📻 I built Lost Frequency Radio: an old radio that picks up broadcasts from parallel universes, written live by a 1-billion-parameter model running entirely on CPU. No cloud APIs. Nothing leaves the machine. You turn a dial and hunt for voices in the static: a 1950s announcer calling a chess match between cats, a weather report for Jupiter, a number station reading numbers in Morse. Break its cipher and the dial grows, revealing every station was a room in the same collapsing universe. Under the hood: a fine-tuned MiniCPM5-1B (LoRA, trained on my laptop), quantized to GGUF and served through llama.cpp, behind a hand-built CRT interface using gradio.Server (no default Gradio UI in sight). Built for the Hugging Face Build Small Hackathon 2026. Small models, big fun. ▶ Try it: huggingface.co/spaces/build-… 📓 How I built it: huggingface.co/blog/build-sm… #AI #HuggingFace #MiniCPM #SmallModels #LocalAI #BuildSmallHackathon @OpenBMB @huggingface @Gradio @ollama

The most critical feature: the model acts as the technical director. It is trained to output structural markers (like [JINGLE] or [INTERFERENCIA]) that directly dictate the Gradio frontend state and trigger the TTS execution timing.

Cybersecurity is no longer optional in Web3. As the Solana ecosystem scales, secure smart contracts, wallet protection, and continuous auditing are what separate sustainable projects from tomorrow’s headlines. 🚀🔒 Build fast. Secure first. #Solana #CyberSecurity #Web3 #Blockchain

380 projects were submitted for the @dev3pack global hackathon We hosted this hackathon with a small budget, but created a global movement, online and IRL in 40 local hubs, even in bear market. The community showed up not for prizes, but for collaboration, learning, building startups, and getting recognized. We wanted to bring our own audience, and managed to onboard 4K applicants from 84 countries and 1,700 universities. For most of them, it was their first hackathon ever! The hackathon became one of the biggest student onboarding initiatives on @solana. Their official student hackathon had around 90 submitted projects, with a different budget. The secret? Infrastructure and community. In just a few weeks, with @armolas_06 & @zintarh_dev, we built a cool platform to support the entire hackathon experience, from participation to event coordination. More than 150 people helped organize this movement. Huge thanks to all of them! The energy from emerging markets is unmatched. Many participants are already pushing their projects further, forming teams, and taking the lead in their local ecosystems. Every project received AI deep feedback and recommendations (product, technical) thanks to @bonfiresai Today it's an exciting day for all of them, as we are opening our global accelerator with @solana to support their founder journey 🫡

nobody talks about how lonely it feels to be excited about tech when the people around you don’t get it. that’s why finding your community changes everything #tech

24, still in uni, already patching vulnerabilities in open source software. not saying this to flex. saying it because a year ago i didn’t think i was ready either. you’re more ready than you think. #AI #growth

One interesting finding from building Griffin: The "Polyglot" attacker is surprisingly effective. Most AI agents have semantic guardrails, but they completely fall apart when the same malicious intent is wrapped in Base64 or obfuscated XML.

We’re trusting autonomous AI agents with live mainnet wallets, yet we’re still managing their keys like it's 2021. Remember… Sticking a base58 private key in a .env file for a Python script isn't security !! #mainnet #ai #crypto #aisec #security #onchain

Local fee markets on Solana don't get enough credit. The fact that a massive NFT mint or a meme coin frenzy doesn't halt the entire network anymore is the actual engineering moat, tbh predictable execution > raw speed #solana #OnChain #network

Autonomous AI agents on Solana are scaling fast, but the infrastructure to secure their on-chain interactions is lagging. For the @colosseum Frontier Hackathon, I built Griffin: an adversarial security platform for AI agents. Built from scratch in 48 hours. 🧵👇

To improve the consumption of these audits, I integrated @ElevenLabs to synthesize an executive audio briefing of the critical findings.
