21. There is a huge pool of exceptional junior engineers (workweave.dev)

文章摘要

本文基于作者面试134名工程师(从学生到CTO)的经验,指出当前人才市场存在一个被大多数公司忽视的巨大且优秀的初级工程师人才池。文章主张,当所有公司都在争抢高级工程师时,聪明的公司可以通过重点招聘初级工程师来获得显著优势。

公司为何回避初级工程师?

  • 小团队借口:认为没有时间指导,需要即刻高效产出的成员。
  • 中型公司借口:认为需要能处理规模挑战的经验者。
  • 大公司借口:认为基础设施复杂,初级工程师上手过慢。
  • 核心心理是雇佣有经验者更“安全”,尽管其天花板可能不如有动力的初级工程师。

初级工程师的优势

  • 思维不受束缚:没有固有流程或技术偏见,更易适应变化。
  • 学习与反馈意愿强:渴望进步,易于管理。
  • 成长天花板更高:处于职业成长曲线的起点。
  • 为团队注入活力:其求知欲和证明自己的动力具有感染力。

公司招聘流程的过时与误区

  1. 低估上手速度:优秀的初级工程师在AI等工具辅助下,能比传统预期(6-12个月)更快地进入状态。
  2. 面试方式过时:仍侧重算法记忆和白板编程,而这些技能在AI时代相关性降低。
  3. 搜寻渠道单一:错过隐藏人才,例如那些申请Y Combinator但未入选的开发者(往往极具动力和潜力)。

如何正确招聘初级工程师(五步法)

  1. 筛选正确思维:深入追问其项目经历,考察思考深度、好奇心与热情。
  2. “自由使用工具”的家庭作业:布置小型现实编程任务,允许使用任何工具。后续面试重点在于考察其理解自己提交的代码的能力、决策理由和技术深度。
  3. 无AI的问题解决:通过系统设计等面试,评估其独立思考和基础工程思维
  4. 使用AI的实时编码:观察其如何与AI工具协作,包括提示策略和迭代优化。
  5. 评估其AI策略:请候选人阐述其开发工作流,判断其是否能在“使用AI”和“手动编码”之间做出合理选择,既不过度依赖也不抗拒AI。

成功雇佣后的关键行动

  • 投资指导体系:分配导师时间,规划学习路径。
  • 耐心看待短期产出:给予学习公司业务和技术栈的时间。
  • 衡量正确指标:关注上手速度、留存率和障碍。
  • 积极沟通:倾听他们的体验和建议,及时给予认可。
  • 从小规模开始:先招聘1-2人,验证模式后再扩展。

结论

作者认为,避免招聘初级工程师是一个巨大错误。公司正在错过这些AI原生、学习能力强、能快速成长为卓越高级工程师的人才。当前市场低效不会永远存在,像Shopify(计划招聘大量实习生)这样的先行者已开始行动。在AI时代,能有效招聘和培养初级工程师的公司将建立强大团队,获得长期竞争优势。

45. Show HN: Every single torrent is on this website (infohash.lol)

这个网站灵感来源于类似keys.lol和everyuuid.com的项目,旨在展示BitTorrent协议中所有可能的torrent。每个torrent由一个唯一的40字符十六进制"infohash"标识。网站枚举了所有可能的infohash(数量级约为10^48),并以每页32个的方式显示,总页数超过4.5×10^45页。

工作原理:BitTorrent客户端可通过分布式哈希表(DHT)将自己作为特定infohash的潜在peer进行广播。当用户加载一个infohash页面时,网站会对每个infohash发起DHT查询,寻找广播的peer。如果找到peer,网站会进一步向这些peer请求该infohash的元数据,例如torrent名称和包含的文件列表。

示例

  • "Ubuntu 24.04.3" torrent的infohash为d160b8d8ea35a5b4e52837468fc8f03d55cef1f7
  • "Sintel" torrent的infohash为08ada5a7a6183aae1e09d831df6748d566095a10

随机找到一个活跃infohash的概率极小,但并非为零。

:网站仅展示通过DHT广播的torrent,使用私有tracker的torrent不会显示。

常见现象解析:许多torrent显示单个peer但无法获取元数据,原因包括:

  1. infohash无验证:任何客户端都可以广播任意infohash,许多爬虫和索引器会随机或顺序选择infohash进行广播以检测其他广播者,恶意客户端或错误编写的程序也会向网络发送垃圾信息。
  2. 协议不支持:合法peer可能不支持交换元数据所需的协议扩展。

作者其他项目:网站作者还创建了Library of Babel,该项目包含所有可能的书籍内容。

46. Don't Become a Scientist (1999) (yangxiao.cs.ua.edu)

文章《别成为科学家》(1999年)摘要

核心观点:
华盛顿大学物理学教授乔纳森·卡茨指出,尽管科学研究本身充满乐趣,但美国的科学职业路径已变得不合理,年轻人应避免进入科学领域。

主要问题:

  1. 人才过剩:美国大学培养的博士数量远超市场需求,导致供过于求,许多科学家长期处于“临时博士后”状态。
  2. 职业前景黯淡
    • 入职时间漫长:与过去相比,获得永久职位的时间大幅延长(从平均2年增至5-10年以上),期间需频繁更换工作、搬家,缺乏稳定保障。
    • 薪资水平低:博士后起薪较低(例如生物学约2.7万美元,物理学约3.5万美元),难以支撑中产家庭生活。
    • 对比其他行业:医生、律师、计算机工程师等通常在更年轻时获得稳定高薪工作。
  3. 即使获得永久职位,困境依然
    • 获得终身教职后,需面对激烈的经费竞争,耗费大量时间撰写研究提案而非专注于科研。
    • 提案评审受竞争对手影响,原创性想法容易因“未经证实”而被否定,限制了研究自由。

原因分析:

  • 联邦资助政策是造成博士过剩的根本原因,且资助机构未能根据实际需求调整培养规模,甚至曾散布“科学家短缺”的不实预测。

建议:

  1. 对个人:应选择其他职业(如医学、法律、工程、计算机等),避免陷入科学职业的困境。
  2. 对科学界领导者:应推动资助机构将博士培养数量与市场需求匹配,恢复科学的合理职业路径。

结论:
作者基于自身经历和观察,强烈劝阻年轻人从事科学研究职业,认为当前的科学就业市场会导致多年奋斗与失望,并建议寻求其他更具前景和稳定性的职业选择。

世界最高桥梁花江峡谷大桥已于中国贵州省正式开通。该桥横跨峡谷,桥面距地面高度超过2000英尺(约600米),全长2890米,建设历时三年多。大桥的建成将峡谷两岸的通行时间从两小时大幅缩短至两分钟。

中国外交部发布的无人机视频显示,大桥下方通过“壮观的水幕测试”形成了彩虹景象。为确保大桥结构安全,上月工程师团队使用96辆卡车在桥面多点位进行负载测试,模拟重交通压力,以验证其承重稳定性。
