  • Is there a true all-in-one solution for PHP Development?

    - by Alex R
    I'm looking for a "SINGLE INSTALLER" solution for PHP Development. Is there anything out there which will give me a nice IDE, Web Server, Debugger, Database, etc, on a single install image (*.msi or *.exe)? This of course would be completely opposite of Eclipse PDT, which requires you to search and locate a bunch of additional components which never quite work together.

  • Condor job using DAG with some jobs needing to run the same host

    - by gurney alex
    I have a computation task which is split in several individual program executions, with dependencies. I'm using Condor 7 as task scheduler (with the Vanilla Universe, due do constraints on the programs beyond my reach, so no checkpointing is involved), so DAG looks like a natural solution. However some of the programs need to run on the same host. I could not find a reference on how to do this in the Condor manuals. Example DAG file: JOB A A.condor JOB B B.condor JOB C C.condor JOB D D.condor PARENT A CHILD B C PARENT B C CHILD D I need to express that B and D need to be run on the same computer node, without breaking the parallel execution of B and C. Thanks for your help.

  • Why specifcially in my example does this "too much recursion" error occur in my JavaScript?

    - by alex
    I have been looking into this for a little while now. I have a gallery on my page, that uses Ariel Flesler's scrollTo plugin. It works fine on the home page, but not on the Contact page. In Firefox, I get the error... Too much recursion I have sorted through as much code as possible and set breakpoints in a few places. I am pretty sure it is something to do with the plugin (specifically, when it is called in the click handler). For your convenience, I am using the unpacked versions of jQuery and scrollTo plugin. What on earth am I doing wrong? Thanks for your time.

  • Is there any tips for minimising access to a public page without login?

    - by alex
    I have a page that is just a non interactive display for a shop window. Obviously, I don't link to it, and I'd also like to avoid people stumbling across it (by Google etc). It will always be powered by Chrome. I have thought of... Checking User Agent for Chrome Ensuring resolution is 1920 x 1080 (not that useful as it is a client side check) Banning under robots.txt to keep Google out of it Do you have any more suggestions? Should I not really worry about it?

  • Python - how to check if weak reference is still available

    - by Alex
    Hi all, I am passing some weakrefs from Python into C++ class, but C++ destructors are actively trying to access the ref when the real object is already dead, obviously it crashes... Is there any Python C/API approach to find out if Python reference is still alive or any other known workaround for this ? Thanks

  • What's quicker and better to determine if an array key exists in PHP?

    - by alex
    Consider these 2 examples $key = 'jim'; // example 1 if (isset($array[$key])) { doWhatIWant(); } // example 2 if (array_key_exists($key, $array)) { doWhatIWant(); } I'm interested in knowing if either of these are better. I've always used the first, but have seen a lot of people use the second example on this site. So, which is better? Faster? Clearer intent? Update Thanks for the quality answers. I now understand the difference between the 2. A benchmark states that isset() alone is quicker than array_key_exists(). However, if you want the isset() to behave like array_key_exists() it is slower.

  • Why does Eclipse crash with Xmx, XX:MaxPermSize above certain values?

    - by alex
    Running Eclipse 3.5.1, JDK 1.6.0_17 on WinXP SP3 32Bit with 3.5 gigs of RAM. I'm aware of the known Eclipse best practices, still trying to figure out eclipse.ini. This will launch: -Xmx588m and this won't: -Xmx589m. Same with -XX:MaxPermSize. Anything above -XX:MaxPermSize=140m won't launch. The screen of death is simlar to this (taken from here). Any ideas on why might this be happening?

  • .NET BinarySearch() on ArrayList of custom objects

    - by Alex
    Hi. I have an ArrayList of custom objects that have the following properties: FileName FilePath CurrentFolder TopLevelFolder I then need to do a BinarySearch (or some other quick search) on the FileName property on all the objects in the ArrayList in .NET. In other words, I need to find the object in the ArrayList with the same FileName as the one I'm searching on. Syntax for the ArrayList's BinarySearch is this; but how do you do this for an object's property in the arraylist? public static void FindMyObject( ArrayList myList, Object myObject ) { int myIndex=myList.BinarySearch( myObject ); if ( myIndex < 0 ) Console.WriteLine( "The object to search for ({0}) is not found. The next larger object is at index {1}.", myObject, ~myIndex ); else Console.WriteLine( "The object to search for ({0}) is at index {1}.", myObject, myIndex ); }

  • Javascript document.open asynchronous?

    - by Alex Schneider
    So on my site there is a Javascript function that will load a new site from the server via XMLHttpRequest. After that it replaces the current page with the new one: var post = new XMLHttpRequest(); post.open('POST', data); post.onload = function() { var do = document.open("text/html", "replace"); do.write(post.responseText); do.close(); goOn(); } function goOn() { console.log($('img:visible')); } Some could assume that after do.close() the document has changed and is ready. But it is not, e.g. if i load very much/big data/responseText the function goOn() only logs an empty result. Obviously goOn() gets in that case called before the DOM is ready to be read! Unfortunately the is no "ready" event fired after write() finished.... How can i be sure it is finished? /EDIT: goOn() logs this to Chrome Console: [prevObject: p.fn.p.init[1], context: #document, selector: "img:visible"] context: #document length: 0 prevObject: p.fn.p.init[1] selector: "img:visible" __proto__: Object[0] But if i right after that type $('img:visible') into console manually it shows me all images....

  • Advanced XPath query

    - by alex
    Hello, I have an XML file that looks like this: <?xml version="1.0" encoding="utf-8" ?> <PrivateSchool> <Teacher id="teacher1"> <Name> teacher1Name </Name> </Teacher> <Teacher id="teacher2"> <Name> teacher2Name </Name> </Teacher> <Student id="student1"> <Name> student1Name </Name> </Student> <Student id="student2"> <Name> student2Name </Name> </Student> <Lesson student="student1" teacher="teacher1" /> <Lesson student="student2" teacher="teacher2" /> <Lesson student="student3" teacher="teacher3" /> <Lesson student="student1" teacher="teacher2" /> <Lesson student="student3" teacher="teacher3" /> <Lesson student="student1" teacher="teacher1" /> <Lesson student="student2" teacher="teacher4" /> <Lesson student="student1" teacher="teacher1" /> </PrivateSchool> There's also a DTD associated with this XML, but I assume it's not much relevant to my question. Let's assume all needed teachers and students are well defined. What is the XPath query that returns the teachers' NAMES, that have at least one student that took more than 10 lessons with them? I was looking at many XPath sites/examples. Nothing seemed advanced enough for this kind of question... Thank you

  • Why does Perl lose foreign characters on Windows input - can this be fixed (if so, how) or is Perl an outdated dinosaur that just can't handle this?

    Note below how ã changes to a This is causing me a huge problem as foreign characters show up in URLs, e.g. http://pt.wikipedia.org/wiki/Cão The OS is Windows 7, 64-bit.

  • Getting text after URL in asp.net / URL Rewriting (sort of!)

    - by alex
    My app is a very simple "one page" type app- It has Default.aspx I'm basically trying to get, for example: www.myappurl.com/this is my text I want to get hold of "this is my text" from the above example. This will be displayed on the page (for now) I didn't really want to have to use any complext url rewriting things for this... (My hosting provider uses IIS6) I tried using a 404 handler, but this is a bit long winded, and i'm using shared hosting, that can't set the "execute url" on custom 404 pages. Any other ideas?

  • Align child element to bottom with CSS

    - by alex
    I have a form input, and the label spans multiple lines, and I want the corresponding checkbox to appear at the bottom (last line of the label element). Here is what I was playing with CSS .standard-form { width: 500px; border: 1px solid red; } .standard-form .input-row { overflow: hidden; margin-bottom: 0.8em; } .standard-form label { width: 25%; float: left; } .standard-form .input-container { width: 70%; float: right; } .standard-form .checkbox .input-container { display: table-cell; height: 100%; vertical-align: text-bottom; } HTML <form class="standard-form"> <div class="input-row checkbox" id="permission"> <label for="input-permission"> Do I hereby grant you permission to do whatever tasks are neccessary to achieve an ideal outcome? </label> <div class="input-container"> <input type="checkbox" id="input-permission" name="permission" value="true" /> </div> </div> </form> It is also online at JSbin. Is there any way to do this? I notice that div.input-container isn't expanding, which is the old multi column problem with CSS. I thought I could get this going with display: table-cell and vertical-align: bottom but I haven't been able to do it yet. I don't mind that IE6/7 won't render it correctly.

  • NHibernate does not update entity when repository is passed by constructor

    - by Alex
    Hi everybody, I am developing with NHibernate for the first time in conjunction with ASP.NET MVC and StructureMap. The CodeCampServer serves as a great example for me. I really like the different concepts which were implemented there and I can learn a lot from it. In my controllers I use Constructur Dependency Injection to get an instance of the specific repository needed. My problem is: If I change an attribute of the customer the customer's data is not updated in the database, although Commit() is called on the transaction object (by a HttpModule). public class AccountsController : Controller { private readonly ICustomerRepository repository; public AccountsController(ICustomerRepository repository) { this.repository = repository; } public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customerToUpdate.GivenName = "test"; //<-- customer does not get updated in database return View(); } } On the other hand this is working: public class AccountsController : Controller { [LoadCurrentCustomer] public ActionResult Save(Customer customer) { customer.GivenName = "test"; //<-- Customer gets updated return View(); } } public class LoadCurrentCustomer : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { const string parameterName = "Customer"; if (filterContext.ActionParameters.ContainsKey(parameterName)) { if (filterContext.HttpContext.User.Identity.IsAuthenticated) { Customer CurrentCustomer = DependencyResolverFactory .GetDefault() .Resolve<IUserSession>() .GetCurrentUser(); filterContext.ActionParameters[parameterName] = CurrentCustomer; } } base.OnActionExecuting(filterContext); } } public class UserSession : IUserSession { private readonly ICustomerRepository repository; public UserSession(ICustomerRepository customerRepository) { repository = customerRepository; } public Customer GetCurrentUser() { var identity = HttpContext.Current.User.Identity; if (!identity.IsAuthenticated) { return null; } Customer customer = repository.GetByEmailAddress(identity.Name); return customer; } } I also tried to call update on the repository like the following code shows. But this leads to an NHibernateException which says "Illegal attempt to associate a collection with two open sessions". Actually there is only one. public ActionResult Save(Customer customer) { Customer customerToUpdate = repository .GetById(customer.Id); customer.GivenName = "test"; repository.Update(customerToUpdate); return View(); } Does somebody have an idea why the customer is not updated in the first example but is updated in the second example? Why does NHibernate say that there are two open sessions?

  • Is an ArrayList automaticaly declared static in Java, if it is an instance variable?

    - by Alex
    I'm trying to do something like this: private class aClass { private ArrayList<String> idProd; aClass(ArrayList<String> prd) { this.idProd=new ArrayList<String>(prd); } public ArrayList<String> getIdProd() { return this.idProd; } } So if I have multiple instances of ArrayLIst<String> (st1 ,st2 ,st3) and I want to make new objects of aClass: { aClass obj1,obj2,obj3; obj1=new aClass(st1); obj2=new aClass(st2); obj3=new aClass(st3); } Will all of the aClass objects return st3 if I access the method getIdProd() for each of them(obj1..obj3)? Is an ArrayList as an instance variable automatically declared static?
