delete in operation_item_controller.rb has problem, when updating items' ranks

model cannot use type as attribute name

Cannot use "type" as attributed name in model.

it will issue an error when you use find, e.g., Operation.find :all
>> Operation.find 1
SyntaxError: compile error
/home/tk/eclipse/flex/ihp-report/branches/march/IHP/vendor/rails/activerecord/lib/active_record/base.rb:1748: syntax error, unexpected tINTEGER
Object::0

shit

今天要做的事

一、看曉偉的東西，
二、experiment about that "does greedy algorithm produce optimal solutions for file transfer problem."
三、artit 的東西。
四、funwish 的東西。
五、multi-core meeting, tutorial
六、

2nd open 64 tutorial

where does mcf-seq-f and mcf-par-f come from? are they copied from the outputs of 1st tutorial ?

鏡子

鏡子，今天要去買鏡子。
昨天跟依親聊天時她的匿稱也是鏡子，剛看msn的列表時也有人是到鏡子。
這是什麼預兆呢？

xrandr

interesting stuff : xrandrx

xrandr --auto ( auto-detect newly add screen(VGA, another monitor, projctor, etc.))

xrandr --output VGA-0 --right-of LVDS ( create a big screen where VGA-0 is right of LVDS )

an optimal solution for edge-contention is an optimal solution for out-degree? or vice versa?

There is a simple question:

an optimal solution for out-degree-minimization is an optimal solution for edge contention?

If we say a solution is optimal for edge-contention, is it an optimal solution for out-degree-minimization?

要做的

寫程式測試 file transfer problem 的 greedy 的演算法是否有反例

試 open64
