Have you ever thought about this?
In 100 years, like in 2124, we will all be buried with our relatives and friends.
Strangers will live in our homes we fought so hard to build, and they will own everything we have today. All our possessions will be unknown and unborn, including the car we spent a fortune on, and will probably be scrap, preferably in the hands of an unknown collector.
Our descendants will hardly know who we were, nor will they remember us. How many of us know our grandfather’s father?
After we die, we will be remembered for a few more years, then we are just a portrait on someone’s bookshelf, and a few years later our history, photos and deeds disappear in history’s oblivion. We won’t even be memories.
If we paused one day to analyze these thoughts, perhaps we would understand how ignorant and weak the dream to achieve it all really was.
If we could only think about this, surely our approaches, our thoughts would change, we would be different people.
Always having more, no time for what’s really valuable in this life. I’d change all this to live and enjoy the walks I’ve never taken, these hugs I didn’t give, these kisses for our children and our loved ones, these jokes we didn’t have time for. Those would certainly be the most beautiful moments to remember, after all they would fill our lives with joy.
And we waste it day after day with greed and intolerance.

)其实想搭一套 paperless-ngx 已经挺久的了,
趁着四月底休假的时候搞了一动。
我们经常会有一些各式各样的 PDF 文档,例如和各种供应商、公司之间签署的文件、账单,
以及参加一些学术会议时留下的幻灯、资料等等。比较自然的办法就是创建不同的文件夹来分门别类地保存。
然而,简单地用文件系统来保存这些文件有这样一些问题:

今天来讲个关于备份的小故事。
以前有个同事之前在某使用UNIX的传统行业干了多年,他们的系统可用性要求不算高,但数据非常重要,
所以备份自然也是必不可少的。为了确保备份的安全性,
他们还雇了一家专门的保全公司定期把备份磁带从办公室拿走到该保全公司的仓库。

目前的经济形势下,许多公司都在进行裁员。大部分情况下,作为雇员对于公司是否进行裁员所能做的影响极为有限,
因此有必要提前对可能发生的裁员进行准备,以免仓促之下做出错误决策,或是在大规模裁员导致的踩踏事故面前束手无策。
本文主要是针对在美国境内工作的普通雇员,家里没矿,也暂时还没攒够足够退休的钱。
内容主要来自近期的阅读和想到的一些东西,算是给自己留下一些笔记。
