🧠 Exploring coding challenge platforms — which ones actually help you grow as a developer?
https://www.reddit.com/r/programming/comments/1oixvcn/exploring_coding_challenge_platforms_which_ones/

<!-- SC_OFF -->Hey folks, Over the past few weeks, I’ve been exploring various coding challenge platforms to understand how they differ — not just in problem sets, but also in how they impact real skill growth for developers. Some focus on interview-style DSA questions, others emphasize language mastery or competitive programming, and a few even encourage collaboration and discussion. I put together a short write-up summarizing what I found useful (and not so useful) across popular platforms — from LeetCode to Codeforces, HackerRank, and others. Sharing it here in case anyone’s interested in comparing experiences or adding platforms I missed:
🔗 Best Coding Challenge Platforms: LeetCode, HackerRank & More (https://sagarnikam123.github.io/posts/best-coding-challenge-platforms/) I’m curious — for those who actively use challenge sites,
👉 Which platform do you feel provides the best long-term learning value?
👉 And which ones are overrated or just “grind traps”? Would love to hear your thoughts — especially from those mentoring juniors or hiring devs who use these platforms regularly. <!-- SC_ON --> submitted by /u/sagarnikam123 (https://www.reddit.com/user/sagarnikam123)

How to create Object copies efficiently in Java without rebuilding them from scratch?

<!-- SC_OFF -->Let's go through a beginner-friendly guide on the Prototype Design Pattern in Java: One of the most practical creational patterns when you need to create new objects by cloning existing ones instead of building them from scratch. This article covers: What the Prototype Design Pattern is (in plain English) Shallow vs Deep Copy — explained with visuals Modern Java 21 code examples (no outdated Cloneable mess) UML diagram & Sequence Diagram for better understanding Common interview questions and FAQs If you’re preparing for Java interviews, learning design patterns, or just want to level up your Java design skills, this will help a lot.

Structuring multi-agent AI systems efficiently
https://www.reddit.com/r/programming/comments/1oiypfv/structuring_multiagent_ai_systems_efficiently/

<!-- SC_OFF -->I’m experimenting with AI agents that must work across multiple messaging apps while remembering context. Using Photon, I could prototype quickly with less boilerplate. How do you usually structure multi-agent AI systems to make them modular, maintainable, and memory-aware? Any recommended patterns or frameworks? <!-- SC_ON --> submitted by /u/Fearless-Confusion-4 (https://www.reddit.com/user/Fearless-Confusion-4)

Disasters I've seen in a microservices world, part II
https://www.reddit.com/r/programming/comments/1oj1i7i/disasters_ive_seen_in_a_microservices_world_part/

<!-- SC_OFF -->Four years ago, I wrote Disasters I've Seen in a Microservices World. I thought by now we'd have solved most of them. We didn't. We just learned to live with the chaos. The sequel is out. Four new "disasters” I've seen first-hand: #7 more services than engineers #8 the gateway to hell #9 technology sprawl #10 when the org chart becomes your architecture Does it sound familiar to you? <!-- SC_ON --> submitted by /u/joaoqalves (https://www.reddit.com/user/joaoqalves)
