I am using Ubuntu 12.04, TexLive 2012 from backports, TexLive full installation.  However, when I try to compile via latexmk, I get an error message that biber is missing.  How to get biber working on 12.04 - but please only with packages from the repository, not with manual installation.
I am getting really confused now. I installed Tex Live 2012 on my Xubuntu 12.04 with a backport and I installed TexMaker.  I could user PdfLatex right away and it generated everything I needed except my bibliography. I read that Tex Live 2012 comes with biblatex so I just changed the bibtex command in TexMaker from "bibtex" to "biblatex". However, that does not exist. So I did  sudo apt-get remove biblatex sudo apt-get install biblatex   The package is installed but I don't find the binary. Using bibtex the whole thing crashes. Which does not surprise me since I want to userbiber:  \usepackage[backend=biber]{biblatex}   Btw does biber come with biblatex? So far I couldn't get any clear explanation what biber and biblatex are to each other.  EDIT: I had to remove texlive completely and install it with the install script form . Apparently the newest version of biber does not work with the older version of biblatex I had.
When to use single quotes, double quotes, and backticks in MySQL I don't understand at all why:  \begin{equation} \sum\limits_{n=0}^\infty p_n x^n = \prod\limits_{k=1}^\infty (1-x^k)^{-1} \end{equation}  Where $p_n$ is the number of partitions of $n$. Specifically how can the sum of positive numbers ever be factored into a fraction or factors to the $-1$ power? Is this something purely notational or am I missing something big?  Thanks for all the help! My website is javatechig.com and is around 6 months old. I have used All-in-One SEO WordPress plugin for SEO tricks. Definitely after using SEO plugin, my website page view is increased, but still it is not giving one good site-link in Google Search.   I have followed the following steps:   Created sitemap.xml and submitted to Google Webmaster Tools Edited all posts with meta tags Header tags are carefully taken care   I want to make a sitelink similar to the attached image: Nautilus context menu for current directory when there's lots of files / "Open in Terminal" Constructing a function that is continuous and has a max on an open interval, but is not necessarily increasing immediately to the left of the max. I washed and dried my passport by mistake, do I need a new one? Around two years ago I washed and dried my passport by mistake at the laundry room. My ID, my old US student visa and my stamps from european countries are still readable but the pages are not "flat" anymore and the front cover is kind of erasing (some parts of the Brazil symbol is gone).   In April I'll travel to US for a conference, I'll need to get a new US visa (B1/tourism visa) but I'm worried if my passport is not "good to go" anymore because it was "washed and dried". Apparently there is an electronic chip in it and I don't know if it is still working.  Should I get a new passport or can I save some money and time and use this one? It expires only in 2019. Solutions to $a+b+c=12$, $a, b, c \in \mathbb{N}_0$ Let $a, b, c \in \mathbb{N}_0$. If $a+b+c=12$, how many solutions $(a,b,c)$ satisfy the equation?   Is the answer:      $729$ How does \fontsize{}{} work? With the package anyfontsize I can use the command \fontsize{}{}. But the second argument seems to be without any effect. I read  that it is related to the line space. It doesn't work.  \documentclass{article} \usepackage{anyfontsize} \begin{document}  {\fontsize{1cm}{1cm}\selectfont First test : I need to put some text here.}  \bigskip  {\fontsize{1cm}{2cm}\selectfont Second test : I need to put some text here --- does it work?}  \end{document}     Any clue? When an air-filled balloon is released without its opening tied up, it moves in a circular path rather than a straight line. Why is that? Ambiguity in Negation: "John did not come because of the rain" I am working on SharePoint 2010, I have a custom list with columns Start date , End date, Created by, Approval Status. I have created a page where I am looking to filter the list and show the result depending on the approval status which is a column in custom list as shown in figure . Can some one help me out on how to approach for this. When I post an answer to a brand new question I usually find that someone else has submitted that same answer just moments before. (, usually ;-) )  What I've started to do lately is (I think) the right thing.   If I notice that another answer predates mine, and that I add no value over it, I immediately delete my own answer, and upvote the other guy.  I recommend that you too do the same. Otherwise the message will be diluted.  Similarly, if after posting your "answer" you realise that you are in fact wrong (and you've just misread the question) -- you can actually delete your answer.  Is this reasonable?  (The reason why I'm writing this down is because it feels completely counter-intuitive to delete your own stuff. But it really saves everyone time and effort) Few days back while attending a thesis defense, one Professor was asking the defender why does he think, he deserves the degree. I was wondering since then, is there really any general answer for that? or the answer should be given describing my own work and then emphasis them how it is important for research field?  I asked the question here to know your opinion about it and to list down what could be the possible answers to this question. Specific derivatives have specific names. First order is often called tangency/velocity, second order is curvature/acceleration. I've also come across words like Jerk, Yank, Jounce, Jolt, Surge and Lurch for 3rd and 4th order derivatives. Is there a widely agreed list of names for these? How many orders have specific names?  In this case, I'm dealing with NURBs curves, so the "tangency" and "curvature" related words are to be preferred over "velocity" and "acceleration" words. Where do I get the key for the first house? I've 'completed' the game, but didn't find the key for the first house. (I got the one for the arcade machine house). Where can I find it? I need to conduct a performance test on Azure website and the Users count is '200000'. Can anyone suggest me the configuration for this? I'm using BibLaTeX to handle my bibliography and I want a reference to be placed in a footnote on every page where I cite the same work and have the same number. Also I want to be able to cite the same work on one page several times. The latter could be done by using  from the Joseph Wright's blog. However, it puts a reference in a footnote only once. I have multiple Ubuntu machines at home and a pretty slow internet connection, and sometimes multiple machines need to be updated at once (especially during new Ubuntu releases.)  Is there a way where only one of my machines needs to download the packages, and the other machines can use the first machine to get the debs?  Does it involve setting up my own local mirror?  Or a proxy server?  Or can it be made simpler? Solving functional differential equation $f'(x)=2f(2x)-f(x)$ Show that there is at least a nonzero function $f$, differentiable on $[0,+\infty)$, satisfying $$f'(x)=2f(2x)-f(x) \qquad \forall x&gt;0 $$   $$M_n:=\int_{0}^{\infty}x^nf(x)dx&lt;\infty \qquad \forall n\in  \mathbb{N} $$   My best idea so far is to assume that the solution is a power series, i.e.  $$ f(x)=\sum_{n=0}^{\infty}a_nx^n\qquad \forall x&gt;0$$ Then the equation becomes $$ \sum_{n=0}^{\infty}na_nx^{n-1}=2\sum_{n=0}^{\infty}a_n2^nx^n-\sum_{n=0}^{\infty}a_nx^n$$ equating all the coefficients of the same degree I get $$na_n=(2^{n}-1)a_{n-1}\qquad \forall n\geq 1$$ So setting $a_0=1$, I get $$a_{n}=\frac{1}{n!}\prod_{k=1}^{n}(2^k-1) \qquad \forall n$$ But does the power series actually converge? Using Hadamard's formula, and that $2^{k}-1\geq 2^{k-1}$, $$ |a_n|^{1/n}\geq\frac{1}{(n!)^{1/n}}\left[2^{n(n-1)/2}\right]^{1/n}\sim\frac{e}{n(2\pi n)^{1/2n}}2^{(n-1)/2}\to \infty$$ so the radius of converge of the series is $0$, so it doesn't actually define a solution on $[0,+\infty)$. How do I change my timezone to UTC/GMT? Currently when I execute the date command from bash I get the following displayed  Thu May 17 12:21:00 IST 2012  Below is my timezone config based on executing dpkg-reconfigure tzdata     Current default time zone: 'Europe/Dublin'   Local time is now: Thu May 17 12:32:52 IST 2012.   Universal Time is now: Thu May 17 11:32:52 UTC 2012.     Any idea how I change from IST to UTC/GMT?
