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)

Chaotic AI Tool Pricing: Limits Cut, Token Metering
https://www.reddit.com/r/programming/comments/1m6wvfo/chaotic_ai_tool_pricing_limits_cut_token_metering/
<!-- SC_OFF -->AI tool pricing is a mess! Limits get cut without warning. Token meters pop up on every prompt. I spend more time guessing costs than writing code. Why it matters You stop to check token use and lose focus Bills jump up and ruin budgets If vendors earn per token, they won’t build better caching or smarter models New fad of outcome-based pricing (pay per bug fixed or feature done) sounds nice but is hard to track. Traditional seat-based pricing works best You know the monthly cost as a user Vendors shouldn't punt their solution inefficiencies on to their users Would love to know what you all think! <!-- SC_ON --> submitted by /u/West-Chocolate2977 (https://www.reddit.com/user/West-Chocolate2977)

[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)

We maintain HarfBuzz, the text shaping engine used in Chrome, Firefox, Android, and more — Ask us anything (or tell us what confused you)
https://www.reddit.com/r/programming/comments/1m6a7xo/we_maintain_harfbuzz_the_text_shaping_engine_used/
<!-- SC_OFF -->Hi r/programming (https://www.reddit.com/r/programming), We’re the maintainers of HarfBuzz, the open-source text shaping engine used by browsers, operating systems, and applications to render all text, including supporting scripts like Arabic, Devanagari, Khmer, CJK, and more. HarfBuzz is known for being fast, portable, and complete. But it’s also sometimes seen as hard to understand or work with, especially if you’ve ever: Tried integrating it into your own rendering stack Stepped through the shaping pipeline in a debugger Opened the source and thought “wait, what the heck is going on here?” Tried to modify or extend it and hit unexpected roadblocks Compared it to other shaping engines Tried to port it to another programming language Wondered why you need such a “huge” dependency
We’re working on a Developer FAQ and Design Notes to clear up misconceptions and explain the "why" behind our more unusual design decisions (yes, the macros are intentional). So we’re asking: 🧠 What was your biggest WTF moment reading or using HarfBuzz? Other things we’d love to hear about: Which parts felt like magic or a black box? What do you think we could explain better? Have you run into performance or integration surprises? Are there features you only discovered by reading the source? What do you wish the documentation had told you? Anything else you want to know about the project? We'll answer questions here and also open a GitHub Discussion afterward to collect and respond to feedback more formally and integrate into our documentation. Thanks in advance for your curiosity, stories, or frustration—we’re listening! <!-- SC_ON --> submitted by /u/behdadgram (https://www.reddit.com/user/behdadgram)

<!-- 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)

Reverse Proxy Deep Dive: Why HTTP Parsing at the Edge Is Harder Than It Looks
https://www.reddit.com/r/programming/comments/1m6gqnq/reverse_proxy_deep_dive_why_http_parsing_at_the/
<!-- SC_OFF -->I previously shared a version of this post on Reddit linking to Medium, but since then I’ve migrated the content to my personal blog and updated it with more detailed insights. This is Part 2 of my deep dive series on reverse proxies, focusing on the complexities of HTTP parsing at the edge. The post explains why handling HTTP requests and responses isn’t as simple as it seems, especially when dealing with security, performance, and compatibility at scale. I cover topics like malformed requests, header manipulation, user-agent quirks, geo-IP handling, and the trade-offs proxies make to keep traffic flowing smoothly and safely. If you’re into web infrastructure, distributed systems, or proxy design, I think you’ll find this useful.
