[Other] Show HN: StripeMeter – Open-Source Usage Metering for Stripe Billing We built StripeMeter, an open-source usage metering platform that plugs directly into Stripe. It solves the classic SaaS pain of “why is my bill higher than expected?” by giving both developers and customers real-time usage tracking with live cost projections. Why it matters:<p>- Transparency: Customers see exactly what Stripe will bill them (within 0.5% parity).<p>- Exactly-once guarantee: No double billing, ever.<p>- Fast &amp; scalable: Sub-minute freshness with Redis + Postgres counters.<p>We’d love feedback from SaaS builders, especially if you’ve struggled with Stripe’s metered billing. Does this solve a real pain for you? What would you need before trusting it in production?

[Other] Show HN: Fine-tuned Llama 3.2 3B to match 70B models for local transcripts I wrote a small local tool to transcribe audio notes (Whisper&#x2F;Parakeet). Code: <a href="https:&#x2F;&#x2F;github.com&#x2F;bilawalriaz&#x2F;lazy-notes" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bilawalriaz&#x2F;lazy-notes</a><p>I wanted to process raw transcripts locally without OpenRouter. Llama 3.2 3B with a prompt was decent but incomplete, so I tried SFT. I fine-tuned Llama 3.2 3B to clean&#x2F;analyze dictation and emit structured JSON (title, tags, entities, dates, actions).<p>Data: 13 real memos → Kimi K2 gold JSON → ~40k synthetic + gold; keys canonicalized. Chutes.ai (5k req&#x2F;day).<p>Training: RTX 4090 24GB, ~4h, LoRA (r=128, α=128, dropout=0.05), max seq 2048, bs=16, lr=5e-5, cosine, Unsloth. On 2070 Super 8GB it was ~8h.<p>Inference: merged to GGUF, Q4_K_M (llama.cpp), runs in LM Studio.<p>Evals (100-sample, scored by GLM 4.5 FP8): overall 5.35 (base 3B) → 8.55 (fine-tuned); completeness 4.12 → 7.62; factual 5.24 → 8.57.<p>Head-to-head (10 samples): ~8.40 vs Hermes-70B 8.18, Mistral-Small-24B 7.90, Gemma-3-12B 7.76, Qwen3-14B 7.62. Teacher Kimi K2 ~8.82.<p>Why: task specialization + JSON canonicalization reduces variance; the model learns the exact structure&#x2F;fields.<p>Lessons: train on completions only; synthetic is fine for narrow tasks; Llama is straightforward to train. Dataset pipeline + training script + evals: <a href="https:&#x2F;&#x2F;github.com&#x2F;bilawalriaz&#x2F;local-notes-transcribe-llm" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;bilawalriaz&#x2F;local-notes-transcribe-llm</a>
