天文学家确认了 25 光年外的一颗位于宜居带的岩石行星
天文学家确认一颗名为 GJ3378b 的系外行星，位于距离地球仅 25 光年的红矮星宜居带内，可能具备孕育生命的条件。这颗行星位于鹿豹座方向，围绕一颗暗淡的红矮星运行，被视为目前已知距离地球最近的潜在宜居世界之一。GJ3378b 最初于 2024 年被法国天文学家发现。当时测定的质量为地球的 5.26 倍，被认为是一颗类似微型海王星的气态行星。天文学家利用基特峰国家天文台的 WIYN 3.5米望远镜等设备进行二次观测后，修正了这一结论。新数据显示，GJ3378b 的真实质量仅为地球的 2.3 倍，属于岩石质地的“超级地球”。轨道参数同样得到修正。最初认为该行星的公转周期为 25 天，实际仅为 21 天。这意味着它比此前判断的更靠近母星，但也恰好处于宜居带内——这一区域允许行星表面温度维持液态水的存在。这颗行星从母星接收的辐射量约为地球从太阳获取的 90%，位置非常理想。 via Solidot

《半秒钟》——XZ 后门启示录
2024 年 3月 29 日，一位微软工程师在家执行例行测试时，发现登录测试机的时间比往常慢了约半秒。大多数人都不会认为这是什么大问题。但他却深入展开了调查，在流行压缩工具 XZ Utils 中发现了一个故意植入的隐蔽后门。有人花了两年时间才把后门植入到该工具中。Adrian Mastronardi 发表了一本关于 XZ 后门事件的书《Half a Second》，在非商业使用、禁止衍生的 CC 许可证（CC BY-NC-ND 4.0）下免费提供。本书讲述了一位精疲力竭的志愿者独自维护着代码，被耐心而巧妙的操纵，最终交出了代码的维护权；一位工程师凭借一连串的运气和来之不易的直觉，在半秒钟的好奇心驱使下发现了这次攻击；以及构建该后门的幕后操纵者，此人至今身份不明，其身份可能永远也无法被揭露。 via Solidot
