[rvm] install ruby rvm

#curl -L https://get.rvm.io | bash -s stable --ruby


Installation of RVM in /usr/local/rvm/ is almost complete:

* First you need to add all users that will be using rvm to 'rvm' group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
in all your open shell windows, in rare cases you need to reopen all shell windows.


#gpasswd -a root rvm

[movie] 愛 (電影)

愛 (電影) - 维基百科，自由的百科全书
http://zh.wikipedia.org/wiki/%E6%84%9B_(%E9%9B%BB%E5%BD%B1)


一直都有好評的戲，
但是我沒想到，對自己的衝擊很大。

很多時候，以為我們自己真的懂得愛了。
可是，我們卻要為了我們自以為的愛默哀。

愛 要是對了，就是那麼簡單自然的一件事情。

過了這村，就沒有這個店了。

你多久沒有思考 愛 了嗎

[travel]121110 富陽生態公園 維護 關閉

之前在找房子就有看到這附近不遠處有登山步道，
今天看起天氣很好。
所以想去晒晒太陽，帶著水跟水果就想往那邊出發。




哈，
非常不妙的。

富陽生態公園 在維護～～～～ 而且是整個關閉 oh no



前前後後也看了不少人是要過來走走的，
還有家長們帶著小孩子過來。




期待整修後的環境

今天早上看到一張辦公室的圖，
想起來現在位置其實滿棒的。



忙碌完畢後，我最喜歡對著外面發呆了。
