MRC Button On Calculator

By Jim Sheng
Casio Calculator
Do you know all buttons on a calculator? I have a Casio calculator, it has MRC, M+, M-, and right arrow, Euro/local and Euro Rate set button, it took me quite long time to figure them out.

I need to keep a track for delivery orders, because our mean boss always guards his sale number as national top secret. At first I wrote them down on a piece of paper, but that's not the way for highly intelligent person such as me to steal business secret. So when I found out the memory function button on my calculator, I was very excited about it (Please don't laugh at me.). So the MRC is short for Memory ReCall, M+ is for adding to the memory, and M- is for taking away from it.

Sometimes I have to leave my calculation half way to deal with something else, I just press the M+ button, to save the sub total to memory, and come back to it later.

Press MRC twice to clear the memory, press once to recall the memory.

Sometimes you input a number, or even add up a lot numbers already, but you forget press the plus button, a disaster indeed, because you press a big number with decimal point after the sub total so far , but you can't remember what it is. Now you press the RIGHT ARROW button, to go back. For example, you input 31.56, press four times to cancel it.

Your calculator may haven't a Euro conversion button, I have also token long time to find out how to set the rate, which is press and HOLD the rate set button for couple of seconds (I don't know how many second.), then input a number and press the Rate Set button again.

It seems a tradition to design the key to function like this, such as power button on a computer to force shut down, on Amazon Kindle you hold power slide for 20 seconds, and press the Home button for 1 minutes, then you have an option to reset your kindle.

Of course if you bought the calculator yourself and still keep the instruction, you can always read it whenever you're puzzled by these buttons, but I don't think many people have the habit of keeping user manuals or instruction.

coat-of-arms

By Jim Sheng
Heraldry probably began with the knights in armour. When wearing a helmet in battle or in tournaments a knight could not be recognised; so he used symbols to decorate his shield and surcoat. The surcoat was the loose garment worn over the armour to protect it from rain or hot sun and actually was the "coat-of-arms"; it was decorated on the front and back with the same device as on the shield. The correct expression for entire design is an achievement . An achievement consists of the shield, helmet, rest, wreath, mantling and motto. These are the main parts. To them can be added supporters and a compartment. In the centre is the most important part, the shield . The surface of the shield is called the field  and on it the colourful charges are placed. The shield is called the arms or coat-of-arms  and can be drawn in any shape - in an upright position or slanting, which is the position it would fall into if hung on a peg. In Heraldry it slants to dexter. The helmet denot...

You can find your Wireless Network Key on Virgin Media Wireless Router

By Jim Sheng
We have a new netbook computer, and don't know where to find network key, which is needed to setup wireless connection. A network key may also be called WEP (Wired Equivalent Privacy) key or WPA (Wi-Fi Protected Access) key. A wireless network key is a security feature that prevents unauthorized users from accessing a wireless network. An unprotected network is an unlocked virtual door, anybody within range can piggyback on the network undetected. I use Virgin media broadband with a Virgin media wireless router, this router has a WPA key taped on the router, that WPA key is an English word consisting of 10 letters. To tape network key on the router is a good idea, because we may never lose or forget a wireless network key as long as we possess the router.
