Variables in programming are similar to variables you might have seen in math class, with the difference being that a variable in programming can represent more than just a number. The best thing about a Boolean is even if you are wrong, you are only off by a bit.ДЄ Boolean is a data type which can only have one of two possible values: true and false.ДЄ data type just means what type of data is held within something like a variable. Since there is always one more bug, the joke says only the third, non-existent method is the only way to write an error-free program. It is possible to write a program that seems to have no errors, usually referred to as вЂњbugsвЂќ in programmer lingo, but Lubarsky's Law of Cybernetic Entomology states вЂњThere is always one more bug.вЂќ The bug may be so tiny and under such specific conditions that youвЂ™ll never see itвЂ¦ but there is always one more bug. This joke refers to the fact that it is actually impossible to write an error-free program. There are two ways to write error-free programs only the third one works. It uses the letters A, B, C, D, E, and F as the вЂњdigitsвЂќ above 9. In addition to decimal (base-10), octal (base-8) and binary (base-2), hexadecimal (base-16) is also used commonly in programming. If you donвЂ™t understand binary though, youвЂ™d think there are ten types of people, which would be weird. Those who understand binary and those who donвЂ™t.вЂќ So, the joke means вЂњThere are two types of people. If we convert binary 10 to decimal, we get: 1 * 2 1 + 0 * 2 0 = 1 * 2 + 0 = 2. Since it is a base-2 system, it has only 2 digits, 0 and 1. This is a binary joke binary beingВ a base-2 system. Those who understand binary and those who donвЂ™t. There are 10 types of people in this world. When you get to a number higher than 7, you also add another column, so you count like 6, 7, 10, 11, 12, and so on.Дў. A base-8 system means it has 8 digits (0, 1, 2, 3, 4, 5, 6, and 7). Octal (from the Latin root oct- meaning eight) is a base-8 number system commonly used in programming.

When you get to a number that is higher than the highest digit, you add another column to the left, so you count like 8, 9, 10, 11, 12, and so on. That means a base-10 number system 10 digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) and is where it gets its name from (decimal, from Latin decimus, means tenth). A number system has as many digits as its base number. The joke here is that Octal 31 (which abbreviated looks like October 31 st, Halloween) is equal to Decimal 25 (which abbreviated looks like December 25 th, Christmas).Дecimal and octal are two number systems with different bases.Дecimal is the base-10 number system that everyone is familiar with. Why do programmers always mix up Halloween and Christmas? Because Oct 31 = Dec 25. (UPDATE, binary jokes are now my favorite.) 1. He was kind enough to explain the punchlines of the following programmer jokes, for those of us who are dazed and confused. Not a programmer? Thanks to our very own Development Manager, Christian, you can be in on the jokes, too. Ahhhh.programmer humor! Hilarious to coders and completely baffling to the rest of us.
