In combat, how many creatures can be in a 5 foot square at the end of a turn? [closed]

In D&D 5e, basically all PCs fit in on a 5 foot square. I want to figure out how much that 5 foot square can hold at end of turn by rules as written.

My first estimation is 3 people. Using the rule that allows creatures to use other creatures that are a size category bigger then them as a mount, allows for the situation: A centaur barbarian counts as large for carrying and pushing so with some plate armored fighter on top, duel wielding lances, a half-ling sits on the fighters shoulders, gets us to three.

That is 3, but can we get more?

Why is targeting an adjacent attacker with a 5 foot cube area attack considered a ranged attack?

An opponent has moved adjacent up into a character’s face and swung at them. On their turn, in retaliation, the character would like to attack back with their favoured cube area attack, made at the size of a 5 foot sized cube to be ergonomic. Oddly the rules as written (see below) seems to qualify this attack as a ranged attack even though the target is adjacent and every other area attack also containing the attacker would not. Is this an oversight, an intentional design decision, or is there anything I’m overlooking that makes this ruling invalid?

The rules leading me to this conclusion appears here:

Ranged Attacks in Melee

Any time you make a ranged attack and there is an enemy within melee reach of you, you have disadvantage 1 on your attack roll. Area attacks are considered ranged attacks if the area does not include at least one space adjacent to the attacker.

The 5 foot cube placed on the attacker’s square does not include at least one space adjacent to the attacker but it does include attacker’s square itself which intuitively feels like it shouldn’t be a ranged attack as well as other area attacks. RAW however, this means it’s a ranged attack and imposes disadvantage 1. To me a more intuitive ruling and writing of it would be:

Ranged Attacks in Melee

Any time you make a ranged attack and there is an enemy within melee reach of you, you have disadvantage 1 on your attack roll. Area attacks are considered ranged attacks if the area does not include the attacker or at least one space adjacent to the attacker. (changes italicized)

Are there existing rules or other evidence the designer’s intention was for this scenario to be a ranged attack? If so, why only 5 foot cubes and not every other area effect (they have to include a square adjacent to the opponent as well)? Is there perhaps another mechanical reason I can’t find that this attack should be considered ranged? Is the attack simply supposed to impose disadvantage 1 and being considered ranged is simply a byproduct?

In the case that it shouldn’t be considered ranged (or only considered ranged for the purpose of disadvantage 1), I would like to revise this confusing wording. I have found the Open Legends repository and my intention is to submit a pull request if I understand the rules correctly and this ruling is against the RAI. However, I’m asking my question here first to gain assurance, as I know that I am very new to the system and may be overlooking something.

When did 5 foot squares become standard in D&D?

Perhaps showing my age here, but in “The Good Old Days”, 10-foot squares were a standard map size. Each square on the map was 10 feet, and a 10-foot wide corridor was normal.

Now, having started gaming again, it seems 5-foot squares are standard.

So my question is: when did this change happen? Was it 3rd edition?

And if I’m trying to convert one of my old D&D modules to 5e, should I just make all the passages 2 x 5-foot wide instead of 1 x 10-foot wide?

Uac interaction for people with physical disabilities (no keyboard, mouse or foot pedals)

Is there any way for a user to interact with a uac prompt for admin privileges despite not being not able to use a physical keyboard, mouse or foot pedal? I use both voice and eyetracker software, Dragon naturally speaking and Optikey,but neither can interact with uac, AFAIK. One workaround, that I use is using something like Teamviewer to interact with the uac prompt. This is not ideal, as it requires a second accessible computer. Is there another approach that obviously doesn’t need to disable uac either? Perhaps something like a physical key (e.g. Usb)?

Time needed to board Sandefjord-Stromstad ferry on foot

I am taking a ferry (Color Line, MS Color Viking) from Sandefjord (Norway) to Stromstad (Sweden). We will be two people with no car and minimal luggage (we arrive to Sandefjord Torp airport with hand luggage only). Is getting on the ferry in such case simply walking in and showing the ticket, or is there any more complicated procedure to go through? How long before the departure should we turn up?

How to leave Beijing airport (PEK) by foot

I have 5 hours between daytime flights in Beijing Capital airport (terminal 3), and my challenge is to walk out of the airport to eat a bowl of soup at any small local restaurant outside the airport.

The airport seems to be surrounded by semi-urban areas, so finding some food is probably possible:

The main difficulty will probably be to find a walkable way out. How to achieve that?

Google Maps shows walking directions, but it makes me walk on roads without sidewalks such as this one, so I think it can not be trusted in this area:
