** 德州仪器发布了 TI‑84 Evo，作为其经典图形计算器系列的最新版本，配备彩色 LCD、加速处理器和 USB‑C 接口，同时保持对原有 TI‑84 Plus 软件和配件的完全兼容。该产品针对高中和入门级大学的 STEM 课程，因考试规定和课堂使用习惯仍然高度依赖传统计算器。通过在不破坏生态的前提下升级硬件，TI 试图在平板电脑等新教学工具冲击下延长其平台的生命力。
**ARTICLE 2** **ENGLISH:** A recent study published in *Nature Neuroscience* suggests that participants can acquire new motor skills and even rehearse conversations while in REM sleep, provided sensory cues are paired with learning tasks before bedtime. Researchers used targeted memory reactivation with subtle sounds and found measurable performance gains the next day, indicating that sleep may be a viable window for skill consolidation and language practice. The findings could reshape educational strategies and open ethical debates about “sleep hacking” for productivity. **CHINESE:** 最近发表在《Nature Neuroscience》上的一项研究表明，参与者在 REM 睡眠期间，若在入睡前将特定感官线索与学习任务配对，便能在梦中练习新运动技能甚至对话。研究者通过轻微声音进行记忆再激活，第二天的表现出现显著提升，说明睡眠是技能巩固和语言练习的有效时机。这一发现可能改变教育方法，同时引发关于利用睡眠提升效率的伦理争论。
**ARTICLE 3** **ENGLISH:** The “smelly baby” investigation traces how disposable diapers, introduced in the 1960s, gained market dominance by outsourcing the unpleasant odor‑absorption function to super‑absorbent polymers (SAPs) and sophisticated sealing technologies. While SAPs dramatically improve leak protection, the article highlights the environmental toll of petro‑derived polymers, landfill accumulation, and the hidden health concerns from chemicals like sodium polyacrylate. Understanding this supply chain helps consumers evaluate the true cost of convenience versus sustainability. **CHINESE:** “臭宝宝”报道追溯了一次性尿布自 1960 年代起如何凭借超吸收聚合物（SAP）和先进封口技术将难闻的气味处理外包，从而占领市场。虽然 SAP 极大提升了防漏性能，文章却指出其石油基聚合物的环境代价、填埋堆积以及如聚丙烯酸钠等化学成分的潜在健康风险。了解这条供应链有助于消费者权衡便利与可持续性的真实成本。
**ARTICLE 4** **ENGLISH:** Wired profiles Eka, a startup that equipped a robotic gripper with a large‑language‑model (LLM) interface, allowing operators to describe desired manipulation tasks in natural language and have the robot infer the necessary grip forces and trajectories. The system bridges the “perception‑action gap” that has limited robot adaptability, demonstrating that LLMs can translate high‑level intent into low‑level motor commands. If generalized, this could accelerate the deployment of flexible automation in factories and logistics without extensive re‑programming. **CHINESE:** 《Wired》报道了 Eka 公司为机器人爪子加入大型语言模型（LLM）接口，使操作者可以用自然语言描述所需的操作任务，机器人随后推断出相应的抓握力度和轨迹。该系统弥合了长期限制机器人适应性的“感知‑行动鸿沟”，展示了 LLM 能将高级意图转化为低层运动指令。若能普遍应用，将大幅降低工厂和物流自动化的重新编程成本，加速柔性自动化的落地。
**ARTICLE 5** **ENGLISH:** The May 2026 “Ask HN: Who is hiring?” thread aggregates dozens of open positions across fintech, AI, and cloud infrastructure, with a noticeable rise in remote‑first roles and compensation packages that include equity in rapidly growing startups. Commenters note a continued talent shortage in Rust, Go, and security engineering, prompting companies to broaden seniority requirements and offer signing bonuses. The thread serves as a real‑time barometer of hiring trends and salary benchmarks for tech professionals navigating a tight labor market. **CHINESE:** 2026 年5月的 “Ask HN: Who is hiring?” 贴子汇总了金融科技、人工智能和云基础设施等领域的数十个招聘信息，明显看到远程优先岗位的增多以及快速增长的初创公司提供股权的薪酬套餐。评论者指出 Rust、Go 和安全工程师仍然供不应求，企业因此放宽对资历的要求并提供签约奖金。该贴子实时反映了招聘趋势和薪资基准，为在紧张人才市场中求职的技术人员提供了重要参考。
**ARTICLE 6** **ENGLISH:** Josh Comeau’s “Whimsical Animations” open‑house introduces a 6‑week intensive course that teaches modern CSS animation techniques, including keyframe design, Spring physics, and the new CSS Animation Worklet API. The curriculum emphasizes building reusable, performant animation libraries that can be dropped into React or vanilla projects, reflecting a growing demand for interactive UI experiences. Successful alumni report higher freelance rates and better job prospects, suggesting the market values specialized animation expertise. **CHINESE:** Josh Comeau 的 “Whimsical Animations” 公开课为期 6 周，教授现代 CSS 动画技巧，包括关键帧设计、弹簧物理以及全新的 CSS Animation Worklet API。课程注重构建可复用、高性能的动画库，可直接在 React 或原生项目中使用，呼应了对交互式 UI 体验日益增长的需求。毕业生普遍反映自由职业报酬提升、就业前景改善，表明市场对动画专才的价值认同度在上升。
**ARTICLE 7** **ENGLISH:** Microsoft’s **lib0xc** is a thin wrapper library that exposes a collection of C standard‑library‑adjacent APIs designed to reduce undefined behavior, buffer overflows, and other common security pitfalls in systems code. It provides safer alternatives for string handling, file I/O, and memory allocation while remaining ABI‑compatible with existing codebases, enabling incremental adoption. The project aims to raise the baseline security posture of low‑level software without sacrificing performance. **CHINESE:** 微软推出的 **lib0xc** 是一套围绕 C 标准库的安全封装 API，旨在降低系统代码中未定义行为、缓冲区溢出等常见安全漏洞。它提供更安全的字符串处理、文件 I/O 和内存分配函数，并保持与现有二进制接口兼容，便于逐步迁移。该项目的目标是在不牺牲性能的前提下提升底层软件的整体安全基准。
**ARTICLE 8** **ENGLISH:** **whohas** is a cross‑distribution command‑line utility that queries multiple Linux package repositories (APT, RPM, Pacman, etc.) to locate a given binary or library name, returning the exact package to install. By aggregating metadata from several distro APIs, it solves the common “I have a file but don’t know which package provides it” problem, saving developers time when working on heterogeneous environments. The tool is open‑source, MIT‑licensed, and already integrated into several DevOps scripts. **CHINESE:** **whohas** 是一款跨发行版的命令行工具，能够查询 APT、RPM、Pacman 等多个 Linux 包仓库，定位给定的二进制文件或库所属的具体软件包。它通过聚合各发行版的元数据，解决了 “已有文件却不清楚来源包” 的常见难题，帮助开发者在多平台环境中快速定位依赖。目前该工具已开源（MIT 许可证），并被多套 DevOps 脚本直接采用。
**ARTICLE 9** **ENGLISH:** Security researcher Metin Nextc demonstrates that the industry‑standard 16‑digit credit‑card number format is vulnerable to a high‑speed “partial‑knowledge” brute‑force attack when combined with predictable CVV‑generation algorithms used by some issuers. By exploiting timing side‑channels and using GPU clusters, the attacker can recover valid card numbers at a rate of several thousand attempts per second, raising concerns for merchants still relying on offline validation. The post urges faster adoption of tokenization and EMV‑Chip‑based authentication to mitigate the risk. **CHINESE:** 安全研究员 Metin Nextc 证实，标准的 16 位信用卡号在某些发行方使用可预测的 CVV 生成算法时，配合时间侧信道和 GPU 集群，可以进行高速的“部分已知”暴力攻击，每秒可尝试数千次，从而恢复有效的卡号。这对仍依赖离线校验的商户构成威胁。文章呼吁加快使用令牌化和 EMV 芯片认证，以降低此类风险。
**ARTICLE 10** **ENGLISH:** The Register reports that after a recent Falcon 9 launch, a large aluminium‑alloy component of the booster detached and survived re‑entry, eventually crashing into the Pacific Ocean, where it was briefly recovered by a fishing vessel. While the debris posed no immediate hazard, the incident highlights the challenges of controlled de‑orbiting of large rocket stages and may prompt regulators to tighten debris‑mitigation requirements. SpaceX’s reusable‑first philosophy will need to address such “orphaned” hardware to maintain public trust. **CHINESE:** 《The Register》披露，在最近一次 Falcon 9 发射后，助推器的一个大型铝合金部件在返回大气层时脱落并完整抵达太平洋，被渔船短暂回收。虽然碎片未构成直接危害，但此事件突显了大型火箭级段受控再入的难点，可能促使监管机构收紧碎片治理标准。SpaceX 的可重复使用理念必须解决这些“孤立”硬件问题，以维持公众信任。
