20121228 貓空 煎茶院
久聞貓空大名，
還沒機會上去。

這次剛好跟上團，
不過，現在年輕人不喝茶嗎？

同行有念政大的，
都大說，怎麼會沒有人呢？

哈哈哈哈

唉～果然是懷念起，在東海時，
煮茶論劍的時代了。
暢聊一夜未眠，人生一大樂事。

20121221 世界末日

馬雅曆的新紀元開始了

2012年預言或2012年現象（2012 phenomenon）是一個關於末世論的預言、信仰或傳說、謠言，宣稱美洲的瑪雅文明中的瑪雅曆長達5,126年週期的結束，預言了地球、世界和人類社會在2012年12月21日之時前後數天之內將會發生全球性的災難性變化。此說法與太陽風暴、尼比魯碰撞、地球磁極反轉、網路機器人工程的預言等謠言結合，而成為2012年「世界末日說／人類滅亡說/人類重生說」，但至今目前為止，此說為社會各界認定是為一門偽科學，也是民間科學愛好者的次文化之一。[1]

Puppet class inheritance confusion - Server Fault
http://serverfault.com/questions/197909/puppet-class-inheritance-confusion


The difference between import and include statemens is:

import works with files, and does not execute classes
include executes classes
files must be imported before the classes can be included
Note: there is a very strong exception to the last rule: Puppet module lookup. include statement does automatic imports in many situations. Here are some of them:

include foo tries to import the file module_dir/foo/manifests/init.pp
include foo::bar imports module_dir/foo/manifests/bar.pp

[puppet]puppet plusignment "+>"

There are other ways to use inheritance. In Puppet 0.23.1 and higher, it’s possible to add values to resource parameters using the ‘+>’ (‘plusignment’) operator:


class apache {
service { 'apache': require => Package['httpd'] }
}

class apache-ssl inherits apache {
# host certificate is required for SSL to function
Service['apache'] { require +> File['apache.pem'] }
}

[puppet]puppet Serving Module Files

That is to say, if a module named test_module is installed in the central server’s /etc/puppet/modules directory,

the following puppet: URI…

puppet:///modules/test_module/testfile.txt

All puppet file server URIs are structured as follows:

puppet://{server hostname (optional)}/{mount point}/{remainder of path}

有時候想要看現在的 records 筆數與index size除了進去系統看實體index size外，
可直接使用 elastic search api。

[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
