@lcdtyph 错了，不是截图是是文本 🤣

@lcdtyph 老哥 我看有 mountinfo mounts mountstats 截图里是 mountstats 的输出，tid 是线程 id 吗？

@Jirajine 还有这种操作？那么有什么方法能看到被隐藏的进程吗？

@mikeguan 看过 没有

@mikeguan 但是问题是查不到文件夹为啥可以进去，而且进程都死了，不应该在 proc 下了啊

@lcdtyph ls -l

@mikeguan 不用加这个参数也可以看文件夹啊

@baiyi 最后一个太棒了吧，你们都是怎么找到这种资源的啊

@IceBay #1 老哥怎么说 刚开始用 Go 还不太懂 panic 和 error 的关系😂

@wqzjk393 那么如何学习概率论与数理统计呢

@lewis89 估计重学要 1 、2 年才行。。不过我确实非常非常想把基础弄牢固，就是一直没找到很好的切入点，怕半途而废

@lewis89 主要是协程这块弄懂了就行了

@rrfeng 看烦了主要是

@JamesR 感觉就像上面老哥说的就是个刷 kpi 的东西

@JamesR 正规公司呀，不是外包

@leafre 不是 9 字吗？(狗头
