comment Why do idle elevators close the doors?
@Pharap: another case, suppose a really famous restaurant is in the penthouse of an otherwise sleepy office building. Most people eating there are outsiders coming from GF, rather than the office workers. During lunch time, it would make sense to always have one lift stationed on the penthouse and one on GF, as probabilistically those are the highest traffic area. Also, serving the penthouse the fastest will probably leave the lift with room to spare to pick up passengers from other floor, while additional delay on those floors can mean that the lifts will always be full on GF and penthouse.

comment Why do idle elevators close the doors?
@Pharap: in most places, the entrees and exitees are not uniformly distributed but rather follow a predictable pattern. Suppose that you know that at certain hour, 95% of users will be coming from GF going to a uniformly distributed destination and the 5% are uniformly distributed; if the lift waits on its last destination floor, then 95% of people would have to wait for the lift to move N levels (N/2 to go to GF and N/2 to go to their destination). OTOH, if the lift has a home floor, 95% of people only have to wait for an average of N/2 floors. Also lifts needs to accelerate to speed.

comment Why do idle elevators close the doors?
@Pharap: more important than optimizing energy for elevator algorithm is to optimize for travel latency/delay (between request to arrival) and starvations/fairness (can't have people in the top-most floor always being the slowest to serve). In busy offices where the direction of travel is highly asymmetric during different times, elevators may be programmed to have most of the cars wait in the ground floor in the morning when most people are going up and to spread across higher floors in the evening where most people are going down.

comment Why do some users complete forms all in capital letters?
Add to that, Peggy then moved to another company, a startup who hired her for her expertise, but they used a different version of the software or even different software, which does handle casing properly. She taught the juniors how to case it like in her old company. Then she left for another adventure, now nobody knows why in this company all their database is in uppercase.

@MervinJohnsingh: put it to address book, problem solved.

comment Which anchor text variation provides the best experience?
Someone totally unfamiliar with computers that they don't know what links looks like probably wouldn't know what "click" means either, and they're probably going to be using a tablet or mobile phone, in which case they'll be looking for a mouse to connect to their phone.

For an opposing case, Twitter's Bootstrap uses vertical hamburger menu.

comment Is there an html character entity which can represent “Admin”?
@JukkaK.Korpela: yes, you're correct, that, and to add the word admin as a hint what it means whatever symbols you end up using.

comment Best way to convince managers importance of typography
I came reading the articles to find how much the effect of poor typography is to believability of an article or conversion rate, which is probably what most marketers would be concerned about. While most of the articles claims that typography affects these (and I don't doubt that poor typography could hurt these factors), none of articles mentioned how large the effect actually is.

comment Best way to convince managers importance of typography
Combine misleading graphs, lots of anecdotes, no mentions of effect sizes, citing experts opinions outside of context, lack of reference that can be followed, and abuse of statistics hidden in plain sight, and you can convince people of anything. I read all the articles you mentioned and I think they all provide very poor evidence for their claims.

comment How can wiring systems be designed to not rely solely on colour?
The idea that I had is similar to this, but I'd also suggest using thinner line for 0 and thicker line for 1, as to not rely on color alone. Additionally, to maintain usability for non color blind users, the code could also represent the 6-bit RGB color code for the cable's color (e.g. red = 110000), thus you won't need separate manual for normal and color blind people. Alternatively, the code could be designed so it can be read backwards and forwards without changing meaning, allowing easy reading when the cable is aligned the wrong way, and no need for the special blue stripe.

comment Is clockwise or counter-clockwise rotated text easier to read?
Most computer screens are oriented landscape, so they do not lack horizontal space as much as vertical space, so I would say, scrap the vertical text to start with.

comment Is there a good alternative to zebra stripes when rows use drag-and-drop reordering?
Why not just highlight on hover? That works well on all devices that have pointing device. On touchscreen, you can highlight on single tap.

comment What's the Friendliest 'Back' Button?
+1 for providing multiple different ways, but IMO having both the "back to X" button and the close button is probably too similar that people will be wondering if there's any difference. I'd also suggest making the browser's Back button close the modal as well.

comment Good UX for inputting 14 different times
Then they probably should get a numeric keypad with tab keys or figure out how to remap their keyboard. In any case, this is a UI for entering 14 items, not 1000, there's no reason to break the convention for this.

The enter key should not move input to the next, that's what the Tab key is for.

What do you mean exactly by "traditional" homepage? A wall of text with some spec tables sprinkled around?

comment Why do the popular browsers copy each other's user interfaces?
All TV remotes have their power on the top, a 3x3 digit keypad with the lower numbers on top, and below that keypad are the volume buttons and channel buttons and other sorted buttons. They all have strikingly similar basic layouts even when they come from different manufacturers. Do they copy each other?

comment Is a book more user friendly than an e-book?
@ColinSharpe: can you get a popup story book in an ebook format? Can you get an interactive, multimedia story book in paper format? Just because we both use spoons for the soup doesn't mean that either of us is wrong when I used a spoon to eat a cheesecake while you used a fork for the same.
