comment Why do showers have “hot” and “cold” knobs rather than “temperature” and “quantity” knobs?
Huge advantage of the lever mechanism is that it's basically maintenance-free as it's ceramic seals don't wear off and always seal tight while the taps with knobs (valves) start to tap over time and need replacing of the seals. And the levers are easier to operate.

comment Why do showers have “hot” and “cold” knobs rather than “temperature” and “quantity” knobs?
"Mixing battery" means it has just one outlet for both hot and cold water, so the thing in the second picture also qualifies as "mixing battery". It's been the default in continental Europe for ages. The only place I've seen two separate taps is England (and it's disappearing there as well).

comment What is the difference between human factors and UX design?
See this great answer from aviation.se. The gist is it is not unusually complicated if you consider that your computer has over hundred buttons on it.

comment Fibonacci pagination
The Discourse approach would be great if it had some support for the browsers and the protocol. But currently it breaks searching in a way that is not easy to work around (I do agree pagination is broken and would like to see a fix; just saying it does not exist yet)

comment Email as username during signup/login? Your experience?
+1000000 for OpenID. It is easy for the user and more secure.

comment Email as username during signup/login? Your experience?
The first point is in part consequence of the second. If your username is taken on some services, you end up with different usernames and that makes them difficult to remember.

comment Is red an acceptable colour for a submit button on a form for a purchase or booking?
Note that the screenshot in the question does include a green-gray button, so the "suspicious" clause applies.

comment When does delete not mean delete?
If a key is user-defined, re-creating entry with the same key should IMNSHO resurrect the deleted entry. Because if it is a natural primary key, chances are the new entry does indeed represent the same entity as previously.

comment How to highlight the selected option when there are only 2 elements
More vibrant v.s. more bleak colour looks good, but for me, intuitively it's definitely the larger that is selected (because smaller might be pressed, but larger is highlighted).

comment How Do I Avoid Users Becoming Numb to Warnings?
Microsoft is setting a very poor example here, because their common dialogs don't support setting text for the buttons. Gtk and Qt have better common dialogs where other buttons can be easily specified.

comment Forcing users to use a particular pattern for passwords
@rit: Right. Appears I was mistaken about what OAuth is. OAuth is for authorization and that's not subject here; I should have only said OpenID.

comment Forcing users to use a particular pattern for passwords
@rit: OpenID (and OAuth) means you don't ask the user to log in with existing login on any particular service, just any existing login they trust and supports the relevant protocol. I, for example, log in to SE with OpenID against a script I've set up on friend's server just for such uses. There are also services that just provide OpenID.

comment How slow can an app be to keep feeling responsive?
How do you plan to present the suggestions? Just inserting the suggestion selected? Opening pull-down list below cursor? Will it slow the user down in any way? And how many characters do you expect they have to type between getting anything useful?

comment Forcing users to use a particular pattern for passwords
You can avoid the dilemma by using OpenID and OAuth. Most users will give you their Google or Facebook login, which has strong password policy, but is only one password that they already memorized.
