I'll be here for the next 5-6 hours. As usual, there are countless topics given the rapidly changing immigration landscape and I'll be guided by whatever you're concerned with. Please remember that I can't provide legal advice on specific cases because I won't have access to all the facts. Please stick to a factual discussion in your questions and I'll try to do the same in my answers.
Edit: I am taking a break now and will return later this afternoon/evening to respond to any comments and answer any questions. Thank you everyone for a great and engaged AMA so far.

Show HN: KVSplit – Run 2-3x longer contexts on Apple Silicon (🔥 Score: 150+ in 2 hours)
Link: https://readhacker.news/s/6uBAK
Comments: https://readhacker.news/c/6uBAK
I discovered that in LLM inference, keys and values in the KV cache have very different quantization sensitivities. Keys need higher precision than values to maintain quality.
I patched llama.cpp to enable different bit-widths for keys vs. values on Apple Silicon. The results are surprising:
- K8V4 (8-bit keys, 4-bit values): 59% memory reduction with only 0.86% perplexity loss
- K4V8 (4-bit keys, 8-bit values): 59% memory reduction but 6.06% perplexity loss
- The configurations use the same number of bits, but K8V4 is 7× better for quality
This means you can run LLMs with 2-3× longer context on the same Mac. Memory usage scales with sequence length, so savings compound as context grows.
Implementation was straightforward:
1. Added --kvq-key and --kvq-val flags to llama.cpp
2. Applied existing quantization logic separately to K and V tensors
3. Validated with perplexity metrics across context lengths
4. Used Metal for acceleration (with -mlong-calls flag to avoid vectorization issues)
Benchmarked on an M4 MacBook Pro running TinyLlama with 8K context windows. Compatible with Metal/MPS and optimized for Apple Silicon.

Comments: https://readhacker.news/c/6uABz
Hi There,
Erlang-RED has been my project for the last couple of months and I would love to get some feedback from the HN community.
The idea is to take advantage of Erlangs message passing and low overhead processes to have true concurrency in Node-RED flows. Plus also to bring low-code visual flow-based programming to Erlang.
