装了一下某人的blogger-large-post-editor的Greasemonkey插件
编辑空间大多了, 哈哈. 用起来真不错:)
哦, homepage可能是这里:

Tex The World 任何网页上写公式的公式都能显示
上面那只是一个主页地址, 提供安装插件的链接和简短的说明. 它实际上是一个利用Greasemonkey的插件, 原理是它发现包含有"[; ;]"的东西就转换为数学形式, 然后以图片的方式显示. 而图片存在thewe.net上(可以通过点击图片右键,属性而看到). 这就带来一个担忧, 如果他的网站挂了, 我的内容就要按照原始的latex文本文件的样子显示了. 不过想想即使那样也没关系, latex本身也基本能看懂的, 而且其移植性依然良好.
安装啥的直接参考原文. 一些基本的操作:
1. 写一个公式: [;\frac{x^2}{4 \pi R^2} ;] TTW会自动转换为公式的样子, 不过有延时
2. 如果想看原始的样子, 双击, 不过双击后两个分号不见了, 但不影响使用; 双击后还可以编辑, 如果是在如google docs等可编辑的环境下; 再次双击就变回去了
另外顺便看到两个蛮有意思的网站:
http://www.latexlab.org/
可以在线编辑和编译latex, 并且显示. 也就相当于一个在线的latex系统.
http://www.twiddla.com/
一个在线的聊天系统, 可以多人语音+文笔聊天, 最值得称道的是有一个白板, 可以多人在上面图画, 这就为多人讨论提供了一个很好的平台.

20081225 死海,沙漠Mitzpe Ramon之旅
2008年12月26日, 一共11人, 包车经历死海, 梅撒达, Mitzpe Ramon然后返回. 虽然目的地是最后的那个地址地带, 但时间不够, 也只在那里待了一个多小时. 家里有PG做后勤, 回来就有热呼呼香喷喷的可口饭菜. 这么舒服的旅行, 是今年第二次. 上一次是和他们去Sde Boker, 有杨飞他们一家的热情周到的后勤. 号称早上8点出发, 人家车9点才到. 不过后来和司机还是相处愉快.

路人甲给我们的两位女士摸泥巴, 号称2 dollars. 其实他也是一个来玩儿的人
这一处是死海的最北边, 海面和沙滩不是很好看, 但实用, 因为泥巴很好...

背后的山比较 壮丽, 是Ein Gedi后面的山. 有人说不像是真的
Ein Gedi的死海海滩, 比刚才那个漂亮许多. 包车就是比坐公交车好, 想到哪儿停就去哪儿. 就是得自己操心时间
很不明白, 其实被盐包着的也是石头. 可是为什么那些沙上不长盐呢?

就当我们赶到的时候, 下午4点钟的样子, visitor centering已经关门了
远处是以色列的望远镜, 比我想像的要大些, 据说还正儿八经地做研究工作滴

旁边是一个攀岩的地方, 几个小铁桩+绳子, 一个工作人员. 我们问多少钱一攀, 说50NIS. 我们还是宁愿多看看风光. 然后告诉他我们只有一个小时, 该看看什么. 他建议就沿着那个边走走, 看看这迷人的景色. 在问一个有很多像木头一样的石头的地方值不值得去的时候, 告诉我们 "Don't waste your time. "
A very nice guy.

看到这个人想起有个故事(事故)是一个人被火车撞了, 问他为什么会被撞的时候, 他说"我只是想知道人最近可以离火车有多远".
