I am preparing a LaTeX beamer presentation. I want to have few frames with the blur effect on images to focus on different aspects at a time, just as in the image below.  I tried this by creating a semi-transparent (or low opacity) overlay that covers the entire image region and then keeping the image to focus on top of this (with full opacity). \begin{tikzpicture} \usetikzlibrary{shapes.geometric} \node[align=center, opacity=.1, text opacity=1] at (-2.8,1.5) {\includegraphics[scale=0.1]{img/test.png}\\ Text 1}; \node[align=center, opacity=.1, text opacity=1] at (0,2.5) {\includegraphics[scale=0.1]{img/test.png}\\ Text 2}; \node[align=center, opacity=.1, text opacity=1] at (2.8,1.5) {\includegraphics[scale=0.1]{img/test.png}\\ Text 3}; \node[align=center, opacity=.1, text opacity=1] at (-2.8,-1.5) {\includegraphics[scale=0.1]{img/test.png}\\ Text 4}; \node[align=center, opacity=.1, text opacity=1] at (0,-2.5) {\includegraphics[scale=0.1]{img/test.png}\\ Text 5}; \node[align=center, opacity=.1, text opacity=1] at (2.8,-1.5) {\includegraphics[scale=0.1]{img/test.png}\\ Text 6}; %Opac layer \node[rectangle,fill=black, opacity=0.1, text opacity=1,minimum width=6cm, minimum height=6cm] at (0,0) {}; \end{tikzpicture}  However, this does not create the desired blurred effect. Please suggest how I can achieve this using TikZ. (Image taken from .)
Partial or entire Image Blurring in TikZ?  I have seen some examples of drop shadow blurring in the pgf-blur package version 1.01 by Martin Giese but this isn’t what I mean.  Is it somehow possible to do partial or entire Image Blurring in TikZ, just like what one may do in Adobe Photoshop?
Is Lambert Academic Publishing a reputable company? I was contacted by the Acquisition editor of Lambert Academic Publishing (LAP) to publish my bachelor's thesis as a printed book. Is LAP any good? I have no idea about it; I have just heard that it's a freelance publishing house. How to use "who" vs. "that" A short story about finding an inhabitable planet and meeting aliens Is Site Traffic Data Gone for Good After Fixing Previous Bug? There was a previous bug affecting site traffic statistics showing -zero- for months (). This has been fixed in that it is now graphing the data.  It appears that previous data may be lost? The graphs below are from . I don't have access to any other sites' graphs to see if they are showing similar results. Consider $X = (a+b)^n-a^n-b^n$  where  $a$ and $b$ and $a+b$ are not divisible by $n$, $n&gt;=3$ is positive and prime, $a \ne b$ and both are greater than 1.  By the binomial expansion we know $X$ is divisible by $n$, but how can we study whether $X$ is divisible by $n^2$ or other powers of $n$? Specifically I am interested to prove $X$ is NOT divisible by $n^2$, but I am not sure how to prove or disprove it. Combinatorial Proof Question: Vandermonde convolution identity Wheel going badly out of true on final tightening On two occasions (same wheel, loosened everything off and re-did the whole thing after the first time) as I've applied a final half turn to tighten the spokes round the wheel it's gone from being pretty laterally true (within about 0.5 mm) to badly out of true (probably a couple of mm or more out).  The simplest explanation would be that I've managed to mess up by missing spokes/over under-tightening some of them, but I'm fairly sure that's not the case.  What else could cause this?  This is a rear wheel with a fair amount of dish. I'm worried that I might be over-tightening. On both occasions I decided to do a final half turn as the non drive side seemed a little loose, but I was concerned the drive side might be over tight. Could this cause a sudden change in trueness?  I've got the wheel back to a reasonable state, but I'm no longer sure I have even tension in the spokes. list files and store it in variables I'm new with shell programming. My goal is to give the user a selection which file should be run. I catch all available scripts in one var with:  var=$(find script*)   so far so good, this is the output:      echo $var     script1 script2 script3 scr...   now I want to store each file in a singel variable to run it in later selection  select SEL in script1 script2 script3 .......... case $SEL in         $Script1) echo ($Script1 will start) &amp;&amp; ./$script1 ;;         $Script2) echo ($Script2 will start) &amp;&amp; ./$script2 ;;         $Script3) echo ($Script3 will start) &amp;&amp; ./$script3 ;;         $Sc..) echo ($Scr.... will start) &amp;&amp; ./$scrip.... ;;         $Sc...) echo ($Sc...... will start) &amp;&amp; ./$scrip..... ;;         *) echo "choose on of the availabel files";;     esac done   I don't have a clue how should I should separate all files if I don't know how many and the exactly length of each file.  I tried to split with echo ${var[1]} and echo $var[1] but this dosn't work. I recive either a empty output or the whole string. Does Forbidden Island usually need any rule variants for playing with 5+ people? I don't see any reason why Forbidden Island wouldn't be able to handle 5 or maybe even 6 players with some simple variants. Does anyone have any experience with different player numbers with some wisdom to pass on?  It would be slightly harder to gather the required 4 treasure cards at one person, but there would be more people total to trade with. The island would sink faster and it would take longer for a certain critical player to have their turn, even though the navigator and helicopter can move anyone. How can these disadvantages be offset to keep the game strong and sufficiently difficult? What application launchers are available for Ubuntu? Adjusting space between array rows and columns \documentclass[english]{article} \usepackage[T1]{fontenc} \usepackage[latin9]{inputenc} \usepackage{babel} \begin{document} % ... \[ \begin{array}{ccccc} x(1) &amp; = &amp; \frac{x(0)}{1} &amp; = &amp; x(0)\\ x(2) &amp; = &amp; \frac{x(1)}{2} &amp; = &amp; \frac{x(0)}{2}\\ x(3) &amp; = &amp; \frac{x(2)}{3} &amp; = &amp; \frac{x(0)}{2.3}\\ x(4) &amp; = &amp; \frac{x(3)}{4} &amp; = &amp; \frac{x(0)}{4!}\\  &amp;  &amp;  &amp;  &amp; \vdots\\ x(n) &amp; = &amp; \frac{x(n-1)}{n} &amp; = &amp; \frac{x(0)}{n!} \end{array} \] % ... \end{document}   Because of the fractions in the array cells, array elements are vertically too close to each other, they are literally touching to each other. Also the horizontal spacing is too much as you see in the image (screen shot from the output PDF file).  How do I make these cell-spacings look better? I am looking to create realistic car movement using vectors lognormal distribution, standard-deviation and (physical) units I have a distribution of microparticles that follows a lognormal distribution. The cumulative distribution function thus is given by:  $$ F_X(x;\mu,\sigma) = \frac12 \operatorname{erfc}\!\left(-\frac{\ln x - \mu}{\sigma\sqrt{2}}\right) $$ $$ \mu = ln(M) + \sigma^2 $$  Now, the plot of the distribution function should be exactly the same no matter if the particle diameter $x$ is given in micrometers or meters (as long as I adapt the x-axis accordingly of course). However, this only works if I only convert $x$ and $M$, while not touching the numerical value of $\sigma$, and I don't understand why. $F_X$ has to be unitless, so $x$, $\mu$ and $\sigma$ should all have the same unit, right?

Inner product of two continuous maps is continuous Let f,g be continuous maps of S in $\mathbb{R}^n$, to $\mathbb{R}^m$. Show the inner product h(x) = $\langle f(x), g(x)\rangle$ is continuous.  My attempt: Since f,g are continuous, their product is a continuous mapping, so for $\epsilon \gt 0\: t.e\:  \delta \gt 0$ such that $\parallel x - a\parallel \lt \delta $ implies $\parallel \langle f(x),g(x)\rangle - \langle f(a)g(a)\rangle \parallel \le\parallel f(x)g(x) - f(a)g(a)\parallel \lt \epsilon$ by schwartz inequality. How can I automatically enable large text when logging in to the ubuntu session? How do I test a private function or a class that has private methods, fields or inner classes? It'd be nice to see reputation updates in the app, as we get on both the desktop and mobile sites.  Mock-up of how this would look:        Other possible icon states:        While I understand reputation is shown in the feed, it's a bit unwieldy, and has no notification.   With this feature implemented, the feed could arguably lose both reputation and inbox items, and be left with the interesting questions that fill it up. This would make for a much more consistent UX across app and desktop. I'm trying to identify a song by a female 80's pop group.
