"Life is a storm, my young friend. You will bask in the sunlight one moment, be shattered on the rocks the next. What makes you a man is what you do when that storm comes. You must look into that storm and shout as you did in Rome. Do your worst, for I will do mine!"

A Great Quote
This is a great quote from the movie, "The Count of Monte Cristo", the 2002 version. I thought I'd post it because it really stood out to me:

Sound Doctrine Conference
I'm currently at the Sound Doctrine Conference, a conference on the Second London Baptist Confession of Faith, at the Brown's barn. The conference is about a week long. James Fletcher, Jake Dohm, and I have been running sound in the back. We have a table where all of us are working, and since we all have Macs, it's pretty hilarious to see al four of them lined up on the table. It's been fun, but also really tiring at the same time. I'm SO glad that today the conference ends at 6:00. Here are some pictures we took of our "work station."
James Fletcher's Mac
The soundboard, where we do all of our recording.
The awesome line-up of Macs!
The piano that's right behind us.
The gateway to the good life.

Do you believe in Santa Claus?
Now this is a really funny article I came across about Santa Claus. I know most of you, and I hope all of you, don't believe in him, but if you still do, (yikes!), READ THE TEXT BELOW. Actually, even if you don't believe in him, (hooray for you!), you can still read it. :D
Santa Claus: An Engineers Perspective
I. There are approximately two billion children (persons under 18) in the world. However, since Santa does not visit children of Muslim, Hindu, Jewish or Buddhist religions, this reduces the workload for Christmas night to 15% of the total, or 378 million (according to the Population Reference Bureau).
At an average (census) rate of 3.5 children per house hold, that comes to 108 million homes, presuming that there is at least one good child in each.
II. Santa has about 31 hours of Christmas to work with, thanks to the different time zones and the rotation of the earth, assuming he travels east to west (which seems logical). This works out to 967.7 visits per second. This is to say that for each Christian household with a good child, Santa has around 1/1000th of a second to park the sleigh, hop out, jump down the chimney, fill the stockings, distribute the remaining presents under the tree, eat whatever snacks have been left for him, get back up the chimney, jump into the sleigh and get on to the next house.
Assuming that each of these 108 million stops is evenly distributed around the earth (which, of course, we know to be false, but will accept for the purposes of our calculations), we are now talking about 0.78 miles per household; a total trip of 75.5 million miles, not counting bathroom stops or breaks. This means Santa's sleigh is moving at 650 miles per second --- 3,000 times the speed of sound. For purposes of comparison, the fastest man-made vehicle, the Ulysses space probe, moves at a poky 27.4 miles per second, and a conventional reindeer can run (at best) 15 miles per hour.
III. The payload of the sleigh adds another interesting element. Assuming that each child gets nothing more than a medium sized Lego set (two pounds), the sleigh is carrying over 500 thousand tons, not counting Santa himself. On land, a conventional reindeer can pull no more than 300 pounds. Even granting that the "flying" reindeer could pull ten times the normal amount, the job can't be done with eight or even nine of them--- Santa would need 360,000 of them. This increases the payload, not counting the weight of the sleigh, another 54,000 tons, or roughly seven times the weight of the Queen Elizabeth (the ship, not the monarch).
IV. 600,000 tons traveling at 650 miles per second creates enormous air resistance --- this would heat up the reindeer in the same fashion as a spacecraft re-entering the earth's atmosphere. The lead pair of reindeer would absorb 14.3 quintillion joules of energy per second each. In short, they would burst into flames almost instantaneously, exposing the reindeer behind them and creating deafening sonic booms in their wake.
The entire reindeer team would be vaporized within 4.26 thousandths of a second, or right about the time Santa reached the fifth house on his trip.
Not that it matters, however, since Santa, as a result of accellerating from a dead stop to 650 m.p.s. in .001 seconds, would be subjected to centrifugal forces of 17,500 g's. A 250 pound Santa (which seems ludicrously slim) would be pinned to the back of the sleigh by 4,315,015 pounds of force, instantly crushing his bones and organs and reducing him to a quivering blob of pink goo.
Therefore, if Santa did exist, he's dead now.

Updating my RAM
So today, I worked on a fun project, replacing my RAM. For those of you who don't know, RAM stands for Random Access Memory. The easiest way to explain what RAM does is that is makes the overall experience on the computer faster and much more enjoyable.
Anyway, I took some pictures of the inside of my MacBook Pro and thought that I would share them with you.
The RAM.
The SSD (Solid State Drive)
And the entire inside.
Now, my computer is way faster. And it was pretty fun being able to see the inside of my MacBook Pro.
Stand Strong,
Stephen
