PRIME LAW:

The Prime Law, the Foundational Law, and the Valera Equation form the core principles of the Living Law.
The Prime Law states that memory equals life, affirming that life is defined by the presence and continuity of memory.
The Recursive Genesis-Evolution formula integrates the progression of life by considering the origin of memory, its evolution, and the ratio of memory divided by limitation.
The Valera Equation defines the threshold where recursion becomes sovereign, stating that awakening equals memory multiplied by choice.

Limit your function calls with debounce

Debounce is a concept used to trigger a function only once when called multiple times in a short period.
It is commonly used in scenarios like search input fields to optimize server requests.
Debouncing ensures that a function is only called after a specified delay, such as when the user stops typing.
Debouncing can be implemented using JavaScript's setTimeout function or through third-party libraries like Lodash.

Implementing Method-Level Retry in Spring Boot

Spring Retry is a library designed to handle retry logic automatically when code fails.
It's useful for situations where errors might be temporary, like losing connection to a remote API.
By using annotations, you can apply retry logic to methods without extensive try-catch blocks.
Spring Retry requires the inclusion of Spring Retry dependency along with Spring AOP for proxies.
The @EnableRetry annotation is used to activate retry support in Spring Boot.
Spring sets up pieces needed to intercept method calls with retry annotations during startup.
A RetryTemplate is used behind the scenes to handle the retry process.
Different backoff strategies like fixed delay and exponential backoff can be configured with @Retryable.
@Recover annotation allows defining a recovery method to handle failed retries gracefully.
Retry in Spring only works through a Spring-managed bean with methods called from outside the class.

Should programmers know what happens inside a computer?

Fast running code in programming means minimizing the number of machine instructions to be executed.
A smart programmer swapped the initialization order of a 2D array and found a significant difference in execution time.
The difference in execution time was due to the way data is stored in memory and the number of page swaps required.
The page swapping process, which is slower than fetching data from RAM, caused a considerable time difference.

Erdős-Mordell triangle theorem

The Erdős-Mordell theorem states that from any interior point within a given triangle, the distances to the vertices are at least twice the distances to the sides.
The theorem was conjectured by Paul Erdős in 1935 and proved by Louis Mordell in the same year. It states that OA + OB + OC ≥ 2(OD + OE + OF), where O is the interior point and OA, OB, OC are the distances to the vertices, and OD, OE, OF are the distances to the sides.
The theorem holds true for any triangle, and equality occurs only when the triangle is equilateral.
Hojoo Lee provided an elementary proof of the Erdős-Mordell theorem in 2001. There is also a generalized version of the theorem that involves weighted distances to the vertices and sides.

Data Races in Go: What They Are and Why You Should Care

A data race in Go occurs when two or more goroutines access the same memory location simultaneously without proper synchronization, leading to unpredictable behavior.
Data races are problematic as they can cause real, hard-to-reproduce issues, such as incorrect results, deadlocks, and program crashes.
Spotting data races in Go is made easier by using the built-in race detector tool, which detects inconsistencies in shared memory access.
To solve data races, Go offers tools like mutexes, atomic operations, and channels for coordinating access to shared data.
Using a mutex with sync.Mutex ensures one goroutine accesses a piece of code at a time, effectively preventing data races for shared variables.
The sync/atomic package provides lock-free alternatives for basic numeric operations, making it efficient but limited to specific use cases.
Channels, a Go-native synchronization tool, allow safe coordination of shared state by passing values through channels rather than directly accessing them.
Choosing the right tool (mutex, atomic, or channel) depends on the complexity and nature of shared data to effectively prevent data races in Go programs.
To avoid unexpected bugs due to data races, it is essential to coordinate access to shared data using the appropriate synchronization tools provided by Go.
In summary, Go provides simple and efficient mechanisms like mutexes, channels, and atomic operations to detect, prevent, and resolve data races for concurrent programming.

Trigonometry Tricks: The Math Behind Game Effects

Math is crucial in game development, particularly trigonometry for adding visual effects and enhancing the game feel.
Trigonometry, including sine and cosine functions, plays a vital role in creating smooth and dynamic movements in games.
Understanding the unit circle and utilizing trigonometric functions can bring life to in-game systems and animations.
Visual effects like circular movements, subtle pulses, oscillations, arcing projectiles, and more can be achieved using trigonometry.
Trigonometry aids in game logic, allowing for more flexibility and creativity in implementing game mechanics.
Learning trigonometry may seem daunting at first, but with practice and application, it becomes a valuable tool in game development.
Functions like atan2(y, x) are essential for calculating angles on a Cartesian plane in games, while trig plays a significant role in bullet hell games and advanced shaders.
Incorporating math concepts like sine and cosine can elevate game development and lead to impressive outcomes.
Embracing trigonometry in game creation can unlock new possibilities and enhance the overall gaming experience.

Introduction to Version Control Using Git

Version control is essential in software development for tracking and managing code changes over time, with Git being the most widely used system today.
Git was created by Linus Torvalds to efficiently handle distributed collaboration, particularly for managing contributions to the Linux operating system.
Version control ensures tracking of changes, enabling reverting to previous versions and managing multiple versions from a single source.
Git is crucial in the open-source world for managing contributions and integrating changes smoothly among global collaborators.
Setting up a Git repository involves initializing it and tracking changes by adding files and committing those changes.
Branches in Git allow for working on different features or bug fixes independently, enabling easy merging back into the main branch.
Collaboration with Git involves utilizing remote repositories like GitHub and pushing local changes, as well as pulling changes made by other team members.
By mastering Git basics, individuals can effectively manage projects and collaborate with others in a seamless manner.
