思念

咫尺天涯, 是因為心不在一起, 天涯咫尺卻是因為思念.

不在思念的家裏, 就是在往思念的路上.
真正的思念是無法短時間內停止下來, 只能讓時間來慢慢沖淡,
但也只能淡化, 將此思念轉換成另一種感覺, 變成自己可以承受的型態,
它有時會藏在口袋裡, 有時會躲在你喜愛的食物裡, 有時會隱身在你的書裡,
偶爾會出來刺你一下, 但此時你將已習慣此柔軟的刺痛.

difference between men and women

I am into difficult situation regarding my job, 

there is  a problem that we need to solve as soon as possible, 

but until now, I cannot find the best way to solve it. 

This situation gave me too much anxiety, 

so I asked my boss but he told me that it's alright and that he will try to look for someone to solve it.
Usually men doesn't like to ask for help because that will mean they are weak or useless 

but you can't solve problem by yourself. 

I think this is the biggest difference between men and women. 

I read  a book  informing me about that but I am not sure if that is true, 

but base on my experience it is proven.

coffee

Although I like the taste of coffee, I usually drink coffee at least once a month. 
If I will  drink too much coffee, I usually experience palpitations. 
Often times  after drinking coffee I can't sleep well which makes me feel uncomfortable.
My wife doesn't feel these symptoms and she can even sleep early after drinking coffee.
In spite of she doesn't like to drink too much coffee because we need to control our food expenses.
In fact drinking too much coffee is unhealthy.
In Taiwan some people are thinking that drinking coffee is a fashion trend, 
because whenever they have  a cup of coffee in their hands,it's  a kind of noble moves. 
In my opinion that's not a bad habit, if they will feel happy and will not try to interfere to other people's lives. Why not?

一對夫妻在蜜月旅途中....車突然拋錨~
男下車修理~搞了老半天都弄不好~
女:天色漸晚了耶~前面有家汽車旅館~我們過去那裡休息~說不定跟上次 一樣~睡一覺後車子就會好了~
男:那次是結婚前好不好~這次是真的車子壞了!!!

廣東一夥劫匪在搶劫銀行時說了一句至理名言：“通通不許動，錢是國家的，命是自己的！”
大家一聲不吭躺倒。
劫匪望了一眼躺在桌上四肢朝天的出納小姐，說：“請你躺文明些！這是劫財，又不是劫色！”
劫匪回去後，其中一個新來的碩士劫匪說：“老大，我們趕快數一下搶了多少錢。”
那老劫匪（小學畢業）說：“你傻啊？這麼多，你要數到什麼時候啊？今天晚上看看新聞不就知道了嗎。”

——這就叫工作經驗，這年頭工作經驗比學歷更重要！！！

劫匪走後，行長說，趕緊報案！
主任剛要走，行長急忙說：“等等！把我們上次私自挪用的五千萬也加上去！”
主任會意，陰笑道：“要是劫匪每個月都來搶一回就好了。”
第二天，新聞聯播報導銀行被搶了七千萬。
劫匪數來數去只有兩千萬。
老大罵道：“媽的，老子拼了一條命才搶了兩千萬，銀行行長動動嘴皮就賺了五千萬，看來這年頭還是要讀書啊！

Flex3 Localization

http://www.herrodius.com/blog/123


1. create a folder in your project src to store your resource bundles (e.g. "locale")
2. create a subfolder for each locale you want to implement (e.g. "locale\en_US" and "locale\zh_TW")
3. in the locale subfolder, create a resources.properties file and save it as UTF-8
4. enter the resources in the form of "key=value", like Ant property files
example:

   # locale/en_US/resources.properties
   login_id=id
   password=password

5. update the compiler settings: -locale=en_US,zh_TW -source-path=locale/{locale}

  [ResourceBundle("resources")]



< mx:FormItem label="{resourceManager.getString('resources', 'login_id')}" ....

switch your locale at runtime by setting the localeChain property on the resourceManager:

resourceManager.localeChain = ["en_US"];
//resourceManager.localeChain = ["zh_TW"];

Set focus on textfield in Flex3

In Action Script:
login.setFocus();

In HTML:

< body onload="setFlexAppFocus();">

   

2. detect press Enter

   

   /**
   * Handle login when user press enter on password
   */
   private function enterListener(e:KeyboardEvent):void {
       if(e.keyCode == Keyboard.ENTER) {
           enter(); // check login function
       }
   }

Asterisk 整合 VoiceXML

VoiceGlue
http://www.voiceglue.org/

安裝說明
http://voiceglue.org/wiki/doku.php?id=voiceglue_0.9_installation_instructions

因為我是用Gentoo , 所以只好使用困難的安裝方法 :-)
經過一番努力安裝完成後，接著就看設定部分
http://voiceglue.org/wiki/doku.php?id=voiceglue_0.9_user_guide

測試的 Dialplan 為
exten => 6666,1,NoOp("++++ Test voiceglue +++")
exten => 6666,n,Answer
exten => 6666,n,AGI(agi://localhost/url=http%3A%2F%2Flocalhost%2Fvxml%2Fhello.vxml)
exten => 6666,n,Hangup


http://localhost/vxml/hello.vxml 內容為

(vxml version="2.0" xmlns="http://www.w3.org/2001/vxml")
(form)
(block)
(prompt)
Welcome
(/prompt)
(/block)
(/form)
(/vxml)


voiceglue 預設是使用 flite 做為 TTS，
我們可以將其改用 espeak ，使其支援中文，方法如下：
修改 voiceglue_tts_gen
將其內容改為
system ("espeak", "-s 120", "-v", "zh", "-w", $file, "\"".$ARGV[1]."\"");
system ("mv", $file, $file . ".16khz.wav");
system ("sox", $file . ".16khz.wav", "-r", "8000", $file);
system ("rm", "-f", $file . ".16khz.wav");

就是這麼簡單 :-)

試著將 http://localhost/vxml/hello.vxml
中的 Welcome 改成中文，就可以聽到中文的語音囉

PS: 網頁必須是 UTF8 格式

Asterisk & 中文 TTS

espeak
http://espeak.sourceforge.net/
有支援中文的 TTS

asterisk-espeak is a eSpeak text-to-speech module for the Asterisk open-source PBX
http://asterisk-espeak.sourceforge.net/

若是用 asterisk 1.6.x 的版本，可參考以下的說明 patch
http://www.mail-archive.com/openpkg-cvs@openpkg.org/msg21782.html


記得要在 espeak.conf 設定
voice=zh
如此才會正確的處理中文


正確 install 成功後，測試的 Dialplan 如下
exten => 900,1,NoOp("+++++ Test espeak ++++")
exten => 900,n,Answer
exten => 900,n,espeak(測試中，你好，歡迎使用 asterisk |any)
exten => 900,n,Hangup


PS: 中文必須使用 UTF8 格式

Asterisk extensions.conf (二)

extensions.conf

設計撥號規則 (二)
-----------------------------------------------------------------
通常我們會將 extensions.conf 切分成好幾個檔,
然後再 include 進來 , 這樣比較好做規劃

例如: 將從 FXO 進線的撥號規則存入 fxo_incoming.conf ,
從 SIP 進線的撥號規則存入 sip_incoming.conf

在 extensions.conf 中 , 就可以用
;;; For fxo incoming
#include fxo_incoming.conf
;;; For sip incoming
#include sip_incoming.conf
將其檔案 include 進來 , 另外要注意的是有另一種 include ,
是 include context , 而非 include 檔案

例如在 extensions.conf 中

[test_context]
exten => 1234,1,Answer
.....
.....
;;; include context : test2_context
include test2_context

[test2_context]
exten => 2345,1,Answer
....
....

即表示 context [test_context] , 包括 [tests_context] 這個 context 內容
亦即 context [test_context] 設定為
exten => 1234,1,Answer
.....
.....
exten => 2345,1,Answer
....
....

--------------------------------------------------------------------------------
Asterisk 使用以下特殊用途 extension 名稱:

* i : 使用者按下沒有定義的 extension 號碼
* s : Start extension in context
* h : Hangup extension
* t : Timeout extension
* T : AbsolutTimeout() extension
* o : Operator extension, used for operator exit by pressing zero in voicemail
--------------------------------------------------------------------------------

Using a macro to create extensions

PHONE1=Zap/1
PHONE2=SIP/6002

;;; ${ARG1} 就等於 ${PHONE1} , ${ARG2} 就等於 ${PHONE3} 依此類推 ...
