USB桌面管理器

如果有这样一个设备,内置一个USB Hub,对电脑只有一个USB插口,允许你把你所有的各种USB线都插上去,并帮你把这些USB线绕起来,估计会很受欢迎。

想象一下。当你买来一个新的电子设备,又有一种新的USB线。你就把这根线插到这个盒子里,盒子自动把你的线收回到自己肚子里,把接口留在外面。当你有很多种线的时候,这个盒子肚子里就有很多线。你永远只需要把电脑和这个盒子连起来。

当你需要用某种接口的时候,就用手拉一下这个接口,这个接口自动把线送出来。用完了按一下,再自动收回去.....当你需要把线带走的时候,很容易把线拿下来。

It's xmas here

And your xmas eve, honey. I cannot get you by your mobile. Pick up the phone, girl.

I finally got you, girl. After many try. But it does not seem you like talking with me. You have your happy life over there, that's great. Really great. I don't know, but I can feel something at the other end of the line, oversea.

Your xmas eve is fun, your xmas will be fun, and your new-year-eve will be fun. Have fun, baby.

Tomorrow is xmas

Merry xmas there, my honey. Enjoy your ever best xmas!

Redhat中的IO性能

今天在测试中发现,Redhat中的小size random IO性能特别差。测试中测试了两个Redhat版本:AS 3 Update 6和AS4 Update2,同时测试了本地硬盘和光纤存储,小size random IO性能实在是太差。IOmeter测试的结果显示单线程4KB 100% random IO的性能才只有几百KB。

有人知道为什么吗?

我想我基本明白了原因。

IO size = 4KB,所以每一个I/O,只有一块硬盘在发挥作用。因此IOPS就受限于单块硬盘的性能。而单块硬盘的性能可以做如下的分析:

146G的10KRPM硬盘,比如seagate的,参数如下(link):

  1. Full Disc Seek, Read 9.5 msec typical
  2. Full Disc Seek, Write 10.3 msec typical
  3. Average Latency 3 msec
所以,在最坏情况下,每一次读Cache都会失效,都需要从硬盘重新读数据。一次最长时间的Seek需要大约13ms,这样IOPS = 1000 / 13 = 77。Bandwidth = 76 * 4 = 307 KB/S。

Google Homepage

http://www.google.com/ig

其实这样的功能很久以来大家都在做,象以前的my.yahoo.com(现在也许还有,但我很久没用过了)。google却能把大家都在做的事情做到最好。

Google Homepage初看起来似乎只是rss的aggregate,但当google开放了它homepage的API后,一切都不一样了,Google Modules证明了这一点。

尝试一下LiveJournal

工具的力量是无穷的,竟然有FireFox里的插件支持离线发布LiveJournal,再加上LiveJournal OpenSource的开发方式,Clean的界面。试试吧。

考试终于过了

CLARiiON Specialist, passed at 82%. 也不觉得怎么爽,考试的内容也挺没劲的,都是考些背的东西。

还要继续准备下周二的Seminar和下周三面向全国Telco CSL的session。这些破事为什么做起来都没兴趣呢?

又是一天

停车,上楼,开门。门里依然是一片漆黑。

没有声音,没有人,更加没有做好的热气腾腾的饭。

Visit, Individual, Seminar, Engagement, MBO... 每天和这几个词纠缠,这是成长吗?

看书,学习,准备考试。自己选择换了行业,换了工作性质,只能自己把自己归零,一切从头。

欧亚大陆的另一端,七个小时的时差,不长也不短。亲爱的,我不知道你面对全新的一切的时候有没有特别希望我陪在你身边。如果你是这样的,那你和我一样。

我离开的公司继续着每年一次的动荡,不知道如果我不离开的话有没有可能还继续拥有从前的位置。

向前看,向后看,都看不清。

What does EMC stands for

EMC stands for Egan, Marino, Corporation. And the superscript "2" is
only a design element.

Backup your disk

The hard disk is not reliable, neither portable hard disk. We need
desktop backup. I started to use the EMC Dantz Retrospect to backup my
hard disk to DVD RW today.

You need to make your own backup plan from now.
