Two search engine, AOL and Google……

AOL Research&Learn

Mydrivers.com posted a news about AOL Research&Learn. It’s a online study and research site for K-2 to 9-12 grades students, and convers Math, Social Studies, Language Arts, Health, Science, Electives and so on.

I tried to search Calculus section from Math. Articles about calcules displayed in a well formated manner. I think this will help students concentrate on the information he or she wants but the advertisements. A little more, note on the left page, Dictionary and Thesaurus are ready for you! Study everywhere should be possible if our eduction were like this~!

Games are always avaliable in American student’s study. See, lots of games are here. Learning should be happy for children, so does adults. So let’s us play suduku together~!

Google books

It’s amazing that you should search for books online~!

Google books now can search for Chinese books here. I try to search a famous person Mengzi, and Google returns several books. Picture above is a book, note the yellow region is what I;m searching. But you can’t see all the pages, note the Limited Preview above the page. You should buy this book. I regard this as a commercial plan for Google and the book sellers—-Google searchs and one sell.

So this will help us only to know what book I want, not as I think it will display all the pages. Free is not always for Google. And free is not always for the world.

Money, all we live for is money~

I installed SuSE Linux Enterprise Desktop 10 on my Desktop computer and Benq Joybook 3000 notebook. Both of them can’t wake up from suspend. I try to disable ACPI when start up from GRUB and my notebook can wake up, but screen can’t restored and displays error image.
Time is limited for me, so I won’t try more. If suspend to ram can’t work on both of them, it should be regret to SuSE SLED 10.

今天庆祝妹妹上学，弟弟妹妹都在我家里面玩，只好安装一个早上下载的SuSE Linux Enterprise Desktop 10。这个版本是最近才发布的。本来是本着无聊的心情去下载的，结果安装后发现改进确实很令人兴奋。速度大有提升，XGL效果也很好(虽然说以前看过)，很多地方也有人性话的地方。说实在的，现在感觉Vista并不是那样的令人激动。

以前用过OpenSuSE，给人的感觉就是慢。毕竟还是一个开源的项目，可能在优化上面还比不上专业的商业软件了。但是要想用QQ就麻烦了，安装了OpenQ for Gaim还是不行，555，恐怕真的有点点麻烦。

后来用了Gaim 2.0的SVN版本就可以了，很是高兴哦：)

看有没有必要在笔记本上安装一个玩玩～～～～～～～～～哎，这个人哦～～～～不把时间用在学习上面，就在这些方面花功夫～～～

我的问题提出：

二李书P595页关于正态总体均值与方差的置信区间的表里面，待估参数μ，σ^2位置时，抽样分布为T的双侧置信区间，它写的是
P{|T|≥tα}=α

但是我看很多书上都是些的t(α/2)也就是t那个角标是α/2，不知道是怎么回事呢？是不是错了哦。
一些自己的发现和看法

文登07版601页上面t 0.05(11)=2.201，查电子科技大学应用数学学院所编《概率论与数理统计》P293附录4 t分布表，发现其实只能查t 0.025(11)=2.201，仔细想了想在看看书可以发现所用的t分布表：

而区间分布时计算时候t函数所用的图：

可见，计算的时候其实是算α/2，算得的是上侧分位数，查表的时候根据α/2查就可以了。

其实二李U函数的置信区间都是写的α/2，但T就写的α，感觉还是统一一下比较好。

这是我的一些发现，希望对大家有所帮助。

给PDA安装了好多个新的软件，其中包含了Pocket Mechanic。心想里面有一个磁盘整理的工具，顺便看看能不能把SD卡整理一下。哎，结果提示完成了以后重新启动，竟然发现SD卡内容为空~！！天啊，用Easy Recovery等等软件都不能找回丢失的文件结构。看来是FAT32的两张表都损坏了……可恶的软件啊……！以后再也不敢用了……
