I have a multi feature shapefile and a slope raster and I'm trying to export images (tif, png whatever) for each feature showing the feature boundary and the slope raster contained within it with a field from the shapefile as the filename. I am dealing with a lot of features (&gt;100,000) so efficiency is key, I tried data driven pages and it failed every time.
I have a raster aerial photo.  I have county wide parcel data.  I want to clip/screen shot the raster at each individual parcel.  Think of this application - a post card with an image of your house --here is your house--  I want to have each parcel attribute to contain information + hyperlink of the aerial photo.  Any other solutions welcome, but this is the only method I could think of. Although I am unsure of how to achieve it efficiently.  Using ArcInfo 10.
I am currently working my way through "A Concise Introduction to Pure Mathematics" by Martin Liebeck, and have been stuck on an excersise for a couple of days now. The question reads:  "Show that for an integer n $\geq2$, the period of the decimal expression for the rational number $\frac{1}{n}$ is at most $n-1$."  I've been trying to solve this without making any substantial progress. And yes, I have seen explanations that when performing a long division the decimal expression either terminates to $0$ or eventually repeats. But I haven't seen any proof of this that I've been satisfied with, even less do I know how to formalise this type of proof. I've tried to write out long division with arbitrary digits, but that obviously turns out to be too much of a hassle and basically impossible to draw any conclusions from. What are bitwise shift (bit-shift) operators and how do they work? I've been attempting to learn C in my spare time, and other languages (C#, Java, etc.) have the same concept (and often the same operators) ...   What I'm wondering is, at a core level, what does bit-shifting (&lt;&lt;, &gt;&gt;, &gt;&gt;&gt;) do, what problems can it help solve, and what gotchas lurk around the bend? In other words, an absolute beginner's guide to bit shifting in all its goodness. Custom URL Hack - anybody know how can i find the fields IDs from "User" object? I'm new in custom URL hacking.  I am trying to write a custom URL in a custom button. It is suppose to clone the User record, and while doing so, I want some user fields to be cleared. However, I need help identifying those fields IDs (e.g. Email, Name, etc).  How can i refer these fields when writing the custom URL code? Prove that   $\dfrac {\left( 5^{125}-1\right)}{\left( 5^{25}-1\right)}$ is composite number using number theory. Do not use calculator or Wolfram alpha or anything like that. How to execute a program or call a system command from Python How do you call an external command (as if I'd typed it at the Unix shell or Windows command prompt) from within a Python script? Show $\sum\limits_{n=0}^{\infty}{2n \choose n}x^n=(1-4x)^{-1/2}$ How do you prove that $\sum\limits_{n=0}^{\infty}{2n \choose n}x^n=(1-4x)^{-1/2}$? I tried to identify the sum as a binomial series, but the $4$ and the $-1/2$ puzzle me. (This series arises in studying the first passage time of a simple random walk.) Narrow-phase collision detection algorithms "like I" or "like me"? In high school we learned to say "than I" and "as I" because you could potentially add an "am" to the end of the sentence.  Examples:  "She is smarter than I."  (Think: "...than I am.") "He is as tall as I."  (Think "...as I am.")  So analogously, shouldn't it be "like I" as well:  "He is sincere, just like I."  (Think: "... like I am.")  But universally, it seems that we use "like me".  Where does this reasoning break down?  Is there history here? How to restrict some websites in Ubuntu 14.04 I would like to restrict some websites to be surfed. I mean I want to prevent access to some websites. Please guide me on how to do the same in Ubuntu 14.04 LTS. Does $\sum_{m=1}^{\infty}\sum_{n=1}^{\infty}a_{mn}^3=\sum_{n=1}^{\infty}\sum_{m=1}^{\infty}a_{mn}^3$ occur here? Let $\{a_{mn}\},~m,n \in \Bbb{N}$, be an arbitrary double sequence of real numbers then does the following equality occur always?   $$\sum_{m=1}^{\infty}\sum_{n=1}^{\infty}a_{mn}^3=\sum_{n=1}^{\infty}\sum_{m=1}^{\infty}a_{mn}^3$$   I think there is no reason for the equality of this iterated series in general but I cannot figure out how to construct a counter example. Can anyone please help me how to create a example of $\{a_{mn}\}$ such that the given equality does not hold...!! "I am going to have a walk" My teacher said "I am going to have a walk" today in class and to me it seems incorrect. Correct variants that I know are:    Going for a walk Going to take a walk Going to walk  ...   Is this correct? If so, why? I have 2 equation in terms of $a,b$ and $c$ .  $3a + 10b + 5c =0$ and $4a + 6b + 2c =0$  I need to find a:b:c and answer is $\dfrac a5 = \dfrac {b}{-7} = \dfrac {c}{11}$  I want to know how to get that?  My attempt:  Given equations can be written in form   $$\left ( \begin{matrix}           3 &amp; 10 &amp; 5 \\           4 &amp; 6 &amp;  2 \\           \end{matrix} \right )  \left ( \begin{matrix}           a\\         b\\         c\\         \end{matrix} \right ) =  \left ( \begin{matrix}            0 \\          0\\         \end{matrix} \right ) $$  But here I don't have any idea how to proceed. I can do for 3×3 matrix and I thought it can be done in same way.  Thanks.

How to boot from non-Ubuntu live ISO images like Fedora or CentOS? High CPU usage by "System" and "System interrupts" (caused by ACPI.sys) I have a laptop, which was running Windows 8.1 x64 without any problems. Now with Windows 10 x64 installed, Task Manager constantly shows unusual CPU usage by "System" and "System interrupts". To solve this, I already tried the following, without success:   Disabling and uninstalling all non-essential drivers. Installing newer drivers than the ones that were automagically installed (if available). Disabling/enabling fast boot option. Disabling all of the non-essential services. Sysprep. Resetting BIOS to defaults and various combinations of settings. Flashing BIOS to the latest available version. Clean install from the same media that I use for other PCs. Installing all of the updates offered in Windows Update to this day. Windows Performance Recorder / Analyzer.   I'm not very familiar with Windows Performance Analyzer, so I'm hoping someone here can point me in the right direction - what exactly should I look for, to figure out which device/driver is the culprit. Or, if there's any other approach to figuring out this problem?  For the brave souls, here's my  and a screenshot of the problem: I can't seem to get this hat on straight!

Notify close voters when a closed question gets edited As mentioned in , a question closed because it was not well-phrased is currently very unlikely to be reopened after an edit clarifying the issues. Those who voted to close should at least be asked to reconsider and reopen the question after such an edit. Calculating $\lim_{x\to0} \left\lfloor\frac{x^2}{\sin x \tan x}\right\rfloor$ Find $$\lim_{x\to0}  \left\lfloor\frac{x^2}{\sin x \tan x}\right\rfloor$$ where $\lfloor\cdot\rfloor$ is greatest integer function   I am a high school teacher. One of my students came up to ask this limit.  For $\lfloor\frac{\sin x}{x}\rfloor$, I have used $\sin x &gt; x$ using increasing decreasing functions.  I tried to prove $x^2 &gt; \sin x \tan x$ using increasing /decreasing  function but I am not getting it. Is there a Ubuntu sanity check? Is there a standard procedure to 'unit test' an Ubuntu system against the deb packages?  Assume, a system has ubuntu-desktop installed according to the package manager. Can I find out, whether the file system has all the files in ubuntu-desktop and dependencies?   related question:
