2013 is very soon!

In 2013, BMW will start selling a production version of its i3 concept car, which can drive itself at speeds of up to 25 miles per hour.

Relevant to my research:

If 1 percent to 5 percent of cars can send real-time data about their speed to a central hub, traffic jams can be spotted within five minutes, and cars equipped with GPS systems can be offered alternate routes to avoid them.

Some day in the future when you drive onto a superhighway, you’ll reach over to your dashboard and push the button marked “Electronic Drive.” Selecting your lane, you’ll settle back to enjoy the ride as your car adjusts itself to the prescribed speed. You may prefer to read or carry on a conversation with your passengers—or even to catch up on your office work. It makes no difference for the next several hundred miles as far as the driving is concerned.

Such insight! Autonomous driving (on highways) as seen from 1958!

Viewpoints: Is high-speed rail the transport of the future? – Viewpoints – The Sacramento Bee

While high-speed rail is the right technology needed to modernize California’s transportation network today, by the time the project overcomes state government bureaucracy, settles inevitable lawsuits, identifies the necessary funding, and completes construction, it may no longer be the most modern, efficient, cost-effective and environmentally friendly transportation technology. By that time, the answer may very well be the self-driving car.

Utilizing existing infrastructure when constructing more is expensive in both time and money always seemed so obvious. This no doubt comes directly from the software “lifestyle” I come from. Code it, compile it, run it, test it. This cycle process should take something like 10 seconds or possibly a week — but not months or years. We software engineers are impatient and recognize that time is a limited resource too.

Teaching English: observations

In addition to teaching 6.004 (Computation Structures) this semester, I was also a volunteer ESL instructor to Chinese immigrants with a Harvard student-run program called Chinatown ESL. The program, though still constantly seeking improvement (as every program should), seems very mature and effective. Its curriculum is divided into 5 levels, with the first level assuming no English background whatsoever and with the last level entirely taught in English. The classes are also split into Mandarin or Cantonese versions. I taught the first level alongside my co-instructor Ina for 2 hours every weekend, and it not only gave me another perspective on teaching and an opportunity to practice my Chinese, but it was an entirely rewarding experience on its own.

Student demographics
The students were in the age range of 30-80, though they would occasionally bring their grand/kids. They were all somehow affiliated with the Boston Chinatown community. The male-female distribution was roughly uniform, perhaps leaning a bit towards more females. My guess is that most of the students were parents. Some of them were taking the class (Level 1) for the first time, but a number of them were taking it for the second or third time. The spread of English background was fairly wide. A number of students probably could have attended a higher level, but insisted that they had forgotten all of their English and wanted to “start over.”

Handouts
Like my 6.004 students, these students also had a predilection towards handouts. The difference, however, is that the handouts we used in this class were mostly homework assignments, quizzes, and practice sheets — rather than colorful explanations of concepts. But the effect was all the same because these students really appreciated any additional practice they could have on their own. In other words, they loved homework! One student would attend another class (at the same time), but then would stop by my class at the end to request a handout and turn in my class’s homework!

On the other hand, we also gave them verbal and oral homework — namely, to find a person on the street and have a short conversation, or to listen to an audio CD and read along in the textbook. We have no way of checking whether they actually followed through, and my hopes are not high because they expressed several times how weird it would be to do so. Which makes their hyper-active participation in class even more unexpected.

Active participation
A sharp contrast to my 6.004 students, my English students will not hesitate a single moment to voice their opinions on my teaching style, the lesson content, the teaching atmosphere, the number and speed of handouts coming around, the difficulty of the quizzes, etc. They will ask questions, add their own commentary, and even help with our Chinese (when it’s lacking). They will speak up without being prompted, and it would often take us some time to get them all to quiet down so that we can actually start or resume teaching. Aside from the part where it is sometimes difficult to teach over 10 other voices, I am not at all suggesting that their is bad — rather, it just makes me so happy how active they are in their learning. They are there for 2 hours a week, and dammit they are getting the most that they can out of it. I like that a lot.

Gratitude
To me, taking the class as seriously as they are is really a sufficient way to show gratitude. But during our last class yesterday, they really went above and beyond. Last week, we suggested that they bring some food to share during the last class, so yesterday we had an amazing potluck of authentic Chinese food. Many of them made their dishes from scratch, including Tofu Skins (豆腐皮), which just seems ridiculously difficult to make, and Beef Shins (牛腱) perpared in an amazing manner like my parents used to. They would continue to gently (or not-so-gently) encourage us to eat more, give us their thanks and appreciation, sing for us… it all reminded me of those extremely cordial meals and welcomes in China earlier this year. One by one, they trickled out, but not before helping to clean up and thanking us one last time, and we would say to them “See you next time!” one last time too.

Ina and I announced to them out intentions to teach Level 2 come next semester, and my heart just melted away when a number of them told us they would study the Level 1 material hard over the summer session and hope to join us again in Level 2.

The next DARPA challenge is also (in part) about making cars autonomous — but in a completely different way!

The not-too-distant future of driving: When cars can talk, crashes may be avoided – The Washington Post

The concept is fairly simple. All cars will be equipped with short-range transmitters that use dedicated bandwidth to send information 10 times per second about where they are and what they are doing. The transmitters also will receive and make sense of the same information from every other vehicle within range.

The car will decide whether to give a heads-up to the driver or take appropriate defensive action itself. A driver alert could be a verbal warning, a seat vibration or a slight jerk on the seat belt.

via The not-too-distant future of driving: When cars can talk, crashes may be avoided – The Washington Post.

The idea is very simple: tell a car where the cars near it are, and make sure that it is not in the same place as any of them at the same time. Safety solved, crashes avoided. What a great use of data and what a great side-effect of reliable communication.

This connected-vehicle technology could address about 80 percent … of all the unimpaired driving crashes in America

Ther will be a pilot program with 3,000 cars underway in Ann Arbor, Mich., which will hopefuly prove the reliability of the technology.

Stanford study to try cold cash and social game to relieve rush hour traffic

Sleeping in might never feel better. To lower traffic congestion and pollution, a new program seeks to get Stanford drivers to avoid arriving and departing the campus during peak hours. Professor Balaji Prabhakar aims to deliver social benefits at low cost using people’s penchant for a chance at a bigger payout over a predetermined small reward.

Gamification of traffic!

Ford is ready for the autonomous car. Are drivers? — Mobile Technology News

The auto industry has already developed all the technology necessary to create truly autonomous vehicles. The reasons there aren’t driverless cars all over the road today is in part a cost issue, but it is mainly one of driver mindset. Ford plans to change that.

via Ford is ready for the autonomous car. Are drivers? — Mobile Technology News.

Very interesting point that “inter-networking vehicles with one another and other transportation networks” in a way nulls and void the autonomy of autonomous cars, and that they will merely be automatic.

First, I’m not sure that we want full autonomy in our autonomus cars anyway. We simply want to get to where we want to go, and that is achieved through networked communication and intelligent path planning, not through autonomy.

But even more interesting, it seems that it is the driver who is more autonomous in the autonomous car. We will be freed of the time we spend guiding the wheel and the gas pedal!
