Ideas

1. YM, Pidgin,...
- When someone logs on to YM or Pidgin, our status will change to be visible for him/her.
2. Tool for supporting to write a kind of paper
For example, when writing a scientific paper, we usually base on some key questions. The format of paper is also a problem to a novice. We can develop a tool to support that information, and it reduces the time of writing papers. Sound good.
3. Virtual brain.
I'm thinking about this, because I don't want to remember too much, but I also don't want to miss any important events. So, a solution is using a service to remember them for us. Our brain will be free for creation. The question is where's our "virtual brain"? If these data is stored in one or several servers, what will we do if the connection to them is lost? What's about security?. The small devices like rings, glasses or electrical clocks seem to be suitable. In these devices, a software is embedded to support users. The wireless technology is applied here to make a connection to other digital devices, such as computers, mobiles,etc. With this device, we've just remembered a few actions: charging its power (feed it) and always bringing it beside us.
In the past, we use paper to save the important things. Now or in near future, we use electrical devices to do that, but with an extension of embedding actions associated with the saved data.

4. Multi-kernel operating systems for Multiprocessor machine

5. Multi-user on one computer (funny idea).
We have multi-processor system. We can plug some keyboards, mouse devices, screens, etc. to our computer. But only one user can use all of these devices at the same time. I'm thinking about Operating system that supports multi-user on this system. For example, at the present, only one window is activated. Why are two or more windows activated? If it happens, some users can use this system at the same time :D. Let's imagine some people sitting front of a computer, they are sharing screen, but working in different windows, textbox; they're typing at the same time, play the same game,... I think it's great and funny in some cases. Funny things sometimes are "stupid" things.

6. Tagging Filesystem.
Traditionally, we often organize and categorize files based on naming and locating them in directories. This is considered as one-tag Filesystem. Now, we extend to multi-tag Filesystem (or Tagging Filesystem) for easily searching, storing files in the system. By doing this, users have to remember tags (similar to remembering names of directories), but we can make connections or relationships among files in a particular topic.

7. Supporting phase-scheduling strategy to prioprity scheduler for parallel computing problem.

8. Building flexible control flow in OS (Linux as an example).

Idea on embedded OS

When I build Linux for embedded system, there are problems related to size of built-in kernel image. Linux image is often large. So, I think about idea of reducing the size of kernel dynamically at runtime depending on applications.

Planning our life: How softwares can do?

When working in the time-pressure enviroment, we often try to plan our works for a day, a week, a month, a year and may be for our life. Planning becomes a useful habit of active people in modern life, especially in the era of information technology.
How can IT support human? We can see that there are many softwares written for this purpose, but with me, they are not sufficient convenient for using in real world although they have many functions. We can list here some famous softwares: planning tool of OpenOffice and Microsoft, Tomboy, FreeMind,... We can easily see that OpenOffice or Microsoft are used mostly in software projects while Tomboy just has a few functions. So, I want to propose a new planning tool for personal life. This software should have some basic functions:

• Support sketching our tasks in a day.
• Support preparing essential resources for each task.
• Support confirming what tasks are finished or done.
• Support reminding us some important events or tasks.
• Analyse our works to increase efficiency of planning tasks.
• We can see our plan wherever we are (networked data) with whatever tool we have (mobile, PC,...).
  
• ...

I have just listed here some functions. I'm going to implement this tool on Linux OS, something like GDesklet. I also hope that someone will understand these suggestions and make one for us. It's very good :).
