Can Create Bonfire be placed in a way that affects multiple squares? The Create Bonfire cantrip creates a bonfire which "fills a 5 foot cube". It deals comparable damage to other cantrips, making one assume it's meant to only deal it (reliably) to a single target. But, if playing on a grid, is there something actually preventing a character from making the 5 foot cube be placed at an intersection, possibly damaging four creatures?
What space does the spell Cloud of Daggers fill? I am trying to workout what template  (PHB, p. 222) would be on a grid. The spell states:     You fill the air with spinning daggers in a cube 5 feet on each side, centered on a point you choose within range.   So does that mean it would look like this:     Or like this:    From what I've read online, there seems to be some suggestion that it is a single square (tile) though this does stack with the spell description of "a cube 5 feet on each side".  Clearing this up for my group would be great, and I am sure our DM will be pleased as his monster were nicely diced by this spell. Thanks.
Identify a movie in which aliens believed a sci-fi TV show to be true documentary I remember watching a sci-fi movie in the early 00s. It was full of comedy. Here are the details I recalled:   There was a space opera TV show in the movie. It seemed a true copy of Star Trek (they used to pilot a ship and there were captain, first officer, science officer etc on bridge). The name of the TV show was possibly the name of the movie. Once the main crew of the TV show were celebrating some achievement, they were approached by humans having weird behavior (they were actually aliens in disguise; in reality, they looked like octopus). The alien race was innocent. They couldn't comprehend the concept of art, lies etc. So, they believed that the TV show (they got the EM waves) was true historical documentary of mankind. So, they came looking for help from the brave captain of the show. From the TV show details, they had built a starship which really worked. The aliens needed the TV show crew to pilot the ship to defeat another alien race which terrorized them. The TV show crew didn't have any problems piloting the ship as the controls were familiar, only these controls were real.   Can you please identify the movie? Python mechanize javascript Change the Fill Color of a cell if the value of that cell equals the value of another specific cell I want to change the fill color of cell C5 if it has the same value as cell A5.   Can this be done? I know how to format cell C5 if it has a certain value - but not when it is to be compared to the value of another cell. Do Arcane Ward's starting hit points include the INT modifier once or twice? An abjuration wizard's Arcane Ward states:     [...] The ward has hit points equal to twice your wizard level + your Intelligence modifier.   So how many hit points is this supposed to be?  \$ (2 \times WizardLevel) + INT_{mod}\$  or  \$2 \times (WizardLevel + INT_{mod})\$ ?  I feel like the phrasing hints toward the first calculation, but it's still somewhat ambiguous. I was reviewing the  recently, and it occurred to me that one could allow for only scalar multiplication by the integers and still satisfy all of the requirements of a vector space.   Take for example the set of all ordered pairs of integers. Allow for scalar multiplication over the integers and componentwise vector addition as usual. It seems to me that this is a perfectly well-defined vector space.  The integers do not form a , which begs the question: Is there any reason that the "field" over which a vector space is defined must be a mathematical Field? If so, what is wrong with the vector field I attempted to define above? If not, what are the requirements for the scalars? (For instance, do they have to be a  - Abelian or otherwise?) Can I publish without affiliation? Problem with patching babel package I am trying to use babel and biblatex package together but I am getting following error:    !

I have a csv file that is 133mb in size and has over 1.3 million lines of data.  Each line of data has its own lat/long and I was wondering what would be the best way to display those points based off the lat/longs in ArcGIS Desktop 10 and ultimately turn it into a point shapefile?  So far I have tried the "Make XY Event Layer" tool but that keeps failing...  ERROR 000212: Cannot create XY event source Failed to execute (MakeXYEventLayer).  The csv file is properly formatted and the lat/long fields are numeric so I have no idea why it keeps crashing.  Here is what the first 2 lines of my CSV look like, the first line is what should be the header:  "LAT","LONG","CUSTOMER_MASTER_ID","STORE_NBR","TRANSACTION_DT","SKU_DIVISION_ID","SKU_DEPARTMENT_ID","SKU_CLASS_ID","SKU_CATEGORY_ID","SKU_NBR","SALES_AMT" "32.363544","-110.969778","2000000792627","2940","8/11/2010","2060","3920","5120","84021","5127866","13.99"   Any ideas? How to solve configure: error: readline library not found? I have an Ubuntu 10.04 LTS server with a minimal install that I want to compile postgres on. With the minimal install the server did not have gcc so I had to do an apt-get install gcc but now I keep getting this error from the postgres ./configure.  configure: error: readline library not found   I can't seem to find the name of the package that contains the readline library. So I have two questions.   What is the name of the package that contains readline? Is there some way given the error message above for me to find the associated package from its standard name? This question is a sequel of sorts to my  about .  In the paper, the authors performed molecular dynamics (MD) simulations of parallel-plate supercapacitors, in which liquid resides between the parallel-plate electrodes.  The system has a "slab" geometry, so the authors are only interested in variations of the liquid structure along the $z$ direction.  In my previous question, I asked about how particle number density is computed.  In this question, I would like to ask about how the electric potential is computed, given the charge density distribution.  Recall that in CGS (Gaussian) units, the Poisson equation is   $$\nabla^2 \Phi = -4\pi \rho$$  where $\Phi$ is the electric potential and $\rho$ is the charge density.  So the charge density $\rho$ is proportional to the Laplacian of the potential.  Now suppose I want to find the potential $\Phi(z)$ along $z$, by integrating the Poisson equation.  How can I do this?  In the paper, on page 254, the authors write down the average charge density $\bar{\rho}_{\alpha}(z)$ at $z$:  $$\bar{\rho}_{\alpha}(z) = A_0^{-1} \int_{-x_0}^{x_0} \int_{-y_0}^{y_0} dx^{\prime} \; dy^{\prime} \; \rho_{\alpha}(x^{\prime}, y^{\prime}, z)$$  where $\rho_{\alpha}(x, y, z)$ is the local charge density arising from the atomic charge distribution of ionic species $\alpha$, $\bar{\rho}_{\alpha}(z)$ is the average charge density at $z$ obtained by averaging $\rho_{\alpha}(x, y, z)$ over $x$ and $y$, and $\sum_{\alpha}$ denotes sum over ionic species.  The authors then integrate the Poisson equation to obtain $\Phi(z)$:  $$\Phi(z) = -4\pi \sum_{\alpha} \int_{-z_0}^z (z - z^{\prime}) \bar{\rho}_{\alpha}(z^{\prime}) \; dz^{\prime} \; \; \; \; \textbf{(eq. 2)}$$  My question is, how do I "integrate the Poisson equation" to obtain equation (2)?  How do I go from  $\nabla^2 \Phi = -4\pi \rho$ to equation (2)?  In paricular, where does the $(z - z^{\prime})$ factor come from?   Thanks for your time. Is it possible to have connecting loop lines (like algorithm2e) in algorithmic? I am using the algorithmic package to typeset an algorithm. I would like to have connecting lines between the beginning and end of a loop or conditional like in the algorithm2e package. Is there an easy way to accomplish this, or am I better off switching to algorithm2e? What is the fastest way to create a list of directories specified in a file? I have a text file, "foo.txt", that specifies a directory in each line:  data/bar/foo data/bar/foo/chum data/bar/chum/foo ...   There could be millions of directories and subdirectories What is the quickest way to create all the directories in bulk, using a terminal command ?  By quickest, I mean quickest to create all the directories. Since there are millions of directories there are many write operations.   I am using ubuntu 12.04.  EDIT: Keep in mind, the list may not fit in memory, since there are MILLIONS of lines, each representing a directory.

Proving : $ \bigl(1+\frac{1}{n+1}\bigr)^{n+1} \gt (1+\frac{1}{n})^{n} $ How could we prove that this inequality holds      $$ \left(1+\frac{1}{n+1}\right)^{n+1} \gt \left(1+\frac{1}{n} \right)^{n} $$   where $n \in \mathbb{N}$, I think we could use the AM-GM inequality for this but not getting how? I have the following code and I expect the resulting angle to be 135 degrees but whatevet I try, I get 90.  \documentclass{article} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}  \coordinate (A) at (1,0); \coordinate (B) at (-1,1);  \pgfmathanglebetweenpoints{A}{B} \edef\angleAB{\pgfmathresult} \node at (0,0) {\angleAB};  \end{tikzpicture} \end{document}   I also tried the following command without knowing what it means, it also prints 90 except one case. The only working case is when A=(1,0) and B=(-1,0), which it prints 180.  \pgfmathanglebetweenpoints{\pgfpointanchor{A}{center}}{\pgfpointanchor{B}{center}}   Why is that? Couldn't find any reference document for "pgfmathanglebetweenpoints" by the way, that's why I am asking here.  EDIT: B is corrected from (-1,-1) to (-1,1) Delete with Left Join in Oracle 10g I changed the /etc/environment to add more directories to the PATH variable.

Export Track Markers to csv I am trying to export markers from the Blender motion tracker and found the following script that will do exactly that:  for clip in D.movieclips:     for track in clip.tracking.tracks:         fn = 'data/tr_{0}_{1}.csv'.format(clip.name.split('.')[0], track.name)         with open(fn, 'w') as f:             frameno = 0             while True:                 markerAtFrame = track.markers.find_frame(frameno)                 if not markerAtFrame:                     break                 frameno += 1                 coords = markerAtFrame.co.xy                 f.write('{0} {1}\n'.format(coords[0], coords[1]))   It works but I have two questions:   How can I save the data on my Desktop rather than in folder in MacOS blender content where it saved right now. The following won't work:   fn = '/User/me/Desktop/data/tr_{0}_{1}.csv'.format(clip.name.split('.')[0], track.name) The resulting values I get do not represent the more user friendly marker values in den Blender GUI. Instead of x/y coordinates in screen coordinates, I get a value between 0/1. How can I convert them to those screen coordinates ?    Thanks for your help
