Some facts on IPv6

Since IPv6 addresses are 128 bits long, the theoretical address space if all addresses were used is 2128 addresses. This number, when expanded out, is 340,282,366,920,938,463,463,374,607,431,768,211,456, which is normally expressed in scientific notation as about 3.4*1038 addresses. That's about 340 trillion, trillion, trillion addresses.

It's enough addresses for many trillions of addresses to be assigned to every human being on the planet.

The earth is about 4.5 billion years old. If we had been assigning IPv6 addresses at a rate of 1 billion per second since the earth was formed, we would have by now used up less than one trillionth of the address space.

The earth's surface area is about 510 trillion square meters. If a typical computer has a footprint of about a tenth of a square meter, we would have to stack computers 10 billion high blanketing the entire surface of the earth to use up that same trillionth of the address space.
Looks like this figure is almost infinite.

My opinion on PRUinvestor guaranteed plus product

I got to know of Prudential's new product PRUinvestor guaranteed plus only recently.

From agents, it is said to be 1) 100% Capital Guaranteed at maturity, 2) 2.5% p.a. interest guaranteed (Total 13.14%), 3) able to accept both cash and SRS, 4) and telling people application date for such "cool" product is ending soon but that's not really the case. I do not like the way products are marketed by agents.

1. 100% Capital Guaranteed at maturity

It is not really 100% guaranteed if it is guaranteed upon 36 months.

2. Sometimes marketed as 13.14%

This is a common tactic to "fool" aunties and uncles who are unaware of the compounding effect.

3. Able to accept SRS

At the rate of 2.5% p.a., I would say investing SRS monies in such product does not make sense to me since the new CPF interest rate structure is close to 2.5% p.a. too. At least CPF is truly 100% capital guaranteed.

4. Publish application date to be earlier than actual

This tactic attempts to make consumers make r…

How to stop FortiClient from starting automatically?

Installed FortiClient recently but the challenge in disabling the application/service from running automatically on every start-up annoyed me. Attempt to stop 'FortiClient Service Scheduler' only return 'Parameter is incorrect' error message.

An article on Technet help solve my trouble. To stop FortiClient from starting automatically, try the following:
Shut down FortiClient from the system tray.
Run net stop fortishield on command prompt.
Run msconfig.
On msconfig, switch to the Services tab. Clear the FortiClient Service Scheduler check box and click Apply.Run services.msc on command prompt to open up show all available services.Look for FortiClient Service Scheduler. Switch Startup type to Manual.Restart your computer. FortiClient should not be running automatically the next time round. Hope it helps.
