Arrays: Find common element in 3 sorted arrays.

Given 3 sorted arrays, you need to find all the common elements in all the 3 elements.
The problem can be solved by finding the intersection of all the arrays.
Another optimized approach is to use a single loop to find the common elements.
The time complexity for both approaches is O(n1 + n2 + n3), where n1, n2, n3 are the sizes of the 3 arrays.

New CSS Features You Should Know

This article covers modern CSS properties and at-rules that help solve common challenges in web development
The @scope rule defines a boundary within which certain styles apply. This boundary is determined by a selector
The @supports rule checks if a given CSS property or feature is supported by the browser. If the condition evaluates to true, the enclosed styles are applied
The content-visibility property tells the browser to skip the rendering of the element's contents if they're not currently visible in the viewport
The aspect-ratio property ensures the element maintains its proportions even if the container size changes
The @keyframes rule defines a series of style changes that should occur at specified points during an animation
The @starting-style rule helps create smooth and predictable CSS transitions. It defines the initial styles that should be applied to an element before a transition begins.
The offset-position property, used with offset-path, allows for complex, precise animations that go beyond simple linear movements
The text-wrap property adjusts line breaks for improved readability
The white-space-collapse property offers precise control over how whitespace is handled in text, allowing for collapsing, preserving, or other custom behaviors

Mastering Goroutine Pool Management in Go: Boost Performance and Scalability

Goroutine pool management is a crucial aspect of building efficient and scalable concurrent applications in Go.
The core idea is to maintain a fixed number of worker goroutines that can be reused to execute multiple tasks.
Handling panics, waiting for tasks to complete, dynamic sizing, error handling, and metrics collection are key enhancements that developers can make to improve pool management.
An efficient pool can significantly enhance the scalability and efficiency of Go programs.
The specific implementation details may vary depending on the requirements of the application.
A well-implemented goroutine pool can keep resource usage under control, improve performance, and enhance the overall stability of programs.
Developers should profile and benchmark their code to ensure that the goroutine pool is providing the expected performance benefits.
101 Books is an AI-driven publishing company co-founded by author Aarav Joshi.
Users can call pool.Wait() to ensure all submitted tasks have finished executing.
Monitoring the performance of the goroutine pool is crucial in production environments.

5 Powerful Java Frameworks for Serverless Development: Boost Your Cloud-Native Apps

Java serverless development has revolutionized the way we build and deploy applications.
AWS Lambda with Java is a powerful combination for serverless development. The AWS Serverless Application Model (SAM) is particularly useful for deployment and management tasks.
Quarkus is an excellent choice for cloud-native Java applications. Its fast startup times and low memory footprint make it ideal for serverless environments.
Spring Cloud Function provides a uniform programming model across different serverless providers, allowing us to write business logic as plain Java functions.
Micronaut is designed specifically for building microservices and serverless applications. Its ahead-of-time compilation and reduced reflection result in faster startup times and lower memory consumption.
The Fn Project is an open-source, container-native serverless platform that is particularly flexible. It supports multiple languages, including Java, and allows us to run serverless applications on any cloud or on-premises infrastructure.
When developing serverless applications, it's crucial to consider factors like cold start times, memory usage, and integration with cloud services.
These frameworks offer unique features tailored to different serverless environments and development needs.
As we develop more complex serverless applications, we often need to orchestrate multiple functions. AWS Step Functions is a great tool for this when working with AWS Lambda.
Java serverless development offers a rich ecosystem of frameworks and tools.

Java Hibernate OffsetDateTime Mapping

The OffsetDateTime class in Java represents a date-time with a time zone offset from UTC/Greenwich, which can be crucial when working with applications that deal with users in multiple time zones.
When persisting OffsetDateTime in a relational database using Hibernate, it is typically mapped to a TIMESTAMP column.
Hibernate provides a convenient way to store the ZoneOffset associated with an OffsetDateTime using the @TimeZoneColumn annotation.
This decoupled approach offers several advantages.
Let’s explore this through an example.
In this case, the @TimeZoneColumn annotation tells Hibernate to map the ZoneOffset to a separate column.
This ensures that your application can handle time zone conversions and adjustments with minimal overhead, leading to a more robust and globally aware system.
When implementing this solution, it’s important to consider how your application will interact with time zone data and ensure that all relevant fields are appropriately mapped for maximum accuracy.
In summary, mapping OffsetDateTime and its associated ZoneOffset with Hibernate provides a robust solution for working with date-time values across different time zones.
By using the @TimeZoneColumn annotation, you can store both the date-time and its time zone offset in a clean and efficient manner.

How to thrive in an AI powered workplace

Integrating AI sensitively into the workplace while acknowledging the perceptions, negative and positive, around the impact AI may have is going to be an essential skill for the C-suite over the next few years.
The long-term impact of AI will shift focus towards more strategic, analytical, and customer-facing positions as AI takes over routine tasks, requiring adaptation and skill acquisition to stay relevant.
Empathy, Communication, and negotiation will remain essential skills, serving as key differentiators in effectively achieving objectives with both humans and machines.
The need for professionals who understand the ethical implications and regulatory requirements of AI will grow as it becomes more integrated.
AI will take over decision-making tasks across many industries, from financial market trading to human resources, the legal sector and healthcare.
Types of roles in software and testing include Agentic AI Workflow Designer, AI Interaction and Integration Designer, AI Model Validation Engineer, AI Ethics Specialist, Autonomous Testing Engineer, AI-Driven Test Strategist, and more.
AI integration is going to be an evolution as well as a revolution and it has the potential to have more of an impact in a shorter time frame than the industrial revolution of the eighteenth century.
Integrating the human within the AI workforce is going to require, appropriately enough, peculiarly human skills.
AI-driven test engineers, testers using specialized tools, and ethical AI specialists will continue to be in high demand.
The key is to be open to learning new skills and adapting to the changing times.

Arrays: Given an array find the duplicate number

One of the methods to find a duplicate number in an array of integers is by using binary search.
This method involves performing a binary search on the range of possible numbers in the array.
By comparing the count of elements greater than the midpoint of the range, the search space is narrowed down to find the duplicate number.
Another method is by using the fast and slow pointer approach, which is similar to finding a cycle in a linked list.
