Linux上很多好工具要解决的问题（需求）可能别人多年前就也遇到过了，但别人不告诉我的话我就根本不知道它存在。第一次知道MTR还是在几年前和其他公司的工程师沟通XML接口速度问题的时候学到的，当时对方发来这样一个报表：

从搜索前端服务器到Google的XML接口之间的路由，和各个路由点的响应时间（包括最短，最长，平均）及丢包率一目了然。

利用报表中的提示搜索了一下，发现了mtr这个工具，以前需要多个ping和traceroute 命令实现的统计，用mtr集成在了一起。

WinMTR就是MTR工具的Windows窗口客户端，非常适合Windows用户做路由跟踪。

本周 Google 网上论坛中文版和其它十九种语言同时升级，从多年的 beta 测试版终于正式“毕业”！这回 Google 网上论坛添加了不少新功能，使用界面也焕然一新。下面简单介绍一二：

好用、丰富的使用界面
浏览操作比以往清晰简洁得多，现在每个论坛都有一个专有主页，可以自定义外观、选择多样面板色系、上传论坛主图，也能自定字体颜色，由板主决定论坛主页想要出现哪些内容。



自建网页、社区讨论
在 Google 网上论坛内新加了创建网页的功能，您可以在这些网页上发布论坛相关信息，任何成员都可以进行浏览、发帖及添加评论，就像是内嵌了简单易用的博客模块。发表文章时添加图片的功能特别好用，用鼠标轻松移动想要的位置，再点击所需图片大小就搞定了。



最后觉得很值得提提“文件分享”的功能，成员现在可以在论坛中上传、分享文件，如果大家爱拍照，相约都上传图片，论坛几乎也可以当作一个好朋友们共享的网络相册！

试试全新 Google 网上论坛!

an interactive infographic of President Bush's State of the Union address over the years, averaged about 5,000 words, or 34.000 words in total. this means some words appear more frequently than others.

an online application that blends software art & search tools to visualize participants' interests in prevalent streams of information, encouraging browsing & interaction between users in real time.

participants search for words which expand contextually through the use of a lexical database. English nouns, verbs, adjectives & adverbs are organized into floating synonym "seeds," each representing 1 underlying lexical concept. when participants "plant" their interests, each becomes a tree that "grows" over time. each organism's leaves are linked to related streaming RSS feeds, & by interacting with their own & other participants' trees, participants create a contextual timescape in which interests can be seen growing & changing within an environment that endures.
