When I try to install any version of Wubi,appears message which asks  me to Burn DVD E. And no choice to change it,or reject. Regards, M.Shahbazov
Is there any Windows installer (wubi) for Ubuntu 14.04 LTS?  When I mount the .iso file with Daemon Tools and run wubi.exe, it just asks me if I want to reboot (I think that's useful only when the .iso  is burned on CD), so is there no "real" installation?
$L^p$ and $L^q$ space inclusion Let $(X, \mathcal B, m)$ be a measure space.  For $1 \leq p &lt; q \leq \infty$, under what condition is it true that $L^q(X, \mathcal B, m) \subset L^p(X, \mathcal B, m)$ and what is a counterexample in the case the condition is not satisfied? Export My Stack Overflow Data Is there a first party (or third party?) way to export just my data out of Stack Overflow?  I realize there's a massive Creative Commons data dump.  I'm interested in knowing if there's a quick and easy way for me to get my posts dumped out in some plain text file format for easy  personal archiving. How can I retrieve \thepage (or detect a page change) from Lua in LuaTeX? I am writing (contributing to) a LuaLaTeX package where a Lua function is used to generate images that are inserted in the LaTeX document.   One piece of information we need is the current page number to determine if we're on an odd or even page (I know that this is not that trivial, and I know about some strategies beyond \thepage). We set a Lua variable when we're still in the LaTeX part, and so far this works pretty well.  However, now it turns out that the sequence of images we create may be distributed on several pages, and we would really like to reflect that because our images may behave differently on odd and even pages.  Basically what we have is a series of  tex.print('\\includegraphics{something}\\par')   statements, executed in a loop within one Lua function.  Now the question: is there any way to either directly detect a page change between two such graphics or repeatedly retrieve the current page within such a loop?  All the solutions I have found for determining current odd or even state are in LaTeX itself. I know how to use \directlua to retrieve a value for use in LaTeX, but is there a way to do the opposite - retrieve a LaTeX value from within LUa?  Edit: to respond to TeXnician's comment and answer: When I modify the example code so it produces repetitions of paragraphs it seems that the page counter won't get updated within one Lua chunk:  \documentclass{article}  \newcommand\printluapage{%     \directlua{for i = 1, 60 do tex.print(tex.count['c@page'])          tex.print([[\par]]) end} }  \begin{document} \printluapage  New command  \printluapage  New command  \printluapage \end{document}   The page number is only updated with each new call of \printluapage. I just installed Lyx 2.1 on my computer for the first time. I wanted to create my first trial pdf but switching to viewing mode is for some reason not working with the Acrobat Reader DC. I tried many options found on the web but I am afraid my little knowledge is not sufficing to make it work.  I would really appreciate a detailed answer :)   Thanks. Assessing approximate distribution of data based on a histogram Suppose I want to see whether my data is exponential based on a histogram (i.e. skewed to the right).   Depending on how I group or bin the data, I can get wildly different histograms.   One set of histograms will make is seem that the data is exponential. Another set will make it seem that data are not exponential. How do I make determining distributions from histograms well defined? Problem putting matrix operations in an equation Possible Duplicate:          I'm trying to use official equation container for the first time, and it's giving me some trouble.  I have this equation of a simple matrix operation, and LaTeX isn't liking it.  What's wrong with this statement?  \begin{equation}      y = \begin{bmatrix}         T &amp; I      \end{bmatrix}     \begin{bmatrix}         a \\         e     \end{bmatrix}  \end{equation} Why was the MCU Super Soldier program considered a failure? In Marvel Cinematic Universe, military tried to create super soldiers like Hulk, but they failed. So, the program was shut down.  Where did they fail? Didn't Blonsky get Wolverine-type super healing capability? Why couldn't it make the military stronger? Other than this, wasn't Abomination a success (despite the fact that it wasn't an original work of the military)? He was defeated by Hulk, but enemy forces don't have a Hulk. When it comes to anger, who cares as long as you are focused on the target? Abomination was indeed in full control and he was always after Hulk. I am currently visiting the USA from the UK (I am a UK citizen) and am intending on staying here for the full 90 days under the Visa Waiver Program.     How long would I have to stay out of the US at the end of this period before returning again?    Would I have to return to the UK, or could I stay with friends in another country (such as Canada) for a while? ls command operating differently depending on recipient MacBook Pro: How to disable discrete GPU permanently from EFI? Close and flag links do nothing on mobile site This morning (it's about six AM here) I find that I can no longer submit close votes; the link just jumps to the beginning of the page.  I'm on iOS, using a third-party browser called Grazing, but a brief check with Mobile Safari shows the same problem there.   Here on Meta, where my score is much lower, I only get a "delete" link on my own question, and that works fine. (Oops :-))   Update: As per comments, this affects the "flag" link, too, which doesn't even scroll to the top of the page. Update 2: Latest comment suggests this affects Android, too. Update 3: This also affects desktop computers when viewing mobile (when you click "mobile" in the footer) Update 4:  mentions Windows 8, too; simply deleting platform-specific tags How should I deal with becoming discouraged as a graduate student? I am a third year (starting fourth year in the fall) PhD student in mathematics. I've passed all qualifying exams and am currently doing research. As far as I can tell, I am not doing poorly. I have the good fortune of having a great advisor, being in a very supportive department, and having friends and family who genuinely care about my success.   The fact is research is hard. It appears to consist primarily of staring at a problem for days and days and days without getting anywhere. Sometimes, rarely, I do figure something out and that feels wonderful, but the overwhelming majority of my time appears to be spent banging my head against a mostly figurative wall. I am not complaining about the material being hard, and I am not averse to putting in hard work, but I get frequently discouraged when I realize the vast volumes of mathematics that I yet know nothing about (and probably never will). It's very hard to quantify progress - in particular, there are too few tangible returns after too many hours worked. I find myself thinking along the lines of "Oh, if only someone actually smart were thinking about this problem they would have solved it in moments" and so on.   I've talked about this to some number of people; here is some advice I have received:   Take a day off. Putting in hours upon hours of trying things doesn't magically lead to a solution, particularly if the brain is tired and just wants to sleep. Have a hobby. Since math research doesn't exactly provide instant gratification, a hobby might provide some instead.  Talk to other graduate students. Realize that many graduate students go through this.   I'm interested to know how other folks have dealt with being discouraged as a graduate student. Does it get better with time and experience? Is this a sign that research is not for me and that I should seriously consider a life outside academia?

Many thanks in advance. How to harden an SSH server? Prove that if $p \equiv 3 \pmod{4}$ then $x^2+y^2 \not \equiv 0 \pmod{p}$ Let $x$ and $y$ be integers not congruent to $0$ modulo $p$ where $p$ is a prime. Prove that if $p \equiv 3 \pmod{4}$ then $x^2+y^2 \not \equiv 0 \pmod{p}$.   I thought about proving this algebraically and by contradiction. So we say $x^2+y^2 = pz$ and have to show this is impossible. Biblatex citation order I'm facing a problem with biblatex citation order.
