City cars

January 10th, 2010

I’ve driven many cars, but none have had engines as small as the one I am driving now: a Kia Picanto. This has a 1L engine. It has no trouble reaching 100kph on Singapore’e expressways. The interior is roomy enough to seat 5 (cooperative) adults. It has 4 doors and a hatch. The trunk is small but fine for groceries for a family of 3.

It’s also the smallest car I’ve driven. Even in the parking lots around NTU, it’s about the dinkiest car around.  Here is a photo.

The car is supposed to get 50mpg easily. I’ll report on the results I get this month.

1 Feb 2010: First tank of gas, mileage is 13.6 km/liter, or ~32 mpg.  Not as much as I would have hoped.

Why don’t we have city cars in America?

Unlocked iphone

December 19th, 2009

I bought an iPhone in the US without a contract, which requires paying full price. It is unfortunately still locked to AT&T, which means I cannot use it in Singapore. However, if I unlock it, I can use it on any network. Unlocking for personal use in the USA is not illegal, according to the exemption given to the DCMA. Since I live in Singapore, it is not clear what law applies. Anyway, if I am doing for personal use and have already paid Apple the full price of the phone, I can do what I want.

I asked a friend who has experience with this.  The process involves installing Cydia.

Anyway, thanks to my friend, my iPhone now works beautifully in Singapore. I am able to use any SIM card I like. I must say the audio quality is better than any phone I have used previously. However, I cannot update my firmware without going through the unlocking process again. I can still install apps–in fact I just installed Skype.

One annoying thing about Apple’s phone keyboard is that all phone numbers are displayed in (3)-3-4 US format.  Here in Singapore, the number are in 4-4 format, and Apple’s reformatting throws me off.  Strangely, a simple option to display numbers in non-US format is not available in any of the menus I have seen.

Afghanistan Strategy : Brief to the POTUS

November 4th, 2009

The White House Flickr stream keeps getting more interesting all the time. Here is a link to one of the best pictures Situation Room photo It’s a photo taken in the Situation room of the White House, where the President meets to plan strategy. The high resolution photograph is great. You can see, for example, the title of the document next to Robert Gates, the Defense Secretary. It says “Afghanistan Strategy : Brief to the POTUS”. POTUS is the acronym for President of the United States.  Here it is.

Internet watch

October 24th, 2009

Timex used to make an “internet watch”. It was basically a pager that also worked as a watch. The pager function updated the time automatically, so that when I travelled across time zones in the usa the watch would automatically set to local time. It also came with an email address, which was basically the pager number@serviceprovider.com. I could receive emails and scroll through them one line at a time on the watch. This was the best watch I’ve ever owned.

Unfortunately, the battery in this watch lasted only about 2 months. Each time you replace the battery, you end up further destroying the waterproof seal. The result is that humidity, sweat seep in and corrode the insides. The watch stopped worked about a year ago.

Here is the PCB inside the watch. The corroded receptable for the battery can be seen. Look for the vibrator alert, which is basically a solenoid.

iTunes does not work in Singapore?

October 24th, 2009

Strangely enough, the iTunes on my iPhone now says it does not work in Singapore. It won’t even let me download free stuff, like podcasts. This is very strange given that iTunes works on my laptop in Singapore. I can download and purchase just fine here, but only to my laptop. I googled this and found other people complaining about the same problem.

Apparently iTunes is only available in North America, Europe, and Australia/New Zealand. But it not available in Asia, though that’s where the people are.

Update: After writing this, I found a workaround.  I created new iTunes account with a US address, and when it asked for a credit card, I clicked “none”.   Then on the iPhone, I went to “settings->general->reset” and reset the location warnings.    It didn’t work immediately, but after the 1st failed attempt iTunes started to work.  I could download NPR’s wait wait don’t tell me!

YouTube vs Flickr

October 22nd, 2009

I attended a great talk by Professor Eugene Fiume on Digital Media today.  He showed examples of technically brilliant computer graphics, which as he put it, still lacks “irony”. He also showed examples of great art where there is a lot of irony despite the lack of detail or technical brilliance (a clip from the Disney movie “Dumbo” was really moving).

The talk made me think about Flickr, the photosharing site.  There’s a lot of technically brilliant photos on Flickr, which are excellent in exposure, focus, etc, but they are not that interesting.    On the other hand, YouTube has a lot of poorly lit, grainy, shaky, technically crappy videos which are very compelling.  The YouTube videos have “irony” in the Fiume sense.

Why is that? Why do YouTube contributors “get it”, while Flickr contributors don’t? Is it video vs photographs, or is it YouTube vs Flickr (the way they are organized) that matters?

Half a kilowatt

September 20th, 2009

After reading in the news that California plans to regulate the power consumption of flat screen TVs, I did a little checking on my setup. My TV, a Sony 32″ LCD, consumes 156W. My DVD player, a fairly simple Sony model, takes a miserly 9W. The power hog is my home theatre receiver. This Yamaha 5.1 channel unit consumes 530W in 5 channel, 230W if only stereo is used! And the subwoofer is powered, drawing an additional 40W. This is likely the maximum power consumption, when the volume is cranked way up. But even at moderate listening levels, the unit gives off a lot of heat. I think the DSPs on board that operate on the compressed digital audio are to blame. The idea of consuming half a kilowatt just to listen to simple movie dialogue is appalling.

William Gibson’s Pattern Recognition

September 20th, 2009

I started reading this after being taken in at the bookstore by the first page, which, as in other Gibson books, is memorable.   Here is one sentence on that page: “Nothing at all in the German fridge, so new that it’s interior smells only of cold and long-chain monomers.”

The story is about the search for the maker of “the footage”, a collection of snippets from a movie which is being released anonymously on the internet.  The snippets are released in random order.  Fans of the footage reassemble the snippets to form their own movie, applying their own pattern recognition.  This is the only book of fiction that I know of to discuss watermarking of video.

The rest of the book doesn’t live up to the first page.  In fact, it drags and is often tedious.  It would have been good to cut about 50-100 pages.    Gibson’s style is not particularly easy to follow.  It’s a lot like reading emails from a busy, self-absorbed geek.

I’ve read glowing reviews of this book and its meaning on the internet.  The book would be worth those reviews had it been better written and motivated.

Trip to Taman Negara

September 19th, 2009

Last semester, I went with the NTU staff recreation club to Taman Negara National Park in Malaysia.  The park contains a rainforest dating back over 130 million years. It is divided by rivers and contains tigers, elephants, many monkeys, and lots of monitor lizards.

The trip was as interesting as the destination.  We boarded the train at the station in Tanjong Pagar.  Though the station is in Singapore, the station itself is actually part of Malaysia.  Ditto for the train tracks. In what other country does the railway belong to another country? Therefore you go through immigration at the station, and are in Malaysia as long as you are on the train, though you are travelling through Singapore!  The train reaches the Singapore/Malaysia border at Woodlands.  There, we got off the train and went through Singapore immigration (to leave the country) and once more on the Malaysian side (to enter Malaysia).  Confusing? Yes!

The train is an older diesel locomotive, with airplane type seats and a dining car, and grody toilets.  The train stops at practically every small town along the tracks.  We reached our final stop, Jerantut, at 1 am, after 8 hours of travel, and were taken to a hotel for the night.  The next morning, we took a bus to the Park entrance.

We stayed at the Mutiara resort. It’s a luxurious (to me) resort located right at the edge of the park, actually just inside.  Among the funny quirks are that you cannot buy alchohol outside the park,  being part of the state of Pahang, which is “dry” Malaysia.  But you can buy inside the park. I guess that’s because the park is national rather than state territory.

You might think that a tropical rainforest is hot, humid, and full of mosquitoes.  Actually, it is not.  It is cooler than in Singapore, being in the shade.  It is humid for sure, but not oppresively so.  The bugs were not a problem.   I was not bitten once in the whole trip.  I think that’s because the rivers flow fast through the park, and the birds and other critters keep the mozzie population down.

The best part of the trip was the boat ride up the Tahan river.  The huge trees shade the river, and the water is cool and clear.  The guides make sure you get wet by using their paddles to spray up water.

I did have a minor medical emergency on the trip.  I slipped and fell at the entrance to the Gua Telinga cave, and had to go the Klinik for stitches.  Fortunately, Malaysian clinics are good and very cheap.  I came home with 4 stitches on my leg as a kind of souvenier.

Taman Negara is “awesome” according to the Lonely Planet guide to SE Asia. I agree.  Here are some pictures.

DLNA : Does Lots of Nothing Again

September 14th, 2009

My Samsung Innov8 phone has a feature called “DLNA”. This is supposed to let you wirelesslessly connect your TV, cellphone, and pretty much everything else that may have wifi, together. Presumably, you can show pictures or video from your phone on your wifi-equipped TV. In theory. Of course, these grand connectivity schemes never work (bluetooth?).

My DLNA client is located in the cellphone’s “Applications” folder. When activated, it says version 1.0. That should tell you what you to expect. However, the DLNA logo is prominently displayed on the back of the phone, and on the box it came in. So I decided to try it. When launched, the client asks you for your wifi network name. After 3 tries, it managed to log in. The screen showed a status message that said “server active”. Nothing else happened. None of the other menu options suggested a way to use the client. Nor was there a brochure that came with the phone to explain what to do next.  I wonder how much longer DLNA will survive as a labelled feature on cellphones: 1 more year, 2 years (my bet), or 5 years.
