Living: Sliding wardrobe door opens by itself [SOLVED]

Sliding wardrobe door opens by itself [SOLVED]
Image from Locky's English Playground
Back in January, my sliding wardrobe door had been refusing to close, opening by itself automatically. Tried climbing up to the top of the wardrobe and lying flat on the floor looking up to see if there were any broken parts, but still failed to see anything wrong with it. What I am certain of, is that there is no ghost doing this. It has to do with science.

Looking up, door is slightly tilted downwards on the right side

Took me a while to figure out what the issue really was. Apparently, it has to do with the weight of the sliding door (and gravity, if you like). 

Looking from the top, door is slightly tilted downwards on the right side.

Because the sliding wardrobe doors are made of heavy wood, the weight it exerts on the nuts and bolts is immense! Repeated use of the doors from pulling the door handle from left to right adds extra force to the nuts and bolts, causing the door to dip to the right side over time.

This dip plus the weight of the door create a side-way force from left to right, making the door sliding open on its own. After tightening the nut from above the door, the problem was finally solved.

Now, at this point, I am thinking, why has no one ever linked the learning of free body diagram in Mathematics or Physics to realistic cases like this? This will give meanings to students as to why they have to learn resolving forces?

Techonology: Samsung Galaxy Note 4 emmc failed, no pit, DIY fix [SOLVED]

Note 4 Europe version
Image from Locky's English Playground
My mum left me this Note 4 Europe version a year ago and it just kept refusing to be switched on. Sometimes it flashed the logo for a split second, sometimes it just froze on the boot screen, most of the time, nothing happened.

So I searched the internet, and found the craziest advice which I tried because there was nothing more to lose. It was the advice of freezing the phone in the freezer with a plastic bag over it. Hyperskeptical I was, I froze the phone in a Ziplock bag for 10 minutes and tried switching it on. It worked!!!! It booted up once smoothly into its usable state for like a minute before it crashes again. So I redid the process, this time, it booted up till it hit some EMMC error that I can't recall any more and stopped. I then tried to freeze the battery and phone separately, as well as freezing just one of them. The battery-only freeze didn't work, the phone-only freeze got me as far as the EMMC error and it could never boot to any usable state again.

Desperate for more fail-worthy attempts (Wow! Can't believe I just thought of this word. Really like it. I am not the creator of this word though.), I found the following YouTube video and followed it, and WOW! I fixed my phone!!! So it was all because that the EMMC was designed and placed so close to the metal frame that somehow the electrical signals got disrupted, placing thin pieces of cardboard paper did the magic trick and the phone is resurrected! I gave the phone to my elder daughter and she is having fun with it! So if you have similar problem with your Note 4, this is the ultimate video guide.

Huge thanks to the creator of this video!



As to why the freezer method works, I am not quite sure, but I guess maybe freezing the phone's EMMC  long enough shrinks the chip just enough to separate itself from the metal frame temporarily. When the chip starts to expand again, the phone returns to its inoperable state.

All I know for sure is, I can put one more skill on my CV. What should I call this skill? Any suggestions?

Auto & Environment: EV Numbers and Growth In Hong Kong As Of Oct 2018


New Tesla EV price after reduction
Image from Tesla HK

I haven't published any EV numbers and growth in Hong Kong since the figures of Aug 2016 was released. The fact is, there is nothing to report, and we all know the situation of EV is bleak. Ever since Financial Secretary Paul Chan mo-po's removal of EV FRT waiver, EV sales in Hong Kong have not recovered to the slightest. Even after the “One-for-One Replacement” Scheme was launched on 28 February 2018, buyers' confidence remains low. How low?
Data from Transport Department Hong Kong
Image from Locky's English Playground
Ever since that final wave of EV sales back in March 2017, over a period of 19 months till October 2018, only a total of 351 private EVs have been registered, compared to 35,483 ICEVs added in the same period, which is approximately 1 EV in every 101 ICEVs sold. (In another comparison, 351 private EVs is about two times of units sold in Tesla HK's worst months.)
Data from Transport Department Hong Kong
Image from Locky's English Playground
Still, there is no way that the Hong Kong government will admit their fault for driving EV growth to an early grave. They didn't admit when EV taxis didn't work, not even till the last one ended up on scrap heap. In a city that considers electric scooters as 'a car' but has no driving licence to apply for, there is little reason for the EV-hopeful to remain...well... hopeful. They know the government officials' rhetoric too well, and no longer want to argue with the wall of deaf ears.

Maybe this is why Tesla decided to take matters into their own hands and reduce the price of Model S and X by 8-20% starting from today Will this help? I do hope so, but 8-20% reduction (tax reduction included) is still far from the cost saving compared to the good old days when EV FRT waiver was still waving and smiling. Tesla Model S and X 75D is still over a million Hong Kong dollars with tax. This means the used inventory is still the most attractive and will remain so until the US$35,000 Tesla Model 3 arrives.

As for our EV enthusiast friends of Singapore, you are not alone.

Vocabulary: Supercalifragilisticexpialidocious IS NOT Meaningless

Image from RTHK


Came across a page on RTHK called 楊官教英文 ----- 楊官信箱 and I was randomly reading the mailbox questions and answer. At first I thought it was pretty interesting until I saw one reply, and I thought I have to write something about it. I have captured the question and answer in the image below:

Image from RTHK

Is it a word that really carries "no meaning"?

First, let's familiarise ourselves with this song from the 1964 Disney musical film Mary Poppins.


and the lyrics go,

Supercalifragilisticexpialidocious

It's Supercalifragilisticexpialidocious!
Even though the sound of it
Is something quite atrocious
If you say it loud enough
You'll always sound precocious
Supercalifragilisticexpialidocious!
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
Because I was afraid to speak
When I was just a lad
Me father gave me nose a tweak
And told me I was bad
But then one day I learned a word
That saved me aching nose
The biggest word you ever heard
And this is how it goes
Oh, supercalifragilisticexpialidocious!
Even though the sound of it
Is something quite atrocious
If you say it loud enough
You'll always sound precocious
Supercalifragilisticexpialidocious!
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
He traveled all around the world and everywhere he went
He'd use his word and all would say there goes a clever gent
When dukes and Maharajahs pass the time of day with me
I say my special word and then they ask me out to tea
Supercalifragilisticexpialidocious!
Even though the sound of it
Is something quite atrocious
If you say it loud enough
You'll always sound precocious
Supercalifragilisticexpialidocious!
Um-dittle-ittl-um-dittle-I
Um-dittle-ittl-um-dittle-I
So when the cat has got your tongue
There's no need for dismay
Just summon up this word
And then you've got a lot to say
But better use it carefully
Or it can change your life
For example
Yes?
One night I said it to me girl and now me girls my wife
Oh! And a lovely thing she is too. he he he
She's Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
Supercalifragilisticexpialidocious!
by Richard Sherman / Robert Sherman

From the song, we can tell that this exceptionally lengthy word definitely carries a meaning, and it is definitely a pattern-reforming creativity (Carter, 2004) of neologism which comes from a combination of multiple words (Law, in press).

Image from OED


While the Oxford Online Dictionary has the answer, meaning extraordinarily good; wonderful, and mentioning that the word first appeared in the 1940s, that is 24 years prior to the release of the song and film, it still does not say what the neologism is comprised of.

Turns out, Wikipedia has the answer. The page cited Lederer (1998)'s analysis of the word,

An analysis of the individual word elements produces another definition. Richard Lederer, in his book Crazy English, defines the word roots as follows: super- "above", cali- "beauty", fragilistic- "delicate", expiali- "to atone", and -docious "educable", which, he writes, produces an overall meaning of "atoning for extreme and delicate beauty [while being] highly educable"

And there we have it! Clear as day! "Atoning for extreme and delicate beauty [while being] highly educable". Supercalifragilisticexpialidocious IS NOT Meaningless!
