This has been stressing me out for a couple of hours now. I'm using MiKTeX 2.9 with Texmaker as the editor. I've been trying to use a .bib file as an external bibliography, which I've typed up in a text document. Every guide I've seen has said that I've needed to "run" bibtex, and they talk as if bibtex is a program, but I can't for the life of me find bibtex as a piece of software anywhere on the internet.   Here are the important parts of my main file:  \documentclass[11pt,a4paper]{article} \usepackage{graphicx} \usepackage[utf8]{inputenc} \usepackage[english]{babel} \usepackage{comment} \usepackage{amsmath} \usepackage[ backend=bibtex, style=alphabetic, sorting=ynt ]{biblatex} \usepackage{float}  \bibliography{biblio} \addbibresource{biblio.bib}  \begin{document}  Document text here.  \printbibliography   \end{document}   And here is my bibliography:   It gives me a fair few warnings.   1: 'babel/polyglossia' detected but 'csquotes' missing.  1: 'Data encoding is 'utf8' 131: 'Citation 'EPS' on page 6 undefined (defined in the .bib file 134: 'Empty bibliography' This is the big one. Bibliography clearly not empty! 1: 'There were undefined references' 1: 'Please (re)run BibTeX on one file(s): (biblatex)diss (biblatex) and rerun latex afterwards'   I don't understand how I can "run" biblatex? Isn't biblatex the language?   What am I doing wrong?
I've browsed the forums and found a number of posts that have addressed this issue, but none of the solutions seem to work for me. I have the following script that I just copied from the bibtex home page to get familiar with it. Instead of the citation number I get a question mark. I compile using Latex+Bibtex+Latex+Latex+PDFLatex+ViewPDF just as has been previously suggested and the problem persists.   \documentclass[11pt]{article} \usepackage{cite}  \begin{document}  \title{My Article} \author{Nobody Jr.} \date{Today} \maketitle  Blablabla said Nobody ~\cite{Nobody06}.  \bibliography{mybib} \bibliographystyle{plain} \end{document}   My bibliography (Bib.bbl)  @misc{ Nobody06, author = "Nobody Jr", title = "My Article", year = "2006" }    Looking at previous posts one thing that is concerning is that my .bbl looks empty as shown below. Further, I don't have a .blg  \begin{thebibliography}{}  \end{thebibliography}
FICA was not withheld from my paycheck Hello personal finance,  I was filing my taxes for 2016 and I just found out that I transitioned from Non-Resident-Alien to Resident Alien around September last year by passing substantial presence test. After doing some research, I have found out that I qualify as a resident alien for the whole tax year (from January 2016).   Unfortunately, my employer did not know about this change in status, so for all of 2016 no Social Security or Medicare taxes were withheld.   I have found out that I need to correct this, and I need help figuring out a few things.    Should I have a W-2 re-issued? I spoke to two accountants and one said I should, the other said I shouldn't. I don't know which one to believe.  Who pays for the FICA I should have paid last year? Is it my employer's problem to fix or mine?  Should I file the taxes with the old or the new W-2?  As best as I understand it, the new W-2 will be written as if I made this contributions. So there will be a discrepancy between what I actually earned and what the W-2 says. How should I handle this discrepancy? Declare it as extra income? Or claim it back in case I earned less than I should have? How to determine the current widget's parent container (sidebar widget id) What steps does a manuscript typically go through from submission to publication (or rejection) in a typical journal?

MySQL: "UPDATE command denied to user ''@'localhost'" The definition of derivative of a function $f(x)$ is $$\lim_{h\to0} \frac{f(x+h)-f(x)}{h}$$  Using this definition, the derivative of $\sin\sqrt{x}$ will be:  $$\lim_{h\to0} \frac{\sin\sqrt{x+h}-\sin\sqrt{x}}{h}$$  $$\lim_{h\to 0} \frac{\cos\left(\frac{\sqrt{x+h}+\sqrt{x}}{2}\right)\sin\left(\frac{\sqrt{x+h}-\sqrt{x}}{2}\right)}{h}$$  Now i got stuck. How to find the limit or simplify this expression?  I get intuition that we have to use $$\lim_{x\to0}\frac{\sin x}{x} = 1$$  but that too is leading no where. I am unable to remove h from denominator.  NOTE  I know the derivative of $\sin\sqrt{x}$ is $\frac{\cos\sqrt{x}}{2\sqrt{x}}$ using chain rule, but this exercise was given to us for practice using division quotient.

How do different difficulties work on story missions? When selecting a story mission, I can choose between "Easy" and "Hard".  Next to the difficulty, the game displays some kind of level.  However, when you start the mission, you still end up in the common map area with other players.  What exactly changes when you select a higher difficulty?  Is it possible to see other players playing on "Easy" when you select "Hard" before entering the mission zone where respawning is restricted?

Thanks once again!!! check if Gutenberg is currently in use How can I check if the editor that is currently being used is Gutenberg in a WordPress plugin?

I'm trying to optimize my road system a bit, mostly converting regular small roads into one-way roads. But the only way I can see to do that is to remove the old road entirely and build a new one. I can't seem to just build over the old one.   I can understand that limitation in cases where the new road type is larger, but it should be possible to upgrade to roads with the same size without tearing down the old road manually.   Is there an easier way to convert or upgrade roads, or do I have to manually remove the existing road every time? I attended a business meeting in the Midwest and one of our clients took our management team and a few other business partners to dinner at an awesome Mexican restaurant. When the appetizers were served I commented that it was a wonderful presentation and that everything looked very fresh, including the avocado slices.   Speaking to the woman seated across from me I said that even though I use a good amount of lemon juice, whenever I prepare avocados they still turned dark pretty quickly. This happens whether they are sliced, used in guacamole, etc. She responded that the secret is to use lime juice. She proceeded to tell me that she was born and raised in Central America and that it is customary there to use fresh limes or juice rather than lemon.  I have tried it and lime seems to work much better than lemon, so it would stand to reason that they are more acidic. However, I never thought there was that much difference. So, on to the questions.  Are limes more acidic than lemons? Are there any other differences in their properties that could make a difference?

What would be a good term for continuous testing post-deployment? Does someone falling into a black hole see the end of the universe? This question was prompted by . Notoriously, if you calculate the Schwarzschild coordinate time for anything, matter or light, to reach the event horizon the result is infinite. This implies that the universe ages by an infinite time before someone falling into the black hole reaches the event horizon, so could that person see the universe age by an infinite time?  To be more precise, suppose the observer starts falling from rest at time $t = 0$ and some initial distance $r &gt; r_s$. If we wait for some time $T$ then shine a light ray at the falling observer. Will the light ray always reach the falling observer before they cross the event horizon? If not, what is the formula for the longest time $T$ that we can wait and still be sure the ray will catch the observer? If $T$ is not bounded it implies that observer could indeed see the end of the universe.  I can think of a qualitative argument for an upper limit on $T$, but I'm not sure how sound my argument is. The proper time for the observer to fall to the event horizon is finite - call this $\tau$. The proper time for the light ray to reach the horizon is zero, therefore the light ray will reach the observer before they cross the event horizon only if $T &lt; \tau$. Hence $T$ is bounded and the observer won't see the end of the universe.  I think a more rigorous approach would be to determine the equations of motion (in the Schwarzschild coordinates) for the falling observer and the light ray, and then find the condition for the light to reach the falling observer at some distance $\epsilon$ from the event horizon. Then take the limit as $\epsilon \rightarrow 0$. In principle this seems straightforward, but in practice the algebra rapidly defeated me. Even for a light ray the radial distance:time equation isn't closed form (Wolfram claims it needs the $W$ function) and for the falling observer the calculation is even harder. Proof for triangle inequality for vectors Generally,the length of the sum of two vectors is not equal to the sum of their lengths. To see this consider the vectors $u$ and $v$ as shown below.  By considering $u$ and $v$ as two sides of a triangle, we can see that the lengths of the third side is $\| u + v \|$ and we have $\| u + v \| \leq \|u\| + \|v\|$.  Under what circumstance equality occurs and how can one prove that?
