Show HN: Nv – workspace orchestrator for jj built for parallel agent workflowshttps://github.com/eersnington/jj-navihowdy y'all,i've been deep in jj for a while and been experimenting with jj workspaces for parallel workflows. it's more intuitive than git worktrees but it still has a couple of gotchas that have been a hindrance to my ideal workflow.so I built jj-navi - a tiny rust based cli that makes jj workspace orchestration a lot less pain in the ass.key bits: - `navi switch ` -> creates/switchs workspaces and cds into them automatically (via shell integration) - `navi list` -> shows insertions/deletions across workspaces and also runs jj snapshot (so you don't see stale work)check it out here at: https://github.com/eersnington/jj-navi (note: url at the top is a git.new one)also, this is heavily inspired by worktrunk (still my daily driver replacement for git worktrees) and jj-ryu by dillon mulroy from the orange cloud forking company.would love y'alls feedback, especially from heavy jj + agent users. feel free to open up issues on gh or hit me up on X.Apr 29, 2026 9:47 PM

Show HN: I built a 2nd-order PyTorch optimizer for LLMs that runs on 16GB GPUshttps://news.ycombinator.com/item?id=47947319Hi HN,I'm Danilo. I've been struggling with the limitations of AdamW when fine-tuning LLMs locally. Second-order optimizers (like Shampoo or SOAP) offer significantly better step-convergence by exploiting Kronecker-factored curvature. The problem? They require O(d^2) memory and O(d^3) compute per layer, which immediately OOMs consumer hardware like a 16GB T4 or RTX 3090.I wanted Shampoo-quality preconditioning on my home setup, so I built SCAO (Sparse Curvature-Aware Optimizer).It's a PyTorch optimizer that acts as a drop-in replacement for AdamW, but it implements a few strict architectural changes to survive on consumer cards:1. Adaptive Rank Selection: Instead of full-rank Kronecker factors, it truncates the eigenspace to retain >=95% of spectral mass. 2. Int8 EMA Quantization: The curvature accumulators are stored in symmetric int8, which yields a 4x memory reduction with zero degradation in perplexity. 3. Quantization Stability: Standard Shampoo usually crashes at step 1 during 4-Apr 29, 2026 12:19 PM
