## NanoChat – The Best ChatGPT $100 Can Train
**Repo:** [https://github.com/karpathy/nanochat](https://github.com/karpathy/nanochat)
**Author:** Andrej Karpathy
**HN:** 784 points | 155 comments | [Discussion](https://news.ycombinator.com/item?id=45569350)
NanoChat is a **lightweight ChatGPT-style language model** designed for education and rapid prototyping.
Key attributes:
- **Budget:** ~ $100 for a full train; “kindergarten-grade” output quality but functional.
- **Minimal dependencies** and clean code.
- End-to-end pipeline script: ./speedrun.sh # Covers preprocessing → training → inference → web UI
- Runs on eight H100 GPUs; inference fits into 80 GB VRAM.
- Benchmarks: GSM8K accuracy 7.58%, MMLU 31.51%.
- Scalable: d26 deep model (~$300) and larger (~$1000) options possible with parameter tweaks.
**Takeaway:** A hands-on gateway to understanding modern LLMs, with open, hackable architecture.

## WireGuard FPGA – Open, Auditable VPN Hardware
**Repo:** [https://github.com/chili-chips-ba/wireguard-fpga](https://github.com/chili-chips-ba/wireguard-fpga)
**HN:** 618 points | 159 comments | [Discussion](https://news.ycombinator.com/item?id=45559857)
This project implements WireGuard directly on an affordable Artix-7 FPGA, creating a **self-contained VPN appliance** without relying on a host PC.
Highlights:
- **Fully open source**: RTL in SystemVerilog, open toolchains.
- Builds on prior “Blackwire” work but on cost-effective hardware (4-port GbE FPGA board instead of expensive Alveo cards).
- BOOT goal: Transparent, auditable design for security-critical deployments.
- Roadmap: Multi-channel expansion, GUI management, remote testing facilities.

## Google’s Android Sideloading Restrictions
**Article:** [MakeUseOf](https://www.makeuseof.com/androids-sideloading-limits-are-anti-consumer-move-yet/)
**Timeline:**
- Rollout: Oct 2025 start → Sept 2026 partial enforcement → 2027 global.
- Devs must pass **government identity verification** for GMS devices.
- Blocks pseudonymous & niche open-source app distribution.
**Criticism:**
- “Security theater” — existing device security measures (Play Protect) suffice.
- Attacks open ecosystems (e.g., F-Droid apps).
- Raises barriers for grassroots and indie developers.
- Likely to reduce Android's openness advantage vs iOS.

## Free Software Status – “Hasn’t Won” Debate
**Post:** [dorotac.eu](https://dorotac.eu/posts/fosswon/)
**HN:** 361 points | 415 comments | [Discussion](https://news.ycombinator.com/item?id=45562286)
**Argument:**
- FOSS is dominant in developer-facing infrastructure (Linux, Python, Postgres), yet everyday device firmware remains locked.
- Hardware freedom lags; even “open” devices ship with closed modems/firmware.
- True **user autonomy** unmet — echoes Stallman's original printer source-code frustration.
