My upgrade to Adobe Photoshop CS5 on OS X 10.6 (Snow Leopard, 10.6.3) has been a complete shambles. Any operation involving writing to the temporary disk like “Save for Web & Devices” would only result in an error dialog reading “The operation could not be completed: A write permissions error has occurred”.

Also, on exit, CS5 would reliably crash with the error: “Could not save Preferences because the file is locked or you do not have the necessary access privileges”.

Fortunately, I’m not the only early adopter suffering from this problem. The issue appears to be that Adobe’s DMG installer incorrectly sets some permissions under ~/Library/Preferences.

What cleared up this issue was executing the following command ( in Applications -> Utilities -> Terminal ).

sudo chmod -R u+w ~/Library/Preferences

These are the specific directories that were errantly set to read-only after my CS5 install.

~/Library/Preferences/Adobe/Extension Manager\ CS5
~/Library/Preferences/Adobe Photoshop\ CS5\ Settings
~/Library/Preferences/ExtendScript\ Toolkit

CNet has an article mentioning other directories that can sometimes be affected. So, if setting only Preferences didn’t work, you can try the following.

sudo chmod -R u+rw ~/Library/Application\ Support
sudo chmod -R u+rw ~/Library/Adobe

I got the dreaded “TextMate is an application downloaded from the Internet” error again after manually upgrading to the latest version on Snow Leopard.

The fix is quite simple, but rather hard to find in the first page or so of Google results. All that’s required is a single xattr.

sudo xattr -d com.apple.quarantine /Applications/TextMate.app

Last week, my favorite financial anarchist, Max Keiser ripped apart the business model of Zynga’s Facebook virtual currency comparing it to that of his archnemesis, Goldman Sachs.

Zynga is giving away Farmville dollars as a promotion for people shopping for vegetables at supermarkets. So, if you buy a zuchini at the supermarket, you get Farmville dollars which is a virtual currency which you can then use in Farmville on Facebook to grow virtual vegetables. Those vegetables trade on the Zynga virtual cash exchange for hard US Dollars. That’s a naked long.

So, the spread between naked short sales and naked long sales is enormous. A naked short sale of a credit derivative makes Goldman Sachs billions where a naked long sale of a virtual vegetable on Farmville makes somebody two dollars. The naked credit default swap is worth about the two dollars it takes to print nonsense on a piece of paper. The naked long virtual Farmville currency is worth two dollars in hard money after you spent 20 hours viewing ads on Facebook. So, why are the naked long people making $2 for twenty hours viewing ads, and the people at Goldman get two billion dollars for manufacturing credit default nonsense because they’re hooked into the US Government.

Keiser has the uncanny ability to zoom out to a macro view of the economy which reveals nothing more than a bunch of unevolved apes playing petty power games amongst ourselves. However, he makes a good point in that we are tending to stray away from our meritocratic roots in favor of a system based on cronyism, nepotism and outright fraud through naked short selling.

On the other side of the blogosphere, David Harvey has spent years promoting the idea that the capitalist system has mainly become concerned with creating money out of money. Keiser’s views on the Facebook/Zynga virtual economy fits in with Harvey’s theory. Essentially, these fictional markets are really just imaginary stopgaps so we can all pretend that we’re achieving the 3% growth per year to keep the wheels from falling off the status quo.

Keiser calls these fictional markets a zombie economy. Whether you’re an individual trading virtual goods over the Internet or an investment bank selling derivatives of derivatives of insurance on derivatives, you are participating in a fictional market where what’s being bought and sold has no actual value. The virtual goods are just as worthless as the mortgages written and sold to finance now empty houses built in Detroit during the housing boom. While online virtual markets are more benign ecologically than zombie housing, both are socially and economically useless and attempts at feigning wealth.

In the 1500′s, the Spanish learned this lesson the hard way. They conquered parts of the New World and imported tons of gold from their adventures. The biggest tangible result of this effort was that people in Spain owned more physical gold which caused 300% inflation. The general thinking is, if economic advancement isn’t backed by real innovation and improvements to the society at large, all you’re really doing is pretending to be wealthy.

Ultimately, creating virtual currencies and goods, fictional markets and zombie economies are equivalent to expropriating gold from tribal nations, printing dollars, or betting against credit default swaps. These are all misguided attempts by poorly evolved mammals at being acquisitive and maintaining power. If things proceed as they are, we will continue moving away from production, thrift, and savings towards a post-economic economy where all goods and money are virtual and nothing real is really worth owning.
