GITHUB HUGGING FACE MODELSCOPE DISCORD Today, we’re announcing Qwen3-Coder, our most agentic code model to date. Qwen3-Coder is available in multiple sizes, but we’re excited to introduce its most powerful variant first: Qwen3-Coder-480B-A35B-Instruct — a 480B-parameter Mixture-of-Experts model with 35B active parameters which supports the context length of 256K tokens natively and 1M tokens with extrapolation methods, offering exceptional performance in both coding and agentic tasks. Qwen3-Coder-480B-A35B-Instruct sets new state-of-the-art results among open models on Agentic Coding, Agentic Browser-Use, and Agentic Tool-Use, comparable to Claude Sonnet 4.

有效的知识转移和工具设计应基于人类学习的三个核心原则:
当前AI工具的主流交互模式(如点击按钮即获答案、提供直接建议)存在严重问题:
AI应被设计为“健忘的指导员”或“采用苏格拉底式提问的橡皮鸭”,其目标是增强人类能力,而非替代人类思考。关键在于使用解释、演示、指导、增强的教学框架来设计交互:
解释:
演示:
指导:
增强:
以代码编写为例,不应直接要求AI生成代码。更好的方式是“逆向”使用AI:
AI在增强跨职能协作(如技术支持与开发团队之间)方面潜力巨大,但需要优先考虑内部效能改进。
结论:当前AI工具建设方式是本末倒置的。它用AI取代了人类最擅长的协作式累积学习,而AI本身并不擅长此道,导致了技能退化的恶性循环。解决方案是构建人类第一的工具,通过设计增强人类检索、过程学习和集体协作的能力,从而创建一个人类与工具相互促进的正向反馈循环。人类不仅是系统的一部分,人类就是核心。

For decades, Dennard scaling propelled remarkable advancements in processor technology. As transistor sizes shrank, manufacturers increased clock frequencies to enhance computational speed while simultaneously reducing power consumption, adhering to the principle of constant power density. This synergy delivered consistent performance improvements in both hardware and software. However, over the past two decades, this trend has faltered: physical and thermal constraints have caused clock frequencies to plateau, often leaving software performance stagnant as it struggles to fully utilize available hardware capabilities. Nevertheless, modern processors provide substantial opportunities for performance optimization through advanced architectural features. These include enhanced Single-Instruction-Multiple-Data (SIMD) instructions—such as Scalable Vector Extensions (SVE) and AVX-512—which enable parallel processing of large datasets, greater memory-level parallelism to improve data access efficiency, advanced branch predictors to enhance instruction flow, and broader superscalar execution to execute multiple instructions per cycle more effectively. We advocate for a comprehensive approach: robust mathematical models grounded in a current and detailed understanding of system architecture. Through this lens, we explore how algorithmic design can leverage these characteristics of contemporary processors, drawing insights from practical case studies in widely used software. Our findings underscore the critical need to align software design with hardware capabilities to overcome the challenges of the post-Dennard era.

This course covers elementary discrete mathematics for science and engineering, with a focus on mathematical tools and proof techniques useful in computer science. Topics include logical notation, sets, relations, elementary graph theory, state machines and invariants, induction and proofs by contradiction, recurrences, asymptotic notation, elementary analysis of algorithms, elementary number theory and cryptography, permutations and combinations, counting tools, and discrete probability.
In this article, I will describe a recent addition to CSS, the font-size-adjust property. I am also making a bold claim that everyone in the world misunderstands the usefulness of this property, including Google, MDN, and CSS Specification itself. (Just to clarify, no, I am not a web designer and I have no idea what I am talking about).

This is the second year I brought my Dad (a now-retired radio engineer and co-host of Geerling Engineering) to Open Sauce, a Bay Area maker faire-like event, dreamed up by William Osman and featuring hundreds of exhibits ranging from mad science, to vintage electronics, to games, to world-record-breaking Rubik's Cube solvers:
Sprawling over the grounds of the San Mateo County Event Center, I met people of all ages who were building all sorts of zany contraptions. Sometimes practical, sometimes wildly impractical (like a hot dog race track that tazes the winning weiner).

After watching this year’s EmacsConf and seeing Guile Emacs being resurrected I thought to myself - why limit ourselves to Guile? Sure, Guile isn’t just a Scheme implementation, thanks to its compiler-tower-based design. Other languages exist for Guile VM, such as Emacs Lisp, and Guile manual lists the following languages with various stages of completeness:
AI coding tools are dissolving the language barriers that once defined our careers. As someone who coded exclusively in Ruby for a decade, I’m now contributing to low-level system projects I couldn’t have touched before. Here’s how AI coding agents enabled my leap from Ruby to C, C++, and Rust.

# Brave 浏览器默认阻止微软 Recall 功能
Brave 浏览器从 Windows 版 1.81 版本起,默认阻止微软 Recall 功能自动截取用户浏览活动的屏幕截图。
## 背景与原因
- 微软在 2024 年 5 月宣布 Recall 功能,该功能每几秒全屏截图并存储在本地明文数据库中,存在安全风险,引发隐私担忧。
- 微软随后撤回该功能并进行调整。一年后 Recall 以预览形式回归,但其最终形态尚不确定。
- 基于 Brave 对隐私默认设置的重视,为保护用户浏览历史(尤其在家庭暴力等敏感场景中),Brave 主动在所有标签页中禁用 Recall。
## 实现方式
- Brave 利用微软提供的“隐私浏览窗口不被快照”的规则,将其扩展至所有 Brave 标签页。
- 通过告知操作系统所有标签页均为“私密”状态,从而阻止 Recall 的截取行为。
- 此举体现了 Brave 基于 Chromium 快速增强隐私功能的能力,且不影响正常截屏功能。
## 独特优势与对比
- Brave 是目前唯一默认在所有标签页禁用 Recall 的主要浏览器。
- 与 Signal 使用 DRM 标志禁用所有截屏不同,Brave 选择性禁用 Recall,允许辅助功能等正常截屏。
## 用户控制
- 用户可通过 `设置 > 隐私和安全` 路径,关闭“阻止 Microsoft Recall”选项来重新启用该功能。
## 相关隐私更新
- Brave 近期还推出了 Android 版的“Shred”按钮、优化了广告拦截引擎内存占用,以及 Android 版元素屏蔽功能等隐私增强特性。

本文介绍了如何创建Gzip炸弹,并探讨其在不同电子邮件客户端和代理中下载与解压时引发的行为,揭示了潜在的安全与稳定性问题。
dd if=/dev/zero bs=1G count=10 | gzip > 10gb.gz 生成一个10MB的Gzip文件,解压后可膨胀至约10GB。Content-Encoding: gzip 响应头。当客户端请求该文件时,会认为需要在线解压,从而在仅传输10MB网络数据后,客户端本地需处理10GB数据,可能造成资源耗尽。作者通过HTML邮件中的 <img> 标签引用上述Gzip炸弹文件,测试了不同环境的处理情况:

Tailwind的失败是CSS原有问题的放大镜
文章认为Tailwind并非创新解决方案,而是将CSS本身的缺陷与现代Web开发的弊病集中到了一个库中,带来了更差的开发体验。
CSS的现状:成功与遗留问题 CSS在近年发展迅速,Flexbox、Grid、Container Queries等现代特性极大地增强了响应式布局能力。其应用方式主要分两种:
!important。此外,CSS作为独立语言,与JavaScript的互操作性不足,导致常量等需要重复定义。Tailwind如何加剧了这些问题 Tailwind本质上是“通过类名实现的内联样式”,但它以一种更糟糕的方式放大了CSS的短板:
bg-blue text-lg)中,而非清晰的键值对,容易拼错且编辑器难以提供有效提示。!important 后缀(如 !text-red)。Tailwind流行的原因 尽管问题重重,Tailwind成功的原因在于:
结论与替代方案
作者认为Tailwind集各种缺点于大成。虽然它通过强制配置解决了风格一致性问题,但代价是更高的复杂度和更差的性能与体验。作者更推荐如 vanilla-extract 这类类型安全的CSS-in-JS方案,它们提供了更好的可维护性、类型检查和更小的运行时开销。核心观点是:并非存在“最佳”的全能方案,但Tailwind是“最差”的结合体。
