I am trying to do a new environment or command (i tried both) where i can put in the name, description and code of a Method in c++ and it gives me a new section with the MethodName, the code listed and the description below. But i am not able to use the listings environment in a new command or new environment..

I would prefer to do it using a macro since I don't need an ending.
Replacing the core of a solenoid to increase the pulling force What are reaching fouls in the NBA? When a player tries to steal the ball from a dribbling player, the referees sometimes award a "reaching foul". I just can't see any difference between a steal and a foul Bump and color data in a single brush? Is there any way to paint onto a bump map and diffuse map at the same time, so that the strokes match up? Like a multi-layer brush that uses a greyscale texture for the bump layer and a color texture for the diffuse color?  Here's a rough sculpt to demonstrate what I'm imagining:    The GIF above shows how such a brush could be made. The black and white height map would be the displacement brush, transferring its greyscale data to the bump map texture and the green one would transfer its color data to the diffuse map texture.  The resulting brush images:      Making the brush is one thing, but is it possible to use such a brush? From a previous question, we have that $\sqrt[3]{3} \notin \mathbb{Q}(\sqrt[4]{3})$, and I am assuming that we would need to use this to justify the answer to the question.   Would it be right to use some idea of a splitting field here? Or is it something to do with $\mathbb{Q}(\sqrt[3]{3}, \sqrt[4]{3})$ not containing a primitive 3rd root of unity?   This is a past exam paper question worth 8 marks, so it doesn't seem like it's a few lined answer, but I am a little stuck on where to go. Can I use a present-tense verb when writing about a past event? Does the stock market create any sort of value? Sorry if the below seems like a conspiracy theory. It probably is, but I probably don't understand something. (This has bugged me to no end as long as I can remember.)  Okay, so here is what I understand about the stock market?   The main way money enters the stock market is through investors investing and taking money out. The only other cash flow is in through dividends and out when businesses go public.   In a Ponzi scheme, there is usually some small source of income to hide the fact that it's a Ponzi scheme. Dividends are pretty insignificant. For the purposes of this question, we will only consider non-dividend stocks.  When you buy stock, it is claimed that you own a small portion of the company. This statement has no backing, as you cannot exchange your stock for the company's assets.   For example, if I bought $10 of Apple Stock early on, but it later went up to $399, I can't go to Apple and say "I own $399 of you, here you go it back, give me an iPhone." The only way to redeem this is to sell the stock to another investor (like a Ponzi Scheme.)  The stock market goes up only when more people invest in it. Although the stock market keeps tabs on Businesses, the profits of Businesses do not actually flow into the Stock Market.   In particular, if no one puts money in the stock market, it doesn't matter how good the businesses do.    Based on the above, it seems like the Stock Market has little to do with investing businesses to create growth, and primarily grows in a similar way to a Ponzi Scheme. (Some differences include that it is Stochastic (so when it collapses, it can be blamed on luck or the economy) and it has no top operator (similar to a Pyramid Scheme)).  Am I missing something? Does the stock market create value for investors? Jquery validation not working with ckeditor How do I match any character across multiple lines in a regular expression?

Therefore, as space expands the energy in the universe that comes from dark energy would increase. I presumed the source of this energy was not coming from the conversion of other types of energy to dark energy, so it must violate conservation.  I decided to Google this and came upon this article:    It says that dark energy does NOT violate conservation and quotes Carroll, Press, and Turner (1992):  "…the patch does negative work on its surroundings, because it has negative pressure. Assuming the patch expands adiabatically [i.e. without loss or gain of heat], one may equate this negative work to the increase of mass/energy of the patch. One thereby recovers the correct equation of state for dark energy: P = – ρ c2. So the mathematics is consistent."  Is there a way to explain this in layman's terms? (The blog attempted to do this, but it was very unclear to me.) More specifically, can you explain where my initial train of thought described above fails when I erroneously concluded that dark energy violates conservation?  Thank you. If I could stop ALL motion would I stop time? I've never really understood time. Time is not a force. It isn't energy or matter. Time doesn't MAKE anything do anything. Time doesn't make a clock tick (motion or batteries do). Time doesn't make the earth revolve around the sun (motion/gravity does). I don't think time exists. People say time is used as a form of measurement but aren't we just measuring movement? Even atomic clocks measure the movement of electrons that orbit an atom's nucleus as they "jump" back and forth between energy states. So my question is if I were to stop ALL motion (even movement of electrons that orbit an atom's nucleus) would I stop time? Is time just masquerading as the measurement of motion?  EDIT: This question is not a duplicate of "Does time freeze at Absolute Zero?" Because I am NOT talking about temperature. I am speaking about the motion of ALL things. I am asking if ALL things (photons, energy, matter, forces) stop moving would time stand still? I would have to say yes it would. If ALL motion were to stop for a million years and then start again no one would even know. Atomic clocks wouldn't even miss a step. What is the cause of this sudden drop in CV queue size? How do I tell which point-and-shoot cameras take good low light photos? I have a Canon Powershot A710 and I previously had a previous Powershot A-series model. I love them due to the high amount of control they offer. Sadly, they both suck in low light conditions, their flash is very unresponsive, and the camera takes several seconds preparing itself for the next shot after a flash shot. And even then, the pictures they take in low light/flash are as bad as good are those with good light.  I'd like a camera which gives a lot of control options, but what do I need to look for to find one that's great in low light, with or without flash? extending convergence radius using one boundary point Show that if $f(z)=\sum\limits_{n\geq0}a_nz^n$ is analytic in $\{z\in\mathbb{C}:|z|&lt;1\}\cup\{1\}$ and $\forall n\geq0:a_n\geq0$ then the radius of convergence of the power series is strictly larger than $1$.  My approach:   Let $D=\{z\in\mathbb{C}:|z|\leq1\}$.  We have that $f(1)$ converges, so $\sum\limits_{n\geq 0} a_n&lt;\infty$. Moreover since the $a_n$'s are all positive we have that $|a_n|=a_n$, therefore $\sum\limits_{n\geq 0} |a_n|=\sum\limits_{n\geq 0} a_n&lt;\infty$.  Let $f_n(z)=a_nz^n$, then $\forall z\in D, n\geq 0$ we have:  $$|f_n(z)|=|a_nz^n|=|a_n|\cdot|z^n|=a_n\cdot |z|^n\leq a_n\cdot 1^n\leq a_n$$  Then, applying Weierstrass M-test we get that the power series is convergent in $D$.  Now, I need to "find" an open ball $B$ such that $D\subset B$ and the power series is convergent in it.  Edit  $f$ is analytic in $1$, so there is an open set $U$ that contains $1$ such that   $$f(z)=\sum\limits_{n\geq 0} b_n(z-1)^n$$  Does it mean that the series is convergent in $U$?   I can see that we have that the two series coincide in $D\cap U$. Understanding English (Listening skills) Can someone point me to a proof that the set of irrational numbers is uncountable? I know how to show that the set $\mathbb{Q}$ of rational numbers is countable, but how would you show that the irrationals are uncountable? Do multi-use keys get discarded when finished with? As with many resident evil games, you sometimes needs to collect certain keys to open certain doors, and resident evil 7 has plenty of these around.  Some keys are clearly single use, and get left in the lock in which you use them. However, there are a number of keys that can be used on multiple doors. For example, the Scorpion Key.  I am concerned that I might end up carrying these around needlessly and using up valuable inventory space, so...  Do these multi-use keys get discarded when you use them on all the doors they apply to? Or do you get a warning saying the key is no longer needed?
