neo

(to break out of algorithmic filter bubbles) and an Updater that chunks GraphQL queries to prevent 502 timeouts. The pipeline continuously updates a single `users.jsonl` file. *Privacy Note:* We use a "Stealth Star" architecture for opt-outs. If a dev stars our opt-out repo, the pipeline cryptographically verifies them, instantly purges their data, and blocklists them. No emails required. 2. *Engine-Level Streaming (O(1) Memory Parsing):* You can't `JSON.parse()` a 23MB JSONL file without freezing the UI. We built a Stream Proxy using `ReadableStream` and `TextDecoderStream` to parse the NDJSON incrementally, rendering the first 500 users instantly while the rest load in the background. 3. *Turbo Mode & Virtual Fields:* Instantiating 50k JS objects crushes memory. The store holds raw POJOs exactly as parsed. Complex calculated fields (like "Total Commits 2024") use prototype-based getters dynamically generated by a RecordFactory. Adding 60 new data columns adds 0 bytes of memory overhead per record. 4. *The "Fixed-DOM-Order" Grid:* We had to rewrite our underlying UI engine (Neo.mjs). Traditional VDOMs die on massive lists because scrolling triggers thousands of `insertBefore`/`removeChild` mutations. We implemented a strict DOM pool. The VDOM array length never changes. Rows leaving the viewport are recycled in place via hardware-accelerated CSS `translate3d`. A 60fps vertical scroll across 50,000 records generates 0 structural DOM mutations. 5. *Quintuple-Threaded Architecture:* To keep sorting fast and render "Living Sparklines" in the cells, we aggressively split the workload across workers. The Main Thread only applies DOM updates. The App Worker handles the 50k dataset, streaming, and VDOM generation. A dedicated Canvas Worker renders the sparklines independently at 60fps using `OffscreenCanvas`. The entire backend pipeline, streaming UI, and core engine rewrite were completed in one month by myself and my AI agent.

rable, will add more options on the way. Feedback appreciated! Thx & best regards, Tobias
