项目概述

这是一个“Show HN”（Hacker News分享项目）倡议，名为“Use Their ID”，旨在鼓励用户使用其当地英国议员（MP）的ID来应对《在线安全法》（Online Safety Act）。该项目可能针对该法律的监管影响，通过利用议员ID作为某种形式的倡导、测试或抗议手段。基于标题信息，其核心目的是关联议员身份与在线安全法应用，可能涉及匿名访问、内容审核挑战或公众意识提升。由于缺乏详细正文，具体实现结构、功能或技术细节未提供，仅可推断它是一个面向公众的活动或工具，焦点在于法律与个人身份的交互。

用集中式任务调度器替代Cron作业

Heartbeat公司原本使用多个独立的Cron脚本（如createScheduledPosts.ts、sendEventReminders.ts）管理定时任务，导致问题：需独立管理每个脚本、故障排查与修复困难、缺乏统一日志、易因时区等错误导致任务失败。为此，公司开发了集中式任务调度系统。

核心设计

• 单一数据库表 ScheduledTasks：存储所有任务，字段包括状态（QUEUED、EXECUTING、COMPLETED）、时间戳、优先级、过期时间、预期执行时间及负载（payload）。
• 负载（Payload）：使用区分联合类型定义任务类型，如发布事件、发送提醒、发送邮件等。
• 任务ID生成：对可编辑任务（如事件提醒）基于实体ID生成确定性ID，实现创建时更新而非重复创建；对一次性任务（如发送邮件）则使用UUID。

工作流程

1. 调度Cron作业：每分钟运行一次，筛选状态非已完成、时间戳小于当前时间+30秒且未过期的任务，按优先级排序后更新为EXECUTING状态，并为每个任务发送AWS SQS消息。
2. SQS消费者：监听消息，根据负载类型调用对应处理函数执行任务。
3. 完成处理：任务执行后标记为COMPLETED；若返回新任务则插入数据库。
4. 更新关联：实体变更时（如事件时间修改），通过确定性ID自动更新对应任务。

关键机制

• 重试与恢复：系统故障时，未执行任务仍存于数据库，恢复后可继续处理；过期时间（expirationInMinutes）控制任务是否延迟执行（如提醒类任务过期跳过，发布类任务永不过期）。
• 任务卡顿处理：预期执行时间（expectedExecutionTimeInMinutes）字段用于判断任务是否卡在EXECUTING状态，超时后重新执行。

系统优势

• 集中管理：统一日志、错误处理与监控，避免重复实现。
• 可靠重试：故障后自动处理遗漏任务。
• 执行记录：完整记录所有任务状态，便于问题排查。
• 扩展简便：新功能只需添加负载类型和对应处理器，无需新建脚本。

维基媒体基金会于2025年7月对英国《在线安全法》的“分类法规”提起法律挑战，认为该法规可能将维基百科纳入最严格的“第一类”监管义务范围，从而威胁其运营和全球志愿者社区。基金会指出，若被强制执行，这些义务将损害志愿者隐私与安全、使维基百科易受操纵，并分散其资源。

挑战的核心在于，法规要求可能迫使基金会验证许多志愿者的身份，这会破坏维基百科的匿名贡献模式，可能导致志愿者面临数据泄露、骚扰甚至专制政权迫害的风险。基金会强调维基百科作为非营利性公共知识项目的安全性与重要性，并指出它不同于法规所针对的商业高风险网站。

在诉讼中，一名英国志愿者作为共同原告参与，突显了该案件对普通贡献者的影响。这是首次针对《在线安全法》分类法规的法律挑战，也是首次有维基百科志愿者作为共同原告参与。

2025年8月11日，英国高等法院驳回了基金会的挑战，但判决中承认了维基百科的“重大价值”及其对用户的安全性，并指出错误的分类可能损害志愿者人权。法院强调，该裁决“并非为Ofcom和国务大臣实施严重阻碍维基百科运营的制度开绿灯”，并暗示若未能保护维基百科及其用户权利，他们可能面临法律后果。法官建议，Ofcom可能需要灵活解释规则，或由议会对规则进行修订。

2025年9月12日，基金会宣布不会就高等法院的判决提出上诉，但将继续监测法院指导意见的执行情况，并在《在线安全法》推进过程中保护维基百科。基金会期待Ofcom即将作出的分类决定，并继续寻求保护维基百科及其用户权利的解决方案。

基金会表示，它并非全面挑战《在线安全法》或第一类义务本身，而是针对可能对维基百科产生不当影响的分类法规。整个诉讼过程基于多年与监管机构和政策制定者的对话未果，以及议会和公民社会的警告。

If you’re a developer rocking an Apple Silicon Mac and writing in Zig, congratulations - you’ve chosen the scenic route through the desert of profiling tools. It’s just you, your code, and a tumbleweed named Apple Instruments. But don’t worry - we’ll try to find some oases. Okay, it’s not that bad, but we’re far away from the rich ecosystem of profiling tools available on Linux. Note: I have limited experience using low-level languages, so this article doesn’t provide a deep dive into profiling, but rather serves as an entry point to the world of profiling.
