I don't know if this is even worth blogging but I thought I should at least find out if it is really common to Americans or that it is just unique to my kwai poh guest. My guest is an American from Dallas, Texas. Today, she told me that it is a pretty common practice to have the a/c (air conditioner) switched on 24 hours a day. When nobody's home, for example, during the day time, the temperature of the a/c is set to a higher level so that it does not need to cool the place too much - yet the fact is that the a/c is still switched on and therefore is a waste of precious electricity. And oh, they have centralized a/c-cum-heater in the house, so you can imagine how much of electricity is being wasted even as I am typing now.

You see, in Malaysia, a tropical country where it is generally hot and humid, people don't switch on a/c for 24-hours! We usually switch it on at night when we wanted a more comfortable sleep. In fact, most of us were brought up with the habit of switching off room lights if there's no one in the room. And here, we have Miss American telling me that even when there's no one at home, her centralized a/c is still running, cooling the whole house, not just rooms, albeit at a higher temperature.



  1. I totally agree with you that that is a waste of resource and I strongly against it. The American keep saying that we Asia people did not protect the forest, we pollute the environment etc etc. What about them? How much resource they wasted by turning on the AC 24 hours.

  2. Do we have to guess who is the biggest contributor to the green-house effect?! We all know, but not THEM!

  3. I have nothing against Americans but sometimes their ignorance is really beyond my belief. They are smart people yet they can be so freaking ignorant at times. And rotitelur is right - they like to point their fingers at other people when they are the greatest contributor to green house effect and ozone depletion. Grr...

  4. Dude, I practised our way here - I tak switched on A/C when go to work. At night also - cool here,so I open window ingat fresh air - sometimes betul2 cold enuf. OK, now cuaca getting HOT HOT HOT. This week, whenever I balik apt - I walked into an oven - HOT. Then when I switched on A/C - geee - initially tot their system weird - it just took long long time to cool down the apt (sometimes I nak tidur still HOT). So I went asked around as well, and all my friends said it is cheaper to have the A/C running most of the time - they tested - they said ON and OFF - their compressor no good wor ....hmmm, back home, whenever we want - our split unit A/C works great - sekejap aje sudah SEJUK, kan ....conclusion, I think places in USA which is super duper HOT - it is the practise to have A/C ON - things work differently - I doubt they are wasting energy lah - ...they have their own way of doing it differently :)

One million daimoku

In April 2008, Anne and I started our resolution to chant 1 million daimoku in one year. It's already Jan - and I am only one-third of the way. I really need to WORK HARDER - coz I made another 1 million resolution from Jan - Dec 2009.

The chart you see on the right of this post is a chart that we put beside our butsudan. It tracked our chanting progress. Every 20 minute, we coloured one box. Mine is the one on top, Anne's at the bottom - you can see that she made much better progress than me! Hmmm.. come to think of it, I am not even at one third!!

Edit 22 March 2009: Thanks to Google, a couple of friends in faith found this post and they want to know how many hours of chanting is required to achieve one million diamoku. Here it is. Based on our publication in Malaysia, 20 minutes of chanting is equivalent to 1,000 daimoku. So, one hour is 3,000 daimoku. 1 million would take about 333 hours.

Edit 8 April 2018: Checking my blogger stats, this post is pretty high up in …

LG UltraWide Monitor 38WK95C Review

I bought this today. It was not an impulse buy. I spent months researching and then two months of waiting for stock from LG Malaysia.

Trust me, it is not easy to buy a modern monitor these days.

I have a few criteria:
ultra wide screen regardless of size - can be 32" or 34" or even 34"it must be IPS screen, not TN or whatever the other one is calledit must have USB-C to charge the MacBook Pro and also to extend the display of the MacBookit must have good speakers. Not the puny ones that some Dell monitor shipped with. Really good ones. I hate having to plug in the speaker jack from PC to monitorit should have G-Sync supportbonus - it has nice legs that doesn't take up space I have searched high and low. I looked for Asus, I looked at Dell and Alienware.. none of them ticked these checkboxes, particularly that USB-C one..

I realize that I really wanted the USB-C and good speakers. I don't really care about G-Sync because even though I still play games, I spen…

2017 Honda CRV in Malaysia! An owner's review

After years of driving an old car, I finally decide to change. And having a small family, I was eyeing a SUV. Last year, we were considering a Mazda CX5 because of its exterior look but after inspecting it in a showroom and then sitting on a Honda CRV, we have no doubt that Honda was the choice to go. Our decision was simply based on how spacious the interior cabin of the CRV is compared to the CX5.

And so, we have to decide whether to get one early this year or wait for the new CRV which was supposed to launch in May 2017 (well, that was before Honda Malaysia decided to delay the launch date after Raya). What made me wait for the new model was that the sales agent told me that the new CRV will have a new engine and Apple CarPlay! Being an Apple fan, as you can tell from this blog, I definitely wanted CarPlay. We dropped a deposit with the showroom sales agent in April.

I waited patiently and when Honda finally launched the car on 12 July, the wife and I went to the showroom for a lo…
