Thanks. It was off-the-cuff and then seemed actually meaningful. ;)

For real? Nice synchrocoinkydink.;)Quote:

Okay then. :p In decimal notation, there are ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. In binary notation, there are only two usable digits: 0 and 1. So if you want to transpose a decimal number to a binary number, then you get something like this table below. ;)

This of course means that you need much longer numbers to write a decimal value in binary notation. However, the 0 and 1 in the binary system correspond to the state of the electrical switches in transistors — such as found in computer chips — whereby 0 stands for an electrical "off" state and 1 stands for an electrical "on" state. And this is how computers work. Everything is literally processed and stored by way of binary values — even alphanumeric characters, inflections and punctuation, because each alphanumeric character, each inflection character, each punctuation mark, et al, is represented by a number in a character encoding table.
Many different such character encodings exist, but the one currently most applicable for international communications is Unicode, of which the UTF-8 subset is the most commonly used one in western languages. Sadly enough, many US Americans still haven't discovered that there is intelligent life outside of the borders of the USA, and so many websites and many software packages still make use of the older ISO-8859-1 character encoding, which focuses mainly on the Latin alphabet and doesn't even contain the Euro symbol (€). Unicode on the other hand even supports bidirectional script, so that languages such as Hebrew, Arabic, Chinese and Japanese can all be properly displayed. ;)
Now, even though humans prefer decimal notation and computers exclusively operate by way of binary values, computer programmers are generally quite familiar with the hexadecimal system, which consists of sixteen digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. If we transpose that to decimal values, then it'll look like in the table below. ;)

So you see, with hexadecimal notation, it suddenly becomes possible to write down much bigger values with far fewer digits. And when it comes to dealing with computer values — e.g. color values, memory addresses or even character encodings — this is no luxury. Of course, underneath, the computer still processes everything in binary, but the hexadecimal values can be translated into binary values by the software in the exact same way as that the software accepts decimal values as input from the operator and gives him/her decimal values as output if so desired — e.g. on a pocket calculator or a digital watch. ;)
Anyway, I guess this is pretty much a digression, so let's return...
:back to topic:
Unicode and Hexadecimal. Cool. :cool::cool: I'll learn to use these in a sentence and impress my computer geek friends. One has been using linux for years, the other is the one always retreating to the game defense.
Excellent. :thup:
Well, all you really had to say was: in binary, 10 = 2 in decimal.
But, all in all a nice write up on hex. Oh, you could have gone into binary, base 4, base 8, base 16 (hexadecimal) and how to convert between each.
...yeah, I’m the guy who built base 8, base 12, and base 16 sliderules when I was a kid.
Here's a challenge for all of you:
BLOXORZ is a FUN addictive game. It has 33 stages and a publicized computer optimized solution. My daughter when in middle school introduced me to it and I couldn't stop playing it. I was determined to equal the best score possible (according to the computer solution) and after months of trying, finally beat the computer score by 1 move. Hah! Now you try it... :)
It's a simplified analog to the 4-color theorem and the other one which I can't remember but it's a mathematical theorem that demonstrates a graph theoretical closed system connected by paths to the vertices within the graph. I provided a graphical solution to that problem to the consternation of all my fellow students not to mention my psychopathic Professor. He actually stated that it was the kind of problem that could be solved without knowing anything. Yeah, he said that. I sat next to a full scholarship student (I was a drop-in) and he spent several weeks trying to solve the problem and couldn't...heh, heh, he eventually asked me for my solution and thereafter if he was having problems on tests would try to cheat off mine. Which I studiously ignored... :)
Have a look at the 137 references with this article if you desire, feel.
like this one , As it has been pointed out on the web, Donald John Trump K107 was 70 years 7 month and 7 days old on inauguration day – K137 Red Resonant Earth.
