Schneier Disects the TSA’s “Trusted Traveler Program”

Bruce Schneier:

I’ve already written about what a bad idea trusted traveler programs are. The basic security intuition is that when you create two paths through security — an easy path and a hard path — you invite the bad guys to take the easy path. So the security of the sort process must make up for the security lost in the sorting. Trusted traveler fails this test; there are so many ways for the terrorists to get trusted traveler cards that the system makes it too easy for them to avoid the hard path through security.

Miller on DRM Lock-in

Ernest Miller on Apple & Microsoft DRM (Digital Restrictions Management) Lock-in:

Look at it from Microsoft’s point of view. Every song you purchase from iTunes with Apple’s proprietary, DMCA-protected DRM is one more bit of lock-in to Apple. When you’ve got a hundred or two hundred or more of your favorite (let’s face it, you buy your favorites first) songs in iTunes format, you’ve got some significant lock-in in the form of very high switching costs. Just the way Steve Jobs likes it.

And that lock-in is growing at a rate of millions of songs every month.

Very useful post, Ernie!

The Tax Mess: Sticking It To Us. Presidio Fires Back

Lynnley Browning sort of misses the point of Presidio’s lawsuit against the US Government. Browning focuses on the personalities, rather than the larger constitutional question.

Presidio’s suit is an attempt to test how the tax code’s ambiguities and complexity stand up in a federal court.

It’s easy to find zero sympathy for the wealthy, however, recent tax law changes, including large corporate giveaways supported by our “populist” US Senators Russ Feingold and Herb Kohl demonstrate the problems (and opportunities) that our tax law spaghetti creates.

Growing tax code complexity simply means more opportunities for the wealthy and growing hassle for the rest of us….. Disclosure: One of Presidio’s principals is a good friend of mine.

UPDATE: Andrew Ross Sorkin takes an interesting look at a Wall Street case that NY Attorney General Eliot Spitzer lost. Sorkin digs up quite a quote from a juror:

The jury was split 11 to 1 – with all but one juror prepared to acquit Mr. Sihpol of all charges. The lone juror told reporters that she was convinced of Mr. Sihpol’s guilt because she just could not believe the government would bring a case if there wasn’t something to it.

Having said all that, if Presidio did break the law, then they will deal with the consequences. It’s difficult for me, a laymen, to understand all the nuances of our tax system. Time to start over, I think.

Concept Maps

Wired:

A research institute here is taking software designed in part to preserve scientists’ knowledge and giving it to schools around the world as a tool to help children learn.

The software was designed to literally map out what scientists know in diagram form. The Florida Institute for Human and Machine Cognition is providing the concept mapping software to individual schools as well as training teachers in Panama, the first country adopting Cmaps nationwide.
