A previous question "" suggests that a Druid could use a summoned animal as a mount.  However, how might this work in combat?  Would the conjured animal act and be controlled like any other mount?    Furthermore, could a conjured animal act as a mount for another party member?  Per the spell (emphasis mine):     The summoned creatures are friendly to you and your companions. Roll   initiative for the summoned creatures as a group, which has its own   turns. They obey any verbal commands that you issue to them (no action   required by you). If you don't issue any commands to them, they defend   themselves from hostile creatures, but otherwise take no actions.   Could the summoned animal be controlled as a mount by the other party member?  What if the druid commanded the conjured animal to obey the commands of the other party member, or ask as a mount?  Do summoned fey spirits act like the animals form they take?
Is it possible to use the animals that are summoned using Conjure Animals as mounts?  As an example: Summoning Giant Eagles to carry a group up the mountain or over a wall.
How secure is Activation Lock on iOS 7 (and later)? Apple showed this new feature in iOS 7 called Activation Lock, that if you enable "Find My iPhone" on a device that is lost or stolen, a person that finds/gets the iPhone will not be able to wipe it or reset it. I'm curious whether the lock is designed to prevent these avenues to defeat the lock:   Can they completely drain the battery and leave the phone in that state for a couple of months and then try it? Or, can they use any third-party software that can access iPhone from outside the iTunes and wipe it that way? Or, can they simply "jailbreak" it and forget about this Activation Lock?   By what methods can this lock be defeated or bypassed? In C, is it possible to forward the invocation of a variadic function? As in,  int my_printf(char *fmt, ...) {     fprintf(stderr, "Calling printf with fmt %s", fmt);     return SOMEHOW_INVOKE_LIBC_PRINTF; }   Forwarding the invocation in the manner above obviously isn't strictly necessary in this case (since you could log invocations in other ways, or use vfprintf), but the codebase I'm working on requires the wrapper to do some actual work, and doesn't have (and can't have added) a helper function akin to vfprintf.  [Update: there seems to be some confusion based on the answers that have been supplied so far. To phrase the question another way: in general, can you wrap some arbitrary variadic function without modifying that function's definition.] Why is propagation of uncertainties quadratic rather than linear? I'm a little confused about the following sentences. Could you please tell me which one(s) is/are correct?        The first and the second chapter are difficult.   The first and the second chapters are difficult.   The first and second chapters are difficult.   The first and second chapter are difficult.      I believe #1 &amp; #3 are correct, while #2 &amp; #4 are incorrect.  But when seeing the answers to the Quora question , I wonder why they say #2 is correct. How can I find the points at which two circles intersect? Given the radius and $x,y$ coordinates of the center point of two circles how can I calculate their points of intersection if they have any? How does the new Tie-Breaker work? In Clash of Clans there was an update on 9/16 adding a Tie-breaker into the wars, can anybody explain in detail how this mechanism works? Finding the derivative of $x\uparrow\uparrow n$ I am trying to find a general derivative for the function: $f(x)=x^{x^{x^{...^{x}}}}$however to do that I must find $f^{\prime }$ and $f^{\prime \prime}$...etc. I am now trying to write down a general expression for $f^{\prime \prime}$ and I have stumble opon the series in the picture below, I wonder, do anyone have an idea of what sort of expantion it migth be ? I have tried breaking it down into three different sums, but I wasn't very successful!  EDIT  So since this post has gotten some attention and the title has been change I will tell you what I am on about, although I already have a post just for the question in the title from before. I am as I said earlier trying to find a general derivative for the function $f(x)=x^{x^{x^{...^{x}}}}$ where $n$ is an arbitrary number, natural number and greater or equal to 2. I have already made success when I tried to find the first derivative, and I have also found some interesting pattern emerge when the derivatives as well as n incresses. But my question here was if anyone knew what this expation might be or look similar to be, since I have yet to be lernt series etc. I did not know that the question needed such background since it's straight a forward question. How can I stream the same music to multiple computers? Is there a way to stream the same playlist on multiple computers at the same time? I want to be able to sync what's playing on multiple computers (for parties etc). With \setbeamercovered{transparent} covered parts of a slide are displayed transparently. If there is a (small) picture among the text, it is shown as it is. Beamer has only this picture, so it shows this picture. My question: How can I give a gray version of the picture to beamer such that in covered parts of a slide, this gray version is used? Why doesn't matter pass through other matter if atoms are 99.999% empty space? The ghostly passage of one body through another is obviously out of the question if the continuum assumption were valid, but we know that at the micro, nano, pico levels (and beyond) this is not even remotely the case. My understanding is that the volume of the average atom actually occupied by matter is a vanishingly small fraction of the atom's volume as a whole. If this is the case, why can't matter simply pass through other matter? Are the atom's electrons so nearly omnipresent that they can simultaneously prevent collisions/intersections from all possible directions? I noticed there is a square knob sticking out of my basement wall. Does anyone know what this is? $1 \leq z \overline {z} \leq 4$ and $|\Im(z)|&lt;\Re (z)$  How can I solve this system of inequalities? ($\Im$ is the imaginary part and $\Re$ is the real part of a complex number).  I have tried so far: $z=x+yi$ and then I get $1 \leq x^2+y^2 \leq 4$ and $ |y|&lt;x$. How can I solve this? How can I check dependency list for a deb package How can I check dependency list for a deb package. I am running Ubuntu 11.10 and I have backed up all deb packages from var/cache/apt/archives. I want to format my pc and re-install selected applications only. Also how can I get the list of installed packages and dependencies. If the $n^{th}$ partial sum of a series $\sum a_n$ is $S_n = \frac{n-1}{n+1}$, find $a_n$ and the sum. "Whether" Vs. "If" Mouse cursor doesn't change to pointer when hovering "full site" on mobile When (accidentally) clicking "mobile" in the footer, one gets the mobile site in a regular browser too. To switch back, one can click "full site" in that same footer:    However: when hovering it, the mouse is changed as to select text, rather than to indicate one can click (even though it's clickable).  All other links do change the mouse into a pointer.  (Not a big deal, except when somehow  getting into the mobile mode, I guess.) How do I configure swappiness? I need a step-by-step, simple and easy way to configure swappiness. $A$ is a $n\times n$ matrix such that $ A^m = 0 $ for some positive integer $m$.   Show that $A^n = 0$.   My attempt: For $n &gt; m$, it's obvious since matrix multiplication is associative.  For $n &lt; m$, $A^n\times A^{m-n} = 0$; not sure what to do next. Also I know that $\det A = 0$. Is a black hole singularity a single point? General relativity is expressed in terms of differential geometry, which allows you to do interesting things with the coordinates: multiple coordinates may refer to a single point, eg. the  has whole lines at the top and the bottom that correspond to the North and South poles, respectively; or a single coordinate may refer to multiple points, for example by using inverse geometry the origin refers to all the points infinitely far away.  So, is the singularity just a single point in the curved spacetime, or can it be a more extended object, described by a single coordinate? RegEx: Grabbing values between quotation marks I have a value like this:  "Foo Bar" "Another Value" something else   What regex will return the values enclosed in the quotation marks (e.g. Foo Bar and Another Value)?
