我也来说说射手播放器

最近射手播放器被炒的很火呀，这是不可否认的事实。几乎网上到处是关于它的新闻.
先是什么“在官方博客发表声明谴责QQ player不尊重开源”,后又被细心网友举报自身不遵守开源协议.这次乌龙事件真的搞得射手很没有面子。自己刚刚在大家心目中树立起来的国内开源先行者的高大形象被瞬间击得粉碎.

这也引起了广大的网友的唇枪舌战，很是热闹。
本来我是不打算蹚这趟浑水的，不过心里有些话真的是不吐不快。本人虽说没有对开源事业做过太大贡献,不过也算是一名开源爱好者，对开源的热情也是很高的.

在我看来，这次事件射手的确是不太地道,在自己还没有做到尽善尽美的情况下，还去高调抨击别人。
这种做事手段真的是让明眼人看不过去.

毫无疑问，射手播放器是建立在FFmpeg基础上的,用FFmpeg issue 上某位网友的话来讲，离开了FFmpeg，射手播放器就是一个空壳.而FFmpeg源码本身是基于GPL 和 LGPL 发放的,它要求任何基于它的项目都得按照自身情况,以上述的两个LICENSE中的一个开放项目源码.

网友们发现，射手播放器是遵循前者的，也就是GPL.这点在射手项目的SVN上也是可以看到的。
http://trac.splayer.org/browser/svplayer/License.txt (为此，我还特地的去读了读，为的是看看射手到底是不是被冤枉，还是怎么的.
附 中文译本的地址: http://www.thebigfly.com/gnu/gpl/ )

并且同时发现射手在代码库里面没有提供全部的源码，在某些分支下只提供了编译好的类库.

这个显然是违背GPL协议的（详见第三点的a小点,以及关于源码的定义）,当然射手对此也有解释，一堆一堆。
不过纵然你射手有千万个理由，有什么苦衷，你也不能因此不彻底开放源代码。要么你就不要声称自己遵循GPL，你可以去选择更加宽松的LGPL呀，又没人逼你. 古来鱼和熊掌不可兼得. 我认为cnbeta某位仁兄比喻的很恰当，"既想当婊子，又要立牌坊".

为什么人人都能严格遵循(比如大名鼎鼎的Mplayer)，而你射手就要搞特殊呢？看到你在FFmpeg issue 上极力的为自己争辩，你要知道你代表是整个中国的开源脸面.我可不希望你也被钉在FFmpeg 的耻辱柱上面。

我认为，作为一个开源爱好者，必须要严格遵循开源协议。如果都像臭名昭著的暴风影音那样，那么开源也就没人再去热衷.

就拿java里面的Spring 框架来讲，如果它是基于GPL发放的话，那么世界上所有的用到它的J2EE项目，都得遵循它，开放所有代码,哪怕没钱赚了也必须得开放源码。
没有为什么，要么你就不要用该框架. 当然也有一些肆意践踏开源协议的，抱着一副死猪不怕开水烫的态度，“我就用了,怎么的吧”.对于这种未开化的野蛮人，我们还能说什么?

当然这只是一个假设，Spring 实际上是基于Apache License Version 2.0 发放的,见下图:

[caption id="" align="alignnone" width="578" caption="spring in frme"][/caption]

这个可比GPL宽松多咯. :)

最后，对射手播放器今后的方向进行观望,不可否认的是,我的情绪已经开始不太稳定了 囧rz

秀一下我的火狐的插件

我不得不说，火狐浏览器是我用过的最爽的浏览器。

而它最吸引人的也就在于她的数以千计插件和在它们背后无数的插件开发者.

今天就来秀一秀我的ff必备的插件，当然，可能还有很多我没用过、没听说过的优秀的插件.

看图(由于一屏截不下来，所以截了两次，后期用PS拼接了一下..破绽百出呀)：

[caption id="" align="alignnone" width="536" caption="firefox plugins"][/caption]

PS:随着win7 发布和 ubuntu 9.10 发布,我已经刻好盘打算安装了. 为了避免重装ff丢三落四的找插件，截图以记录.

在centos上用mod_jk桥接apache与tomcat

最近在搞Volit提供的免费VPS,感觉有了自己的一台24x7不关机的服务器就是不一样，心里很是开心，不过现在的虚拟主机、VPS基本上都是LAMP这样的一个状况，LAMP的这个P就是指php 或者Perl,Python.
php这门语言虽然我草草学过，有了那么一点Base,姑且算是一个php starter吧～～
不过我感觉还是java来的更好一点，不管在写法规范，还是程序思想上，还是java舒服点，于是我便萌发了把java环境搭建到远程的centos系统上。

安装Java并不是什么难事，一个命令 yum install java-VERSION-openjdk 即可，这样的好处是环境变量也会自动配置好的，呵呵
然后就是tomcat（当然java的web容器并不止这一个，不过我比较喜欢）,它的二进制程序文件包可以在apache官网下载到。

最后就是如何让apache和tomcat之间开始桥接了，我搜索了一下，用到了apache的一个模块,叫mod_jk.so
关于这个mod_jk，着实让我郁闷了一阵，原来它有两个版本，一个是mod_jk2,一个是mod_jk.
刚开始，从名字上看，我想当然的以为mod_jk2是较新版本。可是我怎么也搜索不到下载地址
后来在apache的Archive镜像里面找到了,一看“最后修改时间”，吓死我了，2004年!!

后来才知道mod_jk2已经停止开发，mod_jk是现行的版本.最新版本是jk-1.2.28。
下载地址：http://www.apache.org/dist/tomcat/tomcat-connectors/jk/binaries/linux/jk-1.2.28/i586/

当然你也可以下载源码进行编译安装,而且呆会用到的workers.properties配置文件的sample也包含在源码包里面。
http://www.apache.org/dist/tomcat/tomcat-connectors/jk/source/jk-1.2.28/tomcat-connectors-1.2.28-src.tar.gz

搞清楚这些事情，接下来就好办了，复制mod_jk.so 到 apache下的modules目录，在httpd.conf里面load一下.
然后复制源码包里面的workers.properties文件到apache下的conf目录，打开，依照里面的说明和注释大概也可以看懂mod_jk的工作原理.

先指定tomcat的路径
workers.tomcat_home=/usr/local/tomcat
再制定jdk的路径
workers.java_home=/usr
然后就是一个worker的列表
创建一个worker,也可以是多个
worker.list=worker1 (,worker2,worker3...)
指定此worker1的类型
worker.worker1.type=ajp13
指定worker1的端口号
worker.worker1.port=8007
worker.worker1.port=8009
指定worker1的服务器路径
worker.worker1.host=localhost

以及下面一系列属性，可以参照
http://tomcat.apache.org/connectors-doc-archive/jk2/jk/workershowto.html#A%20sample%20worker.properties
去配置

worker.worker1.lbfactor=50
worker.worker1.cachesize=10
worker.worker1.cache_timeout=600
worker.worker1.socket_keepalive=1
worker.worker1.socket_timeout=300

配置好后，在apache的配置文件里面通过
JkWorkersFile /etc/httpd/conf/workers.properties 指定其位置

日志路径
JkLogFile /var/log/httpd/mod_jk.log
日志等级
JkLogLevel info
日志时间格式
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
指定增加或去除哪些功能模块
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
记录请求的格式
JkRequestLogFormat "%w %V %T"
指定哪些目录下的文件要通过tomcat转义，编译并指定列表中的哪个worker
JkMount /examples/servlet/* worker1
JkMount /examples/*.jsp worker1

以上这些建议写在VirtualHost节点里面，如果apache下有多个站点的话。
至此，就算是都配置好了，很多配置节点参见：http://tomcat.apache.org/connectors-doc-archive/jk2/jk/aphowto.html
tomcat目录/ sh startup.sh 启动tomcat.
apache目录/ bin/apachectl start 启动apache.
输入 http://localhost/ 看看吧

SourceForge.net Update: 2009-04-30 Edition

Oh!  We also plan to kick off our2009 Community Choice Awardsprogram next
week.  In the meantime, start thinking about the projects you want to
nominate!

== March Project of the Month: dotProject ==

dotProject is a Project Management tool written in PHP that aims to be a
best-of-breed project management system. Rather than a generic container
approach like a CMS or groupware app, we decided that we would do a generic
project management tool. We are not industry (or use specific), it's not a
project planning tool - it is designed to serve as an information gathering
and progress reporting tool.
