How do I set values for a Boolean field?
How do I set a Boolean field with "yes" and "no" values?
Prove that the product of four consecutive positive integers plus one is a perfect square I need to prove the following, but I am not able to do it. This is not homework, nor something related to research, but rather something that came up in preparation for an exam.     If $n = 1 + m$, where $m$ is the product of four consecutive positive   integers, prove that $n$ is a perfect square.   Now since $m = p(p+1)(p+2)(p+3)$;     $p = 0, n = 1$ - Perfect Square      $p = 1, n = 25$ - Perfect Square      $p = 2, n = 121$ - Perfect Square   Is there any way to prove the above without induction? My approach was to expand $m = p(p+1)(p+2)(p+3)$ into a 4th degree equation, and then try proving that $n = m + 1$ is a perfect square, but I wasn't able to do it. Any idea if it is possible? How can I multiply each item in an array easily with PHP? Using sed with special characters How to explain in layman’s terms the significance of the difference of qubits of the D-Wave and IBM QX? So, @AndrewO mentioned recently that he has had 'encounters' with people wondering why D-Wave has a lot more qubits than IBM. Of course, this comparison is faulty, since the IBM and D-Wave's machine may both exploit quantum effects to a certain degree, IBM's machine matches the thing the TCS people call a 'Quantum computer' a bit more than D-Waves's alleged quantum annealer.   How do you explain to a novice why IBM is still reaching important milesstones, even though the D-Wave has a lot more 'qubits'. I understand that an easy answer is, 'well, you're comparing apples and pears', but that is merely relying on your possible authority and simply doesn't explain anything!   How can you explain that those devices are different, how can you dispell the myth that the number of qubits is not the only metric to judge quantum devices? (preferably to a layman, but assuming basic (undergrad?) physics knowledge is ok, if needed) In  (2017), Logan seems to be dying from sort sort of ailment, that prevents him to heal properly and seems to be decaying his body in a way that wasn't happening in any of the other films his character appears in.  I don't recall that this is being explained in the film. The Wikipedia page only mentions "adamantium poisoning" and "his healing factor fading", but it is not backed up with citations, so I would love to get an in-depth answer for this question, maybe using excerpts from the comic or original source material.  What is happening to Logan? Why is $\pi$ irrational if it is represented as $C/D$? How can I prove that if $\gcd(a, b) = 1$, then $\gcd(ab, c) = \gcd(a, c) \times \gcd(b, c)$?  By eea there exists $ax+by=1$ from $\gcd(a,b)=1$ so a and be are co-primes there also exists $dk=a$ and $dj= b$ where $d=\gcd(a,b)=1$ this is all the information I have gathered from the question but I dont know how to approach and solve it. Can anyone help explain to me how to arrive at the answer? Thanks! Can I use SharePoint Designer 2013 to edit SharePoint 2010 sites?

I had this problem a week or two ago and I posted here but nothing from the suggested solutions seemed to work. I have managed to get some more details on it, in case anyone can help me, because this issue is causing me huge productivity problems and I really want it solved.  So I'm using Linux mint distribution, and I've installed Lyx via the software manager. Every time that I open a new document, I get an error claiming that some files are missing, and until they are installed, compiling the files or exporting them as pdfs is not possible. The file in question is called "extarticle.cls". Additionally, under Document->Settings->Document Class, every document class is marked as unavailable.  Here is the thing though.. this file is not missing... I have located it inside a folder associated with Lyx. It's definitely not missing.  I really need help with this one guys... It's been weeks since the problem came up and I really just want to be rid of it.. Why does this thing not work? Any help? Prerequisites for AIC model comparison What are exactly the prerequisites, that need to be fulfilled for AIC model comparison to work?  I just came around this question when I did comparison like this:  &gt; uu0 = lm(log(usili) ~ rok) &gt; uu1 = lm(usili ~ rok) &gt; AIC(uu0) [1] 3192.14 &gt; AIC(uu1) [1] 14277.29   This way I justified the log transformation of variable usili. But I don't know if I can AIC-compare models when for example the dependent variable is different?  Ideal answer would include the list of prerequisites (mathematical assumptions). How do I get my Epson Scanner working on Ubuntu 13.10 I have the Epson SX218 with a built-in scanner. The printer works fine but if I want to scan something simple scan says no scanner found.  Any ideas what I can do?  By the way, how can I check the ink level of the printer?? Change all @username references in comments when a user changes their name? The fact that a user can change their name at will can lead to some confusion in the comments.  For instance, suppose a user named "foo" changes his name to "bar", all those comments signed by "foo" are now signed by "bar", but responses to "bar"'s comments still start with "@foo".  Could those "@foo" references in comments be changed to "@bar"?    A brief discussion on this has set me straight.  I didn't think it through.  Request withdrawn. What is the maximum value of the Process ID?  Also, is it possible to change a Process ID? Formula Error: Syntax error.

Why do we say "eat healthy" instead of "eat healthily", even though the latter is the only "correct" one, according to the comments in      What came first: ads saying "eat healthy", or the grammatical acceptability of such a phrase?    Merriam-Webster does not consider "healthy" to be an adverb, unlike "quick": , and therefore this question is not a duplicate of Why is King Arthur female? Why is Iskander tall? I've watched both the Fate/Zero and Fate/Stay Night anime (including the Unlimited Blade Works movie), but none of the visual novels, so no spoilers from that unless they are light spoilers. One thing that bothered me was that despite the fact that heroic spirits are defined by the public opinion/view of them, some heroes had qualities that were in direct opposition of what the public thought.  We know that heroic spirits, being sealed on their Throne of Heroes, are meant to be completely unchanged. This is the entire point of the Throne of Heroes. But this seems to be in opposition of the previous fact that heroic spirits are defined by what others think they are. Then there are Counter Guardians who are completely different, I believe, in that they are not sealed on their Throne of Heroes.  One particularly important Counter Guardian of the series is Arturia, or Saber. Arturia is female, despite the fact that she was treated by even her contemporaries as male, and has gone done in history as male. In fact, there isn't even any small hint as to Arturia's gender being anything other than male in our history, or the history of the Nasuverse (I believe). This being true, shouldn't Arturia be male?  This not being the case shouldn't Arturia be erased, or else create instability in the World? Same with Iskander. In history he is known for being pretty short, even for a Macedonian. That he is very tall means there is an incongruity with human knowledge and true fact.  Furthermore, in the Unlimited Blade Works movie Archer is revealed to be Heroic Spirit Emiya. If Heroic Spirit Emiya is summoned before he is even a hero, or acquired his gift from the World, etc., then how is it that Heroic Spirit Emiya is even strong at all? The power of a Servant being based on their popularity at the time of their summoning, Emiya should be weaker than pretty much every other Servant, and then some.  Maybe I'm just over-analyzing things, or I have some misconception. In any case, answers are appreciated. Is there a way to scale up the bevel object on one end of a curve, a little bit over each point?  I notice the vertex "weight" slider will tweak how much influence each vertex has on the others, is there something like this that can scale the bevel object up a little bit?  Preferably with the option to constrain X,Y,Z independently Why does the order in which libraries are linked sometimes cause errors in GCC? Why does the order in which libraries are linked sometimes cause errors in GCC? Performance difference between dot notation versus method call in Objective-C You can use a standard dot notation or a method call in Objective-C to access a property of an object in Objective-C.  myObject.property = YES;   or  [myObject setProperty:YES];   Is there a difference in performance (in terms of accessing the property)? Is it just a matter of preference in terms of coding style?
