Notes: SSD edition

Some notes from the past week:

  1. It is incredibly easy to be an impostor in a more academic party. First of all, most of the people will be already intoxicated to the point where bullshit science can’t be discerned from actual science. This is good as I can just say random facts I remember from Popular Science.Another acceptable thing to do is to just ask questions upon questions. “What’s your research? … Oh that’s so cool! Tell me more about it! … So does this connect to insert scientific news here? Wow.” That’ll burn around 5 minutes minimum.The main problem comes when you run out of questions in the initial barrage. It also fails when the person is laconic or can’t speak English.

  2. Installing a SSD is extremely easy, but installing operating systems are hard. Right now, I have around 8 entries on my GRUB menu before I migrate everything over to my new distro.I followed the mount guide provided here, which seems intuitive enough on where to put mount points. I’ve also learned that 
    mount

    and

    df -h

    are my friends. There’s also that good GParted software.

  3. The Lloyd Trefethren numerical linear algebra book is quite good for a quick overview of the subject. It doesn’t get bogged down with the analysis, and generally refers to other books (mainly the Van Loan) throughout.
  4. Holy shit URF mode.
  5. I need to be more brave in a certain subject….

Perfect Synergy

The past summer, I was at the REU in UMBC. The head of the math department guy preached about the future of mathematics is the intersection of mathematics, statistics and computing; I agree to a large extent. 

What I ended up working on seemed to be computing, with more computing, with very little mathematical analysis. The system of differential equations that described pancreatic cells was far too advanced for me to do some significant analysis. Heck, that’s how I feel about most of pure mathematics: the interesting problems are always out of reach from what I know.

Before this past winter break, I found a cool book called “Risk and Reward” in the math library. It’s all about the, surprisingly deep, game of casino blackjack, from the strategies to the mathematics behind the analysis. In the analysis portion of the book, 90

If I ever do become a professor of some sorts, I want to be able to teach a class based on games like blackjack and poker. For projects of sorts, the task will be to calculate the probability of various conditions and to figure out the strategies from the math I provide in class. Maybe for a (optional) final, it’s to actually play the games that we studied in class…

As an exercise over the break, I took an existing program and added the functionality to “practice” the card counting went over the book. It’s based on this project which I butchered (honestly, I spent 2 days doing this… trying to understand someone else’s code is tough). To run the program, make sure Python is installed, and run Blackjack.py. Download

Her and Bioshock

After watching the movie “Her“, I can’t help but think what the implications are for technology and human interaction in the future. What happens when artificial intelligence, on the scale of Samantha, is created? Will we as a being really turn towards that “perfect” relationship with a computer instead of nurturing (and suffering through) one with another human?

Those serious and interesting questions aside, I had no idea the voice of Samantha was of  the beautiful Scarlett Johansson. In my mind, I pictured someone who was quite beautiful just from the voice alone.

Same thing happened in Bioshock Infinite: the voice of Elizabeth seemed to be from a pretty attractive women (of course, the fact that the character itself was meticulously crafted to be pretty helped).

Turns out this isn’t a coincidence that a more pleasant voice goes along with a more attractive face. From paper:

Men were in strong agreement on which was an attractive voice and face; and women with attractive faces had attractive voices.

Whelp, I guess I’ll never voice a video game character.
