Week 6 : Midterm and Binaries

I noticed that I've forgot to update the blog last week due to a midterm tests.

We were given an access to past test, and I was preparing myself for it on thursday.  I find this course very amusing and interesting, and that interest kept me up to date with the class and I was quite confident before the test.  My only worry was to mix up the names of the famous contributors of computer science.  On the other hand, I was most confident about questions with DrRacket program, simply because it was my best interest and tutorials quizzes until today are all full mark.
And the test turned out to be very similar to last year, which made me, and I hope many others as well, easier to deal with.  Except for the last question, which I was confused with what the question was asking.  That complication lead till a very last minute, and I was not able to dash my pen on the very last question of the last page.  Overall, I found to test fine.  I hope I did well.

As for this week, I learnt about the binaries and digital system.  I was familiar with the system but the lecture was a little bit confusing when it came to a part with bitwise operators.  It took me a while after the lecture to figure out, but now I feel a lot more better with it.  Tutorial was easy as well.  I found aggregates and use of definition codes with museum very interesting, and thought for a while about their implications.  Once the lists are made and able to be processed, I assume there are more things that it can develop to, such as making particular list of numbers associated with different values represented by binaries.  Its hard to put it in words in here, but I'm interested in further work next week.

Past weeks were busy but I found them very worthy.  Since the midterm is over, I feel less stress regarding the class.  Only worry is the mark.

Week 4: Big-bang and Wiki Project

Late update... I hope one day is still acceptable without penalty or such sort...

This week's material was regarding of wikipedia project, which is separated in three parts over our semester, and about animating images with DrRacket.

This week's part for wikipedia project was relatively easy considering was is ahead of us.  Registration and submitting the pages I may edit was the task, and it finished in no time.  I consider following two kinds of editing in general: placing an image, and clean up after the translation.  Image finding seemed easy; only need time to find (or make) an image for the page.  As for a translation clean-up, I thought I could use my Japanese and edit pages such as University of Tokyo.  I'm more interested in translation clean-up.

The lecture in class was focusing on how to use command big-bang, which animates the image that is applied into the function.  I learned its capability with how I'm able to edit the frequency of frames in the animation, and what kind of animation I'm able to make, such as rotating (like a clock work) and flipping images in whichever 2D dimension.  I found it fascinating and I'm looking forward for what else the function is capable of.

My worry at this moment is the coming term test on Thursday.  I'm sure that I'm up to date with the lecture and tutorials, but I guess it is natural to be anxious of my performance to prove my required knowledge.  I only have one other test on tuesday for sociology, and aside from that I should be able to find enough time to go through the lecture slides to prepare myself.
