CSE 91 Assignment 7

Part I:

Topic 2:  I do find it is hard sometimes to manage my time; I always have a lot of work to do that I don’t really want to do as well as well as a lot of fun things to do that I want to do but don’t necessarily have the time for.  However I find that I generally save enough time during the day to get done what I need to and I don’t have any huge problems.  If there were one thing I could change though it would be to start things like papers earlier so they will be better quality.

Topic 3:  I am not entirely sure what I would like to do after graduation.  I would like to start my own company and have several ideas for that, pretty much because I would be able to do whatever I felt like and not take orders from anybody.  I don’t really feel like I would want to go to grad school just because I don’t want to spend an insane amount of time going to school when I can be out living my life.

Part II:

The techniques I chose from that assignment so long ago were to stop using the computer for a time before I felt like sleeping and to ask my professors questions.  The first technique I found helpful; the second one not so much.  The one I liked was god because it really did help me get to sleep earlier so I wasn’t sleeping all day when I should have been going to class.  But I did not find asking questions of my professors to be very helpful because I felt that I acquired the right amount of knowledge and that questions wouldn’t be helpful to me.


CSE 91 Week 7 Assignment # 6

Part I:  This Voting system would print a list of whoever voted for who on a county website.  A system like this would have both pros and cons.  On the good hand, assuming whoever put the lists online were accurate and truthful and trustworthy, the results of the election would not really be in dispute.  We would all know the correct results of the election and be able to research for some types of voter fraud.

On the other hand this would undermine the whole point of secret ballots.  The secret ballot system was set up so that people could vote for whoever they want without fear or pressure from employers, family members, or politicians.  People voting for certain controversial candidates could be targeted and scared out of voting for them.

Part II:  I know a lot about the commerce that goes on with private data.  Just recently, Twitter sold a billion tweets to advertisers.  Facebook routinely sells all of its users private data to advertisers as well.  In fact, even your Google search results are different based on your web history.  A big concern besides from the fact that hundreds of companies knowing more of my personal information than banks do is security.  It may be tough to hack into Facebook’s servers, but once your information goes to 100 places, there are 100 times more sites that can be hacked to get your information.  And perhaps these sites’ security are not as good as Facebook’s security.

Pandora Radio uses a recommender system. It is used in its music recommendation for its end users.  


I generally like this system; it recomends good music most of the time.  It also lets you choose which bands you don’t like so they will stop playing it. However I would like if I could tell all the bands I like so itcould make an evrn better playlist for me.

CSE 91 Post 2

I am choosing the first two bullets, rest your brain and communicate with your instructors.

For the first one, I have always had trouble falling asleep, and it is especially bad now that I go to college and must wake up on my own for a 9:00 class.  A sort of sleep doctor said that it is bad to use the computer late at night if you want to sleep, and should cool down with reading a book or something.  So I will probably stop using the computer and read a book for 30 minutes or an hour so I can try to sleep at about midnight and get enough sleep for the night.

For the second one, it is always good to talk to your lecturers and ask questions.  You might learn some new things that you are having trouble understanding and they will probably appreciate you coming into their office hours and asking about something, because that is what they are there for, to help you learn.

CSE 91 Week 1

Hello CSE 91!  This is my week 1 post.

School at UCSD has been great so far.  I like my professors and this is really a beautiful place to live.  I learned some pretty cool things in my classes last quarter and look forward to learning more things in the future.

Actually the questions that Professor Baden posed in Monday’s lecture intrigued me–the ones about what technology we could have in the future.  I don’t think people 30 years ago could have envisioned the cool tech gadgets we have today, like 3D TVs and phones with quad-core processors, so I think it is really hard to envision what we could do in the future. However, I do have one product I’m thinking about.  I have read articles about trying to make silicon computer chips more flexible and I wonder if one could apply that to something like an iPad, so you could have a digital tablet that is just like a piece of paper, and that you can write on with a stylus.  It would be great for the environment (no more paper for anything) and would just be insanely cool.  Another thing I am thinking about is NFC communications, where instead of people having to send a link or a file over a current medium like e-mail or Facebook they could just pop it up on their phone and send it instantly to a friend or stranger around them or maybe even around the world.  It could be great for a variety of applications, including education.  However I see that devices are already coming out with NFC so this technology could be mastered in just 5 or 10 years.

I am not too worried about my exams so far, but about studying; I think it is important to just review the material you have learned over the course.  Last quarter I was doing quite badly in a math class because I hadn’t really been studying for the midterms; however near the end of the course I really studied very hard for the final and did well enough on it that I did alright in the class.
