Police Warning - LIPSTICK MARKS ON FRONT OR REAR WINDSCREEN OF CAR

2011-02-26T16:06:00.000+08:00

Don't know whether true or not but just be careful if you happen to see such thing on your car.

Warning..!!!! Warning..!!!!

Just last weekend on Friday night we parked in a public parking area. As we drove away, I noticed a lipstick mark in the shape of a woman's lips on the front window of the car. We thought it was a joke and just laughed at it. When I tried to wash it off, the marks didn't come easily as it was waterproof. Luckily my friends told me to get back into the car as it could be someone waiting for me to get out of the car. The very next day, I parked my car at the same parking area and when we returned after our shopping, my car was missing. I had to make a police report the stolen car and forward an insurance claim .

Then we received this email yesterday:
WARNING FROM POLICE :
THIS APPLIES TO BOTH WOMEN AND MEN
BEWARE OF LIPSTICK PRINTS ON THE FRONT OR BACK WINDOW OF YOUR VEHICLE. THIS IS NEW WAY TO DO CARJACKINGS (NOT A JOKE)

Heads up everyone! Please, keep this circulating.....
You walk across the parking lot, unlock your car and get inside. When you get into your car, you notice a lipstick mark on the front or back windscreen. Many drivers do not take this seriously and end up just wiping those lipstick stains off. This is a new syndicate making their rounds in Malaysia. This lipstick stain is a marking for the syndicate members to identify which car to be stolen or car jacked. This new method has been discovered already in Penang, Malacca, KL, and JB.

Be careful if you see the lipstick mark on your windscreen. This means your car has already been marked and could be stolen from under your very eyes , even in the car park. You are advised not to leave your parking ticket in the car in any carpark and if you discover that your car had already been marked by the lipstick stain, please be advised to install a reputable alarm system in your car to deter the thieves.

BEWARE OF THIS NEW SCHEME THAT IS NOW BEING USED...If you see a lipstick stain on your window, don't just ignore it. And be thankful that you read this. I hope you will forward this to friends and family. Please keep this going and tell all your friends.

The Inertia Kiss - I Won't Say Adieu

2010-11-25T10:45:00.000+08:00

I wonder why the hell I stay in this town

Ain't much to do when the sun goes down

I think about what I'll do when I'm with you

Still don't know why you went away

When black and white turns into gray

Life was cold but I was warm when I kissed you

When I'm with you I feel warm inside

When I'm with you time and space divide

When I'm with you I am so alive

When I'm with you

And I don't know how I'm gonna live this way

Eternity burned out that day

And I don't know how I'm gonna spend my life without you

And the church bells are ringing all across the world

And prophecies go unfulfilled

Cause they always told me I would spend my life with you

I won't say adieu

How much more time will I have to wait

You left me in a restless state

I walk around like I'm in a trance till I'm with you

I wonder where on Earth you could have gone

Feel like a siren that somebody left on

Screaming out in the night that I miss you

When I'm with you my heart pounds like rain

When I'm with you I am immune to pain

When I'm with you I feel no restrain

When I'm with you

And I don't know how I'm gonna live this way

Eternity burned out that day

And I don't know how I'm gonna spend my life without you

And the church bells are ringing all across the world

And prophecies go unfulfilled

Cause they always told me I would spend my life with you

I won't say adieu

And I don't know how I'm gonna live this way

Eternity burned out that day

And I don't know how I'm gonna spend my life without you

And the church bells are ringing all across the world

And prophecies go unfulfilled

Cause they always told me I would spend my life with you

I won't say adieu

Adieu

Miranda Cosgrove - Kissing You

2010-11-24T14:29:00.000+08:00

Sparks fly
It's like electricity
I might die
When I forget how to breathe
You get closer and there's
No where in this world I'd rather be
Time stops
Like everything around me
Is frozen
And nothing matters but these
Few moments when you open my mind to things
I've never seen

'Cause when I'm kissing you
My senses come alive
Almost like the puzzle piece
I've been trying to find
Falls right into place
You're all that it takes
My doubts fade away
When I'm kissing you

When I'm kissing you
It all starts making sense
And all the questions
I ve been asking in my head
Like are you the one should I really trust
Crystal clear it becomes
When I'm kissing you

Past loves
They never got very far
Wall's up, made sure
I guarded my heart
And I promise I wouldn't do this till
I knew it was right for me

But no one (no one)
No guy that I met before
Could make me (make me)
Feel so right and secure
And have you noticed
I lose my focus
And the world around me disappears

'Cause when I'm kissing you
My senses come alive
Almost like the puzzle piece
I've been trying to find
Falls right into place
You're all that it takes
My doubts fade away
When I'm kissing you

When I'm kissing you
It all starts making sense
And all the questions
I've been asking in my head
Like are you the one should I really trust
Crystal clear it becomes
When I'm kissing you

I've never felt nothing like this
You're making me open up
No point in even trying to fight this
It kinda feels like it's love

Cause when I'm kissing you
My senses come alive
Almost like the puzzle piece
I've been trying to find
Falls right into place
You're all that it takes
My doubts fade away
When I'm kissing you

When I'm kissing you
It all starts making sense
And all the questions
I've been asking in my head
Like are you the one should I really trust
Crystal clear it becomes
When I'm kissing you

BUDGET 2011

2010-10-16T06:49:00.000+08:00

Our Prime Minister, Datuk Seri Najib Tun Razak tabled a RM212bil budget for 2011 Friday, centred on four key strategies designed to transform Malaysia into a developed and high-income nation by 2020.

He said Budget 2011 would emphasise efforts to "transform the nation into a developed and high-income economy with inclusive and sustainable development, spearheaded by the private sector as well as focus on the well-being of the people".

LOVE IS GREAT???

2010-10-16T05:00:00.003+08:00

Is it true that love is great?

Well..for me the answer is yes!

Why? Because love is a gift from God.

You only could love somebody when God gives

you this.

But remember one thing!

Never ever wasting your love

with somebody that you think you can't love

him/her as he/she loves you.

Well..this is just my opinion.

How about your opinion about love? ^_^

Are You A Facebook Addict?

2010-04-04T13:41:00.003+08:00

My questions for you..

Are your personal relationships taking a backseat to Facebook?

Do you think about Facebook even when you’re offline?

Do you use Facebook to escape problems or homework?

Do you stay on Facebook longer than intended?

Have you ever concealed Facebook use?

If you answered yes to any, you might be a borderline addict – no joke.

Miss Dz admit that she is a facebook addict.

Mwahaha..

But guys...my advice for you and for myself of course,

please decrease your level of facebook addiction.

It's not good for your health.

~LOL~

• flags
• time-to-live
• header checksum

5. Which portion of the network layer address does a router use to forward packets?

16. Which three statements are true about routes and their use? (Choose three.)
If no route to the destination network is found, the packet is returned to the previous router.
If the destination network is directly connected, the router forwards the packet to the destination host.
• If multiple network entries exist for the destination network, the most general route is used to forward the packet.
• If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router.
• If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
• If a host does not have a route manually configured for the destination network, the host will drop the packet.

17. Refer to the exhibit. A network administrator is troubleshooting a connectivity problem and needs to determine the address that is used to forward network packets out the network.
