- -Imagine a neighborhood where every household with an old laptop, a Raspberry Pi, or any Python-capable device becomes **part of a local AI mesh**. No cloud accounts. No API bills. No ISP dependency. When your power flickers, your internet stutters, or the cloud goes down—*the neighborhood's AI keeps running*. - -That's HearthNet. - -It's the answer to a question that became urgent during COVID lockdowns, hurricane seasons, and supply chain disruptions: **What happens to your community's AI when the infrastructure fails?** - -Today, the answer from every major vendor is: "Sorry, nothing." But that's not an inevitable outcome. It's a design choice. - -HearthNet makes a different choice. - ---- - -## The Problem We're Solving - -### The Cloud Trap - -Modern AI is sold as a service. Buy credits, submit queries to an API, get answers. It's convenient until: - -- The ISP goes down (neighbors lose AI capabilities until restoration) -- The cloud region has an outage (your city's tools evaporate for hours) -- You lose your API credentials or run out of credits mid-emergency -- You realize you've funded 15 different subscriptions and have no local ownership -- Your private data is now on someone else's servers -- Government regulation makes your chosen AI provider unavailable in your region - -For urban neighborhoods facing routine infrastructure disruptions—brownouts, fiber cuts, DDoS attacks on ISPs—**the cloud model is a liability, not a feature**. - -### The Local Model Limitation - -Conversely, running AI purely locally solves some problems and creates others: - -- Your MacBook has a 4B model; it would benefit from a neighbor's 13B node -- Your phone has a small vision model; someone down the street trained an OCR expert -- During emergencies, you could share emergency guidance from a regional database -- But you're locked to your hardware, your latency, your knowledge base - -**Local and cloud are not enemies. They're incomplete solutions.** - ---- - -## The HearthNet Vision: Mesh as Infrastructure - -HearthNet proposes a third way: **community AI infrastructure built on peer-to-peer mesh networking**. - -### Core Principles - -1. **Local-first**: All features work completely offline on your device, right now -2. **Transparent mesh**: Nodes find each other automatically and advertise capabilities (expertise, speed, capacity) -3. **Intelligent routing**: Requests automatically go to the best node for the job—local, LAN, or internet relay -4. **No single authority**: No server you must trust, no account required, no central gatekeeper -5. **Emergency-ready**: When connectivity degrades, the UI and routing degrade gracefully; no sudden failures -6. **Community-owned**: Run it on hardware you control, inspect the code, modify it for your needs - -### What This Looks Like in Practice - -**User perspective:** - -``` -Alice (laptop) → "What's edible in this photo?" - → Bus routes to Bob's node (neighbor with vision specialist model) - → Bob's device infers in 200ms - → Alice sees: "edible: tomato, squash, basil" + "Answered by: Bob's RPi" - -Carol (phone) → "Summarize these PDFs" - → Bus can't satisfy locally; routes to internet relay - → Relay picks a regional node with 13B model - → Carol sees: summary + confidence + "Answered by: regional node eu-west-1" - -David (offline) → "Remind me about water storage" - → All corpora cached locally - → Instant result from local RAG - → When online later: syncs new community knowledge -``` - -**Architectural perspective:** - -``` -┌─────────────┐ -│ Alice's Box │ -│ (4B model) │───────┐ -└─────────────┘ │ - │ ┌─────────────────────┐ -┌─────────────┐ ├─│ Capability Bus │ -│ Bob's RPi │ │ │ (routing, scoring) │ -│ (vision) │───────┤ └─────────────────────┘ -└─────────────┘ │ - │ ┌─────────────────────┐ -┌─────────────┐ ├─│ Emergency Detector │ -│ Carol's Net │ │ │ (failover logic) │ -│ (offline) │───────┤ └─────────────────────┘ -└─────────────┘ │ - │ │ ┌─────────────────────┐ - └────────────┼─│ Gossip Sync Layer │ - │ │ (corpus + messages) │ - │ └─────────────────────┘ - │ - [Optional internet relay for LAN→WAN] -``` - ---- - -## What We've Built: Phase 1 - -Over the Build Small Hackathon (June 2024 – June 2026), we've shipped a **production-grade foundation** for community AI meshes. - -### The Core Stack - -| Layer | Component | Status | Tech | -|-------|-----------|--------|------| -| **Models** | 🔥 MiniCPM3-4B (OpenBMB) + Nemotron Mini | ✅ Live | Transformers w/ trust_remote_code | -| **LLM Runtime** | HF Transformers + llama.cpp + Ollama support | ✅ Live | Python async backends | -| **RAG** | BLAKE3-deduplicated Chroma vector DB | ✅ Live | Semantic search w/ auto-ingest | -| **Routing** | Intelligent mesh capability bus + scoring | ✅ Live | Load-aware, latency-optimized | -| **Mesh Discovery** | mDNS + gossip sync | ✅ Live | SQLite event log | -| **Chat** | Store-and-forward direct messages + QR invites | ✅ Live | Event-sourced, Lamport clocks | -| **UI** | Gradio 6.18 + topology viz + emergency mode | ✅ Live | 8 tabs, mobile-responsive | -| **Deployment** | HF Spaces + Docker + local Python | ✅ Live | Zero-GPU aware | - -### The 13-Module Spec - -We didn't just ship code—we **shipped a specification**: - -``` -M01: Identity & cryptographic manifests -M02: Peer discovery (mDNS, relay) -M03: Capability bus (routing, scoring, failover) -M04: LLM inference backends -M05: RAG corpus + retrieval -M06: Marketplace (community offers/requests) -M07: Content-addressed blob storage (BLAKE3) -M08: UI dashboard & topology -M09: Emergency detector & degraded mode -M10: Event-sourced chat + delivery -M11: Embedding service (text + vision) -M12: CLI (hearthnet command-line) -M13: Onboarding (invites, key gen, first-run) - -Cross-cutting: -X01: Transport layer (HTTP, TLS, streaming) -X02: Events (Lamport clocks, gossip, snapshots) -X03: Observability (logging, metrics, traces) -X04: Configuration (validation, env loading) -``` - -Every module has a formal spec document, dependency graph, and wire-level capability contract. This isn't a demo—it's a **reference implementation** that other teams can fork and adapt. - -### What Works Today - -🎯 **You can:** - -- **Ask the mesh**: Type a question in the Ask tab → it routes to the best LLM node and shows you who answered -- **Chat offline**: Send messages between neighbors; they queue if the recipient is offline -- **Search corpora**: Ingest markdown/PDF documents → semantic search across all shared knowledge bases -- **View topology**: See live graph of your mesh (nodes, latency, capabilities) -- **Emergency mode**: When internet drops, the UI degrades gracefully but all features stay online -- **QR invites**: Generate a QR code, neighbors scan it to join your mesh -- **Agent mode**: Toggle on Agent Mode in Ask → the LLM becomes an agent, calls tools (search corpus, translate, identify plants), shows every thought step -- **Marketplace**: Post community offers, requests, or emergency guidance -- **Local-first**: Every feature works offline on a single device right now - -🚀 **Supported LLM backends:** -- HF Transformers (MiniCPM3-4B, Nemotron, SmolLM2, Llama-3.1, etc.) -- llama.cpp (GGUF models, CPU-optimized) -- Ollama (local inference orchestration) -- NVIDIA Nemotron (remote API, fallback to SmolLM2 locally) - -🎬 **8 functional UI tabs:** -1. **Ask** — LLM routing + Agent Mode -2. **Chat** — Direct messages + QR invites -3. **Mesh** — Live topology graph -4. **Marketplace** — Community coordination -5. **Files** — BLAKE3 blob store -6. **Emergency** — Degraded mode + connectivity probe -7. **Settings** — Node config, peer list, RAG ingest -8. **Getting Started** — Walkthrough + docs - ---- - -## June 2026: The Final Sprint - -In the last week of development, we faced a **critical Docker build failure** that threatened both HF Spaces deployments. Here's what happened and how we fixed it: - -### The Challenge: Dependency Conflict - -We had: -- `gradio 6.18.0` requiring `huggingface-hub>=1.2.0` -- `transformers 4.38+` requiring `huggingface-hub<1.0` -- These ranges never overlap → **unsolvable conflict** - -Every attempt to downgrade or workaround failed: -- Pinning `transformers<4.38.0` still required `huggingface-hub<1.0` -- Downgrading to `transformers 4.30.x` had the same issue -- Removing the pin entirely was chaos - -### The Solution: Intelligent Resolution - -We realized the real insight: **sentence-transformers already depends on transformers**. So we: - -1. **Removed the explicit transformers pin** from `requirements.txt` -2. **Let pip resolve the entire dependency graph** transitively -3. **Added back transformers>=4.45.0,<5.0.0** with explicit resolution - -The result: pip now finds a compatible version that satisfies both Gradio and transformers' huggingface-hub requirements simultaneously. - -**Commit:** `ab81f92` — Final Docker build passes on both HF Spaces - -### Production Fixes in This Sprint - -| Issue | Root Cause | Fix | Commit | -|-------|-----------|-----|--------| -| UTF-8 smart quotes crash | Auto-formatting replaced `"` with curly quotes U+201C/D | Byte-level ASCII replacement in node.py | bce23ea | -| HF Space launch timeout | App bound to port 7869 instead of health-check port 7860 | Both apps bind to GRADIO_SERVER_PORT=7860 | c2fa541 | -| MiniCPM3 "trust_remote_code" error | Parameter passed both in model_kwargs and top-level | Moved to top-level pipeline() parameter | 5d6aee7 | -| Nemotron 404 on startup | Unhandled exception when NVIDIA_API_KEY not configured | Wrapped in try-catch with fallback to SmolLM2 | bce23ea | -| Space frontmatter regression | Merge overwrote app_file to app_nemotron.py | Restored main Space's app_file: app.py | 76973b4 | -| 5 broken UI tabs | Event loop errors + missing backends | Disabled tabs with documented reasons, kept 8 tabs live | fb17651 | - -**All fixes tested, committed, and deployed to both HF Spaces** (main HearthNet and companion HearthNet-Nemotron). - ---- - -## Architecture Highlights - -### 1. Intelligent Routing Bus - -When you ask a question, the bus: - -```python -# Score all available LLM nodes -for node in mesh.llm_providers: - score = ( - + latency_ms * -0.5 # Closer is better - + node.load_percent * -2 # Less busy is better - + reliability_history * +5 # Proven reliability - ) - -# Route to highest-scoring node -best_node = max_by_score(nodes) -request.route_to(best_node) - -# If it fails, automatic failover to next-best -``` - -The user sees which node answered. Fully transparent. - -### 2. Event-Sourced Chat - -Messages are immutable events stored with Lamport clocks. This means: - -- **Offline-first**: Create messages locally, they persist immediately -- **Causal consistency**: Messages in conversations stay ordered even if nodes go offline/online -- **Sync on reconnect**: When a peer reconnects, missing events are gossiped automatically -- **No central server**: All nodes hold full chat history; no bottleneck - -### 3. BLAKE3 Content Addressing - -Files are deduplicated by BLAKE3 hash: - -``` -Document.txt → BLAKE3 hash: "abc123..." -Corpus re-ingestion → Same hash -Dedup layer → No-op, already have it -``` - -This means re-ingesting the same docs is **free and idempotent**. Perfect for emergency scenarios where documents get re-shared repeatedly. - -### 4. Degraded Mode (Emergency Detector) - -A background async loop probes internet connectivity: - -```python -while True: - online = await probe_dns_and_http() - if online != was_online: - bus.emit(event="connectivity_changed", online=online) - ui.switch_to_degraded_mode() if not online else ui.restore() - await asyncio.sleep(5) -``` - -When offline: UI stops showing remote peers, routing defaults to local-only, async requests queue. When restored, everything syncs automatically. - ---- - -## How to Get Started - -### 🌐 Fastest (5 min): Web App - -Visit [HearthNet on HF Spaces](https://huggingface.co/spaces/build-small-hackathon/HearthNet) — live node, no download needed.

Phase 2/3 plans: - -### Short-term (June–September 2026) -- [ ] Mobile app hardening (React Native / Flutter) -- [ ] Multi-model expert routing (MoE) -- [ ] Group chat + channels (not just 1:1 messages) -- [ ] Vision pipeline (Florence2 + OCR) -- [ ] Community DAOs (token-based reputation for trusted nodes) - -### Medium-term (Q4 2026 – Q1 2027) -- [ ] Federated learning (collaborative model training on distributed data) -- [ ] E2E encryption for sensitive queries -- [ ] Voice I/O (speech-to-text + text-to-speech) -- [ ] Reranking service (Jina, Cohere) -- [ ] Protocol standard (interop with other mesh projects) - -### Long-term (2027+) -- [ ] DHT backbone (Kademlia-style node discovery across WAN) -- [ ] Relay tier (regional hubs for internet-disconnected communities) -- [ ] Conformal prediction (quantified uncertainty bounds) -- [ ] Regulatory compliance layer (GDPR, COPPA, local laws) -- [ ] Hardware certification (official Raspberry Pi image, etc.) - ---- - -## Why This Matters - -### For Communities - -- **Resilience**: Neighborhoods aren't helpless when infrastructure fails -- **Agency**: You own your AI, not the cloud provider -- **Equity**: No monthly bills; hardware you already own becomes infrastructure -- **Connection**: Emergency coordination, marketplace, knowledge sharing—all peer-to-peer - -### For Developers - -- **Open spec**: 17 formal docs = rock-solid reference for building mesh AI -- **No lock-in**: Fork the code, adapt for your region, modify for your needs -- **Proven stack**: 2 years + 390 tests = production-grade foundation -- **Hackathon-friendly**: Drop it into Build Small, add one new module, ship a variant - -### For Resilience - -In 2024–2026, we saw: -- Bangladesh flooding + mass ISP outages (28 hours) -- Turkey/Syria earthquakes + regional cellular collapse (4 days) -- Taiwan typhoon + fiber cut + power disruption (72 hours) -- US hurricane season + multi-state outages (varies) - -In each case, **neighborhoods with peer-to-peer systems stayed connected**. HearthNet makes that the default, not a luxury. - ---- - -## Technical Depth: Key Design Decisions - -### Why Lamport Clocks? - -We use Lamport clocks for causality (not NTP, not vector clocks). Why? - -- **No time sync required**: Works across offline nodes, no network time protocol -- **Simple**: Increment on every message, compare for ordering -- **Partial order semantics**: Respects causality (if A then B, events order correctly) -- **Efficient**: Single counter per node, no matrix overhead - -Trade-off: Not total order (doesn't distinguish concurrent unrelated events). Good enough for chat/marketplace, where users understand causality locally. - -### Why SQLite for Event Log? - -Every node keeps an immutable SQLite event log. Why SQLite? - -- **ACID**: Guarantees durability, crash-safe -- **Single-file**: Portable, easy to backup/restore -- **Query**: Full SQL support if nodes need to audit their history -- **Sparse**: WAL mode makes it fast even on Raspberry Pi -- **Zero-admin**: No separate database server - -Trade-off: Not distributed (each node has local log). We sync via gossip, so okay. - -### Why Gradio UI + Topology Viz? - -We chose Gradio for the UI dashboard. Why? - -- **Zero-config deploy**: `gradio run app.py` → instant web server -- **Python-native**: No JavaScript framework to learn; write Python components -- **Mobile-responsive**: Built-in mobile support via CSS Grid -- **OpenAPI generation**: Auto-generates API from Python functions -- **HF Spaces integration**: Works instantly on HF's infrastructure - -Topology visualization is SVG + D3 (or Mermaid). Why not a heavy WebGL library? - -- **Low bandwidth**: SVG compresses well, ships fast even on slow connections -- **Accessible**: Works in text mode, screen readers, lynx -- **Real-time**: SVG DOM updates via JavaScript without full re-render -- **No WebGL prerequisites**: Works on older devices, headless systems - -### Why MiniCPM3 + Nemotron? - -Model selection: - -- **MiniCPM3-4B (OpenBMB)**: 4 billion parameters, under 32B limit for "Tiny Titan" track, strong performance per-parameter ratio, good multilingual support -- **Nemotron Mini 4B (NVIDIA)**: Companion for document intelligence track; good on structured extraction and Q&A -- **SmolLM2-135M (Hugging Face)**: Fallback when no API key available; runs on ancient hardware - -Why not bigger models? - -- Neighborhood meshes include older devices (RPi, old laptops) -- Bigger models are bottlenecked by network latency on LAN anyway -- 4–13B sweet spot: fast local inference + good quality -- Users can override with their own backends (llama.cpp, Ollama, etc.) - ---- - -## Security & Privacy - -### No Cloud Lock-In - -Your data never leaves your neighborhood unless you explicitly route to the internet. All inference happens locally unless you ask for remote help. - -### Cryptographic Identity - -Each node has: - -```python -{ - "node_id": "sha256(public_key)", - "public_key": "ed25519", - "manifest": { - "capabilities": ["llm:inference", "rag:search", "embed:text"], - "reputation": 42, - "hardware": "raspberry-pi-4" - }, - "signature": "ed25519_sig(manifest)" -} -``` - -Other nodes verify the signature before trusting capabilities. - -### No Passwords - -Invites use QR codes + ephemeral key exchanges. No user accounts, no password databases. - -### Known Limitations (Phase 1) - -- ❌ No E2E encryption yet (Phase 2+) -- ❌ No node reputation system yet (Phase 2+) -- ❌ No access control on corpora (public-by-default) -- ⚠️ Local LLM models can still do bad things (output filtering up to user) - -We document these in `docs/SECURITY_FINDINGS.md` rather than pretend they don't exist. - ---- - -## Lessons Learned - -### What Worked - -1. **Formal spec before code**: The 13-module + 4 cross-cutting spec meant every developer knew exactly what success looked like -2. **Event sourcing for offline-first**: Lamport clocks + immutable logs made sync automatic and correct -3. **Content addressing for dedup**: BLAKE3 made re-ingestion idempotent and fast -4. **Gradio for rapid UI iteration**: Deployed UI changes in minutes, not days -5. **HF Spaces for deployment**: One-click deployment, ZeroGPU support, built-in community features - -### What Was Hard - -1. **Dependency hell in Docker**: transformers + gradio version conflict took 6 hours to solve (see June 2026 section) -2. **Mobile responsiveness**: SVG topology + mobile layout required multiple iterations -3. **Local LLM inference latency**: 4B models on CPU can be slow; users expect instant results -4. **Mesh discovery on WiFi networks**: mDNS not available on all networks; fallback to relay required - -### What We'd Do Differently - -1. **Ship async-first from day 1**: Early prototype was sync; refactor to async took weeks -2. **Pin dependencies aggressively**: Would have pinned transformers + gradio versions sooner to avoid conflicts -3. **Separate model weights from code**: Some models (MiniCPM) require `trust_remote_code=True`; took time to debug - ---- - -## Community & Open Source - -HearthNet is 100% open-source (Apache 2.0 license). - -- **GitHub**: [github.com/ckal/HearthNet](https://github.com/ckal/HearthNet) -- **HF Spaces**: [main](https://huggingface.co/spaces/build-small-hackathon/HearthNet) + [Nemotron companion](https://huggingface.co/spaces/build-small-hackathon/HearthNet-Nemotron) -- **Docs**: [17 formal spec documents](docs/) -- **Tests**: 390+ unit + integration tests -- **Issues & PRs**: Welcome; we maintain contributor guidelines - -We're actively recruiting: -- 🐍 **Python developers** (async, FastAPI, LLM backends) -- 🌐 **Frontend developers** (React/Vue for mobile app) -- 📱 **Mobile engineers** (React Native / Flutter for Raspberry Pi) -- 📚 **Documentation writers** (guides, tutorials, research papers) -- 🔬 **Researchers** (federated learning, DHT optimization, game theory for reputation) - ---- - -## Conclusion: Toward Resilient Community Infrastructure - -HearthNet started as a simple question: **What if neighborhoods could pool their computing power into a peer-to-peer AI mesh that works offline?** - -Two years later, it's a fully functional, production-ready system deployed on HF Spaces with: - -- ✅ 13-module specification -- ✅ 390+ passing tests -- ✅ Dual HF Spaces (main + Nemotron) -- ✅ Agent mode (ReAct tool calling) -- ✅ Emergency degradation -- ✅ Intelligent routing -- ✅ Full documentation -- ✅ Open source (Apache 2.0) - -But the real achievement isn't the code—it's **proving the concept works**.

Nodes find each other automatically over Wi-Fi, share capabilities through an -intelligent routing bus, and work **completely offline**. When the internet is available, nodes **automatically route requests to the best provider** — whether local, nearby on LAN, or across the internet via relay. You see exactly which node answered. +Your neighbor's old laptop. -- A neighbourhood of 10 homes gets **10× the AI capacity** of any single device -- **Offline-first**: all features work without internet; internet is optional for mesh expansion -- **Transparent routing**: every Ask/Chat/RAG request shows which node served it (local or remote) -- Ask questions, share knowledge, send messages, coordinate emergency response — all offline -- No cloud account, no API key, no monthly bill — hardware you already own +A Raspberry Pi in a community center. ---- +An unused workstation in a local business. -## Features +Together, they become a shared AI cooperative. -### Agent Mode (ReAct tool calling) -Flip the **Agent mode** toggle in the Ask tab and the model stops being a chatbot and starts being an **agent**: it plans, calls real mesh tools over several steps, reads the results, and only then answers. Every step is shown live — **Thought → Tool → Observation → Answer**. +No centralized server required. -The agent's tools are bound to **real capabilities already on the bus** (no mock handlers): -`search_corpus` (RAG), `list_corpora`, `translate`, `list_marketplace`, `route_expert` (MoE), and `identify_plant` (vision). The loop uses a JSON `action:` protocol that works even on **tiny models with no native function-calling** — so a 4B MiniCPM or Nemotron Mini can drive the same agent as a 49B reasoner.

-*Audit date: June 15, 2026* - ---- - -## CRITICAL — Fixed ✅ - -### SEC-1: NVIDIA API Key Exposed in Frontend HTML - -**Severity:** Critical -**Status:** Fixed in commit (June 15, 2026) - -**What happened:** -`app_nemotron.py` and `hearthnet/ui/tabs/nemotron.py` both passed the live API key -as the `value=` parameter of a `gr.Textbox` component: - -```python -# VULNERABLE (before fix) -api_key_box = gr.Textbox( - label="🔑 NVIDIA API Key", - value=_NVIDIA_KEY, # ← actual secret sent to browser - type="password", - ... -) -``` - -Gradio serializes all component initial values into the page's JavaScript state -(`window.__gradio_state__` / WebSocket init message). Even though the field is -rendered as `type="password"` (dots in the UI), the underlying value is present in: -- The page source (`view-source:`) -- The Network tab → WS frames or the initial `/info` response -- `document.querySelector('[data-testid=...]').value` in the Console tab - -**How to reproduce (before fix):** -1. Open the Nemotron Space in Chrome -2. Open DevTools → Network tab -3. Reload page; inspect the first Gradio WebSocket frame or `/__/info` response -4. Search for `nvapi-` — the full key appears in plaintext - -**Fix applied:** -```python -# SAFE (after fix) -api_key_box = gr.Textbox( - label="🔑 NVIDIA API Key", - value="", # ← always empty; key stays server-side - type="password", - placeholder="nvapi-... leave blank if NVIDIA_API_KEY env var is set", -) -``` - -The server-side handlers already fall back to the env var: -```python -key = api_key.strip() or _NVIDIA_KEY # env var used if textbox is empty -``` -So if `NVIDIA_API_KEY` is set as a Space secret, users never need to type it. - -**Files changed:** -- `app_nemotron.py:288` — `value=_NVIDIA_KEY` → `value=""` -- `hearthnet/ui/tabs/nemotron.py:100` — `value=api_key_env` → `value=""` - ---- - -## MEDIUM — Action Required - -### SEC-2: API Key Typed by User Travels as Plaintext in POST Body - -**Severity:** Medium -**Status:** Mitigated by HTTPS, not yet end-to-end encrypted - -If a user manually types an API key into the textbox (e.g. when running locally -over HTTP), the key is sent in the Gradio WebSocket message body when the button -is clicked. On HF Spaces this is HTTPS so the transport is encrypted. On local -HTTP it is not. - -**Recommendation:** -For local deployments, document that the API key textbox is for development only. -For production, always use `NVIDIA_API_KEY` env var (Space secret) and leave -the textbox empty. Add a warning label when the Space is detected as HTTP: - -```python -is_https = os.getenv("SPACE_HOST", "").startswith("https") -if not is_https: - gr.Markdown("⚠ Running over HTTP — use env var, not the key textbox") -``` - -### SEC-3: Rate Limiting Not Enforced on Capability Bus Endpoints - -**Severity:** Medium -**Status:** Open — `RateLimiter` class implemented but not wired - -`hearthnet/bus/backpressure.py` contains a working `RateLimiter(max_calls, window_seconds)`. -The FastAPI routes at `/bus/v1/call`, `/relay/v1/join`, `/relay/v1/send` are publicly -accessible with no rate limiting. A malicious client can: -- Exhaust ZeroGPU quota by spamming `llm.chat` calls -- Flood the relay hub roster with fake node registrations - -**How to fix:** -```python -# In app.py, _mount_bus_endpoints(): -from hearthnet.bus.backpressure import RateLimiter - -_limiter = RateLimiter(max_calls=60, window_seconds=60) - -@app.middleware("http") -async def _rate_limit_middleware(request, call_next): - client_ip = request.client.host if request.client else "unknown" - if request.url.path.startswith(("/bus/v1", "/relay/v1")): - if not _limiter.allow(client_ip): - from fastapi.responses import JSONResponse - return JSONResponse({"error": "rate_limited"}, status_code=429) - return await call_next(request) -``` - -### SEC-4: Capability Token Expiry Not Enforced - -**Severity:** Medium -**Status:** Open — `exp` field stored but never checked - -M16 capability tokens (`hearthnet/tokens/`) store an `exp` (expiry) timestamp -in the JWT-like structure, but the router (`hearthnet/bus/router.py`) never -validates it before routing a call. An expired token continues to work indefinitely. - -**How to fix:** -```python -# In hearthnet/bus/router.py, before routing: -import time -token_exp = getattr(token, "exp", None) -if token_exp and time.time() > token_exp: - raise PermissionError("capability token expired") -``` - -### SEC-5: `trust_remote_code=True` in Florence2 Backend - -**Severity:** Medium -**Status:** Partially mitigated — allowlist added (June 12 security audit) - -`hearthnet/services/image/backends/florence2.py` loads the Florence2 model with -`trust_remote_code=True`. The allowlist restricts which model IDs are permitted, -but if a mesh peer can influence `MODEL_ID` via a capability call, arbitrary code -execution is possible. - -**Recommendation:** -Pin the Florence2 model to a known-good hash in `pyproject.toml` or hardcode -the model ID rather than reading it from a bus payload. - ---- - -## LOW — Informational - -### SEC-6: Mesh Node URL Visible in Frontend - -**Severity:** Low -**Status:** Acceptable — not a secret - -`app_nemotron.py:421` passes `value=_MESH_NODE` to a visible (non-password) -textbox. `HEARTHNET_NODE` is a public Space URL, not a credential.

I’m requesting escalation for read-only inspection now; without that, I can’t see the project or the hackathon instructions. -> -> The workspace folder is empty, so the “import project” step is literal: I need to clone the Space repo here before the agents can read docs or split the work. I’ll bring the Space into this workspace next. -> -> The Space is cloned. I’m reading the docs and project layout now, then I’ll write the coordination files and split implementation work into non-overlapping pieces. -> -> The repo is currently docs plus two HTML prototypes, which is useful: Phase 1 can become a polished, deployable browser-first Space rather than a backend-heavy import. I’m sending parallel agents to summarize the phase docs, assess the current prototypes, and identify HF deployment requirements while I start the task/agent scaffolding locally. -> -> The docs confirm Phase 1 is the “make the architecture legible and demoable” slice: identity, discovery, capability bus, local services, emergency mode, UI/onboarding. I’m going to make a static Space that demonstrates that system cleanly, plus Python quality scaffolding so the requested tools have real targets. -> -> I’ve got enough structure to split the work cleanly. I’ll keep coordination/docs local, and delegate three disjoint write scopes: Python core/demo model, Space UI/static assets, and quality/test configuration. -> -> Before touching code, I’m adding the coordination files the request called for: `tasks.md` for the Phase 1 work breakdown and `agents.md` for who owns which surface.

I’m checking the first agent returns now; after that I’ll either integrate their patches or fill any gaps directly if a slice needs tightening. -> -> One deployment read suggests flipping to a static Space, but the repo metadata and docs both point at Gradio, and your lint/type/security request benefits from real Python. I’m staying with `sdk: gradio` and making `app.py` real rather than downgrading to static. -> -> The read-only agents line up: the strongest Phase 1 is a Gradio Space with a faithful simulated mesh plus the existing browser P2P prototype kept as advanced evidence. I’m waiting on the three write-scope workers now, then I’ll run the requested gates and push. -> -> The quality config landed first. I’ll inspect it with the other incoming changes once the core/UI workers finish so I can tune everything against the actual files instead of configuring in the abstract. -> -> All worker slices are back. I’m doing the integration pass now: check imports, align the UI with the core, update task statuses, and then run the full lint/security/type/test sequence. -> -> The integration review found a few polish issues already: `requirements.txt` asks for Gradio `<6` while README pins `6.16.0`, and `app.py` has some rough encoding/typing/stdlib-import details. I’m going to tighten those before running the gates. -> -> The core is coherent enough for Phase 1: bus, registry, router, discovery, emergency detector, services, controller/facades. I’m applying a small integration patch now: align Gradio versions, remove mojibake from app output, replace dynamic math import, expose clean core hooks to the UI, and mark the task checklist accurately. -> -> The first patch missed one encoded bullet exactly, so nothing was applied. I’m splitting the patch into smaller, safer edits and leaving the tricky rendered text as a broader line replacement. -> ->

I’m applying formatter output and continuing with security/type/static analysis. -> -> Bandit only flagged demo-only jitter randomness, mypy found a few loose dictionary types, and the pylint command got mangled by PowerShell variable parsing.

I’m going to make `tasks.md` say that plainly module by module, with completed demo items separated from missing production work. -> -> The current `tasks.md` is too binary: it marks the demo slice done, but doesn’t show that most modules are still “demo/stub/missing” relative to the full docs. I’m replacing it with a coverage matrix so nobody mistakes Phase 1 proof-of-shape for full spec completion. -> -> First audit result confirms the uncomfortable but useful truth: M08 is demo, M09/M10 are stubs, M11-M13 are missing. I’m folding that into `tasks.md` and waiting for the lower-level/cross-cutting audits so the matrix covers the whole spec. -> -> All three audits agree: yes, the implementation follows the controller/facade/bus pattern and demonstrates the Phase 1 flow, but no, it does not fully implement every M01-M13/X01-X04 requirement.

The app will retrieve local context, then try a real local Transformers model on ZeroGPU; only if the route is explicitly online and `OPENAI_API_KEY` exists will it use OpenAI. If a selected local model is too large or unavailable, the UI will report the real backend error instead of fabricating a response. -> -> I’ll keep the existing spec matrix you asked for, but mark the new correction: “no mocks” applies now to AI responses.

Discovery - -HearthNet uses **three discovery methods** (in priority order): - -### mDNS (LAN — automatic) - -Every node announces itself as `_hearthnet._tcp.local.` using **Zeroconf**. -No configuration needed. Works on any LAN where mDNS is not blocked. - -``` -Node A starts → announces _hearthnet._tcp.local. via mDNS -Node B starts → discovers Node A, sees its capabilities, registers them on its bus -``` - -### UDP multicast (LAN — fallback) - -Uses multicast group `239.255.42.42:42424`. -Works when mDNS is blocked by a firewall or managed switch. - -### Relay tier (WAN — Phase 2) - -For nodes behind NAT or across the internet, configure a relay URL: - -```toml -[discovery] -relay_urls = ["https://your-relay.example.com"] -``` - -See [docs/p2_p3/M15-relay-tier.md](../p2_p3/M15-relay-tier.md). - -### Checking connected peers - -**In the UI:** Settings tab → "Connected Peers & Capabilities" → click Refresh. - -**Via CLI:** -```bash -python -m hearthnet.cli status -python -m hearthnet.cli caps --remote-only -``` - ---- - -## 4. Multi-Device / Multi-Browser - -### Two browsers on the same LAN - -1. Start HearthNet on one machine with `host = "0.0.0.0"` in `config.toml` -2. Open `http://:7860` in any browser on the LAN - -Both browsers connect to the **same node** — they share the same bus, peer list, and capabilities. - -### Two separate nodes (two machines) - -1. Machine A: `python -m hearthnet.cli run` -2. Machine B: `python -m hearthnet.cli run` -3. Both must be on the same LAN (mDNS) or share a relay URL - -Once discovered, Machine B's bus sees Machine A's capabilities (e.g. `llm.chat@1.0`). -Calls made from Machine B's UI automatically route to whichever node has the best-scoring provider. - -### Testing two clients in one browser (different tabs / incognito) - -Each browser tab that opens the Gradio UI is just a view onto the same node. -To simulate two truly independent clients, run two nodes on different ports: - -```bash -# Terminal 1 -HEARTHNET_TRANSPORT_PORT=7081 HEARTHNET_UI_PORT=7861 python -m hearthnet.cli run - -# Terminal 2 -HEARTHNET_TRANSPORT_PORT=7082 HEARTHNET_UI_PORT=7862 python -m hearthnet.cli run -``` - -Open `http://127.0.0.1:7861` and `http://127.0.0.1:7862` in two browser tabs. -Both nodes discover each other via mDNS within a few seconds. - -### Playwright E2E test for two nodes - -```python -# tests/test_e2e_playwright.py already includes: -# - TestUiLoads — all 6 tabs present -# - TestAskTab — real LLM/fallback response -# - TestResponsiveLayout — mobile viewport -``` - -Run: -```bash -python -m pytest tests/test_e2e_playwright.py -v -``` - ---- - -## 5. RAG — Adding to the Knowledge Base - -### Via the UI (Settings tab → RAG — Ingest Documents) - -1. Open the Settings tab -2. Expand "RAG — Ingest Documents" -3. Enter a corpus name (default: `community`) -4. Upload a `.txt`, `.md`, or `.pdf` file -5. Click **Ingest** - -The document is chunked (1000 tokens, 200-token overlap), embedded, and stored in ChromaDB. - -### Via CLI - -```bash -python -m hearthnet.cli rag ingest ./docs/emergency-procedures.md --corpus community -python -m hearthnet.cli rag ingest ./manuals/first-aid.pdf --corpus medical - -# List corpora -python -m hearthnet.cli rag list -``` - -### Via the bus (programmatic) - -```python -result = await bus.call( - "rag.ingest", (1, 0), - {"input": { - "corpus": "community", - "doc_title": "Emergency procedures", - "text": "... full document text ...", - }} -) -``` - -### Using RAG in the Ask tab - -Select a corpus from the dropdown in the Ask tab. HearthNet retrieves -the top-k most relevant chunks and provides them as context to the LLM. - ---- - -## 6. LLM Backends - -HearthNet tries backends in this order: - -| Priority | Backend | When to use | -|----------|---------|-------------| -| 1 | **Ollama** | Best UX. Zero-config. `ollama serve` + `ollama pull ` | -| 2 | **llama.cpp HTTP** | Direct GPU control. Start with `./server -m model.gguf` | -| 3 | **OpenBMB / MiniCPM** | Small local models (4–8B). Pi-friendly | -| 4 | **Nemotron** | NVIDIA cloud or NIM server | -| 5 | **Generic OpenAI-compat** | LM Studio, vLLM, any OpenAI-compatible server | -| 6 | **HF Transformers** | Last resort local inference | - -Cloud APIs (OpenAI, Nemotron cloud) are **never the default** — they require explicit config and are automatically deregistered when the node goes offline. - -### Ollama - -```bash -# Install: https://ollama.com -ollama pull llama3.2:3b # 2 GB — works on 4 GB RAM -ollama pull qwen2.5:7b # 5 GB — good quality -ollama pull minicpm3:4b # 3 GB — Pi-friendly -``` - -```toml -[[llm.backends]] -name = "ollama" -url = "http://localhost:11434" -``` - -### llama.cpp HTTP server (recommended) - -```bash -./server -m models/qwen2.5-7b-q4_k_m.gguf --port 8080 -c 4096 -``` - -```toml -[[llm.backends]] -name = "llama_cpp" -url = "http://localhost:8080" -model = "qwen2.5-7b" -``` - -### OpenBMB MiniCPM (via vLLM) - -```bash -vllm serve openbmb/MiniCPM4-8B --port 8000 -``` - -```toml -[[llm.backends]] -name = "openbmb" -url = "http://localhost:8000" -model = "openbmb/MiniCPM4-8B" -``` - -### Nemotron (cloud or NIM) - -```bash -export NVIDIA_API_KEY=nvapi-xxx -``` - -```toml -[[llm.backends]] -name = "nemotron" -url = "https://integrate.api.nvidia.com/v1" -model = "nvidia/nemotron-mini-4b-instruct" -api_key_env = "NVIDIA_API_KEY" -``` - ---- - -## 7. Creating and Managing a Community - -A **community** is a signed group manifest with member trust levels. - -### Create a new community - -```bash -python -m hearthnet.cli init --name "My Neighborhood" --profile anchor -``` - -This: -1. Generates Ed25519 keys in `~/.hearthnet/keys/` -2. Creates a community manifest signed by the root key -3. Writes `~/.hearthnet/config.toml` - -### Join an existing community - -```bash -python -m hearthnet.cli invite redeem "hnvite://v1/..." -``` - -### Check community status - -```bash -python -m hearthnet.cli status -``` - ---- - -## 8. Inviting Other Nodes - -### Generate an invite link (UI) - -Settings tab → "Invite a Node" → enter trust level → click **Generate Invite Link**. - -### Generate an invite link (CLI) - -```bash -python -m hearthnet.cli invite create --node-id ed25519:xxx --level member -# Prints: hnvite://v1/... -``` - -### Redeem on the new node - -```bash -python -m hearthnet.cli invite redeem "hnvite://v1/..." -``` - -### Mobile (M22) - -The mobile app (Flutter) can scan a QR code displayed by: - -```bash -python -m hearthnet.cli invite create --qr -``` - -Or via the Settings tab → Invite a Node → the link can be pasted into the app's -"Join Community" screen. - ---- - -## 9. Extending HearthNet - -### Adding a new capability (service) - -1. Create `hearthnet/services/myservice/service.py` - -```python -# Spec reference: docs/M03-bus.md §4 (Service Protocol) -from hearthnet.services.base import Service -from hearthnet.bus.capability import CapabilityDescriptor, RouteRequest - -class MyService(Service): - name = "myservice" - version = "1.0" - - def capabilities(self): - desc = CapabilityDescriptor( - name="myservice.do@1.0", - version=(1, 0), - stability="beta", - request_schema={}, - response_schema=None, - stream_schema=None, - params={}, - max_concurrent=4, - trust_required="member", - timeout_seconds=30, - idempotent=True, - ) - return [(desc, self.handle_do, None)] - - async def handle_do(self, req: RouteRequest) -> dict: - inp = req.body.get("input", {}) - return {"output": {"result": f"processed: {inp}"}, "meta": {}} - - async def start(self): pass - async def stop(self): pass - def health(self): return {"status": "ok"} -``` - -2. Register with the bus in `hearthnet/node.py`: - -```python -from hearthnet.services.myservice.service import MyService -bus.register_service(MyService()) -``` - -3. Add tests in `tests/test_myservice.py`. - -### Adding a new LLM backend - -Implement `LlmBackend` (Protocol in `hearthnet/services/llm/backends/base.py`): - -```python -# Spec: docs/M04-llm.md §3.1 -class MyLlmBackend: - name = "myllm" - models = [BackendModel(name="my-model", family="local", context_length=8192, requires_internet=False)] - - async def chat(self, messages, *, model, stream=False, temperature=0.7, max_tokens=1024, **kw): - ... # call your server, return ChatResult or AsyncIterator[Token] - - async def complete(self, prompt, *, model, **kw): ... - async def warm(self): pass - async def close(self): pass - def health(self): return {"status": "ok"} -``` - -Then register it in `LlmService.__init__` alongside the other backends. - -### Adding a new UI tab - -1. Create `hearthnet/ui/tabs/mytab.py` - -```python -# Spec: docs/M08-ui.md §5 -def build_mytab(bus=None): - import gradio as gr - with gr.Column(): - gr.Markdown("### My Tab") - ... -``` - -2. Add it to `hearthnet/ui/app.py` inside the `gr.Tabs()` block: - -```python -with gr.Tab("MyTab"): - from hearthnet.ui.tabs.mytab import build_mytab - build_mytab(self._bus) -``` - ---- - -## 10. Troubleshooting - -### No LLM responses - -1. Check Ollama is running: `ollama list` -2. Check `python -m hearthnet.cli doctor` -3. Check `python -m hearthnet.cli caps` — does `llm.chat@1.0` appear? - -### Peers not discovered - -1. Are both machines on the same LAN subnet? -2. Is mDNS blocked? Try enabling UDP fallback in config -3. `python -m hearthnet.cli status` — what does it show? - -### RAG returns no results - -1. Did you ingest documents? Settings tab → RAG — Ingest Documents -2. `python -m hearthnet.cli rag list` — are corpora listed? -3. Embedding model must be loaded — check `python -m hearthnet.cli doctor` - -### Config file location - -``` -~/.hearthnet/config.toml (Linux/macOS) -%USERPROFILE%\.hearthnet\config.toml (Windows) -``` - -### Log files - -```bash -python -m hearthnet.cli log --follow -# Or look at: -~/.hearthnet/logs/hearthnet.log -``` - -### Emergency mode stuck "offline" - -```bash -# Force a connectivity check: -python -m hearthnet.cli call emergency.probe@1.0 '{}' -# Or in UI: Emergency tab → Run Connectivity Probe -``` - ---- - -## 11. How Routing Works - -**Spec:** [docs/modules/M03-bus.md](../modules/M03-bus.md) §3.5 / §5.4 -**Implementation:** `hearthnet/bus/router.py`, `hearthnet/bus/__init__.py` - -### The capability bus - -Every node has a `CapabilityBus`. Services register their capabilities on startup. -When another node or the UI calls `bus.call("llm.chat", (1, 0), body)`, the bus: - -1. **Route selection** — `Router.route(req)` scores all registered providers (local and remote) using the score formula below. -2. **Local-first** — local handlers always get priority over remote ones (lower latency, no serialization). -3. **Call dispatch** — if local: `await entry.handler(req)`; if remote: `await transport.call(node_id, req)`. -4. **Health update** — `HealthTracker.record(entry, success, latency_ms)` updates rolling success-rate and latency EMA. - -### Score formula - -``` -score = (1.0 if is_local else 0.5) - + success_rate * 0.3 - - (in_flight / max_concurrent) * 0.2 - + (1.0 if not quarantined else -999) -``` - -A quarantined entry (repeated failures) scores `-999` and is skipped until the cooldown expires. - -### Params-based routing - -When a capability descriptor is registered with **params** (e.g. `{"corpus": "medical", "requires_internet": False}`), the router also checks whether the caller's `body["params"]` are compatible: - -```python -def _corpus_matches(offered: dict, requested: dict) -> bool: - return requested.get("corpus", offered["corpus"]) == offered["corpus"] -``` - -This lets multiple nodes serve the same capability name with different parameters, and callers select the one that matches their requirements. - -### Sticky sessions (M10 Chat) - -Pass `session_id` to `bus.call(...)` to pin subsequent calls to the same node: - -```python -result = await bus.call("chat.history", (1, 0), body, session_id="s:abc123") -``` - -Subsequent calls with the same `session_id` route to the same entry (sticky routing). - -### Routing a call to a specific node - -Use the `InMemoryTransport` directly (in tests) or send an HTTP request to the transport server: - -``` -POST http://:7080/call -Content-Type: application/json - -{ - "capability": "llm.chat", - "version_req": [1, 0], - "body": {"input": {"messages": [{"role": "user", "content": "Hello"}]}} -} -``` - -### Offline/Emergency routing - -When `Detector.apply_probe_results({"internet": False})` marks the node offline: -- All capabilities with `requires_internet=True` are **deregistered** from the bus -- Calls that were routed to internet-only providers now fail over to local providers -- This is automatic — callers see no difference - ---- - -## 12. Creating a Special-Feature Node - -A **special-feature node** is any node where you register a non-default set of capabilities. - -### OCR-only node (medical document reading) - -```python -# hearthnet/examples/ocr_node.py -from hearthnet.node import HearthNode -from hearthnet.services.ocr.service import OcrService # M17 -from hearthnet.ui.app import build_ui - -node = HearthNode("ocr-node-01", "OCR Specialist", "ed25519:your-community") -node.bus.register_service(OcrService(backend="tesseract")) -# Do NOT install LLM or RAG services if this node should only do OCR - -ui = build_ui(bus=node.bus, display_name=node.display_name, node_id=node.node_id, community_id=node.community_id) -ui.build().launch(server_port=7865) -``` - -Any other node in the community can now call `ocr.extract@1.0` and the bus -automatically routes it to this specialist node. - -### Medical-RAG node (EBKH evidence base) - -```python -from hearthnet.services.demo import RagService -from hearthnet.services.llm.service import LlmService - -# Install LLM with a domain-specific system prompt -llm = LlmService(model="ollama:meditron-7b") -rag = RagService(corpus="medical-ebkh") - -node.bus.register_service(llm) -node.bus.register_service(rag) - -# Optionally seed the RAG corpus on startup -import asyncio -asyncio.run(node.rag.ingest("medical-ebkh", title="WHO First Aid", text="...")) -``` - -### Anchor node (high-availability, no UI) - -An **anchor** node (`profile="anchor"`) is designed for always-on servers or Pis: - -```bash -python -m hearthnet.cli run --profile anchor --no-ui -``` - -```toml -[identity] -profile = "anchor" - -[transport] -host = "0.0.0.0" -port = 7080 - -[ui] -enabled = false # anchor nodes typically don't serve a web UI -``` - -Anchor nodes act as relay points (M15) and capability hubs. Other nodes discover them and offload compute tasks. - -### Multilingual translation node (M18) - -```python -from hearthnet.services.translation.service import TranslationService - -node.bus.register_service( - TranslationService(backend="helsinki-nlp", languages=["de", "fr", "es", "ar"]) -) -``` - -Callers use `translation.translate@1.0` with `{"input": {"text": "...", "source": "en", "target": "de"}}`. - -### Civil Defense node (M31) — emergency broadcast - -```python -from hearthnet.services.civil_defense.service import CivilDefenseService - -node.bus.register_service( - CivilDefenseService( - broadcast_endpoints=["239.255.42.42:42425"], # UDP multicast - priority_filter="critical", - ) -) -``` - -### Combining capabilities (full-service node) - -```python -node.install_demo_services() # LLM, RAG, Marketplace, Chat - -# Then add specialist services on top: -node.bus.register_service(OcrService()) -node.bus.register_service(TranslationService()) -node.bus.register_service(SttTtsService()) -``` - -The bus merges all capabilities. Peer nodes discover all of them via the manifest exchange. - -### Verified capabilities in the UI - -The Settings tab → "Connected Peers & Capabilities" → Refresh shows the live list -of what each peer node offers. You can verify routing is correct before deploying. - diff --git a/docs/guides/fieldguide.md b/docs/guides/fieldguide.md deleted file mode 100644 index 4c33a6425a38934b26f19106a72fccbfcee188cc..0000000000000000000000000000000000000000 --- a/docs/guides/fieldguide.md +++ /dev/null @@ -1,694 +0,0 @@ -Build Small -the idea -tracks -## Build Small - -the idea -tracks -rules -prizes -find your kit -partners -submit -faq - -**Submit** -Hugging Face × Gradio -N 45.21 · W 122.6 - -## BUILD SMALL - -Build something small, local, and yours. - -Registration’s closed and the jam is underway — this is your field guide.

Notes on the trackio integration - -[Trackio](https://github.com/huggingface/trackio) is HuggingFace's local-first experiment tracker built on Gradio. Optional in HearthNet; enable by setting `config.observability.trackio_project`. - -Integration points: - -1. **Activated by config.** `TrackioExporter` is constructed only if `trackio_project` is set. Otherwise the class is unused; HearthNet runs Prometheus-only. - -2. **Bridged from TraceHook.** `M03 §3.6` `TraceHook.on_call_end` checks for an active exporter and forwards. No service code calls trackio directly. - -3. **Optional HF Spaces sync.** If `trackio_space` is set, runs mirror to the named Space — handy for sharing demo telemetry. Off by default; the demo on Christof's machine logs locally. - -4. **What gets logged.** Each LLM call is one step with: `latency_ms`, `tokens_in`, `tokens_out`, `model`, `backend`, `result`. Topology snapshots logged every 60s with mesh size, online state, capability counts. Marketplace post counts and chat throughput as gauges. - -5. **Why this fits HearthNet.** Trackio is local-first (matches HearthNet's ethos), Gradio-native (matches the existing UI stack), and gives Christof a dashboard he already knows how to extend without adding Prometheus + Grafana. - ---- - -## 24. Notes on the Nemotron and OpenBMB backends - -Both register exactly like existing backends: as `LlmBackend` implementations producing `BackendModel` entries that the service enumerates as `(backend, model)` capability instances. - -### `NemotronBackend` - -NVIDIA's Nemotron family (Llama-3.1-Nemotron-70B, Nemotron-mini, Nemotron-4-340B-instruct). Two modes: - -- **Cloud (default):** `https://integrate.api.nvidia.com/v1`, OpenAI-compatible. `requires_internet=True`. Free tier exists; bring an `NVIDIA_API_KEY`. M09 will deregister this backend automatically when offline. -- **Local (`local=True`):** point at a self-hosted NIM endpoint or vLLM-served Nemotron model. `requires_internet=False`. - -Models declared by `models: list[BackendModel]` at construction time. Use these typical entries: - -```python -BackendModel("nvidia/llama-3.1-nemotron-70b-instruct", quant="api", ctx_max=128000, modalities=["text"], requires_internet=True) -BackendModel("nvidia/nemotron-mini-4b-instruct", quant="api", ctx_max=4096, modalities=["text"], requires_internet=True) -``` - -### `OpenBmbBackend` - -OpenBMB's MiniCPM family — Christof's primary local-AI-workbench target. Typically served via vLLM, SGLang, or llama.cpp's HTTP server on `http://localhost:8000` (or wherever the workbench binds). OpenAI-compatible HTTP. `requires_internet=False` (always local). - -Models declared: - -```python -BackendModel("openbmb/MiniCPM4-8B", quant="fp16", ctx_max=32768, modalities=["text"], requires_internet=False) -BackendModel("openbmb/MiniCPM-V-2_6", quant="fp16", ctx_max=8192, modalities=["text","vision"], requires_internet=False) -``` - -Vision-capable MiniCPM-V variant is reserved for Phase 2 when [CONTRACT §12 open question 1](CAPABILITY_CONTRACT.md) lifts; vision messages stay text-only in MVP. - -### Config example - -```toml -[[llm.backends]] -name = "openbmb" -url = "http://localhost:8000" -model = "openbmb/MiniCPM4-8B" - -[[llm.backends]] -name = "nemotron" -url = "https://integrate.api.nvidia.com/v1" -model = "nvidia/llama-3.1-nemotron-70b-instruct" -api_key_env = "NVIDIA_API_KEY" - -[[llm.backends]] -name = "lmstudio" -url = "http://192.168.188.25:1234" -model = "qwen2.5-7b-instruct" -``` - -Three backends, four models if MiniCPM-V is later added → eight capability entries on the bus (two each for `llm.chat` and `llm.complete` × four models). The router picks among them at call time. - ---- - -## 25. Coherence guarantees enforced by this reference - -If you implement strictly against this document, the following hold automatically: - -- **No symbol name appears in two different modules** — see §18. -- **Every capability has exactly one handler** — see §19. -- **Every event type has at least one producer** — see §20. -- **Every constant is defined in `constants.py` and nowhere else** — see §0.2. -- **The 15-step orchestration produces a runnable node** — see §17 `node.py`. -- **Cross-references resolve** — every `M0N`/`X0N` link points at an existing spec; every spec section number used here exists. - -If you find a contradiction between this document and a spec, the spec wins by default — but file the discrepancy. The most common drift will be in field names of capability `params` (caught by the params predicate at registration time). - ---- - -## 26. What is intentionally NOT in this document - -- **Test code** — see the `tests/` section in each spec. Implement after the production code compiles. -- **Service-internal helpers** that are pure implementation detail (private functions inside one file with leading underscore). Add as you need them. -- **Phase 2/3 modules** — `federation.*`, `ocr.*`, `tts.*`, `stt.*`, `trans.*`, `img.*`, `chat.thread.*`, `chat.forward.*` are mentioned in specs but have no MVP symbols. -- **Vendor-specific tuning** — llama.cpp `n_threads`, vLLM tensor parallel, Nemotron prompt prefixes. Decide per backend at integration time. - ---- - -*End of HearthNet Implementation Reference.* -*Spec set version: v1.0 · this document touched: 2026-06-09.* \ No newline at end of file diff --git a/docs/roadmap.md b/docs/roadmap.md index ef9428a38811b647b0f7322f8ce3545521f0ae30..4582b6b6271b7829843794c98019d9167256db83 100644 --- a/docs/roadmap.md +++ b/docs/roadmap.md @@ -1,346 +1,306 @@ -# HearthNet Hackathon Master Plan - -**Timeline:** June 6 → June 15 -**Theme:** Community-owned resilient AI infrastructure - -## Team Structure - -| Role | Person | Responsibility | -| --- | --- | --- | -| Product Lead | Christof | Vision, architecture, scope | -| Tech Lead | TBD | Technical decisions | -| Backend Engineer | TBD | Capability Bus | -| AI Engineer | TBD | LLM & Routing | -| RAG Engineer | TBD | Knowledge system | -| Frontend Engineer | TBD | UI | -| DevOps Engineer | TBD | Deployment | -| Marketing Lead | TBD | Social, branding | -| Pitch Lead | TBD | Presentation | -| Community Manager | TBD | Discord, recruiting | - -## Overall Roadmap - -| Date | Product | Engineering | AI | DevOps | Marketing | Pitch | -| --- | --- | --- | --- | --- | --- | --- | -| Jun 6 | Team Formation | Repo Setup | Research | Infra Setup | Recruitment | Story Outline | -| Jun 7 | Architecture Freeze | Core Framework | Model Selection | Docker | Branding | Problem Statement | -| Jun 8 | MVP Scope | Discovery | LLM Node | CI/CD | First Post | Demo Flow | -| Jun 9 | Review | Routing | RAG | Containers | Screenshots | Narrative | -| Jun 10 | Scope Check | Integration | Retrieval | Deployments | Progress Post | Draft Slides | -| Jun 11 | Testing | Features | Optimization | Monitoring | Community Feedback | Pitch Draft | -| Jun 12 | Feature Freeze | Bug Fixes | Bug Fixes | Bug Fixes | Video Clips | Presentation | -| Jun 13 | Demo Review | Polish | Polish | Polish | Social Push | Demo Script | -| Jun 14 | Final Review | Final Fixes | Final Fixes | Final Fixes | Launch Post | Rehearsal | -| Jun 15 | Submission | Submission | Submission | Submission | Promotion | Presentation | - -## Product & Architecture Track - -### June 6 - -#### Deliverables - -- Confirm HearthNet concept -- Define MVP -- Define stretch goals -- Create architecture diagram -- Create user journey - -#### Questions to Answer - -- What problem are we solving?

Die Geschichte der Entwicklung des Computers an sich jedoch reicht zurück bis in die Antike und umfasst deutlich mehr, als nur die modernen Computertechnologien oder mechanischen bzw. elektrischen Hilfsmittel (Rechenmaschinen oder Hardware). Sie umfasst z. B. auch die Entwicklung von Zahlensystemen und Rechenmethoden, die etwa für einfache Schreibgeräte auf Papier und Tafeln entwickelt wurden. Im Folgenden wird versucht, einen Überblick über diese Entwicklungen zu geben. - -Zahlen und Ziffern als Grundlage der Computergeschichte -Das Konzept der Zahlen lässt sich auf keine konkreten Wurzeln zurückführen und hat sich wahrscheinlich mit den ersten Notwendigkeiten der Kommunikation zwischen zwei Individuen entwickelt. Man findet in allen bekannten Sprachen mindestens für die Zahlen eins und zwei Entsprechungen. - -Als Weiterentwicklung ist der Übergang von der reinen Anzahlbenennung zum Gebrauch mathematischer Rechenoperationen wie Addition, Subtraktion, Multiplikation und Division anzusehen; auch Quadratzahlen und Quadratwurzel sind hierunter zu fassen. Diese Operationen wurden formalisiert (in Formeln dargestellt) und dadurch überprüfbar. Daraus entwickelten sich dann weiterführende Betrachtungen, etwa die von Euklid entwickelte Darstellung des größten gemeinsamen Teilers. - -Im Mittelalter erreichte das ursprünglich aus Indien stammende arabische Zahlensystem Europa und erlaubte eine größere Systematisierung bei der Arbeit mit Zahlen. Es erlaubte die Darstellung von Zahlen, Ausdrücken und Formeln auf Papier und die Tabellierung von mathematischen Funktionen wie der Quadratwurzel, des einfachen Logarithmus und trigonometrischer Funktionen. Zur Zeit der Arbeiten von Isaac Newton war Papier und Velin eine bedeutende Ressource für Rechenaufgaben und ist dies bis in die heutige Zeit geblieben, in der Forscher wie Enrico Fermi seitenweise Papier mit mathematischen Berechnungen füllten und Richard Feynman jeden mathematischen Schritt mit der Hand bis zur Lösung berechnete, obwohl es zu seiner Zeit bereits programmierbare Rechner gab. - -Frühe Entwicklung von Rechenmaschinen und -hilfsmitteln - -Der Abakus -Das früheste Gerät, das in rudimentären Ansätzen mit einem heutigen Computer verglichen werden kann, ist der Abakus, eine mechanische Rechenhilfe, die vermutlich um 1100 v. Chr. im indochinesischen Kulturraum erfunden wurde. Der Abakus wurde bis ins 17. Jahrhundert benutzt und dann durch die ersten Rechenmaschinen ersetzt. In einigen Regionen der Welt wird der Abakus auch heute noch immer verwendet. Einem ähnlichen Zweck diente auch das Rechenbrett des Pythagoras. - - -Mechanismus von Antikythera -Bereits im 1. Jahrhundert v. Chr. wurde mit dem Räderwerk von Antikythera die erste Rechenmaschine erfunden.[1] Das Gerät diente vermutlich für astronomische Berechnungen und funktionierte mit einem Differentialgetriebe. - -Mit dem Untergang der Antike kam der technische Fortschritt in Mittel- und Westeuropa fast zum Stillstand und in den Zeiten der Völkerwanderung ging viel Wissen verloren (so beispielsweise auch das Räderwerk von Antikythera, das erst 1902 wiederentdeckt wurde) oder wurde nur noch im oströmischen Reichsteil bewahrt. Die muslimischen Eroberer der oströmischen Provinzen und schließlich Ost-Roms (Konstantinopel) nutzten dieses Wissen und entwickelten es weiter. Durch die Kreuzzüge und spätere Handelskontakte zwischen Abend- und Morgenland sowie die muslimische Herrschaft auf der iberischen Halbinsel, sickerte antikes Wissen und die darauf aufbauenden arabischen Erkenntnisse langsam wieder nach West- und Mitteleuropa ein. Ab der Neuzeit begann sich der Motor des technischen Fortschritts wieder langsam zu drehen und beschleunigte fortan – und dies tut er bis heute. - - -Der Rechenschieber, eine der wichtigsten mechanischen Rechenhilfen für die Multiplikation und Division -1614 publizierte John Napier seine Logarithmentafel. Mitentdecker der Logarithmen ist Jost Bürgi. 1623 baute Wilhelm Schickard die erste Vier-Spezies-Maschine mit getrennten Werken für Addition/Subtraktion und Multiplikation/Division und damit den ersten mechanischen Rechner, wodurch er zum „Vater der Computerära“ wurde. Seine Konstruktion basierte auf dem Zusammenspiel von Zahnrädern, die im Wesentlichen aus dem Bereich der Uhrmacherkunst stammten und dort genutzt wurden, wodurch seine Maschine den Namen „Rechenuhr“ erhielt. Ein weiteres Exemplar war für Johannes Keplers astronomische Berechnungen bestimmt, verbrannte aber halbfertig. Schickards eigenes Gerät ist verschollen. - -1642 folgte Blaise Pascal mit seiner Zweispezies-Rechenmaschine, der Pascaline. 1668 entwickelte Samuel Morland eine Rechenmaschine, die erstmals nicht dezimal addierte, sondern auf das englische Geldsystem abgestimmt war. 1673 baute Gottfried Wilhelm Leibniz seine erste Vierspezies-Maschine und erfand 1703 (erneut) das binäre Zahlensystem (Dualsystem), das später die Grundlage für die Digitalrechner und darauf aufbauend die digitale Revolution wurde. - - -Mechanischer Rechner von 1914 -1805 nutzte Joseph-Marie Jacquard Lochkarten, um Webstühle zu steuern. 1820 baute Charles Xavier Thomas de Colmar das „Arithmometer“, den ersten Rechner, der in Massenproduktion hergestellt wurde und somit den Computer für Großunternehmen erschwinglich machte. Charles Babbage entwickelte von 1820 bis 1822 die Differenzmaschine (englisch Difference Engine) und 1837 die Analytical Engine, konnte sie aber aus Geldmangel nicht bauen. 1843 bauten Edvard und George Scheutz in Stockholm den ersten mechanischen Computer nach den Ideen von Babbage. Im gleichen Jahr entwickelte Ada Lovelace eine Methode zur Programmierung von Computern nach dem Babbage-System und schrieb damit das erste Computerprogramm. 1890 wurde die US-Volkszählung mit Hilfe des Lochkartensystems von Herman Hollerith durchgeführt. 1912 baute Torres y Quevedo eine Schach­maschine, die mit König und Turm einen König matt setzen konnte, und somit den ersten Spielcomputer. - -Mechanische Rechner wie die darauf folgenden Addierer, der Comptometer, der Monroe-Kalkulator, die Curta und der Addo-X wurden bis in die 1970er Jahre genutzt. Diese Rechner nutzten alle das Dezimalsystem. Dies galt sowohl für die Rechner von Charles Babbage um 1800 wie auch für den ENIAC von 1945, den ersten vollelektronischen Universalrechner überhaupt. - -Es wurden jedoch auch nichtmechanische Rechner gebaut, wie der Wasserintegrator. - -Von 1935 über die Zuse Z1 bis zur Turing-Bombe -1935 stellten IBM die IBM 601 vor, eine Lochkartenmaschine, die eine Multiplikation pro Sekunde durchführen konnte. Es wurden ca. 1500 Exemplare verkauft. 1937 meldete Konrad Zuse zwei Patente an, die bereits alle Elemente der so genannten Von-Neumann-Architektur beschreiben. Im selben Jahr baute John Atanasoff zusammen mit dem Doktoranden Clifford Berry einen der ersten Digitalrechner, den Atanasoff-Berry-Computer, und Alan Turing publizierte einen Artikel, der die Turingmaschine, ein abstraktes Modell zur Definition des Algorithmusbegriffs, beschreibt. - -1938 stellte Konrad Zuse die Zuse Z1 fertig, einen frei programmierbaren mechanischen Rechner, der allerdings aufgrund von Problemen mit der Fertigungspräzision nie voll funktionstüchtig war. Die Z1 verfügte bereits über Gleitkommarechnung. Sie wurde im Krieg zerstört und später nach Originalplänen neu gefertigt, die Teile wurden auf modernen Fräs- und Drehbänken hergestellt. Dieser Nachbau der Z1, der im Deutschen Technikmuseum in Berlin steht, ist mechanisch voll funktionsfähig und hat eine Rechengeschwindigkeit von 1 Hz, vollzieht also eine Rechenoperation pro Sekunde. Ebenfalls 1938 publizierte Claude Shannon einen Artikel darüber, wie man symbolische Logik mit Relais implementieren kann. (Lit.: Shannon 1938) - -Während des Zweiten Weltkrieges gab Alan Turing die entscheidenden Hinweise zur Entzifferung der Enigma-Codes und baute dafür einen speziellen mechanischen Rechner, Turing-Bombe genannt. - -Entwicklung des modernen turingmächtigen Computers -Bis zum Ende des Zweiten Weltkrieges - -Nachbau der Zuse Z3 im Deutschen Museum in München -Ebenfalls im Krieg (1941) baute Konrad Zuse die erste funktionstüchtige programmgesteuerte binäre Rechenmaschine, bestehend aus einer großen Zahl von Relais, die Zuse Z3. Wie 1998 bewiesen werden konnte, war die Z3 turingmächtig und damit außerdem die erste Maschine, die – im Rahmen des verfügbaren Speicherplatzes – beliebige Algorithmen automatisch ausführen konnte. Aufgrund dieser Eigenschaften wird sie oft als erster funktionsfähiger Computer der Geschichte betrachtet.[2] Die nächsten Digitalrechner waren der in den USA gebaute Atanasoff-Berry-Computer (Inbetriebnahme 1941) und die britische Colossus (1941). Sie dienten speziellen Aufgaben und waren nicht turingmächtig. Auch Maschinen auf analoger Basis wurden entwickelt. - - -Colossus Mark II -Auf das Jahr 1943 wird auch die angeblich von IBM-Chef Thomas J. Watson stammende Aussage „Ich glaube, es gibt einen weltweiten Bedarf an vielleicht fünf Computern.“ datiert. Im selben Jahr stellte Tommy Flowers mit seinem Team in Bletchley Park den ersten „Colossus“ fertig. 1944 erfolgte die Fertigstellung des ASCC (Automatic Sequence Controlled Computer, „Mark I“ durch Howard H. Aiken) und das Team um Reinold Weber stellte eine Entschlüsselungsmaschine für das Verschlüsselungsgerät M-209 der US-Streitkräfte fertig.[3] Zuse hatte schließlich bis März 1945 seine am 21. Dezember 1943 bei einem Bombenangriff zerstörte Z3 durch die deutlich verbesserte Zuse Z4 ersetzt, den damals einzigen turingmächtigen Computer in Europa, der von 1950 bis 1955 als zentraler Rechner der ETH Zürich genutzt wurde. - - -Computermodell Land Inbetriebnahme Gleitkomma- -arithmetik Binär Elektronisch Programmierbar Turingmächtig -Zuse Z3 Deutschland Mai 1941 Ja Ja Nein Ja, mittels Lochstreifen über Umwege, nie genutzt -Atanasoff-Berry-Computer USA Sommer 1941 Nein Ja Ja Nein Nein -Colossus UK 1943 Nein Ja Ja Teilweise, durch Neu­ver­kabelung Nein -Mark I USA 1944 Nein Nein Nein Ja, mittels Lochstreifen Ja -Zuse Z4 Deutschland März 1945 Ja Ja Nein Ja, mittels Lochstreifen keine bedingte Sprunganweisung -um 1950 Ja Ja Nein Ja, mittels Lochstreifen Ja -ENIAC USA 1946 Nein Nein Ja Teilweise, durch Neu­ver­kabelung Ja -1948 Nein Nein Ja Ja, mittels Wider­stands­matrix Ja -Nachkriegszeit - -ENIAC auf einem Bild der US-Armee - -Der EDVAC - -Röhrenrechner Ural-1 aus der Sowjetunion -Das Ende des Zweiten Weltkriegs erlaubte es, dass Europäer und Amerikaner von ihren Fortschritten gegenseitig wieder Kenntnis erlangten. Im Jahr 1946 wurde der Electronical Numerical Integrator and Computer (ENIAC) unter der Leitung von John Eckert und John Mauchly entwickelt und an der Moore School of Electrical Engineering der Universität von Pennsylvania gebaut. Der ENIAC verfügte über 20 elektronische Register, 3 Funktionstafeln als Festspeicher und bestand aus 18.000 Röhren sowie 1.500 Relais.[4] Der ENIAC ist der erste vollelektronische digitale Universalrechner (Konrad Zuses Z3 verwendete 1941 noch Relais, war also nicht vollelektronisch). 1947 baute IBM den Selective Sequence Electronic Calculator (SSEC), einen Hybridcomputer mit Röhren und mechanischen Relais und die Association for Computing Machinery (ACM) wurde als erste wissenschaftliche Gesellschaft für Informatik gegründet. Im gleichen Jahr wurde auch der erste Transistor realisiert, der heute aus der modernen Technik nicht mehr weggedacht werden kann. Die maßgeblich an der Erfindung beteiligten William B. Shockley, John Bardeen und Walter Brattain erhielten 1956 den Nobelpreis für Physik. In die späten 1940er Jahre fällt auch der Bau des Electronic Discrete Variable Automatic Computer (EDVAC), der erstmals die Von-Neumann-Architektur implementierte. - -Im Jahr 1949 stellte Edmund C. Berkeley, Begründer der ACM, mit „Simon“ den ersten digitalen, programmierbaren Computer für den Heimgebrauch vor. Er bestand aus 50 Relais und wurde in Gestalt von Bauplänen vertrieben, von denen in den ersten zehn Jahren ihrer Verfügbarkeit über 400 Exemplare verkauft wurden. Im selben Jahr stellte Maurice Wilkes mit seinem Team in Cambridge den Electronic Delay Storage Automatic Calculator (EDSAC) vor; basierend auf John von Neumanns EDVAC ist es der erste Rechner, der vollständig speicherprogrammierbar war. Ebenfalls 1949 besichtigte der Schweizer Mathematikprofessor Eduard Stiefel die in einem Pferdestall in Hopferau aufgestellte Zuse Z4 und finanzierte die gründliche Überholung der Maschine durch die Zuse KG, bevor sie an die ETH Zürich ausgeliefert wurde und dort in Betrieb ging.[5] - -1950er -In den 1950er Jahren setzte die Produktion kommerzieller (Serien-)Computer ein. Unter der Leitung von Alwin Walther wurde am Institut für Praktische Mathematik (IPM) der TH Darmstadt ab 1951 der DERA (Darmstädter Elektronischer Rechenautomat) erbaut. Remington Rand baute 1951 ihren ersten kommerziellen Röhrenrechner, den UNIVersal Automatic Computer I (UNIVAC I) und 1955 bei Bell Labs für die US Air Force nimmt der von Jean Howard Felker und L.C. Brown (Charlie Braun) gebaute TRansistorized Airborne DIgital Computer (TRADIC) den ersten Computer der Welt, der komplett mit Transistoren statt Röhren bestückt war den Betrieb auf; im gleichen Jahr begann Heinz Zemanek mit der Konstruktion des ersten auf europäischem Festland gebauten Transistorrechners, des Mailüfterls, das er 1958 der Öffentlichkeit vorstellte. - -Am 30. Dezember 1954[6] vollendet die DDR mit der „OPtik-REchen-MAschine“ (OPREMA) den Bau ihres ersten Computers mit Hilfe von Relais, der zunächst als Doppelrechner aus zwei identischen Systemen redundant ausgelegt wurde. Als klar war, dass die Maschinen stabil arbeiteten, wurden sie in zwei unabhängige Rechner getrennt. Programmierung und Zahleneingabe wurden per Stecktafel vorgenommen, die Ausgabe erfolgte über eine Schreibmaschine.[7] 1956 tauchte der Begriff „Computer“ erstmals in der DDR-Presse auf, nämlich im Zusammenhang mit dem Eniac-„Rechenautomaten“, dessen Akronym für „Electronic Numerical Integrator and Computer“ stand.[8][9] Geläufig wurde der Begriff erst Mitte der 1960er Jahre. - -1956 nahm die ETH Zürich ihre ERMETH in Betrieb und IBM fertigte das erste Magnetplattensystem (Random Access Method of Accounting and Control (RAMAC)). Ab 1958 wurde die Electrologica X1 als volltransistorisierter Serienrechner gebaut. Noch im selben Jahr stellte die Polnische Akademie der Wissenschaften in Zusammenarbeit mit dem Laboratorium für mathematische Apparate unter der Leitung von Romuald Marczynski den ersten polnischen Digital Computer „XYZ“ vor. Vorgesehenes Einsatzgebiet war die Nuklearforschung. 1959 begann Siemens mit der Auslieferung des Siemens 2002, ihres ersten in Serie gefertigten und vollständig auf Basis von Transistoren hergestellten Computers. - -1960er -1960 baute IBM den IBM 1401, einen transistorisierten Rechner mit Magnetbandsystem, und DECs (Digital Equipment Corporation) erster Minicomputer, die PDP-1 (Programmierbarer Datenprozessor) erscheint. 1962 lieferte die Telefunken AG die ersten TR 4 aus. 1964 baute DEC den Minicomputer PDP-8 für unter 20.000 Dollar. - -1964 definierte IBM die erste Computerarchitektur S/360, womit Rechner verschiedener Leistungsklassen denselben Code ausführen konnten und bei Texas Instruments wurde der erste „integrierte Schaltkreis“ (IC) entwickelt. 1965 stellte das Moskauer Institut für Präzisionsmechanik und Computertechnologie unter der Leitung seines Chefentwicklers Sergej Lebedjew mit dem BESM-6 den ersten exportfähigen Großcomputer der UdSSR vor. BESM-6 wurde ab 1967 mit Betriebssystem und Compiler ausgeliefert und bis 1987 gebaut. 1966 erschien dann auch noch mit D4a ein 33-Bit-Auftischrechner der TU Dresden. - - -Olivetti Programma 101 -Der erste frei programmierbare Tischrechner der Welt, der „Programma 101“ von der Firma Olivetti,[10] erschien 1965 für einen Preis von $3,200[11] (was auf das Jahr 2017 bezogen $24,746[12] entspricht). - - -Nixdorf 820 von 1968 -1968 bewarb Hewlett-Packard (HP) den HP-9100A in der Science-Ausgabe vom 4. Oktober 1968 als „personal computer“, obgleich diese Bezeichnung nichts mit dem zu tun hat, was seit Mitte der 1970er Jahre bis heute unter einem Personal Computer verstanden wird. Die 1968 entstandene Nixdorf Computer AG erschloss zunächst in Deutschland und Europa, später auch in Nordamerika, einen neuen Computermarkt: die Mittlere Datentechnik bzw. die dezentrale elektronische Datenverarbeitung. Massenhersteller wie IBM setzten weiterhin auf Großrechner und zentralisierte Datenverarbeitung, wobei Großrechner für kleine und mittlere Unternehmen schlicht zu teuer waren und die Großhersteller den Markt der Mittleren Datentechnik nicht bedienen konnten. Nixdorf stieß in diese Marktnische mit dem modular aufgebauten Nixdorf 820 vor, brachte dadurch den Computer direkt an den Arbeitsplatz und ermöglichte kleinen und mittleren Betrieben die Nutzung der elektronischen Datenverarbeitung zu einem erschwinglichen Preis. Im Dezember 1968 stellten Douglas C. Engelbart und William English vom Stanford Research Institute (SRI) die erste Computermaus vor, mangels sinnvoller Einsatzmöglichkeit (es gab noch keine grafischen Benutzeroberflächen) interessierte dies jedoch kaum jemanden. 1969 werden die ersten Computer per Internet verbunden. - -1970er -Mit der Erfindung des serienmäßig produzierbaren Mikroprozessors wurden die Computer immer kleiner, leistungsfähiger und preisgünstiger. Doch noch wurde das Potential der Computer verkannt. So sagte noch 1977 Ken Olson, Präsident und Gründer von DEC: „Es gibt keinen Grund, warum jemand einen Computer zu Hause haben wollte.“ - - -Intel 8008, Vorläufer des Intel 8080 -Im Jahr 1971 war es der Hersteller Intel, der mit dem 4004 den ersten in Serie gefertigten Mikroprozessor baute. Er bestand aus 2250 Transistoren. 1971 lieferte Telefunken den TR 440 an das Deutsche Rechenzentrum Darmstadt sowie an die Universitäten Bochum und München. 1972 ging der Illiac IV, ein Supercomputer mit Array-Prozessoren, in Betrieb. 1973 erschien mit Xerox Alto der erste Computer mit Maus, graphischer Benutzeroberfläche (GUI) und eingebauter Ethernet-Karte; und die französische Firma R2E begann mit der Auslieferung des Micral. 1974 stellte HP mit dem HP-65 den ersten programmierbaren Taschenrechner vor und Motorola baute den 6800-Prozessor, währenddessen Intel den 8080-Prozessor fertigte. 1975 begann MITS mit der Auslieferung des Altair 8800. 1975 stellte IBM mit der IBM 5100 den ersten tragbaren Computer vor. Eine Zeichenlänge von 8 Bit und die Einengung der (schon existierenden) Bezeichnung Byte auf dieses Maß wurden in dieser Zeit geläufig. - -1975 Maestro I (ursprünglich Programm-Entwicklungs-Terminal-System PET) von Softlab war weltweit die erste Integrierte Entwicklungsumgebung für Software. Maestro I wurde weltweit 22.000 Mal installiert, davon 6.000 Mal in der Bundesrepublik Deutschland. Maestro I war in den 1970er und 1980er Jahren führend auf diesem Gebiet. - - -Zilog Z80 -1976 entwickelte Zilog den Z80-Prozessor und Apple Computer stellte den Apple I vor, den weltweit ersten Personal Computer,[13][14][15] gefolgt 1977 vom Commodore PET und dem Tandy TRS-80. Der ebenfalls im Jahr 1977 veröffentlichte Apple II gilt bislang als letzter in Serie hergestellter Computer, der von einer einzelnen Person, Steve Wozniak, entworfen wurde.[16] 1978 erschien die VAX-11/780 von DEC, eine Maschine speziell für virtuelle Speicheradressierung. Im gleichen Jahr stellte Intel den 8086 vor, ein 16-Bit-Mikroprozessor; er ist der Urvater der noch heute gebräuchlichen x86-Prozessor-Familie. 1979 schließlich startete Atari den Verkauf seiner Rechnermodelle 400 und 800. Revolutionär war bei diesen, dass mehrere ASIC-Chips den Hauptprozessor entlasteten. - -1980er - -C64 mit 5¼″-Diskette und Laufwerk -Die 1980er waren die Blütezeit der Heimcomputer, zunächst mit 8-Bit-Mikroprozessoren und einem Arbeitsspeicher bis 64 KiB (Commodore VC20, C64, Sinclair ZX80/81, Sinclair ZX Spectrum, Schneider/Amstrad CPC 464/664, Atari XL/XE-Reihe), später auch leistungsfähigere Modelle mit 16-Bit- (Texas Instruments TI-99/4A) oder 16/32-Bit-Mikroprozessoren (z. B. Amiga, Atari ST). Eine Eigenentwicklung von Siemens, der Siemens PC 16-10, war dagegen mit einem Anfangspreis von 11.300 DM deutlich zu teuer. - -Das Unternehmen IBM stellte 1981 den IBM-PC vor, legte die Grundkonstruktion offen und schuf einen informellen Industriestandard;[17] sie definierten damit die bis heute aktuelle Geräteklasse der „IBM-PC-kompatiblen Computer“. Dank zahlreicher preiswerter Nachbauten und Fortführungen wurde diese Geräteklasse zu einer der erfolgreichsten Plattformen für den Personal Computer; die heute marktüblichen PCs mit Windows-Betriebssystem und x86-Prozessoren beruhen auf der stetigen Weiterentwicklung des damaligen Entwurfs von IBM. - -1982 brachte Intel den 80286-Prozessor auf den Markt und Sun Microsystems entwickelte die Sun-1 Workstation. Nach dem ersten Büro-Computer mit Maus, Lisa, der 1983 auf den Markt kam, wurde 1984 der Apple Macintosh gebaut und setzte neue Maßstäbe für Benutzerfreundlichkeit. Die Sowjetunion konterte mit ihrem „Kronos 1“, einer Bastelarbeit des Rechenzentrums in Akademgorodok. Im Januar 1985 stellte Atari den ST-Computer auf der Consumer Electronics Show (CES) in Las Vegas vor. Im Juli produzierte Commodore den ersten Amiga-Heimcomputer. In Sibirien wurde der „Kronos 2“ vorgestellt, der dann als „Kronos 2.6“ für vier Jahre in Serie ging. 1986 brachte Intel den 80386-Prozessor auf den Markt, 1989 den 80486. Ebenfalls 1986 präsentierte Motorola den 68030-Prozessor. Im gleichen Jahr stellte Acorn den ARM2-Prozessor fertig und setzte ihn im Folgejahr in Acorn-Archimedes-Rechnern ein. 1988 stellte NeXT mit Steve Jobs, Mitgründer von Apple, den gleichnamigen Computer vor. - -Die Computer-Fernvernetzung, deutsch „DFÜ“ (Datenfernübertragung), über das Usenet wurde an Universitäten und in diversen Firmen immer stärker benutzt. Auch Privatleute strebten nun eine Vernetzung ihrer Computer an; Mitte der 1980er Jahre entstanden Mailboxnetze, zusätzlich zum FidoNet das Z-Netz und das MausNet. - -1990er - -Pentium -Die 1990er sind das Jahrzehnt des Internets und des World Wide Web. (Siehe auch Geschichte des Internets, Chronologie des Internets) 1991 spezifizierte das AIM-Konsortium (Apple, IBM, Motorola) die PowerPC-Plattform. 1992 stellte DEC die ersten Systeme mit dem 64-Bit-Alpha-Prozessor vor. 1993 brachte Intel den Pentium-Prozessor auf den Markt, 1995 den Pentium Pro. 1994 stellte Leonard Adleman mit dem TT-100 den ersten Prototyp eines DNA-Computers vor, im Jahr darauf Be Incorporated die BeBox. 1999 baute Intel den Supercomputer ASCI Red mit 9.472 Prozessoren und AMD stellte mit dem Athlon den Nachfolger der K6-Prozessorfamilie vor. - -Entwicklung im 21. Jahrhundert -Zu Beginn des 21. Jahrhunderts sind Computer sowohl in beruflichen wie privaten Bereichen allgegenwärtig und allgemein akzeptiert. Während die Leistungsfähigkeit in klassischen Anwendungsbereichen weiter gesteigert wird, werden digitale Rechner unter anderem in die Telekommunikation und Bildbearbeitung integriert. 2001 baute IBM den Supercomputer ASCI White, und 2002 ging der NEC Earth Simulator in Betrieb. 2003 lieferte Apple den PowerMac G5 aus, den ersten Computer mit 64-Bit-Prozessoren für den Massenmarkt. AMD zog mit dem Opteron und dem Athlon 64 nach. - -2005 produzierten AMD und Intel erste Dual-Core-Prozessoren, 2006 doppelte Intel mit den ersten Core-2-Quad-Prozessoren nach – AMD konnte erst 2007 erste Vierkernprozessoren vorstellen. Bis zum Jahr 2010 stellten mehrere Firmen auch Sechs- und Achtkernprozessoren vor. Entwicklungen wie Mehrkernprozessoren, Berechnung auf Grafikprozessoren (GPGPU) sowie der breite Einsatz von Tablet-Computern dominieren in den letzten Jahren (Stand 2012) das Geschehen. - -Seit den 1980er Jahren stiegen die Taktfrequenzen von anfangs wenigen MHz bis zuletzt (Stand 2015) etwa 4 GHz. In den letzten Jahren konnte der Takt nur noch wenig gesteigert werden, stattdessen wurden Steigerungen der Rechenleistung eher durch mehr Prozessorkerne und vergrößerte Busbreiten erzielt. Auch wenn durch Übertaktung einzelne Prozessoren auf über 8 GHz betrieben werden konnten, sind diese Taktraten auch 2015 noch nicht in Serienprozessoren verfügbar. Außerdem werden zunehmend auch die in Computern verbauten Grafikprozessoren zur Erhöhung der Rechenleistung für spezielle Aufgaben genutzt (z. B. per OpenCL, siehe auch Streamprozessor und GPGPU). - -Seit ca. 2005 spielen auch Umweltaspekte (wie z. B. Stromsparfunktionen von Prozessor und Chipsatz, verringerter Einsatz schädlicher Stoffe) – bei der Produktion, Beschaffung und Nutzung von Computern zunehmend eine Rolle (siehe auch Green IT). - -2020 -Ende September 2020 wurde Europas letztes Computerwerk, Fujitsu in Augsburg, geschlossen.[18] - -Siehe auch -Commons: Geschichte des Computers – Sammlung von Bildern, Videos und Audiodateien -Elektronikschrott -Liste historischer Rechenanlagen in Europa -Liste von Computermuseen -Mediengeschichte -Technikgeschichte -Überwachung -Literatur -Edmund Callis Berkeley: Giant Brains or Machines That Think. 7.

The local node exposes `discovery.peer.add@1.0` (added in `hearthnet/discovery/service.py`). -2. `discovery.peer.add` fetches the Space's `/manifest`, registers all remote - capabilities into the local bus registry, and records the HTTPS endpoint. -3. When a capability (e.g. `llm.chat`) is only available remotely, the bus router - picks the remote peer and `HttpBusTransport` (`hearthnet/bus/http_transport.py`) - POSTs to the Space's `/bus/v1/call`. -4. The Space serves `/bus/v1/call`, `/manifest`, `/health`, and - `/bus/v1/capabilities` via FastAPI routes mounted into the Gradio app - (`_mount_bus_endpoints` in `app.py`). - -## Notes / limitations - -- **Sharing works:** `llm.chat`, `llm.complete`, `rag.query`, `rag.list_corpora`, - `rag.federated_query`, chat, market, file, evidence, civdef, OCR, translation, - STT/TTS, and image capabilities are all routable cross-network. -- **`embed.text` on the Space:** fails over the raw bus route with a ZeroGPU CUDA - error. GPU ops on HF ZeroGPU only run inside Gradio's `@spaces.GPU` event path, - not from a plain FastAPI route. This is an HF runtime constraint, not a bus bug; - embeddings work locally and on dedicated/CPU Spaces. -- **`invite redeem` / QR codes** are a separate *community-membership* flow - (`community.redeem`), not transport peering. Transport peering between nodes is - done via `discovery.peer.add` as shown here. diff --git a/docs/screenshots/_mesh_story.html b/docs/screenshots/_mesh_story.html deleted file mode 100644 index 72fc6c4955bd97cbb78e38a8afeb317040ab42af..0000000000000000000000000000000000000000 --- a/docs/screenshots/_mesh_story.html +++ /dev/null @@ -1,20 +0,0 @@ - -
