Oooh, you can do that?

IList newList = new List(); //I eat serial killers for breakfast newList.Add("word"); //You think you can take me? Think again a*shole

Yeah right like anybody does that LOL I have seen some doozies in my time. My favorite is one-letter variable names! Like
StringArray a = new StringArray();

... in the right circumstances. Pretty much being that the variable is in a very short scope and is basically a tmp variable, where the name is not important.
Don't let my name fool you. That's my job.
That point is irrelevant. I am talking about seeing this in high performance scientfic codes where a single function can be thousands of lines long. Makes the code fairly hard to understand if all the tmp variables happen to be one letter, trust me.

I just settle for calling them tmpStr tmpInt etc so I know. Tend not to use them at all unless I have to

That point is irrelevant. Typical phud, discrediting anything that disagrees. Heh. :) The point was absolutely relevant since you did not specify any conditions. In your new revision, I certainly agree - in fact, my original point already acknowledged that and more. I was just pointing out that your absolute statement was, with even a single counter-example, therefore absolutely wrong. As a programmer you gotta be careful with those corner cases.

My first thought was putting that in context with the idea of a 1000+ line function and thinking: well that's just gonna piss him off all over again. Might as well just call it thisVariableHasMoreThan1Letter or singleLetterVariablesSuck. But as a response to my point it does make sense. I do that, too, in most such situations. But not all.

Just do what apple do. Create a platform...IPOD/IPHONE They only change 3 things every 6 months..(Email forwarding (cmon we all know that took a day to write))..have a big macworld announcement and the starving clients will praise you forever. :) 6 bugs /year...think thats a programmers best average? :)

At the place where I used to work the guy who was there before me made *every* variable a global (this is in VB6) and would start with the name AAA and work his way upwards :-s

It's better than nothing I suppose, unless you're using a statically typed language, in which case it's completely useless (e.g. "int tmpInt" is redundant and a waste of brain/finger time).

I'll tell you what makes the code fairly hard to understand: having a single function which is thousands of lines long. This is idiotic and completely unnecessary - we've had procedures and functions and other abstractions since before colour TV, and their main use is to prevent thousand line functions from ever existing. IMO, tiny variable names are okay if you have quite short functions, which you really should anyway.

It did have positive benefits back in the early days of COBOL, punched cards, and things like that. Anything that saved memory was a good thing. You know, like 2-digit years.... hmmm... Yes, I have attempted to maintain programs from that era. Two-letter variable names and labels, many hundreds of gotos, even more hundred alter-gotos. Having done so, let me add something to that original advice. 2) If you use 1 or 2 letter variable names, do not leave your name in the comments at the top of the code to say what you did. 2a) Especially if one of the programmers who will read it, a few decades later, is your own daughter. She DOES know where you live.

I am talking about seeing this in high performance scientfic codes where a single function can be thousands of lines long. There is nothing wrong, IMHO, with using trivial variable names in cases where the scope of the variable is short and its meaning can be entirely gleaned from context. A classic example:
For I As Integer = 1 To 40
Item.Dat(I) = 0
NextWould using any name other than "I" make things clearer? Of how about something like:
Dim st As String
st = GetSomeData();
If Not String.IsNullOrEmpty(st) Then
DoSomethingWith(st)
EndifWould any name other than "st" be more helpful?

Jeez, if I only create six bugs per hour, I'm having a helluva day. :sigh:
Someone's gotta be the last to know, but why is it always me?
