The latest statistics from WeChat place its monthly active users (MAU) at 700million, with audiences visiting the application upwards of 30 times per day.
While follower numbers for most brands continue to grow, the honeymoon appears to be over. Signs are starting to emerge that follower growth rates for brand accounts are slowing.
At the same time, the government has started to apply pressure to regulate H5 apps built onto WeChat. And Tencent itself is applying greater control over brand activities.
Brands will have to employ more effective content strategies on WeChat moving forward. In this presentation we share our tips to help brands continue to grow by attracting/retaining audiences on WeChat.

Introduction to Basic Haskell Components (In Chinese)ChengHui Weng
In 2012, we had the first Chinese functional meetup about general functional programming techniques in Taipei. I gave this talk to introduce several classes in the famous Typeclassesopedia article.
标题:
Architecture and Practice for DAL (5) Data Sharding
Architecture and Practice for Data Access Layer (5) Data Sharding
联动优势数据访问层DAL架构和实践之五:分片数据分片
说明:
How to implement a dalet to access sharding databases.
和已有DAL软件(如许超前DAL手机之家、陈思儒Amoeba/贺贤懋Cobar等)不一样,在前端访问方式的选择上,抛弃JDBC方式,而是为同一个dalet数据服务,同时提供自定义TCP长连接和HTTP长连接两种接口。
因而通过抛弃JDBC可以获得多方面的好处——
1)可减少S端协议解析和查询分析的开销;
2)也简化C端编程。
3)后端存储就不再限于RDB了,而可以是任意NOSQL、文件、缓存、甚至是Tuxedo等在线服务。
4)可以实现无状态了,更容易横向扩展。
5)从接口上就可消除join等关键字的误用,避免引起服务端负担过重。
33. cout<<” A int :”<<a<<endl;
}
void display(char a);
{
cout<<” A char :”<<a<<endl;
}
程序运行结果:
A int:12
A double:12.5
A char: A
第一行的结果调用了 void display(int), 第二行输出和 void display(double) 匹配,第三行输出和
void display(char) 匹配。
