• NAS backup - multiple machines

  - by Adam

  HI We are looking to backup between 50-100 servers to a NAS box each night (Contains of each server ie files and folders). We need the backup application to backup to a NAS and perform incremental backups following the full backup. We also need to be able to store versions of each file. The full backup will probably be about 5TB. Does anyone know a a cheap or free application which will do this? Thanks

• .NET ClickOnce not installing prerequisite files?

  - by proudgeekdad

  I have a .NET project that uses Crystal Reports. The application is distributed using ClickOnce. Things work great if the user has Crystal installed on their computer. However, not all of the end users have Crystal Reports installed on their computers. These users are receiving the following error... "Unable to install or run the application. The application requires that assembly CrystalDecisions.ReportAppServer.XmlSerialize Version 10.5.3700.0 be installed in the Global Assembly Cache (GAC) first." Is there a way to force ClickOnce installs to ensure that a prerequisite is installed?

• FOR loop performance in Javascript

  - by AndrewMcLagan

  As my research leads me to believe that for loops are the fastest iteration construct in javascript language. I was thinking that also declaring a conditional length value for the for loop would be faster... to make it clearer, which of the following do you think would be faster? Example ONE for(var i = 0; i < myLargeArray.length; i++ ) { console.log(myLargeArray[i]); } Example TWO var count = myLargeArray.length; for(var i = 0; i < count; i++ ) { console.log(myLargeArray[i]); } my logic follows that on each iteration in example one accessing the length of myLargeArray on each iteration is more computationally expensive then accessing a simple integer value as in example two?

• Error Instantiating an Inner Class in Parent's Constructor...

  - by stormin986

  In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class. public class MainApplication extends Application { public class Data { public String x; public String y; public String z; } private Data data; MainApplication() { data = new Data() data.x = "String"; } } After I instantiate the object in the constructor, I get a runtime error when I try to assign any of the inner class object's variables. Any idea what's up here??

• Can silverlight detect or communicate across browser instances?

  - by isolatedIterator

  User starts up a silverlight application in their browser by navigating to a given URL. User then opens another browser and starts up the same silverlight application by navigating to the same URL. Can the second instance of the application detect that there is already an instance running on the same computer? Can it detect itself if both applications are running within the same browser instance? I would expect the answer to be 'no' but thought that i would ask it anyway. Otherwise i believe that i will have to setup a webservice and have each instance register itself and send requests to other instances from the same IP. does that sound reasonable?

• How can I load scripts, styles and images from a non-URL source?

  - by Jen

  I am integrating WebKit (via Qt) into an application. Instead of having WebKit retrieve scripts, CSS files and images via URLs, I want my application to provide them (e.g. retrieved from a database). For example, a "regular" web page may contain this tag: <IMG src="photos/album1/123456.jpg"> Instead of WebKit fetching this image from a server or the file system, I would prefer some kind of callback that allows my application to provide this image. How can I accomplish this?

• Backbone collection's URL depends on initialize function

  - by egidra

  I have a Backbone collection whose URL depends on the initialize function. When I create an instance of this Backbone collection, I pass in an ID to filter which instances of the model appear. Here is what the collection's code looks like: var GoalUpdateList = Backbone.Collection.extend({ // Reference the Goal Update model model: GoalUpdate, // Do HTTP requests on this endpoint url: "http://localhost:8000/api/v1/goal_update/?goal__id=" + this.goal_id + "&format=json", // Set the goal ID that the goal update list corresponds to initialize: function(goal_id) { this.goal_id = goal_id; console.log(this.goal_id); console.log(this.url); }, }); Of course, this doesn't work. this.goal_id is seen as being undefined. I guess because the URL is set before the initialization function is run.

• c++ networking issue- retrnsmittion without ccongestion

  - by gln

  I wrote an application in c++ which send data over tcp connection to several machines.as part of the protocol I use in my application, the other side sends hearbeat messages from time to time, then I know that the connection is still alive. now, I want this application to work on 100 machines or more at the same time. but, I see that sometimes I don't get these heartbeat messages although they sent: I see in wireshark that the packet arrived, then my OS doesn't ack on this message, so there are some retransmit without any ack from my OS. if I look in the window size property - I saw that there is no issue in this part. what can be the root cause for this behavior? it is something in my code that I should change? this is my select code: int res = select(fdCount, &readFds, NULL, NULL, NULL ); I'm using server 2008 r2. Please help me! thanks

• Move Global.asax to iHttpModule when using ASP.NET MVC

  - by rockinthesixstring

  I have successfully created an iHttpModule to replace my Global.asax file in many Web Forms applications. But in looking at the Global.asax file in my MVC application, the methods are totally different. I'm wondering if it is still possible to create this same thing in an MVC app. I know it's not necessary and the Global.asax works just fine. I suppose I just want to have nothing but the web.config in the root directory of my application. Also, I am putting all of my classes in a separate class library project instead of a folder in my MVC application. Not sure if this makes a difference or not.

• openmp vs opencl for computer vision

  - by user1235711

  I am creating a computer vision application that detect objects via a web camera. I am currently focusing on the performance of the application My problem is in a part of the application that generates the XML cascade file using Haartraining file. This is very slow and takes about 6days . To get around this problem I decided to use multiprocessing, to minimize the total time to generate Haartraining XML file. I found two solutions: opencl and (openMp and openMPI ) . Now I'm confused about which one to use. I read that opencl is to use multiple cpu and GPU but on the same machine. Is that so? On the other hand OpenMP is for multi-processing and using openmpi we can use multiple CPUs over the network. But OpenMP has no GPU support. Can you please suggest the pros and cons of using either of the libraries.

• "iTunes.app" to accept incoming network connections?

  - by cust0s

  Every time I open iTunes I get the the following warning: Do you want the application "iTunes.app" to accept incoming network connections? Clicking Deny may limit the application's behavior. This setting can be changed in the Firewall pane of Security preferences. I always click "Allow" but it still pops up. I set the OS X firewall to allow incoming connections for iTunes. Any suggestions on how to fix this?

• Emacs / Wanderlust / OSX -- Any ideas what could cause Emacs to acquire focus when using Wanderlust?

  - by lawlist

  I'm using Wanderlust with Emacs on OSX 10.6.8 (Snow Leopard) and frequently switch to a different application while Wanderlust is prefetching e-mails and organizing the summary buffers. At several stages during this process, Emacs acquires focus and steels me away from whatever I was doing in another application. I don't think Wanderlust has any built-in applescripts and I haven't added any, so I have no idea what could be causing Emacs to demand focus. Any ideas how to leave Emacs in the background while updating Wanderlust?

• Problem with Juggernaut and transparent wmode in Adobe AIR

  - by vortexmk

  Hi, I am trying to use juggernaut in Adobe AIR application, however the big issue with this is that the juggernaut flash file should have wmode parameter set to 'transparent'. This is a bit of a problem for juggernaut because it seems that it doesn't work with that parameter included. The interesting part is that it is working under Linux on all browsers and in air application, but on Windows it's working only with Safari all other browsers including the AIR application are not even connecting to the juggernaut server. So the question is, what is the cause of this and if anyone had similar problem I would be interested to hear about solutions or workarounds. Thanks, Peco

• Running Java plugin 1.5 on Firefox + Snow Leopard

  - by Sam

  I have a Java applet that needs to be able to run on Java 1.5. I have successfully installed Java 1.5 on Snow Leopard and I am able to use it to run applets in Safari by changing the order of the versions in Java Preferences. However, Firefox (3.5.9) doesn't seem to be able to pick up the changes and keeps reverting to using the Java 1.6 plugin. How do I force Firefox to use the Java 1.5 plugin? I tried re-linking the /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK folder to point to my 1.5 directory, but that seems to change the system-level Java runtime, not the Firefox plugin (it opened up the console differently, but inside the console it reported Java plugin 1.6.0).

• Communication via internet in Java

  - by Stuart

  What I mean is like servers on video games. You can run an application and it will set up a server on your computer with an IP and a port. For example, how would you make an application where one host application sets up a thing where it has an IP and a port, and another computer that has access to the internet as well can type in the IP and port and it would be able to communicate with the host? I mean simple communication, like sending a boolean or String. And would there be any security problems that would be needed to fix?

• Zipping only files using powershell

  - by SteB

  I'm trying to zip all the files in a single directory to a different folder as part of a simple backup routine. The code runs ok but doesn't produce a zip file: $srcdir = "H:\Backup" $filename = "test.zip" $destpath = "K:\" $zip_file = (new-object -com shell.application).namespace($destpath + "\"+ $filename) $destination = (new-object -com shell.application).namespace($destpath) $files = Get-ChildItem -Path $srcdir foreach ($file in $files) { $file.FullName; if ($file.Attributes -cne "Directory") { $destination.CopyHere($file, 0x14); } } Any ideas where I'm going wrong?

• Permissions required to look up a domain user's group memberships

  - by adrianbanks

  I am writing some code to look up the members of particular domain groups. Does the user that this application runs as need any particular permissions on the domain to get this information? Background: I have already determined that the application needs to be run as a domain user to be able to query information from the domain. I have a list of group names and for each group, I need to look up the members of that group on the domain and get their names/usernames.

• Retrieving data from database. Retrieve only when needed or get everything?

  - by RHaguiuda

  I have a simple application to store Contacts. This application uses a simple relational database to store Contact information, like Name, Address and other data fields. While designing it, I question came to my mind: When designing programs that uses databases, should I retrieve all database records and store them in objects in my program, so I have a very fast performance or I should always gather data only when required? Of course, retrieving all data can only be done if it`s not too many, but do you use this approach when you make sure that the database will be small (< 300 records for example)? I have designed once a similar application that fetches data only when needed, but that was slow (using a Access database). Thanks for all help.

• Python in AWS Elastic Beasntalk: Private package dependencies

  - by Adam Matan

  I would like to deploy a Python Flask application on beanstalk. The application depends on external packages (e.g. geopy) and internal packages (e.g. adam_geography). The manual Create a requirements.txt file and place it in the top-level directory of your source bundle. This would probably fetch geopy and its dependencies, but would not fetch adam_geography which is available from a custom repo inside my VPC. How do I specify/upload private, internal Python package dependencies in a Beanstalk application?
