Show HN: Code Mind Maps – A Fresh Perspective on Code Navigation https://ift.tt/uHXoq7i

Show HN: Code Mind Maps – A Fresh Perspective on Code Navigation For years, I’ve been obsessed with mapping code visually — originally by copy-pasting snippets into FreeMind to untangle large code bases in big complex projects. It worked, but it was clunky. Now, I’ve built a VS Code/Visual Studio extension to do this natively: Code Mind Map. You can use it to add selected pieces of code to a mind map as nodes and then click to jump to the code from the map. Developers say it’s especially useful for: Untangling legacy code Onboarding into large codebases Debugging tangled workflows Please try it out and let me know what you think! https://ift.tt/B1wrdoM July 22, 2025 at 12:39AM

Show HN: A Hard SF Novel About Consciousness and Quantum Neural Interfaces https://ift.tt/hbZ9nmr

Show HN: A Hard SF Novel About Consciousness and Quantum Neural Interfaces I've just completed the first book in a hard science fiction trilogy that explores the technical feasibility of consciousness transfer using cutting-edge semiconductor physics and quantum computing. The Core Technology Stack: The novel centers around PhantaField Inc., a startup developing consciousness preservation through: • 2D Semiconductor Fabrication: Low-temperature MOCVD (Metal-Organic Chemical Vapor Deposition) producing atomically precise tungsten diselenide and molybdenum disulfide layers for quantum processing • 3D Monolithic AI GPUs: Vertically stacked 2D materials with high-density via interconnects, achieving >1 trillion transistors per cubic centimeter • Non-invasive Brain-Computer Interface: IR phase array sensors using focused infrared light with beat radio frequency triggered nuclear magnetic resonance for cellular-level neural mapping • Quantum Consciousness Bridge: Bidirectional data transfer between biological neural networks and quantum processing arrays, enabling permanent cognitive enhancement • Light Field AR Displays: Self-emitting pixel arrays on 2D semiconductor substrates creating direct retinal stimulation with 6+ orders of magnitude bandwidth increase over biological sensory channels The Physics: The story explores the consciousness equation: Consciousness ∝ Dimension × ln(Energy), suggesting that consciousness evolution requires exponential energy consumption to access higher-dimensional awareness. The climax involves a fusion-powered gamma ray laser using a toroidal ring resonator design (inspired by the author's wedding ring geometry) that achieves dimensional barrier penetration through bosonic gamma ray compression—something impossible with fermionic matter particles. Why This Matters: Unlike typical sci-fi hand-waving, every technology described is extrapolated from current research trajectories: 2D materials are already being produced at laboratory scale Brain-computer interfaces are achieving increasingly sophisticated neural mapping Quantum computers are approaching the coherence levels needed for complex consciousness simulation Light field displays are being developed by companies like Magic Leap and Meta Technical Accuracy: I've tried to ground every speculative element in real physics. The gamma ray laser design, for instance, leverages the fact that gamma rays are bosons (unlike electrons) and can theoretically be compressed to unlimited energy densities without Pauli exclusion limitations. The consciousness transfer protocol addresses the hard problem of consciousness by treating awareness as a quantum field phenomenon rather than classical computation—essentially implementing Penrose-Hameroff orchestrated objective reduction at technological scale. For the HN Community: If you're working on: Quantum computing hardware Advanced semiconductor fabrication Brain-computer interfaces AR/VR display technology Consciousness research Fusion energy You'll recognize many cutting-edge concepts pushed to their logical conclusions. The book asks: If consciousness can survive death through technology, what happens to human society? If we can enhance cognition through quantum-biological interfaces, who gets access? If we can create digital gods, should we? Available now as a complete 75,000-word novel. Would love feedback from the technically-minded HN community on the scientific plausibility and implications.

Too optimistic about near-term consciousness transfer, or are we closer than we think? https://ift.tt/rEoG2c0 July 21, 2025 at 04:00AM

Show HN: NativeSwap – Low cost cross-chain swaps without wrappers or bridges https://ift.tt/KiHgUSN

Show HN: NativeSwap – Low cost cross-chain swaps without wrappers or bridges Hi HN, We’ve been working on NativeSwap.io, a low-cost decentralized cross-chain swap platform. It lets users swap native assets (e.g. BTC <--> DOGE) directly, without using wrapped tokens or centralized bridges. Our goal is to make cross-chain swaps cheaper, simpler, and safer. The platform is fully non-custodial and supports both regular and streaming swaps. Under the hood, it leverages liquidity from protocols like ThorChain and Maya Protocol. Currently, We support the following blockchains: - Bitcoin - Ethereum - BNB Smart Chain - Ripple - Dogecoin - Litecoin - Bitcoin Cash - Zcash - Base - Avalanche - Arbitrum - Dash - Radix - ThorChain - Maya Protocol More are on the way. We currently support Metamask and CTRL as browser wallets, as well as keystore files. Support for additional wallets is in progress. We built this because most solutions either rely on wrapped assets or require trusting centralized bridges - both of which introduce risk. Many existing interfaces also charge high fees. Would love feedback on the product, UI/UX, performance, security assumptions or anything else. Still early, but happy to answer questions and improve! Thanks for checking it out https://nativeswap.io July 21, 2025 at 02:02AM

Show HN: New Audiobook Generator for Nvidia Using Chatterbox TTS https://ift.tt/Biofd65

Show HN: New Audiobook Generator for Nvidia Using Chatterbox TTS I am an audiobook addict that coded this https://ift.tt/D8HAiUg . I am using it all the time and it works nice. I have only bothered to get it working on windows but it should be cross-platform as it uses pyqt, I would be happy for contributors to help get it working on macos and linux and also ATI and other video cards. If you are stuck without a video card I recommend using https://ift.tt/8S9uWV4 it can generate an audiobook in around 4 hours with a decent CPU https://ift.tt/D8HAiUg July 20, 2025 at 03:03AM

Show HN: I built a simple study app and got 60 users so far:') built a simple study app that turns messy notes (images or text) into flashcards + quizzes using gpt-4o. originally made it to help myself focus while studying. launched with a hard paywall to avoid ads or noise. ~60 users so far, mostly from tiktok. curious if this is useful beyond my own use case? https://ift.tt/VhK4zF7 July 19, 2025 at 06:44PM
