My first game built entirely with a local LLM: 🐍⏪ Rewind Snake

🐍⏪ Rewind Snake

Qwen 3.6 35B A3B: the first time for me that a local model has felt both smart AND fast enough to actually be usable.  **Win sats!** * 10,000 sats to the highest score on Normal Mode * 10,000 sats to the highest score on Enhanced Mode Play it here: [https://rolznz.github.io/rewind-snake/](https://rolznz.github.io/rewind-snake/) *To be eligible, enter your lightning address in the high score entry. Winner announced Wednesday morning US.* I one-shotted a snake game to see if it could... then kept pushing to see how far it'd go. * 🔥 Wall Breaker mode * ⏪ a "rewind time" mechanic — pay to undo your death * 🏆 online high scores + replays * 📱 mobile support + PWA Making a game was just a test. What I really have been after is self-sovereign AI - building on a mid-tier laptop is now possible. **My setup:** Qwen3.6-35B-A3B-UD-IQ3\_XXS on a single NVIDIA RTX 4060 mobile — 8GB VRAM (A mid-tier laptop graphics card) Using llama.cpp, built from source: ./build/bin/llama-server -m Qwen3.6-35B-A3B-UD-IQ3\_XXS.gguf -ngl 99 -np 1 -fa on -ctk q8\_0 -ctv q8\_0 -c 131072 --host 0.0.0.0 --port 8088 -ncmoe 38 --no-mmap (Any ideas how I can optimize it more? MTP was not successful for me - 15% faster but much higher memory usage) I built the app with PI agent. It's great for local-LLM dev because it doesn't waste context. I also connected PI agent to Alby's builder and payments skills. Now I can build payment apps, and my agent can have budgeted, private access to my wallet. I also built a simple "second brain" — a place to brainstorm and dump ideas without being spied on. Looking forward to more self-sovereign AI experiments!

I built a small PWA for instantly topping up a debit card with bitcoin and make payments with Apple Pay, which helps me live on bitcoin. Before I start: I do pay directly in bitcoin where possible. This is one of my fallback approaches that in my opinion is sustainable. This is also not a post about KYC or no-KYC, or Apple Pay, or Google Pay, really. This post is also not about crypto, it's about living on bitcoin in a way that actually has a good user experience. I have been doing this for a long time with 2fiat card connected to Apple Pay (I have a small PWA for instant 2fiat lightning topups), but after some repeated problems I needed a fallback, and realized Satora enables a nice flow that works with many different debit card providers. The problem: - I keep funds in a self-custodial bitcoin wallet - Most merchants still accept only card or fiat payments - Most debit cards are not bitcoin-native and do not support the lightning network Satora fixes this with near-instant atomic lightning<->stablecoin swaps. I can keep using bitcoin, and topup my debit card just before I pay. NWC @Nostr Wallet Connect enables a super-simple interface on my phone that I can open and press one button to top up my debit card from my bitcoin lightning wallet. The swap takes less than 10 seconds, and my debit card balance tops up within a minute. How It Works - Setup once: Input your card’s deposit address, network, and currency, then connect your wallet via Nostr Wallet Connect (NWC). This is the only time you are exposed to "crypto". From a UX perspective after that, it's only bitcoin and a USD debit card balance. - Swap via Satora.io: Tap “Top Up” to trigger a Lightning-funded swap. BTC is converted and sent to your card's deposit address. - Seamless payment: NWC pays the Lightning invoice automatically through a budgeted connection to your lightning wallet. Questions for people trying to live on bitcoin - Do you use a bitcoin/crypto/prepaid card today? Which one? - How do you top it up now? What is the annoying part? - Do you keep a balance on it, or top up only when needed? - What would stop you from testing this with a small amount? Early Access to the App - Want to be one of the first to try the app? send an email to hello@getalby.com Your bitcoin stays in your wallet until you need it. Works best with @Alby Alby Hub:

Today many bitcoiners are all still using on Twitter. We pay Elon for reach. Our posts are not even signed with our own keys. This is complete trust in a third party. I don't think Nostr is the solution for a Global Town Square. If you disagree say why. But does anyone care?

I made a big wave surfing game with Opus 4.7. I tried to vibe code the same a year ago, and I couldn't get an ocean to render properly. Play it here:

I built an open social protocol where every interaction is a bitcoin transaction: - Posts, replies, reposts - Follows & unfollows - Profile updates It's called OP_RETURN Social (ORS) Try the reference client for free here: https://opreturn.social - All interactions are published to testnet (Mutinynet) - Optionally pay to publish posts you want to preserve to Mainnet Free transactions will be shown by a gray box icon, instead of an orange one. ORS is "BIP-110 compatible" by concatenating 80 byte OP_RETURN outputs from multiple transactions. The cost to do this is negligible. OP_RETURN is a provenly-prunable way to embed arbitrary data in bitcoin without bloating the UTXO set. Any ORS post FUNDS the network. I think there are some fun things to be explored, especially around WoT & reputation, to both reduce spam and create quality feeds. I also plan to add notifications, reactions, and search next. Everything is open source - If you're interested about the protocol, you can learn more about it ORS here:
