When to Use type vs interface in TypeScript?

TypeScript offers two main ways to define types: type and interface.
Type is used to define a custom data structure, supporting unions, intersections, and advanced types.
Interface is specifically designed for defining object shapes, supporting inheritance and declaration merging.
Use type for unions, intersections, aliases, and advanced type constructs. Use interface for defining object or class shapes, inheritance, and extending existing structures.

1123. Lowest Common Ancestor of Deepest Leaves

The problem involves finding the lowest common ancestor (LCA) of the deepest leaves in a binary tree.
Post-order traversal is used to efficiently compute the LCA in O(n) time complexity.
The approach computes the maximum depth of left and right subtrees for each node.
If both subtrees have the same depth, the current node becomes the LCA for its subtree.
The solution determines the LCA without explicitly collecting all deepest leaves.
The space complexity is O(h), where h is the height of the tree.
The function dfs performs post-order traversal, processing children before parent nodes.
Depth calculation is done for each node, and the depth is returned along with the LCA for leaf nodes.
Result extraction gives the LCA of the deepest leaves in the entire binary tree.
The approach is implemented using PHP and involves test cases to verify the solution.

Monomorphization The Rust Way

Monomorphization is like making copies of a tool so each copy fits a specific job.
Imagine having a magic hammer that can fix anything, but it takes time to change shape for each job.
Instead of one magic hammer, creating special hammers for each task makes the fixing process faster.
In code, writing one function that works for any type, but the computer creates a specialized version for each type before the program runs.

When I first started solving problems on LeetCode, I jumped in with this innocent hope that…

When first starting to solve problems on LeetCode, the author struggled to keep up with the definitions and success stories of others, leading to a feeling of being lost and purposeless.
After a transformative journey, the author took a break and explored other interests such as astronomy, politics, and history.
Through this journey, the author began to see data structures and algorithms as concepts and tools, rather than just lines of code, and discovered the importance of problem-solving and exploring different efficient solutions.
LeetCode became a sanctuary for the author to enjoy the process of problem-solving and view tech stacks as tools to solve problems with a clear purpose.

4. Unity Particle System: Making Particles React with Collision, Triggers & Lights

Particles in Unity can be manipulated to bounce, detect overlaps, and emit real light for added interaction and realism.
Collision module allows particles to bounce off surfaces or stop on impact, with options to adjust behavior.
Triggers module enables the detection of particle entering or leaving trigger zones, great for triggering game logic.
Lights module adds realism by allowing particles to emit real lights, with options for color, light range, transparency, and more.

Quality Outreach Heads-up - New Null Checks in Inner Class Constructors

The OpenJDK Quality Group is promoting the testing of FOSS projects with OpenJDK builds.
Starting with JDK 25, when javac is targeting release 25 or higher, it will emit null checks for the enclosing instances in inner class constructors.
This behavioral change may lead to new NullPointerExceptions in code that uses core reflection, method handles, or direct bytecode invocation to pass null as enclosing instance.
To prevent the emission of additional null checks, a temporary workaround flag (-XDnullCheckOuterThis=(true|false)) can be used.

How Data Travels the World to Reach Your Screen: A Deep Dive into OSI, TCP/UDP, HTTP, and More

The article delves into how data travels across networks, beginning with an explanation of the OSI model as the foundation for network communication.
An example scenario is provided involving devices connected via a router, illustrating the process of accessing a web page hosted on a server.
The journey of a 'GET' request from a client to a server is detailed, emphasizing the role of the OSI model in facilitating data transfer through layers.
The OSI model's seven layers are explained, highlighting how each layer adds necessary information to the data for efficient transmission.
HTTP, a crucial protocol at the application layer, is explored for adding extra information to data, ensuring secure and structured transfer.
The functions of each OSI layer, including presentation layer's data format and encryption role, and session layer's session establishment, are elaborated.
The transport layer's segmentation of data into segments, and the utilization of TCP or UDP protocols for communication, are discussed.
Network layer's routing of packets, data link layer's framing and MAC address assignment, and physical layer's conversion of data into 1s and 0s are detailed.
The flow of data in reverse order back to the requesting device, the use of HTTP with TCP, and the significance of HTTPS for secure connections are explained.
Detailed explanations of TCP and UDP protocols, their reliability versus speed trade-offs, and their usage in different scenarios are provided.
An in-depth examination of the HTTP protocol, the request-response cycle, HTTP versions, and the evolution to HTTP/2 and HTTP/3 with improved features is presented.

Understanding Stateless vs Stateful Architectures

In a stateful architecture, the server stores session data, such as login status or shopping cart contents, tying the client to a specific server.
To address the issues of stateful architectures, stateless architectures use tokens for authentication instead of storing state on servers.
In stateless architectures, each client request must contain all necessary information for independent processing by the server.
Advantages of stateless architectures include increased scalability, as any server can handle requests, and reduced dependency on specific servers.
On the other hand, stateful architectures maintain client session data between requests, relying on previous interactions.
Functions can also be categorized as stateful or stateless depending on their independence from external variables.
Examples of stateless architectures include REST APIs, where each request carries its state, while common stateful examples include database connections.
In real-world applications, session keys are often used to maintain user sessions, stored in in-memory databases like Redis for efficient access by all servers.
Both stateful and stateless approaches have pros and cons, with stateful architectures requiring additional infrastructure and management for session data.
The decision to use stateful or stateless architecture depends on factors like scalability, flexibility, performance, and maintenance needs of the application.

useDebounce Hook in React

Debouncing in React helps optimize user input by delaying execution until a specified time has passed since the last input, improving performance.
Creating a simple React component without using a custom debounce hook leads to excessive API calls and performance issues.
A custom useDebounce hook is created to delay state updates until the user stops typing, reducing API calls and improving performance.
Advantages of the useDebounce hook include reduced API calls, improved performance, and reusability across components.
Refactoring a component using the useDebounce hook prevents unnecessary API calls, enhances performance, and results in cleaner code.
useDebounce can be used in various scenarios like debouncing input fields in forms, handling window resize events, auto-saving data, and filtering large datasets.
Debouncing input fields in forms prevents unnecessary validations on every keystroke, improving responsiveness.
Handling window resize events using debouncing helps optimize expensive operations and reduces performance issues.
Auto-saving data with debouncing reduces frequent saves as the user types, enhancing user experience.
Filtering large datasets with debouncing minimizes unnecessary re-renders and improves performance in React applications.
