Being bad at math

Mathematically the first row should have a style all of its own as Zero can't really be classed as either odd or even. It would make sense to style it as even though so that it had the contrasting style to row 1. Of course if you're going to allow the user a choice of what to do then you may end up asking the user what colour you want for the first third and fifth row etc and then set that to the even row style behind the scenes.

How not? I assume the "official" definition is the modulus 2, or somethign equivalent to it.
Don't attribute to stupidity what can be equally well explained by buerocracy.

Zero based indexes seem to be kicking programmer's A**es even today. I am recently using a software package that allows row styles to be applied for even and odd rows. If you apply an even style the 1st, 3rd, 5th, ... row receives the style instead of the correct row 2, 4, 6 etc. It would seem to me that the programmer that designed the underlying code used the index of a zero based index to determine if the row was even or odd. So let me pose this question: Do you think the first row should be considered even or odd?

Despite being indexed with zero, there really is not a 'zeroth' row. The FIRST row has an index of zero. So, the question is, should the term 'Even Rows' apply to the row or its index? Debate all you want - but I would wager that the majority of implementations, and the majority of technical and non technical people, when presented with a list, would count the first row as one and, therefore, odd. So the implementation you are using is, I'd say, non standard and confusing. Which one is it?

x % 2 == 0 in general. x % 2 == 1 when dealing with humans. That's my general strategy. I think I have all bases covered!

"Zero can't really be classed as either odd or even" This, in fact, is incorrect. Zero is even by all the properties of evenness.
Codemonkeys don't do it at all. Too busy coding.

Hmm Since 0 is not odd nor even from a math point of view, why not solve this problem by assuming a 0-th row can't exist? In fact row 0 is a bit strange if you think about it. So row 1 has the data of your datasource with index 0, and that's no problem in any algorithm. You just can solve it by adding 1 on your data which is indexed 0. Just make a note in the code comments. :laugh:

No, no, no. I was not saying you were like a guinea pig, only that I was using you like one. I was trying to reproduce a problem that I was having in the programming fora, where after replying to a post, I could no longer select other messages. Needless to say, I could not reproduce it. So you were even useless as a guinea pig! :laugh: :laugh: :laugh:

Well... Let's see... if seventy is 70 then eleventy would be 110. If we count in Hexadecimal, "eleventy" would be 6E, so eleventyfour would be 72. And of course we have to use something with a higher base than ten, so I think hexadecimal would be the proper choice given that it is so widely used already, but I would not cry foul if you wanted to use a system with a base of eleven... or eleventy I guess. :-D

Fine then, it's the first negative even number as well.

I think you have misunderstood. eleventyfour is the representation of the number to base 25!

Hello, Many times UIs are designed by developers. Usually this situation creates a design that follows the data instead of the User's needs/perception. I agree, it's irelevant whether the User understands the 1st row as row 0. To the User, it's the 1st row. 1 is always. Many times, great developers partner with UI designers to bridge the perception vs. behind-the-scenes infrastructure. It's always a good thing for developers to sit back and watch a complete stranger use their program... and take lots of notes. :)

Well in that case, if eleventyfour would have to be A4 as A would be the eleventh digit and four would be the fourth. Or do I need to convert the base ten number 114 to base 25, which would be 4D? Don't worry, I am not offended that I've misunderstood for it is through misunderstanding that we learn how not to understand and thus how to understand. (Ok, that's slightly akin to a quote from the invention of the light bulb about learning lots of ways not to make a light bulb, but it fits.)

it should be even ( even numbers are n = 2k ; odd numbers are n = 2k+1 ; k is a relative integer) so if you can write 0 as 2k+1 ten consider it odd :)

Users don't think in terms of zero-th row. It's only programmers who think that there is a row number zero. Usually what I consider row number 0 becomes row 1 for the user. I think that's what Ennis's point was.

I have only begun reading "GUI Bloopers 2.0", but it's clear that 'Interfaces must be in the end-user's mental model' is a major obsession with the author. Personally I would not take it quite so far, if there are certain technical terms which are worth their weight, better to teach the terms than talk around them. Of course I agree, if the GUI labels the top row as 1, it must be odd. This could be an argument for relabeling the top-row as zero at the end-user-interface, end-users ought to be able to cope with that.

Most likely they are using modulo (even = rowIndex % 2 == 0). Does it really matter? IMO: no. E.g. 0 % 2 == 0 (even) 1 % 2 == 0 (odd) 2 % 2 == 0 (even) ... for (int i = 1; i < size; i++) { if (i % 2 == 0) { final HTMLTable.RowFormatter formatter = gridex.getRowFormatter(); formatter.addStyleName(i, "kw-sortable-dark"); } }
