I added a LeetCode Premium feature (free Time/Space Complexity) to my extension that syncs your solutions to GitHub.
https://www.reddit.com/r/programming/comments/1m7wgcw/i_added_a_leetcode_premium_feature_free_timespace/
<!-- SC_OFF -->Hey everyone, TL;DR: I built a free Chrome extension called leetpush that automatically saves your LeetCode solutions to GitHub. The new update adds a free Time & Space Complexity Analyzer (like LeetCode Premium) and coding memes for fun. Like many of you, I'm constantly on LeetCode preparing for interviews. I got really tired of two things: manually copying my code to create a GitHub portfolio and not knowing my code's efficiency without paying for Premium. So, I built a tool to fix it. It's called leetpush. What does it do? Automatic LeetCode to GitHub Sync: Solved a problem? Bam. It's instantly committed to your GitHub repo. It's the easiest LeetCode GitHub integration you'll find. [NEW] Free Complexity Analyzer: This is the big one. After you solve a problem, the extension shows you the Time and Space Complexity (Big O notation). This is a game-changer for interview prep and something you normally have to pay for. It’s the perfect LeetCode Premium alternative for performance analysis. [NEW] Coding Memes: After a successful submission, it shows you a relevant meme. Because why not have a little fun while you grind? I’m committed to keeping this tool 100% free and open-source. My goal is to help students and developers save their LeetCode solutions and learn more effectively. Since this is a passion project, I’m not putting up a paywall. Instead, if you find the tool genuinely useful for building your coding portfolio or for the free complexity analysis, I've set up a "Buy Me a Coffee" page. Any support would be incredible and will help me cover server costs and keep developing new features. Links: Install on Chrome: leetpush on Chrome Web Store (https://chromewebstore.google.com/detail/leetpush/fppdnbfkhpmppifbmmchnhpnmmickbin) Source Code & Details: GitHub Repository (https://github.com/singhJasvinder101/leetpush) I'd love to hear your feedback. What do you think? Any features you'd like to see in the next LeetCode automation update? Thanks for checking it out! <!-- SC_ON --> submitted by /u/Best-Ad7408 (https://www.reddit.com/user/Best-Ad7408)

Built a macOS app solo →$3.6K revenue, 5.3K users, $0 ads, and total chaos (in a good way)

<!-- SC_OFF -->Launched Wallper just over a month ago — a clean, native 4K live wallpaper app for Mac.
I built it because every other option felt slow, ugly, or non-native.
So I wrote it from scratch in pure Swift, optimized for performance, no login, no tracking, no BS.Highlights What's happened since launch: 👨💻 Solo dev, 3 months of work 💳 415 lifetime purchases → $3,600 revenue 💻 5,300 users 🌐 43,000 website views 🔁 9 updates shipped 📢 $0 on ads — all growth from Reddit, Product Hunt, and Telegram 📉 3 refunds 🔍 First page of Google for “Wallper” (which was not easy) The crazy part: 💬 Reposted by 3 Telegram channels with 2M+ subs 🧑🏫 Got emails from university professors asking to analyze the app 🤝 Dozens of collab/investment offers 📰 Written about on multiple news sites 🔒 Multiple attempts to DDoS or reverse-engineer the app (fun times) It’s been wild.
Didn’t expect a simple macOS wallpaper app to get this much attention — but here we are.
If you're building solo: polish matters, transparency matters, and posting in the right places still works. Happy to share what worked if you're in the trenches too. <!-- SC_ON --> submitted by /u/Accomplished-Bus5639 (https://www.reddit.com/user/Accomplished-Bus5639)

Why is the a difference between the LLMs evaluation benchmark score and its users response?
https://www.reddit.com/r/programming/comments/1m70kfg/why_is_the_a_difference_between_the_llms/
<!-- SC_OFF -->Why is a model scores so high on the leaderboard but its respective chatbot version tends to give 'bad' (for example, inaccurate) responses? For example, If you ask DeepSeek R1 chatbot to calculate:
9.11-9.9
It gives a correct answer, but the journey to get to that answer is all over the place, like it calculate the tenths and hundredths places to 2 and 1, which comes to -0.21, but the final answer it arrives somehow turns into -0.79, it's like it just copy the answer somewhere else and doesn't take logic into consideration. Or another example, Google's Gemini latest 2.5 Pro model, same question, but this time, the model outright gives the incorrect answer (-0.21) and refuse to admit its fault, even after i asked it to use an external tool, a calculator.
And another time when i put in an Odoo code snippet and asked if that code is usable in an earlier version, it gives back another incorrect response so i have to take it to ChatGPT in order get a correct answer. So what gives? Can someone with expertise give me an explanation? <!-- SC_ON --> submitted by /u/No_Consideration8074 (https://www.reddit.com/user/No_Consideration8074)

[Seeking Collaborators] Building a Physics & Reality Simulation from First Principles - An Open Source "Matrixgame"
https://www.reddit.com/r/programming/comments/1m6v5hv/seeking_collaborators_building_a_physics_reality/
<!-- SC_OFF -->Hey r/programming (https://www.reddit.com/r/programming), I'm reaching out today to find like-minded individuals for an ambitious open-source project I'm calling the "Matrixgame." The core idea is to build a simulation engine, but with a twist. Instead of relying on existing frameworks like Unity or Unreal, the goal is to build it from absolute first principles. We start not with graphics, but with foundational axioms and see what kind of complexity can emerge. The Vision (The "Why") This project is a fusion of programming, physics, and philosophy. It began as a thought experiment: could we define a minimal set of rules from which a universe resembling our own could emerge? We're starting with concepts like: Axioms: "Existence" itself is the baseline. "Consciousness" is an active agent that can influence the system. Core Dynamics: A principle of "Entropy" (defined as randomness with a tendency toward equilibrium) is balanced by a principle of "Complexity Preservation." Emergent Structures: The expected outcome of these competing forces is the natural formation of self-similar, fractal structures at every scale. The ultimate goal is to create a unifying model—a "digital petri dish"—to test how fundamental laws can give rise to complex phenomena. The Current State & The Technical Challenge This isn't just an abstract idea. The initial framework is already conceptualized: The simulation runs in discrete time steps (a causal chain). The universe is populated by mass-points, each defined by a simple state vector (mass, position, velocity). Interactions are governed by fundamental laws, starting with the inverse-square law (I∝1/r2). The entire system is defined using SI base units to keep it grounded in real-world physics. The immediate programming challenge is building the core simulation loop—an efficient N-body simulation that can handle a vast number of interacting points and execute the custom rules of our universe. Who I'm Looking For This project is too big for one person. I'm looking for collaborators who are excited by this intersection of code and concept. You could be a great fit if you are: A programmer with a strong interest in physics, or a physicist who loves to code. Someone with experience in building simulations, game engines, or scientific computing. An algorithm designer who enjoys challenges like optimizing N-body problems or designing systems for emergent behavior. Passionate about data visualization—a huge part of this will be observing the structures that form. A philosopher, thinker, or visionary who can challenge and expand the conceptual framework and ensure the model's logic is sound. The Goal The goal is to create a flexible, open-source framework where we can collectively experiment with the fundamental parameters of reality. It’s a coding project, a scientific experiment, and a shared work of art. If this idea excites you—if you've ever wanted to build a universe from scratch just to see what happens—I'd love to hear from you. How to Join? Comment below with your thoughts, ideas, or area of expertise/interest. Feel free to send me a DM to discuss this further. If we get enough interest, I'll set up a GitHub repository and a Discord server to get the collaboration started. Thanks for reading. Let's build something amazing together. TL;DR: I'm starting an open-source project to build a reality simulation from foundational principles (physics, entropy, consciousness). Looking for programmers, physicists, and thinkers to collaborate on everything from the core algorithms to the philosophical rules. Interested in building a universe from scratch? Let's connect. <!-- SC_ON --> submitted by /u/ConquestMysterium (https://www.reddit.com/user/ConquestMysterium)
