Busy with final projects, and watching Pokemon.

Jesse: why did we do that?

May It Never Come
One began to hear it said that World War I was the chemists’ war,
World War II was the physicists’ war,
World War III (may it never come) will be the mathematicians’ war.
Monies
After 11 years of playing the clarinet, I have finally made some money from playing it. This past Sunday, I played in a gig for some Ithaca music group as a cuckoo in Saint-Saëns’ carnival.
Grant total profits? Fifteen dollars.
Made quite a dent in my two thousand dollar clarinet, and upwards of five thousand dollars worth of lessons.
Notes: SSD edition
Some notes from the past week:
- 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.
- 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.
- 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.
- Holy shit URF mode.
- I need to be more brave in a certain subject….
Damn
Didn’t even make top 500 for Putnam this past year. What a disappointment for me…
Ray Casting with JOGL
I won’t post the entire code here, because it’s pretty damn ugly. But here’s what I ended up doing:
- I used the
gluunproject
statement to find the beginning and end points to extrapolate a line from.
- Now that I have a line, I use the formula provided by Wikipedia using the vector formulation of the line.
- Simply do a loop over the vertices and find the minimum.
Sorry for note posting recently… I got caught up in things… 🙁
Position-based Dynamics: Start
Got collisions to work!
Hash
Doing another SPH implementation for parallel computing. It’s amazing how fast adding a hash table, instead of looking at all particles does for one’s speed. 1429.22 seconds to only 327 seconds. That’s 5 times as fast!
Meh
