is there any possibility to use an Esri .lyr data in QGIS?   Maybe a tool to convert the file into a xml or sld?
At college we use ArcGIS Desktop 10, but that does not function on my Mac so I have QGIS there instead.  I want to do my exercises with QGIS, but in ArcGIS Desktop we use .lyr files with ArcMap and .lyrx files with ArcGIS Pro, and they are not supported by QGIS.  Does anyone know, how I can connect the *.lyr files to my *.shp files to use them on my Mac with QGIS?
What does the `who` command result `root :0` mean? The return value of command who will always include root :0 in X Window pts. I guess it actually means the GNOME login. Am I right?  Another question is where to get this knowledge, as I don't see it in the man who, neither in info who.  Example  [root@localhost root]# who root     :0           Sep 11 06:33  root     pts/0        Sep 11 06:36     (:0.0) Determining if a game is CPU- or GPU-limited What is a reliable, but not too time-consuming way to determine if a certain game is limited by the graphics card or by the processor speed?  I have some preconceptions about whether I'm mostly GPU or CPU limited, but I'd like to verify if I'm right about that. I have some ideas how I would go around and test that but performing accurate benchmarks is notoriously tricky and I don't have much experience with it.   So I'm wondering what would be an easy way to determine the bottleneck, having only one computer with a certain configuration available? What tools would I use for that purpose?  It would also be interesting to determine if the amount of VRAM on my graphics card is a limiting factor. What is some good free software for doing physics calculations?  I'm mainly interested in symbolic computation (something like Mathematica, but free). "Repository doesn't support architecture" when trying to update on Landscape client Redirect STDERR and STDOUT to different variables without temporary files func() {     echo 'hello'     echo 'This is an error' &gt;&amp;2 }  a=$(func) b=???   I'd like to redirect the stderr to b variable without creating a temporary file.   echo $b  # output should be: "This is an error"   The solution that works but with a temporary file:  touch temp.txt exec 3&lt; temp.txt a=$(func 2&gt; temp.txt); cat &lt;&amp;3 rm temp.txt   So the question is, how do I redirect the stderr of the  function func to the variable b without the need of a temporary file? Split a string with delimiters but keep the delimiters in the result in C# Primary filegroup is full SQL Server 2008 customize of autoref The interaction of TeX and Lua can be quite delicate at times.  While the former has category codes and tokens, the latter has escape sequences and datatypes.  Mixing the disparate concepts of these two worlds can lead to unexpected behaviour which favours common errors, known as gotchas. In the community wiki answer below you can find an overview of the common mistakes that people make when getting to grips with LuaTeX. Windows 10 puts my first and last name to lock screen. How to avoid this? After upgrading to Windows 10, I see my LastName and FirstName on the lock screen. Is there a way to change this? On Windows 8.1 there was just my nickname and email address (maybe there were my first name and last name, but not displayed so large as they are now).  I mean the name and surname parameters specified in my Microsoft account.  Another question: I prefer the format FirstName LastName, not vice versa.  Is there any way to change this as well?   Apart from Lock Screen I see it on the Start Menu. Cleric build to maximize melee damage and spell healing "(CRON) info (No MTA installed, discarding output)" error in the syslog Automatically show which tags were edited in revision history I’ve developed the habit of using the revision summary to indicate which changes I’ve made to the tags while retagging a question.  For instance, if the question originally had tags   and it should be  instead, I write the following in the revision summary:     Edited tags: -cocoa, -touch, +cocoa-touch   which I find useful (and potentially educational) for the OP and other editors.  On the other hand, when an editor doesn’t type a revision summary, Stack Overflow shows     User (timestamp) edited tags   with no indication of the difference between previous tags and the tags set by that edit.  Since there’s a limit on the number of tags, this difference would easily fit in the revision history list of that question. Could this be automatic in case the editor doesn’t fill the revision summary? Is it worth it? Executing user-supplied ruby code on a web server Is casting the same thing as converting? In Jesse Liberty's Learning C# book, he says "Objects of one type can be converted into objects of another type. This is called casting."  If you investigate the IL generated from the code below, you can clearly see that the casted assignment isn't doing the same thing as the converted assignment. In the former, you can see the boxing/unboxing occurring; in the latter you can see a call to a convert method.   I know in the end it may be just a silly  semantic difference--but is casting just another word for converting. I don't mean to be snarky, but I'm not interested in anyone's gut feeling on this--opinions don't count here! Can anyone point to a definitive reference that confirms or denies if casting and converting are the same thing?      object x;     int y;      x = 4;      y = ( int )x;      y = Convert.ToInt32( x );   Thank you  rp  Note added after Matt's comment about explicit/implicit:  I don't think implicit/explicit is the difference. In the code I posted, the change is explicit in both cases. An implicit conversion is what occurs when you assign a short to an int.  Note to Sklivvz:  I wanted confirmation that my suspicion of the looseness of Jesse Liberty's (otherwise usually lucid and clear) language was correct. I thought that Jesse Liberty was being a little loose with his language. I understand that casting is routed in object hierarchy--i.e., you can't cast from an integer to a string but you could cast from custom exception derived from System.Exception to a System.Exception.   It's interesting, though, that when you do try to cast from an int to a string the compiler tells you that it couldn't "convert" the value. Maybe Jesse is more correct than I thought! Prove $\chi(G)\chi(\bar{G}) \geq n$ for chromatic number of graph and its complement Give me a blank Comment box when I am Improving a Suggested Edit The suggested edit screen includes both the suggested edit, and the reason for the edit:        When you click to improve the edit, that comment is left as-is and hidden at the bottom of the post above the save edit button:        At the moment, when I Improve a Suggested Edit, the Comment text for that Edit is retained (though editable). It's unlikely that the comment would still apply (e.g. Suggester added a tag and Approver corrected a typo), so I would rather have the field blank.  Also, it's better to have a blank Comment than an incorrect one... many people don't bother changing the original Comment.  So that box should be blank like this instead: Efficiently selecting a set of random elements from a linked list Construct a Borel set on R such that it intersect every open interval with non-zero non-"full" measure This is from problem $8$, Chapter II of Rudin's Real and Complex Analysis.  The problem asks for a Borel set $M$ on $R$, such that for any interval $I$, $M \cap I$ has measure greater than $0$ and less than $m(I)$.  I was thinking of taking the Cantor approach: taking $R$ to be the union of $[a,b]$ with $a$ and $b$ rationals, and for each $[a,b]$ we construct Cantor sets inside it. During theconstruction of each Cantor set, in order to have positive measure on it, we need to take off smaller and smaller intervals from it, namely the proportion goes to $0$. As a result, these Cantor sets are extremely "dense" on their ends. If for an interval $I$ it intersects with the Cantor set on $[a,b]$ while $b-a&gt;&gt;m(I)$, we shall expect the measure of intersection to be rather close to $m(I)$ and then we lose control on these cases.  Is there any way to fix this or shall I consider other approaches?  Thank you How to rename wp-includes folder? Is there a way that we could rename wp-includes folder   I have found out there are ways to do for other folders. But how do we do it for wp-includes folder?
