[ Politics ] Open Question : Black Lives Matter protesters chant in DC: ‘Israel we know you, you murder children too’?

‘It was only a matter of time before the DC protests turned anti-Semitic’ Black Lives Matter protesters marching through Washington, D.C., on Wednesday were captured on video chanting, “Israel we know you, you murder children too.” wake up America–democrats want to burn your country down.,

In general, how does a DFA know how to successfully process a string the intended way?

Suppose we have:

$ $ A\text{ }\colon=\{x, y, z\}$ $

$ $ M\text{ }\colon=\text{some DFA using A}$ $

$ $ S\text{ }\colon=xyzxyzxyz$ $

Intuitively, one might say $ S$ is fed to $ M$ on a per-character basis.

This means that somehow we have an undisclosed mechanism that can tell where a symbol starts and ends.

One might say, simply use the maximum valid substring similar to how Lexers tokenise plaintext. To that I say, suppose instead that we defined $ A$ as: $ $ A\text{}\colon= \{x, xx, xxx\}$ $

Now we have 3 unique symbols, that, as it so happens, using the maximum valid substring will yield in a restriction to what our our $ M$ can actually process, because any string longer than 2 characters will always be assumed to start with $ xxx$ rather than perhaps, $ x$ and $ xx$ .

One way I see around this is to actually have a character synonymous to a symbol. That is, $ x$ and $ xxx$ (from $ A$ ) are both a single character each.

Thoughts?

How to estimate the complexity of sequential algorithm given that we know the complexity of each step?

First case: I was stumble upon a two step sequential algorithm where the big O complexity of each step is O(N^9).

Second case: Also if the algorithm have three steps where the complexity of step 1 is O(N^2), the complexity of step 2 is O(N^3) and the complexity of step 3 is O(N^9)

What would be the complexity of the first case and second case ?

Do Sorcerers need to know a lot of attack spells?

I was building a Sorcerer character I had in mind for high-level campaigns (e.g. starting at 10th) and noticed that while I was planning and selecting his spells known, I seemed to gravitate mostly toward attack spells. Then I started thinking: I can pretty much use any one of these spells as many times as I want within the limits of my spell slots, would it really do me that much good to have this many of my spells be attacks? I’ve kinda made a point to grab at least one spell per spell level that can deal multiple damage types and/or at least one Magic Missile variant at appropriate spell levels, so should I bother with any more damaging spells with a selection like that or should I look for more utility/support spells, instead?

In the Telekinetic feat for Psionic Options Revisited, what if you already know the cantrip?

The Telekinetic feat in the UA 2020 Psionic Options Revisited describes learning the Mage Hand cantrip, but without any components, and making it invisible. It says that if you already know the spell, that its range increases by 30ft. Is that on top of the no components and invisibility? Or does a spellcaster only gain the extra range?

Can I Minor Illusion a 5ft box around myself to write notes when I know I am being scryed on?

My party is being scryed on by an enemy. We are all low level and don’t have access to second level spells yet. Can I get out paper and quill, cast minor illusion around myself as a 5ft cube of hollow stone, and write down sensitive information. Then pass the folded up paper to a party member and cast the illusion around them so they can read it? My theory is that because the scrying sensor is always 10ft away from the target they would just see a block of stone.

From Scrying:

On a failed save, the spell creates an invisible sensor within 10 feet of the target. You can see and hear through the sensor as if you were there. The sensor moves with the target, remaining within 10 feet of it for the duration.

How does WordPress know wich language is chosen when there is a database connection error

When I have a db connection error in WordPress, WordPress shows the following error:

Error establishing a database connection

But when my website’s language is set to german, the message shows:

Fehler beim Aufbau einer Datenbankverbindung

Which is basically the same error message but in german. But how does WP know which language is chosen, since it could not connect to the database server?

Is it reasonable to think that most magic users would be familiar with the spell Silence and thus know easy ways to counter it? [closed]

The spell Silence as described in the PHB:

For the Duration, no sound can be created within or pass through a 20-foot-radius Sphere centered on a point you choose within range. Any creature or object entirely inside the Sphere is immune to thunder damage, and creatures are Deafened while entirely inside it. Casting a Spell that includes a verbal component is impossible there.

The spell is obviously a useful tool against magic wielders, but I’m trying to get clarification on its limitations.

Would it be common for magic users to recognize the Silence spell and know easy ways to counter its effects? For example, a wizard familiar with the spell might know to just run a short distance in any direction to leave its area of effect, and then continue casting spells. I understand that different types of characters will have different knowledge of spells, but Silence isn’t a high level spell and would seemingly be well known to many mid- and even low-level magic users.

The related question below might shed light on how a character would react to the Silence spell, because they might instead interpret the effect as being deafened.

Does a character know the effects of a spell when they are affected by it?

I have created a custom enemy, a golem desgined to investigate new forms of magic, and my players are about to face him.

Among several other stuff, this creature has two spells called high and low arithmetics. Upon failing a saving throw, this spell deals damage each turn to whoever ends their turn on a place lower or higher than the golem, respectively.

My question is, would a character, upon taking damage the first time, know what the conditions for taking the damage would be?

I’ve seen tweet but as far as I’m concerned, that only tells them that indeed, they are victim of a spell. Is there any way for a character to figuring out the rules of a spell? (not counting deducing them by trial and error, of course). I don’t think an arcana check (as is the common rule) would be suitable in this situation since this is a spell that none of them could have ever seen/heard of since it was made by this creature.
