Allright, allright, I'll stop hoping for a comment and continue.

I said screw it, and got a membership to the gym and big bottle of creatine monohydrate. I'm gonna hit 190 one way or another. I'll be bloated with water, barely any abs, and the scale will teeter at 190, but I'll be there.

We are getting some interesting lectures from head managers from all aspects of the CGGVeritas business. We do a lot of stuff, even though it may all seem the same. Most of it has to do with the Gulf of Mexico and the challenges it presents. There are these giant pockets of salt everywhere, and it makes everyones job more difficult. One of the really interesting things they are doing now is adding Wide Azimuth Marine Surveys to the repetoire. To understand this, you have to understand how a traditional marine survey is shot. Basically a ship towing a bunch of streamers about 10k long with sensors all along. Right behind the ship is an array of pressurized air sources, that make big bubbles which make our seismic data. What wide azimuth does is add 2 more ships with these pressurized air sources on either side of the main ship with streamers, thus adding more angles of attack so to speak for the seismic sound waves. It costs many times more, there ends up being so much data we don't even know if we can process it, and it'll take about 3-4 times as long to do. But big oil cries for big money, and we all know, if you throw enough money at a problem, it'll go away.

I get to explain linear prediction in frequency-phase shift space as a means of anti-aliasing of seismic data in regards to spatial interpolation . What does this mean? Lots of Fourier, lots of matrices, and lots of complex analysis. Yeah...YEAH!!! No. Basically making fake traces (what a seismic sensor recieves from a shot) and predicting what wave it would recieve based on what the data around it looks like so that we can get rid of a nasty property of turning analogue waves into digital ones.

So I dunno what else right now. I had the terrible idea that perhaps my lower back was hurting because it was weak, so I should work it directly. I've been a useless bum who can't bend over all day. My moroccan roomate is driving me nuts, and everyone else for that matter. I realize, it don't matter how smart you are, it don't mean shit if no one wants to/can work with you. A bunch of pretty smart guys will always do better than one really smart guy.

Oh yeah, I saw the Nexen Long Lake project for you Nexicans. Wow, that looks like a big giant pain in the ass to do, even the seismic is a bitch to shoot. Depth analysis at 350ms with hard rock right underneath? Yeah, that's like shooting blindfolded.
