Kirupa·2yBubble Sort: A Detailed Deep-Dive 🛁
Bubble sort is one of the simplest and least efficient sorting algorithms. It sorts a list by repeatedly stepping through and comparing adjacent elements, swapping them if they're in the wrong order. This process is repeated until the list is sorted. Despite its inefficiency (O(n^2) time complexity in average and worst cases), bubble sort is essential for understanding basic sorting concepts and why more efficient algorithms are preferred. The algorithm's primary merit is its simplicity and ease of implementation.
Baeldung·2yData Oriented Programming in Java
This post introduces Data-Oriented Programming (DOP) and contrasts it with Object-Oriented Programming (OOP). It highlights the principles of DOP such as separating data from logic, using immutable data structures, and maintaining data in a valid state. The post includes a practical exercise implementing the game Yahtzee using modern Java features like records, sealed interfaces, and pattern matching. Key distinctions between DOP and OOP are discussed, with examples illustrating the implementation and modeling of data and behavior separately.

Code Maze·2yDifferences Between Record Struct and Record Class in C#
The post highlights the differences between record structs and record classes in C#. Record classes are reference types allocated on the heap, while record structs are value types allocated on the stack. Record classes support inheritance and are immutable by default when using a primary constructor or init-only setters. In contrast, record structs do not support inheritance and require the 'readonly' keyword for immutability. These types are primarily used for lightweight, immutable data structures.
Unity·2yGame programming patterns with Unity 6
An updated edition of the e-book *Level up your code with design patterns and SOLID* for Unity is now available, featuring enhanced content and a sample project based on Unity 6. This guide covers key design patterns including Factory, Object Pooling, Singleton, Command, State, Observer, MVP, MVVM, Strategy, Flyweight, and Dirty Flag, and includes actionable examples for implementing SOLID principles. The sample project can be downloaded from the Unity Asset Store and follows the concepts explained in the guide.
Hacker News·2yj3s.sh
The post expresses frustration with the complex and cluttered output of command-line utilities like `df` and `mount` in the Linux ecosystem. It critiques the disjointed design arising from independently developed programs being merged together, a phenomenon termed 'trainwreck design.' The author discusses the drawbacks of bazaar-style (open community) development where a coherent vision is often lost. They suggest a hybrid model, 'the hive,' with leaders who inspire and guide the project without acting as dictators, aiming to balance community collaboration and coherent design.
Hacker News·2yHow I program in 2024
A programmer reflects on the evolution of their coding practices from 2015 to 2024. They discuss moving away from heavy use of tests and version control, towards more intuitive and context-specific programming strategies. Key insights include the importance of simplicity, avoiding unnecessary abstractions, and the value of periodically rewriting software from scratch to better understand and optimize its function.
