整了台华为的UPS（UPS2000-A-3KTTS），2400W 3000VA，内置6个9AH电瓶，容量大，本来计划是放在书房里顶替掉APC BR1500G（感觉容量不太够）。但是我低估了在线式UPS全程风扇满转的噪音.. 最后决定还是放到地下室给机柜用吧.. [允悲]

书房还是适合后备式UPS，平时无噪音，主要是带电脑和一堆网络设备，之前买的APC BR1500G（865W 1500VA，2个9AH电瓶）一直觉得容量不太够，而目前比较大容量的后备式UPS好像只有BR1500G首选。BR1500G有一款非常不错外接扩展盒（BR24BPG，4个9AH电瓶），插在BR1500G就能直接给它扩到3倍容量，但是这玩意国内没有行货... 由于非常重，代购和自己海淘也不便宜.. 愁..

目前，初步计划是再整一台BR1500G，两台串一起用，不过就是成本有点高了.. [允悲]

“真正的问题不在于长大，在于遗忘。”

——《The Little Prince》

在这个复杂的社会中，愿你的心中永远住着一个小王子。没有人能永远保持年轻，但永远不要忘记曾经那颗简单、单纯的童心。All grown-ups were once a child, though, only a few people remember.

“恭喜你长大成人，愿你归来仍是少年。”

容易混淆的词
Who vs. whom: Even a grammar wiz can get these two confused from time to time. But if you can switch the sentence around so that you use the word "him" as opposed to "he," then "whom" is the way to go. For example, instead of saying, "Sam is the guy whom we interviewed for the position," you could say "We interviewed him for the position." But in reversing the sentence "Sam is the guy who got the job," you would say, "He is the guy who got the job."
Who和Whom：就算是语法大师也很容易把这两个词搞混。不过要是你能想一想同一句话用“him”和“he”会怎么表述，你就很容易就能去区别出这两个词了。比如说，“Sam is the guy whom we interviewed for the position Sam是我们为这个职位面试过的人”这句话你也可以说成“We interviewed him for the position 我们为这个职位面试了他”。然而“Sam is the guy who got the job Sam是获得这个职位的人”这句话则会表述为“He is the guy who got the job 他是获得这个职位的人”。
