Focus

  The main problem now is concentration. How to concentrate, especially when you don't know well about your missions.
  Context: when you first start-up your computer, you will check the internet connection, then surf the internet. There was an advise about this, you shouldn't write down the line such as surfing the internet on free time. It sounds you are as a playboy. After reading the news online, then you check for the applications for the new laptop. There are some problems occur during the registration or downloading, then you will fix, from one application to another, and then finding the serial, fix again and again. As a result, when you look at the time, you will see that you waste all day just for surfing the internet and download something which are not essential at that time.
  Solution: you have to write down the specific tasks that you have to do. And then you just step by step finishing them no matter what they are, what occur. It is proven that when you don't use the browser for reading news, you can save a lot of time for more useful tasks.
  Let's try now and keep the progress. Don't be lost, man!

Good news & Bad news

     Nowadays, every morning news in Viet Nam is just around the blackout and water cut. There are not any apologies from the directors of each departments. They just informed in the news, and the people will arrange themselves.

    

     The government launch a new campaign name "The year of the Youth". Ironically, the youth just can say nothing but obey the government rules. They just beg money for the youth whom they call the poor. I wonder what the youth will get from the campaign.

     The border of Viet Nam is narrow down little by little. The youth don't have any right to open their mouths. They want to protest, but the under cover men silently just arrest the youth protesters. What a sad thing!

Specifying the scope of the problem before solving

    On the very first week, the new idea about incremental view updating was accepted. However, after working with specific example that Prof. Kato gave, there were some troubles with tracking the information from the view back to the source of the forward transformation.

    One week later, Prof. Hu sent us a paper named "Origin tracking", and we should consider if we can apply the technique to solve our problem. Before the meeting today, the main problem is that how create rule from graph input so that we can trace. After the discussion and explanation from Profs. , there are 3 important things that I recognize:

    First, one is that creating rule from graph input isn't the main problem because in the Term Rewriting System, the comparison between notes can be animate at any points. Moreover, with the simple rule that I suggested in the slide, it is actually the rule as it is.

    Second, the previous example of Prof. Kato was so complicated (with the 'or' operator - apply for father|son and mother|daughter). So, I need to create a more simple one (just very simple).

    Third, the final things that is very important to me is that the scope of the problem. It's very large example so that I can't test my expressions (extend-where, delete-where and replace-where). As a result, I need to create a simple example so that I can test my expressions. After that, I can create more complex and complicated compositions.

    That's all I have to remember and keep in my mind (keep it as simple as possible to test, and then develop to complicated one)
