`PageIndex`: vectorless RAG with tree-based reasoning

Replaces embeddings and chunking with a document tree plus LLM-guided search. Interesting if vector recall keeps missing long-doc answers, but cost/latency need real-world validation.

[ KEY POINTS ]

Retrieval is split into two steps: build a table-of-contents-style tree, then run reasoning-based tree search over it.
The pitch is no vector DB and no chunking, with page/section references that make retrieval paths easier to inspect.
It claims 98.7% on FinanceBench, so the strongest fit is document-heavy domains where relevance beats semantic similarity.
Recent additions push it beyond a single file: file-system tree indexing, a chat product, and MCP/API access for agent workflows.

PapersWithCodeAI paper tracker — links code and benchmarks
The rebuilt site tracks trending papers, methods, citations, repos, artifacts, and benchmark results. Useful for model scouting, but still manually verified and early-stage.
- Default ranking uses GitHub star velocity, so it surfaces research projects gaining developer attention, not just citation-heavy papers.
- Coverage starts with high-impact items like Qwen 3.5, RF-DETR, DINOv3, MTEB, Open ASR Leaderboard, and coding-agent benchmarks.
- Paper pages auto-link GitHub repos, project URLs, artifacts, PDFs, and external non-Arxiv papers; multiple repos per paper are supported.
- Leaderboards exist by benchmark and domain, including MMTEB, COCO val 2017, and Terminal Bench; handy for fast model/vendor filtering.
- Result extraction uses AI agents, but verification is still manual. Treat it as a shortlist generator, not a source of record yet.

rkdebianDebian image build system — built for Doogee U10
A cheap locked-down device can become a bootable Debian 12 machine. Useful for low-cost Linux experiments, but the device scope is narrow and prerelease status keeps it niche.
- Targets the Rockchip RK3562-based Doogee U10; reuse value depends almost entirely on owning that exact hardware.
- Builds bootable Debian 12 Bookworm images, so the value is hardware repurposing more than a general dev-tool upgrade.
- Public prerelease build is dated May 14, 2026; treat it as an experiment box, not a dependable main workstation.

Stay Native Until Text Forces Your Hand

SwiftUI can handle Markdown chat UI until document-wide selection enters scope. Jumping to NSTextView brings TextKit 2 complexity and streaming CPU spikes, so delay it.
- SwiftUI gives acceptable baseline performance for Markdown chat, but full-document text selection is hard to support cleanly.
- Moving to NSTextView and TextKit 2 trades native UI simplicity for lower-level text control and more performance work.
- Streaming input can trigger CPU spikes in the text stack. Chat apps should benchmark incremental rendering before committing.
