谷歌 TPU 和英伟达 GPU 当前最大的差别在于：①谷歌目前仅支持到 FP8 领域，相对侧重于稳定性和大规模集群效率；②英伟达则更追求速度，在 Blackwell 系列中引入了 NVFP4 格式，从而推理性能在 FP8 的基础上再翻一倍。

Usually, about 20% of global oil and gas passes through the narrow shipping lane in the Gulf.
One of the key input vectors being exploited is the geofeed — a mechanism defined in RFC 8805. A geofeed is just a CSV file published by the address holder that says "this prefix is in this country, this region, this city." Geolocation providers like MaxMind, Cloudflare, and Google actively scrape these files and use them as a data source. The problem? There is essentially nothing to validate them. If you control a block of IP addresses — or lease one — you can publish a geofeed that claims those IPs are in Tokyo, São Paulo, or anywhere else you want. There's no verification against physical infrastructure, no cross-referencing with actual routing paths, nothing. You write a CSV, you host it, and the geolocation databases eat it up.
