Grover Cleveland and Donald Trump appearing twice on the list of US presidents.
Despite the last pope named John being John XXIII, 21 popes have been named John with the absence of John XX due to a clerical error, and John XVI declared an antipope.
The information on the frequency of papal names was shared by John D. Cook, and a higher resolution PDF is available for further details.
