I don't like code reviews

so we disagree to disagree then? I find the later no easier.. In fact some interesting brain chemistry must be at work here... I was reflecting how physicist (that's my background), prefer short name too, i.e. it'e
E=mc^2, notEnergy = Mass * SpeedOfLight^2, to vindicate me... Anyway, regardless, it's more interesting to consider what psychological factor lead from one to another. I know that for me, bad work memory favor short variable names. Long variable names are just too hard, I have to read the statement 2 or 3 times to get it. 1 or 2 time to get all the variables involved, and one more time to get the computation. I can get all that in one go/read with shorter text - i.e. short variable names and simple math. Maybe I have some sort of dyslexia or something, I tend to not read big wall of text very accurately. Not just in code but also in plain English... Hence for me shorter variable name increasing my accuracy / understanding... :sigh:A new .NET Serializer All in one Menu-Ribbon Bar Taking over the world since 1371!
Another angle: I do use single-letter Field names when: 1) they are used only in the scope of a Method/Function and 2) they are, imho, easily recognized, in context, as representing logical attributes. So, in a Method that takes a Rectangle as a parameter: I might, as the need arises, use 'w for 'Width, 'h for 'Height, etc. I only use 'i, 'j, 'k in for loops. But, if an employer wanted longer names, no problem; the 'name issue is not a "religious" issue for me, but, I value consistency.

Yeah, glad to know I am not alone! :) Seeing all the strong opposite reaction, I am starting to believe, just as long variable names are a real impediment to my comprehension. Many might have a sort of opposite problem. Though, and I am digressing here, from the strongly opinionated people I fear an even worst problem. Focus on names at the detriment of the logical operation...

I think you are seeing a polarization that is not as intense as you may be experiencing it. I see the gist of the comments here as focusing on code readability, maintainability ... in the context of a project with multiple programmers, and a code base where any accidental semantic clash, or mis-interpretation of the meaning of names, can have disastrous consequences, cause needless confusion, etc. I am reminded of when I joined the Illustrator team at Adobe, and, out of curiosity, looked in the source for functions that converted whatever to hexadecimal: there were 17 different functions, most of which were duplicates ... that no one dared to change :)

ok, sometimes there are very good comments... but every time the reviews are waaaaay too slow. and very often there are comments which are both useless, antagonistic and a big waste of time... for example I don't see the point of long variable name nor do I like them, particularly for a short liner like
double Value
{
get
{
var x = Calculation();
return flag ? x : 2 * x;
}
}And have to wait a few more hours because I was told 'not to use short variable name'. Unsure I renamed 'x' to 'aNumber', but that irks me... On top of that, that might be just me with my bad memory, but I find long variable name harder to read! :omg: For example a simple expression like
a = b + ccan confuse me if you write insteadmyobjectBlu = aCycleValueOrdinal + meteorStrikeOffsetTime.

Variable names should be long enough to explain what they do but short enough to be succinct. Very long names show you haven't thoroughly worked out what they are for or you are being too restrictive. For example, the other day I was writing some code that I hadn't thoroughly thought through and I created a variable called something like
locationOfCommonSharedValuesBeforeTheConfigurationWasJoinedToAnotherEnvironmentsConfiguration. After much soul searching, it is now calledoriginalSharedValues. -

Without greater context, I can't tell whether "b + c" is the correct thing to do to get "a". Given your second example however, if I know that in order to get myobjectBlu, the equation needs meteorStrikeOffsetTime to be multiplied by a constant before being added to aCycleValueOrdinal, then I can spot this. [Edit] Just being devil's advocate. I have to imagine that someone reviewing this would see the greater context and not just look at the one line.

Here's my comment - do NOT use var! Using var instead of double forced me to look in a second place in your code to figure out what I was reading. var is an abomination.

The code bases of the existing Adobe products I worked on, PhotoShop, Illustrator, were the opposite of design by committee: they grew by accretion. New, "hot," features always took precedence over any systematic re-org. By the way, I have complete respect for the world-class programmers I had the chance to work with, and, I felt continually humble in their presence ... for good reasons: I was a one-trick pony :) When they did the PC version of PhotoShop, they found the Mac code (using the MacApp framework) impossible to port "native," so they re-implemented MacApp on Windows, which took a tremendous effort.

I agree, the length of a variable name should be proportional to its scope and visibility. The reader should be able to see a one-letter variable and just know that it has only local scope. Any developer who gets confused by such a thing does not belong on my team. The fewer the characters, the easier to read. :-D

I use "i" in for loops. That's it. Edit: Also using "x and y" currently: for position coordinates.
