推荐私人免费项目管理及SVN服务:unfuddle

David — Fri, 28 Nov 2008 03:40:03 +0000

站点主页:http://unfuddle.com/

如果你要写的是开源项目，那么你可以有很多的选择，而当你想写个非开源项目，只是需要一个项目管理和SVN服务时，选择就很小了。unfuddle提供的免费计划很适合这个需求。

200MB空间,一个项目,2人管理,3个记事本,Subversion 和 Git 支持;
提供内部消息、里程碑、Bug跟踪、RSS和iCal支持。

这是我最近在写一个私人项目时，根据我的需求找到的，个人非常满意。所以推荐给大家。

VMware 推出免费的ESXi虚拟化产品

David — Tue, 29 Jul 2008 06:12:33 +0000

虽然之前已经有免费版本的VMware Server之类的免费服务器虚拟化产品,但那都是基于现有操作系统之上的。而ESXi是VMware第一个类似ESX的免费服务器虚拟化产品(直接可以安装到裸机上),看来面对Windows 2008的Hyper-V,Citrix’s Xen等的压力,VMware还是有所反应的。

推荐免费邮件安全证书:Free Secure E-mail Certificates(2)

David — Sat, 03 May 2008 04:52:51 +0000

我们为什么需要邮件安全证书呢？由于目前的邮件协议是明文传输，所以，随时存在邮件被窃听和篡改的可能．邮件安全证书能实现如下功能:

加密重要邮件，并确保只有收件人才能阅读．
签名你的邮件，确保邮件来自你本人，并且没有被任何人修改．

接着上篇，继续介绍另一个免费邮件安全证书。

主页:http://www.comodo.com
Free Secure Email Certificates 是免费提供的，访问申请页面:http://www.comodo.com/products/certificate_services/email_certificate.html.如下图：

点击图中的”GET YOUR FREE EMAIL CERT NOW!”,将进入申请程序，显示如下：

如图中填入相关基本信息和取消该证书的密码,向下翻页，看到一个许可协议，点击“Agree & Continue”按钮。

ok,现在就可以去邮箱看是否有来自Comodo的邮件，邮件内容如下图:

点击邮件中的红色按钮，就会自动下载证书到浏览器中。最后，根据需要从浏览器导出证书，导入到相应的邮件系统中．然后我们就可以开始使用邮件安全证书的签名和加密功能了．
