How Chinas strategic focus on 3D printing and patent incentives since 2020 created a "minefield".
I gave all my Apple wealth away because wealth and power are not what I live for. I have a lot of fun and happiness. I funded a lot of important museums and arts groups in San Jose, the city of my birth, and they named a street after me for being good. I now speak publicly and have risen to the top....

On July 3, 2025, NASA astronaut Nichole Ayers captured a rare gigantic jet from the ISS—lightning shooting from a storm top into the upper atmosphere.
Sometimes software takes a long time to compile just due to how much code it has, like in the LLVM project. But often a build is slower than it could be for dumb, fixable reasons. I’ve had the suspicion that most builds are doing dumb stuff, but I had no way to see it. So I’ve been working on a cross-platform tool to help visualize builds, and you can try it!
本文主要围绕“隐私保护年龄验证”方案的可行性展开批判性分析,指出该方案在技术和社会层面均存在根本性缺陷,本质上是政客要求技术人员去实现一个不可能的目标。
Bellovin的分析揭示了实现所谓“隐私保护”年龄验证面临的多重不可逾越的障碍:
初始身份验证难题:
用户使用场景挑战:
经济与可行性问题:
复杂的治理与监管困境:
Ghostty 是一个跨平台终端模拟器,在 Linux 和 BSD 上彻底重写了其 GTK 应用,全面拥抱了 GObject 类型系统,并使用 Valgrind 进行了严格验证,从而提升了功能丰富度、稳定性和可维护性。
此前,Ghostty 的 GTK 应用刻意避免了 GObject 类型系统,这导致 Zig 管理的内存与 GTK 引用计数管理的内存生命周期难以同步,产生了一类反复出现的 bug:一方内存已释放而另一方未释放。避免使用 GObject 也阻碍了利用 GTK 的信号、属性、动作等原生功能。
重写后,应用全面集成了 GObject。例如,将 Zig 的 Config 结构包装进一个引用计数的 GhosttyConfig GObject。配置重载时,通过更新属性并利用 GObject 的属性变更通知系统,让配置更新自动、安全地传播至整个应用(甚至跨事件循环周期),旧配置在无引用时自动释放,概念上大大简化。此外,集成 GObject 后能够更方便地创建自定义 GTK 小部件,并采用了 Blueprint 等现代 UI 技术,从而更轻松地引入了如 GTK 标题栏标签页、响铃动画边框等新功能。
项目从第一个 PR 到最后一个 PR,均使用 Valgrind 检查了所有变更,确保无内存泄漏、未定义内存访问等问题。尽管运行 Valgrind 检查 GTK 应用需要一份大型抑制文件(大部分来自 GTK 自身、第三方库及 GPU 驱动),但这帮助发现了诸多潜在缺陷。
关键发现:
此次重写是 Ghostty 项目第五次对图形界面部分进行大规模重构,团队从每次迭代中积累了宝贵经验。全面集成 GObject 和持续的 Valgrind 验证,解决了此前架构中的核心痛点,带来了更健壮、功能更丰富的 Linux/BSD 版本。重写后的 GTK 应用已成为默认开发版本,并将包含在即将到来的 1.2 版本中。
The willingness of those in power to act fairly depends on how easily others can collectively push back against unfair treatment, psychologists have found.
According to a court exhibit, Sig Sauer identified several deadly risks with its P320 pistols as early as 2017.

The U.K. Online Safety Act was (avowedly, as revealed in a recent High Court case) “not primarily aimed at protecting children” but at regulating “services that have a significant influence over public discourse.”

HS2 has become a case study in how not to build infrastructure. But what if we’d taken a different path entirely? In this post, I imagine how the Swiss would have done it: starting with the timetable, not the project. It’s a counterfactual, but it’s not a fantasy.
