笔记，来自机房。
Raffael 白天构建自动化优先的平台和边缘系统，业余时间则在语言工具、本地优先应用、模拟和游戏上尝试各种想法。这里写的是平台自动化、边缘基础设施、应用安全，以及 AI 辅助的工程实践。编程语言和模型都只是工具。它们为人服务，而不是反过来。

Learning to Play
A chess prodigy's handbook, three old games and one laptop: rebuilding the ideas behind game-playing AI in Rust for a browser on my phone, and measuring them.

noteOpus 5.5 is the best Opus since 4.5
A month in, Claude Opus 5.5 feels like the next milestone after Opus 4.5: the same jump in what Claude Code can carry, now faster and cheaper per task.

reviewThe Web Was the Training Set
Tim Berners-Lee's memoir is the story of a British engineer at a Franco-Swiss lab giving a protocol away. Read in 2026, it is also the origin story of AI's data supply.

Observability Is Not Logging
A cost total says nothing about how a run went. This part turns each agent run into a trace: which turn escalated, which tool failed, where the money went.

This Site Is Becoming a Map
A blog shows what I wrote last. The new map on raskell.io shows what I keep coming back to, and it is the start of a public second brain.

The Bill Is Part of the Loop
Every model response already carries its own bill in the usage field, and the loop throws it away. This post reads that field, prices it against a table, and turns cost into a value the loop can see per turn and act on: a metering decorator that needs no loop change, a running ledger, prompt-cache accounting that moves the number the most, and a budget that degrades before it stops. Part eight of The Agent Platform Handbook.

The Model Is a Dependency
Every layer of the harness has existed to put the right tokens in front of one hardcoded model string. This post pulls that string out and makes the model a dependency: why you route a cheap model for easy turns and a strong one for hard turns, what a fallback looks like when a provider is down, and why 'models are commodities' is a claim about your architecture before it is a claim about the market. Part seven of The Agent Platform Handbook.

The Bottleneck Is Data, and Europe Is Sitting on It
Frontier AI is running short on public text, not compute. Europe's edge is the high-quality data it never put online. Capturing it needs coordination.

Archipelag.io 去中心化的 AI 算力：AI 任务运行在由社区运营的 GPU 主机网络上。任务优先选择就近的主机和首选地区，每个任务都会记录它在哪里运行；严格的地区约束正在开发中。目前为免费公开测试：主机在计量功能验证期间获得虚拟积分，真实货币结算尚未开放。

Cyanea 真正能重新运行的生物信息学笔记本。编写、运行并分享在浏览器中用 WebAssembly 执行的分析，无需安装任何东西。每个笔记本、数据集和输出都是一个可以再次运行的版本化快照。底层是 Rust 分析栈，内置 21 种文件格式。开源，自托管和联邦功能即将推出。
- 交付中
Arcanist 面向 AI 编写代码时代的 Haskell 工具。hx 是用 Rust 写的快速包与项目管理器，bhc 是一个尽可能检查一切的编译器。再加上一个记录哪些内容已被验证的注册中心，它们通向一个公共资源：无论是人还是模型，都不必把同一件事验证两次。
