March 8th

Busy busy busy!
This week was the most busiest week !!
I had an 10 pages of essay for my Anthropology course which was worth 50% of the grade,
I also had a scientific article to read and to write an abstract which was another 10%,
I had 1 quiz and 2nd midterms , and it was my friends birthday so
I had to finish everything before wednesday !!

For CSC104, I really did not have much time preparing for the quiz but I figured that
we were being tested on the similar concept as last week quiz so I didn't worry too much
I just took 30 mins or so to revisit the concept and manipulate them into the rackets
without looking at the videos and I was someout successful..
But the problem was the Project!
Basically, due to the busy busy week! I only had Friday to start on my Project,,
I was really worried at beggining abut I didn't know how to start,, for example,, the bouncing ball,,
I took some time, looked at it for several minutes and I just started making check-expects by looking at the some check expects below,, and I was able to slowly work things out..

But with alot of help from Prof Heap, and good community built by piazza,
I was able to finish the project, altho my ecosystem wasn't fully funcitoning right,,,
I was happy that I finished it!

One of the question I was struggling with was,,, that
(+ (- MICE-START (eaten-mice nm nf)) (new-mice num))
(ecosystem-mice eco))
for the definition of update ecosystem, but this didnt work and I was able to figure this out
by repcling nm nf and num with actual number, and made it to work by
(check-expect (new-foxes 10 10) (round (* 100 FOX-MOUSE-EAT-BREED-RATE)))
(check-expect (new-foxes 20 20) (round (* 400 FOX-MOUSE-EAT-BREED-RATE)))
(define (new-foxes nm nf) (round (* nf FOX-MOUSE-EAT-BREED-RATE nm)))

March 1st, Wikipedia 2nd part due and tutorial Quiz!

So,,
March 1st, was a very busy busy day!
First of all, I had a quiz on this day about the aggregate videos that I reviewed during reading week!
During that time, I didn't really understand the image-color list esp bluer C example

Thus, I went back to the http://docs.racket-lang.org/htdp-langs/intermediate-lam.html and
just looked at some basic information about the color. In the example,
Prof used the swap-red-blue c to make the images to turn more bluish color,
I wanted to mimic this and try to switch different colors and I was able to do so,,
Now that I think about,,,I find these vidoes which Prof uploads, very very very helpful..
I do look back to the racket langauge intermediate site and go over things I don't understand
but most of the times, Prof Heap explains it well in his vidoes and just being able to
visualize and hearing what he is doing on the rackets saves times and allow better
understandings..

I want to to Thank prof, Heap for making these videos and making the notes and videos!

Lastly, when working with Wikipedia 2nd part, I took a careful look at the each articles..I also looked at the talk pages and saw what sort of new informations or changes were being discussed and saw the potentials for me to manipulate those changes in future.
For example, I found out that one of the discussion on the talk page for the High Park article was asking for Cherry Trees which were donated to the High Park and wanted someone to add this information. So I did some research and found some information which I will be updating it with in wikipedia part 3. I also was able to find out that most of the articles did not upate their [[as of Date]] into {{As of |date}}. So I will be doing these changes also!

Reading week! Feb 22nd

Yes!
I had a great reading week,
I was able to catch up most of my courses especially CSB432, and EEB386.
I was very very far behind that courses but since I caught up all my courses,
I can now take some time going back to csc and start playing with some of the codings
we learned for the previous week tutorial or the week before,
I still have some trouble understanding aggregation video, decompose and reconstruct image.
One part I did not get was the
(color-list->bitmap
   (image->color-list-pingu
   192 262)
and then when playing with sizes, when making the width smaller and length larger,
Im not sure why the images for pengu gets distorted..I was expecting it to be just shorter in width
and longer in length.. Also when I took some random photo and tried it, i get error sometimes,
but overall, I get distorted, so I think maybe if you shorten the width too much, image just overlaps perhaps,, and the image for bluer blinky was a challenge at first but since I have a
week to re-learn and ask question if I still don't get, So I won't worry too much at this point!
Anyways, today was very a good day for me, had a wonderful dinner, hanged out with my friends
and I was very glad to hear that one of my friend who changed from life sceince to CSC got into an interview for microsoft in missisauga and I hope all the best!
Till then!

My 5th Post, Feb 15

Hi
Today I wanted to talk about some things that I was not able to understand first but was able to figure out later!
When I first looked at boolean logic, I was not able to figure out the the T/F.
And especially, Cin and Cout was very confusing in arithmetic. However, I did googled some
and looked at some youtube videos about and and i was able to figure out.
https://www.youtube.com/watch?v=-1gffkPjwXg is one vidoe which I looked at.
After doing some examples online, and examples from the notes, I was able to get a feel of it
and started to understand more and then I took sometime to look at the notes on numbers
and finally able to master it!
Sometimes I believe that, if I don't get some materials or have questions, I wanted to ask
but I tend to not,, I think its just my personality,, not asking questions in class and many
people ask questions after class so I somtimes don't get chances to ask about something I didn't get
or something I want to clarify...
This can be a problem I think,,, because I know that,, this could be on the test and if I don't
get things clarified before the exam I feel like I am not ready at all,,
Thus, I will try to ask more questions and emails and ask friends to help from now on!
Also, I have been looking at stuffs from before because I want to slowly get prepare and just
not get too far behind or forget things,, because I believe that this course, is not about
memorization, its more about understanding and just conciously know about it!

My 4th Post , Preparing for the TEST 1!

Hello,
In this post, I will be taking about my preparation for the Test1.
Basically, I was going through all the lectures and notes,,
writing down important things that I should remember and
coming up with my own examples, making up some questions
that might be on the test,,, etc etc. But when I saw the midterm
from the previous years, it only had 1 question about the computer devices...
So,, I faced a dilemma, I wasn't sure if I should take alot of time
memorizing history backgrounds and lecture notes or try to focus on
examples which were on the previous past exam. And then,, luckily when I
checked my emails to see what people were discussing about the midterms,
our prof sent an emails to us saying that we were allowed a double sided cheat sheet!
Thankfully, I just briefly looked over the notes and etc and wrote made short
summaries of each devices and some important notes on my cheat sheet.
This saved alot of the actual studying and remembering some of the excercises using Dr.Racket.
Thus, I was able to go through all the vidoes and sections of picturing programs which
were discussed and was able to walk in the exam room with a confident
and ended up getting an satisfied mark!!!

My 3rd post

Hi
This post is regarding Feb 1st, tutorial handout practices and the Wiki 1 project.
First of all, I wasn't really aware of the historic background of how computer was first discovered and what kind of inventions led to the modern computers.
It was interesting how they first used this clay tablets in 4000-1200 BCE to record and slowly gain its popularity. But more improtantly, it was interesting to find out how fast the inventions took place from one to another. I actually googled all the inventions and some youtube vidoes and it helped me remember them better and hopefully do well in the 1st midterm.

This week, for the tutorial quiz, I was expected to know the event vidoes and the picturing programs section 6.1 and 6.2. After going through, I had some basic understaing of preliminaries and tick handlers, i made some several examples with pictures of various sizes and animation windows of various sizes to familiarize myself with delevoping a basic animation that displace unchaning elements. However when developing an animation that flips upside down every 1.5 second in the center of the window was a challenge. And after playing it in Dr.Racket, I was able to figure this out using
(big-bang (overlay pic:calendar (rectangle 100 100 "solid" "white"))
(on-tick flip-vertical 3/2)
(on-draw show-it))

Lastly, when I was preparing to do a Wiki project 1, I did not know what to do at first..
I took some time and saw many articles which were needed to be improved in the Wiki community but I wasn't able to find many good ones so I decided to find articles that I was familiar with,
Thus I have chosen the articles such as HighPark, Koreans in Singapore (since I am korean) and HIV (because I took a virus course!)

Anyways, overall I enjoyed the lectures and enjoyed learning the computer devices and etc!

My 2nd post, january 25th

Hi,
This is suppose to be my second post, and I did miss some slogs up until February 16th, and in this slog
I want to tell a story about my unfortunate and inevitable circumstances which undesirably led to inconsistent slog posting.

First of all, I am currently running a start-up company as a CEO and Co-founder of the mobile application called HelpMeApp.
I have started the start-up company back in 2012 June. However, I had many conflicts with my co-founders and many doubts which caused a lot of stress and pressure. The hardest task was to communicate with my members by maintaining the boundaries between being a "leader" and a "friend". However, with lack of faiths and irresponsibility, some of our members left the team. I received their resignation letters around 5am, Friday January 25th, which was the day of our second quiz.

I stayed up until 4am, trying to familiarize with myself regarding the quiz materials and trying out all the functions in the tutorial videos (definition videos). However, when I received this letter, I was not able to sleep and was under a big stress. I tried to stay awake until the quiz but unfortunately, I slept in and woke up at 10am. I was really depressed and disappointed because I studied for the quiz until the late night ..

Basically,, I was unmotivated due to my circumstances and missing the quiz and I was thinking drop this course because I wrote in the first slog that I was very motivated and wanted to learn more about it, however it seemed like I failed to do so and just was not motivated enough under the situation that I was going through...

Thus, starting from January 25th, I faced more obstacles and doubts which led to irregular slog posting and just not enough inspiration to keep up with this course.As well, I have been sleeping very irregularly, changed  my mood, and started seeing my doctors and taking some depression pills...

But now, things are getting better and in terms of my health condition, I am getting healthier and sleeping earlier. I want to make this slog a turning point where from now on, I will always keep up with my slog, and be motivated to finish this course with satisfying mark!
