MS SQL (GROUP BY)
Google 關鍵字: group by many columns -> group by multiple columns sql
"Group By X" means "put all those with the same value for X in the one group.
"Group By X, Y" means "put all those with the same values for both X and Y in the one group."
GROUP BY 多個欄位: 指定到的欄位都要有相同的值 才能將TABLE的ROW結合在一起

jquery .live()
js動態生成的dom元素得用live進行事件委託，如
$(".t").live("click",function(){
alert(this);
});
這樣樣式為t的元素就能觸發click事件，

No enclosing instance of type is accessible. Must qualify the allocation with an enclosing instance of type (e.g. x.new A() where x is an instance of )
You can get the error,if you try to instantiate an inner class without an instance of the outer class.

[java error] The type List is not generic; it cannot be parameterized with arguments
The type List is not generic; it cannot be parameterized with arguments
List 類型不是通用的；無法利用 <Map.Entry<String,Integer>> 引數來將它參數化
complier後出現這個錯誤，
結果 import java.awt.List; 這裡竟然用了awt的List
修改為 importjava.util.List;

解決weka heap size不夠問題
在weka的安裝目錄中找到
RunWEKA.ini這個檔案
把maxheap=512m改成maxheap=1g
按log那隻鳥(weka)右鍵 */*/maxsize 就變成1XXX,XXX,XXX byte了
然後再把檔案load進去 就成功了耶!!
