@ImACat traceroute 借助 ICMP 实现的，理解大概好像不难。。。。我也不是很懂😂

看看 traceroute 的实现原理，对 IPIP tunnel 能实现吗？

关于头像的规则和建议

- V2EX 禁止使用任何低俗或者敏感图片作为头像
- 如果你是男的，请不要用女人的照片作为头像，这样可能会对其他会员产生误导
- V2EX 建议你不要使用真人照片作为头像，即使是自己的照片。而使用别人的照片则是被禁止的行为

我觉得这个建议蛮好的，我也一直在遵守。

@iceneet 😢😒

很不错，已下载

只说一个我知道的，Shell 是和 Kernel 相对的，一个是壳一个是核。早期没有图形化界面。交互方式也就是输命令行。但是后来有图像化界面了，Shell 就专指命令行了。https://imgur.com/c1YLzQP

如果只买一个 XM3 不建议，带久了耳朵很热，尤其是夏天。建议两个都买。

@WiredcraftHire It may disappoint you, but I am not a digital talent. I really don't think I deserve your appreciation. Although our lab does develop some applications to solve problems specific to our industry,my major is not software engineering or strongly related. I am trying to catch up on fundamental knowledge of CS like OS, networking, computer architecture....I learn by watching tutorials on YouTube and Udemy I touched many tech stacks part of because my mentor launched many projects which failed at last. I haven't prepared a resume yet and I am doing an internship in a company which has academic cooperation with our lab. I hope I will be qualified when I seek for a development job in the future :), and I will keep eyes on your company because I really want WLB.

@yanjinhua 我意思是太老了，建议 Win10 Fluent Design 风格。当然如果你这个项目 UI 并不是重点，当我没说 o 。

@WiredcraftHire 招应届生吗，今年秋招来学校吗？

不明白你装了啥软件，但是你说的情况我没体会。WIndows 也很好用。

这算外包吗？
