I am attempting to set up an nmake makefile to export our balsamiq mockup files to png files automatically, but I'm afraid I can't make heads nor tails of how to make a generic rule for doing so, without explicitly listing all the files I want exported.  details the command line syntax for exporting the files, and  contains an example which looks like it contains a generic rule for .obj files to .exe files. The makefile I have tried so far looks like this: .bmml.png:     &quot;C:\Program Files\Balsamiq Mockups\Balsamiq Mockups.exe&quot; export $&lt; $@  But this doesn't work. If I simply run nmake (with some outdated png files), nmake just does this: [C:\Temp] :nmake  Microsoft (R) Program Maintenance Utility Version 9.00.30729.01 Copyright (C) Microsoft Corporation.  All rights reserved.   [C:\Temp] :  If I ask it to build one specific file, it does this: [C:\Temp] :nmake &quot;TestFile.png&quot;  Microsoft (R) Program Maintenance Utility Version 9.00.30729.01 Copyright (C) Microsoft Corporation.  All rights reserved.  NMAKE : fatal error U1073: don't know how to make '&quot;TestFile.png&quot;' Stop.  [C:\Temp] :  Any nmake gurus out there that can set me straight? An example makefile which simply makes .dat files from .txt files by copying them, to experiment with, looks like this: .txt.dat:     copy $&lt; $@  this does nothing as well, so clearly I'm not understanding how such generic rules work. Do I need to specify a goal above that somehow lists the files I want?

How to import a jar in Eclipse I would like to highlight specific digits in a number. Since the number is large I would like to use \num{} from . Of course I can do it manually as in the MWE below, but was hoping that there might be an easy way to use the commented out syntax to accomplish this:  Code: \documentclass{article} \usepackage{xcolor} \usepackage{siunitx}  \newcommand*{\Color}[2][red]{\textcolor{#1}{#2}}%  \begin{document}  \num{99 976}  88\,9\Color{76} %\num{88 9\Color{76}}  77\,\Color{976} %\num{77 \Color{976}}  \end{document} Why do I get "Cannot redirect after HTTP headers have been sent" when I call Response.Redirect()? When I call Response.Redirect(someUrl) I get the following HttpException:     Cannot redirect after HTTP headers have been sent.   Why do I get this? And how can I fix this issue?

Looking for a good way to backup all my apps including their data,  refers to adb backup and adb restore. In several places one can find ways to remotely do on an Android device with the use of , such as transferring files using adb push or adb pull, accessing the  via adb shell, and more. So ADB seems to be a good thing to have for an Android user.  But how to get this "ADB thingy" on my computer? Not being a developer, installing the entire  seems a bit overkill. Is there a more minimalistic approach available? I understand that people explain (in layman's terms at least) that the presence of mass "warps" space-time geometry, and this causes gravity. I have also of course heard the analogy of a blanket or trampoline bending under an object, which causes other objects to come together, but I always thought this was a hopelessly circular explanation because the blanket only bends because of "real" gravity pulling the object down and then pulling the other objects down the sloped blanket. In other words, to me, it seems that curved space wouldn't have any actual effect on objects unless there's already another force present.   So how is curved space-time itself actually capable of exerting a force (without some source of a fourth-dimensional force)?  I apologize for my ignorance in advance, and a purely mathematical explanation will probably go over my head, but if it's required I'll do my best to understand.

The proprietary NVIDIA drivers "disappeared" with my latest update:    The option of "Proprietary drivers for devices" is correctly set under the "Ubuntu Software" tab. I have the graphics-driver PPA (ppa:graphics-drivers/ppa) correctly added to my sources.  Any ideas on how to bring the proprietary drivers back?

Disk space usage doesn't add up with df & du For which $f,g \in k[t]$, $k[f,g]$ is integrally closed? Let $f,g \in k[t]$, $k$ is a field of characteristic zero, $\deg(f)=n \geq 2$, $\deg(g)=m \geq 2$.     Is it possible to characterize all such $f$ and $g$ for which $k[f,g]$ is integrally closed in its field of fractions $k(f,g)$?   I do not mind to further assume that $k(f,g)=k(t)$ (but I do not want to assume that $k[f,g]=k[t]$, which makes my question trivial).  Thank you very much!  Edit: (i)  is relevant.  (ii) If also $k(f,g)=k(t)$, then being integrally closed is equivalent to $k[f,g]=k[t]$. Indeed: (a) If $k[f,g]=k[t]$ then $k[f,g]$ is integrally closed (since $k[t]$ is). (b) If $k[f,g]$ is integrally closed then, in particular, since $t \in k(t)=k(f,g)$ (= the field of fractions of $k[f,g]$) and obviously $t$ is integral over $k[f,g]$ (for example, $t$ is a root of $f(T)-f \in k[f,g][T]$) hence $t \in k[f,g]$, so $k[f,g]=k[t]$.  For example: $f(t)=t^2+1$, $g(t)=t^3-4t$. We have, $t= \frac{t(t^2-4)}{t^2+1-5}=\frac{g}{f-5}$, so $k(f,g)=k(t)$. By Abhyankar-Moh-Suzuki theorem, $k[f,g] \neq k[t]$, so $k[f,g]$ is not integrally closed. Similarly, for every $f,g$ such that $k(f,g)=k(t)$ and one of the degrees does not divides the other, then $k[f,g]$ is not integrally closed.  (iii) If also $k(f,g)=k(t)$ and $k$ is algebraically closed, then being integrally closed is equivalent to $H(t)=(f(t),g(t))$ is injective and $H'(t)=(f'(t),g'(t)) \neq (0,0)$ for every $t \in k$. Indeed, $k[f,g]=k[t]$ is equivalent to the new conditions (it is important that $k$ is algebraically closed!!).  Edit: What if we replace $k$ by an integral domain $D$ (which is a $k$-algebra)?

So I'm trying to install Visual Studio 2015 Community on my Windows Server 2012 R2 box which will end up being a Jenkins build server. Attempting to do so gives an error saying that I need to install KB 2919355.    So I attempt to download the right KB from the . The two files that I would assume to work are either Windows8.1-KB2919355-x64.msu and Windows8.1-KB2919355-x86.msu (just to try) and neither update work, saying that the update is not applicable.    I've not been able to get this working and I haven't been able to find a proper way to fix this. Can anyone offer any suggestions or solutions? Thanks! Hypernym for "audiobook", "podcast", "speech", etc.? Return more than 2000 records (SOQL) I'm trying to retrieve a list of Account objects from Salesforce using SOQL. Originally my query was this:  var result = service.query("SELECT Id, Name, RecordTypeId FROM Account"); return result.records.Select(record =&gt; record as Account).ToList();   However this only returns a maximum of 2,000 records and I have over that which I need to be returned by this query. After some digging around I found an example in Java which loops over the SOQL query which will allow a maximum of 10,000 records to be returned. I tried to replicate this in C# but it differs slightly, here is what I have now:  var accounts = new List&lt;Account&gt;(); foreach (Account account in service.query("SELECT Id, Name, Composer_ID__c, RecordTypeId FROM Account").records)     accounts.Add(account);  return accounts;   However this still only returns a maximum of 2,000 records. How can I return more than 2,000 records by querying Account?
