comment When formatting numeric data with rounding, should the total line reflect the total of the rounded data, or the raw, unrounded data?
I believe you are wrong. Mathematically, at least. Rounded numbers should be used. That's why we have different rounding methods: to take into account the situations where it is used. Eg. "Bankers' rounding" where you round 1.5 to 2 and 2.5 to 2. This will ensure that the sum (and thus the average) is less biased by the rounding.

Your example is wrong. A rounded version of ´(2÷3)´ would be ´0.6667´, thus adding up to ´1.0000´.

You should sum the rounded numbers. Once you decide a certain level of precision, you should stick to that level of precision.

comment Positioning Enter/Backspace Keys on a Numpad
@Justin: I'm answering the question "where to put the [enter] and [backspace] keys". My suggestion is to put [backspace] next to the input-field instead of the pad itself. The screen-shot is just an example of how this is done in another UI. The reference to other solutions is also an encouragement for Carl to peek on others work to ensure a certain level of consistency across the tools for the end-user. There's no need to re-invent everything ;-)

Ah, OK. That was unclear in the question...

comment Should I use the terminology left/right click?
Interesting question. I believe "right click" is interpreted as "secondary button" for left handed people as well.

comment Is there a reason for the recent shift to inner zoom images on ecommerce websites?
I doubt that this trend is related to UX at all. Some developer stumbled upon a nice technical solution, and added it as nice-to-have feature. Without any objections afterwards, and definitely without any user research up front. I bet that any quick'n'dirty DIY user test would prevent this. The need to see details are probably there, but the implementation/solution is just plain wrong.

comment Checkboxes vs. Radio Buttons
@LDMediaServices: How would you know that the user explicitly answered "No" if a single checkbox is unchecked? Sometimes it can be useful to have Yes/No answers, where none are pre-selected. It gives you a third implicit option. IMHO/IMHE, checkboxes are designed for "I agree on this"-situations. And they are not suitable for "I disagree by leaving it unchecked"-situations. (It totally depends on the context, and what you need for your data collection.)

@L.Möller Thanks! Should have been "related to the header".

comment detect when 3 boolean variables are true at the same time?
Our brain's pretty good at matching similar stuff (search for Gestalt). Eg. three in a row on a 1 arm bandit: gunmin.net/gunmin-slots.jpg and empty "pie charts" in TP: upload.wikimedia.org/wikipedia/commons/thumb/7/77/…
