Cameraphone Workshop at Ubicomp

September 25, 2006 · Leave a Comment

We had a very successful workshop on Pervasive Image Capture and Sharing (PICS) at Ubicomp 2006. Cameraphone-related research from around the world.

In addition to talking about our work, we did a field trip at Fashion Island Mall in Newport Beach with ZoneTag-enabled cameraphones. Pictures are on Flickr — we had 5 groups with Flickr userids pics2006a through e. I liked ZoneTags, but I quickly got frustrated with the tagging — although ZoneTags makes it fast by suggesting tags, it’s still slow, working through the different screens and checking/unchecking tags. I quickly stopped tagging and just hit “upload.” However, this wasn’t always a good idea. Tags and title persist across images, which is both good and bad — it saves work if you are re-using tags, but it led us to mis-tag and mis-title images when we just hit “upload” and didn’t go back through the tags.

Service Trips

September 25, 2006 · Leave a Comment

On my old blog I posted a query about some companies I had run across that organized service trips overseas –doing volunteer work of various kinds. Someone who found that post asked me what I had learned, because she was considering a trip with one of the companies I listed — but I had heard nothing. So she stayed in touch and just emailed me about her trip with Global Volunteers. She was very enthusiastic about the experience (she went to rural China to teach English) and the organization.

The Fog of War

September 10, 2006 · Leave a Comment

Saw the documentary The Fog of War – Eleven Lessons from the Life of Robert S. McNamara. I’ve been meaning to see this since my trip to Viet Nam. When I was Hanoi, this was playing in the middle of the morning on the movie channel in my hotel, and I was tempted to stay in and watch it, since I realized it would help me understand Viet Nam and the war.

McNamara was Secretary of Defense, not only during the Viet Nam War. but also the Cuban Missile Crisis, and during World War II he was an officer on the staff of the general who ordered the fire-bombing of Japan. This documentary consists largely of him talking — organized around eleven “lessons” — supplemented with audiotapes of conversations (phone and meetings) of McNamara, Johnson, and others, and historic news footage.

It’s impressive to hear from someone who was not only involved in such major events, but went back later to find out more about what they didn’t know at the time, and has reflected on what he learned and reconsidered what they decided at the time. Some of the things that I either hadn’t known or hadn’t fully understood that I learned from this documentary:

  • In WWII the US firebombed 67 cities in Japan, killing 100,000 civilians in Tokyo in one night. McNamara says that they had bombers that flew low enough to be hit by anti-aircraft fire. Then B-29s flew higher, but weren’t accurate. So the general decided that fire-bombing from low altitudes would be most efficient.
    • he quotes someone — this same general, I think — as saying that, if we had lost the war, they would have been prosecuted as war criminals.
  • During the Cuban Missile Crisis, there were already warheads in Cuba, unknown to the US. McNamara later met Castro and asked if he would have advised Kruschev to use them, and he said he had. McNamara exclaimed that that would have resulted in the destruction of Cuba, and Castro said he was willing to do that. After the crisis, a US general recommended that we go in and bomb Cuba anyway, on the grounds that we would have do so sooner or later, so better sooner. What even McNamara didn’t know, but Castro did, was that we had already tried to assassinate Castro, twice.
    • One of McNamara’s lessons here is: “Empathize with your enemy.” But how can the decision-makers empathize, and predict how the other side will react, when they don’t know what the CIA is up to?
    • Another is “Rationality will not save us” — Castro was definitely not being “rational.”
    • Another lesson is: “Belief and seeing are both often wrong.”
    • He says that this is the closest we have ever come to nuclear war. I was in grade school at the time and I remember the tension, and everyone’s belief that we were on the verge of nuclear war, day by day, waiting.
  • Under Kennedy, McNamara announced that we would reduce the number of US advisors in Viet Nam (predecessors to the fighting force) and had begun the reductions. Johnson countermanded this decision.
  • I had heard that the Tonkin Bay incident, which caused the US to bomb North Viet Nam and resulted in the Tonkin Gulf Resolution giving Johnson the power to conduct the war, had never happened. We hear McNamara’s analysis, and the real-time audiotapes of the inquiry, as people in Washington try to figure out whether there was a torpedo attack on the US ship. We hear McNamara ask the captain if he’s sure there was an attack, and the captain says, “I’m sure — I think.” On that basis, we escalated the war. The evidence was sonar readings, and the interpretation of the sonar crew, but in rough water there’s a lot of noise on sonar.
    • Again — “Belief and seeing are both often wrong.” The question then is — what if you’re wrong?
  • McNamara makes it clear that people in Washington had great difficulty figuring out what was going on in Viet Nam, and how to proceed. He wanted the US to pull out. Johnson too felt that the US had no good choices, that the whole situation was a mess. But Johnson insisted that we couldn’t leave. McNamara resigned; not long after that, Johnson announced that he would not run for re-election. At this point, only half the US soldiers who would die in the war had died.
  • The documentary repeatedly, graphically emphasizes the US belief in the “domino theory.” When I was in Viet Nam, I wondered at our strong insistence on this. When in 1992 (I think) McNamara met the former North Vietnamese foreign minister, the foreign minister exclaimed that the US didn’t know Vietnamese history; theirs is a history of a thousand years of fighting for their independence from China, then from France. So they were never going to let either China or the Soviet Union rule them, and they assumed that we wanted to colonize them as France had. And that is indeed the message that I got from the history museums in Saigon and Hanoi: the long history of fighting foreign domination from all sides, especially China; the bitterness at the French domination; and the US as yet another colonial power.
    • What do we not know about Iraqi history? And how it leads them to think about us? In Rory Stewart’s book, The Prince of Marshes, he talks about driving into Nasiryah, past a statue commemorating a 1920s Iraqi uprising against the British, showing an Iraqi shooting a British soldier in the back of the head.

McNamara is asked why he didn’t publicly oppose Johnson after he left the administration, and whether he feels guilty. He refused to answer both these questions.

Your Phone Knows Your Secrets

September 4, 2006 · Leave a Comment

Washington Post article about a company that bought cellphones on eBay and resurrected the text messages on them — some of them quite embarrassing.  Erasing the info isn’t enough, it can still be read.  My phone has a place for me to enter my passwords, credit card numbers, and the like — not that I’d ever do such a thing.

Face Recognition for Family Photos

September 4, 2006 · Leave a Comment

This new site claims to be able to use face recognition on personal photos. Our research shows that, while family photos are important, people don’t annotate them. The photographer and his/her contemporaries claim they know who everyone is; and then subsequent generations end up with photos full of people they have difficulty identifying. This site seeks to solve that problem: once you label someone, it claims to be able to recognize them in other images. I haven’t tried it out.

Flickr Adds Map Interface

September 4, 2006 · Leave a Comment

You can now locate your Flickr photos on a map, and browse others’ images. Go to your account, then organize, then map, to map your photos. To see others’, go to http://flickr.com/map/.

I love being able to locate my photos on the map — I just went through and geo-located most of my images from Japan, Viet Nam, Colorado, and New Mexico. Generally it’s possible to be quite accurate, once you get down to the needed level of detail. It would be nice to be able to search on place name. For example, I know Kamakura (where I took lots of pictures) is south and west of Tokyo, but I couldn’t find it until I got to a high resolution, so had to do a lot of wandering around the map to find it, exactly. You have to know where a place is, at least a ballpark idea, to find it.

A couple of place names weren’t on the map, and I had a general idea of where they are but not specifically. For example, Sapa, Viet Nam, doesn’t show up on the map but it’s a common tourist destination, so I predict that there will be lots of pictures scattered around that general area.

Looking at other people’s images — I think that common places are going to be overwhelming. (There are already more than 2 million images geo-located; 90 for San Francisco.) For rare places, however, this could be very useful — I was looking into a trip in Western China and wanted to see pictures of the places I might go, and most tagging wasn’t specific enough. It’s possible that with this interface I would have been able to find useful images via geo-location, since I was looking at places for which there probably aren’t that many Flickr images, and to geo-locate them the owner has to pick a spot — so even if the spot isn’t very close to reality, it’ll be better than a tag like “China.”

I think it doesn’t show your own images when you look at “everyone’s” — I geo-located several in Yosemite, southern Colorado, and New Mexico, and none of them showed up when I looked at “everyone’s.”

Needed: an easy way to batch edit the images sharing a location. I accidentally labeled a bunch of photos for the wrong place (not realizing that my previous set was still selected) and I had to go find them in my larger collection to re-locate them and thereby remove them from the wrong location. In the edit function in the location interface, images are edited one at a time, and one choice is “delete” — but I didn’t know whether that would merely delete it from the geo-located set, or completely delete it from Flickr .

New Pew Report on Internet Use

September 4, 2006 · Leave a Comment

The Pew Internet and American Life Project has published a new report on US internet use.

Some key findings:

  • While 73% of American adults use the internet, that drops to 32% of those over 65.
  • More homes have high-speed access (62%) than dial-up (34%).
  • While 91% of internet users have sent email, only 8% report ever having blogged (Feb-April 2006). Thirty-nine percent have read someone else’s blog.
  • Among internet users, 66% use the internet on a typical day; 53% send email on a typical day.
  • Only 4% admit to ever “downloading or sharing adult content online.”
  • Sixty-seven percent of internet users have bought something online (as of Sept 2005).
  • Twenty-five percent have downloaded music (Dec ‘05).

Crocodile Hunter Irwin Killed in Action

September 4, 2006 · 1 Comment

Steve Irwin, the Crocodile Hunter, was killed while filming an interaction with a stingray. For those of us who’ve watched him over the years, this isn’t a surprise — I remember an episode where he went around looking at rattlesnakes in various parts of the US, and repeatedly reached into a nest to pull out a snake. Ironically, according to news reports this was a freak accident, a sting that’s rarely fatal, but the barb went into his heart.

I’m glad it wasn’t one of his beloved “crocs” that killed him.

Understanding Iraq and Afghanistan

September 2, 2006 · Leave a Comment

Whatever your stand on the war in Iraq, many of us are trying to better understand that part of the world, and the current situation. I’ve read two books recently that I find illuminating, both by Rory Stewart, a Scot who has lived in Islamic countries for 10 years and worked for the British Foreign Office:

The Places in Between: Stewarts walks across Afghanistan, in the winter, alone except for a dog he picks up along the way (which saves his life at least once), taking the least-travelled (because least-accessible in winter) route, 3 months after the US invasion. I read a review that said that “If…you’re determined to do something as recklessly stupid as walk across a war zone, your surest bet to quash all the inevitable criticism is to write a flat-out masterpiece. Stewart did. Stewart has.”

His stories of his encounters with people, both friendly and hostile, are fascinating. He is threatened with death many times (and shot at at least once). But he also encounters traditional Muslim hospitality, wherein travellers are put up and fed, and escort to the the next town. Several times he would not have made it across snowy passes without such local escorts. We also learn a lot about Islam, as well as about a part of Afghanistan where village headmen run things, and loyalties and rivalries are complex, embracing a long history of local conflicts as well as shifting loyalties toward the Russians, the Taliban, and the US. He asks people along the way about the times under the Taliban, and often reports the number of people lined up and killed for what seems to be no reason.

It’s part of a much longer walk — from Nepal to Turkey — and I hope he writes about the rest of it.

His second book, The Prince of the Marshes: And Other Occupational Hazards of a Year in Iraq, is about his year in Iraq as an official of the Coalition Provisional Authority, beginning shortly after the invasion of Iraq. Again, his understanding of Islamic society helps us to see what is going on and how inevitably clueless the occupation forces often are.

The complexity of their task is overwhelming. He’s supposed to be starting a civilian authority in conjunction with the British military forces that have been there for several months, meaning that he has to establish his authority with both the military commanders and the locals. Early on, he is given $10 million in cash to spend in a month on rebuilding projects. (He has to give back $1.5 million that he just can’t spend.) Under Saddam, food was distributed by ration cards — and he and his colleagues have to convert this to a market economy. They try to put together a governing council of local leaders, when they don’t know the local groups and individuals and have to try to figure out who actually represents some sort of constituency, who are Iranian agents, and who is anti-Coalition.

When the local police chief is assassinated, a mullah is kidnapped, and the tribal rivalries threaten to erupt into violence, he calls the leaders of the various factions together to try to negotiate peace — working through an interpreter (he speaks Persian but not Arabic) who mis-translates him.

In both books, we learn less about Stewart than about the situations in which he finds himself. He both knows a lot about the local culture, and knows that there’s a lot that he doesn’t, cannot know. He knows that there are people he can trust, and people he cannot, and we are as mystified as he often is as to who’s who. He’s at times brave to the point of being fool-hardy, but we also see that often the only way to meet his challengers is to be tougher than they are. And we see his genuine affection for the people of both countries.

Help Desk Hell

September 2, 2006 · Leave a Comment

From today’s NY Times:

Help Desk Hell Half of corporate information technology managers in Britain have so much contempt for their users that they deliberately sabotage them, according to SkillSoft, an online training firm.

Those systems managers admitted to being “unhelpful and/or obstructive” to their users, according to a study commissioned by SkillSoft (pcauthority.com). Not surprisingly, the same share — 50 percent — of I.T. managers are actively looking for other jobs.
