Advent of Code 2024 - Day 14 : Restroom Redoubt
- Day 14 of Advent of Code 2024 focuses on simulating robot movement and calculating the safety factor.
- The simulation involves parsing robot data, calculating new positions using a formula, and counting robots in each quadrant.
- In Part 2, the program detects the 'Christmas tree' pattern by tracking the time when robots cluster into a tight formation.
- The method works by shrinking a bounding box, calculating density, and identifying the time step with the highest density.

How “Smart Labels” Transformed Old-School Java Code
- The research paper 'Converting Java Programs to Use Generic Libraries' presents an algorithm that automates the process of transforming legacy Java code to use generic libraries.
- Before generics, Java programmers used 'raw types' which led to errors and inefficiencies.
- The algorithm identifies types of objects in the code and propagates them into variable and method declarations, ensuring consistency.
- The researchers implemented their algorithm in a tool called Jiggetai, offering automation and many transformative benefits.

Distributed computing made easy
- Distributed computing is two or more servers communicating for a common purpose.
- The computers comprising your distributed system may be on a local network, or they may be worldwide, or some combination of those.
- Most of the time, your distributed system would be on a local network.
- FastCGI, a high-performance binary protocol for communication between servers, clients, and programs of all kinds, may be used in a local network setup.
- Two servers residing on a local network would use the fastest possible means of communication.
- Distributed computing can be used when resources necessary to complete a task aren't all on a single computer, multiple databases need to be accessed, or requests need to be distributed to an application.
- The throughput and latency of distributed computing will vary based on the network(s) setup.
- Secure protocols such as TSL/SSL should be used for communication between servers on the internet.
- A distributed system can be established using physically separate computers or virtual servers such as Virtual Private Servers (VPS) or containers.
- The article provides an example of setting up a simple distributed system using two servers, one acting as a local server and the other as a remote server.

How To Simplify API Request Handling with Page Object Models in Cypress
- When writing Cypress tests, the author found that there was repetition in defining the same request interception in multiple tests, leading to maintenance issues.
- To solve this problem, the author applied the Page Object Model (POM) pattern to centralize request interceptions and waits.
- By moving the interception and wait logic into a POM class, the author simplified test maintenance and reduced code duplication.
- Additionally, the author mentions that using custom commands can be a better approach if the same interception logic applies to multiple pages or components.

LeetCode Challenge: 380. Insert Delete GetRandom O(1) - JavaScript Solution 🚀
- Design a class RandomizedSet that supports insertion, deletion, and random access in O(1) time complexity.
- The implementation uses a hash map for quick lookups and updates and an array for constant-time random access.
- The insert operation adds the value to the end of the array and stores the value's index in the map.
- The remove operation replaces the element to be removed with the last element in the array, updates the last element's index in the map, and removes the last element from the array.
