Mickey is in town

Posted: June 7, 2009 at 2:56 pm

So my life is being owned by Disney at the moment. It would be super sweet and awesome if Nathan hadn’t turned “Team Awesome” into “Team Quarantine”

Everything is going decently well so far, but we are only a week in. You can wander along over here (Edit: link removed due to threats by Mickey’s lawyers. They’re a grumpy lot!) to stay on the “fringely-to-date” for everything we are doing. Yeah that’s right - it’s hosted on Disney’s servers. I’m important now. I don’t know if there will be spots for us to upload our progress later on or whatever, but that’s kind of home base for now.

The real reason I showed up was to share a MEL script I just had to write for some asset management yadda yadda yeah nobody is still paying attention anymore. The script returns the scene filename and removes the _mb or _ma at the end. Now you can quickly name nodes after the scene! Word.

string $currentScenePath = `file -q -sn -shn -wcn`;
$currentScenePath = startString($currentScenePath, size($currentScenePath)-3);

If you are working on filenames that are longer than mb or ma - just change that 3 to a 4. Simple.

Momentous Day

It took me 23 years, 1 month, and 8 days to finally realize why they switched the l with the r in the term “Engrish”

I feel like I failed humanity on some level.

Dubai

Posted: April 8, 2009 at 7:15 am

An article about the dark side of dubai. I’ve heard snippets of stories like this before, but this is a really amazing all encompassing article. Extremely well written, many different angles, and covers some important things too. The author does interject personal opinion, but I think in most cases he uses it as a tool to further investigate. Just read it!

Probably not what you expected.

It’s all about the nod at the end. You can tell he was into it.

Why reading the instructions helps

I just spent 3 days working on a broken RIB file exported out of Maya for rendering and shading. Turns out….we don’t have to turn in the RIB file…probably for this exact reason.

Controlling After Effects Expressions

Posted: March 9, 2009 at 3:20 am

So lets say you want to write an expression in After Effects that maybe….randomizes an exposure effect……but you only want it to happen for a certain duration. Whatth’eckdoyado?

if (time >= key(1).time&& time<=key(2).time) {
random(50,100)
} else{
value
}

Put that expression in, and set two keyframes for the variable it is controlling, and bingo bango - you’ve got an expression that runs only between keyframes 1 and 2!

The Universe is a Hologram

Posted: January 16, 2009 at 4:16 pm

According to some scientists, our universe could be just a giant hologram. A very interesting read, though a bit tough to wrap your head around.

I find it incredible that science has come far enough to detect this kind of stuff. Trying to put into words as best I can: I personally always thought it was strange that not everything is discrete. I feel like the Universe is one giant computer that is infinitely fast but has to be able to calculate how everything interacts. Though I was just thinking (if my understanding of the article is correct):

What if you had a particle moving at 1 meter for every “frame” of time (given time is discrete instead of continuous). Now as this particle is moving it encounters an object that is .5 of a meter thick, and happens to be located between these two “frames” of time. Does the collision not get “calculated” and the particle passes straight through the surface? Could this hitting and missing be another mechanic behind heat and light diffusion?

You encounter this situation in computational dynamics all the time. One of the most miserable things to deal with is interpenetration of your objects (clothing going through a mesh, particles slipping through surfaces, soft/rigid bodies clipping each other and going haywire). Here is an example of what I’m talking about. The guy would be the “particle” and the fence would be the “object” In reality the guy’s head should bounce off the wall, but instead goes through the wall. The first collision calculated is when his head is already halfway through the fence. If he were moving much faster or his body incredibly small it’s very likely he would have flown through the fence. This is possible simply because there is a discrete time in games (either 1/30th or 1/60th of a second). Since they are saying that our universe’s time is also discrete (though much much higher resolution), I would think the same phenomena could possibly happen in real life.

How Porsche Hacked The Financial System

Posted: January 13, 2009 at 2:39 am

Adolf Merckle, one of the world’s richest men, committed suicide yesterday by throwing himself under a train, Bloomberg reports. Financial difficulties, and particularly great losses he suffered on Volkswagen stock, are being cited as the key reason he ended his life:

[Merckle's company] VEM was caught in a so-called short squeeze after betting Wolfsburg, Germany-based Volkswagen’s stock would fall. Merckle lost at least 500 million euros on the bets on VW stock, people familiar said on Nov. 18. VEM lost “low three-digit million euros” on VW stock, the company said in November.

A “short squeeze” sounds inconspicuous enough; you wouldn’t tell it by Bloomberg’s language, but Merckle’s Volkswagen bet lost out to one of the most masterful hacks of the financial system in history.

For those of us who don’t live and breathe finance, this is that story.

● ● ●In 1931, Austro-Hungarian engineer Ferdinand Porsche started a German company in his own name. It offered car design consulting services, and was not a car manufacturer itself until it produced the Type 64 in 1939. But things got interesting for Porsche long before then.

In 1933, he was approached by none other than Adolf Hitler, who commissioned a car designed for the German masses. Porsche accepted, and the result was the iconic Beetle, manufactured under the Volkswagen (lit. “people’s car”) brand. Today, Porsche’s company is one of the world’s premier luxury car brands, while Volkswagen (VW) is itself the world’s third-largest auto maker after General Motors and Toyota.

Three years ago, Volkswagen found itself fearing a foreign takeover. Porsche, the company, decided to step in and start buying VW stock ostensibly to protect the landmark brand, widely fueling market expectations that it would eventually buy Volkswagen outright. Of course, this isn’t quite what came to pass.

For three years, Porsche kept accumulating VW stock without telling anyone how much it owned. Every time it purchased more, the amount of free-floating VW stock would decrease, driving the stock price up slightly; your basic supply and demand at work. Eventually the share price became high enough that, to outside observers, it wouldn’t have made any sense for Porsche to buy Volkswagen. It would simply have cost too much.

To explain what happened next, I’m going to first tell you about a financial maneuver called shorting.

● ● ●At any given point, only a certain amount of a publicly traded company’s stock is floating freely in the market. The rest is held in various portfolios, funds, and investment vehicles. Now, everyone’s familiar with the basic idea behind the stock market: you buy stock when it costs little, and you sell it when it costs a lot, profiting on the difference.

But that assumes a company’s value is going to increase. What if, instead of betting a company will go up, you want to make money betting the company will go down? You can — by selling stock you don’t own.

Say you borrow a certain amount of stock from someone who already owns it. You pay a fixed fee for borrowing the stock, and you sign a contract saying you will return exactly the same amount of stock you took after some amount of time. So, you might borrow a thousand shares of Apple stock from me (I don’t actually own any, but play along), pay me $100 for the privilege, and sign an obligation to return my stock in 3 months. At the time, Apple stock is worth $10 per share.

After you borrow the stock, you immediately sell it. At $10 a share, you get $10,000. Two and a half months later, another rumor about Steve Jobs’ health sends AAPL crashing to only $6 per share for a few hours, so you buy a thousand shares, costing you $6,000. You give me back those shares. Because you successfully bet the company would go down in value, you earned $4,000 minus the borrowing fee. This is called short-selling or shorting the stock, and the downside is obvious: if your bet was wrong, you would have lost money buying back the shares that you have to return to your lender.

● ● ●Now things get kinky.

When Volkswagen’s share price exceeded the point where it made sense for Porsche to buy the company, a number of hedge funds realized that Volkswagen shares have nowhere to go but down. With Porsche out of the picture, there was simply no reason for VW to keep going up, and the funds were willing to bet on it. So they shorted huge amounts of VW stock, borrowing it from existing owners and selling it into circulation, waiting for the price drop they considered inevitable.

Porsche anticipated exactly this situation and promptly bought up much of these borrowed VW shares that the funds were selling. Do you see where this is going? Analysts did. According to The Economist, Adam Jonas from Morgan Stanley warned clients not to play “billionaire’s poker” against Porsche. Porsche denied any foul play, saying it wasn’t doing anything unusual.

But then, last October 26th, they stepped forward and bared their portfolio: through a combination of stock and options, they owned 75% of Volkswagen, which is almost all the company’s circulating stock. (The remainder is tied up in funds that cannot easily release it.)

To put it mildly, the numbers scared the living hell out of the hedge funds: if they didn’t immediately buy back the Volkswagen stock they were shorting, there might not be any left to buy later, and it isn’t their stock — they have to return it to someone. If their only option is thus to buy the VW stock from Porsche, then the miracle of supply and demand will hit again, and Porsche can ask for whatever price it wants per VW share — twenty times their value, a hundred times their value — because there’s no other place to buy. They’re the only game in town.

And that, my friends, is called a short squeeze.

● ● ●Porsche’s ownership disclosure sent the hedge funds on such a flurry of purchases for any Volkswagen stock still in circulation that the VW share price jumped from below €200 to over €1000 at one point on October 28th, making Volkswagen for a brief time the world’s most valuable company by market cap.

On paper, Porsche made between €30-40 billion in the affair. Once all is said and done, the actual profit is closer to some €6-12 billion. To put those numbers in perspective, Porsche’s revenue for the whole year of 2006 was a bit over €7 billion.

Porsche’s move took three years of careful maneuvering. It was darkly brilliant, a wealth transfer ingeniously conceived like few we’ve ever seen. Betting the right way, Porsche roiled the financial markets and took the hedge funds for a fortune.

Betting the wrong way, Adolf Merckle took his life.

Spotify

Posted: January 3, 2009 at 4:41 pm

Spotify seems like it should be quite useful - maybe not for everyone - but definitely for people who like to find new music. iTunes and Amazon Music have been fairly good at that in the past, but this seems like a much quicker, more seamless, and more satisfying experience. Since the loophole to sign up may be closed at any moment go sign up NOW (instructions in the top comment at that link).

Songs play as if they are locally stored (I’m literally amazed how fast it goes) - you have access to the full track (not just a sample!) - and you can fast forward through a track with zero slowdown. More amazingly - they have a HUGE selection of artists. I actually found Tycho(!!) which is a testament to their library. It doesn’t have some

Back before Napster was introduced you had to search Ftp indexing websites that were full of dead links (kinda like a really really crappy stripped down Google). It often didn’t come up with what you were looking for, and if it DID usually the file was gone or corrupted. Napster completely revolutionized that - all the files were real, easy to find, and quick to download. It’s not quite the same, but I feel like this is almost as big of a step forward as Napster was.

Now if only I could get this on my iPod there would be no reason to save files. Until then…..
