  • Looping and pausing after loading ajax content in Javascript JQuery

    - by Tristan
    I have what I though was a simple problem to solve (never is!) I'm trying to loop through a list of URL's in a javascript array I have made, load the first one, wait X seconds, then load the second, and continue until I start again. I got the array and looping working, trouble is, however I try and implement a "wait" using setInterval or similar, I have a structural issue, as the loop continues in the background. I tried to code it like this: $(document).ready(function(){ // my array of URL's var urlArray = new Array(); urlArray[0] = "urlOne"; urlArray[1] = "urlTwo"; urlArray[2] = "urlThree"; // my looping logic that continues to execute (problem starts here) while (true) { for (var i = 0; i < urlArray.length; i++) { $('#load').load(urlArray[i], function(){ // now ideally I want it to wait here for X seconds after loading that URL and then start the loop again, but javascript doesn't seem to work this way, and I'm not sure how to structure it to get the same effect }); } } });

  • What's the best way of accessing a DRb object (e.g. Ruby Queue) from Scala (and Java)?

    - by Tom Morris
    I have built a variety of little scripts using Ruby's very simple Queue class, and share the Queue between Ruby and JRuby processes using DRb. It would be nice to be able to access these from Scala (and maybe Java) using JRuby. I've put together something Scala and the JSR-223 interface to access jruby-complete.jar. import javax.script._ class DRbQueue(host: String, port: Int) { private var engine = DRbQueue.factory.getEngineByName("jruby") private var invoker = engine.asInstanceOf[Invocable] engine.eval("require \"drb\" ") private var queue = engine.eval("DRbObject.new(nil, \"druby://" + host + ":" + port.toString + "\")") def isEmpty(): Boolean = invoker.invokeMethod(this.queue, "empty?").asInstanceOf[Boolean] def size(): Long = invoker.invokeMethod(this.queue, "length").asInstanceOf[Long] def threadsWaiting: Long = invoker.invokeMethod(this.queue, "num_waiting").asInstanceOf[Long] def offer(obj: Any) = invoker.invokeMethod(this.queue, "push", obj.asInstanceOf[java.lang.Object]) def poll(): Any = invoker.invokeMethod(this.queue, "pop") def clear(): Unit = { invoker.invokeMethod(this.queue, "clear") } } object DRbQueue { var factory = new ScriptEngineManager() } (It conforms roughly to java.util.Queue interface, but I haven't declared the interface because it doesn't implement the element and peek methods because the Ruby class doesn't offer them.) The problem with this is the type conversion. JRuby is fine with Scala's Strings - because they are Java strings. But if I give it a Scala Int or Long, or one of the other Scala types (List, Set, RichString, Array, Symbol) or some other custom type. This seems unnecessarily hacky: surely there has got to be a better way of doing RMI/DRb interop without having to use JSR-223 API. I could either make it so that the offer method serializes the object to, say, a JSON string and takes a structural type of only objects that have a toJson method. I could then write a Ruby wrapper class (or just monkeypatch Queue) to would parse the JSON. Is there any point in carrying on with trying to access DRb from Java/Scala? Might it just be easier to install a real message queue? (If so, any suggestions for a lightweight JVM-based MQ?)

  • Avoiding mass propagation of properties and events for exposure to ViewModels.

    - by firoso
    I have an MVVM application I am developing that is to the point where I'm ready to start putting together a user interface (my client code is largely functional) I'm now running into the issue that I'm trying to get my application data to where I need it so that it can be consumed by the view model and then bound to the view. Unfortunately, it seems that I've either got a few structural oversights, or I'm just going to have to face the reality that I need to be propogating events and raising excessive amounts of errors to notify view models that thier properties have changed. Let me go into some examples of my issue: I have a class "Unit" contained in a class "Test", contained in a class "Session" contained in a class "TestManager" which is contained in "TestDataModel" which is utilized by "TestViewModel" which is databound to by my "TestView" .... WHOA. Now, consider that Unit (the bottom of the heiarchy) has a property called "Results" that is updated periodically, I want to expose that to my viewmodel and then databind it to my view, trouble is, the only way I can really think to do this is to perpetuate events WAY up a chain that say "I've been updated!" and then request the new value... This seems like an aweful way to do this. Alternatively, I could register a static event and raise it, and have the appropriate "Unit view model" grab the event and request the update. This SEEMS better... but... static events? Is that a taboo idea? Also, having an expression like: TestDataModel.TestManager.Session.Test.Unit.Results[i] Seems REALLY gross to have on a View Model. I know this all reeks of a bad design issue, but I can't figure out what I did wrong? Should I be using more singleton/container controlled lifetimes type objects? Register object instances with static helper containers? Obviously these are hard questions to answer without being intimate with the existing structure, but if you've run into situations like this, what did you do to refactor? Should I just live with this, add mass events, and propogate them?

  • How to find all initializations of instance variables in a Java package?

    - by Hank Gay
    I'm in the midst of converting a legacy app to Spring. As part of the transition, we're converting our service classes from an "instantiate new ones whenever you need one" style to a Springleton style, so I need a way to make sure they don't have any state. I'm comfortable on the *nix command-line, and I have access to IntelliJ (this strikes me as a good fit for Structural Search and Replace, if I could figure out how to use it), and I could track down an Eclipse install, if that would help. I just want to make absolutely sure I've found all the possible problems. UPDATE: Sorry for the confusion. I don't have a problem finding places where the old constructor was being called. What I'm looking for is a "bullet-proof" why to search all 100+ service classes for any sort of internal state. The most obvious one I could think of (and the only one I've really found so far) is cases where we use memoization in the classes, so they have instance variables that get initialized internally instead of via Spring. This means that when the same Springleton gets used for different requests, data can leak between them. Thanks.

  • Intelligent search and generation of Java code, preferrably using Python?

    - by Ipsquiggle
    Basically, I do lots of one-off code generation, large-scale refactorings, etc. etc. in Java. My tool language of choice is Python, but I'll take whatever solutions you can offer. Here is a simplified illustration of what I would like, in a pseudocode Generating an implementation for an interface search within my project: for each Interface as iName: write class(name=iName+"Impl", implements=iName) search within the body of iName: for each Method as mName: write method(name=mName, body="// TODO implement this...") Basically, the tool I'm searching for would allow me to: parse files according to their Java structure ("search for interfaces") search for words contextualized by language elements and types ("variables of type SomeClass", "doStuff() method calls on SomeClass instances") to run searches with structural context ("within the body of the current result") easily replace or generate code (with helpers to generate, as above, or functions for replacing, "rename the interface to Foo", "insert the line Blah.Blah()", etc.) The point is, I don't want to spend a lot of time writing these things, as they are usually throwaway. But sometimes I need something just a little smarter than what grep offers. It wouldn't be too hard to write up a simplistic version of this, but if I'm going to use something like this at all, I'd expect it to be robust. Any suggestions of a tool/library that will help me accomplish this?

  • Office 2013 OCT unhandled exception when saving .RSP

    - by user52874
    I'm trying to prepare a deployment of office 2013 pro plus. If I deploy an existing .rsp file that was left behind by the old analyst (typing from the client): PS C: \\deploybox\software\Office2013\setup.exe /adminfile \\deploybox\software\Office2013\SWKS.MSP Things seem to deploy just fine. if I make any changes to the .rsp file by doing (all from the client): PS C: \\deploybox\software\Office2013\setup.exe /admin * Open SWKS.MSP * Make changes * Save under a different name SWKS1.MSP I get the following errorbox: Unhandled Exception: MsiGetSummaryInformation call failed. And if I try to deploy the new SWKS1.MSP, PS C: \\deploybox\software\Office2013\setup.exe /adminfile \\deploybox\software\Office2013\SWKS1.MSP it fails with the message: Path or file specified with /adminfile did not contain any customization patches that apply to this product or platform. If I even open the old known good .rsp file SWKS.MSP, and immediately save it as a new name SWKS1.MSP, making no changes, then the same thing happens. So what stupid newbie mistake am I making here? Thanks!

    - by coder247
    Hi Friends, I found strange virus like behaviour on my pc running windows 7. I'm not able to type properly with my keyboard. Some times it won't respond, and some other times it adds characters indefinitely to the typing area. When i click on desktop it creates new folders. When press ctrl+N on a browser windows it opens unlimited number of windows. I tried with Kaspersky and Eset antivirus trial versions but couldn't find any virus. I don't get this behaviour always.. but 50% of times... Thanks....

  • Shorten Emacs timeout of ~/.emacs read

    - by user35042
    My ~/.emacs start-up file is stored in my AFS home directory. Often when I login to a linux machine I will forget to renew my AFS credentials before attempting to edit a local (non-AFS) file with Emacs. When this happens Emacs will attempt to load ~./emacs but cannot because it is in AFS space where I do not have access. Eventually (after a minute or so) Emacs will give up trying to load ~./emacs and continue. But waiting for Emacs to timeout is annoying (typing Ctrl-Z does not seem to interrupt this timeout). I want to shorten the amount of time that Emacs waits before giving up. I have tried the suggestion at this site which says to put the following code in the site-start.el file: (with-timeout (4) (load remote-.emacs)) However, when I do that I get the error Error in init file: Symbol's value as variable is void: remote-\.emacs whenever starting Emacs. How can I shorten this timeout?

  • PHP IDE for Ubuntu Netbook Remix 9.10

    - by Alix Axel
    I've installed Ubuntu Netbook Remix on my netbook and I'm wondering what would be a good IDE to use for mainly PHP development. I've used Komodo Edit in past Linux distributions but it doesn't seem to play well with Ubuntu Network Remix (it doesn't shows up in the remix "desktop", and I don't feel like opening the terminal and typing komodo every time I need to code). I'm considering Eclipse with a PHP plugin, but I've two big problems with Eclipse: I don't like the way it forces me to create a new project when I just want to edit a file. I'm not sure which PHP plugin I should install: Eclipse PDT, PHP Eclipse or Aptana - I don't really understand the differences between Eclipse PDT and PHP Eclipse. Which IDE would you recommend (doesn't need to be Eclipse)? Thanks in advance!

  • How to swap the "fn" use of Function keys on al Apple Keyboard in Linux

    - by jfmessier
    I have an apple slim keyboard (USB) and if I want to use one of the Function Key as-is, I also have to press "fn " key first. Otherwise, it will try to perform the other function of the key, such as increasing or decreasing the display intensity, change the volume/mute, etc.... As well, the fn key is actually in the position of the "insert" key for regular keyboards. How can I fix all of that ? I really like this keyboard, as it make my typing much easier, and much more silent too. But some of those mappings that are different sometime bug me. Thanks :-)

  • "powershell has stopped working" on PS exit after creating IIS User

    - by Nick Jones
    On a Windows Server 2012 box, I'm using PS to create a new IIS User (for automated deployments using MSDeploy). The command itself appears to work fine -- the user is created -- but as soon as I exit my PowerShell session (typing exit or just closing the command window), a dialog is displayed stating "powershell has stopped working", with the following details: Problem signature: Problem Event Name: PowerShell NameOfExe: powershell.exe FileVersionOfSystemManagementAutomation: 6.2.9200.16628 InnermostExceptionType: Runtime.InteropServices.InvalidComObject OutermostExceptionType: Runtime.InteropServices.InvalidComObject DeepestPowerShellFrame: unknown DeepestFrame: System.StubHelpers.StubHelpers.GetCOMIPFromRCW ThreadName: unknown OS Version: 6.2.9200.2.0.0.400.8 Locale ID: 1033 The PS commands in question are: [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Management") [Microsoft.Web.Management.Server.ManagementAuthentication]::CreateUser("Foo", "Bar") Why is this happening and how can I avoid it? EDIT: I've also confirmed this be a problem with PowerShell 4.0, so I've added that tag. I've also submitted it on Connect. UPDATE: It appears that Windows Server 2012 R2 does not have this same bug.

  • Help with Ms Access 2007 Combo boxes

    - by Yaaqov
    What's the most efficient way to "chain" combo/boxes in an Access 2007 form, so that the result of the first affected the contents of the second? I already know how to associate a combo box on a form with a query. Here's a example of my scenario: cmbCarMake Behavior: User starts typing, and list shows all manufacturers in a table starting with those characters (e.g., "Ford") cmbCarModel Behavior: Once cmbCarMake has a selected a Make, this object will limit the possible models the user can search for by only displaying models from that one manufacturer. (e.g., "F-150") Thank you for any examples/links.

  • Running a reverse proxy in front of Splunk 4.x

    - by sgerrand
    So, I have previously installed Splunk 3.x behind a reverse proxy and downloaded the latest version (4.0.6 at time of typing) expecting it to be as easy to use as before. Sadly this was not the case. There appears to be some elements which are not being translated correctly through the reverse proxy, causing Splunk to fail. I have used the following configuration in Apache2 to no avail: ServerName monitoringbox.com DocumentRoot /path/to/nowhere ProxyRequests off ProxyPass /splunk http://127.0.0.1:8000/splunk ProxyPassReverse /splunk http://127.0.0.1:8000/splunk Order allow,deny Allow from all Has anyone else had more luck than me in setting up Splunk 4.x behind a reverse proxy?

  • AutoComplete not working in Outlook 2007

    When I go to create a new message in Outlook 2007, and I start typing the first few characters of a contact's name, no suggestions appear. I've just added all my contacts from a .csv file that was exported from Yahoo! Mail. If I type the name out, then click 'send', then it will ask me which of the contact's emails to send it to if the contact has multiple addresses. I've looked in the advanced options to make sure AutoComplete is on, which it its. What is going on? Thanks!

  • How to configure Linux to act as a Bluetooth RFCOMM SPP server?

    - by regulatre
    I'm writing a phone app for Android that connects to a bluetooth RFCOMM device in my car. My phone app talks AT commands with it. For development work, I often need to communicate with the device to try different commands and things. My neighbors are starting to think I'm weird because I sit in my car for hours on end with my laptop screen shining on my face, typing away like a script kiddie. I'd much rather configure one of my many Linux servers to act as a bluetooth RFCOMM device and allow me to connect to it (indoors, while I sit on my couch). I imagine I have to start with something like sdptool add SP But then what? I'm perfectly happy writing a perl app to handle the I/O, but I just don't know how to make the bluez stack accept connections and subsequently pipe that stream to a perl app.

  • Cannot change permissions in symlinked dropbox directory in Ubuntu 10.10

    Title pretty much says it all, but here's what I'm doing... ls -l produces this... drwx------ 1 brian brian 4096 2010-12-28 14:19 foldername -rw------- 1 brian brian 0 2010-12-28 15:54 index.html after typing something like chmod o=rx index.html the output of ls -l is the same. This happens whether or not I'm in the original location or the symlink location. However, as a further twist, the output of chmod -v o=rx index.html is the following: mode of `index.html' changed to 0605 (rw----r-x) The location is also being symlinked to by apache. What's going on with my permissions?

  • GDM Won't Automatically Start After Boot

    Ubuntu 10.04 Hi guys. I'm not sure why but quite recently, my ubuntu desktop started bringing up the command prompt login screen after booting. I want GDM to start up by default. I can manually bring up GDM by typing: sudo service gdm start or sudo /usr/sbin/gdm but I want something more permanent. The contents of /etc/X11/default-display-manager point to /usr/sbin/gdm The chkconfig status for GDM shows that it's off on all run levels... could that be it? I tried running: sudo chkconfig --add gdm and just got errors... Any ideas? How can I get GDM to automatically come up again? Any/all help is appreciated! -M

  • How to go to a website on a shared server by its ip address?

    - by user1502776
    I have a few questions, please help: Fist, I can access google search just by typing http://74.125.224.211 because this is the ip address returned by nslookup. However, I could not do so with ip addresses returned from www.yahoo.com. How do I go to yahoo search page by its ip ? Another example, http://www.allaboutcircuits.com will resolve to 68.233.243.63 by DNS server, but if I go to http://68.233.243.63 I got "Hello world!" , lol ! Second, for some reason, there is something wrong with DNS resolvers with my web hosting service (it will not be fixed !!). So command like, get_file_contents("http://www.allaboutcircuits.com"); will return php_network_getaddresses: getaddrinfo failed: Name or service not known How do I get around this with IP address , 68.233.243.63 I mean somehow attach the HTTP hostname parameter to get_file_contents() ? I would like to solve this on my own side (in my code), no troubleshooting/adjustment will be done by server admin.
