Sorting algorithm 6: Pigeonhole Sort

Pigeonhole sort is an algorithm that works on integer numbers and is best suited when all the keys are unique.
The steps for performing Pigeonhole Sort involve creating a separate array of pigeonholes, placing the elements from the original array into the pigeonhole array based on their value, and finally copying the elements back to the original array.
An example is provided to explain the process, and the implementation of Pigeonhole Sort in C is also shared.
The time complexity of Pigeonhole Sort is n + 2^k in the worst case scenario.

Python wrappers — cut and keep

Python wrappers are a useful solution for adding logic to functions without altering them.
A wrapper function can be used to measure the time it takes for a function to execute.
Wrappers eliminate the need for repetitive code when applying the same logic to multiple functions.
There are three ready-to-use wrappers available: measure_this, retry_this, and singleton.

New CSS can make your life easier

CSS has introduced a collection of innovative and powerful features.
Container queries allow applying styles to child elements based on the parent container's dimensions.
Style-based container queries enable styling child elements when specific custom properties within the container take on a particular value.
Container units measure dimensions based on the container's size instead of the viewport.
The :has() pseudoselector allows the styling of parent elements based on the presence of specific child elements within them.
View transitions enhance the user experience by animating elements during state changes.
Nesting reduces redundancy in CSS, grouping related styles together.
Scroll-driven animations are tied to scrolling and improve interactivity.
Subgrid ensures consistent alignment across nested grid structures.
CSS continues to evolve at an exciting pace, with even greater design possibilities promised by new HTML elements like . Keep an eye on future developments.

5 React Tricks to Improve Code Quality and Performance

Using ternary operators for conditional rendering results in more predictable and intended behavior, especially when the condition is falsy, which avoids unintended rendering behavior
The useState hook can take a function as its initial value in React, allowing lazy initialization. Using this approach avoids unnecessary computations and improves performance
Lazy loading components is a great way to improve performance, and it is achieved in React with the use of React.lazy() and Suspense components.
By using optional chaining (?.) in JavaScript, you can safely access properties without manually checking for null or undefined
When working with forms in React, it is often better to use useRef instead of useState to avoid re-renders on every input change, making it more performant for large forms.
Applying these five tricks can improve performance, ease maintainability and code readability, leading to better user experiences in React applications

Understanding Goroutines and Channels in Golang with Intuitive Visuals

This article provides an understanding of goroutines, channels, and buffered channels in Go. It includes practical examples and visualizations to help readers understand how to use these tools effectively. Readers are encouraged to run every example and experiment with the code, as well as to build mental models of the concepts covered. The article starts with a simple program that downloads multiple files, which takes six seconds to complete. It then shows how to use goroutines to launch downloads concurrently to reduce the wait time.
Channels in Go are a powerful concurrency primitive used for communication between goroutines. They provide a way for goroutines to safely share data. Channels are blocking by nature, and a send to channel operation ch <- value blocks until some other goroutine receives from the channel. The article explains how to fix the deadlocks that can occur when using channels, such as main not waiting for others issue and how two goroutines can communicate.
The article also covers sync.WaitGroup, a concurrency control mechanism used to wait for a collection of goroutines to finish executing. It shows visualizations of how the WaitGroup maintains an internal counter, and the main goroutine is blocked at Wait() until the counter hits 0. The article then explores buffered channels and their properties, such as sending up to its capacity without blocking the sender. Readers learn when to use buffered channels versus unbuffered channels based on purpose, blocking behavior, performance, and complexity.
Key takeaways from the article include using buffered channels for decoupling sender and receiver timing, improving performance, and when the application can tolerate delays in processing messages when the buffer is full. Use unbuffered channels if there must be immediate synchronization between sender and receiver, when simplicity and immediate hand-off of data is required, and the interaction between sender and receiver must happen instantaneously. With these fundamentals, the article sets the stage for more advanced concepts like concurrency patterns, mutex, and memory synchronization.
