A prominent instance is the fruit bowl in Berlinghoff Rasmussen's quarters in "".  The first thing that Rasmussen does when Data takes him to his guest quarters is take a piece of fruit and shove it in his pocket.  Who replicates fruit for these fruit bowls before guests arrive?  More generally, who removes unused fruit and tidies quarters after guests leave?  Is there a ship hospitality staff, perhaps including Guinan's wait staff in Ten Forward?

I tried  \usetikzlibrary{intersections} \begin{tikzpicture}[every node/.style={black,above right}] \draw[name path=line 1] (0,0) -- (2,2); \draw[name path=line 2] (2,0) -- (0,2); \fill[red,name intersections={of=line 1 and line 2}]     (intersection-1) circle (2pt) node {1}     (intersection-2) circle (2pt) node {2} \end{tikzpicture} Plot points:   I think the man was one-armed or had one damaged/withered arm. He is an artist when we meet him. He's picked up by aliens to represent earth in a galactic armada. Put in a ship with other aliens only there so a representative of their species can be said to be present - but not expected to actually contribute much to the coming fight. Fight is to protect against invaders from another galaxy. Somehow or other, their ship and crew become integral to winning the war. How to correctly add a path to PATH?

I'm trying to currently rename a large set of files and have been using quite kludgy methods to do so, such as:  rename 's:(.*)\.MOV:$1.mov:g' *.MOV rename 's:(.*)\.JPG:$1.jpg:g' *.JPG   What I'd really like to do is to be able to combine all of these commands using the . Evidently, using this operator, you can transform items to lower case. The problem is that I need to convert only the extensions. Is there a way to do this using this command? I need to essentially transform the capture group in the following expression to lowercase: ^.+\.(.+)$. Is there a way to do this? I'm kind of new to these kinds of transformations. I'm trying to install wifi drivers for a particular mini wifi card i bought. The output of lsusb is:  0bda:f179 Realtek Semiconductor Corp   I've searched everywhere for drivers, but could not find anything. Any help?  Thanks I am currently in hard mode and during a blood moon, several of my NPCs including my guide and my healer died. it's been several in game "days" now and they have yet to respawn. Is there a way to check why they aren't respawning?   Is there a list of reasons for the NPCs to not respawn?   Edit in reponse to lunbok's answer:  1. They don't have appropriate housing - There is an in-game housing query function (changes your cursor into a ?) that lets you click on your house to see if it is still a suitable house and I clicked in every room in my house and they are all listed as "This housing is suitable" or "This housing is already occupied".  2. Their spawn conditions aren't met anymore. - This doesn't explain why my guide isn't respawning since they don't need a condition to respawn (other than having a suitable housing which the point above already prove isn't the problem).  3. There's a goblin invasion going on. - Do the invasions last that long? It has been about two reals days and a lot more in-game "days" now. As far as I can tell there shouldn't be an invasion going on.  4.

Search and download audio-only from youtube Is there a way to search and then download from YouTube, with the situation that I only need to download the audio only, not the video. Extrusions causing problems in edit mode When I extruded vertices in edit mode, for some reason one of the sides of my 3-D model (the textured-looking side to the right) is creating a lot of errors. First off, it automatically sets extrusions on the x-axis. Secondly, it doesn't allow me to extrude planes into 3-D shapes. Thirdly, I can't increase the height of vertices without it creating a new face. Finally, it renders those automatic textures to create a grainy black texture in render mode. I attached an image with the solid object (top) and the rendered object (bottom). Note: I did not set any textures or alter the lighting on the model. Also, the left gray side is working perfectly fine without errors.
