Sep 0.10.0 was released April 22nd, 2025 with optimizations for AVX-512 capable CPUs like the AMD 9950X (Zen 5) and updated benchmarks including the 9950X. Sep now achieves a staggering 21 GB/s on the 9950X for the low-level CSV parsing. 🚀 Before 0.10.0, Sep achieved ~18 GB/s on 9950X.
Cardinal Robert F. Prevost, the Chicago-born prefect of the Dicastery for Bishops under Pope Francis, was elected the 267th pope May 8 and took the name Pope Leo XIV.

Starlink is a low Earth orbit (LEO) satellite internet service provided by SpaceX. Users connect to near-Earth orbit satellites through a user terminal, which then connects to the internet via ground gateways.
As the new generation of satellites gradually incorporates laser links, some satellites can communicate with each other via laser. This both reduces reliance on ground stations and improves transmission efficiency, enhancing global coverage.

Aberdeen 是一个基于 TypeScript 的轻量级响应式 UI 库。它通过 ES6 Proxy 对象包装状态以实现精细的属性访问追踪,随后仅重新执行依赖于已更改数据的 DOM 构建闭包。这种方式无需虚拟 DOM 差异比较或编译器魔法,即可实现精确的 DOM 更新。
库中提供了多个示例,如:
其他示例包括输入演示、井字游戏、列表操作和路由。
Aberdeen 包含一个 skill/ 目录,可为 Claude Code、GitHub Copilot 等支持技能的 AI 代理提供专门的库使用知识。建议通过符号链接将其整合到项目的 .claude/skills 目录中。

A Formal Analysis of Apple's iMessage PQ3 Protocol 论文摘要
本文对Apple的iMessage PQ3设备间消息协议进行了详尽的形式化分析与机器验证。PQ3是一个高性能协议,为对抗具备量子计算能力的强敌提供强大安全保障。其核心设计采用混合方法,结合经典椭圆曲线迪菲-赫尔曼(ECDH)和后量子ML-KEM密码学原语,并将后量子安全的密钥封装机制(KEM)集成到初始设置阶段以及类似Signal的双棘轮结构中,从而提供了比仅在设置阶段使用后量子KEM的Signal协议更强的后折衷安全性。
核心贡献与发现:
协议概述: PQ3的通信始于通过Apple的ID服务(IDS)目录获取对方预公钥材料。会话建立时,使用ECDH和ML-KEM预公钥派生初始根密钥和链密钥。随后的通信采用双棘轮:
威胁模型与形式化建模: 分析假设存在强大的活跃网络对手,可以读取、拦截、重放和发送消息。对手默认可访问所有密钥材料,除非安全引理明确禁止。模型特别纳入了对手在未来获得量子计算机的场景,届时所有非后量子安全的原语(如ECDH)将被破解。在TAMARIN中,协议被建模为一组状态转换规则,并使用自定义的等式理论来模拟混合密钥派生函数(HKDF)、KEM封装等密码学操作。
安全证明与挑战: 证明的关键在于构建一系列辅助引理,以应对TAMARIN在证明涉及嵌套循环的协议时遇到的挑战:
通过这些引理,TAMARIN得以成功证明核心机密性和认证属性。例如,机密性引理表明,除非对手在特定条件下妥协了某个特定密钥(如消息密钥、相关链密钥、身份密钥或用于派生最新共享密钥的ECDH/KEM密钥),否则无法得知任何消息内容。这精确刻画了各种妥协场景下的安全边界。
结论与未来工作: 本文通过形式化验证为PQ3的高安全设计提供了强保证,并贡献了处理复杂协议证明的新方法论。未来的工作可延伸至分析PQ3与具体会话处理层(如iMessage的实现)结合后的安全性,以及密钥滚动等运行时行为。

The 18th century misadventures of HMS Wager and her reluctant crew
For decades, Americans were covering their bodies with more and more tattoos. Now, they’re getting them removed as fast as they can. We speak with the patients going under the laser, the tattoo-removal technicians whose business is booming, and the tattoo artists whose work is being erased to understand how something so permanent became so ephemeral.
