One of Germany's biggest ISPs changed how their DNS works, right after I exposed an organization that they’re part of.
It's not that hard to build a coding agent. 300 lines of code running in a loop with LLM tokens. You just keep throwing tokens at the loop, and then you've got yourself an agent.
Renewable power executives say difficulty getting permits, rising costs due to tariffs and the end of key tax credits are making it tough to plan.
In the past few years, CPUs have gotten really fast. Shockingly fast! Yet most people are stuck on previous generation mobile chips (whether by choice, or by their companies choice), at a huge detriment to their productivity. Meanwhile, AI coding subscriptions like Cursor are all the rage these days. I'll skip the debate on exactly how useful these tools are, and focus on the pricing. Cursor is $480/year for the team plan (the cheapest corporate plan), and other providers are around the same, setting a clear price point: engineering productivity is worth at least $500/year.
You’ve likely read lots of blog posts stating that it takes 23 minutes and 15 seconds to get back to work after an interruption, context switch, or meeting. Thus, “do you have five minutes” ends up not only costing those few minutes, but instead about half an hour. But where does that number come from?
I use my line scan camera to take cool pictures of trains and other stuff.
Toyota collected used high-voltage batteries from all kinds of cars to store the energy that powers Mazda's manufacturing HQ.
My latest love letter to Linux has been published. It's called Omarchy, and it's an opinionated setup of the Arch Linux distribution and the Hyprland tiling window manager. With everything configured out-of-the-box to give you exactly the same setup that I now run every day. My Platonic ideal of what a developer environment should look...

DeepWiki:快速理解任意代码库的工具
核心功能
DeepWiki 由 Cognition 开发,能将任何 GitHub 仓库即时转换为可导航的维基页面。通过将 GitHub 链接中的 github.com 替换为 deepwiki.com,即可生成该仓库的交互式文档,无需手动浏览文件或逐行阅读代码。
主要特性
deepwiki.com 网页端直接输入 GitHub 仓库 URL。主要应用场景
cursorrules.md 或 claude.md 等上下文摘要文件,供 AI 编码代理使用。github 替换为 deepwiki,可快速获取变更的结构化摘要,理解代码改动如何与整体代码库衔接,提升审查效率。总结与展望 作者认为 DeepWiki 是重新定位代码库、理解陌生部分、快速回归已遗忘组件或深入探索复杂开源项目的首选工具。他希望该工具未来能增加对话式助手模式(集成在 IDE 旁随时提问)和基于任务的入门指导(为目标提供分步实现路径)。
In the realm of computers, bugs are generally a bad thing. Every year, our team ships dozens of free updates to eliminate bugs that are an inescapable byproduct of the countless variables in software development. Rarely, though, a bug can be beneficial. Back in 2002, a software bug saved Rogue Amoeba. It started when we…

LLM models are plateauing, but true AGI isn't about scaling the next breakthrough model—it's about engineering the right context, memory, and workflow systems. AGI is fundamentally a systems engineering problem, not a model training problem.
The felt cap—one of only three surviving examples of its kind—was recently conserved by a museum in England
Celebrities like Taylor Swift have long used a little-known Federal Aviation Administration program to shield their private jets’ flight records from public view. Now ICE is using the program to hide information about its deportation flights.
这些法规共同构成了欧盟监管框架的核心,在保护公民权利、维护市场公平、应对全球挑战(如气候变化和数字化)方面发挥着关键作用。它们通常具有域外效力,对在欧盟运营或与欧盟有业务往来的全球企业产生重大影响。
SmallJS 是一种将 Smalltalk-80 编译到 JavaScript 的实现,采用基于文件的开发方式,而非传统的基于图像模式,允许用户在任何喜爱的 IDE 中进行开发。默认设置为 Visual Studio Code,支持 Smalltalk 语法着色和步骤调试功能,提升了开发体验。编码过程与 SmallJS 基础库(图像)分离,仅自动导入运行时所需的部分,优化了资源使用。
SmallJS 是完全面向对象的,可在各个层级进行自定义。为了增强易用性,Smalltalk 的类名和方法名大多与其 JavaScript 对应物保持一致,便于开发者快速适应。已封装在 Smalltalk 中的 JavaScript 库包括浏览器相关模块(如 Document、Window、HTML 元素、事件、CSS、流)和 Node.js 模块(如 HTTP 服务器、Express、4 种数据库、文件操作、多线程支持),覆盖了前端和后端开发的核心需求。
为了帮助用户快速上手,SmallJS 提供了多个示例项目。该语言面向新老开发者,旨在提供一种比 JavaScript 更优雅的选择,并支持逐步构建前端和后端应用。如需贡献或咨询,可通过邮件联系 info at small-js.org。

本文探讨了作者在Rust中寻找类似Go的Afero库的内存文件系统时遇到的挑战和测试结果。主要发现包括:
fstat和exec等系统调用导致的性能开销,从而提升测试速度。std::fs功能并支持内存文件系统,但会导致函数类型签名复杂化。vfs内存文件系统比std::fs快约850ms对1200ms,但后续深入测试发现差异可能源于链接器缓存或其他因素。hyperfine精确测试单个可执行文件时,vfs内存、rsfs内存、rsfs普通文件系统、std::fs ramdisk和普通SSD的测试时间均约为45ms,无明显差异。When I first started using Claude Code, I had a naive approach to working with it. I would describe the task directly in the prompt, press Enter, and cross my fingers. If the agent made mistakes, I would tell it how to fix them. For small tasks, this can be good enough, but as the task grows in complexity, this approach reveals several significant drawbacks. When Simple Doesn’t Scale The first problem is that the conversation becomes the only source of truth about the task.

In a service with capacity $\mu$ requests per second and background load $\lambda_0$, the usable headroom is $H = \mu - \lambda_0 > 0$. When $M$ clients align, e.g., after a cache expiry, at a cron boundary, or as a service returns from an outage, the bucketed arrival rate
