How can I change the strip.background color in ggplot2 facet_grid based on the value within the facet label?
ggplot2: facet_wrap strip color based on variable in data set
Help with proving that $\pi$ is irrational Is the possessive of "one" spelled "ones" or "one's"? I've been confused about this as long as I can remember. Should it be:     One should do ones duty.   or     One should do one's duty.   I'm guessing it should be the latter. But that doesn't sit well with the possessive pronoun 'its'. For example:     It is its own purpose.   vs.     It is it's own purpose.   Here, the former seems clearly correct. I'm interested in understanding which neural network architecture is currently the state of the art (sometimes abbreviated "SOTA") with respect to standard image classification tasks such as MNIST, STLN-10 and CIFAR. This is challenging because new results are published frequently, and it can be hard to keep up. Is there a resource or website which tracks the best results for these tasks? Yes,  but there must be a canonical or most efficient or most concise way. I'll add answers I know of and see what percolates to the top.  To be clear, the question is how best to read the contents of a file into a string. One solution per answer. Evaluate these infinite products $\prod_{n\geq 2}(1-\frac{1}{n^3})$ and $\prod_{n\geq 1}(1+\frac{1}{n^3})$ What is   $\prod\limits_{n\geq 2}(1-\frac{1}{n^3})=?$ $\prod\limits_{n\geq 1}(1+\frac{1}{n^3})=?$   I am sure about their convergence. But don't know about exact values. Know some bounds as well. For example first one is in interval (2/3,1) and second one is in (2,3). My server is still vulnerable to heartbleed even after I update OpenSSL I have an Ubuntu 12.04 server. I have updated the OpenSSL package in order to fix the heartbleed vulnerability. But I am still vulnerable even, even though I have restarted the web server, and even the whole server.  To check my vulnerability I used:       dpkg gives:  dpkg -l |grep openssl ii  openssl  1.0.1-4ubuntu5.12   Secure Socket Layer (SSL) binary and related cryptographic tools   (launchpad.net/ubuntu/+source/openssl/1.0.1-4ubuntu5.12) Why weren't everyone on Haruun Kal made a Jedi? I'm studying for an abstract algebra exam and one of the review questions was this:     Let $X$ be a set, and $\mathcal P(X)$ be the power set of $X$. Consider the operations $\Delta$ = symmetric difference (a.k.a. "XOR"), and $\bigcap$ = intersection.   a) Does $\Delta$ and $\bigcap$ make $P(X)$ into a ring?   b) If so, is it a ring with unity?   c) Is the ring commutative?   d) Is it a field?   For parts a) and b), I think it does form a ring with unity, but I'm not quite sure how to get started on proving it.   For part c), it is a commutative ring since $\mathcal P(X)$ is closed under symmetric difference and intersection, right?  Not even sure how to get started on d).  I'd really like to understand this question fully, so any kind of input would be tremendously helpful. Thank you! I'm using terminal-ide  which is basically a terminal for android with all sorts of utilities. One is able to create bash scripts for example. Is there a way to create an icon on the home screen that will launch one of these scripts? How did the Death Star move? In the Star Wars saga, one of the most iconic weapons of the Empire was the Death Star: a self sustained weapons platform the size of a moon, with the capacity to destroy a planet. in A New Hope, we see the first Death Star in close proximity to the planet Alderaan, holding the planet hostage as the Empire tries to deduce the location of the Rebel Alliance's headquarters. In Return of the Jedi, we see the second Death Star in "dry dock" over the forest moon of Endor as it is being constructed.  My question is: How did the Death Star move? I imagine a spherical space station the size of a moon would be utterly massive, requiring a massive amount of thrust to move it. If it was constructed in low orbit of an inhabited planet/moon, the gravitational field would be immense, consisting of the planet/moon's gravity, and the Death Star's own considerable gravity. Breaking that gravitational field would be a massive task, yet we see no thrusters or engines on either Death Star. Were they hidden, stored under the station's surface while not in use? Was the station towed by another vessel? 2 prong to 3 prong outlet help New 16GB of RAM installed yet I see 15.3 on my system. Why? Just switched 4GBs to 16GBs of RAM. However, when I look at how much memory I have, it says 15.3. I'm just wondering why did my memory drop down when I just installed 16 GBs of RAM. Can an abstract class have a constructor?  If so, how can it be used and for what purposes? How to convert int[] to Integer[] in Java? Creating Digital Terrain Model from Digital Elevation Model using ArcGIS for Desktop?

Compactly supported continuous function is uniformly continuous Is given metric space $(M, d)$. Let $A\cap B = \emptyset; \,\,\text{dist}(A,B):=\inf\{d(x,y):x\in A, y\in B\}$. $A, B$ are both closed sets. Is it possible that $\text{dist}(A,B)=0$?  The first thought comes into mind is that obviously $\text{dist}(A,B)&gt;0$, but possibly there are some tricky $d$ and $A, B$ so that it's untrue.  Thanks in advance! Mankind prepares for a war with aliens by warring among itself I am looking for the title or author of a atory I read back in the 90's, no idea when it was written. The plot goes something like this: Humanity has gained access to space travel and sends 9 or 12 survey ships towards galactic center, only 1 returns with stories of an enemy so rapacious that humanity starts preparing for war. After a long time, the enemy hasn't shown up and people begin to doubt the need to keep building for war. The government engineers a plan to turn the core systems against the fringe worlds and start warring amongst ourselves so that we may be prepared for when the real enemy shows up.  Written with the focus on one spaceship captain battling in our own internal war. What is the difference between using IDisposable vs a destructor in C#? When would I implement IDispose on a class as opposed to a destructor?  I read , but I'm still missing the point.    My assumption is that if I implement IDispose on an object, I can explicitly 'destruct' it as opposed to waiting for the garbage collector to do it.  Is this correct?  Does that mean I should always explicitly call Dispose on an object?  What are some common examples of this?
