comment Traffic lights: why yellow before green?
Funnily enough, I've been taught both ways. In either of them, you need the "get ready" phase. You need it on bikes as well etc. I so hate it that here in France you don't have that.

comment Comparison website: simplest way to compare players through years
Provides a clue, yes. But this is not a brightness setting or a position on a webpage where 1 pixel doesn't play a role. Here it's the other way around: You want to arrive at the single correct position, which is impossible on sliders. As well, IMHO, it's not what people expect sliders to do. The standard counter field would be more suitable IMHO.

comment Why are monitors only at neck height by default?
Economy is the reason. I've got a monitor here that allows a 4D motion on its stand (height, declination, inclination, rotation). However, I suppose that it was quite expensive...

comment Why are calculator screen digits right-aligned?
@NiccoloM. Let's speak in proper words. In Latin alphabet languages, numbers are written with the most significant digit first, i.e., on the most left. In Arabic, numbers are written with the least significant digit first, i.e., on the most right. Therefore, in both systems the numbers appear the same way. (As a side note: yes, Arabic puts the digit for unities first, and after it the digit for tens, then for hundreds etc. It's only us who consider it strange.)

comment Why do idle elevators close the doors?
@Derek朕會功夫 Depends on the country I think.

comment Why do idle elevators close the doors?
@AndréDaniel However, what if the sensor fails? If the door is closed by default, both these things would have to happen to have the door open after the elevator has left: (1) the functioning motor would have to suddenly open the door, (2) the door sensor would have to fail. With the door open by default, only one of these need to happen.

comment Why did the mouse beat the light pen, paddle, and other pointing devices?
@Dunk (I'm neither an UX expert nor a massive touchscreen user) You can achieve a lot of that on a touchscreen/touchpad too, with two-finger gestures, moreover, you have a separate gesture for zooming and scrolling, which you don't have with a wheel-equipped mouse. Of course you can't simultaneously move and scroll, but you need this I think really only for gaming.

comment Might a design be “too good” for users that expect a low price?
Needed to say, the older one is more practical.

For the animation, ... under the icon (appearing and disappearing form the left to right) is an option.

@Philipp Thanks for the page. I immediately submitted one company there.

comment Should we trust a user's web browser to tell us the language/culture they want?
Always offer the user to say where he is, or where he wants you to think he is. There's nothing more annoying than Google offering me shitty French results just because I happen to be in France, and giving me no chance of customization.

comment Forgot password— show the rules for that passphrase?
For me, it's much easier to recall the password when I know the rules. Many sites have no requirements on password strength, therefore I'm always surprised that on one specific site I have a stronger password than I would likely use if the restrictions did not exist.

comment Is there a universally recognizable “Download” button?
I would say: add the filename just below the button, and make it clickable as well. That's for me always the clearest seperation from ads.

comment Why we don't use wider interfaces on wide screens
@DA01 I know. Still, on my computer, it looks fine and fills the space reasonably. Which I can't say for instance about the whole SE network.

comment Why we don't use wider interfaces on wide screens
OTOH, in most cases, you have something useful to show. I don't say that the following site has a genuine design, but it shows that there is a way ho to use cleverly the space: lilypond.org/doc/v2.12/Documentation/user/lilypond/…

comment Why we don't use wider interfaces on wide screens
I have a feeling that you have a wrong assumption about the role of wide margins in books. Could you please point out some references about the fact that they "hightlight". Most classical multi-column typography is done in such way that all the intercolumn spaces and horizontal margins have the same width.

comment Are there numbers and letters to avoid for activation codes via SMS?
On the other hand, this is more difficult for non-native speakers using your system. I can imagine my mom, who's able to use computer products in English, but is quite unable to spell anything. 6-char code is certainly easier for her than two English words, because she really has to treat the words as seperate symbols, instead of something natural.

comment On a US keyboard why is + shifted but - isn't?
@BenMiller Actually, if you watch carefully, you see that it has an (almost) full support of French as well, the only thing that seems to be missing is ï, but it's not so much
