The story starts in Crosscord, the crossword Discord server. Over 5,000 users strong, the server has emerged as a central hub for the online crossword community, a buzzing, sometimes overwhelming, sometimes delightful town square where total noobs, veteran constructors, and champion solvers alike come together to talk about words that cross each other.
Hacker News was written in the Arc lisp dialect, a dialect created by Paul Graham. Arc was implemented on top of Racket, but that has now changed. HN runs on top of SBCL since (at least) September of 2024.But why? For performance reasons. I recently noticed that Hacker News no longer uses paging for long threads. In the past, when a discussion grew large, we had to click “More” to load the next page of comments, and dang would occasionally post helpful tips to remind us about this feature.

库珀鹰利用交通信号捕猎的观察记录
Dr. Vladimir Dinets，田纳西大学动物学助理教授，在《Frontiers in Ethology》期刊发表文章，记录了库珀鹰（一种北美中型猛禽）在城市环境中如何利用交通信号提高捕猎成功率。观察发生在家附近的十字路口：当行人按下过街按钮时，红灯持续时间延长，车辆排成长队，同时交通灯发出声音信号提醒盲人安全过街。
捕猎行为细节：库珀鹰在声音信号响起后，从隐蔽的小树中飞出，沿车辆队列低飞，利用汽车作为掩护，接近房屋前的鸟类群（如麻雀、鸽子等），发起突袭。鹰只有在车辆排队足够长、提供完整掩护时才攻击，这需要它理解声音信号与队列长度的关联，并依靠心理地图记忆猎物位置。
智能与适应能力：观察中的鹰是未成熟的冬季迁徙个体，但迅速学会了利用交通信号。这体现了库珀鹰作为少数成功适应城市的猛禽，通过智能应对复杂环境中的危险（如车辆、窗户），提高生存效率。
动物利用车辆的广泛现象：文章提到其他例子，如乌鸦用汽车砸开坚果、鸟类以移动车辆为掩护躲避天敌，但库珀鹰的行为更突出，它整合了人类交通信号系统，展示了高级认知和学习能力。
意义：这一观察强调了动物行为的灵活性和智能在城市生态中的重要性，库珀鹰通过创新策略克服城市挑战，维持种群生存。
AI isn't replacing developers, it's transforming them. Just as NoCode created specialists and cloud turned sysadmins into DevOps engineers, AI elevates engineers from code writers to system architects. The most valuable skill isn't writing code, it's designing coherent systems.

Here's a common question we get from prospective Cline users: "How does Cline handle large codebases? Do you use RAG to index everything?"
It's a reasonable question. Retrieval Augmented Generation (RAG) has become the go-to solution for giving AI systems access to large knowledge bases. But for Cline, we've taken a deliberately different path. We don't index your codebase, and this choice isn't an oversight, it's a fundamental design decision that delivers better code quality, stronger securit

1952年5月13日，美国内华达试验场进行“翻滚-狙击手”战术核武器测试。代号“狐狸”的15千吨当量核弹未能按计划起爆，滞留在300英尺高的测试塔顶，对周围数英里范围构成严重威胁。
作为原子能委员会测试负责人，约翰·克拉克博士面临解除引信的艰巨任务。他带领工程师赫布·格里尔和巴尼·奥基夫攀爬塔架（电梯已拆除），进入装有故障核弹的测试舱。通过内部电话连线控制中心进行实时汇报后，克拉克徒手拆解马克V型核弹外壳，逐步解除包括新型钋-铍中子发生器在内的内部点火系统。尽管核爆风险已排除，但装置内仍存有足量常规炸药。
值得注意的是，这已是克拉克第二次执行此类高危作业。1951年10月，在“破坏者-丛林人”行动中，他已成功解除代号“糖”的1.2千吨当量故障核弹。
事后调查发现，“狐狸”弹药故障源于配套仪表系统失效，该系统错误地覆盖了自动发射序列。12天后（5月25日），修复后的“狐狸”弹药成功起爆，约500名军事观察员和950名装甲步兵在前沿阵地记录了爆炸效应。
克拉克作为原子能委员会首席起爆专家，职业生涯中亲手引爆的核武器数量超过绝大多数同行。完成这次36小时连续作业后，他返回基地休息。

In this post, I demonstrate the optimal workflow for creating new Debian packages in 2025, preserving the upstream Git history. The motivation for this is to lower the barrier for sharing improvements to and from upstream, and to improve software provenance and supply-chain security by making it easy to inspect every change at any level using standard Git tooling.\nKey elements of this workflow include:\nUsing a Git fork/clone of the upstream repository as the starting point for creating Debian packaging repositories. Consistent use of the same git-buildpackage commands, with all package-specific options in gbp.conf. DEP-14 tag and branch names for an optimal Git packaging repository structure. Pristine-tar and upstream signatures for supply-chain security. Use of Files-Excluded in the debian/copyright file to filter out unwanted files in Debian. Patch queues to easily rebase and cherry-pick changes across Debian and upstream branches. Efficient use of Salsa, Debian’s GitLab instance, for both automated feedback from CI systems and human feedback from peer reviews. To make the instructions so concrete that anyone can repeat all the steps themselves on a real package, I demonstrate the steps by packaging the command-line tool Entr. It is written in C, has very few dependencies, and its final Debian source package structure is simple, yet exemplifies all the important parts that go into a complete Debian package:\n
