Python heapq.nlargest vs list.sort

I created a programming language in Go with built-in BDD testing. Looking for feedback and contributors!
https://www.reddit.com/r/programming/comments/1lwpvas/i_created_a_programming_language_in_go_with/
<!-- SC_OFF -->Hey, r/golang (https://www.reddit.com/r/golang)! For the past few months, I've been pouring my free time into a passion project: R2Lang, a new, dynamic programming language written entirely in Go. My main goal was to create a language where testing isn't just a library or an afterthought, but a core, first-class citizen of the syntax. The result is a simple, JavaScript-like language with a native BDD testing framework. TL;DR: I built a JavaScript-like scripting language in Go. Its main feature is a native BDD testing system (TestCase { Given/When/Then }). I'm looking for feedback, ideas, and collaborators to help it grow. GitHub Repo: https://github.com/arturoeanton/go-r2lang ✨ What is R2Lang? It's a dynamic, interpreted language designed for scripting, testing, and building simple web APIs. Think of it as a blend of JavaScript's simplicity and Go's concurrency model. Key Features: 🧪 Built-in BDD Testing: This is the core feature. You can write tests using a clean Given/When/Then structure directly in your code, without any external frameworks. 🚀 Simple & Familiar Syntax: If you know JavaScript, you'll be writing R2Lang in minutes. ⚡ Easy Concurrency: It leverages Go's goroutines through a simple r2() function. 🧱 Object-Oriented: Supports classes, inheritance, and this. 🌐 Web Ready: Includes a built-in http library for creating web servers and REST APIs, inspired by Express.js. Here’s what the BDD syntax looks like in action: ```r2 // Function to be tested func add(a, b) { return a + b } // The test case itself TestCase "Verify that the add function works correctly" { Given func() { print("Preparing the numbers for the test.") // You can set up context here return { a: 5, b: 10 } } When func(context) { let result = add(context.a, context.b) print("Executing the sum...") return result } Then func(result) { // assertEqual is a helper, not yet a built-in keyword if (result != 15) { throw "Assertion failed: Expected 15, got " + result } print("Validation successful!") return "Test passed" } } ``` 💖 How You Can Help The language is functional, and I've written a full 6-module course to document it. However, it's still a young project with tons of room for improvement. I'd love to get some collaboration to take it to the next level. I'm looking for all kinds of help: Go Developers: To help improve the core interpreter. There are huge opportunities in performance (bytecode VM, JIT), memory management, and implementing new features from the Roadmap (https://github.com/arturoeanton/go-r2lang/blob/main/docs/en/roadmap.md). Language Enthusiasts: To give feedback on the syntax, features, and overall direction of the project. What do you love? What do you hate? Testers: I need people to break it! Write some complex scripts, find edge cases, and report bugs in the Issues (https://github.com/arturoeanton/go-r2lang/issues). Documentation Writers: The docs are there, but they can always be improved with more examples and clearer explanations. This has been a solo journey so far, and I'm really excited about the possibility of turning it into a community-driven project. Check out the GitHub repository to see the code, the full documentation, and the issue tracker. Thanks for taking a look! Any feedback, questions, or stars on GitHub would be amazing. Let me know what you think! <!-- SC_ON --> submitted by /u/ResolutionSmooth5259 (https://www.reddit.com/user/ResolutionSmooth5259)

Curiosity-Driven Encryption: A Collatz Conjecture-Inspired Block Cipher with Real-Time Visualizations
https://www.reddit.com/r/programming/comments/1lw4xpg/curiositydriven_encryption_a_collatz/
<!-- SC_OFF -->I am pleased to announce the release of the Collatz Chaos Cipher, an experimental encryption algorithm inspired by the Collatz Conjecture and informed by principles from chaos theory and signal processing. This project introduces a reversible block cipher that employs: Chaotic iteration mechanisms to enhance unpredictability Non-linear key transformations to increase cryptographic strength A synthesis of classical 3x+1 logic with novel signal spiral dynamics -The resulting ciphertext exhibits strong avalanche characteristics and complex diffusion behavior. In addition to the core cryptographic implementation, the repository includes a suite of visualization tools designed to illustrate bit-level diffusion and waveform transformations across encryption rounds. These tools provide valuable insights into the internal behavior and structure of the cipher. This work is intended as a theoretical and educational exploration at the intersection of mathematics and cryptography. It is not recommended for production environments or security-critical applications. I invite researchers, cryptographers, and mathematicians to review, analyze, and contribute to this open-source project. Your feedback and collaboration would be most welcome.
