24 alternatives to Punch card simulator and Fortran IV interpreter

Code: https://github.com/ehrlich-b/punchcards Just for fun, I've only spent a few hours on it so far. What are everyone's punch card emulation needs?

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Punch - Read - Execute. Punch, download, share, submit and execute stacks of virtual punch cards.

    I am excited to announce the launch of my e-book on Graphics/WebGPU programming! This project has consumed much of my spare time, during which I developed various tools to facilitate the publishing process, including a code playground and a static site generator that can reference sample codes. However, I'm feeling burnt out and ready to call it finished, even though it may not feel completely done. Avoiding another abandoned side project has been my primary motivation in reaching this point.

    A while back I wrote a CHIP-8 emulator (which is considered the Hello, World! of emulators and is more accurately a virtual machine since historically CHIP-8 was an interpreted language running on top of the COSMAC VIP to make game programming easier). But a few months ago I got really interested in embedded software, so decided it would be neat to port my emulator to a STM32 MCU and design a console around it as a learning experience, since CHIP-8 never existed as a physical system. I didn't know much about embedded software when I began, and even less about electronics, but I managed to…

    I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

    This is my first emulator. It is still missing a few bells and whistles like the sound timer, but otherwise it passes the basic tests from Timendus (https://github.com/Timendus/chip8-test-suite). I've also been thinking about making a Fortran dialect suitable for CHIP-8 (https://fortran-lang.discourse.group/t/fortran-chip-8-interp...).

    VSCode extension with games (Snake, Plinko, slots), HN/LessWrong reader, and Pomodoro timer for AI coding wait times. Fake currency only. Marketplace: https://marketplace.visualstudio.com/items?itemName=TouchGra... Built in a week with Claude Code after seeing Chad IDE get ratio'd for integrating real gambling. Happy to answer questions or get roasted on the code.

    I participated in the Nvidia + Vercel 2 hour hackathon in SF tonight, and built something I've wanted, but hadn't tried building. I implemented an MCP Server and VS Code extension to allow Claude Desktop to place breakpoints, step through code, and execute expressions (assuming language support). So you can ask it a question that requires actually stepping through the code and now it can actually do that - check values for you, etc. It's _definitely_ not perfect. Have improvements? Please make a PR!

    Hi HN, I built Card-Snap: www.card-snap.com It’s a very simple tool where you upload a document (Word, PDF, TXT), and it generates a PDF file with printable flashcards. The idea came to me when helping my daughter study science. I realized that while there are many digital flashcard apps, it’s not easy to get physical flashcards without a lot of manual work. Card-Snap is minimal: no signup, no tracking, no ads — just upload, pick how many questions you want, and download the printable cards. I’d love your feedback! Some questions I have: Is the idea useful enough on its own? What features…

    Disclaimer, I have not yet placed the order. But JLCPCB have so far excepted all files and config so I have 1 more button to press. If anyone see some obvious mistake please send feedback. This project grew out of curiosity. Loved the https://monster6502.com/ project but that is on another level. Here I tried to stay "reasonable" and added a Raspberry Pico 2 W on the back to drive it all. But also, was curious if Claude could pull this off. Guess I will have to place that order to call the cards.

    I built this mostly because I love the intersection of game AI, high-performance computing, and poker. I’d love for anyone interested in game theory or CUDA optimization to tear it apart, test the accuracy, and give me feedback. Happy to answer any questions about the algorithms, the transition from CPU to GPU, or poker AI in general!

    A little game I made to show off an old project. The functionality of the CPU is derived entirely from simulated logic gates. All the operations and control flow are based on the underlying properties of the logic gates, and changing their operation leads to corresponding changes in function. The original game code is all python and it runs in the browser using wasm/pyodide. Not very mobile friendly

    Hey HN, I built a tool that takes a photo or scan of your handwritten text and converts it into a stroke-by-stroke animation. The goal is to preserve the personal feel of handwriting while making it easy to share digitally. Here’s a short demo note if you want to see it in action: https://www.handwritten-cards.de/cards/ff8d6fe46e62fe48773f3... I’d love any feedback on whether you find this useful, potential features you’d like to see, or ways to improve the interface. It’s free to try, and I’m open to all suggestions. Thanks for checking it out!

    I built LunarBasic because I wanted a modern recreation of BlitzBasic from back in the day. I wanted it to have good step debugging features, and I wanted it to compile down to a native binary with no external dependencies. I do know there's an open source BlitzBasic out there but I wanted something simpler and more concise. It does have a "pro" feature set, but for the foreseeable future, anyone joining up will have the pro version in perpetuity (eg I'm not trying to sell anything here). It's early (v0.8.0). Would love feedback on the language design and compiler output, especially from…
