所以架了一台Jenkins，然後將之前寫過的sikuli 來測試一下
發現了一些錯誤，由於是透過Jenkin 去呼叫sikuli
導致sikuli在執行時的初始化畫面邊界大小錯誤
如下所示
[error] Location: outside any screen (23707968, 23707968) - subsequent actions might not work as expected
[error] Location: outside any screen (23707968, 23707968) - subsequent actions might not work as expected
後來上網查詢一下，也是有人使用類似的搭配，但是似乎只能在Jenkin slave 下執行sikuli

int playerA;int playerB;
if (playerA >playerB) {highscore =playerA;}else {highscore=playerB;}
這是個任何程式語言都常會看到跟使用的方法
但是在 Objective C 裡面可以寫成int highscore = (playerA>playerB)? playerA:playerB ;
短短的一行 就解決了上面數行這邊寫的很有意思 其結構就如同 condition? true:false
假設 (playerA>playerB) 這個condition 結果為true則 highscore＝playerA 反之如果為false , Scott Chenhttp://www.blogger.com/profile/06519303959981297310noreply@blogger.com0tag:blogger.com,1999:blog-13375716.post-8097518150615757032011-10-02T17:55:00.000+08:002011-10-02T17:55:33.049+08:00Apple app 另一個學習選擇～Lynda.com - Objective-C Essential TrainingLynda.com - Objective-C Essential Training
(這是一個朋友介紹給我學習的好影音教學阿）
優點有 分段介紹每個主題的課程比較短 容易迅速吸收
相較於stanford的影片動輒超過一個小時以上
學習起來比較容易累且這一個小時可能會被其他事情影響
（朋友同事call 你玩LOL、或者喜愛看得節目半小時後就要開演之類、or看大概半小時就想睡覺了之類的事情影響
另一個特色是他的教學內容是以Xcode4為教學內容
從基礎教起，非常適合新手跟入門的人來看
Lynda.com 是國外的教學網站
裡面的線上學習影片非常多元
除了Objective-C外，當然也包括了Android app 教學
如 Lynda.com - Android App Development with Java Essential Training
大家有興趣可以去該網站瞭解一下囉

因此最近開始研究
安裝多重OS 在同一顆硬碟上
首先測試的組合為
Rhel4 + Rhel5 x86 + Rhel5 x64 +Sles 10 x64
再加上其kernel & Xen 的模式
所以GRUB的開機選單為9個
1.先規劃好硬碟切割的空間
SWAP 一個讓每個OS 共用即可
/ 每個OS 擁有自己的根目錄
/boot 這個是最重要的地方! 每個OS 都必須要擁有自己獨立的boot folder
2.我安裝的順序分別為 Rhel5 > Rhel4 >Sles10
3.再來就是到預設的boot folder 底下去編輯
grub.conf 這個檔案
將其他的OS 的grub.conf 參數加入即可

Reference Counting
• Every object has a retain count
這邊提到 每個object 都有一個 retain 值
初始值為0
■ Defined on NSObject
■ As long as retain count is > 0, object is alive and valid
• alloc and copy create objects with retain count == 1

從 http://developer.apple.com/membercenter/index.action
登入apple ID 後
填寫 所有的相關資料
這裡要再老生常談的提醒大家
1. 請確定 apple ID 的帳號 與信用卡 中英文名要相同
2. 請確定 地址也是要相同
3. 電話都要一樣
最後他會轉到 apple online store 讓你再次確認購買人跟收件人的地址 還有信用卡資訊等
再來就是等待 Apple Developer Program Activation Code 的email 通知
依照這兩次的經驗 我大概都是下午訂購
隔天的下午 才會收到這封信
請耐心等候!

等等需要用到
最後確定目前 vSwitch 的狀態
#esxcfg-vswitch -l
(假設之前有設定不能用的話 需要手動刪除 再重新設定)
Step1.
Add vSwitch
esxcfg-vswitch -a "vSwitch Name"
#esxcfg-vswitch -a vSwitch0
Step2.
Add Port Group to vSwitch
esxcfg-vswitch -A "vSwitch Port Group Name" "vSwitch Name"
