Why don’t adventurers suffocate in lower levels of dungeons?

Why don’t adventurers (and monsters) suffocate in lower levels of dungeons?

I asked a question about this on Physics to check my reasoning. Why does Nitrogen not sink in air if other dense gases do? An answer states that CO2, which is a product of exhalation, will sink to lower levels in enclosed spaces. There is also a hazard in mines generally from gases seeping out of the rocks.

Question

How do PCs and NPCs survive in such conditions? If there is some form of ventilation to the outside world, can explorers escape through the ducts?

Some addons don’t start

Some addons don’t work or rather don’t start.
For example, Alexa Rank Checker works well.
But Alive check, Anchor Text & Article Scraper does not start.

My scrapebox is up to date (2.10.19) and so are the addons.

What can I do?
Please help!

What happens if you don’t sleep?

The description of a long rest says:

A long rest is a period of extended downtime, at least 8 hours long, during which a character sleeps or performs light activity: reading, talking, eating, or standing watch for no more than 2 hours.

A recent Sage Advice, while discussing whether elves need 8 hours for a long rest, also clarifies that a long rest need not necessarily include sleep, and that the only activity limited to 2 hours is the standing watch:

A long rest is a period of relaxation that is at least 8 hours long. It can contain sleep, reading, talking, eating, and other restful activity. Standing watch is even possible during it, but for no more than 2 hours; maintaining heightened vigilance any longer than that isn’t restful. In short, a long rest and sleep aren’t the same thing; you can sleep when you’re not taking a long rest, and you can take a long rest and not sleep.

Presumably, though, most humanoids need to sleep (and elves need to trance) to avoid exhaustion. Yet I cannot find any rules relating to applying levels of exhaustion to characters who neglect (or are unable) to sleep. I don’t think the forced march rules apply here, as long as the characters limit travel/adventuring to 8 hours/day and spend the rest of the day doing downtime activities and resting.

I am thinking primarily of a situation where hallucinations, nightmares, or a noisy environment prevent a character from sleeping when he or she attempts to do so.

What/where are the rules that require a character to eventually sleep or trance? And what are the penalties for not doing so. The sage advice says sleep is independent of rest, so what is the penalty for not sleeping if the character has taken a full long rest consisting of only light activity.

Most website visitors don’t have Java enabled

So, for the first time ever, I had a look at the "Java Support" dimension in Google Analytics. According to that, most of our visitors don’t seem to have Java enabled (115,844 vs. 7,540 page views). I’ve read stats that approx. 1-3% of people have Java disabled in their browser, so what’s going on on my website? How shall I interpret this data from Google Analytics?!

Our website is based on Javascript and won’t work without it. That’s why I find it odd that visitors without Java support would spend an average of 2:45 minutes on it. Any explanation or advice is greatly appreciated!

Trying to ask the moderator a question but don’t have 20 rep to ping in general Chat. How do I PM the moderator?

Last post was deemed an advertisement by moderator. Not trying to place ads but see if anyone wants to play a new game we have. How can you do that without mentioning the name of the game? It is already published, just new and not as well known as DnD and other stuff you can mention. And just because it is OUR game, the mod sees it as self promotion. Should I log in as someone else and lie and say "Wow guys, I just learned of an awesome new game that isn’t my own… let’s play."

Not trying to be cheeky here, and didn’t want to say all this in public here, but really, 20 rep just to talk on general chat to ping moderator? Come on.

Rewrite a folder name using .htaccess don’t want to work

I am wondering, why folder renaming doesn’t work. RewriteRule ^pl/(.*) public/$ 1

Lets say I have a url like:

site.com/public/index.html 

Now I want to rewrite the url to

site.com/pl/index.html 

"pl" is not a folder rather just a name!

The rest works fine. Why just that one rule doesn’t work?

my .htaccess

RewriteEngine on RewriteRule ^dekoracyjne.html$   decorative.php [NC,L] RewriteRule ^pl/(.*) public/$  1 RewriteRule ^dekoracyjne/(.*) decorative/$  1 RewriteRule ^techniczne.html$   architectural.php [NC,L] RewriteRule ^techniczne/(.*) architectural/$  1 RewriteRule ^show.html/([-\w]+)$   show.php?id=$  {products:$  1} [L] RewriteRule ^p.html$   product_configurator.php [NC,L] RewriteRule ^show_c\.html/([-*\w]+)$   show_c.php?cat=$  {catcolors:$  1} [L] RewriteRule ^(product_configurator)\.html/(\d+)&([-\w]+)$   $  1.php?prometheus_id=$  2&id=$  {products:$  3} [L] RewriteRule ^(ss_c)\.html/(\d+)&([-\w]+)$   $  1.php?prometheus_id=$  2&id=$  {products:$  3} [L] # Rewrite other ".html" requests to ".php" RewriteRule (.+)\.html$   $  1.php [L] 

I am trying to convert my SQLite database into Postgres database, but I don’t know how to convert name TEXT (32) NOT NULL

CREATE TABLE integrals (    id SERIAL PRIMARY KEY NOT NULL UNIQUE,    name TEXT (32) NOT NULL,    ip TEXT (32),    posx REAL NOT NULL,    posy REAL NOT NULL,    port INTEGER,    image INT,    zones TEXT,    pass TEXT ); 

This is my SQLite generated database, and I am trying to convert it, but I am very new to Postgres.

Why don’t changelings reveal themselves?

I am preparing to run my first Changeling: The Lost game and just read over the rule book. One thing I don’t understand is why the mortals don’t know about the Changelings.

Vampires have strong reasons to hide from the mortals. The mages in Mage: The Awakening would actually have a hard time revealing themselves even if they wanted to. But Changelings can reveal themselves to mortals (p. 108). There are some negative consequences to doing so, but those consequences are primarily supernatural in making it easier to track the Changeling. I haven’t found anything about the mortals forgetting or rationalizing a changeling that has scoured her mask or overt use of contracts. In, fact there are some advantages to forming a contract with mortals and the types of contract discussed might involve the human knowing the changeling is at least somewhat supernatural.

I see plenty of reasons an individual changeling may not want to out themselves specifically, from the risks of attracting the Huntsmen to changing relationships she doesn’t want to change. But I don’t see anything preventing the world from knowing about the existence of changelings in general.

So, why don’t the mortals know, at least in general terms, about the existence of changelings and the True Fae?

Making a notebook unsavable, so that I don’t accidentally mess up the code

I have an algorithm in a notebook that I don’t want to change. I used it regularly. I’m afraid I might accidentally modify a parameter. I’d like the notebook to be executable, perhaps editable, but permanently unsaveable. I’ve tried to accomplish this byHowev Preferences>Advanced>OptionsInspector>NotebookOptions>FileOptions>Savable->False. However, it appears that this setting is lost when I quit Mathematica. Is there a way to make it permanent>
