Google App Engine开始支持java啦

这个崭新的LOGO漂亮吧，哈哈

自Python后，谷歌终于提供了对其他语言的支持,估计以后会越来越多。

让这个强大的功能可以被我们更好，更广泛的利用,不至于荒废了。话说 python没学过.

先申请开通了，稍后再写出攻略，呵呵

谷歌音乐上线啦

最近听说google 开通了在线音乐服务，但是不知道究竟是怎么个样子。最近看到国内各大新闻都在关注这件事情前几天在cnbeta 上看到说正式上线了，一直没用过。因为对于我这个只喜欢在本地硬盘上用播放器听歌的人来说，的确没什么诱惑力不过，在谷歌之前，在线音乐&下载貌似一直是百度的天下，这次不知道谷歌是不是要抢夺地盘啊，我本人也是百度mp3 的用户，也会经常搜索一些或下载音乐. 于是，今天特地去用了下谷歌的这个新产品. 打开谷歌首页，发现谷歌音乐已经成为谷歌首推的服务出现在了下方如图：

呵呵，看来谷歌对这个是抱有了很大信心呀点开之后，进入了谷歌音乐的页面，一个鲜明的logo 出现在上方，我们可以清楚的看到 "测试"的字样

如图：

一看之下，发现内容还挺丰富的，有排行榜之类的

我试着搜索了一位歌手的名字，系统自动罗列出了他自出道以来的所有发行的歌曲.

给人感觉很不错。随机点了一首歌曲

便跳出网页播放器了，不过，在播放之前，用户得先同意一个协议，才能继续

如图：

这个可能是涉及到版权问题，同意便是. 毕竟人家提供的是正版的音乐试听

播放速度貌似也不错，如果觉得歌曲不错，还可以下载到本地。

如图:

看看文件大小，果真是正版的音乐呀，和我们从CD里面提取出来的分毫不差

哈哈，以后再也不用花冤枉钱去买周董的专辑啦.

sf项目主页全攻略

很多在 Sourceforge.net 上做项目的朋友，大多会忽视的一个服务----就是SF免费提供的项目主页的功能。

其实，有一个类似于 xxx.sourcefoge.net 的主页，对自己项目的宣传也不是一件坏事呀，哈哈。而且SF提供的Virtual Host 功能非常优质，几乎支持所有语言，如 PHP (via mod_php), Perl, Python, Tcl, Ruby, and shell scripts.

不支持的很少,是
SSL (encryption)
SF.net User Authentication
JSP (programming language) support
Microsoft Front Page and Extensions
Dreamweaver Remote Admin support

并且还提供 mysql 数据库支持，还可以用自己的域名去访问，只需要做一下A ,Cname记录：

Using the tools provided by your DNS provider, configure the following:

yourdomain.com should be a IN A to 216.34.181.97.

www.yourdomain.com should be a CNAME to vhost.sourceforge.net.

cvs.yourdomain.com should be a CNAME to PROJECTNAME.cvs.sourceforge.net.

把自己在本地做好的网页文件上传到空间里面，有两种途径。

1.通过sftp----比较简易，功能较少

就拿putty 套件里面的PSFTP.EXE 来说，打开后，输入 "open 用户名,项目名@web.sourceforge.net" 回车。再输入密码就可以了

如图：

2.就是通过shell.sourceforge.net 访问.

Project shell server: shell.sourceforge.net
Project CVS server:
PROJECTNAME.cvs.sourceforge.net
Project Subversion server:
PROJECTNAME.svn.sourceforge.net

这个要用到SSH，首先得生成一个SSH Key ,我们可以用putty 套件里面的 PUTTYGEN.EXE, 运行后在parameter 里选择 "SSH2 DSA". 然后点击 "Generate" 按钮，你所要做的事是：把鼠标指针在上方空白处晃动，以便随机生成KEY，完了后在Key comment 处填上 "用户名@shell.sourceforge.net" ,最后点击 "Save private key" 保存为 *.ppk 文件.

注："Key passphrase " 和 "Confirm passphrase" 可以不填。

如图：

现在你要做的是：把上方 "Public key for pasting into OpenSSH authorized_keys2 file" 框里面的所有字符复制下来。

然后，登录你的sf帐号，切换到 "Account Options", 在 “Host Access Information ” 处点击 [Edit SSH Keys for Shell/CVS], 把复制的字符粘贴进去。点击 update 即可。

注：如果是两个KEY或者多个的话，要确保KEY与KEY之间有且只有一个回车,KEY中间不能有空格.

如图:

如果没有错误的话，应该会即时显示出 SSH key 的数量。如图

SSH KEY 生效大概只要几分钟就可以了，很快的

好了后就要去激活 SSH shell. 我们要用到PUTTY 套件里面的 PAGEANT.EXE 和 PUTTY.EXE.

首先，运行PAGEANT.EXE ，在任务栏找到它，双击，点击 "Add Key ",浏览到先前保存的 *.ppk ，确定即可。

如图:

然后，运行 putty.exe , 注意：在此后的操作都建立在 Key Agent 基础上，所以 PAGEANT.EXE 不能关闭.

设置putty，见下面的表格

Session	Host Name: "shell.sourceforge.net"
Session	Connection Type: "SSH"
Connection > SSH > TTY	uncheck "Don't allocate a pseudo-terminal"
Connection > SSH	Remote command: "create"
Connection > Data	Auto-login username: "用户名,项目名"
