Can elves, half-elves, warforged, and/or kalashtar be affected by Dream of the Blue Veil?

The Fey Ancestry racial trait shared by elves (Player’s Handbook, p. 23) and half-elves (p. 39) states “magic can’t put you to sleep.” Warforged’s Constructed Resilience trait is similar: “You don’t need to sleep, and magic can’t put you to sleep” (Eberron: Rising from the Last War, p. 36). Kalashtar have a racial trait called Severed from Dreams, which reads (p. 31):

Kalashtar sleep, but they don’t connect to the plane of dreams as other creatures do. Instead, their minds draw from the memories of their otherworldly spirit while they sleep. As such, you are immune to spells and other magical effects that require you to dream, like dream, but not to spells and other magical effects that put you to sleep, like sleep.

The spell dream of the blue veil begins with the following paragraph (Tasha’s Cauldron of Everything, p. 106; emphasis mine):

You and up to eight willing creatures within range fall unconscious for the spell’s duration and experi­ence visions of another world on the Material Plane, such as Oerth, Toril, Krynn, or Eberron. If the spell reaches its full duration, the visions conclude with each of you encountering and pulling back a mys­terious blue curtain. The spell then ends with you mentally and physically transported to the world that was in the visions.

A sidebar next to the spell reads (p. 106, emphasis mine):

Transit between [different worlds on the Material Plane] is rare but not im­possible and can be accomplished in various ways. […One] method is the Dream of Other Worlds; trav­elers fall into a deep slumber and dream themselves into a new realm. The spell dream of the blue veil em­ploys this method of transit.

My question is, can elves, half-elves, warforged, and/or kalashtar be affected by dream of the blue veil?

My current interpretation of RAW is that the answer is “no” for all four creatures. The sidebar outright states that dream of the blue veil induces “slumber” (thus excluding elves, half-elves, and warforged from being affected) and causes its targets to dream (excluding kalashtar). However, there are a few reasons I might be wrong.

Nowhere in the spell’s actual text do the words “sleep,” “slumber,” or “dream” appear. It refers only to creatures becoming “unconscious” and experiencing “visions.” Contrast this with sleep, which “sends creatures into a magical slumber” and refers to its affected targets as “sleepers” (PHB, p. 276). Contrast also with dream, which “shapes a creature’s dreams,” doesn’t affect a target until it’s “asleep,” and explicitly states that “Creatures that don’t sleep, such as elves, can’t be contacted by this spell” (p. 236).

Commenters in this Reddit thread largely agree that the lack of sleep- and dream-related language in the spell’s text means RAW is that kalashtar can be affected. One commenter points out the similarity to the spell catnap, which can affect elves.

Maybe the Tasha’s Cauldron sidebar, like the title of the spell, is simply some extra lore that doesn’t affect gameplay. However, I see no reason to exclude sidebars from RAW. Many important rules, such as the ones for hiding (PHB, p. 177) and some rules governing wizards’ spellbooks (p. 114), appear only in sidebars.

Another Reddit commenter points to “Spell Spotlight: Dream of the Blue Veil,” a D&D Beyond article which contains the following sentence:

A kalashtar wizard who uses the dream [created by dream of the blue veil] to flee the agents of the Dreaming Dark by escaping to Krynn may buy themself enough time to gather new allies, new resources, and return to Eberron with a bold new plan to defeat their enemies.

This obviously implies that kalashtar can be affected by the spell. I imagine that this could be an oversight, and I don’t especially see why this article should be considered RAW. But again, I could be wrong.

Use XML Based Sitemap and/or Static Page Sitemap?

I have a question about which sitemap to use – XML based that is sent to Google Search Console or static HTML based sitemap that is added to the website footer.

If you search "dump trucks for sale", you will find this result in the third position: https://www.commercialtrucktrader.com/Dump/trucks-for-sale?category=Dump%20Truck%7C2000609

Our website uses faceted navigation to filter inventory results, like the Commercial Truck Trader website example I posted regarding a search query.

I see the Commercial Truck Trader website has a sitemap link added to their footer. This is a static HTML based sitemap that can help the user navigate parts of the website.

Do you think the search query "dump trucks for sale" is showing the Commercial Truck Trader website in the third position on a serp from using a static HTML based sitemap that is added to the website footer, or from an XML based sitemap that is sent to Google?

I want to use the output of Solve and/or Reduce in next steps. But the output comes in the form of a rule [duplicate]

In a program I want to use the output of Solve and/or Reduce in next steps. But the output comes in the form of a rule, where what I want is the numerical solution. Here is an example. Say I write s=Solve[x+2==5,x]. In the next step I want to use this solution, so I write: y=2 s +3. This returns {{3+2(x->3)}}. This is a very basic need, but hours combing through the documentation leads nowhere.

Can the School of Conjuration wizard’s Minor Conjuration feature be used to summon rare, expensive, and/or consumable spell components?

Can the School of Conjuration wizard’s Minor Conjuration feature (PHB, p. 116) be used to summon rare, expensive, and/or consumable spell components?

It seems to fit within the scope of the feature in a rules-as-written manner, and I am inclined to allow it – but not having fully experienced the dynamics of higher level play where it might come more strongly into play, I have some uncertainty.

Do the Hunter ranger’s Extra Attack, Whirlwind Attack, and/or Horde Breaker features work together?

At level 5, all rangers get the Extra Attack feature:

Beginning at 5th level, you can attack twice, instead of once, whenever you take the Attack action on your turn.

At level 3, the Hunter ranger archetype gets Hunter’s Prey, which lets them choose from 3 possible features. One option is Horde Breaker:

Once on each of your turns when you make a weapon attack, you can make another attack with the same weapon against a different creature that is within 5 feet of the original target and within range of your weapon.

At level 11, Hunters gain the Multiattack feature, which lets them choose between the Whirlwind Attack and Volley options. Whirlwind Attack says:

You can use your action to make a melee attack against any number of creatures within 5 feet of you, with a separate attack roll for each target.

Am I right that Whirlwind Attack can not be used with Extra Attack, because you do not use the Attack action to make a Whirlwind Attack? Generally, can Extra Attack be used with any of the Hunter ranger’s special attacks?

I think with Horde Breaker, the “different creature” clause excludes any creature originally targeted with Whirlwind Attack. This means unless you have a reach weapon, Horde Breaker is useless with Whirlwind Attack. Am I mistaken?

Does Two Factor Authentication (2FA) prevent Phishing and/or Man-in-the-Middle (MITM) attacks?

While 2FA is clearly an improvement over only a single factor, is there anything which prevents an adversary presenting a convincing sign-in page which captures both factors?

I realise that technically a MITM attack is different to a Phishing attack, though at a high level they’re very similar — the user is inputting their credentials into an attacker-controlled page and the attacker can then input the credentials onwards into the real page.

Does the Arcane Archer’s Shadow Arrow inhibit blindsight, tremorsense, and/or truesight?

Shadow Arrow:

You weave illusion magic into your arrow, causing it to occlude your foe’s vision with shadows. The creature hit by the arrow takes an extra 2d6 psychic damage, and it must succeed on a Wisdom saving throw or be unable to see anything farther than 5 feet away until the start of your next turn.

Blindsight:

A creature with blindsight can perceive its surroundings without relying on sight, within a specific radius.

If a creature with blindsight (like a Flying Sword) fails its saving throw against an arcane archer’s Shadow Arrow, is its ability to perceive enemies via blindsight restricted? Would creatures with truesight or tremorsense be handled the same way?

It seems to me that this is fairly straightforward, but upon reading this question about opportunity attacks, there seem to be cases where the word "see" is used more generically as all forms of perception.

When MAC flooding, why would an attacker specify IP addresses and/or TCP ports?

I’m specifically referring to the macof tool (part of the dsniff package).

As I understand it, MAC flooding is meant to overload a switch’s CAM table, which maps MAC addresses to switch ports.

Where does specifying IP addresses and/or TCP ports fit into this?

Does doing so allow an attacker to bypass a Layer 3 switch’s filters, ones that filter traffic based on IP addresses and/or TCP ports?

Which would be the best “keyfile” for KeepassXC and/or Veracrypt?

I am a Mac user. I opened a keyfile generated by Veracrypt and one generated by KeepassXC. The texts in both of them were quite short. Which keyfile is best (i.e., most random and harder to break through): one generated by Veracrypt or one by KeepassXC?
OR: Is it best to create my own keyfile?: I can open a photo with TextEdit, copy and paste the gibberish that shows up in an empty TextEdit file, save and use that as my keyfile. Is that be better?

I also wonder if it is best to use another type of file (a .jpeg photo, maybe) as a keyfile. My thinking is: files generated by Veracrypt and KeepassXC may stand out (assuming someone broke through my device and started looking).

Would anyone recommend embedding a file in a picture (steganography) and use it as a keyfile instead? How can I do the embedding in Mac? I am familiar with Terminal.

Thank you in advance.
