The land of good Chinese food

I'm sitting in the airline lounge in Hong Kong, slurping noodles and waiting for my flight back to the US. This was my first visit to China, and perhaps it is apt that I started in Hong Kong and then across Shenzhen Bay to the first region that benefited from the economic opening.  And benefited, it has.

Shenzhen is vibrant, in every sense of the word. The buildings are tall, the streets are clean and people are busy. It is closer to the wide-open parts of Europe (Estonia, say) than to other developing countries like India. The fourth biggest city in China, Shenzhen, beats Delhi or Bangalore on pretty much any measure.

The most surprising thing to me about Hong Kong is how green it is.  The picture you have of Hong Kong (at  least the picture I had before coming) was of Hong Kong Island.  But Hong Kong is not just that one island. It also comprises quite a bit of Kowloon peninsula.  And the peninsula is full of hills and completely wooded. Hong Kong, in other words, could have sprawled Phonex-style, but they have done the smart thing and remained compact.

This is the ferry that takes you from Hong Kong Island to Kowloon.  Pretty cool ride.  You can also take the metro, but the metro is not as cool.  It is, surprisingly, also more expensive.


Hong Kong is most famous for its shopping. America, however, spoils you because nowhere else do you have the selection or the prices that you have in pretty much any medium-sized city in America. So, it was more amusing than anything to see people lining up to enter a handbag store:
It is not just handbags, of course. I have not seen as many ads for luxury watches than I saw in Hong Kong. I used to think the Lake Geneva was quite tacky with huge signs representing different watch brands, but Hong Kong beats it in sheer quantity.  Wonder who buys all those watches. When I mentioned the watch ads to my Chinese hosts, one of them pointed to his smartphone ("who needs watches any more?") but the other one said that she was wearing a Swiss watch. So perhaps every Chinawoman will one day own a Swiss watch, and these ads are simply fighting for that market share.

The night-time view of Hong Kong Island from Kowloon makes Manhattan look provincial.

I was visiting China to visit the Shenzhen meteorological department and Sunday happened to be "open" day.  These are Chinese citizens visiting the observatory.  The TV screens with familiar weather forecasters reading the forecasts were the big draw.


The radar in Shenzhen is atop the observatory. In fact, the observatory was specially built to house the radar. The building has 15 floors, but the floors are 30-40 feet tall. So, with their high ceilings, the office spaces feel light and airy.  Before they moved here, the meteo department was in what is now the second tallest building in Shenzhen:


The hospitality was astounding. When we have visitors to NSSL, we may do one dinner with the visitors at a local restaurant. Here, one or the other of my hosts accompanied me at lunch and dinner each and every day. I told them at the outset that I loved food, was not picky and as long as they chose food without beef, I would be quite happy. They seemed thrilled that I ate with chopsticks and that I would eat fish with bones.

I also told them about cooking my way through Fuschia Dunlop's book on Sichuan food. "An English book," waved one of my hosts dismissively.  But he was from Sichuan and so he had to show me what real Sichuan food tasted like.  Off we went to a gourmet Sichuan restaurant.  That clothesline-type thing in the picture are cold cuts.  The noodles and vegetables were awesome. I think I come close in how my noodles taste, but the variety and taste of Chinese food in China is simply incredible. Chinese food in America doesn't hold a candle to this. Even the supposedly authentic Chinese places are poor echoes of Chinese food. I wonder how Chinese people can stand it (perhaps, they get served proper food when they visit and I get crap because I am not Chinese? -- I know that I can get proper Indian food at Himalayas, a local Indian restaurant in Oklahoma, but what they normally serve in their buffets is creamed-up junk).


Close to the observatory is one of the largest parks in Shenzhen. It was built for some flower expo and consists of houses similar to what you will find in different provinces of China.  A very cool park, and I took advantage to people watch in the mornings ...

The really cool thing was that people would "walk" their birds and hang them from trees.


One evening, I went to Darfen "village", a colony of painting shops. I had read about it in the NY Times a few months ago and thought it would be cool to get an oil painting of the family done.  Turns out, though, that it is the completely wrong mix of convenience, price and quality.  The painting would take two weeks to do (so it would have to mailed to me), would cost about $300 and consist mainly of transferring the photograph to canvas.  The examples they showed looked nothing like paintings -- the art was lifeless and failed to capture the spirit of the subjects.  There is no point to a low-quality painting -- I might as well hang a high-quality photograph -- and so I decided to not get a painting done.


With my work mostly complete, I had a day of looking around in Shenzhen. Unfortunately, the city is only 30 years old, and so there is nothing historic here.  The best option was "Splendid China", a theme park that  has small models of architecture from all over China.  A little cheesy, but it was perfect for me, with my passing acquaintance of Chinese provinces and building styles.

The entrance to the park has these three "gods" reflecting Chinese aspirations. The first one is the god of family, the second the god of wealth and the third the god of long life.  And I think that order is roughly right, because nothing provoked as much admiration in China as the size of my family -- two children!, everyone remarked, one boy and one girl. Put together those characters mean the word "good". Very fortunate, etc.  etc.


 All the Chinese forecasters and scientists had exactly one child each, of course.  We seem to take for granted that this means that the population of China will slope gently downward in the next few decades and so the demographic dividend will lag behind that of the United States (or India) whose populations are yet to peak. I think we are mistaking quantity for quality.  I observed that, because they have only child, Chinese parents pour all their hopes and resources into that one child. Get ready for a generation of extremely well-educated, well-rounded children.  Good for the world as a whole, but it is going to be a tough country to compete against.  Think South Korea, but more focused, militaristic and ten times as large.

Any way, back to the theme park. There was a quite a bit of Tibetan stuff there, placed in the context of grottos and Buddhas from other provinces in China. The subtext here was quite clear.




They also had quite a few shows of minority (i.e., non-Han) peoples. The subtext here seemed to be that these were primitive peoples practicing primitive religions and lifestyles.  Maybe it is even true.



The last evening in Shenzhen, one of my hosts (who is from Guanxi) decided that he had to introduce me to food from his hometown. We went to a restaurant that sourced all its food from that province. In other words, they did not shop the local markets. They got all the fish and meats and vegetables from Guanxi to Shenzhen. And yes, the food was delicious.


But the really interesting thing was the ordering of the food. We ate in a private room (Chinese restaurants have huge halls, but they also have dozens of private rooms, and most companies get one of these rooms for their groups. As far as I could tell, there was not a significant price difference between eating in a hall and eating in a private room). But we had to go downstairs, to where the food was kept and select the fish and vegetables and tell them how we wanted it cooked.  Selected fish would get whacked right there. The manager would write up a bill and then as the food got served, it would get crossed off the list.  The cost of a dinner for five with about a dozen dishes ran to about sixty US dollars.


All in all, in less than a week in China, I got to taste five different Chinese cuisines -- Cantonese (mostly steamed), Guangdong (cooked in meat fats), Mongolian (mostly grilled), Sichuan (mostly pickled-peppery) and Guanxi (cooked in mild sauces). I could live in China forever for the food -- the US now feels like the land of bad Chinese food ... but then you also quickly notice the drawbacks of living in China. No, not the pollution. It rained like crazy while I was there, so the air was quite humid, but clean. There was the time when one of my colleagues posted a link on Facebook to a New York Times op-ed about being a woman programmer and I found that I could not access it.  I could not access any New York Times article while I was in China. It was only when I was back in Hong Kong that I could read even that rather innocuous article.



Interesting story about the rain photo (above), actually.  The colleague who had taken me to Splendid China resolutely kept his phone-camera pocketed for over two hours. Meanwhile, I had taken about 200 photographs.  But the rain moved in, and out came the camera.  Weather geeks!  They are the same every where.

Casually full of verve

JK Rowling's first book after the Harry Potter series, Casual Vacancy, seems to be getting rather poor reviews. I think it may be all the new adults expecting the author they grew up with to remain stuck in the School of Magic.

As someone who found the Harry Potter books rather juvenile (of course! consider their audience), her new book was an eyeopener. JK Rowling can write! And make trenchant observations. The Casual Vacancy somehow rises past its rather humdrum plot to become a story of what life is like in the 21st century.  It brings to mind the great English novels -- the Victorian ones, with their large casts, careful plots, observations about the fine distinctions of class and Dickensian morals. Except that it has been updated for modern Britain. But you will recognize America in there too. All rich countries these days are alike.

Highly recommended.  It is high literature that manages to point at the injustice of modern life while always remaining a very entertaining read.

Interesting geography

Would you buy airline tickets from this travel agency?


If their map is to be believed: buy tickets to London, and they'll send you to a spot in the ocean a wee bit off Cape Town.

Limits are counterproductive

I am going to be teaching a course on spatial programming next semester and was dawdling around the internet looking for books on the topic. I found a book by Esri Press that looked very promising and decided to see if there was some sort of educational discount on it.

There was. In fact, they would send me the book for free if I told them the course number that I was evaluating it for.

I went to type in the details on the web form and found a statement that free samples were "limited to three books once every 4 months."  What would you do in that situation? Me? I went through the catalog and found two more books that would be kinda useful. One was a prerequisite for my course and the other would be advanced topics for it.

This is, of course, the same reason why putting up a speed limit sign can be counterproductive. Instead of taking it as a maximum speed, many drivers will treat it as a suggestion of what speed they ought to be
driving.  Esri, I am sure, will be giving away far fewer books if they took out that limit on the number of books (or at least informed piggies of the limit only if they tried to order more than three).

Schizophrenic weather

The weather forecast for today evening:


Until 7pm, we're going to have spring-time severe weather. Huge hail balls in Western Oklahoma (not so much in Norman).

Then, a cold front moves in.  By midnight, we should be enjoying freezing rain and sleet.

Fun, eh?

Anindya Das


"Live as if you were to die tomorrow. Learn as if you were to live forever," said Gandhi, and there is no one I know who lived that way as much as Anindya Das. He died last week in Pondicherry. 

Anindya had been playing basketball with some kids when he collapsed on the court. He was dead by the time he got medical attention.  Anindya left behind a career in academia (he used to teach computer science at OU and UWO in London, Ontario) but decided that he could have a more sane and fulfilling life in Pondicherry.  He found a job there in a small technology company. The company, happy no doubt at getting an overqualified friendly and competent person for cheap, allowed him to build his work hours around Anindya's volunteer hours at the Aurobindo Ashram school. He taught the kids there math and volleyball and basketball.  That's where he was when he died.

Maybe because he listened so well, he picked up languages very easily. He was a Bengali who grew up in Orissa, so that got him two languages. Hindi, of course, and English. His sister lived in the former French colony of Pondicherry, so French and Tamil too. He perfected his French in France and Quebec, and picked up Arabic and Spanish along the way.  Probably a few more that I don't know about.

I am glad that our kids got to see their Uncle Andy when we went to India last summer. We'd taken a bus from Chennai to Pondicherry and he met us at the bus station. He took us swimming in the Bay of Bengal, off to dinner at a local hangout and then bought the kids ice cream. He's enriched my life immensely, but I can not help wishing, rather selfishly, that he could have been around a couple more decades -- the kids could have gotten to balance the charms of an unhurried, minutely examined, life with whatever rat race they are in.

Things I learned today

One of my young colleagues keeps a blog where she jots down research ideas (it seems to not be public, but her public blog is here). I think that's a very cool idea and thought I'd try it for a day but with a slightly different spin.  So, I decided to keep track of the things that I did not know on Wednesday but learned on Thursday.  Here's a partial list (not including things that involve other people, for privacy reasons).

(8.15am) In a Linux script, to run two processes, wait for them to finish before starting to do something else:
 #!/bin/bash
./create_train_data.sh train -ldm &
./create_train_data.sh valid -ldm &
wait
 
How could I not have known this earlier? Still, better late than never. This will cut the time needed to do some data mining work I am doing in half; I should be able to check the results of the trained algorithm after lunch instead of waiting till tomorrow.


(9.02am) Austromigration is when birds migrate within the Southern Hemisphere. There are birds in South America, that migrate within the continent i.e., they fly North for the winter!


(9.20am) One way to track the location of small birds is to attach sensors to them. GPS chips are too big and too expensive, so one device works by simply recording the time of sunrise and sunset.  How is this enough? The time in between, solar noon, tells you the longitude.  The length of day can tell you what the latitude is, although the accuracy of the latitude varies through the year (less accurate around an equinox).


(9.45am) Cornell University and the Audubon society run a citizen-bird-reporting app called ebirds which is similar to the mPING application that we created.  Birders love the ebirds app because it allows them to keep personal records, but Cornell can QC the data and provide it for scientific studies. Might be a way to validate bird density estimates from radar ...


(10.35am) People take drills way too seriously. We had an "active shooter" drill at work. This is better than a fire drill because you can simply shut the door of your office and keep working. No big deal. But then, the drill was followed by a "hot wash" where the police officer said he was impressed that the place became a ghost town. Fine. Can we get back to work now? Nope, some one had a question. And more questions. People!


(11.00am) Google Reader is being decommissioned in July.  Oh no! How am I going to keep up with my RSS feeds?


(1.15pm) Just because I think the ground clutter case was from KGYX doesn't mean it isn't really from KRLX. It might be better to more careful about such things before wasting 2 hours on debugging something that is actually working correctly.


(2.00pm) On the other hand, the process of debugging a non-problem actually led to several neat ideas that do improve the clustering algorithm (once I try it on the actual problem case). So maybe it's a good thing to be sloppy once in a while. I still have to figure out why it is not working though.
 
 (2.40pm) If a few storms are embedded in clutter, using a height-based attribute and expanding to cover the whole cluster will lead to the NN being poorly trained. Said clutter will never be removed. (sorry)

(4.00pm) When smoothing per-capita county data, a population-density-based filter size might work better.

(4.20pm) NDVI from MODIS before and after severe weather events is a good way to determine damage paths of weather events.

(10.30pm) Feedly is a worthy replacement for Google Reader.  Although I am not a fan of the wide open spaces, I will probably get used to it.

(11.00 pm) 2NT showing the minors is a wonderful preemptive overcall of a strong NT. (sorry)

(11.55pm) Jim Crow laws were actually a major economic drain on the south. "A total of four restrooms had to be constructed and maintained at significant expense in any public establishment that bothered to provide any for colored people: one for white men, one for white women, one for colored men and one for colored women."  That is from Isabel Wilkerson's "The Warmth of Other Suns".
