Amazing楼主是flybot的人吗? 本月21号有个聚会吧?
以前使用lisp做AI, 慕名clojure很久了。楼主常来分享一下吧。敢问目前技术用在本地何处呐? Walmat还是其他领域?
有没有比较过dotlisp与clojure的pro and con?
用在JVM上效率如何? 有没有memory leakage的情况?
So glad to see someone using lisp family tools. -

JVM men leakClojure用到很多jni吗？还leak?
研究Functional programming的是不大见待oop的。现在有人用pure oop的语言实现了functional programming 的解释器，有够讽刺的。 -

层主用过clojure?多多分享一下。
有啥商业好处和弊端的?

层主。你看看这一段, is it mem leak in clojure or not? I am not surewhen using httpkit to communicate to clients via websockets, the memory footprint grows apparently without bounds - depending on the system the process is then killed by the OS.
I looked at the memory usage in jconsole, and it's apparently the (new) metaspace that keeps growing. I managed to suppress the problem by passing -XX:MaxMetaspaceSize=128m to jar: In this case, the metaspace memory graph takes a dip whenever it exceeds the 128m, and the program doesn't end up eating all the memory. But it's a workaround - I'd like to understand why this growth is happening, but I'm not sure how to proceed. In C++, I'd track down leaks with valgrind, but since Java/Clojure is garbage-collected, I'm not sure what to look for.
I'm not 100% sure that it's only the httpkit code portion, but from my tests it seems like it - here's a code excerpt, where I'm listening for messages and depending on the message I send back a json object containing some data; coreparams-atom can be expected to have around 10 float entries at any time.
(httpkit/on-receive channel (fn [data]
(let [data-map (json/read-str data)
param (first (get data-map "data"))
value (second (get data-map "data"))]
(case (get data-map "type")
; ...
"curparams" (let [tosend (json/write-str
{:type "curparams"
:data (-> @state/coreparams-atom
(assoc :timestamp (db/timestamp))
(util/keyword-replace-char ":" "_"))})]
(httpkit/send! channel tosend))
; ...
))))
System:
Ubuntu 14.04
OpenJDK Runtime Environment (build 1.8.0_40-internal-b27)
6GB RAM
Clojure 1.6.0
http-kit 2.1.6
Similar behaviour on the same JVM on a CentOS to which I currently don't have access, so can't give detailed specs. -

是的，这个月21号有开课新加坡Clojure这方面的人才太少了。我们接手组织者一年多，才慢慢有点进展，但老板还是觉得进度太慢。
明人不说暗话，我们主要目的是招人。
文凭，年龄，性别不限，只看实力。
待遇可谈，薪资不封顶。
一面过后会出题测试，通过测试就可入职，没有太多套路。
如果有合适人选，可以帮忙推荐，不胜感激。 -

技术层面，不方便透露太多只能说大老板是技术出身，完美主义者，有严重的代码洁癖。
