最近两年眼见同事们陆续离开，时而感慨 “天下没有不散的筵席”。有的人带着新的希望去到下一站，有的人带着愤怒和倔强离开，有的人被公司裁员不得不离开，有的人依然期待着什么…

并不仅仅因为一些认识的人离开而让我感伤、叹息，也因为那些我不认识的人他们离开时包含感情的语句，和勾起我同样的经历的珍贵回忆，让我共鸣，让我惋惜。

摘抄一下一些真诚的、深刻的语句，也是我很喜欢且认同的经历。

（希望等我离开时，不仅仅是一句江湖再见，苟富贵勿相忘， 之类的俗套的话语；当然或许我什么也不会写到邮件里，甚至懒到不去发一封邮件。）

I’m leaving this office that has been more than just a workplace. It’s a place bursting with challenges, laughter, and invaluable lessons.

As I move forward, I carry with me not just experiences but relationships that I treasure deeply. Some of you have become more than my friends and an important part of my life. You know who you are, I would have expressed it to you personally at some point in the last 5 years. I cherish you and will continue to do so.

To those people: what a remarkable journey we’ve embarked on together. Each day spent with you was filled with moments of learning, joy, and immense fun. We’ve gone through things that seemed insurmountable, celebrated victories big and small, and sometimes, braved losses together. Every tough problem was lighter because I had you all by my side.

Thank you for the inspiration you’ve unknowingly bestowed upon me. It was your support that transformed my challenges into achievements and my doubts into confidence. Your memories will always echo in my mind, bringing a smile just as they often brought exhaustion.

有的人在工作中找到自己的乐趣，有的人能找到自己的挚友和同伴，也有的人只是当同事就是同事而已；无论如何，每个人都有自己对待工作、同事的态度，没有谁对谁错，只是收获的多与少，信任的深与浅。当今社会，工作占据了大多数的时间，与同事相处的时间可能比家人都多得多，如何对待他们每个人都有自己的观点。

Please keep in touch, I’ll do the same. I am excited about the future but will forever hold onto the past we shared with such fondness.

getopts、getopt的区别

在介绍如何使用getopts、getopt处理命令行参数之前，先来简单的说下getopt、getopts两者的各种特点和区别

首先来说getopts，getopts是shell中内建的命令，它的使用语法相对getopt简单，但它不支持长命令参数（–option）。它不会重排列所有参数的顺序，选项参数的格式必须是-d val，而不能是中间没有空格的-dval，遇到非-开头的参数，或者选项参数结束标记–就中止了，如果中间遇到非选项的命令行参数，后面的选项参数就都取不到了，出现的目的仅仅是为了代替getopt较快捷方便的执行参数的分析。

相反的是，getopts的缺点正好是getopt所具有的优点。相对于getopts而言，getopt是一个独立的外部工具（Linux的一个命令），它的使用语法比较复杂，支持长命令参数，会重排参数的顺序。在shell中处理命令行参数时，需要配合其他Linux命令一起使用才行。

总的来说getopts和getopt相比，getopts使用起来比较简单，但只支持短参数，getopt使用起来虽比较复杂，但处理的参数类型比较广泛

There are 3 levels of git config; project, global and system.

• project: Project configs are only available for the current project and stored in .git/config in the project’s > directory.
• global: Global configs are available for all projects for the current user and stored in ~/.gitconfig.
• system: System configs are available for all the users/projects and stored in /etc/gitconfig.

git支持多级配置，如：系统级、用户级、项目级、工作区级；它们的优先级如下：工作区级配置 > 项目级配置 > 用户级配置 > 系统级配置；每级配置记录在对> 应的配置文件中，通过 git config 命令设置的配置项 也都会写在对应的配置文件中，配置文件的具体信息如下：

• /etc/gitconfig ：系统级配置文件；对系统中所有用户都普遍适用的配置。若使用 git config 时用 –system 选项，读写的就是这个文件。
• ~/.gitconfig ：用户级配置文件；用户目录下的配置文件只适用于该用户。若使用 git config 时用 –global 选项，读写的就是这个文件。
• 当前项目的 git仓库目录中的配置文件（也就是工作目录中的 .git/config 文件）：这里的配置仅仅针对当前项目有效。若使用 git config 时用 > –local 选项 或 省略，读写的就是这个文件。
• 工作区级配置文件 ：这里的配置仅仅针对当前工作区有效。若使用 git config 时用 –worktree 选项，读写的就是这个文件。

面对不同类型的代码仓库，有时候我们需要使用不同的用户名，以及一些特殊一些的git参数。如何有效快速的设置，而不是按照一个一个repo去逐一的设置；但全局设置又兼顾不到一些剩余的代码仓库

编辑home目录下的 .gitconfig，按照如下配置的前提是：通常我们把一类代码仓库的放在一个目录下，例如按照公司名称来区分目录，或者是 gitlab_repo, github_repo这样来分。下面的代码片段只是展示最为简单的配置方法，可自行根据需求设置。

vim ~/.gitconfig

[includeIf "gitdir:~/company_a/"]
  path = .gitconfig-company_a
[includeIf "gitdir:~/company_b/"]
  path = .gitconfig-company_b

注意⚠️：

• gitdir 后面的目录路径在最后需要包含 一个斜杠 “/”；后面的 Conditional 规则也是支持灵活匹配的
• path 路径建议使用绝对路径

在对应的 .gitconfig-company_a 或 .gitconfig-company_b 文件中，参数的设置就如何普通的 .gitconfig 一样，例如下面的代码片段。

如果是一些字段(如user.name)的值是一致的，也可以无需在多个gitconfig文件中声明，只在 home目录下的.gitconfig 文件中定义一次，等同于运行命令 git config --global user.name "John Doe"

$ git config --show-origin --get user.email
file:.git/config	tomcat@companyA.net

$ git config user.email #并不能显示是哪个文件
tomcat@companyA.net

另外也可以通过命令的形式将参数写入具体的文件中，例如 git config -f 对应的配置文件/的路径/gitconfig_company_c user.email abcdef@qq.com`

更多详细的gitconfig中的参数可以参考 https://git-scm.com/docs/git-config，或者在本地用man命令查看, 如 $ man git-config

讨论面试这个话题

Well, we could have a mock interview. I could role-play as the interviewer and you cpuld pretend to be the interviewee.

Yup.Then the interviewer will want to know what actions you took to achieve your goal.

Exactly. And then the interviewer might ask you about a task, something you wanted to achieve.

I heard back from a few companies that offered me interviews.

How to Get Rich

不管你的外语说的如何，但礼貌是最基本的。或者说避免使用不礼貌的用语也很重要，不然会让对方误解，甚至生气等等

礼貌用语

不礼貌用语

来源：【如何更有禮貌的說英文】’’Excuse me’’的正確用法／別再說’’I want’’！

1. Wait

1. Hang on a second
2. Could you give me a moment?
3. Please can you wait a second?

2. 祈使句

在英语中，祈使句总体来说不太礼貌，比如：
Tell me.. ❌
Check something… ❌
Do something ❌

将其转变为一个疑问句会更合适一些
Could you let me know what time we’re meeting?✅
Please, could you have a look at this?

3. Already

“I already have done it” ❌
听起来有点儿防御性，似乎在质疑别人，潜台词是“难道不相信我吗”

4. I want

应该说 I would like

5. Hedgin

This way is better…

I think this way might be better. ✅
加入不确定性让句子听起来更礼貌一些

I don’t know why…
I’m not quite sure why… ✅

This was wrong…
I think there was something that might not have been quite right here. ✅

其他用语

The theory is now with you. Go get your hands dirty.
现在你已经掌握了这些理论了，放手干吧.

Exactly, they’ll sort it out and see if it’s viable plan, then the CEO will approve.
(if在类似场景的用法)

When is it due?
什么时候交？/什么时候到期？

My boss gave me this report at the last minute. I’m short on time.
…..我时间很紧张.

Not so great, James. I’m really nervous. Kyle told me that the boss is going to start firing people.

Thanks a million. I really appreciate it.

I am eager to use them. Is there something you want me to start on?

Considering your results, we’d like you to give a talk about the best practices.

有一些常用的模式在这种类型的邮件里，例如这一篇How to Reply to Thank You Emails (With Template, Examples and Tips)

Hope XXX gets better and better in the new year.

关于会议

按照时间线划分：

会议前 → 会议中 → 会议后

按照会议主题划分：

1. 交流工作、同步进展，就问题简单讨论；
2. 专门解决问题的会议
3. 产品/成果展示

我们通常需要提出自己的建议和见解，当然也需要提出自己的需求一次希望对方来完成某件事情；有时还要顾及其他的感受，主动询问别人的建议.
