  • Unix - "xargs" - output "in the middle" (not at the end!)

    - by Petike
    Hello, example use of "xargs" application in Unix can be something like this: ls | xargs echo which is the same as (let's say I have "someFile" and "someDir/" in the working dir): echo someFile someDir so "xargs" take its "input" and place it "at the end" of the next command (here at the end of echo). But sometimes I want xargs to place its input somewhere "in the middle" of next command. For example: find . -type f -name "*.cpp" -print | xargs g++ -o outputFile so if I had in the current directory files "a.cpp" "b.cpp" "c.cpp" the output would be the same as with the command: g++ -o outputFile a.cpp b.cpp c.cpp but I want to have something like this: g++ a.cpp b.cpp c.cpp -o outputFile Is there a way to do it? P.S.: I need it in some cases, because e.g.: i586-mingw32msvc-g++ -o outputFile `pkg-config --cflags --libs gtkmm-2.4` a.cpp b.cpp c.cpp doesn't work but this one works fine: i586-mingw32msvc-g++ a.cpp b.cpp c.cpp -o outputFile `pkg-config --cflags --libs gtkmm-2.4` Thanks.

  • Creating a function that will handle objects with common properties

    - by geocine
    Take this as an example I have trimmed this example for readability and you may not find the use of this concept here. class Teacher() { public Name {get; set;} public Salt {get; set;} public Department{get; set;} } class Student() { public Name {get; set;} public Salt {get; set;} public Section{get; set;} } public string GetEncryptedName(object Person) { //return encrypted name based on Name and Salt property return encrypt(object.Salt,object.Name) } callig the function GetEncryptedName(Teacher) GetEncryptedName(Student) How do you implement this kind of stuff?

  • Converting a stopwatch time to milliseconds (regex)

    - by Nick
    I'm trying to figure out the best way to convert a string containing a time to an integer number of milliseconds. I'm using a suboptimal way using a bunch of preg_match()'s and some array handling, but I was wondering if there was an elegant way. Here are some example stopwatch times (some wouldn't actually be seen on a stopwatch but need to be converted anyway): 3:34:05.81 34:05 5 (just 5 seconds) 89 (89 seconds) 76:05 (76 minutes, 5 seconds) Millseconds will not extend past 2 decimal places. You can give me an example using either PHP or Javascript regex functions. Thanks!

  • How do I determine if a property was overriden?

    - by Benjamin
    Hello I am doing a project that where I need to register all the properties, because of the system being so huge it would require a lot of work to register all the properties that i want to be dependent for the purpose of Xaml. The goal is to find all properties that are on the top of the tree. so basically public class A{ public int Property1 { get; set; } } public class B : A{ public int Property2 { get; set; } public virtual int Property3 { get; set; } } public class C : B{ public override int Property3 { get; set; } public int Property4 { get; set; } public int Property5 { get; set; } } The end result would be something like this A.Prorperty1 B.Property2 B.Property3 C.Property4 C.Property5 If you notice I don't want to accept overridden properties because of the way I search for the properties if I do something like this C.Property3 for example and it cannot find it it will check C's basetype and there it will find it. This is what I have so far. public static void RegisterType( Type type ) { PropertyInfo[] properties = type.GetProperties( BindingFlags.Public | BindingFlags.Instance | BindingFlags.DeclaredOnly | BindingFlags.GetProperty | BindingFlags.SetProperty ); if ( properties != null && properties.Length > 0 ) { foreach ( PropertyInfo property in properties ) { // if the property is an indexers then we ignore them if ( property.Name == "Item" && property.GetIndexParameters().Length > 0 ) continue; // We don't want Arrays or Generic Property Types if ( (property.PropertyType.IsArray || property.PropertyType.IsGenericType) ) continue; // Register Property } } } What I want are the following: Public properties, that are not overridden, not static, not private Either get and set properties are allowed They are not an array or a generic type They are the top of the tree ie C class in the example is the highest (The property list example is exactly what I am looking for) They are not an indexer property ( this[index] ) Any help will be much appreciated =).

  • How do I change the list using mutable lists in Racket or Scheme?

    - by exOne
    I need your help Can anyone help me? first question This procedure should modify each element which’s index in the list is even. The value of the element should be equal to the new-element. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-indices number-list 10) The new list: 1 10 8 10 43 10 78 second question This problem is the extended version of Question 1. (modify-even-odd-indices my-list new-element modification-type) This procedure should modify each element according to the modification-type. The modification-type can be even or odd. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-odd-indices number-list 10 ‘even’) The new list: 1 10 8 10 43 10 78 (modify-even-odd-indices number-list 10 ‘odd’) The new list: 10 56 10 1 10 9 10

  • Find files in a folder using Java

    - by Sii
    Hello, I'm new here so be kind to my stupidity :) What I need to do if Search a folder say C:\example I then need to go through each file and check to see if it matches a few start characters so if files start temp****.txt tempONE.txt tempTWO.txt So if the file starts with temp and has an extension .txt I would like to then put that file name into a File file = new File("C:/example/temp***.txt); so I can then read in the file, the loop then needs to move onto the next file to check to see if it meets as above. I hope this makes sense, thanks for taking the time to view this I do apperciate it :)

  • Uploading a file to AppEngine using GWT: How to provide feedback to the user?

    - by jcdmb
    Hello everyone, I have a GWT-FormPanel on my website, where people can upload pictures and answer some questions. It's working very well. The only problem is: I would like to provide a feedback to the user (for example: 0% to 100%) during the actual file process. But I have no idea how I can do that. I think that's a very common issue, that's why I would like to ask you guys if you know any tutorial or example that could help me to solve this problem. I've already tried GWT-Upload, but it does not do what I want: I have a submit button at the end of the FormPanel and the GWTUpload has it's own "SEND" button, which I don't want to have. Thanks in advance for helping and merry Christmas!

  • Autocomplete for generic types in Eclipse

    - by AvrDragon
    "Refer to objects by their interfaces" is a good practise, as mentioned in Effective Java. So for example i prefer List<String> al = new ArrayList<String>(); over ArrayList<String> al = new ArrayList<String>(); in my code. One annoying thing is that if i type ArrayList<String> al = new and then hit Ctrl+Space in Eclipse i get ArrayList<String>() as propostal. But if i type List al = new and then hit Ctrl+Space i will get only propostal to define anonymous inner class, but not propostals such as new ArrayList<String>(), what is 99% the case, or for example new Vector<String>(). Is there any way to get the subclasses as propostals for generic types?

  • Java Enum Newbie Question

    - by ikurtz
    i have a situation where i need the Checker enum below used in multiple classes: package Sartre.Connect4; public enum Checker { EMPTY, RED, YELLOW } so i put the Checker in a Checker.java file and then from the classes that need it i simply do the following: example: public Cell(){ currentCell = Checker.EMPTY; } example: public Cell(Checker checker){ currentCell = checker; } and the code compiles fine and runs fine also. so what is my question? well being new to Java i am just wondering if the way i use Checker without encapsulating it in a class is a sound implementation? it may be because of The enum declaration defines a class (called an enum type). as noted in Java docs enum tutorial page. thank you for your insight into this matter.

  • Get a single element with PHP and XPath

    - by daliz
    Lots of tutorials around the net but none of them can explain me this: How do I select a single element (in a table, for example), having its absolute XPath? Example: I have this: /html/body/table/tbody/tr[2]/td[2]/table/tbody/tr/td/table[3]/tbody/tr/td/table/tbody/tr[3]/td/table/tbody/tr[4]/td[5]/span What's that PHP function to get the text of that element?! Really I could not find an answer. Found lots of guides and hints to get all the elements of the table, all the buttons of a form, etc, but not what I need. Thank you.

  • How to save an image in it's original format?

    - by Patrick Klug
    I am trying to figure out how I can get the original format of an image so that I can store it with the same encoding. It seems that the only way to save an Image is by using a BitmapEncoder but I don't know how I can get the correct format from the image. Example: Clipboard.GetImage() returns a InteropBitmap which doesn't seem to contain any information about the original format. I also tried using an Extension method: public static void Save(this BitmapImage image, System.IO.Stream stream) { var decoder = BitmapDecoder.Create(image.StreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default); var encoder = BitmapEncoder.Create(decoder.CodecInfo.ContainerFormat); foreach (var frame in decoder.Frames) { encoder.Frames.Add(BitmapFrame.Create(decoder.Frames[0])); } encoder.Save(stream); } but the problem is that a) the ImageSource is not always a BitmapImage (Clipboard.GetImage()) for example and b) the image.StreamSource can be null in some cases (seems to be when the image is loaded via a relative Uri)

  • OpenGL and layouts

    - by Hnefi
    I'm using OpenGL to render a game view in my android application. The game is turn based and I wish to add some buttons to the interface. I'd prefer to use standard Android widgets, structured in an XML-generated layout (or, if I have to, a hardcoded layout) and put the OpenGL view in its own window as part of that layout. So in regards to this, I have 3 questions: 1: Is such a thing possible? I've done a few half-hearted tries, but have had no luck so far. 2: Is such a thing advisable? Does it carry a significant performance penalty, for example, over using OpenGL-based homebrew widgetry? 3: Is it possible to pass particular arguments to instances created in XML layouts? For example, my current OpenGL view has three arguments in its constructor; is it somehow possible for me to invoke that particular constructor with particular parameters when it's part of a layout?

  • speed up calling lot of entities, and getting unique values, google app engine python

    - by user291071
    OK this is a 2 part question, I've seen and searched for several methods to get a list of unique values for a class and haven't been practically happy with any method so far. So anyone have a simple example code of getting unique values for instance for this code. Here is my super slow example. class LinkRating2(db.Model): user = db.StringProperty() link = db.StringProperty() rating2 = db.FloatProperty() def uniqueLinkGet(tabl): start = time.time() dic = {} query = tabl.all() for obj in query: dic[obj.link]=1 end = time.time() print end-start return dic My second question is calling for instance an iterator instead of fetch slower? Is there a faster method to do this code below? Especially if the number of elements called be larger than 1000? query = LinkRating2.all() link1 = 'some random string' a = query.filter('link = ', link1) adic ={} for itema in a: adic[itema.user]=itema.rating2

  • Maven archetype from project - how to preserve package names ?

    - by lisak
    Hey, I'm trying to grab my project and generate an Archetype from it via : archetype:create-from-project The thing is, that my project has src/main/java package structure com.sample.app, but the archetype must have it as I want (org.example.game) ... Ideally as user want when generating the project from archetype, but that is impossible I suppose. It would have to grab groupId and artifactId and generate archetype-resources/src/main/java based on this input. Anyway, that's why there is this argument I suppose : packageName mvn archetype:create-from-project -DpackageName=org.example.game But it doesn't work and there is still archetype-resources/src/main/java/org/sample/game ..

  • How to deal with name/value pairs of function arguments in MATLAB

    - by Richie Cotton
    I have a function that takes optional arguments as name/value pairs. function example(varargin) % Lots of set up stuff vargs = varargin; nargs = length(vargs); names = vargs(1:2:nargs); values = vargs(2:2:nargs); validnames = {'foo', 'bar', 'baz'}; for name = names validatestring(name{:}, validnames); end % Do something ... foo = strmatch('foo', names); disp(values(foo)) end example('foo', 1:10, 'bar', 'qwerty') It seems that there is a lot of effort involved in extracting the appropriate values (and it still isn't particularly robust again badly specified inputs). Is there a better way of handling these name/value pairs? Are there any helper functions that come with MATLAB to assist?

  • How do I load the background image from another page?

    - by bbeckford
    Hi all, I'm creating a page that loads content from other pages using jQuery like this: $('#newPage').load('example.html' + ' #pageContent', function() { loadComplete(); }); That all works fine. Now what I want to do is change the background image of the current page to the background image of the page I'm loading from. This is what I'm doing now but I can't for the life of me get it to work: $.get('example.html', function(data) { var pageHTML = $(data); var pageBody = pageHTML.$('body'); alert(pageBody.attr("background")); }); What am I doing wrong?? Thanks, -Ben

  • Click to make body text larger | JavaScript

    - by Wayne
    Please note this is just an example: <img src="img/normal-font.png" onclick="javascript:document.body.style.fontSize = '13px';" /> &nbsp; <img src="img/medium-font.png" onclick="javascript:document.body.style.fontSize = '14px';" /> &nbsp; <img src="img/large-font.png"onclick="javascript:document.body.style.fontSize = '15px';" /> The body text does indeed enlarge if I choose one of them, but what I like to include is remembering what option you've chosen by reading cookies. In fact, I have no experience in creating cookies in JS, only in PHP. Could someone come up with an example of how to make cookies the simpliest way remembering my option, but whenever someone clicks another one, it should get rid of the cookie that was last set, e.g. Cookie value has 15px, then should update it or remove it with a new cookie with a new value of 13px and so on. Thanks :)

  • Using Linq on a Dataset

    - by JasonMHirst
    Can someone enlighthen me with regards to Linq please? I have a dataset that is populated via a SQL Stored Procedure, the format of which is below: Country | Brand | Variant | 2004 | 2005 | 2006 | 2007 | 2008 The number of rows varies between 50 and several thousand. What I'm trying to do is use Linq to interrogate the dataset (there will be several Linq queries based on user options), but a simple example would be to SUM the year columns based on Brand. I have the following that I believe creates a template for me to work with: But from here on I'm absolutely stuck! sqlDA.Fill(ds, "Profiler") Dim brandsQuery = From cust In ds.Tables(0).AsEnumerable() Select _BrandName = cust.Item("BrandName"), _y0 = cust.Item("1999"), _y1 = cust.Item("2004"), _y2 = cust.Item("2005"), _y3 = cust.Item("2006"), _y4 = cust.Item("2007"), _y5 = cust.Item("2008") I'm tried to look at examples, but can't see any that are VB.Net based and/or show me how to Sum/Group. Can someone please provide an example so I can perhaps learn from it. Thanks.

  • A btter way to represent Same value given multiple values(C#3.0)

    - by Newbie
    I have a situation for which I am looking for a more elegant solution. Consider the below cases "BKP","bkp","book-to-price" (will represent) BOOK-TO-PRICE "aop","aspect oriented program" (will represent) ASPECT-ORIENTED-PROGRAM i.e. if the user enter BKP or bkp or book-to-price , the program should treat that as BOOK-TO-PRICE. The same holds good for the second example(ASPECT-ORIENTED-PROGRAM). I have the below solution: Solution: if (str == "BKP" || str == "bkp" || str == "book-to-price" ) return "BOOK-TO-PRICE". But I think that there can be many other better solutions . Could you people please give some suggestion.(with an example will be better) I am using C#3.0 and dotnet framework 3.5

  • Encrypting password in compiled C or C++ code

    - by Daniel
    Hello!, I know how to compile C and C++ Source files using GCC and CC in the terminal, however i would like to know if its safe to include passwords in these files, once compiled. For example.. i check user input for a certain password e.g 123, but it appears compiled C/C++ programs is possible to be decompiled. Is there anyway to compile a C/C++ source file, while keeping the source completely hidden.. If not, could anyone provide a small example of encrypting the input, then checking against the password e.g: (SHA1, MD5)
