Quadtrees are everywhere spatial data exists. Mapping services use quadtree-like tile pyramids to serve map tiles at different zoom levels (Bing's quadkey system, for example, addresses tiles as base-4 paths). Game engines use them for collision detection and visibility culling. Geographic information systems use spatial indexes to store and query spatial datasets. PostGIS uses GiST indexes (R-tree-style) for spatial queries on geometries, while PostgreSQL's core supports quadtree-like SP-GiST indexes for certain data types like points.
I completely ignored Anthropic’s advice and wrote a more elaborate test prompt based on a use case I’m familiar with and therefore can audit the agent’s code quality. In 2021, I wrote a script to scrape YouTube video metadata from videos on a given channel using YouTube’s Data API, but the API is poorly and counterintuitively documented and my Python scripts aren’t great. I subscribe to the SiIvagunner YouTube account which, as a part of the channel’s gimmick (musical swaps with different melodies than the ones expected), posts hundreds of videos per month with nondescript thumbnails and titles, making it nonobvious which videos are the best other than the view counts. The video metadata could be used to surface good videos I missed, so I had a fun idea to test Opus 4.5:

For cable management, I used StarTech open-slot cable management raceway. There’s a Monoprice under-desk cable tray mounted below the top shelf of the desk. I found a 36” aluminum Tripp Lite twelve-outlet surge protector that happens to match the width of my desk perfectly. And, of course, the aluminum matches the aesthetic. It’s mounted to the back of the desk, with outlets facing down, toward the cable tray. I got a couple sheets of 1/8 inch plywood, finished them and added magnets. They attach to elevator bolts on the back of the desk. They cover the only areas where the cables would otherwise be exposed and are very easy to remove when I occasionally need to work with the cables.。业内人士推荐91视频作为进阶阅读
曾国藩的前辈老乡、大儒王船山的话更厉害——比如，为储粮备荒、平抑物价、赈灾救急等等，历代由朝廷或地方乃至乡绅出资建义仓、社仓，这是不是慈善？当然是。可是王船山反复批评这种义仓、社仓。为什么？因为它的作用有限而流弊益多，且以公义之名，蔽人眼力、阻人思想。正如当今由单位机构出钱组织义务写春联、送春联，固然是善事，但这种公益活动的流弊实在太大，同样以公义之名，蔽人眼力、阻人思想、消解人参与体验。，更多细节参见safew官方版本下载
