Glossy in camera tracking  I am having some fun with camera-tracking in Blender.  That is my result so far:    My question is: how can I make this table reflect the ship?   Nodes are standard Blender's setup for motion tracking.  There is a plane on Backround layer, receiveing the shadow. I tried adding glossy shader to the plane. But then plane is reflecting surroundings (light and skybox) which is breaking the effect.   Good solution for me would be if plane could reflect only the ship, and be transparent to all the other, but I don't know how to approach this.  Do you know any trick that could help me out?
Andrew Price released a nice tutorial on how to nicely put 3D objects on top of a real image:   I have seen images, such as this:  which have 3D elements over images and have actual reflections from the object showing up on the wet asphalt.  How can this effect be achieved using render passes (or any other way)?  Here is another example (from ):
Linux command line. Move all files and directories in directory, except some files and directories Is there a way to create synchronization profiles for Google Chrome? For example I want to tag some of my browsers as "home browser"s and others as "work browser"s and I want:   my bookmarks to be synced with all browsers, my extensions to be synced only within browsers of the same type (home with home, work with work) I've got a repo that I contribute to within an Organization that I administer. I'm trying to add it to careers, but it won't allow it. Is this on purpose? I don't really want to fork it to my personal account, since I won't be maintaining it from there. What is a wave? C# Speech Recognition - Is this what the user said? I have need to write an application which uses a speech recognition engine -- either the built in vista one, or a third party one -- that can display a word or phrase, and recognise when the user reads it (or an approximation of it).  I also need to be able to switch quickly between languages, without changing the language of the operating system.  The users will be using the system for very short periods.  The application needs to work without the requirement of first training the recognition engine to the users' voices.  It would also be fantastic if this could work on Windows XP or lesser versions of Windows Vista.  Optionally, the system needs to be able to read information on the screen back to the user, in the user's selected language.  I can work around this specification using pre-recorded voice-overs, but the preferred method would be to use a text-to-speech engine.  Can anyone recommend something for me? How to prototype? How is prototyping done in a professional EE environment? Do you do your prototypes on breadboards, on copper clad boards, Manhattan style, or do you just draw schematics, order PCBs made and assembled and work with them, hacking here and there if necessary? I would like to close some view windows that I opened accidentally.  See the image below:    Edit: another note: I tried searching for the solution, but only found things like "Join Area", which don't seem to work in this situation. Would you please explain the difference between these two sentences?     Spain ceded (or gave) Puerto Rico to the United States. Since then, Puerto Rico has been a U.S. territory.

Evaluation of $\int_{0}^{1}\frac{x\ln (x)}{\sqrt{1-x^2}}dx$ Evaluation of $\displaystyle \int_{0}^{1}\frac{x\ln (x)}{\sqrt{1-x^2}}dx$   $\bf{My\; Try::}$ Let $\displaystyle I = \int_{0}^{1}\frac{x\ln x}{\sqrt{1-x^2}}dx\;,$ Put $x=\cos \phi\;,$ Then $dx = -\sin \phi d\phi$  and Changing Limit, We get  $$\displaystyle I = -\int_{\frac{\pi}{2}}^{0}\cos \phi \cdot \ln(\cos \phi )d\phi = \int_{0}^{\frac{\pi}{2}} \ln(\cos \phi)\cdot \cos \phi d\phi$$  Now Using Integration by parts, We get  $$\displaystyle I = \left[\ln(\cos \phi)\cdot \sin \phi\right]_{0}^{\frac{\pi}{2}}+\int_{0}^{\frac{\pi}{2}}\frac{\sin^2 \phi}{\cos \phi}d\phi$$  So $$\displaystyle I = \left[\ln(\cos \phi)\cdot \sin \phi\right]_{0}^{\frac{\pi}{2}}+\int_{0}^{\frac{\pi}{2}}\frac{(1-\cos^2 \phi)}{\cos \phi}d\phi$$  So $$\displaystyle I = \left[\ln(\cos \phi)\cdot \sin \phi\right]_{0}^{\frac{\pi}{2}}+\int_{0}^{\frac{\pi}{2}}\sec \phi d\phi-\int_{0}^{\frac{\pi}{2}}\cos \phi d\phi$$  So $$\displaystyle I = \left[\ln(\cos \phi)\cdot \sin \phi\right]_{0}^{\frac{\pi}{2}}+\left[\ln\left|\sec \phi+\tan \phi\right|\right]_{0}^{\frac{\pi}{2}}-\left[\sin \phi\right]_{0}^{\frac{\pi}{2}}$$  So $$\displaystyle I = \left[\ln(\cos \phi)\cdot \sin \phi\right]_{0}^{\frac{\pi}{2}}+\left[\ln\left|\sec \phi+\tan \phi\right|\right]_{0}^{\frac{\pi}{2}}-1$$  Now How can I solve after that, Help Required, Thanks Find the limit of $\frac{\log(n+1)}{\log(n)}$ where $n\rightarrow\infty$. Here $n$ is a natural number so I guess we can't use L'Hopital What happens with the appearance of the folder icons in dark mode of macOS Mojave Finder? In High Sierra I used some custom icons for my folders in the Finder; but with the new update to Mojave and the dark mode, the predefined icons also become darker. However the custom icons don't.  Inspecting an element you find a dark preview, but when you extract the icon this is the clear, the same as there was in High Sierra. E.g.:   Previously visualization of the developer predefined icon. It's dark:  But if you extract that icon, it's clear:    There are no dark icons in the system library, at least not in the same directory as always:  /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources   Are they being actively obscured by the operative system without there being icons with that real appearance? In this case, any idea to apply this method to the custom icons without modifying it into a new coloration? I have an Asus Sabertooth Z170 motherboard, with a Samsung 950 Pro m.2 NVMe drive on it. I've heard in the past that installing Windows 7 on an NVMe drive was a significant amount of work. Its now August 2016, is it still difficult? I've seen updates from Microsoft saying they've added support for NVMe in Windows 7.  Can I just download Windows 7 from Microsoft () and put it on a USB drive and install?  Is it harder than that? Where is "the" used? Is there a rule? Why no definite article in "Shops are open late in summer"? Notice these sentences:   Shops are open late in summer.   Summer is a traditionally viewed as a slow season for games.   At the summer solstice, the days are longest and the nights are shortest.   it's time to start thinking about what 2016's Song of the Summer will be.    In English class, they told us that "the" is used for the things that are known.  One example for this was a phrase like "The man who killed his wife".  So when we are speaking of that man, we know what he did. Somehow we know something more than nothing about him. He's not just every man in the world.     So Now I'm confused about why "the" is not used in the first and second sentences. Can anyone please explain it for me? Can a massless rope accelerate? How do I find out which paths my (La)TeX installation checks looking for packages (on a Linux system)? I know that I can check from where one particular package would be called, using  kpsewhich &lt;packagename&gt;.sty   and that if I want a custom package, I usually have to put it in the same folder as my document.   I assume that similar to a $PATH, LaTeX checks a list of paths in an attempt to find my package.   Which paths are those? In what order are they checked? If this is system-specific, how can I find out the configuration for my system?   Related questions:    , the answers to which contain some paths that  LaTeX apparently checks.  mentions    &gt;    /usr/local/texlive/2009/texmf &gt;    /usr/local/texlive/2009/texmf-dist &gt;    /usr/local/texlive/texmf-local &gt; &gt; as well as other directories.   (Neither of those lists is complete). Using Blender Game Engine for VR 360 tour on Mobile, is it doable? I'm sorry if my question sounds clumsy, I'm not a seasoned BGE user.  I'd like to make a virtual tour for Gear VR and/or Google Cardboard in the BGE that works on Mobile.  Is this doable in a user friendly way using the BGE? Can I export to Mobile (android, IOS, Windows Phone)? I know this is possible using Unity, but I find Unity difficult to use. I've tried UE4, but the process is a big mess, it requires a buggy multi-level hack that only results in wasting my time. In the movie Interstellar,  Cooper (played by ) enters a black hole and sends a message to Murph (his daughter). Later, he is found by rangers, but I don't understand how he gets out of the black hole?  As far as I know, nothing can get out of a black hole, as it has extremely high gravity.

What is the relationship between MIME types and File .extensions? I may have the wrong idea here, but I thought that:    MIME types are identifying codes, embedded inside a file. File .extensions are idenifying codes, suffixed to the file's name.   I thought, from something I heard in the dim dark ages, that Linux was .extension agnostic... ( maybe it was in the early days, and things have changed since then...? )  I've recently come from the Windows world, where, at the Operating-System level, a file .extension is the only way (as far as I know) to associate it with its relevant Application program.    Because I don't know why, I find it a bit disconcerting that a file named  "fred" and a file named "fred.txt" both open up in a Text Editor.    Is there a clear-cut hierarchy at work here? Is there a software utility to adjust screen gamma/brightness/contrast?
