科幻先生海箂因 (Robert Anson Heinlein) 有一本叫 《夏之門》 (The Door into Summer) 的作品，是一個蠻有趣的時空交錯故事，但故事主角戴維斯的工程師良心，卻叫我看得佩服。
戴維斯很有才華，熱衷於發明研究，戰後在一家廢置工廠做自動化機器人
UPSes: defense against problems, or sources of them?
Here is something that we have been forced to think about lately: areUPSes really a good insurance policy against power problems, or are theyinstead an extra source of problems? In short, does using UPSes reallyincrease your net reliability?
The problem with UPSes used by themselves is that they are another pieceof machinery to fail (and they are a moderately complicated piece ofmachinery at that). And UPSes do fail; for example, we recently hadan incident where a UPS reset itself out of the blue,
隨筆雜念
我曾經有一段時間認為，萬一家裏發生火災，只能夠帶一樣東西離開的話，我可能就會把電腦拿走。原因就是實在有太多工作、太多回憶放在裏面了，有一些失去了的話就補救不了的資料，例如大量的合照和文章，即使能夠用光
Why I Love the D3...
I was simply running and gunning around my condo in very dim lighting this evening, and I am continually amazed at the sharpness, the clarity, and the beautiful colors that come out of the D3. Granted, pairing it with the amazing Nikon 50mm f/1.4 is much akin to pairing cream and a doughnut... but still:

一個難譯的字
我的研究專長是知識論，在知識論裏有一個經常出現的英文字，卻不是哲學術語，而是平時也經常會用的字： "belief" 。這個字，我認為很不容易譯成中文。

Share a Proxied Network Connection via WiFi to your iPad/iPhone/iPod
For the past six weeks that I've had my iPad, I've fought with my office network, because it uses a Microsoft/NTLM authenticated proxy server which wreaks havoc on the iPhone OS's ability to use the Internet effectively (especially for third party apps).
After reading through countless forum support requests for people asking the same questions, I've finally found a (mostly) workable solution for this problem—at least for most apps and browsing on the iPad.

Why I am really unhappy with ZFS right now: a ZFS import failure
We almost lost a ZFS pool today. More accurately, we did lose a ZFSpool, and then we were able to get it back because we were lucky enoughto have a Solaris 10 update 8 test machine handy. But except for thatbit of luck, we would be in the very uncomfortable position of tellingan important research group that for the first time ever we'd just lostnearly a terabyte of data, and it wasn't even because of a hardwarefailure, it was because of a
