    Dijkstra didn't have to debug an option valuation model written in C++ by a math PhD... True story... Almost every variable in the Black-Scholes calculation was one or two letters long, and none of them had any relevance to what they represented. Don't get me wrong... It (mostly) worked, and it was fast, but... Ow, my eyes!

    When Black and Scholes were figuring out how to value options, though, they probably were using one- and two-letter variable names, and they ended up winning the Nobel Prize. Maybe the difference is that people don't have to "maintain" mathematics. There was a movie where Leo DiCaprio (or maybe Matt Damon?) was a maintenance man who did mathematics... but that's a different story. :-D

      I believe you are refering to Good Will Hunting[^] and it stared Matt Damon.

      Computers have been intelligent for a long time now. It just so happens that the program writers are about as effective as a room full of monkeys trying to crank out a copy of Hamlet.

        I always found naming the program itself hardest. Which is why most of my project names are fairly meaningless...

              I don't use anything under 80 characters in length. I try to name it and describe it all in one name. I also have a tendency to give it a feminine or masculine slant depending on what kind of work these objects are doing...names usually ending in either "ita" or "ito".

                I solve this by using a single Object variable called theKey across my entire project. I assign all local references to this variable and cast to the required derived type before calling a method or property. On occasions I may need two or even three such variables (I suffix 1,2,3 to get theKey1 and so on). Problem solved. :-\

                  I prefer to call all my variables a1, a2, a3, a4, and so on. Also, once I get to a6, I use another letter (say, b1)... that way, I only ever have to use my left hand and can keep my right hand on the mouse. It's a very efficient technique I wish everybody else would adopt. Until then, I just refactor all the code I see with overly long variable names like "count" (that's a particularly bad name because some of the characters require the right hand to type). I sleep easily at night, comfortable in the knowledge that all my refactoring has made the world a better place. :-\

                  This is a particularly stupid tip and would never work. Apart from the fact that it would require superhuman mental gymnastics, once you have more than 42 variables, in order to maintain alphabetic ordering, it is yet another invidious ploy by the militant fundamentalist wing of the ASL (Anti-Southpaw League). Please remember that The Lounge is no place for these religious outpourings.

                      That's the one! Ironically, I was too busy with mathematics classes to see that one when it came out.

                          You could use an array or a list to make the solution more flexible. Then you have theKey[0], theKey[1], ...

                            I would also allocate it right away with 640,000 elements (that ought to be enough for anybody).

                                I just went for item. And yes, it is to remain abstract. It is an Interface Method that has a T (as in generic) as a parameter. That is the reason I did not want to go for obj. Because the parameter is of type T, which is more specific than an Object.

                                It's an OO world.

                                void DoSomethingGeneric(T t){ ... } If it's just any T, with no further restrictions, the fact it is a 'T' is the only thing that identifies it, so I'd call it 't'. The fact that it's a T that something is done with should be clear from the method name.

                                  I agree. Since all the syntactic characters are on the other side of the keyboard (parens, braces, semicolon, equals and single quote; double quote too for Americans), clearly variable names ought to use exclusively the right side of the keyboard (p0, p9, p8, ... p5, o0, ... etc).

                                    it's easy when you coding some useless crap, real programming never was easy and will never be :~

                                    d{^__^}b - it's time to fly

                                      It's called irony :)

                                        When Black and Scholes were figuring out how to value options, though, they probably were using one- and two-letter variable names, and they ended up winning the Nobel Prize. Maybe the difference is that people don't have to "maintain" mathematics. There was a movie where Leo DiCaprio (or maybe Matt Damon?) was a maintenance man who did mathematics... but that's a different story. :-D

                                        I always get those two mixed up, made watching The Departed very difficult to begin with :)

                                          Dijkstra didn't have to debug an option valuation model written in C++ by a math PhD... True story... Almost every variable in the Black-Scholes calculation was one or two letters long, and none of them had any relevance to what they represented. Don't get me wrong... It (mostly) worked, and it was fast, but... Ow, my eyes!

                                          I know what you mean - my colleague (who writes the B-S module for his option pricing program (which I maintain)) loves names like henry, peter, peterp, peter2 etc - I'm just glad I don't have to work on that bit of code. I used to employ a programmer who was very good, and very hard working, but he never used any kind of meaningful names for anything, so a complex C function representing, say, a vector drawing interpreter, would contain tens of variables named a,aa,aaa,aaa, x,xx,xxx,xxxx, i,ii,iii,iiii,iiiii and so forth... 8)
