A crane is a bird as well as a machine.  A date is a fruit as well as an outing with your boy/girl friend.  What are words with multiple meanings called?
Is there a better alternative to ambiguous for a word with a wide range of meanings, difficult to find, because they become different in connection with person's opinion.
Hibernate has a handful of methods that, one way or another, takes your object and puts it into the database. What are the differences between them, when to use which, and why isn't there just one intelligent method that knows when to use what?  The methods that I have identified thus far are:   save() update() saveOrUpdate() saveOrUpdateCopy() merge() persist() What procedure should be followed post spilling fluids onto a MacBook keyboard? I know the first thing to do is dry with a towel the majority of the fluid. Next is to turn off the computer. Then flip over the laptop itself and whilst upside down cool dry the keyboard with a hairdryer for a few minutes. Also leave the computer upside down for a day or so. Is there anything I’m missing? "Within" and "in" when referring to time I know that both can mean "inside" but what I don't have clear is whether both mean the same when talking about time. For example:   The party is in two days = The party is within two days ??   According to this link  within means a limit that can be exceeded, so I'm wondering too if say "the party is within two days max" is correct or redundant. How to fix java.lang.UnsupportedClassVersionError: Unsupported major.minor version Why are lamps and mesh lights not illuminating anything? There are several techniques to do a 3 point lighting system.   How do you properly light a scene while using mesh planes as emission light sources?   I'm following , however despite setting up planes to act a lighting sources, the scene is still very dark.      Actual Blender file here: What are the differences between Factor Analysis and Principal Component Analysis? How can I find a mentor to critique my work? How do you check if a selector matches something in jQuery? In Mootools, I'd just run if ($('target')) { ... }.  Does if ($('#target')) { ... } in jQuery work the same way? How do you make a deep copy of an object? It's a bit difficult to implement a deep object copy function. What steps you take to ensure the original object and the cloned one share no reference? I saw him crossing the road.   I saw him cross the road.   Which one is correct and why? I am trying to find ways to quantitatively describe the shapes of various polygons. For my project, these polygons represent lakes, rivers, lagoons, and parks. So they can be almost any shape. One easy metric is to calculate perimeter vs. area, which is at best an only slightly useful metric. But I would also very much like to be able to say something about the 'roundness' of a polygon. Or how 'compact' the shape is on a map.  The only way I can think of doing this easily is to calculate the area of each polygon in relation to a bounding box for that polygon (which I already have). But this seems like a poor solution.  So now I am thinking of something more like this - take the centroid of the polygon, add on a series of buffers of increasing areas (say 50%, 100%, 150%), then compare how much overlap there is between each buffer and the original polygon. A perfect circle will have perfect overlap at 100%, and I can use the 50% and 150% buffers to judge how much and in what way each polygon differs.  But even that feels cumbersome, and like a poor workaround for what somebody else has probably already figured out far better.  For reference, at a minimum I will need to be able to look at the resulting indices for the shape of various polygons, and be able to make an educated guess as to their source (River? Reservoir with dendritic shape? Lake/Lagoon? Park?) How can I initialise a static Map? How would you initialise a static Map in Java?  Method one: static initialiser  Method two: instance initialiser (anonymous subclass) or some other method?  What are the pros and cons of each?  Here is an example illustrating the two methods:  import java.util.HashMap; import java.util.Map;  public class Test {     private static final Map&lt;Integer, String&gt; myMap = new HashMap&lt;&gt;();     static {         myMap.put(1, "one");         myMap.put(2, "two");     }      private static final Map&lt;Integer, String&gt; myMap2 = new HashMap&lt;&gt;(){         {             put(1, "one");             put(2, "two");         }     }; } I'm robotic engineer. I'm using OpenSCAD to model robotic components (gears, pulleys, parts, etc). But I need application to model physics and interaction of the components (for i.e. how will robot move if I will rotate current gear).  So, is it possible to import OpenSCAD models into Blender and model interactions in it?  I have models in STL format (for i.e. gears). I need to make reductor from it and see how it moves (if possible - measure rotation speed and torque). Check for missing fonts/characters in XeLaTeX? Because I began to use many Unicode characters (Japanese, some unusual diacritics, etc.) I switched from LaTeX to XeLaTeX to render my documents. Unfortunately, if a font is missing, the letters are simply left out (for example, when I had forgotten to specify the font for Japanese) without any error (and I can't seem to spot a warning either). I will read the result, but I prefer to get some early warning if some character isn't available. Is there any way to get a warning about characters that have not been rendered? An error would be even better. Combinatorial proof of $\sum_{i = 0}^{n} \binom{i}{r - 1} = \binom{n + 1}{r}$ and then use result to find a formula for $1^2 + 2^2 + \ldots + n^2$ Let $ \boldsymbol{x} $ be a vector of $n$ numbers in the range $ \left[0, c \right] $, where $ c $ is a positive real number.  What's is the maximum of the variance function of this $ n $ numbers? Maximum in the meaning what spread of the number will maximize the variance? What would be a tighter bound for other assumptions on the spread of the numbers.  The variance of the vector $ \boldsymbol{x} $ is given by:  $$ \operatorname{var} (\boldsymbol{x}) = \frac{1}{n} \sum_{i = 1}^{n} {\left( {x}_{i} - \overline{\mathbf{x}} \right )}^2 $$  Where the mean $\overline{\boldsymbol{x}}$ is given by:  $$ \overline{\boldsymbol{x}} = \frac{1}{n} \sum_{i = 1}^{n} {x}_{i} $$ JPA and Hibernate - Criteria vs. JPQL or HQL What are the pros and cons of using  or ? The Criteria API is a nice object-oriented way to express queries in Hibernate, but sometimes Criteria Queries are more difficult to understand/build than HQL.   When do you use Criteria and when HQL? What do you prefer in which use cases? Or is it just a matter of taste? I am going to Santa Monica for 4 weeks to polish my English in July and would like to volunteer at the Planetary Society located in Pasadena.  I am a Swiss citizen and have a biometric passport. However, I don't have any special visa, as there is no visa needed for the school I am attending and using the Visa Waiver Program, I am allowed to stay up to 90 days in the US.  Am I allowed to do volunteer work during my stay? How to prove or disprove following statement :     There are infinitely many primes of the form : $\lfloor \sqrt {3} \cdot n \rfloor $    Note: This is a problem I made myself.  There is a theorem that states :  $\lfloor nx \rfloor = \begin{cases}  n\lfloor x \rfloor, &amp; \text{if } 0 \leq \{x\} &lt; \frac{1}{n} \\  n\lfloor x \rfloor +1, &amp; \text{if } \frac{1}{n} \leq \{x\} &lt; \frac{2}{n} \\  n\lfloor x \rfloor +2, &amp; \text{if } \frac{2}{n} \leq \{x\} &lt; \frac{3}{n} \\  \vdots \\  n\lfloor x \rfloor +n-1, &amp; \text{if } \frac{n-1}{n} \leq \{x\} &lt; 1 \\ \end{cases}$  where $\{x\}$ is a non-integer part of $x$ .  Hence :  $\lfloor \sqrt{3}\cdot n \rfloor = \begin{cases}  n, &amp; \text{if } 0 \leq \sqrt{3}-1 &lt; \frac{1}{n} \\  n +1, &amp; \text{if } \frac{1}{n} \leq \sqrt{3}-1 &lt; \frac{2}{n} \\  n +2, &amp; \text{if } \frac{2}{n} \leq \sqrt{3}-1 &lt; \frac{3}{n} \\  \vdots \\  2n-1, &amp; \text{if } \frac{n-1}{n} \leq \sqrt{3}-1 &lt; 1 \\ \end{cases}$  How can I proceed from here ?
