What does it mean for a device to be hardwired?

Recently while reading about security cameras in Shadowrun 5e, I came across a forum post where someone suggested that if you don’t want a decker to be able to disable your security cameras, you can hardwire them. From what I understand this means that they are not connected to the matrix, but what is less clear is whether that’s all, which leads me to my question: What does it mean for a device to be hardwired in Shadowrun 5e?

What does the Wand of Wonder mean when it says “as if you had cast” vs. “you cast”?

One of the possible effects of the wand of wonder magic item is (emphasis mine):

You enlarge the target as if you had cast enlarge/reduce. If the target can’t be affected by the spell, or if you didn’t target a creature, you become the target.

There are multiple possible effects for the wand of wonder that use a similar wording. There are also many possible effects for the wand that say instead that "you cast [spell]".

Mechanically, what are the differences between the two wordings (if any)? What exact aspects of the spellcasting process/effects are different between the two?

What does it mean by the error “10 is not a valid variable”?

I wrote a very basic test function in Mathematica (I am the absolute beginner)

Fun1[x_] := Module[ {y, z, t}, y = Min[x + 10000, 500]; z = y + 24; t = y + z; t ] 

However, when I try to solve for the root Solve[Fun1[x] == 0, x], I was never able to get the expected value, but this error occurred "… Solve::ivar: 10 is not a valid variable".

what does it mean? and how to overcome this?

Many thanks Tien

What does it mean to become lost?

The DMG (p111-112) suggests that the party’s navigator make a Survival check to avoid becoming lost:

If the Wisdom (Survival) check succeeds, the party travels in the desired direction without becoming lost. If the check fails, the party inadvertently travels in the wrong direction and becomes “lost.” The party’s navigator can repeat the check after the party spends 1d6 hours trying to get back on course.

(emphasis mine, to clarify to those who are confused that going “in the wrong direction” and becoming “lost” are independent of one another)

So, as this reads, three distinctive things happen if you fail the check:

  1. You travel in a random direction.
  2. You become lost.
  3. You can make a new Survival check every 1d6 hours to stop being lost.

I completely understand points 1 and 3, but it doesn’t mean anything without understanding point 2. For example, let’s say I’m using the UA Ranger. I’m not able to become lost by nonmagical means, but since there doesn’t seem to be a RAW definition, that might mean any (or all) of the following:

  • You don’t travel in a random direction when you fail the check.
  • You don’t have to wait 1d6 hours to get back on track.
  • You have traveled in the right direction, but you don’t know where you are geographically.
  • You know exactly how to get from point A to point B, even if you don’t have a map and/or you’ve never been there.
  • You can’t trigger random Terrain Encounters (as in Chapter 2 of Out of the Abyss) because they suggest that you don’t know where you’re going.
  • Thick fog, rain, darkness, and other nonmagical elements can’t keep you from finding the path.
  • You don’t make a check at all, and you benefit from all of the above.
  • Maybe something else that I haven’t thought of.

Which of these options are true? Why? I will accept an answer that confirms and/or denies all of the assumptions listed above.

What does a kernel of size n,n^2 ,… mean?

So according to Wikipedia,

In the Notation of [Flum and Grohe (2006)], a ”parameterized problem” consists of a decision problem $ L\subseteq\Sigma^*$ and a function $ \kappa:\Sigma^*\to N$ , the parameterization. The ”parameter” of an instance $ x$ is the number $ \kappa(x)$ . A ”’kernelization”’ for a parameterized problem $ L$ is an algorithm that takes an instance $ x$ with parameter $ k$ and maps it in polynomial time to an instance $ y$ such that

  • $ x$ is in $ L$ if and only if $ y$ is in $ L$ and
  • the size of $ y$ is bounded by a computable function $ f$ in $ k$ . Note that in this notation, the bound on the size of $ y$ implies that the parameter of $ y$ is also bounded by a function in $ k$ .

The function $ f$ is often referred to as the size of the kernel. If $ f=k^{O(1)}$ , it is said that $ L$ admits a polynomial kernel. Similarly, for $ f={O(k)}$ , the problem admits linear kernel. ”’

Stupid question, but since the parameter can be anything can’t you just define the parameter to be really large and then you always have linear kernel?

What does “(any sword)” mean in terms of Magic Items?

In the Dungeon Master’s Guide section for Magic Items (Chapter 7), a lot of items have a requirement that says (any ___), specifically weapons and maybe armor if I remember correctly. For example, Flame Tongue says: “Weapon (any sword)”. Is this just to classify what the Item can be, or can you use another Magic Item in this place? Personally, I think a Vicious, Flame Tongue, Dragon Slayer, Vorpal Sword would be dope, but I’m not sure if that would work.

What does the ‘ (prime) mean in this context?

I’m trying to check a simple calculation regarding the derivative of a matrix exponential. By hand I get $ $ \frac{d}{d\theta_1}e^{\theta_1 \mathbf{W_1}+\theta_2\mathbf{W_2}} = \mathbf{W_1}e^{\theta_1 \mathbf{W_1}+\theta_2\mathbf{W_2}}. $ $ Checking this with Mathematica, I have

Assuming [{\[Theta]1 \[Element] Reals, {W1, W2} \[Element]     Matrices[{d, d}, Reals, Symmetric]},   D[MatrixExp[ (\[Theta]1 W1 + \[Theta]2 W2)], \[Theta]1]] 

which returns

(* W1 Derivative[1][MatrixExp][W1 \[Theta]1 + W2 \[Theta]2] *) 

Why is there a derivatie here? And what’s the [1]?

What Does Twitter’s s Parameter Mean?

When I use the share button on Twitter the link becomes https://twitter.com/username/status/ID?s=number instead of https://twitter.com/username/status/ID. What is the meaning of this ‘s’ parameter? Is it an ID that gets generated to see who uses the link you shared? I’m assuming the ‘s’ stands for share ID or <joke>spy on you</joke>. The link works the same without the ‘s’ parameter.

Am I right about this or is it something else?

What do the symbols in the header of Hunter-Net Mean?

Hunter-Net is the messageboard/list serv archive that the Imbued use in Hunter: The Reckoning. The header to the site looks like this:

enter image description here

What do the symbols (hunter code) in the header mean? The symbol on the right means "hope", but I can’t find the symbol on the left in any of the dozen or so Hunter books I own. It also doesn’t appear on the WhiteWolf fan wiki.

So what does it mean?

What does Carpenter169’s prophecy mean?

In The Walking Dead, a book for Hunter: The Reckoning, the character Carpenter169 delivers a prophecy on hunter-net:

The hour of flame comes and the Emperor of Hell manifests. The twin-souled children of Jade have risen from their graves and await the hour that will sweep away those whose souls are not divided. The storm heralds the hour of destruction and its winds shall fan the flames even higher. Heaven’s step children wander, blind into the kingdom of death, but their sight is keen. Rotten blood and rotten souls gather under the horns of blood. Fire shall not cleanse us, and our bones will be as sand."

I think I recognize a few isolated pieces here. For example, I’m pretty sure that the storm mentioned is the 6th Great Maelstrom. There is so much happening here that I can’t figure out where to start my reading to decypher the rest. The "Emperor of Hell" sounds like something from Demon, or maybe Wraith, or maybe Kingdoms of the East…. you get the picture.

What’s this prophecy talking about?

An ideal answer would answer holistically (the big picture of the prophecy and how it fits into the World of Darkness), but also explain the individual references ("Emperor of Hell", "children of Jade", etc.).
