Which one is larger?

Between these two numbers, which one is larger? $0.99999\ldots$ or $1$ ?
At a quick glance, most people will say that $1$ is larger than $0.99999\ldots$

However, consider the following:
Let,
$x=0.99999\ldots$

Now,
$10x = 9.99999\ldots$
$10x = 9 + x$

By a simple algebra, we can find that
$x = 1$

It means that $x=0.99999\ldots=1$

Can anyone explain this? Does $0.99999\ldots$ really equal to $1$ ?

1=2?

I just found this old-time mathematical riddle again in some forum.

$x^2 - x^2 = x^2 - x^2$
$x(x-x) = (x+x) (x-x)$
$x = x+x$
$1x = 2x$
$1 = 2$

One is equal to two?! That's totally absurd.
Can you can spot the mistakes?

Why do Japanese eat katsu-don before a match?

Katsu (カツ), is a famous Japanese dish which generally refers to any kind of a deep-fried meat. Even though it is commonly understood as a tonkatsu (豚カツ, pork cutlet), sometimes it can also be understood as a torikatsu (鳥カツ, chicken cutlet).

The word 'katsu' itself can also be written in a different way as 勝つ, which is read in exactly the same say (a homophone).
Katsu (勝つ) means "to win" or "to gain victory". (e.g. 試合に勝つ!, shiai ni katsu! = I'll win the game!)

This is why Japanese sportsmen eat katsu-don (カツ丼 = a rice bowl topped with deep-fried meat) the day before a big match. Japanese students do the same too before taking big tests or school entrance examinations.

So,, it is OK to say:

A katsu-don (カツ丼 = rice bowl with cutlet) is
a katsu-don (勝つ丼 = winning rice bowl).

Do you know that the famous finger-snack Kit-Kat, is called "kitto-katsu (キットカツ)" in Japanese?
Kitto-Katsu, can also be written as きっと勝つ, which means "definitely win!"

World’s Largest Aircraft Graveyard

Ever wonder what happen to aircrafts after they are retired? Aircrafts that are not fly-worthy anymore, will be stored somewhere in an aircraft bone-yard before being turned into scrap metal. These bone-yards are often referred as graveyard for aircrafts.

Bill Gates’ Vision on Zero CO2 Emission by 2050

This is an interesting talk by Bill Gates about his vision to reduce the amount of $CO_2$ emissions in order to stop the Earth rising temperature.

$CO_2 = People \times \frac{Services}{Person} \times \frac{Energy}{Service} \times \frac{CO_2}{Energy}$

How to download MMS streaming video

MMS (Microsoft Media Server) is Microsoft's streaming protocol used to transfer data in Windows Media Services. Since this streaming data is meant to be played in client-side streaming application, it is not an obvious thing to do if we intend to download/save the streaming video to our local drive.

SharePoint Web Part Custom Properties

In my current project, I am creating a SharePoint web part that simply renders a custom .NET User Control from a certain location. I want the user to be able to configure the User Control's properties through the Web Part properties. Therefore I followed the MSDN instruction on how to create a web part with custom properties. However, somehow the custom properties just doesn't show up.

So, after scratching my head for a couple of hours (not literally), I found something that, I think, was not accurately specified:

Personalizable attribute needs to be specified
Use WebBrowsable instead of Browsable attribute

This is the code-snippet that works for me:

[Category("Custom Properties")]
[DefaultValue(true)]
[Personalizable(PersonalizationScope.Shared)]
[WebPartStorage(Storage.Shared)]
[FriendlyNameAttribute("Include lists")]
[WebBrowsable(true)]
[XmlElement(ElementName = "IncludeLists")]
public bool IncludeLists { get; set; }

Hello World!

Yeah.. Hello World! Again.. I must say. There were multiple attempts of creating a blog in the past, be it personal or technical blog.. But all ended up neglected. So, I came to a conclusion that I don't write, and I don't blog. That was just NOT me.

So now why bother trying to do it again?

I lost touch with my friends' life. Meaning that I don't know what they are doing, what they feel, what they think, what they are up to, etc.
OK.. Blame it to my ignorance, because I hardly bother to make the efforts, and because I tend to keep things to myself.. I seldom share what excites me, what triggers my curiosity, or what pisses me off.. So, take this as my effort to make myself available.
A new decade has just begun.
So where the heck had the past decade just gone to?? Human forgets. Especially me. So, I need something to help me remember, means to know where have I been, what have I done, etc.

And here it goes.. Another "Hello World" from the same me..

Cheers!
