Riding public transport

Tuesday, July 22nd, 2008

When I lived in Auckland from 1992-1999, I relied on the bus and, later, the harbor ferry to commute to work.    The ferry boat trip took just 10 minutes, but I often wished it was longer to enjoy the harbor breeze.

When I lived in Silicon Valley I spent two years commuting by public transport to work. Each morning I rode my bicycle to the Caltrain,  hopped on with my bike onto the bike carriage, and rode about 15 minutes from Sunnyvale to Palo Alto.  Then I rode 4 miles to my office.

Now that I’ve moved to Singapore, I rely on public transport. Here is a city where it is possible to survive without a car.  If I want to leave the NTU  I take the SBS bus to Boon Lay, and get on the MRT  Both are airconditioned, and neither needs a schedule. The trains run every 7 minutes from Boon Lay, and the buses at least every 10 minutes from campus.   It was amazing to me to see that none of the 30 bus lines at Boon Lay interchange shows a schedule, indicating they come frequently enough that a schedule is not needed.   Public transport in Singapore is  cashless: rides are charged to your EZlink card, which is contactless, using RF at 13.56 MHz.  The card works within 3 cm, so you can keep it in your wallet.  The card costs S$15, and comes with a S$7 credit to start.  You can top up the EZlink at any MRT station. It typically takes me around S$2 to travel across town on a combination of buses and MRT.

Moving to Singapore

Saturday, July 19th, 2008

About 4 months ago, I decided to move to Singapore to join NTU as an Associate Professor in Computer Engineering.  My wife and daughter had never been to Singapore, other than a brief 2 hour tour we took from Changi airport on a stopover en route to India.  That tour was about the extent of my experience as well, aside from a brief campus visit for an interview. So it was a hard decision for all of us to make, moving so far away to a country we knew so little about.

I am now writing on our third full day in Singapore.  Today was spent setting up our new apartment in faculty housing on campus.   We went to Ikea, and purchased pots, pans, silverware, shower curtains, and other odds and ends needed to start living again.  Ikea in Spore looks just like Ikea anywhere, except that the restaurant has lotus leaf rice and oyster mushroom chicken on the menu to supplement the usual Swedish meatballs.

I also went to a local electronics retailer and purchased a 802.11n/g/b wireless router, with which I am writing this post. My apartment has a 100 Mbit Ethernet port, connected to the university network.  An internet speed test claims I am getting 15 Mbits download speed through the wireless router, which is hard to believe given that I only have 802.11b built into my laptop.  I installed a 802.11n USB external antenna.  The speed test still claims the download speed is 15Mbits, but Windows tells me that the bandwidth between my laptop and the router is 65 Mbits.  It’s hard to tell which is correct, but the external antenna certainly has improved the sensitivity of the laptop, and the web pages load very quickly.

Yesterday we went to Jurong Point, a large 4 story mall about 15 minutes from campus.  The foodcourt in the mall was a revelation.   There were nearly 20 vendors, each offering at least dozen items to choose from.    One cannot order food quickly in Spore: there are so many interesting options to choose from!

The NTU campus is still mostly empty.  Students come back next week for convocation, and classes start on August 4th.  I’m told there are 28,000 students, with nearly 6000 graduating each year.   But now just a few postgraduate students wander around the huge grounds (>500 hectares) along with staff.  I am enjoying the peace and quiet for now.

One gallon toilet

Tuesday, July 8th, 2008

I have three toilets in my house, and each uses 3.5 gallons per flush.  Despite all that water, I even need to flush twice sometimes.   I don’t know when these toilets were made.  You can’t buy toilets that use more than 1.6 gallons/flush today.

I recently bought a Mansfield Quantum One toilet from Home Depot.   It uses only 1.o gallon/flush.   The flush uses a combination of suction pressure and water push to remove waste, in a milder way than airplane toilets.    The noise is startling if you are used to a normal gravity flush. The flush mostly works, but ocassionally I still have to flush twice.  However, it refills quickly.

The Quantum One is considered a high effficiency toilet, which makes me eligible for the rebate offered by the Santa Clara Valley water district.
