早前看了這個 J.J. Abrams 的 TED 演講 ，主題是「The Mystery Box」。他說了很多，有點抓不著重點，但比較深刻的是他最愛的《Jaws》裏的一幕，不是大白鯊的特技，而是父子一幕。他說那些怪物啊、鯊魚啊都不是重點，真正在 mystery box 裏的東西

看now tv24小時新聞台，真會感覺置身一個不同的世界，比較令人心平氣和，因為該說的話有人替你說了。報導的新聞不多，但有脈絡有深度，有著隱性的規勸意識。知性而平民，編輯向度有力，比如有別於鋪天蓋地的「辭

Why I believe that you want Solaris if you want ZFS
As Wolfgang Lonien recently pointed out , Solaris isn't the only systemwith ZFS, as you can also get it in at least FreeBSD. Despite theseports, I believe that Solaris generally remains your only solid choiceif you need ZFS.
The problem is that ZFS is currently incomplete, with both missingfeatures and significant problems . Thismeans that the work of integrating ZFS into other systems is notcomplete, and there are two potential issues with the remaining work.
The first is the most straightforward: you are taking

你為什麼不快樂？
全世界都趕在農曆年前後向聯交所入A1表。這陣子，凡是有IPO deal在手的都忙得頭昏腦脹。看看日曆，shit！原來已是一月中，我白白錯過了今年的Christmas sale！
反正今天下午沒有conference call，我決定偷走出去IFC Mall進行精神排
Layering buffering on top of other buffering is usually a bad idea
Here's something that I've seen illustrated more than once : layering buffering on top ofbuffering is almost always a bad idea .
One of the reasons is that it can be tricky to write a correct version.For example, consider all the things that you have to get right if youwrite a file IO buffering layer on Unix, including:
- you must remember that you've seen an EOF, and return this indicationto the next level up without doing another underlying
read(). - you must return
Why the x86 Linux kernel is part of every process's address space
In an earlier entry I mentioned that theLinux kernel takes the top 1 gigabyte of a process's address space foritself. In fact this is not just address space that the kernel reservesfor its own use; the entire kernel itself actually lives in the topgigabyte of every process's memory map.
(You can't read it or run it because it is protected address space,accessible only when the system is in kernel mode, except for the VDSOit exports to processes these days.)

What seems to use power on an Asus Eee PC
Courtesy of having an Eee around and being curious about how to maximizethe battery life, here are some measurements about what bits seems touse how much power. All of these measurements are for a '4G Surf' model;your mileage may vary on other ones.
First, a disclaimer: all of these measurements are made with a powermeter while the Eee was on wall power. It's possible that the Eeebehaves differently when running on battery power (although I wouldbe somewhat surprised).

Blunder
Not long ago, a survey in Massachusetts General Hospital told us that nearly half of doctors admitted to witnessing a serious medical error but not reporting it. According to another survey published this week, most doctors in three United States teaching hospitals agreed that reporting errors improves quality of care, although only a little over half said they understood how to do so; only 18% said they had actually reported a minor error and 4% a major error.
How can this be, I muse, that reporting medical errors lead

Lab notebooks are not changelogs
Here's something from my previous entry thatI should clarify: lab notebooks are not changelogs .
Lab notebooks and changelogs are two different things. Lab notebooksare scribbled at the time for yourself, and should includeeverything. Changelogs are written after the fact for other people, andshould include only the things that actually turned out to matter.
In other words, changelogs are the sysadmin equivalent of lab reportsand scientific papers. You can no more use a lab notebook as a changelogthan you could submit a lab notebook
