How to make a 4 digit PIN 24 times secure by adding just one Button

Think man, if Letters( Characters can be Upper case and Lowercase ) , why numbers can't be.

So if we have uppercase and lower case numbers we can have a very much more secure 4 digit pin?

I mean would it be 24 times more stronger?

Hello,

Any body out there, with a mathemetical acumen?

How to create a Fail Proof Robust OS in a Jiffy

Thinking out of the box makes every thing possible.

Take for instance what if the OS is not stored or installed in the Hard Disk but comes as ROM chips the WORM type. ie can't be modified hence can't be corrupted.

If there are hot swappable chip slots then redundancy and multi boot OS can be created in a jiffy by just slipping in the chips to the slot. No chance of corrupting of OS.

Also just change from which slot you want to boot at the time of booting or shutting down and hey you have a multi boot PC.

To build redundancy in the PC put two chips of the same Os in the stwo slots and hey if one chip fails the other takes over, I mean high avialability in the data center would never be a problem again.

How to create Robust OS which use less Memory :

Why not design modular OS. OS divided into logical groups depending on the use of the functionality.

This way only modules required for a particular function may be loaded in the memory hense giving less latency and more responsive programs in a cheaper computer and also reduce the future digital divide and a digital society. This coudl be the economising effect of Modularizing OS.

Also a high end use could be co-Operating Systems, which work with Each other.

For example you want to think of a computer system of the Future. One which would go to chat mode and only talk to you and play your fav music, so for that just AudioOS may be enough ie diaplay may not be on.

Suppose you want to get a AI Expert Problem solved the Modular or co - OS may be loaded to memory which could diagnose your problem.



A Picture OS for Defence USE

You could create a PIC component to encode and encrypt your message where a particular picture means something, and a series of pictures could mean some thing. Highly secret information could be sent as a image or a fish school of images, which know how to combine and give the message, only on your processor.

Come on beat that.

Now do that development and sent me the 100 dollar cheque.
