Tune your ext2/3 filesystem, from Gentoo Weekly Newsletter (October 17th, 2005)
ext2/3 are the main filesystems for a large amount of users but what a lot of people don’t know is that you can get almost Reiser4 speed out of it without any of the instability they’d associated with Reiser4. One of the great features of ext2/3 is the ability to tune it by adjusting various parameters. The one we are going to modify here is dir_index which essentially uses hashed b-trees to speed up lookups in large directories.
Let’s take some precautions, first of all by finding out if some of those parameter are already enabled, by running
# tune2fs -l /dev/hdXX
(replacing XX with your drive and partition your ext2/3 filesystem resides in). If you don’t see dir_index in the list then we can enable it, and just in case you do see dir_index in ‘Filesystem features’ then you have either enabled it already or it was automatically enabled for you.
You are going to need a Gentoo LiveCD because changing parameters on mounted filesystems can cause problems, so in the interest of safety we are booting off the CD. At the start phase the Gentoo install system is booted into what’s called a “ramdisk” which is where the files needed are put into RAM to be used. mke2fs, tune2fs and other parts of the e2fsprogs package will be present at this stage.
Now let’s turn on the feature with
# tune2fs -O dir_index /dev/hdXX
Now run e2fsck with the -D option to have the directories optimized:
# e2fsck -D /dev/hdXX
Do that on any ext2 or ext3 partition and then reboot. You should notice the difference straight away.

Gates donates $15 million to computer history, from CNET News.com.
很諷刺的, 我竟然看成 Gates donates $15 million to computer his story, 直覺上就變成比爾蓋茲捐了一千五佰萬美元給他的電腦傳奇. Orz

Apple 的 iTunes 其實還蠻好用的, 也有 Podcasts 可以訂閱. 目前 iTunes 的 stable version 是 6.0.0.18.
雖然 iTunes 是免費的, 但是卻會順便裝 Apple QuickTime, 很遺憾, 我非常不喜歡 QuickTime Player, 這是也我不喜歡 iTunes 的原因. 後來有試出一個方法可以只裝 iTunes 不要裝 QuickTime Player 的方法, 那就是裝 K-Lite Mega Codec Pack 或是 QuickTime Alternative. 不過隨著 QuickTime 也更新到 7.0, 這個方法也要作小小的更改. 步驟如下:
要注意的是 QuickTime Alternative 一定要用 1.65 以上 (aka K-Lite Mega Codec Pack 1.40 以上), 用 1.53 的話, 裝 iTunes 6 時會偵測到系統中沒裝 QuickTime 7, 一樣會幫你裝進 Computer System 中而前功盡棄.
那原先的 QuickTime 影片 (.mov vice versa) 怎麼播呢? 事實上用 Windows Media Player 就可以播放囉!
