扩展Thymeleaf-1 为什么需要扩展Thymeleaf

gitbook [http://vincentmi.gitbooks.io/extendingthymeleaf/content/][http://vincentmi.gitbooks.io/extendingthymeleaf/content/]

Thymeleaf是一个很容易扩展的库。他的关键在于，大部分面向用户的功能不是直接构建在他的核心中，而是通过打包和组件化到一个称为Dialects(方言)的功能集合中。

dockerpool CA 证书错误

docker被墙后用，拉dockerpool的镜像会出现这个错误 > sudo docker pull dl.dockerpool.com:5000/centos:7 FATA[0000] Error response from daemon: v1 ping attempt failed with error: Get https://dl.dockerpool.com:5000/v1/_ping: tls: oversized record received with length 28012. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry dl.dockerpool.com:5000` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/dl.dockerpool.com:5000/ca.crt 解决方法，在/etc/sysconfig/docker添加 INSECURE_REGISTRY='--insecure-registry dl.dockerpool.com:5000' 版本如下

在CentOS下安装PPTP的VPN

http://www.black-xstar.com/blog/691.html 最近买了个基于xen的VPS玩玩，安装LAMP没啥意思。国内网络环境不好，干脆安装个VPN试试。对于Linux其实我什么都不会的，在google老师的帮助下，总算给我安装好了，记录下来以便查阅。 VPN常用有两种，一种是openvpn，另一种PPTP。前者开源跨平台功能强大，后者

CXF添加Header

CXF的header处理了半天。。。添加拦截器 public class HotelHeaderInterceptor extends AbstractSoapInterceptor { public void handleMessage(SoapMessage message) throws Fault { List<Header> headers = message.getHeaders(); AuthenticationHeader aheader = new AuthenticationHeader(); aheader.setCulture(com.tourico.schemas.webservices.authentication.Culture.EN_US); aheader.setLoginName(username); aheader.setPassword(password); aheader.setVersion(new JAXBElement<String>(new QName("", "version"), String.class, version)); JAXBElement<AuthenticationHeader> authHeaders = new ObjectFactory().createAuthenticationHeader(aheader); Header header; try { header = new Header(authHeaders.getName(), aheader,new JAXBDataBinding(AuthenticationHeader.class)); headers.add(header); message.put(Header.HEADER_LIST, headers); } catch (JAXBException e) { e.printStackTrace(); } } 调用服务之前处理 IDestinationContracts port = service.getIISDestinationHosting() ; Client cxfClient = ClientProxy.getClient(port); cxfClient.getOutInterceptors().add(new HeaderInterceptor(Phase.WRITE));

用RF24创建无线传感器网络

英文原版 https://maniacbug.wordpress.com/2012/03/30/rf24network/

翻译: Vincent Mi http://vnzmi.com/rf24network-for-wireless-sensor-networking.html

RF24Network网络是一个使用Nordic nRF24L01+ 无线，运行在Arduino兼容硬件的网络层。他的目标是成为Arduino单元通信的除Xbee外的另外一个选择。他提供一个主机地址空间和消息路由最高支持6000个节点，形成一个有能力和可扩展的无线传感器网络系统。同时让两个节点之间的通讯更加简单。
