Comments on variables

Matlab displays comments of functions when you tend to use it. It would be good if it can show the comment of variables while holding mouse on top of variable name. This way can provide a tool to remember what each variable if for without using long descriptive variable names.

mouse and pencil

While being a student my life is accomodated with two items   mouse and pencil.So why we are not combining them . Put a wireless mouse pen to one side and put a pencil to other side. A gyro sensor can figure out if mouse is active.

Robot Dish Washer

It is difficult to create robot that cleans our arbitrary dirty dishes. However  , if we put some digital information on dishes (special designed for this machine) such as RFID , than robot can easily understand the shape , coordinates and features of the dish. In this way it will be easy to optimize the placement of the dishes based on current dirty dishes information.
I imagine we can create machine that has two part , first part is regular dish washer and second part is open area for dirty dishes and attached robot hands at top. It will increase the size of the machine , but it may worth , especially for big restaurants.
