Clearsilver HTML template system

What is Clearsilver?

Clearsilver is a fast, powerful, and language-neutral HTML template system. In both static content sites and dynamic HTML applications, it provides a separation between presentation code and application logic which makes working with your project easier.

The design of Clearsilver began in 1999, and evolved during its use at onelist.com, egroups.com, and Yahoo! Groups. Today many other projects and websites using it.

Why use Clearsilver?

High Performance and Language Neutral. Because Clearsilver is written as a C-library, and exported to scripting languages like Python, Perl, Java and Ruby via modules, it is extremely fast. This also means you can work with the same template system independent of the language your project is in.

Pluggable Look and Feel. Clearsilver makes it easy to face lift a site by providing a new set of templates. It is possible to easily run more than one look and feel at once, and share components with a base look and feel to reduce maintenance.

Internationalization Support. Clearsilver makes it trivial to support internationlization. You write your templates in your native language and included tools automatically extract and catalog language strings for translation.

Advanced features. Built in support for advanced features such as gzip compression, smart whitespace stripping, parametric macros, online debugging mode, url and javascript string escaping, and more.

How can I learn more?

The Clearsilver documentation explains both the theory of operation for Clearsilver itself, the C-api, and the extension module APIs.

Introduction

The most common use of the hash scripts is to protect login passwords. Here I explain how do this in a way that provides as much security as possible.

Improved Persistent Login Cookie Best Practice

Charles Miller's article, "Persistent Login Cookie Best Practice," describes a relatively secure approach to implementing the familiar "Remember Me" option for web sites. In this article, I propose an improvement that retains all the benefits of that approach but also makes it possible to detect when a persistent login cookie has been stolen and used by an attacker.

网站布局设计的相关分析

Layout Design Requirements Analysis Conduct a layout design requirements analysis before you actually design the layout. This will ensure that you create a website look and feel that not only looks good but hits the mark.

1. Do you have a logo ready? If not, this is a priority as the site style and colors will have to blend with the logo.
2. Do you have a byline ready?
3. What do you want the site to communicate?
4. What do you want a visitor to do on the site? List the sequence of events you would like the visitor to go through.
5. How will you define the success of the site?
6. Who is your target audience?
7. What kind of colors would your target audience like?
8. What kind of graphic style would your target audience like?
9. Are there any competitor sites that you would like to use as a benchmark? What are they doing well on their site?
10. Are there any sites that have a look and feel that is attractive to your target audience? List them.
11. Based on the above criteria have you selected any graphics you would like to use? This is an important step as the layout colors may need to blend with the graphics.
12. Have you got the site plan ready? What will be the main menu and sub menu items?
13. What should be highlighted throughout the site and on the homepage in particular?
14. Will there be a site search? If so, what are the fields and how much space will it occupy?
15. Will there be a newsletter signup or login? Will these fields appear on all pages?
16. Will you have advertising on the site, if so is there a specified area and size to be allocated for this?

用javascript禁止右键等盗取网页内容的技巧

以下是一些网页编程的技巧，这些技巧有破解的方法。
http://topic.csdn.net/t/20061220/16/5244445.html

1. oncontextmenu="window.event.returnValue=false" 将彻底屏蔽鼠标右键
<table oncontextmenu="return(false)"><td>no</table> 可用于Table

2. <body onselectstart="return false"> 取消选取、防止复制

3. onpaste="return false" 不准粘贴

4. oncopy="return false;" oncut="return false;" 防止复制

5. <link rel="Shortcut Icon" href="favicon.ico"> IE地址栏前换成自己的图标

6. <link rel="Bookmark" href="favicon.ico"> 可以在收藏夹中显示出你的图标

7. <input style="ime-mode:disabled"> 关闭输入法

8. 永远都会带着框架
<script language="JavaScript"><!--
if (window == top)top.location.href = "frames.htm"; //frames.htm为框架网页
// --></script>

9. 防止被人frame
<script language="JAVASCRIPT"><!--
if (top.location != self.location)top.location=self.location;
// --></script>

10. 网页将不能被另存为
<noscript><iframe src="">";</iframe></noscript>

11. <input type=button value=查看网页源代码
onclick="window.location = "view-source:"+ "http://www.williamlong.info"">

12.删除时确认
<a href="javascript:if(confirm(" location="boos.asp?&areyou=删除&page=1">删除</a>

13. 取得控件的绝对位置
//Javascript
<script language="Javascript">
function getIE(e){
var t=e.offsetTop;
var l=e.offsetLeft;
while(e=e.offsetParent)
alert("top="+t+"/nleft="+l);
}
</script>

//VBScript
<script language="VBScript"><!--
function getIE()
dim t,l,a,b
set a=document.all.img1
t=document.all.img1.offsetTop
l=document.all.img1.offsetLeft
while a.tagName<>"BODY"
set a = a.offsetParent
t=t+a.offsetTop
l=l+a.offsetLeft
wend
msgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置"
end function
--></script>

14. 光标是停在文本框文字的最后
<script language="javascript">
function cc()
{
var e = event.srcElement;
var r =e.createTextRange();
r.moveStart("character",e.value.length);
r.collapse(true);
r.select();
}
</script>
<input type="text" name="text1" value="123" onfocus="cc()">

15. 判断上一页的来源
javascript:
document.referrer

破解的方法，以上的方法都是利用javascript的相关函数取代一些默认操作的反应，那么如果禁止javascript，整个网页就是不设防的了，你想怎么拷贝就怎么拷贝。

这个网站存储了大量网站的历史网页，更新的周期为每一个月一次，将每一个月的网站首页等都保存下来。在这里你可以查看几年之前某个网站，比如sina或者google是什么样子，他们做了哪些修改等等。

怎样修改google的广告？NO！

最好的建议是不要修改，因为Google的规定里说了，不能对广告代码做任何方式的修改。

今天收到了google Adsense的来信，说网站上的搜索框，修改了原来的代码。

为了检索方便，我在google原来的搜索框中添加了默认的关键字，修改了搜索按钮的名字，还有的搜索框，我把google的图标定向到了我们网站的搜索页面。所有的这些都给用户提供了方便，因为用户可以省去输入关键字的麻烦，但是所有这些都违反了Google Adsense的规定。

不过还好，google adsense说给72小时处理，因为有的广告上会马上取消你的帐号，不再让你登录了，你之前的所有收入也都会蒸发掉。

怎样做对google来说比较友好的网页呢，google提供了很多建议，如下面的链接就给出了google给网站管理员的建议。

Chart API

前段时间找到了一个JavaScript的Chart绘图表的代码库，叫做PlotKit

PlotKit is a Chart and Graph Plotting Library for Javascript. It has support for HTML Canvas and also SVG via Adobe SVG Viewer and native browser support.

PlotKit is fully documented and there is a quick tutorial to get you started.

PlotKit is a complete rewrite of CanvasGraph. It is better structured and supported.

这里也有一个画图表的JavaScript Diagram Builder
http://www.lutanho.net/diagram/

The JavaScript Diagram Builder v. 3.3 is a library of some objects and functions, which can help you to display a coordinate diagram (resp. a chart or graph) in your webpage in an easy way. The file 'diagram.js' contains all the necessary objects and functions. This file must be included in the header of your webpage:

今天发现原来google也提供了Chart API http://code.google.com/apis/chart/

而且已经有了中文版的文档，http://labs.cloudream.name/google/chart/api.html
还有图形化生成图片URL代码的网站
http://charts.hohli.com/

还有一个也是在code.google中的JavaScript的Plot库，http://code.google.com/p/flot/

Flot is a pure Javascript plotting library for jQuery. It produces graphical plots of arbitrary datasets on-the-fly client-side.

The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming.

Although Flot is easy to use, it is also advanced enough to be suitable for Web 2.0 data mining/business intelligence purposes which is its original application.

The plugin is targeting all newer browsers. If you find a problem, please report it. Drawing is done with the tag introduced by Safari and now available on all major browsers, except Internet Explorer where the excanvas Javascript emulation helper is used.

这个库的例子包括官方的例子
http://people.iola.dk/olau/flot/examples/
使用Flot的网站：http://aegis.ucolick.org/products/MTR/explore.html

今天又查了一下YUI，Yahoo提供的免费的一个库，里面也有不错的Chart Control，生成的是swf的图片，有较好的互动效果，如鼠标指的位置显示相应的数据说明。
这里是一个数据说明，当然，缺点是需要用户安装了swf才能看到你的图片结果。

Java Web层框架比较—— 比较JSF、Spring MVC、Stripes、Struts 2、Tapestry和Wicket2007年11月22日星期四 上午 10:58 【译者按】这是Matt Raible在今年6月24-27号召开的JA-SIG夏季会议上所作的主题演讲，Matt从众多方面对Java Web层框架做了一个全面、深入的比较。笔者认为这是一份及时的文档，它对开发者如何判定一个Web层框架的好坏、如何选择适合自己项目的框架有极大的指导作用。本文是对Matt Raible演讲稿的整理归纳。
【作者介绍】Matt Raible，开源框架AppFuse的发起者、主要开发者；《Professional JSP 2.0》、《Spring Live》等书的作者；众多会议的演讲者，MySQL User Conference, ApacheCon, ApacheCon EU等；现任Raible Designs的CEO。

首先，Matt以自己的实践经验，指出了Java Web层框架——JSF、Spring MVC、Stripes、Struts 2、Tapestry和Wicket他们各自的优、缺点：
JSF
优点：
Java EE标准，这意味着有很大的市场需求和更多的工作机会
上手快速并且相对容易
有大量可用的组件库
缺点：
大量的JSP标签
对REST和安全支持不好
没有一个统一的实现。既有SUN的实现，又有Apache的实现——MyFaces。

Spring MVC
优点：
对覆盖绑定（overriding binding）、验证（validation）等提供生命周期管理
与许多表示层技术/框架无缝集成：JSP/JSTL、Tiles、Velocity、FreeMarker、Excel、XSL、PDF等
便于测试——归功于IoC
缺点：
大量的XML配置文件
太过灵活——没有公共的父控制器
没有内置的Ajax支持

Stripes
优点：
不需要书写XML配置文件
良好的学习文档
社区成员很热心
缺点：
社区比较小
不如其他的项目活跃
ActionBean里面的URL是硬编码的

Struts 2
优点：
架构简单——易于扩展
标记库很容易利用FreeMarker或者Velocity来定制
基于控制器或者基于页面的导航
缺点：
文档组织得很差
对新特征过分关注
通过Google搜索到的大多是Struts 1.x的文档

Tapestry
优点：
一旦学会它，将极大地提高生产率
HTML模板——对页面设计师非常有利
每出一个新版本，都会有大量的创新
缺点：
文档过于概念性，不够实用
学习曲线陡峭
发行周期长——每年都有较大的升级

Wicket
优点：
对Java开发者有利（不是Web开发者）
页面和显示绑定紧密
社区活跃——有来自创建者的支持
缺点：
HTML模板和Java代码紧挨着
需要对OO有较好的理解
Wicket逻辑——什么都用Java搞定

接着，Matt通过采访这些框架的作者，与他们讨论各种开源的Java Web框架，并且突出各个框架的长处、听取框架作者对其他框架的看法，希望借此了解这些框架的未来发展方向。

下列是一些被采访者：
JSF, Jacob Hookom
RIFE, Geert Bevin
Seam, Gavin King
Spring MVC, Rob Harrop
Spring Web Flow, Rob Harrop and Keith Donald
Stripes, Tim Fennell
Struts 1, Don Brown
Tapestry, Howard Lewis Ship
Trails, Chris Nelson
Struts 2, Patrick Lightbody
Wicket, Eelco Hillenius

Matt对采访做了如下总结：
JSF:
如果你想让web应用具有类似桌面程序的功能性，那么JSF的标准规范和大量第三方组件库的支持值得你 信赖。
Spring MVC:
综合了许多不同的技术，这使得它可以被广泛地应用到不同类型的项目中去；它可以被当作web应用开发的一个基础平台。
Stripes:
可以被应用到存在大量复杂数据交互的程序中；有强大的类型转换、绑定和验证功能；可以使管理大的复杂表单以及直接映射它们到域对象变得简单……
Tapestry:
在中到大型项目中，表现突出（当然，你也可以只把它应用到单个页面上），在这些项目中，你可以通过简单地创建新的组件起到杠杆作用。
Struts 2:
通常更适合于那些希望可以真正开始做事并且愿意花费大量时间来学习他们使用的开源工具的小项目组。Struts 2的目标不是那些更喜欢拖放式开发的“扶手椅程序员”。
Wicket:
非常适合于这样的内/外部网应用：UI很复杂并且你希望可以充分利用你的开发者资源。

上面的总结，基本是突出了各个框架的长处。然而，哪些又是他们不好的地方呢？

Matt提出了评价一个框架好坏与否的标准：
Ajax支持 是不是内置了？是否便于使用？
书签能力 用户能否将某个页面收藏起来并且可以方便地返回到该页面？
验证 使用是否简单？是否支持客户端（JavaScript）验证？
可测试性 脱离容器测试控制器，是否足够简单？
提交和重定向 框架如何处理重复提交问题？
国际化 如何支持国际化？控制器利用国际化信息，是否容易？
页面修饰 框架支持哪种类型的页面修饰/组成机制？
社区和技术支持 提出问题，能否被快速地、恭敬地回答？
开发工具 是否有支持这个框架的好的工具，尤其是IDE？
市场需求 学习了这个框架，它能否帮你找到份工作？
岗位数量 在dice.com和indeed.com上，对这个框架技能的需求如何？

笔者认为这个评价标准，值得大家借鉴。

然后，Matt按照这些评价标准，对各个框架做了以下阐述：
Ajax支持
JSF：没有内置的Ajax支持，需要使用ICEfaces和Ajax4JSF
Stripes：没有对应的类库，支持流输出
Struts 2：内置Dojo，有用于GWT和JSON的插件
Spring MVC：没有对应的类库，需要使用DWR和Spring MVC扩展
Tapestry：Tapestry 4.1中，有内置的Dojo
Wicket：有Dojo和Script.aculo.us支持

书签能力
JSF：可以任意提交——URL甚至不被考虑
Stripes：使用约定，但是你可以不加理会
Struts 2：有命名空间的概念，这使得收藏某个页面并返回变得容易
Spring MVC：允许完全的URL控制
Tapestry：依然存在一些丑陋的URL
Wicket：允许装配（mount）页面/URL

验证
JSF：默认的国际化信息丑陋，但是配置简单
Stripes和Wicket：用Java类进行验证——不支持客户端验证
Struts 2：使用OGNL完成强大的表达式验证功能；只有在Action上指定了规则，才支持客户端验证。
Spring MVC：允许你使用公共验证器——这是一种成熟的解决方案
Tapestry：有健壮的验证功能——不需自定义就有漂亮的国际化信息

可测试性
Spring MVC和Struts 2：允许利用mocks（例如EasyMock、jMock和Spring Mocks）简单地进行测试
Tapestry：测试困难，因为页面类被抽象、具体类被简化
JSF：页面类可以方便地被测试，实际上很像Struts 2 中的actions
Wicket：有WicketTester——一个强大的解决方案
Stripes：有Servlet API Mocks和MockRoundtrip

提交和重定向
解决重复提交问题的最简单方法是：在提交后重定向
Spring MVC：允许你将参数加到重定向URL上
Stripes、Tapestry和Wicket：有“flash式”的支持
Struts 2：需要一个自定义的解决方案
JSF：需要一个自定义的解决方案，国际化信息很难加入到页面bean中

国际化
JSTL的标签使国际化变得简单；如何将国际化信息放到控制器类中，还没有一个统一的标准。
Stripes、Spring MVC和JSF：每个地区使用一个资源绑定文件
Struts 2、Tapestry和Wicket：提倡把每个页面/action用到的资源文件分开
JSF：需要在每个页面上定义资源绑定信息
Tapestry：标签比较可怕

页面修饰
Tiles能够用于Struts 2、Spring MVC和JSF中；需要对每个页面进行配置。
SiteMesh能够用于所有的这些框架中（不推荐在JSF、Tapestry或者Wicket中使用）；在设置完成后， 只需要很少的维护。

开发工具
Spring MVC：Spring IDE，但是只做XML校验，不是一个UI/web工具
Struts 2：Eclipse
Tapestry：Spindle，对编码者非常有利
JSF：众多IDE支持，并且做得越来越好
Stripes和Wicket：没有任何官方工具
NetBeans目前支持Struts *、JSF（+Facelets）、Tapestry和Wicket，尚不支持Stripes和Spring MVC


市场需求
Struts 1：需求依然很大并且被广泛使用
Spring MVC：越来越受关注，但大部分是因为Spring框架的一些其他特征
JSF：很快地变得流行起来
Struts 2：正在获得地盘，但是相关的工作机会很少
Tapestry：在过去的数年里，受欢迎程度不断增加
Wicket和Stripes：还是未知数

通过以上的比较，我想大家对在自己的项目中应该选择哪种Web层框架，应该有了更清醒的认识。

微软的宣讲

很多天前在清华开了微软的宣讲，来了几个头头，不过没有开复。
里面几个人，特别是那几个讲台湾普通话的感觉都很有魅力，而一个清华管搜索的感觉特没劲的一个人，说话一点意思都没有。
管人事的大哥也很有趣，说如果你很喜欢你的工作，每天100%的工作时间都是在做自己喜欢做的时，为什么还需要20%的时间干别的事？（这个暗讽谷歌，还有个暗讽百度的，我记性差，过了这么几天就给忘了，总之讽刺得很有才。）

去参加了微软的笔试，才发现与计算机系的学生的差距那么大，什么数据结构、算法分析、编译原理等等都不知道，这类的题都是瞎蒙。最终，没有得到被微软的人当面鄙视的机会。

什么是“五险一金”

之前听说过三险一金，今天参加了招聘会，提到了五险一金。上网查了一下，是这样解释的：

《中华人民共和国劳动法》第九章第七十三条规定“劳动者在下列情形下，依法享受社会保险待遇：1、退休，2、患病、负伤，3、因工伤残或者患职业病，4、失业，5、生育。”。
因此，“五险”包括养老保险、医疗保险、工伤保险、失业保险和生育保险，其中养老保险、医疗保险和失业保险，这三种险是由用人单位和个人共同缴纳保费，工伤保险和生育保险完全是由用人单位承担的，个人不需要缴纳。
“一金”指住房公积金。
《国务院关于修改〈住房公积金管理条例〉的决定》第一条中将住房公积金定义为“国家机关、国有企业、城镇集体企业、外商投资企业、城镇私营企业及其他城镇企业、事业单位、民办非企业单位、社会团体及其在职职工缴存的长期住房储金”，住房公积金由用人单位和个人共同缴纳。

四险一金和三险一金都不是全的。

KooXoo的技术

今天参加了KooXoo的宣讲会，KooXoo的CEO陈华和技术总监陈欣也参加了。
会前我去厕所，出来的时候还和陈欣擦肩而过。我还以为是个来找工作的博士生。
后来介绍了一下自己的经历和公司的技术，说话挺风趣的。他在百度和微软都工作过，之所以来到刚刚成立的酷讯是因为，在这里他能够得到更多，决定更多；而在百度，股价和自己的收入似乎和自己的努力没有什么关系（这一点，今天刚看到了google的黑板报里面的两位头头给员工的信，里面有对这方面的考虑）。

陈华不知道有没有三十岁，大概和我年龄差不多（在清华熬了9年，自己已经很老了，发现周围都是年轻人）。陈华是所有招聘人员里除了HR之外唯一一个穿着崭新西服，打着还有些发亮的领带的人。陈华站着的时候，两只手垂在两边，对一个没有将军肚的人来说稍显别扭。

KooXoo的HR姐姐（应该是MM）临场发挥的能力可能较差，介绍酷讯的生活工作和待遇的时候基本上都是照着幻灯片念下去，而且对几位公司的头头太过崇拜，显得不够谦虚。不过回答问题时的气质还不错。

酷讯的待遇讲得确实不错，包括股票期权（公司的目标是五年内上市）、五险一补、带薪病假、免费早餐、灵活的上班时间和随意的着装等等。（户口也有尽力争取的承诺。）

最后是问答阶段，有个气鼓鼓的女生一连问了好多问题，不过问题的质量还可以。关于公司的盈利模式和盈利状况，陈华的回答得很直接：还在探索，还没有盈利。

关于技术：酷讯说了很多垂直搜索的细节的技术，比如没有模板的抓取（这个显然是以牺牲数据准确性为代价的）、ajax更新网页的抓取（这个是一个清华的计算机系的人做的，不知道是不是模拟浏览器以抓取数据，这样的数据包括水木社区的内容）、冒泡搜索（这个实际上并不是什么很玄乎的东西，实际上网页浏览的人可能只有中国才有那么多人有闲工夫开着浏览器等新的数据被抓上来）。

关于数据的质量，看了酷讯的招聘信息后发现，他们还有专门打电话核实房源的人，不过在中国这样的信息混乱到处可能是骗子的时候，人肉搜索似乎有其存在的必要性。不过，提到了电话与房源或者火车票的起始地点不在同一个地方的可能是骗子的想法倒是很新颖。

Transform XML and apply XSLT in C#

I searched the internet and found two articles:
first from MSDN

using System;
using System.Xml;
using System.Xml.Xsl;
namespace XSLTransformation
{
   /// Summary description for Class1.
   class Class1
   {
       static void Main(string[] args)
       {
           XslTransform myXslTransform;
           myXslTransform = new XslTransform();
           myXslTransform.Load("books.xsl");
           myXslTransform.Transform("books.xml", "ISBNBookList.xml");

       }
   }
}

The second is from CodeProject

This one is long and you should check it yourself.

学习的三个途径：Three ways to learn

参加了一个宣讲会，里面介绍了HR的PPT上面有个关于学习的说法：
10%的课堂学习
20%的边教边学
70%的边干边学

嗯，有点意思。

Get the visitor's IP address

http://www.developerfusion.co.uk/show/1626/
AuthorJames Crowley

Whenever a browser sends a request for a page, it also sends a number of other headers to the script, containing information such as the browser type. It also includes information such as the visitors IP address. This can be particularly useful when creating an online security scan, or logging their IP address in an online forum.

There are two server variables of interest; REMOTE_ADDR and HTTP_X_FORWARDED_FOR. As many visitors access the internet via a third party (ie their ISP), REMOTE_ADDR does not always contain their IP address... it contains their ISP's address. If this is the case, most browsers then store the users IP address in the HTTP_X_FORWARDED_FOR variable. So, first, we check HTTP_X_FORWARDED_FOR, and then if that is empty, we try REMOTE_ADDR instead:

Dim sIPAddress

sIPAddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If sIPAddress="" Then sIPAddress = Request.ServerVariables("REMOTE_ADDR")

One other thing worth bearing in mind. If the user also accesses the internet via a Proxy server, then HTTP_X_FORWARDED_FOR will contain the Proxy's IP address. If this is the case, there is no way to get the users 'real' IP address.

怎样得到访问者的IP地址，比如你想根据IP地址的不同为用户显示不同的内容或者做用户统计。这个量通常存储在ReMOTE_ADDR中，如果这里面没有数据，那么就在HTTP_X_FORWARDED_FOR中。

可以使用下面的函数得到IPAddress

Function IPAddress()
IPAddress = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If IPAddress="" Then IPAddress = Request.ServerVariables("REMOTE_ADDR")
End Function

使用下面的函数隐藏最后一位

Function IPAddress2(IPAddress)
IF IsNull(IPAddress) Then
IPAddress2=""
Else
IPAddress2=Left(IPAddress,InStrRev(IPAddress,"."))&"*"
End IF
End Function

A Visual Explanation of SQL Joins

原文发表于2007年10月11日的http://www.codinghorror.com/blog/

A Visual Explanation of SQL Joins

I thought Ligaya Turmelle's post on SQL joins was a great primer for novice developers. Since SQL joins appear to be set-based, the use of Venn diagrams to explain them seems, at first blush, to be a natural fit. However, like the commenters to her post, I found that the Venn diagrams didn't quite match the SQL join syntax reality in my testing.

I love the concept, though, so let's see if we can make it work. Assume we have the following two tables. Table A is on the left, and Table B is on the right. We'll populate them with four records each.

id name       id  name
-- ----       --  ----
1  Pirate     1   Rutabaga
2  Monkey     2   Pirate
3  Ninja      3   Darth Vader
4  Spaghetti  4   Ninja

Let's join these tables by the name field in a few different ways and see if we can get a conceptual match to those nifty Venn diagrams.

SELECT * FROM TableA INNER JOIN TableB ON TableA.name = TableB.name id name id name -- ---- -- ---- 1 Pirate 2 Pirate 3 Ninja 4 Ninja Inner join produces only the set of records that match in both Table A and Table B.
SELECT * FROM TableA FULL OUTER JOIN TableB ON TableA.name = TableB.name id name id name -- ---- -- ---- 1 Pirate 2 Pirate 2 Monkey null null 3 Ninja 4 Ninja 4 Spaghetti null null null null 1 Rutabaga null null 3 Darth Vader Full outer join produces the set of all records in Table A and Table B, with matching records from both sides where available. If there is no match, the missing side will contain null.
SELECT * FROM TableA LEFT OUTER JOIN TableB ON TableA.name = TableB.name id name id name -- ---- -- ---- 1 Pirate 2 Pirate 2 Monkey null null 3 Ninja 4 Ninja 4 Spaghetti null null Left outer join produces a complete set of records from Table A, with the matching records (where available) in Table B. If there is no match, the right side will contain null.
SELECT * FROM TableA LEFT OUTER JOIN TableB ON TableA.name = TableB.name WHERE TableB.id IS null id name id name -- ---- -- ---- 2 Monkey null null 4 Spaghetti null null To produce the set of records only in Table A, but not in Table B, we perform the same left outer join, then exclude the records we don't want from the right side via a where clause.
SELECT * FROM TableA FULL OUTER JOIN TableB ON TableA.name = TableB.name WHERE TableA.id IS null OR TableB.id IS null id name id name -- ---- -- ---- 2 Monkey null null 4 Spaghetti null null null null 1 Rutabaga null null 3 Darth Vader To produce the set of records unique to Table A and Table B, we perform the same full outer join, then exclude the records we don't want from both sides via a where clause.

There's also a cartesian product or cross join, which as far as I can tell, can't be expressed as a Venn diagram:

SELECT * FROM TableA
CROSS JOIN TableB

This joins "everything to everything", resulting in 4 x 4 = 16 rows, far more than we had in the original sets. If you do the math, you can see why this is a very dangerous join to run against large tables.

网站安全快速检查清单

这里是从http://www.googlechinawebmaster.com/转来的一篇文章

网站安全快速检查清单

2007年10月5日 上午 10:01:00

发表者： Nathan Johns, 搜索质量组

原文：Quick security checklist for webmasters
发表于： 2007年9月18日，星期二，12:34AM

最近几个月，失密网站的数量明显增多。一种解释是黑客黑掉了一些网站来发布恶意软件或制造垃圾搜索结果。不论是何原因，这是我们为站长们提供一些网站安全方面的小技巧的好时机。

免责声明：虽然我们收集了很多小贴士以及链接，我们也鼓励管理员“请在家中尝试以下方法”，但是这绝不是一个保护你网站安全的完整清单。我们希望它有帮助，但我们也建议您要对网站安全进行更深入的研究。

• 检查你的服务器配置

在Apache的网站上有一些安全配置技巧， 微软也有一个IIS技术资源中心。其中的主要技巧包括目录权限信息，服务器端包括认证和加密信息。

• 总是使用最新的软件更新和补丁
  

人们经常犯的的错误是在自己的网站上安装一个论坛或博客软件，然后就再也不管了。就像你的车总是要保养一样，保持对你安装的任何软件的最新更新也是很重要的。需要一些小贴士？Mark Blair的博客上有一些很好的，包括为你网站上所有的软件和插件列个清单，并跟踪版本号和更新历史。他还建议利用任何软件开发者网站提供的feed。

• 经常留意你的日志文件
  

养成这个习惯有很多好处，其中之一就是安全性的增加。你可能会对你的发现有些惊讶。

• 检查你的网站，看看有没有常见漏洞
  

避免存在有开放权限的目录。这几乎就像把你家的前门敞开，门前的垫子上写着“来吧，请随意！” 你也要检查任何xss（跨站点脚本）和SQL注入漏洞。最后，选择好密码。你可以依循Gmail支持中心的一个很好的指南，它会帮助你选择一个密码。

• 警惕第三方内容提供商
  

如 果你正考虑安装一个由第三方提供的应用软件，例如一个控件，计数器，广告网络，或网络统计服务，一定要非常小心。虽然网络上有很多非常好的第三方内容，有 些提供商也可 能利用这些应用软件来干坏事，例如对你的访客有危险的脚本。要确保应用软件来自有信誉的提供者。他们有一个合法网站吗？他们提供技术支持吗？他们有联系信 息吗？有其他管理员用过该软件吗？

• 尝试在Google上用site:搜索来看看Google索引了你的什么网页
  

这看似有点明显，但它经常被忽视。对你的网站做一个例检并确保一切正常总是有好处的。不熟悉site:搜索操作?它是一个让你只在一个具体网站上搜索的方法。举例说，搜索 site:googleblog.blogspot.com只会返回谷歌官方（英文）博客的结果。

• 使用谷歌的站长工具
  

谷歌的站长工具是免费的。它还有各种各样的好功能。譬如，它有关于你的网站的状态数据和管理Googlebot抓取您网站的工具。另一个亮点是，如果谷歌认为你的网站已被攻陷并被放置了恶意软件， 我们的站长控制台会显示更详细的信息，如一些有害网址的样本。一旦你认为恶意软件已经被删除，你可以通过站长工具来要求重新审查。

• 使用安全协议
  

数据传输应该用SSH和SFTP，而不是象telnet或FTP的纯文本协议。 SSH和SFTP会加密，也就更安全。关于这个和其他许多有用的小技巧，请参考StopBadware.org的清除和保护你的网站的小技巧。

• 阅读谷歌在线安全博客
  

这个博客上有很多很好的关于线上安全的内容并有指向有用资源的链接。建议你把它加到你的Google Reader Feeds。:)

• 从您的网站寄存服务公司寻求支持
  

许多网站寄存服务公司都有技术服务组。如果你觉得有点儿不对劲，或者仅仅想确保你的网站是好的，你可以访问他们的网站或给他们打一个电话。

我们希望你能从我们的小贴士中发现有用的信息。如果您想分享你自己的技巧，请为这篇文章发表评论，或者在谷歌站长帮助小组开一个讨论。立即动手，让你的网站更安全！

VBScript:object required error

Dim a
Set a="asdfa"
语句有时会遇到这样的错误：

Microsoft VBScript runtime エラー '800a01a8'

Object required: '[string: "asdfa"]'

/yourfile.asp, 行 36

解决方法：
这里不需要使用set，赋值时直接用等号就可以了，如果是指定对象才用set.

Dim a
a="asfda"

HideLinks - Shorten long web addresses and hide bookmarks with a password! favorites-links. export-favorites. add-favorites. favourites-manager.

这个网站可以将某个网页的地址转化为一个较短的加了密URL地址，通过www.hidelinks.com跳转到原来的网页。有什么用呢，这样你就可以将某个网页收藏，而别人却不知道这个网页的真正的地址，除非知道密码，所以你可以收藏很多不想让别人知道的网页地址。

Copy File in C/C++

How to copy file in C/C++ or rename a file?
1) Use System command.
system("copy sourcefile.txt destinyfile.txt");

2)
#include
#include

int main() {
std::ifstream infile("src.dat", std::ios_base::binary);
std::ofstream outfile("dest.dat", std::ios_base::binary);
outfile << infile.rdbuf(); }

3)

使用copy函数，file.copy("fromfile.txt","toFile.txt");

4) Simple C/C++ Perfometer: Copying Files (Versions 4.x)

上面是最详细的使用各种方法进行文件拷贝的介绍，以及速度测试。

In Class defined Function are inline function

今天看 《The C++ Programming Language》,提到一个以前没有注意的问题，就是将函数的定义放在类的定义中，没有inline关键字，但是仍然为inline函数，所以只能将短小的经常使用的函数放在类的定义中。

另外，如果inline函数的调用超过上万次，可能会导致编译出来的代码过长，程序体积过大。

MoinMoin Wiki 的源代码加亮功能

要像使用{{{#!LanguageName LanguageSource}}}来加亮里面的语法，需要到MoinMoinWiki的网站上下载一些py文件。
http://moinmoin.wikiwikiweb.de/ParserMarket

找到文件后（如找到sql.py, xml.py等等），将这些py文件拷贝到你的wiki目录下的data/plugin/parser
目录下，就可以了。

uncaught exception: Permission denied to call method XMLHttpRequest.open

使用Ajax进行请求时得到这样的错误，浏览器为Firefox。
这里有一个解释：
http://www.captain.at/howto-ajax-permission-denied-xmlhttprequest.php

If you want to do cross-domain scripting with XMLHttpRequest, e.g. fetching data from a remote location but you're on a local page or local XUL application (file:///), you need to tell Mozilla/Firefox about that, otherwise you get the infamous error:

Error: uncaught exception: Permission denied to call method XMLHttpRequest.open

意思就是说请求外部的一个url的时候，浏览器需要特别的授权。
xmlHttpRequest is not "allowed" to connect to a different website from the one it is running on.

其它的页面也有一些解决方案，就是将浏览器的安全等级降低。
http://blog.monstuff.com/archives/000262.html

但是这个问题实际上无法解决，如果你就是想请求外部的某个连接返回的地址的话。

JavaScript Error : form submit is not a function under Firefox

The main reason for this error is that the firefox browser is confused.
There must be an input named "submit":

name="submit" value="1">

so that the browser doesnot know it should action on this button or submit the form.

SOLUTION:
change the input's name into something else.

A MegaTokyo RSS Feed Reader (ASP)
by John Peterson

The other day, one of my favorite online comics, MegaTokyo, finally added an RSS feed. Being the MT junkie that I am, I instantly decided that I needed to put this on my start page.

If you're not familiar with RSS, you might find XML Files's RSS section helpful.

As I've mentioned in the past, because I spend so much of my time in a browser, I've taken the time to build my own customized start page that runs on my local web server. It contains a number of things that I use on a fairly regular basis. These include search forms for my favorite search engines, a page containing dns, ip addresses, and connection details for my servers, links to sites I visit daily, links to my router config screens, etc. So what's the point? The point is that now it's going to contain the latest headlines from MegaTokyo as well.
Why MegaTokyo?

There are RSS feeds for everything these days. So why did it take me this long to write an ASP script to read one? Simple... because I'm lazy and until now there wasn't a feed I wanted on my homepage. Why did I use classic ASP instead of ASP.NET? Two reasons: there are already scripts everywhere to do this in ASP.NET, and my homepage is still running on classic ASP. I know I could easily convert it, but I think the answer to the first question already adequately covers why I haven't.

To be honest, there's nothing special about the code... it'll work with most any RSS feed. I've done a few things specific to MegaTokyo's feed (like replacing
s with
s for XHTML compliance), but there's really no reason you couldn't use this script with any RSS feed. In fact, we use a very similar script on our homepage to pull in the headlines from DevX's .NET feed. (Before you write, asking me to add headlines for your site, please note that DevX is also owned by Jupitermedia).

kwRSS: RSS Reader & Writer

The main aim of this project is to allow easy manipulation of RSS (RDF Site Summary) files, both writing and reading them, in 2 version, the widely used version 0.91 (in FullXML, PHP-nuke, etc), and the latest official version 1.0 (based on RDF specifications by W3C).

kwRSS became popular as it seems to be the only free RSS reader/writer for ASP, it has also been mention in the book "The ABC of Seo" by David George (Lulu Press, February 28, 2005).

kwRSS is made up of 2 ASP classes, one for the reader and the other for the writer. Information on how to used them are in the provided example files in the zip file, easy to understand.

The RSS feeds that are generated are RSS/RDF complaint, and a proof is by clicking on the following link to validate the test feed:

iText.NET - Free PDF Library for .NET Framework

http://www.ujihara.jp/iTextdotNET/en/index.html

What's iText .NET

iText, Java-PDF library, is developed by Mr. Bruno Lowagie, Mr. Paulo Soares and co-workes. This library is available under MPL/LGPL license. iText .NET is iText poring on .NET Framework by J#.

In addition, GNU Classpath, JUnit, and Xerces are ported on the way. Refer iText.NET as an example of transferring Java to .NET.

There are several iText port available. Try iTextSharp and original iText on IKVM along with iText.NET. I recommend you to use iTextSharp for a new .NET project. I'm also using iTextSharp.

• iText --- Java
• iTextSharp --- C#
• IKVM --- Java on .NET or Mono
• pdftk --- gcj

在ASP中得到网址域名的命令

get host name by asp's visual basic functions.

host=lcase(request.servervariables("HTTP_HOST"))

这样就可以得到HOST名字，例如 www.google.com 或者 localhost:8080

我这样做是为了在网站中的不同二级域名下使用google maps api。
有了上面的函数就可以根据二级域名选择不同的google maps api的key了。

RewriteRule ISAPI_rewrite URL rewriting Reference

http://www.isapirewrite.com/docs/

Here is part of the docs

Introduction

ISAPI_Rewrite is a powerful regular expressions-based URL manipulation engine. It acts mostly like Apache's mod_Rewrite, but it is designed especially for Microsoft Internet Information Server and Microsoft Security and Acceleration Server 2004. If you ever wanted to change your web site's URL scheme, this product is for you!

Some key benefits of ISAPI_Rewrite:

* Speed

ISAPI_Rewrite is extremely fast and highly scalable solution. It is written by using only pure C/C++ code, Win32 API and ISAPI. It uses intelligent configuration cache mechanism. All work is done just in one stage and there are no recursively requests or any other operations that may take a long time.
* Security

ISAPI_Rewrite is designed for operation in a shared environment. It can serve as many sites as you have. ISP and hosting providers can safely permit their users to configure ISAPI_Rewrite and be sure that any configuration changes will affect only local user's environment. ISAPI_Rewrite can even solve many security problems, for example, block an access to some folders or file extensions or create more complex rules.
* Power

Flexibility and power of ISAPI_Rewrite come from its regular expression nature. With regular expressions you don't need to write a thousands check strings. The comparison and replace of URLs can be done with a few string patterns. So, ISAPI_Rewrite can do many things that cannot be done using other solutions available for IIS. See examples section for more information.

Here is something about
Create Dynamic Sub-domains in (Windows/IIS) using isapi_rewrite

Introduction

Do you have a web site that is hosted on a Windows Server that has been growing and now it makes more sense to redefine the architecture and separate that web site into subdomains? In this article, we will be discussing two methods of setting this up. And later in the article, we'll provide you with a comparison analysis and our conclusions.

Requirements

1. Ability to update DNS records
2. IIS web server admin access
3. isapi_rewrite component (for Solution 2)

Solution 1: Create Multiple IIS Web Sites

Setup DNS Server

You have two options. Since you probably have a limited number of subdomains to manage, you can either list them out individually or just use a wildcard.

Wildcard method: Add the following entry into your DNS server and change the domain and IP address accordingly.

*.example.com IN A 1.2.3.4

Declare manually: Add an entry for each of the subdomains.

sub1.example.com IN A 1.2.3.4
sub2.example.com IN A 1.2.3.4
sub3.example.com IN A 1.2.3.4

Setup the Web Server

First make sure you have created a root directory for each of the subdomains, as if you are working with a new web site. Your directory might look like the following:

d:\inetpub\wwwroot\example.com\sub1\
d:\inetpub\wwwroot\example.com\sub2\
d:\inetpub\wwwroot\example.com\sub3\
d:\inetpub\wwwroot\example.com\js\
d:\inetpub\wwwroot\example.com\css\
d:\inetpub\wwwroot\example.com\img\

Next, we create a web site for each of the subdomains. Let's create the first one and you can repeat this for all others.

* Open IIS Management Console
* Click on the Web Sites folder and select New : Web Site
* Click on Next to continue.
* Enter the description for your site then click Next. An example would be: sub1.example.com.
* On the IP Address and Port Setting, enter sub1.example.com into the Host header for this Web site field.
* On the next page, enter the path d:\inetpub\wwwroot\example.com\sub1\
* On the next page, select your options click Next and you're done.

Now here's the fun part. Since you have created a new site for each subdomain, but there are files that are shared across them, such as javascript, style sheets, and images, what you could do is to create a virtual directory to link them to each of the web sites. Here's how you do it.

* Right click on the subdomain you have just created in IIS Management Console and select New : Virtual Directory
* As an example we'll share the style sheet folder (css). Click on Next and enter css in the Alias field.
* Enter the path d:\inetpub\wwwroot\example.com\css\ into the Path field and click on Next.
* Specify the permission on the next page and you're done.

Solution 1: Summary

What we have accomplished here is we have separated your web site into multiple subdomains, while still keeping only one copy of the shared files across them.

Solution 2: Using isapi_rewrite

Whoa! That's a lot of steps to create all the subdomains I want. Is there an easier way? Well there is an alternative way. Let's get started first then we'll run the comparisons.

Setup DNS Server

Add the following entry into your DNS server and change the domain and IP address accordingly.

*.example.com IN A 1.2.3.4

Setup the Web Server

We are assuming that you already have a web site created for your main site: www.example.com. So let's just double check to make sure it will be able to accept all variations of the subdomains.

* Open IIS Management Console and select your web site.
* Right click on it and select Properties.
* Click on Web Site tab.
* Click on Advanced button.
* Make sure there is one entry under the Multiple identities for this Web Site with Host Header Name field blank. This entry will intercept all requests that comes to this IP address.
* Make sure the IP address is only used by this web site.

Setup httpd.ini for isapi_rewrite

Add the following code to your httpd.ini in the web root. Make sure they are in the right order.

# Convert http://example.com to http://www.example.com/
RewriteCond Host: ^example.com
RewriteRule (.*) http\://www\.example.com$1 [I,RP]

# Assuming we have limited number of shared folders.
# We will execute them accordingly regardless of the subdomain.
# Example: http://sub1.example.com/img/logo.jpg -> /img/logo.jpg
# Example: http://www.example.com/img/logo.jpg -> /img/logo.jpg
RewriteRule (/css/.*) $1 [I,O,L]
RewriteRule (/js/.*) $1 [I,O,L]
RewriteRule (/img/.*) $1 [I,O,L]

#Redirect all other subdirectories not matching
#to the list above as subdomains
#example: www.example.com\sub1 -> sub1.example.com
RewriteCond Host: www\.highspeed\.com
RewriteRule /(\w*)/(.*) http\://$1\.example\.com$2 [I,RP]

# If the web site starts with www then point the file to the root folder
# If you specifically created a folder /www/ then you can comment out this section.
RewriteCond Host: (?:www\.)example.com
RewriteRule (.*) $1 [I,O,L]

# Any web site starts other than www will be re-mapped to //
# Example: http://sub1.example.com/default.asp -> /sub1/default.asp
# Note: if the folder does not exists, then the user will get a 404 error automatically.
RewriteCond Host: (.*)\.example.com
RewriteRule (.*) /$1$2 [I,O,L]

#Fix missing slash char on folders
#This has to be at the end because if invalid dir exists,
#we should show 404 first
RewriteCond Host: (.*)
RewriteRule ([^.?]+[^.?/]) http\://$1$2/ [I,RP]

Test the Subdomains

Assuming we have the company website and two subdomains created: sub1, sub2.

URI ｦ Location on Server

http://www.example.com ｦ /
http://sub1.example.com/img/logo.jpg ｦ /img/logo.jpg
http://sub2.example.com ｦ /sub2/
http://abc.example.com ｦ /abc/ -> 404 Not Found

Solution 2: Summary

The second solution is easier to implement and only requires one instance of the website, the user has to be careful about creating the folders. For example, the user can not create a folder d:\inetpub\wwwroot\example.com\sub1\img\ because it would conflict with the isapi_rewrite Rule of (/img/.*). Therefore the files in that folder will not be accessible.

Comparisons

Multiple IIS Webs - Pros

* No conflicts to worry about between folders.
* Separate log files to track them individually.
* Can be setup for server farms and load balancing easily.

Multiple IIS Webs - Cons

* Need to create new site per subdomain.
* Requires access to IIS server.

isapi_rewrite - Pros

* Easy to setup.
* One server instance and log file.
* To add a subdomain, just add a new folder.

isapi_rewrite - Cons

* Need to keep track of directories to avoid conflicts.
* Need dedicated IP address.
* Additional resource for processing each file.
* Need to find server that supports isapi_rewrite.

Conclusion

While isapi_rewrite solution is much easier to implement, it is recommended for smaller sites with one development team. This is because of added resource and exceptions that the team has to keep track of. For a larger site, even though the admin has to setup multiple instances of the servers, these only need to be done once. Plus, the subdomains are probably developed by different teams and are distinct enough to warrant their own web instance.

So which one should you choose? Give the isapi_rewrite a try first. When you think your sites are big enough you can always switch to the other method anytime.

Happy coding!

SpiderinNET

http://msdn.microsoft.com/msdnmag/issues/02/10/SpiderinNET/
微软网站上的一个Spider代码，用VB.NET编写的。有源代码和程序下载。

SUMMARY

Visual Basic .NET comes loaded with features not available in previous versions, including a new threading model, custom class creation, and data streaming. Learn how to take advantage of these features with an application that is designed to extract information from Web pages for indexing purposes. This article also discusses basic database access, file I/O, extending classes for objects, and the use of opacity and transparency in forms.

Conclusion

My company's clients currently use Spider to retrieve information from local, state, and national sites. With some tweaking, the spider can be used to get address listings from public Yellow Pages, or articles related to certain topics from all over the Web. It could even be used to retrieve newsgroup postings from a news server. Any Web page can be crawled (as long as you obtain permission for copyrighted material first). Information obtained can be placed in a database for later analysis.

Visual Basic .NET comes with many new and exciting features. With time and a little perseverance, you'll learn when to use each. Improved array and error handling, GUI tricks, and stream support are just some of the tools that you have at your disposal when programming in Visual Basic .NET. Go out and discover some more for yourself.

UNIX Job Control

今天在Emacs里面按了Control-Z,但是我忘了怎样把后台程序弄到前台。
上网查了一下，答案在下面的文章里找到了，原来Control-Z不仅仅对Emacs有效，而是Unix系统里面控制作业进程的通用命令，而将后台的程序调到前台，则需要用%emacs来实现，可以用 jobs 或者 ps查询正在后台执行的作业或进程。
http://www.bu.edu/cc/support/aboutunix/general/jobcontrol/

UNIX Job Control

Any command or any sequence of commands joined by semicolons or by a pipeline is known as a job. Jobs can be suspended and resumed later or they can run "in the background." Background jobs are programs which have been executed in such a way that they return the shell prompt to you while they continue to operate, independent of the shell where they were created. The C shell has a number of built-in functions which enable you to control multiple jobs interactively. Note: running jobs in the background can be useful but may put an excessive load on the system if overused. The 'jobs' command will give you a list of active jobs.

Background and foreground jobs
A program can be run in the background by executing its command line with '&' at the end. For example, you could compile a 'c' program in the background.

% cc other.c -o oter &

%


Then, while the compilation proceeds, you could do some other work, such as edit some files with Emacs.

Later, you might have a new idea and decide that you want to change the source program for your c program to include the new idea. If you don't need the c program to finish its compilation, you could suspend Emacs with ^Z and then stop the compiler by using the kill command.

^Z (Suspend emacs)

Stopped (shell acknowledges)

% jobs

[1] Running cc other.c -o oter (jobs responds)

% kill %1

[1] Killed cc other.c -o oter (kill responds)


While you are at the shell prompt, you could pause to look for mail before resuming emacs:

% mail

No mail for you (mail responds)

% jobs

[1] +Stopped emacs (jobs responds)

% %1 (resume emacs)


In other words, you can resume a job that is stopped by typing %n where 'n' is its job number (the number that the 'jobs' command prints between [ and ]), and you can kill a suspended or stopped job. In fact, if you find yourself caught in a program and don't know how to get out of it, you can suspend the job and then kill it when you get back to the shell prompt. The scope of the 'jobs' command is limited to the shell that it runs under. Job numbers are con- venient references to processes under the control of a single shell.

If you have a job running under another shell that you want to stop, such as at another terminal (for example, you left a job running in the background -- some jobs will keep running), you can use the 'ps' command to find its Process ID (PID, a unique number used by the operating system to identify each process). You can then use the PID to kill the job with the 'kill' command.

% ps

PID TT STAT TIME COMMAND

23444 h4 R 0:00 ps

7158 ic R N 12:33 lisp

%





% kill 7158 (kill a procees by its PID number)

% ps

PID TT STAT TIME COMMAND

23555 h4 R 0:00 ps

%


If you try this method and the job still isn't gone, more drastic methods are needed. Add the -KILL (0r '-9' on some systems) flag as in:

% kill -KILL 7158


No program under UNIX can trap the KILL signal. Just 'kill' sends a -TERM (terminate) signal. This usually works, but if not, -KILL is a sure hit.

Command summary

& run in the background

Z suspend the current job

C interrupt (usually kill) current job

(some programs, such as editors trap

this -- so that a typo won't abruptly

terminate your editing session, losing

your most recent, unsaved work.)



D signal end of input

(log off shell, if issued at top level)



jobs display jobs running from this shell

ps display jobs you are running

ps -g display all jobs and login shells also

kill %n kill a job by job number

kill PID kill a job by process id number

kill -KILL PID a sure kill

('kill -9 PID' on some UNIX versions)


Notes

1. You cannot kill processes you don't own, but you can log in from another terminal and kill a job that has "locked up" your current terminal.
2. Killing your login shell (try 'ps -g') will log you out (Remember, you could force yourself off from a different terminal. When you examine the output of ps, look for the '-csh' commands. If you had an edit session active, you might try 'kill -HUP ###' as that simulates hanging up the 'phone' and most editors will try to preserve interrupted work.)
