Trying to run Simplify Polygon (Cartography -> Generalization) tool in ArcGIS 10.2 (ArcInfo License).    I ran the tool successfully once, then tried again on a new polygon, but the simplification tolerance value field is missing...so running the tool results in an error that the missing value is required.    I tried restarting ArcMap but the field is still missing.    Is this a bug in the software or has anyone else had a similar experience?
I am having a strange problem in ArcGIS Toolbox.  I am trying to use the  tool from ArcToolbox. When I open the tool, there is no possibility to input Simplification Tolerance. Please see the attached image.  I can run the tool as a batch and from the Python window without any problem.  I am using ArcGIS 10(Editor) with Service Pack 5 on Windows 7 64Bit (English) and Windows Server 2008 64Bit (German). On both machines, I have the same problem. Any ideas?    I have reinstalled the software but the problem remains.
Labeling all sides of the matrix with kbordermatrix I have a matrix with labels on the left and top. Now I want to have a label on all sides of the matrix.

I've seen this done in Borland's  environment, but I'm not sure how to go about it for a C# application I'm working on. Are there best practices or gotchas to look out for? Recently a few friends and I came up with an idea for an app. To facilitate the creation of it, we set up LAMP on an Ubuntu Server 12.04. This box is running from my home. We've set up 3 user accounts. I'm still pretty new to Linux, but I have a bit of experience from using Ubuntu on my own box.  Today I was playing around with SSH and looking at the logs (I need to learn how to read that information to know how the server is performing, right?) and I saw the strangest thing.  In /var/log/auth.log and /var/log/auth.log.1 I saw a bunch of failed login attempts for 'root' and a few usernames I'm not familiar with. I looked over them and for as far as I can see no user has been authenticated except for the actual users on the system. A lot of the IP-addresses listed seem to be from Russia.  As of now this server contains nothing but a vanilla Ubuntu Server with LAMP, but even so, with the following command:  sudo grep -i fail /var/log/auth.log | wc -l   I get 3412 as a result. This seems very excessive for a server that has been up since April 8th. It gets worse, because running the above command on auth.log.1 returns 23075 (!!!!) results.  It seems obvious that people are trying to break into the server. Not that it contains anything of value, but once we start making progress on the app we wouldn't want our intellectual property stolen.  Should I be worried? And what can I do about it?  EDIT:  I found some very useful information  and this allowed me to run a script that splits and sorts all the invalid passwords and invalid users that tried to log in. May come in handy to someone who ended up here through Google! What's the derivative of: $ \sqrt{x+\sqrt{{x}+\sqrt{x+\cdots}}}$? let $ y=\displaystyle \sqrt{x+\sqrt{{x}+\sqrt{x+\cdots}}}$, i'm really interesting to know how do I find :  $\displaystyle \frac{dy}{dx}$ ?.  Note: I have used the definition of derivative of the square root function but i don't succed .

I'd like to create a chart where the column titles are rotated, as per this toy example:    I used the rotating package to generate the above. It has certain shortcomings: the rotate command doesn't leave space for the titles, so I have to manually space things to prevent overlaps. The turn command, by contrast, creates too much space, where each column is the width of the entire rotated column title.  There is also no easy way to have long titles be split into multiple lines.  Is there a package for creating tables of this sort, or at least one that would relieve some of the manual placing and spacing that goes into creating such a table?    This question is more to make sure I don't miss any easy way of doing what I want than seeking help on manually doing it, but the code for above is included anyways:  \begin{tabular}{r|ccc} &amp; \begin{rotate}{60} Property 1 \end{rotate} &amp; \begin{rotate}{60} Property 2 \end{rotate} &amp; \begin{rotate}{60} Property 3 \end{rotate} \\ \hline System 1        &amp;       &amp;       &amp;  X    \\  System 2        &amp; X     &amp; X     &amp;  X    \\ System 3        &amp; X &amp;   &amp;  X    \\ \hline \end{tabular} I am a Indian citizen in the United States on a F-1 visa.  For the summer break, I am traveling (round-trip) from Chicago to New Delhi via Dusseldorf-Frankfurt by Lufthansa airlines. My onward Journey would be on July - 8 and return Journey on Aug - 11.  My layover will be of 1 hour 10 mins in Frankfurt and 3 hours in Dusseldorf.  I would like to know if I require Category A or Category B Visa. If not, what type of visa do I require for the Schengen visa for my transit. How I can apply for the same?  I tried to find slots in German consulate but all slots are full before my departure date. If I don't get the Schengen visa, I cannot travel and will loose all the fare (since my ticket is a non-refundable ticket). Is there any other way I can tackle this situation. I have a large set of pictures, and I want to apply predefined settings to each using the optional argument of the \includegraphics macro from the graphicx package.  I would like to define the settings once at the top of the file (like \def\settings{width=\textwidth, angle=90}), and then apply them to all of my images so that I can modify all of the settings from one place.  If I run the following code block, it gives me the versions of the error "Package xkeyval Error: 'width=\textwidth, angle=90' undefined in families 'Gin'", which seems to be because it's interpreting my entire group of settings as a single key input.  \documentclass{article} \usepackage{graphix} \begin{document}      \def\settingsA{width=\textwidth, angle=90}     \def\settingsB{page=1, scale=.1}     \def\settingsC{angle=90, scale=.5}      \begin{figure}         \includegraphics[\settingsA]{filename1.png}         \label{fig:oneofonehundred}     \end{figure}      \begin{figure}         \includegraphics[\settingsB]{filename2.pdf}         \label{fig:twoofonehundred}     \end{figure}      \begin{figure}         \includegraphics[\settingsC]{filename3.jpg}         \label{fig:threeofonehundred}     \end{figure}   \end{document}   What is the technique to modify this settings string so that it is interpreted correctly? How do I pass an optional argument that is interpreted as a set of arguments instead of one string?  Thanks in advance! Consider the following sentences:        I'll move to the south by then probably.   I'll probably move to the south by then.   I'll move to the south probably by then.      Which of the three is correct. In my opinion, the third one is wrong. First two are correct with a small difference in their meaning.  First one makes my probability refer to the time when I'll be moving and the second one tells that there is still a chance that I might not move.  Am I correct? Why do newspaper headlines use strange syntax rules? Newspaper/news article headlines usually have different syntax rules, for example   No copula. North Korea trip 'successful' Past events written in present. Qantas cancels flight out of frozen Heathrow Predictions written with infinitive. Britain's 'crossbow cannibal' to die in jail Very often not in complete sentence. No indefinite/definite articles. Ivory Coast Faction Squeezes UN Force Using a comma instead of "and". Romania, Bulgaria face delay in joining Schengen.   Why these rules and are there any other rules? How do I ensure that figures appear in the section they're associated with? Often floats may land quite a bit later in the document than the point they are created, sometimes after a section break.  Is there a way to force a new section to start on a new page, after any unplaced floats? What do they do with all the plates and cups in Star Trek? Whenever someone in Star Trek creates food or drink in the replicator it is generated in the bowl, plate, or cup. It seems like after a few months they would have piles of used dishes from replicator food while making more for every meal. What do they do with all the dishes? Why does everyone do 9-overlord, not 10-overlord? What is the advantage on saving the money for the overlord when you have 9 drones, and not filling your supply first and then getting the overlord?  In my theory, in the first case you get to wait the saving time with 9 drones, and get to wait almost the same time with 10 drones in the second case. Second case should be better, since 10 drones mine faster than 9? So why does everybody go with the first case?  All this is assuming you go 12 pool or something like that, where you will get more drones after the overlord. 6- and 8-pools are obviously different. Which one is the formula of angular velocity? Is it $\omega= vr$? If not then why does the source below use $mvr=nh/2\pi$, where $mvr$ is angular momentum and $vr$ is angular velocity? Again $\omega=v/r$ shows radian per second. I saw $\omega= vr$ in one book and $\omega= v/r$ in another! How to print fields value in views-view.html.twig in drupal 8 How to print fields value in views-view.html.twig I have created a views-view.html.twig file for my view slider_3. The template name is 'views-view--slider_3.html.twig' The view formatting is done by this template, but I need a field is come at begging position of the view:  &lt;div class="slider-3-main"&gt;{{ rows.required_field }} &lt;div{{ attributes.addClass(classes) }}&gt;   {{ title_prefix }}   {% if title %}     {{ title }}   {% endif %}   {{ title_suffix }}    How can be the field will written to display at {{ rows.required_field }} Define $\mathcal N$  $\mathcal N (A):=\mathcal P(A)\setminus\{\varnothing\}$  Does $\mathcal N$ has a special name and standard notation? Call to a member function on a non-object So I'm refactoring my code to implement more OOP.  I set up a class to hold page attributes.  class PageAtrributes  {   private $db_connection;   private $page_title;      public function __construct($db_connection)      {         $this-&gt;db_connection = $db_connection;         $this-&gt;page_title = '';     }      public function get_page_title()     {         return $this-&gt;page_title;     }      public function set_page_title($page_title)     {         $this-&gt;page_title = $page_title;     } }   Later on I call the set_page_title() function like so  function page_properties($objPortal) {         $objPage-&gt;set_page_title($myrow['title']); }   When I do I receive the error message:     Call to a member function set_page_title() on a non-object   So what am I missing?
