Far as I can tell eevee will always render any shape with a volumetric material applied as a cube or rectangle, as opposed to say a sphere or something a bit more complex. Is this a hard limitation? Or something that might change later.
So I was in the middle of making a ball-shaped smoke, but the volumetric effect didn't work following the basic shape. It remains cube in Eevee Blender 2.8; while in Cycle it works, but in Cycle it takes thousands of years for Render.
One way function existence Let $x = (x_1, x_2,...,x_n)\in\{0,1\}^n$ for $n\in\mathbb{N}$. Prove that if one-way functions (OWFs) exist, then there exists a one-way function $f$ such that for every bit $i\in[1,n]$ there exists an algorithm $A_i$ such that: $$\Pr[A_i(f(x)) = x_i] \geq \frac{1}{2} + \frac{1}{2n}$$ I'm having trouble understanding this. How to give a medicine with really bad taste My 4 year old daughter recently have scarlet fever. It seems antibiotics are non-negociable for it, and since she has great chance of being allergic to Penicillin, there is only one antibiotic she can get. It is not the first time we have to give it to her, and probably not the last time.  Apparently, that medicine tastes really REALLY bad. She cries a lot, panics every time we say it's time for this medicine, and vomit it most of the time, resulting in even more medicine being force into her mouth.  It is only this medicine that causes problem. She does not tantrum for other medicine, and most of them, she can take the dose we give her all by herself.  We tried reassuring her, explaining why it is mandatory to get it, explaining it will make the scarlet fever go away. We tried mixing it into other food (which seems clearly worse, taste-wise). We tried asking her to take her herself. It seems we tried everything, and the only thing that achieve it for the moment is actually forcing it into her.  We really do not want to force her in any way. Her mother cried yesterday because we had to force her, and we need to do it twice a day. It is very exhausting, and we would welcome any input or new ideas on how to give her this really bad tasting medicine to her.  EDIT : For clarification, it is a liquid medicine that is administrated with a syringe. It seems there are no alternative, although we will check with the doctor again (particularly if pills are available) Why do we say the following?        I'll have an hour's wait at the airport      Today's lesson      Yesterday's programme    Two weeks' worth of groceries.      They are not possessive, or are they? Why is the possessive apostrophe used with time expressions and adverbs? I want to resize the Unity launcher. Is that possible? Prove $ \sum \frac{\cos n} { \sqrt n}$ converges River flowing down a slope I have a Dedicated Bedrock Server running on my PC, and I can't connect from the same PC where the server is. If I add it onto the list of servers, it appears as "Locating server" and never finds it.    If I try to connect, I get "Unable to connect to world".    On my friend's PS4, it appears on the Friends tab as a LAN Game on a Dedicated Server.    And also on my sister's laptop. Why do we use GLM? Integral $\int_{\frac{1}{2}}^1 \frac{\ln x}{\sqrt{x^2+1}}dx$ How is it, that $\sqrt{x^2}$ is not $ x$, but $|x|$? As far as I see, $\sqrt{x^2}$ is not $x$, but $|x|$, meaning the "absolute". I totally get this, because $x^2$ is positive, if $x$ is negative, so $\sqrt{y}$, whether $y = 10^2$ or $y = -10^2$: $y$ is positive.  But then I remember that $\sqrt(x)$ is the same as $x^{1/2}$ and thus, $\sqrt{x^2}$ is the same as $x^{1}$.   So, as far as I get it, $\sqrt{x^2} = x^{2/2}$.  But then, I can cancel $\frac{2}{2}$ to $1$. So: $\sqrt{x^2} = x^1 = x$.  Where does the absolute value in this derivation of the calculation come from?  I get it why its there: Because $(-x)^2 = x^2$, so the radicand is always positive. But from $\sqrt{x^n} = x^{n/2}$ I dont understand how it gets there. Niven’s theorem proof. I couldn’t find any proof on the internet. I would appreciate an elementary proof , but any help would be appreciated!  Thank you. Given a ring $R$ (with unity), prove that if $a \in R$ is nilpotent, then $a+1,a-1$ are both invertible.   Suppose $a^n=0$. Then $1=1-a^n=(1-a)(1+a+\ldots+a^{n-1})$, so $1-a$ is invertible.  If $n$ is odd we can use $1+a^n=(1+a)(1-a+\ldots+a^{n-1})$.  But what if $n$ is even? Why do shadows from the sun join each other when near enough? I was laying on my bed, reading a book when the sun shone through the windows on my left. I happened to look at the wall on my right and noticed this very strange effect. The shadow of my elbow, when near the pages of the book, joined up with the shadow of the book even though I wasn't physically touching it.   I have posted :The video seems to be the wrong way up, but you still get the idea of what is happening.  What is causing this? Some sort of optical illusion where the light gets bent?  Coincidentally, I have been wondering about a similar effect recently where if you focus your eye on a nearby object, say, your finger, objects behind it in the distance seem to get curved/distorted around the edge of your finger. It seems awfully related...  EDIT: I could see the bulge with my bare eyes to the same extent as in the video! The room was well light and the wall was indeed quite bright. What is the sponsored party called? Google results for sponsee have scattered definitions in unreliable sources, so it does not appear that is a real word. I'm looking for something similar, a single word.  The specific context is a social group membership application where new members must be sponsored (as in definition 2, here - "one who assumes responsibility for some other person or thing") by existing members. I am looking for a single word to describe the target of such a sponsorship. I am about to sponsor a fraternity, but I would like to have a more general word for what I'm sponsoring. Next time, the fraternity could well be a study club, or something else.  Therefore, what is the sponsored party also called? E.g. if I sponsor somebody, that person is my __? Arduino only works in root I've installed Arduino but as the title says, I can only upload with sudo. And yes my user is part of the dialout group so that's the weird thing.   Arduino did function before on my system. What could be wrong?

The biggest issue is mana curve, of course. What shortcuts are best for determining the proper amount of land with a given mana curve? How to intuitively understand eigenvalue and eigenvector?
