    Goodbye, CS 130 

    Transcript of my Final Interview for CS 130

    Interviewer: Please reintroduce yourself to the audience.
    Me: *faces audience* Hi. I’m [NAME REDACTED]. I’m a Computer Science student.

    Interviewer: What were your thoughts when you enrolled in this course?
    Me: Totoo naman yung sinabi ko before na natuwa ako na si Sir Paul prof, marami kasi ako naririnig na nag-enjoy yung friends ko sa classes niya. Yung tipong nag-enjoy sila sa classes na hindi ko naman na-enjoy. Kaya ayun, nag-expect talaga ako na maging enjoyable yung CS 130. Tapos ayun. Masaya nga! 🙂

    Interviewer: How comfortable are you with math?
    Me: Hindi ako comfortable talaga sa math, or siguro tamad lang talaga ako as a person. Pero ngayon looking back sa sem na ‘to, medyo naging comfortable din ako nang onti sa CS 130. 🙂

    Interviewer: What’s your dominant feeling right now?
    Me: Wala, eto bida bida nag-susulat ng mahabang journal entry. Jk. I don’t feel any pressure right now – tapos na rin kasi yung sem kaya medyo chill na. Kaya sinusulit ko na rin yung journal entry kasi baka di na ako magsulat ulit ng ganito haha.

    Interviewer: Which topic/s in class made an impact to you? Why?
    Me: Hindi ko na talaga maalala yung titles ng topics, sorry. Pero siguro nagkaroon ng impact sa akin yung isang day na may pinarinig si Sir sa amin na audio file na nagloloop forever *ata*. Yung maraming sound waves na iba’t ibang kulay tas nagooverlap yung tunog nila. Siguro kasi parang sabi nila lagi di ba “bakit ako nag-aaral nito hindi naman ‘to magagamit”, eh mahilig ako sa music. So parang naisip ko, may gamit din pala ‘to sa something that I like or something that I experience everyday. 😮

    Interviewer: If you can summarize this course in one word or sentence, what would it be?
    Me: Aircon! Malamig kasi sa room. Sobra. Tapos sa lahat ng math related course na naexperience ko sa UP siguro ito yung pinaka-chill. Tapos cool pa yung prof! Oh, di ba? Wittyyyy.

    Interviewer: What would be your parting message to the class?
    Me: *takes a moment to wipe tears and asks for a bottle of water* Ayun, sana nag-enjoy din kayo as much as nag-enjoy ako sa CS 130. *drinks tubig* Salamat pala sa libreng tubig.

    Anyway, thank you classmates kasi ang fun niyo kasama tas ang funny ng mga ganap sa games lagi. Masaya dahil may games (Thanks sir!), pero kung wala namang g na players na willing mag-enjoy, sayang lang di baaa. Kaya thank you!

    Thanks din pala sa groupmates ko, ang dami ko rin natutunan sa inyo and sana may natutunan kayo sa akin. Sorry if sabaw ako minsan. 🙂 And salamat din sa mga namigay ng food sa akin na mga nakatabi ko kilala niyo na kung sino kayo! 🙂

    Thank you rin kay Sir Paul! Sorry pala nag-cut ako nung isang beses huhu pinagsisisihan ko talaga yun. Anyway, sana na-capture nitong interview yung pasasalamat at pag-enjoy ko sa class niyo sir! 😀

    Kitakits na lang klasmeyts, and congrats sa ating lahat! ❤

    Topic Four (Yay!) 

    Fourier Transform in Communication Systems

    The Fourier Transform is largely used in communications theory. It is essential to understanding how signals work through channels.

    Communication systems are “systems designed to transmit and receive information”. These information are transmitted using signals, and these signals are often viewed and analyzed in the frequency domain. Using the Fourier transform we can analyze these signals and the quality of these signals. We can also convert an analog system to a digital system using the the equations essential to the Fourier Transform.

    “Fourier Transform has greatly improved the way we are sending/collecting data.” For example, “when sound is recorded digitally the strength of the sound wave itself can be recorded (this is what a “.wav” file is), but more often these days the Fourier transform is recorded instead.” Later on, the Fourier transform signal is then “turned back into regular sound signal”.

    Fourier Transform is very helpful for images and sound files, like MP3s or JPEGs. It’s nice that we have these Transforms. I couldn’t imagine my phone without all my MP3 files!

    Wag mo akong ma-Terry Terry!!! 

    Symmetry in Social Interactions,
    sabi nga nila, wag mo gagawin sa iba yung ayaw mong gawin sayo

    Symmetry can be found in social interactions. An example of this would be the golden rule, “Do not do unto others what you do not want others to do unto you.” More philosophies involve symmetry – like karma. If you do something good/bad, something good/bad will be done to you.

    More examples of social interactions involving symmetry:

    • exchanging gifts and secret santas
    • reciprocated love/hate
    • favors
    • revenge “an eye for an eye”

    An example of revenge would be in the movie, Minsan Lang Kitang Iibigin (1994). No spoilers here! Melissa (Zsa Zsa Padilla) did something bad to Terry (Maricel Soriano) so Terry decided to do something bad to Melissa.

    and everyday life!

    Get’cha Head In The Game! 

    Vectors in Sports: Basketball

    Physics uses a lot of vectors. For example, you can use vectors to compute where a ball will go using velocity and acceleration vectors. Studying motion requires a knowledge of many vectors, like force, displacement, and torque.

    This picture illustrates Gabriella Montez and Taylor McKessie using vectors in high school to support their boyfriends in their upcoming basketball game:

    dear diary journal 

    Hi, my name is John Christian Sun. sun as in soon

    Nung nag-enroll ako sa CS 130 natuwa ako nung narinig ko si Sir Paul magiging prof kasi hindi ko pa siya nagiging prof before, and parang nagawa niya kasing enjoyable yung CS 30 nung iba kong friends. So naisip ko kahit ayoko ng math or science baka maging enjoyable naman yung CS 130. 😀 #pressure joke lang

    I’m not comfortable with math. Yung comfortable thoughts lang na naiisip ko about math is yung mga couches dun sa math lib. Pero di naman ako math hater. Pag may choice lang siguro, hindi math yung una kong pipiliin hehehe. Pero yeah!

    I’m feeling kinda sleepy pero dominant feeling ko ngayon is parang sabog. Di ko alam if yun yung proper term. Good morning!
