golang.org and Google is blocked in china by government, so, Google trends and golang.org traffic from China maybe miss leading.
Go is quite popular in china, the reasons can be:
1. A few companies is based on Golang, like qiniu.com.
2. More and more companies are adopting Golang, since it's very powerful for writing network servers. These companies are facing very fast traffic growth. Golang's efficiency and expressiveness are well known. It just fills the gap.
3. China has many software developers spread in a few cities(Beijing, Shanhai, Hangzhou, etc). News spread quite effective among them.
It monitors a directory for change (using notify facility provided by the OS), upon change, will execute a given command given by command line arg `-command`. If any browser connected, it will try to refresh the browser too.
IntelliJ is the best IDE out there. It might be pricy, but it will save you so much time in the long run. Since time is money, you will end up saving money too. :)
Clojure runs quite fast, in my experience. I have written an web app http://rssminer.net, in Clojure (and some Java). On a small VPS(512M RAM, 1 core CPU), It can handle about 300 request per second, On my desktop, about 2000 req/s. Which is not slow, at least.
The persistent data structures Clojure use is fast too. I did some test a long ago, It's roughly the same speed as Java collections.
Almost every app requests too many permissions. Almost every app starts a background process to receive notifications. which are very bad.
