Onion Futures Act

I'm not making this up: http://en.wikipedia.org/wiki/Onion_Futures_Act This law is notable as the first and only ban on the trading of futures contracts of a specific commodity in United States history, and as a unique modern case with which to study the effects of the existence of an active futures market on commodity prices. I'm sure a more skilled comedian could come up with a good joke about The Onion, or build on the famous Simpson's reference .

Forbes on Disclosed to Death

Forbes Magazine has a nice article arguing that more disclosure isn't necessarily better , pointing out the complexity, the difficulty in making choices, and the legalese. My favorite passage: One study found that despite the [Miranda] warning the overwhelming majority of suspects (78% to 96%) waive their rights ... "Next to the warning label on cigarette packs, Miranda is the most widely ignored piece of official advice in our society."

Four papers accepted to Ubicomp 2010

Our group had a good year for Ubicomp with four papers accepted, all on various aspects of privacy, location, and social networking. Jialiu Lin, Guang Xiang, Jason Hong, Norman Sadeh. Modeling People’s Place Naming Preferences in Location Sharing. This paper looks at how people name places when sharing with others. Eran Toch et al. Empirical Models of Privacy in Location Sharing. This paper examines what location information people share with others, using models of how public a place is, and how mobile that individual is. Karen Tang, Jialiu Lin, Jason Hong, Norman Sadeh. Rethinking Location Sharing: Exploring the Implications of Social-Driven vs. Purpose-Driven Location Sharing. Here, we examine the difference between two different kinds of location sharing. One is purpose-driven ("where are you now?"), the other is social-driven ("hey, I'm in Paris now"). Justin Cranshaw, Eran Toch, Jason Hong, Niki Kittur, Norman Sadeh. Bridging the Gap Between Physical Locat...

Droid vs HTC Hero

The Droid phones are really amazing in terms of functionality, though the biggest surprise for me is comparing the usability of the Droid vs the HTC Hero. I've never liked virtual keyboards, so the Droid handily wins out here for me. However, the virtual desktop feels clunky on the Droid, but surprisingly useful on the Hero. In part, this is because the Hero comes with gorgeous widgets already set on the virtual desktop, providing easy access to photos, calendar, messages, and so on. These widgets are also far more useful than others I've looked for in the Android marketplace. (I poked around to see if I could transfer the HTC widgets over to the Droid, but alas! It looks like these widgets requires additional software in the background. I'm hoping HTC will sell their widgets on the Android marketplace, but I doubt it since their goal is probably to differentiate their product so as to sell more hardware). At any rate, if anyone knows of a good calendar app for Android, ple...

Why Do Organizations Purchase Security Software?

After presenting at the ISSA CISO forum , I got into this really interesting discussion as to why corporations purchase security software. Given that I've been struggling to understand why technologies are and aren't adopted (especially those from the CHI community), I was naturally intrigued. The manager of Schlumberger's enterprise services security listed three reasons: There was a recent security incident There is a new regulation or policy in place The organization failed an audit recently I'd add a fourth one, which is that everyone else is doing it. These days, people purchase firewalls, spam filters, and anti-virus software almost as a matter of fact.

Android SD Card Mounting

Note to self: to view the contents of the Android SD card on a PC, you plug it into the USB port and then in the Android notifications screen, choose to Mount it. Once you do this, though, you can't read or write to the SD card on the Android phone itself until it is unmounted. Total elapsed time to figure this out: 46 minutes.

Interesting Facebook Authentication

I just logged into Facebook while in Brazil, and was presented with an interesting challenge-response. Apparently, FB is doing some kind of profiling as to where you login (or alternatively, where lots of fake logins are happening). After answering a captcha, I was presented with a series of photos from my friends list, and had to answer multiple choice questions, getting at least 4/7 correct. I thought this was a compelling idea. The photos would be relatively hard for attackers to find, and not too hard for the owner to identify (unless you're one of those people that friend everyone they meet).
