Well a silly question to ask, shall we consider *shoes * as singular or plural? I would say that it is plural for it has a singular form shoe.   But then why do we write Either my shoes or your coat is always on the floor ?
The following sentence refers to an apocalyptic story where money no longer has any value:     A can of sardines, radio batteries, or a bicycle is/are more precious than money.   Should I use is or are after the series?
Howto wildcard SELECT * to query all fields of objects in APEX? I have created sObject and I need all the fields and I have many. Is there a way I can directly get all of them rather then typing each one of them. I want to untriangulate every object in my scene with this script:  import bpy  for ob in bpy.data.objects:     bpy.ops.mesh.tris_convert_to_quads(limit=0.9, uvs=False, vcols=False, sharp=False, materials=False)   But it doesn't work in object mode, any ideas on how I can get it working? Call to a member function prepare() on a non-object PHP Help Why doesn't the last digit method work for divisibility by 4? I wish to explain to a grade 5 kid, the answer to the question - 'When can we know that the observing the last digit of a number will not be sufficient to determine its divisibility by a given N?'  For example - It doesn't work for 3, because we get all sorts of digits, i.e. from 0 to 9, at the units place. The same reason works for 7 and 9.   But what would be a convincing argument for 4 and 8? Even though the last digits form a pattern - 0, 2, 4, 6 and 8 - but we're still not sure about its divisibility. 2D and 3D vectors in Tikz I would like to draw some 2D and 3D vectors in Tikz with certain properties. The following primitive graph sums what I desire:   I just need the first quadrant of the Cartesian coordinate system for my representation.  I need the vector to be connected to the respective values on the distinct dimensions(not a projection, just orthogonal dashed lines).   The code segment below does what I want to achieve in 3D with two exceptions:  The projections on the xy plane and z dimension are given instead of connecting the head of the vector to the corresponding value in each dimension.  Numerical values are missing in dimensions.   Code: \documentclass[tikz]{standalone} \usepackage{tikz-3dplot} \begin{document}  \tdplotsetmaincoords{60}{120} \begin{tikzpicture}     [scale=3,     tdplot_main_coords,     axis/.style={-&gt;,blue,thick},     vector/.style={-stealth,red,very thick},     vector guide/.style={dashed,red,thick}]  %standard tikz coordinate definition using x, y, z coords \coordinate (O) at (0,0,0);  %tikz-3dplot coordinate definition using r, theta, phi coords \tdplotsetcoord{P}{.8}{55}{60}  %draw axes \draw[axis] (0,0,0) -- (1,0,0) node[anchor=north east]{$x$};     \draw[axis] (0,0,0) -- (0,1,0) node[anchor=north west]{$y$};     \draw[axis] (0,0,0) -- (0,0,1) node[anchor=south]{$z$};  %draw a vector from O to P \draw[vector] (O) -- (P);  %draw guide lines to components \draw[vector guide] (O) -- (Pxy); \draw[vector guide] (Pxy) -- (P); \end{tikzpicture} \end{document} How does Ubuntu partition the disk when we choose "Erase disk and install Ubuntu" during installation? How will Ubuntu automatically allocate the disk partition sizes when we select Erase disk and install Ubuntu during installation?    Can the settings for automatic space allocation be changed? I accidentally opened Orca Screen Reader from the Dash when I was trying to open Screenshot. Now everything I type or click on is spoken out loud.  How do I make it stop?  For reference, here is a screenshot of Orca Screen Reader running: If $p$ and $q = 2p + 1$ are both odd primes, show that $-4$ and $2(-1)^{(1/2)(p-1)}$ are both primitive roots modulo $q$.   I cannot get heads nor tails of how to even start this let alone finish it Inherited values between polygons in QGIS In this project, I have three polygons, see the image below  'Polygons_From', includes input attributes, i.g. &quot;Value_1&quot;, &quot;Value_2&quot;, &quot;Value_3&quot;, and $area for each quadrate (on the image there are two types of them). 'Polygons_To' polygons for which new values &quot;Value_1_new&quot;, &quot;Value_2_new&quot;, &quot;Value_3_new&quot; need to be defined 'Border' defines an area where the calculation should be done.   My task is to transfer values from 'Polygons_From' into 'Polygons_To' based on a certain aspect/ratio. Of course, I can simply achieve it with the 'Union' function as was suggested in . It uses $area-factor, but perhaps there are better approaches that will lead me to a much more efficient output? So, I am asking for a recommendation regarding the technique/workflow that can be applied in QGIS 2.18. Shall I consider only $area or there are some other criteria? Moreover, I looking forward to finding some papers that may improve my general understanding of the methodology.  References: Photoshop CS6 Resize Rectangle with Rounded Corners This question is about Photoshop CS6. Hopefully the feature was added in this version. Before posting I looked up Google and  and  but didn't find an answer for CS6.  So the question is: Is there a feature within CS6 or a script that allows to resize a vector element with rounded corners without using the Direct Selection Tool (white arrow tool) and not changing the border radius? What would be great would be something like simply using the transform tool or something like a grid resize tool. I've got a problem using \label and \ref in Texmaker 3.1 (MiKTeX 2.9). When I put label somewhere, i got a frame with label name in it. How can I hide it?  \begin{figure}[h] \includegraphics[width=0.75\textwidth]{img/2}\caption{SomeCaption} \label{fig:4eb1} \end{figure} $\frac{w}{w_1}-1=4$ $4\leqslant n\leqslant3$, using (pic. \ref{fig:4eb1}),blah-blah.   PS: Sorry for my awesome English. :) In the Prisoner of Azkaban, Harry and Lupin could practice the patronus on the boggart, but when Harry was in the final task in the Goblet of Fire, he tried to use the patronus on the boggart, it didn't work and he then moved on to use ridikkilus.  Why could he use a patronus against the boggart, but then not in another? Why does the x86-64 / AMD64 System V ABI mandate a 16 byte stack alignment? I read the answers in this question, but they still leave my question open:   I didn't find a way in the Google Webmaster Tools to invoke a re-download of my robots.txt.  Through some error, my robots.txt was replaced with:  User-agent: * Disallow: /   And now all my content was removed from Google search results.  Obviously, I'm interested in correcting this as soon as possible. I already replaced the robots.txt, but I can't find a way to make Google update the cached version. Proving a graph has no Hamiltonian cycle What books, journals, and/or electronic resources have you found most valuable for expanding your knowledge in the GIS field, and why? Attribute editing in QGIS on geoJson file We have vector files in the format of geoJson files. We need to keep it in geoJson format as it is picked up by mobile devices via Restful services.  The problem is we want to change the attributes of the features in QGIS but it seems like this is not possible. We don't have to add or remove columns. We simply need to edit the existing data.  Is there a work around for this?  Are there any plugins that I can download that will allow me to do this in QGIS? Prove that if $a+b+c$ divides $abc$, then $a+b+c$ must be composite. How (and why) use stderr for both reading and writing? According to , less reads navigation commands from stderr if it's not able to open /dev/tty.  This seems puzzling, since I've never seen anything write to another program's stderr stream, and I don't know how I would even accomplish that.  What is the purpose of stderr being open for both reading and writing? And if this is useful, how do I make use of it on modern systems? (Is there some arcane syntax to pipe something into stderr instead of stdin, for instance?) Can a level 1 Warlock Cast a 4th level spell from 8th level Sorcerer with their warlock pact magic spell slots? Can my player’s multiclass Warlock 1/Sorcerer 8 cast the higher level sorcerer spells from with their warlock pact magic spell slots?  My player argued that he could now cast his 4th level sorcerer spells with his level 1 warlock  spells slots. I think he interpreted pact magic as "highest spell slot possible",  so he figures that since he has 4th level spell slots, he interprets that the warlock spell slots are 4th level slots now too.
