如果要想迅速的得到 Linux 环境中的日志报告信息, Logwatch 是一个很好的工具. 一般的 Linux 系统中可能都默认安装了这个工具.几乎不需要额外的配置就可以简单的用起来. # logwatch --print 这条命令将会把昨天的日志信息简要的打印出来. 比如用户登录失败信息、SSH 登录信息、磁盘空间使用等. 单独查看某个服务,比如 SSH 登录信息: # logwatch --service sshd --print 这条命令可以查看使用说明: # logwatch --help 最新版本的 LogWatch 默认有 70 多种 Log 的配置信息. 如果要对自己的特殊 Log 做监控, 定制也是比较容易的。简单记录一下:

图灵试验是提出的一个关于机器人的著名判断原则。 此原则说:如果一个人使用任意一串问题去询问两个他不能看见的对象:一个是正常思维的人;一个是机器,如果经过若干询问以后他不能得出实质的区别,则他就可以认为该机器业已具备了人的“智慧”(AI)。

Source favicon14:54 Gnome和KDE合作进行市场推广 » Blog on 27th Floor
作为Linux桌面上的两大桌面环境系统,Gnome和KDE已经准备合作进行市场推广活动了,目标是要提升Linux桌面在整个市场上的占有率。

Gnome和KDE之间还有不少故事,怎么有个KDE,而它用了当时并不开放的QT库,于是就有了个Gnome奋起直追。后来争论多了,QT的老板就把搞成了双许可,正式地进入了开源界。这方面争论少了,还有其他无聊的争论,包括人机界面,设计哲学等等。总体上说Gnome显得老派,简单一些,KDE显得现代和华丽一些。一度KDE的开发速度相当快,当然Gnome也在不断地追赶上来。其实这两个互相之间并没有一定的界限,只要运行库在,在G上也一样运行K的程序,反之亦然。

该文作者是KDE的支持者,但他说的一句话非常实在,“如果Gnome从KDE那里夺取20%的份额,它是增长了。但如果Gnome和KDE合起来能夺取10%的桌面市场,那可是一个巨大的进步”。现在法律或开源哲学上的争论少了,其他的争论实际上不算是问题,正是两家合作提升Linux桌面地位的大好时机。同时,也正如作者所说的,在许多地方,两家的程序都要使用同样的基础,比如D-bus,描绘PDF的Poppler和同步PDA的OpenSync等。

从大的环境来说,现在也是非常好的时机。Windows XP是2001年发布的,其实同Win2000区别有限,IE也差不多一样老;其他软件也都是如此,5年来,只见版本号的升级越来越猛,功能上使用方便上其实有多大改进呢?现在许多人还要用Winamp 2.79版,用Acdsee的3.0版,已经说明了许多问题。而正在这一时期内,Linux在普通用户使用的特性上有巨大的进步,变化每天都在发生,虽然这种变化让我的Debian sid系统不是特别稳定,但这种变化仍旧激动人心。想想看,这真的是一个草根阶级的乌合之众的产品啊,而它居然真的能用。

我们已经听说上海地铁上面的显示屏用的是Linux,某些波音飞机座位上也用,Google公司也在桌面上使用。我不是非开源不用的狂热分子,但我相信这个运动就像互联网的中立一样,在促进创新上有着它独特而深刻的作用。Firefox的成功已经刺激了IE7的开发,相信Linux桌面的广泛应用将能激起一些桌面软件的创新。

This past December we quietly made a change to the way people search on Microsoft.com –  Microsoft.com Search is now powered by MSN Search.  This was an exciting project to work on.  We were super jazzed that another team wanted to use our search technology and the Microsoft.com team was equally excited to be upgrading their search to the best Internet Search technology that Microsoft has to offer.  Not only that, but this was not just any team, but rather search for Microsoft.com which is one of top 10 sites on the Internet. The exact position within the top 10 depends on whose numbers you trust most :)

 

The result we think is a far improved search of Microsoft.com content – the satisfaction levels of Microsoft.com search are up and the number of people using search.microsoft.com also increased.  The true judge, however, of whether we are delivering good results is you. So, stop by search.microsoft.com, try out your favorite queries and send us some feedback. 

 

And to boot we shipped this in 58 markets and 31 languages!

Source favicon12:18 Dao bless America: The Congress, China, and counter productivity. » Danwei RSS 1.0

Imagine the following scenario: The American congress passes a bill that makes it practically impossible for American Internet companies to operate and compete in the Chinese market, in attempt to prevent censorship and spread freedom. The new law puts a serious dent in American companies’ ability to operate and compete in the Chinese market. In addition, the few publicly listed Chinese media companies that are not government-owned are also damaged, since most of them went public in the US and must comply with American laws. In the meantime, the Chinese people affirm their belief that America is out to harm them and hinder the development of their economy.

Now try this one: Multinational companies continue to develop services in China. The Chinese public is exposed to more and more information from other countries. China’s communication market becomes more open (slowly…) as more foreign and local money is invested inline with financial - and not political - imperatives. The people of China learn to appreciate the benefits of being a free market economy and just can't have enough...

The Internet develops faster than the laws that govern it. It is important for law makers to respond promptly to the challenges this development brings. But promptly should not mean hysterically, or sanctimoniously. Business is still business, and the market still knows best. New law(s) should draw clear lines on Internet companies’ responsibilities for activities the world over, starting with America. There are plenty of questions that need answering. Below are a few suggestions:

1. Are Internet companies obliged to provide Congress with information on users and usage, even for educational and research purposes?

2. Under what circumstances can American lawmakers request an Internet company to block access to copyrighted material (as it now does)?

3. What is the procedure for companies from other industries, less powerful than the Music Industry, to gain such protection?

4. What are the penalties for American Internet companies that currently block content by request from some European governments? What is the procedure by which these web sites are evaluated and selected?

In any case, China should not be singled out. Fellow Americans, have faith in the market’s wisdom. As the great sage Lao Zi wrote 2,500 years ago:

The Market abides in non-action, yet nothing is left undone. If kings and lords observed this, the ten thousand things would develop naturally. If they still desired to act, they would return to the simplicity of formless substance. Without form there is no desire. Without desire there is tranquility. And in this way all things would be at peace.

"At this time, the hogs of the region ran wild, as they do now in portions of the border states. Some of them were savage, and all, after the manner of swine, were difficult to manage...All the ordinary resources were exhausted in the attempts to get them on board. There was but one alternative, and this Abraham adopted. He actually carried them on board, one by one. His long arms and great strength enabled him to grasp them as in a vise, and to transfer them rapidly one by one from the shore to boat."
It's the early 1800s, and the "Abraham" in question is Abraham Lincoln, whose his superior hog-handling skills are described at length in J.B. McClure's Anecdotes of Abraham Lincoln and Lincoln's Stories, one of the many public domain books you can browse using Google Book Search.

Why are we paging through presidential history? Today is President's Day -- or, to be more accurate, Washington's Birthday. What we now call President's Day was first celebrated on February 22, 1796, commemorating George Washington's birth in 1732. But according the calendar that was in use when Washington was born, his birthday was on the 11th, not the 22nd. When he was a young man of 20, Great Britain and her colonies adopted the modern Gregorian calendar, skipping 11 days and making January, not March, the first month of the year.

That's right – over the course of Washington's life, the times quite literally changed. And to make things even more complicated, in 1971 Congress passed a law making the third Monday in February a holiday commemorating Washington's Birthday, regardless of the date. Since then, historically-minded sorts have suggested it be called "President's Day" to account for Lincoln's February 12 birthday too; today many people associate the third Monday in February with both Washington and Lincoln.

What hasn't changed, of course, is our fascination with the presidency. So on this President's Day we dug up a few gems from the "West Wing" of the Google Books Library Project. Enjoy.

Source favicon02:02 Global searches go to local libraries » Official Google Blog




Recently I’ve been working with libraries on something we’re excited to announce for Google Scholar users. Libraries are fantastic repositories of scholarship, and we want to make them as visible and accessible as possible. We’ve just expanded our Library Search program in Google Scholar to help people around the world find works of their interest in local libraries. That program now includes links to libraries in Hungary, Iceland, Israel, Portugal, Sweden, and Switzerland.



If for example you're a student in Sweden searching Google Scholar for [chemistry], you can click the “Library Search (Sweden)” link underneath the book titled "Principles of polymer chemistry" to see the list of Swedish libraries that hold the book. Then just pay a visit to one of those libraries to reserve it. If you’re outside Sweden, you can activate the Swedish library catalog links from the "Library Links" box in the "Scholar preferences" by searching for Sweden.



If you are a library patron and can't find the books from your library, ask your local library to participate in this program. If you are a librarian and would like to work with us to help users find scholarly literature in your library, please contact us.



We'd like to thank our union catalog partners for helping to make this happen. Here's hoping researchers worldwide will use it to find and build on the amazing collections in the world's libraries.
Source favicon00:04 Apache的后台开发管理系统 » 车东[Blog^2]

上周末和老肖聚会,见到了BugFree的作者刘振飞。BugFree是国内很成功的一套开源Bug跟踪系统;基于PHP/MySQL架构。下午聊的内容很多也是关于网站和软件开发过程一些流程系统。振飞在微软工作过一段时间:而微软内部的Bug Tracking系统Product Studio是他认为最强大的工具之一。BugFree的很多设计如果是借鉴了Product Studio,那么开发者也能从中感受一下微软成功的开发过程。

我个人对开源软件的开发了解多一点。至少在Apache基金会上可以看到他们使用的是以下几个系统的组合:
版本控制:
最早使用的是CVS,目前已经迁移到了SVN上。
Bug/Issue Tracking:
(可选)JIRA(Java)或者BugZilla
文档共享:
Apache目前选择的WIKI平台是:MoinMoin(Python)
邮件列表/归档:
记得以前用的是EyeBrowse(Java)
