How do we translate the sign? Light on is a one and light off is a zero. There is an old joke that says: " There are only 10 types of people in the world: those who understand binary and those who do not." In any case, it does not hurt to at least look at binary once in a while. Ascii (American standard code for information interchange) is usually eight binary characters of ones or zeroes. So you can take the first 8 ones and zeros for the first character. Then to further split out the whole code sequence:  01000001 01010010 01010000 01000001 01001110 01000101 01010100 Then you can convert on character at a time.  You can just look at a table or write a program to do it. Datafile af:  01000001 01010010 01010000 01000001 01001110 01000101 01010100 $ ./b2a1.sh af ARPANET [code]  #!/bin/bash chrbin() {         echo $(printf \\$(echo "ibase=2; obase=8; $1" | bc)) } ordbin() {   a=$(printf '%...

There are several types of games, but lately adventure games seem to be coming back. The original adventures just required a keyboard. No fancy joysticks and or sound cards to deal with.  What is really nice about them is that you can use the same source code more or less on a variety of systems. Sometimes that is known as code portability.  People even want to put it on the Arduino (a micro-controller).  If you do not have an Arduino, you can still play the original game on your desktop system. You might even be able to put it on your router and play it remotely.  You could even put it on a server to play while waiting for some event. Definitely for older or lower resource systems.  Wumpus is probably one of the most popular of the original adventure games. Supposedly it was written in BASIC (Beginners all purpose instruction code) and then translated or ported to "C".   In fact some of the versions of the code,have the original BASIC code embe...

Interesting if you think about it in that offices started out with typewriters, accounting worksheets with a calculator nearby, and file cabinets. We still have the same equipment, but they have evolved a bit. First the typewriter became a command line editor, file cabinet became the database, and the spreadsheet/calculator combination became the early spreadsheet. You had to do a lot of typing to do everything you wanted to do from a command line interface. The eventually the mouse was invented and the graphical use interface was created to take advantage of it. Yet we are still doing the same old thing, but just in a different way. Another comparison could me made that hand painted billboards, mass mailings, and hand made newspapers went to desktop publishing and then were replaced by web pages. Anyway you get the idea…….
