A quick note about how extended partitions work
Hard disk partitioning on PCs is one of those confusing areas, full ofpeculiar features and apparently random limitations, especially thewhole primary partitions versus extended partitions thing.
Fortunately, it's actually fairly simple:
- primary partitions are just a fixed size array in the firstsector (the master boot record, among other things).
- extended partitions are a chain (a linked list).
Each extended partition starts with a sector (the ' extended masterboot record ')that describes how big it is and then points to
blog人十問
前輩問我關於寫blog的事
我以為
我沒有資格多談
因為我寫blog只是貪得意
電腦技術又不好
根本沒有深入了解這種文化
這件事
令我思考寫blog對我們生活的改變
我現在除了讀報紙
也會透過別人的blog來了解社會萬象
也許
有些朋友也會
世界大變
五年前今日
世界大變
這些年來我都在想
這麼辛苦工作有什麼用
賺了錢有什麼用
忍氣吞聲有什麼用
這個地球根本每天也有機會“一鑊熟”
有時候做人真的難免悲觀
特別在911這種怨氣十足的日子
寫blog差不多十個月

Python's extra-clever help() function
I recently used ' help() ' on one of my own internal modules, mostly asa quick way to browse the entire function/class collection in one go.Now, I'm kind of a slacker when it comes to using docstrings (for somereason I prefer comments before the function), so I didn't expect tosee very much in the help() output.
Much to my surprise I saw things like:
hostFromEnv(env) # Extract the host from the # REQUEST_URI
'In place' filesystem defragmentation with Disksuite
While the Berkeley FFS and derivatives like Solaris UFS are much, muchbetter at dealing with fragmentation than the original V7 filesystem(which continued on into System V before SysVR4), they can actually getfragmented over time to a degree that matters.
Traditional Unix, Solaris included, really doesn't have any tools fordefragmenting filesystems; instead, you get to to do it the bruteforce way, by copying everything into a clear filesystem. With SolarisDisksuite and mirrored disks, it is possible to do this

中國入唔到決賽有少少慘，其實我憎巴西多過中國好多。技術好鬼呀巴西。只係身體質素唔錯之嘛。而家傷兵處處，世界女排球壇的形勢真係好古怪。俄羅斯無端端咁都可以入到決賽，除了加莫娃醒番

A thought on iTunes and similar online services
What iTunes and similar online services are really selling isconvenience and guilt-avoidance, with a small side order of helpingout the artists. They're manifestly not selling the music itself (orvideos or etc), since you can find them online yourself if you look hardenough.
The 'helping out the artists' bit is currently only a small side orderbecause most everyone understands at some level how little of the moneyinvolved actually makes it to the artists.
The guilt-avoidance is not a good long
