Show HN: Whole-home VPN router with hardware kill switch (OpenWrt and WireGuard) With internet censorship and surveillance on the rise, ie; UK Online Safety Bill (July 2025) and Australia's social media legislation (Dec 2025) introducing mandatory age verification (read: initial step on the pathway to social credit), I wanted a privacy-first solution that protects browsing history from ISPs and third-party verification services, but not one that requires you to be an Einstein to deploy. This stack turns a Raspberry Pi (or any OpenWrt-compatible device) into a network-wide VPN gateway. Key features: - Hardware kill switch: VPN down = no internet (not a software rule that can leak) - AmneziaWG obfuscation for DPI-resistant connections - Optional AdGuard Home for DNS filtering - Works for all devices including smart TVs and IoT that can't run VPN apps Not a techie? The README is optimized for AI-assisted deployment. Feed it to your LLM of choice (Claude, GPT, etc.) and it can walk...

Show HN: No Black Friday – A directory of fair-price brands The idea came from noticing how many brands inflate prices only to discount them later. Some companies refuse to do that, and I wanted a place to highlight them. If you know a company that doesn’t participate in Black Friday or similar discount events, please add it or share it here. I’d love to grow the list with help from the community. Manuel https://ift.tt/mGpokXr November 28, 2025 at 04:20AM

Show HN: ZigFormer – An LLM implemented in pure Zig Hi everyone, I've made an early version of ZigFormer, a small LLM implemented in Zig with no dependencies on external ML frameworks like PyTorch or JAX. ZigFormer is modelled after a textbook LLM (like GPT-2 from OpenAI) and can be used as a Zig library as well as a standalone application to train a model and chat with it. This was mainly an educational project. I'm sharing it here in case others find it interesting or useful. Link to the project: https://ift.tt/X3JLA2S November 27, 2025 at 11:19PM

Show HN: A New Mnemonic Scheme – Seedless, Passphrase-Sealed, Builtin Multichain TL;DR: Today’s mnemonics are bare keys with no cryptographic protection. MSCIKDF adds passphrase-sealing, seedless operation, and multi-curve support in a single derivation scheme. The user's exposure to compromise/leakage risk can be periodically reset, marking a significant advancement in cryptographic security. In the first half of 2025, more than $1.7B in crypto assets were stolen, and roughly 70% of those incidents involved mnemonic-compromise pathways. The core problem is structural: today’s mnemonics are bare assets—whoever sees them immediately owns everything, and there is no cryptographic-level protection, no rotation model, and no way to safely evolve toward PQC. I built MSCIKDF to directly solve this. MSCIKDF is a cryptographic primitive that introduces passphrase-sealed mnemonics, curve-isolated derivation, and rotatable secrets at the KDF layer. It ensures that: - The seed is never stored...
