Luckily, the LG UltraWide did not have Backlight Bleeding

A biggest fear of buying a new, expensive monitor is backlight bleeding. The way LCD monitors work is that the monitor screen is lighted from the back. There is a panel in front of the backlight that blocks the emitted light, thus creating different colour per pixel. A complete blockage produces the black colour. Normally, around the bezel, the panel have issue blocking the light. This is due to the pressure from the bezel itself or pressure created when you are pressing the screen too hard when moving the monitor. This causes the panel to fail to block the light completely and thus, it bleeds around the panel.

Fortunately, this LG 38” have good manufacturing process or a very good QC. 4 days after using it, I decided to test it for backlight bleed.

1/ Testing is a simple procedure of loading up a full screen black wallpaper.. or you can just go to this website and click a link to load up a black screen. 

2/ switch off your room light so tbe room is in darkness. This is so its easier for you to spot any inconsistency in the screen. 

3/ The result? Judge for yourself (the middle white dot are actually the mouse cursor):

I set the monitor brightness to 40, which is what I am using most of the time (for reading)

Surprisingly, though, the MacBook Pro 2017 from work, with a Retina display, demonstrate some degree of backlight bleed. See top left, bottom left and top right? There are traces of light that seems to bleed out of the corner, an indication that the front panel failed to block the white light completely. Hmmmm....

Setting Brightness to maximum.. and still looks ok! Phew!

I am pretty relieved that my monitor is free from backlight bleed... so far. I need to handle the screen tenderly. No pressure especially when moving the screen!

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.

Amazon Alexa in Malaysia - does it work well? A review...

Back in July, Amazon Australia had a Prime Day. I joined the trial using my usual Amazon account and ordered an Echo Dot, Echo Plus (the taller one with a built-in hub) and a Kindle Paperwhite, shipping them to a dear friend in Australia.

My friend visited Malaysia and brought the Echos with him two weeks ago. You can imagine my thrill to get my hands on Alexa and start using it... in Malaysia.

As a side story, sometimes, you can't believe how events are aligned properly to prepare my place to be a connected home - I bought a superb new mesh network router, eero (by the way, I'd say it's one of my best electronic purchases after an iPhone! It is that good), which acts as a strong WiFi backbone as it blanket my double storey house with a reliable and fast WiFi. Then, maxis launched Fibernation program which let me to upgrade my internet from 6 Mbps (pathetic) to 100 Mbps with just an additional RM10/month! Now, my super reliable router is connected to fast, fast internet! …

Why did we choose Sekolah Kebangsaan Taman Megah?

Which school did we transfer Jane to, that's probably what is in your mind? The graphics and the title above would have informed you the name of this school. But why this school?

We first heard of Sekolah Kebangsaan Taman Megah from a friend. Her 8 and 11 year old daughters are now studying there. Typically, she doesn't really talk much about the school but when probed further, she told us all about the school. There are few things she said which struck me really hard. The first being that the kids and the staff in the school are a happy lot. Yes, even the staff. She said when you go to the school and talked to the teachers, the Headmistress Puan Khoo or even the office staff, you will feel an ambiance of  warmth and politeness from everyone. It's a very pleasant feeling, unlike many schools where the atmosphere is cold. And she also said that the children there, her own two daughters, are always looking forward to school.

The second thing she said which also left an impr…
