Glossy reflecting only one object
How to get reflections from 3D to show up on real images
Why does latex stretch small sections across the whole page vertically? I'm writing my bachelor-thesis and have a couple of small sub-sub-sections explaining conversions, like in the following  \subsubsection*{Assignment}  This document only explains non-compound assignments. The other kind, i.e \texttt{a += b}, is supported by the language too, but is not yet implemented.   \begin{itemize} \item If the first is an \texttt{auto} variable, no conversion takes place when assigning       the right hand side to the variable designated by the left hand side.  \item Otherwise, an assignment conversion takes place converting the given value to the type       of the designated variable.  \item Assignment requires an lvalue as the left hand side, and yields an lvalue result.  \end{itemize}  \subsubsection*{Multiplication} % ...   But latex renders it quite ugly with much space in between the items. I think it does so to fit the whole page. How can I tell it not to do so? Is what I'm doing right at all? I have just finished my homework.   I just finished my homework.      I think there must be a difference in meaning. Could anyone tell me the difference in meaning sentence 1 and sentence 2? I write financial applications where I constantly battle the decision to use a double vs using a decimal.  All of my math works on numbers with no more than 5 decimal places and are not larger than ~100,000. I have a feeling that all of these can be represented as doubles anyways without rounding error, but have never been sure.  I would go ahead and make the switch from decimals to doubles for the obvious speed advantage, except that at the end of the day, I still use the ToString method to transmit prices to exchanges, and need to make sure it always outputs the number I expect. (89.99 instead of 89.99000000001)  Questions:   Is the speed advantage really as large as naive tests suggest? (~100 times) Is there a way to guarantee the output from ToString to be what I want? Is this assured by the fact that my number is always representable?   UPDATE: I have to process ~ 10 billion price updates before my app can run, and I have implemented with decimal right now for the obvious protective reasons, but it takes ~3 hours just to turn on, doubles would dramatically reduce my turn on time. Is there a safe way to do it with doubles? How do I interpret the results of a regression which involves interaction terms? If I have a linear regression of the form:  $$y \sim 1+\beta_1x_1 + \beta_2x_1x_2,$$  where $x_2$ is a Boolean variable depending on another variable $x_{2cont}$, a positive variable:  $$x_2 = \begin{cases} 1 &amp; \mbox{if } x_{2cont} &gt; 5 \\ 0 &amp; \mbox{if } 0 &lt; x_{2cont} \le 5. \end{cases}$$  And I got regression results. How shall I interpret the regression results?  esp. how shall I interpret the two coefficients I get from this regression,  $\beta_1 \text{ and } \beta_2$? I've been watching a lot of pro replays ever since the SC2 beta came out, and I've noticed that almost always, when Protoss research upgrades, the shields are the last research chosen. Why is that? Seems to me that if anything, shields should be the most important upgrade, as they affect all Protoss units and buildings. Why can't I log into minecraft with a mojang account? I created a Mojang account and downloaded the Minecraft launcher, but when I started it up, I couldn't log in. Since the log in fields did not require a username, I tried typing in my email, and still couldn't log in. I've tried after resetting my password, but that didn't work either. What am I supposed to do to log in and play? How can i render the reflections i see in the Look Dev viewport in Blender 2.8 i'm finding blender 2.8 confusing and i'm relatively new to blender in general anyway. While looking at my model in the Look Dev view port i can see reflections.        However, when i render my scene in eevee (and cycles), the reflections aren't rendered     Is there something i'm doing wrong or an option i haven't enabled? Waiting for user input with a timeout I have searched but apparently my google foo is weak. What I need is a way to prompt for user input in the console and have the request time out after a period of time and continue executing the script if no input comes in. As near as I can tell, Read-Host does not provide this functionality. Neither does $host.UI.PromptForChoice() nor does $host.UI.RawUI.ReadKey(). Thanks in advance for any pointers.  EDIT: Much thanks to Lars Truijens for finding the answer. I have taken the code that he pointed out and encapsulated it into a function. Note that the way that I have implemented it means there could be up to one second of delay between when the user hits a key and when script execution continues.  function Pause-Host {     param(             $Delay = 1          )     $counter = 0;     While(!$host.UI.RawUI.KeyAvailable -and ($counter++ -lt $Delay))     {         [Threading.Thread]::Sleep(1000)     } } PHPExcel Sumif and Skip How can I dynamically invoke a class method in PHP? The class method is not static. It appears that   call_user_func(...)   only works with static functions?  Thanks. What is the differance between Linked and Appended data from external .blend files? Basic question, how do I resume interrupted / failed downloads in Firefox? iPhone 5S, LTE does not work How to embed a text file in a .NET assembly? I would like to embed a text file in an assembly so that I can load the text without having to read it from disk, and so that everything I need is contained within the exe. (So that it's more portable)  Is there a way to do this?  I assume something with the resource files?  And if you can, how do you do it and how do you programaticaly load the text into a string? Is the cube root of a prime number rational? I think this is just something I've grown used to but can't remember any proof.  When differentiating and integrating with trigonometric functions, we require angles to be taken in radians. Why does it work then and only then? How can I make Ubuntu 18.04 / 18.10 desktop use Unity (be like Ubuntu 14.04)? Can you grapple/shove with the Hunter Ranger's Whirlwind Attack? Where to get school zone shapefiles? Census.gov usually makes available the shapefiles containing school zone boundaries. Due to the US government shutdown, census.gov is down. Does anyone know where to download a recently archived copy? Why is there no overload of Interlocked.Add that accepts Doubles as parameters?
