  • Is null return path reliable indication of a bounce?

    - by Vasiliy Faronov
    I have a mailbox that receives bounces as well as normal email (the latter includes messages from automated services). I want to filter out the bounces and forward them to another mailbox. Assume I cannot change the envelope return path in email I send. Is “null return path” a reliable criterion to tell bounces from normal mail? Roughly how many false positives and false negatives can I expect if I apply it?

  • How to build a self-sufficient gcc/glibc/binutils set in a non-standard path?

    - by netvope
    Suppose a set of custom-built gcc/glibc/binutils are in $prefix (e.g. /home/user/path) I want: gcc to look for libraries in $prefix/lib64 instead of /lib64 gcc to look for headers in $prefix/include instead of /include to use $prefix/lib64/ld-linux-x86-64.so.2 as the (hard-coded) loader path instead of /lib64/ld-linux-x86-64.so.2 the dynamic loader to look for shared libraries in $prefix/lib64 instead of /lib64 How should I configure the builds? Do I need to modify gcc's specs file or do anything else?

  • OS X: How can I copy the shell path to clipboard?

    - by lexu
    When working with files on my mac I employ a mixed approach of shell/finder or keyboard/mouse, similar to working with 4NT and Explorer on Windows. One thing I use(d) extensively on Windows is to copy the path of the current directory to the clipboard. This is an extended feature of TakeCommand by JPSoft, on Windows. Is there a way to copy the current path from the bash shell to the mac's clipboard, so I can use it in 'file open' and/or similar dialogues?

  • Executable execution path. Does it depends of the place the executable is called from?

    - by Valkea
    as I'm still a new Linux user, I still discover some behaviours and I'm unable to tell if they are "normals" or not. I searched the Internet but as I can't really find an answer I guess it's time to ask here. Few weeks ago I installed a small game called "Machinarium" and I played it... but few days later when I wanted to continue my game I was unable to make the game start correctly. And as I didn't had the time to search I given up. But yesterday as I was working on a program of mine, I had the exactly same behaviour. So I searched a bit and I discovered that when using Nautilus with the "List view", I was able to run the program (ie: the program does find the sound, images etc resources) when I was literally "inside" the executable folder, but unable when I was in a parent folder and expanding it to the executable folder to run it. To illustrate the behaviour here are two screen shots. It doesn't works if the executable is double clicked from here It does works if the executable is double clicked from here This is indeed the same "place", but the Nautilus view is slightly different as the current folder is not the same and it seems to make a difference for the program. Furthermore, when I create a menu items via System Settings/Main Menu to the executable, it behaves just like if the executable can't find the resources (that's why I was unable to play Machinarium the second time as I created a menu short-cut after my first game). So I asked my program to generate a text file at it's root when running, and I started to launch it from different "parent" folders to see where is generated the text file. Each time the file was generated on the top folder of the current Nautilus view. I was expected to see it appears in the same folder of the executable (well not as I was guessing what as happening, but before that I would have expected to see it appears in the exe folder). Does anyone can explain me why it does works like this (I guess it's normal) ? How I'm supposed to solve this when creating programs (Should I detect the executable path in my C++ code or should I organize the resources files another way than on windows ?)

  • How do I use a relative path in XDocument.Load?

    - by PaulC
    I have an XML file named PageData.xml in my App_Data folder. I want to populate an XDocument with this file using XDocument.Load. If I supply the full physical path it works, i.e.: XDocument vXDoc = XDocument.Load("/Work/Project/Web/100413 Dev/App_Data/PageData.xml"); ...where "Work" is a folder on my C: drive. If I try a relative path like this, though, I get a DirectoryNotFoundException: XDocument vXDoc = XDocument.Load("AppData/PageData.xml"); "Could not find a part of the path 'C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\AppData\PageData.xml'." This is obviously wrong, but there must be an easy way to set the correct relative path? What am I overlooking? Your help is appreciated.

  • Convert RGB value to HSV

    - by marionmaiden
    I've found a method on the Internet to convert RGB values to HSV values. Unfortunately, when the values are R=G=B, I'm getting a NaN, because of the 0/0 operation. Do you know if there is an implemented method for this conversion in Java, or what do I have to do when I get the 0/0 division to get the right value of the HSV? Here comes my method, adapted from some code on the Internet: public static double[] RGBtoHSV(double r, double g, double b){ double h, s, v; double min, max, delta; min = Math.min(Math.min(r, g), b); max = Math.max(Math.max(r, g), b); // V v = max; delta = max - min; // S if( max != 0 ) s = delta / max; else { s = 0; h = -1; return new double[]{h,s,v}; } // H if( r == max ) h = ( g - b ) / delta; // between yellow & magenta else if( g == max ) h = 2 + ( b - r ) / delta; // between cyan & yellow else h = 4 + ( r - g ) / delta; // between magenta & cyan h *= 60; // degrees if( h < 0 ) h += 360; return new double[]{h,s,v}; }

  • How do you work out the IIS Virtual Path for an application?

    - by joshcomley
    When I try to change the ASP.NET version to v4 on IIS 6, I receive the following warning: Changing the Framework version requires a restart of the W3SVC service. Alternatively, you can change the Framework version without restarting the W3SVC service by running: aspnet_regiis.exe -norestart -s IIS-Viirtual-Path Do you want to continue (this will change the Framework version and restart the W3SVC service)? How do I work out IIS-Virtual-Path? I have tried the obvious paths i.e.: aspnet_regiis.exe -norestart -s "/WebSites/Extranet/AppName" Where WebSites is the name of the folder in IIS, Extranet the name of the root app and AppName the name of the Virtual Directory application I am trying to change. Thanks! Edit: How do I work out the virtual path for the Auth virtual directory in following IIS6 setup: I have tried: aspnet_regiis.exe -norestart -s "/Web Sites/Extranet/Auth" aspnet_regiis.exe -norestart -s "Auth" I get: Installation stopped because the specified path (WhateverIPutIn) is invalid.

  • Group multiple media queries formed as output of LESS css

    - by Goje87
    I was planning to use LESS css in my project (PHP). I am planning to use its nested @media query feature. I find that it fails to group the multiple media queries in the output css it generates. For example: // LESS .header { @media all and (min-width: 240px) and (max-width: 319px) { font-size: 12px; } @media all and (min-width: 320px) and (max-width: 479px) { font-size: 16px; font-weight: bold; } } .body { @media all and (min-width: 240px) and (max-width: 319px) { font-size: 10px; } @media all and (min-width: 320px) and (max-width: 479px) { font-size: 12px; } } // output CSS @media all and (min-width: 240px) and (max-width: 319px) { .header { font-size: 12px; } } @media all and (min-width: 320px) and (max-width: 479px) { .header { font-size: 16px; font-weight: bold; } } @media all and (min-width: 240px) and (max-width: 319px) { .body { font-size: 10px; } } @media all and (min-width: 320px) and (max-width: 479px) { .body { font-size: 12px; } } My expected output is (@media queries grouped) @media all and (min-width: 240px) and (max-width: 319px) { .header { font-size: 12px; } .body { font-size: 10px; } } @media all and (min-width: 320px) and (max-width: 479px) { .header { font-size: 16px; font-weight: bold; } .body { font-size: 12px; } } I would like to know if it can be done in LESS it self or is there any simple CSS parser I can use to manipulate the output CSS to group the @media queries.

  • How can I "best fit" an arbitrary cairo (pycairo) path?

    - by Daniel Straight
    It seems like given the information in stroke_extents() and the translate(x, y) and scale(x, y) functions, I should be able to take any arbitrary cairo (I'm using pycairo) path and "best fit" it. In other words, center it and expand it to fill the available space. Before drawing the path, I have scaled the canvas such that the origin is the lower left corner, up is y+, right is x+, and the height and width are both 1. Given these conditions, this code seems to correctly scale the path: # cr is the canvas extents = cr.stroke_extents() x_size = abs(extents[0]) + abs(extents[2]) y_size = abs(extents[1]) + abs(extents[3]) cr.scale(1.0 / x_size, 1.0 / y_size) I cannot for the life of me figure out the translating though. Is there a simpler approach? How can I "best fit" a cairo path on its canvas? Please ask for clarification if anything is unclear in this question.

  • What is the most efficiant way to get the highest and the lowest value in a Array

    - by meo
    is there something like PHP: max() in javascript? lets say i have an array like this: [2, 3, 23, 2, 2345, 4, 86, 8, 231, 75] and i want to return the highest and the lowest value in this array. What is the fastest way to do that? i have tried: function madmax (arr) { var max = arr[0], min = arr[1] if (min > max) { max = arr[1] min = arr[0] } for (i=1;i<=arr.length;i++){ if( arr[i] > max ) { max = arr[i] }else if( arr[i] < min ) { min = arr[i] } } return max, min } madmax([123, 2, 345, 153, 5, 98, 456, 4323456, 1, 234, 19874, 238, 4]) Is there a simpler way retrieve the max and min value of a array?

  • How can I determine a file extension given a file path in LaTeX?

    - by Frank
    I am attempting to write a LaTeX package which leverages the minted package's \inputminted command. My \mycommand command takes two parameters, the first being a path to a file, and I want to pass the file's extension to the \inputminted command: \newcommand\mycommand[2]{ \inputminted{#1}{...} } Note that the above won't work since the full path is passed to \inputminted. Example: \mycommand{/path/to/Test.java}{blah} should invoke \inputminted{java}{...}

  • WPF Binding with RelativeSource of Window Requires "DataContext" in Path?

    - by Phil Sandler
    The following code works, but I'm curious as to why I need the Path to be prefixed with "DataContext"? In most other cases, the path used is relative to DataContext. Is it because I am using a RelativeSource? Because the source is at the root level (Window)? <Style TargetType="TextBox"> <Setter Property="IsReadOnly" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.IsReadOnly}"/> </Style>

  • C#: How do I get the path of the assembly the code is in?

    - by George Mauer
    Is there a way to get the path for the assembly in which the current code resides? I do not want the path of the calling assembly, just the one containing the code. Basically my unit test needs to read some xml test files which are located relative to the dll. I want the path to always resolve correctly regardless of whether the testing dll is run from TestDriven.NET, the MbUnit GUI or something else. Edit: People seem to be misunderstanding what I'm asking. My test library is located in say c:\projects\myapplication\daotests\bin\Debug\daotests.dll and I would like to get the "*c:\projects\myapplication\daotests\bin\Debug*" path. The three suggestions so far fail me when I run from the MbUnit Gui: Console.Out.Write(Environment.CurrentDirectory) gives c:\Program Files\MbUnit Console.Out.Write(System.Reflection.Assembly.GetAssembly(typeof(DaoTests)).Location) gives C:\Documents and Settings\george\Local Settings\Temp\ ....\DaoTests.dll Console.Out.Write(System.Reflection.Assembly.GetExecutingAssembly().Location) gives the same as the previous

  • How to store a file on a server(web container) through a Java EE web application?

    - by Yatendra Goel
    I have developed a Java EE web application. This application allows a user to upload a file with the help of a browser. Once the user has uploaded his file, this application first stores the uploaded file on the server (on which it is running) and then processes it. At present, I am storing the file on the server as follows: try { FormFile formFile = programForm.getTheFile(); // formFile represents the uploaded file String path = getServlet().getServletContext().getRealPath("") + "/" + formFile.getFileName(); System.out.println(path); file = new File(path); outputStream = new FileOutputStream(file); outputStream.write(formFile.getFileData()); } where, the formFile represents the uploaded file. Now, the problem is that it is running fine on some servers but on some servers the getServlet().getServletContext().getRealPath("") is returning null so the final path that I am getting is null/filename and the file doesn't store on the server. When I checked the API for ServletContext.getRealPath() method, I found the following: public java.lang.String getRealPath(java.lang.String path) Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is the context path of this ServletContext. The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive). So, Is there any other way by which I can store files on those servers also which is returning null for getServlet().getServletContext().getRealPath("")

  • How is this algorithm, for finding maximum path on a Directed Acyclical Graph, called?

    - by Martín Fixman
    Since some time, I'm using an algorithm that runs in complexity O(V + E) for finding maximum path on a Directed Acyclical Graph from point A to point B, that consists on doing a flood fill to find what nodes are accessible from note A, and how many "parents" (edges that come from other nodes) each node has. Then, I do a BFS but only "activating" a node when I already had used all its "parents". queue <int> a int paths[] ; //Number of paths that go to note i int edge[][] ; //Edges of a int mpath[] ; //max path from 0 to i (without counting the weight of i) int weight[] ; //weight of each node mpath[0] = 0 a.push(0) while not empty(a) for i in edge[a] paths[i] += 1 a.push(i) while not empty(a) for i in children[a] mpath[i] = max(mpath[i], mpath[a] + weight[a]) ; paths[i] -= 1 ; if path[i] = 0 a.push(i) ; Is there any special name for this algorithm? I told it to an Informatics professor, he just called it "Maximum Path on a DAG", but it doesn't sound good when you say "I solved the first problem with a Fenwick Tree, the second with Dijkstra, and the third with Maximum Path".
