Error in if/while (condition) {: missing Value where TRUE/FALSE needed How to find vendor and model of unknown drivers I reinstalled windows on a new machine and the drivers are not present for the product network card.   When in device manager all I get is the question mark and I am unable to figure out the actual name of the vendor or model of the card. This is making my search to find the correct driver hard.   Anyone know how I to find out more about the hardware that does not have drivers? Server 2012 Core (no GUI): Remote Server manager not working I am trying cmd --> MMC --> Server Manager and then connecting to my Server 2012 no GUI  but i keep getting the following error The WinRM client cannot process the request  I am unable to upload images right now  This is not related to other post "How to Remote Manage Windows Server 2012 in Server Manager?" because title and description of that post is quite different from what i am asking Do virtual particles actually physically exist? I have heard  pop in and out of existence all the time, most notable being the pairs that pop out beside black holes and while one gets pulled away. But wouldn't this actually violate the conservation of energy? How can you prove that a function has no closed form integral? Prove or disprove that $f(x) = \sin x/x$ is uniformly continuous over the interval $(0,1)$? I am thinking of $\lim_{x \to 0} \ {f(x)} = 1$ but I am confused as $x=0$ is not in the domain and also I want to write an $\epsilon$-$\delta$ proof. So any help is much appreciated!  Thanks! Does the Symmetric difference operator define a group on the powerset of a set? $G$ is the set of all subsets of a set $A$, under the operation of $\triangle\;$: Symmetric Difference of sets.  $A$ has at least two different elements.  I need to check if this is a group, and if it does to show if the group is abelian and/or finite.  Associativity - easy from Symmetric Difference. Identity element - empty group. Inverse element - each element is inverse to itself. Am I right?  abelian? finite? Python: Uniqueness for list of lists tikz arc with -latex arrow tip Why the arc does not fit over the circle if we use -latex arrow tip? Maybe some bug or some bad math computations?

Recommendations on a free library to be used for zipping files I need to zip and password-protect a file. Is there a good (free) library for this?  This needs to be opened by a third party, so the password protection needs to work with standard tools. Let $x$ be transcendental over $F$. Let $y=f(x)/g(x)$ be a rational function. Prove $[F(x):F(y)]=\max(\deg f,\deg g)$ Let $F$ be a field and $x$ transcendental over $F$. Let $y=f(x)/g(x)$ be a nonconstant rational function with relatively prime polynomials $f,g\in F[x]$. Prove $[F(x):F(y)]=\max(\deg f,\deg g)$.  My attempt: By replacing $y$ with $\frac{1}{y}$ if necessary we assume $\deg g\geq\deg f$. By the Euclid algorithm we assume $\deg g&gt;\deg f$. Then $\deg g=\max(\deg f,\deg g)$, let $n=\deg g$. Let $R(t)$ be this polynomial $$R(t)=yg(t)-f(t)=\frac{f(x)}{g(x)}g(t)-f(t)$$ Then $\deg R=\deg g=n$ because $n=\deg g&gt;\deg f$. The coefficients of $R(t)$ lie in $F(y)$ and hence $R(t)\in F(y)[t]$. Clearly $R(x)=0$.  Now I only have to prove $R(t)$ is actually the minimal polynomial of $x$ over $F(y)$. I believe the next step is to obtain a contradiction that $R(t)$ being reducible can lead to $f,g$ being not coprime, but I can't figure out how to do that.  P.S. A hint is preferred over a full answer. I want to do:  cat update_via_sed.sh | sed 's/old_name/new_name/' &gt; new_update_via_sed.sh   in my program.  But I want to use variables, e.g.  old_run='old_name_952' new_run='old_name_953'   I have tried using them but the substitution doesn't happen (no error). I have tried:  cat update_via_sed.sh | sed 's/old_run/new_run/' cat update_via_sed.sh | sed 's/$old_run/$new_run/' cat update_via_sed.sh | sed 's/${old_run}/${new_run}/' Stanley's Enumerative Combinatorics () contains next fact: 1.1.3 Example. Let f(n) be the number of n × n matrices M of $0$’s and $1$’s such that every row and column of M has three 1’s. For example, f(0) = 1, f(1) = f(2) = 0, f(3) = 1. The most explicit formula known at present for f(n) is $$f(n)=6^{-n}{(n!)}^2\sum\frac{(-1)^{\beta}(\beta+3\gamma)!2^\alpha 3^{\beta}}{\alpha!\beta!\gamma!^26^{\gamma}}$$ where the sum ranges over all (n + 2)(n + 1)/2 solutions to α + β + γ = n in nonnegative integers.   I need proof of this fact. (i.e. reference to book or articles that contains proof this fact). Setting up LVM Snapshot as a backup/restore point in ubuntu Why do some tag info pages show who created them and others don't? Some  show who created the tag:    while  don't. I'm pretty sure I created that one as well, if you hover over the timestamp you can see when it was created:    which more or less matches with  where I created the tag:    I understand that some tags like  were probably created by the Community user while the site itself was created (so it ), but some newer tags like   even though  still has an account here.  What's going on here? Would this also mean I wouldn't get a  for  if I ? Affiliation for a retiree This question is similar to   and  except that I am a retiree.  I intend to submit a paper to a journal without mentioning any affiliation because I am no longer employeed. I have been thinking about a footnote in the paper indicating I am a retiree from my former employer for two reasons: I am receiving pension from the company pension fund and it is a well-known company in U.S. Using their name may make me look good. On the other hand, I feel like it's cheating because I am not their employee anymore. Is there a way to do proportional editing only on specific vertices? How can I say this? In Windows Vista, I have tried to set the setting 'the following number of lines at a time' to zero. I assumed my scroll wheel would not scroll anymore. But it still works.  I'm trying to disable the wheel because my RSI complaints worsen when using the scroll wheel often.  Does anyone have an idea on how to achieve this?
